Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims the benefit of priority to Korean
Patent Application No. 10-2016-0009598, filed on Jan. 26, 2016 with
the Korean Intellectual Property Office, the entirety of which is
incorporated herein by reference.
TECHNICAL FIELD
[0002] The present disclosure relates to a thermoelectric element,
and more particularly, to an apparatus for manufacturing a
thermoelectric module capable of conveniently and precisely
performing alignment and arrangement of a thermoelectric
element.
BACKGROUND
[0003] A thermoelectric module uses various methods of showing an
interaction of heat with electricity and has a structure of using a
Seebeck effect of generating an electromotive force by a
temperature difference, a structure of using a Peltier effect of
absorbing (or generating) heat by a current, or the like.
[0004] The thermoelectric module may include an N-type
thermoelectric element and a P-type thermoelectric element which
are paired, an upper electrode and a lower electrode each connected
to an upper portion and a lower portion of the N-type
thermoelectric element and the P-type thermoelectric element, an
upper substrate and a lower substrate on which the upper electrode
and the lower electrode are each supported, or the like.
[0005] Technologies to align and arrange the thermoelectric
elements with respect to each electrode, a substrate, or the like
during the manufacturing of the thermoelectric module may be
required. For this purpose, the related art has used a robot arm,
an alignment mechanism, or the like.
[0006] As the scheme of using the robot arm aligns individual
thermoelectric element one by one, there is a disadvantage in that
it takes a large amount of time to align the thermoelectric
elements.
[0007] As the scheme of using an alignment mechanism requires a
separate additional process to configure a final position of the
thermoelectric element, there is a disadvantage in that the
operation of fitting the final position of the thermoelectric
element may require a large degree of work or effort.
[0008] Meanwhile, the existing thermoelectric element may have a
circular shape or a rectangular parallelepiped shape and therefore
has the problem in that the alignment of the thermoelectric
elements may be difficult or a large amount of work or effort.
[0009] Therefore, a thermoelectric element having a spherical shape
has been used to implement the precise and rapid alignment, but the
thermoelectric element having the spherical shape may be easily
separated from the fixed position even by fine vibrations during
the alignment, and therefore a defect rate of the process may be
increased.
[0010] In particular, since the thermoelectric element having the
spherical shape is hard to control a distance between a hot side
and a cold side due to structural characteristics of having the
same diameter, the thermoelectric element has the disadvantage in
that it is difficult to sufficiently secure the temperature
difference between the hot side and the cold side and the
efficiency of the thermoelectric module may be reduced.

[0038] Referring to FIG. 6, an apparatus for manufacturing a
thermoelectric module according to an exemplary embodiment of the
present disclosure may include an alignment mechanism 50 configured
to align a plurality of thermoelectric elements 11 and 12 with
respect to a plurality of electrodes 21 and 22 attached to
substrates 31 and 32.
[0039] FIGS. 1 to 4 illustrate various examples of the
thermoelectric elements 11 and 12 which may be used in the
apparatus for manufacturing a thermoelectric module according to
exemplary embodiments of the present disclosure.
[0040] Referring to FIG. 1, the thermoelectric elements 11 and
according to an exemplary embodiment of the present disclosure may
include a body 15 having a predetermined length L and a first end
portion 13 and a second end portion 14 formed at both ends of the
body 15.
[0041] The body 15 may be formed as a cylindrical shape and a
rectangular shape. The body 15 may have a length L longer than a
width W thereof. The length L of the body 15 may preferably have a
length enough to prevent an increase in resistance while securing a
temperature difference between a hot side and a cold side.
[0042] Both ends in a longitudinal direction of the body 15 may be
provided with the first end portion 13 and the second end portion
14 which may be positioned at opposite sides from each other along
the longitudinal direction of the body 15.
[0043] At least one of the first end portion 13 and the second end
portion 14 may be formed to have at least a partial non-flat
surface, such that each of the thermoelectric elements 11 and 12
may be formed in a bullet shape.
[0044] As such, according to an exemplary embodiment of the present
disclosure, as the thermoelectric elements 11 and 12 are formed in
the bullet shape, a contact area with an electrode may be
increased, such that positioning and/or adhesion of the
thermoelectric elements 11 and 12 may be greatly improved.
[0045] According to an exemplary embodiment of FIG. 1, the first
end portion 13 may be formed in a curved portion curved in a first
curvature radius R1 at one end of the body 15 and the second end
portion 14 may be formed in a curved portion curved in a second
curvature radius R2 at the other end of the body 15.
[0046] Meanwhile, the first curvature radius R1 may be equal to the
second curvature radius R2, or the first curvature radius R1 may be
different from the second curvature radius R2.
[0047] According to an exemplary embodiment of FIG. 2, a first end
portion 13a and/or a second end portion 14a of the body 15 may have
a conical surface or a pyramidal surface of which a width narrows
towards opposite ends.
[0048] According to an exemplary embodiment of FIG. 3, a first end
portion 13b or a second end portion 14b may have the same width as
the body 15 and an edge of the first end portion 13b and/or the
second end portion 14b may be formed with a round portion 16 having
a predetermined radius.
[0049] According to an exemplary embodiment of FIG. 4, the first
end portion 13b may have the same width as the body 15, a cross
section of the first end portion 13b may be formed with a flat
surface 17, and the second end portion 14b may have a curved
portion having a predetermined curvature radius.
[0050] As such, the thermoelectric elements 11 and 12 according to
an exemplary embodiment of the present disclosure may be formed in
a bullet shape where at least one end portion of the body 15 is
formed with the curved portion which includes at least partial
non-flat surface, and the contact area with the electrodes 21 and
22 may be increased by the bullet shape, such that the positioning
and/or adhesion of the thermoelectric element may be greatly
improved.
[0051] Referring to FIG. 5, the thermoelectric module 10 according
to an exemplary embodiment of the present disclosure may include
the upper substrate 31 and the lower substrate 32 spaced apart from
each other in a vertical direction and the plurality of
thermoelectric elements 11 and 12 and the plurality of electrodes
21 and 22 disposed between the upper substrate 31 and the lower
substrate 32.
[0052] The upper substrate 31 and the lower substrate 32 may
configure the hot side and the cold side and each of the substrates
31 and 32 may be made of an insulating material.
[0053] As illustrated in FIGS. 1 to 4, the plurality of
thermoelectric elements 11 and 12 may be formed in the bullet shape
in which at least one end portion is formed with at least a partial
non-flat surface.
[0054] The plurality of thermoelectric elements 11 and 12 may
include at least a pair of thermoelectric elements 11 and 12 having
opposite polarity to each other and the thermoelectric elements 11
and 12 may be made of an N-type semiconductor and a P-type
semiconductor.
[0055] Meanwhile, since the N-type semiconductor and the P-type
semiconductor each have different figures of merit (ZT), the pair
of thermoelectric elements 11 and 12 may preferably have different
cross sectional areas. Therefore, to differently set the cross
sectional areas of the thermoelectric elements 11 and 12 having the
opposite polarity to each other, the pair of thermoelectric
elements 11 and 12 may be formed to have different widths.
[0056] In particular, the first thermoelectric element 11 may be
made of the P-type semiconductor and the second thermoelectric
element 12 may be made of the N type semiconductor. Further, to
optimize the power performance of the thermoelectric module 10, a
width `a` of the first thermoelectric element 11 may be formed to
be larger than a width `b` of the second thermoelectric element
12.
[0057] The upper electrode 21 may be connected to upper ends of the
adjacent thermoelectric elements 11 and 12 and the upper electrode
21 may be formed with a groove 23 into which the first end portion
13 of the thermoelectric elements 11 and 12 is inserted.
[0058] The lower electrode 22 may be connected to lower ends of the
thermoelectric elements 11 and 12 and the lower electrode 22 may be
formed with a groove 24 into which the second end portion 14 of the
thermoelectric elements 11 and 12 is inserted.
[0059] The groove 23 of the upper electrode 21 and the groove 24 of
the lower electrode 22 may have a shape corresponding to first end
portions 13, 13a, 13b, and 13c and second end portions 14, 14a,
14b, and 14c of the thermoelectric elements 11 and 12.
[0060] FIG. 5 illustrates the thermoelectric elements 11 and 12
according to an exemplary embodiment of FIG. 1, in which the groove
23 of the upper electrode 21 and the groove 24 of the lower
electrode 22 may be formed in a groove structure that is curved
corresponding to the first and second end portions 13 and 14 formed
in the curved portions of the thermoelectric elements 11 and
12.
[0061] In addition, according to an exemplary embodiment of FIG. 2,
as the first and second end portions 13a and 14a of the
thermoelectric elements 11 and 12 are formed in a conical surface
or a pyramidal surface, the groove 23 of the upper electrode 21 and
the groove 24 of the lower electrode 22 may be formed in the groove
structure having the conical surface or the pyramidal surface.
[0062] According to an exemplary embodiment of FIG. 3, as the first
and second end portions 13b and 14b of the thermoelectric elements
11 and 12 are formed in a structure having a round portion 16, the
groove 23 of the upper electrode 21 and the groove 24 of the lower
electrode 22 may be formed in a structure in which an edge has the
round portion.
[0063] According to an exemplary embodiment of FIG. 4, as the first
end portion 13c of the thermoelectric elements 11 and 12 may be
formed in a structure having the flat surface 17, the groove 23 of
the upper electrode 21 may be formed in a structure having a flat
surface and when the second end portion 14c of the thermoelectric
elements 11 and 12 is formed in a curved structure, the groove 24
of the lower electrode 22 may be formed in the curved groove
structure.
[0064] As such, as the groove 23 of the upper electrode 21 and the
groove 24 of the lower electrode 22 may be formed in a structure
corresponding to the first and second end portions 13, 13a, 13b,
13c, 14, 14a, 14b, and 14c of the thermoelectric elements 11 and
12, the thermoelectric elements 11 and 12 may be precisely
positioned in the groove 23 of the upper electrode 21 and/or the
groove 24 of the lower electrode 22, the adhesion thereof may be
greatly improved, and thermal resistance and electric resistance
may be reduced to improve the performance of the thermoelectric
module 10.
[0065] Further, the upper electrode 21 and the lower electrode 22
may be alternately disposed to each other to smooth a flow of
current and heat.
[0066] As such, the thermoelectric elements 11 and 12 according to
an exemplary embodiment of the present disclosure may be formed in
the bullet shape in which at least one end portion of the body 15
is formed with at least a partial non-flat surface and the upper
electrode 21 and the lower electrode 22 have the grooves 23 and 24
corresponding to the end portions of the thermoelectric elements 11
and 12, such that the positioning and/or adhesion of the
thermoelectric elements 11 and 12 may be greatly improved, thereby
minimizing a defect rate during the manufacturing process of the
thermoelectric module 10.
[0067] In particular, as the length L of the thermoelectric
elements 11 and 12 is optimized, the distance between the hot side
and the cold side of the thermoelectric module 10 may be
appropriately controlled, such that the temperature difference
between the hot side and the cold side may be sufficiently
secured.
[0068] FIGS. 6 and 7 illustrate an apparatus for manufacturing a
thermoelectric module according to various exemplary embodiments of
the present disclosure.
[0069] Referring to FIG. 6, the apparatus for manufacturing a
thermoelectric module according to an exemplary embodiment of the
present disclosure may include the alignment mechanism 50
configured to align the plurality of thermoelectric elements 11 and
12 with respect to the plurality of electrodes 21 and 22 attached
to the substrates 31 and 32.
[0070] The alignment mechanism 50 may have a dispenser 60 having a
plurality of injection portions 61 and 62 and the plurality of
thermoelectric elements 11 and 12 may be inserted into the
injection portions 61 and 62 of the dispenser 60 and then inserted
into the grooves 23 and 24 of the electrodes 21 and 22 attached to
the substrates 31 and 32, such that the plurality of thermoelectric
elements 11 and 12 may be very stably aligned and arranged with
respect to the electrodes 21 and 22 of the substrates 31 and
32.
[0071] The plurality of injection portions 61 and 62 may have an
inner diameter corresponding to the width of the thermoelectric
elements 11 and 12, and an inside of each of the injection portions
61 and 62 may be formed with taper surfaces 63 and 64 so that the
thermoelectric elements 11 and 12 are stably inserted into the
injection portions 61 and 62.
[0072] In particular, the plurality of injection portions 61 and 62
may have more than one first injection portion 61 into which the
first thermoelectric element 11 is inserted and more than one
second injection portion 62 into which the second thermoelectric
element 12 is inserted.
[0073] A lower opening 61a of the first injection portion 61 may be
formed to be equal to the width `a` of the first thermoelectric
element 11 and a lower opening 62a of the second injection portion
62 may be formed to be equal to a width `b` of the second
thermoelectric element 12.
[0074] Therefore, when the first thermoelectric element 11 is first
inserted into the dispenser 60, the width `a` of the first
thermoelectric element 11 may be formed to be larger than the width
of the lower opening 62a of the second injection portion 62, such
that the first thermoelectric element 11 may not pass through the
second injection portion 62 but may pass through only the first
injection portion 61. As such, the first thermoelectric element 11
may first be inserted and thus may be stably aligned and arranged
with respect to the electrodes 21 and 22 of the substrates 31 and
32. Next, if the second thermoelectric element 12 is inserted into
the dispenser 60, the second thermoelectric element 12 may pass
through the second injection portion 62 to be stably aligned and
arranged with respect to the electrodes 21 and 22 of the substrates
31 and 32.
[0075] Further, when the plurality of thermoelectric elements 11
and 12 are aligned with respect to the electrodes 21 and 22 of the
substrates 31 and 32 by the dispenser 60, a distance `d` between
the dispenser 60 and the electrodes 21 and 22 may be set to be
smaller than the length `L` of the thermoelectric elements 11 and
12, such that the thermoelectric elements 11 and 12 may be
precisely aligned with respect to the electrodes 21 and 22 of the
substrates 31 and 32.
[0076] Further, the alignment mechanism 50 may further include an
oscillator 65 connected to one side of the dispenser 60, and the
dispenser 60 may be shaken horizontally by the oscillator 65, such
that the plurality of thermoelectric elements 11 and 12 may be
precisely and easily aligned with respect to the electrodes 21 and
22 of the substrates 31 and 32.
[0077] Meanwhile, prior to the alignment operation of the
thermoelectric elements 11 and 12 by the dispenser 60, the grooves
23 and 24 of the electrodes 21 and 22 may be previously applied
with a brazing filler (powder or film form) which may be an
adhesive. The brazing filler may be heated to bond the
thermoelectric elements 11 and 12 to the electrodes 21 and 22. The
grooves 23 of the electrodes 21 and 22 adjacent to the hot side may
be applied with the brazing filler having a high melting point and
the grooves 24 of the electrodes 21 and 22 adjacent to the cold
side may be applied with the brazing filler having a low melting
point.
[0078] Referring to FIG. 7, an apparatus for manufacturing a
thermoelectric module according to an exemplary embodiment of the
present disclosure may further include a bonding mechanism 70 for
bonding the thermoelectric elements 11 and 12 to the grooves 23 and
24 of the electrodes 21 and 22 after the thermoelectric elements 11
and 12 are aligned by the alignment mechanism 50.
[0079] The bonding mechanism 70 may have a heating cartridge 75
generating heat and a plurality of heat conducting portions 71 and
72 extending from the heating cartridge 75.
[0080] The plurality of heat conducting portions 71 and 72 may be
individually inserted into the plurality of injection portions 61
and 62 to transfer heat to the grooves 23 and 24 of the electrodes
21 and 22 and the thermoelectric elements 11 and 12. The
thermoelectric elements 11 and 12 may be firmly bonded to the
grooves 23 and 24 of the electrodes 21 and 22 while the brazing
filler previously applied to the grooves 23 and 24 of the
electrodes 21 and 22 is melted by the transferred heat.
[0081] The plurality of heat conducting portions 71 and 72 may
include a first heat conducting portion 71 inserted into the first
injection portion 61 and a second heat conducting portion 72
inserted into the second injection portion 62.
