Description
[0001] The invention relates to registers for a heating element,
and heating elements having such registers.
[0002] There are numerous types of heating elements. A classical
heating element contains two distributor lines, between which a
plurality of connecting tubes extend which fluidically connect the
first distributor line, also referred to as the supply distributor,
to the second distributor line, also referred to as the return
distributor.
[0003] To increase the specific heat capacity of a heating element,
i.e., the thermal output released by radiation and convection to a
space per unit area of the front elevation of the heating element,
it is known to provide multicolumn heating elements in which
multiple registers made up of connecting tubes extend essentially
in parallel to one another between the supply distributor and the
return distributor.
[0004] On the one hand, the manufacture of multicolumn heating
elements of this type is relatively complicated.
[0005] On the other hand, the thickness of such multicolumn heating
elements, measured perpendicular to the front elevation, increases
with an increasing number of registers (three-column, four-column,
five-column, six-column), as the result of which the flat
board-like or panel-like character of such high-performance
multicolumn heating elements is lost.
[0006] The object of the invention is to allow multicolumn heating
elements having the design described at the outset, which on the
one hand have a small thickness and still have excellent thermal
output, and on the other hand may be cost-effectively
manufactured.
[0007] To achieve this object, the invention provides a tube
register (RR) for a heat exchanger (WT), in particular a heating
element or cooling element, through which a heat transfer fluid may
flow, and which has two distributor lines (1, 2), between which a
plurality of connecting tubes (3) extend which fluidically connect
the first distributor line, also referred to as the supply
distributor (1), to the second distributor line, also referred to
as the return distributor (2), the tube register having a linear
supply distributor (1) and a linear return distributor (2) running
in parallel thereto, between which a plurality of connecting tubes
(3), situated in a plane, extend, the first ends (3a) of the
connecting tubes (3) in each case being fluidically connected to
the supply distributor (1), and the second ends (3b) of the
connecting tubes (3) in each case being fluidically connected to
the return distributor (2). According to the invention, the
connecting sites (P1) between the supply distributor (1) and the
connecting tubes (3) are situated eccentrically, relative to the
center axis (M1) of the supply distributor (1), on the supply
distributor (1), and the connecting sites (P2) between the return
distributor (2) and the connecting tubes (3) are situated
eccentrically, relative to the center axis (M2) of the return
distributor (2), on the return distributor (2).
[0008] The tube register (RR) according to the invention, in a
projection plane orthogonal to the longitudinal axis of the supply
distributors and return distributors, has the appearance of a
structure having the approximate shape of a rectangular letter C,
the projection of the supply distributor (1) forming the upper
horizontal section of the C, the projection of the return
distributor (2) forming the lower horizontal section of the C, and
the projection of the connecting tubes (3) forming the vertical
section of the C.
[0009] The tube register according to the invention therefore has
only two planes of symmetry. A first plane of symmetry extends
orthogonally with respect to the longitudinal axis of the supply
distributor (1) and orthogonally with respect to the longitudinal
axis of the return distributor (2). A second plane of symmetry
extends orthogonally with respect to the longitudinal axis of the
connecting tubes (3). The tube register according to the invention
is asymmetrical with respect to any third plane which extends in
parallel to the longitudinal axes of the supply distributor (1), of
the return distributor (2) and of the connecting tubes (3).
[0010] Due to this asymmetry of the tube register (RR) according to
the invention, by combining multiple (n) tube registers (RR1, RR2,
. . . , RRn) according to the invention, a wide variety of heat
exchangers (WT) according to the invention may be manufactured,
each of which has different dimensions and thermal properties with
regard to radiation output and convection, depending on the
relative configuration of the individual registers (RR1, RR2, . . .
, RRn) with respect to one another.
[0011] In addition, using the tube register (RR) according to the
invention as a modular base element, a wide variety of heat
exchangers (WT) according to the invention may be cost-effectively
manufactured.
[0012] According to one particularly preferred embodiment, the tube
register (RR) is made of polymer material.
[0013] As a result, particularly lightweight heat exchangers (WT)
according to the invention may be manufactured, which have a very
large ratio of the thermal output (radiation+convection) of the
heat exchanger to the mass of the heat exchanger.
[0014] The supply distributor (1) and the return distributor (2)
may be made of a first polymer material, while the connecting tubes
(3) may be made of a second polymer material. Alternatively, the
supply distributor (1) and the return distributor (2) as well as
the connecting tubes (3) may be made of the same polymer
material.
[0015] The supply distributor (1) and the return distributor (2) as
well as the connecting tubes (3) are preferably tubes that are
manufactured by extrusion, and welded or glued to one another at
the connecting sites (P1, P2). In the case of a weld connection,
ultrasonic welding is preferred.
[0016] Moreover, the invention provides a heat exchanger (WT), in
particular a heating element or cooling element, which has multiple
adjacently situated tube registers (RR1, RR2, . . . , RRn)
according to one of the preceding paragraphs.
[0017] Due to the asymmetry of the tube registers (RR1, RR2, . . .
, RRn) according to the invention, the combination of multiple (n)
such tube registers to form a heat exchanger (WT) allows a wide
variety of heat exchangers (WT) according to the invention, which
have different dimensions and thermal properties with regard to
radiation output and convection, depending on the relative
configuration of the individual registers (RR1, RR2, . . . , RRn)
with respect to one another. This wide variety of heat exchangers
(WT) according to the invention may therefore be cost-effectively
manufactured.
[0018] In the heat exchanger (WT) according to the invention, the
adjacently situated fluid inlets of the adjacently situated supply
distributors (1) are preferably fluidically connected to one
another by means of a supply collection member (S1) which
establishes a fluid connection to the supply line connection (A1)
of the heat exchanger (WT), and the adjacently situated fluid
outlets of the adjacently situated return distributors (2) are
fluidically connected to one another by means of a return
collection member (S2) which establishes a fluid connection to the
return line connection (A2) of the heat exchanger (WT).
[0019] The supply collection member (S1) and the return collection
member (S2) are preferably made of a polymer material, and are
preferably manufactured by injection molding.
[0020] The asymmetry of the tube registers (RR1, RR2, . . . , RRn)
according to the invention and the multiple options for arranging
these tube registers, which always have identical shapes, relative
to one another as inexpensive base elements are a first factor
which contributes toward achieving the object according to the
invention.
[0021] The diversity of the heat exchanger variants according to
the invention is made possible by a corresponding diversity of
collection members (1, 2). Due to the above-described symmetries of
each individual tube register (RR) and the corresponding symmetries
of any tube register combinations, and due to the connection of the
supply line at the top left and the connection of the return line
at the bottom right, the configurations of the adjacently situated
fluid inlets of the adjacently situated supply distributors (1) are
point-symmetrical with respect to the configurations of the
adjacently situated fluid outlets of the adjacently situated return
distributors (2).
[0022] The supply collection member (1) and the return collection
member (2) may thus have identical shapes. This is a second factor
which contributes toward achieving the object according to the
invention.
[0023] As a result, assembling a heat exchanger according to the
invention only requires identical tube registers according to the
invention in the required number, and two likewise identical
collection members for combining the supply distributors and the
return distributors. On account of their compact dimensions, the
collection members may be cost-effectively manufactured by
injection molding.
[0024] The supply distributors (1) are preferably glued or welded
to the supply collection member (S1) in the area of their fluid
connection to same, and the return distributors (2) are preferably
glued or welded to the return collection member (S2) in the area of
their fluid connection to same.
[0025] The heat exchanger (WT) may have a plate-like cover element,
which is preferably made of a metal mesh and/or a metal sheet, at
least on one of its large surfaces i.e., on its front surface (5)
and/or on its rear surface (6).
[0026] This contributes to homogenization of the surface
temperature of the heat exchanger, which is operated as a wall
heating element, for example, and to an intensified chimney effect
in its interior.
