Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a heat exchanger, and more
particularly to a heat exchanger having two or more different or
uneven fluid flowing paths or passages having different cross
section areas or different volumes for guiding and allowing the
heat medium and/or other heat exchanging fluids to flow through the
fluid flowing paths or passages with different flowing speeds
and/or different contact areas, and for facilitating the heat
exchanging effect.
[0003] 2. Description of the Prior Art
[0004] Typical heat exchangers comprise a receptacle including a
chamber formed therein for receiving a heat medium, such as water
or fluid, and an inlet and an outlet provided therein for allowing
the heat medium or water or fluid to flow into and out of the
chamber of the receptacle. The receptacle further includes a number
of plates or boards or housings disposed therein, and superposed
with each other, and each having a wavy structure arranged to allow
the heat medium or water or fluid to flow through the wavy plates
or boards or housings, and to allow the heat medium or water or
fluid to be heat exchanged indirectly with the other heat medium
within the chamber of the receptacle.
[0005] The formation or the provision of the wavy structure of the
plates or boards or housings is arranged for increasing the
contacting area between the plates or boards or housings and the
heat media, and for increasing the heat exchanging effect. The
plates or boards or housings of the receptacle further includes one
or more openings or passages formed therein, for controlling or
guiding the heat medium to suitably flow through the plates or
boards or housings.
[0006] The plates or boards or housings may be disposed and
superposed with each other, and the plates or boards or housings
may be randomly or selectively disposed one above the other.
Normally, two flowing paths or passages are formed in the
receptacle and include the same cross section area or the same
volume for receiving two different heat exchanging fluids and for
allowing the different heat exchanging fluids to evenly flow
through the fluid flowing paths or passages with the same flowing
speed and for allowing the different heat exchanging fluids to
uniformly contacted with each other.
[0007] However, the heat dissipating or absorbing or exchanging
rate of the different heat exchanging fluids, such as water, heat
or cold media, or the like may be different from each other, such
that the heat exchanging rate between the different heat exchanging
fluids may be different, and such that the heat exchanging effect
may not be facilitated.
[0008] The present invention has arisen to mitigate and/or obviate
the afore-described disadvantages of the conventional heat
exchanging flowing paths or passages for the heat exchangers.
SUMMARY OF THE INVENTION
[0009] The primary objective of the present invention is to provide
a heat exchanger including two or more different or uneven fluid
flowing paths or passages having different cross section areas or
different volumes for guiding and allowing the heat medium and/or
other heat exchanging fluids to flow through the fluid flowing
paths or passages with different flowing speeds and/or different
contact areas, and for facilitating the heat exchanging effect.
[0010] In accordance with one aspect of the invention, there is
provided a heat exchanger comprising a first plate set including a
first plate and a second plate disposed below the first plate for
forming at least one conduit between the first and the second
plates of the first plate set, and a second plate set including a
first plate disposed below the second plate of the first plate set,
for forming at least one duct between the first plate of the second
plate set and the second plate of the first plate set, the first
and the second plates of the first and the second plate sets
include an opening communicating and coupled to the conduit formed
between the first and the second plates of the first plate set for
receiving a first medium, and the first and the second plates of
the first and the second plate sets include an orifice
communicating and coupled to the duct formed between the first
plate of the second plate set and the second plate of the first
plate set for receiving a second medium and for separating the
first medium and the second medium from each other, and for
allowing the first medium to have a greater flowing quantity than
that of the second medium.
[0011] The first plates and the second plates each include a wavy
structure having a plurality of depressions formed between a
plurality of bulges, and the depressions of the first plate of the
first plate set are disposed above the bulges of the second plate
of the first plate set for forming the conduit between the first
and the second plates of the first plate set, and the depressions
of the second plate of the first plate set are disposed above the
bulges of the first plate of the second plate set for forming the
duct between the second plate of the first plate set and the first
plate of the second plate set.
[0012] The depressions of the first plates of the first and the
second plate sets and the bulges of the second plates of the first
and the second plate sets include a triangular cross section, and
the bulges of the first plates of the first and the second plate
sets and the depressions of the second plates of the first and the
second plate sets include a trapezoidal cross section.
[0013] Further objectives and advantages of the present invention
will become apparent from a careful reading of the detailed
description provided hereinbelow, with appropriate reference to the
accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0018] Referring to the drawings, and initially to FIGS. 1-2, a
heat exchanger 1 in accordance with the present invention comprises
one or more heat exchanging assemblies or plate sets 10, 11
alternatively superposed with each other and each including two
heat exchanging boards or plates 12, 13 disposed and superposed
with each other for allowing the upper or first plate 12 to be
disposed above the lower or second plate 13 which is disposed above
the upper or first plate 12 of the other or lower plate set 11. The
plates 12-13 each include a wavy structure 20 arranged to allow the
heat medium or water or fluid to flow through the wavy boards or
plates 12-13 with an increased contacting area, and to allow the
heat medium or water or fluid to be heat exchanged with the other
heat medium, such as ambient air, other heat media or water or
fluid or the like.
[0019] The formation or the provision of the wavy structure 20 of
the boards or plates 12-13 is provided for increasing the
contacting area between the heat media flowing through the boards
or plates 12-13, and for increasing the heat exchanging effect. For
example, the boards or plates 12-13 each include one or more
depressions 21, 23 formed or defined between one or more bulges 22,
24 respectively, in which the depressions 21 of the upper or first
plate 12 are arranged and secured and disposed above the bulges 24
of the lower or second plate 13 for forming one or more conduits 30
between the bulges 22 and the depressions 23 of the upper or first
plate 12 and the lower or second plate 13 of one of the plate sets
10, 11.
[0020] The conduits 30 formed between the upper or first plate 12
and the lower or second plate 13 of the upper or one of the plate
sets 10, 11 are communicating or coupled with each other and
provided for receiving various cold or heat media therein.
Similarly, the depressions 23 of the lower or second plate 13 are
arranged and secured and disposed above the bulges 22 of the first
or upper plate 12 of the other or lower plate set 11 for forming
the ducts 31 between the bulges 24 of the lower or second plate 13
of the upper plate set 10 and the depressions 21 of the upper or
first plate 12 of the lower plate set 11. The ducts 31 formed
between the lower or second plate 13 of the upper plate set 10 and
the upper or first plate 12 of the lower plate set 11 are also
communicating or coupled with each other and provided for receiving
various cold or heat media therein. The heat media may be selected
from water, various fluid, ambient air, or other heat media.
[0021] The plates 12-13 each further include one or more openings
14 and one or more orifices 15 formed in such as the corner areas
thereof, and aligned with each other, for controlling or guiding
the heat medium to suitably flow through the openings 14 or the
orifices 15 of the boards or plates 12-13. For example, as shown in
FIG. 1, the openings 14 of the plates 12-13 are communicating or
coupled to the conduits 30 that are formed between the upper or
first plate 12 and the lower or second plate 13 for receiving one
of the cold or heat media 80 therein, such as water or other
fluid.
[0022] The orifices 15 of the plates 12-13 are communicating or
coupled to the ducts 31 that are formed below the second or lower
plate 13, or formed between the second or lower plate 13 of the
upper set 10 and the upper or first plate 13 of the lower set 11
for receiving the other cold or heat media 88 therein, such as
ambient air or other heat media that are different from the cold or
heat media 80 flowing through the conduits 30 of the plates 12-13.
The cold or heat media 80, 88 may thus flow through the conduits 30
and the ducts 31 of the plates 12-13 respectively and separately,
and will not be mixed or blended with each other, for heat
exchanging with each other.
[0023] The first cold or heat medium 80 may flow through the
conduits 30 and the openings 14 of the plates 12-13 respectively,
and the second cold or heat medium 88 may flow through the ducts 31
and the orifices 15 of the plates 12-13 respectively, and the first
and the second cold or heat media 80, 88 may be heat exchanged with
each other via the plates 12-13 that are preferably made of
excellent heat exchanging or conductive materials, such as metal,
aluminum, copper, or the like.
[0024] It is to be noted that the conduits 30 of the plates 12-13
may include a volume or cross section or area greater or more than
that of the ducts 31 of the plates 12-13 for allowing the first
cold or heat medium 80 to have a greater flowing quantity than that
of the second cold or heat medium 88, and for allowing the cold or
heat medium 80 to have a greater contact area with the other cold
or heat medium 88, and thus for allowing the cold or heat media 80,
88 of different heat exchanging characteristics, such as the
different heat dissipating or absorbing or exchanging rate, to flow
through the conduits 30 of the plates 12-13 and the ducts 31 of the
plates 12-13 that have different volumes or cross sections or
areas.
[0025] For example, the depressions 21 and the bulges 24 of the
plates 12-13 for forming the conduits 30 include a smaller or
triangular cross section, and the bulges 22 and the depressions 23
of the plates 12-13 for forming the ducts 31 include a greater or
trapezoidal cross section, and the depressions 21 of the plates 12
are aligned with and attached to the bulges 24 of the other plates
13, and the bulges 22 of the plates 12 are aligned with and
attached to the depressions 23 of the other plates 13 for forming
the conduits 30 and the ducts 31 of different volume or cross
section or area between the plates 12, 13.
[0026] The heat exchanger in accordance with the present invention
may include a number sets 10 of plates 12-13 alternatively
superposed with each other. The plates 12-13 each preferably
includes a mirror symmetric structure or identical structure to
allow the plates 12-13 to be made with the same mold device (not
shown), such that the manufacturing cost for the heat exchanger may
be suitably decreased.
[0027] Accordingly, the heat exchanger in accordance with the
present invention includes two or more different or uneven fluid
flowing paths or passages having different cross section areas or
different volumes for guiding and allowing the heat medium and/or
other heat exchanging fluids to flow through the fluid flowing
paths or passages with different flowing speeds or flowing
quantities and/or different contact areas, and for facilitating the
heat exchanging effect.
[0028] Although this invention has been described with a certain
degree of particularity, it is to be understood that the present
disclosure has been made by way of example only and that numerous
changes in the detailed construction and the combination and
arrangement of parts may be resorted to without departing from the
spirit and scope of the invention as hereinafter claimed.
