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 an improved flow
controlling or guiding structure or device, for suitably sealing or
guiding the heat medium or fluid to flow through the heat
exchanger, and for allowing heat exchanging plates or boards or
housings to be changeably disposed and superposed above other.
[0003] 2. Description of the Prior Art 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.
[0004] 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.
[0005] 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.
However, the openings or passages formed within the plates or
boards or housings may not be suitably aligned with each other when
different plates or boards or housings are disposed above the
other, and the plates or boards or housings may include different
structure, such that two or more mold devices are required to form
and to make different plates or boards or housings.
[0006] The present invention has arisen to mitigate and/or obviate
the afore-described disadvantages of the conventional heat
exchanging plates or boards or housings for the heat
exchangers.
SUMMARY OF THE INVENTION
[0007] The primary objective of the present invention is to provide
a heat exchanger including an improved flow controlling or guiding
structure or device, for suitably sealing or guiding the heat

housing including an opening formed therein, and including an upper
surface having a peripheral recess formed therein and located
around the opening thereof, and including a peripheral wall
extended therefrom and located between the peripheral recess and
the opening thereof, and a peripheral flange extended into the
opening thereof, the second housing including a duct extended
through the peripheral recess thereof and having a pathway formed
therein, the groove of the first housing and the pathway of the
second housing form a flowing passage altogether for allowing a
heat medium to flow through the peripheral swelling and the
peripheral recess of the first and the second housings when the
second housing is disposed above the first housing, and the
peripheral flanges of the first and the second housings are
superposed and contacted with each other when the first housing is
disposed above the second housing, to guide the heat medium to flow
through the peripheral swelling and the peripheral recess of the
first and the second housings only when the second housing is
disposed above the first housing.
[0010] The peripheral flange of the first housing is preferably
parallel to and in the same level of the upper surface thereof. The
first housing includes an inner peripheral surface formed thereon
and preferably inclined relative to the upper surface thereof, and
having the peripheral flange extended from the inner peripheral
surface thereof, to form and define the opening thereof. The first
housing includes an inner peripheral channel formed and defined
within the peripheral swelling.
[0011] The peripheral flange of the second housing is also
preferably parallel to and in the same level of the upper surface
thereof. It is also preferable that the peripheral flange of the
second housing is extended from the peripheral wall thereof, and
extended into the opening thereof, to form or define the opening
thereof.
[0012] 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.
BRIEF DESCRIPTION OF THE DRAWINGS
[0013] FIG. 1 is a perspective view illustrating two superposed
heat exchanging plates or boards or housings for a heat exchanger
in accordance with the present invention;
[0014] FIG. 2 is an enlarged partial perspective view of the heat

[0015] FIG. 3 is an enlarged partial perspective view similar to
FIG. 2, illustrating the operation of the heat exchanger.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0016] Referring to the drawings, and initially to FIG. a heat
exchanger in accordance with the present invention comprises a
number of heat exchanging plates or boards or housings 10, 30
disposed and superposed with each other, and each having a wavy
structure 80 arranged to allow the heat medium or water or fluid to
flow through the wavy plates or boards or housings 10, 30 with an
increased contacting area, and to allow the heat medium or water or
fluid to be heat exchanged indirectly with the other heat medium,
such as ambient air or the like (not shown).
[0017] The formation or the provision of the wavy structure of the
plates or boards or housings is also provided 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 10, 30 each further includes one or
more passages or openings 11, 31 formed therein, and aligned with
each other, for controlling or guiding the heat medium to suitably
flow through the passages or openings 11, 31 of the plates or
boards or housings 10, 30.
[0018] For example, the housings 10 each includes an upper surface
12 having a circular or peripheral swelling 13 extended upwardly
therefrom, and formed or located around each of the openings 11
thereof. The peripheral swelling 13 includes a flat circular or
peripheral upper surface 14 formed thereon, and an inclined inner
peripheral surface 15 formed thereon, and further includes a
peripheral flange 16 extended into the opening 11 thereof, and
preferably parallel to or in the same level of the upper surface 12
thereof, in order to form or define an inner peripheral channel 17
within the peripheral swelling 13 (FIG. 3).
[0019] The other housings 30 each also includes an upper surface 32
having a circular or peripheral recess 33 formed therein, and
formed or located around each of the openings 31 thereof, and
includes an inclined peripheral wall 34 extended therefrom and
located between the peripheral recess 33 and the opening 31
thereof, and having a peripheral flange 35 extended into the
opening 31 thereof and preferably parallel to or in the same level
of the upper surface 32 thereof, in order to form or define the
peripheral recess 33 and the opening 31 thereof.
[0020] It is to be noted that the peripheral flanges 16, 35 of the
housings 10, 30 are parallel to or in the same level of the upper
surfaces 12, 32 thereof respectively, to allow the upper surfaces
12, 32 and the peripheral flanges 16, 35 of the housings 10, 30 to
be snugly superposed or contacted with each other, when the housing
10 is disposed above the other housing 30 (FIG. 3). In addition,
the peripheral flanges 16, 35 of the housings 10, 30 include a
complete or enclosed circular or peripheral structure having no
notches or openings formed therein, to prevent the heat medium to
flow through the peripheral flanges 16, 35 of the housings 10, 30,
in order to form a peripheral compartment 88 by the inner
peripheral channel 17 of the peripheral swelling 13 and the
peripheral recess 33 of the housing 30 (FIG. 3).
[0021] Relatively, as shown in FIG. 2, the housing 30 includes a
circular or peripheral casing 36 extended downwardly from the upper
surface 32 thereof, and also formed or located around the opening
31 thereof, for forming or defining the peripheral recess 33
thereof, and for snugly superposing or contacting or engaging with
the peripheral swelling 13 of the housing 10 when the other housing
30 is disposed above the housing 10 (FIG. 2).
[0022] As shown in FIGS. 2 and 3, the housing 10 includes a groove
18 formed through the peripheral swelling 13 thereof, for allowing
the heat medium 90 to laterally flow through the peripheral
swelling 13 via the groove 18 thereof (FIG. 2). The other housing
30 includes a duct 37 extended through the peripheral recess 33
thereof, and having a pathway 38 formed therein (FIG. 2), for
allowing the heat medium 90 to laterally flow through the
peripheral recess 33 thereof via the pathway 38 of the duct 37
(FIG. 3). The groove 18 and the pathway 38 of the two superposed
housings 10, 30 will thus form a flowing passage 18, 38 altogether
for allowing the heat medium 90 to laterally flow through the
peripheral swelling 13 and the peripheral casing 36 of the two
housings 10, 30 that are superposed with each other (FIG. 2).
[0023] Accordingly, the heat medium 90 flowing into the openings
11, 31 of the housings 10, 30 may be controlled or guided to
suitably flow through the groove 18 and the pathway 38 of the
housings 10, 30 respectively when the housing 30 is disposed above
the other housing 10 (FIG. 2), and may not flow through the flowing
passage that is formed by the groove 18 and the pathway 38 of the
housings 10, 30 when the housing 10 is disposed above the other
housing 30 (FIG. 3). The groove 18 and the pathway 38 of the
housings 10, 30 may be coupled to the other heat exchanging tubings
or pipings respectively (not shown), for suitably controlling or
guiding the heat medium 90 to flow to the other heat exchanging
devices or elements (not shown) or the like.
[0024] The heat exchanger in accordance with the present invention
may include a number of housings 10 and a number of housings 30
alternatively superposed with each other. The housings 10, 30 each
preferably includes a mirror symmetric structure, and/or the
housings 10, 30 include an identical structure, to allow the
housings 10, 30 to be made with the same mold device (not shown),
such that the manufacturing cost for the heat exchanger may be
suitably decreased.
[0025] Accordingly, the heat exchanger in accordance with the
present invention includes an improved flow controlling or guiding
structure or device, for suitably sealing or guiding the heat
medium or fluid to flow through the heat exchanger, and for
allowing heat exchanging plates or boards or housings to be
changeably disposed and superposed above other.
[0026] 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.
