Description
CROSS-REFERENCE TO RELATED PATENT APPLICATION
[0001] This application claims the benefit of Korean Patent
Application No. 10-2016-0046991, filed on Apr. 18, 2016, in the
Korean Intellectual Property Office, the disclosure of which is
incorporated herein in its entirety by reference.
BACKGROUND OF THE INVENTION
1. Field of the Invention
[0002] The present invention relates to a heat exchanger, and more
particularly, to a heat exchanger which absorbs heat on a surface
of the heat exchanger, thereby maximizing efficiency thereof.
2. Description of the Related Art
[0003] In a heat exchanger, a fluid and a heated fluid at each
different temperature cross to accomplish heat transfer. The heat
exchanger is widely used for heating, air-conditioning, power
generation, cooling, and waste heat recovery in various
air-conditioning and heating devices including boilers and
air-conditioners.
[0004] For example, a boiler may be divided into a condensing type
and a non-condensing type. The condensing type boiler includes a
sensible heat exchanger and a latent heat exchanger, wherein the
sensible heat exchanger uses heat burnt by a burner to directly
heat heating water and the latent heat exchanger uses condensed
latent heat of exhaust gas passed through the sensible heat
exchanger to heat heating water. The non-condensing type boiler
only includes a latent heat exchanger.
[0005] In the heat exchanger for only absorbing sensible heat, a
function for handling a damp condition generated during condensing
is not needed and thus, a heat exchanger made of a copper material
showing high thermal conduction efficiency has been used. However,
in the heat exchanger for absorbing both sensible heat and latent
heat, condensing is accomplished inside the heat exchanger and
thus, a latent heat absorber therein is in a damp condition. Such a
damp condition is made since water vapor in combustion exhaust gas
is condensed and is changed from gas to fluid. Such a hanged fluid
is called condensate water. The condensate water is acidic fluid
and corrodes metal having no corrosion resistance so that a boiler
is not durable.
[0006] In addition, in the heat exchanger made of a copper material
for only absorbing sensible heat, thermal conductivity is excellent
but such corrosion is generated while in a condensed condition so
that durability of the heat exchanger is lowered. Although the
latent heat still remains in combustion gas which is passed through
the latent heat exchanger, latent heat is directly released to the
air through an exhaust air duct and thus, conventionally thermal
efficiency is low.

DETAILED DESCRIPTION OF THE INVENTION
[0013] The attached drawings for illustrating exemplary embodiments
of the present invention are referred to in order to gain a
sufficient understanding of the present invention, the merits
thereof, and the objectives accomplished by the implementation of
the present invention.
[0014] Hereinafter, the present invention will be described in
detail by explaining exemplary embodiments of the invention with
reference to the attached drawings. Like reference numerals in the
drawings denote like elements.
[0015] FIG. 1 is a perspective view of a heat exchanger 100
according to an embodiment of the present invention, FIG. 2 is a
front view of a first side part 101 of the heat exchanger 100 of
FIG. 1, FIG. 3 is a front view of a second side part 102 of the
heat exchanger 100 of FIG. 1, and FIG. 4 is a plan view of the heat
exchanger 100 of FIG. 1 viewing from the top.
[0016] Referring to FIGS. 1 through 4, the heat exchanger 100 may
include a plurality of first heat exchange pipes 110, a plurality
of second heat exchange pipes 120, a plurality of third heat
exchange pipes 130, first blisters 149, second blisters 150, and
third blisters 160.
[0017] The first heat exchange pipes 110, the second heat exchange
pipes 120, and the third heat exchange pipes 130 are connected to
each other between the first side part 101 and the second side part
102 and a path for moving a heat-exchanger fluid may be formed
inside the heat exchanger 100. The heat-exchanger fluid is flowed
in through an inlet 180 and is discharged to an outlet 190 through
the first heat exchange pipes 110, the second heat exchange pipes
120, and the third heat exchange pipes 130, wherein the
heat-exchanger fluid may be a fluid such as water. The first heat
exchange pipes 110, the second heat exchange pipes 120, and the
third heat exchange pipes 130 may be hollow pipes so that the
heat-exchanger fluid may move the inside. Also, the first heat
exchange pipes 110, the second heat exchange pipes 120, and the
third heat exchange pipes 130 may be connected to each other by
using first blisters 140, second blisters 150, and third blisters
160 so that the heat-exchanger fluid may be delivered from the
inlet 180 to the outlet 190 through the first heat exchange pipes
110, the second heat exchange pipes 120, and the third heat
exchange pipes 130. This will be described in more detail below
with reference to the first blisters 140, the second blisters 150,
and the third blisters 160.
[0018] The first heat exchange pipes 110 may be formed on the lower
surface of the heat exchanger 100, the second heat exchange pipes
120 may be spaced apart from the first heat exchange pipes 110 and
formed above the first heat exchange pipes 110, and the third heat
exchange pipes 130 may be spaced apart from the second heat
exchange pipes 120 and formed above the second heat exchange pipes
120. For example, as illustrated in FIGS. 1 through 4, eight first
heat exchange pipes 110 may be formed on the lower surface of the
heat exchanger 100, the second heat exchange pipes 120 may be each
formed above the first heat exchange pipes 110 disposed at both end
sides from among the first heat exchange pipes, and the third heat
exchange pipes 130 may be each formed above the second heat
exchange pipes 120. The first heat exchange pipes 110, the second
heat exchange pipes 120, and the third heat exchange pipes 130
according to the embodiment of the present invention may not be
formed as described above with reference to FIGS. 1 through 4 and
various numbers of heat exchange pipes may be formed in various
forms. However, since the heat exchange pipes are connected to each
other through the first blisters 140, the second blisters 150, and
the third blisters 160, which will be described below, the
heat-exchanger fluid flowed through the inlet 180 needs to be
discharged to the outlet 190.
[0019] The first blisters 140 may be each formed on the outer side
surfaces of the first side part 101 and the second side part 102
and may connect each neighboring first heat exchange pipe 110. That
is, a path of moving the heat-exchanger fluid in the first heat
exchange pipe 110 is connected to an inside space of the first
blister 140 so that the heat-exchanger fluid may move to the
neighboring first heat exchange pipe 110 through the first blister
140. The form of the first blisters 140 is not limited to that of
in FIGS. 1 through 4 described above and may vary if the
heat-exchanger fluid may move as described below with reference to
FIGS. 5 and 6.
[0020] The second blisters 150 may be formed on the outer side
surface of the first side part 101 and may each connect the first
heat exchange pipe 110 with the second heat exchange pipe 120 or
the second heat exchange pipe 120 with the third second heat
exchange pipe 130. That is, when the heat-exchanger fluid delivered
after passing through all of the first heat exchange pipes 110 is
discharged through the last first heat exchange pipe 110, the
heat-exchanger fluid may be delivered to the second heat exchange
pipe 120 disposed above the first heat exchange pipe 110 through
the second blister 150. Also, when the heat-exchanger fluid
delivered after passing through all of the second heat exchange
pipes 120 is discharged through the last second heat exchange pipe
120, the heat-exchanger fluid may be delivered to the third heat
exchange pipe 130 disposed above the second heat exchange pipe 120
through the second blister 150. For convenience of description, a
blister which connects each of the heat exchange pipes on each
different layer is defined as the second blister 150. Referring to
FIG. 2, the second blister 150 at the right side connects the first
heat exchange pipe 110 with the second heat exchange pipe 120 and
the second blister 150 at the left side connects the second heat
exchange pipe 120 with the third heat exchange pipe 130. The form
of the second blisters 150 is not limited to that of in FIGS. 1
through 4 described above, however, may vary if the heat-exchanger
fluid may move as described below with reference to FIGS. 5 and
6.
[0021] The third blisters 160 may each be formed on the outer side
surface of the second side part 102 and may connect each
neighboring second heat exchange pipe 120 or each neighboring third
second heat exchange pipe 130. That is, a path of moving the
heat-exchanger fluid in the second heat exchange pipes 120 is
connected to an inside space of the third blister 160 so that the
heat-exchanger fluid may move to the neighboring second heat
exchange pipe 120 through the third blister 160. Also, a path of
moving the heat-exchanger fluid in the third heat exchange pipes
130 is connected to an inside space of the third blister 160 so
that the heat-exchanger fluid may move to the neighboring third
heat exchange pipe 130 through the third blister 160. For
convenience of description, a blister which connects each of the
second heat exchange pipes 120 on the same layer or each of the
third heat exchange pipes 130 on the same layer is defined as the
third blister 160. Referring to FIG. 3, the third blister 160 in
the center connects each neighboring second heat exchange pipe 120
and the third blister 160 at the upper side connects each
neighboring third heat exchange pipe 130. The form of the third
blisters 160 is not limited to that of in FIGS. 1 through 4
described above, however, may vary if the heat-exchanger fluid may
move as described below with reference to FIGS. 5 and 6
[0022] The inlet 180 is connected with the first heat exchange pipe
110 disposed on one side from among the first heat exchange pipes
110 (for example, the first heat exchange pipe 110 disposed at the
far left in FIG. 1) and deliver the heat-exchanger fluid flowed
from the outside to the first heat exchange pipe 110. Also, the
outlet 190 is connected with the third heat exchange pipe 130
disposed on the other side from among the third heat exchange pipes
130 (for example, the third heat exchange pipe 130 disposed at the
far right in FIG. 1) and discharges the heat-exchanger fluid
delivered through the third heat exchange pipes 130. The positions
of the inlet 180 and the outlet 190 may vary according to the
positions of the heat exchange pipes and are not limited to that of
described above with reference to FIGS. 1 through 4.
[0023] The heat exchanger 100 described above may be formed of a
stainless steel. Also, the first heat exchange pipes 110, the
second heat exchange pipes 120, the third heat exchange pipes 130,
the first blisters 140, the second blisters 150, and the third
blisters 160 may be combined to the first side part 101 and the
second side part 102 by using brazing and thus the heat exchanger
100 according to an embodiment of the present invention may not be
twisted or thermally deformed due to thermal stress.
[0024] FIGS. 5 and 6 illustrate a moving path of a heat-exchanger
fluid in the heat exchanger 100 of FIG. 1.
[0025] Referring to FIGS. 1 through 6, the heat-exchanger fluid
flowed through the inlet 180 is delivered through the first heat
exchange pipe 110 which are connected to the inlet 180 as shown in
{circle around (1)} and is delivered to the neighboring first heat
exchange pipe 110 through the first blister 140 formed on the
second side part 102 as shown in {circle around (2)}. Then, the
heat-exchanger fluid move again toward the first side part 101
through the first heat exchange pipe 110 and is delivered to the
neighboring first heat exchange pipe 110 through the first blister
140 formed on the first side part 101 as shown in {circle around
(3)}. As described above, the heat-exchanger fluid move between the
first side part 101 and the second side part 102 and thereby, move
all of the first heat exchange pipes 110 and the first blisters
140. Such paths are illustrated in {circle around (4)} through
{circle around (8)}.
[0026] The heat-exchanger fluid delivered through the last first
heat exchange pipe 110 move to the second exchange pipe 120 through
the second blister 150 on the first side part 101 and move toward
the second side part 102 from the first side part 101 through the
second exchange pipe 120 as shown in {circle around (9)}. In
addition, as shown in {circle around (10)}, the heat-exchanger
fluid is delivered to another second exchange pipe 120 through the
third blister 160 formed on the second side part 102 and move
toward the first side part 101 from the second side part 102. As
shown in {circle around (11)}, the heat-exchanger fluid delivered
toward the first side part 101 through the second exchange pipe 120
moves to the third heat exchange pipe 130 through the second
blister 150 formed on the first side part 101 and move toward the
second side part 102 from the first side part 101 through the third
heat exchange pipe 130. Then, as shown in {circle around (12)}, the
heat-exchanger fluid is delivered to the heat exchange pipe 130
through the third blister 160 formed on the second side part 102
and move toward the first side part 101 from the second side part
102. Such delivered heat-exchanger fluid is delivered to the outlet
190 through a blister 170 formed on the first side part 101 and is
discharged to the outside through the outlet 190 as shown in
{circle around (13)}. For example, when a burner (not illustrated)
is installed on the upper part of the heat exchanger 100 and flames
and combustion gas at a high temperature generated from the burner
pass from the upper part to the lower part of the heat exchanger
100, the heat-exchanger fluid absorbs heat generated from the
flames and combustion gas at a high temperature while being
delivered from the inlet 180 and the outlet 190 and thereby, the
heat-exchanger fluid at a high temperature may be discharged
through the outlet 190.
[0027] The heat exchanger according to an embodiment of the present
invention has a blister-form and absorbs heat on a surface thereof,
thereby maximizing efficiency of the heat exchanger. In addition,
the heat exchanger according to an embodiment of the present
invention is formed of a stainless steel, thereby showing excellent
corrosion resistance. Also, the parts therein are combined to each
other by using brazing and thus, the heat exchanger may not be
twisted or thermally deformed due to thermal stress.
[0028] While the present invention has been particularly shown and
described with reference to exemplary embodiments thereof, it will
be understood by those of ordinary skill in the art that various
changes in form and details may be made therein without departing
from the spirit and scope of the present invention as defined by
the following claims.
