Description

Oblong type heat exchanger

The present invention relates to a heat exchanger, and more particularly, by stacking two oblong heat sinks in a plate shape with each other, the two fluid movement paths where the fluid moves are adjacent to each other to form a heat exchange effect. The present invention relates to an olong type heat exchanger which improves the pressure and is operated under high pressure by dispersing pressure due to mutual adjoining of the fluid movement furnace.

In general, the basis of heat exchange is to cool the target fluid due to the phenomenon of thermal equilibrium by exchanging heat from high temperature to low temperature by direct or indirect contact with each other in the space where fluid A and B flow. Or heating.

Therefore, the main issue of heat exchangers is that the heat exchange between the contacting fluids must be carried out in a short time, and the heat exchange must be carried out only between each other without dissipating heat elsewhere.

The heat exchanger according to the prior art is introduced under the title of heat exchanger in the Republic of Korea Patent Publication No. 10-328275.

As shown in Figures 1 to 4, the prior art is a plurality of first heat transfer plate (S1) and the second heat transfer plate (S2) forming a quadrilateral through the fold line (L1) and bone fold line (L2). By alternately speaking, the folded sheet material 21 is bent in the shape of tortuous lines in the mountain and valley line L1 and L2, so that the hot fluid passage 4 and the low temperature fluid passage 5 extending in the axial direction are circumferential. Alternately in the direction,

The radial outer casing 6 and the outer conduit members 8o and 10o are soldered to the plurality of crease lines L1 located radially outward, and to the multiple corrugated lines L2 located radially inward. By brazing the radially inner casing 7 and the inner conduit members 8i and 10i, the radial outer and inner circumferences of the axially extending high temperature fluid passage 4 and the low temperature fluid passage 5 are closed, The high temperature fluid introduction and discharge conduits (13, 14) and the low temperature fluid introduction and discharge conduits (17, 18) leading to the high temperature fluid passage (4) are formed to form the high temperature fluid passage (4). After forming the hot fluid passage inlet 11 and the hot fluid passage outlet 12 in the openings at both ends of the axial direction,

At the same time, the front and rear convex portions 24F and 24R protruding from the axial ends of the low temperature fluid passage 5 to the first and second heat transfer plates S1 and S2 are soldered to each other to close and close the high temperature fluid passage exit. A low temperature fluid passage inlet 15 is formed on one side of the radially outer casing 6 and the outer conduit members 8o, 10o and the radially inner casing 7 and the inner conduit members 8i, 10i on the (12) side. And a low temperature on the other side of the radial outer casing 6 and the outer conduit members 8o and 10o and the radial inner casing 7 and the inner conduit members 8i and 10i at the high temperature fluid passage inlet 11 side. A heat exchanger having a fluid passage outlet 16 formed therein.

However, the above prior art involves the problems described below.

First, the fluid flowing along the low temperature fluid passage and the high temperature fluid passage has a problem that the first and second protrusions formed at different intervals interfere with the flow of the fluid and thus the fluid does not have a constant flow.

Second, the pressure of the fluid flowing through the high temperature fluid passage and the low temperature fluid passage is different, the first heat exchange plate and the second heat transfer plate is distorted by the pressure difference, so that the flow of the fluid is not accurate, the heat exchange efficiency is reduced There is a problem.

Third, the low temperature fluid passage inlet and the low temperature fluid passage outlet must be separately installed wherever the low temperature fluid passage is formed, and there is a problem that the combustion gas passage inlet and the combustion gas passage outlet must be separately formed in each high temperature fluid passage.

In another conventional art, there is a heat exchanger formed by stacking a heat exchanger plate formed in a circular plate shape, but the heat exchanger of the circular plate shape is evenly distributed evenly, but heat transfer of a large temperature gradient is impossible, and the heat capacity is not large. Therefore, there is a problem in that heat transfer such as gas, which is a bulky fluid, is impossible.

Therefore, the present invention has been made to solve the above problems, by forming a plate-shaped oval (oblong type) heat sink between each other by forming two separate fluid movement paths adjacent to each other to move the fluid separately An object of the present invention is to provide an olong type heat exchanger for improving the heat exchange effect.

In addition, it is another object of the present invention to provide an Olong type heat exchanger which is operated under high pressure by dispersing pressure by contacting each other between the fluid movement path and the fluid movement path of the heat sink.

In addition, it is an object of the present invention to provide an Olong type heat exchanger that eliminates the trouble of forming a plurality of inlets and outlets by forming two inlet and outlet in one inlet and outlet.

As shown, the heat exchanger according to the present invention is largely the heat sink 100, the heat sink group 200, the welding unit 110, the main body 120, the first flow path 130 and the second flow path 140.

First, the heat sink 100 will be described.

The heat sink 100 is formed in an approximately oval shape (oblong type), the inlet hole 101 is formed in the adjacent portion. Here, the inlet hole 101 is usually composed of two places where the fluid is introduced and the outlet.

In addition, the heat sink 100 has an extended depression 102 having a shape recessed downwardly at a predetermined inclination with respect to the inflow hole 101 at equal intervals. At the same time, an extension protrusion 103 having a shape protruding upward is formed between the extension depressions 102 by the formation of the extension depressions 102.

Here, the extension depression portion 102 and the extension protrusion 103 formed on the heat sink 100 are named names in the form, and when the heat sink 100 is turned over, the extension depression portion 102 becomes the extension protrusion 103 and extends. The protrusions 103 are symmetrically formed in the form of extending depressions.

In addition, in the case of the heat dissipation plate 100, the shape is substantially oval (oblong type), the heat dissipation plate 100 of the elliptical shape, the thermal efficiency is increased by a considerable length (thermal length) compared to the original heat dissipation plate.

On the other hand, the inlet hole 101 adjacent portion and the end adjacent portion of the heat sink 100 is formed flat, it is easy to form a weld 110 to be described later.

Next, the heat dissipation plate 100 is stacked to form a heat dissipation plate group 200. The formation of the heat dissipation plate group 200 is formed by stacking a plurality of heat dissipation plates 100.

First, the inlet hole 101 and the outlet hole 122 of the main body 120 to be described later are connected to the inlet hole 101 of the side heat sink 201 formed on the left or right end surface of the heat sink group 200. In the case of the main body 120 communicating with the side heat sink 201, when the inlet 121 is formed at the lower side, the outlet 122 is formed at the upper side.

In addition, a plurality of heat sinks are stacked between the side heat sinks 201.

That is, a plurality of heat sinks are stacked in such a manner that the first heat sink 202 and the second heat sink 203 are alternately inserted, and the inflow holes 101 of the stacked heat sinks are formed to communicate with each other. Here, the first and second heat dissipation plates 202 and 203 are named for convenience, but the shape or shape of the heat dissipation plate is not changed.

That is, heat sinks are stacked in order of first 202, second 203, first 202, second 203, first 202, second 203,... do.

In this case, the adjacent heat dissipation bars are in contact with each other, and a portion protruding by forming an extension protrusion 103 protruding from the first heat dissipation plate 202 and an extension recess 102 of the second heat dissipation plate 203. These are in contact with each other.

The extension protrusions 103 and the extension depressions 102 are formed to be in contact with each other by being inclined.

Therefore, a fluid flow path through which the fluid can move is naturally formed between the heat sinks.

A predetermined space portion is formed between the stacked heat sinks, and the space portion becomes a fluid flow path.

However, the fluid flow path is divided into a first flow path 130 and a second flow path 140 which will be described later.

The laminated heat dissipation plate is formed with a welding part 110, and the welding part 110 is largely divided into an internal welding part 111 and an external welding part 112.

The internal welding part 111 is formed by welding the inflow hole 101 side of the adjacent first and second heat sinks 202 and 203.

That is, when the first heat dissipation plate 202 and the second heat dissipation plate 203 adjacent to the right side come into contact with each other, the inlet hole 101 portions of the first heat dissipation plate 202 and the second heat dissipation plate 203 are in contact with each other. The inner welding part 111 is formed by welding the inflow holes 101 to each other.

As described above, the internal welding part 111 is formed on the set of heat sinks in the form of welding the inlet holes of the first heat sink 202 and the second heat sink 203 adjacent to the right side.

The external welding part 112 is formed by welding the outer end portions of the first heat dissipation plate 202 and the second heat dissipation plate 203 to each other.

When the first heat dissipation plate 202 and the second heat dissipation plate 203 adjacent to the left side come into contact with each other, the end portions of the first heat dissipation plate 202 and the second heat dissipation plate 203 adjacent to the left side come into contact with each other and weld the end portions. The external welding portion 112 is formed on a set of heat sinks.

Here, the welding part 110 may be formed by forming an internal welding part 111 with a right side second heat dissipating plate 203 around the first heat dissipating plate 202, and an external welding part with the left part of the second heat dissipating plate 203. 112 is formed.

As described above, the heat dissipation plate group 200 includes first, second, first, second, first, second, ...., heat dissipation plates are sequentially stacked and at the same time the inner welding part 111 and the outside. Welds 112 are alternately formed.

When the welding part 110 is formed, a flow path is naturally formed between the first heat sink 202 and the second heat sink 203 which are in contact, and the flow path largely includes the first flow path 130 and the second flow path. The flow path 140 is distinguished, and the second flow path 140 is in communication with each other by the body 120 is formed.

The first flow path 130 is formed between the first heat dissipation plate 202 and the second heat dissipation plate 203 to which the outer end portion is welded.

The second flow path 112 is formed between the first heat dissipation plate 202 and the second heat dissipation plate 203 to which the inflow hole 101 is welded. Here, the first flow path 111 and the second flow path 112 are alternately formed in the heat sink group 200 that is sequentially stacked.

That is, the first, second, first, second, first, second, .... The flow path is formed by alternating intersections.

The main body 120 is formed in a shape surrounding the heat dissipation plate group 200, and is formed in a shape in close contact with the side heat dissipation plate 201, and is formed in a shape spaced apart from a circumferential surface of the heat dissipation plate group 200. do.

In addition, the heat sink is formed in an elliptical shape (oblong type), the outer welding portion 112 of the heat sink group 200 is formed of a circular curved welding portion and a linear welding portion, in the case of a linear welding portion to concentrate the internal pressure of the fluid flow path Therefore, the reinforcing part 123 for supporting the pressure of the linear welding part is separately formed in the main body 120. The reinforcement part 123 reinforces the tensile force received by the heat sink when the side pressure of the heat sink is applied, so that the thickness of the heat sink may be thin enough to withstand the pressure.

An inlet 121 is formed at one side of the main body 120 to communicate with one side inlet hole of the side heat sink 201, and an outlet 122 communicating with the other side inlet hole of the side heat sink 201 at the other side of the main body 120. ) Is formed.

The fluid introduced into the inlet 121 flows into the first flow path 130 formed first, flows between the heat sink and the heat sink, and then exits the outlet 122.

Some of the fluid introduced into the inlet 121 flows between the heat sink and the heat sink introduced into the second flow path 130 formed in the second, third, fourth, ..., and then is discharged through the outlet 122. .

Accordingly, the fluid introduced into the inlet 121 is discharged to the outside through the outlet 122 after flowing through the alternately formed first flow path 130.

Meanwhile, an inlet 124 communicating with the second flow path 140 is formed on an outer circumferential surface of the main body 120, and an outlet 125 is formed on the opposite side from the inlet 124.

The fluid flowing into the inlet 124 is the entire heat sink along the second flow path 140 formed between the first heat dissipation plate 202 and the second heat dissipation plate 203 welded to the ends of the inflow hole 101. After the flow is discharged to the outlet (125) side.

As mentioned above, the circumferential surface of the main body 120 is formed at a predetermined distance from the circumferential surface of the heat dissipation plate group so that the fluid introduced into the inlet 124 of the main body 120 is partially in communication. After flowing between the heat sink and the heat sink along the flow path 140, it is discharged to the outlet (125).

Then, a portion flows along the circumferential surface and flows along the second flow path 140, and then flows along the circumferential surface and is discharged to the outlet 125.

Herein, the fluid introduced through the inlet 124 flows along the first flow path 130 by being flowed along the second flow path 140 between the first heat sink 202 and the second heat sink 203. The heat exchange takes place between the fluid and each other.

The operation effect by the above configuration is as described later.

After forming the heat dissipation plate group 200 consisting of the first heat dissipation plate 202 and the second heat dissipation plate 203, the inside of the inlet hole 101 of the first heat dissipation plate 202 and the second heat dissipation plate 203 is welded. After forming the welding part 111 and forming an external welding part 112 in which the outer peripheral end portions of the adjacent first heat sink 202 and the second heat sink 203 are welded, an inlet 121, an outlet 122, and an inlet are formed. 124, the heat dissipation plate group 200 is installed in the main body 120 in which the outlet 125 is formed.

And the straight portion of the outer welding portion 112 of the heat sink group 200 to form a reinforcement portion 123 separately to reinforce the tensile force.

At this time, the inlet hole 101 of the heat sink is formed so as to communicate only with the inlet 121 and the outlet 122 of the body 120, the circumferential surface of the body 120 is spaced apart from the circumferential surface of the heat sink group Create a space for the fluid to flow.

After forming as described above, when the low-temperature fluid is introduced through the inlet 121, and the high-temperature fluid is introduced through the inlet 124, the low-temperature fluid flows along the first flow path 130. The high temperature fluid flows along the second flow path 140 such that the flow fluids flowing along the first flow path 130 and the second flow path 140 exchange heat with each other by surface contact. .

Then, the fluid flowing along the first flow path 130 is discharged to the outside through the outlet 122 and the fluid flowing along the second flow path 140 is discharged to the outside through the outlet 125. .

Therefore, heat exchange by surface contact occurs between the fluid flowing along the first flow path 130 and the second flow path 140 in the same manner as described above.

In this case, since the first flow path 130 and the second flow path 140 are alternately formed, even when the pressure on the first flow path 130 is high and the pressure on the second flow path 140 is low, Heat sink distortion is minimized.

In addition, the first heat dissipation plate 202 and the second heat dissipation plate 203 are spaced apart from each other, but the extension depression 102 and the extension protrusion 103 are applied to each other by the pressure applied from one side The silver is evenly distributed through the contact portion, so that the heat sink is hardly damaged by the pressure.

Therefore, the heat exchanger according to the present invention can be used for applications such as condensers, coolers, heaters, heat exchangers for heating and hot water supply, evaporators and compressors.

According to the present invention, the heat exchange effect is achieved by stacking heat sinks formed in a plate shape with each other so that two fluid movement paths through which fluids move are adjacent to each other to form a surface contact with each other. Has the effect of being improved.

In addition, there is also an effect that the pressure is distributed by mutual contact between the fluid movement path and the fluid movement path of the heat sink, and the heat sink itself is also in contact with each other so that the high pressure is equally distributed to operate at high pressure.
