Description

Technical Field

[0001] The present invention relates to a heat exchange system, and particularly to a heat exchange system equipped with a gas-liquid separator. Background Art

[0002] In a refrigerating refrigerant cycle, a gaseous refrigerant is pressurized by a compressor to become a high-pressure gaseous refrigerant and sent to a condenser for heat dissipation and condensation into a liquid refrigerant, then sent to an expansion valve for pressure reduction, further sent to an evaporator for heat absorption to become a gaseous refrigerant, and then the gaseous refrigerant is sent to the compressor for pressurization.

[0003] Generally, a heat exchanger is used as a condenser. Currently, the heat exchanger usually increases the heat dissipation surface area through sufficient space or volume, so that the high-pressure gaseous refrigerant can be fully dissipated and condensed into a liquid refrigerant. However, currently, the design space of electrical products is limited, so there is a need for a heat exchanger that takes into account both sufficient heat dissipation and limited space. Summary of the Invention

[0004] In view of the above problems, the present invention aims to provide a heat exchange system that can meet the requirements of both sufficient heat dissipation and limited space.

[0005] An embodiment of the present invention provides a heat exchange system, which includes a first heat exchanger, a gas-liquid separator, and a second heat exchanger. The first heat exchanger has at least one first heat exchange outlet configured to allow a working fluid in a gas-liquid mixture that has undergone heat exchange through the first heat exchanger to flow out. The gas-liquid separator has at least one gas-liquid mixture inlet, at least one gas outlet, and a liquid outlet that are connected to each other. The gas-liquid mixture inlet corresponds to and is connected to the first heat exchange outlet, and is configured to receive the gas-liquid mixed working fluid. The gas outlet is configured to allow the gaseous working fluid separated by the gas-liquid separator to flow out. The liquid outlet is configured to allow the liquid working fluid separated by the gas-liquid separator to flow out. The second heat exchanger has at least one second heat exchange inlet that corresponds to and is connected to the gas outlet and is configured to receive the gaseous working fluid.

[0006] An embodiment of the present invention provides a gas-liquid separator, which includes a body. The body has at least one gas-liquid mixture inlet, at least one gas outlet, and a liquid outlet that are connected to each other. The gas-liquid mixture inlet is configured to receive the gas-liquid mixed working fluid. The gas outlet is configured to allow the gaseous working fluid separated by the gas-liquid separator to flow out. The liquid outlet is configured to allow the liquid working fluid separated by the gas-liquid separator to flow out.

[0007] According to the heat exchange system and the gas-liquid separator of an embodiment of the present invention, by splitting into multiple heat exchangers, they can be flexibly arranged in a limited space. Moreover, by arranging a gas-liquid separator between the multiple heat exchangers, the gaseous working fluid can be fully dissipated and condensed into a liquid working fluid.

[0080] Please refer to Figures 1 to 6 。 Figure 1 A three - dimensional schematic diagram of a heat exchange system according to an embodiment of the present invention is shown. Figure 2 Shown Figure 1 A three - dimensional exploded schematic diagram of the heat exchange system. Figure 3 Shown Figure 1 A right - hand side view schematic diagram of the heat exchange system. Figure 4 Shown Figure 1 A side - view cross - section schematic diagram near the gas - liquid separator of the heat exchange system. Figure 5 Shown Figure 1 A three - dimensional exploded schematic diagram of the heat exchange system during operation. Figure 6 Shown Figure 1 A simulation schematic diagram of the gas - liquid separator of the heat exchange system during operation. In this embodiment, the heat exchange system 1 can be used as a condenser in a refrigeration refrigerant cycle. The heat exchange system 1 can be used to receive gaseous refrigerant from a compressor, condense the refrigerant into a liquid state, and then transfer the liquid refrigerant to an expansion valve.

[0081] As Figure 1 shown, the heat exchange system 1 includes a first heat exchanger 11, a second heat exchanger 12, a gas - liquid separator 13, a manifold tee 14, a first connecting pipe 15, and a second connecting pipe 16. The gas - liquid separator 13 is disposed between the first heat exchanger 11 and the second heat exchanger 12.

[0082] As Figure 2 shown, the first heat exchanger 11 has a first heat exchange inlet 11a and a first heat exchange outlet 11b. The second heat exchanger 12 has a second heat exchange inlet 12a and a second heat exchange outlet 12b. The first heat exchange outlet 11b is configured to allow the gas-liquid mixed working fluid that has undergone heat exchange in the first heat exchanger 11 to flow out. In this embodiment, the forms of the first heat exchanger 11 and the second heat exchanger 12 are not limited, and can be, for example, microchannel heat exchangers. The materials of the first heat exchanger 11 and the second heat exchanger 12 can be aluminum, copper, but are not limited thereto, and can also be other materials that are easy to dissipate heat.

[0083] The gas-liquid separator 13 has a gas-liquid mixing inlet 13a, a gas outlet 13b, and a liquid outlet 13c. The liquid outlet 13c faces a gravity direction G (opening downward with the gas-liquid separator 13 as the center). The gas outlet 13b faces an anti-gravity direction UG opposite to the gravity direction G (opening upward with the gas-liquid separator 13 as the center). The gas-liquid mixing inlet 13a is configured to receive the gas-liquid mixed working fluid. The gas outlet 13b is configured to allow the gaseous working fluid separated by the gas-liquid separator 13 to flow out. The liquid outlet 13c is configured to allow the liquid working fluid separated by the gas-liquid separator 13 to flow out.

[0084] The first heat exchange inlet 11a is used to receive the gaseous working fluid. The gas-liquid mixing inlet 13a is correspondingly connected and communicated with the first heat exchange outlet 11b of the first heat exchanger 11, and is configured to receive the gas-liquid mixed working fluid. The second heat exchange inlet 12a of the second heat exchanger 12 is correspondingly connected and communicated with the gas outlet 13b via the first connecting pipe 15, and is configured to receive the gaseous working fluid. The second heat exchange outlet 12b is connected and communicated with the manifold tee 14, and is configured to allow the liquid working fluid that has undergone heat exchange in the second heat exchanger 12 to flow out. The liquid outlet 13c is connected and communicated with the manifold tee 14 via the second connecting pipe 16. The manifold tee 14 is used to discharge the liquid working fluid from the heat exchange system 1.

[0085] As Figure 3 shown, the horizontal height relationship of the openings of each component is described. The first heat exchange inlet 11a is higher than the second heat exchange inlet 12a. The second heat exchange inlet 12a is higher than the gas outlet 13b. The gas outlet 13b is higher than the gas-liquid mixing inlet 13a. The gas-liquid mixing inlet 13a is substantially at the same height as the first heat exchange outlet 11b. The first heat exchange outlet 11b is higher than the liquid outlet 13c. The liquid outlet 13c is higher than the second heat exchange outlet 12b. Through this horizontal height relationship, the flow of the working fluid can be assisted by gravity, and the energy consumption required for transporting the working fluid can be saved.

[0086] In this embodiment, the first heat exchanger 11, the second heat exchanger 12, the gas-liquid separator 13, the manifold tee 14, the first connecting pipe 15 and the second connecting pipe 16 can be disassembled from each other as shown in Figure 2 . Therefore, it is convenient to transport the heat exchange system 1. In addition, various types of the first heat exchanger 11 and the second heat exchanger 12 can be assembled and matched at will. In this embodiment, the included angle between the first heat exchanger 11 and the second heat exchanger 12 can be 90 degrees perpendicular, but not limited thereto. In other embodiments, the included angle between the first heat exchanger 11 and the second heat exchanger 12 can be less than 180 degrees. Thereby, the heat exchange system 1 can be flexibly arranged in an environment with a special angle.

[0087] In this embodiment, as shown in Figure 4 , the details of the gas-liquid separator 13 in this embodiment are described. The gas-liquid separator 13 includes a body 131 and a gas-permeable perforated partition 132. The body 131 is a T-shaped pipe. The body 131 has a separation chamber 130. The separation chamber 130 has a gas-liquid mixture inlet 13a, a gas outlet 13b and a liquid outlet 13c. The gas-liquid mixture inlet 13a and the first heat exchanger 11 can be connected through methods such as screwing and welding. The gas outlet 13b is connected to the first connecting pipe 15. The liquid outlet 13c faces the gravity direction G. The gas outlet 13b faces the anti-gravity direction UG. The gas-liquid mixture inlet 13a faces a horizontal direction H. In this embodiment, the body 131 is a T-shaped pipe, but not limited thereto. In other embodiments, the body 131 can also be a Y-shaped pipe or other shaped tee pipes, and regarding the configuration relationship among the gas-liquid mixture inlet 13a, the gas outlet 13b and the liquid outlet 13c, the gas outlet 13b is higher than the gas-liquid mixture inlet 13a, and the gas-liquid mixture inlet 13a is higher than the liquid outlet 13c.

[0088] The gas-permeable perforated partition 132 is arranged in the body 131 and is relatively below the gas outlet 13b in the gravity direction G. The through-sectional area of the gas-permeable perforated partition 132 is smaller than the cross-sectional area of the gas outlet 13b. Specifically, the gas-permeable perforated partition 132 has a through-hole 132a. The cross-sectional area of the through-hole 132a is smaller than the cross-sectional area of the gas outlet 13b. In this embodiment, the number of the through-holes 132a is one, the through-hole 132a is located at the center of the gas-permeable perforated partition 132, and the shape of the through-hole 132a is circular, but not limited thereto. In other embodiments, the number of the through-holes can also be multiple, the position of the through-holes can also be at the edge or not limited, and the shape of the through-holes can also be polygonal, grid-shaped or not limited.

[0089] As shown in Figure 5 , the operation of the heat exchange system 1 is described. In Figure 5In the figure, the gaseous working fluid is represented by a dashed arrow, the liquid working fluid is represented by a solid arrow, and the gas-liquid mixed working fluid is represented by a hollow arrow. The gaseous working fluid enters the first heat exchanger 11 from the first heat exchange inlet 11a. Through the heat exchange of the first heat exchanger 11, the gas-liquid mixed working fluid flows out from the first heat exchange outlet 11b. The gas-liquid mixed working fluid enters the gas-liquid separator 13 from the gas-liquid mixed inlet 13a. By separating the gaseous working fluid and the liquid working fluid through the gas-liquid separator 13, the gaseous working fluid flows out from the gas outlet 13b, and the liquid working fluid flows out from the liquid outlet 13c.

[0090] The gaseous working fluid flowing out from the gas outlet 13b flows through the first connecting pipe 15 to the second heat exchange inlet 12a, and enters the second heat exchanger 12 from the second heat exchange inlet 12a. Through the heat exchange of the second heat exchanger 12, the liquid working fluid flows out from the second heat exchange outlet 12b. The liquid working fluid flowing out from the liquid outlet 13c enters the manifold tee 14 through the second connecting pipe 16, and the liquid working fluid flowing out from the second heat exchange outlet 12b also enters the manifold tee 14. The liquid working fluid is discharged from the heat exchange system 1 through the manifold tee 14.

[0091] In addition, in other embodiments, the number of the second heat exchangers 12 can be multiple, and the number of the gas-liquid separators 13 can also be multiple. By series connection or parallel connection, more than three heat exchangers can be flexibly arranged in a limited space.

[0092] As Figure 6 shown, the simulation results of the gas-liquid separator 13 when the heat exchange system 1 is operating are illustrated. In Figure 6 , the darker the color, the lower the temperature and it belongs to the liquid working fluid, and the lighter the color, the higher the temperature and it belongs to the gaseous working fluid. In this embodiment, due to the blockage of the gas-permeable perforated partition 132 ( Figure 4 ) and the action of the gravity in the direction of gravity G, the gaseous working fluid can flow out from the gas outlet 13b, and the liquid working fluid can flow out from the liquid outlet 13c. However, it can be found that part of the liquid working fluid FL stays near the gas outlet 13b, and part of the gaseous working fluid FG stays near the liquid outlet 13c.

[0093] Please refer to Figures 7 to 8 . Figure 7 The side sectional schematic view of the gas-liquid separator according to another embodiment of the present invention is shown. Figure 8 Shown is Figure 7 the simulation schematic diagram of the gas-liquid separator when it is operating.

[0094] The gas-liquid separator 23 includes a main body 231 and a gas-permeable perforated partition 232. The main body 231 generally has the shape of a T-shaped pipe or a Y-shaped pipe. The main body 231 has a separation chamber 230. The separation chamber 230 has a gas-liquid mixture inlet 23a, a gas outlet 23b, and a liquid outlet 23c. The gas-liquid mixture inlet 23a is communicated with the first heat exchanger 21. The gas outlet 23b is communicated with the first connecting pipe 25. The liquid outlet 23c is communicated with the second connecting pipe 26. The gas-permeable perforated partition 232 having a through hole 232a is disposed at the gas outlet 23b. The first heat exchanger 21 is the same as the first heat exchanger 11 of Figure 1 and will not be described in detail. The first connecting pipe 25 is the same as the first connecting pipe 15 of Figure 1 and will not be described in detail.

[0095] In this embodiment, the inner diameter D1 of a pipe portion 231a of the main body 231 near the liquid outlet 23c is larger than the inner diameter D2 of the liquid outlet 23c. The liquid outlet 23c is arranged to correspond to the flowing direction of the liquid working fluid. In this embodiment, the liquid outlet 23c is eccentric with respect to the pipe portion 231a in a manner away from the gas-liquid mixture inlet 23a. The size of the second connecting pipe 26 matches the inner diameter D2 of the liquid outlet 23c. In addition, in this embodiment, the internal space of the pipe portion 231a is cylindrical, but it is not limited thereto. In other embodiments, the pipe portion 231a may also be a tapered and eccentric funnel shape, or not limited to other shapes.

[0096] As Figure 8 shown, the simulation results of the gas-liquid separator 23 are described. In this embodiment, due to the blockage of the gas-permeable perforated partition 232 ( Figure 7 ), the eccentric setting of the liquid outlet 23c ( Figure 7 ), and the action of the gravity in the direction of gravity G, the gaseous working fluid can flow out from the gas outlet 23b, and the liquid working fluid can flow out from the liquid outlet 23c. Moreover, there is no situation where the liquid working fluid stays near the gas outlet 23b, nor is there a situation where the gaseous working fluid stays near the liquid outlet 23c.

The first manifold long tube 312 is a long tube with both ends closed. The first manifold long tube 312 has a total heat exchange inlet 30a and a total heat exchange outlet 30b. In terms of the horizontal height, the total heat exchange inlet 30a is higher than the total heat exchange outlet 30b. The total heat exchange inlet 30a is used to receive a gaseous working fluid. The total heat exchange outlet 30b is used to discharge the liquid working fluid from the heat exchange system 3. Each of the first tube bodies 3111, 3112, 3113, 3114 is a flat tube. The plurality of first tube bodies 3111, 3112, 3113, 3114 are arranged in parallel along the gravity direction G.

Each of the first fins 313 is disposed between adjacent first tube bodies 3111, 3112, 3113, 3114. The first fins 313 are used for heat conduction with the first tube bodies 3111, 3112, 3113, 3114, but not limited thereto. In other embodiments, the first fins may also be omitted.

[0101] The second heat exchanger 32 includes a plurality of second tube bodies 3211, 3212, 3213, 3214, a second manifold long tube 322, and a plurality of second fins 323.

The second fins 323 are used for heat conduction with the second tube bodies 3211, 3212, 3213, 3214, but not limited thereto. In other embodiments, the second fins may also be omitted.

[0102] As Figure 10 and Figure 11As shown, the gas-liquid separator 33 includes a body 331, three connected non-porous partitions 332, a connected non-porous partition 333, a separating porous partition 334, a separating porous partition 335, a first separating porous partition 336, a separating porous partition 337, and a second separating porous partition 338. The body 331 is a long tube with both ends closed. The body 331 has four connected chambers 330a arranged along the gravity direction G, three separating chambers 330b, 330c, 330d, two separating chambers 330e, 330f, and a collecting chamber 330g.

[0103] The three connected non-porous partitions 332 separate the four connected chambers 330a. Each connected non-porous partition 332 is between adjacent connected chambers 330a. The connected non-porous partition 333 separates the connected chamber 330a and the separating chamber 330b. The connected non-porous partition 333 is between the connected chamber 330a and the separating chamber 330b. Each connected chamber 330a has a connected inlet 330a1 and a connected outlet 330a2. The connected inlet 330a1 is for the first pipe body 3111 to be inserted, so that the connected inlet 330a1 is connected to the first heat exchanger 31( Figure 9 ) is connected. The connected outlet 330a2 is for the second pipe body 3211 to be inserted, so that the connected outlet 330a2 is connected to the second heat exchanger 32( Figure 9 ) is connected. The connected non-porous partitions 332, 333 can increase the circulation time of the gaseous working fluid in the first pipe body 3111 and the second pipe body 3211 to effectively conduct heat exchange.

[0104] The separating porous partition 334 and the separating porous partition 335 separate the three separating chambers 330b, 330c, 330d.

[0116] As Figure 13 shown, the operation of the heat exchange system 3 is described. In Figure 13 , the gaseous working fluid is represented by a dashed arrow, the liquid working fluid is represented by a solid arrow, and the gas-liquid mixed working fluid is represented by a hollow arrow. The gaseous working fluid enters the first manifold long tube 312 of the first heat exchanger 31 from the total heat exchange inlet 30a, and then enters the four first tube bodies 3111 above the manifold non-perforated partition plate 314. The gaseous working fluid respectively enters the four second tube bodies 3211 of the second heat exchanger 32 through the four communication chambers 330a of the gas-liquid separator 33. The gaseous working fluid exchanges heat in the first tube body 3111 and the second tube body 3211, and condenses into a gas-liquid mixed working fluid.

[0117] Among the gas-liquid mixed working fluid above the second manifold perforated partition plate 324, a part of the gaseous working fluid enters the three second tube bodies 3212 above the second manifold perforated partition plate 324, and a part of the liquid working fluid penetrates through the second manifold perforated partition plate 324 and enters below the second manifold perforated partition plate 324. The gaseous working fluid exchanges heat in the second tube body 3212, and condenses into a gas-liquid mixed working fluid, and enters the separation chambers 330b, 330c, and 330d respectively.

[0118] After the gas-liquid mixed working fluid enters the separation chamber 330b, a part of the gaseous working fluid enters the first tube body 3112, and a part of the liquid working fluid enters the separation chamber 330c. After the liquid working fluid and the gas-liquid mixed working fluid enter the separation chamber 330c, a part of the gaseous working fluid enters the first tube body 3112, and the remaining part of the liquid working fluid enters the separation chamber 330d. After the liquid working fluid and the gas-liquid mixed working fluid enter the separation chamber 330d, a part of the gaseous working fluid enters the first tube body 3112, and the remaining part of the liquid working fluid enters the separation chamber 330e.

[0119] The gaseous working fluid enters the three first pipe bodies 3112. The gaseous working fluid undergoes heat exchange in the first pipe bodies 3112 and condenses into a gas-liquid mixed working fluid. Among the gas-liquid mixed working fluid below the collector non-porous partition 314 and above the first collector porous partition 315, a part of the gaseous working fluid enters the two first pipe bodies 3113 above the first collector porous partition 315, and a part of the liquid working fluid penetrates the first collector porous partition 315 and enters below the first collector porous partition 315. The gaseous working fluid undergoes heat exchange in the first pipe bodies 3113 and condenses into a gas-liquid mixed working fluid, and enters the separation chambers 330e and 330f respectively.

[0120] After the gas-liquid mixed working fluid enters the separation chamber 330e, a part of the gaseous working fluid enters the second pipe body 3213, and a part of the liquid working fluid enters the separation chamber 330f. After the liquid working fluid and the gas-liquid mixed working fluid enter the separation chamber 330f, a part of the gaseous working fluid enters the second pipe body 3213, and the remaining part of the liquid working fluid enters the collector chamber 330g.

[0121] The gaseous working fluid enters the two second pipe bodies 3213. The gaseous working fluid undergoes heat exchange in the second pipe bodies 3213 and condenses into a gas-liquid mixed working fluid. Among the liquid working fluid and the gas-liquid mixed working fluid below the second collector porous partition 324, a gas-liquid mixed working fluid with a higher proportion of liquid working fluid is mixed and enters the lowermost second pipe body 3214. The gas-liquid mixed working fluid undergoes heat exchange in the second pipe body 3214 and condenses into a liquid working fluid, which enters the collector chamber 330g. The liquid working fluid enters the lowermost first pipe body 3114 and then enters below the first collector porous partition 315 in the first collector long pipe 312. The liquid working fluid is discharged from the heat exchange system 3 through the total heat exchange outlet 30b.

[0122] The configuration quantities and aperture sizes of various separation porous partitions 334, 335, 336, 337, 338 can be adjusted according to design requirements for gas-liquid separation, and the aperture can be designed corresponding to the condensation effect.

[0123] In addition, in other embodiments, the number of the second heat exchangers 32 can be multiple, and the number of the gas-liquid separators 33 can also be multiple. Through series connection or parallel connection, more than three heat exchangers can be flexibly arranged in a limited space. For example, the gas-liquid separator 33 can be used to replace the collector long pipe. In addition, Figure 1 the embodiments of Figure 9 as long as there is no contradiction, can also be used in combination.

[0124] In summary, the heat exchange system and the gas-liquid separator disclosed by the present invention can be flexibly arranged in a limited space by being split into multiple heat exchangers. Moreover, by arranging a gas-liquid separator between the multiple heat exchangers, the gaseous working fluid can be fully cooled and condensed into a liquid working fluid.
