Description

Technical Field

[0001] The present invention relates to the technical field of heat exchange devices, and in particular to a heat exchange device. Background Art

[0002] In a heat exchange system, the heat exchanger is the core component. It typically features a heat exchange medium circulation channel and a heat exchange liquid circulation channel, utilizing the temperature difference between the two liquids to achieve heat transfer.

Under actual operating conditions, the metal barriers are subject to prolonged thermal stress from the pressure difference between the two liquids, as well as from oil temperature fluctuations. This can lead to fatigue in the metal barriers and seal aging, resulting in perforation or seal failure in the barriers, which in turn can cause fluid interpenetration and contamination of the heat exchange medium and the liquid.

[0023] Reference Figure 1 as well as Figure 2 As shown, the heat exchange device involved in the embodiment of the present application has a first direction x, and the heat exchange device includes: a first liquid collecting member 100 and a heat exchange assembly 200.

[0024] Specifically, the heat exchange assembly 200 includes multiple safety layers 210, multiple medium layers 220, multiple heat exchange layers 230 and multiple partitions 240. The multiple medium layers 220 and the multiple heat exchange layers 230 are staggered along the first direction x, and a safety layer 210 is provided between any adjacent medium layers 220 and heat exchange layers 230, a partition 240 is provided between any adjacent safety layers 210 and medium layers 220, and a partition 240 is provided between any adjacent safety layers 210 and heat exchange layers 230. Each safety layer 210 is provided with a liquid leakage port 211, and each liquid leakage port 211 is connected to the interior of the first liquid collecting component 100.

[0025] It should be noted that the first direction x is Figure 1 The direction pointed by x.

[0026] It should be noted that in wind power generation systems, oil-immersed transformers have become key equipment in wind farm booster stations due to their high reliability and large capacity. Since wind farms are often located in remote areas with large ambient temperature fluctuations and transformers operating at full load for long periods of time, controlling the temperature of the insulating oil within them is particularly critical. When heat is dissipated from an oil-immersed transformer via a heat exchanger, temperature regulation is typically achieved through heat exchange between antifreeze and transformer oil. During this heat exchange process, the heat exchanger must withstand multiple stresses, including oil pressure fluctuations, mechanical vibrations, and sudden temperature changes. Furthermore, the solution within the heat exchanger is corrosive to the partitions, which can easily cause perforation of partition 240. If the antifreeze and transformer oil mix within dielectric layer 220 or heat exchange layer 230 due to perforation of partition 240, this can degrade the transformer's insulation performance and potentially cause a short-circuit explosion, seriously threatening the safe operation of the wind power generation system.

[0027] In the heat exchange device of the present application, the heat exchange medium flows in the medium layer 220, and the liquid to be heat exchanged flows in the heat exchange layer 230. Since the multiple medium layers 220 and the multiple heat exchange layers 230 are staggered along the first direction x, the heat of the liquid to be heat exchanged can be taken away by the heat exchange medium to achieve heat exchange of the heat exchange liquid. Since a safety layer 210 is provided between any adjacent medium layer 220 and heat exchange layer 230, and the partition 240 is provided between any adjacent safety layer 210 and medium layer 220, and a partition 240 is provided between any adjacent safety layer 210 and heat exchange layer 230, a partition 240 can be provided between any adjacent medium layer 220 and heat exchange layer 230, so that a closed liquid flow space is separated by the partition 240 for the medium layer 220 and the heat exchange layer 230, thereby achieving separation of the heat exchange medium and the liquid to be heat exchanged. At the same time, even if the partition 240 is perforated, the leaked liquid can enter the safety layer 210 between the medium layer 220 and the heat exchange layer 230, so that the possibility of different liquids interpenetrating in the medium layer 220 or the heat exchange layer 230 can be reduced. Furthermore, since each safety layer 210 is provided with a leakage port 211, each leakage port 211 is connected to the interior of the first liquid collecting member 100. In this way, the liquid leaked into the safety layer 210 can be discharged into the first liquid collecting member 100 through the leakage port 211, so as to discharge the leaked liquid out of the heat exchange component 200, further reducing the possibility of different liquids interpenetrating in the medium layer 220 or the heat exchange layer 230, thereby improving the reliability of the heat exchange device.

[0028] Reference Figure 3 as well as Figure 4 As shown, the heat exchange layer 230 is provided with a first liquid inlet 231, a heat exchange channel 232 and a first liquid outlet 233. The two ends of the heat exchange channel 232 are respectively connected to the first liquid inlet 231 and the first liquid outlet 233. The heat exchange device also includes a second liquid collecting part 300. The first liquid inlet 231 and the first liquid outlet 233 are respectively connected to the interior of a second liquid collecting part 300.

[0029] In this embodiment, the liquid to be heat exchanged can flow through one of the second liquid collecting parts 300, the first liquid inlet 231, the heat exchange channel 232, the first liquid outlet 233 and the other second liquid collecting part 300 in sequence to realize the circulation flow of the liquid to be heat exchanged, thereby improving the heat exchange efficiency of the liquid to be heat exchanged.

[0030] Reference Figure 1 As shown, the second liquid collecting piece 300 is extended along the first direction x, and the second liquid collecting piece 300 is welded to each safety layer 210, each medium layer 220, each heat exchange layer 230 and each partition 240, and one of the second liquid collecting pieces 300 is sealed outside each first liquid inlet 231, and the other second liquid collecting piece 300 is sealed outside each first liquid outlet 233.

[0031] In this embodiment, since the second liquid collecting member 300 is welded to each safety layer 210, each dielectric layer 220, each heat exchange layer 230, and each partition 240, the sealing performance of the connection between the second liquid collecting member 300 and the heat transfer component can be improved, and the possibility of the heat exchange liquid in the second liquid collecting member 300 leaking from the connection between the second liquid collecting member 300 and the heat transfer component is reduced, the loss of the heat exchange liquid is reduced, and the heat exchange liquid is reduced from flowing into the connection between the second liquid collecting member 300 and the heat transfer component. The possibility of the heat exchange liquid leaking from the first liquid inlet 231 and / or the first liquid outlet 233 is reduced, thereby further reducing the loss of the heat exchange liquid and reducing the possibility of the heat exchange liquid flowing into the dielectric layer 220 from the first liquid inlet 231 and / or the first liquid outlet 233.

[0032] Reference Figure 2 as well as Figure 4 As shown, the heat exchange device also has a second direction y and a third direction z, and the first direction x, the second direction y and the third direction z are perpendicular to each other. The heat exchange layer 230 has a first fin portion 234, a first seal portion 235 and a second seal portion 236; the first fin portion 234 is provided with a heat exchange channel 232 extending along the second direction y, the first seal portion 235 and the second seal portion 236 are respectively connected to the two ends of the first fin portion 234 along the third direction z, and the first liquid inlet 231 and the first liquid outlet 233 are both located between the first seal portion 235 and the second seal portion 236; wherein the first seal portion 235 and / or the second seal portion 236 are provided with a first liquid leakage groove 237, and the first liquid leakage groove 237 is used to communicate with the outside world.

[0033] It should be noted that the second direction y is Figure 1 The direction y points to, and the third direction z is Figure 1 The direction indicated by z.

[0034] In this embodiment, the first sealing portion 235 and the second sealing portion 236 can be used to seal the two ends of the first fin portion 234 along the third direction z, so as to reduce the possibility of leakage of the liquid to be heat exchanged from the two ends of the first fin portion 234 along the third direction z, thereby improving the reliability of the heat exchange channel 232 at the edges of the two ends of the first fin portion 234 along the third direction z. At the same time, the liquid to be heat exchanged can flow into the heat exchange channel 232 from the first liquid inlet 231 between the first sealing portion 235 and the second sealing portion 236, and flow out of the heat exchange channel 232 through the first liquid outlet 233 between the first sealing portion 235 and the second sealing portion 236, so as to reduce the interference of the first sealing portion 235 and the second sealing portion 236 with the liquid to be heat exchanged flowing through the first liquid inlet 231 and the first liquid outlet 233. Furthermore, since one of the second liquid collecting pieces 300 is sealed outside each first liquid inlet 231, and the other second liquid collecting piece 300 is sealed outside each first liquid outlet 233, when the second liquid collecting piece 300 is welded to the heat transfer assembly, the second liquid collecting piece 300 will be welded to the first sealing portion 235 and / or the second sealing portion 236 at both ends along the second direction y. If the second liquid collecting piece 300 is welded to the first sealing portion 235 at both ends along the second direction y, the first sealing portion 235 is provided with a first liquid leakage groove 237. When the second liquid collecting piece 300 is welded to the first sealing portion 235 at both ends along the second direction y, the first liquid leakage groove 237 is formed. When welding to both ends of y, the first sealing portion 235 and the adjacent partition 240 will be deformed due to the welding effect, so that a leakage gap will be generated between the first sealing portion 235 and the adjacent partition 240. The liquid to be heat exchanged may leak out of the heat exchange layer 230 from the leakage gap. At this time, the liquid to be heat exchanged at the leakage gap can be guided through the first leakage groove 237, so that the liquid to be heat exchanged at the leakage gap can flow to the outside under the guiding effect of the first leakage groove 237, thereby reducing the risk of the liquid to be heat exchanged at the leakage gap flowing to the dielectric layer 220. Similarly, if the second liquid collecting member 300 is welded to the second sealing portion 236 at both ends along the second direction y, the second sealing portion 236 is provided with a first leakage groove 237. When the second liquid collecting member 300 is welded to the second sealing portion 236 at both ends along the second direction y, the second sealing portion 236 and the adjacent partition 240 will be deformed due to the welding effect. In this way, a leakage gap will be generated between the second sealing portion 236 and the adjacent partition 240. The heat exchange liquid may leak out of the heat exchange layer 230 from the leakage gap. At this time, the first leakage groove 237 can be used to guide the heat exchange liquid at the leakage gap, so that the heat exchange liquid at the leakage gap can flow to the outside under the guiding effect of the first leakage groove 237, thereby reducing the risk of the heat exchange liquid at the leakage gap flowing to the dielectric layer 220.Similarly, if the second liquid collecting member 300 is welded to both ends of the first sealing portion 235 and the second sealing portion 236 along the second direction y, the first sealing portion 235 and the second sealing portion 236 are both provided with the first liquid leakage groove 237 .

[0035] Reference Figure 5 as well as Figure 6 As shown, the medium layer 220 is provided with a second liquid inlet 221, a medium flow channel 222 and a second liquid outlet 223. The second liquid inlet 221 and the second liquid outlet 223 are both spaced apart from the second liquid collecting member 300. The two ends of the medium flow channel 222 are respectively connected to the second liquid inlet 221 and the second liquid outlet 223. The heat exchange device also includes a third liquid collecting member 400. The second liquid inlet 221 and the second liquid outlet 223 are respectively connected to the interior of a third liquid collecting member 400.

[0036] In this embodiment, since the second liquid inlet 221 and the second liquid outlet 223 are spaced apart from the second liquid collecting member 300, the possibility of the liquid to be heat exchanged entering the medium layer 220 through the second liquid inlet 221 and the second liquid outlet 223 is reduced. At the same time, the heat exchange medium can flow sequentially through one of the third liquid collecting members 400, the second liquid inlet 221, the medium flow channel 222, the second liquid outlet 223, and the other third liquid collecting member 400, thereby achieving a circulating flow of the heat exchange medium and improving the heat exchange efficiency of the liquid to be heat exchanged.

[0037] Reference Figure 1 As shown, the third liquid collecting piece 400 is extended along the first direction x, and the third liquid collecting piece 400 is welded to each safety layer 210, each medium layer 220, each heat exchange layer 230 and each partition 240, and one of the third liquid collecting pieces 400 is sealed outside each second liquid inlet 221, and the other third liquid collecting piece 400 is sealed outside each second liquid outlet 223.

[0038] In this embodiment, since the third liquid collecting member 400 is welded to each safety layer 210, each medium layer 220, each heat exchange layer 230, and each partition 240, the sealing performance of the connection between the third liquid collecting member 400 and the heat transfer component can be improved, and the possibility of the heat exchange medium in the third liquid collecting member 400 leaking from the connection between the third liquid collecting member 400 and the heat transfer component is reduced, the loss of the heat exchange medium is reduced, and the heat exchange medium is reduced from flowing into the connection between the third liquid collecting member 400 and the heat transfer component. The possibility of the heat exchange medium leaking from the second liquid inlet 221 and / or the second liquid outlet 223 can be reduced, thereby further reducing the loss of the heat exchange medium and reducing the possibility of the heat exchange medium flowing into the heat exchange layer 230 from the second liquid inlet 221 and / or the second liquid outlet 223.

[0039] Reference Figure 2 as well as Figure 6 As shown, the dielectric layer 220 has a second fin portion 224, a third sealing portion 225 and a fourth sealing portion 226; the second fin portion 224 is provided with a dielectric flow channel 222, and both ends of the second fin portion 224 along the third direction z are connected to the third sealing portion 225, and both ends of the second fin portion 224 along the second direction y are connected to the fourth sealing portion 226, any third sealing portion 225 is spaced apart from one of the fourth sealing portions 226 to define a second liquid inlet 221, and any third sealing portion 225 is spaced apart from another fourth sealing portion 226 to define a second liquid outlet 223; wherein, each fourth sealing portion 226 is provided with a second liquid leakage groove 227, and the second liquid leakage groove 227 is used to communicate with the outside.

[0040] In this embodiment, since both ends of the second fin portion 224 along the third direction z are connected to the third sealing portion 225, and both ends of the second fin portion 224 along the second direction y are connected to the fourth sealing portion 226, the third sealing portion 225 can be used to seal both ends of the second fin portion 224 along the third direction z, and the fourth sealing portion 226 can be used to seal both ends of the second fin portion 224 along the second direction y, so as to reduce the possibility of heat exchange medium leaking from both ends of the second fin portion 224 along the third direction z and the second direction y, thereby improving the reliability of the medium flow channel 222 at the edges of the second fin portion 224 along the third direction z and the second direction y. Furthermore, since any one of the third sealing strips 225 is spaced apart from one of the fourth sealing strips 226 to define the second liquid inlet 221, and any one of the third sealing strips 225 is spaced apart from another fourth sealing strip 226 to define the second liquid outlet 223, the third sealing strip 225 and the fourth sealing strip 226 can be prevented from interfering with the circulation of the heat exchange medium in the medium flow channel 222. Furthermore, since one of the third liquid collecting parts 400 is sealed outside each second liquid inlet 221, and another third liquid collecting part 400 is sealed outside each second liquid outlet 223, when the third liquid collecting parts 400 are welded to the heat transfer assembly, one of the third liquid collecting parts 400 will be welded to one of the fourth sealing strips 226 at one end along the third direction z, and the other third liquid collecting part 400 will be welded to another of the fourth sealing strips 226 at one end along the third direction z. At this time, the fourth sealing strip 226 and the sealing strips therewith are welded together. The adjacent partitions 240 will undergo certain deformation due to the welding effect, so that a leakage gap will be generated between the fourth sealing portion 226 and the adjacent partition 240. The heat exchange medium may leak out of the medium layer 220 from the leakage gap. At this time, the heat exchange medium at the leakage gap can be guided through the second leakage groove 227 so that the heat exchange medium at the leakage gap can flow to the outside under the guidance of the second leakage groove 227, thereby reducing the risk of the heat exchange medium at the leakage gap flowing to the heat exchange layer 230.

[0041] Reference Figure 1 as well as Figure 7 As shown, the first liquid collecting member 100 extends along the first direction x. The first liquid collecting member 100 is welded to each safety layer 210 , each medium layer 220 , each heat exchange layer 230 and each partition 240 , and is sealed outside each leakage port 211 .

[0042] In this embodiment, since the first liquid collecting piece 100 is welded to each safety layer 210, each dielectric layer 220, each heat exchange layer 230, and each partition 240, the sealing performance of the connection between the first liquid collecting piece 100 and the heat transfer component can be improved, thereby reducing the possibility of leaked liquid in the first liquid collecting piece 100 leaking from the connection between the first liquid collecting piece 100 and the heat transfer component, and reducing the possibility of leaked liquid entering the dielectric layer 220 and the heat exchange layer 230. In addition, since the first liquid collecting piece 100 is sealed on the outside of each leakage port 211, the possibility of leaked liquid leaking to the outside from the leakage port 211 can be reduced, thereby further reducing the possibility of leaked liquid flowing into the dielectric layer 220 and the heat exchange layer 230.

[0043] Reference Figure 2 as well as Figure 8 As shown, the heat exchange device also has a second direction y and a third direction z, and the first direction x, the second direction y and the third direction z are perpendicular to each other. The safety layer 210 has a third fin portion 212, a fifth sealing portion 213 and a sixth sealing portion 214; the third fin portion 212 is provided with a safety flow channel 215, and both ends of the third fin portion 212 along the third direction z are connected to the fifth sealing portion 213, and both ends of the third fin portion 212 along the second direction y are connected to the sixth sealing portion 214; wherein, at least one fifth sealing portion 213 is provided with a leakage port 211, and the fifth sealing portion 213 and / or the sixth sealing portion 214 are provided with a third leakage groove 216, and the third leakage groove 216 is used to communicate with the outside world.

[0044] Specifically, in the second direction y, the side walls of the safety layer 210 and the side walls of the adjacent partition 240 will be deformed due to the welding of the second liquid collecting member 300. In the third direction z, the side walls of the safety layer 210 and the side walls of the adjacent partition 240 will be deformed due to the welding of the third liquid collecting member 400. In this way, a leakage gap will be formed between the safety layer 210 and the adjacent partition 240, and the liquid in the safety layer 210 may leak out of the safety layer 210 through the leakage gap. In some embodiments, the two fifth sealing strips 213 are located between the two sixth sealing strips 214, and the two ends of each fifth sealing strip 213 along the second direction y are respectively against the two sixth sealing strips 214, and the two ends of the sixth sealing strip 214 are connected to the outside world, so that the sixth sealing strip 214 can be sealed. A third liquid leakage groove 216 extending along the third direction z is provided on the portion 214 to guide the liquid at the leakage gap through the third liquid leakage groove 216, so that the liquid at the leakage gap can flow to the outside under the guiding effect of the third liquid leakage groove 216, thereby reducing the risk of the liquid at the leakage gap flowing to the dielectric layer 220 and the heat exchange layer 230; in other embodiments, the two sixth sealing strip portions 214 are both located between the two fifth sealing strip portions 213, and the two ends of each sixth sealing strip portion 214 along the second direction y are respectively abutted against the two fifth sealing strip portions 213, and the two ends of the fifth sealing strip portion 213 are connected to the outside, then a third liquid leakage groove 216 extending along the second direction y can be provided on the fifth sealing strip portion 213 to guide the liquid at the leakage gap through the third liquid leakage groove 216.

[0045] In this embodiment, the third fin portion 212 can improve the heat transfer effect between the medium layer 220 and the heat exchange layer 230, so that the heat exchange medium in the medium layer 220 can take away the heat of the liquid to be heat exchanged in the heat exchange layer 230 more quickly. At the same time, if the heat exchange medium or the liquid to be heat exchanged leaks into the safety layer 210, the safety flow channel 215 of the third fin portion 212 can guide the leaked liquid so that the leaked liquid can flow to the leakage port 211, thereby discharging the leaked liquid from the heat transfer component. Furthermore, since both ends of the third fin portion 212 along the third direction z are connected to the fifth sealing portion 213, and both ends of the third fin portion 212 along the second direction y are connected to the sixth sealing portion 214, the fifth sealing portion 213 can be used to seal both ends of the third fin portion 212 along the third direction z, and the sixth sealing portion 214 can be used to seal both ends of the third fin portion 212 along the second direction y, so as to reduce the possibility of leakage of liquid from both ends of the third fin portion 212 along the third direction z and the second direction y, thereby improving the reliability of the safety flow channel 215 at the edges of the third fin portion 212 along the third direction z and the second direction y.

[0046] Reference Figure 1 as well as Figure 2 As shown, the heat exchange device also includes two fixed plates 500, which are arranged at intervals along the first direction x, and multiple safety layers 210, multiple medium layers 220, multiple heat exchange layers 230 and multiple partitions 240 are all arranged between the two fixed plates 500, so that the multiple safety layers 210, multiple medium layers 220, multiple heat exchange layers 230 and multiple partitions 240 are fixed by the two fixed plates 500, thereby improving the connection stability between the multiple safety layers 210, multiple medium layers 220, multiple heat exchange layers 230 and multiple partitions 240. At the same time, each fixed plate 500 is arranged adjacent to a safety layer 210 to prevent the heat exchange medium or the liquid to be heat exchanged from directly leaking onto the fixed plate 500, reducing the possibility of the heat exchange medium or the liquid to be heat exchanged leaking through the fixed plate 500, and further improving the reliability of the heat exchange device.

[0047] Specifically, the heat exchange device further includes a liquid level sensor, which is disposed in the first liquid collecting member 100 .

[0048] In this embodiment, the liquid in the first liquid collecting part 100 can be monitored in real time by a liquid level sensor. When the liquid height in the first liquid collecting part 100 exceeds a preset height, the liquid level sensor can transmit a liquid level signal to the system to avoid overflow or backflow of the liquid in the first liquid collecting part 100, thereby further improving the safety of the heat exchange device.
