Description

Technical Field

[0001] The present application relates to the technical field of heat pipe heat exchangers, and in particular to a heat exchange device, an inverter cooling system and a converter cooling system. Background Art

[0002] In devices such as inverters and converters, it is necessary to cool the power components inside the equipment (including but not limited to IGBT modules, chips, and motors, etc.). At present, the heat exchanger with the best heat exchange effect is the heat pipe heat exchanger, which mostly adopts a ring loop. Specifically, in the heat pipe heat exchanger, the working fluid in the evaporation section is heated and vaporized, and the working fluid vapor is transported to the condensation section through several pipes. After being cooled, it is condensed into liquid working fluid and flows back to the evaporation section through the return pipe. The whole cycle constitutes a ring loop.

[0003] At present, the problem with heat pipe heat exchangers is that, usually, the evaporation section and the condensation section are arranged in the same plane. If the steam pipe and the return pipe are located outside the above plane, the heat pipe heat exchanger will occupy a large space, resulting in the layout of the heat pipe heat exchanger being not compact enough. On the contrary, if the steam pipe and the return pipe are located in the above plane and arranged between the evaporation section and the condensation section, the rising steam of the evaporation section and the condensation liquid returning from the condensation section will interfere with each other, affecting the heat exchange efficiency of the heat pipe heat exchanger. Utility Model Content

[0004] Based on this, it is necessary to provide a heat exchange device, an inverter cooling system and a converter cooling system to solve the problem that the existing heat pipe heat exchanger cannot reduce its own volume while ensuring its own heat exchange efficiency.

[0005] The heat exchange device provided by the present application includes a shell, an air collecting hood and an air outlet pipe, an evaporation chamber is provided at one end of the shell, a condensation chamber is provided at the other end, the air collecting hood is connected to the inner wall of the shell, and a reflux gap connecting the evaporation chamber and the condensation chamber is provided between the air collecting hood and the inner wall of the shell. The air collecting hood is provided with an air collecting groove opening toward the evaporation chamber, a bottom wall of the air collecting groove away from the evaporation chamber is provided with a plurality of air outlets respectively connecting the air collecting groove and the condensation chamber, and adjacent air outlets are arranged at intervals, and an air outlet pipe is correspondingly provided at each air outlet, one end of the air outlet pipe is connected to the bottom wall of the air collecting hood away from the evaporation chamber, and the other end extends toward the direction close to the condensation chamber, so that the evaporation chamber can be connected to the condensation chamber through the air collecting groove, the air outlet and the air outlet pipe in sequence.

[0006] In one embodiment, the air collecting hood includes a separation wall and a surrounding edge, the surrounding edge is arranged on one side of the separation wall close to the evaporation chamber and forms an air collecting groove, the air outlet is arranged on the separation wall, one end of the air outlet pipe is connected to the separation wall, and the other end extends toward the direction close to the condensation chamber.

[0007] In one embodiment, one end of the surrounding edge close to the evaporation chamber is connected to the inner wall of the shell, and the reflux gap is arranged between the surrounding edge and the shell.

[0008] In one of the embodiments, a plurality of protrusions distributed along the circumference of the surrounding edge are provided on the outer peripheral side of the surrounding edge, adjacent protrusions are arranged at intervals, and the surrounding edge is connected to the inner wall of the shell through the protrusions.

[0009] In one embodiment, the surrounding edge and the protrusion are integrally formed, or the surrounding edge and the protrusion are welded together.

[0010] In one of the embodiments, when the evaporation chamber and the condensation chamber are arranged along the vertical direction, the separation wall is inclined relative to the horizontal plane, and a reflux gap is provided on the side of the separation wall where the vertical height is the lowest.

[0011] In one of the embodiments, when the evaporation chamber and the condensation chamber are arranged along the vertical direction, the end surface of the air outlet pipe facing the condensation chamber is arranged horizontally.

[0012] In one embodiment, the air outlet pipe and the air collecting hood are an integrally formed structure.

[0013] The present application also provides an inverter cooling system, which includes the heat exchange device described in any one of the above embodiments.

[0014] The present application also provides a converter cooling system, which includes the heat exchange device described in any one of the above embodiments.

[0015] Compared with the prior art, the heat exchange device, inverter cooling system and converter cooling system provided in the present application can be understood that during use of the heat exchange device, the condensation chamber can be set above the evaporation chamber. When the liquid working fluid in the evaporation chamber is vaporized, it will rise and enter the gas collecting tank. After that, the gaseous working fluid continues to rise and enters the outlet pipe through the outlet port. Then, the gaseous working fluid enters the condensation chamber through the outlet pipe.

[0016] Furthermore, since a plurality of gas outlets are arranged at intervals and are respectively connected to the gas collecting grooves, after the gaseous working medium enters each gas outlet from the gas collecting groove, the flow area of ​​the gaseous working medium is reduced and the flow rate of the gaseous working medium is increased, so that the gaseous working medium can quickly rise to the top of the condensation chamber, which is beneficial to the sufficient cooling of the gaseous working medium in the condensation chamber, thereby improving the heat exchange efficiency of the heat exchange device.

[0017] Furthermore, since the gaseous working medium flows rapidly from the air outlet pipe to the condensation chamber, under the impact of the gaseous working medium, the condensed refluxed liquid working medium is difficult to enter the air outlet pipe, that is, most of the liquid working medium will first flow between the gas collecting hood and the inner wall of the shell when refluxing, and because a reflux gap connecting the evaporation chamber and the condensation chamber is provided between the gas collecting hood and the inner wall of the shell, the condensed liquid working medium can flow back to the evaporation chamber through the reflux gap.

[0018] From the above, it can be seen that in the heat exchange device provided in the present application, the condensed and refluxed liquid working medium is less likely to interfere with the vaporized gaseous working medium, and the evaporation chamber and condensation chamber of the present application are respectively arranged at both ends of the same shell, thereby greatly reducing the volume of the heat exchange device.

DETAILED DESCRIPTION

[0026] In devices such as inverters and converters, it is necessary to cool the power components inside the equipment (including but not limited to IGBT modules, chips, and motors, etc.). At present, the heat exchanger with the best heat exchange effect is the heat pipe heat exchanger, which mostly adopts a ring loop. Specifically, in the heat pipe heat exchanger, the working fluid in the evaporation section is heated and vaporized, and the working fluid vapor is transported to the condensation section through several pipes. After being cooled, it is condensed into liquid working fluid and flows back to the evaporation section through the return pipe. The whole cycle constitutes a ring loop.

[0027] At present, the problem with heat pipe heat exchangers is that, usually, the evaporation section and the condensation section are arranged in the same plane. If the steam pipe and the return pipe are located outside the above plane, the heat pipe heat exchanger will occupy a large space, resulting in the layout of the heat pipe heat exchanger being not compact enough. On the contrary, if the steam pipe and the return pipe are located in the above plane and arranged between the evaporation section and the condensation section, the rising steam of the evaporation section and the condensation liquid returning from the condensation section will interfere with each other, affecting the heat exchange efficiency of the heat pipe heat exchanger.

[0028] In order to solve the problem that the existing heat pipe heat exchanger cannot reduce its own volume while ensuring its own heat exchange efficiency, the present application provides a heat exchange device, an inverter cooling system and a converter cooling system.

[0029] See also Figure 1-Figure 5 The heat exchange device includes a shell 100, an air collecting hood 200 and an air outlet pipe 300. An evaporation chamber 110 is provided at one end of the shell 100, and a condensation chamber 120 is provided at the other end. The air collecting hood 200 is provided between the evaporation chamber 110 and the condensation chamber 120.

[0030] The gas collecting hood 200 is provided with a gas collecting groove 210 with an opening toward the evaporation chamber 110, and the bottom wall of the gas collecting groove 210 away from the evaporation chamber 110 is provided with a plurality of gas outlets 221 respectively connecting the gas collecting groove 210 and the condensation chamber 120, and adjacent gas outlets 221 are arranged at intervals, and each gas outlet 221 is correspondingly provided with an gas outlet pipe 300, one end of the gas outlet pipe 300 is connected to the bottom wall of the gas collecting hood 200 away from the evaporation chamber 110, and the other end extends toward the direction close to the condensation chamber 120, so that the evaporation chamber 110 can be connected to the condensation chamber 120 through the gas collecting groove 210, the gas outlet 221 and the gas outlet pipe 300 in sequence.

[0031] Specifically, in one embodiment, the air outlet pipe 300 and the air collecting cover 200 are integrally formed.

[0032] Specifically, the air collecting hood 200 is formed into the air outlet pipe 300 by stamping, or the air collecting hood 200 and the air outlet pipe 300 are integrally cast, or the air collecting hood 200 and the air outlet pipe 300 are 3D printed.

[0033] In another embodiment, the air outlet pipe 300 and the air collecting cover 200 may also be formed by welding.

[0034] Specifically, the portion of the shell 100 where the evaporation chamber 110 is provided and the portion of the shell 100 where the condensation chamber 120 is provided may be an integrally formed structure or a split welded structure.

[0035] It can be understood that during use of the heat exchange device, the condensation chamber 120 can be set above the evaporation chamber 110. When the liquid working medium in the evaporation chamber 110 is vaporized, it will rise and enter the gas collecting tank 210. Thereafter, the gaseous working medium continues to rise and enters the outlet pipe 300 through the outlet port 221. Then, the gaseous working medium enters the condensation chamber 120 through the outlet pipe 300.

[0036] Furthermore, since the plurality of gas outlets 221 are spaced apart and respectively connected to the gas collecting tank 210, after the gaseous working medium enters each gas outlet 221 from the gas collecting tank 210, the flow area of ​​the gaseous working medium is reduced and the flow rate of the gaseous working medium is increased, so that the gaseous working medium can quickly rise to the top of the condensation chamber 120, which is beneficial to sufficient cooling of the gaseous working medium in the condensation chamber 120, thereby improving the heat exchange efficiency of the heat exchange device.

[0037] Furthermore, the gas collecting hood 200 is connected to the inner wall of the shell 100, and a reflux gap 232 connecting the evaporation chamber 110 and the condensation chamber 120 is provided between the gas collecting hood 200 and the inner wall of the shell 100, so that the liquid working medium in the condensation chamber 120 can flow back to the evaporation chamber 110 through the reflux gap 232.

[0038] Since the gaseous working medium flows rapidly from the outlet pipe 300 to the condensation chamber 120, the condensed refluxed liquid working medium is difficult to enter the outlet pipe 300 under the impact of the gaseous working medium. That is, most of the liquid working medium will first flow to between the gas collecting hood 200 and the inner wall of the shell 100 when refluxing. Because a reflux gap 232 connecting the evaporation chamber 110 and the condensation chamber 120 is provided between the inner wall of the gas collecting hood 200 and the shell 100, the condensed liquid working medium can flow back to the evaporation chamber 110 through the reflux gap 232.

[0039] From the above, it can be seen that in the heat exchange device provided in the present application, the condensed and refluxed liquid working medium is less likely to interfere with the vaporized gaseous working medium, and the evaporation chamber 110 and the condensation chamber 120 of the present application are respectively arranged at the two ends of the same shell 100, thereby greatly reducing the volume of the heat exchange device.

[0040] In one embodiment, if Figure 2-Figure 4 As shown, the gas collecting hood 200 includes a separation wall 220 and a surrounding edge 230, wherein the surrounding edge 230 is arranged on one side of the separation wall 220 close to the evaporation chamber 110 and forms a gas collecting groove 210 with an opening toward the evaporation chamber 110. The gas outlet 221 is arranged on the separation wall 220, and one end of the gas outlet pipe 300 is connected to the separation wall 220, and the other end extends toward the direction close to the condensation chamber 120.

[0041] Specifically, in one embodiment, the separation wall 220 and the surrounding edge 230 are integrally formed, or the separation wall 220 and the surrounding edge 230 are welded and formed.

[0042] In one embodiment, the gas collecting hood 200 is connected to the inner wall of the shell 100 through an end of the surrounding edge 230 close to the evaporation chamber 110 , and the reflux gap 232 is provided between the surrounding edge 230 and the shell 100 .

[0043] With such an arrangement, the reflux gap 232 can be arranged at the bottom of the gas collecting hood 200 , so that the liquid working medium on the surface of the gas collecting hood 200 can flow into the evaporation chamber 110 through the reflux gap 232 , thereby avoiding liquid accumulation on the surface of the gas collecting hood 200 .

[0044] Further, in one embodiment, if Figure 2-Figure 4 As shown, the outer peripheral side of the surround 230 is provided with a plurality of protrusions 231 distributed along the circumference of the surround 230 , adjacent protrusions 231 are arranged at intervals, and the surround 230 is connected to the inner wall of the shell 100 (including but not limited to welding, clamping or bonding) through the protrusions 231 .

[0045] In this way, the surrounding edge 230 and the inner wall of the shell 100 are spaced apart, and the adjacent protrusions 231 , the side wall of the surrounding edge 230 and the inner wall of the shell 100 are arranged to form a reflux gap 232 , which greatly reduces the difficulty of processing the reflux gap 232 .

[0046] Furthermore, in one embodiment, the surrounding edge 230 and the protrusion 231 are integrally formed.

[0047] Specifically, the protrusion 231 is formed by stamping on the surrounding edge 230, or the surrounding edge 230 and the protrusion 231 are integrally cast, or the surrounding edge 230 and the protrusion 231 are 3D printed.

[0048] In another embodiment, the surrounding edge 230 and the protrusion 231 may also be formed by welding.

[0049] In another embodiment, the gas collecting hood 200 can also be connected to the inner wall of the shell 100 through one end of the surrounding edge 230 close to the condensation chamber 120, and the reflux gap 232 is arranged between the end of the surrounding edge 230 close to the condensation chamber 120 and the inner wall of the shell 100.

[0050] In one embodiment, if Figure 2-Figure 4 As shown, when the evaporation chamber 110 and the condensation chamber 120 are arranged along the vertical direction, the separation wall 220 is inclined relative to the horizontal plane, and a reflux gap 232 is provided on the side of the separation wall 220 where the vertical height is the lowest.

[0051] In this way, the liquid working medium that flows back to the separation wall 220 flows toward the reflux gap 232 under the action of gravity, thereby facilitating the rapid reflux of the liquid working medium.

[0052] Furthermore, in one embodiment, the power element 500 is disposed on a side of the evaporation chamber 110 close to the reflux gap 232 , so that the refluxed liquid medium can quickly take away the heat of the power element 500 .

[0053] Specifically, the power element 500 may be immersed in or partially immersed in the liquid working medium of the evaporation chamber 110 , and the power element 500 may also be attached to the outer wall of the housing 100 .

[0054] Further, in one embodiment, if Figure 2-Figure 4 As shown, a liquid accumulation prevention gap 233 is provided between the surrounding edge 230 disposed on the side with the highest vertical height of the separation wall 220 and the inner wall of the shell 100 , and the liquid accumulation prevention gap 233 connects the evaporation chamber 110 and the condensation chamber 120 .

[0055] By providing the anti-liquid accumulation gap 233 , it is possible to prevent liquid from accumulating between the surrounding edge 230 and the housing 100 on this side.

[0056] Further, in one embodiment, if Figure 3-Figure 4 As shown, when the evaporation chamber 110 and the condensation chamber 120 are arranged along the vertical direction, the end surface of the air outlet pipe 300 facing the condensation chamber 120 is horizontally arranged.

[0057] In this way, the gaseous working medium at various locations in the gas outlet pipe 300 can simultaneously leave the gas outlet pipe 300 and move upward.

[0058] However, it is not limited thereto. In other embodiments, when the evaporation chamber 110 and the condensation chamber 120 are arranged along the vertical direction, the end surface of the air outlet pipe 300 facing the condensation chamber 120 may also be arranged parallel to the separation wall 220 .

[0059] Such an arrangement is conducive to maintaining a consistent flow distance of the gaseous working medium at various locations in the outlet pipe 300 , that is, it is conducive to maintaining a consistent initial velocity of the gaseous working medium at various locations in the outlet pipe 300 when leaving the outlet pipe 300 .

[0060] In another embodiment, when the evaporation chamber 110 and the condensation chamber 120 are arranged along the vertical direction, the separation wall 220 may also be arranged horizontally.

[0061] In one embodiment, if Figure 5 As shown, the condensing chamber 120 includes a plurality of steam channels 121 which are arranged at intervals and respectively connected to the evaporating chamber 110 . The heat exchange device also includes fins 400 . The fins 400 are arranged between adjacent steam channels 121 so that the heat of the gaseous working medium in the steam channels 121 can be transferred to the fins 400 .

[0062] Further, in one embodiment, if Figure 1 and Figure 5As shown, the housing 100 is further provided with a balancing chamber 130 , which is arranged on a side of the steam channel 121 away from the evaporation chamber 110 , and a plurality of steam channels 121 are respectively connected to the balancing chamber 130 to balance the air pressure in each steam channel 121 .

[0063] The present application also provides an inverter cooling system, which includes the heat exchange device described in any one of the above embodiments.

[0064] The present application also provides a converter cooling system, which includes the heat exchange device described in any one of the above embodiments.
