[0122] In the related art, the liquid cooling distributor of the power module has a unique design and poor versatility. Before maintaining the equipment, the liquid in the water distributor and the equipment needs to be drained, and the equipment needs to be refilled after maintenance. Disassembly and maintenance are inconvenient and costly.

[0123] In order to solve this technical problem, the present application provides a liquid cooling distributor 300, which is described below with reference to Figures 1-8 The liquid cooling distributor 300 according to an embodiment of the present application is described.

[0124] like Figures 1-4 As shown, the liquid cooling distributor 300 of the embodiment of the present application includes: a distributor body 310 , a first stop valve 320 , a second stop valve 330 and a flow limiting member 340 .

[0125] like Figure 2 and Figure 3 As shown, the distributor body 310 has a water supply channel 311 , a water return channel 312 , a water inlet 313 , a water outlet 314 , a water supply port 315 and a water return port 316 .

[0126] The dispenser body 310 can be made of materials such as stainless steel, aluminum alloy, copper and its alloys, ceramic materials, polymer materials and composite materials.

[0127] In this embodiment, the distributor body 310 is made of aluminum alloy. The distributor body 310 made of aluminum alloy is lightweight, has good heat conduction effect, and is easy to process and manufacture.

[0128] The distributor body 310 is manufactured by machining and welding and can be processed as a whole from a metal block. When the output is large, it is appropriate to develop a profile mold to reduce costs.

[0129] The cross-sectional shape of the distributor body 310 can be rectangular, circular or other shapes. In this embodiment, the cross-sectional shape of the distributor body 310 is rectangular, which is easy to manufacture and assemble.

[0130] like Figure 2 As shown, the water supply channel 311 and the water return channel 312 are located inside the distributor body 310 .

[0131] The cross-sectional shapes of the water supply channel 311 and the return water channel 312 can be rectangular, circular or other shapes. In this embodiment, the cross-sectional shapes of the water supply channel 311 and the return water channel 312 are rectangular, which has a stable structure and is easy to install and maintain.

[0132] like Figure 5 As shown, one end of the water inlet 313 is connected to the external water supply pipe 380 , and the other end of the water inlet 313 is communicated with the water supply channel 311 .

[0133] One end of the water outlet 314 is connected to the external water outlet pipe 390 , and the other end of the water outlet 314 is communicated with the return water channel 312 .

[0134] One end of the water supply port 315 is communicated with the water supply channel 311 , and the other end of the water supply port 315 is communicated with the water inlet end of the cooling water pipe of the electrical device 1000 .

[0135] One end of the water return port 316 is communicated with the water return channel 312 , and the other end of the water return port 316 is communicated with the water outlet end of the cooling water pipe of the electrical device 1000 .

[0136] like Figure 4 As shown, there are multiple water supply ports 315 and multiple water return ports 316 .

[0137] like Figure 1 、 Figure 2 and Figure 4 As shown, in this embodiment, the water inlet 313 , the water supply channel 311 and the water supply port 315 are located on the same side of the distributor body 310 , and the water outlet 314 , the return water channel 312 and the return water port 316 are located on the other side of the distributor body 310 .

[0138] like Figure 1 and Figure 4 As shown, the first stop valve 320 is installed at the water inlet 313 .

[0139] The first stop valve 320 is used to control the flow of the water inlet 313 or adjust the flow of the water inlet 313.

[0140] The second stop valve 330 is installed at the water outlet 314 .

[0141] The second stop valve 330 is used to control the flow of the water outlet 314 or adjust the flow of the water outlet 314.

[0142] The first stop valve 320 and the second stop valve 330 can be rotary stop valves or lift stop valves.

[0143] like Figure 6 As shown, this embodiment uses a lifting stop valve, which controls the flow of the water inlet 313 and the water outlet 314 or adjusts the flow rate by raising or lowering the stop valve core.

[0144] The first stop valve 320 and the second stop valve 330 can be sealedly connected to the distributor body 310 using various sealing methods, such as flange connection, threaded connection, welding, and ferrule connection.

[0145] In this embodiment, the first stop valve 320 and the second stop valve 330 are sealedly connected to the distributor body 310 by threaded connection.

[0146] The multiple water supply ports and the multiple water return ports are used to form multiple branch flow channels.

[0147] At least one of the water supply port and the water return port corresponding to each branch flow channel is provided with a mounting structure for mounting a flow limiting component.

[0148] The flow restriction member 340 is installed in part or all of the water supply port 315 and the water return port 316 .

[0149] The flow restrictor 340 is installed in at least one of the following ways:

[0150] First, the water supply port 315 and the water return port 316 in the branch flow channel are not equipped with the flow limiting member 340 .

[0151] In this embodiment, the flow rates of the water supply port 315 and the water return port 316 are the largest.

[0152] Secondly, a flow limiting member 340 is provided at one of the water supply port 315 and the water return port 316 in the branch flow channel.

[0153] In this embodiment, the inflow rate or the outflow rate is controlled according to demand.

[0154] Thirdly, both the water supply port 315 and the water return port 316 in the branch flow channel are provided with flow limiting components 340 .

[0155] In this embodiment, the flow rates of the water supply port 315 and the water return port 316 are minimum.

[0156] like Figure 4 As shown, in this embodiment, the flow limiting members 340 are installed in all the water supply ports 315 and the water return ports 316 .

[0157] The flow limiter 340 can be a mechanical flow limiter or an electronic flow limiter.

[0158] like Figure 1 As shown, in this embodiment, the flow limiting member 340 is a flow limiting ring in a mechanical flow limiter.

[0159] In the related art, the liquid cooling distributor of the power module has a unique design and poor versatility. Before maintaining the electrical equipment, the liquid in the water distributor and the electrical equipment needs to be drained, and the electrical equipment needs to be refilled after maintenance. Disassembly and maintenance are inconvenient and costly.

[0160] The liquid cooling distributor 300 of this embodiment is provided with a first stop valve 320 at the water inlet 313, and a second stop valve 330 at the water outlet 314. One end of the water inlet 313 is connected to the external water supply pipe 380, and the other end of the water inlet 313 is connected to the water supply channel 311. One end of the water outlet 314 is connected to the external water outlet pipe 390, and the other end of the water outlet 314 is connected to the return water channel 312. When the first stop valve 320 and the second stop valve 330 are opened, the liquid in the external water supply pipe 380 flows into the water supply channel 311 through the water inlet 313. A water supply port 315 is provided on the same side of the water supply channel 311. The liquid flows into the water inlet end of the cooling water pipe of the electrical equipment 1000 through the water supply port 315. The liquid cools the electrical equipment 1000 through the cooling water pipe. After the cooling is completed, the liquid The liquid flows into the return water channel 312 through the return water port 316 connected to the outlet end of the cooling water pipe, and finally flows into the external water outlet pipe 390 through the outlet 314; when the heat dissipation demand of the electrical equipment 1000 changes, the liquid flow rate flowing into the cooling water pipe of the electrical equipment 1000 is adjusted by changing the opening of the first stop valve 320 or replacing the flow limiting member 340 with a different inner diameter, which can be adjusted according to the heat dissipation demand of the electrical equipment 1000 without replacing the liquid cooling distributor 300, saving costs; when the electrical equipment 1000 needs to be maintained and disassembled, the first stop valve 320 and the second stop valve 330 are closed, and the external water supply pipe 380 and the external water outlet pipe 390 can be removed, and the liquid in the electrical equipment 1000 will not flow out, maintenance and disassembly are relatively simple, cost-effective, and efficient and safe.

[0161] According to the liquid-cooled distributor 300 provided in the embodiment of the present application, a first stop valve is set at the water inlet and a second stop valve is set at the water outlet. During maintenance, there is no need to drain the liquid from the liquid-cooled distributor, and maintenance and disassembly are relatively simple. By setting flow limiting components at the water supply port and the return port, the application range of the liquid-cooled distributor can be improved, and the cost is low and the efficiency and safety are high.

[0162] In some embodiments, as Figure 1 、 Figure 2 and Figure 4As shown, the water supply channel 311 and the return water channel 312 can be spaced apart along the first direction and both extend along a second direction intersecting the first direction. Multiple water supply ports 315 are spaced apart and distributed along the second direction, and multiple return water ports 316 are spaced apart and distributed along the second direction.

[0299] According to the support frame assembly 100 provided in the embodiment of the present application, the electronic device 500 is installed on the support frame 110, and the liquid cooling distributor 300 and the liquid cooling radiator 600 are used to cool the electronic device 500 to ensure the normal operation of the electronic device 500. The booster 120 is rotated under force and applies thrust to the first component 400, thereby achieving the sliding of the support frame 110 relative to the first component 400, thereby facilitating the rapid disassembly and assembly of the electronic device.

[0300] In some embodiments, as Figure 16 As shown, the booster 120 may include a booster rod 121 and a limiter 123 .

[0301] The power assist lever 121 is rotatably mounted on the support frame 110 .

[0302] The power lever 121 includes a first portion 1211 and a second portion 1212 of the above embodiment.

[0303] In this embodiment, the booster 120 may further include a shaft sleeve 122 .

[0305] The limiter 123 is used to fix the power-assisting rod 121 on the supporting frame 110 .

[0306] The power-assisting rod 121 or the supporting frame 110 is detachably connected to the limiter 123 . In some embodiments, the power-assisting rod 121 and the supporting frame 110 may also be detachably connected to the limiter 123 .

[0307] When the support frame 110 is installed on the first component 400 , the power rod 121 is fixed to the support frame 110 through the limiter 123 . When the support frame 110 is disassembled, the limiter 123 is disconnected from the support frame 110 , so that the power rod 121 is separated from the support frame 110 .

[0308] According to the support frame assembly 100 provided in the embodiment of the present application, the power rod 121 is fixed to the support frame 110 through the limiter 123, and the support frame 110 and the limiter 123 are detachably connected to facilitate the fixation and disassembly of the power rod 121.

[0309] In some embodiments, the stopper 123 may be in at least one of the following structural forms:

[0310] First, as Figure 16 As shown, the limiter 123 may include: a threaded connection.

[0311] The support frame 110 is provided with threads, and the threaded connector is threadedly connected to the support frame 110 .

[0312] The threaded connection piece is rotatably mounted on the power assist rod 121 .

[0313] The threaded connector can be removed from or installed on the support frame 110 by rotating on the power rod 121 .

[0314] In this embodiment, the threaded connection is a captive screw. When the power-assisting rod 121 is used, the captive screw is loosened so that the captive screw will not fall off, thereby avoiding loss or popping out when the device is working, affecting the operation of the device. When the power-assisting rod 121 is not used, the captive screw can be tightened. In some embodiments, the threaded connection can also be a bolt, which has high connection strength and is easy to disassemble and assemble.

[0315] Secondly, the limiter 123 may include: a positioning pin.

[0316] The support frame 110 and the power rod 121 are provided with positioning holes.

[0317] The positioning pins are used to cooperate with the positioning holes on the support frame 110 and the power-assisting rod 121 .

[0318] The head of the outer end of the positioning pin is provided with a gripping portion to facilitate the disassembly and assembly of the positioning pin.

[0319] The grip portion can adopt a variety of structures. In this embodiment, a ring handle is selected, which is comfortable to hold and easy to operate.

[0320] In this embodiment, the power rod 121 can be fixed by inserting the positioning pin into the positioning holes on the support frame 110 and the power rod 121. When the power rod 121 is used, the positioning pin can be pulled out, which is easy to disassemble and assemble.

[0325] In some embodiments, as Figure 16 As shown, the length of the first portion 1211 is smaller than that of the second portion 1212 .

[0441] In this embodiment, the elastic member 220 is a disc spring, and a plurality of disc springs are mounted on the sleeve 210 in a stacked manner.

[0442] The ejector pin 230 is slidably assembled on the sleeve 210 , and the ejector pin 230 is used to apply a pressing force to the power module stack assembly 700 .

[0443] The adjusting member 240 is threadedly connected to the sleeve 210 and abuts against the ejector pin 230 . The adjusting member 240 is used to rotate in the sleeve 210 and push the ejector pin 230 to press the power module stack assembly 700 .

[0444] like Figure 21 As shown, the power module stack assembly 700 is pressed into the support frame 110 by the ejector pins 230 .

[0445] In the related art, the reliability of the crimping components of the power module is poor, which can easily affect the normal operation of the power module.

[0446] If the power module stack assembly 700 rotates during the installation process, it will cause the power module stack assembly 700 to be not in the preset installation position, which will bring safety hazards and make it difficult to achieve the ideal crimping effect. In the crimping assembly 200 of this embodiment, the power module stack assembly 700 is installed in the support frame 110, the elastic member 220 applies initial pressure to the power module stack assembly 700, the adjusting member 240 rotates along the thread in the sleeve 210 and then pushes the push rod 230 to move along the axis, the push rod 230 contacts the power module stack assembly 700 and gradually applies crimping force to fix the power module stack assembly 700 in the support frame 110. Since the push rod 230 only performs linear motion, it will not drive the power module stack assembly 700 to rotate. When the crimping force needs to be adjusted, the adjusting member 240 can continue to be rotated to increase or decrease the crimping force. It should be noted that the specific structure of the support frame 110 in this embodiment is shown in the above embodiment.

[0447] In the power module provided by the embodiment of the present application, the rotation of the adjustment member 240 drives the linear motion of the ejector pin 230, which abuts against the power module stack assembly 700 and presses the power module stack assembly 700 into the support frame 110. The press-fit assembly 200 remains stable and prevents rotation during installation, preventing rotation of the power module stack assembly 700 pressed by the press-fit assembly 200 and maintaining relative stability.

[0448] In some embodiments, as Figure 22 As shown, the sleeve 210 may include: a first channel 211 , and the crimping assembly 200 may further include: a first anti-rotation structure 250 .

[0449] The first channel 211 is cylindrical, which is convenient for assembly. The push rod 230 is slidably assembled in the first channel 211 .

[0450] The first anti-rotation structure 250 is located between the push rod 230 and the sleeve 210 . The first anti-rotation structure is used to prevent the push rod 230 from rotating in the first channel 211 .

[0451] The first anti-rotation structure 250 is a non-rotating body, and the cross section of the first anti-rotation structure 250 can be circular, rectangular, or other polygonal.

[0452] According to the power module provided in the embodiment of the present application, a cylindrical first channel 211 and a first anti-rotation structure 250 are provided in the sleeve 210, so that the top rod 230 can slide along the axial direction without rotating, and will not damage the contact surface between the power module stack assembly 700 and the top rod 230.

[0453] In some embodiments, as Figure 20 As shown, the first anti-rotation structure 250 may include: a first limiting block 252 .

[0454] A first limiting groove 251 is provided on the push rod 230 or the sleeve 210 . If the push rod 230 or the sleeve 210 is not provided with the first limiting groove 251 , a positioning groove is provided, and the first limiting block 252 is installed in the positioning groove.

[0455] The first limiting block 252 is slidably engaged with the first limiting groove 251 .

[0456] In this embodiment, a first limiting groove 251 is provided on the sleeve 210 , a positioning groove is provided on the push rod 230 , and the first limiting block 252 is installed in the positioning groove of the push rod 230 .

[0457] When the adjusting member 240 rotates in the sleeve 210 and then pushes the push rod 230 to move along the axis, there is friction between the adjusting member 240 and the push rod 230. At this time, the first limit block 252 is installed in the positioning groove and the first limit block 252 slides along the first limit groove 251 to limit the rotation of the push rod 230.

[0458] In some embodiments, the first limiting block 252 may also be integrated with the push rod 230 or the sleeve 210 , and the push rod 230 or the sleeve 210 that does not have the first limiting block 252 is provided with a first limiting groove 251 .

[0459] According to the crimping assembly 200 provided in the embodiment of the present application, the first limiting block 252 is provided to slide along the first limiting groove 251 to prevent the adjusting member 240 from rotating and thereby driving the ejector rod 230 to rotate.

[0460] In some embodiments, as Figure 19 and Figure 20 As shown, the crimping assembly 200 may further include a second anti-rotation structure 260 .

[0461] In this embodiment, the outer peripheral wall 213 of the sleeve 210 may be cylindrical, and the outer peripheral wall 213 of the sleeve 210 is used for sliding assembly on the support frame 110 .

[0462] like Figure 19 As shown, the second anti-rotation structure 260 is disposed on the outer peripheral wall 213 of the sleeve 210 .

[0463] It is understandable that the second anti-rotation structure 260 may adopt the same structure as the first anti-rotation structure 250 in the above embodiment.

[0464] In some embodiments, the outer peripheral wall 213 of the sleeve 210 may also be rectangular or have other shapes.

[0465] According to the crimping assembly 200 provided in the embodiment of the present application, a cylindrical outer peripheral wall 213 and a second anti-rotation structure 260 are provided outside the sleeve 210 so that when the adjusting member 240 rotates inside the sleeve 210 , the sleeve 210 will not rotate along with it.

[0466] In some embodiments, as Figure 20 As shown, the sleeve 210 may have a threaded bore 212 .

[0467] The push rod 230 is slidably assembled in the first channel 211 and extends into the threaded hole 212 . The adjusting member 240 is threadedly connected to the threaded hole 212 .

[0468] The first channel 211 and the sleeve 210 are coaxially arranged.

[0469] The adjusting member 240 rotates along the thread to push the push rod 230 to move linearly along the first channel 211 .

[0470] According to the crimping assembly 200 provided in the embodiment of the present application, a threaded hole 212 is provided in the sleeve 210 to facilitate the adjustment member 240 to rotate along the thread.

[0471] In some embodiments, as Figure 19 and Figure 20 As shown, the push rod 230 may include a spherical surface 231 .

[0472] The spherical surface 231 is located at an end of the push rod 230 facing away from the adjusting member 240 .

[0473] The spherical surface 231 can be made of the same material as the push rod 230 , or the spherical surface 231 can be made of a different material from the push rod 230 .

[0474] In this embodiment, the push rod 230 is made of metal material, and the end of the push rod 230 away from the adjusting member 240 is covered with a spherical surface 231 made of flexible material, such as a metal push rod 230 and a rubber spherical surface 231 used in combination.

[0475] According to the crimping assembly 200 provided in the embodiment of the present application, a spherical surface 231 is provided at one end of the ejector pin 230 to ensure that the crimping force is applied against the power module stack assembly 700 while minimizing damage to the contact surface.

[0476] An embodiment of the present application also provides a power module.

[0477] like Figure 9 and Figure 10 As shown, the power module includes: a support frame 110 , a crimping assembly 200 and a power module stack assembly 700 .

[0478] like Figure 11-Figure 15 As shown, the support frame 110 may include a first side plate 1112 and a second side plate 1113 .

[0479] like Figure 11-13 and Figure 15 As shown, the first side plate 1112 and the second side plate 1113 are spaced apart from each other to form a receiving cavity.

[0480] The crimping assembly 200 is the crimping assembly 200 of the above embodiment.

[0481] The crimping assembly 200 is installed on the first side plate 1112 or the second side plate 1113 . In some embodiments, the crimping assembly 200 can also be installed on the first side plate 1112 and the second side plate 1113 .

[0482] In this embodiment, the crimping assembly 200 is installed on the first side plate 1112 and the second side plate 1113 .

[0483] The power module stack assembly 700 is press-fitted between the first side plate 1112 and the second side plate 1113 by the ejector pin 230 of the press-fit assembly 200 .

[0484] According to the power module provided in the embodiment of the present application, the power module stack assembly 700 is crimped between the first side plate 1112 and the second side plate 1113 of the support frame 110 through the top rod 230 of the crimping assembly 200. The power module structure is simple and easy to install, disassemble and maintain.

[0485] In some embodiments, as Figure 23 and Figure 24 As shown, the power module stack assembly 700 includes a crimping block 710 and an insulating block 720 .

[0486] The pressing blocks 710 are located at both ends of the power module stack assembly 700 . The pressing blocks 710 are used to press the stacked and staggered liquid cooling radiators 600 and the press-fit power devices after contacting the ejector pins 230 .

[0487] It is understandable that the press-fit power device in this embodiment is as follows Figure 23 and Figure 24 The electronic device 500 is shown.

[0488] The ejector pin 230 abuts against at least one crimping block 710 . In this embodiment, the ejector pin 230 abuts against two crimping blocks 710 located at both ends of the power module stack assembly 700 .

[0490] A plurality of stacked and staggered liquid cooling heat sinks 600 and press-fit power devices are press-fitted between the insulating blocks 720 on both sides.

[0491] The insulating block 720 can be made of materials such as ceramic, rubber and composite materials.

[0492] In this embodiment, the insulating block 720 is made of aluminum nitride or silicon nitride. The insulating block 720 can assist in heat dissipation while providing electrical insulation.

[0493] According to the power module provided in the embodiment of the present application, by setting the crimping block 710 and the insulating block 720, multiple stacked and staggered liquid-cooled heat sinks 600 and crimped power devices can be crimped in the support frame 110, and electrical insulation is performed to avoid short circuits, and the stability and reliability are high.

[0500] It should be noted that, depending on the electrical solution, some IGCT modules 510 can be replaced by insulation spacers 730, but not vice versa. The number of power module groups is determined by the electrical solution.

[0501] According to the power module provided in the embodiment of the present application, a power module is formed by arranging liquid cooling heat sinks 600 on both sides of the IGCT module 510, and multiple groups of power modules are crimped between the crimping block 710, the insulating block 720 and the insulating spacer 730, so as to ensure that the IGCT module 510 operates normally while being electrically insulated to avoid short circuits, and has high stability and reliability.

[0502] In some embodiments, as Figure 24 As shown, the power module stack assembly 700 may be a diode 520 power string.

[0503] In the case where the power module stack assembly 700 is a diode 520 power string, the press-fit power device includes the diode 520 .

[0504] The multiple stacked and staggered liquid cooling heat sinks 600 and press-fit power devices comprise multiple groups of power modules.

[0505] An insulating spacer 730 is crimped between two adjacent groups of power modules, and a busbar 360 and a diode 520 are crimped between the outermost group and the insulating block 720 .

[0506] Each group of power modules includes a plurality of liquid-cooled radiators 600 and diodes 520 , and both ends of the outermost side of each group are liquid-cooled radiators 600 .

[0511] like Figures 1-4 As shown, the liquid cooling distributor 300 includes: a distributor body 310 , a first stop valve 320 , a second stop valve 330 and a flow limiting member 340 .

[0512] like Figure 2 and Figure 3 As shown, the distributor body 310 has a water supply channel 311 , a water return channel 312 , a water inlet 313 , a water outlet 314 , a water supply port 315 and a water return port 316 .

[0513] The dispenser body 310 can be made of materials such as stainless steel, aluminum alloy, copper and its alloys, ceramic materials, polymer materials and composite materials.

[0514] In this embodiment, the dispenser body 310 is made of aluminum alloy.

[0515] The distributor body 310 is manufactured by machining and welding and can be processed as a whole from a metal block. When the output is large, it is appropriate to develop a profile mold to reduce costs.

[0516] The cross-sectional shape of the distributor body 310 can be rectangular, circular or other shapes. In this embodiment, the cross-sectional shape of the distributor body 310 is rectangular, which is easy to manufacture and assemble.

[0517] like Figure 2 As shown, the water supply channel 311 and the water return channel 312 are located inside the distributor body 310 .

[0518] The cross-sectional shapes of the water supply channel 311 and the return water channel 312 can be rectangular, circular or other shapes. In this embodiment, the cross-sectional shapes of the water supply channel 311 and the return water channel 312 are rectangular, which has a stable structure and is easy to install and maintain.

[0519] One end of the water inlet 313 is connected to the external water supply pipe 380 , and the other end of the water inlet 313 is communicated with the water supply channel 311 .

[0522] One end of the water return port 316 is connected to the water return channel 312 , and the other end of the water return port 316 is connected to the water outlet end of the cooling water pipe of the power module.

[0523] like Figure 4 As shown, there are multiple water supply ports 315 and multiple water return ports 316 .

[0524] like Figure 1 、 Figure 2 and Figure 4 As shown, in this embodiment, the water inlet 313 , the water supply channel 311 and the water supply port 315 are located on the same side of the distributor body 310 , and the water outlet 314 , the return water channel 312 and the return water port 316 are located on the other side of the distributor body 310 .

[0525] The first stop valve 320 is installed at the water inlet 313 .

[0526] The first stop valve 320 is used to control the flow of the water inlet 313 or adjust the flow of the water inlet 313.

[0527] The second stop valve 330 is installed at the water outlet 314 .

[0528] The second stop valve 330 is used to control the flow of the water outlet 314 or adjust the flow of the water outlet 314.

[0529] The first stop valve 320 and the second stop valve 330 can be rotary stop valves or lift stop valves.

[0530] like Figure 6 As shown, this embodiment uses a lifting stop valve, which controls the flow of the water inlet 313 and the water outlet 314 or adjusts the flow rate by raising or lowering the stop valve core.

[0531] The first stop valve 320 and the second stop valve 330 can be sealedly connected to the distributor body 310 using various sealing methods, such as flange connection, threaded connection, welding, and ferrule connection.

[0532] In this embodiment, the first stop valve 320 and the second stop valve 330 are sealedly connected to the distributor body 310 by threaded connection.

[0533] The flow restriction member 340 is installed in part or all of the water supply port 315 and the water return port 316 .

[0534] The flow restrictor 340 is installed in at least one of the following ways:

[0535] First, the water supply port 315 and the water return port 316 in the branch flow channel are not equipped with the flow limiting member 340 .

[0536] In this embodiment, the flow rates of the water supply port 315 and the water return port 316 are the largest.

[0537] Secondly, a flow limiting member 340 is provided at one of the water supply port 315 and the water return port 316 in the branch flow channel.

[0538] In this embodiment, the inflow rate or the outflow rate is controlled according to demand.

[0539] Thirdly, both the water supply port 315 and the water return port 316 in the branch flow channel are provided with flow limiting components 340 .

[0540] In this embodiment, the flow rates of the water supply port 315 and the water return port 316 are minimum.

[0541] like Figure 1 As shown, in this embodiment, the flow limiting members 340 are installed in all the water supply ports 315 and the water return ports 316 .

[0542] The current limiting element 340 can be a mechanical current limiter or a power current limiter.

[0543] like Figure 1 As shown, in this embodiment, the flow limiting member 340 is a flow limiting ring in a mechanical flow limiter.

[0544] According to the power module provided in the embodiment of the present application, a first stop valve is provided at the water inlet and a second stop valve is provided at the water outlet. During maintenance, there is no need to drain the liquid in the liquid-cooled distributor, and maintenance and disassembly are relatively simple. By providing flow limiting components at the water supply port and the return port, the application range of the liquid-cooled distributor can be improved, and the cost is low while the efficiency and safety are high.

[0545] In some embodiments, some electronic devices 500 of the electrical equipment 1000 are crimped together with the crimping block 710, the insulating block 720 and the insulating spacer 730 of the power module stack assembly 700 to form a power string. The power string is crimped between the first side plate 1112 and the second side plate 1113 of the support frame 110 through the crimping assembly 200. The elastic member 220 of the crimping assembly 200 applies initial pressure to the power string, and the adjusting member 240 is rotated. The adjusting member 240 rotates along the thread of the sleeve 210 and pushes the top rod 230 to abut against the crimping block 710 of the power string and apply crimping force. The liquid cooling distributor 300 is installed in the front lower frame 114 of the support frame 110, and the remaining electronic devices 500 are installed in the front upper frame of the support frame 110. 113, the pipe 370 connected to the branch water nozzle 350 of the liquid-cooled distributor 300 passes through the limiting hole 1151 of the limiting beam 115 and is connected to the liquid-cooled radiator 600 of the first row of power strings. The liquid-cooled radiators 600 between the power strings are also connected through the pipe 370 erected in the limiting hole 1151. The tail end of the pipe 370 is connected to the water outlet 314. A first stop valve 320 is set at the water inlet 313 of the liquid-cooled distributor 300, and a second stop valve 330 is set at the water outlet 314. One end of the water inlet 313 is connected to the external water supply pipe 380, and the other end of the water inlet 313 is connected to the water supply channel 311. One end of the water outlet 314 is connected to the external water outlet pipe 390, and the other end of the water outlet 314 is connected to the return water channel 312.

[0546] When the first stop valve 320 and the second stop valve 330 are opened, the liquid in the external water supply pipe 380 flows into the water supply channel 311 through the water inlet 313. A water supply port 315 is provided on the same side of the water supply channel 311. The liquid flows into the water inlet end of the cooling water pipe of the electrical equipment 1000 through the water supply port 315. The liquid cools the electrical equipment 1000 through the cooling water pipe. After cooling, the liquid flows into the return water channel 312 through the return water port 316 connected to the water outlet end of the cooling water pipe. Finally, the liquid flows into the external water outlet pipe 390 through the water outlet 314. When the heat dissipation of the electrical equipment 1000 is required, When the heat dissipation requirement of the electrical equipment 1000 needs to be changed, the liquid flow rate flowing into the cooling water pipe of the electrical equipment 1000 can be adjusted by changing the opening of the first stop valve 320 or replacing the flow limiting member 340 with a different inner diameter. This can be adjusted according to the heat dissipation requirement of the electrical equipment 1000 without replacing the liquid cooling distributor 300, saving costs. When the electrical equipment 1000 needs to be maintained or disassembled, the first stop valve 320 and the second stop valve 330 are closed, and the external water supply pipe 380 and the external water outlet pipe 390 can be removed. The liquid in the electrical equipment 1000 will not flow out, and maintenance and disassembly are relatively simple, low cost, and high efficiency and safety.

[0547] When the electronic device 500 needs to be disassembled for maintenance, the connection between the limiter 123 and the support frame 110 is released and the power rod 121 is rotated. The power rods 121 on both sides of the support frame 110 contact the fixed blocks fixed on the slide rail 420. The support frame 110 is subjected to opposite forces and moves along the slide rail 420 relative to the base 410. The support frame 110 is separated from the base 410, the first stop valve 320 and the second stop valve 330 are closed, the external water supply pipe and the outlet pipe are removed, the adjusting part 240 is rotated to release the crimping force between the top rod 230 and the crimping block 710, the power string is removed for maintenance.

[0548] According to the electrical equipment 1000 of the present application, the support frame 110 is easily removed from the base 410 through the power rod 121, the slide rail 420 and the sliding structure 1111, the first stop valve 320 and the second stop valve 330 control the liquid on and off and the flow rate, the different inner diameters of the flow limiting member 340 control the flow into the branch water nozzle 350, and the crimping assembly 200 makes the power string easy to install and disassemble for maintenance.
