Description

Technical Field

[0001] The present invention belongs to the technical field of heat dissipation of charging cabinets, and in particular relates to a liquid cooling heat dissipation device for a charging cabinet. Background Art

[0002] A charging cabinet is a device specifically used for centralized storage and charging. Since the charging cabinet generates a certain amount of heat during operation, it usually needs to be equipped with a heat dissipation device.

[0003] For example, the Chinese invention patent entitled "A Liquid Cooling Device for a Charging Cabinet and Its Power Control System" has an application number of 202411383892.8. It specifically discloses a heat dissipation device comprising a cabinet, a liquid cooling mechanism provided on the cabinet, a mounting frame fixedly mounted in the cabinet, a device body provided on the mounting frame, a porous air jet tube rotatably provided on the mounting frame for cooling the device body, and a rotating mechanism for driving the porous air jet tube to rotate. A plurality of liquid cooling columns are fixedly mounted in the cabinet, a plurality of heat sinks are provided on the liquid cooling columns, a cold water cavity is defined in the liquid cooling columns, a piston cavity is provided in the liquid cooling columns, a disturbance mechanism is provided in the piston cavity, the disturbance mechanism comprises a fixed tube, a first telescopic tube is inserted into the fixed tube, a second telescopic tube is slidably inserted into the first telescopic tube, a cooling mechanism is provided on the liquid cooling column, and the porous air jet tube is connected to the cooling mechanism. The cooling mechanism draws gas in the cabinet into the piston cavity and cools it in the piston cavity, and then ejects the cooled gas through the porous air jet tube to directly cool the device body, thereby achieving the purpose of improving the cooling effect.

[0004] However, there are the following problems in this process: First, the device body generates heat when working, causing the temperature inside the charging cabinet to continue to rise. After the cooling water enters the charging cabinet, due to the large temperature difference between the inside and outside, it is easy to form dew on the surface of the liquid cooling column. When the dew comes into contact with the hot air in the charging cabinet, it will produce water vapor, making the charging cabinet humid and easily causing equipment failure; second, this device relies on multiple linked mechanical mechanisms, which takes up a large space and reduces the internal storage capacity. Summary of the Invention

DETAILED DESCRIPTION

[0032] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] like Figures 1-13 As shown, this embodiment provides a liquid cooling and heat dissipation device for a charging cabinet, including a shell 10, a frame 20, a liquid cooling circulation component 30, and a ventilation component 40.

[0034] Specifically, such as Figure 1-Figure 3 As shown, the shell 10 is a rectangular cavity structure with an opening on one side. Door panels 11 are rotatably connected at both ends of the opening. A ring-shaped seal 13 is provided on the inner side of the door panel 11. When the door panel 11 is closed, the outer side of the seal 13 is stuck into the inner wall of the opening of the shell 10 to seal the docking surface between the shell 10 and the door panel 11. A rubber strip is vertically provided at the docking point of the two door panels 11 to seal the docking point of the two door panels 11 when closed, so as to achieve the closure of the interior of the shell 10. A lock is provided on the outer side of the door panel 11 to connect the two door panels 11 when closed.

[0035] The door panel 11 is a rectangular plate-like structure with a hollow interior. The inner wall panel of the door panel 11 is covered with through holes. The distribution range of the through holes is located within the area surrounded by the seal 13. The surface of the through hole distribution range is covered with a filter 12. The filter 12 is connected to the door panel 11 by bonding. Specifically, magnetic attraction can be used. A magnetic strip is set around the filter 12 facing the inner wall of the door panel 11, and the filter is connected to the door panel 11 through the magnetic strip. The magnetic strip can also be replaced with a double-sided adhesive strip for bonding.

[0036] like Figure 4-Figure 9 As shown, the frame 20 includes a plurality of shelves 21 arranged along the height direction of the shell 10. Each shelf 21 is a rectangular frame structure. A plurality of reinforcing ribs 211 are arranged in an array inside the rectangular structure shelf 21. The length direction of the reinforcing ribs 211 is arranged parallel to the width direction of the shelf 21 to improve the bearing capacity of the shelf 21, thereby improving the overall stability of the frame 20.

[0037] like Figure 4 、 Figure 7-10 A limiting strip 212 is provided on the top surface of the shelf 21 facing the inside of the shell 10. The length direction of the limiting strip 212 is consistent with the length direction of the shelf 21, and the side of the limiting strip 212 facing the inside of the shell 10 is flush with the side of the shelf 21 facing the inside of the shell 10. The width of the limiting strip 212 is smaller than the width of the inner frame edge of the shelf 21, so that the cross-section of the inner frame edge of the shelf 21 and the cross-section of the limiting strip 212 form an L-shaped structure.

[0038] The top surfaces of both ends of the layer shelf 21 are recessed with guide grooves 213, which are arranged along the width direction of the layer shelf 21. Right-angle rods 214 are respectively provided at both ends of the limit strip 212, and the inner right angles of the right-angle rods 214 face inside the layer shelf 21. The end of the guide groove 213 facing the inside of the shell 10 corresponds to the middle of the right-angle side of the right-angle rod 214 connecting to the limit strip 212.

[0039] A limit block 216 is vertically provided at the other end of the guide groove 213, and the limit block 216 corresponds to the right-angle side of one side of the right-angle rod 214 connecting the limit strip 212, and the length of the limit block 216 is consistent with the inner side length of the right-angle side of one side of the right-angle rod 214 connecting the limit strip 212; a vertical plate 215 is vertically provided on one side of the limit block 216, and the vertical plate 215 corresponds to the other right-angle side of the right-angle rod 214, and the width of the vertical plate 215 is consistent with the width of the other right-angle side of the right-angle rod 214.

[0040] like Figure 4 、 Figure 7 As shown, the liquid cooling circulation component 30 includes a refrigerator 31, a liquid inlet pipe 32, a serpentine pipe 33, a diversion pipe 34, a cavity plate 35, a conduit 36, a liquid outlet pipe 37, and a partition 38. The refrigerator 31 is installed on the outside of the shell 10, and the input end of the liquid inlet pipe 32 is connected to the output end of the refrigerator 31. The output end of the liquid inlet pipe 32 passes through the shell 10 and is connected to the input end of the serpentine pipe 33; the serpentine pipe 33 is arranged between the side of the frame 20 facing the shell 10 and the inner wall of the shell 10 in the length direction; the two sides of the distribution trajectory of the serpentine pipe 33 have a predetermined distance from the frame 20 and the inner wall of the shell 10 in the length direction respectively, and the output end of the serpentine pipe 33 is provided with an extension pipe 331, which is extended along the side of the opening of the shell 10 in the width direction of the frame 20, and the input end of the diversion pipe 34 is connected to the output end of the extension pipe 331.

[0041] Multiple cavity plates 35 are arranged in parallel and at intervals along the height direction of the frame 20, and are arranged one by one on the shelf 21. The four corners of the cavity plate 35 are respectively engaged with the inner right angle of the right-angle rod 214 and the right-angle structure formed at the inner joint of the vertical plate 215 and the limit block 216, so that the cavity plate 35 is engaged with the corresponding top surface of the shelf 21, which is used to limit the horizontal direction of the cavity plate 35 to prevent the cavity plate 35 from moving horizontally when the battery pack 1 is moved, and when the cavity plate 35 is placed on the top surface of the shelf 21, the top surface height of the limit bar 212 is higher than the height of the top surface of the cavity plate 35, which is used to limit one end of the battery pack 1 toward the limit bar 212 to prevent the battery pack 1 from extending out of the shelf 21 and colliding with the components on the outside of the shelf 21.

[0042] The diverter pipe 34 and the converging pipe 36 are respectively arranged vertically at the two ends of the distribution track of the cavity plate 34; the input end of the cavity plate 35 is provided with an inlet pipe 351, and the output end of the cavity plate 35 is provided with an outflow pipe 352. The input ends of all inlet pipes 351 are connected to the output end of the diverter pipe 34, and the output ends of all outflow pipes 352 are connected to the input end of the converging pipe 36.

[0043] The output end of the inlet pipe 36 is connected to the input end of the liquid outlet pipe 37 , and the output end of the liquid outlet pipe 37 is connected to the input end of the refrigerator 31 , thereby forming a liquid cooling circulation system.

[0044] The partition 38 is vertically arranged between the shell 10 and the frame 20 to prevent the temperature difference between the coolant that has just entered the serpentine tube 33 and the air inside the shell 10 from being too large, so as to prevent the water vapor formed on the side of the frame 20 close to the serpentine tube 33 from directly contacting the battery pack 1 and affecting the use of the battery pack 1. The partition 38 divides the inner cavity of the shell 10 into a strong cooling chamber 14 and a weak cooling chamber 15. The partition 38 can be made of moisture-proof metal material, such as galvanized steel plate, or plastic material, such as polyethylene or polypropylene.

[0045] The ventilation assembly 40 includes an exhaust fan 41, a connecting hose 42, and an air supply pipe 43. The exhaust fan 41 is arranged at the bottom of the frame 20. The output end of the exhaust fan 41 is connected to the output end of the connecting hose 42. The input end of the connecting hose 42 passes through the inner wall of the filter plate 12 and the door panel 11 in sequence and then communicates with the hollow inner wall of the door panel 11; the air supply pipe 43 is arranged at the output end of the exhaust fan 41. The output end of the air supply pipe 43 passes through the partition 38 and then extends into the strong cooling chamber 14; Figure 8 As shown, air outlets 381 are respectively provided on both sides of the upper end of the partition 38, and a cylinder 382 is installed in the air outlet. Limiting rings are respectively provided at both ends of the cylinder 382, and a mesh plate 383 is installed in the cylinder 382 to further filter the air.

[0046] When in use, the exhaust fan 41 is started to draw the hot air generated in the weak cooling chamber 15 into the strong cooling chamber 14, so that the hot air in the weak cooling chamber 15 is drawn into the strong cooling chamber 14 for mixing, and the mixed air enters the weak cooling chamber 15 through the air outlet 381, so as to reduce the temperature difference between the weak cooling chamber 15 and the strong cooling chamber 14, prevent the generation of water vapor, and thus protect the battery pack 1.

[0047] Specifically, such as Figure 4 、 Figure 11-12 As shown, the frame 20 also includes a collecting pipe 22 and a sealing strip 23. A sealing groove 217 parallel to the guide groove 213 is provided on the side wall of the guide groove 213 facing the inner side of the shelf 21. The bottom of the sealing strip 23 is fixedly installed in the sealing groove 217, and the top of the sealing strip 23 protrudes upward from the top surface of the shelf 21 by a certain height. The sealing strip 23 is made of elastic material. When the cavity plate 35 is placed on the corresponding shelf 21, the bottom surfaces of both ends of the cavity plate 35 abut against the sealing strip 23. Under the action of the gravity of the cavity plate 35, the cavity plate 35 squeezes the sealing strip 23 downward, so that the sealing strip 23 separates the two ends of the bottom surface of the cavity plate 35 from the middle of the bottom of the cavity plate 35. When leakage occurs at the connection between the output end of the cavity plate 35 and the inlet pipe 351 and / or the connection between the output end of the cavity plate 35 and the outflow pipe 352, the coolant can enter the guide groove 213 to prevent the leaked coolant from entering the middle of the bottom surface of the cavity plate 35 and flowing along the middle of the bottom surface of the cavity plate 35 to the battery pack 1 on the next layer of cavity plate 35. In addition, the weak cold cavity 15 can also be kept dry.

[0048] The bottom surface of the guide groove 213 is provided with a slope 218, which is inclined downward in the direction of the limit bar 212 so that the coolant entering the guide groove 213 can be quickly discharged to prevent the generation of water vapor. The end of the guide groove 213 facing the limit bar 212 is provided with a conduit 219, and the conduit 219 is arranged corresponding to the lowest end of the slope 218.

[0049] The collecting pipes 22 are vertically arranged on the side of the distribution trajectory of the shelf 21 toward the shell 10, and two groups are symmetrically arranged. The conduits 219 on the same side are connected to the input end of a corresponding collecting pipe 22. The lower ends of the two collecting pipes 22 pass through the same horizontal pipe, and the middle part of the horizontal pipe is connected to the inlet pipe 221 through a three-way joint. The output end of the inlet pipe 221 is connected to the output end of the liquid outlet pipe 37. In order to prevent the inlet pipe 221 from flowing back, a one-way valve is provided between the inlet pipe 221 and the liquid outlet pipe 37.

[0050] Preferably, a sensor is provided between the inlet pipe 221 and the three-way connector to detect whether there is flowing coolant in the inlet pipe 221. If so, a signal is sent to the upper machine position to facilitate timely maintenance by the operator.

[0051] like Figure 13 As shown, a diverter is provided in the cavity plate 35 for diverting the coolant entering the cavity plate 35 so that the coolant flows evenly in the cavity plate 35. The diverter includes a baffle 353, which is arranged along the width direction of the cavity plate 35. Liquid separation holes 354 are arranged along the length direction of the baffle 353, and the liquid separation holes 354 located in the middle of the baffle 353 have the smallest diameter. The diameters of the liquid separation holes 354 on both sides increase synchronously toward the two sides of the baffle 353 to reduce the error between the coolant on both sides of the cavity plate 35 and the coolant in the middle of the cavity plate 35 due to backward entry, thereby improving the heat dissipation effect.

[0052] A diverter plate 355 is arrayed along the length direction of the baffle plate 353. One end of the diverter plate 355 is perpendicular to the baffle plate 353 so that multiple flow channels are formed in the cavity plate 35. The other end of the diverter plate 355 is at a predetermined distance from the outflow end of the cavity plate 35 for the coolant to flow in and out along the cavity plate 35.

[0053] The above design is to allow the coolant entering the cavity plate 35 to evenly cover the cavity plate 35 to improve the heat dissipation effect.

[0054] Specific heat dissipation process: The refrigerator 31 is started, so that the coolant enters the input end of the liquid inlet pipe 32 along the output end of the refrigerator 31, and then enters the input end of the serpentine pipe 33 from the output end of the liquid inlet pipe 32. The output end of the serpentine pipe 33 flows into the extension pipe 331, so that the coolant enters the weak cold cavity 15, and enters the shunt pipe 34 along the output end of the extension pipe 331. The output ends of the shunt pipe 34 flow into the corresponding inlet pipes 351 respectively, and then the inlet pipe 351 flows the output end of the coolant into the corresponding cavity plate 35. Under the action of the baffle 353, the coolant is temporarily stored and diverted between the baffle 353 and the input end of the cavity plate 35, so that the coolant enters the corresponding flow channels through the liquid separation hole 354, so that the coolant in the cavity plate 35 is evenly distributed, so that the cooling effect of each part of the cavity plate 35 is roughly the same, thereby taking away the heat generated by the battery pack 1 and improving the heat dissipation effect.

[0055] The coolant flows into the outflow pipe 352 through the output end of the cavity plate 35 , flows into the manifold 36 through the outflow pipe 352 , and flows into the refrigerator 31 through the output end of the manifold 36 .

[0056] In order to increase the flow rate of the coolant and speed up the cooling process, a pump may be provided at the output end of the refrigerator 31 .

[0057] While the refrigerator 31 is working, the exhaust fan 41 is started, so that the air in the weak cooling chamber 15 passes through the filter plate 12 and enters through the through holes on the inner wall panel of the door panel 11. Then, it enters the air inlet end of the exhaust fan 41 through the connecting hose 42. The exhaust fan 41 draws the incoming air into the strong cooling chamber 14 for mixing, and then flows back into the weak cooling chamber 15 through the air outlet 381. This design can heat up the air in the strong cooling chamber 14, avoid the large temperature difference from generating a large amount of water vapor outside the serpentine tube 33, and at the same time play the role of reducing the temperature in the weak cooling chamber 15.

[0058] The design of the filter plate 12 can adsorb impurities in the air, and the filter plate 12 is connected by bonding, which is convenient for disassembly and cleaning.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to be the only one or to limit the present invention. It should be understood by those skilled in the art that various changes or equivalent replacements made to the present invention without departing from the scope of the present invention are within the scope of protection of the present invention.
