[0044] The present invention is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0046] like Figure 1 As shown, the present invention provides a water-cooling plate, comprising a plurality of continuously arranged water-cooling parts 1, wherein adjacent water-cooling parts 1 are fixedly connected to form a square structure, and any water-cooling part 1 comprises:

[0047] The plate body 2 is a box structure with openings at both ends and a hollow interior;

[0048] Two side plates 3 are fixedly arranged at two ends of the plate body 2 and form a sealed water cooling cavity with the plate body 2. The two side plates 3 are respectively provided with a water inlet hole 5 and a water outlet hole 6 connected with the water cooling cavity. The water inlet hole 5 and the water outlet hole 6 are arranged diagonally.

[0049] A plurality of diverter plates 7 are arranged in parallel and at intervals in the water cooling chamber to divide the water cooling chamber into a plurality of diverter portions 8 that are interconnected, any diverter plate 7 is fixedly arranged along the length direction of the plate body 2, and both ends of the diverter plate 7 do not contact the two side plates 3 to form a water flow channel;

[0050] Two plug groups are respectively arranged on the two side plates 3 , and any plug group includes a plurality of plugs 4 , which are arranged at intervals along the width direction of the plate body 2 , and any plug 4 is fixedly arranged between the corresponding side plate 3 and the adjacent diverter plate 7 .

[0051] In the above technical scheme, the water-cooling plate is a part of the battery heat dissipation system, which mainly takes away the heat of the battery by the cooling water flowing inside the water-cooling plate, thereby realizing the heat dissipation effect on the battery. In the above technical scheme, the water-cooling plate is composed of a plurality of continuously arranged water-cooling parts 1, and a suitable number of water-cooling parts 1 can be selected according to the length of the battery to be dissipated, so as to match the length of the water-cooling plate with the length of the battery to be dissipated, and has high flexibility; any water-cooling part 1 is composed of a plate body 2 and two side plates 3, and a sealed water-cooling cavity is formed between the side plates 3 and the plate body 2, and a plurality of diverter plates 7 that are not in contact with the two side plates 3 are arranged in the water-cooling cavity to divide the water-cooling cavity into a plurality of mutually connected diverter parts 8, and the cooling water enters from the water inlet hole 5 set on one of the side plates 3, and flows in the plurality of diverter parts 8 to absorb the heat of the battery, and then flows from another Water flows out from the water outlet holes 6 arranged on the side panels 3 to achieve heat dissipation for the battery. In actual applications, since the vehicle has various operating conditions, the requirements for the output power of the battery under different conditions are different, and thus the heat generated by the battery during operation is different, and the heat dissipation requirements are also different. In order to meet the heat dissipation requirements of the battery under different conditions, a plurality of plugs 4 are respectively arranged on the two side panels 3 along their width directions, and the two ends of any plug 4 are respectively fixedly connected to the inner wall of the corresponding side panel 3 and the end of the adjacent diverter plate 7 to close the flow path between the end of the diverter plate 7 connected to the plug 4 and the side panel 3, thereby changing the flow path of the cooling water and the flow direction of the cooling water in the diverter portion 8 to adjust the heat dissipation effect of the water cooling portion 1 on the battery, wherein the number of the plugs 4 and the setting positions can be freely set according to the actual working conditions.

[0052] <Example 1>

[0053] like Figure 2 As shown, the number of plugs 4 on the two side plates 3 of this water-cooling part 1 is the same, and when the plugs 4 are set, they are set at intervals of a diverter plate 7, one end of any diverter plate 7 is fixedly connected to the plug 4, and the other end is not set with a plug 4, wherein one end of the diverter plate 7 close to the water inlet hole 5 is fixedly connected to the plug 4, that is, after the cooling water enters from the water inlet hole 5, it will only flow to the first diverter part 8 after passing through the obstruction of the plug 4, and will flow to the second diverter part 8 after passing through the plug 4 on the second diverter plate 7, and so on, the cooling water circulates in multiple diverter parts 8 in turn, and dissipates heat in turn at the corresponding battery positions on the water-cooling part 1.

[0054] <Example 2>

[0055] The number and position of the plugs 4 on the two side plates 3 of the water cooling unit 1 are as follows: Figure 3As shown, three adjacent diversion parts 8 are grouped together. After entering from the water inlet hole 5, the cooling water flows to the three adjacent diversion parts 8 at the same time. After reaching the next group of diversion parts 8, the cooling water flows to the next group of three diversion parts 8 at the same time. That is, the water cooling part 1 can dissipate heat for the positions of the corresponding batteries on the three adjacent diversion parts 8 at the same time, so the heat dissipation area is larger and the heat dissipation effect is better.

[0056] In another technical solution, the distances between the plugs 4 of two adjacent water cooling parts 1 are the same or different.

[0057] In the present technical scheme, the number and position of the plugs 4 on the water-cooling part 1 will affect its heat dissipation effect, that is, when the heat dissipation requirements of the battery positions corresponding to two adjacent water-cooling parts 1 on the water-cooling plate are the same, the number and position of the plugs 4 on the two adjacent water-cooling parts 1 are the same, that is, the heat dissipation effect of any part of the battery is the same; if the heat dissipation requirements of the battery positions corresponding to two adjacent water-cooling parts 1 on the water-cooling plate are different, the number and position of the plugs 4 on the adjacent water-cooling parts 1 can be set accordingly according to the heat dissipation requirements, so as to meet the heat dissipation requirements of various parts of the battery. The water-cooling plate described in the present application can combine and match the same water-cooling part 1 or different water-cooling parts 1 according to the heat dissipation requirements of each part of the battery to meet the actual working condition heat dissipation requirements, with high flexibility.

[0058] In another technical solution, Figure 4 , 5 As shown, the plate body 2 is a profile plate body, and the multiple plugs 4 and the two side plates 3 are made of the same material as the plate body 2; the cross-section of any diversion part 8 is a polygonal irregular shape; the cross-sectional shapes of the diversion parts 8 of two adjacent water-cooling parts 1 are the same or different.

[0059] In the present technical solution, the water flow resistance of the cooling water is affected by the cross-sectional shape of the flow channel, and the water flow resistance will affect the heat dissipation effect of the water-cooling part 1. Each component of the water-cooling part 1 is composed of profile parts. The profile can be made into an object with a certain geometric shape and a specific cross-sectional shape through a process, that is, the profile can be processed into a water-cooling part 1 with different cross-sectional shapes according to the heat dissipation requirements, that is, the cross-section of the diversion part 8 of the water-cooling part 1 is designed to be a polygonal irregular shape, thereby changing the heat dissipation effect of the water-cooling part 1, and the cross-sectional shape on adjacent water-cooling parts 1 can be selected according to the heat dissipation requirements of the battery. The water-cooling part 1 with the same cross-sectional shape or the water-cooling part 1 with different cross-sectional shapes is selected to improve the heat dissipation effect of the water-cooling plate. On the other hand, the profile is processed into the water-cooling part 1, and its mold cost is much lower than the cost of stamping molds or casting molds, and when developing water-cooling plates of different lengths, there is no need to redevelop tooling, and the development cost is low.

[0060] In another technical solution, Figure 6As shown, a positioning device is provided on the top of any plate body 2, which includes:

[0061] A connecting plate 11, which is a square structure and is detachably arranged on the top of the plate body 2;

[0062] A positioning block 12 is slidably arranged on the top of the connecting plate 11 along the width direction of the plate body 2, a guide plate 13 is arranged on the top of the positioning block 12 along the width direction of the plate body 2, a groove 14 is formed on the side wall of the guide plate 13 along the width direction of the plate body 2, and an elastic body is arranged on the inner surface of the groove 14;

[0063] Two positioning plates 15 are relatively horizontally fixedly arranged on the side wall of the guide plate 13 and located on the top and bottom surfaces of the groove 14. A threaded hole is opened on any positioning plate 15, and two ends of the screw 16 pass through the threaded holes on the two positioning plates 15 and are fixedly connected to the two positioning plates 15;

[0064] A positioning rod 17 is fixedly arranged at the end of the guide plate 13 along the width direction of the plate body 2 and extends out of the outside of the plate body 2. The positioning rod 17 and the groove 14 are located in the same horizontal plane, the diameter of the positioning rod 17 is the same as the diameter of the groove 14, and the outer side of the positioning rod 17 and the inner side of the threaded hole are located in the same vertical plane; the two adjacent water-cooling parts 1, the plate body 2 and the two side plates 3, and the two side plates 3 and the plug 4 are fixedly connected by stir friction welding.

[0065] In the present technical solution, adjacent water-cooling parts 1 are fixedly connected by means of friction stir welding. In order to avoid gaps and cracks during welding and affect the compressive resistance of the water-cooling plate, it is necessary to position the two adjacent water-cooling parts 1 in turn to ensure the accuracy of welding, that is, a positioning device is arranged on the top of any water-cooling part 1, and threaded holes can be opened around the water-cooling part plate body. The connecting plate 11 on the positioning device is bolted to the plate body 2 through the threaded holes. After welding is completed, the positioning device is removed from the water-cooling part 1 by loosening the bolts and disassembling the connecting plate 11. The threaded holes on the plate body 2 can facilitate the positioning and installation of the battery on the plate body 2. The positioning block 12 arranged on the top of the connecting plate 11 drives the guide plate 13 to move along the width direction of the plate body 2. The guide plate 13 is provided with a groove 14, and the space formed by the groove 14 and the screw 16 between the two threaded holes is the same as the diameter of the positioning rod 17. In the process of positioning the two water-cooling parts 1, the two water-cooling parts 1 are firstly abutted manually and the two positioning devices are driven to abut each other by sliding the positioning block 12. Until the positioning rod 17 on one of the positioning devices passes through the groove 14 on the other positioning device, the screw 16 passes through the threaded holes on the two positioning plates 15 and the positioning rod 17 is clamped between the groove 14 and the screw 16 through the nut, that is, the positioning is completed. The elastic body arranged in the groove 14 can prevent the end of the positioning rod 17 from contacting the groove 14 and causing damage to the groove 14. Then, the two water-cooling parts 1 are welded together by stir friction welding. Stir friction welding technology is a solid phase welding method. There is no burning of alloy elements during welding. Since its welding temperature is lower than the melting point of the material, it fundamentally eliminates welding defects such as pores, inclusions, element segregation, and solidification cracks caused by melting and solidification. The components of the water-cooling part are welded by this welding method, which can ensure the water tightness of the water-cooling part. The cooling water in the water-cooling part will not leak under high pressure to damage the battery. The adjacent water-cooling parts 1 are welded by this method, which can further ensure that there will be no gaps and cracks between the adjacent water-cooling parts 1, which will affect the pressure resistance of the water-cooling plate.

[0066] In another technical solution, Figure 8 As shown, the interior of any diversion portion 8 also includes:

[0067] An internal fluid channel is arranged along the length direction of the plate body 2, and the internal fluid channel includes a plurality of drainage grooves 10, the plurality of drainage grooves 10 are arranged relatively spaced apart and form an eight-shaped structure along the water flow direction, and any drainage groove 10 is fixedly connected to the inner bottom surface of the plate body 2;

[0068] Two first baffles 18, which are respectively arranged on the two diverter plates 7, one end of each first baffle 18 is fixedly connected to the inner side wall of the corresponding diverter plate 7, and the other end extends to the drainage groove 10 located at the head of the inner fluid channel;

[0069] A plurality of second baffles 19, which are respectively arranged on the two diverter plates 7, one end of any second baffle 19 is fixedly connected to the inner wall of the corresponding diverter plate 7, and the other end extends between two adjacent drainage grooves 10 and does not contact any drainage groove 10, and the lengths of the plurality of second baffles 19 along the water flow direction are successively reduced;

[0070] The first baffle plate 18 and the second baffle plate 19 are arranged in parallel and spaced apart and are respectively arranged at an acute angle to the inner side wall of the diverter plate 7 . The first baffle plate 18 and the second baffle plate 19 are both provided with a plurality of through holes through which water can flow.

[0071] In the present technical solution, after the cooling water enters the diversion part 8, supercooled boiling occurs to absorb the heat of the battery and generate bubbles. If the bubbles are too large, the diversion part 8 may be blocked, thereby causing the problem of excessively high local temperature of the water-cooled plate. The present application provides an internal fluid channel inside any diversion part 8, which is composed of a plurality of drainage grooves 10, and the plurality of drainage grooves 10 form an eight-shaped structure inside the diversion part 8 along the direction of water flow. The eight-shaped structure forms microchannels with gradually increasing diameters along the direction of water flow. When the cooling water supercools and boils to generate bubbles, the radially expanded microchannel formed by the drainage grooves 10 has an unbalanced surface tension between its tail and front. The surface tension can make the bubbles in the microchannel move along the direction of water flow and quickly leave the microchannel, thereby solving the problem of excessively high local temperature caused by individual bubbles being too large to be discharged from the water-cooling part 1. At the same time, a first baffle 18 is provided at the head of the internal fluid channel. The first baffle 18 is provided at an acute angle to the diversion plate 7, so that the cooling water enters the internal fluid channel through the drainage effect of the first baffle 18, while also preventing the previous water from The bubbles that are too large in the cold part 1 enter the section between the diverter plate 7 and the outside of the inner fluid channel; one end of the second baffle 19 is fixedly connected to the diverter plate 7, and the other end extends to between the two adjacent drainage grooves 10 to prevent the bubbles in the inner fluid channel from entering this section through the gap between the two drainage grooves 10, causing the excessive bubbles to block this section of the channel and cause the water-cooled part 1 to overheat locally. The through holes provided on the first baffle 18 and the second baffle 19 can make the cooling water temperature in the water-cooled part 1 evenly distributed, thereby improving Heat dissipation effect, wherein, since the cross-section of the water-cooling part 1 is a polygonal irregular shape, the drainage groove 10, the first baffle 18 and the second baffle 19 can be arranged accordingly according to the cross-sectional shape of the water-cooling part 1, and since the diverter parts 8 on both sides of the water-cooling part 1 are composed of the plate body 2 and the diverter plate 7, that is, one end of the first baffle 18 and the second baffle 19 located on both sides of the water-cooling part 1 and adjacent to the plate body 2 is fixedly connected to the inner side wall of the plate body 2, and the first baffle 18 and the second baffle 19 in other diverter parts 8 are respectively fixedly connected to the inner side wall of the diverter plate 7.

[0072] In another technical solution, Fig. 9As shown, any drainage groove 10 is a streamlined jujube-shaped protrusion structure, and its protrusion direction is the same as the water flow direction.

[0073] In the present technical solution, the drainage groove 10 is in the shape of a water drop, and the direction of its protrusion is the same as the direction of the water flow. The drainage groove 10 is designed in this shape. On the one hand, it can reduce the flow resistance of the cooling water and improve the heat dissipation efficiency of the water-cooling part 1. The reduction in flow resistance can further increase the flow speed of the bubbles in the cooling water, allowing them to quickly leave the diversion part 8. On the other hand, the streamlined structure of the jujube-shaped protrusion can reduce pressure loss while increasing the heat exchange area, and has good reliability.

[0074] In another technical solution, Figure 7 As shown, any diverter plate 7 is provided with a plurality of communication channels 9 at intervals along its length direction. Any communication channel 9 is a mesh structure and is located between two adjacent second baffles 19 . Any communication channel 9 connects two adjacent diverter portions 8 .

[0075] In the present technical solution, the mesh-shaped connecting channel 9 provided on the diverter plate 7, on the one hand, prevents excessively large bubbles from entering the area between the diverter plate 7 and the outside of the internal fluid channel through the connecting channel 9, and on the other hand, enables multiple water flow channels to be formed between two adjacent diverter portions 8, that is, the cooling water in each diverter portion 8 can be mixed with each other in a short time, the cooling water distribution is more even, and the cooling effect is good.

[0076] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented.
