[0002] The liquid cooling plate is the core component of the battery liquid cooling system, which can be used in the distribution box to dissipate heat for the batteries in the distribution box to ensure the normal operation of the distribution box; the existing liquid cooling plate, as described in the patent document of Chinese Patent Publication No. CN204090418U, generally circulates the coolant in the flow channel of the liquid cooling plate to take away the heat from the surface of the liquid cooling plate, thereby achieving the effect of dissipating heat from the batteries on its surface.

[0003] In the existing liquid cooling plate, the actual heat exchange efficiency achieved when the coolant flows in the liquid cooling plate is not high, so a liquid cooling plate with higher heat exchange efficiency is needed. Utility Model Content

[0004] The utility model aims to provide a technical solution of a liquid cooling plate structure to address the deficiencies in the prior art, which can improve the heat transfer efficiency of the liquid cooling plate by increasing the bends of the flow channel and disturbing the coolant flowing in the flow channel.

The surface of the liquid-cooled lower plate is connected with a plurality of heat dissipation ribs, and the heat dissipation ribs are located between the liquid-cooled upper plate and the liquid-cooled lower plate. The heat dissipation ribs are spaced apart from each other to form a flow channel between the liquid-cooled upper plate and the liquid-cooled lower plate. The flow channel is used to guide the flow direction of the coolant entering the liquid-cooled bottom plate, and the flow channel includes a plurality of bends. The surface of the liquid-cooled lower plate is evenly laid with staggered fins along the flow channel, and the staggered fins are used to disturb the coolant flowing in the flow channel.

[0010] By adopting the above technical solution, a number of heat dissipation ribs form a flow channel between the liquid-cooled upper plate and the liquid-cooled lower plate. The flow channel has multiple bends, and the coolant flowing therein can more effectively take away the temperature of the surface of the liquid-cooled bottom plate; staggered fins are evenly laid along the flow channel on the surface of the liquid-cooled lower plate, which can disturb the coolant flowing therein, enhance the turbulent heat transfer process of the coolant, and thereby achieve the purpose of improving the heat transfer efficiency of the liquid-cooled bottom plate.

[0011] Furthermore, the fin thickness of the staggered fin is 0.2 mm, and the staggered tooth height of the staggered fin is 5 mm.

[0012] Furthermore, a boss structure is formed on the surface of the liquid-cooled lower plate, the boss structure is formed on both sides of the surface of the liquid-cooled lower plate, and the upper surface of the boss structure is flush with the upper surface of the heat dissipation ribs.

[0013] Furthermore, one end of the heat dissipation rib is clamped with the boss structure through a mortise and tenon structure.

[0014] Furthermore, the boss structure is formed with a liquid inlet channel and a liquid outlet channel, both of which are connected to the flow channel, and both of which are narrower than the flow channel.

[0015] Furthermore, arc-shaped expansion structures are formed at the connections between the liquid inlet channel, the liquid outlet channel and the flow channel.

[0016] Furthermore, it also includes a battery frame, which is fixedly connected to the surface of the liquid-cooled base plate, and the battery frame can fix the battery placed on the surface of the liquid-cooled base plate.

[0019] Furthermore, an insulating layer is formed on the surface of the liquid cooling base plate.

[0020] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0021] 1. The utility model can improve the heat transfer efficiency of the liquid cooling base plate by arranging a plurality of bends in the flow channel and cooperating with staggered fins laid in the flow channel;

[0022] 2. The heat dissipation rib and the boss structure of the utility model are further connected by the mortise and tenon structure, thereby improving the connection stability of the heat dissipation rib in the liquid cooling base plate;

[0023] 3. The liquid inlet channel and the liquid outlet channel formed in the boss structure in the utility model are narrower than the flow channel, which has the effect of slowing down the coolant. By reducing the flow rate of the coolant, the efficiency of heat exchange of the liquid cooling base plate can be further improved;

[0042] The liquid cooling base plate 1 is used to dissipate heat from the batteries placed thereon.

[0043] Furthermore, the liquid cooling bottom plate 1 includes a liquid cooling upper plate 11 and a liquid cooling lower plate 12. The surface of the liquid cooling lower plate 12 is connected with a plurality of heat dissipation ribs 13. The heat dissipation ribs 13 are located between the liquid cooling upper plate 11 and the liquid cooling lower plate 12. Figure 4 , Figure 5 As shown;

[0044] The heat dissipation ribs 13 are spaced apart from each other, and a flow channel 14 is formed between the liquid cooling upper plate 11 and the liquid cooling lower plate 12. Figure 4-Figure 6 As shown;

[0045] The flow channel 14 is used to guide the flow direction of the cooling liquid entering the liquid cooling base plate 1;

[0046] The flow channel 14 is designed with multiple bends, such as Figure 6 As shown;

[0047] The multi-bend design of the flow channel 14 can increase the flow distance of the coolant therein, thereby improving the heat transfer efficiency of the liquid cooling base plate 1.

[0048] The surface of the liquid-cooled lower plate 12 is evenly laid with staggered fins along the flow channel 14. The staggered fins are used to disturb the coolant flowing in the flow channel 14, which can strengthen the turbulent heat transfer process of the coolant, thereby achieving the purpose of improving the heat transfer efficiency of the liquid-cooled bottom plate 1;

[0049] In this embodiment, the fin thickness of the staggered fin is 0.2 mm, and the staggered height of the staggered fin is 5 mm.

[0050] The surface of the liquid cooling lower plate 12 is formed with a boss structure, and the boss structure is formed on both sides of the surface of the liquid cooling lower plate 12. Figure 5 As shown;

[0051] The upper surface of the boss structure is flush with the upper surface of the heat dissipation rib 13;

[0052] The inner wall of the boss structure is a part of the flow channel 14, and the boss structure forms a barrier to the coolant in the flow channel 14 on both sides of the liquid-cooled lower plate 12;

[0053] Furthermore, the boss structure includes a first boss 15 and a second boss 16. Figure 5 , Figure 6 As shown;

[0054] In this embodiment, the heat dissipation ribs 13 are welded to the surface of the liquid cooling lower plate 12;

[0059] The boss structure is formed with a liquid inlet channel 17 and a liquid outlet channel 18, and the liquid inlet channel 17 and the liquid outlet channel 18 are both formed on the first boss 15 and communicated with the flow channel 14. Figure 5 , Figure 6 As shown;

[0060] The liquid inlet channel 17 and the liquid outlet channel 18 are narrower than the flow channel 14. Figure 5 , Figure 6 As shown;

[0062] The connection between the liquid inlet channel 17, the liquid outlet channel 18 and the flow channel 14 forms an arc-shaped expansion structure 19, such as Figure 5 , Figure 6 As shown;

[0063] The arc-shaped expansion structure 19 can make the coolant flow more smoothly, reduce the resistance of the coolant at the corners, and thus improve the flow efficiency of the coolant.

[0064] The liquid cooling base plate 1 includes a water inlet 4 and a water outlet 5. Figure 1 , Figure 2 As shown;

[0065] The water inlet nozzle 4 and the water outlet nozzle 5 penetrate the liquid cooling upper plate 11 and are connected to the upper surface of the liquid cooling bottom plate 1;

[0066] The water inlet nozzle 4 and the water outlet nozzle 5 correspond to the liquid inlet channel 17 and the liquid outlet channel 18. Figure 5 , Figure 6 As shown;

[0067] The water inlet nozzle 4 is connected to the liquid inlet channel 17;

[0068] The water outlet nozzle 5 is connected to the liquid outlet channel 18;

[0082] The battery is placed on the surface of the liquid-cooled base plate 1 for heat dissipation. The battery is fixed in place with the battery card slot 29, which can improve the stability of the connection between the battery and the liquid-cooled base plate 1 and reduce the possibility of shaking or displacement of the battery during operation. At the same time, after the battery and the liquid-cooled base plate 1 are correctly aligned and fixed, they are assembled together in the distribution box, which can simplify the assembly process and avoid errors or damage that may occur during the separate assembly process.

[0083] The battery frame 2 includes a fifth side tube 25, which is connected to the battery frame 2. Figure 5 As shown, a recessed structure 26 is formed between the fifth side tube 25 and the fourth side tube 24;
