Description

Technical Field

[0001] The utility model relates to the technical field of welding jigs, and specifically relates to an immersion liquid cooling solution. Background Art

[0002] In the current field of battery thermal management, liquid cooling plates, as an effective heat dissipation solution, are widely used in the heat dissipation process of battery cells. However, the existing liquid cooling plate solutions mainly rely on the bottom contact surface for heat dissipation, and this design method has obvious limitations. Due to the difference in heat dissipation conditions between the top and bottom of the battery cell, there is a large temperature difference between them. This temperature difference not only affects the overall heat dissipation effect of the battery cell, but also reduces the heat transfer efficiency between the battery cell and the liquid cooling plate. Especially in the scenario where the battery cell needs to discharge at high power, the problems of uneven heat dissipation and low heat transfer efficiency are particularly prominent and cannot meet the stringent requirements of high-power discharge for heat dissipation. In addition, there are potential safety risks during the installation and use of the battery cell. If the battery cell is installed improperly or abnormal situations occur during use, such as overcurrent, overvoltage or short circuit, etc., it may trigger safety accidents such as the battery cell catching fire. This will not only damage the battery system, but also pose a serious threat to personal safety. Content of the Utility Model

A flow channel is opened inside the cold plate. A sheet metal plate is fixedly connected to the side wall of the cold plate. Two water inlets and outlets are symmetrically installed on the side wall of the sheet metal plate away from the cold plate, and the water inlets and outlets are communicated with the flow channel. The other side wall and the front and rear walls of the sheet metal plate are fixedly connected with L-shaped profile plates. Multiple L-shaped profile plates are fixedly connected to each other, and multiple L-shaped profile plates form a U shape. The multiple L-shaped profile plates and the sheet metal plate have the same height. The sheet metal plate and the multiple L-shaped profile plates form a square frame. A cavity is formed between the sheet metal plate and the multiple L-shaped profile plates. Multiple rivet nuts are equidistantly arranged on the upper surfaces of the multiple L-shaped profile plates and the sheet metal plate. The upper cover plate is fixedly connected to the tops of the L-shaped profile plates and the sheet metal plate through the rivet nuts. An opening is provided at the top of the upper cover plate, and a liquid filling port is provided on the side wall of the upper cover plate. The liquid filling port is communicated with the cavity.

[0016] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the utility model. Embodiment

[0017] As Figures 1-3As shown in the figure, an embodiment of the present utility model provides an immersion liquid cooling solution, which includes a cold plate 1 and an upper cover plate 8. A flow channel 2 is provided inside the cold plate 1. A sheet metal plate 3 is fixedly connected to the side wall of the cold plate 1. Two water inlets and outlets 4 are symmetrically installed on the side wall of the sheet metal plate 3 away from the cold plate 1. The water inlets and outlets 4 are communicated with the flow channel 2. The other side wall and the front and rear walls of the sheet metal plate 3 are fixedly connected with L-shaped profile plates 5. The plurality of L-shaped profile plates 5 are fixedly connected to each other. The plurality of L-shaped profile plates 5 form a U shape. The plurality of L-shaped profile plates 5 and the sheet metal plate 3 have the same height. The sheet metal plate 3 and the plurality of L-shaped profile plates 5 form a square frame. A cavity 7 is formed between the sheet metal plate 3 and the plurality of L-shaped profile plates 5. A plurality of rivet nuts 6 are equidistantly arranged on the upper surfaces of the plurality of L-shaped profile plates 5 and the sheet metal plate 3. The upper cover plate 8 is fixedly connected to the tops of the L-shaped profile plates 5 and the sheet metal plate 3 through the rivet nuts 6. An opening 9 is provided on the top of the upper cover plate 8. A liquid filling port 11 is provided on the side wall of the upper cover plate 8. The liquid filling port 11 is communicated with the cavity 7.

[0018] Two lifting holes 10 are symmetrically opened on the outer surface of the L-shaped profile plate 5. This design makes the whole liquid cooling solution more convenient for lifting and moving, and improves the convenience and flexibility of installation.

[0019] The fixing method between the plurality of L-shaped profile plates 5 is friction welding. Friction welding has the advantages of firm connection and good sealing performance, which can ensure the stable connection between the L-shaped profile plates 5 and improve the strength and stability of the overall structure.

[0020] An electric core and a coolant are placed inside the cavity 7. This design realizes the complete immersion cooling of the electric core, enables the electric core to be in full contact with the coolant, thereby improving the heat dissipation efficiency and heat exchange effect, and also helps to reduce the risk of the electric core catching fire and burning.

[0021] Working principle: When using the immersion liquid cooling solution, the battery cells are located in the cavity 7. The cooling liquid is added to the cavity 7 through the liquid filling port 11 on the upper cover plate 8, so that the battery cells in the cavity 7 are completely immersed in the cooling liquid, thereby achieving a balanced distribution of the temperatures at the bottom and top of the battery cells, significantly reducing the temperature difference between the two, and effectively improving the overall heat dissipation effect of the battery cells. At the same time, the cooling liquid flows into the flow channel 2 in the cold plate 1 from one of the water inlet and outlet 4, and the cooling liquid can flow through the cold plate 1 more smoothly and evenly. Then the cooling liquid flows out of the flow channel 2 from the other water inlet and outlet 4. Thus, the cooling liquid circulating in the flow channel 2 can improve the heat exchange efficiency of the cold plate 1. This enables this solution to withstand a greater heat exchange power of the battery cells and meet the heat dissipation requirements in high-power discharge scenarios. By completely immersing the battery cells in the cooling liquid, the utility model effectively avoids the risk of fire and combustion caused by improper installation or abnormal conditions of the battery cells, such as overcurrent, overvoltage, short circuit, etc., significantly improves the safety of the battery cells, and ensures the stable operation of the battery system. The opening 9 at the top of the upper cover plate 8 facilitates observing the state of the battery cells in the cavity 7. Two lifting holes 10 are symmetrically arranged on the outer surface of the L-shaped profile plate 5, making the entire liquid cooling solution more convenient for lifting and moving, and improving the convenience and flexibility of installation.

[0022] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
