Description

Technical Field

[0001] The utility model relates to the technical field of power energy storage, and particularly relates to a novel brazing structure of an energy storage liquid cooling plate. Background Art

[0002] With the rapid development of the energy storage industry, the heat dissipation requirement for battery cells is getting higher and higher, and a new type of liquid cooling plate has emerged accordingly.

[0003] At present, the energy storage liquid cooling plates on the market are divided into: extruded profile type, stamping brazing flat type, and stamping brazing basin type. Their disadvantages are respectively: the even temperature performance of the energy storage extruded profile liquid cooling plate is poor, the cost is high, the quality is heavy, etc.; the disadvantages of the stamping brazing flat type are: poor sealing performance, low structural strength, easy deformation, etc.; the above-mentioned energy storage liquid cooling plates cannot meet the use requirements of the industry.

[0004] Therefore, we propose a novel brazing structure of an energy storage liquid cooling plate. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a novel brazing structure of an energy storage liquid cooling plate. The basin-shaped upper cover plate and the basin-shaped flow channel plate are brazed and sealed, thereby improving the sealing performance of the liquid cooling plate. There are gaps left in the vertical bending areas of the basin-shaped upper cover plate and the basin-shaped flow channel plate, which can improve the brazing yield rate of the liquid cooling plate; a reinforcing rib is provided at the bottom end of the basin-shaped flow channel plate, thereby improving the strength and stiffness of the basin-shaped flow channel plate, greatly controlling the brazing deformation and the overall welding strength of the liquid cooling plate, and effectively solving the problems in the background art.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A novel brazing structure of an energy storage liquid cooling plate, including a basin-shaped upper cover plate and a basin-shaped flow channel plate. The basin-shaped flow channel plate is a horizontally arranged rectangular plate-like structure. The upper end surface of the basin-shaped flow channel plate is buckled with a basin-shaped upper cover plate. A groove is provided in the middle of the upper end surface of the basin-shaped upper cover plate. An installation hole for installing a water nozzle is provided on the inner wall of one end of the groove.

[0008] A heat conduction component is installed in the groove. The heat conduction component includes a buckle plate, a bolt, a heat conduction plate, and a heat sink.

[0009] By adopting the above technical solution, the upper end surface of the basin-shaped flow channel plate is buckled with the basin-shaped upper cover plate, and the basin-shaped upper cover plate and the basin-shaped flow channel plate are stacked together with gaps left around, which can effectively solve the problems of air entrapment and the assembly of the basin-shaped upper cover plate and the basin-shaped flow channel plate during the brazing process, and improve the brazing yield rate of the overall liquid cooling plate;

[0010] Compared with the flat plate type, the basin-shaped structure adopted by the 2.2-meter-long liquid cooling plate can better control the deformation and distortion during the brazing process, and can better control the distortion and deformation of the liquid cooling plate during the assembly process;

[0011] The basin-shaped upper cover plate and basin-shaped runner plate are both formed by an integrated mold, and the overall sealing performance is effectively guaranteed.

[0012] Specifically, the water nozzles are provided in two groups in parallel with each other.

[0013] Specifically, the mounting holes are communicated with the assembly holes, and the mounting holes and the assembly holes are each provided with two groups.

[0014] Specifically, the heat conducting plate is a horizontally arranged rectangular plate-shaped structure, and the heat conducting plate is fixedly connected to the inner wall of the bottom end of the groove by bolts.

[0015] Specifically, the bottom end of the buckle plate is fixedly connected to the upper end surface of the heat conducting plate, and a heat conducting cavity is provided in the buckle plate.

[0016] Specifically, a plurality of heat sinks are provided in parallel with each other, the heat sinks are located in the heat conduction cavity, and the bottom ends of the heat sinks are vertically connected to the upper end surface of the heat conduction plate.
