Description

Technical Field

[0001] The utility model relates to the technical field of liquid cooling plates, in particular to a liquid cooling plate cut-out welding structure. Background Art

[0002] As an important component of the battery thermal management system, the liquid cooling plate has the main function of circulating the coolant in the channel inside the plate to take away the heat generated by the battery, thereby achieving effective heat exchange and temperature control. The design and manufacturing process of the liquid cooling plate directly affects the efficiency and reliability of the thermal management system. The battery liquid cooling plate of the prior art mainly includes three types according to different process routes: extruded aluminum profiles, stamping brazing and die casting. For extruded aluminum profiles, the main component flow channel plate is usually connected by two to four narrow flow channel plates. The connection effect of the flow channel plate has a direct impact on the sealing, structural strength, vibration performance and weather resistance of the battery liquid cooling plate.

[0003] At present, liquid cooling plates are generally welded with mortise and tenon welding structures, and the mortise and tenon welding structure requires precise processing to ensure the fit between the tenon and the mortise, which usually requires more complex processing technology and equipment, increasing the manufacturing cost. At the same time, the mortise and tenon structure may require higher precision and skills during assembly, because the tenon and the mortise need to fit very tightly, which makes assembly difficult. In addition, if the mortise and tenon structure does not fit properly, tiny gaps may be generated at the joints, affecting the sealing performance of the liquid cooling plate and reducing the use effect of this structure. Based on this, we propose a liquid cooling plate cut-edge welding structure. Utility Model Content

[0006] Preferably, the cut and welded structure forms a hollow portion.

[0007] Preferably, arc chamfers are provided at the connection points between the flow channel plate 1, the flow channel plate 2 and the hook plate.

[0017] like Figure 1 As shown:

[0018] A liquid cooling plate cut and welded structure comprises a flow channel plate 1 and a flow channel plate 2 which are distributed on the left and right sides.

[0019] In the present embodiment: In order to solve the technical problems existing in the prior art, as disclosed in the background technology above, "the current liquid cooling plate is generally welded with a mortise and tenon welding structure, and the mortise and tenon welding structure requires precise processing to ensure the fit between the tenon and the mortise, which usually requires more complex processing technology and equipment, increasing the manufacturing cost, and the mortise and tenon structure may require higher precision and skills during assembly, because the tenon and the mortise need to fit very tightly, which makes assembly difficult, and improper mortise and tenon structure cooperation may produce tiny gaps at the joints, affecting the sealing performance of the liquid cooling plate and reducing the use effect of this structure."

[0020] More specifically:

[0021] A hook plate 3 is fixed on one side of the flow plate 1 and the flow plate 2 that are close to each other, and the two groups of hook plates 3 are separated from each other.

The two groups of hook plates 3 are tightly fitted with the inner walls of the flow plate 1 and the flow plate 2, respectively, and the upper and lower welding points of the flow plate 1 and the flow plate 2 are staggered and are not on the same vertical plane.

[0022] In the present embodiment: when the flow channel plate 1 and the flow channel plate 2 are installed by matching with the hook plate 3, the two groups of hook plates 3 are separated from each other at the same time, and the flow channel plate 1 and the flow channel plate 2 are engaged with each other by the two groups of hook plates 3 to form a cut-and-weld structure, so that the cut-and-weld structure is usually easier to process than the mortise and tenon structure, because it does not require precise matching of the tenon and the mortise, reducing the processing difficulty and cost, and the cut-and-weld structure is usually more convenient than the mortise and tenon structure during assembly, because it does not require precise alignment of the tenon and the mortise, simplifying the assembly process, and the cut-and-weld structure can provide good sealing performance, prevent leakage of coolant, reduce stress concentration at the connection, and improve the stability and life of the structure. The upper and lower welding points of the flow channel plate 1 and the flow channel plate 2 are staggered and not on the same vertical plane, thereby reducing the situation where the upper and lower joints are subjected to stress at the same time, so that a stronger mechanical structure strength is generated between the flow channel plate 1 and the flow channel plate 2.

[0024] In an optional embodiment, the cut and welded structure forms a hollow portion 6 .

[0025] In this embodiment, the cut and welded structure forms a hollow portion 6, which can reduce the use of materials while ensuring strength, helping to reduce the overall weight and reduce costs.
