[0007] According to one embodiment of the present invention, the middle plate is longer than the upper plate portion and the lower plate portion, and has a positioning protrusion inserted into the cover plate.

[0008] According to one embodiment of the present invention, the liquid inlet guide pipe and the liquid outlet guide pipe are both configured as flat tubes.

DETAILED DESCRIPTION

[0019] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0020] Please refer to Figure 1 and Figure 2 , Figure 1 This is a three-dimensional diagram of an automotive battery liquid cooling plate that uses a manifold and flow isolation chamber for double-layer flow diversion according to an embodiment of the present application; Figure 2This is a cross-sectional view of the installation of a flow confluence chamber for an automotive battery liquid cooling plate employing a double-layer flow diversion system with a manifold and a flow divider, according to an embodiment of the present application. As shown, the embodiment includes a flow confluence chamber 10 having an upper chamber 11 and a lower chamber 12, the upper chamber 11 being isolated from the lower chamber 12; a liquid inlet port 20 connecting one side of the upper chamber 11; a liquid inlet conduit 30 connecting the other side of the upper chamber 11; a liquid outlet port 40 connecting one side of the lower chamber 12; a liquid outlet conduit 50 connecting the other side of the lower chamber 12; and a flow confluence chamber 60 connecting the inlet conduit 30 and the outlet conduit 50, comprising a flow confluence chamber 61 with a partition 90 in the center.

[0021] In one embodiment of the present invention, the confluence chamber 10 has a double-layer design, comprising an upper chamber 11 and a lower chamber 12. The upper chamber 11 has a liquid inlet port 20, into which antifreeze flows through the liquid inlet valve. The opposite side has a liquid inlet guide tube 30, which guides the circulating antifreeze to achieve uniform heat dissipation of the battery within the vehicle and ultimately converges into the manifold chamber 60. The manifold chamber 61 within the manifold chamber 60 is blocked by the partition 90 and re-converges to the liquid outlet guide tube 50, ultimately flowing to the lower chamber 12 of the confluence chamber 10, where the antifreeze flows out through the liquid outlet port 40. As a result, the present invention completely staggers the liquid inlet and outlet, effectively ensuring uniform heat dissipation across the entire battery liquid cold plate and improving heat exchange efficiency.

[0022] Specifically, the confluence cavity 10 is composed of a cover plate 70 and a main plate 80, which are sealed at both ends. The main plate 80 is E-shaped and has a side plate portion 81, an upper plate portion 82 arranged on the side plate portion 81, a middle plate portion 83 and a lower plate portion 84; the upper plate portion 82 and the middle plate portion 83 correspond to the upper chamber 11, and the middle plate portion 83 and the lower plate portion 84 correspond to the lower chamber 12; the upper end of the cover plate 70 extends and is welded to the upper side of the upper plate portion 82, and the lower end extends and is welded to the lower side of the lower plate portion 84. In this embodiment, the main board 80 and the cover plate 70 are assembled to form the confluence cavity 10. Specifically, the main board 80 is isolated by the middle plate portion 83, and the upper plate portion 82 and the lower plate portion 84 at both ends complete the upper and lower blocking, and cooperate with the side plate portion 81 to present an E shape. The cover plate 70 is then used to complete the sealing of the opening on the other side. The seals at both ends can be limited by welding seals on the vehicle body, or additional sealing plates can be added. The present invention is not limited to this, and finally the upper chamber 11 and the lower chamber 12 of the confluence cavity 10 are formed, which has a simple structure and is easy to process.

[0023] Preferably, the middle plate portion 83 is longer than the upper plate portion 82 and the lower plate portion 84 and has a positioning protrusion 85 inserted into the cover plate 70 to increase the positioning of the assembly, thereby ensuring process accuracy and stability.

[0024] In addition, the liquid inlet interface 20 and the liquid outlet interface 40 are provided on the cover plate 70 ; the liquid inlet guide pipe 30 and the liquid outlet guide pipe 50 are provided on the side plate portion 81 , thereby increasing the ease of assembly.

[0025] In one embodiment, the liquid inlet guide pipe 30 and the liquid outlet guide pipe 50 are both configured as flat tubes, which save space, provide stable flow guidance, and have a wider heat dissipation area, thereby improving heat dissipation uniformity and efficiency.

[0026] Preferably, both ends of the flat tube are bent downwards, so as to facilitate the connection between the converging cavity 10 and the collecting cavity 60 and enhance the flowability. In addition, the flat tube is relatively upwards, which is convenient for installation.

[0027] In a preferred embodiment, two groups of liquid inlet guide tubes 30 and two groups of liquid outlet guide tubes 50 are respectively provided to improve heat dissipation efficiency. In other embodiments, three or four groups may be provided, but the present invention is not limited thereto.
