[0018] The utility model provides a high-efficiency dual-channel immersion battery comprehensive thermal management mechanism: comprising a base 10, an inlet and outlet cover plate 20, an upper cover plate 30, a partition plate 40, a battery 50, a liquid inlet pipe 60, a liquid outlet pipe 70 and a coolant, wherein the upper cover plate 30 is snap-fitted with the base 10, the inlet and outlet cover plate 20 is respectively connected with the upper cover plate 30 and the base 10, the upper cover plate 30, the inlet and outlet cover plate 20 and the inlet and outlet cover plate 20 enclose a cavity, the inlet and outlet cover plate 20 has a mounting groove 21, the partition plate 40 is arranged in the cavity, and one side of the partition plate 40 is embedded in the mounting groove 21, the liquid inlet pipe 60 and the liquid outlet pipe 70 are respectively fixedly connected with the inlet and outlet cover plate 20, and the liquid inlet pipe 60 and the liquid outlet pipe 70 are both connected with the cavity, the partition plate 40 has a plurality of placement holes 41, each of the placement holes 41 is provided with the battery 50, and the cavity is filled with the coolant.

[0019] In this embodiment, the battery 50 is installed in the placement hole 41 corresponding to the partition 40, and there is a clearance fit between the battery 50 and the placement hole 41, and the clearance fit size is controlled at 1mm~2mm to ensure the purpose of fixing the position of the battery 50 while not damaging the battery 50. The battery 50 and the partition 40 are assembled together in the base 10, and the upper cover plate 30 is installed above the battery 50. The upper cover plate 30 and the base 10 are preliminarily connected together by preset buckles. The upper cover plate 30, the base 10 and the partition 40 are inserted into the interior of the inlet and outlet cover plate 20, and the mounting groove 21 restricts the partition 40. Finally, the base 10, the upper cover plate 30 and the inlet and outlet cover plate 20 are welded together; the liquid inlet pipe 60 adds the coolant, and the liquid outlet pipe 70 discharges the coolant, realizing dual-channel addition and discharge of the coolant, thereby improving the heat dissipation and heating effect of the battery 50.

[0020] Furthermore, the cavity includes an upper cooling cavity 11 and a lower cooling cavity 12 .

[0021] Furthermore, the liquid inlet pipe 60 is connected to the lower cooling chamber 12 , and the liquid outlet pipe 70 is connected to the upper cooling chamber 11 .

[0022] Furthermore, the coolant is filled into the lower cooling cavity 12 from the liquid inlet pipe 60 .

[0023] In this embodiment, the heated or cooled coolant enters the lower cooling chamber 12 through the liquid inlet pipe 60, and performs heat exchange with the battery 50 in the lower half. A suitable interval is left between each row of the batteries 50 to ensure sufficient heat exchange of the batteries 50 while controlling the appropriate coolant flow resistance. According to the different energy densities of the batteries 50, the interval is usually about 5.5 mm. After the coolant fills the lower cooling chamber 12, it flows to the top of the upper cooling chamber 11 through the gap between the partition 40 and the base 10 (a gap of about 10 mm is reserved between the partition 40 and the base 10), and performs heat exchange with the battery 50 in the upper half again. Finally, the coolant flows out through the liquid outlet pipe 70 to complete the entire heat exchange process. During the flow of the coolant, according to the needs of the battery 50, the heat generated by the battery 50 is taken away, or the heat is transferred to the battery 50 to achieve comprehensive thermal management of the battery 50.
