The embodiment provides a battery cell module, including a plurality of battery cell rows and liquid cooling subassembly. Every electric core row includes a plurality of electric cores, and electric core can produce the heat at the during operation, avoids electric core because of the too high thermal runaway of heat, comes to electric core cooling through setting up the liquid cooling subassembly. Specifically, the liquid cooling subassembly is provided with the liquid cooling board including two at least liquid cooling boards that are linked together between two adjacent electric core rows, is provided with the liquid cooling passageway in the liquid cooling board for let in heat transfer medium, the liquid cooling board can contact with two adjacent rows of electric cores, in order to reduce the temperature of electric core.
In order to connect the plurality of liquid cooling plates and simplify the structure of the liquid cooling assembly, as shown in fig. 1 and fig. 2, the liquid cooling assembly further comprises a connecting pipe 20, the liquid cooling plates comprise a wavy plate body, an end 11 positioned at the end of the plate body and a pipe joint 12 arranged on the end 11, the plate body is of a hollow structure, a communicating channel 111 is arranged in the end 11, the communicating channel 111 is respectively communicated with the inside of the plate body and the inside of the pipe joint 12, and the connecting pipe 20 is used for connecting the pipe joints 12 on two adjacent liquid cooling plates so as to communicate the two adjacent liquid cooling plates.
In the prior art, in order to ensure the sealing performance of the liquid cooling assembly and avoid the leakage of the heat exchange medium, a plastic sealing ring is sleeved outside the pipe joint 12, and after the connecting pipe 20 is connected with the pipe joint 12, the assembly gap between the pipe joint 12 and the connecting pipe 20 is sealed through the plastic sealing ring. However, the linear sealing is formed by adopting the plastic sealing ring, and the sealing effect is poor; and because of electric core size is little, and the distance between two adjacent liquid cooling boards is little, and current connecting pipe 20 is the nylon connecting pipe, and the material is harder, and the operation is comparatively difficult when leading to nylon connecting pipe and coupling 12 to assemble, leads to the plastic sealing washer skew moreover easily, and then influences sealed effect.
In order to solve the above problem, in the present embodiment, the connection tube 20 includes a tube body 21 and an elastic layer 22 disposed on an inner wall of the tube body 21, and the tube joint 12 is inserted into the tube body 21 and abuts against the elastic layer 22.
