The cooling plate 3 has a heat dissipation channel 33 inside. A heat dissipation groove 12 is provided on one side of the mounting bracket body 1 to facilitate heat dissipation. During assembly, the workers place the battery cells 2 and the cooling plate 3 in the mounting groove 11 at the same time, which improves production efficiency and simplifies the structure. When cooling is required, coolant is introduced into the cooling plate 3. The coolant flows through the heat dissipation channel 33 and absorbs the heat from the surfaces of both ends of the battery cells 2. The remaining heat is dissipated through the heat dissipation groove 12, thereby improving the heat dissipation capacity of this utility model.

[0023] Furthermore, a connecting groove 13 is provided on the side of the fixing frame 1 away from the heat dissipation groove 12.

Furthermore, the liquid cooling unit is a commercially available existing technology.

[0024] Furthermore, the heat dissipation channel 33 is a serpentine channel, which increases the flow area of ​​the coolant and improves the heat dissipation effect of the cooling plate 3.

[0025] Furthermore, the fixing frame body 1 is detachably connected to a pull rod 4 on one side of the connecting groove 13. Both sides of the pull rod 4 are provided with connecting grooves 42, and both connecting grooves 42 are provided with through holes 41. The fixing frame body 1 is provided with a screw hole 14 that communicates with the through hole 41. The pull rod 4 and the fixing frame body 1 are connected by bolts passing through the through hole 41 and threadedly connected to the screw hole 14, which improves the convenience of connecting the pull rod 4 and reduces processing efficiency.

[0026] Furthermore, one side of the pull bar 4 is attached to the battery cell 2 and the cooling plate 3, and the pull bar 4 abuts against the battery cell 2 and the cooling plate 3, thereby limiting the position of the pull bar 4 on the battery cell 2 and the cooling plate 3 and improving the stability of the battery cell 2 and the cooling plate 3.

[0027] Furthermore, the mounting bracket body 1 is provided with an input / output interface 5 for electrically connecting several battery cells 2, thereby realizing the input and output of the battery cells 2.
