[0036] Preferably, mounting holes are provided on the first mounting surface 6 and the second mounting surface 7 , and the mounting holes are used for inserting cable ties, and the cable ties are used for connecting the liquid cooling tubes 5 .

[0037] Specifically, the mounting hole may be a φ6.5 hole, and the cable tie may be a fir-tree type cable tie, which is used to bundle the liquid cooling tube 5 to fix the liquid cooling tube 5 and prevent the aluminum alloy liquid cooling plate of the battery module 2 from rubbing against the liquid cooling tube 5 during movement of the vehicle.

[0038] Preferably, the first fixing bracket 3 and the second fixing bracket 4 are both sheet metal bending parts.
