Furthermore, the cover body and the plate body are connected to form a cavity inside, a plurality of vent holes are uniformly formed in the plate body, and the vent holes penetrate through the retainer to correspond to gaps between the small batteries.

Furthermore, a through hole is formed in the center of the cover body, the through hole is communicated with the cavity, and an air pipe is arranged at the through hole.

Furthermore, an air inlet hole and an air outlet hole are formed in the box body, the air inlet hole is used for allowing air pipes at two ends of the small batteries to penetrate through, and the air inlet hole, the air pipes, the cavity between the cover body and the plate body, the through holes in the plate body, the gaps between the small batteries and the air outlet hole are combined to form a ventilation pipeline.

The utility model discloses following beneficial effect has:

this lithium cell is provided with ventilation pipe way in that the group battery is inside, can effectually dispel the heat to group battery inside to can guarantee through the position that sets up the tuber pipe that it is more to get into the inside amount of wind of group battery, and the amount of wind of group battery outer wall still less, guarantees the inside radiating quality of group battery.

The utility model discloses in, be convenient for fix the microbattery and evenly distributed through setting up the holder to the air of being convenient for passes and dispels the heat.

Through setting up the through-hole position of seting up on the through-hole of seting up on the plate body and the lid and guaranteeing to get into the inside amount of wind of group battery more, the amount of wind of group battery outer wall still less, and then guarantees the radiating quality in group battery inside.
