Also discloses a dust collector comprising the battery pack air suction cooling device.
Compared with the prior art, the utility model has the beneficial effects that:
(1) When the negative pressure fan is started, ambient air flow enters the battery ventilation channel from the air inlet, the air flow takes away heat of the battery pack through the battery ventilation channel, then the air flow passes through the communication channel and the negative pressure inlet and finally is discharged into the environment from the air outlet, and the efficiency is higher by adopting the air suction cooling mode;
(2) The ambient air flows enter from the side walls at two sides of the battery shell to radiate the battery pack, so that the radiation is more uniform;
(3) The negative pressure fan can play the role of cooling the battery pack while playing the role of dust collection.
