The battery pack case at least two opposites are equipped with the ventilation opening that connection forms heat dissipation wind channel；
The hollow out battery bracket agrees with the shape of each battery core and is set as comprehensive hollow out；
The pcb board is parallel with two opposite of the battery pack case, and is equipped with multiple apertures.
Preferably, the battery pack case includes the upper cover and lower cover for being mutually two opposite, and the upper cover is equipped with more
A shutter shape ventilation opening；Multiple rectangular vents are covered under described.
Preferably, the hollow out battery bracket includes the upper hollow out battery bracket and lower hollow out battery bracket mutually fastened,
The multiple hollow out battery core brackets for agreeing with battery core shape are formed after fastening, a hollow out battery core bracket accommodates a battery core.
Preferably, the hollow out battery bracket is parallel with the pcb board.
The battery core and the pcb board are electrically connected.
A kind of battery pack radiator provided by the utility model, is placed in the motor air outlet of product, by battery
Ventilation opening is set in incrustation at least two opposites and forms the heat dissipation wind channel for flowing through battery core, and sets the bracket of fixed battery core to
Comprehensive engraved structure, multiple apertures are arranged in the place for not influencing circuit also on pcb board, so that motor air outlet is blown out
Wind can be come into full contact with battery core so that heat dissipation area is maximum, radiating rate is fast.The utility model can not increase heat dissipation
Device under the premise of not increasing material cost, using the wind-force of hand-held cleaners own motor, low cost and effectively improves electricity
The rate of heat dispation of Chi Bao.
