The purpose of the utility model is to provide a kind of both effectively lowered the temperature to battery, guaranteed battery operated performance, can battery be produced waste gas again and discharge outside the car, guaranteed the electric automobile power battery cooling system of air cleaner in the car.
To achieve these goals, the technical scheme of the utility model employing is:
Said electric automobile power battery cooling system is made up of the exhausting assembly that is connected with the electrokinetic cell air outlet; Said exhausting assembly; Comprise the air draught type centrifugal blower and suck the air channel; The air inlet in said suction air channel is connected with said electrokinetic cell air outlet; The air outlet in said suction air channel is connected with said air draught type centrifugal blower inlet scoop, and said air draught type centrifugal blower air outlet is connected with discharge pipe, and said discharge pipe is connected with the car load exhaust outlet.
On the air outlet of the left and right sides of said electrokinetic cell, all be connected with the exhausting assembly.
Said exhausting assembly is symmetrically distributed in the both sides of spare tire in the boot.
Said air draught type centrifugal blower comprises that air blast reaches and the brushless electric machine that power is provided for air blast, is provided with the spiral case assembly in the air blast outside; The air blast of said air draught type centrifugal blower is all vertically placed, and is arranged at the position near boot carpet plate muscle two ends.
Said suction air channel is the two-part structure, sucks the two ends, air channel and passes carpet plate muscle, sucks two sections both sides that are symmetrically distributed in carpet plate muscle in air channel.
The technical scheme that said electric automobile power battery cooling system adopts has the following advantages:
At first; Said cooling system; The air draught type centrifugal blower of exhausting assembly is constantly extracted the hot-air in the electrokinetic cell out through sucking the air channel, after the Hot air quilt in the battery module is taken away, forms negative pressure in the battery module; The indoor normal temperature air of automobile is inhaled in the battery module, and battery pack is played cooling effect;
Secondly; Said cooling system; When the air draught type centrifugal blower is drawn the inside battery hot-air; The waste gas that inside battery produces is discharged to the car load air outlet through the discharge pipe that is connected with air draught type centrifugal blower air outlet, and it is outdoor to be discharged to automobile from the car load air outlet, can guarantee the vehicle air cleaning like this;
Again secondly, two exhausting assembly parallel waies about employing when increasing throughput, guarantee the inner cooling of battery module evenly fully, have increased cooling effect;
At last, whole cooling system all is arranged in the automobile trunk bottom space, saves the space; After the inner formation of the electrokinetic cell negative pressure, what get into electrokinetic cell is normal temperature air in the car, saves resource.
