Cold wind is pressed into plenum chamber by blower fan, after in plenum chamber, passing through the supercharging device supercharging, be formed with the cold wind of pressure, cold wind flows to the end air compartment equably through fin, ventilating opening, convertor assembly changes the cold wind flow direction, make cold wind flow to winding overhang, deep bead changes direction once more with cold wind, makes distinguished and admirable end to winding overhang, flow out by exhausting window, reach cooling purpose.

The platypelloid type linear electric motors type of cooling of towing vehicle has two kinds, and a kind of is natural air cooled, and a kind of is forced air cooling.Forced air cooling electric efficiency height, volume be little, in light weight, occupied little space, reduced car body weight, increase the load-carrying ability of vehicle.In order to develop the linear electric motors track traffic technology of China, research and development belong to the core technology of China's independent intellectual property right, grasp forced air cooling flat three-phase linear asynchronous motor cooling device, form the capability of independent innovation.

Technique effect of the present utility model:

1, cooling device adopts four air channels, three Room to ventilate, and three Room comprise: a plenum chamber, two end air compartments; Four air channels: each air channel, plenum chamber both sides, each air channel of end air compartment, compact conformation occupies little space, and air channel structure is reasonable, and wind flow is unobstructed, good cooling results.

2, the cold wind in the plenum chamber is through even distribution whole box body after the supercharging, and the cold wind of discharge evenly enters the end air compartment through two passages.

3, there is the cold wind of pressure to change direction in the air compartment of end, winding overhang fully cooled off the back discharge by the air channel, both sides through twice.

4, fin is arranged at iron core top, increases area of dissipation, helps heat radiation, and good cooling results reduces electric machine temperature rise.
