Description
Technical field: the present invention relates to a kind of forced air cooling flat three-phase linear asynchronous motor cooling system.
Technical background: the present flat three-phase linear asynchronous motor of towing vehicle in the world, because power of motor is big, caloric value height, linear electric motors are placed on the very crowded bottom of vehicle, motor volume is subjected to the restriction of environment for use, and ventilation cooling system becomes the key technology of linear electric motors.
Summary of the invention: the purpose of this invention is to provide a kind of compact conformation, occupy little space, air channel structure is reasonable, and wind flow is unobstructed, the forced air cooling flat three-phase linear asynchronous motor cooling system of good cooling results.The key technology of forced air cooling linear electric motors is the type of cooling and cooling structure.In order to achieve the above object, the technical solution used in the present invention is: a kind of forced air cooling flat three-phase linear asynchronous motor cooling system, iron core in the cooling system is by a plurality of domes, the punching of round bottom dovetail groove is overrided to form, there are clamping plate the iron core both sides, clamp with bolt, iron core vertically forms profile of tooth, the profile of tooth of iron core top is called fin, front end-plate is welded at the clamping plate two ends respectively, end plate, clamping plate top connects upper cover plate and forms a casing that passes in and out cold wind is plenum chamber, at least one typhoon machine is installed on plenum chamber top, blower fan is fixed on the upper cover plate, above fin, supercharging device is installed near in the plenum chamber at ventilating opening place, cold wind in the plenum chamber flows to the end air compartment through ventilating opening, and the upside of ventilating opening is installed convertor assembly in the air compartment of end, and convertor assembly is the bat shape, in the air compartment of end winding overhang is arranged, deep bead be installed in respectively the end air compartment the side and below.
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 system, form the capability of independent innovation.
Technique effect of the present invention:
1, cooling system 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.
