After adopting such scheme; because the present invention has increased a kind of heat management structure; this structure can solve car heating of house and defrosting (or demist) problem of preceding windscreen in winter; pass through the motor controller controls first radiator work in the time of in the winter time; second radiator is not worked; windscreen defrosted and the car heating of house before first radiator can be automobile; prolonged for second radiator fan motor useful life simultaneously; first radiator can work on when summer second, the radiator fan motor broke down especially, effectively protects motor and controller thereby the parallel way that is adopted has improved the reliability of pure electric automobile heat management.
The present invention is described in more detail below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1, the present invention is a kind of heat management device of electric car, and it comprises motor with watter cooling 1, electric machine controller 2, water pump 3, normally open solenoid valve 4, flow control valve 5, first radiator 6, second radiator 7 and expansion tank 8.
The heat radiating water jacket of described motor with watter cooling 1 is connected with water pump 3 with normally open solenoid valve 4, first radiator 6 by one road pipeline.Electric machine controller 2 is connected with normally open solenoid valve 4 by electric wire, closes normally open solenoid valve 4 when electric machine controller 2 has output, opens normally open solenoid valve 4 during no-output.When first radiator, 6 control switch (not shown)s were opened, the 6 electric fan work of first radiator were also given electric machine controller 2 by electric wire with signal.
The heat radiating water jacket of described motor with watter cooling 1 is connected with water pump 3 with flow control valve 5, second radiator 7 by another road pipeline.Electric machine controller 2 is connected with flow control valve 5 by electric wire, and the aperture of controllable flow adjustable valve 5, flow control valve 5 aperture scopes are from 0%～100%, electric machine controller logical 2 is crossed electric wire and is connected with the fan electromotor of second radiator 7 also and can controls rotation speed of the fan, electric machine controller 2 also is connected with water pump 3 by electric wire, after pure electric automobile starts, electric machine controller 2 output signal water supply pumps 3, water pump 3 entrys into service.
On water pump 3 inlet pipelines, also be connected with expansion tank 8, add water by expansion tank 8 to heat management structure, expansion tank 8 also removes gas port by the degasification pipeline with the delivery port place of the heat radiating water jacket of motor with watter cooling 1 and is connected, and is used to remove the water vapour of this structure generation in service.
The course of work of the present invention is as follows:
After pure electric automobile starts, electric machine controller 2 is exported to water pump 3, water pump 3 running drive water (or anti-icing fluid) flow through successively electric machine controller 2 and motor with watter cooling 1 heat radiating water jacket and take away electric machine controller 2 and heat that 1 work of water-cooled drive motors produces.
