Description
Technical field
The present invention relates to electric automobile field, particularly to motor and the cooling system of driver of a kind of electric automobile.
Background technology
At present, the development of electric automobile obtains encouragement energetically and the promotion of national governments because of the concept of its environmental protection, in the power aspect of electric automobile core, motor and controller are the power resources of electric automobile, are also the two big parts that in drive system, caloric value is higher.Efficient and rational heat dissipation design, is to ensure that motor and the essential condition of driver reliability service.Traditional radiating mode mainly has natural air cooled, air blast cooling and three kinds of modes of Forced water cooling, air blast cooling is mainly used in low power product, to powerful product, Forced water cooling is current widely used radiating mode, but this radiating mode cost is the highest.
Summary of the invention
The deficiency existed for prior art, present invention is primarily targeted at motor and the cooling system of driver of the electric automobile providing a kind of low cost and good heat dissipation effect.
For achieving the above object, the technical scheme is that the motor of a kind of electric automobile and the cooling system of driver, the electric automobile driving apparatus constituted including motor and driver, also include automobile air conditioner compressor, described automobile air conditioner compressor connects the cooling line that can cool down electric automobile driving apparatus, the two ends of described cooling line connect with automobile air conditioner compressor respectively, being provided with coolant in described cooling line, described coolant is circulated by the drive of automobile air conditioner compressor in cooling line.
Preferably, described motor and the integrated setting of driver.
Preferably, described electric automobile driving apparatus is provided with temperature-detecting device.
Preferably, described automobile air conditioner compressor is respectively arranged with the first valve and the second valve with the junction of cooling line.
Preferably, described cooling line part in electric automobile driving apparatus is spiral setting.
Preferably, described first valve and the second valve are three-way valve.
The present invention has the advantage that relative to prior art, to have employed the electric automobile that automobile air conditioner compressor freezes, in coolant (coolant) blood circulation, by automobile air conditioner compressor being arranged extra bypass, motor and driver are used cold-producing medium cooling, and motor and driver share a cooling system.Compared to traditional water-cooling pattern, this type of cooling has only to a closed circuit, and design is simple, it is not necessary to highdensity cooling circulating water road is designed.Simultaneously as coolant heat exchange efficiency is significantly larger than the heat exchange efficiency cooling down water, so the operating temperature of motor and controller can be substantially reduced, extend the power range of motor and driver, the most beneficially reduction of product cost.
Accompanying drawing explanation
Fig. 1 is the structural representation sketch of the cooling system of the motor of a kind of electric automobile of the present invention and driver.
In figure: 1, motor；2, driver；3, automobile air conditioner compressor；4, cooling line；5, the first valve；6, the second valve；7, air-conditioning cooling recirculation system.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1, the motor 1 of a kind of electric automobile and the cooling system of driver 2, the electric automobile driving apparatus constituted including motor 1 and driver 2, also include automobile air conditioner compressor 3, described automobile air conditioner compressor 3 connects the cooling line 4 that can cool down electric automobile driving apparatus, the two ends of described cooling line 4 connect with automobile air conditioner compressor 3 respectively, being provided with coolant in described cooling line 4, described coolant is circulated by the drive of automobile air conditioner compressor 3 in cooling line 4.
The work process of the motor 1 of the electric automobile of the present invention and the cooling system of driver 2 is, to have employed the electric automobile that automobile air conditioner compressor 3 freezes, in coolant (coolant) blood circulation, by automobile air conditioner compressor 3 is arranged extra bypass, use cold-producing medium to cool down in motor 1 and driver 2, and motor 1 and driver 2 share a cooling system.Compared to traditional water-cooling pattern, this type of cooling has only to a closed circuit, and design is simple, it is not necessary to highdensity cooling circulating water road is designed.Simultaneously as coolant heat exchange efficiency is significantly larger than the heat exchange efficiency cooling down water, so the operating temperature of motor 1 and controller can be substantially reduced, extend the power range of motor 1 and driver 2, the most beneficially reduction of product cost.
In accompanying drawing, cooling line 4 uses dotted lines, air-conditioning cooling recirculation system 7 to use same compressor, so design to save production cost with the cooling system of the present invention, and refrigeration have also been obtained guarantee simultaneously.
Preferably, motor 1 and the integrated setting of driver 2.So the benefit of design is to can ensure that motor 1 and driver 2 can effectively share a cooling system, make motor 1 and driver 2 effectively to be cooled down simultaneously, integrated setting makes the design of cooling line 4 become simple, reduces technology difficulty and cost.
Further, driving means is provided with temperature-detecting device (this is known in the art general knowledge, is not drawn in accompanying drawing).Temperature-detecting device can detect motor 1 and the temperature of driver 2 in real time, thus can facilitate the signal that default cooling system opens and closes.The most not only can ensure that motor 1 and driver 2 when temperature is higher, coolant can enter in cooling line circulation circulation, and motor 1 and driver 2 can effectively be cooled down；Motor 1 and driver 2 cooling system when temperature is the highest can also be made to be closed, save the energy.
Wherein, automobile air conditioner compressor 3 is respectively arranged with the first valve 5 and the second valve 6 with the junction of cooling line 4.First valve 5 and the second valve 6 can determine aperture according to the numerical value that temperature-detecting device records, thus so that the amount of coolant in cooling line 4 can be supplemented according to the Temperature numerical detected, it is possible to ensure that what coolant and the energy was maximized is utilized.First valve 5 and the second valve 6 are three-way valve.
Improving, the cooling line 4 part in driving means is spiral setting.Screw type cooling line 4 can ensure that motor 1 can be cooled efficiently with driver 2.
The above is only the preferred embodiment of the present invention, and protection scope of the present invention is not limited merely to above-described embodiment, and all technical schemes belonged under thinking of the present invention belong to protection scope of the present invention.It should be pointed out that, for those skilled in the art, some improvements and modifications without departing from the principles of the present invention, these improvements and modifications also should be regarded as protection scope of the present invention.
