Description
Technical field
The utility model relates to the electronlmobil field, specially refers to the electric automobile whole cooling system.
Background technology
Automobile industry is the key pillars of the national economy industries, is playing the part of important role in national economy and social development.Along with becoming increasingly conspicuous of energy problem and problem of environmental pollution, electronlmobil has been subject to government and automobile vendor more and more payes attention to.The parts such as battery for electric automobile group, electric machine controller, drive motor have replaced traditional combustion engine, and these parts have certain requirement to the scope of operating temperature, so the cooling system of electric automobile whole has been compared very big-difference with traditional diesel locomotive.
Heat dissipation design for certain parts of electronlmobil is arranged at present, for example the Chinese patent literature publication number is CN202094250U, open day is the utility model patent of 2011.11.28, battery radiating device of electromobile is disclosed, system comprises a housing and a radiating module, and this housing has an accommodation space, and this radiating module has at least one cooling chip and at least one radiating fin, this at least one cooling chip binds should housing, and this at least one radiating fin binds should at least one cooling chip.This technical scheme can reduce the heat that battery of electric vehicle produces, and makes battery of electric vehicle be maintained at better operating temperature, but just dispels the heat for battery specially.If as this each parts is done respectively an independently heat dissipation design, because the heat generating components of electronlmobil is more, that will cause the cooling system structure of car load complicated, and cost is expensive, and can not take into account influencing each other of all parts heat radiation, so the radiating efficiency of car load is lower.
The utility model content
The utility model is for solving the problems of the technologies described above, provide a cover complete, economic electric automobile whole cooling system, this system not only can carry out to battery pack, electric machine controller and the drive motor of electronlmobil the actv. heat radiation, guarantee that battery pack, electric machine controller and drive motor are operated in the rational range of temperatures, can also utilize the waste heat of refrigerant fluid to solve heating and the defrosting problem of electronlmobil.

Interchange of heat of the present utility model water route is designed to parallel-connection structure, be because the electric machine controller cal val is larger, and battery pack is stricter to temperature requirement, therefore selects battery pack cooling in parallel with electric machine controller.Avoided the heat radiation of electric machine controller on the impact of battery pack on the one hand, on the other hand, the loss of pressure in interchange of heat water route in parallel is less.The leaving water temperature setting of electric machine controller is lower than 45 ℃, satisfies the cooling requirement of drive motor, therefore utilizes the refrigerant fluid that flows through electric machine controller drive motor to be cooled off again.
The cooling-liquid temperature that flows through thermal component can raise, because the heat dissipation capacity of electronlmobil is different under each operating mode, so the temperature rise of refrigerant fluid also is not quite similar.If the temperature rise of refrigerant fluid is less, then need not pass through radiator, this moment, refrigerant fluid directly flowed back to water pump, the next circulation of beginning after the water pump pressurization.If the temperature rise of refrigerant fluid is larger, then refrigerant fluid needs partly or entirely through the radiator cooling, flows back to water pump after the cooling to begin next circulation again.The radiator control cock can open or close the passage that refrigerant fluid flows to radiator according to temperature signal, and the amplitude that can regulate the valves and open according to temperature signal, and then regulates the flow of refrigerant fluid inflow radiator.
When the refrigerant fluid temperature rise is larger, the range of temperatures that only relies on free convection to be difficult to refrigerant fluid is reduced to requirement, need cooling fan to come forced convection this moment.The rotating speed of cooling fan is controlled by the temperature control thermistor switch, and according to the height of radiator outlet cooling-liquid temperature, the rotating speed of cooling fan can be regulated automatically.
When outside air temperature was low, windshield may frosting, and this will have a strong impact on the sight line of navigating mate.The heating demand is arranged in the automobile bodies in winter in addition.The cooling-liquid temperature that flows through heat generating components is higher, can utilize this moment refrigerant fluid and the cold air that flows through the heater unit heat exchanger to carry out heat exchange, and a heated air part is delivered to wind screen defrosting, and a part is sent into heating in the compartment.
Coolant recovery tank is communicated with outgate on the radiator by flexible pipe.After cooling-liquid temperature raise, volume can expand, and in order to prevent the hypertonia in the whole cooling system, refrigerant fluid is entered in the coolant recovery tank by the radiator outgate when pressure surpasses predetermined value.When cooling-liquid temperature reduced, the pressure in the whole cooling system reduced thereupon, and refrigerant fluid is got back to again radiator by coolant recovery tank when pressure is lower than predetermined value.Coolant recovery tank can also be eliminated the bubble in the cooling-liquid cycle loop.
The beneficial effects of the utility model are:
The utility model can carry out system, effectively heat radiation to the electric automobile whole heat generating components, can make battery pack, electric machine controller and drive motor be in rational range of temperatures, and the waste heat that can utilize refrigerant fluid has solved heating electric vehicles and defrosting problem, has improved the energy utilization efficiency of Full Vehicle System.
