Abstract
The utility model relates to a motor cooling unit of a mixed power electric vehicle, mainly including a fluid cooling motor 4, a motor radiator 1, a liquid pump 2, an electric fan 3, a temperature controlling unit 5 and a temperature sensing element 6. The fluid cooling motor 4, the liquid pump 2 are connected with the motor radiator 1 through the circulating liquid tube 9 respectively; the input end of the temperature control unit 5 is connected with the temperature-sensing element 6 located on the fluid-cooled motor and two output ends of the temperature control unit 5 are connected with the liquid pump 2 and electric fan 3 respectively; the motor radiator 1 and the engine radiator 7 are paralleled arranged on the upper course of cooling current; the electric fan 3 and the motor radiator 1 are parallel and arranged on the upper course of the cooling current. When the combination drive mode is working, the engine blower can be fully used in the heat dissipation and cooling of the motor radiator and the engine radiator simultaneously, thus achieves the aim of preserving energy and prolongs the electric fan's (which belongs to the motor radiator) service life.
Description
Technical field:
The utility model relates to a kind of hybrid-power electric vehicle motor cooling device.
Background technology:
Going from bad to worse of the growing tension of current global energy and environment driven the high speed development of new traffic tool-mixed power electric car.And motor is the critical piece of mixed power electric car, and motor can produce heat in the course of the work, and as not dispelling the heat, motor temperature will constantly rise, and reduces the useful life of motor, but burn-out motor when serious.That the mixed power electric car motor has is air-cooled, water-cooled, oil injection type etc.The motor with air cooling volume is big, Heavy Weight, radiating effect difference and the less mixed power electric car that is used for.And the cooling device of common water-cooled and oil injection type (below be referred to as liquid-cooled) motor is autonomous system, when cooling system is worked, start electric fan and water (oil) pump simultaneously, consumes more electric energy, and works long hours and can reduce the life-span of electric fan.
The utility model content:
The technical problems to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, and the cooling device that is used for the hybrid-power electric vehicle motor of a kind of efficient height, simple general-purpose, long service life is provided.
The utility model, comprise fluid-cooled electrical machine, motor radiating device, liquid pump, electric fan, temperature control unit and temperature-sensing element, fluid-cooled electrical machine, liquid pump and motor radiating device are connected by the circulation fluid pipe respectively, the input of temperature control unit is connected with temperature-sensing element on being arranged at fluid-cooled electrical machine, the output of temperature control unit is connected with electric fan with liquid pump, the parallel installation with engine radiator of motor radiating device and place the upstream of cooling blast.
The utility model because the parallel installation setting of motor radiating device with engine radiator, engine radiator supporting fan be located at the downstream of cooling blast, therefore, the motor radiating device supporting electric fan then be located at the upstream of cooling blast.
The utility model, described liquid pump are used to make cold liquid to circulate between fluid-cooled electrical machine and motor radiating device.Described temperature-sensing element is used for the temperature signal of fluid-cooled electrical machine is fed back to temperature control unit, and temperature control unit will be controlled the operation of liquid pump and electric fan, thereby the temperature of fluid-cooled electrical machine is controlled.
When mixed power electric car runs on combination drive pattern and fluid-cooled electrical machine temperature and is higher than the higher limit of setting, temperature control unit cuts off electric fan and the primer fluid pump operation automatically, when engine operation, make full use of engine blower, cooling motor radiator at first before cooling air enters engine radiator; When the fluid-cooled electrical machine temperature is lower than the lower limit of setting, automatic stop solution pump operation; In the pure motor driving pattern and when the fluid-cooled electrical machine temperature is higher than the higher limit of setting, electric vehicle engine is in closed condition, can't rely on engine blower to cool off again, temperature control unit starts electric fan and liquid pump operation automatically, the motor radiating device is dispelled the heat, reduce to the lower limit of setting when following when the fluid-cooled electrical machine temperature, temperature control unit stops liquid pump and electric fan operation automatically, still reaches the purpose of heat radiation.
The utility model owing to when the combination drive pattern, can make full use of engine blower and in to the engine radiator radiating and cooling motor radiating device be carried out radiating and cooling, reaches energy-conservation and prolongs the motor radiating device electric fan purpose in useful life.
