Abstract
The utility model discloses a cooling device for a motor-driven bus battery pack. The cooling device comprises a motor-driven compressor, a condenser, a condensation fan, a dry liquid storage device, an expansion valve, an evaporimeter and a motor-driven water pump, wherein the condensation fan is positioned above the condenser; the liquid storage device is connected with an outlet of the condenser; the motor-driven compressor is connected with an inlet of the condenser; the other ends of the liquid storage device and the motor-driven compressor are respectively connected with the expansion valve; and the other end of the expansion valve is connected with the evaporimeter and the motor-driven water pump in sequence. The device is an independent temperature control device, only used for controlling the temperature of the battery pack, so an air conditioner in a bus does not need to be started. The device is simple in structure and saves energy.
Description
Technical field
The utility model belongs to battery of electric vehicle group cooling device, specially refers to electronic big bus car battery pack cooling device.
Background technology
Power brick is the critical component of electric automobile as the main energy-storage travelling wave tube that loads on the electric automobile, directly has influence on the performance of electric automobile.But the performance in high-power drive pond is responsive to variations in temperature, when vehicle moves under the different travel conditions of checkers such as high speed, low speed, acceleration, deceleration, battery can discharge with different multiplying, give birth to hot speed with difference and produce a large amount of heats, if the batteries of electric automobile group at high temperature can not get timely heat radiation, will cause the too high or temperature distributing disproportionation of battery pack system temperature even, reduce the battery charging and discharging cycle efficieny the most at last, influence power and the energy performance of battery, also will cause thermal runaway when serious, influence fail safe and the reliability of battery; Moreover at low temperatures, the electrochemical reaction of inside battery need preheat power brick in advance because temperature influence can not normally move.Therefore in order to make power brick performance optimum performance and life-span, therefore must carry out effective heat management to power brick.
Traditional electronic big bus car or with electronic hybrid power big bus car, usually its battery pack does not arrange independent cooling device, mainly be to rely on the air-conditioning in the car body that the temperature of battery pack is controlled, inaccuracy so not only, and the unlatching of the air-conditioning in the big bus car mainly is according to deciding in season and weather, iff being the air-conditioning of opening whole compartment for the temperature of battery pack is controlled, the wasting of resources is very big, and has influenced the global comfort in the compartment.
Summary of the invention
The purpose of this utility model is to provide a kind of cooling device for electronic big bus car battery pack, and this device is an independently temperature control equipment, only controls at battery pack, need not to open the air-conditioning in the compartment, and this apparatus structure is simple, the saving energy.
For achieving the above object, the technical solution of the utility model is:
A kind of electronic big bus car battery pack cooling device, comprise motor compressor, condenser, condenser fan, dry reservoir, expansion valve, evaporator, electric water pump, it is characterized in that: condenser fan is positioned at the condenser top, reservoir is connected with condensator outlet, motor compressor is connected with condenser inlet, the other end of reservoir and motor compressor is connected with expansion valve simultaneously, and the expansion valve other end links to each other with evaporator, electric water pump successively.
Good effect of the present utility model is: the utility model by one independently Small Refrigerating Equipment be electronic or hybrid power big bus on-vehicle battery group cools, overcome the big bus car and need open whole compartment air-conditioning and come the drawback of lowering the temperature for battery pack, saved resource greatly.This cooling device is the design of modular small simultaneously, only need provide DC power supply, just can be according to the temperature treatment needs of battery pack, and the cooling water that different temperatures and different flow be provided is to the cooling of lowering the temperature of on-vehicle battery bag, and is simple in structure.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Be described further below in conjunction with 1 pair of embodiment of the present utility model of accompanying drawing.
Referring to Fig. 1, motor compressor 4 is directly driven by high-voltage DC power supply, compressed refrigerant, high temperature and high pressure gaseous refrigerant is entered in the condenser 1 by the pipeline that links to each other with condenser 1 import, condenser fan 2 places the top of condenser 1, condenser fan 2 is passed the fin of condenser 1 outside from condenser 1 below suction outside air, and condenser 1 internal refrigeration storage agent liberated heat is discharged into the external environment from the top; Condenser 1 internal refrigeration storage agent so the back liquefy cold-producing medium that obtains cooling flow into dehumidifying and buffering the dry reservoir 3 from its lower end outlet, after flowing into expansion valve 5 throttlings and step-down, pipeline flows to the heat of evaporation absorption cooling water in the evaporator 6 then, flow back to expansion valve 5 by pipeline after becoming the cold-producing medium of gaseous state, sucked compression again by motor compressor 4, begin new circulation.Take out next high-temperature cooling water inflow evaporator 6 by the electric water pump 7 that pipeline is connected from battery pack with evaporator 6 opposite sides, in evaporator 6 between cold-producing medium and the cooling water heat exchange takes place, cold-producing medium heat absorption in the evaporator 6 heats up, the cooling and cooling water is cooled, cooling water is sent to the coldplate cool batteries of battery pack then.The temperature of battery pack can directly accurately realize by the rotating speed of regulating motor compressor 4 and electric water pump 7.
