Therefore provide a kind of rational in infrastructure, can ensure that the temperature of all batteries in power brick is all effectively controlled, the power brick heat management device that at utmost can reduce again power consumption becomes problem demanding prompt solution in prior art.
Utility model content
The purpose of this utility model is to overcome and uses electric heating to consume energy large technical deficiency when carrying out heat management to power brick, and provide a kind of rational in infrastructure, the one less again that consume energy is for electromobile air-cooled power brick heat management device.
The utility model provides a kind of air-cooled power brick heat management device for electric automobile, it is characterized in that described heat management device comprises blower fan, heat pump air conditioner, wind inlet channel, exhaust air flue, direct-connected air channel and air-cooled power brick, wherein heat pump air conditioner comprises condensation/vaporization device, compressor and evaporator/condensers, described blower fan is connected with the condensation/vaporization device in heat pump air conditioner by wind inlet channel, the air inlet of air-cooled power brick is connected with condensation/vaporization device by exhaust air flue, compressor is connected with evaporator/condensers with condensation/vaporization device respectively by refrigerant tubing, and condensation/vaporization device is also connected by refrigerant tubing with evaporator/condensers, the direct-connected air channel without heat pump air conditioner is separately had between the return air inlet of described blower fan and the return air inlet of air-cooled power brick, described air-cooled power brick also has the exhaust outlet directly leading to air, blower fan, wind inlet channel, condensation/vaporization device, exhaust air flue, air-cooled power brick, the circulation of enclosed wind can be formed between direct-connected air channel, heat pump air conditioner only cools air-cooled power brick or heats.
The heat management device that the utility model provides, when not starting heat pump air conditioner, closed by the return air inlet of air-cooled power brick, exhaust outlet is opened, by the air-flow through air-cooled power brick discharged to air.
When heat pump air conditioner works in cooling mode, condensation/vaporization device plays the effect of evaporator, and evaporator/condensers plays condenser effect;
When heat pump air conditioner work works in a heating mode, condensation/vaporization device plays the effect of condenser, and evaporator/condensers plays evaporator effect.
Compared with prior art, the beneficial effects of the utility model are:
The air-cooled power brick heat management device for electric automobile that the utility model provides, have employed the heat pump air conditioner being exclusively used in power brick temperature adjustment and heating and cooling are carried out to air-cooled power brick, and between blower fan and air-cooled power brick, be also provided with direct-connected air channel, the mode of closed cycle can be adopted to cool air-cooled power brick faster, outside air wind-cooling heat dissipating can be directly utilized again when battery-heating amount is little or outside air temperature is lower, adopt the heat management device of this structure, the heat pump air conditioner of appropriate size can be selected, thus can be under optimum operation load after heat pump air conditioner is started shooting as far as possible, can effectively put forward high-octane utilization ratio.Both decreased the electric energy needed for heating of battery, and obviously can increase the continual mileage of vehicle.When can avoid again adopting the main air-conditioning of vehicle cool power brick or heat in prior art simultaneously, owing to needing to carry out wind-guiding and the too low energy loss that causes of main air conditioner load and main air-conditioning life loss through complicated pipeline, the life-cycle use cost of electric automobile can be reduced.
Accompanying drawing explanation
The structural representation of a kind of air-cooled power brick heat management device for electric automobile that Fig. 1 provides for embodiment.
Embodiment
Below in conjunction with specific embodiment, and with reference to accompanying drawing, the utility model is described further:
As shown in Figure 1, the air-cooled power brick heat management device for electric automobile that the utility model provides comprises blower fan 1, heat pump air conditioner 2, wind inlet channel 4, exhaust air flue 6, direct-connected air channel 9 and air-cooled power brick 3, wherein heat pump air conditioner 2 comprises condensation/vaporization device 5, compressor 7 and evaporator/condensers 8, described blower fan is connected with the condensation/vaporization device in heat pump air conditioner by wind inlet channel, the air inlet of air-cooled power brick is connected with condensation/vaporization device by exhaust air flue, compressor is connected with evaporator/condensers with condensation/vaporization device respectively by refrigerant tubing, and condensation/vaporization device is also connected by refrigerant tubing with evaporator/condensers, the direct-connected air channel without heat pump air conditioner is separately had between the return air inlet of described blower fan and air-cooled power brick return air inlet, described air-cooled power brick also has the exhaust outlet directly leading to air, blower fan, wind inlet channel, condensation/vaporization device, exhaust air flue, can form between air-cooled power brick and direct-connected air channel enclosed wind circulation, heat pump air conditioner only cools air-cooled power brick or heats.
