Description of the drawings
Fig. 1 is the schematic diagram of present system.
Specific implementation mode
Invention is described in detail with reference to the accompanying drawings and examples.
As shown in Figure 1, car air-conditioner battery cooling system proposed by the present invention includes：Compressor 1, condenser 2, first steam
Send out device 3, the second evaporator 4 and a heat exchanger 5.The refrigerant of condenser discharge is divided into two-way, and the first via is through first throttling device 6
With the first evaporator 3, cool down for battery, the second tunnel cools down through second throttling device 7 and the second evaporator 4 for passenger, system
Cryogen continues to exchange heat after the first and second evaporator heat exchanges in heat exchanger 5, and at heat exchanger exit mix, after through pipe
Road returns to compressor 1.
It is equipped with gas-liquid separator 8 in suction side, oil eliminator 9 is equipped in compressor air-discharging side, is detached in exhaust
The oil gone out returns to compressor lubrication system through filter 10, oil return capillary 11.
In Fig. 1 the embodiment described, the first and second throttling sets use electric expansion valve.Second evaporator outlet pipeline
In be equipped with check valve 13.Compressor, gas-liquid separator and condenser are as a unit, the first and second throttling sets, first
With the second evaporator and heat exchanger as second unit, it is connected to by shut-off valve 12 between first unit and second unit.
When work, the gaseous coolant of low-temp low-pressure compresses the gas for becoming high temperature and pressure by compressor 1, passes through pipeline stream
Condensed device 2 carries out the liquid that forced-convection heat transfer becomes high temperature and pressure with environment under the action of outer wind turbine 21, is then divided into
Two-way, the first via pass through first throttling device 6（Electric expansion valve）Cool down to the first evaporator 3 to battery case.Second tunnel is passed through
Second throttling device 7（Electric expansion valve）To the second evaporator 4 to people's cooling by bus.It is cold after the first via and the evaporation of the second tunnel
Matchmaker continues to exchange heat in heat exchanger 5, is then mixed at heat exchanger exit, compression 1 is returned to after gas-liquid separator 8.
Since evaporator cannot have condensation problem, institute to the environment temperature in battery case to be ensured simultaneously between 35-45 DEG C
It to be controlled between 20-30 DEG C with leaving air temp of the wind after the first evaporator 3.This system is by controlling first throttling device
The rotating speed of 6 throttlings and the first inner blower 31 makes the evaporating temperature of the first evaporator 3 at 7-12 DEG C, while refrigerant is being passed through
It is overheated after first evaporator, the degree of superheat controls between 10-15 DEG C.Under normal circumstances, if only the first evaporator and maintained
So high evaporating temperature may result in that suction pressure of compressor is excessively high to cause the pressure at expulsion of compressor excessively high indirectly.
In order to solve the problems, such as that compressor pressure is excessively high, the present invention devises second throttling device 7 and second in systems
Evaporator 4.Second evaporator 4 is used for riding space, cools down to driver or passenger.Made by adjusting second throttling device 7
The evaporating temperature of second evaporator is at 6-8 DEG C, preferably 7 DEG C, while reducing the wind speed of the second inner blower 41 so that the second evaporation
Refrigerant evaporation in device 4 is incomplete, i.e. gas-liquid two-phase state.
The refrigerant overheated in first evaporator 3（Since the temperature of refrigerant evaporator outlet in an overheated state is higher than first
The evaporating temperature of evaporator, about at 15 DEG C or so）Incomplete refrigerant is evaporated in the second evaporator 4（Evaporation is incomplete, cold
Matchmaker evaporator outlet temperature also in the state of gas-liquid two-phase, while evaporator pipeline is steamed there are certain pressure loss
The temperature of device outlet is sent out about at 5 DEG C or so）Forced-convection heat transfer under the action of heat exchanger 5 and wind turbine 51, and in heat exchanger
Exit mixes.Since the refrigerant that the second evaporator 4 comes out is gas-liquid two-phase, and the refrigerant that the first evaporator 3 comes out only has gas
State, the refrigerant on the second tunnel continues to have occurred phase transformation when heat exchanger 5 exchanges heat, therefore mixed temperature is closer to heat exchange
The outlet pipe temperature of device 5, about 6 DEG C（Refrigerant, which is undergone phase transition, has gasification latent heat, not increased in temperature, can absorb big
The heat of amount）.Mixed refrigerant returns to compressor 1 by gas-liquid separator 8, refrigerant state at this time（Temperature and pressure）
Compressor Discharge Pressure will not be caused excessively high through being in rational state.Refrigeration system another week in a period in this case
The stable operation of phase.
Car air-conditioner battery cooling system proposed by the present invention is combined with air conditioning system for vehicle, while to Vehicular battery and being multiplied
Vehicle personnel are freezed, and not only so that Vehicular battery works between 35 to 45 DEG C, while control evaporator leaving air temp exists well
The problem of zone of reasonableness, there is no condensations.In addition, refrigerant after being evaporated with car air-conditioner and the refrigerant after exchanging heat with battery are mixed
It closes, reduces low pressure, effectively prevent the excessively high problem of compressor high pressure.
Above-described embodiment is merely to illustrate the specific implementation mode of the present invention.It should be pointed out that for the general of this field
For logical technical staff, without departing from the inventive concept of the premise, several deformations and variation can also be made, these deformations and
Variation should all belong to the scope of protection of the present invention.
