Bar circuit, i.e. cooling water second servo loop.
Electric automobile in use, vehicle outer side, car room, in battery case, the cooling water inlet of battery case and cold
But water out is respectively equipped with temperature sensor, the temperature for monitoring of environmental temperature, car room temperature and battery case.According to season
Section or the change of region, when environment temperature is more than more than 27 DEG C, part population can feel hotter, car room temperature and battery
The temperature of case is transmitted be subject to heat, and also more than more than 27 DEG C, the passenger in automobile needs air conditioner refrigerating, and the temperature of battery case
During more than more than 30 DEG C, then cooling and heat dissipation is needed to maintain appropriate operating temperature.At this time, the refrigerant air-conditioning system 1 in automobile
Refrigeration, the second valve port and the 3rd valve port of refrigerant triple valve 15 can open at the same time, and refrigerant is along the first circuit of refrigerant and refrigerant second
Circuit operates, wherein the openings of sizes of the second valve port and the 3rd valve port adjusts, so as to change the flow of the refrigerant in two circuits；
At the same time, the cooling water of battery water-cooling system 2 is along the first circuit cycle of cooling water, and cooling water passes through battery case A, by battery case
The heat of A take away and at water cooling heat exchanger 16 with refrigerant heat-shift.Air-cooled evaporation of the part refrigerant through refrigerant second servo loop
Device 18 freezes to car room, after the second expansion 17 valves atomization, absorbs in-car heat, returns compressor 11, another portion
Divide refrigerant then to exchange heat by water cooling heat exchanger 16 and cooling water, absorb the heat of cooling water, reduce the temperature of cooling water, return
Compressor 11.Since battery case A needs to cool down at this time, heater 22 is in holding state, and cooling water is without heating.
Under the collective effect of refrigerant air-conditioning system 1 and battery water-cooling system 2, car room greenhouse cooling to 22~27
DEG C, the temperature of battery case A is 20~30 DEG C, and at this temperature, the comfort level of passenger is optimal, and the operating temperature of battery is also for most
It is good.At this time, refrigerant air-conditioning system 1 can the intermittent energy for stopping refrigeration and work, saving battery case.Process of the automobile in traveling
In, battery last fever, therefore the cooling water of battery water-cooling system 2 continues to flow along the first circuit of cooling water, promotes dissipating for heat
Hair.After car room temperature rises, refrigerant air-conditioning system 1 continues to start.
And when season or region change, environment temperature is less than 20 DEG C, during even in less than 0 DEG C, the temperature of car room
Also change with environment, battery is in extremely low temperature, is not suitable for work.Automobile such as needs to start at this time, and car room need not be made
Cold, refrigerant air-conditioning system 1 shuts down, and the heater 22 of battery water-cooling system 2 starts, and heater 22 heats cooling water and rises
Temperature, cooling water are circulated through cooling water second servo loop, improve the temperature of battery case A, and cooling water absorbs the heat change of battery case A at this time
For hot water.At the same time, air blower 19 starts air blast, and heat when hot water to be flowed through to heater tank 25 is blown in air, so that
Improve the temperature of car room.After battery case A temperature is higher than 5 DEG C, you can start running.During traveling, battery case A is held
Temperature of continuing rising, after its temperature is higher than 30 DEG C, then needs to cool down battery, avoids it more than 40 DEG C.Stop adding for heater A at this time
Heat, cooling water is circulated through cooling water second servo loop, by condensation water tank 24 to cooling water temperature, so as to cool down to battery case A, together
When cooling water is absorbed to the heat of battery case A car room is blown to by air blower 19, car room is kept warm, fully profit
Use resource.
By monitoring of environmental temperature, car room temperature and battery temperature, reasonable adjustment cooling water and refrigerant are recycled back to
Road, cools down or heats up to car room and battery case in due course, car room temperature and battery temperature is maintained rational temperature, multiplies
Extend the service life of battery while objective comfortable.
In conclusion the battery of the air-conditioning battery heat-exchange system of the electric automobile of the application is cooled down using water-cooling pattern, it is cold
Matchmaker's air-conditioning system then includes air-cooled and two kinds of types of cooling of water cooling, according to environment temperature, car room temperature and battery temperature tune
It is whole, battery water-cooling system and refrigerant air-conditioning system are combined into heat exchange, the type of cooling and circulation loop is adjusted in due course, makes car room
Temperature and the operating temperature of battery are in appropriate temperature, save energy.
The upper only embodiments of the present invention, are not intended to limit the invention.For those skilled in the art
For, the invention may be variously modified and varied.All any modifications made in spirit and principles of the present invention, be equal
Replace, improve etc., it should all be included within scope of the presently claimed invention.
