Description

A kind of heat management system and electric car of electric car
Technical field
The utility model relates to electric car constant temperature to protect system, the heat management system and electricity of especially a kind of electric car Electrical automobile.
Background technique
Due to the service life of battery and the limitation of course continuation mileage, electric vehicle is still within the starting stage at present.Exploitation one Kind is stable, length is continued a journey, the power battery of long-life, is always the target of each battery, automobile vendor's exploratory development;And it influences Electric car continuation of the journey, the mainly battery performance in service life, therefore on the one hand each battery manufacturer tries every possible means and expands battery capacity, open Send out new material;On the other hand start in terms of giving full play to battery performance two, battery is for performance by such environmental effects It is fairly obvious, especially under cryogenic battery performance decline it is fairly obvious;Although and can improve makes under the high temperature conditions With performance, but if being more than that certain temperature can then cause the dilatancy of battery and cause security risk.Therefore, at this stage Under the premise of the breakthrough of battery performance not substantially, it is in battery under optimum working temperature and gives full play to its effect and be Improve the key and effective measures of automobile power cell performance.Existing thermal management system of electric automobile radiator structure is complicated, and Each component heat dissipation interferes with each other, and radiating efficiency is low.
Summary of the invention
Technical problem to be solved in the utility model is, in view of the shortcomings of the prior art, providing a kind of heat of electric car Management system and electric car, each component, which independently radiates, not to be interfere with each other, and improves radiating efficiency.
A kind of in order to solve the above technical problems, the technical scheme adopted by the utility model is: heat management of electric car System, including battery;The battery is connect with the first water pump;First water pump and charging unit, electric machine controller, DC/DC Converter, battery heat exchanger, the second water pump, motor connection;Second water pump and charging unit, electric machine controller, DC/DC become Parallel operation, motor connection;The charging unit, electric machine controller, DC/DC converter are in parallel;The battery heat exchanger and air blower, Refrigerating evaporator, water heater, compressor, hydro-thermal PTC connection;The hydro-thermal PTC and the cell communication.
First water pump passes sequentially through the first triple valve, the first automatically controlled flow valve, the second triple valve and the charging and fills It sets, the connection of electric machine controller, DC/DC converter;The hydro-thermal PTC passes through third triple valve and the cell communication;Described One automatically controlled flow valve connects second water pump by the 4th triple valve;Second water pump connects the charging by four-way valve and fills It sets, electric machine controller, DC/DC converter.
The first radiator is installed on water route between first triple valve, third triple valve, further improves heat dissipation Effect.
The second radiator is installed on water route between 4th triple valve, the second water pump, further improves heat dissipation effect Fruit.
Second automatically controlled flow valve one end is connected to the water route between the battery, third triple valve, the other end and described the Water route connection between two water pumps, four-way valve.
First radiator is arranged in parallel with expansion valve.
Third radiator, the third radiator are provided on pipeline between the refrigerating evaporator and the compressor Side is provided with electric fan.Electric fan can give radiator heat-dissipation.
Correspondingly, the utility model additionally provides a kind of electric car, uses above-mentioned heat management system.
Compared with prior art, had the beneficial effect that possessed by the utility model the utility model by electric drive, DC-DC, fill The Components Parallel Connection arrangement of the needs such as electric installation heat dissipation, has the advantages of simple structure and easy realization, and each component, which independently radiates, not to be interfere with each other, heat dissipation It is more efficient.
Detailed description of the invention
Fig. 1 is the utility model embodiment structure principle chart.
Specific embodiment
As shown in Figure 1, water pump is to provide power to water-cooling system cooling water;Triple valve and four-way valve are to be divided into water route Three and four branches;Motor, electric machine controller, charging unit, DC-DC, battery are cooled components;Hydro-thermal PTC is (the winter use) of heated cooling fluid;Battery heat exchanger is radiate to battery (summer high temperature use), and air blower is blown to cockpit Wind;Refrigerating evaporator is summer to drive indoor air conditioner refrigerating component, and water heater is winter driving heating of house component;Electricity Controlling flow valve is to control water flow in pipeline with automatically controlled mode;Motor compressor is that refrigerant compression is used, and is air-conditioning part Part.Air blower, refrigerating evaporator, water heater are combined into HVAC(air handling system).
Summer battery is cooling:
By battery heat exchanger (chiller), adjustment flows into the temperature of the coolant liquid of battery pack (pack), and then adjusts electricity Pond packet temperature;
The cooling of three electric (charger and tri- attachment, motor driver, DC-DC accessories) controls coolant liquid by water circulating pump Flow velocity, to control the radiating efficiency of each electrical part.
The heating of winter battery:
Cooling water is heated by the waste heat and hydro-thermal PTC of motor cooling water automatically, battery pack is heated jointly, wherein water Hot PTC is connected near battery water inlet, and to reduce heat losses, effect is to carry out thermal compensation;Motor cooling water is main Heating temperature source.
The heating of winter driving room:
By the waste heat and water heater two parts of motor cooling water collectively as the heat source of heating, preferentially cooling water is selected to add Heat, when cooling water is not enough to supply the heat of heating, water heater work compensation heating.
