在空调器制冷运行时,压缩机1排出的高温高压制冷剂先进入冷凝器2,制冷剂经冷凝器2节流后,变成低温低压的制冷剂,低温低压的制冷剂沿着第一制冷剂管路91流入换热装置4,在流经换热装置4时与换热装置4内的冷却水发生热交换,对冷却水进行降温,被冷却的冷却水沿着冷却水管路流入水冷散热器110,冷却水在流经水冷散热器110时,使水冷散热器110附近的温度降低,从而降低电池5的温度,从水冷散热器110流出的冷却水沿着冷却水管路重新流入换热装置4,与流经换热装置4的制冷剂进行热交换,从而能够提高对电池5的降温效果。During the cooling operation of the air conditioner, the high-temperature and high-pressure refrigerant discharged from the compressor 1 first enters the condenser 2, and after being throttled by the condenser 2, the refrigerant becomes a low-temperature and low-pressure refrigerant. The agent pipeline 91 flows into the heat exchange device 4, and exchanges heat with the cooling water in the heat exchange device 4 when passing through the heat exchange device 4, and cools the cooling water, and the cooled cooling water flows into the water cooling and heat dissipation along the cooling water pipeline. When the cooling water flows through the water-cooling radiator 110, the temperature near the water-cooling radiator 110 is reduced, thereby reducing the temperature of the battery 5, and the cooling water flowing out of the water-cooling radiator 110 flows into the heat exchange device along the cooling water pipeline 4.

Heat exchange occurs, the temperature of the cooling water is raised, and the heated cooling water flows into the water-cooling radiator 110 along the cooling water pipeline. When the high-temperature cooling water flows through the water-cooling radiator 110, the temperature near the water-cooling radiator 110 increases, thereby The battery 5 is heated up, and the low-temperature cooling water flowing out from the water-cooled radiator 110 re-flows into the heat exchange device 4 along the cooling water pipeline, and exchanges heat with the refrigerant flowing through the heat exchange device 4, thereby improving the temperature rise of the battery 5 As an effect, in addition, it is possible to prevent the refrigerant from getting close to the battery 5, improving safety.

下面结合一个具体的实施例来详细地介绍本发明的技术方案。The technical solution of the present invention will be described in detail below in conjunction with a specific embodiment.
如图4所示,本发明的控制方法包括以下步骤:As shown in Figure 4, the control method of the present invention comprises the following steps:
S100:获取电池的温度。S100: Obtain the temperature of the battery.
示例性地,在车辆运行的过程中,可以通过设置在电池上的温度传感器来检测电池的温度,控制器获取到电池的温度之后,根据温度来选择性地打开第一电控阀并使空调器和水泵运行。其中,“根据温度,选择性地打开第一电控阀并使空调器和水泵运行”的步骤具体包括S210至S240。For example, during the running of the vehicle, the temperature sensor of the battery can be used to detect the temperature of the battery. After the controller obtains the temperature of the battery, it selectively opens the first electric control valve and activates the and the water pump are running. Wherein, the step of "selectively opening the first electric control valve and operating the air conditioner and the water pump according to the temperature" specifically includes S210 to S240.

After acquiring the temperature of the battery, the controller first compares the temperature of the battery with the first preset temperature to determine whether the temperature of the battery is higher than the first preset temperature.
如果判断结果为否,即电池的温度不大于第一预设温度,说明电池的温度不高,则接着执行步骤S220。If the determination result is no, that is, the temperature of the battery is not higher than the first preset temperature, it means that the temperature of the battery is not high, and then step S220 is executed.
反之,如果判断结果为是,即电池的温度大于第一预设温度,说明电池的温度过高,则接着执行步骤S230,即控制第一电控阀打开,并控制空调器以制冷模式运行,以便通过换热装置对冷却水进行降温,同时使水泵运行,以便通过水冷散热器来降低电池的温度。On the contrary, if the judgment result is yes, that is, the temperature of the battery is greater than the first preset temperature, indicating that the temperature of the battery is too high, then step S230 is performed, that is, controlling the opening of the first electric control valve and controlling the air conditioner to operate in cooling mode, In order to cool down the cooling water through the heat exchange device, and at the same time make the water pump run, so as to reduce the temperature of the battery through the water-cooled radiator.

The water heats up and at the same time runs the water pump to raise the temperature of the battery through the water-cooled radiator.
示例性地,第二预设温度设置为15度,当电池的温度小于15度时,说明电池的温度过低,需要对电池进行升温处理。Exemplarily, the second preset temperature is set to 15 degrees, and when the temperature of the battery is lower than 15 degrees, it means that the temperature of the battery is too low, and the battery needs to be heated up.

After the refrigerant is throttled from the condenser, it becomes a low-temperature and low-pressure gas-liquid two-phase state. When the refrigerant flowing out of the condenser flows through the heat exchange device, it is in contact with the cooling water flowing through the heat exchange device. Heat exchange reduces the temperature of the cooling water. The low-temperature cooling water flowing out of the heat exchange device flows into the water-cooled radiator along the cooling water pipeline, which reduces the temperature near the water-cooled radiator. The low-temperature air is blown to the battery, thereby cooling the battery more effectively.

When the refrigerant flows through the heat exchange device, it exchanges heat with the cooling water flowing through the heat exchange device to increase the temperature of the cooling water, and the high-temperature cooling water flowing out of the heat exchange device flows into the cooling water pipeline The water-cooled radiator increases the temperature near the water-cooled radiator.
