[0045] An embodiment of the present utility model provides an automobile, including a power battery 9 and an air-conditioning cooling system; the power battery 9 is a component to be cooled.

[0046] As an example, the vehicle includes a power battery 9 and a cooling system; the power battery 9 is a component to be cooled and serves as the energy source of the new energy vehicle, mainly composed of battery cells or battery modules, circuits, an electronic control unit, etc. The air-conditioning cooling system includes a condenser 1, an air-conditioning box 2, and a cooler 3. The condenser 1 is used to dissipate heat from and cool down the high-temperature and high-pressure gaseous refrigerant, condensing it into a medium-temperature and high-pressure liquid refrigerant; the air-conditioning box 2 is used to generate condensed water when the air conditioner uses the liquid refrigerant for refrigeration; the cooler 3 is integrated into the air-conditioning circuit to enable heat exchange between the refrigerant and the high-temperature coolant, with the refrigerant cooling down the coolant to provide low-temperature coolant. During installation, the first end of the condenser 1 is connected to the liquid inlet of the air-conditioning box 2, and the liquid outlet of the air-conditioning box 2 is connected to the liquid inlet of the power battery 9 for transmitting condensed water, achieving cooling and heat dissipation of the power battery 9 through the condensed water of the air-conditioning box 2; the second end of the condenser 1 is connected to the liquid inlet of the cooler 3, and the liquid outlet of the cooler 3 is connected to the liquid inlet of the power battery 9 for transmitting coolant, achieving cooling and heat dissipation of the power battery 9 through the coolant in the cooler 3. With this arrangement, compared with only using the coolant in the cooler 3 to cool and heat dissipate the power battery 9 in the prior art, cooling and heat dissipation of the power battery 9 using the condensed water of the air-conditioning box 2 is added, which not only ensures the refrigeration effect of the air conditioner but also makes full use of the waste energy of the condensed water, achieving the effect of energy conservation and consumption reduction.

[0047] In this embodiment, the cooling of the power battery 9 consists of a refrigerant cycle and a water cooling cycle: The refrigerant cycle is composed of a compressor 7, a condenser 1, an electronic expansion valve, an air-conditioning box 2, a cooler 3, a gas-liquid separator, etc. The refrigerant flows through these components in sequence to form a refrigerant cycle; the water circuit cycle is composed of a cooler 3, a proportional three-way valve 5, a water pump 6, a power battery 9, a water kettle 4, etc. The coolant and condensate mixture flows through these components to form a water circuit cycle. When in use, the driver or passenger turns on the air conditioner through the air-conditioning panel, the host interface, voice, etc. The air-conditioning system starts to cool. After the refrigerant is compressed by the compressor 7 and condensed by the condenser 1, a part of it flows into the air-conditioning box 2, and the other part flows into the cooler 3. The refrigerant evaporates in the evaporator core of the air-conditioning box 2, and condensate is formed on the surface of the evaporator core, with a temperature of about 10°C to 20°C. The refrigerant evaporates and absorbs heat in the cooler 3, exchanges heat with the coolant, the temperature of the coolant decreases, and the temperature is about 20°C, then the water pump 6 is turned on; the condensate flows into the proportional three-way valve 5, and the flow rate is controlled by the proportional three-way valve 5. At the same time, the coolant flows into the proportional three-way valve 5, and the flow rate is controlled by the proportional three-way valve 5. On the one hand, the refrigerant evaporates and absorbs heat in the cooler 3, and the refrigerant exchanges heat with the coolant, that is, the refrigerant cools down the coolant. The low-temperature coolant flows out of the cooler 3 and then mixes with the condensate; on the other hand, after the air conditioner cools down, condensate is formed on the surface of the evaporator core of the air-conditioning box 2. The condensate flows through the condensate pipe to the proportional three-way valve 5 and then converges with the coolant. In this example, the air-conditioning condensate is used to cool down and dissipate heat from the power battery 9. Since there is less condensate when the air conditioner starts to cool, when the condensate flow rate is less than 10 L / min (this flow rate value is determined according to the size of the power battery 9), the coolant and condensate mixture flows into the power battery 9 to cool down and dissipate heat from the power battery 9, then flows out of the power battery 9 to the water kettle 4, and then flows into the cooler 3 to form a new cycle. When the condensate flow rate is not less than 10 L / min, the heat exchange between the coolant and the refrigerant in the cooler 3 is stopped, and the condensate directly flows into the power battery 9 to cool down and dissipate heat from the power battery 9. Then the condensate flows out of the power battery 9 and then to the water kettle 4. When the condensate volume exceeds the storage capacity of the water kettle 4, the condensate is directly discharged outside the vehicle. When the temperature inside the power battery 9 is controlled below 35°C, the relevant work is stopped. Such a setting ensures that the refrigerant used for cooling the power battery 9 is completely used for vehicle interior cooling, which not only guarantees the refrigeration effect of the air conditioner but also makes full use of the waste energy of the condensate, achieving the effect of energy conservation and consumption reduction for the whole vehicle.
