When the temperature in the cabinet 1 is high in summer, the air conditioner main unit 3 is started, and the refrigerant in the refrigerant container is compressed into a high-temperature and high-pressure gas in the compressor, and then sent to the condenser. The refrigerant releases heat and condenses into a liquid. The liquid refrigerant passes through a drying filter to remove impurities, and then is decompressed by an expansion valve to become a low-temperature and low-pressure gas-liquid mixture. After that, the low-temperature and low-pressure refrigerant absorbs heat in the evaporator, thereby lowering the indoor temperature, and becomes a gas again and is sent to the refrigerant container, and then is sucked back by the compressor to start a new cycle. In the above process, the fan in the fan casing 6 is started, and the fan blows air to the evaporator 5, and relatively low-temperature air is drawn in from the outside of the cabinet 1 to contact the evaporator 5 for rapid cooling. The cold air is dispersed into the cabinet 1 through the air flow to cool the equipment in the cabinet 1. At the same time, the air in the cabinet 1 will circulate to the outside of the cabinet 1 through the air exchange port 7, thereby increasing the ventilation effect in the cabinet 1 and the air circulation and heat dissipation effect on the surface of the condenser 4. Compared with the traditional integrated air conditioner, the device separates the condenser 4 and the evaporator 5 in the air conditioner, and is not limited to the size limitation of the integrated air conditioner, especially the condenser 4, which can be To cover most of the outside of the cabinet 1, greatly increase the heat dissipation effect, thereby increasing the treatment effect of the refrigerant, and ultimately increase the heat dissipation effect of the equipment in the cabinet 1.
