Wave Soldering *** Industrial Air Cooler

The air cooler is an environmentally friendly and energy-saving air-cooled device launched by Shenzhen Chuanbenster Refrigeration Equipment Co., Ltd. for industries such as wave soldering machines, spraying, reflow soldering, assembly lines, laboratories, foundry, home appliance industry, and food industry. Using air as the medium, it can quickly cool the space and products in a short time. It is an ideal industrial refrigeration device after air conditioners.

I. Working principle of the air cooler

According to the principle of the refrigeration system, the low-temperature and low-pressure liquid refrigerant exchanges heat with the surrounding water in the evaporator. The evaporator absorbs the heat of the water and evaporates into a low-temperature and low-pressure gas. The temperature of the refrigerant remains unchanged during the evaporation process. The low-temperature and low-pressure gaseous refrigerant enters the compressor. After being compressed by the compressor, it is compressed into a high-temperature and high-pressure gas, and then enters the condenser. In the condenser, it exchanges heat with the indoor medium. Part of the heat of the high-temperature and high-pressure gas is absorbed by the medium, and the temperature of the medium rises. The refrigerant releases heat and becomes a high-temperature and high-pressure liquid in the condenser. The temperature remains unchanged during the condenser process. Then it enters the expansion valve for throttling. Throttling is a process of rapid cooling. The refrigerant becomes a low-temperature and low-pressure liquid. After this process, the refrigerant enters the evaporator again for heat exchange and evaporation, thus realizing the entire process of the refrigeration system. This cycle is continuous, so that the water can be continuously cooled. Then the cold air is blown to the place where cooling is needed through the blower.

II. Classification of air coolers

1. According to the cooling (heat dissipation) method

A. Water-cooled air cooler: (Shell and tube type) The condenser is equipped with a cooling tower for heat dissipation.

B. Air-cooled air cooler: (Finned type) The condenser dissipates heat through the fan of the machine itself.

Selection of air coolers: Generally, select the appropriate water-cooled air coolers and air-cooled air coolers according to the cooling capacity (air volume and temperature).The characteristics of air-cooled type: It is named after the heat dissipation method. It contains an insulated water tank and a water pump inside the fuselage. There is no need to add an additional cooling tower for heat dissipation. It is very convenient for installation and movement. However, it requires good ventilation in the workshop for the working environment. Otherwise, it will directly affect the cooling effect.The characteristics of water-cooled type: Water-cooled air coolers need to be additionally equipped with a cooling tower and a water pump to extract hot water for heat dissipation in order to achieve a better cooling effect.
