The working principle of dry cooler is mainly based on the principle of heat exchange. Specifically, there is a circulating refrigerant flowing through the pipes inside the dry cooler, and these pipes are usually designed as a structure with efficient heat dissipation. When the high-temperature refrigerant flows through these pipes, the fan or natural wind outside the pipe will blow the air over the surface of the pipe to form a heat exchange.
In this process, the refrigerant transfers heat to the outside air through the pipe wall, so that the temperature of the refrigerant is reduced, thereby achieving the cooling effect. The outside air warms up because it absorbs the heat of the refrigerant, and is then discharged or dissipated naturally.
This heat exchange process is carried out continuously, and the refrigerant circulates in the dry cooler, continuously releasing heat, thereby keeping its temperature at a low level. In this way, the dry cooler can effectively reduce the temperature of the liquid and achieve the purpose of cooling.
It should be noted that the dry cooler does not consume water during operation, so its water-saving performance is very obvious. At the same time, since the heat exchange is carried out through the air, the dry cooler will not produce water mist or water droplets during operation, so that it can also be used in some environments with high humidity requirements.
In general, the dry cooler uses the principle of heat exchange and the temperature difference between air and refrigerant to achieve cooling effect. It is an efficient and energy-saving cooling device.
