The air cooler is a kind of cooler, which is characterized by using air as a heat exchange medium for heat exchange, and the heat is taken away by the air, so it is also called an air cooler.
Generally speaking, the heat dissipation effect of an air cooler mainly depends on the heat exchange area and air volume of the radiator of its components. Simply: the same heat exchange area, the larger the air volume, the better the heat dissipation effect. The same air volume, the greater the heat exchange area. Larger, the better the heat dissipation effect. In terms of calling habits, it is also called oil cooler or air-cooled oil cooler, aluminum alloy plate-fin air cooler.
At present, air coolers, which are widely used at home and abroad, are made of aluminum alloy with good thermal conductivity, and the fluid channel and air channel are plate-fin structure. The core is made of vacuum brazing, and the fluid channel is provided with inner fins. piece. Compared with the traditional copper tube type, the heat exchange area per unit volume is greatly improved, which is 10-20 times that of the traditional copper tube type structure, and the heat exchange efficiency is good. It is often used as an auxiliary part of the hydraulic transmission system to cool the hydraulic oil to obtain the normal working temperature (range) of the hydraulic oil, improve the working stability of the hydraulic system and the service life of the components.
