Please tell me, what is an air cooler?

Generally, a refrigerator is used to cool the circulating water, and then the air is cooled through plate exchange and air heat exchange, and then blown to your device through a fan, allowing your materials to stay on a retention surface and exchange heat with the air. This retention surface can be either vertical or horizontal. Mainly depends on the nature of your material. I have seen air cooling using compressed air, usually used in the chemical industry. There is also an ordinary fan air cooling, which is used by a zipper factory. The air supply volumes of the two forms are different, and the refrigerator can also operate in ordinary air-conditioning working conditions (7 degrees) and low-temperature working conditions (1 degree or lower). Please refer to the book "Air Cooler Technical Questions and Answers"

Is it just like the principle of an electric fan? It only consumes electricity when used

Air cooling, as the name suggests, means "air cooling"! It is one of the most common chemical equipments

Air cooler is also a type of heat exchanger, it should be called air heat exchanger! Induced air type: The tube bundle is located on the suction side of the fan. Since the air duct blocks the heat exchange fins very well from sunlight, wind, rain, and snow, the induced draft air cooler has stable heat exchange performance. At the same time, it has the characteristics of even air volume distribution, less heat circulation, less staining and low noise. blast type: The tube bundle is located on the exhaust side of the fan. This structure is very convenient for maintenance, and the fan motor is always in a cooler air environment, which allows the device to have a higher temperature for the process medium to enter, and has a longer service life. Humidification air cooler: A combination of humidification unit and air cooler is a good solution in some dry areas and hot weather. The ambient air is cooled by direct contact with the water in the humidification unit thereby reducing the medium temperature.

Does the air go through the tube side or the shell side?

There is no tube side or shell side in the air cooler.

To be precise: Air cooler is a form of heat exchanger and a device that uses air under natural conditions to cool the medium. Generally without shell, it is often used in areas lacking water or areas where it is inconvenient to bring water (such as: Diesel locomotives, etc.), the tube side material is selected according to the media performance, and a fan is generally used for air supply. Two years ago, only three units participated in bidding for large power plants in the north.: A German company in Wuhu, an American company in Shanghai, and a domestic company in Harbin.

The cooling medium in the heat medium tube path is air, right?

Air cooling is a heat exchanger in which the cooling medium is air. Since the air heat transfer coefficient is small, in order to improve the heat transfer efficiency, external fins are often added outside the tube. It is suitable for situations where the outlet temperature of the heat medium is 15-20 degrees Celsius higher than the air inlet temperature. Air cooling generally occupies a larger area. There are many forms of fins. There are also many classification methods. The above details can be found in the corresponding books on our Haichuan Forum.
