About Air Heat Exchanger

An air heat exchanger (radiator) is a device that exchanges heat between air and another medium. There must be a certain temperature difference on both sides. It can heat or cool the air to the required temperature state to achieve the purpose of heating and cooling the air. This type of equipment is commonly used in air conditioning systems, especially industrial centralized air supply drying and condensing systems.

Air heat exchangers (radiators) include air heaters and air coolers. The heater uses hot water, steam or thermal oil as the heat medium. The medium in the cooling pipe is mostly cooling water, chilled water or other refrigerants. When the cooling temperature drops below the dew point, the moisture in the air condenses, and the air cooler at this time is also called a condenser.

Working Principle

The working principle of the air heat exchanger mainly involves the exchange of heat. Its core is to help the outside air come into contact with the hot fluid through the fins and tube walls inside the equipment, thereby achieving heat exchange.

The working principle of air heat exchanger can be summarized as follows:

1. Air movement. The air on the heat source side and the cold source side flows through fans or other means. Through the flowing air, heat can be effectively transferred.

2. Heat transfer by conduction. During the flow of air, the metal plates or pipes on the heat source side and cold source side will contact the air and transfer heat to the air through conduction.

3. Convective heat transfer. In addition to conduction, air flow can also transfer heat through convection. Convection refers to the heat transfer of fluid during the flow process. Through the flowing air, heat will be transferred from the heat source side to the cold source side.

4. Radiation heat transfer. In addition to conduction and convection, radiation is also a way of heat transfer. The metal plates or pipes on the heat source side and cold source side will radiate heat and transfer it to the air through radiation.

In addition, the air heat exchanger also contains several parts such as a heat exchange system, a power system, a control system, and a filtration system. These systems work together to achieve gas circulation within the equipment and transfer heat to the gas through the difference in indoor and outdoor temperatures. exchange, thereby lowering the indoor temperature.
