First, the air enters the heat exchanger. When the air enters the heat exchanger, it will be driven by the fan, forming a airflow. In this process, the air will carry heat into the heat exchanger.

Second, heat exchange of heat exchange tube and heat sink. Heat exchange tube and heat sink are the core components of air heat exchanger. The heat source air flows inside the heat exchange tube, and the cooling air flows on the heat sink. Through the design of the heat sink, the contact area between the air and the heat sink can be increased, thereby improving the heat transfer efficiency. When the heat source air is in contact with the air, heat is transferred from the heat source air to the cooling air, causing the cooling air to warm up and the heat source air to cool down.

Three, heat release. After the heat exchange between the heat exchange tube and the heat sink, the temperature of the cooling air increases, while the temperature of the heat source air decreases. The cooling air will carry the heat away, making the heat source air cooler. In this way, heat transfer and temperature regulation are achieved.

The working principle of air heat exchanger makes it widely used in many fields. For example, air heat exchangers can be used for heat dissipation of automotive engines, heat recovery in industrial production, and air treatment in some special environments.

A water-to-air heat exchanger is a system that has two heating systems into the air, passing the temperature of the water within the system and cooling the air. In these systems as a transfer device, as long as the temperature of the water is allowed to heat or cool, then force the air through the fan. Variations of this system can be found in a variety of fields. Sometimes, such systems are used for heating and cooling in homes. Air heat exchangers for water usually use water or other liquid to pass through a coil system. In turn, whatever the temperature in the coil is then transferred to the outside air, usually by the device's induction system, it is allowed to be transferred to a collection area, and then it can be forced into the system within the coil's surrounding temperature exit into the environment by a fan. These systems can be used to heat or cool the temperature of the air because they disperse and are directly related to the temperature of the fluid through which the coil operates.
