What Is Air Cooling?

Air cooling is a kind of cooling method, which uses air as a medium to cool objects that need to be cooled. Usually it is to increase the surface area of the object to be cooled, or to increase the rate of air flowing through the object per unit time, or to use the two methods together. The former can be achieved by adding a heat sink on the surface of the object. Usually, the heat sink is hung outside the object or fixed on the object to make the heat dissipation more efficient. The latter can use fans (fans) to enhance ventilation and enhance cooling effects. In most cases, adding cooling fins can greatly improve the cooling efficiency.

At present, the number of large-scale public buildings in cities is gradually increasing, and the application of centralized air conditioning is becoming more and more common. As the core cold-source production part of the operating part of centralized air-conditioning systems,

Motor vehicle

Air cooling is used to cool internal combustion engines, especially those of aircraft, because the coolant is always available and the temperature is right to ensure efficient cooling. When many internal combustion engines are together, they are called water-cooled internal combustion engines, usually cooled by air passing through a radiator or heat exchanger.

Cars that use air-cooled engines are relatively rare. One of the most common examples is horizontal-to-horizontal engines, which have been used extensively by Porsche. Notable old models include the Volkswagen Beetle and related models Citroen 2CV, Chevrolet Corvair and Porsche 911.

Turbine engine

Gas turbine engines (such as turbofan engines, turbojet engines, etc.) include turbines that allow the hot gases in the combustion chamber to be exhausted. When necessary, cooler turbine rotor blades are vented from the compression system to prevent them from melting.

Electronic component

Air cooling technology is widely used in CPU cooling, because the computer's CPU processor generates a lot of heat, and if it is not cooled in time, it will damage the CPU and other electronic components. In this case, air as an insulator is also one of its advantages. But in the future, if

CPU cooling

The semiconductor CPU processor generates too much heat, so the air-cooling capability becomes difficult, and this method will be abandoned or new CPUs will appear.

industry

Many industrial processes require air as a direct or indirect cooling medium. Air conditioning is a commonly used air treatment process. It is used in a house or an entire building to cool the air so that the occupants are in a comfortable environment. The air is usually cooled with chilled water or salt water, and then the heat is transferred to the outside by a medium. A water-air heat exchanger driven by a fan is generally used to discharge heat to the atmosphere. There are also common examples around, such as some high-tower building power stations use air cooling technology on a large scale.
