Air Cooling

Forced air cooling



Air cooling is a way of cooling, that is, air as a medium to cool the heat source that needs to be cooled. Forced air cooling is a way to realize the cooling of heat source parts by increasing the flow of air. It is usually to increase the surface area of the heat source parts to be cooled, or to speed up the flow rate of air through the object per unit time, or to share the two methods. These two methods can achieve good heat dissipation performance.The former can increase the heat dissipation area by adding heat sinks on the surface of the heat source. Usually, the heat sinks are hung outside the heat source or firmly fixed on the heat source to make the heat dissipation more efficient. The latter is that fans (wind turbines) can be used to enhance ventilation and enhance the cooling effect. In general, fans with heat sink can greatly improve the cooling efficiency.

Forced air cooling heat sink is often used in internal combustion engine cooling, we can seeoutside of internal combustion engine on a car or motorcycle there are fins and an exhaust guard for forced air cooling, the fins are designed to increase the cooling area, and the exhaust guard is used to strengthen the air flow on the surface of the internal combustion engine so that  engine cooling fas to guarantee the normal operation.

In recent years, LORI thermal has strengthened the research and development of the application of forced air cooling technology, and realized the application of forced air cooling for the heat dissipation of wind energy converters, Suppressorsphotovoltaic inverters, Rectifiers,Regulator,SVG and other high power product.The air cooling heat sink structions have high power skived heatsink+ fan or high power skived heat sink+ heat pipe, which can greatly improve the heat dissipation efficiency.
