Air to air heat exchangers use an innovative heat pipe technology that is simple, effective, and reliable. It's ideal for situations where cooling is required for sealed enclosures when alternative methods of cooling, such as filtered fans or air conditioning, are not desirable or practical.
The heat pipe, the heart of an air to air heat exchanger, uses the evaporation of a refrigerant liquid to transfer heat from the bottom to the top of the heat pipe, where the heat is discharged to the ambient air. Aluminum fins are attached to the pipe to improve the conduction of heat; a vertically mounted tube simplifies the design, increases capacity, and ensures reliability. The only power required is for two air circulation fans: one to circulate cool air to the electrical enclosure and the other to remove hot air from the top of the heat pipe and discharge this heat to the environment.
Here are several reasons why you should consider heat pipe technology.
