The KOOLEX passive Cover Heat Exchanger operates with two forced air circulation loops that are not connected thereby allowing sealed operation.
This system cycles air into the CHE where it passes over fins in the passage reducing the temperature of the fins which removes the heat. On the inside loop, the air in the case is brought into the CHE raising the temperature of the fins. The heat is passed from the inside loop to the outer loop via the fins (passive connection). The heat dissipation capability depends on the position of the case (stand alone, positioned against wall, stacked). It works most effectively when there is a temperature differential between the inside and outside of at least 20°C.
