Heat Exchangers

Air-to-air heat exchanges are a closed loop cooling system which employs the heat pipe principle to exchange heat from an electrical enclosure to the outside. Heat pipes have a liquid refrigerant inside sealed tubes.

The Stratus design has a top-to-bottom enclosure air flow pattern with maximum separation of the inlet and outlet. This design pulls the hottest air from the top of the enclosure and returns the cooled air from the bottom of the heat pipe to the enclosure. The air flow on the ambient side is bottom in, top out, so that the hotter discharge air moves up and away rather than being recirculated. The units use aluminum end plates and baffles which improve conduction and reduce corrosion for longer life.
