ABSTRACT:
A heat exchanger for cooling enclosures, typically electronic enclosures, has a box with a heat pipe type exchange element and upper and lower fan units. A novel element holder and box structure and arrangement of components provides for safety, NEMA-12 sealing, easy access and cleaning without tools, and enables the exchanger to be inverted end-for-end and mounted either on the inside or outside of the exchanger while providing a cover that easily comes off for service. The exchanger has an ambient fan and motor and a heat load fan and motor normally inside the box, and both fan and motors and the exchanger are movable to alternative positions for service. A method of servicing a heat exchanger is provided wherein two fans and motors, and a heat exchanger sequentially are unlocked and moved to alternative service positions.
