Noren, D W

A heat exchanger assembly is described for cooling the interior of a closed cabinet containing electronic components or the like, comprising: a finned heat pipe core including: a plurality of spaced heat pipes positioned in at least one row, a plurality of spaced fins which are provided with colinear apertures through which each of the plurality of heat pipes can extend, the heat pipes being secured to the fins; affixing means for securing the finned heat pipe core to an associated cabinet; and, a pair of fans, one being operatively connected with each end of the finned heat pipe core, one of the fans, and an associated first end of the heat pipe core, being in contact with only the air inside the associated closed cabinet, the other of the fans and an associated second end of the finned heat pipe core being in contact with only the ambient air outside the associated cabinet, and wherein the fins have a spacing and a thickness which is sized to fit the performance curve of the fans wherein the fans each have a capacity of approximately 100 CFM (cubic feet per minute) and wherein the finned heat pipe core is optimized for the fans such that approximately fourteen fins are provided per inch of heat pipe length with each of the fins being approximately 0.008 inches in thickness, whereby the finned heat pipe core and the pair of fans are capable of transferring at least 200 watts of heat when the temperature inside the associated cabinet is approximately 20/sup 0/C above the ambient temperature.
