ABSTRACT:
An improved heat exchanger (10) has a heat sink (22) with fins (24) having a very high heat transfer coefficient structurally associated with a compact, high air velocity air moving means (14). Air moving means (14) of the invention employs a backward curved impeller (16) driven by a compact planar dc motor (50) adapted to yield higher than normal impeller speeds with superior thermal transfer performance.
