Abstract

A surface cooler includes a base component, a plurality of first fins, and a plurality of second fins. The base component has a first surface, a second surface, and a first thermally conductive material. The plurality of first fins extends substantially perpendicular from the first surface and each first fin is characterized by a first height and a first width. The plurality of second fins extends substantially perpendicular from the first surface and each second fin is characterized by a second height and a second width. One or more fins of the plurality of first fins are disposed between a pair of adjacent fins of the plurality of second fins and an average first height of the plurality of first fins is lower than an average second height of the plurality of second fins. The plurality of fins reduces air drag and augments heat transfer capacity of surface cooler.
