COMPACT RADIATOR FOR AN ELECTRONIC DEVICE

摘要

A compact radiator for a coolant used in cooling an electronic device, including inlet and outlet headers, a plurality of parallel fiat tubes defining coolant flow paths between the inlet and outlet headers, and serpentine fins between adjacent tubes. The tubes have a minor dimension in the range of 0.75 mm to 1.2 mm, and the fins have a height in the range of 3 mm to 7 mm. Particularly advantageously, extruded aluminum tubes have a minor dimension of 0.75 mm to 0.85 mm, the fin height of 3.0 mm to 3.25 mm, a tube major dimension on the order of 28 to 32 times the tube minor dimension, and a wall thickness of 0.15 mm to 0.25 mm.
