HEAT EXCHANGE DEVICE

摘要

A heat transfer device having a heat source for collecting waste heat from a heat- generating system, the heat transfer device having fins in which the shape o f the sides of the fins is preferably circular according to the general expression where , h is the heat transfer coefficient between the fin and th e surrounding fluid, k is the thermal conductivity of the fin material, , q o is the heat f low through the fin semi-base per unit depth and .theta.o is the difference between the temperatures of the heated surface and the surrounding fluid.
