ABSTRACT:
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 of the sides of the fins is preferably circular according to the general expression(x-1γ)2+(y-ργ)2=1γ2,whereγ=hk,h is the heat transfer coefficient between the fin and the surrounding fluid, k is the thermal conductivity of the fin material,ρ=qok⁢⁢θo,qois the heat flow through the fin semi-base per unit depth and θ0is the difference between the temperatures of the heated surface and the surrounding fluid.
