A theoretical analysis of their performance characteristics shows that they have nearly the heat transport capability expected by scaling down from conventional heat pipes.
Webb2 feb. 2011 · where is the rate of heat transfer, η l the liquid viscosity, A w the cross sectional area within the wick, K the permeability of the wick, and ρ l the liquid density.. … WebbIn forced convection, air or water is forcibly moved across the body surface (such as in wind or wind-generated water currents) and efficiently removes heat from the body. Convection is a very efficient way of heat transfer because it maintains a steep temperature gradient between the body and surrounding air or water.
