Feasibility demonstration of effective geometry local heat load radiator

The problem of optimization calculation of the geometric characteristics of a fined heat-exchange surface with a local heat source under conditions of natural convection is considered. The solution was obtained for the condition of the maximum specific volumetric heat transfer capacity. An engineering technique is proposed for taking into account the local nature of the application of heat load. The design characteristics are introduced in function of temperature head, fin length and thickness of the radiator foot.
