Abstract

Fundamental problems of heat transfer in most commonly used solar heat collectors have been presented. A short survey of different types of collectors and possibilities of their application have been given. For consideration of heat transfer problems two representative types of collectors have been chosen: a flat-plate collector and a parabolic focusing collector with a cylindrical absorber of circular cross section. Various forms of thermal balances have been presented and the analysis of complex heat transfer processes by radiation, convection and conduction has been carried out. The influence of heat transfer phenomena on thermal power and collectors efficiency has been studied with particular emphasis given on thermal processes joined with geometrical ontics and properties of materials in use.
