Thermal Design: Basic Stages, Problems and Solutions

This paper discusses the stages in the development of a project in the field of thermal design and how to reduce the possible risks in the initial stage of product development for thermal engineers. An approach for evaluating the thermal efficiency of three test structures of printed circuit boards through CFD modelling and simulations of heat transfer processes is proposed. The thermal regime of a COB LED module with a cooling radiator designed for it is predicted by CFD simulation. Experimental measurements with a prototype of the COB LED module are performed, which show good compliance with the results in the simulations.
