Abstract
Statement of the problem. In modern radio-electronic equipment, there is an increase in the heat generation density with a decrease in the size of devices, which requires the development of effective heat dissipation systems. Traditional metal radiators have high thermal conductivity, but their use is limited by the complexity of manufacturing and high cost in small-scale production. Additive technologies are a promising area, but the effectiveness of polymer and composite radiators has not been sufficiently studied.
Purpose. Experimental and theoretical study of the heat dissipation efficiency of radiators made using additive technologies, with an assessment of the influence of material and design features on thermal resistance.
Results. A comparative study of radiators made of PLA, PLA with copper filler, PETG composite material with carbon filler (PETG CF), and a sealed hollow structure with liquid coolant was conducted. It was found that the highest efficiency is achieved with the use of PLA.
