Теплоотводящие Электроизолирующие Платы Для Фотоэлектрических Преобразователей Концентрированного Солнечного Излучения

Abstract

In the article the results of investigation of characterics of electro insulated heatsinks of different design are presented. For the material of the heatsinks AlN and Al2O3 ceramics along with alumina were chosen. Thermal characteristics of the heatsinks has been studied by measuring temperature of p-n junctions of solar cells mounted on heatsinks under thermal loading. The minimum overheating temperature of p-n junction was 45°C with input thermal power equal 13 W, when solar cells were mounted on AlN ceramic. In case of using Al2O3 ceramic and alumina heatsinks the temperatures were 49°C, and 70°C respectively.
