Description
Summary:The results of studies of characteristics of heat-removing electrical insulating plates of different designs based on heat-conducting AlN and Al 2 O 3 ceramics and aluminum-oxide plates based on aluminum plates are presented. Thermophysical parameters of the heat-removing plates were assessed by measuring the temperature of p – n junctions of the photoelectric converters mounted on the plates with thermal load applied to them. It was found that the minimum overheating temperature of p – n junctions, 45°C, was observed at the supplied thermal power of 13 W, when the photoelectric converters were installed on the AlN ceramics. In photoelectric converters installed on the Al 2 O 3 ceramics, the overheating of p – n junctions was 49°C, while it reached 70°C on the aluminum-oxide substrate.
