EXPERIMENTAL STUDY OF A DEVICE FOR COOLING ELEMENTS OF RADIO ELECTRONIC EQUIPMENT OPERATING IN THE INTERMITTENT THERMAL LOADS MODE
Annotation
A device for cooling elements of radio-electronic equipment operating in the mode of intermittent thermal loads is considered. The device uses melting working substances with an additional air heat sink due to fan units. An experimental stand is described, results of the device field tests are presented. Time dependences of the container shell temperature during melting and solidification of the working substance, as well as duration of complete melting (solidification) of the working agent caused by supplied (removed) heat, are presented. It is determined that the use of fan assemblies makes it possible to reduce the substance solidification time by about 1.7 times in relation to the case of natural heat exchange with the environment by means of a copper radiator. According to estimates carried out, the discrepancy between the experimental and calculated data is 8 %.
