HEAT EXCHANGE IN COMPOSITION SYSTEMS WITH METAL SURFACES OF HEATED STRESSED OBJECTS
The process of the formation of contact thermal resistances in composite systems of heat stressed technical objects is considered. The dependence of thermal resistance in the zone of mutual contact of metal elements of composite systems is experimentally established. The possibility of thermal control by introducing into the contact zone of the metal surfaces of composite systems of fillers of various nature in the form of gaskets, allowing, in particular, to increase the contact thermal resistance, and thus act as a heat insulating screen, is justified. The dependence of the thermal resistance of the transition on the thermal conductivity of the aggregate, its thickness and temperature in the contact zone is also established. The increased efficiency of the use of multilayer thermal insulation is shown.
