FIELD: electronics. SUBSTANCE: for provision of heat removal from surface under action of concentrated energy fluxes with density exceeding 5·103 W·cm-2 electric discharge is initiated on irradiated surface with thermal autoelectronic emission from nonexpendable cathode in which capacity irradiated element of structure is used. Inertia-free removal of heat irradiated surface is carried out as a result of emission cooling of cathode. Energy is transferred with electrons to auxiliary electrode-anode located close to irradiated surface. In case of operation of chemically active pair (surface - environment) gas inert to material of surface layer of irradiated element of structure is fed to discharge zone at working temperature of cathode. For operation in vacuum microprotrusion are made on irradiated surface. To achieve maximum high densities of removed power irradiated material has emission-active components. EFFECT: improved efficiency of heat removal. 4 cl, 3 dwg
