FIELD: electricity.
SUBSTANCE: converter includes power electrical component (22) that can participate in conversion of electrical current and closed cooling circuit (14) containing a two-phase heat carrier medium, the first heat exchanger (30A, 30B, 30C, 30D) adjoining the above said power electrical component (12), the second heat exchanger (38) that can remove heat of the heat carrier medium beyond the cooling circuit limits, and actuating devices of circulation of the heat carrier medium in cooling circuit (14). The first heat exchanger includes a capillary evaporator containing a capillary channel that can provide full evaporation of the heat carrier medium supplied in a liquid state on the level of a meniscus lens installed in the channel and separating liquid and vapour phases of the heat carrier medium and return the heat carrier medium fully in a gaseous state. The heat carrier medium circulates in cooling circuit (14) under action of pressure created on the level of the liquid/vapour boundary line in the capillary evaporator for formation of a capillary suction circuit.
EFFECT: reduction of overall dimensions and easier maintenance.
