FIELD: power industry.
SUBSTANCE: fluid medium supply control device to the unit (48), such as the heat exchanger, contains the fluid medium distributor, installed in the fluid medium loop and contains the slide valve, configured to move between two positions, in the first of which it provide the fluid medium circulation in the unit, and in the second one it prevents the fluid medium circulation in the unit. The device also contains tapering with streamline flow in the fluid medium loop, made at the distributor inlet, and the distributor slide valve moving facility of the fluid medium between its two positions by the fluid medium pressure loss in the streamline flow tapering.
EFFECT: invention makes possible to increase the oil cooling efficiency.
