LIQUID COOLING SYSTEM FOR INTERNAL COMBUSTION ENGINE Russian patent published in 1995 - IPC

FIELD: engine engineering. SUBSTANCE: system has radiator and working wheel of the axial fan arranged downstream inside the space parallel the front of the radiator. The working wheel had the hub with blades arranged inside the fan coupled with the casing radiator. The radiator has central part arranged radially below the fan blades, periphery part arranged radially above the fan blades, and intermediate part arranged opposite to the fan blades. The hub of the working wheel is made up as a coaxial flow generating sleeve. The open end of the sleeve is arranged near the radiator. The space of the sleeve is in communication with the inlet of centrifugal passages made in the blades. The outlet of the passages is arranged on the periphery faces of the blades. The casing of the fan is made up as the inner part and outer part coupled with the radiator. The parts are separated with the space abutting against the periphery part of the radiator and is in communication with the ring-slot mixing chamber of the gas ejector. The active nozzle of the ejector is made up as the outlets of the centrifugal passageways of the blades. The ring-slot mixing chamber is defined by the shaped disks coupled with the casing parts. The inner part of the casing has the ring cut opposite to the outlets of the blade centrifugal passages. In addition, the inner part of the casing is made up as conical collectors from the side of the radiator. EFFECT: improved design. 2 cl, 1 dwg
