INTERNAL COMBUSTION ENGINE COOLING SYSTEM UNIT Russian patent published in 2024 - IPC F02B77/13 F01P11/12 B60K11/06 

FIELD: machine building.

SUBSTANCE: invention can be used in cooling systems of internal combustion engines. Internal combustion engine cooling system unit comprises fan (2) and guide screen (1) from noise-absorbing material. On the surface of guiding screen (1) symmetrically relative to the fan rotation axis there are active intake openings (4) of the engine block-crankcase blowing, having a shape elongated in the vertical direction, and smoothly changing into guide channels with a variable cross section. In the upper part of guiding screen (1) there is opening (5) of a branch pipe of the turbo compressor and opening (6) of a branch pipe for supply of cooling liquid to the upper radiator tank. Contours of guide screen (1) coincide with internal contours of internal combustion engine nosing elements.

EFFECT: intensified heat release from engine crankcase surface.
