Title:
ENGINE OIL COOLING STRUCTURE OF ENGINE
Document Type and Number:
WIPO Patent Application WO/2024/027442
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of engines, and provides an engine oil cooling structure of an engine, which solves the technical problem that existing engine oil cooling structures are less prone to ensure the final flow of low-temperature engine oil to friction pairs. In the present engine oil cooling structure of an engine, the engine comprises a crankcase (7). The crankcase (7) is provided with a columnar oil filter mounting chamber (1). The cooling structure comprises a water channel (2), a water inlet (21) of the water channel (2) being communicated with a water pump (3). A main oil passage (4) is further provided in the crankcase (7), and a heat conduction thin wall (71) is further provided on the crankcase (7), the oil filter mounting chamber (1) being formed in an inner chamber of the heat conduction thin wall (71). The oil filter mounting chamber (1) is communicated with the main oil passage (4). The water channel (2) is arranged around an outer side wall of the heat conduction thin wall (71), a water outlet of the water channel (2) being communicated with a cooling water path (5) which is in the same direction as the main oil passage (4) and is arranged adjacent to the main oil passage (4). The present engine oil cooling structure can save the cost while reducing engine oil temperature.
