(10) An improvement of the solution of the present invention is as follows: a new structure of a new main oil channel (the end-face inclined-hole main oil channel 8)+a base auxiliary oil channel (the auxiliary oil channel 609) is designed in the oil filter base 6. Specifically, a process hole oil channel and bolt plug blocking structure on a back end is improved to the end-face inclined-hole main oil channel 8 on a front side of the oil filter base 6, and the base auxiliary oil channel that is in an original aluminium base (the oil filter base 6) is improved to the auxiliary oil channel 609 that is disposed on the face, in contact with the oil cooler 9, of the oil filter base 6. The auxiliary oil channel 609 on the upper end face (the face in contact with the oil cooler 9) of the oil filter base 6 is used as a carrier for connection, to implement oil auxiliary supply of an engine and accelerate to cool a connection effect with an oil passage.
