[0002] The oil filter, also known as the oil grid, is used to remove impurities such as dust, metal particles, carbon sediments and soot particles in the oil to protect the engine. Oil filters are divided into full-flow and split-flow types. The full-flow filter is connected in series between the oil pump and the main oil channel, so it can filter all the lubricating oil entering the main oil channel. The split-flow filter is connected in parallel with the main oil channel and only filters part of the lubricating oil delivered by the oil pump.

[0003] A new type of external oil filter is disclosed in the Chinese utility model patent application disclosure specification CN202220450400.2. Although the new type of external oil filter can be installed through the external threaded cylinder, the lower joint is threadedly connected to the inside of the double threaded cylinder through the external threaded cylinder, and the fitting plate fits into the inside of the fitting groove, making it easier to disassemble and clean the lower joint and the cylinder body.

[0004] Although the external oil filter can cool the mechanism through the oil cooler, it lacks a heat dissipation structure during the filtering process, so that the heat dissipation effect of the oil filter is relatively poor during operation, and it is difficult to achieve dual heat dissipation operation with the oil cooler.

A filter screen is fixedly installed at the lower part of the inside of the filter housing, and a filter element is placed above the filter screen. An external threaded pipe is installed at the bottom of the filter housing, and the bottom end of the external threaded pipe is connected to an oil outlet pipe.

[0009] Preferably, a second flange is welded to the top of the filter housing, and a sealing gasket is embedded in the top surface of the second flange, a first flange is installed on the top of the second flange, an oil inlet pipe is connected to the center of the top of the first flange, and a screw is installed between the first flange and the second flange.

[0010] Preferably, the annular fins are longitudinally equidistantly distributed outside the filter housing, and the annular fins are connected to the plate-like fins by electric welding.

[0011] Preferably, the externally threaded pipe is threadedly connected to the filter housing, and the bottom diameter of the filter housing is consistent with the top diameter of the oil outlet pipe.

[0012] Preferably, a detachable structure is formed between the oil inlet pipe and the second flange through the first flange and a screw, and the first flange and the second flange have the same shape and specification.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0014] 1.
