Description

Technical Field

[0001] The present application relates to the technical field of automobile radiators, and in particular to an anti-deformation filter used in an oil cooling system of an automobile radiator assembly. Background Art

[0002] In the oil cooling system of the automobile radiator assembly, the pleated annular filter is widely used in the oil cooling system of the automobile radiator assembly and other occasions requiring high-efficiency filtration because of its unique structure, which can significantly increase the filtration area in a limited space, thereby improving the filtration efficiency. This filter is usually installed at the oil inlet of the oil cooler to ensure that only clean oil can enter the cooler, avoid impurities blocking the internal channel, and thus ensure the normal operation of the cooling system.

[0003] Although this design has significant advantages, it also has some limitations in practical applications. For example, under high pressure or vibration conditions, the filter screen may deform due to the design of stepped annular pleats, resulting in the risk of filtered oil leakage. This not only reduces the filtration efficiency, but may also cause damage to the engine.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0005] In order to solve the problem that the pleated annular filter screen has poor stability and is easily deformed during use, the present application provides an anti-deformation filter screen.

[0006] The anti-deformation filter provided in this application adopts the following technical solution:

[0007] An anti-deformation filter screen comprises a filter screen, a reinforcement frame and a support bar;

[0008] Wherein, the filter screen is used for filtering fluid;

[0009] A plurality of the reinforcing frames are concentrically arranged on the bottom surface of the fold depressions of the filter screen to enhance the overall strength;

[0010] A plurality of the support bars are respectively arranged between two pleated outer walls of the filter net to enhance the anti-deformation strength of the pleats.

[0011] Preferably, the filter screen comprises an annular filter screen and a fixed edge, and the fixed edge is arranged on the outside of the annular filter screen to ensure the positioning and sealing of the annular filter screen in the housing.

[0012] Preferably, the reinforcement frame includes two reinforcement ribs arranged on the pleated surface of the annular filter screen, and a plurality of connecting blocks are arranged between the two reinforcement ribs.

[0013] Preferably, the support bar is arranged between two pleated surfaces on the annular filter screen, and the support bar is parallel to the axis of the annular filter screen.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] Through the coordinated use of the filter screen, reinforcement frame and support strips, the reinforcement frame is used for annular radial support to enhance the overall circular centrality and prevent the annular folds from deforming. The annular filter screen is axially supported by the support strips to prevent the end face from collapsing and deforming. The reinforcement frame is used to form adjacent annular folds into a whole, thereby improving the deformation resistance of the annular filter screen and preventing oil leakage caused by deformation of the annular filter screen during use. Compared with the prior art, the method has the effects of high support strength and simple structure. BRIEF DESCRIPTION OF THE DRAWINGS
