WIPO Patent Application WO/2024/067362

A1

A particle filter (1000), the particle filter (1000) comprising a body (100), wherein the body (100) is internally provided with a plurality of inlet channels (110) and a plurality of outlet channels (120); the inlet channels (110) and the outlet channels (120) are arranged in an adjacent manner, the plurality of inlet channels (110) not being connected to each other, and the plurality of outlet channels (120) also not being connected to each other; the hydraulic diameter of the inlet channels (110) is greater than the hydraulic diameter of the outlet channels (120); the body (100) located between every two adjacent channels forms tube walls of the channels; and the tube walls of the plurality of channels, of which extension lines are located on the same straight line, are equivalent to each other in terms of thickness. The particle filter (1000) can use a traditional electrical discharge machine to produce an extrusion die, such that the production difficulty of an extrusion die which is used for producing the filter is reduced, thus facilitating a reduction in the production costs of the particle filter. Further disclosed is an extrusion die (2000) for the particle filter (1000).
