AI Technical Summary

Technical Problem

The sealing design of existing ion exchanger filter elements leads to uneven flow of cooling liquid, increases pressure drop and reduces the performance of ion exchangers, and the seals are prone to damage.

Method used

The design employs an inclined sealing plane and a rotatable bayonet connection, combined with guide grooves and guide elements, to ensure proper positioning and sealing of the ion exchanger filter element within the housing, reducing turbulence, increasing the flow cross-section, and lowering pressure drop.

Benefits of technology

It improves the lifespan and sealing performance of ion exchanger filter elements, reduces turbulence and pressure drop, increases resin volume, ensures uniform media flow, and reduces the risk of seal damage.

Abstract

This invention relates to ion exchanger filtration devices and ion exchanger filter elements. An ion exchanger filtration device (100), particularly for a fuel cell system, comprises: a housing (102) including a cover (112) and at least one inlet opening (104) and at least one outlet opening (106) for a medium, the housing extending in an axial direction (80); and an ion exchanger filter element (10) surrounded by the housing, including one or more inlet ports (34) at an upstream end (20), and a circumferentially extending wall (32) surrounding a container (16) filled with ion exchange material (12), the wall including one or more outlet ports (18) at a downstream end (21) opposite the upstream end. The upstream end includes a sealing plane (60) providing a sealing contact with the housing, the sealing plane being inclined at an angle (70) relative to the axial direction.
