Abstract

An ion exchange filter assembly includes an ion exchange filter cartridge and a housing. The ion exchange filter cartridge includes an ion exchange filter for filtering a coolant. The housing includes a first section receiving the ion exchange filter cartridge and a second section for degassing the coolant. The first section is in fluid communication with the second section.

First claim

What is claimed is:

1. An ion exchange filter assembly comprising:
an ion exchange filter cartridge including an ion exchange filter for filtering a coolant;
a housing including a first section receiving the ion exchange filter cartridge and a second section for degassing the coolant, the first section being in fluid communication with the second section, the housing including a common, internal wall between the first section and the second section, the common wall defining a coolant exit opening for routing a portion of the coolant from the first section to the second section for degassing and a coolant return opening for returning the portion of the coolant to the first section after degassing.

2. The ion exchange filter assembly of claim 1 , wherein the common, internal wall is partially cylindrical in shape.

3. The ion exchange filter assembly of claim 2 , wherein the common, internal wall cooperates with an exterior sidewall of the first section to define a cylindrical filter containment region receiving the filter.

4. The ion exchange filter assembly of claim 1 , further comprising a conduit associated with the coolant exit opening, the conduit having an open end disposed above the coolant exit opening.

5. The ion exchange filter assembly of claim 1 , wherein the housing includes a first portion including the first and second sections and a second portion removably secured to the first portion, the first and second portions cooperatively defining a degassing chamber.

6. The ion exchange filter assembly of claim 4 , wherein the housing includes a first portion including the first and second sections and a second portion removably secured to the first portion, the first and second portions cooperatively defining the degassing chamber; and
wherein the conduit upwardly extends into the second portion of the housing.

7. The ion exchange filter assembly of claim 6 , wherein the conduit is generally L-shaped with a first arm horizontally extending from the common, internal wall and a second arm upwardly extending from the first arm.

8. The ion exchange filter assembly of claim 1 , wherein the ion exchange filter assembly is configured to operate with a vehicle fuel cell system.
