Abstract
The present invention provides a coolant demineralizer for a fuel cell vehicle, which removes ions released from coolant of a fuel cell stack. In preferred embodiments, the present invention provides a coolant demineralizer configured to reduce the occurrence of differential pressure due to an ion resin layer such that coolant can smoothly flow through a filter member, thereby increasing the effect of filtering ions and improving the efficiency of use of ion resin.
Claims7
A coolant demineralizer for a fuel cell vehicle, the coolant demineralizer comprising:
- a housing including an inlet port formed in a center of one end of a housing main body and an outlet port formed in a center of a housing cap assembled at an opposite end of the housing main body;
- and
- a filter member, in which an ion resin is filled, including an inlet formed at one end of the filter member and directly connected to the inlet port such that coolant is introduced therethrough directly into the filter member and an outlet formed on a side of the filter member such that the coolant passing through the ion resin is discharged from the side in a radial direction,
- wherein the coolant demineralizer further comprises a flow chamber connected to the outlet port of the housing and formed around the periphery of the filter member in the housing such that the coolant is discharged from the filter member through the outlet in a radial direction toward the flow chamber, then passes through the flow chamber and then discharged from the flow chamber to the outlet port, and
- wherein the inlet includes a planar mesh screen disposed horizontally below a lower end of a vertically oriented tubular side wall of the filter member, the planar mesh screen having an inner surface that contacts the ion resin, and the tubular sidewall having a lower half that is imperforate and an upper half that includes the outlet having a plurality of outlet openings that are covered by a mesh net with an inner surface contacted by the ion resin.
A coolant demineralizer for a fuel cell vehicle, the coolant demineralizer comprising:
- a housing comprising an inlet port and an outlet port;
- a filter member, in which an ion resin is filled, the filter member comprising, (i) an inlet connected to the inlet port such that coolant is introduced therethrough directly into the filter member and (ii) an outlet such that the coolant passing through the ion resin is discharged therethrough;
- and
- a flow chamber through which the fluid flows after being discharged from the filter member, and
- wherein the inlet includes a planar mesh screen disposed horizontally below a lower end of a vertically oriented tubular side wall of the filter member, the planar mesh screen having an inner surface that contacts the ion resin, and the tubular sidewall having a lower half that is imperforate and an upper half that includes the outlet having a plurality of outlet openings that are covered by a mesh net with an inner surface contacted by the ion resin.
