AI Technical Summary
In hydrogen fuel cell systems, deionizers are prone to resin breakage and leakage during use, and adding filters can increase system flow resistance.
The expansion tank is equipped with filter plates and filter plate slots. The filter plates have filter holes and filter screens, which are connected by hot-melt welding. The filter plates can be inserted and fitted together, and the filter plates can be disassembled for easy maintenance and replacement.
It effectively prevents resin debris from entering the cooling pipes, maintains smooth water flow, reduces maintenance costs, and improves system insulation.
