Integrated deionizing device

Abstract

The invention discloses an integrated deionizing device. The integrated deionizing device comprises an expansion kettle, a filter element assembly, a conductivity tester and a control valve, by adopting the technical scheme, the filter element assembly is provided with a plurality of small filter elements, and the filter element via holes matched with the small filter elements and the kettle sealing cover matched with the filter element via holes, so that the filter elements can be easily replaced, additional dismounting tools are not needed, the operation is simple, the requirement on the quality of operators is low, and the cost is low. The problem that cooling liquid flows out due to replacement of the filter element can be solved, and the maintenance cost is greatly reduced; the small filter element can be directly placed in the existing expansion kettle, and a new mold of the expansion kettle does not need to be opened, so that the design cost is further reduced; meanwhile, the conductivity tester and the control valve are both integrated on the expansion kettle, the structure is more compact, and the occupied installation space is reduced.

Description

technical field [0001] The invention relates to the technical field of fuel cell vehicle cooling systems, in particular to an integrated deionization device. Background technique [0002] Fuel cell vehicles use fuel cells to consume reactants and generate electric energy as all or part of the power source to drive the vehicle forward. In recent years, with the increasing emphasis on environmental protection and clean energy, coupled with the advantages of fuel cells with high power and no pollution, the application prospects of fuel cell vehicles are widely optimistic. [0003] The fuel cell will release a lot of heat during operation, therefore, a special cooling system must be configured to dissipate heat from the fuel cell. Currently, the most popular heat dissipation method is liquid cooling, that is, the cooling liquid is powered by a water pump and flows through the bipolar plates inside the fuel cell to remove heat. During the operation of the fuel cell, a high volt...

Problems solved by technology

[0004] However, due to structural design problems, the existing deionizer cannot replace the filter element, and the deionizer must be replaced as a whole. Therefore, the water inlet pipe needs to be opened before the deionizer can be disassembled and installed, which will lead to expensive fuel cell dedicated Coolant loss, not only high maintenance cost, but also complicated operation, time-consuming and labor-intensive

[0005] Therefore, a deionizer with a replaceable filter element has emerged on the market, but due to structural design problems and the traditional structure of the deionizer filter element, the deionizer has to be made very large, resulting in the deionizer The requirements for installation space are extremely high, which is not conducive to the integration of OEMs
