A proton exchange membrane hydrogen fuel cell is a power generation device that can directly convert chemical energy stored in fuel into electrical energy through an electrochemical reaction. As long as hydrogen fuel and oxidant (generally air) are continuously supplied to the anode side and the cathode side, it can continuously output electric energy to the outside through oxidation-reduction reaction. A typical hydrogen fuel cell power generation system generally includes, in addition to a hydrogen fuel cell stack, a hydrogen gas supply subsystem, an air supply subsystem, a water heat management subsystem, an electrical management and control subsystem, and the like, and the main auxiliary system components include an air compressor, a humidifier, a cooling water pump, a hydrogen circulation pump, and the like.

In a hydrogen fuel cell system, filtration of the coolant is required to meet the requirements of the hydrogen fuel cell system.

Meanwhile, with the development of the hydrogen fuel cell technology, hydrogen fuel cell vehicles are more and more concerned, and the technology of the hydrogen fuel commercial vehicles gradually matures; however, due to the limitation of the space size of the hydrogen fuel commercial vehicle, the components of the hydrogen fuel cell are developed toward integration and simplification.

In order to achieve the above object, the utility model adopts the following technical scheme:

the utility model provides a pipeline type filter in a hydrogen fuel cell cooling system, which comprises a two-way pipe body and a filter element, wherein the filter element is nested in the inner cavity of the two-way pipe body; the filter element is hollow, the cooling liquid can penetrate through the shell of the filter element to enter the filter element, one end of the filter element is closed, and the other end of the filter element is open, a plurality of filter screens vertical to the axial direction of the filter element are arranged in the hollow filter element, and the filter screens are used for filtering the cooling liquid;

one end of the two-way pipe body is provided with a groove, one end of the filter element, which corresponds to the opening, protrudes outwards for a circle of lug boss, and the lug boss is welded with the groove arranged at one end of the two-way pipe body in a heat seal manner, so that the two-way pipe body and one end of the filter element are sealed;

when the filter is arranged in a pipeline of a hydrogen fuel cell cooling system, one closed end of the filter element is used as one end into which cooling liquid flows.

Further, bi-pass body and filter core are the cylinder, the central axial setting of filter core along bi-pass body.

Further, the peripheral diameter of filter core is less than the internal diameter of bi-pass body, certain distance has between the surface of filter core and the inner wall of bi-pass body. The cooling liquid can flow into the double-way pipe body and diffuse from the peripheral surface of the filter element to the filter element, so that the effective filtering area of the filter screen in the filter element is increased, and the flow resistance of the filter element is reduced. Furthermore, one end of the filter element which is closed can extend out of one end of the double-way pipe body which corresponds to the filter element.
