Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen energy fuel cells, in particular to a through-plate joint. Background Art

[0002] Hydrogen fuel cells are not limited by the efficiency of the Carnot cycle. The power generation efficiency can be as high as 40-50%, and the only product is water. It is extremely clean and efficient, and is an ideal engine system. The hydrogen fuel cell system is highly integrated, and the internal components have a large amount of heat. Usually, a cooling system is introduced into the system, and the fuel cell stack and various electronic and electrical components inside the system are exchanged with heat under the action of the coolant. Therefore, the heat exchange system of the fuel cell plays a vital role in the application of fuel cells.

[0003] In practical application areas (such as rail transit, stationary power generation, and other application scenarios), fuel cell systems often use system integration to integrate some components into a box to reduce the overall volume, adapt to various practical application environments, and have protective significance. The specific method used by the heat exchange system of the fuel cell system is to connect a radiator to the outside, and the radiator takes away the heat generated by the fuel cell system.

[0004] The connection method between the fuel cell system box and the external radiator affects the interaction between the system and the external environment. The interface to the outside world not only needs to meet the internal protection requirements, but also the connection and maintenance convenience of the cooling pipes, as well as the filtering requirements for large particles in the coolant.
