수소전기상용차 냉각순환시스템용 연료전지 열교환기 내압 해석 설계

다국어 초록 (Multilingual Abstract)

In order to confirm structural safety due to abnormal coolant high pressure of fuel cell cooler for fuel cell electric commercial vehicle cooling circulation system, internal pressure analysis was performed. When the fuel cell cooler PE side was pressurized, stress concentration occurred in contact with the heat transfer fin on the PE side and the plate. When the fuel cell cooler stack side was pressurized, stress concentration occurred from the curved portion inside the heat transfer fin on the stack side. In order to reduce the pressure drop of PE coolant in the fuel cell cooler, an improvement design was made to secure the flow path space by removing some of the heat transfer fins on the PE side. As a result of the internal pressure analysis of the improvement design of the fuel cell cooler, the stress concentration was similar to that of the primary design. As a result of internal pressure analysis of the fuel cell cooler, the maximum stress is below the tensile strength and yield strength of the material, and thus deformation and damage do not occur, so it is considered to be safe.
