Description
Technical Field
[0001] The utility model relates to the technical field of fuel cell system structural components, in particular to an integrated joint for a fuel cell intercooler humidifier. Background Art
[0002] The air system in the fuel cell engine system includes air compressor, intercooler, humidifier, bypass valve and other parts. The intercooler is used to cool the high-temperature air discharged by the air compressor to reduce the temperature of the air entering the stack to the appropriate temperature required by the stack. The humidifier uses the high humidity of the air leaving the stack to humidify the dry air before the stack enters the stack. Since the humidifier is a passive humidification component, the degree of humidification cannot be controlled. Generally, a bypass valve and a stop valve are configured to control the flow of dry air entering the humidifier, so that part of the dry air flows through the humidifier for humidification, and the other part of the dry air bypasses the humidifier without humidification and then merges with the humidified air. By adjusting the opening of the bypass valve and the stop valve, the flow of dry air entering the humidifier and not entering the humidifier can be adjusted to achieve the purpose of controlling the relative humidity of the air entering the stack.
[0003] From the current technical route, the centralized arrangement of valves such as intercoolers, humidifiers, and bypasses is the main technical development direction, but not only can there be too many and complex pipeline designs, but the layout space is limited and verification is also difficult to avoid many potential leakage points. For example, when the distance between two intercoolers and humidifiers is very close and the relative position is very extreme, it is often difficult to take into account both the design functionality and production convenience of the pipeline at the same time, because the intersection of each pipe mouth causes interference between the manufacturing molds, so other alternatives must be found. In order to solve this technical problem, this application hereby proposes an integrated joint for a fuel cell intercooler and humidifier. Summary of the invention
