WAHLER Hydrogen Energy - Electronic Multi way Valve
At present, the development of hydrogen fuel cell vehicles is booming, but most hydrogen fuel cell stacks use the cooling system of traditional fuel vehicles, which adjusts the switching of the cooling cycle through a wax thermostat. This causes some hot water to flow back to the water tank during the small cycle, while cold water enters the small cycle through the replenishment port at the front end of the water pump, resulting in a long cold start time. Moreover, during the switching of large and small cycles, The small loop is completely closed, and all water flows through the large loop. The cold water in the radiator enters and causes the water temperature passing through the stack to drop instantly, causing a cold shock to the stack and causing significant water temperature fluctuations.
