PRESSURE CONTROLLED MULTI-MODE MULTI-WAY VALVE FOR WATER SPRAY DISTRIBUTION ON RADIATOR FOR FUEL CELL ELECTRIC VEHICLE

Abstract

A thermal management system for a vehicle having a fuel cell stack is provided. The thermal management system includes a radiator, a storage reservoir, a pump, a valve assembly and a controller. The valve assembly selectively delivers the liquid product water to a drain and to a first spray manifold that sprays the liquid product water at the radiator. The valve assembly includes: a first valve assembly disposed in a drain valve chamber of the valve housing and having a first biasing member that biases a first pin against a first inlet, the first valve assembly selectively communicating the liquid product water to the drain; and a second valve assembly disposed in a second valve chamber of the valve housing and having a second biasing member that biases a second pin against a second inlet, the second valve assembly selectively communicating the liquid product water to the first spray manifold.
