Abstract
A device for cooling the heat engine, electrical components, and an electrical energy storage device including: a first circuit, a second circuit, and a third circuit for cooling each of the heat engine, the electrical components, and the electrical energy storage device, respectively; a heat exchange device separated into three members, including a high temperature member connected to the first circuit, a low temperature member connected to the second circuit, and a very low temperature member connected to the third circuit; an upstream valve connected between the first and the third circuit located upstream of the high temperature member of the heat exchanger in the first circuit; and, a downstream valve connected between the first circuit and the third circuit located downstream of the high temperature member of the heat exchanger in the first circuit, where the downstream valve is a thermostatic valve which is actuated as a function of the temperature of the heat transfer fluid in the first circuit and where the upstream valve is actuated as a function of flow of the heat transfer fluid in the first circuit.
