In-a vehicle energy management system engine belt or engine direct driven components are replaced with electrical motors. A main fan unit is replaced with smaller single function electrical components. The larger multipurpose heat exchangers such as the vehicle radiator are replaced with smaller single function heat exchangers associated with the smaller electric fans. The energy management system may involve a main vehicle engine crankshaft mounted generator. This generator creates high voltage DC electricity. In one embodiment, the converter is a closed loop converter that makes the conversion of DC to AC alternatively turning on and off at a varying frequency in order to produce a time averaged AC output.

A cooling structure includes a plurality of plate-shaped heat generating members such as battery parts, DC voltage converters and electrical member (e.g., relay). In the cooling structure, the heat generating members are arranged in a plate-thickness direction to have predetermined spaces for forming fluid passages each of which is provided between adjacent heat generating members, and the fluid passages are provided to pass a fluid for cooling the heat generating members. Accordingly, all the heat generating members can be effectively cooled while the cooling structure can be made compact.

The invention relates to a system which is used to cool at least one piece of motor vehicle equipment to a low temperature, comprising a heat transfer fluid circulation loop. According to the invention, a low-temperature heat exchanger (60) and at least one equipment exchanger (102) are mounted to the aforementioned circulation loop. The heat exchange surface of the equipment exchanger (102) is divided into at least first and second heat exchange sections (104, 106). A first flow (Q 1 ) of heat-transfer fluid passes through the first heat exchange section (104), while a second smaller flow (Q2) passes through the second section. The invention is suitable for motor vehicle heat exchangers.
