Abstract
A heat exchanger such as a cold plate or ICE plate has an integrated electric heating element provided on an external heater support surface of the heat exchanger. The external heater support surface is directly opposite to an internal surface of the heat exchanger which at least partly defines one or both of the inlet manifold and the outlet manifold. A thermal management system for a vehicle having a plurality of rechargeable battery units includes a circulation loop for circulating a first volume of the heat transfer fluid, and a plurality of battery heat exchangers, including a first heat exchanger with an integrated electric heating element. A sub-loop of the circulation loop includes the internal fluid flow passage of the first heat exchanger, and is adapted for a second, smaller volume of the heat transfer fluid.
