Abstract

A flexible heat exchanger is suitable for heating or cooling living subjects or objects. The heat exchanger has a volume having at least one inlet for receiving a heat exchange fluid and at least one outlet. A flexible heat exchange plate that is essentially impermeable to the heat exchange fluid is penetrated by substantially rigid thermally-conductive members. The members provide paths of high thermal conductivity through the plate. The heat exchange fluid may be water.
