Abstract

An auxiliary cooling device to be used in another cooling device, which auxiliary cooling device includes a thermoelectric element, such as a Peltier element, provided with a heat source and a heat sink connected in a circuit. The heat sink is used for directly or indirectly cooling an item, for example a bottle of fluid. The heat source, which is thermally isolated with respect to the heat sink, is in close thermal contact with a heat exchange fluid in a container. The heat exchange fluid is used as a thermal buffer for the waste heat generated by the cooling process.
