Abstract

The application relates to thermoelectric temperature control units, for example for controlling the temperature of an energy storage device in a motor vehicle. An exemplary embodiment comprises a Peltier element, having a first and a second surface, wherein the second surface is substantially adjacent or opposite to the first. The first surface is connected in a thermally conductive manner to a first and/or second flow duct, through which a fluid can flow. The second surface is connected in a thermally conductive manner to a heat-producing element, wherein the first flow duct is in fluid communication at one of the ends thereof with a first header, and the second flow duct is in fluid communication at one of the ends thereof with a second header, and the first flow duct and the second flow duct are in fluid communication at the respective second ends thereof with a common reversing header.
