1. A temperature control device for a battery storage module comprising:
a temperature control circuit configured to control a temperature of a plurality of battery cells in the battery storage module;
wherein the temperature control circuit carries a temperature control medium and includes a plurality of channels that are in thermal contact with the battery cells, the temperature control medium being in thermal contact with a temperature control source;
characterized in that
a pump for conveying the temperature control medium includes:
a spindle housing having an inlet opening and an outlet opening; and
at least one screw spindle rotatably accommodated inside the spindle housing and coupled to an electric motor;
wherein the electric motor is formed as a dry-running motor and is arranged so as to be separated from the spindle housing,
wherein an accommodation housing includes an opened cavity and a feeder line as well as a return line of the temperature control circuit, wherein the feeder line and the return line open into the opened cavity,
wherein the spindle housing is configured to be inserted into the opened cavity from an axial end of the spindle housing up to a housing flange, wherein the temperature control circuit is configured to connect to the inlet opening and the outlet opening of the spindle housing,
wherein the pump has a pump head that is formed by the spindle housing and the at least one screw spindle, wherein the pump head is configured to be inserted into the opened cavity,
wherein the feeder line opens into a peripheral surface of the opened cavity of the accommodation housing, wherein the return line opens into an end-face base surface of the opened cavity of the accommodation housing, and wherein a sealing element is located between the end-face base surface and the axial end of the spindle housing and surrounds the return line and the inlet opening.
