TEMPERATURE CONTROL UNIT FOR A GASEOUS OR LIQUID MEDIUM

For a temperature control unit for a gaseous or liquid medium with highly dynamic temperature regulation of the medium, the temperature control unit (1) is designed with a base body (2) and a heat sink (5), between which a number of thermoelectric modules (7) are arranged, and with a media line (6) in the base body (2), and it is provided that the mass ratio of the thermal storage mass of the heat sink (5) to the thermal storage mass of the base body (2) and the media line (6) arranged therein is in the range of 0.5 to 1, advantageously in the range of 0.7 to 0.8.
