Abstract

A thermoelectric arrangement for use in a cooling system (4, 6) of a motor vehicle has a thermocouple (8) with a first, heat-outputting thermal element (10), a second, heat-absorbing thermal element (12) and a conductor element (14) through which current flows. At least two cooling circuits (16, 18, 20) are provided. The first thermal element (10) is arranged in at least one cooling circuit (16, 18, 20), and the second thermal element (12) is arranged in at least one heating circuit (48). The first thermal element (10) is arranged in a first connecting line (22) that is connected fluidically to the respective cooling circuits (16, 18, 20) via valve arrangements (24, 26; 28, 30; 32, 34) on the input and output sides of the first thermal element (10). A cooling system having such a thermoelectric arrangement also is described.
