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.

A thermoelectric arrangement for a cooling system (4, 6) of a motor vehicle comprising: a thermocouple (8) with a first, heat-outputting thermal element (10) having a fluid inlet and a fluid outlet, a second, heat-absorbing thermal element (12) having a fluid inlet and a fluid outlet and a conduc
1. A thermoelectric arrangement for a cooling system (4, 6) of a motor vehicle comprising: a thermocouple (8) with a first, heat-outputting thermal element (10) having a fluid inlet and a fluid outlet, a second, heat-absorbing thermal element (12) having a fluid inlet and a fluid outlet and a conductor element (14) through which current flows, the second thermal element (12) being arranged in at least one heating circuit (48), a fluid inlet line (22) that is fluidically connected to the inlet of the first thermal element (10) and a fluid outlet line that is fluidically connected to the fluid outlet of the first thermal element (10), at least first and second cooling circuits (16, 18, 20), first and second upstream connecting lines (36, 40) connecting the respective first and second cooling circuits (16, 18) to the fluid inlet line (22), first and second upstream valve arrangements (24; 28; 32) in the respective first and second upstream connecting lines (36, 40), first and second downstream connecting lines (38, 40) connecting the fluid outlet line from the first thermal element (10) respectively to the first and second cooling circuits (16, 18), and first and second downstream valve arrangements (26; 30; 34) in the respective downstream connecting lines, wherein the respective upstream and downstream valve arrangements (24, 26; 28, 30; 32, 34) are configured so that, in first positions of the respective upstream and downstream valve arrangements (24, 26; 28, 30; 32, 34), the corresponding cooling circuit (16, 18, 20) is in communication with the first thermal element (10) and in second positions of the respective upstream and downstream valve arrangements (24, 26; 28, 30; 32, 34), the corresponding cooling circuit (16, 18, 20) bypasses the first thermal element (10). 2. The thermoelectric arrangement of claim 1, wherein each of the upstream valve arrangements (24, 28, 32) is a 2/2-way valve (24, 28, 32) incorporated into the respective upstream connecting line (36, 40, 44), and each of the downstream valve arrangements (26, 30, 34) is a 3/2-way valve (26, 30, 34) arranged in the downstream connecting line (38, 42, 46) at the respective cooling circuit (16, 18, 20). 3. The thermoelectric arrangement of claim 1, wherein the heating circuit (48) has a heating-type heat exchanger (56), a second connecting line (50) with an upstream section extending from the heating-type heat exchanger (56) to an input side of the second thermal element (12) and a downstream section extending from an output side of the second thermal element (12) to the heating-type heat exchanger (56), a bypass line (52) connecting the upstream section of the second connecting line (50) to the downstream section of the second connecting line (50), and a 3/2-way valve (54) incorporated into the bypass line (52) and the second connecting line (50) so that in a first operative position, the 3/2-way valve (54) directs a flow through the second thermal element (12) and in a second operative position, the 3/2-way valve (54) causes a bypass of the second thermal element (12). 4. The thermoelectric arrangement of claim 1, wherein the thermocouple (8) is a Peltier element. 5. A cooling system comprising the thermoelectric arrangement (2) of claim 1, wherein each of the cooling circuits communicates with at least one component of the vehicle that requires cooling, the first cooling circuit (16) cooling an electric drive (62) and power electronics (64), the second cooling circuit (18) cooling a high-voltage battery (74), and further comprising a third cooling circuit (20) that exchanges heat with external air. 6. The cooling system of claim 5, further comprising a valve arrangement (68, 70) connecting the first cooling circuit (16) to the third cooling circuit (20) at a position downstream of the thermoelectric arrangement (2) and upstream of the at least one component of the vehicle that requires cooling. 7. The cooling system of claim 5, wherein the heating circuit (48) has a heat exchanger (56) for heating a passenger compartment. 8.
