Abstract

An arrangement of a thermoelectric heat pump in at least one first fluid circuit, one second fluid circuit and one third fluid circuit is provided for a motor vehicle. The arrangement has a first heat exchanger provided for exchange of heat between a fluid of the first fluid circuit and a fluid of a third fluid circuit, and a second heat exchanger is provided for the exchange of heat between a fluid of the second fluid circuit and the fluid of the third fluid circuit. In each case one thermoelectric element is arranged between the heat exchange regions of the first heat exchanger and between the heat exchange regions of the second heat exchanger.

First claim

What is claimed is:

1. A thermoelectric heat pump arrangement in at least one first fluid circuit, one second fluid circuit and one third fluid circuit for a motor vehicle, comprising a first heat exchanger disposed for exchanging heat between a fluid of the first fluid circuit and a fluid of a third fluid circuit, a second heat exchanger disposed for exchanging heat between a fluid of the second fluid circuit and the fluid of the third fluid circuit, and thermoelectric elements arranged respectively between heat exchange regions of the first heat exchanger and between heat exchange regions of the second heat exchanger.

2. The arrangement of claim 1 , further comprising a fourth fluid circuit and a third heat exchanger disposed for exchanging heat between a fluid of the fourth fluid circuit and the fluid of the third fluid circuit.

3. The arrangement of claim 2 , further comprising a thermoelectric element arranged between heat exchange regions of the third heat exchanger.

4. The arrangement of claim 1 , further comprising a first valve communicating with the first heat exchanger for controlling the fluid flow of the fluid of the third circuit through the first heat exchanger, a second valve communicating with the second heat exchanger for controlling the fluid flow of the fluid of the third circuit through the second heat exchanger, and a third valve communicating with the third heat exchanger for controlling the fluid flow of the fluid of the third circuit through the at least one third heat exchanger.

5. The arrangement of claim 2 , further comprising a first valve communicating with the first heat exchanger for controlling the fluid flow of the fluid of the first circuit through the first heat exchanger, a second valve communicating with the second heat exchanger for controlling the fluid flow of the fluid of the second circuit through the second heat exchanger, and a third valve communicating with the third heat exchanger for controlling the fluid flow of the fluid of the fourth circuit through the third heat exchanger.

6. The arrangement of claim 5 , wherein at least one of the valves is arranged upstream and/or downstream of the heat exchanger in terms of fluid flow.

7. The arrangement of claim 5 , wherein at least one of the valves is a throttle valve.

8. The arrangement of claim 1 , wherein the thermoelectric element is a Peltier element.

9. The arrangement of claim 1 , wherein the thermoelectric element is electrically and/or electronically actuable.

10. The arrangement of claim 1 , wherein the heat exchangers are arranged in a housing.

11. The arrangement of claim 1 , wherein the heat exchangers are arranged in parallel or in series with respect one another in terms of the fluid flow of the third circuit.
