Abstract

A motor vehicle heat transfer system includes a closed circuit for an operating medium, said closed circuit comprising an evaporator and a condenser arranged in the motor vehicle above the evaporator, wherein the operating medium evaporates in the evaporator and flows to the condenser and wherein liquid operating medium, which has condensed in the condenser, is conducted back into the evaporator via a return line based on gravity.

Claims

1. A motor vehicle heat transfer system, comprising a closed circuit for an operating medium, said closed circuit comprising an evaporator and a condenser arranged in the motor vehicle above the evaporator, wherein the operating medium evaporates in the evaporator and flows to the condenser and wherein liquid operating medium, which has condensed in the condenser, is conducted back into the evaporator via a return line based on gravity.

2. The motor vehicle heat transfer system of claim 1, further comprising a vapor collecting chamber assigned to the evaporator.

3. The motor vehicle heat transfer system of claim 1, wherein the evaporator comprises at least one evaporator module, said at least one evaporator module comprising a housing and a heat exchanger structure arranged in the housing.

4. The motor vehicle heat transfer system of claim 3, wherein the heat exchanger structure is configured porous.

5. The motor vehicle heat transfer system of claim 1, further comprising a compensation container for the operating medium arranged upstream of the evaporator.

6. The motor vehicle heat transfer system of claim 1, wherein the evaporator has a passage for the exhaust gas stream.
