Abstract

A motor vehicle heat exchanger system with a closed circuit for an operating medium includes an evaporator for evaporating the operating medium and a condenser for condensing the vaporous operating medium AM is provided. A reservoir for the liquid operating medium is integrated between the condense and the evaporator. Liquid operating medium is conducted from the reservoir via a feed line into the evaporator. In addition the reservoir and the evaporator are connected with each other via a compensation line. Vapor which may form during operation of the motor vehicle heat exchanger system on the liquid side of the evaporator can escape through the compensation line thereby achieving a pressure compensation.

First claim

What is claimed is:

1 . A motor vehicle heat exchanger system with a closed circuit for circulating an operating medium, said heat exchanger system comprising:
an evaporator for evaporating liquid operating medium to vaporous operating medium; a condenser for condensing the vaporous operating medium; and a reservoir for receiving the liquid operating medium, said reservoir being arranged between the condenser and the evaporator, wherein the reservoir and the evaporator are connected with each other via a feed line for conduction of liquid operating medium, and wherein the reservoir and the evaporator are further connected with each other via a compensation line.

2 . The motor vehicle heat exchanger system of claim 1 , wherein the evaporator comprises at least one evaporator cassette, wherein a capillary structure is arranged in the evaporator cassette and the evaporator cassette has a liquid side and a vapor side and a vapor collector.

3 . The motor vehicle heat exchanger system of claim 2 , wherein the compensation line is connected with the liquid side of the at least one evaporator cassette.

4 . The motor vehicle heat exchanger system of claim 1 , wherein the compensation line is connected to the evaporator via a compensation connection and the feed line is connected with the evaporator via a feed connection, said compensation connection being positioned above the feed connection.

5 . The motor vehicle heat exchanger system of claim 2 , wherein the capillary structure is formed by a porous plate body made of a sintered material.

6 . The motor vehicle heat exchanger system of claim 1 , wherein the capillary structure has vapor grooves and/or vapor channels on the vapor side.

7 . The motor vehicle heat exchanger system of claim 1 , wherein the evaporator has at least two evaporator cassettes, and wherein a channel is formed between the at least two evaporator cassettes.

8 . The motor vehicle heat exchanger system of claim 7 , wherein the channel is an exhaust gas channel.

9 . The motor vehicle heat exchanger system of claim 7 , further comprising heat transfer elements provided in the channel.

10 . The motor vehicle heat exchanger system of claim 2 , wherein on the vapor side of an evaporator cassette vapor grooves and/or vapor channels are provided in the bottom of the housing of the evaporator cassette.
