Abstract

The invention relates to a heat exchanger unit having an evaporator device configured for evaporating a heat exchanger operating fluid, and a condenser device for condensing the heat exchanger operating fluid, wherein the evaporator device and the condenser device are fluidically connected to each other in a frontal configuration. The invention further relates to a thermotechnical system having a plurality of heat exchanger units.

First claim

The invention claimed is:

1. A thermotechnical system, comprising:
a plurality of heat exchanger units, wherein:
the plurality of heat exchanger units is in each case formed with an evaporator device configured for evaporating a heat exchanger operating fluid and a condenser device configured for condensing the heat exchanger operating fluid, wherein the evaporator device and the condenser device are in fluid communication with each other so that the heat exchanger operating fluid can flow from the evaporator device to the condenser device, wherein the evaporator device and the condenser device are arranged in a frontal configuration with respect to each other, such that a front side of the evaporator device and a front side of the condenser device oppose each other, the front side of the evaporator device being defined by a first plurality of pipes reversing direction, and the front side of the condenser being defined by a second plurality of pipes reversing direction and wherein the evaporator device and the condenser device are entirely separated from each other, and
the plurality of heat exchanger units form a thermodynamic and process-related unit such that during operation:
evaporated heat exchanger operating fluid flows from the evaporator device of a first of the plurality of heat exchanger units to the condenser device of the first of the plurality of heat exchanger units in order to condense there at least partially forming a first liquid phase of the operating fluid,
the first liquid phase of the operating fluid generated in the condenser device of the first of the plurality of heat exchanger units is then directly transferred to the evaporator device of a second of the plurality of heat exchanger units in order to evaporate there into vapor, and
subsequently, the vapor generated in the evaporator device of the second of the plurality of heat exchanger units flows to the condenser device of the second of the plurality of heat exchanger units where a condensation takes place again and a second liquid phase of the operating fluid generated in this manner is fed again to the evaporator device of the first of the plurality of heat exchanger units;
wherein the frontal configuration and a spacing between the evaporator device and the condenser device of the first and the second plurality of heat exchanging units results in a wave formation of vapor that flows between the evaporator device and the condenser device during operation of the thermotechnical system;
wherein the spacing between the front side of the evaporator device and the front side of the condenser device of the first and second plurality of heat exchanger units is less than a length of the first plurality of pipes in a direction perpendicular to the front side of the evaporator device.

2. The thermotechnical system according to claim 1 , wherein an evaporator front face facing toward the condenser device is arranged substantially completely overlapping with a condenser device front face facing toward the evaporator device.

3. The thermotechnical system according to claim 1 , wherein each of the plurality of heat exchanger units has a droplet separator-free design.

4. The thermotechnical system according to claim 1 , wherein each of the plurality of heat exchanger units has a vapor barrier-free and/or droplet barrier-free design.

5. The thermotechnical system according to claim 1 , wherein the plurality of heat exchanger units are assembled in a modular structure.

6. The thermotechnical system, according to claim 1 , wherein the plurality of heat exchanger units are assembled corresponding to a modular structure.

7. The thermotechnical system according to claim 1 , wherein a condenser front face facing toward the evaporator device is arranged substantially completely overlapping with an evaporator device front face facing toward the condenser device.
