Heat exchanger unit and thermotechnical system

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 heat exchanger operating fluid can flow and are arranged in a frontal configuration with respect to each other, and
• the plurality of heat exchanger units form a thermodynamic and process-related unit such that during operation
• evaporated operating fluid flows from an evaporator device to the condenser device of one of the heat exchanger units in order to condense there at least partially, that liquid generated in the condenser device is then transferred to the evaporator device of a further one of the plurality of heat exchanger units in order to evaporate there into vapor, and
• subsequently, the vapor flows to the condenser device of the further heat exchanger unit where a condensation takes place again and the liquid generated in this manner is fed again to the evaporator unit.
