Project Abstract
Different concepts are available for the cooling of temperature-sensitive components. In comparison to air or liquid cooling, direct-evaporation of a refrigerant has the following advantages:
- Highly efficient heat transfer during boiling of the refrigerant,
- thus more compact designs of heat exchangers,
- large cooling capacities,
- uniform temperature distribution by constant evaporation temperature.
In the case of the parallel connection of evaporator tubes, however, a maldistribution of the refrigerant can occur. The target of the project is the examination of this mechanism for different refrigerants.
