A flow boiling chamber with interchangeable plug-in heater module was designed that allows for the investigation of different finned cooler structures and surface topologies and chemistry respectively to enhance small bubble formation and release. In this experimental investigation a finned and a pin finned cooler structure using mm-size dimensions were used. It could be shown that the pin finned and finned cooler structure show for low flow rates at low pressure drop the same performance. Furthermore, it could be observed that the heat transfer coefficient could be increased for both cooler structure in the two-phase regime as opposed to single-phase convective liquid cooling.

To have the possibility for investigations of new electronic packages that supports cooling solutions by two-phase flow boiling, a multipurpose closed two-phase flow boiling cooling test stand for rapid experimental characterization and parameter variation is designed. The designed test vehicle holds interchangeable, plug-in heating module that offers the possibility to investigate different cooler structures and surface topologies/chemistry to improve the formation and release of small bubbles. In order to have a proof of concept for the test stand and to show its reproducible to those given in the literature, initially, the investigation is limited to a plain-and dimpled-surface and a pin fin and finned cooler structure in the mm range.
