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.
