IMPROVEMENTS TO FLOW ENHANCEMENT STRUCTURE FOR IMMERSION COOLED ELECTRONIC SYSTEMS

An apparatus is described that includes an immersion bath chamber and a cover that is to seal the immersion bath chamber. An apparatus is described that includes an immersion bath chamber and an installable/removable transfer member. The installable/removable transfer member has fluidic connectors designed to couple to respective warmed fluid flow output ports of pluggable units to be cooled in the immersion bath chamber and having respective backplane interface designs. An apparatus is described that includes an immersion bath chamber and an overflow chamber. The overflow chamber is to receive an overflow of liquid coolant from the immersion bath chamber, wherein a first exit flow channel from the overflow chamber is coupled to a second exit fluid flow channel from the immersion bath chamber through a valve, wherein, an opening of the valve is controllable to vary a gravitational fluid flow within the immersion bath chamber.
