Immersion cooling system

An immersion cooling system comprising:

• a work tank having a work-tank gas-phase region and a work-tank liquid-phase region;
• a buffer tank having a buffer-tank gas-phase region and a buffer-tank liquid-phase region;
• and
• a communication control assembly comprising:
• a first pipeline;
• a first pump, wherein in response to that actuation of the first pump is actuated, through the first pipeline, a fluid of the work-tank liquid-phase region is transported to the buffer-tank liquid-phase region or a fluid of the buffer-tank liquid-phase region is transported to the work-tank liquid-phase region;
• a second pipeline;
• a second valve, wherein in response to that actuation of the second valve is actuated, through the second pipeline, the work-tank gas-phase region is selectively in communication with the buffer-tank gas-phase region;
• a third pipeline;
• and
• a third pump, wherein in response to actuation of the third pump, through the third pipeline, the fluid of the work-tank liquid-phase region is transported to the buffer-tank liquid-phase region or the fluid of the buffer-tank liquid-phase region is transported to the work-tank liquid-phase region.
