Automated closure for hermetically sealing an immersion cooling tank during a hot swap of equipment therein

A retractable cover sheet system comprising:

• a motorized assembly;
• a linear guide assembly;
• a condenser;
• at least one retractable cover sheet assembly further comprising a cover sheet and a cylinder assembly;
• the computer controlled motorized assembly operates the linear guide assembly to displace both the condenser and the at least one retractable cover sheet;
• the cover sheet is spooled within the cylinder assembly when displacing the at least one cover sheet to form a sized opening to access an object stored in an immersion cooling tank, and
• wherein the condenser coincides with the sized opening just beneath the cover sheet around the perimeter of the sized opening.

A retractable cover sheet system comprising:

• a containment structure in cooperation with a retractable cover sheet assembly;
• the retractable cover sheet assembly forms a first sized opening above a first object stored within a tank;
• the containment structure is positioned above and surrounds the first sized opening,
• wherein the walls of the containment structure accumulate dielectric vapor, and
• a condenser configured to coincide with the sides of the sized opening without extending into the sized opening, as the retractable cover sheet is extended and retracted, the condenser condenses the accumulated dielectric vapor into a dielectric liquid.
