Abstract
Fluid replacement structures used in immersion cooling tanks can include various enhancements to make them functional beyond simply taking up space. For example, the density of fluid replacement structures can be variable to assist with buoyancy control. As another example, fluid replacement structures can be designed to enable vaporized working fluid to be directed to a desired location. As another example, fluid replacement structures can include emergency cooling features, such as different substances that cause an endothermic reaction to occur when they are mixed together. The substances can be separated by a membrane that melts when the temperature reaches a certain point. As another example, a fluid replacement structure can provide structural support for an immersion cooling tank when negative pressure operations are performed. Fluid replacement structures can also include alignment features, lifting features, locking features, mating guides, fiducial markers, or the like.
