1. A bellows assembly for a two-phase immersion cooling system, the bellows assembly comprising:
a container comprising a polymer and enclosing a volume, the container having a first surface spanning a first surface area that encloses the volume, wherein at least a portion of the container is reversibly deformable to increase and decrease an amount of the volume enclosed by the container;
a first wall comprising the polymer and having a second surface spanning a second surface area;
a second wall having a third surface spanning a third surface area, the second wall separated from the first wall by at least a portion of the volume and oriented approximately parallel to the first wall when the volume is not under pressure or vacuum, wherein the second surface area and the third surface area comprise a majority of the first surface area;
a third wall extending between and connected to the first wall and the second wall;
at least one port in the third wall to admit gas into the volume and expel the gas from the volume; and
at least one hardware element attached to at least one of the first wall, the second wall, and the third wall to mount the container in an orientation such that at least one of the first wall and the second wall deforms or deform outward from a center of the container without external hinderance when the volume is under pressure and deforms or deform inward without external hinderance when the volume is under vacuum.
