Abstract
Abstract A cryogenic vessel for cooling electronic components, wherein the cryogenic vessel includes a pair of vessel portions, each vessel portion having an outer wall and an interior immersion chamber. A membrane member is located between the vessel portions for separating the mentioned immersion chambers. The membrane member includes openings for providing fluid transfer between the immersion chambers of the vessel portions and a portion extending from between the vessel portions to a point exterior of the vessel portions. Sealing members are located between the membrane member and each of the vessel portions for providing a fluid tight seal of the immersion chambers. An electronic component mounting socket is located on a portion of the membrane member within the immersion chambers for mounting an electronic component to be cooled. A supply conduit through the outer wall of one of the vessel portions introduces cryogenic fluid into the immersion chambers.
