Abstract
A device and method for cryogenic cooling of electronic components. A mixture of a first non-condensible gas and a second condensible gas is provided within an insulative housing. The non-condensible gas mixture has a partial pressure equal to the desired saturation pressure of the condensible gas. The insulative housing also includes an immersion chamber for housing electronic components. The immersion chamber preferably comprises two retainer parts and provides an module retainer top and a lower coldplate retainer bottom. The module retainer top allows gas to pass through the module retainer portion freely. The condensible gas is then turned into liquid form by a provided condensing means. The condensed liquid thus forms and collects inside the immersion chamber against the coldplate retainer bottom to cool the electronic components placed within. The non-condensible gas permits the condensed liquid to be subcooled.
