Two-phase, water-based immersion-cooling apparatus with passive deionization

A method of fabricating a cooled electronic module comprising:

• securing a housing about an electronic component to be cooled, the housing at least partially surrounding and forming a compartment about the electronic component to be cooled;
• disposing a fluid within the compartment, wherein the electronic component to be cooled is at least partially immersed within the fluid, and wherein the fluid comprises water;
• providing a deionizing structure within the compartment, the deionizing structure comprising deionizing material, the deionizing material ensuring deionization of the fluid within the compartment, wherein the deionizing structure is configured with vapor passages to accommodate boiling of the fluid within the compartment;
• and
• providing a vapor-condenser disposed in an upper portion of the compartment, and facilitating cooling of fluid vapor rising to the upper portion of the compartment, and wherein the method further comprises providing one of a liquid-cooled cold plate or an air-cooled heat sink coupled to the housing and cooling the vapor-condenser disposed in the upper portion of the compartment.
