Abstract: A manifold for a two-phase cooling system for efficiently transferring coolant within a multi-phase cooling system. The manifold for a two-phase cooling system generally includes an extruded manifold having a supply chamber and a return chamber in thermal communication with one another to provide for efficient coolant transfer between a thermal server and a spray module.

Abstract: A two-phase liquid cooling system includes an active venting system for regulating an amount of non-condensable gas within the cooling system. Various venting structures may be used to remove gases from the cooling system, some of which are designed to remove the non-condensable gases and avoid removing the vapor-phase coolant. A control system activates the venting system to achieve a desired pressure, which may be based on measured process conditions within the cooling system.
