Direct coolant contact vapor condensing

A coolant-cooled electronic system comprising:

• an electronic system cooled, at least in part, by a working fluid boiling within an electronic system housing and
• a cooling apparatus comprising a vapor condenser in fluid communication with the electronic system housing to facilitate transfer of the working fluid therebetween, the vapor condenser comprising;
• a condenser housing comprising a condensing chamber accommodating the working fluid and a coolant, the working fluid and the coolant being in direct contact within the condensing chamber and being immiscible fluids, and the condensing chamber comprising a working fluid vapor layer and a working fluid liquid layer;
• a working fluid vapor inlet and a working fluid liquid outlet, the working fluid vapor inlet facilitating flow of working fluid vapor into the condensing chamber from the electronic system housing, and the working fluid liquid outlet facilitating egress of working fluid liquid from the condensing chamber for return to the electronic system housing;
• a coolant inlet structure and a coolant outlet structure, the coolant inlet structure facilitating ingress of the coolant into a working fluid layer region of the condensing chamber in direct contact with the working fluid vapor to facilitate condensing of the working fluid vapor into the working fluid liquid and thereby transfer of heat from the working fluid vapor to the coolant, and the coolant outlet structure facilitating subsequent egress of coolant from the condensing chamber of the condenser housing;
• and
• wherein the coolant outlet structure is disposed. at least partially, within the condensing chamber in a coolant layer within the condensing chamber, between the working fluid vapor layer and the working fluid liquid layer.

A method comprising:

• providing a vapor condenser, wherein providing the vapor condenser comprises:
• providing a condenser housing comprising a condensing chamber accommodating a working fluid and a coolant, the working fluid and the coolant being in direct contact within the condensing chamber and being immiscible fluids, and the condensing chamber comprising a working fluid vapor layer and a working fluid liquid layer;
• providing a working fluid vapor inlet and a working fluid liquid outlet, the working fluid vapor inlet facilitating flow of working fluid vapor into the condensing, chamber, and the working fluid liquid outlet facilitating egress of working fluid liquid from the condensing chamber;
• providing a coolant inlet structure and a coolant outlet structure, the coolant inlet structure facilitating ingress of coolant into the working fluid vapor layer of the condensing chamber in direct contact with the working fluid vapor to facilitate condensing of the working fluid vapor into the working fluid liquid and thereby transfer of heat from the working fluid vapor to the coolant, and the coolant outlet structure facilitating subsequent egress of the coolant from the condensing chamber of the condenser housing;
• and
• wherein providing the coolant outlet structure comprising disposing the coolant outlet structure, at least partially, within the condensing chamber in a coolant layer within the condensing chamber between the working fluid vapor layer and the working fluid liquid layer, and providing a coolant-working fluid separation baffle disposed, at least partially, over the coolant outlet structure, the coolant-working fluid separation baffle comprising a plurality of fluid pass through openings located in the condensing chamber at a height below the coolant outlet structure and within the working fluid liquid layer of the condensing chamber.
