Air or liquid cooled computer module cold plate

A cold plate, comprising,

• a mounting plate for carrying thereon a printed circuit board assembly,
• a cover generally parallel to and spaced from said mounting plate, and
• a cooling chamber defined by the space between said cover and said mounting plate, said cooling chamber comprising:
• a liquid cooled section disposed within said cooling chamber and including a coolant inlet, a coolant outlet, at least one internal fin assembly and at least one coolant flow channel for directing a liquid coolant from said coolant inlet through said liquid cooled section to said coolant outlet in order to carry away heat generated by said printed circuit board assembly, and
• an air cooled section disposed within said cooling chamber separate from said liquid cooled section and including an air inlet, an air outlet, and at least one air flow channel for directing air from said air inlet through said air cooled section to said air outlet for carrying away heat generated by said printed circuit board assembly,
• wherein said liquid cooled section and said air cooled section of said cooling chamber are separated by a divider plate disposed generally parallel to and between said mounting plate and said cover, wherein said divider plate has an air cooling surface on one side disposed adjacent said air cooled section and a liquid cooling side on the other side of said divider plate disposed adjacent said liquid cooled section, wherein a portion of said liquid cooling side of said divider plate comprises a recessed surface for receiving therein said at least one internal fin assembly.

A cold plate for a computer clock module comprising,

• a mounting plate for carrying thereon a clock printed circuit board assembly,
• a cover generally parallel to and spaced from said mounting plate,
• a cooling chamber defined by the space between said cover and said mounting plate, said cooling chamber comprising:
• a divider plate having an air cooling surface on one side and a liquid cooling side on the other side, said divider plate being disposed generally parallel to and between said mounting plate and said cover,
• a liquid cooled section within said cooling chamber between said liquid cooling side of said divider plate and said mounting plate, and including a coolant inlet, a coolant outlet, and a plurality of coolant flow channels for directing a liquid coolant from said coolant inlet through said liquid cooled section to said coolant outlet for carrying away heat generated by said clock printed circuit board assembly, and
• an air cooled section within said cooling chamber separate from said liquid cooled section between said air cooling side of said divider plate and said cover, and including an air inlet, an air outlet, and a plurality of air flow channels for directing air from said air inlet through said air cooled section to said air outlet for carrying away heat generated by said clock printed circuit board assembly.
