Cooling system with a porous foam heat exchanger and a positive displacement air pump

A method of manufacturing a cooling system for an information handling system in a portable chassis, the method comprising:

• positioning a vapor chamber in the chassis, the vapor chamber comprising a vapor chamber first surface and a vapor chamber second surface, wherein positioning the vapor chamber in the chassis causes contact between at least one of the vapor chamber first surface and the vapor chamber second surface with one or more components of the information handling system in the chassis;
• positioning a porous heat exchanger in sealed contact with the vapor chamber;
• and
• positioning an air pump in sealed contact with a plurality of sides, wherein the plurality of sides comprises the porous heat exchanger as one side, wherein the vapor chamber first surface, the air pump second surface and the plurality of sides form an internal air chamber, wherein
• the vapor chamber conducts heat away from the one or more components of the information handling system to the porous heat exchanger,
• the air pump draws a first airflow into the air pump inlet at a first air pressure and generates a second airflow at a second air pressure in the internal air chamber that is higher than the first air pressure, whereby the second airflow is forced through the porous heat exchanger, and
• the porous heat exchanger transfers heat from the vapor chamber to the second airflow.

A portable chassis for an information handling system comprising a plurality of components that generate heat during processing instructions, the portable chassis comprising:

• a vapor chamber comprising a vapor chamber first surface and a vapor chamber second surface, wherein at least one of the vapor chamber first surface and the vapor chamber second surface is in contact with one or more of the plurality of heat generating components in the chassis;
• a porous heat exchanger in sealed contact with the vapor chamber;
• an air pump in sealed contact with the porous heat exchanger, the air pump comprising an air pump first surface having an air pump inlet and an air pump second surface opposite the air pump first surface, the air pump second surface having an air pump outlet;
• an internal air chamber defined by the air pump second surface, the vapor chamber first surface and a plurality of sides, wherein at least one side comprises the porous heat exchanger;
• and
• a cover comprising a vent, wherein:
• the vapor chamber is configured to conduct heat away from the one or more heat generating components to the porous heat exchanger,
• the air pump is configured to draw a first airflow at a first air pressure into the air pump inlet and generate a second airflow out the air pump second surface at a second air pressure in the internal air chamber, whereby the second pressure forces the second airflow through the porous heat exchanger, and
• the porous heat exchanger is configured to transfer heat from the vapor chamber to the second airflow;
• and
• the vent is configured to allow the second airflow to exit to the ambient environment.
