Abstract: A cooling apparatus for removing heat having a low profile unitary member. The low profile unitary member has an evaporator portion and a condenser portion. The evaporator portion is thermally exposed to a heat generating component. The condenser portion is disposed at an elevated angle with respect to the evaporator portion. A plurality of microtubes are disposed within the first low profile extrusion. The plurality of microtubes have a heat transfer fluid contained therein. A second plurality of low profile extrusion members are mounted as fins on the evaporator section of the low profile unitary member. Heat is transferred from the heat generating component to the heat transfer fluid contained with the microtubes located within the evaporator portion. The heat transfer fluid to which the heat was transferred migrates to the condenser portion of the low profile unitary member by way of the microtubes. The heat transfer fluid is cooled in the condenser portion of the low profile unitary member.

Abstract: A cooling apparatus using “low profile extrusions” is disclosed. The cooling apparatus of the present invention may be incorporated into a closed loop liquid cooling system which is particularly well suited to heat removal from electronic components in applications where space is limited. A cooling system in accordance with the present invention is illustrated for use in a typical wireless telecommunication base station for removing heat from power amplifiers and other electronic components. Cooling is carried out by drawing heat away from the electronic components and into at least one low profile extrusion attached directly to the heat generating components or a heat sink, and transferring the removed heat to a cooling fluid circulating through a plurality of micro tubes or channels within each low profile extrusion.

Abstract: An air conditioning apparatus and method for cooling enclosures containing electronic equipment. More particularly, one aspect of the present invention comprises a low cost passive heat removal system that utilizes a plurality of flat tubing or low profile extrusions. The flat tubing or low profile extrusions are arranged in parallel to create an air-to-air passive heat exchanger which may be incorporated into an air conditioning apparatus constructed in accordance with the present invention. The flat tubes or low profile extrusions offer a greater surface area and more efficient cooling than conventional folded fin designs having the same overall dimensions or volume. Moreover, the flat tubes or low profile extrusions may be manufactured with dimples, fins, or other surface enhancements with little additional labor or manufacturing steps. The air-to-air passive heat exchanger may be arranged in various configurations including cross flow, counterflow or concurrent flow.

Abstract: A system for conditioning the air within an enclosure which houses heat producing equipment. The system includes a passive heat removal system, for precooling the air, and a thermoelectric temperature control system used in conjunction with the passive heat removal system to achieve the necessary temperature control. A power control system includes a programmable control means which receives signals, from a temperature sensor, which are indicative of the temperature of the air in the enclosure. Based upon these signals, the power control system controls the activation of thermoelectric devices in the thermoelectric temperature control system and controls the activation of fans to remove a desired amount of heat from the air in the enclosure and discharge the unwanted heat to the outside air. A switching device operates to apply battery power to the power control system if the electrical power source for the thermoelectric temperature control system fails.
