  • Publication number: 20030094266
    Abstract: A cabinet has an inner roof portion and an outer roof portion above the inner roof portion. A solar shield is above the outer roof portion. A heat exchanger has a first portion that absorbs heat. The first portion of the heat exchanger is located between the inner roof portion and the outer roof portion. The heat exchanger has a second portion that rejects heat. The second portion of the heat exchanger is located between the outer roof portion and the solar shield. The heat exchanger has a heat pipe for transferring heat between the first passage and the second passage. The heat pipe includes an evaporator that absorbs heat from the heated air and a condenser that rejects heat to the cooled air.

  • Publication number: 20030030981
    Abstract: A method and apparatus for cooling heat-producing equipment, the method comprising the steps of directing heat from the heat producing equipment to a cooling loop and, circulating liquid through said cooling loop from a liquid reservoir to a radiator structure. In a first exemplary embodiment, the apparatus comprises a liquid reservoir, a pump, a radiator and a plurality of interface members. In a second exemplary embodiment, the apparatus comprises a liquid reservoir, a pump, a radiator and an air-to-liquid heat exchanger.

  • Patent number: 6131650
    Abstract: The apparatus is an easily assembled, fluid cooled, single phase heat sink. The heat sink is constructed of only four simple parts, a pan shaped casing, a simple thermally conductive porous pad, a manifold block with channels, and a lid. The lid includes input and output fluid holes which are interconnected to sets of alternating channels in the manifold block, so that adjacent channels are isolated from each other and are connected to only either the input or the output holes. Thus, the only access between the adjacent input and output channels is through the porous pad which is sandwiched between the manifold block and the bottom of the casing. Fluid flow through the porous pad thereby cools the entire bottom of the casing which is held in heat transfer relationship with a heat source.
