Abstract: A fluid heat exchanger unit cools an electronic device with a cooling fluid supplied to an upper portion of a cooling housing. A refrigerant is disposed in a lower portion of the cooling housing for liquid-to-vapor transformation. A partition divides the upper portion of the cooling housing from the lower portion. A heat rejecter is disposed on and above the upper wall of the cooling housing with a first header extending from and in fluid communication with the liquid coolant outlet. A second header extends upwardly from a rejecter outlet. A plurality of first tubes extend between and in fluid communication with the first header and the second header with a plurality of first air fins disposed between the upper wall and the first tubes. A single unit defines both the cooling housing and the air cooled heat rejecter to thereby allow the manufacture of the unit in a single process with the attendant reduction in shipping, handling and installation.

Abstract: A heat sink clip for securing a heat sink to a heat generating electronic component includes a spring member including an elongated main body. A connecting portion is formed at one end of the main body and a first locking leg extends from the other end thereof. A second locking leg is coupled to the connecting portion of the spring member.

When the actuating member is rotated from a first orientation to a second orientation, the assisting member horizontally moves a distance thereby moving the actuating member to a raised level. The actuating member has teeth engaging with teeth formed on an inclined face of the wedged main body.

Abstract: A heat pipe includes an outer pipe (10), an inner pipe (20), and a hermetic cap (30). The outer pipe has an evaporating end (12) and a condensing end (14). The evaporating end is integrally sealed and receives working fluid. The inner pipe includes an open top and an open bottom. A very narrow gap (40) is defined between the inner pipe and the outer pipe. A plurality of granules is put into the gap to form a porous wicking structure. When the evaporating end is heated by an external heat source, the working fluid is vaporized and flows up along the inner pipe to the condensing end. The working fluid condenses at the condensing end, and flows back down to the evaporating end through the gap. Because the gap is very narrow, surface tension of the working fluid and capillary action of the outer and inner pipes is enhanced.

Abstract: The present invention relates to an improved air conditioning filter and cooling/heating coil that can easily be applied to new and existing air handling systems. The slant design of these components allows a more efficient heat transfer and particle entrapment than their conventional counterparts. By residing at an angle in their air handling enclosures, and by virtue of their oblique prismatic construction, more filter media can be used and more heat transfer surface area can be incorporated without offering any substantial additional impediments to the flow of air. At angles of 45 degrees air friction of the coil and filter are reduced by 40 to 55 percent.
