  • Publication number: 20140209288
    Abstract: A method and an apparatus are provided for cooling a heat source using a refrigerant flow in a heat exchanger. According to some embodiments, a flow property of the refrigerant as it flows through a heat exchanger is measured and based on the measurement a flow distribution rate for the flow of the refrigerant in the heat exchanger is determined. A valve is operated for adjusting the flow rate of the refrigerant in the heat exchanger according to the determined flow distribution rate.

  • Patent number: 8542489
    Abstract: An apparatus comprising a rack having a row of shelves, each shelf supporting an electronics circuit board, each one of the circuit boards being manually removable from the shelve supporting the one of the circuit boards and having a local heat source thereon. The apparatus also comprises a cooler attached to the rack and being able to circulate a cooling fluid around a channel forming a closed loop. The apparatus further comprises a plurality of heat conduits, each heat conduit being located over a corresponding one of the circuit boards and forming a path to transport heat from the local heat source of the corresponding one of the circuit boards to the cooler. Each heat conduit is configured to be manually detachable from the cooler or the circuit board, without breaking a circulation pathway of the fluid through the cooler.

  • Publication number: 20120279683
    Abstract: An apparatus comprising a rack having one or more shelves, a plurality of electronics circuit boards and heat conduits and a cooler. Each board is held by one of the one or more shelves, some of the boards having a localized heat source thereon. Each heat conduit forms a heat conducting path over and adjacent to a particular one of the boards from a region adjacent to the heat source thereon to a connection zone, the zone being remote from the heat source. The cooler is located on a side of the rack and coupled to the zones such that heat is transferable from the paths to the cooler. The cooler is configured to flow a cooling fluid therein to cool localized thermal interfaces at the cooler, each interface being adjacent to and at a corresponding one of the zones.

  • Publication number: 20070012938
    Abstract: A light-emitting-diode packaging structure having thermoelectric device, which is applied to the LED unit packaged using the flip chip technology. This is realized by directly building the thermoelectric elements into the solder bump layer of the light-emitting-diode packaging structure to replace a part of the solder bumps, as such raising the heat dissipation efficiency of the light emitting diode unit, enhancing the stability and reliability of light emission of the LED unit, and reducing the difficulties and complexity of the integration of the LED package.
