  • Publication number: 20120205073
    Abstract: The invention relates to a method for recovering heat from intermittently and instantaneously released blow-off steam charges. The method is carried out using a container (6) with an internal volume (2), provided with an inlet (7) and an outlet (10). The method comprises the steps of supplying a blow-off steam charge (Sh) via the inlet (7) to the container (6) and collecting the latter in the internal volume (2) of the container. In this case, the charge (Sh) may be held in a gravitational field. It is possible to recover energy from a portion of the blow-off steam charge (Sh) by condensation thereof. The condensation results in a stream from said portion to an outlet (10) which is at a lower gravitational potential. Via the outlet (10), it is possible to discharge a portion of the charge (Sh) from the internal volume (2) of the container (6) at a lower gravitational potential.

One of the two sealed compartments contacts one side of the blood bag and the other compartment is folded over to contact the other side of the blood bag. The transparent compartments allows an operator to verify at any time whether the solution is in a solid state, and the flexibility of the compartments eases the proper positioning of them around a blood bag.

  • Publication number: 20120111538
    Abstract: A heat dissipation structure mounted onto an electronic element to dissipate heat. The heat dissipation structure includes a heat absorber connected with the electronic element and a heat sink. The heat absorber has a hollow first chamber to hold a working fluid. The heat absorber and heat sink are interposed by a plurality of first conduits. When the heat absorber absorbs heat generated by the electronic element through a contact surface, the working fluid held therein is vaporized into vapor. The vapor enters a second chamber of the heat sink through the first conduits and performs heat exchange with a cooling surface of the heat sink to be converted into the working fluid again. The working fluid is conveyed via a capillary structure in the second conduit to the first chamber to form a thermal cycle. The structure of the invention is simpler and can rapidly absorb and dissipate heat.

  • Publication number: 20120097368
    Abstract: A heat exchange chamber for liquid state cooling fluid is provided, which comprises a casing and a thermal dissipation device, the casing has a cavity and the thermal dissipation device is sited in the cavity. A cooling fluid flows through the cavity along a flow direction. The cross-sectional area of the cavity whose direction is perpendicular to the flow direction shows linear increase or non-linear increase gradually along the flow direction, and a part of the cooling fluid vaporizes after flowing through the thermal dissipation device. The chamber along the flow direction shows different pressures, and two phase fluid flows automatically due to the pressure difference. The heat exchange chamber for liquid state cooling fluid could lighten the loading of the pump which is for circulating the cooling fluid, and it also achieve the efficacy of saving energy and raising efficiency.

  • Patent number: 8164901
    Abstract: An efficient method of heat removal from rack mounted computer equipment, network gear and other electronic equipment, consisting of solid heat conducting components in direct contact with the heat generating sources. In particular, this invention is primarily focused on the ability to efficiently and effectively cool computer equipment in standard computer rack cabinets. This invention utilizes a design that retains the general existing form factor of the rack mounted computer equipment, but uses direct contact heat transfer to a metal heat transfer conduit (Copper, Aluminum or other metal or efficient heat conducting material) contained within the computer equipment chassis. Furthermore, it is thermally coupled to an external rack mounted solid-to-fluid heat exchanger as an efficient method of heat transfer and removal. This is much more efficient than air as heat transfer medium which it the common method of heat removal from existing standardized rack mounted computer equipment.
