Patent number: 6397936Abstract: A freeze tolerant condenser (106) for a two-phase heat transfer system is disclosed. The condenser includes an enclosure (110) and a porous artery (112) located within and extending along the length of the enclosure. A vapor space (116) is defined between the enclosure and the artery, and a liquid space (114) is defined by a central passageway within the artery. The artery includes a plurality of laser-micromachined capillaries (130) extending from the outer surface of the artery to its inner surface such that the vapor space is in fluid communication with the liquid space. In one embodiment of the invention, the capillaries (130) are cylindrical holes having a diameter of no greater than 50 microns. In another embodiment, the capillaries (130′) are slots having widths of no greater than 50 microns. A method of making an artery in accordance with the present invention is also disclosed.Type: GrantFiled: May 12, 2000Date of Patent: June 4, 2002Assignee: Creare Inc.Inventors: Christopher J. Crowley, Nabil A. Elkouh

Publication number: 20020039487Abstract: A humidifier includes a base defining an evaporation cavity, a water supply is supported on the base and has a discharge opening communicating with the evaporation cavity and is adapted to maintain a given level of water therein. A humidification unit is removably mounted on the base and includes a heating element projecting into the cavity with a wicking sleeve surrounding the element and into the cavity to wick water therefrom. Energization of the heating element causes evaporation of the water that has been wicked from the cavity. The resulting vapor is discharged through an exhaust grill above the cavity.Type: ApplicationFiled: May 7, 2001Publication date: April 4, 2002Inventor: Chi-Hsiang Wang

Patent number: 6333009Abstract: A heat transfer system is provided, adapted to transfer heat from the flame of the oil lamp to fuel contained within the oil lamp. The heat transfer system has a heat absorbing region disposed near the flame, and a heat dissipating region disposed within the container, connected to the heat absorbing region by a thermally conductive path. If the fuel contains a fragrance, heating the fuel enhances the amount of fragrance volatilized from the fuel.Type: GrantFiled: May 11, 2000Date of Patent: December 25, 2001Assignee: Noville, Inc.Inventor: Gerald Herbert Allison

Publication number: 20010020450Abstract: An evaporation device 2 is disclosed for the evaporation of volatile substances, in particular insecticides and aromatics, which includes a housing 13 which contains a heating element and a container 50 for a substance to be evaporated. This container 50 contains a wick which is associated with the heating element with a wick end 30 protruding from container 50. The heating element can be longitudinally displaced near the container 50 in the housing 13 relative to the wick end 30 to adjust the degree of evaporation. According to the invention, the heating element is carried on a movable heater assembly that can be displaced longitudinally in the housing relative to the wick end. The movable heater assembly can be fixed in different positions relative to the wick end 30 and the longitudinal direction of the wick axis for the adjustment of the degree of evaporation.Type: ApplicationFiled: December 18, 2000Publication date: September 13, 2001Inventor: Pedro Queiroz Vieira

Patent number: 5771845Abstract: A liquid is vaporized by a device having at least one porous substrate exposed to a certain ambient pressure, means for supplying the substrate with liquid in order for it to be loaded with liquid starting from an upstream portion of the substrate, and at least one energy source for heating the substrate so that at least some of the liquid is vaporized. According to the invention, the means for supplying the substrate with liquid may include means for pressurizing the liquid to a pressure greater than ambient pressure, thereby creating a flow-rate greater than the flow-rate induced by capillarity and vaporization of the liquid alone when the substrate is held in a horizontal position. The invention may be applied to the production of water-vaporization equipment, particularly with electrical or gaseous energy supply.Type: GrantFiled: April 8, 1996Date of Patent: June 30, 1998Assignees: Gaz De France, Cogia, SuperbaInventors: Jacques Pistien, Jean-Louis Giazzi, Robert Desage, Philippe Deblay
