Patent number: 7798204Abstract: A centrifugal condenser in an engine has a stacked arrangement of interleaved plates surrounding a central core. Exhaust steam from the engine is directed through interior cavities of the plates while external cooling air from intake blowers circulates over outer surfaces of the plates to cool the plates and condense the steam on the opposite inner side of the plates. The water condensation is returned to a collection pan or sump for subsequent use in the engine.Type: GrantFiled: April 24, 2006Date of Patent: September 21, 2010Assignee: Cyclone Power Technologies, Inc.Inventor: Harry Schoell

Patent number: 7760501Abstract: A heat dissipation apparatus includes a heat sink (30) and a fan (50) mounted on the heat sink. The heat sink includes a plurality of radial fins (311, 331). An air channel (312, 332) is defined between every two adjacent fins. Each of the fins includes a main body (331, 331) and an airflow guiding flange (314, 334) extending upwardly and outwardly from a top side of the main body. The airflow guiding flange is twisted in a radial direction, such that an included angle between the airflow guiding flange and the main body is gradually increased from an outer side (318, 338) towards an inner side (317, 337) of the main body. The fan is used to generate airflow towards the heat sink. The airflow is guided into the air channels between the fins via the airflow guiding flanges.Type: GrantFiled: November 7, 2008Date of Patent: July 20, 2010Assignees: Fu Zhun Precision Industry (Shen Zhen) Co., Ltd., Foxconn Technology Co., Ltd.Inventors: Xin-Xiang Zha, Shu-Min Li, Shu-Yuan Xu
