Patent number: 7179048Abstract: A cooling apparatus with a mesh structure for cooling a lampwick of a projector. The cooling apparatus includes a blower, an adjustable air duct disposed at an outlet of the blower. The adjustable air duct further includes an air duct portion, a guiding portion, and a mesh structure. The blower blows cooling air to the air duct that is directly formed on the blower or installed on the blower with a separate air duct. The guiding portion is configured at an outlet of the air duct. The mesh structure couples to the guiding portion to move a lower portion of the guiding portion by gravity so that most part of the cooling air is blown to the lampwick through an upper portion of the guiding portion.Type: GrantFiled: December 23, 2004Date of Patent: February 20, 2007Assignee: Coretronic CorporationInventors: Jin-Shu Huang, Shang-Hsuang Wu, Nien-Hui Hsu

Patent number: 7149041Abstract: An optical engine includes a light source, an optical main body and a projection lens. The optical main body includes a reflective light valve, a case, a first heat-dissipating device and a heat-insulating device. The reflective light valve reflects the incident light beam to form an image light beam or a dumped light beam that is not projected into the projection lens. The case encloses the light paths of the incident light beam, the image light beam and the dumped light beam. An opening is on the case for the dumped light beam to be projected into. A first heat-dissipating device is fixed on the case and covers the opening for removing the heat generated by the dumped light beam. A heat-insulating device is disposed between the first heat-dissipating device and the case for preventing the heat conduction between the first heat-dissipating device and the case.Type: GrantFiled: April 19, 2005Date of Patent: December 12, 2006Assignee: Coretronic CorporationInventors: Nien-Hui Hsu, Yu-Min Kuo, Wen-Hsien Su, Shang-Hsuang Wu

Patent number: 7144118Abstract: An intake structure, installed in a projection apparatus having heating elements, includes an intake port on the casing, air duct and an exhaust fan near the heating elements. The inlet of the air duct is connected to the intake port, and the outlet is disposed at a side of the heating elements. The air stream from the intake port is directed though the air duct for concentrating the air stream to the heating elements inside of the projection apparatus. Thus, it can be provided the maximum cooling effect and enhanced cooling efficiency for heating elements.Type: GrantFiled: May 24, 2004Date of Patent: December 5, 2006Assignee: Coretronic CorporationInventors: Nien-Hui Hsu, Shang-Hsuang Wu, Wen-Hsien Su

Patent number: 7018049Abstract: A projection cooling apparatus comprises a first cooling path and a second cooling path. The first cooling path includes a temperature sensor and an exhaust fan respectively installed in an inlet and an outlet of the first cooling path. The second cooling path includes a temperature sensor, a power supply unit, and a guiding fan. According to the detecting temperature resulted from the change of power supply and the environmental temperature, the temperature sensors of the first and second cooling path control the rotational speed of two sets of the fans to reach the best cooling effect, reduce the noises and extend the lifetime of the fan.Type: GrantFiled: September 9, 2003Date of Patent: March 28, 2006Assignee: Coretronic CorporationInventors: Shang-Hsuang Wu, Nien-Hui Hsu, Ching-Chung Nien

Patent number: 6846096Abstract: The present invention discloses a partition is incorporated into the case of the projector so as to separate the optical system and the circuitry system. A circuitry fan is used to cool the circuitry system. The optical system is cooled by a suction fan. The cooling air is drawn in by the suction fan and directed to a lamp case through an air duct so as to cool a burner within the lamp case. The heat air is then directed to manifold duct. A first outlet of the manifold duct is directed through an exhausting duct to an exhausting fan. The other outlet of the manifold duct is directed to the circuitry fan. As a result, the heated air is discharged out of the case by those two cooling fans so as to evenly discharge the heated airflow from the lamp case, reducing the heat load of the fan and prolongs the lifespan of the fan.Type: GrantFiled: March 18, 2003Date of Patent: January 25, 2005Assignee: Coletronic CorporationInventors: Nien-Hui Hsu, Shang-Hsuang Wu
