摘要： 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.

摘要： 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.

摘要： The invention provides a heat-dissipating system and a control method thereof. The heat-dissipating system has a plurality of fans and is configured for adjusting rotation-speeds of the fans. The control method includes following steps: obtaining a plurality of rotation-speed values of the fans; computing out a rotation-speed reference value according to the rotation-speed values; when the rotation-speed reference value is greater than a first threshold value, decreasing the rotation-speeds of the fans through a corresponding fan control signal; when the rotation-speed reference value is less than a second threshold value, increasing the rotation-speeds of the fans through the corresponding fan control signal.

摘要： A projector includes a housing, an optical engine module, a light source, a system fan and a lamp cooling fan. The housing includes a air vent and an intake. The optical engine module is disposed in the housing. The light source is disposed on one end of the optical engine module for providing light. The light source includes a first side and a opposite second side opposite to the first side. The system fan is disposed adjacent to the first side for generating an airflow flowing from the first side toward the light source. The lamp cooling fan is disposed adjacent to the second side for generating an airflow flowing from the second side toward inside of the light source and the first side. The airflow generated by the lamp cooling fan mixes with the airflow generated by the system fan and then is exhausted through the air vent.
