Methods for cooling an illumination device are disclosed. The illumination device comprises a cathode, an anode and a cooling fan. A variation of a lamp voltage of the illumination device is first detected. The lamp voltage is the voltage difference between the cathode and the anode, and the variation of the lamp voltage is derived from comparing the lamp voltage which is detected with the lamp voltage at the first time the illumination device is used. A rotational rate of the cooling fan is then adjusted according to the variation of the lamp voltage.

Illumination devices with cooling fans and cooling methods thereof

A temperature control method for a display device comprising a lamp box for emitting a light, a fan for cooling down the display device and a digital image device for receiving the light from the lamp box and forming an image, comprises acquiring an operating time of the lamp box; calculating a temperature offset in accordance with the operating time of the lamp box; acquiring a temperature value of the digital image device; calculating a control value in accordance to the temperature value and the temperature offset; controlling the fan in accordance with the control value.

Temperature control method and device for a display device

A velocity-profile modifying device is located between a heat component and an air pouring apparatus. The air pouring apparatus pours the air into the heat component via an air moving track. The velocity-profile modifying device is set at the air moving track and is used for modifying a first velocity-profile of airflow by the air pouring apparatus to a second velocity-profile and further for making the air distribute evenly toward the heat component. By providing the velocity profile modifying device, a better distribution of the airflow toward the heat component and a stable temperature status of the heat component can be achieved.

Velocity profile modifying device for nozzles

The invention discloses an electronic equipment including a cooling module, a receiving module, and a controller. The receiving module is used for receiving at least one geographic parameter relative to a location where the electronic equipment is located. The controller is used for controlling the cooling module with a predetermined manner corresponding to the at least one geographic parameter.
