Problems solved by technology

[0009] The noise generated by the unit is greatest when it is heavily loaded (such as is the case when it displays or projects high-quality images), or when the unit is placed in an environment with high temperatures, which frustrates the user and inconvenience
[0010] Some units reduce the noise by reducing the speed of the fan, but this detracts from the performance of the unit
[0011] Furthermore, in the case of portable devices (assumed to be mobile and usable in any situation (conference, travel)), the user is not able to use said device in an optimal and comfortable way

Abstract

The invention concerns a device (1) comprising: at least one component (7), at least one fan (4) for regulating the temperature of the component (7), a processor (5), and at least one temperature sensor (3), characterised in that the processor (5) is configured to control the direction of rotation of the fan (4) on the basis of the temperature of the component (7) measured by the temperature sensor (3), so as to regulate the temperature of the component (7) and the noise generated by the fan (4). The invention also concerns a method for regulating the temperature in this device.

Description

technical field [0001] The invention relates to a device, the temperature control of which is provided by a mechanical ventilation system. Background technique [0002] Electronic devices typically include at least one fan to control their temperature. [0003] Effective temperature control is integral to maintaining device performance. [0004] In fact, the heating of the components of the device often causes a deterioration of the performance of the device. [0005] This occurs, for example, in the case of electronic devices comprising lighting systems for the display and projection of images. In particular, the quality (and especially the sharpness) of images displayed or projected by the lighting system depends on a suitable temperature regulation of the lighting system. Excessively high temperatures of the components of the lighting system degrade the quality of the images produced. [0006] In the prior art, temperature control of at least one component of an elect...
