Problems solved by technology

However, there will be the following problems in this way: as the use time goes on, the dust on the dust-proof parts will accumulate more and more, resulting in less and less air entering the air duct, and the heat dissipation effect will become worse. The lifespan is shortened after the heat dissipation becomes poor, and even the components are directly damaged

Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0027] It should be noted that in the embodiments of the present invention, if the directional indication (such as up, down, left, right, front, back...) is only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0028] In addition, in the present invention, descriptions such as "first", "second...

Abstract

The present invention discloses a projector and a heat-dissipation control method of the projector. The projector comprises a shell body, an air duct is formed in the shell body, an air inlet of the air duct is covered with a dustproof component, and the air duct is provided with a first temperature sensor, a second temperature sensor and a fixed heat source. The first temperature sensor is arranged near the air inlet of the air duct, the fixed heat source is arranged away from the air inlet, and the second temperature sensor is arranged adjacent to the fixed heat source. The projector is also provided with a processor, and the processor is electrically connected with the first temperature sensor and the second temperature sensor. The processor compares a temperature difference between a first temperature detected by the first temperature sensor and a second temperature detected by the second temperature sensor with a preset threshold, and if the temperature difference is more than the preset threshold, the using power of components of the projector is reduced. Therefore, the service life of the projector is improved and the damage rate of the components is reduced.

Description

technical field [0001] The invention relates to the technical field of projection, in particular to a projector and a heat dissipation control method thereof. Background technique [0002] The heat dissipation method of the projector is generally to install a fan in the air duct, blow the air through the fan, and the components of the projector, such as the light source, display screen, power supply, processor, etc., dissipate heat into the air through air convection. [0003] In order to prevent dust in the air now, dust-proof components are usually added at the entrance of the air duct. However, there will be the following problems in this way: as the use time goes on, the dust on the dust-proof parts will accumulate more and more, resulting in less and less air entering the air duct, and the heat dissipation effect will become worse. After the heat dissipation becomes poor, the life is shortened, and even the components are directly damaged. Contents of the invention ...
