Problems solved by technology

However, there are multiple components in the projection device that need to dissipate heat. As the number of fans increases, the cost and noise of the projection device will increase, and even the size of the projection device will increase to accommodate multiple fans.

Embodiment Construction

[0041] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0042] Certain terms are used in the specification and subsequent claims to refer to particular elements. Those of ordinary skill in the art will appreciate that manufacturers may refer to the same element by different terms. This description and subsequent patent applications do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. The term "comprising" mentioned throughout the specification and subsequent claims is an open term, so it should be interpreted as "including but not limited to".

Abstract

The invention discloses an electronic device and a heat dissipation control method of the electronic device. The heat dissipation control method comprises the steps that the first threshold value Tm1n of each heating unit is set, the first working temperature value Tn of each heating unit is collected, and whether the first working temperature value Tn of each heating unit is larger than the corresponding first threshold value Tm1n is judged; when the first working temperature value Tn of each heating unit is larger than the corresponding first threshold value Tm1n, the corresponding heating unit is added into an air supply list; the air supply list is read, wherein the air supply list contains M heating units; according to the first working temperature values Tn of all the heating units in the air supply list and the corresponding first threshold values Tm1n, the air supply ratio of all the heating units in the air supply list is determined; according to the air supply ratio, the angle of a drainage plate is adjusted, so that air flow of a first fan is distributed to the M heating units in the air supply list in a guide channel according to the air supply ratio.

Description

technical field [0001] The present invention relates to an electronic device and a heat dissipation control method thereof, in particular to an electronic device and a heat dissipation control method thereof that can dynamically allocate the air volume of one fan without increasing the number of fans and changing the direction of the fans to simultaneously dissipate heat from multiple heating units . Background technique [0002] Recently, the application of projection devices has become more and more widespread. In addition to being used for conference reports in general offices, projection devices are often used in various seminars or academic courses due to their audio-visual playback function. Generally speaking, the projection device has a cooling system, which uses a fan to blow external air into the casing of the projection device to cool the heat generated by the heat source (such as a light source, an optical engine, etc.). [0003] The fans of the existing projec...
