Abstract

The invention provides a cooling system and method of a projector. At least one movable baffle is arranged in an air duct in a shell of the projector. The air duct is formed from an air inlet formed in the shell to an air outlet. The temperature in the shell is acquired; the temperature value is compared with a preset threshold value, the baffle is automatically moved according to the comparison result so as to increase or decrease the air volume in the air duct, and then the temperature in the shell is kept constant. The air volume in the air duct can be increased without directly adjusting the rotating speed of a fan, the dustproof and filtering functions are achieved, the noise reduction function can be achieved, the maintenance frequency of a machine table is reduced, and detachment and installation are more convenient. Unnecessary damage to other people when other people directly make contact with blades of the fan can be avoided.

Description

technical field [0001] The invention relates to the field of projection technology, in particular to a heat dissipation system and method of a projection device. Background technique [0002] In general products of the same type, the air volume can be changed by adjusting the fan speed. When the temperature inside the machine rises, the air volume can only be increased by increasing the fan speed, and eventually more heat will be carried out of the machine through the wind to achieve the effect of cooling. Correspondingly, when the temperature inside the machine table drops, the air volume is reduced by reducing the speed of the fan. Although it is more convenient to adjust the temperature by automatically controlling the fan speed, when the fan speed increases during use, the noise generated by the fan will also increase accordingly. Contents of the invention [0003] In view of the shortcomings of the prior art described above, the purpose of the present invention is t...
