A projector comprises a housing, a power supply module, a projection lens, an optical engine module, a light source module, a fan and a wind guiding block. A first space, a second space and a third space are formed in the housing. The projection lens and the optical engine module are arranged in the first space. The power supply module is arranged in the second space. The light source module and the fan are arranged in the third space. A wind inlet and a wind outlet are formed in the housing. The first space and the second space communicate with the wind outlet. The heat generated by the optical engine module during work flows to the second space. The heat generated by the power supply module during work flows to the third space. The wind guiding block guides the heat of the third space to the first space and the second space and mix the heat with cooling air at the wind inlet. The fan discharges heat of mixed wind out of the housing through the wind outlet.
Description
technical field [0001] The present invention relates to a projector. Background technique [0002] At present, projectors generally reduce the temperature of the projector by increasing the number of fans or the number of air inlets and outlets. Although the temperature of the projector is reduced by the above method, the cost of the product is increased, and the projector is also increased. Working noise. Contents of the invention [0003] In view of the above, it is necessary to provide a projector with better heat dissipation effect. [0004] A projector includes a casing, a power supply module, a projection lens, an optical engine module, a light source module, a fan, and an air guide block. A first space and a first space are formed in the casing. Two spaces and a third space, the projection lens and the optical engine module are placed in the first space, the power supply module is placed in the second space, the light source module and the fan are placed In the t...
