AI Technical Summary

Problems solved by technology

While solving the heat dissipation problem, the heat dissipation mechanism produces another problem, that is, noise, especially at the air outlet of the heat dissipation air duct of the bulb cooling mechanism, there will be sharp noise generated by the vortex of the air outlet, and the noise will increase with the wind speed. Increase and increase, causing sound pollution to the use environment
Due to its structural reasons, the projectors of the prior art generally have large or small noises

Embodiment Construction

[0012] The projector bulb cooling mechanism with the air outlet of the air duct and the noise reduction net of the present invention is arranged in the housing of the projector, and is mainly used to cool the bulb installed in the housing, and discharge the heat emitted by it out of the machine in time, and as far as possible It is possible to reduce the noise generated by the cooling air flow.

[0013] Referring to Fig. 1, Fig. 1 is a schematic diagram of the main structure of the projector with the projector bulb cooling mechanism provided by the air outlet of the air duct and the noise reduction net of the present invention. As shown in the figure, 1 is the projector casing, 11 is the air outlet of the whole machine installed on the casing, 2 is the light engine, 3 is the light bulb, 4 is the light bulb cooling air duct, 5 is the vortex fan, and 6 is the axial flow Fan, 7 is an exhaust air duct. The light bulb heat dissipation air duct 4 is arranged horizontally to surroun...

Abstract

The projector lamp bulb cooling mechanism with muffling net in the outlet of wind channel includes one lamp bulb heat dissipating air duct, one vortex flow fan and one axial fan. The lamp bulb heat dissipating air duct is transversely set to surround the lamp bulb, and has one air inlet and one air outlet on two ends. It features the muffling net in the outlet of the heat dissipating air duct and comprising at least two layers of metal or nylon wire net in different density. The projector lamp bulb cooling mechanism has greatly reduced noise in the outlet, capacity of silencing work environment and raised projector use effect.

Description

technical field [0001] The invention relates to a projector, in particular to a projector bulb cooling mechanism with an air outlet of an air duct and a sound-absorbing net. Background technique [0002] Projectors are widely used in education, business and home. A common projector generally includes a casing and a light engine, a circuit board, a lighter, a light source and a corresponding heat dissipation mechanism arranged in the casing. According to the number of lenses used in the light engine, projectors can be divided into single-lens projectors and three-lens projectors. In terms of design, the white light generated by the light source is generally separated into red, green and blue three-color light, and the three-color light is modulated by three liquid crystal light valves respectively. The modulated three-color light is different according to the design of single lens or three lenses. processed in different ways. In a single-lens projector, the three-color lig...
