Projector

Abstract

The invention discloses a projector, comprising a machine shell, an optical module, a light source module, a blowing fan and an axial fan. The machine shell comprises a first air outlet, a second airoutlet and an air inlet; the axial fan and the blowing fan are arranged corresponding to the two sides of the optical axis of the light source module; when the blowing fan operates, the initial airflow enters inside the chassis from the air inlet, flows through the optical module and enters the air inlet surface of the blowing fan, and generates established airflow on the air outlet surface of theblowing fan to carry out heat dissipation on the light source module; the axial fan forms an angle with the side edge of the machine shell; and the axial fan discharges the airflow around the light source module directly outside the machine shell through the first air outlet and / or the second air outlet.

Description

Technical field [0001] The present invention relates to a projector, and particularly relates to a projector that achieves a good heat dissipation effect through an optimized design of a fan setting mode. Background technique [0002] In general meetings, video viewing, or exhibitions, projectors are often used to project presentations, films, images, and other data on the screen. The projectors currently on the market mainly use projection technologies such as three-chip liquid crystal projection (3LCD), digital light processing (DLP), and liquid crystal on silicon (LCoS). [0003] Although the color separation and projection principles of the above-mentioned projection technologies are different, most of them use high-pressure halogen lamps or mercury bulbs as white light sources, and then separate the white light into red (R) through dichroic mirrors, panels, or color wheels. , Green (G), blue (B) three primary colors. In addition, as users’ requirements for “portability” are ...

Problems solved by technology

[0007] However, if figure 1 As shown, since the position of the second fan 92 in the casing 90 needs to be designed in accordance with the flow channel formed by the partition plate 97, the path of the entire air flow is not smooth, and even a large angle is generated near the light source module 95. Backflow, causing the heat of the hot air to gradually accumulate near the light source module 95 and cannot be removed smoothly

These undischarged hot airflows are likely to cause damage to the electronic components in the projector 9 due to high heat, seriously affecting the normal operation of the projector 9
