Description

a projector

technical field

The utility model relates to the technical field of projection equipment, in particular to a projector.

Background technique

We know that in projection equipment, according to the imaging principle of the projector, extremely high brightness is required when the projector projects the input signal. In order to ensure such a high brightness output, the projector must be realized by using a high-power light source. After working for a long time, it is bound to generate high heat inside the machine. In addition to the heat generated by the projector's light source, the projector's power supply also generates a lot of heat during operation. The heat generated by the projector bulb, imaging system, power supply, etc. is gathered in the small space inside the machine. The high temperature generated not only affects the normal use of the projector, but also greatly shortens the service life of internal components. At present, with the increasing development of electronic technology, more and more projection devices are beginning to be lightweight and miniaturized, which poses a relatively high difficulty in the layout of the internal heat dissipation system. How to release more heat generated by equipment in a small space is an urgent problem to be solved at present.

On January 4, 2017, the State Intellectual Property Office published a utility model patent with the publication number CN205862079U titled "A Cooling System and Projection Device". The utility model patent provides a cooling system and projection device . The heat dissipation system provided by the utility model includes a first heat dissipation device and a second heat dissipation device. Wherein, the first heat dissipation device includes a first air outlet device, a first heat sink, and a first heat conduction component, and the first air outlet device and the first heat conduction component are respectively connected to the first heat sink. The second heat dissipation device includes a second air outlet device, a second heat sink and a second heat conduction assembly, and the second air outlet device and the second heat conduction assembly are respectively connected to the second heat sink. The first heat conduction component and the second heat conduction component form an installation portion for installing the heat source. The heat dissipation system provided by the utility model can solve the heat dissipation problem of a relatively high-power heat source within a certain volume. The projection device provided by the utility model includes the heat dissipation system provided by the utility model.

For some projection equipment that can be placed on the table and installed and used at any time, the usual habit of users is to put away the projection equipment immediately after using and shutting down the projection equipment, which will immediately cut off the power of the projection equipment. The heat dissipation system inside the projection device will not continue to work after power on, but after the projector has been used for a period of time, the heat generated by it has not been completely dissipated by the heat dissipation system, and after the user powers off the projection device, the heat dissipation system will not continue to work. To dissipate heat for the projector, long-term use will affect the projector, affect the normal use of the projection equipment, and will greatly shorten the service life of internal components.
