Description

Technical Field

[0001] The utility model relates to the technical field of outdoor projection, in particular to an outdoor projection heat dissipation device. Background Art

[0002] Projection refers to the use of a set of light rays to project the shape of an object onto a plane, which is called "projection". The image obtained on the plane is also called "projection". Projection can be divided into orthographic projection and oblique projection. Orthographic projection means that the center line of the projection line is perpendicular to the projection plane, and the projection center line is not perpendicular to the projection plane, which is called oblique projection and can be used outdoors.

[0003] Existing projection equipment generates a large amount of heat during use, which will have an adverse effect on the internal components and reduce the service life of the equipment. Therefore, it is necessary to further enhance the heat dissipation effect.

[0004] In the prior art, a Chinese patent with publication number CN210514916U is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a projection heat dissipation device, which relates to the technical field of projection equipment production and manufacturing. In order to solve the problem that the existing projection equipment generates a large amount of heat during use, this heat will have an adverse effect on the internal part and cause the service life of the equipment to be reduced, so the heat dissipation effect needs to be further enhanced. A projector lens is arranged at the middle position of the front end face of the projector, a front heat dissipation surface of the projector is arranged on the front end face of the projector, and two front heat dissipation surfaces of the projector are arranged, a heat dissipation hole is arranged on the front end face of the projector, and two heat dissipation holes are arranged, a slide is arranged on the outer wall of the front heat dissipation surface of the projector, a movable shield is arranged on one side of the front heat dissipation surface of the projector, a limit rod is arranged on the other side of the front heat dissipation surface of the projector, and four projector fixing feet are arranged under the projector. However, when the device is in humid air, moisture is easily sucked into the inside of the device during the heat dissipation process, thereby causing the electronic components inside the device to become damp, thereby affecting the service life of the electronic components.

[0045] The working principle of the outdoor projection heat dissipation device is described in detail below.

[0046] like Figure 1-Figure 5 As shown, after the user installs or places the device outdoors, when heat dissipation is required, the user can turn on the heat dissipation fan 7, and the heat dissipation fan 7 can suck air from one side. The air passes through the filter 201 and then enters the inside of the heat dissipation box 2, and then enters the inside of the shell 1, thereby achieving heat dissipation. During the use of the device, the humidity sensor 12 can be used to detect the humidity of the air around the device. When the humidity is detected to be higher than a certain standard, the waterproof frame 6 is in a state of completely covering one side of the heat dissipation box 2. At this time, the heat dissipation fan 7 is turned on, and humid air enters the inside of the heat dissipation box 2. The waterproof frame 6 can be used to remove moisture contained in the air. The moisture in the heat sink 2 and the housing 1 is adsorbed to prevent water from entering the heat sink 2 and the housing 1 and affecting the electronic components therein, thereby achieving a waterproof effect. When it is detected that the humidity has dropped to a certain standard, the detection result can be transmitted to the controller 4, and the controller 4 can control the motor 9 to start working, and use the motor 9 to drive the screw rod 901 to rotate, while driving the connecting block 1101 and the slide plate 11 to move toward one end, and at the same time, the waterproof frame 6 can be automatically pushed toward one end, and the waterproof frame 6 is compressed to expose most of one side of the heat sink 2, thereby increasing the air flow speed, facilitating the dry air to quickly enter the heat sink 2, and dissipate the heat inside the housing 1.

[0047] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
