Description

Technical Field

[0001] The invention relates to the technical field of radiators, and in particular to an embedded multi-faceted radiator for a projector. Background Art

[0002] A radiator is a commonly used heat dissipation device, and its material is usually aluminum or other materials. After the radiator comes into contact with a heat-generating object, the heat-generating object transfers heat to the radiator through heat conduction. The mounting base plate at the bottom of the radiator first contacts the heat-generating object and further transfers the heat to a plurality of heat dissipation fins integrally formed on the upper part of the mounting base plate for heat conduction and heat dissipation. The radiator has the advantages of simple structure, convenient use, relatively low economic cost and use cost, and is widely used in industrial fields, such as heat conduction and heat dissipation of mechanical equipment. However, the existing radiator still has the following problems during use: the thickness of the heat dissipation fins is relatively thin, the structural strength is not high, and it is easy to deform and damage. After deformation and damage, the heat dissipation fins integrally formed with the mounting base plate are inconvenient to dismantle and replace relative to the mounting base plate and mechanical equipment, which affects the use of the radiator.

[0003] Publication No. (CN214173070U) An embedded radiator, characterized in that it includes a mounting base plate and heat dissipation fins, the upper end of the mounting base plate is provided with a plurality of heat dissipation fins, the upper end of the mounting base plate is provided with an embedding seat groove, the bottom ends of the plurality of heat dissipation fins are integrally formed with a connecting base plate, both left and right ends of the upper end of the mounting base plate are fixedly connected with limiting edge blocks, the limiting edge blocks and both left and right ends of the connecting base plate are provided with connecting through holes, the upper end of the mounting base plate is located outside the heat dissipation fins, a connecting frame is provided around it, and limiting embedding grooves are provided on both left and right ends of the two sides of the connecting frame. The heat sinking parts are connected by the screw threading device, and the screw threading device is connected to the heat sinking part, and the heat sinking part is connected by the screw threading device, and the heat sinking part is connected by the screw threading device.

[0004] The above-mentioned embedded radiator is easy to install, but since the objects that the radiator dissipates heat for are of different sizes, the scope of use of the embedded radiator is relatively single. For example, existing projectors are of different sizes, so different sizes and adapted to projectors of different sizes are required. A small projector can be used in a large embedded radiator, but since the projector is small, the heat dissipation effect is not ideal, and it also affects the stability of the projector in the embedded radiator, which reduces the practicality of the existing embedded radiator and increases the heat dissipation cost when dissipating heat for projectors of different sizes. Summary of the invention

[0005] The object of the present invention is to provide an embedded multi-surface radiator for a projector to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: an embedded multi-faceted radiator for a projector, comprising: A radiator box, wherein the front side of the radiator box is open, a radiator door panel is movably sleeved on the front side of the radiator box, and a movable heat dissipation component is provided on the top of the radiator box; A projector fixing assembly is provided at the bottom of the inner cavity of the radiator case, and the projector fixing assembly includes a rotating connection block, an adjustable telescopic rod, a fixed splint, a first spring and a connecting rubber block.

The first heat sink, the mounting plate, the second spring and the lifting guide rod are arranged on the top of the radiator housing, and since the first heat sink is connected to the radiator housing by the second spring, the lifting guide rod and the mounting plate, it is convenient to adjust the distance between the bottom of the first heat sink and the bottom of the inner cavity of the radiator housing, so that the first heat sink can perform heat dissipation treatment on projectors of different heights, and since the first heat sink is in contact with the top of the radiator housing, when the first heat sink descends, the dust on the outer side of the first heat sink can be cleaned to the top of the radiator housing, so that the first heat sink is always kept clean.

[0008] As a further improvement of the present invention, the top of the radiator housing is provided with a plurality of movable heat dissipation components, which are evenly distributed on the top of the radiator housing.

[0048] Working principle: When using the device, hold the moving rod 505 to push the radiator door panel 2 to move upward along the top of the radiator case 1. At this time, since the upper part of the radiator door panel 2 is connected to the sliding block 502 by the jump adjustment rod 504, and the sliding block 502 is located in the inner cavity of the sliding track 501, the sliding block 502 is driven to move along the inner cavity of the sliding track 501. Since a cleaning scraper 503 is installed on the top of the sliding block 502, the cleaning scraper 503 is driven to move on the top of the radiator case 1; then move the moving rod 505 to the top of the limiting plate 507, push the moving rod 505 to move in the moving groove 506, and place the moving rod 505 on the top of the limiting plate 507, so as to fix the position of the radiator door panel 2. At this time, the cleaning scraper 503 moves to the front side of the top of the radiator case 1; The projector to be used is placed in the inner cavity of the radiator housing 1, so that the four fixing clamps 303 and the connecting rubber block 305 clamp the four edges of the projector respectively. At this time, the bottom of the first heat sink 401 contacts the projector, and the first heat sink 401 is lifted up by the top of the projector to squeeze the second spring 403. The second heat sink 6 and the third heat sink 7 are used to conduct the heat of the bottom of the projector to the top of the radiator housing 1. Since the radiator housing 1 is in contact with the first heat sink 401, it is convenient to conduct heat to the bottom of the radiator for heat dissipation, and the first heat sink 401 is used to dissipate heat from the top of the projector, so that multi-faceted heat dissipation of projectors of different sizes is achieved, thereby improving the heat dissipation efficiency. When the projector is used for a long time, since the first heat sink 401 is exposed to the outside, the first heat sink 401 is easily contaminated with external dust. After the projector is used, the projector is taken out of the inner cavity of the heat sink box 1. At this time, the elastic force of the second spring 403 is used to drive the first heat sink 401 to move downward. Since the first heat sink 401 is in contact with the top of the heat sink box 1, the position where the first heat sink 401 is in contact with the top of the heat sink box 1 is used to remove the dust contaminated on the outside of the first heat sink 401, so that the dust stays on the top of the heat sink box 1. Then remove the moving rod 505 from the top of the limit plate 507, push the radiator door panel 2 downward, now the radiator door panel 2 moves downward, and use the jump adjustment rod 504 to drive the sliding block 502 to move backward on the sliding track 501, so that the cleaning scraper 503 on the sliding block 502 also moves backward, and use the bottom of the cleaning scraper 503 to contact the top of the radiator case 1, so that the dust remaining on the top of the radiator case 1 is removed from the top of the radiator case 1.
