[0003] There are many types of power controllers, most of which are embedded power controllers used in LED display screens. The power controllers on the market currently need to be controlled continuously, so they are all equipped with relevant cooling structures. Among them, the air-cooled cooling structure is simple, easy to install and more suitable for cooling electronic products. However, the current air-cooled cooling structure can easily blow dust and moisture into the power controller, which can easily cause damage to electronic components. In addition, after the current power controller is installed in the chassis, its air inlet is not necessarily connected to the air inlet of the chassis, which causes the air cooling structure of the power controller to have poor air intake, resulting in poor air cooling effect.

[0037] like Figure 4-5 As shown, it is particularly special that the flange mounting plate 5 is vertically fixedly mounted on the end of the connecting hose 15, and a connecting hole 51 is provided at the top and bottom of the flange mounting plate 5, and the connecting hole 51 is connected to the inner cavity of the connecting hose 15, and an annular mounting cavity 52 is provided at the top and bottom of the flange mounting plate 5, and three fixing rods 53 are fixedly installed between two opposite inner cavity walls of the annular mounting cavity 52, and the three fixing rods 53 divide the annular mounting cavity 52 into three fan-shaped spaces with the same specifications, and a plurality of positioning and mounting mechanisms 6 rotate and slide in the corresponding fan-shaped spaces, and the inner and outer cavity walls of the annular mounting cavity 52 are provided with arc-shaped slide grooves 54, and a plurality of positioning and mounting mechanisms 6 include positioning seats 61, and arc-shaped sliders 62 are fixedly installed at both ends of a plurality of positioning seats 61, and a plurality of arc-shaped sliders 62 are respectively slidably mounted in the corresponding arc-shaped slide grooves 54, and a plurality of arc-shaped sliders 62 are provided with strip-shaped docking holes 63 at the top and bottom ends, and a third screw 64 is slidably installed in a plurality of strip-shaped docking holes 63;

[0038] like Figure 1-3As shown, what is particularly special is that the two auxiliary mounting mechanisms 7 each include a mounting plate 71, and the two mounting plates 71 are respectively tiltedly arranged at the top and bottom of the outer shell 1, and the two mounting plates 71 are each provided with a panel groove 72 on the side away from the outer shell 1, and a plurality of rotating rollers 73 of uniform specifications and distributed in an equidistant linear array are rotatably installed between the two opposite inner groove walls of the two panel grooves 72, and a wrapping belt 74 is arranged in each of the two panel grooves 72, and the two wrapping belts 74 are respectively wrapped around the outer roller walls of the corresponding plurality of rotating rollers 73, and the wear of the mounting plates 71 can be reduced by the wrapping belt 74, and springs 75 are each tiltedly installed between the four corners of the two mounting plates 71 and the outer shell 1, and elastic restoring force can be obtained through the deformation of the springs 75 and fed back to the outer shell 1, so that the outer shell 1 is firmly squeezed and limited in the reserved hole position of the chassis.

[0039] Working principle of the present invention:

[0040] The first step is to insert the end of the shell 1 away from the control panel 2 into the chassis. At this time, the two auxiliary installation mechanisms 7 at the top and bottom of the shell 1 will contact the upper cavity top and lower cavity bottom of the reserved hole in the chassis. At this time, the two surrounding belts 74 rotate by themselves and cooperate with the bottom spring 75 to be squeezed and compressed, so that the shell 1 can be smoothly inserted into the reserved hole of the chassis under the premise of reducing collision and ensuring force extrusion reinforcement. Then place the motor 4 on the top of the mounting seat 13, and threadedly install a number of second screws to fix the motor 4, and then insert the unused drying filter frame 3 into the socket 14. At this time, the lower bottom of the drying filter frame 3 is flush with the lower bottom of the socket 14. Then start the motor 4 to drive the threaded shaft 41 to rotate, and then drive the threaded ring 42 to rotate synchronously (due to the sliding friction between the threaded ring 42 and the threaded shaft 41). At this time, the threaded ring 42 is restricted from rotating, and the threaded ring 42 is forced to only drive the extrusion plate 44 to move linearly downward through the connecting force arm 43, so that the square cavity at the bottom of the extrusion plate 44 is just stuck on the top of the drying filter frame 3. At this time, there is no need to interfere with the threaded ring 42. Finally, the flange mounting plate 5 is moved to the air inlet of the chassis, and finally the connecting hole 51 is connected with the air inlet of the chassis, and then several positioning seats 61 are slid respectively. At this time, the arc-shaped sliders 62 at both ends of the positioning seats 61 will slide in the corresponding arc-shaped sliding grooves 54, and the third screws 64 in the positioning seats 61 will also rotate and slide synchronously, and finally the third screws 64 are slid respectively, so that the third screws 64 slide in the corresponding strip docking holes 63, until the third screws 64 are opposite to the mounting hole positions reserved at the air inlet of the chassis, and then the detachable docking is completed;

[0041] The second step is to start the fan 12. The fan 12 directly introduces external air from the air inlet of the chassis through the connecting hose 15. However, at this time, the air entering the connecting hose 15 still contains solid particle impurities and a large amount of water vapor. When the external air enters the mounting seat 13, it will pass through the filter screen 31 and the aluminum oxide plate 32 in the drying filter frame 3, wherein the filter screen 31 can intercept large particles of dust and foreign matter in the air inlet channel to prevent solid particles and foreign matter from entering the housing 1 and affecting the normal use of the power controller body 16. The aluminum oxide plate 32 can absorb the water vapor carried in the incoming air without affecting the normal air intake, so that the air entering the housing 1 is dry, ensuring that the power controller body 16 will not be affected by the humid air. Since the power controller body 16 works continuously, high-temperature air will be generated and gathered in the inner cavity of the housing 1. When the dry and filtered cold air enters the inner cavity of the housing 1, the high-temperature air will be squeezed out from the heat dissipation covers 11 on both sides to achieve circulating air cooling;

[0042] In the third step, with the long-term use of the filter 31 and the alumina plate 32, the mesh of the filter 31 will be partially or even completely blocked, causing difficulty in air intake, and the alumina particles in the alumina plate 32 will also absorb too much water and become saturated. At this time, the motor 4 can be started to drive the threaded shaft 41 to rotate, and then drive the threaded ring 42 to rotate. However, at this time, since the extrusion plate 44 is stuck on the top of the dry filter frame 3, and the dry filter frame 3 is inserted into the socket 14, the threaded ring 42 cannot rotate. The extrusion plate 44 can only be driven by the connecting force arm 43 to push the dry filter frame 3 and the filter 31 and the alumina plate 32 to descend in height, so that the unblocked mesh of the filter 31 and the unsaturated alumina particles enter the air inlet channel, ensuring that the functions of the filter 31 and the alumina plate 32 can be effectively maintained for a long time.

The preferred embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification.
