Description

Technical Field

[0002] In the application of modern electronic equipment, cabinets are important equipment storage and protection devices, and often need to house a large number of electronic components and equipment. These electronic devices will generate a lot of heat during operation. If the heat cannot be dissipated in a timely and effective manner, the temperature inside the cabinet will rise, affecting the performance, stability and life of the equipment.

[0003] The passive heat dissipation devices of existing devices basically rely on the principle of hot air rising and cold air falling when dissipating heat, so that the heat generated by the components inside the cabinet during operation and the cold air outside form an air circulation to continuously take away the heat and dissipate it to the surrounding environment, thereby reducing the temperature inside the cabinet. Since the components inside the cabinet work for a long time and generate a large amount of heat, the heat cannot be completely dissipated in time by relying on the natural circulation of hot and cold air, resulting in a gradual increase in the temperature inside the cabinet, causing excessive heat to accumulate in the cabinet, affecting the overall heat dissipation efficiency, and affecting the normal operation and life of the equipment.

[0016] Furthermore, a method for using a cabinet back panel passive heat dissipation device is provided, the cabinet back panel passive heat dissipation device comprising the following steps:

[0017] S1: First, the heat-generating electronic components in the main body are closely contacted or close to the back of the main body. When the electronic components are heated, the hot air generated by the heating of the electronic components will rise from the back of the main body due to the natural convection principle that hot air rises and cold air falls.

[0018] S2: The cold air flows in from below, forming a natural air circulation flow. When hot air is generated inside the main body, it will rise along the guide plate;

[0019] S3: When the hot and cold air circulates, the air circulation can continuously take away the heat inside the main body and dissipate it into the surrounding environment, thereby reducing the temperature inside the cabinet.

[0020] The present invention has the following beneficial effects:

[0021] 1. In the present invention, when hot air rises inside the main body, the hot air will enter the hollow box through the circular hole in the bottom of the hollow box. When the hot air enters the hollow box, the airbag 2 inside the hollow box will expand due to heat and contraction due to heat. When the hot air accumulates inside the hollow box, the airbag 2 will expand due to heat. When the airbag 2 expands, it will push the spring plate 2 to move inside the hollow box. When the spring plate 2 moves, the moving spring plate 2 will drive the wave tube 1, and the wave tube 2 slides with the convex rod shaft. When the convex rod shaft slides, it will slide inside the semi-toothed cylinder. When the spring plate 2 slides to the inner wall of the semi-toothed cylinder, the convex rod shaft will stop sliding. Then, when the spring plate 2 continues to slide through the wave tube 1 and the wave tube 2, The waves on the wave tube will squeeze the plug rod on the surface of the convex rod shaft, and at this time the plug rod will drive the convex rod shaft to rotate along the wave groove on the wave tube, and the convex rod shaft will drive the fixed disk one to rotate through the half-tooth cylinder when rotating, and when the fixed disk one rotates, it will drive several arc plates on one side wall of the fixed disk to rotate, and when the fixed disk one drives several arc plates to rotate, the rotation of the arc plates will break the original static state of the air, promote the mixing and flow of cold and hot air in the main body, thereby enhancing the natural convection effect, and at the same time, the rotation of the arc plates not only accelerates the flow speed of the air in the main body, but also helps to transfer the heat inside the main body to the air faster, and discharge it to the outside of the main body through the air outlet groove, thereby improving the overall heat dissipation efficiency.

[0022] When the cam shaft is driven by the wave tube 1 through the wave tube 2 to slide inside the semi-toothed cylinder, the sliding of the cam shaft will squeeze the spring cylinder inside the semi-toothed cylinder. After being squeezed, the spring cylinder will push the swing plate to move. When the swing plate is pushed by the spring cylinder, the swing plate will be pulled by the rotating plate. At the same time, when the swing plate slides obliquely, the rectangular groove inside the swing plate will slide obliquely upward on the surface of the rotating plate. When the swing plate slides, it will push the bottom of the arc plate through the intermediate shaft, so that the arc plate rotates between the fixed plate 1 and the limit sleeve. At this time, when the arc plate rotates, the curvature of the curved surface of the arc plate will be deflected upward, so that a physical barrier can be formed at the outlet of the air outlet groove, and between the gaps where the air inlet pipe stops rotating, the hot air can be discharged outwards without directly entering the interior of the main body under the influence of wind speed, thereby effectively reducing the situation of hot air reflux.

[0023] 3. In the present invention, when the wave tube 1 drives the convex rod shaft to slide inside the half-toothed cylinder through the wave tube 2, the sliding of the convex rod shaft will squeeze the spring cylinder inside the half-toothed cylinder, and the spring cylinder will push the swing plate to move after being squeezed. When the swing plate is pushed by the spring cylinder, the swing plate will be pulled by the rotating plate. At the same time, when the swing plate slides obliquely, the rectangular groove inside the swing plate will slide obliquely upward on the surface of the rotating plate. At this time, when the swing plate slides obliquely upward, the rectangular groove on its side wall will push the rotating plate The side wall of the plate forms a backward extrusion force on the rotating plate. At this time, under the action of the extrusion force, when the fixed plate slides obliquely upward, the rotating plate will rotate in the opposite direction under the action of the extrusion force in the rectangular groove inside the swing plate. At this time, when the rotating plate rotates, the bottom end of the rotating plate will push the T-shaped rod, so that the T-shaped rod slides inside the intake pipe. When the T-shaped rod slides, it squeezes the gas inside the hollow sleeve. At this time, the gas is squeezed and ejected in a spiral shape through the curved tube. At this time, the one-way cylinder is in a state of being squeezed when the gas is squeezed. In the closed state, the ejected gas will be ejected onto the surface of the elastic plate. At the same time, when the T-shaped rod slides, the front end of the sliding T-shaped rod will slide in the threaded groove inside the fan tube. When the front end of the T-shaped rod slides in the threaded groove inside the fan tube, the fan tube will be driven to rotate inside the air intake pipe through the extrusion force. When the fan tube rotates, the hot air will be adsorbed into the air intake pipe through the opening at the bottom of the limiting sleeve. At the same time, when the fan tube rotates, it will drive the cone tube to rotate. When the gas enters the inside of the air intake pipe, it will pass through the cone. The conical shape of the cylinder allows the conical cylinder to accelerate the flow of gas through the internal spiral structure when it rotates, and impact the elastic plate. At this time, when both sides of the elastic plate are impacted by the gas, the elastic plate will shake. When the elastic plate shakes, the elastic plate will squeeze the gas between the elastic plate and the conical cylinder. After being squeezed, the gas will be ejected outward through the air inlet holes on the surface of the limit sleeve, avoiding the situation where hot air is retained inside the main body when the arc plate rotates upward, which helps to reduce the temperature inside the device and maintain stability.

[0051] A method for using a cabinet back panel passive heat dissipation device, the cabinet back panel passive heat dissipation device, the method comprising the following steps:

[0052] S1: First, the heat-generating electronic component in the main body 1 is closely contacted or brought close to the back of the main body 1. When the electronic component generates heat, the hot air generated by the heat of the electronic component will rise from the back of the main body 1 due to the natural convection principle that hot air rises and cold air falls.

[0053] S2: The cold air flows in from below, forming a natural air circulation flow, wherein when hot air is generated inside the main body 1, it will rise along with the guidance of the guide plate 102;

[0054] S3: When the hot and cold air circulates, the circulation of the air can continuously take away the heat inside the main body 1 and dissipate it into the surrounding environment, thereby reducing the temperature inside the cabinet.

[0055] When in use, first, the heat-generating electronic components in the main body 1 are brought into close contact or proximity with the back side of the main body 1. When the electronic components generate heat, due to the natural convection principle that hot air rises and cold air falls, the hot air generated by the heat generated by the electronic components will rise from the back side of the main body 1, while the cold air will flow in from below, forming a natural air circulation flow. When hot air is generated inside the main body 1, it will rise along with the guidance of the guide plate 102. Later, when the hot and cold air circulate, the circulation of air can continuously take away the heat inside the main body 1 and dissipate it into the surrounding environment, thereby reducing the temperature inside the cabinet.

[0056] When the hot air rises inside the main body 1, the hot air will enter the hollow box 201 through the circular hole at the bottom of the hollow box 201. When the hot air enters the hollow box 201, the airbag 2 301 inside the hollow box 201 will expand due to the heat and contraction. When the hot air accumulates inside the hollow box 201, the airbag 2 301 will expand due to the heat. When the airbag 2 301 expands, it will push the spring plate 2 302 to move inside the hollow box 201. When the spring plate 2 302 moves, the moving spring plate 2 302 will drive the wave tube 1 303, and the wave tube 2 304 will slide with the convex rod shaft 305. When the convex rod shaft 305 slides, it will slide inside the semi-gear cylinder 401. When the spring plate 2 302 slides to the inner wall of the semi-gear cylinder 401, the convex rod shaft 305 will stop sliding. When the cam 305 continues to slide, the waves on the wave tube 303 will squeeze the insertion rod on the surface of the convex rod shaft 305. At this time, the insertion rod will drive the convex rod shaft 305 to rotate along the wave groove on the wave tube 303. When the convex rod shaft 305 rotates, it will drive the fixed disk 402 to rotate through the half-tooth cylinder 401. When the fixed disk 402 rotates, it will drive several curved plates 505 on the side wall of the fixed disk 402 to rotate. When the fixed disk 402 drives several curved plates 505 to rotate, the rotation of the curved plates 505 will break the original static state of the air, promote the mixing and flow of cold and hot air in the main body 1, thereby enhancing the natural convection effect. At the same time, the rotation of the curved plates 505 not only accelerates the flow speed of the air in the main body 1, but also helps to transfer the heat inside the main body 1 to the air faster, and discharge it to the outside of the main body 1 through the air outlet groove 104, thereby improving the overall heat dissipation efficiency.

[0057] When the wave tube 1 303 drives the convex rod shaft 305 to slide inside the half-toothed cylinder 401 through the wave tube 2 304, the sliding of the convex rod shaft 305 will squeeze the spring cylinder 501 inside the half-toothed cylinder 401, and the spring cylinder 501 will push the swing plate 502 to move after being squeezed. When the swing plate 502 is pushed by the spring cylinder 501, the swing plate 502 will be pulled by the rotating plate 503. At the same time, when the swing plate 502 slides obliquely, the rectangular groove inside the swing plate 502 will move obliquely upward on the surface of the rotating plate 503. When the swing plate 502 slides, it will push the bottom of the arc plate 505 through the intermediate shaft 504, so that the arc plate 505 rotates between the fixed plate 402 and the limiting sleeve 404. At this time, when the arc plate 505 rotates, the curvature of the curved surface of the arc plate 505 will be deflected upward, so that a physical barrier can be formed at the outlet of the air outlet groove 104, and between the gaps where the air inlet pipe 403 stops rotating, the hot air is reduced from directly entering the interior of the main body 1 under the influence of wind speed when it is discharged outward, thereby effectively reducing the situation of hot air reflux.

[0058] When the wave tube 1 303 drives the convex rod shaft 305 to slide inside the half-toothed cylinder 401 through the wave tube 2 304, the sliding of the convex rod shaft 305 will squeeze the spring cylinder 501 inside the half-toothed cylinder 401, and the spring cylinder 501 will push the swing plate 502 to move after being squeezed. When the swing plate 502 is pushed by the spring cylinder 501, the swing plate 502 will be pulled by the rotating plate 503. At the same time, when the swing plate 502 slides obliquely, the rectangular groove inside the swing plate 502 will slide obliquely upward on the surface of the rotating plate 503. At this time, when the swing plate 502 slides obliquely upward, it will pass through the rectangular groove on its side wall. The side wall of the rotating plate 503 forms a backward extrusion force on the rotating plate 503. At this time, under the action of the extrusion force, when the rotating plate 503 slides obliquely upward on the fixed plate 402, the rotating plate 503 will rotate in the opposite direction under the action of the extrusion force in the rectangular groove inside the swing plate 502. At this time, when the rotating plate 503 rotates, the bottom end of the rotating plate 503 will push the T-shaped rod 601, so that the T-shaped rod 601 slides inside the air inlet pipe 403. When the T-shaped rod 601 slides, it squeezes the gas inside the hollow sleeve 602. At this time, the gas is squeezed and ejected in a spiral shape through the curved tube 604. At this time, the one-way cylinder 603 is in the air intake pipe 403. When the fan barrel 401 is squeezed, it will be in a closed state. At this time, the ejected gas will be ejected to the surface of the elastic plate 703. At the same time, when the T-shaped rod 601 slides, the front end of the sliding T-shaped rod 601 will slide in the threaded groove inside the fan barrel 701. When the front end of the T-shaped rod 601 slides in the threaded groove inside the fan barrel 701, the fan barrel 701 will be driven to rotate inside the air inlet pipe 403 through the squeezing force. When the fan barrel 701 rotates, the hot air will be adsorbed into the air inlet pipe 403 through the opening at the bottom of the limiting sleeve 404. At the same time, when the fan barrel 701 rotates, it will drive the conical barrel 702 to rotate. When the gas enters the air inlet pipe 403, When the conical cylinder 702 is rotated, the conical shape of the conical cylinder 702 will accelerate the flow of gas through the internal spiral structure when the conical cylinder 702 rotates, and impact the elastic plate 703. At this time, when both sides of the elastic plate 703 are impacted by the gas, the elastic plate 703 will shake. When the elastic plate 703 shakes, the elastic plate 703 will squeeze the gas between the elastic plate 703 and the conical cylinder 702. After being squeezed, the gas will be ejected outward through the air inlet hole on the surface of the limiting sleeve 404, avoiding the situation where hot air is retained inside the main body 1 due to the upward rotation of the arc plate 505, which helps to reduce the temperature inside the device and maintain stability.

[0059] When the spring plate 202 is moved by the expansion of the airbag 201, the bottom plate at the bottom of the airbag 201 will block the circular hole at the bottom of the hollow box 201. Later, when the convex rod shaft 305 drives the half-toothed cylinder 401 to rotate, the teeth on the half-toothed cylinder 401 will drive the toothed plate 206 to move downward. When the toothed plate 206 moves downward, it will drive the spring plate 1 205 to move downward. When the spring plate 1 205 moves downward, it will squeeze the airbag 1 203, so that the gas inside the airbag 1 203 passes through the connecting pipe 202. Since the bottom plate at the bottom of the spring plate 202 blocks the circular hole at the bottom of the hollow box 201, it is difficult for hot air to enter the hollow box 201 at this time. Later, when the gas inside the airbag 1 203 enters the hollow box 201, it will spray onto the surface of the airbag 2 301. At this time, when the airbag 2 301 is subjected to the cooler external temperature, it will shrink, and the device inside the main body 1 will be reset.
