Description

Technical Field

[0001] The present invention relates to the technical field of computer cases, and specifically to a computer case with a recyclable heat dissipation function. Background Art

[0002] At present, with the continuous development of computer technology, computer performance continues to improve, and a large amount of heat is generated during the operation of hardware. There are many drawbacks in the traditional computer case heat dissipation system, which seriously restricts the stable operation and service life of the computer;

[0003] Traditional cases mostly adopt a simple direct blowing heat dissipation method with a fan. Cold and hot air are easily mixed, resulting in the inability to quickly discharge heat. The hardware is in a high-temperature environment for a long time, and the performance drops significantly. For example, when running large software or performing multitasking, the computer is prone to freezing and crashing. At the same time, the internal space layout of traditional cases is messy, and there is no effective distinction between the cold air duct and the hot air duct. The air flow path is chaotic, which not only fails to dissipate heat efficiently but may also cause local overheating and accelerate hardware aging. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: A computer case with a recyclable heat dissipation function, comprising:

[0005] A case body, on the outer surface of which a case door is rotatably installed. On the side of the case body away from the case door, a rear cover plate is fixedly installed. On both sides of the top of the case body, handlebars are fixedly installed. At the four corners of the bottom of the case body, feet are fixedly installed;

[0006] A recyclable heat dissipation mechanism, which is installed in the inner cavity of the case body. The recyclable heat dissipation mechanism separates the external cold air duct from the internal hot air duct to improve the heat dissipation efficiency. An installation rack is fixedly installed inside the recyclable heat dissipation mechanism, and the installation rack is used to install internal computer hardware components;

[0007] Among them, the cyclic heat dissipation mechanism includes a square-shaped partition board. The square-shaped partition board is used to enclose an air passage with the box body. An opening is provided at the corner of one side of the top of the square-shaped partition board. A connecting plate is fixedly installed at the opening of the square-shaped partition board. The connecting plate is fixedly installed on the inner wall of the box body. The connecting plate is used to fix the square-shaped partition board. The outer surface of the square-shaped partition board is fixedly installed with two square-shaped partition pieces. The square-shaped partition pieces are made of heat-insulating materials and are used to separate the cold and hot channels. A hot air guide is installed at the middle of the top of the square-shaped partition board. The hot air guide is used to introduce the hot air generated by the computer case into the hot air duct. Air inlet fans are installed on both sides of the top of the square-shaped partition board. The air inlet fans are used to introduce the cold air in the cold air duct into the interior of the square-shaped partition board to cool the computer hardware components installed on the mounting rack. An air flow adjusting member is installed on the surface of the square-shaped partition piece. The air flow adjusting member is arranged on both sides of the square-shaped partition board. The air flow adjusting member can automatically adjust the width of the air inlet duct according to the wind speed in the cold air duct. The greater the wind speed, the wider the duct.

[0008] Preferably, a chamber is formed between the square-shaped partition board and the inner wall of the box body. The two square-shaped partition pieces divide this chamber into two side chambers and a middle chamber. The side chambers are cold air ducts, and the middle chamber is a hot air duct. The hot air guide is arranged in the middle chamber. The air inlet fans and the air flow adjusting members are both arranged in the side chambers.

[0009] Preferably, an air outlet fan is fixedly installed on one side of the box body. The air outlet fan is arranged below the connecting plate and inside the middle chamber formed by the square-shaped partition board and the box body. The air outlet fan is used to suck out the hot air in the box body to improve the heat dissipation efficiency.

[0010] Preferably, a heat dissipation hole one and a heat dissipation hole two are respectively opened on both sides of the box body. The heat dissipation hole one is arranged below the air outlet fan. A heat dissipation hole three is opened at the middle of the top of the box body. The heat dissipation hole one, the heat dissipation hole two, and the heat dissipation hole three are all arranged outside the middle chamber formed by the square-shaped partition board and the box body. A heat dissipation plate one and a heat dissipation plate two are respectively fixedly installed on both sides of the box body. The heat dissipation plate one and the heat dissipation plate two are respectively arranged outside the heat dissipation hole one and the heat dissipation hole two. A heat dissipation plate three is fixedly installed on the top of the box body. The heat dissipation plate three is arranged directly above the heat dissipation hole three. Heat dissipation fins are fixedly installed on the surfaces of the heat dissipation plate one, the heat dissipation plate two, and the heat dissipation plate three, which are used to absorb the heat generated in the heat dissipation hole one, the heat dissipation hole two, and the heat dissipation hole three and accelerate the heat dissipation speed.

[0011] Preferably, an air inlet hole is opened on one side of the box body. The air inlet hole is arranged on both sides of the heat dissipation hole one. The heat dissipation hole one is arranged outside the side chamber formed by the square-shaped partition board and the box body. The air inlet hole is used to introduce the cold air from the outside.

[0012] Preferably, arc-shaped air guide vane groups are fixedly installed on both sides of the bottom of the inner cavity of the box. The arc-shaped air guide vane group is composed of two arc-shaped air guide vanes. The wider opening of the arc-shaped air guide vane group faces the air inlet hole. The arc-shaped air guide vane group is used to guide the flow of external cold air, so that it can smoothly enter the air inlet fan, improving the utilization efficiency of cold air.

[0013] Preferably, the hot air guide member includes an air inlet pipe and an air outlet pipe. The air inlet pipe is fixedly installed on the inner side surface of the square-shaped partition plate, and the air outlet pipe is fixedly installed on the top of the square-shaped partition plate. The air inlet pipe is communicated with the air outlet pipe. The internal hot air enters the air inlet pipe under the action of the air outlet fan and flows out from the air outlet pipe and is introduced into the hot air duct.

[0014] Preferably, a fixed rotating frame one is fixedly installed at the bottom of the air inlet pipe, and a fixed rotating frame two is fixedly installed at the top of the air outlet pipe. A rotating rod is rotatably installed between the fixed rotating frame one and the fixed rotating frame two. A spiral blade is fixedly installed on the outer surface of the rotating rod. When the hot air flows through the spiral blade, the spiral blade rotates on the surface of the fixed rotating frame two.

[0015] Preferably, the air flow adjusting member includes a fixed rod. The fixed rod is fixedly installed on the surface of the square-shaped spacer. A rotating sleeve is rotatably installed on the outer surface of the fixed rod. A wind blocking piece is fixedly installed on the outer surface of the rotating sleeve. A return spring is fixedly installed on the inner bent surface of the wind blocking piece. The other end of the return spring is fixedly connected to a fixing plate. The fixing plate is fixedly installed on the inner wall of the box. When the cold air flows through the wind blocking piece, the wind blocking piece rotates on the surface of the fixed rod through the rotating sleeve, and the width of the air duct is adjusted by the rotation of the wind blocking piece.

[0016] Preferably, a rotating hole is formed on the outer surface of the rotating sleeve, and a limiting plate is fixedly installed on the outer surface of the fixed rod. The limiting plate is slidably installed inside the rotating hole. The limiting plate is in extrusion fit with the outer bent surface of the wind blocking piece. The limiting plate is arranged below the wind blocking piece, and the limiting plate prevents the wind blocking piece from rotating excessively to block the air duct.

[0017] The present invention provides a computer chassis with a recyclable heat dissipation function. It has the following beneficial effects:

[0018] First, in the computer chassis with a recyclable heat dissipation function, through the arrangement of the square-shaped partition plate and the square-shaped spacer, a chamber is formed between the square-shaped partition plate and the inner wall of the box. The two square-shaped spacers divide it into two side chambers and an intermediate chamber, effectively separating the flow channels of cold and hot air. The external cold air enters the cold air duct of the side chamber from the air inlet hole, and the hot air flows in the hot air duct of the intermediate chamber and is sucked out by the air outlet fan. This design avoids the mixing of cold and hot air, ensures that the cold air can efficiently cool the computer hardware components, the hot air can be quickly discharged, greatly improves the heat dissipation efficiency, provides a suitable temperature environment for the stable operation of the computer hardware, and prolongs the service life of the hardware.

[0019] Second, for the computer case with a recyclable heat dissipation function, through the settings of the intake fan and the exhaust fan, the intake fan is installed on both sides of the top of the mouth-shaped partition, guiding the cold air in the cold air duct into the interior of the mouth-shaped partition to cool the hardware components on the mounting rack, and the exhaust fan is fixed in the middle chamber below the connecting plate on one side of the case body to suck out the hot air. With this setting, a forced convection air cycle is formed inside the case, accelerating the air flow speed inside the case. The cold air continuously enters, and the hot air is quickly discharged, strengthening the heat dissipation effect, effectively reducing the temperature inside the case, and ensuring that the computer can maintain stable performance even under high-load operation.

[0020] Third, for the computer case with a recyclable heat dissipation function, through the setting of the hot air guide component, the internal hot air enters the intake pipe under the action of the exhaust fan, drives the spiral blade to rotate on the surface of the fixed rotating frame two when flowing through the spiral blade, and then flows out from the exhaust pipe and is introduced into the hot air duct. When the spiral blade rotates, it plays a role in pushing the hot air, accelerating the flow speed of the hot air inside the hot air guide component, enabling the hot air to enter the hot air duct and be discharged from the case more quickly, further improving the heat dissipation efficiency and reducing the accumulation of heat inside the case.

[0021] Fourth, for the computer case with a recyclable heat dissipation function, through the setting of the air regulating component, when the cold air flows through the wind deflector, the wind deflector rotates on the surface of the fixed rod through the rotating sleeve, automatically adjusting the width of the intake air duct according to the cold air speed. The greater the speed, the wider the duct. The rotating hole on the outer surface of the rotating sleeve cooperates with the limiting plate on the outer surface of the fixed rod to prevent the wind deflector from rotating excessively, realizing the automatic adjustment of the intake air volume. When the computer hardware is under low load and has little heat generation, a smaller intake air volume can meet the heat dissipation requirements, reducing the fan energy consumption and noise. When the hardware is under high load and the heat generation increases, the air speed increases, and the air regulating component automatically increases the duct width to increase the intake air volume and enhance the heat dissipation effect.

[0022] Fifth, for the computer case with a recyclable heat dissipation function, through the setting of the heat dissipation plate, the heat is dissipated through the heat dissipation holes. The heat dissipation plate is located outside the heat dissipation holes, and the heat dissipation fins on its surface absorb this heat and dissipate it into the surrounding air. The setting of the heat dissipation plate greatly increases the heat dissipation area and speeds up the transfer of heat from the inside of the case to the outside. Using the principle of heat transfer, the heat inside the case is quickly exported, assisting the overall heat dissipation system of the case and further reducing the temperature inside the case to ensure that the computer hardware works under good heat dissipation conditions.

[0038] The rectangular partition 21 and the rectangular spacers 22 prevent the mixing of cold and hot air, ensuring that the cold air can efficiently cool the computer hardware components and the hot air can be quickly discharged, greatly improving the heat dissipation efficiency.

[0039] Second embodiment, on the basis of the first embodiment, please refer to Figures 1 to 6 As shown, an air outlet fan 8 is fixedly installed on one side of the box body 1. The air outlet fan 8 is arranged below the connecting plate 26 and inside the middle chamber enclosed by the rectangular partition 21 and the box body 1. The air outlet fan 8 is used to suck out the hot air in the box body 1 to improve the heat dissipation efficiency;

[0040] On both sides of the box body 1, there are respectively provided a first heat dissipation hole 13 and a second heat dissipation hole 14. The first heat dissipation hole 13 is arranged below the air outlet fan 8. In the middle of the top of the box body 1, there is provided a third heat dissipation hole 15. The first heat dissipation hole 13, the second heat dissipation hole 14 and the third heat dissipation hole 15 are all arranged outside the middle chamber surrounded by the square-shaped partition plate 21 and the box body 1. On both sides of the box body 1, there are respectively fixedly installed a first heat dissipation plate 10 and a second heat dissipation plate 11. The first heat dissipation plate 10 and the second heat dissipation plate 11 are respectively arranged outside the first heat dissipation hole 13 and the second heat dissipation hole 14. On the top of the box body 1, there is fixedly installed a third heat dissipation plate 12. The third heat dissipation plate 12 is arranged directly above the third heat dissipation hole 15.

The first heat dissipation hole 13 is arranged outside the side chamber surrounded by the square-shaped partition plate 21 and the box body 1. The air inlet hole 9 is used to introduce the cold air from the outside;

[0042] On both sides of the bottom of the inner cavity of the box body 1, there are fixedly installed an arc-shaped air guiding vane group 16. The arc-shaped air guiding vane group 16 is composed of two arc-shaped air guiding vanes. The wider opening of the arc-shaped air guiding vane group 16 faces the air inlet hole 9. The arc-shaped air guiding vane group 16 is used to guide the flow of the cold air from the outside, enabling it to smoothly enter the air inlet fan 24 and improving the utilization efficiency of the cold air.

[0043] For the third embodiment, on the basis of the first and second embodiments, please refer to Figures 6 to 9 As shown, the hot air guiding member 23 includes an air inlet pipe 231 and an air outlet pipe 232. The air inlet pipe 231 is fixedly installed on the inner side surface of the square-shaped partition plate 21. The air outlet pipe 232 is fixedly installed on the top of the square-shaped partition plate 21. The air inlet pipe 231 is communicated with the air outlet pipe 232. The internal hot air enters the air inlet pipe 231 under the action of the air outlet fan 8 and flows out from the air outlet pipe 232 and is introduced into the hot air duct;

[0044] At the bottom of the air inlet pipe 231, there is fixedly installed a first fixed rotating frame 233. At the top of the air outlet pipe 232, there is fixedly installed a second fixed rotating frame 234. Between the first fixed rotating frame 233 and the second fixed rotating frame 234, there is a rotating rod 235 rotatably installed. On the outer surface of the rotating rod 235, there is fixedly installed a spiral blade 236. When the hot air flows through the spiral blade 236, the spiral blade 236 rotates on the surface of the second fixed rotating frame 234. When the spiral blade 236 rotates, it plays a pushing role on the hot air, accelerating the flow speed of the hot air in the hot air guiding member 23, enabling the hot air to enter the hot air duct and be discharged from the chassis more quickly, further improving the heat dissipation efficiency and reducing the accumulation of heat in the chassis;

[0045] The air regulating member 25 includes a fixed rod 251 which is fixedly installed on the surface of the square-shaped spacer 22. A rotating sleeve 252 is rotatably installed on the outer surface of the fixed rod 251. A wind deflector 255 is fixedly installed on the outer surface of the rotating sleeve 252. A return spring 256 is fixedly installed on the inner curved surface of the wind deflector 255. The other end of the return spring 256 is fixedly connected to a fixing plate 257 which is fixedly installed on the inner wall of the box body 1. When cold air flows through the wind deflector 255, the wind deflector 255 rotates on the surface of the fixed rod 251 through the rotating sleeve 252, and the width of the air duct is adjusted by the rotation of the wind deflector 255.

[0046] A rotating hole 253 is formed on the outer surface of the rotating sleeve 252. A limiting plate 254 is fixedly installed on the outer surface of the fixed rod 251. The limiting plate 254 is slidably installed inside the rotating hole 253. The limiting plate 254 is in extrusion fit with the outer curved surface of the wind deflector 255. The limiting plate 254 is arranged below the wind deflector 255. The limiting plate 254 prevents the wind deflector 255 from rotating excessively to block the air duct. When the computer hardware is under low load and has little heat generation, a small air intake can meet the heat dissipation requirements, reducing the energy consumption and noise of the fan. When the hardware is under high load and the heat generation increases, the wind speed increases, and the air regulating member 25 automatically increases the width of the air duct to increase the air intake and enhance the heat dissipation effect.

[0047] During use, the intake fan 24 is started to guide the cold air entering the cold air duct into the square-shaped partition 21. The outside cold air enters the chassis through the air intake holes 9. The entering cold air is guided by the arc-shaped air guiding vane group 16 and smoothly flows towards the intake fan 24 to cool the computer hardware components on the mounting rack 3.

[0048] The computer hardware components generate hot air. Under the suction of the exhaust fan 8, the hot air enters the intake pipe 231. The hot air flows through the spiral blades 236 at the bottom of the intake pipe 231, driving the spiral blades 236 to rotate on the surface of the fixed rotating frame two 234 to assist the flow of the hot air.

[0049] The hot air flows out from the exhaust pipe 232 and enters the hot air duct in the middle chamber.

[0050] During the flow of the hot air, the cold air flows through the wind deflector 255 of the air regulating member 25. The wind deflector 255 rotates on the surface of the fixed rod 251 through the rotating sleeve 252, automatically adjusting the width of the intake air duct according to the cold air speed. The rotating hole 253 on the outer surface of the rotating sleeve 252 cooperates with the limiting plate 254 on the outer surface of the fixed rod 251 to prevent the wind deflector 255 from rotating excessively to block the air duct.

[0051] The hot air flows in the hot air duct in the middle chamber and is finally sucked out of the box body 1 by the air outlet fan 8. At the same time, the heat is dissipated through the first heat dissipation hole 13, the second heat dissipation hole 14, and the third heat dissipation hole 15. The heat dissipation fins on the surfaces of the first heat dissipation plate 10, the second heat dissipation plate 11, and the third heat dissipation plate 12 absorb the heat discharged from the heat dissipation holes, accelerating the heat dissipation speed and completing the entire cyclic heat dissipation process.
