Description

Technical Field

[0001] The invention belongs to the technical field of heat dissipation equipment, and in particular relates to a computer case with multiple heat dissipation mechanisms and a heat dissipation method thereof. Background Art

[0002] Heat dissipation in a computer case is not only a technical requirement, but also the basis for ensuring the healthy operation of the entire system. Electronic components will age faster and increase the failure rate when working at high temperatures. Good heat dissipation can keep the hardware within a safe operating temperature range and extend its service life. When the temperature is too high, core components such as the CPU and GPU may automatically reduce the frequency due to overheating to prevent damage. This will cause performance degradation and may even cause the system to crash or freeze. Effective heat dissipation can help maintain a stable operating frequency and ensure the reliable operation of the system. The importance of heat dissipation in a computer case cannot be ignored. It directly affects the stability, performance, lifespan and user experience of the computer system.

[0003] Traditional computer case heat dissipation usually uses air cooling and water cooling. Both air cooling and water cooling require the case fan to inhale cold air or exhaust hot air to maintain air circulation in the case. In order to improve the heat dissipation efficiency of the case, increasing the ventilation area and ventilation volume in the case is an indispensable measure. However, an excessively large ventilation area will accelerate the accumulation of dust in the case. The accumulation of dust will not only block the heat dissipation channel and hinder air circulation, resulting in reduced heat dissipation efficiency of the case, but may also enter the gaps of electronic components such as the motherboard and graphics card, causing short circuits in tiny circuits on the circuit board, or hardware failures of other hardware. Therefore, a computer case that can ensure heat dissipation efficiency and prevent dust accumulation is needed. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a computer case with multiple heat dissipation mechanisms and a heat dissipation method thereof. The present invention can prevent dust from entering the interior of the case to the greatest extent in a low-power heat dissipation state, and can increase the case volume and the heat dissipation space of the case in a high-power heat dissipation state, and can also increase the ventilation area, greatly improving the heat dissipation efficiency. At the same time, it can also clean the computer ventilation channel, effectively prevent dust from accumulating in the case, ensure the heat dissipation efficiency and ensure the safe operation of the computer.

[0005] The technical solution adopted to solve the above technical problems is: a computer case with multiple heat dissipation mechanisms, including a main frame and a sub-frame, the sub-frame is slidably connected to the main frame, the top of the main frame is rotatably connected to a dust shield, the bottom of the main frame is fixedly connected to an air intake box, and a cleaning mechanism is arranged in the air intake box;

[0006] The mainframe is provided with a front side wall and a rear side wall, and the rear side wall is provided with a first cooling fan;

[0007] The auxiliary machine frame is provided with a left wall and a right wall, the front side of the auxiliary machine frame is provided with a front ash plate, and the rear side of the auxiliary machine frame is provided with a rear ash plate, and the rear ash plate can shield the first cooling fan;

[0008] A plurality of electric push rods are symmetrically fixedly connected to the bottom of the auxiliary machine frame, and the electric push rods can drive the auxiliary machine frame to rise and fall;

[0009] The lifting of the auxiliary frame can drive the cleaning mechanism.

[0010] Through the above technical scheme, when the computer is in a low heat dissipation demand, cold air enters the chassis from the bottom of the air intake box, and then the hot air is discharged through the first cooling fan, which can ensure the normal heat dissipation demand of the computer, and the rear dust shield blocks dust from entering the chassis from the first cooling fan, and the auxiliary frame blocks dust from entering the chassis from the side of the air intake box, thereby minimizing the dust from entering the chassis and effectively ensuring the safe operation of the computer. When the computer is in a high heat dissipation demand, the auxiliary frame rises, the volume of the computer chassis increases, and the heat dissipation efficiency of the computer is effectively improved. When the auxiliary frame rises, the rear dust shield completely exposes the first cooling fan and the side of the air intake box, increasing the air intake and air outlet of the computer chassis, enhancing the air circulation in the computer chassis, and effectively improving the heat dissipation effect. At the same time, the auxiliary frame lifts and drives the cleaning mechanism, which can drive the cleaning mechanism to clean the air intake box, reduce the dust entering the chassis from the air intake box, and effectively ensure the heat dissipation performance of the computer chassis and the stable operation of the computer.

[0011] Preferably, the first cooling fan is fixedly arranged in the chassis, and a filter is arranged on the rear side wall corresponding to the first cooling fan.

[0014] Through the above technical scheme, since a plurality of ventilation holes are equidistantly arranged on the rear dust shield, a plurality of scrapers are equidistantly fixedly arranged on the front side of the rear dust shield, and the scrapers and the ventilation holes are staggered, when the rear dust shield blocks the first cooling fan, the hot air exhausted by the first cooling fan can be discharged through the ventilation holes, and when the rear dust shield is raised or lowered with the auxiliary frame, the scraper can scrape and clean the filter, effectively preventing dust from accumulating on the filter and hindering the exhaust efficiency of the first cooling fan.

[0015] Preferably, a second cooling fan is fixedly connected to the top of the auxiliary frame, a gap is provided between the second cooling fan and the dust shielding plate, and the auxiliary frame can be lifted to open the dust shielding plate.

[0016] Through the above technical solution, since the second cooling fan is fixedly connected to the top of the sub-frame, a gap is set between the second cooling fan and the dust shielding plate, the sub-frame can be raised to push the dust shielding plate open, so that the hot air in the chassis can be discharged from the chassis not only through the first cooling fan, but also through the second cooling fan. Under normal conditions, the hot air exhausted by the second cooling fan is discharged through the gap between the second cooling fan and the dust shielding plate. The dust shielding plate can effectively prevent dust from entering the chassis from the second cooling fan. After the sub-frame is raised, the dust shielding plate is opened, which can effectively increase the exhaust volume of the second cooling fan.

[0017] Preferably, air holes are symmetrically arranged at the bottom and sides of the air intake box, an air intake fan is fixedly connected to the top of the air intake box, and a first bracket and a second bracket are fixedly connected in the middle of the air intake box.

[0018] Through the above technical solution, since air holes are symmetrically arranged on the bottom and sides of the air intake box, an air intake fan is fixedly connected to the top of the air intake box, so that cold air can enter the chassis from the air holes on the air intake box, and the setting of the air intake fan can suck cold air into the chassis.

[0019] Preferably, the cleaning mechanism includes a cleaning scraper, a threaded rod, a first transmission rod, a second transmission rod and a transmission chain, the cleaning scraper is two groups symmetrically slidably connected in the air intake box, the threaded rod is rotatably connected to the first bracket, the first transmission rod is rotatably connected to the second bracket, the top of the intake fan is fixedly connected to a third bracket, and the second transmission rod is rotatably connected to the third bracket.

[0020] Through the above technical solution, since the cleaning scrapers are two groups symmetrically slidably connected in the air intake box, when the cleaning scrapers slide in the air intake box, they can scrape and clean the air holes on the bottom and sides of the air intake box, effectively preventing dust from accumulating on the air intake box and blocking the air intake channel on the air intake box, thereby ensuring the heat dissipation performance of the chassis.

[0021] Preferably, the threaded rod passes through the cleaning scraper, the cleaning scraper is threadedly connected to the threaded rod, a first bevel gear is fixedly connected to the threaded rod, one end of the first transmission rod is fixedly connected to the second bevel gear, the other end of the first transmission rod is fixedly connected to the first transmission wheel, one end of the second transmission rod is fixedly connected to the second transmission wheel, the other end of the second transmission rod is fixedly connected to the driven gear, the first transmission wheel is connected to the second transmission wheel through a transmission chain, a driving rack is fixedly connected to the inner wall of the sub-frame, the driving rack is meshed with the driven gear, and the first bevel gear is meshed with the second bevel gear.

[0022] The transmission gear of the present invention is a gear which is engaged with the first and second gears and is engaged with the first and second gears of the first gear.

[0023] Preferably, a plurality of dust collecting grooves are symmetrically arranged at the bottom of the air intake box, and the auxiliary frame can cover the air holes on the side of the air intake box.

[0024] Through the above technical solution, since a plurality of dust collecting grooves are symmetrically arranged at the bottom of the air inlet box, the auxiliary frame can cover the air holes on the side of the air inlet box, so that when the cleaning scraper scrapes and cleans the air inlet box, the dust can be pushed into the dust collecting groove, and the dust collecting groove is provided with a cleaning hole on the side, and the dust can be sucked out by a dust suction device, so that the air inlet box can be cleaned without disassembling the chassis, which effectively simplifies the difficulty of cleaning operation;

[0025] When the sub-frame is lowered, it can cover the air holes on the side of the air intake box, which can greatly reduce the dust entering the chassis through the air intake box, effectively ensuring the stable operation of the computer. When the sub-frame is raised, the side of the air intake box is exposed, which effectively increases the air intake area of ​​the air intake box, increases the air intake volume, and ensures improved heat dissipation efficiency.

[0026] A computer case heat dissipation method comprises the following steps:

[0027] Step 1: When the computer is in a low-intensity heat dissipation demand state such as just starting up, it is normally turned on and used, and the intake fan, the first cooling fan and the second cooling fan work at low power. The intake fan introduces cold air into the chassis through the air permeability at the bottom of the air intake box, the first cooling fan exhausts the hot air through the filter and the ventilation holes on the rear dust shield, and the second cooling fan exhausts the hot air through the gap between the second cooling fan and the dust shield;

[0028] Step 2. When the computer is in a state of high-intensity heat dissipation demand, the intake fan, the first cooling fan and the second cooling fan work at high power, the electric push rod is started to lift the auxiliary frame, the auxiliary frame pushes open the dust cover on the top of the main frame, and the rear dust cover rises with the auxiliary frame to completely expose the filter, and as the auxiliary frame rises, the air vents on the side of the air intake box are also completely exposed. At this time, the air intake area of ​​the air intake box is increased and the power of the intake fan is increased, the air intake volume in the chassis is greatly increased, and the air outlets of the first cooling fan and the second cooling fan are unblocked, and the first cooling fan and the second cooling fan are running at high power, the exhaust volume of the chassis is also greatly increased, so that the heat dissipation efficiency of the computer is improved, and the high-intensity heat dissipation demand of the computer is effectively met.

[0029] Step 3: During the lifting and lowering of the auxiliary frame, the scraper on the rear dust plate can scrape and clean the filter. As the auxiliary frame is lifted and lowered, the driving rack can drive the cleaning scraper on the cleaning mechanism to slide horizontally in the air inlet box to scrape and clean the air inlet box, effectively ensuring the smoothness of the air inlet and outlet channels of the chassis, preventing dust from clogging the channels and affecting the heat dissipation efficiency. Not only can it be cleaned during normal operation, but the auxiliary frame can also be lifted and lowered repeatedly regularly for key cleaning, without manual cleaning, simplifying the difficulty of cleaning operations;

[0030] Step 4: The second cooling fan on the top of the sub-frame is detachable, which not only facilitates the cleaning and maintenance of the second cooling fan, but also allows the second cooling fan to be replaced with a water-cooled cooling fan, so that the chassis has multiple heat dissipation methods and improves the heat dissipation efficiency of the chassis.

[0031] The beneficial effects of the present invention are as follows:

[0032] (1) In the present invention, the rear dust shield shields the first cooling fan, which can effectively prevent dust from entering the chassis from the first cooling fan. The dust shield can effectively prevent dust from entering the chassis from the second cooling fan. When the auxiliary frame is in the lowered state, it can shield the air holes on the side of the air intake box, which can greatly reduce the dust from entering the chassis through the air intake box. Multiple measures are taken to prevent dust from entering the chassis, thereby ensuring the safe operation of the computer to the greatest extent and prolonging the service life of the computer.

[0033] (2) When the computer in the present invention is in a high heat dissipation demand, the sub-frame rises, the volume of the computer case increases, and the heat dissipation space of the computer is increased, which can effectively improve the heat dissipation efficiency of the computer. When the sub-frame rises, the sub-frame pushes open the dust shield on the top of the main frame, and the second heat dissipation fan is completely exposed. The rear dust shield is raised with the sub-frame to completely expose the filter, that is, the first heat dissipation fan is completely exposed. As the sub-frame rises, the air holes on the side of the air inlet box are also completely exposed, which effectively increases the air intake and air outlet of the computer case, enhances the air circulation in the computer case, and effectively improves the heat dissipation effect.

[0034] (3) In the present invention, the driving rack can drive the driven gear to rotate as the sub-frame rises and falls, thereby driving the cleaning scraper to slide horizontally in the air inlet box. When the cleaning scraper slides in the air inlet box, the air holes on the bottom and sides of the air inlet box can be scraped and cleaned. When the cleaning scraper scrapes and cleans the air inlet box, the dust can be pushed into the dust collecting trough, which effectively prevents dust from being deposited on the air inlet box and blocking the air inlet channel on the air inlet box, thereby ensuring the heat dissipation performance of the chassis.

[0051] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0052] like Figure 1 - Figure 6 As shown, a computer case with multiple heat dissipation mechanisms includes a main frame 1 and a sub-frame 2, the sub-frame 2 is slidably connected to the main frame 1, a dust shield 3 is rotatably connected to the top of the main frame 1, an air inlet box 4 is fixedly connected to the bottom of the main frame 1, and a cleaning mechanism 5 is arranged in the air inlet box 4.

[0053] The host frame 1 is provided with a front side wall and a rear side wall, and a first heat dissipation fan 11 is provided on the rear side wall.

[0054] The auxiliary frame 2 is provided with a left wall and a right wall. A front dust shield 24 is provided at the front side of the auxiliary frame 2 , and a rear dust shield 23 is provided at the rear side of the auxiliary frame 2 . The rear dust shield 23 can shield the first cooling fan 11 .

[0055] A plurality of electric push rods 21 are symmetrically fixedly connected to the bottom of the auxiliary machine frame 2 , and the electric push rods 21 can drive the auxiliary machine frame 2 to rise and fall.

[0056] The cleaning mechanism 5 can be driven by the lifting and lowering of the sub-frame 2 .

[0057] In this embodiment, when the computer is in a low heat dissipation demand, cold air enters the chassis from the bottom of the air inlet box 4, and then the hot air is discharged through the first cooling fan 11, which can ensure the normal heat dissipation demand of the computer, and the rear dust baffle 23 blocks dust from entering the chassis from the first cooling fan 11, and the sub-frame 2 blocks dust from entering the chassis from the side of the air inlet box 4, thereby minimizing the entry of dust into the chassis and effectively ensuring the safe operation of the computer. When the computer is in a high heat dissipation demand, the sub-frame 2 rises, the volume of the computer chassis increases, and the heat dissipation efficiency of the computer is effectively improved. When the sub-frame 2 rises, the rear dust baffle 23 completely exposes the first cooling fan 11, and at the same time exposes the side of the air inlet box 4, increasing the air intake and outlet volume of the computer chassis, enhancing the air circulation in the computer chassis, and effectively improving the heat dissipation effect. At the same time, the sub-frame 2 lifts and drives the cleaning mechanism 5, which can drive the cleaning mechanism 5 to clean the air inlet box 4, reduce the dust entering the chassis from the air inlet box 4, and effectively ensure the heat dissipation performance of the computer chassis and the stable operation of the computer.

[0058] like Figure 5 - Fig.10 As shown, the first cooling fan 11 is fixedly arranged in the chassis, and a filter screen 111 is arranged on the rear side wall corresponding to the first cooling fan 11 .

[0059] A plurality of ventilation holes 231 are equidistantly arranged on the rear ash baffle 23 , and a plurality of scrapers 232 are equidistantly fixedly arranged on the front side of the rear ash baffle 23 . The scrapers 232 and the ventilation holes 231 are arranged alternately.

[0060] In this embodiment, due to the setting of the filter 111 and the rear dust shield 23 to block the first cooling fan 11, dust can be effectively blocked from entering the chassis from the first cooling fan 11. When the rear dust shield 23 blocks the first cooling fan 11, the hot air exhausted by the first cooling fan 11 can be discharged through the ventilation hole 231. When the rear dust shield 23 is raised or lowered with the sub-frame 2, the scraper 232 can scrape and clean the filter 111, effectively preventing dust from accumulating on the filter 111 and hindering the exhaust efficiency of the first cooling fan 11.

[0061] like Figure 1 - Figure 4 As shown, a second cooling fan 22 is fixedly connected to the top of the auxiliary frame 2, and a gap is provided between the second cooling fan 22 and the dust shielding plate 3, so that the auxiliary frame 2 can be lifted to open the dust shielding plate 3.

[0062] In this embodiment, the hot air in the chassis can be discharged from the chassis not only through the first cooling fan 11, but also through the second cooling fan 22. Under normal conditions, the hot air exhausted by the second cooling fan 22 is discharged through the gap between the second cooling fan 22 and the dust shielding plate 3. The dust shielding plate 3 can effectively prevent dust from entering the chassis from the second cooling fan 22. After the sub-frame 2 is raised, the dust shielding plate 3 is opened, which can effectively increase the exhaust volume of the second cooling fan 22.

[0063] like Fig.11 - Fig.15 As shown, the air inlet box 4 is symmetrically provided with air holes at the bottom and sides, an air inlet fan 44 is fixedly connected to the top of the air inlet box 4, and a first bracket 41 and a second bracket 42 are fixedly connected to the middle of the air inlet box 4;

[0064] The cleaning mechanism 5 includes a cleaning scraper 51, a threaded rod 52, a first transmission rod 53, a second transmission rod 54 and a transmission chain 55. The cleaning scrapers 51 are two groups symmetrically slidably connected in the air inlet box 4. The threaded rod 52 is rotatably connected to the first bracket 41. The first transmission rod 53 is rotatably connected to the second bracket 42. The top of the air inlet fan 44 is fixedly connected to the third bracket 441. The second transmission rod 54 is rotatably connected to the third bracket 441.

[0065] The threaded rod 52 penetrates the cleaning scraper 51, and the cleaning scraper 51 is threadedly connected to the threaded rod 52. A first bevel gear 521 is fixedly connected to the threaded rod 52. One end of the first transmission rod 53 is fixedly connected to the second bevel gear 531, and the other end of the first transmission rod 53 is fixedly connected to the first transmission wheel 532. One end of the second transmission rod 54 is fixedly connected to the second transmission wheel 542, and the other end of the second transmission rod 54 is fixedly connected to the driven gear 541. The first transmission wheel 532 is connected to the second transmission wheel 542 through a transmission chain 55. A driving rack 25 is fixedly connected to the inner wall of the auxiliary frame 2, and the driving rack 25 is meshed with the driven gear 541. The first bevel gear 521 is meshed with the second bevel gear 531.

[0066] A plurality of dust collecting grooves 43 are symmetrically arranged at the bottom of the air inlet box 4 , and the auxiliary machine frame 2 can cover the air holes on the side of the air inlet box 4 .

[0067] In this embodiment, when the sub-frame 2 is lowered, the air holes on the side of the air inlet box 4 can be blocked, which can greatly reduce the dust from entering the chassis through the air inlet box 4, effectively ensuring the stable operation of the computer. When the sub-frame 2 is raised, the side of the air inlet box 4 is exposed, effectively increasing the air inlet area of ​​the air inlet box 4, increasing the air intake volume, and ensuring the improvement of heat dissipation efficiency.

[0068] When the driving rack 25 is lifted or lowered along with the auxiliary frame 2, the driven gear 541 can be driven to rotate, the driven gear 541 can be driven to rotate, the second transmission rod 54 can be driven to rotate, the second transmission rod 54 can be driven to rotate, the second transmission wheel 542 can be driven to rotate, the second transmission wheel 542 can be driven to rotate, the first transmission wheel 532 can be driven to rotate, the first transmission rod 53 can be driven to rotate, the first transmission rod 53 can be driven to rotate, the second bevel gear 531 can be driven to rotate, the first bevel gear 521 can be driven to rotate, the first bevel gear 521 can be driven to rotate the threaded rod 52, the threaded rod 52 can be driven to slide the cleaning scraper 51 horizontally in the air inlet box 4;

[0069] When the cleaning scraper 51 slides in the air intake box 4, the air holes on the bottom and sides of the air intake box 4 can be scraped and cleaned. When the cleaning scraper 51 scrapes and cleans the air intake box 4, the dust can be pushed into the dust collecting groove 43, which effectively prevents the dust from being deposited on the air intake box 4 and blocking the air intake channel on the air intake box 4, thereby ensuring the heat dissipation performance of the chassis.

[0070] A computer case heat dissipation method comprises the following steps:

[0071] Step 1: When the computer is in a low-intensity heat dissipation demand state such as just starting up, it is normally started up and used, and the air intake fan 44, the first heat dissipation fan 11 and the second heat dissipation fan 22 work at low power. The air intake fan 44 introduces cold air into the chassis through the ventilation at the bottom of the air intake box 4, and the first heat dissipation fan 11 exhausts the hot air through the filter 111 and the ventilation holes 231 on the rear dust shield 23. The second heat dissipation fan 22 exhausts the hot air through the gap between the second heat dissipation fan 22 and the dust shield 3;

[0072] Step 2: When the computer is in a state of high-intensity heat dissipation demand, the air intake fan 44, the first heat dissipation fan 11 and the second heat dissipation fan 22 work at high power, the electric push rod 21 is started to lift the auxiliary frame 2, and the auxiliary frame 2 pushes open the dust shield 3 on the top of the main frame 1, and the rear dust shield 23 is lifted up with the auxiliary frame 2 to completely expose the filter 111, and as the auxiliary frame 2 is lifted up, the air vents on the side of the air intake box 4 are also completely exposed. At this time, the air intake area of ​​the air intake box 4 is increased and the power of the air intake fan 44 is increased, the air intake volume in the chassis is greatly increased, and the air outlets of the first heat dissipation fan 11 and the second heat dissipation fan 22 are not blocked, and the first heat dissipation fan 11 and the second heat dissipation fan 22 are running at high power, the exhaust volume of the chassis is also greatly increased, so that the heat dissipation efficiency of the computer is improved, and the high-intensity heat dissipation demand of the computer is effectively met;

[0073] Step 3: During the lifting and lowering process of the auxiliary frame 2, the scraper 232 on the rear dust plate 23 can scrape and clean the filter screen 111. As the driving rack 25 of the auxiliary frame 2 is lifted and lowered, the cleaning scraper 51 on the cleaning mechanism 5 can be driven to slide horizontally in the air inlet box 4 to scrape and clean the air inlet box 4, effectively ensuring the smoothness of the air inlet and outlet channels of the chassis, preventing dust from clogging the channels and affecting the heat dissipation efficiency. Not only can the cleaning be performed during normal operation, but the auxiliary frame 2 can also be lifted and lowered reciprocatingly for multiple times regularly for key cleaning, without manual cleaning, simplifying the difficulty of cleaning operation;

[0074] Step 4: The second cooling fan 22 on the top of the auxiliary frame 2 is detachable, which not only facilitates the cleaning and maintenance of the second cooling fan 22, but also allows the second cooling fan 22 to be replaced with a water-cooled cooling fan, so that the chassis has multiple heat dissipation methods and improves the heat dissipation efficiency of the chassis.

[0075] Working principle:

[0076] When working, the computer has different requirements for heat dissipation in different working states. When the heat dissipation requirement is low, the intake fan 44, the first cooling fan 11 and the second cooling fan 22 work at low power. The intake fan 44 introduces cold air into the chassis through the ventilation at the bottom of the air inlet box 4. The first cooling fan 11 exhausts the hot air through the filter 111 and the ventilation holes 231 on the rear dust shield 23. The second cooling fan 22 exhausts the hot air through the gap between the second cooling fan 22 and the dust shield 3. The hot air in the chassis can be discharged from the chassis not only through the first cooling fan 11, but also through the second cooling fan 22, thereby ensuring the normal heat dissipation requirements of the computer.

[0077] At this time, the rear dust shield 23 blocks the first cooling fan 11, which can effectively prevent dust from entering the chassis from the first cooling fan 11. The dust shield 3 can effectively prevent dust from entering the chassis from the second cooling fan 22. The sub-frame 2 can block the air holes on the side of the air intake box 4 when in the lowered state, which can greatly reduce the dust from entering the chassis through the air intake box 4. Multiple measures are taken to prevent dust from entering the chassis, effectively ensuring the safe operation of the computer.

[0078] When the computer is in high heat dissipation demand, the intake fan 44, the first cooling fan 11 and the second cooling fan 22 work at high power, the electric push rod 21 is started to lift the sub-frame 2, and the sub-frame 2 pushes open the dust shield 3 on the top of the main frame 1, and the second cooling fan 22 is completely exposed. The rear dust shield 23 is lifted up with the sub-frame 2 to completely expose the filter 111, that is, the first cooling fan 11 is completely exposed, and as the sub-frame 2 is lifted up, the air holes on the side of the air intake box 4 are also completely exposed, which effectively increases the air intake and air outlet of the computer case, enhances the air circulation in the computer case, and effectively improves the heat dissipation effect.

[0079] At the same time, the volume of the computer case is increased, and the heat dissipation space inside the computer case is increased, which can effectively improve the heat dissipation efficiency of the computer.

[0080] When the driving rack 25 rises with the auxiliary frame 2, it can drive the driven gear 541 to rotate, the driven gear 541 can drive the second transmission rod 54 to rotate, the second transmission rod 54 can drive the second transmission wheel 542 to rotate, the second transmission wheel 542 can drive the first transmission wheel 532 to rotate, the first transmission wheel 532 can drive the first transmission rod 53 to rotate, the first transmission rod 53 can drive the second bevel gear 531 to rotate, the second bevel gear 531 can drive the first bevel gear 521 to rotate, the first bevel gear 521 can drive the threaded rod 52 to rotate, and the threaded rod 52 can drive the cleaning scraper 51 to slide horizontally in the air inlet box 4.

[0081] When the cleaning scraper 51 slides in the air intake box 4, the air holes on the bottom and sides of the air intake box 4 can be scraped and cleaned. When the cleaning scraper 51 scrapes and cleans the air intake box 4, the dust can be pushed into the dust collecting groove 43, which effectively prevents the dust from being deposited on the air intake box 4 and blocking the air intake channel on the air intake box 4, thereby ensuring the heat dissipation performance of the chassis.

[0082] After the computer is used, the electric push rod 21 is started to lower the auxiliary frame 2. At this time, the rear dust shield 23 is reset to block the first cooling fan 11, and the dust shield 3 is closed to block the second cooling fan 22. The auxiliary frame 2 can block the air holes on the side of the air intake box 4 when it is lowered. At the same time, the driving rack 25 can drive the driven gear 541 to rotate in the opposite direction as the auxiliary frame 2 descends, and finally drives the cleaning scraper 51 to slide horizontally in the opposite direction in the air intake box 4 to clean the air intake box 4 again. When the chassis needs to be cleaned in detail, the auxiliary frame 2 can be raised and lowered multiple times.

[0083] A cleaning hole is provided on the side of the dust collecting groove 43, and dust can be sucked out by a vacuuming device, so that the air intake box 4 can be cleaned without disassembling the chassis, which effectively simplifies the difficulty of cleaning operation. The second cooling fan 22 on the top of the sub-frame 2 is detachable, and the second cooling fan 22 can be easily cleaned without disassembling the chassis, which further simplifies the difficulty of cleaning operation. The second cooling fan 22 can also be replaced with a water-cooled cooling fan, so that the chassis has multiple heat dissipation methods, thereby improving the heat dissipation efficiency of the chassis.

[0084] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.

The air intake fan (44) introduces cold air into the chassis through the air permeability at the bottom of the air intake box (4), the first heat dissipation fan (11) discharges hot air through the filter (111) and the ventilation holes (231) on the rear dust shield (23), and the second heat dissipation fan (22) discharges hot air through the gap between the second heat dissipation fan (22) and the dust shield (3); Step 2: When the computer is in a state of high-intensity heat dissipation demand, the air intake fan (44), the first heat dissipation fan (11) and the second heat dissipation fan (22) work at high power, the electric push rod (21) is started to lift the auxiliary frame (2), the auxiliary frame (2) pushes open the dust cover (3) on the top of the main frame (1), and the rear dust cover (23) rises with the auxiliary frame (2) to completely expose the filter (111), and as the auxiliary frame (2) rises, the air vents on the side of the air intake box (4) are also completely exposed.
