At this time, the computer's heat dissipation device is needed to dissipate the heat from the motherboard. Most existing computer cases are provided with air inlets and air outlets when in use, and then the air in the case is circulated with the outside air through a cooling fan. As a result, a large amount of dust will adhere to the air inlet position after long-term use, thereby blocking the air inlet, reducing the air intake and causing the heat dissipation capacity to decrease. At the same time, when a large amount of dust adheres to the air inlet position, some of the dust will enter the case under the action of air suction.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The air flows upward and contacts with the mainboard and other components for heat dissipation and cooling, and then enters the dust removal chamber. The second fan will push the air in the dust removal chamber to flow to the side of the dust discharge slot, so that the air entering the dust removal chamber upward can leave the box through the dust discharge slot, thereby realizing the circulation flow of air in the box and the outside world. The flow of air is guided by the setting of the first guide plate and the second guide plate, so that the flow direction of the air entering the dust removal chamber upward is at an acute angle to the flow direction of the air in the dust removal chamber, which can further accelerate the flow speed of the air and improve the heat dissipation effect of the box. At the same time, the dust removal slot below can be blocked by the second guide plate, so that the air in the dust removal chamber will not flow downward when moving toward the dust discharge slot, avoiding the collision of the two air flow directions to reduce the air flow rate, and at the same time avoiding the dust carried by the air entering the dust removal chamber to fall into the box again, ensuring the cleanliness of the box and the heat dissipation effect of the box.

[0017] 2. When the first piston plate moves to compress the first cavity, the cold air in the first cavity enters the connecting room through the pipe, and then is blown upward through the blowing pipe, thereby dissipating heat and cooling the mainboard above. At the same time, due to the setting of the one-way valve, the first piston plate moves to compress the space of the first cavity so that the gas in the first cavity is discharged under the action of pressure, so that the air blown out of the blowing pipe has a higher speed. At the same time, the high-speed flowing air can blow off the dust attached to the surface of the mainboard, so that the mainboard is cleaned and dust accumulation on the mainboard is avoided, further improving the cooling effect on the mainboard. At the same time, the space of the second cavity is increased, and then the air in the dust removal cavity is sucked into the second cavity through the second connecting pipe, thereby increasing the upward flow speed of the air in the box, further increasing the flow speed of the air in the box, improving the cooling effect, and at the same time, the dust carried in the air can be better extracted into the dust removal cavity, which is beneficial to subsequent dust removal.

[0018] 3. When the first piston plate approaches the end of the sealing chamber, it will contact with the magnet and be adsorbed and fixed. At this time, the first piston plate will push the sliding rod and the sliding plate to move synchronously. The sliding rod drives the second piston plate to move in the gas collecting cylinder, so that the gas in the gas collecting cylinder enters the nozzle through the first connecting pipe, and then is sprayed to the filter hole through the nozzle. The air passes through the filter hole and flows to the outside to realize backwashing of the filter hole, reduce the dust adhesion on the outside of the filter hole, and thus avoid the filter hole from being blocked and reduce the probability of attached dust entering the box body, ensure the air intake, reduce the dust content, and further ensure the heat dissipation effect in the chassis.

[0031] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0033] An air inlet chamber 4 is provided at the bottom of the box body 1, filter holes 5 are provided at both ends of the air inlet chamber 4, a through slot 6 communicating with the air inlet chamber 4 is provided on the bottom surface of the box body 1, a top plate 34 is fixedly installed on the top of the box body 1, the top plate 34 and the top wall of the box body 1 form a dust removal chamber 35, a plurality of groups of dust removal grooves 39 are provided on the top plate 34, a plurality of groups of first guide plates 38 and second guide plates 40 respectively aligned with the side edges of the dust removal grooves 39 are fixedly installed on the top plate 34, the first guide plate 38 and the second guide plate 40 are located on both sides of the top plate 34, the second guide plate 40 is located in the dust removal chamber 35, and the second guide plate 40 projects toward the top plate 34 The shadow covers the adjacent dust removal groove 39, and a dust exhaust groove 37 connected to the dust removal chamber 35 is provided on the side of the box body 1. A baffle 42 is provided in the dust exhaust groove 37, and a mounting groove 41 is provided in the dust exhaust groove 37. The baffle 42 is slidably installed in the mounting groove 41 and closes the dust exhaust groove 37 when the baffle 42 contacts the lower surface of the dust exhaust groove 37. An electromagnet 43 is fixedly installed in the mounting groove 41. When the electromagnet 43 is energized, the baffle 42 is attracted to the baffle, and a magnetic structure adsorbed by the power supply magnet 43 is provided on the upper surface of the baffle 42. A plurality of second fans 36 are fixedly installed on the side of the dust removal chamber 35 away from the dust exhaust groove 37.

[0034] In actual application of this embodiment, the motherboard is fixedly installed on the back plate 25. After the installation is completed, the connection positions on the motherboard and the graphics card will fill the position of the cable connection groove 3, thereby closing the box body 1. After the motherboard is powered on, the first fan 33 and the second fan 36 are turned on synchronously. At the same time, the electromagnet 43 is energized and the baffle 42 is attracted to move upward, thereby opening the dust exhaust groove 37. The outside air enters the air intake chamber 4 after being filtered through the filter hole 5. The air in the air intake chamber 4 moves upward through the through groove 6. At this time, the first fan 33 pushes the air to flow upward. The air flows upward and contacts with the motherboard and other components for heat dissipation and cooling. The air carries the heat and flows upward and enters the dust removal chamber 35 through the dust removal groove 39. The second fan 36 will push the air in the dust removal chamber 35 to the side of the dust removal groove 37, so that the air entering the dust removal chamber 35 upward can leave the box body 1 through the dust removal groove 37, thereby realizing the box body. 1 and the outside world, the air flow is guided by the arrangement of the first guide plate 38 and the second guide plate 40, so that the flow direction of the air entering the dust removal chamber 35 upwards forms an acute angle with the flow direction of the air in the dust removal chamber 35, thereby further accelerating the flow speed of the air and improving the heat dissipation effect of the box body 1. At the same time, the dust removal groove 39 below can be shielded by the second guide plate 40, so that the air in the dust removal chamber 35 will not flow downward when moving toward the dust discharge groove 37, avoiding the collision of the air in the two directions to reduce the air flow rate, and at the same time avoiding the dust carried by the air entering the dust removal chamber 35 to fall into the box body 1 again, ensuring the cleanliness of the box body 1 and the heat dissipation effect of the box body 1. After the main board is powered off, the electromagnet 43 is powered off at this time, and the baffle 42 falls down under the action of gravity to close the dust discharge groove 37, thereby reducing the probability of dust entering the box body 1.

[0035] like Figure 4-Figure 8 As shown, a computer case heat dissipation and cooling device provided by the present invention, a connecting chamber 31 is fixedly installed on the bottom surface of the box body 1, and the connecting chamber 31 is connected to multiple groups of blowing pipes 32 that penetrate the mesh plate 26 upward, and a gap is set between the blowing pipe 32 and the back plate 25. The connecting chamber 31 is connected to the sealing chamber 7 fixedly installed on the bottom surface of the box body 1.

[0036] Specifically, a first piston plate 8 is slidably installed in the sealing chamber 7, and the first piston plate 8 divides the sealing chamber 7 into a first cavity 27 and a second cavity 28. A first reciprocating screw 9 is rotatably installed in the sealing chamber 7 to drive the first piston plate 8 to move back and forth. A rotating power part 10 that drives the first reciprocating screw 9 to rotate is fixedly installed on the bottom surface of the box body 1. The first cavity 27 is connected with the air intake chamber 4 and the connecting chamber 31 through pipelines, and a one-way valve is arranged on the pipeline. The gear set 19 is a bevel gear set, and two groups of bevel gears are arranged. The two groups of bevel gears are fixedly installed on the first rotating shaft 20 and the second reciprocating screw 18, respectively.

[0037] Specifically, the second cavity 28 is connected with a second connecting pipe 29 and a third connecting pipe 30. The ends of the second connecting pipe 29 and the third connecting pipe 30 away from the second cavity 28 extend into the dust removal cavity 35. The end of the second connecting pipe 29 is located in the dust removal cavity 35 at the end away from the dust discharge groove 37. The end of the third connecting pipe 30 is located in the dust removal cavity 35 at the end close to the dust discharge groove 37 and the end of the third connecting pipe 30 points to the dust discharge groove 37. The second connecting pipe 29 and the third connecting pipe 30 are both provided with a one-way valve.

[0038] In actual application of this embodiment, the rotating power member 10 drives the first reciprocating screw rod 9 to rotate, thereby causing the first piston plate 8 to reciprocate in the sealed chamber 7. When the first piston plate 8 moves to compress the first cavity 27, the cold air in the first cavity 27 enters the connecting chamber 31 through the pipeline, and then is blown upward through the blowing pipe 32, thereby dissipating heat and cooling the main board above. At the same time, due to the setting of the one-way valve, the first piston plate 8 moves to compress the space of the first cavity 27, so that the gas in the first cavity 27 is discharged under the action of pressure, so that the air blown out of the blowing pipe 32 has a higher speed, and at the same time, through the high-speed flow The moving air can blow off the dust attached to the surface of the mainboard, thereby cleaning the mainboard and avoiding dust accumulation on the mainboard, further improving the cooling effect on the mainboard. At this time, the space of the second cavity 28 is increased, and the air in the dust removal cavity 35 is sucked into the second cavity 28 through the second connecting pipe 29, thereby increasing the upward flow speed of the air in the box 1, further improving the flow speed of the air in the box 1, and improving the cooling effect. At the same time, the dust carried in the air can be better extracted into the dust removal cavity 35, which is beneficial to subsequent dust removal. A filter is set at the air inlet of the second connecting pipe 29 to reduce the dust from entering the second cavity 28;

[0039] When the first piston plate 8 moves in the opposite direction, the filtered air in the air intake chamber 4 enters the first cavity 27 through the pipe, and the air in the second cavity 28 is ejected through the third connecting pipe 30 under the action of pressure. Since the end of the third connecting pipe 30 points to the dust exhaust groove 37, it can further accelerate the flow of air in the box 1 to the outside, thereby improving the cooling effect and dust removal effect.

[0040] In an embodiment of the present invention, the rotating power member 10 is a motor, and of course it can also be other components capable of outputting rotating power, such as a hydraulic motor, and the first reciprocating screw rod 9 is driven to rotate by the motor.

[0041] like Figure 4-Figure 8 As shown, a computer case heat dissipation cooling device provided by the present invention is provided. Second reciprocating screws 18 are rotatably installed at both ends of the air inlet chamber 4. The second reciprocating screw 18 drives the movable plate 17 to reciprocate. A nozzle 16 is fixedly installed on the movable plate 17. The nozzle 16 faces the direction of the filter hole 5. When the first piston plate 8 moves, it drives the second reciprocating screw 18 to rotate and delivers air to the nozzle 16.

[0042] Specifically, a gas collecting cylinder 12 is fixedly installed on both side walls of the box body 1, a second piston plate 14 is slidably installed in the gas collecting cylinder 12, a sliding rod 11 is fixed on the second piston plate 14, the sliding rod 11 extends into the sealed chamber 7 and is slidably connected to the side wall of the sealed chamber 7, a magnet 24 is fixedly installed on one end of the sliding rod 11 located in the sealed chamber 7, and a magnetic structure for adsorption of the magnet 24 is provided in the corresponding area of ​​the first piston plate 8, a first connecting pipe 15 is connected to the gas collecting cylinder 12, and the first connecting pipe 15 is connected to the nozzle 16.

[0043] Specifically, a slide plate 13 is fixedly mounted on the magnet 24. The slide plate 13 passes through a side wall parallel to the slide rod 11 and through the sealing chamber 7. A rack 23 is fixedly mounted on the end of the slide plate 13. The rack 23 is driven by a ratchet 22 to rotate a second rotating shaft 21 mounted on the bottom surface of the box body 1. The second rotating shaft 21 is rotatably connected to a first rotating shaft 20. The first rotating shaft 20 extends into the air inlet chamber 4 and is rotatably connected to the second reciprocating screw 18 through a gear set 19.

[0044] In actual application of this embodiment, when the first piston plate 8 approaches the end of the sealing chamber 7, it will contact with the magnet 24 and be adsorbed and fixed. At this time, the first piston plate 8 will push the sliding rod 11 and the sliding plate 13 to move synchronously, and the sliding rod 11 drives the second piston plate 14 to move in the gas collecting cylinder 12, so that the gas in the gas collecting cylinder 12 enters the nozzle 16 through the first connecting pipe 15, and then is sprayed to the filter hole 5 through the nozzle 16. The air passes through the filter hole 5 and flows to the outside to realize backwashing of the filter hole 5, thereby reducing the dust adhesion on the outside of the filter hole 5, thereby avoiding the filter hole 5. 5 is blocked and the probability of attached dust entering the box body 1 is reduced, the air intake is guaranteed, the dust content is reduced, and the heat dissipation effect in the box body 1 is further guaranteed. At the same time, the slide plate 13 drives the rack 23 to move, the rack 23 drives the second rotating shaft 21 to rotate through the ratchet 22, the second rotating shaft 21 drives the first rotating shaft 20 to rotate synchronously through the belt, the first rotating shaft 20 drives the second reciprocating screw 18 to rotate through the gear set 19, and then the moving plate 17 drives the nozzle 16 to move horizontally, so that the nozzle 16 cleans the filter holes 5 at different positions;

[0045] When the first piston plate 8 moves in the opposite direction, the first piston plate 8 drives the sliding rod 11 and the sliding plate 13 to move synchronously through the magnet 24. At this time, the second piston plate 14 is reset and draws the air in the air intake chamber 4 into the air collecting cylinder 12, and then cleans it again. When the rack 23 is reset, the ratchet 22 idles, so that the first rotating shaft 20 and the second rotating shaft 21 remain stationary. When the first piston plate 8 moves toward the end of the sealing chamber 7 again, the nozzle 16 will move again, so that the nozzle 16 can spray and move synchronously, ensuring that the outside of the filter hole 5 can be fully cleaned.
