Description

Technical Field

[0002] A computer, commonly known as a PC, is a modern electronic computing machine used for high-speed calculations. It can perform numerical calculations, logical calculations, and has storage and memory functions. It is a modern intelligent electronic device that can run according to a program and automatically and quickly process massive amounts of data. The host refers to the main body of the computer excluding input and output devices. It is also the control box used to house the motherboard and other major components.

[0003] Most computer cases on the market are made of hard materials such as cold-rolled steel or aluminum alloy to protect the internal components. These computer cases usually have a lot of ventilation holes on the outside. With the help of cooling fans, the heat on the surface of the internal components is blown away to complete the heat exchange and protect the computer. However, existing computer cases on the market rely entirely on internal water cooling radiators or cooling fans to dissipate heat from the internal components. Apart from mounting slots and ventilation holes, the cases themselves lack other effective heat dissipation structures.

[0015] 2. This circulating high-heat-dissipation computer chassis uses an air pump to pump air into the first hose and airbag, immersing the airbag in cooling water to lower the temperature of the air inside the airbag. The air inside the airbag, which is lower than the internal temperature of the main chassis and the secondary chassis, is then delivered to the extension pipe through the second hose and blown into the interior of the main chassis through the exhaust vents and ventilation plates. This increases the air exhaust speed from the main chassis and the secondary chassis while improving the heat exchange efficiency. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1:

[0020] Please see Figure 1-11 A circulating high-heat-dissipation computer host chassis includes a host chassis 1. A bolt and nut assembly 11 is fixed to one side of the host chassis 1. A sub-chassis 2 is slidably connected inside the host chassis 1. A frame 23 is fixed to one side of the sub-chassis 2. A limit frame 24 is fixed to the side of the frame 23 near the bolt and nut assembly 11. The limit frame 24 is slidably connected to the bolt and nut assembly 11. An inspection window 25 is opened on the side of the sub-chassis 2 away from the limit frame 24. A limit frame 26 is fixed to the inner wall of the sub-chassis 2 near the inspection window 25. A sliding plate 27 is slidably connected inside the limit frame 26. A protective shell 3 is fixed to the side of the frame 23 near the main unit 1. A circulating water pipe 31 is fixed inside the protective shell 3. A heat dissipation fin 32 is fixed to the surface of the circulating water pipe 31. A water pump 33 is fixed to the top of the protective shell 3. One end of the circulating water pipe 31 is fixed to the water inlet end of the water pump 33. The other end of the circulating water pipe 31 is fixed to the water outlet tee pipe 34. The water outlet end of the water pump 33 is fixed to the water inlet tee pipe 341. A water box 35 is fixed to one end of both the water outlet tee pipe 34 and the water inlet tee pipe 341. A copper sheet 36 is fixed to the surface of the water box 35. A connecting pipe 37 is fixed to the side of the protective shell 3 near the inspection window 25. An air duct 38 is fixed to one end of the connecting pipe 37. An air guide groove 39 is opened inside the air duct 38. A mounting shell 4 is fixed to the surface of the protective shell 3. A motor 41 is fixed inside the mounting shell 4. A fan blade 42 is fixed to the surface of the motor 41. An external ventilation hole 12 is opened on the side of the main unit box 1 near the bolt and nut assembly 11. A mounting bracket 13 is fixed inside the main unit box 1. A pad 14 is fixed to the bottom of the main unit box 1. A limit rod 21 is fixed on one side of the auxiliary chassis 2, and a docking rod 22 is fixed on the inner wall of the main chassis 1. The limit rod 21 and the docking rod 22 are slidably connected. An internal ventilation hole 201 is opened on the side of the auxiliary chassis 2 near the limit frame 24. There are two water boxes 35. A buckle 351 is fixed on the top of the water box 35. The water outlet tee pipe 34 and the water inlet tee pipe 341 are connected to the two water boxes 35. The buckle 351 is snapped onto the surface of the horizontal part of the mounting bracket 13. There are two sliding plates 27. A magnetic block 28 is fixed on the surface of the two sliding plates 27 that are close to each other. The two magnetic blocks 28 attract each other. Specifically, in actual operation, first rotate the nuts on the surface of the bolt and nut assembly 11 to release the nuts from limiting the limit frame 24 and the bolt and nut assembly 11. Then pull the frame 23 outward, so that the frame 23 drives the secondary chassis 2 to be pulled out from the inside of the main chassis 1. At the same time, the secondary chassis 2 drives the limit rod 21 to be pulled out from the inside of the docking rod 22, thereby opening the main chassis 1. At this time, the internal components of the computer can be installed inside the main chassis 1 and on the surface of the mounting bracket 13. After the internal components are installed, the limiting rod 21 is inserted into the connecting rod 22, and the auxiliary housing 2 is inserted into the main housing 1. The limiting bracket 24 is sleeved on the outside of the bolt in the bolt and nut assembly 11. Then, according to the reserved space, the position of the auxiliary housing 2 inside the main housing 1 is adjusted, so that the auxiliary housing 2 drives the limiting bracket 24 to slide on the outside of the bolt and nut assembly 11. When the distance between the main housing 1 and the auxiliary housing 2 is adjusted to a suitable distance, the nuts on the surface of the bolt and nut assembly 11 are rotated to fix and lock the main housing 1 and the auxiliary housing 2. Thus, the present invention can adjust the overall width of the main unit according to the current placement space. By adjusting the width of the main unit, the airflow inside the main unit chassis 1 and the secondary chassis 2 is increased, so that the air inside the main unit chassis 1 and the secondary chassis 2 can be exchanged with the outside air more quickly under the action of the external ventilation holes 12 and the internal ventilation holes 201, thereby improving the heat dissipation effect on the internal components installed inside the main unit chassis 1. Meanwhile, the adjustment of the distance between the main unit chassis 1 and the auxiliary unit chassis 2 increases the installation space inside the main unit chassis 1, thereby increasing the gap between the internal components. This allows the heat around the internal components to exchange heat with the surrounding air more quickly, further improving the heat dissipation effect of the present invention.

[0021] Furthermore, after the internal components are installed, the two water boxes 35 can be snapped onto the bottom of the two mounting brackets 13 using the buckle 351, so that the water box 35 drives the copper sheet 36 to be installed at the bottom of the horizontal part of the mounting bracket 13 and fits against the mounting bracket 13, so that the heat of the internal components installed on the surface of the mounting bracket 13 can be transferred to the mounting bracket 13 first, and then transferred to the copper sheet 36 through the mounting bracket 13. The water tank 35 contains cooling oil. When the computer starts, the water pump 33 can be started through the computer motherboard. The hot cooling oil in the water tank 35 is pumped into the circulating water pipe 31 through the water pump 33 and the inlet tee pipe 341, and then pumped back into the water tank 35 through the water pump 33 and the inlet tee pipe 341 to form a circulation. During the circulation, the temperature of the hot cooling oil gradually decreases. At the same time, under the action of the heat dissipation fins 32, water cooling circulation is formed to dissipate heat and further transfer heat to the outside. Then, the motherboard drives the motor 41 to start, which in turn drives the fan blades 42 to blow air into the interior of the protective shell 3, blowing away the heat from the surface of the heat sink fins 32. This provides additional water cooling for the components inside the main unit 1, further improving the heat dissipation performance of the invention.

[0022] Furthermore, when the internal parts of the main unit chassis 1 and the secondary unit chassis 2 need to be inspected during subsequent use of this invention, the two magnetic blocks 28 can be moved to separate them, causing the sliding plate 27 to slide inside the limiting frame 26, thereby opening the inspection window 25. At this time, the user can observe the internal condition of the main unit chassis 1 and the secondary unit chassis 2, which is convenient for maintenance and inspection. This makes it possible for this invention to be used without having to be completely disassembled like a traditional main unit chassis before inspection and maintenance, thus improving the convenience of using this invention. Meanwhile, small holes are provided on the surface of the sliding plate 27. These holes can further increase the speed of air circulation from the main unit chassis 1 and the auxiliary chassis 2 to the outside, thereby further improving the heat dissipation performance inside the main unit chassis 1 and the auxiliary chassis 2. At the same time, the air blown into the main unit chassis 1 and the auxiliary chassis 2 by the mounting shell 4 can carry the heat from the surface of the heat dissipation fins 32 and the circulating water pipe 31 into the interior of the connecting pipe 37 and the air duct 38, and blow it directly into the small holes on the surface of the sliding plate 27 through the air guide groove 39. This allows the heat inside the main unit chassis 1, the auxiliary chassis 2 and the protective shell 3 to be discharged to the outside of the main unit chassis 1 and the auxiliary chassis 2 more quickly, thereby further improving the heat dissipation effect of the present invention.

[0023] Secondly, by directing airflow through the air duct 39 to the small holes of the sliding plate 27, the probability of external dust entering the main unit case 1 and the secondary unit case 2 is reduced, thereby reducing the accumulation and impact of dust on the surfaces of the internal components installed in the main unit case 1 and the secondary unit case 2, and thus improving the heat dissipation effect in the main unit case 1 and the secondary unit case 2.

[0024] It should be noted that all devices of the present invention are connected to the corresponding internal components or power supply of a computer motherboard via data cables. There are two water boxes 35, and both water boxes 35 are connected to the circulating water pipe 31 via the water outlet tee pipe 34 and the water inlet tee pipe 341, thereby forming a circulating water cooling heat dissipation. At the same time, the external ventilation hole 12 and the internal ventilation hole 201 are the same size and the spacing is also equal.

[0025] Example 2: A flexible hose 5 is fixed to the side of the protective shell 3 near the limiting frame 24. A fixed air guide frame 51 is fixed to one end of the flexible hose 5. The fixed air guide frame 51 is fixed to one side of the auxiliary housing 2. The interior of the fixed air guide frame 51 is a hollow structure. An exhaust port 52 is opened on the side of the fixed air guide frame 51 near the inner ventilation hole 201. The exhaust port 52 is aligned with the inner ventilation hole 201. Specifically, based on Embodiment 1, when the water pump 33 and motor 41 are started, the motor 41 drives the fan blade 42 to blow air into the inside of the protective shell 3. At this time, part of the hot air inside the protective shell 3 enters the inside of the air guide groove 39 and blows it outward and is discharged, while another part of the hot air enters the inside of the hose 5. Hot air enters the interior of the fixed air guide frame 51 through the hose 5 and is discharged to the outside through the exhaust port 52, thereby further improving the efficiency of hot air discharge from the protective shell 3 and also improving the efficiency of the built-in water cooling circulation heat dissipation of the present invention.

[0026] It should be noted that the exhaust vent 52 is located on the side close to the external ventilation hole 12 and the internal ventilation hole 201. When the exhaust vent 52 blows air outward, heat is discharged outward through the internal ventilation hole 201 or the external ventilation hole 12. At this time, the airflow blown out by the exhaust vent 52 can form a jet inside the main unit chassis 1 and the auxiliary chassis 2, carrying the hot air inside the main unit chassis 1 and the auxiliary chassis 2. This allows the hot air inside the main unit chassis 1 and the auxiliary chassis 2 to be discharged to the outside of the main unit chassis 1 more quickly under the action of the air jet blown out by the exhaust vent 52, thereby further improving the heat dissipation efficiency of the present invention.

[0027] Example 3: The bottom of the main unit 1 is provided with a bottom air vent 6, the inner wall of the main unit 1 is fixed with a spring assembly 61, the surface of the spring assembly 61 is fixed with a ventilation plate 62, the bottom of the auxiliary unit 2 is fixed with an extension frame 7, a water storage chamber 71 is provided at the position where the auxiliary unit 2 and the extension frame 7 meet, a water inlet 711 is provided on one side of the water storage chamber 71, a support plate 72 is fixed inside the water storage chamber 71, and an airbag 73 is fixed on the top of the support plate 72. A first hose 74 is fixed to one side of the airbag 73. An air pump 75 is fixed to the bottom of the main unit box 1. The first hose 74 passes through the bottom of the main unit box 1 and is connected to the air pump 75. A waterproof pipe 76 is fixed to the inner wall of the water storage chamber 71. An extension pipe 77 is slidably and sealed inside the waterproof pipe 76. An exhaust hole 771 is opened on the surface of the extension pipe 77. The extension tube 77 is connected to the airbag 73 through the second hose 78. A heat sink 79 is fixed at the bottom of the inner cavity of the main unit 1, and one end of the heat sink 79 is located inside the water storage chamber 71. A magnetic strip 8 is fixed on the bottom of the main unit 1 near the extension tube 77, and the magnetic strip 8 is attracted to the extension tube 77. Specifically, based on Embodiment 1 and Embodiment 2, before assembling the main chassis 1 and the auxiliary chassis 2, cooling water can be injected into the water storage chamber 71 through the water inlet 711, so that the water storage chamber 71 is filled with cooling water and the heat sink 79 is immersed in the cooling water. Then, following the steps of Embodiment 1, the limiting rod 21 is inserted into the connecting rod 22, so that the auxiliary chassis 2 is inserted into the main chassis 1, and the limiting bracket 24 is sleeved on the outside of the bolts of the bolt and nut assembly 11. Then, the distance between the main chassis 1 and the auxiliary chassis 2 is fixed. When the auxiliary chassis 2 is inserted into the main chassis 1 and the distance between the main chassis 1 and the auxiliary chassis 2 is adjusted, the auxiliary chassis 2 abuts against the ventilation plate 62. The auxiliary chassis 2 pushes the ventilation plate 62 and squeezes the spring assembly 61, so that the ventilation plate 62 is adjusted above the bottom air vent 6. At the same time, the auxiliary chassis 2 drives the extension frame 7 to be inserted into the bottom air vent 6. Under the action of the spring assembly 61, the ventilation plate 62 is always in contact with the surface of the extension frame 7. This allows the bottom air vent 6 to be adjusted under the combined action of the extension frame 7 and the ventilation plate 62, so that the hot air in the main unit 1 and the auxiliary unit 2 can be further discharged to the outside through the ventilation plate 62, thereby further improving the heat dissipation efficiency of the present invention.

[0028] Furthermore, after the main unit 1 and the secondary unit 2 are assembled, the extension tube 77 can be pulled out from the inside of the waterproof tube 76, so that the extension tube 77 comes into contact with the magnetic strip 8, and the magnetic strip 8 is used to attract and fix the extension tube 77. In subsequent use, the motherboard controls the start of the air pump 75, so that the air pump 75 pumps air to the airbag 73 through the first hose 74, so that the air in the airbag 73 is delivered to the extension tube 77 through the heat sink 79. This causes the air inside the airbag 73 to be ejected to the outside through the vent 771. Since the vent 771 is located below the ventilation plate 62, the airflow ejected from the vent 771 is then ejected into the interior of the main unit 1 through the ventilation plate 62. This increases the air pressure inside the main unit 1, causing the hot air inside the main unit 1 to be ejected to the outside more quickly through the external ventilation hole 12, the internal ventilation hole 201, or the sliding plate 27, driven by the airflow ejected from the vent 771. This further improves the heat dissipation efficiency of the present invention. At the same time, the airbag 73 is immersed in cooling water, and the temperature of the air inside the airbag 73 is lower than the temperature around the various internal components in the main unit chassis 1 and the secondary unit chassis 2. As a result, the gas ejected from the exhaust vent 771 can further improve the heat exchange efficiency of the hot air inside the main unit chassis 1 and the secondary unit chassis 2 after entering the interior of the main unit chassis 1 and the secondary unit chassis 2, thereby further improving the heat dissipation performance of the present invention.

[0029] Furthermore, during the flow of hot air inside the main chassis 1 and the secondary chassis 2, some of the heat will be transferred to the heat sink 79. One end of the heat sink 79 is immersed in the cooling water in the water storage chamber 71. Thus, the heat sink 79 can absorb some of the heat inside the main chassis 1 and the secondary chassis 2 and transfer it to the cooling water in the water storage chamber 71, thereby further performing water cooling operation on the main chassis 1 and the secondary chassis 2. Meanwhile, when the airbag 73 is pumped or sucked in by the air pump 75, the volume of the airbag 73 will change continuously. The change in the volume of the airbag 73 can be used to drive the flow of cooling water in the water storage chamber 71, causing the cooling water to be agitated, thereby increasing the speed of heat diffusion in the cooling water. This improves the cooling water's ability to absorb heat from the heat sink 79 and allows it to quickly distribute heat to various parts of the cooling water, thereby enhancing the cooling water's heat dissipation effect.

[0030] It should be noted that the extension tube 77 is slidably sealed inside the waterproof tube 76. Regardless of the distance between the main unit 1 and the secondary unit 2, after one end of the extension tube 77 is attracted and fixed to the magnetic strip 8, the exhaust hole 771 can spray air when exposed to the air. The part of the exhaust hole 771 located inside the waterproof tube 76 is sealed by the waterproof tube 76, which prevents the cooling water in the water storage chamber 71 from entering the interior of the extension tube 77 through the exhaust hole 771, thereby preventing the leakage of cooling water.
