Description

Technical Field

[0001] The invention relates to the technical field of computer cooling devices, in particular to a computer cooling system. Background Art

[0002] With the continuous improvement of computer hardware performance, especially under the frequent calculation and high-load operation of core components such as graphics processing unit (GPU), central processing unit (CPU) and storage devices, the heat generated by the computer is increasing, resulting in an increase in the overall temperature of the system. If the heat is not dissipated in a timely and effective manner, it may cause damage to the computer hardware, system instability and even directly affect the performance of the computer. Therefore, the research and development of computer cooling technology has become a vital direction in the information technology industry.

[0003] After searching, it was found that the prior art publication number is CN 109753124 A, which discloses a cooling device, which relates to the computer field and mainly solves the problem that the existing chassis cooling device cannot find the cause of damage in time and cannot effectively cool down and prevent dust from entering the chassis. The cooling device includes a main body, a heat dissipation device, a host and a second isolation plate. The bottom of the main body is provided with a second isolation plate, and the left and right ends of the second isolation plate are fixedly connected to the inner surface of the main body. A ventilation area is provided below the second isolation plate, and a host is placed above the second isolation plate. Fixing devices are symmetrically provided on the left and right ends of the host, and the fixing devices include a limiting layer, a vent hole, and a fixing plate. This solution can effectively reduce the temperature while preventing dust from entering the device. At the same time, it can monitor the cooling terminal and understand the cause of damage to the cooling terminal at the first time, which is more efficient and convenient.

[0004] Therefore, based on the above search and in combination with the existing technology, when the above solution is used in a hot environment, when the computer is cooled by extracting outside air, the effect of the radiator will be significantly reduced, because it relies on the outside air to take away the heat, resulting in the heat inside the computer cannot be effectively reduced. In order to compensate for this problem, the cooling fan needs to increase the speed to speed up air circulation, which not only increases the noise, but also makes it difficult for the computer to maintain stable operation in a high temperature environment. For this reason, we propose a computer cooling system. Summary of the invention

The free end of the liquid outlet pipe 21 is fixedly connected to the lower water tank 302, and the return pipe 23 is fixedly connected to the upper water tank 301. Specifically, the liquid outlet pipe 21 is divided into two sections. The two sections of the liquid outlet pipe 21 connect the heat conduction pipe 26 inside the cooling cylinder 4, so that the heat conduction pipe 26 inside the lower water tank 302 is The cooling liquid first flows into the heat pipe 26 through the liquid outlet pipe 21, and finally flows into the inside of the stabilizing cylinder 207. The inner end of the stabilizing cylinder 207 is sleeved with a movable cylinder 206, and the inner end of the movable cylinder 206 is fixedly installed with an isolation plate. The outer surface of the movable cylinder 206 is fixedly sleeved with a sealing rubber ring, which fits tightly with the inner surface of the stabilizing cylinder 207 to increase the sealing and prevent leakage. The outer surfaces of the outer cylinder 201 and the outer surfaces of the movable cylinder 206 are both provided with air holes.

[0041] like Figure 4 - Figure 6 As shown, the left end of the movable cylinder 206 is fixedly installed with a support sleeve 202, and the inner left end of the support sleeve 202 is fixedly installed with a telescopic tube 210, and the right end of the telescopic tube 210 is tightly fitted with the inner wall of the support sleeve 202, and the telescopic tube 210 is made of fatigue-resistant rubber material, so that its service life is further increased, and the outer surface of the right end of the telescopic tube 210 is fixedly provided with a sealing rubber ring, and is tightly fitted with the inner wall of the support sleeve 202 to further increase the air tightness, and the right end of the support sleeve 202 A plurality of vent holes are provided, a support plate is fixedly installed at the left end of the support sleeve 202, a plurality of vent holes 212 are provided on the outer surface of the support plate, the vent holes 212 are arranged in a ring shape, and a sealing plate 209 is provided on the left side of the vent holes 212, a sealing ring is provided on the outer surface of the sealing plate 209, the area of ​​the sealing plate 209 is larger than the aperture of the vent holes 212, when the sealing plate 209 is attached to the left side of the support plate, and the vent holes 212 are covered, the air cannot pass through the vent holes 212 at this time The inner end of the support plate is fixedly mounted with a plurality of airbags 208, the airbags 208 are made of elastic rubber material, and are smaller than the size of the vent holes 212 and the sealing plate 209 before expansion, the airbags 208 correspond to the vent holes 212, and the airbags 208 are connected to the telescopic tube 210 through a synchronous air pipe 211, the airbags 208 are located on the left side of the sealing plate 209, and the airbags 208 are fixedly connected to the sealing plate 209, and a passive ring 208 is provided on the left side of the telescopic tube 210 5. The outer surface of the passive ring 205 is fitted with the inner wall of the outer tube 201. The left end of the telescopic tube 210 is fixedly connected with a vent pipe 214. The outer surface of the vent pipe 214 is provided with air holes. The inner end of the passive ring 205 is fixedly installed with a sleeve, which is sleeved on the outer surface of the vent pipe 214. When the passive ring 205 moves to the right, the sleeve moves to expose the air holes on the outer surface of the vent pipe 214. On the contrary, the sleeve moves to the left to block the air holes on the outer surface of the vent pipe 214.

[0042] A plurality of limit blocks 203 are fixedly installed at the inner end of the outer cylinder 201. The limit blocks 203 are respectively distributed on the left and right sides of the inner part of the outer cylinder 201, and the passive ring 205 is located between the limit blocks 203 on both sides. When the passive ring 205 moves to the left side of the outer cylinder 201, it contacts the limit block 203 on the left side and squeezes the passive ring 205 to move to the right side. When the passive ring 205 moves to the right side of the outer cylinder 201, it contacts the limit block 203 on the right side, and the passive ring 205 moves to the left side.

[0043] like Figure 3 , Figure 5 - Fig. 9 The telescopic tube 210 is connected to the outer cylinder 201 through a return spring 204, and a resistance spring 213 is arranged inside the telescopic tube 210. A centrifugal fan 25 is fixedly installed at the left end of the outer cylinder 201. The centrifugal fan 25 can generate a strong airflow and a high pressure, and effectively create a greater negative pressure, and maintain a high pressure and flow within a certain range. When the sealing plate 209 blocks the vent 212, the support sleeve 202 and the movable cylinder 206 are moved to the left side by the attraction of the centrifugal fan 25 when it is working. Specifically, the centrifugal fan 25 works The attraction generated during operation is greater than the elastic force of the return spring 204, so that the support sleeve 202 and the movable cylinder 206 can move to the left. At this time, the centrifugal fan 25 continuously extracts air during operation. At this time, a small amount of air passes through the gap between the passive ring 205 and the support sleeve 202, and most of the air begins to squeeze the right end of the telescopic tube 210 and deform it. At this time, the telescopic tube 210 shrinks and squeezes the air inside to the inside of the airbag 208, so that the airbag 208 always remains in an expanded state and squeezes the sealing plate 209 to block the vent 212;

[0044] like Figure 8 , Fig. 9As shown, two conducting sleeves 24 are fixedly installed at the right inner end of the stabilizing cylinder 207, and the two conducting sleeves 24 are respectively connected to the liquid outlet pipe 21 and the return pipe 23. A sealing ring 216 is fixedly installed at the inner end of the conducting sleeve 24, and a sliding rod is passed through the inner end of the sealing ring 216. A sealing plug 215 is fixedly installed at the right end of the sliding rod. The sealing plug 215 is made of rubber, and the diameter of the sealing plug 215 is smaller than the diameter of the sealing ring 216. The sealing plug 215 is located on the right side of the sealing ring 216. The liquid outlet spring 216 is provided between the sliding rod and the sealing ring 216. 17 is connected, a plurality of liquid outlet holes are formed on the outer surface of the sealing ring 216, and the sealing plug 215 covers the liquid outlet holes. Then, when the sealing plug 215 moves to the right, the liquid in the stabilizing cylinder 207 can flow out through the liquid outlet holes under the squeezing of the movable cylinder 206. Specifically, the sealing plug 215 inside the conducting sleeve 24 connected to the liquid outlet pipe 21 faces left, and the sealing plug 215 inside the conducting sleeve 24 connected to the reflux pipe 23 faces right, thereby preventing the coolant from flowing back after the coolant flows from the liquid outlet pipe 21 to the inside of the stabilizing cylinder 207.

[0045] Example 2: Please refer to Figure 2 , Figure 3 , Fig.10 - Fig.14 A computer cooling system, based on the first embodiment, comprises a plurality of heat receiving pipes 303, each of which is fixedly connected to the bottom end of an upper water tank 301, and a plurality of heat sinks 310 are fixedly sleeved on the outer surface of the heat receiving pipe 303 to further increase the heat dissipation area, a water spray head 307 is fixedly installed on the inner upper end of the heat receiving pipe 303, and the water spray head 307 is fixedly connected to the upper water tank 301, and a plurality of connecting sleeves 304 are fixedly connected to the upper end of the lower water tank 302, and the connecting sleeves 304 are sleeved on the bottom end of the heat receiving pipe 303 to connect the heat receiving pipe 303 with the lower water tank 302, and the coolant inside the upper water tank 301 is sprayed out from the water spray head 307, and then the coolant is sprayed out. The state of the liquid sprayed out by the water head 307 is an atomized state, and the temperature is rapidly reduced through the principle of evaporative cooling, and finally flows into the lower water tank 302. A plurality of hydrophobic strips 309 are fixedly installed on the inner wall of the heat receiving pipe 303. The hydrophobic strips 309 are arranged in a ring shape, and the heat receiving pipe 303 and the hydrophobic strips 309 are both made of stainless steel with good thermal conductivity. The distances between the hydrophobic strips 309 are equal. Under the action of the hydrophobic strips 309, the coolant increases the contact area with the inner wall of the heat receiving pipe 303. Then, when the coolant flows on the inner wall of the heat receiving pipe 303, the wind blown by the heat dissipation fan 3 passes through the outer surface of the heat receiving pipe 303 during operation, which significantly improves the heat dissipation efficiency.

[0046] like Fig.11 , Fig.12 , Fig.13As shown, a movable plate 306 is slidably installed at the inner end of the heat receiving tube 303, and a plurality of slide grooves are provided on the outer surface of the movable plate 306, which fit with the hydrophobic strip 309. The movable plate 306 and the heat receiving tube 303 are connected by a bellows 305, and a plurality of holes are provided on the outer surface of the movable plate 306, so that the coolant can pass through the holes. The bellows 305 is made of fatigue-resistant rubber material. Then, when the movable plate 306 moves upward, the contact area between the coolant and the inner wall of the heat receiving tube 303 becomes smaller. On the contrary, when the movable plate 306 moves downward, the contact area between the coolant and the inner wall of the heat receiving tube 303 becomes larger, thereby changing the cooling speed of the coolant.

[0047] like Figure 3 , Fig.11 , Fig.12 , Fig.14 As shown, a temperature sensing tube 102 is fixedly installed at the inner bottom end of the air outlet hood 6, and a heating fin 101 is fixedly installed on the outer surface of the temperature sensing tube 102, and both the temperature sensing tube 102 and the heating fin 101 are made of metal materials with good thermal conductivity (such as copper and nickel alloys), and a compression tube 107 is fixedly connected to the right end of the temperature sensing tube 102, and a piston 106 is slidably installed on the inner end of the compression tube 107, and a sealing rubber ring is fixedly sleeved on the outer surface of the piston 106, and it fits tightly with the inner wall of the compression tube 107, and the compression tube 107 is filled with coolant, and a screw 105 is fixedly installed on the left end of the piston 106, and a collar is fixedly installed on the inner left end of the compression tube 107, and a rectangular block is fixedly installed on the inner end of the collar, and the screw 105 is fixedly installed on the inner left end of the compression tube 107. A rectangular groove is provided on the outer surface, and a rectangular block is arranged in the rectangular groove to prevent the screw 105 from rotating when moving left and right. A bimetallic spiral piece 103 is fixedly installed on the inner left end of the temperature sensing tube 102. The bimetallic spiral piece 103 is formed by overlapping two metals with different thermal expansion coefficients. The expansion coefficients of the two metals are different. Therefore, when the bimetallic spiral piece 103 is heated, the two metals will expand to different degrees, causing the shape of the spiral piece to change. A sleeve 104 is fixedly installed on the right end of the bimetallic spiral piece 103, and the sleeve 104 is threadedly sleeved on the outer surface of the screw 105. Therefore, when the bimetallic spiral piece 103 is heated and deformed, the sleeve 104 is driven to rotate, so that the screw 105 can move left and right.

[0048] A folding tube 308 is fixedly installed on the inner upper end of the connecting sleeve 304, and the upper end of the folding tube 308 is fixedly connected to the bottom end of the movable cylinder 206. The folding tube 308 is made of folding-resistant rubber material. The folding tube 308 is slender. The volume of a plurality of folding tubes 308 combined is equal to the volume of the compression tube 107, and the bottom end of the folding tube 308 is connected to the compression tube 107 through the synchronization tube 22. When the piston 106 moves to the left, the coolant inside the folding tube 308 is reduced and drives the movable plate 306 to move downward.

[0049] The working principle of the present invention is:

[0050] During operation, the cooling fans 3 and the centrifugal fans 25 on both sides of the chassis 1 start to work. At this time, the support sleeve 202 is located on the right side inside the outer cylinder 201, and under the extraction effect of the centrifugal fan 25, a small amount of air passes through the gap between the passive ring 205 and the support sleeve 202, and most of the air begins to squeeze the right end of the telescopic tube 210 and deform it. At this time, the telescopic tube 210 shrinks and squeezes the air inside to the inside of the airbag 208, thereby achieving that the airbag 208 always remains in an expanded state and squeezes the sealing plate 209 to block the vent 212. At this time, the support sleeve 202 and the movable cylinder 206 start to move to the left, and compress the return spring 204. As the movable cylinder 206 moves, the coolant in the lower water tank 302 is extracted through the liquid outlet pipe 21, and the coolant first flows into the interior of the cooling cylinder 4. At this time, the air temperature inside the cooling cylinder 4 decreases, and as the cooling fan 3 on the left side of the air outlet hood 6 continues to work, the cold air inside the cooling cylinder 4 begins to be extracted through the upper air hood 7 and the lower air hood 5. The cold air passes through the graphics card and the radiator 12 respectively, and gathers inside the air outlet hood 6, and is then discharged;

[0051] At the same time, when the support sleeve 202 moves to the inner left end of the outer cylinder 201 and contacts the limit block 203 on the left, it squeezes the passive ring 205 to move to the right, and exposes the air holes on the outer surface of the air-permeable tube 214. At this time, the air inside the telescopic tube 210 leaks quickly. At the same time, because the sealing plate 209 is located on the left side of the support sleeve 202, it also moves to the left under the action of negative pressure and begins to squeeze the airbag 208. At this time, the return spring 204 begins to release its elastic force and quickly pushes the support sleeve 202 and the movable cylinder 206 to move to the right, so that the coolant inside the stabilizing cylinder 207 flows to the inside of the upper water tank 301 through the return pipe 23, and under the action of pressure, the coolant inside the upper water tank 301 is sprayed out through the sprinkler head 307 and finally flows to the inside of the lower water tank 302.

[0052] When the temperature inside the air outlet hood 6 becomes higher, the bimetallic spiral sheet 103 is heated and deformed by driving the sleeve 104 to rotate, causing the screw 105 to move to the left, and extracting the coolant inside the folding tube 308 through the synchronous tube 22, causing the movable plate 306 to move downward, so that the contact area between the coolant and the inner wall of the heated tube 303 is increased, thereby improving the heat dissipation efficiency, making it possible to flexibly adjust the cooling degree of the coolant according to the heating condition of the temperature sensing tube 102, and avoid the phenomenon of condensation of water on the outer surface of the heated tube 303 due to overcooling.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed in the present invention, which should be covered by the protection scope of the present invention.
