Description

Technical Field

[0001] The invention relates to the technical field of computer hardware, and in particular to a CPU high-efficiency liquid cooling radiator for coal mining equipment. Background Art

[0002] At present, with the continuous improvement and development of the intelligent level of coal mining in my country, the intelligent level of underground coal mining equipment in coal mines is getting higher and higher. Special embedded single-chip microcomputers, control core computers and other equipment are widely used in coal mining sites, and a large number of CPU chips are widely used. The CPU is the core component of intelligent equipment, and its high-speed operation will generate a lot of heat, so its heat dissipation problem is a key link in fully exerting the hardware functions.

[0003] Existing coal mining equipment radiators often use air cooling, but due to the influence of the environment, the cooling effect of only using air cooling may be poor. For this reason, a liquid cooling cooling method is added. The liquid cooling radiator is usually divided into a pump head and a heat sink with a wind speed. During use, the liquid cooling pump head needs to be fitted with the CPU surface and then locked with bolts. However, during the fitting process of the existing liquid cooling pump head, since the thermal conductivity of air is very low, these air gaps will form thermal resistance and reduce the heat dissipation efficiency. In order to reduce the increase in thermal resistance caused by the presence of air, silicone grease is often applied to the surface of the pump head to make the thermal conductivity between the pump head and the motherboard better. However, according to the characteristics of silicone grease, during continuous use, the silicone grease will harden and volatilize, resulting in poor filling effect and thermal conductivity. At the same time, the coolant in the existing liquid cooling radiator often uses a coolant with a special material. The coolant will accelerate the change of its chemical composition during repeated heating and cooling. High temperature will promote the decomposition of the coolant, while low temperature may make it more viscous and affect fluidity. When the temperature of the CPU is high, in order to improve the heat dissipation effect, the circulation speed of the liquid is often increased, thereby improving the heat dissipation effect. However, this method increases the frequency of heating and cooling of the coolant, thereby reducing its lifespan. In addition, the increased circulation speed causes the actual coolant to absorb heat that does not reach the upper limit, that is, it breaks contact with the CPU surface and performs a cooling cycle, resulting in a limited service life of the coolant, and it is impossible to determine when the coolant will fail. Summary of the invention

[0004] The technical solution of the present invention is aimed at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technologies. The embodiment of the present invention provides a CPU high-efficiency liquid cooling radiator for coal mining equipment to solve the technical problem that in the process of heat dissipation of the existing liquid cooling radiator, the coolant is cooled down before completely absorbing heat due to the flow of the pump body, causing the coolant to fail quickly.

[0005] The embodiment of the present invention adopts the following technical scheme: a high-efficiency liquid-cooled radiator for the CPU of coal mining equipment, comprising an outer shell for wrapping and protecting the CPU, and a long-term liquid-cooled heat dissipation mechanism for efficiently and stably dissipating heat from the CPU, the long-term liquid-cooled heat dissipation mechanism comprising a pipeline assembly for circulating the coolant, and an adjustment assembly for automatically reversing the flow direction of the liquid in the pipeline assembly, the long-term liquid-cooled heat dissipation mechanism comprising a fixed plate, the fixed plate and the shell are connected by studs, a drive motor is arranged in the middle of the fixed plate, a rotating through rod is arranged at the output end of the drive motor, a movable plate is arranged below the fixed plate, and the height of the movable plate is changed by setting a height-controlled telescopic rod between the fixed plate and the movable plate.

[0006] Furthermore, the pipeline assembly includes a liquid inlet pipe, a spiral cooling pipe, an adjustment assembly, a rotating through rod, a liquid outlet pipe and a heat dissipation air plate in sequence according to the flow direction. Heat dissipation air plates are provided at the ends of the liquid inlet pipe and the liquid outlet pipe. The heat dissipation air plates are provided on the outside of the outer shell. The end of the liquid inlet pipe is connected to the spiral cooling pipe. The center of the bottom end of the spiral cooling pipe is connected to the rotating through rod, and the liquid outlet pipe is connected to the rotating through rod.

[0007] Furthermore, the lower surface of the spiral cooling tube is a plane, the upper surface is an arc surface, and the spiral cooling tube is divided into a variable part and a fixed part. The fixed part is composed of a plurality of spiral cooling tubes arranged horizontally, and the variable part is composed of a plurality of spiral cooling tubes with gradually increasing heights.

[0008] Furthermore, the spiral cooling tube is made of elastic deformable material so that it can be elastically deformed and reset, and the connecting ends of the liquid inlet pipe and the liquid outlet pipe with the spiral cooling tube are made of elastic deformable material, and the movable plate is connected to the top of the spiral cooling tube.

[0009] Furthermore, the adjustment component includes a connecting tube body and a connecting hose, the connecting tube body has the same shape as the spiral cooling tube, and connecting blocks that dock with the spiral cooling tube are provided at both ends of the connecting tube body, and sealing rubber rings are provided on the connecting blocks, the connecting tube bodies are connected by a connecting hose, a position sensor is provided on the lower surface of the connecting tube body, a baffle with a through hole is provided in the connecting tube body, a spiral block is provided at the position of the baffle through hole, a limiting block is provided at the connecting port of the connecting hose, and double electric telescopic rods for adjusting the position are respectively provided between the limiting block and the spiral block.

[0010] Furthermore, the limiting block and the spiral blocking block move in an offset manner.

[0011] Compared with the prior art, the beneficial effects of the present invention are: First, the pump head of the existing liquid cooling radiator is changed from the original fixed form to an adjustable pump head, and the liquid cooling radiator is divided into multiple cooling forms during use, such as a combination of liquid cooling and air cooling, so that when the temperature is low, the radiator does not need too much intervention from liquid cooling, and air cooling can be completed. When the temperature of the radiator is high, the use of air cooling may cause the cooling performance to not keep up, so liquid cooling intervenes to assist in heat dissipation. If the temperature continues to rise, liquid cooling is fully involved to greatly improve the heat dissipation effect, so that the power of the radiator is lower than that of ordinary liquid cooling radiators; Secondly, during the liquid cooling process, the radiator and the CPU surface do not need to be coated with silicone grease. Since it adopts a spiral disk type, when all liquid cooling is adopted, the heat dissipation tubes will be rolled up, thereby squeezing the existing gaps, and the surface of the spiral cooling tube in the heat dissipation mechanism and the CPU surface are gradually moving, which has an effect similar to that of a mobile phone film, and can gradually squeeze out the gas. In the process of gradual movement, the presence of air can be reduced as much as possible, thereby avoiding the presence of air between the spiral cooling tube and the CPU affecting heat conduction. In addition, during use, under different conditions, the circulation time of the liquid flow will also change, and the actual spiral cooling tube surface and the CPU surface will gradually move. The length of the spiral cooling tube remains unchanged, but the flow path of the spiral cooling tube is different under different conditions. When the temperature rises and the flow rate increases, the path increases, so that the time for the coolant to go through a cycle is not greatly increased, which greatly improves the service life of the coolant. In addition, the protective liquid can be exchanged inside and outside through the adjustment component during the movement, thereby improving the overall heat absorption uniformity (because when the existing coolant is conducting heat, the liquid that fits the inside is always the outermost, resulting in relatively high heat on the outermost side, and a small temperature difference between the inside and the outside, which makes the heat conduction effect worse. Under the action of the spiral block, the liquid can be exchanged inside and outside to improve the heat absorption effect); In summary, by changing the structural form of the pump head, the pump head is made variable. When the temperature is low, dual heat dissipation is performed through relatively low-speed water cooling and air cooling to reduce the number of coolant circulations. When the temperature is high and air cooling is no longer possible, the cooling system truly begins to control, and the pump head deforms to fill the center gap to prevent air from affecting heat transfer. At the same time, the flow tube changes, so that the position of the liquid can change when the internal liquid circulates, and continuous exchange is carried out to improve the heat absorption effect. In addition, in the process of circulation, the liquid will not flow away until it reaches the maximum heat absorption value, which greatly improves the service life and the cooling effect of the liquid.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] Combine the following Figures 1 to 10 As shown, an embodiment of the present invention provides a CPU high-efficiency liquid cooling radiator for coal mining equipment, including an outer shell 1 for wrapping and protecting the CPU, and also including a long-term liquid cooling heat dissipation mechanism 2 for efficiently and stably dissipating heat from the CPU, the long-term liquid cooling heat dissipation mechanism 2 includes a pipeline component for circulating the coolant, and an adjustment component 28 for automatically reversing the flow direction of the liquid in the pipeline component, the long-term liquid cooling heat dissipation mechanism 2 includes a fixed plate 22, the fixed plate 22 and the shell are connected by studs, a drive motor 27 is arranged in the middle of the fixed plate 22, a rotating through rod 26 is arranged at the output end of the drive motor 27, a movable plate 23 is arranged below the fixed plate 22, and the height of the movable plate 23 is changed by setting a height-controlled telescopic rod 24 between the fixed plate 22 and the movable plate 23.

[0021] When working, the pump head is variable by changing its structural form. When the temperature is low, dual heat dissipation is performed through relatively low-speed water cooling and air cooling to reduce the number of coolant circulations. When the temperature is high and air cooling is impossible, the cooling system really starts to control, the pump head deforms to fill the center gap to prevent air from affecting heat transfer. At the same time, the flow tube changes, so that the position of the liquid can change when the internal liquid circulates, and continuous exchange is carried out to improve the heat absorption effect. In addition, during the circulation process, the liquid will not flow away until it reaches the maximum heat absorption value, which greatly improves the service life and the cooling effect of the liquid.

[0022] Specifically, the pipeline assembly includes a liquid inlet pipe 29, a spiral cooling pipe 25, an adjustment assembly 28, a rotating rod 26, a liquid outlet pipe and a heat dissipation air plate 21 in sequence according to the flow direction. The ends of the liquid inlet pipe 29 and the liquid outlet pipe are provided with heat dissipation air plates 21. The heat dissipation air plate 21 is arranged on the outside of the outer shell 1. The end of the liquid inlet pipe 29 is connected to the spiral cooling pipe 25. The center of the bottom end of the end of the spiral cooling pipe 25 is connected to the rotating rod 26, and the liquid outlet pipe is connected to the rotating rod 26.

[0023] Specifically, the lower surface of the spiral cooling tube 25 is a plane, and the upper surface is an arc surface, and the spiral cooling tube 25 is divided into a variable part and a fixed part. The fixed part is composed of a plurality of spiral cooling tubes 25 arranged horizontally, and the variable part is composed of a plurality of spiral cooling tubes 25 with gradually increasing heights.

[0024] During operation, when the coolant is circulating, the lower surface of the spiral cooling tube 25 contacts the surface of the CPU. In order to improve the thermal conductivity of the spiral cooling tube 25, the spiral cooling tube 25 is made of a thermally conductive metal material with deformation ability, such as copper-aluminum alloy. In order to ensure that the deformation ability is within the range, when the spiral cooling tube 25 is not rolled up, the gap between each spiral tube does not need to be too large (a gap is sufficient to enable air heat dissipation). Similarly, it is sufficient to have a height difference between each level of the deformation part, as long as it can gradually contact the CPU surface. In places where there is no need to contact the CPU surface, materials with stronger deformation recovery ability, such as silicone rubber, polyethylene and thermoplastic elastomers, can be used.

[0025] Specifically, the spiral cooling tube 25 is made of elastic deformable material so that it can be elastically deformed and reset, and the connection ends of the liquid inlet pipe 29 and the liquid outlet pipe with the spiral cooling tube 25 are made of elastic deformable material, and the movable plate 23 is connected to the top of the spiral cooling tube 25.

[0026] During operation, the spiral cooling tube 25 can be deformed.

[0027] Specifically, the adjustment assembly 28 includes a connecting tube body 282 and a connecting hose 288. The connecting tube body 282 has the same shape as the spiral cooling tube 25, and connecting blocks 281 for docking with the spiral cooling tube 25 are provided at both ends of the connecting tube body 282, and a sealing rubber ring is provided on the connecting block 281. The connecting tube bodies 282 are connected by a connecting hose 288, and a position sensor 287 is provided on the lower surface of the connecting tube body 282. A baffle 284 with a through hole is provided in the connecting tube body 282, and a spiral block 285 is provided at the position of the through hole of the baffle 284. A limiting block 286 is provided at the connection port of the connecting hose 288, and a double electric telescopic rod 283 for adjusting the position is provided between the limiting block 286 and the spiral block 285. The double electric telescopic rod 283 is composed of two electric telescopic rods operating in opposite directions.

[0028] Specifically, the limiting block 286 and the spiral blocking block 285 move in an offset manner.

[0029] Working principle: During use, in the initial state of the cooling mechanism, there are gaps between the diameters of the spiral cooling tube 25, so that when the temperature is low, air can be used for heat dissipation. When the temperature is high, partial liquid cooling is required. At this time, the long-term liquid cooling heat dissipation mechanism 2 starts to work, and the position of the changing part remains unchanged. The coolant enters the spiral cooling tube 25 through the heat dissipation air plate 21 and the liquid inlet pipe 29. At this time, the spiral block 285 in the adjustment component 28 in the spiral cooling tube 25 blocks the through hole of the baffle 284, and the limiting block 286 between the limiting block 286 and the connecting hose 288 is opened. At this time, the liquid cannot flow normally around the spiral cooling tube 25, and can only directly enter the fixed part of the spiral cooling tube 25 through the connecting hose 288 to dissipate the heat of the CPU. At this time, the CPU is dissipated again, and the diameter of the spiral cooling tube 25 of the fixed part still has a gap in the initial state. At this time, the heat dissipation is performed by combining air and liquid cooling. However, under the condition of high power consumption of CPU, the combined method cannot guarantee the heat dissipation effect. At this time, the changing part of the spiral cooling tube 25 begins to intervene, so that the liquid cooling contact with the CPU increases, the air cooling decreases, and the flow rate increases. In order to avoid insufficient heat absorption of the coolant due to the increase in flow rate, the height-controlled telescopic rod 24 is extended to drive the movable plate 23 to move downward. The movable plate 23 moves downward to squeeze the movable part of the spiral cooling tube 25 so that the movable part gradually moves downward. Since the height of the spiral cooling tube 25 of the movable part is gradually increased, in the process of lowering the spiral cooling tube 25, the spiral cooling tube 25 also gradually contacts with the CPU surface. When one of the movable parts After the spiral cooling tube 25 of the moving part contacts the CPU surface, the position sensor 287 located on the lower surface of the connecting tube body 282 is squeezed, indicating that cooling has been involved at this place. At this time, the double electric telescopic rod 283 begins to intervene, so that the limiting block 286 blocks the hole at the connecting hose 288, and the hole at the spiral blocking block 285 is opened. At this time, the coolant will flow through this part of the spiral cooling tube 25, thereby lengthening and improving the cooling path of the coolant (although the flow rate of the coolant increases after the temperature is high, the flow time does not change due to the lengthened path, thereby increasing the heat absorption time of the coolant, and its heat absorption cooling cycle does not decrease, thereby improving the service life); When all the spiral cooling tubes 25 of the changing part are involved in the work, the driving motor 27 will take the initiative to make the spiral cooling tubes 25 with gaps shrink, eliminate the gaps between the tubes, and at this time, the plane moves horizontally between the planes, which can greatly reduce the presence of air. At this time, the spiral cooling tubes 25 are fully utilized for heat dissipation. If the driving motor 27 needs to be reset, it can be reversed under the action of the material of the spiral cooling tube 25 and the driving motor 27 to complete the reset; In summary, by changing the structural form of the pump head, the pump head is made variable. When the temperature is low, dual heat dissipation is performed through relatively low-speed water cooling and air cooling to reduce the number of coolant circulations. When the temperature is high and air cooling is no longer possible, the cooling system truly begins to control, and the pump head deforms to fill the center gap to prevent air from affecting heat transfer. At the same time, the flow tube changes, so that the position of the liquid can change when the internal liquid circulates, and continuous exchange is carried out to improve the heat absorption effect. In addition, in the process of circulation, the liquid will not flow away until it reaches the maximum heat absorption value, which greatly improves the service life and the cooling effect of the liquid.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
