Description

Technical Field

[0001] The present invention relates to the technical field of heat dissipation, and particularly to a high-utilization heat dissipation device based on a heat pipe. Background Art

[0002] With the rapid development of electronic technology, the integration of electronic devices has been continuously improved, the number of components on a circuit board (PCB) has increased day by day, and the power consumption has also increased accordingly. In application scenarios with high power consumption or high-density component layouts, a large amount of heat is generated during the operation of the circuit board. In the prior art, heat pipes are applied to the thermal management system of the circuit board. A heat pipe is an efficient heat conduction component based on the phase change principle, which can quickly and evenly conduct the heat generated by the circuit board to the entire board surface in a short time. It is mainly used to keep the temperature of a specific area or object uniform and stable. It is usually made of a material with good thermal conductivity and can evenly distribute heat on its surface, thereby achieving a high temperature uniformity. Heat pipes are widely used in the fields of electronic devices, scientific research experiments, industrial processing, environmental testing, etc., especially in occasions where precise temperature control is required.

[0003] In the existing technology, high-temperature overheating phenomena will occur during the use of heat pipes on the circuit board. The heat pipe itself is installed together with a radiator to ensure that the temperature of the heat pipe is reduced by heat dissipation through the radiator during use, so as to achieve repeated use. However, the current heat dissipation technology during the use of heat pipes on the circuit board usually relies on methods such as fans, heat pipes, and water cooling to reduce the operating temperature of the heat pipe. In the water cooling method, condensate is mainly used for heat dissipation, and the overheat temperature of the heat pipe is adsorbed and carried away by continuously circulating the condensate. Due to the continuous flow and circulation of the condensate, the heat absorbed by the condensate each time is not proportional to the condensate, resulting in low utilization rate of the condensate during use.

[0013] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation manners.

[0014] Refer to Figure 1 - Figure 8 As shown, the embodiment of the present invention provides a high-utilization heat dissipation device based on a heat pipe, including: Box body 1; Heat pipe 2, a heat pipe 2 is arranged inside the box body 1, and a liquid metal plate is fixedly connected to the top end of the heat pipe 2; used to conduct the heat on the heat pipe to the outside for heat dissipation; The heat dissipation component 3 includes a water cooling component arranged inside the box body 1, and a valve component penetrates through the top of the box body 1 at the top of the heat dissipation component 3; The water cooling component includes a cooler 301 arranged at the top of the box body 1. The cooling end of the cooler 301 is connected to a cold air pipe 302 through a pipeline. One end of the cold air pipe 302 extends vertically into the box body 1. A heat dissipation pipe 303 is sleeved outside the cold air pipe 302 inside the box body 1. The cold air pipe 302 and the heat dissipation pipe 303 are distributed in a mesh pattern inside the box body 1 and are connected to the top of the heat dissipation plate 2 and are attached to the liquid metal plate. The other end of the cold air pipe 302 penetrates upward through the heat dissipation pipe 303 and the inside of the box body 1 and is fixedly connected to an airbag 304. The airbag 304 is communicated with the other end of the cold air pipe 302. The top of the heat dissipation pipe 303 penetrates through the inside of the box body 1 and is connected to a condenser 305 through a pipeline; The valve component includes a valve unit 306. The valve unit 306 includes a left valve port 306b and a right valve port 306c. The left valve port 306b is communicated between the cooler 301 and the input end 302a of the cold air pipe 302, and the right valve port 306c is communicated between the output end 302b of the cold air pipe 302 and the outside; There is a one-way valve 307 arranged on the cold air pipe 302 below the valve unit 306, and a ventilation valve 308 is arranged between the airbag 304 and the other end of the cold air pipe 302; The heat dissipation component 3 of the heat dissipation plate 2 further includes an opening and closing component, and the opening and closing component is used to close the one-way valve 307 and the ventilation valve 308 when the airbag 304 expands; The placement unit 4 includes a placement plate 401 arranged below the heat dissipation plate 2, and the bottom end of the placement plate 401 is connected to the box body 1 through a first spring 402.

[0015] During use, the circuit board transfers heat to the heat pipe 2, causing the temperature on the heat pipe 2 to rise. Since the liquid metal plate refers to a plate-like structure made of liquid metal material, it usually has characteristics such as flexibility, heat conduction, and deformability. The liquid metal material refers to a special type of material that is in a liquid state under specific conditions (usually at normal temperature or lower temperature) but still retains the intrinsic properties of metal (such as electrical conductivity, heat conductivity, metallic luster, etc.). In this embodiment, a gallium-tin alloy type liquid metal plate is used. The gallium-tin alloy type liquid metal plate is in a solid state and has the effect of fast heat conduction speed. Therefore, the heat on the heat pipe 2 is quickly conducted to the liquid metal plate, and by using the excellent thermal conductivity of the liquid metal plate, the heat is efficiently conducted from the heat pipe 2 to the external heat dissipation structure. The heat pipe 2 and the liquid metal plate are placed on the placement plate 401. Subsequently, the placement plate 401 first compresses the first spring 402 downward through elastic connection, and then the first spring 402 pushes the heat pipe 2 upward through its elastic force to contact the heat dissipation component 3. Since the cooler 301 and the condenser 305 are provided by the prior art, the cooler 301 and the condenser 305 respectively output cold air and condensate. The condenser 305 is started, and the one-way valve 307 and the ventilation valve 308 are opened, so that the cold air enters the valve body 306a through the left valve port 306b of the valve unit 306. Subsequently, the cold air in the valve body 306a presses against one end of the piston rod 306d to the right through air pressure, so that the cold air slowly flows into the cold air pipe 302 through the left valve port 306b. At the same time, the condensate also flows into the condensate pipe through pipeline connection. When the cold air in the cold air pipe 302 continuously flows from the input end 302a to the output end 302b of the cold air pipe 302, a part of the cold air will be diverted and flow into the airbag 304, causing the airbag 304 to start to bulge. Subsequently, when the operator observes that the airbag 304 bulges, the one-way valve 307 and the ventilation valve 308 are closed, so that the airbag 304 is not connected to the cooler 301 and the cold air pipe 302, and the cold air in the cooler 301 cannot flow into the cold air pipe 302, and the airbag 304 no longer bulges further, so that the cold air fills the entire cold air pipe 302. At the same time, the cold air at the output end 302b of the cold air pipe 302 flows into the right valve port of the valve body, so that the cold air at the output end 302b presses against the other end of the piston rod. Since the input end 302a and the output end 302b of the cold air pipe 302 are connected, the air pressures at both ends are the same. Therefore, the piston rod remains stationary between the left valve port and the right valve port, so that the cold air at the output end 302b cannot push the piston rod to move leftward into the exhaust port for exhaust. When the heat of the heat pipe 2 is conducted to the liquid metal plate and the temperature becomes high, the liquid metal plate transfers its heat to the condensate through the heat dissipation pipe 303. Subsequently, the condensate reduces the heat of the heat pipe 2 by absorbing the transferred heat. At the same time, since the condensate continuously absorbs heat, its own heat also increases accordingly. The cold air in the cold air pipe 302 sleeved inside the heat dissipation pipe 303 slowly absorbs the condensate, and then the temperature of the cold air continuously rises.The cold air is continuously expanded and activated, the air pressure is increased, and the fluidity is continuously improved. Since the one-way valve 307 is closed, the cold air after heat absorption cannot flow back to the input end 302a of the cold air pipe 302, but can only flow to the output end 302b of the cold air pipe 302, causing the cold air after heat absorption to flow into the right valve port 306c of the valve body 306a. The air pressure of the cold air after heat absorption flowing in from the output end 302b of the cold air pipe 302 is stronger than the air pressure at the input end 302a of the cold air pipe 302. At this time, the air pressure in the valve body 306a is no longer balanced, so that the piston rod 306d in the valve body 306a is pushed to the right to block the left valve port 306b, and the piston rod 306d no longer blocks the exhaust port 306e in the right valve port 306c. Thus, the cold air after heat absorption is discharged to the outside through the exhaust port 306e, realizing the cooling of the heat dissipation plate 2. At the same time, the one-way valve 307 and the ventilation valve 308 are opened, and the cold air in the airbag 304 flows back into the cold air pipe 302 again, and the airbag 304 shrinks and returns to its original state. As the cold air after heat absorption is continuously discharged, the air pressure in the right valve port 306b of the valve body 306a decreases, so that the piston rod 306d in the valve body 306a moves to the right to block the right valve port 306b, and the cold air in the cooler 301 starts to flow into the cold air pipe 302 through the left valve port 306b of the valve and the one-way valve 307 to perform the above operation process for heat dissipation.,

[0016] Reference Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 And Figure 8 As shown, it includes sensors for detecting the expansion of the airbag 304. The one-way valve 307 and the ventilation valve 308 are both solenoid valves, which are used to close when the sensors detect that the expansion of the airbag 304 reaches a predetermined pressure; The opening and closing assembly includes: a chute plate 309, a sliding plate 310, a first rack plate 311, a first rotating gear 312, a rotating rod 313, a first rotating wheel 314, a second rotating wheel 315, a second rotating gear 316, a second rack plate 317 and a third rotating gear 318. There are chute plates 309 fixed to the top of the box body 1 on both sides of the airbag 304. Inside the chute plate 309, there is a sliding plate 310 slidably connected above the airbag 304. A first rack plate 311 is fixedly connected to the side of the sliding plate 310. The side of the first rack plate 311 is engaged with a first rotating gear 312. The middle of the first rotating gear 312 penetrates and is fixedly connected with a rotating rod 313. One end of the rotating rod 313 is fixedly connected with a first rotating wheel 314, and the other end is fixedly connected with a second rotating gear 316. The first rotating wheel 314 is connected to the second rotating wheel 315 by a belt. The side of the second rotating gear 316 is engaged with a second rack plate 317, and the side of the second rack plate 317 is engaged with a third rotating gear 318; The opening and closing assembly further includes: a fixed rod 319, a fourth rotating gear 320, a third rack plate 321, a push plate 322, a push rod 323, a cylinder 324, a second spring 325, an exhaust pipe 326 and a ventilation pipe 327. A vertical fixed rod 319 passes through and is fixedly connected to the middle of the third rotating gear 318. The top of the fixed rod 319 is fixedly connected to a fourth rotating gear 320. The side of the fourth rotating gear 320 is engaged with a third rack plate 321. One end of the third rack plate 321 is fixedly connected to a push plate 322. One end of the push plate 322 is fixedly connected to a push rod 323. The surface of the push rod 323 is sleeved with a cylinder 324. The push rod 323 and the inside of the cylinder 324 are elastically connected by a second spring 325. Above the push rod 323, there is a ventilation pipe 327 arranged at the top of the cylinder 324; The valve unit 306 includes a valve body 306a pipeline-connected to the cold air pipe 302. Inside the valve body 306a, there is a piston rod 306d slidably connected between a left valve port 306b and a right valve port 306c. Above the piston rod 306d, there is an exhaust port 306e opened at the top of the right valve port 306c; The surface of the one-way valve 307 is fixedly connected to the second rotating wheel 315, and the surface of the ventilation valve 308 is fixedly connected to the fixed rod 319.

[0017] When the cold air enters and the airbag 304 expands as described above, an existing sensor directly controls the electronic valve. Subsequently, the airbag 304 expands and pushes the sliding plate 310 upwards to slide within the chute plate 309, causing the sliding plate 310 to drive the first rack plate 311 to move upwards. Thus, the first rack plate 311 drives the first rotating gear 312 and the second rotating gear 316 to rotate simultaneously through gear meshing. The first rotating gear 312 drives the first rotating wheel 314 to rotate through the rotating rod 313. The first rotating wheel 314 drives the second rotating wheel 315 to rotate through a belt, causing the second rotating wheel 315 to drive the one-way valve 307 to rotate, thereby closing the one-way valve 307. At the same time, the second rotating wheel 315 drives the second rack plate 317 to move horizontally through gear meshing, causing the second rack plate 317 to drive the third rotating gear 318 to rotate. The third rotating gear 318 drives the fixed rod 319 to rotate, and further, the fixed rod 319 rotates to close the ventilation valve 308, preventing the cold air from entering the airbag 304 for inflation and expansion. On the other hand, after the cold air that has absorbed heat is discharged from the exhaust port and enters the exhaust pipe 326, it then enters the air cylinder 324 through the exhaust pipe 326 and pushes the push rod 323, causing the push rod 323 to compress the second spring 325 and extend from the air cylinder 324 to push the push plate 322 to move horizontally. Thus, the push plate 322 pushes the third rack plate 321, and the third rack plate 321 drives the fourth rotating gear 320 to rotate the fixed rod 319 in the reverse direction through gear meshing, causing the fixed rod 319 to rotate in the reverse direction to open the ventilation valve 308. At the same time, after the ventilation valve 308 is opened, the cold air inside the airbag 304 flows into the cold air pipe 302, and the airbag 304 contracts and returns to its original state. The operation process of the sliding plate 310 is opposite to that described above, thereby opening the one-way valve 307, enabling the refrigerator 301 to replenish new cold air into the cold air pipe 302 to absorb heat and flow into the airbag 304 to expand again.
