Abstract

The present invention discloses a high-density heat dissipation fin radiator for a communication device, which includes a radiator body, a heat dissipation frame, an elastic dust removal component, and a fan drive component. The present invention can achieve that an elastic dust removal component is installed at the bottom of each second heat dissipation fin, and a support member is fixedly installed at the bottom of every other second heat dissipation fin.

The support member is heated and expands, pushing the plurality of second heat dissipation fins and the heat dissipation frame upward. When the temperature returns and decreases, the support member can automatically reset, squeezing the bottom connecting pipe of the elastic dust removal component, and the air in the bottom connecting pipe can be squeezed into the cylindrical dust removal box and discharged through the openings at the front and rear ends thereof.

Description

Technical Field

[0001] The present invention relates to the field of radiators, and more particularly, to a high-density heat dissipation fin radiator for communication devices. Background Art

[0002] For communication devices, especially those that require efficient heat dissipation, using a high-density heat dissipation fin radiator is a common and effective option. Such radiators are typically used to manage and disperse the heat generated inside the device, ensuring that the device maintains a stable temperature during long-term operation. The high-density heat dissipation fin design can provide a larger surface area, effectively increasing the efficiency of heat transfer. This design helps to more quickly conduct and dissipate the heat from the device. High-density fin radiators are usually designed to be compact, capable of providing a larger heat dissipation surface area within a limited space. High-density heat dissipation fin radiators are typically made of some high-quality heat-conducting materials. Aluminum has a relatively high thermal conductivity, enabling the aluminum plate radiator to quickly conduct the heat from the heat source to the heat dissipation surface and rapidly dissipate it into the air.

[0003] The radiators used in existing communication devices are all sealed inside the communication devices. The radiator absorbs the heat of the internal components of the communication device and dissipates it. Therefore, heat dissipation holes need to be provided on the surface of the communication device to assist the radiator in dissipating heat, which in turn causes the radiator to come into contact with the external air, resulting in dust in the air adhering to the fins of the radiator. The long-term accumulation of dust affects the heat dissipation effect of the radiator.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a high-density heat dissipation fin radiator for communication devices. Summary of the Invention

[0005] The purpose of the present invention is to provide a high-density heat dissipation fin radiator for communication devices to solve the above problems.

[0006] To achieve the above purpose, the technical solution provided by an embodiment of the present invention is as follows:

A movable insertion rod is fixedly installed at the lower end of the second limiting piece. The movable insertion rod is movably inserted into the fixed sleeve, and the shapes of the movable insertion rod and the fixed sleeve are adapted to each other.

[0012] As a further improvement of the present invention, multiple said elastic dust removal components each include a bottom connecting pipe and a cylindrical dust removal box. The bottom connecting pipe is installed at the upper end of the heat conduction frame by a fixed connection method, and the bottom connecting pipe is located between multiple first heat dissipation fins. The cylindrical dust removal box is installed at the front and rear ends of the bottom connecting pipe by a fixed connection method, and the bottom connecting pipe is in communication with the inside of the cylindrical dust removal box. The materials of both the bottom connecting pipe and the cylindrical dust removal box are silicone rubber, and the height of the cylindrical dust removal box is the same as that of the first heat dissipation fins.

[0013] As a further improvement of the present invention, openings are provided at the front and rear ends of multiple said cylindrical dust removal boxes. The shape of the openings is longitudinally elongated. Fixed plates are fixedly embedded on both sides inside the cylindrical dust removal box, and the material of the fixed plates is aluminum plate.

[0014] As a further improvement of the present invention, the fan drive assembly includes a mounting seat, a servo motor, and a third sprocket. The two mounting seats are respectively installed at the middle parts on the right sides of the heat conduction frame and the heat dissipation frame by a fixed connection method. The servo motor is installed at the lower end of the lower mounting seat by a fixed connection method. The two third sprockets are both installed at the adjacent ends of the mounting seats by a rotational connection method, and the output end of the servo motor is fixedly connected to the lower third sprocket.

[0015] As a further improvement of the present invention, rectangular holes are provided on the right sides of the heat conduction frame and the heat dissipation frame.

[0017] Compared with the prior art, the advantages of the present invention are as follows:

[0018] (1) This solution can be implemented by installing an elastic dust removal component at the bottom of each second heat dissipation fin, and a support is fixedly installed at the bottom of every other second heat dissipation fin. The material of this support is shape memory alloy. When the surface temperature of the heat conduction frame is high, the support heats up and expands, pushing the heat dissipation frame and the plurality of second heat dissipation fins upward, enabling more contact between the surface of the first heat dissipation fin and air to assist in heat dissipation. When the temperature returns and decreases, the support can automatically reset, squeezing the bottom connecting pipe of the elastic dust removal component, squeezing the air in the bottom connecting pipe into the cylindrical dust removal boxes at its front and rear ends, and discharging the air through the openings at its front and rear ends. The discharged air can blow away the dust on the surfaces of the first heat dissipation fin and the second heat dissipation fin. The setting of this structure can accelerate the heat dissipation speed of the radiator, and can automatically clean the surface of the radiator while dissipating heat, effectively improving the functionality of the radiator and strengthening the protection of the radiator.

[0019] (2) This solution can also be implemented by installing a fan drive component in the middle of the right side of the heat dissipation frame and the heat conduction frame. In the default state, the rotation of the servo motor on the fan drive component can drive the first heat dissipation fan in the lower heat conduction frame to rotate. However, when the temperature inside the radiator is too high, the support pushes the heat dissipation frame upward, and the heat dissipation frame synchronously drives the telescopic rod upward, so that the semi-circular block on the outside of the telescopic rod is clamped into the gaps between the plurality of limit strips in the fixed limit cylinder, clamping the telescopic rod and the fixed limit cylinder. Furthermore, when the servo motor drives the fixed limit cylinder to rotate, the telescopic rod can be driven to rotate synchronously, enabling the upper chain to drive the second heat dissipation fan in the heat dissipation frame to rotate synchronously. This structure can accelerate the internal heat dissipation of the radiator and reduce energy consumption through a mechanical linkage structure. Description of the Drawings

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1:

[0031] Please refer to Figure 1-7 , a high-density heat dissipation fin radiator for a communication device, including a radiator body 1, a heat dissipation frame 15, an elastic dust removal component 17 and a fan drive component 18. The radiator body 1 includes a metal substrate 11 and a heat conduction frame 12. The heat conduction frame 12 is installed at the upper end of the metal substrate 11 by a fixed connection method. A plurality of first heat dissipation fins 14 arranged in a horizontal array are fixedly installed at the upper end of the heat conduction frame 12. A plurality of heat dissipation holes 121 arranged longitudinally are provided on both sides of the heat conduction frame 12. A plurality of side heat dissipation fins 13 arranged longitudinally are fixedly installed on both sides of the heat conduction frame 12. The side heat dissipation fins 13 and the heat dissipation holes 121 are arranged in an alternating manner. A plurality of first rotating rods 122 arranged in a horizontal array are rotatably installed inside the heat conduction frame 12. A first heat dissipation fan 123 is fixedly installed in the middle of the outer side of the first rotating rod 122. A first sprocket 124 is fixedly installed at the upper end of the outer side of the first rotating rod 122;

[0032] Specifically, a metal substrate 11 is installed at the bottom of the radiator body 1 for contacting parts inside the communication device, absorbing the heat inside the parts, and blowing the heat into a plurality of first heat dissipation fins 14 at the top by the rotation of the first heat dissipation fan 123. The highly sealed first heat dissipation fins 14 and the side heat dissipation fins 13 on both sides of the heat conduction frame 12 help with heat dissipation, improving the heat dissipation efficiency of the radiator body 1.

[0033] A plurality of second heat dissipation fins 16 are fixedly installed at the lower end of the heat dissipation frame 15. The second heat dissipation fins 16 are fixedly distributed at the bottom of the heat dissipation frame 15 through a horizontal array, and the second heat dissipation fins 16 are inserted between a plurality of first heat dissipation fins 14. The plurality of second heat dissipation fins 16 and the plurality of first heat dissipation fins 14 are arranged in an alternating manner. The length of the second heat dissipation fins 16 is less than the length of the first heat dissipation fins 14. A heat dissipation filter screen 153 is arranged at the top of the heat dissipation frame 15. A plurality of second rotating rods 154 distributed in a horizontal array are rotatably installed inside the heat dissipation frame 15. A second heat dissipation fan 155 is fixedly installed in the middle on the outer side of the second rotating rod 154. A second sprocket 156 is fixedly installed at the lower end on the outer side of the second rotating rod 154.

[0034] First limiting pieces 141 are fixedly installed at the front and rear ends on the left side of the left first heat dissipation fin 14. A fixed sleeve 142 is fixedly installed at the upper end of the first limiting piece 141. Second limiting pieces 151 are fixedly installed at the front and rear ends on the left side of the heat dissipation frame 15. A movable insertion rod 152 is fixedly installed at the lower end of the second limiting piece 151. The movable insertion rod 152 is movably inserted into the fixed sleeve 142, and the shape of the movable insertion rod 152 is adapted to that of the fixed sleeve 142.

[0035] Specifically, by arranging second heat dissipation fins 16 at the side ends of a plurality of first heat dissipation fins 14, the number of heat dissipation fins is increased, thereby increasing the heat dissipation area, helping the radiator body 1 to conduct and dissipate heat, and installing a heat dissipation frame 15 at the upper end of the second heat dissipation fins 16 can further dissipate heat from the second heat dissipation fins 16.

[0036] There are multiple elastic dust removal components 17, which are fixedly connected to the upper end of the heat-conducting frame 12, and the elastic dust removal components 17 are located between the multiple first heat dissipation fins 14. The elastic dust removal components 17 are located at the lower ends of the multiple second heat dissipation fins 16. A support member 19 is provided in the inner middle of each elastic dust removal component 17. The support member 19 is fixedly connected to the second heat dissipation fin 16 and the heat-conducting frame 12, and the inner middle of the elastic dust removal component 17 with the support member 19 installed on the inner side is sealed. The material of the support member 19 is a shape memory alloy. The multiple elastic dust removal components 17 include a bottom connecting pipe 171 and a cylindrical dust removal box 172. The bottom connecting pipe 171 is connected to the second heat dissipation fin 16 and the heat-conducting frame 12. It is fixedly connected and installed at the upper end of the heat-conducting frame 12, and the bottom connecting tube 171 is located between the multiple first heat dissipation fins 14, and the cylindrical dust removal box 172 is fixedly connected and installed at the front and rear ends of the bottom connecting tube 171, and the bottom connecting tube 171 is connected to the inside of the cylindrical dust removal box 172, and the bottom connecting tube 171 and the cylindrical dust removal box 172 are made of silicone rubber. The height of the cylindrical dust removal box 172 is consistent with the height of the first heat dissipation fins 14, and the front and rear ends of the multiple cylindrical dust removal boxes 172 are provided with openings 1721, and the shape of the openings 1721 is a longitudinal strip, and shaping plates 1722 are fixedly embedded on both sides of the cylindrical dust removal box 172, and the shaping plates 1722 are made of aluminum plates.

[0037] Specifically, by installing a support member 19 between the plurality of first heat sink fins 14 to support and limit the second heat sink fins 16, when the temperature inside the heat conduction frame 12 is too high, the support member 19 made of shape memory alloy can be stretched in a high temperature environment to push the second heat sink fins 16 to move upward, so that a large amount of external air can enter the first heat sink fins 14 and the second heat sink fins 16 when they are staggered and overlapped, thereby increasing the contact area between the first heat sink fins 14 and the second heat sink fins 16 and the normal temperature air, improving the heat dissipation effect of the first heat sink fins 14 and the second heat sink fins 16, and smoothly lowering the temperature of the heat conduction frame 12. After the temperature reaches 0, the support member 19 automatically resets and drives the second heat dissipation fins 16 and the heat dissipation frame 15 on the top thereof to move downward and reset. While moving downward, the second heat dissipation fins 16 can squeeze the bottom connecting tube 171 at the bottom thereof, and squeeze the air in the bottom connecting tube 171 into the cylindrical dust removal box 172 at the front and rear ends thereof. Under the influence of pressure, the openings 1721 at the front and rear ends of the cylindrical dust removal box 172 are propped open to squeeze the air outward, and the dust on the surface of the first heat dissipation fins 14 can be automatically cleaned. The arrangement of this structure can effectively improve the functionality of the radiator body 1 and strengthen the maintenance of the radiator body 1.

[0038] The fan drive assembly 18 is installed on the right sides of the heat conduction frame 12 and the heat dissipation frame 15 by a fixed connection method. The fan drive assembly 18 includes a mounting base 181, a servo motor 182, and a third sprocket 183. The two mounting bases 181 are respectively installed on the middle parts of the right sides of the heat conduction frame 12 and the heat dissipation frame 15 by a fixed connection method. The servo motor 182 is installed at the lower end of the lower mounting base 181 by a fixed connection method. The two third sprockets 183 are both installed at the adjacent ends of the mounting base 181 by a rotational connection method. The output end of the servo motor 182 is fixedly connected to the lower third sprocket 183. Rectangular holes are provided on the right sides of the heat conduction frame 12 and the heat dissipation frame 15. Chains 184 are meshed and installed on the outer sides of multiple first sprockets 124 and the upper third sprocket 183 and multiple second sprockets 156 and the lower third sprocket 183. The chain 184 passes through the rectangular holes. The upper third sprocket 183 and the second sprocket 156 are at the same height. The lower third sprocket 183 and the first sprocket 124 are at the same height;

[0039] A telescopic rod 186 is fixedly installed at the lower end of the upper third sprocket 183. Semi-circular clamping blocks 1861 are fixedly installed at the four outer ends of the telescopic rod 186, and the semi-circular clamping blocks 1861 are located at the lower outer end position of the telescopic rod 186. A fixed limiting cylinder 185 is fixedly installed at the upper end of the lower third sprocket 183. The telescopic rod 186 is inserted into the fixed limiting cylinder 185. A circular cavity 1851 is provided at the upper end inside the fixed limiting cylinder 185. Limiting strips 1852 are fixedly installed at the four corners of the upper end inside the circular cavity 1851.

[0040] Specifically, in the default state, the temperature inside the radiator body 1 is normal. The second heat dissipation fins 16 are inserted between multiple first heat dissipation fins 14, and the heat dissipation frame 15 is located below. The telescopic rod 186 on the right side of the heat dissipation frame 15 is inserted into the fixed limiting cylinder 185, and multiple semi-circular clamping blocks 1861 on the outer side of the telescopic rod 186 are located below the limiting strip 1852 and are offset from the limiting strip 1852. Starting the servo motor 182 can drive the lower third sprocket 183, the lower chain 184, and multiple first heat dissipation fans 123 to rotate, and the first heat dissipation fans 123 in the heat conduction frame 12 assist the radiator body 1 in heat dissipation. However, when the parts at the bottom of the metal substrate 11 generate a large amount of heat, the temperature inside the heat conduction frame 12 is high, the support member 19 expands due to heat, pushes the second heat dissipation fins 16 and the heat dissipation frame 15 upward. At the same time, the heat dissipation frame 15 drives the mounting seat 181, the third sprocket 183, and the telescopic rod 186 on its right side upward. While the telescopic rod 186 is moving upward, the fixed limiting cylinder 185 is still rotating, and the semi-circular clamping blocks 1861 can be inserted between multiple limiting strips 1852 in the gap of the rotation of the fixed limiting cylinder 185. The semi-circular clamping blocks 1861 are clamped with the limiting strips 1852, so that the rotation of the fixed limiting cylinder 185 can simultaneously drive the telescopic rod 186 and the upper third sprocket 183 to rotate, and drive multiple second heat dissipation fans 155 in the heat dissipation frame 15 to rotate. In the case of high temperature inside the radiator body 1, the fan drive assembly 18 can simultaneously drive the second heat dissipation fans 155 to rotate for heat conduction, improve the heat dissipation effect of the radiator body 1, accelerate the heat dissipation speed of the radiator body 1, and strengthen the protection of the communication device.

[0041] The working principle of the present invention is as follows: First, the radiator body 1 is fixedly installed in the communication device, and the side with the metal substrate 11 is attached to the surface of the part to be cooled. The radiator body 1 is connected to the power supply. In the default state, the temperature inside the radiator body 1 is normal. The second heat dissipation fins 16 are inserted between multiple first heat dissipation fins 14, and the heat dissipation frame 15 is located below. The telescopic rod 186 on the right side of the heat dissipation frame 15 is inserted into the fixed limiting cylinder 185, and multiple semi-circular clamping blocks 1861 on the outer side of the telescopic rod 186 are located below the limiting strip 1852 and are misaligned with the limiting strip 1852. When the servo motor 182 is started, it can drive the lower third sprocket 183, the lower chain 184, and multiple first heat dissipation fans 123 to rotate, and the first heat dissipation fans 123 in the heat conduction frame 12 assist the radiator body 1 in heat dissipation; however, when the heat of the part at the bottom of the metal substrate 11 is large, the inside of the heat conduction frame 12 is at a high temperature, the support member 19 expands and stretches, pushing the second heat dissipation fins 16 and the heat dissipation frame 15 upward. At the same time, the heat dissipation frame 15 drives the mounting seat 181, the third sprocket 183, and the telescopic rod 186 on its right side upward. While the telescopic rod 186 is moving upward, the fixed limiting cylinder 185 is still rotating, and the semi-circular clamping blocks 1861 can be caught between multiple limiting strips 1852 in the gap of the rotation of the fixed limiting cylinder 185. The semi-circular clamping blocks 1861 are clamped with the limiting strips 1852, so that the rotation of the fixed limiting cylinder 185 can simultaneously drive the telescopic rod 186 and the upper third sprocket 183 to rotate, and drive multiple second heat dissipation fans 155 in the heat dissipation frame 15 to rotate, so that when the inside of the radiator body 1 is at a high temperature, the fan drive assembly 18 can simultaneously drive the second heat dissipation fans 155 to rotate for heat conduction, improving the heat dissipation effect of the radiator body 1;

[0042] After the heat conduction frame 12 cools down smoothly, the support member 19 automatically resets, driving the second heat dissipation fins 16 and the heat dissipation frame 15 at its top to move downward and reset. While the second heat dissipation fins 16 are moving downward, they can squeeze the bottom connecting pipe 171 at their bottom, squeezing the air in the bottom connecting pipe 171 into the cylindrical dust removal boxes 172 at its front and rear ends. Affected by the pressure, the openings 1721 at the front and rear ends of the cylindrical dust removal boxes 172 are opened, and the air is squeezed outwards, which can automatically clean the dust on the surface of the first heat dissipation fins 14. The setting of this structure can effectively improve the functionality of the radiator body 1 and strengthen the maintenance of the radiator body 1.
