Description

Technical Field

[0001] This utility model relates to the field of optical fiber communication, specifically to an optical fiber communication device for a conference communication system. Background Technology

[0002] With the popularization of digital conference systems, fiber optic communication devices, as core equipment, directly affect the stability and quality of conferences. Fiber optic communication devices are devices that use light to transmit information in optical fibers. They can be divided into single-mode fiber optic communication devices and multimode fiber optic communication devices. Single-mode fiber optics only allow one mode of light to be transmitted in it, and are suitable for long-distance, high-speed communication, such as long-distance trunk communication and data center interconnection. Multimode fiber optics allow multiple modes of light to be transmitted in it and are often used for short-distance, low-speed communication, such as connections within a local area network.

[0003] Traditional fiber optic communication devices often use a single fan or natural cooling method, which is difficult to cope with the high heat generated by core components such as high-density integrated optical modules and signal processors. Especially when running under high load for a long time, the internal temperature of the device can rise to over 60°C, which leads to an increase in the threshold current of the optical module, aggravated signal attenuation, and in severe cases, equipment failure. To address this, we propose a fiber optic communication device for a conference communication system. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an optical fiber communication device for a conference communication system, which solves the aforementioned problems.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution: a fiber optic communication device for a conference communication system, comprising a housing and a fiber optic communication body, wherein the fiber optic communication body is installed inside the housing, a dustproof and heat dissipation structure is provided on one side of the housing, and a liquid cooling structure is provided inside the housing corresponding to the dustproof and heat dissipation structure, and a set of equidistantly distributed heat dissipation holes are provided on the other side of the housing away from the dustproof and heat dissipation structure on the other side of the fiber optic communication body, and a dustproof net is fixedly connected to each heat dissipation hole on the side of the housing with the heat dissipation holes.

[0006] Preferably, the dustproof and heat dissipation structure includes a square flange, a heat dissipation box, mounting holes, and cooling fans. A mounting hole is provided through one side of the housing, and the heat dissipation box is inserted into the mounting hole. One end of the heat dissipation box is outside the housing, and the square flange is fixedly connected to the open end of the heat dissipation box. The side of the square flange that connects to the heat dissipation box is fitted to the outside of the housing, and the connecting hole of the square flange is fixedly installed on the housing by screws. Multiple cooling fans are snapped together between the open sides of the heat dissipation box.

[0007] Preferably, the dustproof and heat dissipation structure further includes silicone sheets and ventilation holes. Multiple silicone sheets are fixedly connected to each heat dissipation box corresponding to the top and bottom surfaces of the housing. Adjacent silicone sheets are bonded to each other and cover the inside and outside of the heat dissipation box. The silicone sheets are located away from the opening of the heat dissipation box between the cooling fan and the heat dissipation box. A row of equidistant ventilation holes is opened through the outer surface of the heat dissipation box corresponding to the top and bottom surfaces of the housing. The ventilation holes are located away from the cooling fan between the silicone sheets and the heat dissipation box.

[0008] Preferably, a cover plate is snapped between the open sides of the heat sink box, and a set of equidistant heat dissipation holes are opened through the side of the cover plate corresponding to the heat dissipation fan. The heat dissipation fan is located inside the cover plate and the heat sink box.

[0009] Preferably, the liquid cooling structure includes a heat absorption box, through holes, and condenser tubes. The heat absorption box is snapped into the heat dissipation box, with one side of the heat absorption box fitting against the opening of the heat dissipation box. Multiple sets of through holes are arranged in a matrix and equidistantly on the side of the heat absorption box away from the heat dissipation box. Each set of through holes includes two through holes, which are respectively close to the two sides of the heat dissipation box. The condenser tubes are C-shaped tubular structures, with both ends of the condenser tubes fixedly connected to the heat absorption box, and each end of a condenser tube corresponds to a set of through holes. The heat absorption box and condenser tubes are located away from the silicone sheet between the ventilation holes and the heat dissipation box.

[0010] Preferably, the liquid cooling structure includes a square hole and a one-way waterproof and breathable membrane. The outer cylindrical surface of the one-way waterproof and breathable membrane is fixedly connected to each of the through holes. The water-blocking side of the one-way waterproof and breathable membrane corresponds to the interior of the heat absorption box. A square hole is provided through the side of the heat dissipation box opposite to the opening, and the square hole connects the heat absorption box and the interior of the shell.

[0011] Compared with the prior art, the present invention provides an optical fiber communication device for a conference communication system, which has the following advantages:

[0012] 1. The fiber optic communication device of this conference communication system adopts a heat dissipation method that combines liquid cooling structure with cooling fan, which effectively solves the problem of insufficient heat dissipation capacity of traditional devices. In the liquid cooling structure, the fatty acid coolant in the heat absorption box has a low phase change temperature, which can quickly absorb heat and vaporize when the equipment temperature rises. After being cooled and liquefied through the condenser, it flows back to form a closed loop for continuous heat dissipation. At the same time, when the temperature exceeds the preset value, the cooling fan starts and works in conjunction with the liquid cooling system to accelerate heat conduction and dissipation.

[0013] 2. Regarding dust prevention, the fiber optic communication device of this conference communication system features a silicone sheet that remains closed when the cooling fan is not running, effectively covering the area connecting the heat sink and the housing to prevent dust from entering. When the fan starts, the airflow pressure causes the silicone sheet to deform and open, forming a ventilation channel that ensures both heat dissipation and dust prevention. In terms of maintenance, the heat sink is fixed to the housing via a square flange, allowing for quick and easy disassembly. This enables cleaning and inspection of internal components such as the fan and condenser pipes. The cover plate snaps into the opening of the heat sink, facilitating individual maintenance of the cooling fan. Attached Figure Description

[0023] Furthermore, the dustproof and heat dissipation structure includes a square flange 2, a heat dissipation box 7, mounting holes 8, and cooling fans 4. A mounting hole 8 is provided through one side of the housing 1, into which the heat dissipation box 7 is inserted and connected.

The side of the square flange 2 connecting to the heat dissipation box 7 is flush with the outside of the housing 1, and the connecting holes of the square flange 2 are fixedly installed on the housing 1 by screws. Multiple equally spaced cooling fans 4 are snap-fitted between the open sides of the heat dissipation box 7. The heat dissipation box 7 is used to install the dustproof and heat dissipation structure and the liquid cooling structure. The square flange 2 is used to connect the heat dissipation box 7 to the housing 1 for easy disassembly. The mounting holes 8 are used to insert the heat dissipation box 7, and the cooling fans 4 are used to generate airflow to dissipate heat from the housing 1 and the fiber optic communication unit 6.

[0024] Furthermore, the dustproof and heat dissipation structure also includes silicone sheets 11 and ventilation holes 12. Multiple silicone sheets 11 are fixedly connected to the top and bottom surfaces of the heat dissipation box 7 corresponding to the shell 1. Adjacent silicone sheets 11 are bonded together and cover the inside and outside of the heat dissipation box 7. The silicone sheets 11 are located away from the opening of the heat dissipation box 7 between the cooling fan 4 and the heat dissipation box 7. A row of equidistant ventilation holes 12 are opened through the outer surface of the heat dissipation box 7 corresponding to the top and bottom surfaces of the shell 1. The ventilation holes 12 are located away from the cooling fan 4 between the silicone sheets 11 and the heat dissipation box 7. The silicone sheets 11 are used for dust prevention. When the cooling fan 4 does not generate airflow, the silicone sheets 11 cover the heat dissipation box 7 and the inside in their original state to prevent dust from entering. When the cooling fan 4 generates airflow, the silicone sheets 11 change shape to introduce airflow into the heat dissipation box 7 and the interior of the shell 1. The ventilation holes 12 are used to connect the heat dissipation box 7 and the shell 1.

[0025] Furthermore, a cover plate 3 is snapped between the open side of the heat sink 7 and the side of the cover plate 3 corresponding to the heat sink fan 4. A set of equidistant heat dissipation holes 5 are opened through the cover plate 3. The heat sink fan 4 is inside the cover plate 3 and the heat sink 7. The cover plate 3 is used to seal one end of the opening of the heat sink 7 and limit the heat sink fan 4. The heat dissipation holes 5 are used for ventilation.

[0026] Furthermore, the liquid cooling structure includes a heat absorption box 9, through holes 13, and condenser tubes 10. The heat absorption box 9 is snapped into the heat sink 7, with one side of the heat absorption box 9 fitting against the opening of the heat sink 7. Multiple sets of through holes 13 are arranged in a matrix and are equidistantly distributed on the side of the heat absorption box 9 away from the heat sink 7. Each set of through holes 13 includes two through holes 13, which are respectively close to the two sides of the heat sink 7. The condenser tubes 10 are C-shaped tubular structures, with both ends of the condenser tubes 10 fixedly connected to the heat absorption box 9, and each end of a condenser tube 10 corresponds to a set of through holes 13. The heat absorption box 9 and the condenser tubes 10 are located away from the silicone sheet 11 between the ventilation hole 12 and the heat sink 7. The heat absorption box 9 is used to hold the coolant, which is a fatty acid-based cooling material. Such materials and their derivatives usually have a low phase change temperature. The through holes 13 are used to install the condenser tubes 10.

[0027] Furthermore, the liquid cooling structure includes a square hole 15 and a one-way waterproof and breathable membrane 14. The outer cylindrical surface of the one-way waterproof and breathable membrane 14 is fixedly connected to the through hole 13. The water-blocking side of the one-way waterproof and breathable membrane 14 corresponds to the inside of the heat absorption box 9. The side opposite the opening of the heat dissipation box 7 has a square hole 15 through it. The square hole 15 connects the heat absorption box 9 and the inside of the shell 1. The one-way waterproof and breathable membrane 14 is a thin film material with special functions, which allows gas (such as air and water vapor) to diffuse from one side of the membrane to the other side, while preventing liquid (such as water) from permeating in the opposite direction from the other side. The one-way waterproof and breathable membrane 14 is used to block the heat absorption box 9 and the condenser tube 10. The condenser tube 10 stores gaseous coolant. When the shell 1 is stably raised, the coolant in the heat absorption box 9 absorbs heat and vaporizes, moving towards the condenser tube 10 with a lower temperature. It is cooled and liquefied in the condenser tube 10. The overall fiber optic communication device is rotated periodically to turn the condenser tube 10 upward, so that the coolant in the condenser tube 10 flows back into the heat absorption box 9.

[0028] Structural Description:

[0029] Housing 1: Housing 1 is the outer shell of the device, usually designed as a cuboid or cube structure. It is mainly used to protect the internal fiber optic communication body 6 and other components. One side of housing 1 is equipped with a dustproof and heat dissipation structure, and the other side has a heat dissipation hole 16 for heat dissipation and air circulation, so as to ensure that the internal temperature of the device is kept within a reasonable range.

[0030] Square flange 2: Square flange 2 is a square or rectangular connecting plate with screw holes for fixing the heat sink 7 to the housing 1.

[0032] Cooling fan 4: Cooling fan 4 is a round or square fan module installed inside the heat sink 7. Its main function is to generate airflow to force the housing 1 and the fiber optic communication body 6 to be cooled by air, thereby reducing the internal temperature of the device.

[0033] Heat dissipation hole 5: Heat dissipation hole 5 is a group of equally spaced circular or square holes located on the cover plate 3. Their function is to allow airflow to pass through the cover plate 3 into the heat dissipation box 7, and then into the interior of the shell 1, thereby enhancing the heat dissipation effect.

[0034] Fiber Optic Communication Body 6: The fiber optic communication body 6 is the core part of the equipment. It is usually composed of core components such as optical modules and signal processors. It adopts a modular design. Its function is to realize fiber optic communication, but it will generate a lot of heat during operation, which needs to be cooled by a heat dissipation system.

[0035] Heat sink 7: Heat sink 7 is a cuboid or cube structure with a hollow interior, used to install cooling fan 4, liquid cooling structure and silicone pad 11. Its main function is to centrally manage the heat dissipation components and ensure the efficient operation of the heat dissipation system.

[0036] Mounting hole 8: Mounting hole 8 is a round or square opening located on one side of housing 1, used to insert heat sink 7. Its function is to facilitate the installation and removal of heat sink 7, while ensuring a stable connection between heat sink 7 and housing 1.

[0037] Heat Absorber 9: The heat absorber 9 is a cuboid or cubic structure filled with fatty acid-based coolant. Its function is to absorb the heat generated by the optical fiber communication body 6 and dissipate heat through the phase change of the coolant to reduce the internal temperature of the equipment.

[0038] Condenser 10: Condenser 10 is a C-shaped tubular structure connected to heat absorption boxes 9 at both ends. Its function is to cool the gaseous coolant into a liquid state, realize the recycling of coolant, and ensure the continuous and efficient operation of the heat dissipation system.

[0039] Silicone sheet 11: Silicone sheet 11 is a thin sheet structure that covers the ventilation holes 12 of the heat sink 7. Its function is to prevent dust. When the cooling fan 4 is not working, the silicone sheet 11 covers the ventilation holes 12 to prevent dust from entering. When the fan is working, the silicone sheet 11 deforms to allow airflow.

[0040] Ventilation holes 12: Ventilation holes 12 are a row of equally spaced circular or square holes located on the outer surface of the heat sink 7. Their function is to connect the heat sink 7 and the interior of the shell 1, allowing airflow to enter the shell 1 for heat dissipation.

[0041] Through holes 13: Through holes 13 are a matrix of circular holes located on one side of the heat absorption box 9. Their function is to install condenser tubes 10 and allow gaseous coolant to pass through, so as to realize the circulation of coolant.

[0042] One-way waterproof and breathable membrane 14: One-way waterproof and breathable membrane 14 is a thin film structure that covers the through holes 13.

[0043] Square hole 15: Square hole 15 is a square opening located on one side of the heat sink 7, connecting the heat absorption box 9 and the interior of the shell 1. Its function is to form a circulation channel for the coolant and ensure the continuous operation of the heat dissipation system.

[0044] Heat dissipation hole 2 16: Heat dissipation hole 2 16 is a group of equally spaced circular or square holes located on one side of the housing 1. Their function is to exhaust hot air inside the housing 1 and enhance the heat dissipation effect.

[0045] Dustproof net 17: Dustproof net 17 is a mesh structure that covers the heat dissipation hole 16. Its function is to filter dust in the outside air, prevent dust from entering the equipment, and ensure the long-term stable operation of the equipment.

[0046] Working Principle: The fiber optic communication unit 6 (such as optical modules, signal processors, etc.) generates heat during operation, causing the internal temperature of the housing 1 to rise. The heat absorption box 9 is filled with a fatty acid-based coolant with a low phase change temperature (e.g., 30-50℃). When the temperature inside the housing 1 exceeds a threshold, the coolant absorbs heat and vaporizes, entering the condenser tube 10 through the one-way waterproof and breathable membrane 14. The condenser tube 10 has a C-shaped structure and is distributed outside the heat dissipation box 7. It utilizes ambient temperature (e.g., airflow from a conference room air conditioner) to cool the gaseous coolant, causing it to liquefy and flow back to the heat absorption box 9. The square hole 15 connects the heat absorption box 9 to the inside of the housing 1, forming a closed loop. Periodically rotating the equipment to face the condenser tube 10 upwards accelerates the gravity return of the liquefied coolant. When the equipment temperature sensor detects that the temperature inside the housing 1 exceeds a preset value (e.g., 45℃), the cooling fan 4 starts, generating airflow. The airflow enters the heat dissipation box 7 through the heat dissipation hole 5, and then enters the inside of the housing 1 through the ventilation hole 12, working in conjunction with the liquid cooling system to remove heat. Silicone sheets... When fan 4 is not running, silicone sheet 11 is closed, covering the area connecting heat sink 7 and housing 1 to prevent dust from entering. When fan 4 is running, the airflow pressure causes silicone sheet 11 to deform and open, forming a ventilation channel to ensure effective airflow into housing 1. Dust filter 17 covers heat dissipation hole 2 16 to further filter dust in the outside air and prevent it from entering the equipment. The liquid cooling system reduces the temperature of the core area through phase change heat dissipation. At the same time, fan 4 drives airflow across the surface of fiber optic communication body 6, accelerating heat conduction to the inner wall of housing 1. Heat dissipation hole 2 16 on the other side of housing 1 works with dust filter 17 to expel hot air from the equipment. Heat sink 7 is fixed to housing 1 by square flange 2, which can be quickly disassembled for maintenance or component replacement, cleaning of fan 4, inspection of condenser pipe 10, etc. Cover plate 3 is snapped into the opening of heat sink 7 for easy independent maintenance of cooling fan 4. Fatty acid coolant does not need to be replaced regularly. One-way waterproof and breathable membrane 14 ensures that coolant circulates only in a gaseous state, avoiding leakage risk.
