Description

Technical Field

[0001] This invention relates to the field of communication cabinet cooling technology, and more specifically, to an outdoor information communication cabinet with dual air and water cooling. Background Technology

[0002] A communication cabinet is a housing made of metal or non-metal materials used to house communication equipment. It provides an outdoor physical working environment and security system for wireless communication sites or wired network sites. To improve heat dissipation, existing communication cabinets typically couple water-cooling and air-cooling systems within the housing. The water-cooling structure is responsible for precise temperature control of the core high-temperature areas, using circulating coolant to remove heat generated by core components (such as the baseband processing unit) and prevent localized overheating. The air-cooling structure enhances heat flow and exchange throughout the housing, accelerating the expulsion of hot air from the cabinet while also improving the heat exchange efficiency between the coolant and air by flushing the surface of the water-cooling pipes with airflow.

[0003] As the heat exchange time of the water-cooled structure increases, the hot air in the fin gaps exchanges heat with the outside environment. Although the dustproof mesh can isolate some outdoor dust, the air still carries small dust particles, lint, and other substances. When these particles flow through the fin gaps, they gradually form lint-like dust accumulation. When air flows through this area again, the flow rate will decrease, thereby weakening the heat dissipation effect of the water-cooled structure.

[0004] In view of this, we propose an outdoor information communication cabinet with dual air and water cooling to improve the above-mentioned shortcomings. Summary of the Invention

[0005] This invention provides an outdoor information communication cabinet with dual air and water cooling, which solves the problem that the heat dissipation effect is weakened due to dust accumulation between the fins in the existing water-cooled structure.

[0006] To achieve the above objectives, the dual-cooling outdoor information communication cabinet includes a housing located on top of the base, a protective cover on the outside of the housing, a back panel installed inside one of the side panels of the housing, and a baseband processing unit that generates a large amount of heat electrically connected to the back panel. A water-cooling head for heat conduction is fixedly attached to the side of the baseband processing unit away from the back plate. A radiator tube is sealed and connected to the side of the water-cooling head away from the baseband processing unit. Heat dissipation fins are provided below the radiator tube. Multiple sliding bolts are fitted on the radiator tube. A toggle blade is rotatably connected to the side plate opposite to the side plate connected to the back plate. The sliding bolts are used to transfer heat from the radiator tubes to the heat dissipation fins to accelerate heat dissipation. When the agitator starts to rotate, it pushes multiple sliding bolts to move, thereby changing the relative position of the heat dissipation fins and the sliding bolts, and at the same time changing the contact position between the sliding bolts and the radiator tubes. The agitator can also scrape away the dust accumulated in the gaps between the heat dissipation fins.

[0007] In the above technical solution, the baseband processing unit on the backplate generates a large amount of heat. The water-cooling head, which is directly attached to the baseband processing unit, transfers the heat to the radiator tubes. The radiator tubes then conduct the heat to the heat dissipation fins via sliding bolts, thereby accelerating heat dissipation. Finally, the fan located at the top of the housing extracts the hot air from the housing while simultaneously introducing cool air from the outside. During this process, dust carried by the air entering the housing from the outside gradually accumulates in the gaps between the heat dissipation fins. The continuously rotating blades change the contact position between the sliding bolts and the radiator tubes, preventing localized thermal stress concentration on the radiator tubes. At the same time, the blades, passing through the gaps between the heat dissipation fins, scrape away the accumulated dust, preventing it from affecting the heat dissipation effect of the heat dissipation fins.

[0008] Based on this, the water cooling head is made of a high thermal conductivity metal, and a liquid storage chamber is sealed on the side of the water cooling head away from the baseband processing unit, which is used to store coolant.

[0009] Furthermore, a drive blade is rotatably connected to the side of the liquid storage chamber away from the water cooling head. The drive blade is driven by a motor. A pair of radiator interfaces are connected to the liquid storage chamber. The drive blade is used to drive the coolant to flow between the two radiator interfaces.

[0010] In another technical solution, the radiator pipes are distributed horizontally, and both ends of the radiator pipes are connected to two radiator interfaces to increase the path through which the heated coolant flows.

[0011] Two limiting rings are fixedly connected to the outer wall of the radiator at the two ends of the sliding bolt that are far apart from each other, and the sliding bolt is slidably connected to the outer wall of the radiator.

[0012] Based on the above, the two limiting rings are distributed along the sliding direction of the sliding bolt. A spring is provided between the two ends of the sliding bolt that are furthest apart and the limiting rings. The two ends of the spring are fixedly connected to the spring and the sliding bolt respectively, and the spring is slidably sleeved on the outer wall of the cooling pipe. This technical solution allows the sliding bolt to change its contact position, making the heat distribution of the cooling coil more uniform and dispersing thermal stress throughout the entire coil body.

[0013] In addition, a mounting plate is fixedly connected to the heat dissipation fins on the side away from the actuating blade. The top of the mounting plate is fixedly connected to multiple sliding bolts to conduct the heat from the multiple sliding bolts to the heat dissipation fins.

[0014] The agitator blade has a main shaft at its center for driving its rotation. The main shaft is rotatably connected to the side plate of the housing. The main shaft is driven by a motor, and the motor that drives the main shaft to rotate is located on the outside of the housing.

[0015] The edge of the agitator blade is covered with a flexible protective layer made of rubber, which is used to scrape away the dust accumulated in the gaps between the heat sink fins while preventing scratches on the sidewalls of the heat sink fins.

[0016] When the spring is in its natural state, the distance between the main shaft and the mounting plate is less than the length of the actuating blade.

[0017] Based on the above description, the beneficial effects of the present invention compared with the prior art are as follows: By continuously sweeping the mounting plate with the agitator blades, the sliding bolts slide along the outer wall of the radiator tubes, thereby changing the relative position of the heat dissipation fins and the radiator tubes. This prevents thermal stress concentration caused by the radiator tubes maintaining a constant contact position with the sliding bolts. At the same time, the agitator blades, which are continuously inserted into the gaps between the heat dissipation fins, scrape away accumulated dust in the gaps, preventing it from affecting the heat exchange efficiency between the heat dissipation fins and the airflow delivered by the exhaust fan.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] In the existing technology, as the heat exchange time of the water-cooled structure increases, the hot air in the fin gaps exchanges heat with the outside environment. Although the dustproof mesh can isolate some outdoor dust, the air still carries small dust particles, lint, and other substances. When these particles flow through the fin gaps, they gradually form flocculent dust accumulation. When air flows through this area again, the flow rate will decrease, thereby weakening the heat dissipation effect of the water-cooled structure.

[0022] Please see Figures 1-3 In order to solve the problems existing in the prior art, the purpose of the present invention is to provide a dual-cooling outdoor information communication cabinet. The communication cabinet includes a housing 120 disposed on the top of the base 100, a protective cover 110 disposed on the outside of the housing 120, a back plate 140 installed inside one of the side plates of the housing 120, and a baseband processing unit 141 that generates a large amount of heat is electrically connected to the back plate 140. A water-cooling head 150 for heat conduction is fixedly attached to the side of the baseband processing unit 141 away from the back plate 140. A cooling pipe 200 is sealed and connected to the side of the water-cooling head 150 away from the baseband processing unit 141. Heat dissipation fins 311 are provided below the cooling pipe 200. Multiple sliding bolts 210 are sleeved on the cooling pipe 200. A toggle blade 300 is rotatably connected to the side plate opposite to the side plate connected to the back plate 140. The sliding bolt 210 is used to transfer heat from the radiator tube 200 to the heat dissipation fins 311 to accelerate the heat dissipation speed. When the agitator blade 300 starts to rotate, the agitator blade 300 pushes multiple sliding bolts 210 to move, thereby changing the relative position of the heat dissipation fins 311 and the sliding bolt 210, and at the same time changing the contact position between the sliding bolt 210 and the radiator tube 200. The agitator blade 300 can also scrape away the dust accumulated in the gaps between the heat dissipation fins 311.

[0023] During implementation, the communication cabinet achieves efficient heat transfer and dissipation of the baseband processing unit 141 through a dual cooling mode of "water-cooled conduction + air-cooled convection". At the same time, the continuous rotation of the toggle blade 300 simultaneously completes the thermal stress relief of the cooling radiator 200 and the self-cleaning function of the heat dissipation fins 311. The three work together to ensure heat dissipation efficiency and improve the system's operational stability and durability, adapting to the heat dissipation requirements of the baseband processing unit 141 under long-term high-load operation. It is especially suitable for outdoor communication cabinets and other application scenarios with high dust levels and low maintenance frequency.

[0024] For a better understanding of the above content, please refer to the following: Figure 4 The heat exchange process of the baseband processing unit 141 is disclosed. The water cooling head 150 is made of a high thermal conductivity metal. A liquid storage chamber 151 is sealed on the side of the water cooling head 150 away from the baseband processing unit 141. The liquid storage chamber 151 is used to store coolant.

[0025] Furthermore, a drive blade 153 is rotatably connected to the side of the liquid storage chamber 151 away from the water cooling head 150. The drive blade 153 is driven by a motor. A pair of radiator interfaces 152 are connected to the liquid storage chamber 151. The drive blade 153 is used to drive the coolant to flow between the two radiator interfaces 152.

[0026] It should be disclosed that the materials available for the 150 water block include copper and brass. Copper, with a copper content of ≥99%, is the most common base material for the 150 water block. Its thermal conductivity is as high as 398W / (m·K), second only to silver, enabling it to quickly transfer heat from the heat source to the internal coolant with excellent heat absorption efficiency. It also has good corrosion resistance and plasticity, making it easy to process into a microchannel structure to increase the heat exchange area. Brass is an alloy based on copper and with zinc as the main alloying element. Its copper content is about 80%. Its thermal conductivity is slightly lower than that of copper, but it has higher hardness, better machinability, and a relatively lower price, making it suitable for mass production of the complex 150 water block.

[0027] As a medium for heat transfer, the coolant must meet the requirements of "high specific heat capacity, low viscosity, corrosion resistance, scale prevention, and suitability for operating conditions." Ethylene glycol-based coolants, propylene glycol-based coolants, etc., can be selected based on the actual usage scenario of the communication cabinet.

[0028] Next, as Figure 5 As shown, the radiator pipes 200 are distributed horizontally, and both ends of the radiator pipes 200 are connected to two radiator interfaces 152 respectively, which is used to increase the path of the heated coolant.

[0029] It should be noted that the radiator pipes 200 and heat sink fins 311 of communication cabinets installed outdoors are susceptible to dust intrusion. When horizontally installed, the gaps between the radiator pipes 200 and the heat sink fins 311 are mostly horizontal. Dust particles in the air, after passing through the heat sink fins 311, will fall naturally due to gravity and are unlikely to adhere and accumulate in the gaps. Only a small amount of dust remains on the edges of the heat sink fins 311, which can be quickly removed by blowing with low-pressure airflow during cleaning. However, when the radiator pipes 200 are arranged vertically, the gaps between the heat sink fins 311 are perpendicular to the ground. Dust will be carried into the gaps by airflow and will settle downwards due to gravity, gradually forming a compacted dust blockage at the bottom of the heat sink fins 311. This not only reduces the heat exchange area and increases airflow resistance but also requires a shorter cleaning cycle, increasing maintenance costs. This advantage is particularly significant in outdoor scenarios with a lot of wind, sand, and willow catkins. Furthermore, the air duct design of communication cabinet air-cooling systems often follows the "bottom in, top out" principle. Horizontal radiator pipes 200 can better adapt to the air duct: when arranged horizontally, the radiator pipes 200 extend along the width of the casing 120, the heat dissipation fins 311 are parallel to the airflow direction, and the airflow generated by the exhaust fan 130 can pass evenly through the gaps between the heat dissipation fins 311 along a horizontal path, without significant airflow reversal, resulting in low airflow resistance, lower power consumption of the exhaust fan 130, and uniform airflow distribution across the entire heat dissipation fins 311, avoiding the uneven heat exchange problem of "concentrated airflow in the lower middle and weak airflow in the upper part" in vertical arrangements. Vertically arranged radiator pipes 200 need to be adapted to the vertically oriented air duct, and the airflow is prone to forming vortices at the pipe body bends, which not only weakens heat exchange efficiency but may also lead to local hot spots, especially when multiple radiator pipes 200 are arranged in parallel, the mutual interference of airflow is more obvious.

[0030] exist Figure 6 In the middle, the outer wall of the radiator pipe 200 is fixedly connected to two limiting rings 211 at the two ends of the sliding bolt 210 that are far apart, and the sliding bolt 210 is slidably connected to the outer wall of the radiator pipe 200.

[0031] Based on the above, two limiting rings 211 are distributed along the sliding direction of the sliding bolt 210. A spring 212 is provided between the two ends of the sliding bolt 210 that are far apart and the limiting rings 211. The two ends of the spring 212 are fixedly connected to the spring 212 and the sliding bolt 210 respectively, and the spring 212 is slidably sleeved on the outer wall of the cold air pipe 200.

[0032] In other words, when the coolant inside the radiator pipe 200 is heated, it causes the pipe body to expand and contract due to thermal changes. If the contact position between the sliding bolt 210 and the radiator pipe 200 is fixed, the heat will continue to concentrate in the fixed contact area, causing a temperature difference and deformation difference between this area and other parts of the pipe body, thus forming local thermal stress. The sliding bolt 210 can change the contact position, making the heat distribution of the radiator pipe 200 more uniform, and the thermal stress is dispersed to the entire pipe body, avoiding failures such as pipe bending, weld cracking, or leakage caused by stress concentration.

[0033] Outdoor communication cabinets operate under conditions of large temperature differences between day and night and frequent load fluctuations, causing the cooling radiator pipe 200 to repeatedly undergo thermal expansion and contraction cycles. The movable design of the sliding bolt 210 can dynamically adapt to the thermal deformation displacement of the pipe body, reduce fatigue damage at the fixed contact point, and significantly improve the fatigue life of the cooling radiator pipe 200 and the entire water cooling system.

[0034] Based on the above explanation, the following will further combine... Figures 7-9 Explaining the optimal effect of the combination of the actuating blade 300 and the sliding bolt 210: A mounting plate 310 is fixedly connected to the side of the heat dissipation fin 311 away from the actuating blade 300. The top of the mounting plate 310 is fixedly connected to a plurality of sliding bolts 210 to conduct heat from the plurality of sliding bolts 210 to the heat dissipation fin 311.

[0035] The agitator 300 has a main shaft 301 at its axis for driving its rotation. The main shaft 301 is rotatably connected to the side plate of the housing 120. The main shaft 301 is driven by a motor, and the motor that drives the main shaft 301 to rotate is located on the outside of the housing 120.

[0036] The edge of the agitator blade 300 is covered with a flexible protective layer made of rubber, which is used to scrape away the dust accumulated in the gaps between the heat sink fins 311 while preventing scratches on the side walls of the heat sink fins 311.

[0037] When the spring 212 is in its natural state, the distance between the main shaft 301 and the mounting plate 310 is less than the length of the actuating blade 300.

[0038] It should be noted that when the motor drives the main shaft 301 to rotate, the main shaft 301 drives the agitator 300 on its periphery to rotate. The agitator 300 continuously sweeps the mounting plate 310, causing the sliding bolt 210 to slide along the outer wall of the radiator tube 200. During this process, the spring 212 contracts to store elastic potential energy. When the agitator 300 is no longer in contact with the mounting plate 310, the sliding bolt 210 returns to its original position under the restoring force of the spring 212, thereby changing the relative position of the heat dissipation fins 311 and the radiator tube 200, preventing thermal stress concentration in the radiator tube 200 due to the unchanged contact position with the sliding bolt 210. At the same time, the agitator 300, which continuously inserts into the gaps between the heat dissipation fins 311, scrapes away the accumulated dust in the gaps, preventing it from affecting the heat exchange efficiency between the heat dissipation fins 311 and the airflow delivered by the exhaust fan 130.

[0039] The working principle of the communication cabinet will be explained in detail below: First, during operation, the baseband processing unit 141 on the backplane 140 generates a large amount of heat due to chip computation, signal processing, and other tasks. This heat rapidly accumulates inside the baseband processing unit 141 and diffuses to its surface. Since the water-cooling head 150 is in direct and tight contact with the surface of the baseband processing unit 141, based on the principle of heat conduction, the heat generated by the baseband processing unit 141 is quickly transferred to the interior of the water-cooling head 150, and then conducted from the water-cooling head 150 to the coolant in the cooling pipe 200 connected to it, completing the transfer of heat from the heat source to the cooling medium. Next, the coolant in the radiator tube 200 absorbs heat and its temperature rises. This heat is then transferred through the tube wall to the sliding bolt 210, which acts as a heat-conducting intermediate, further transferring the heat to the connected heat dissipation fins 311. The heat dissipation fins 311 increase their contact area with the air, accelerating heat diffusion to the surrounding air and achieving initial heat dissipation. This reduces the temperature of the radiator tube 200 and the coolant, ensuring the coolant can circulate back to the water block 150 for continuous heat absorption. Meanwhile, the fan located at the top of the housing 120 operates continuously, employing an exhaust design to quickly draw the heated air from inside the housing 120 to the outside, creating a negative pressure environment inside. Under this pressure difference, cool air from the outside environment is automatically replenished into the housing 120, forming a continuous air circulation. When cold air flows over the surface of the heat dissipation fins 311 and the area of ​​the radiator pipes 200, it undergoes forced convection heat exchange with the high-temperature heat dissipation fins 311 and radiator pipes 200, quickly removing heat and further improving heat dissipation efficiency. At the same time, it provides a low-temperature operating environment for components such as the baseband processing unit 141 and the water cooling head 150.

[0040] During the heat dissipation process of the communication cabinet, the cooling radiator 200 will undergo thermal expansion and contraction due to temperature changes. If the contact position between the sliding bolt 210 and the cooling radiator 200 is fixed, it is easy to cause local thermal stress accumulation in the cooling radiator 200. Long-term operation may lead to problems such as deformation of the cooling radiator 200 and loosening of the connection. In this system, the actuating blade 300 rotates continuously, driving the sliding bolt 210 to move axially or radially along the cooling radiator 200 through mechanical linkage. This dynamically changes the contact position between the sliding bolt 210 and the cooling radiator 200, making the heat distribution of the cooling radiator 200 more uniform, avoiding local thermal stress concentration, and improving the structural stability and service life of the cooling radiator 200.

[0041] When cold air enters the housing 120, it carries a small amount of dust particles. As the air flows through the gaps between the heat dissipation fins 311, the dust gradually accumulates due to reduced airflow speed and gravity. If not cleaned regularly, this dust will clog the gaps, reducing the heat exchange area and decreasing heat dissipation efficiency. Because the agitator blades 300 penetrate the gaps between the heat dissipation fins 311 and rotate continuously, their blades scrape away the accumulated dust, removing particles from the surface and gaps of the fins. The removed dust is then either drawn out of the housing 120 by the top fan or settles in a pre-designated dust collection area at the bottom of the housing 120, thus preventing dust accumulation from affecting the heat exchange efficiency of the heat dissipation fins 311.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of the present invention.
