Description

Technical Field

[0001] The utility model relates to the technical field of communication equipment application, in particular to a communication cabinet heat dissipation device and a communication cabinet. Background Art

[0002] As the communications industry continues to evolve, communications cabinets, serving as the control centers of base transceiver stations, face increasing demands for stability and performance in diverse operating environments. These cabinets are not only housed in rooms with constant temperature and humidity, but are also often placed outdoors in diverse environments, such as rooftops, roadsides, and mountainous areas. This makes heat dissipation particularly critical.

[0003] Because communications cabinets contain numerous electronic components, these components generate significant heat during continuous operation. Failure to dissipate this heat promptly and effectively will cause the cabinet's internal temperature to rise, impacting equipment performance and stability, and potentially even causing serious failures or equipment burnout. Therefore, heat dissipation technology for communications cabinets has long been a focus of attention within the communications industry.

[0004] Currently, the mainstream cooling method for communications cabinets in the market mostly uses traditional fan cooling systems. These systems create ventilation holes in the cabinets and install fans, which then use the airflow generated by the fans to dissipate heat from within the cabinets. However, this cooling method has significant limitations. First, a single fan has limited cooling effectiveness. For electronic components located far from the fan, the fan's airflow often fails to effectively reach them, preventing the heat generated by these components from being dissipated promptly. Second, fans have a limited lifespan and are prone to damage from prolonged, high-intensity operation, increasing maintenance costs and the risk of equipment failure.

[0005] To address the shortcomings of traditional fan cooling, a variety of improved communications cabinet cooling solutions have emerged in recent years. Some optimize the layout and number of fans to improve airflow coverage and cooling efficiency. Others utilize more advanced cooling technologies, such as heat pipes and liquid cooling, to enhance cooling effectiveness and equipment stability. However, these solutions often suffer from high costs and complex structures, limiting their application in communications cabinet cooling. Utility Model Content

[0028] In related technologies, the heat dissipation solution for communication cabinets has the following disadvantages:

[0029] Poor heat dissipation: Traditional communications cabinet cooling methods rely primarily on ventilation holes and fans installed within the cabinet. However, this single-fan cooling approach has significant limitations. The airflow generated by the fan often only reaches nearby electronic components, leaving it ineffective for components further away. This results in uneven heat distribution within the cabinet, preventing the heat generated by electronic components farther from the fan from being dissipated over extended periods of time, impacting performance and stability.

[0030] High energy consumption and high costs: Some improved cooling solutions for telecommunications cabinets, such as combining air conditioning and circulating water cooling, improve cooling effectiveness to a certain extent. However, this method consumes a large amount of electricity and increases operating costs. Furthermore, the complex structure and high maintenance costs of such cooling equipment make it unsuitable for long-term use.

[0031] Structural limitations and safety hazards: Some cooling systems may have structural design limitations, such as fixed fan placement and number, which cannot be flexibly adjusted to meet actual needs. Furthermore, the placement of ventilation holes and fans can allow dust and debris to enter the communications cabinet, damaging electronic components and even posing safety risks.

[0032] To address the aforementioned technical issues, the present invention provides a communication cabinet heat dissipation device. This device, through an innovative and efficient heat dissipation structure, achieves efficient heat dissipation of electronic components within the communication cabinet, improving the performance and stability of the electronic components and reducing their failure rate and maintenance costs. This will be described in detail below through specific embodiments.

[0033] like Figures 1 to 3 As shown, the communication cabinet heat dissipation device includes: a water tank 5, a circulation assembly, a circulating water pipe 7, a rotating assembly, and a heat sink. The water tank 5 stores coolant. The water tank 5 is located outside the cabinet 1 of the communication cabinet, and the circulating water pipe 7 is located on the inner wall of the cabinet 1. The water tank 5 is connected to the circulating water pipe 7 via the circulation assembly. The circulation assembly is used to drive the coolant to circulate between the water tank 5 and the circulating water pipe 7. The rotating assembly extends from the water tank 5 into the cabinet 1 and is connected to the heat sink located inside the cabinet 1. The rotating assembly is driven by the circulating flow force of the coolant in the water tank 5 to rotate, thereby driving the heat sink to rotate within the cabinet 1.

[0034] In this embodiment, the water tank, circulating water pipe, circulating component, rotating component and heat sink work together. On the one hand, the coolant circulates between the water tank and the circulating water pipe through the circulating component. On the other hand, the circulating flow force generated drives the rotating component to rotate, and then drives the heat sink to rotate, thereby achieving efficient heat dissipation through the combination and assistance of water cooling and air cooling, with good heat dissipation effect, low cost and simple structure.

[0035] In a specific embodiment, as shown in FIG. Figure 3 As shown, the water tank 5 is located on the top of the cabinet 1.

[0036] In this embodiment, the coolant stored in the water tank 5 can be cooling water. The water tank 5 is fixedly mounted on the top of the cabinet 1 so that the circulation component can utilize the gravity of water when implementing the coolant circulation, thereby reducing energy consumption accordingly.

[0037] In a specific embodiment, Figure 1 and Figure 2 As shown, the circulating water pipes 7 are distributed on the inner walls of the cabinet 1 on two opposite sides.

[0038] In this embodiment, on the opposite sides of the inner wall of the cabinet 1 (such as Figure 1 A circulating water pipe 7 is provided on the left and right sides of the cabinet 1 to introduce the coolant in the water tank 5 into the cabinet 1, so as to better dissipate heat for the electronic components inside the cabinet 1.

[0039] Of course, in addition to the above arrangement, those skilled in the art may also install circulating water pipes 7 on more or fewer inner walls of the cabinet 1 according to actual conditions. Of course, installing more circulating water pipes can achieve better heat dissipation, but will also increase costs accordingly; installing fewer circulating water pipes can reduce costs, but will also weaken the heat dissipation effect accordingly.

[0040] In a specific embodiment, Figure 2 As shown, the circulating water pipe 7 adopts an S-shaped circulating structure.

[0041] In this embodiment, the circulating water pipe 7 adopts an S-shaped circulation structure and is distributed on the inner walls of the cabinet 1 on two opposite sides, which can ensure that the coolant flows through the circulating water pipe at a uniform speed and absorbs heat.

[0042] In a specific embodiment, Figure 2 As shown, the circulation assembly includes: an inlet pipe 8, a first water pump 9, a drain pipe 10, and a second water pump 11. The inlet pipe 8 and the drain pipe 10 are respectively connected to the water inlet end and the drain end of the circulating water pipe 7. The first water pump 9 is connected to the inlet pipe 8 and is used to drive the coolant from the water tank 5 through the inlet pipe 8 into the circulating water pipe 7. The second water pump 11 is connected to the drain pipe 10 and is used to drive the coolant from the circulating water pipe 7 through the drain pipe 10 back to the water tank 5.

[0043] Specifically, one end of the water inlet pipe 8 is connected to the water inlet end of the circulating water pipe 7, and the other end of the water inlet pipe 8 extends upward to near the top of the water tank 5. One end of the drain pipe 10 is connected to the drain end of the circulating water pipe 7. A first water pump 9 is installed outside the water inlet pipe 8, and a second water pump 11 is installed outside the drain pipe 10. Through the provided circulation components, the water in the circulating water pipe 7 can be circulated.

[0044] In this embodiment, the circulation component is located inside the water tank 5, wherein the water inlet pipe 8 introduces the coolant in the water tank 5 into the circulating water pipe 7, the first water pump 9 is used to drive the coolant to flow in the circulating water pipe 7, the drain pipe 9 returns the coolant in the circulating water pipe 7 to the water tank 5, and the second water pump 11 is used to drive this reflux process. By cooperating with the first water pump 9 and the second water pump 11, the flow speed and flow direction of the coolant in the circulating water pipe 7 are controllable, thereby realizing the circulation of the coolant and ensuring the continuity of the cooling effect inside the cabinet.

[0045] In a specific embodiment, Figure 3As shown, the rotating assembly includes a rotating shaft 15 and an impeller 16. The impeller 16 includes multiple blades, which can be three or more and evenly distributed. The rotating shaft 15 passes through the connection between the water tank 5 and the cabinet 1, with one end located inside the water tank 5 and the other end located inside the cabinet 1. The end located inside the water tank is connected to the impeller 16, and the other end located inside the cabinet is connected to the heat sink. The rotating assembly is configured to drive the rotating shaft 15 to begin rotating.

[0046] In this embodiment, when the water tank 5 is disposed on the top of the cabinet 1, the rotating shaft 15 is vertically disposed at the junction between the bottom of the water tank 5 and the top of the cabinet 1. One end of the rotating shaft 15 extends upward into the interior of the water tank 5 and the other end extends downward into the interior of the cabinet 1. The rotating shaft 15 is rotatably connected to the junction. The impeller 16 is fixedly connected to the top of the rotating shaft 15, and the heat sink is fixedly connected to the bottom of the rotating shaft 15. The heat sink is disposed below the inner wall of the top of the cabinet 1.

[0047] In a specific embodiment, Figure 3 As shown, the heat dissipation element includes a plurality of fan blades 17 , and the ends of the plurality of fan blades 17 are connected to the other end of the rotating shaft 15 located inside the cabinet 1 .

[0048] The number of blades 17 can range from three to eight, and the specific number can be set and adjusted by those skilled in the art based on actual needs. Furthermore, the blades 17 should be evenly distributed to enhance the uniformity of air flow. By designing the number and distribution of blades 17, the uniformity and effectiveness of the heat dissipation effect can be ensured.

[0049] The heat sink adopts a plurality of fan blades 17. When the rotating shaft 15 rotates, the plurality of fan blades 17 also rotates, blowing air to dissipate heat inside the cabinet 1. The rotation of the fan blades 17 can achieve comprehensive heat dissipation of the components inside the cabinet, avoiding the problem of local overheating in the cabinet 1.

[0050] In this embodiment, with the rotating shaft 15 positioned vertically, a plurality of fan blades 17 are fixedly connected to the bottom of the rotating shaft 15 and are configured to rotate driven by the circulating flow force of the coolant in the water tank 5 to blow heat out of the interior of the cabinet 1. Since the circulating flow force is used to drive the fan blades 17, there is no need for a separate motor to drive the fan blades 17, which saves energy, reduces costs, and makes the device more compact.

[0051] In a specific embodiment, Figure 3 As shown, the rotating assembly further includes a rotating shaft seal 14 . The rotating shaft seal 14 is sleeved on the rotating shaft 15 and is located at the connection between the water tank 5 and the cabinet 1 .

[0052] In this embodiment, by providing a shaft seal 14 at the connection between the rotating shaft 15 , the water tank 5 and the cabinet 1 , the coolant in the water tank 5 can be effectively prevented from flowing into the cabinet 1 .

[0053] In a specific embodiment, Figure 3 As shown, the circulation assembly further includes: a connecting pipe 12 and a high-pressure nozzle 13. One end of the connecting pipe 12 is connected to the drain pipe 10, and the other end of the connecting pipe 12 is connected to the high-pressure nozzle 13, which is facing the impeller 16.

[0054] Specifically, one end of the drain pipe 10 is connected to the drain end of the circulating water pipe 7, the other end of the drain pipe 10 is connected to one end of the connecting pipe 12, the other end of the connecting pipe 12 is connected to the high-pressure nozzle 13, and the impeller 16 should be compatible with the high-pressure nozzle 13.

[0055] The high-pressure nozzle 13 is used to spray coolant from the circulating water pipe 7 toward the impeller 16. The jet has a high flow rate and high pressure, which drives the impeller 16 to rotate. The rotation of the impeller 16 drives the rotation shaft 15, which in turn drives the blades 17. The adaptive design of the impeller 16 and the high-pressure nozzle 13 ensures that the impact force of the water flow can be effectively converted into the rotational force of the rotating shaft 15, thereby driving the rotation of the blades 17.

[0056] In this embodiment, the rotating shaft 15 and impeller 16 in the rotating assembly, the connecting pipe 12 and high-pressure nozzle 13 in the circulation assembly, and the fan blades 17 are used in conjunction with the fan blades 17 to convert the power of water into mechanical power, thereby driving the fan blades 17 to rotate and dissipate heat.

[0057] In a specific embodiment, Figures 1 to 3 As shown, a plurality of ventilation holes 6 are provided on the inner wall of the cabinet 1. The plurality of ventilation holes 6 are arranged in an array. The heat inside the cabinet 1 can be discharged from the ventilation holes 6 by rotating the heat sink.

[0058] In this embodiment, a plurality of ventilation holes 6 are provided on the inner wall of the cabinet 1 to ensure that heat inside the cabinet 1 can be effectively discharged and to prevent the temperature inside the cabinet 1 from being too high. The ventilation holes 6 can be arranged in a rectangular array or a circular array. By designing the number and arrangement of the ventilation holes 6, the uniformity and effectiveness of the heat dissipation effect can be ensured.

[0059] Furthermore, the ventilation holes 6 are preferably distributed on the inner wall of one side of the cabinet 1, and are different from the inner wall where the circulating water pipe 7 is set. For example, the ventilation holes 6 are distributed on the inner wall where the back of the cabinet 1 is located, and the circulating water pipe 7 is set on the inner walls on the left and right sides of the cabinet 1.

[0060] like Figures 1 to 3 As shown, the working principle of the communication cabinet heat dissipation device is as follows:

[0061] When it is necessary to dissipate heat from the communication cabinet that generates heat during operation, the first water pump 9 is started first. At this time, the first water pump 9 extracts the coolant inside the water tank 5 to the circulating water pipe 7 through the water inlet pipe 8. At this time, the coolant inside the circulating water pipe 7 can absorb the heat inside the cabinet 1. Subsequently, the second water pump 11 is started. At this time, the coolant inside the circulating water pipe 7 will pass through the drain pipe 10 and the connecting pipe 12 and then be ejected from the high-pressure nozzle 13. At this time, the coolant ejected from the high-pressure nozzle 13 will impact the impeller 16, driving the impeller 16 to start rotating, and the rotation of the impeller 16 can drive The rotating shaft 15 rotates, and the rotation of the rotating shaft 15 can drive the fan blades 17 to start rotating. At this time, the fan blades 17 can blow air to the inside of the cabinet 1 and discharge the heat from the ventilation holes 6. The rotating shaft seal 14 provided can prevent the coolant inside the water tank 5 from flowing into the interior of the cabinet 1. By setting up the above structure, it is convenient for the staff to dissipate heat from the electronic components inside the cabinet 1. The heat dissipation effect is better, and the electronic components inside the cabinet 1 are fully cooled, avoiding the disadvantage that traditional fans cannot dissipate heat to electronic components that are far away, which greatly facilitates the use of the staff.

[0062] The present invention also provides a communication cabinet. Figures 1 to 3 As shown, the communication cabinet includes: a cabinet body 1 and the above-mentioned communication cabinet heat dissipation device arranged in the cabinet body 1.

[0063] In actual application, when the electronic components inside the communication cabinet start working, a large amount of heat will be generated. At this time, the first water pump 9 can be started to allow the coolant in the water tank 5 to enter the circulating water pipe 7 through the water inlet pipe 8. The coolant in the circulating water pipe 7 will absorb the heat inside the cabinet 1 and reduce the temperature inside the cabinet 1. At the same time, the second water pump 11 is started to allow the coolant in the circulating water pipe 7 to be ejected through the drain pipe 10, the connecting pipe 12 and the high-pressure nozzle 13. The coolant ejected from the high-pressure nozzle 13 will impact the impeller 16, driving the impeller 16 to start rotating. The rotation of the impeller 16 will drive the rotating shaft 15 and the fan blades 17 to rotate. The rotation of the fan blades 17 will blow air into the cabinet 1 and discharge the heat from the ventilation holes 6. Through such a circulation process, comprehensive heat dissipation of the electronic components inside the communication cabinet can be achieved, ensuring the stable operation of the communication cabinet.

[0064] In a specific embodiment, Figure 1 and Figure 2 As shown, the communication cabinet further includes a cabinet door 3. The cabinet body 1 adopts a hollow structure with one side open, and the cabinet door 3 is arranged at the opening of the cabinet body 1 and is detachably connected to the cabinet body 1.

[0065] In this embodiment, the shape of the cabinet 1 can be a rectangular parallelepiped, or can be set to other shapes according to site conditions, such as a cube, a prism, a cylinder, a truncated cone, or even a polyhedron.

[0066] The cabinet body 1 is generally opened on the side, and the cabinet door 3 is arranged at the opening on the side of the cabinet body 1 to facilitate the maintenance and repair of the electronic components inside the cabinet body by the staff.

[0067] The cabinet body 1 and the cabinet door 3 can be connected in a hinged manner, that is, the cabinet door 3 is hinged on one side of the cabinet body 1 to facilitate opening and closing of the cabinet door 3.

[0068] Furthermore, if Figure 1 As shown, the communication cabinet further includes a handle 4 . The handle 4 is provided on the cabinet door 3 .

[0069] In this embodiment, the handle 4 is fixedly connected to one side of the outer surface of the cabinet door 3. The handle 4 can be made of rubber material, which is convenient for the user to operate and provides a comfortable grip, thereby ensuring the comfort and safety of the user.

[0070] In a specific embodiment, Figure 1 As shown, the communication cabinet further includes: a plurality of support bases 2. The plurality of support bases 2 are arranged at the bottom of the cabinet body 1.

[0071] When the cabinet body 1 is in the shape of a rectangular parallelepiped, a support base 2 is fixedly connected to each of the four corners of the bottom of the cabinet body 1, for a total of four support bases 2, for supporting and stabilizing the entire cabinet body 1. Furthermore, if the bottom surface of the cabinet body 1 is large, in order to ensure the stability of the cabinet body 1, one or more additional support bases 2 can be provided in the middle area of the bottom of the cabinet body 1.

[0072] In addition, when the cabinet 1 is of other shapes, the support bases 2 are evenly distributed at the edge of the bottom of the cabinet 1 , and one or more support bases 2 may be additionally provided in the middle area of the bottom of the cabinet 1 as needed.

[0073] The communication cabinet heat dissipation device and communication cabinet provided in the embodiments of the present invention address the problems of poor heat dissipation effect, high energy consumption and high cost, structural limitations and safety hazards existing in the communication cabinet heat dissipation solutions in the related art, and provide an efficient, energy-saving and safe heat dissipation solution to meet the communication industry's demand for communication cabinet heat dissipation technology.

[0074] Specifically, the entire system architecture design of the present invention, including the layout, connection method, and functional coordination of various components and assemblies such as the water tank, circulating water pipes, circulating components, rotating components, and heat sinks, achieves efficient and comprehensive heat dissipation for the electronic components within the communication cabinet. The coolant in the circulating water pipes effectively absorbs heat from the cabinet, while the design of the rotating components and fan blades enhances the heat dissipation effect and ensures uniform heat distribution within the communication cabinet. Compared with traditional fan cooling methods, the present invention has better heat dissipation and can prevent damage to the electronic components within the communication cabinet due to overheating.

[0075] The heat dissipation solution provided by the utility model has the following advantages:

[0076] Improved heat dissipation: By installing circulating water pipes on opposite sides of the cabinet's inner wall, the coolant in the water tank absorbs heat from the cabinet, achieving comprehensive heat dissipation for the electronic components within the communication cabinet. Furthermore, the built-in rotating assembly and multiple fan blades enhance heat dissipation, ensuring even heat distribution within the cabinet and extending the service life of the electronic components within the cabinet.

[0077] Reduced energy consumption and costs: The circulating water cooling system uses less energy and costs than other cooling methods such as air conditioning. Furthermore, the heat dissipation device has a relatively simple structure and low maintenance costs, which is conducive to long-term use.

[0078] Optimized structural design: The heat sink's structure is rationally designed and can be flexibly adjusted based on actual needs. Furthermore, seals and waterproofing measures (i.e., shaft seals) prevent coolant from the water tank from flowing into the cabinet, ensuring the safe operation of the electronic components within the communications cabinet.

[0079] 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 above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
