TECHNICAL FIELD
[0001] The present application relates to the technical field of base station temperature control, and particularly relates to a communication cabinet capable of realizing efficient thermal management. BACKGROUND
[0002] With the rapid development of science and technology and the popularity of the Internet, 5G, big data, artificial intelligence and smart industry have penetrated into various aspects of social industry and significantly influenced people's lifestyle. Infrastructure construction such as communication cabinet has become a key pillar supporting the development and promotion of information application. It is predicted that electronic equipment will consume 20.9% of the global power in 2030, most of which will be released in the form of heat energy, and the greenhouse gas generated is expected to account for 23% of the total global emissions. Correspondingly, the construction status of communication base stations and communication cabinets closely related thereto in China is still in the stage of rapid development, and there is still a great demand, so it also puts forward more severe challenges to the service life, energy saving and efficiency of the communication base station.
[0003] However, the heat dissipation problem of the cabinet has many adverse effects on the energy consumption, service life and other aspects of the communication base station. Generally speaking, in terms of structure, the traditional base station cabinet adopts the method of installing an air conditioner or a heat exchanger at the door panel or installing an air conditioner at one end of the cabinet for heat dissipation treatment. The disadvantage of the former is that, due to the small space of the integrated cabinet, when the equipment is densely stacked, the side in contact with the cold source is equivalent to a nearly air-tight wall, and the cold air is easy to flow back directly without passing through the equipment, resulting in insufficient heat exchange of the equipment, and a large amount of heat accumulation leading to high temperature alarm. The disadvantage of the latter is that, due to the lack of standardized installation process, when there is too much shielding between the high-temperature heat source and the cold source, the cold air is folded multiple times and its flow rate decays to zero before reaching the heat source, and the heat source can only exchange heat with the environment through radiation and extremely weak natural convection, resulting in poor heat exchange effect and high temperature alarm. At the same time, due to the influence of installing the air conditioner outdoor unit, the structure of the traditional cabinet is not regular, which brings problems to the installation allowance, floor area, equipment maintenance, etc. In addition, various new heat dissipation methods are being gradually proposed and applied, but the existing traditional communication cabinet structure design idea is old, and the newly developed technologies are not effectively applied to the actual scene, which becomes a problem that needs to be solved urgently. In terms of operation, the existing cabinet will encounter serious instantaneous temperature rise when dealing with short-term high load and high temperature environment, and the fan and air conditioning subsystems are prone to processing capacity lag and overloading, significantly increasing the instability of the equipment operation and energy consumption in the communication cabinet. For example, during the daytime communication data interaction peak and summer sunny day temperature peak, the downtime and maintenance rate increase sharply. On this basis, since the working process of the communication cabinet has time periodicity, the load peak does not occur in all running time within a cycle, and there is a relatively idle time period for the cold source, so whether the heat generated by the load peak can be effectively "spatial and temporal transfer" becomes a possibility for introducing new heat management methods. At the same time, the old cabinet internal structure and arrangement method has been unable to meet the increasing demand of server load in base stations, and the problems of low space utilization, high maintenance cost, high energy consumption and serious downtime are becoming more and more prominent, which seriously hinders the stable operation of the outdoor communication base station.
[0004] Therefore, to enable the base station to work normally for a long time, the heat management problem needs to be solved. In order to comply with the rapid development trend of domestic communication base stations and achieve the goal of green carbon reduction of communication infrastructure, the heat management problem of the cabinet has become a major problem that needs to be solved in the industry at present, and the solution of the heat management problem depends largely on good air duct design, space layout design and the introduction of new heat management methods in the cabinet. Therefore, it is necessary to innovatively design the cabinet structure and heat management function. SUMMARY
[0005] The purpose of this invention is to propose a communication cabinet that achieves efficient thermal management, in order to solve the problems of low cold source utilization, difficulty in passing peak load periods, and unreasonable flow channel design in existing communication cabinets.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A communication cabinet for efficient thermal management includes a cabinet body, a security structure, a phase change cladding, a cooling system, and mounting brackets. The cabinet body comprises a main compartment, a rectangular roof, and a bottom air intake box. One side of the long side of the main compartment has two hinged doors, and the other side has two hinged doors. One side of the short side of the main compartment has a hinged grille door the size of an air conditioner outdoor unit. The cabinet contains mounting brackets for installing communication servers, power supplies, and other equipment. These mounting brackets are installed on the bottom surface of the main compartment, extending through the entire main compartment and distributed throughout the compartments of the communication cabinet for efficient thermal management. The security structure consists of an antenna bracket and a monitoring bracket on the short outer side, as well as a transmission and connection structure and a generator socket extending into the cabinet. The phase change cladding is a variable-position heat storage module applied inside the cabinet and attached to equipment or air ducts. The cooling system includes a cabinet air conditioner with an insulated door on the surface of the short side of the cabinet, an air conditioner outdoor unit in the middle of one of the compartments, a ventilation fan placed between the ceiling and the main installation compartment, the ventilation fan being placed on top of the main installation compartment and connected to the ceiling space, and a radiative cooling coating applied to the outer surface of the cabinet, basically covering all outer surfaces of the cabinet except the bottom.
[0007] Preferably, the cabinet air conditioner is a wall-mounted split-type air conditioner, and the cabinet air conditioner is installed on the short side door of the main compartment.
[0008] Preferably, the outdoor unit of the air conditioner is placed in the middle of one of the compartments of the cabinet and blows hot air out toward the short side grille hinged door.
[0009] Preferably, the mounting frame may have unevenly distributed mounting holes, and there are unequal gaps between adjacent mounting positions of the mounting frame in different directions.
[0010] Preferably, the mounting frame is equipped with modular devices, including but not limited to communication equipment modules, power modules, wiring equipment modules, power supply modules, BBUs, and transmission equipment modules.
[0011] Preferably, a crane ring for easy installation can be added to the top of the cuboid canopy.
[0012] Preferably, air vent grilles are provided on all sides of the rectangular roof.
[0013] Preferably, the bottom air inlet box is provided with an air inlet mesh, a cable / optical cable inlet, a forklift hole, and an air outlet.
[0014] Preferably, the outer surface of the communication cabinet is coated with a radiation-cooling coating.
[0015] Preferably, the communication cabinet is equipped with a security structure, wherein the antenna bracket and the monitoring bracket are placed on the outside of the cabinet and connected inward to the internal transmission and communication components and the generator socket.
[0016] Preferably, the communication cabinet contains a phase change material cladding layer for creating a "temperature buffer platform," the location of which is related to the internal equipment layout scheme and is mainly attached to the equipment and air ducts.
[0017] Preferably, the cooling system comprises a modular switching and monitoring system, an adjustable air conditioner, an environmental monitor, a temperature monitor, electrical equipment, logic devices, and a fan.
[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. By adopting a compartmentalized layout and optimized configuration, and following a one-compartment-one-row server configuration, the arrangement of servers within the communication cabinet has been changed. Innovatively, a split-type cabinet air conditioner is fully integrated within the cabinet, and the distribution of heat-generating servers and the internal structural layout of the cabinet have been optimized. Compared to existing communication cabinet designs on the market, the internal airflow heat exchange efficiency is significantly improved, the cold air residence time is extended, and the airflow field within the cabinet is greatly improved. This alleviates the difficulty of insufficient heat exchange between cold air and server equipment in the previous single-row cabinet structure, improving the distribution of the internal airflow and temperature field. Simultaneously, the number of cabinet compartments can be freely assembled or increased, effectively reducing the temperature of heat-generating components and the internal environment of the cabinet. This ensures that power supplies, BBUs, transmission equipment, and other modules can receive effective and sustained cooling simultaneously, thereby guaranteeing the normal operation of the base station and extending the service life of the modules and the base station.
[0019] 2. This innovative approach to communication cabinet thermal management utilizes a combination of phase change cladding, radiative coating, cuboid roof, main installation compartment, and bottom air intake box. It employs multiple methods, including phase change heat storage, radiative cooling, natural convection, and forced convection. When the ambient temperature is low, fans drive bottom air intake and top exhaust, utilizing external cold sources for heat dissipation. When the ambient temperature is high, active cooling via air conditioning utilizes internal cold sources. When dealing with rapid increases in ambient temperature or peak load periods due to surges in communication data traffic, the phase change cladding acts as a "temperature buffer platform," mitigating the impact of short-term, transient temperature increases that the air conditioning and fan subsystems cannot handle. The phase change material's heat storage capacity transfers a large amount of heat generated during peak periods to lower load periods, reducing the heat dissipation requirements of the fan and air conditioning subsystems. Simultaneously, the radiative cooling coating applied to the cabinet's outer surface significantly reduces the impact of sunlight or surrounding heat sources on the communication cabinet's radiative heat transfer, minimizing excessive heating caused by external radiation on the cabinet's outer surface. Compared to traditional communication cabinets, this invention features two heat dissipation schemes and two improved temperature control designs, adding an emergency heat storage source and a new heat dissipation path. It also innovatively designs a new cabinet structure, with bottom air intake and top air exhaust, ensuring that the heated airflow after heat exchange with the server follows the natural upward flow phenomenon. Furthermore, it innovatively introduces a radiative cooling and heat insulation path and a "temperature buffer platform" phase change cladding instantaneous load peak processing function. This ensures the cabinet accurately cools and de-temperatures heat-generating components, effectively reducing the heat dissipation requirements of the fan and air conditioning subsystems, lowering energy consumption, and maintaining the temperature of related communication modules within a reasonable range over the long term. This reduces downtime and alarm rates during operation, enhancing energy efficiency.
[0020] 3. A novel modular switching cooling and temperature control technology is proposed. This technology can actively adjust the operating modes of fans and air conditioners based on environmental conditions and temperature sensor data, and comprehensively regulate the system by considering factors such as the heat storage of the phase change cladding. When the fans relying on external cooling sources cannot meet the heat dissipation or dehumidification requirements, the system switches to the internal cooling source, the air conditioner, through a modular control mechanism. Compared to traditional cabinets, this technology can intelligently allocate power resources under different environmental and load conditions, significantly expanding the normal operating temperature range and equipment load capacity of communication cabinets, while achieving energy savings and carbon emission reduction. Furthermore, it can effectively reduce the frequency of on-site maintenance, parts replacement rate, number of repairs, and operational accidents, thereby comprehensively reducing operation and maintenance costs.
[0021] 4. The distance and location relationship between heat-generating equipment and air conditioners have been changed, optimizing the layout of split-type air conditioners. The air conditioner is placed independently in a separate compartment, and the outdoor unit is effectively isolated from other internal spaces within the cabinet. This allows the cool air to be effectively blown into each server compartment, enhancing the heat exchange area. Simultaneously, the overall structure of the cabinet using split-type air conditioners is neat and uniform, without large protruding structures or independent, separate components. Compared to traditional cabinets, this effectively prevents the formation of walls that block cold air after servers are stacked, allowing equipment cooling to rely primarily on convection heat exchange with large temperature differences and high flow rates. It also improves upon the various assembly, security, and layout issues encountered when installing outdoor units in traditional communication cabinets using split-type air conditioners, simplifying the installation and protection constraints for actual application.
[0022] 6. A reasonable overall architecture has been designed and optimized. Compared with traditional server racks on the market, more effective protection measures and convenient design have been adopted. Components such as roof, heat-insulating cabinet door, and air intake mesh have been added to achieve functions such as waterproof, dustproof, moisture-proof and rodent-proof, effectively improving the service life of the server rack and ensuring the safe operation of the server.
[0023] 7. A security structure has been added to monitor changes in the outdoor environment of the communication cabinet in real time, protecting the communication cabinet from damage or shutdown caused by abnormal external influences, increasing the security level of the communication cabinet, reducing maintenance costs, achieving real-time protection, and adding possible additional functions.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0027] In one embodiment of the present invention: Refer to Figures 1-5 A communication cabinet for efficient thermal management includes a cabinet body 1, a security structure 2, a phase change cladding 3, a cooling system 4, and a mounting frame 5. The cabinet body 1 consists of a main compartment 101, a cuboid roof 102, and a bottom air intake area. Two hinged doors 103 are located on one side of the long side of the main compartment 101, and two hinged doors 103 are located on the other side. A hinged grille door 104, the size of an air conditioner outdoor unit, is located on one side of the short side of the main compartment 101. The mounting frame 5, which houses communication servers, power supplies, and other equipment, is installed inside the cabinet and extends through the entire main compartment 101. The security structure 2 includes an antenna bracket 201 and a monitoring bracket 202 located on the outer side of the short side, as well as a transmission and connection structure 203 and a generator socket 204 extending into the cabinet. The monitoring bracket provides a platform for mounting cameras. The internal structure of the cabinet allows for adjustments to the security structure. The phase change cladding 3 is a... The encapsulated component containing phase change material is positioned and adjusted appropriately according to the installation of the cabinet equipment, generally closely attached to the equipment and air duct. The cooling system 4 includes a cabinet air conditioner 401 with an insulated door on one side of the cabinet, an outdoor air conditioner 402 located in the middle of one compartment, a ventilation fan 403 located between the ceiling and the main installation compartment 101, and a radiative cooling coating 404 coated on the outer surface of the cabinet. The ventilation fan 403 is located on the top of the main installation compartment 101 and connects it to the ceiling space. The radiative cooling coating basically covers all the outer surfaces of the cabinet except the bottom. Air outlet grilles 6 are provided on all sides of the cuboid ceiling. The cabinet air conditioner 401 is a suspended split-type air conditioner, installed on the short side door of the main compartment 101. The outdoor air conditioner 402 is installed in the reserved area in the middle of one compartment, and the air outlet of the outdoor unit faces the grille door 104 on the short side. At the same time, the outdoor unit is isolated from other spaces inside the compartment by a heat insulation layer. The swing doors 103 are all heat-insulated cabinet doors.
[0028] By adopting a compartmentalized layout and optimized configuration, with servers arranged in one row per compartment, the arrangement of servers within the communication cabinet has been changed. Innovatively, a split-type cabinet air conditioner is fully integrated within the cabinet, and the distribution of heat-generating servers and the internal structural layout of the cabinet have been optimized. Compared to existing communication cabinet designs on the market, the internal airflow heat exchange efficiency is significantly improved, the cold air residence time is extended, and the airflow field within the cabinet is greatly improved. This alleviates the difficulty of insufficient heat exchange between cold air and server equipment in the previous single-row cabinet structure, shortens the cold air circulation path, improves the distribution of the internal airflow and temperature field, and allows for flexible assembly of cabinet compartments. This effectively reduces the temperature of heat-generating components and the internal environment of the cabinet, ensuring that power supplies, BBUs, transmission equipment, and other modules can receive effective and sustained cooling simultaneously, thereby guaranteeing the normal operation of the base station and extending the service life of the modules and the base station.
[0029] By combining phase change cladding, radiative coating, cuboid roof, main installation compartment, and bottom air intake box, this innovative approach utilizes multiple methods for heat dissipation in communication cabinets, including phase change heat storage, radiative cooling, natural convection, and forced convection. When the ambient temperature is low, fans drive bottom air intake and top exhaust, utilizing external cold sources for heat dissipation. When the ambient temperature is high, active cooling via air conditioning utilizes internal cold sources. When dealing with rapid increases in ambient temperature or peak load periods due to surges in communication data traffic, the phase change cladding acts as a "temperature buffer platform," mitigating the impact of short-term, transient temperature increases that the air conditioning and fan subsystems cannot handle. Through the heat storage capacity of the phase change material, a large amount of heat generated during peak periods is transferred to lower load periods for release, reducing the heat dissipation requirements of the fan and air conditioning subsystems. Simultaneously, the radiative cooling coating applied to the cabinet's outer surface significantly reduces the impact of sunlight or surrounding heat sources on the communication cabinet's radiative heat transfer, minimizing excessive heating of the cabinet's outer surface caused by external radiation. Compared to traditional communication cabinets, this invention features two heat dissipation solutions and two improved temperature control designs, adding an emergency heat storage source and a new heat dissipation path. It also innovatively designs a new cabinet structure with bottom air intake and top air exhaust, ensuring that the heated airflow after heat exchange with the server follows the natural upward flow phenomenon. Furthermore, it innovatively introduces a radiative cooling and heat insulation path and a "temperature buffer platform" phase change cladding instantaneous load peak handling function. This ensures the cabinet accurately cools and de-temperatures heat-generating components, effectively reducing the heat dissipation capacity requirements of the fan and air conditioning subsystems, lowering energy consumption, and maintaining the temperature of related communication modules within a reasonable range over the long term. This reduces downtime and alarm rates during operation, enhancing energy efficiency. Depending on the installation requirements, the internal component arrangement and mounting frame layout remain unchanged when installing cabinets of different sizes.
[0030] In this embodiment, as Figures 1-3 As shown, the communication cabinet is equipped with a security structure 2, in which the antenna bracket and the monitoring bracket are placed on the outside of the cabinet and connected inward to the internal transmission and communication components and the generator socket.
[0031] Security features have been added to monitor changes in the outdoor environment of the communication cabinet in real time, protecting the cabinet from damage or shutdown caused by abnormal external influences, increasing the security level of the cabinet, reducing maintenance costs, achieving real-time protection, and adding possible additional functions.
[0032] In this embodiment, a phase change material cladding 3 for creating a "temperature buffer platform" is placed inside the communication cabinet. Its position is related to the internal equipment layout scheme and is mainly attached to the equipment and air duct.
[0033] When dealing with periods of peak equipment load caused by a rapid increase in ambient temperature or a surge in communication data traffic, the phase change cladding will function as a "temperature buffer platform" to fill the short-term transient rapid temperature rise that the air conditioning and fan subsystems cannot handle. Through the heat storage capacity of the phase change material, a large amount of heat generated during peak periods will be transferred to low-load periods for release, reducing the heat dissipation demand of the fan and air conditioning subsystems.
[0034] In this embodiment, as Figures 1-2 As shown, the rack air conditioner 401 is a wall-mounted split-type air conditioner, installed on the short side door of the main compartment 101. The outdoor unit of the air conditioner is placed in the middle of one of the compartments of the rack and blows hot air towards the short side grille swing door.
[0035] The design alters the distance and location relationship between heat-generating equipment and air conditioning units, and optimizes the layout of split-type air conditioners. The rack-mounted air conditioner 401 and the outdoor unit 402 are placed independently within a single compartment. The outdoor unit is effectively isolated from other internal spaces and integrated into the rack, allowing cool air to effectively reach each server compartment and enhancing heat exchange. This also results in a more uniform and streamlined rack structure, free of large protruding structures or separate components. Compared to traditional racks, this design effectively prevents the formation of walls that block cool air after servers are stacked, ensuring that cooling relies primarily on high-temperature, high-velocity convection heat transfer. Furthermore, it addresses various assembly, security, and layout issues encountered when installing outdoor units in traditional communication racks, simplifying installation and protection constraints for practical applications.
[0036] In this embodiment, as Figure 1 As shown, the outer surface of the communication cabinet is coated with radiation cooling coating 404.
[0037] The radiation cooling coating applied to the outer surface of the cabinet will significantly reduce the impact of sunlight or surrounding heat sources on the radiative heat transfer of the communication cabinet, and reduce the excessive temperature rise caused by external radiation on the outer surface of the cabinet.
[0038] In this embodiment, as Figures 1-2 As shown, there are unequal gaps between adjacent installation positions of the mounting frame 5 in different directions. The mounting frame 5 is equipped with modular devices, including but not limited to communication equipment modules, wiring equipment modules, BBU, power modules, power supply modules, and transmission equipment modules.
[0039] In this embodiment, a crane ring can be added to the top of the cuboid ceiling for easy installation. The crane ring facilitates the hoisting and movement of the installed cabinet body.
[0040] In this embodiment, as Figure 1 As shown, the bottom air inlet box has an air inlet mesh 7, a cable / optical cable inlet, a forklift hole, and an air outlet.
[0041] The overall architecture has been designed and optimized. Compared with traditional server racks on the market, more effective protection measures and convenient design have been adopted. Components such as the canopy 102, heat-insulating cabinet door 103, and air intake mesh 7 have been added to effectively achieve functions such as waterproofing, dustproofing, moisture-proofing, and rodent-proofing, effectively improving the service life of the server rack and ensuring the safe operation of the server.
[0042] In this embodiment, as Figures 1-2 As shown, the cooling system consists of a modular switching and monitoring system, an adjustable air conditioner, an environmental monitor, a radiant cooling coating, a temperature monitor, and a fan.
[0043] A novel modular switching cooling and temperature control technology is proposed.
