Description

Technical Field

[0001] The present invention relates to the technical field of heat dissipation of electrical cabinets, and in particular to a high-efficiency heat dissipation structure of an electrical cabinet and a method of using the same. Background Art

[0002] In modern industrial control systems, electrical cabinets, as crucial carriers of electrical control equipment, are widely used in fields such as power distribution, automation, communications, rail transit, and energy. With the increasing integration of equipment, electrical cabinets now house a large number of electrical components, such as PLC modules, inverters, contactors, power modules, and various sensor interfaces. These components generate significant heat during long-term operation. Failure to dissipate this heat promptly and effectively will cause the temperature inside the cabinet to rise continuously, leading to problems such as performance degradation of electronic components, aging of insulation materials, system malfunctions, and component overheating and damage. In severe cases, this can even cause fires, endangering equipment safety and human life. Therefore, achieving efficient, stable, and reliable heat dissipation in electrical cabinets is a key technical challenge currently facing the electrical engineering and automation fields.

[0003] Currently, traditional electrical cabinet cooling methods primarily include natural convection, fan-forced ventilation, heat exchangers, and air conditioning. However, all of these methods have limitations in practical application. Natural convection cooling relies on air temperature differences, resulting in low cooling efficiency and difficulty meeting the cooling needs of densely installed equipment. Fan ventilation, while inexpensive, is susceptible to dust and oil accumulation, affecting air duct flow and increasing maintenance costs. Heat exchangers and air conditioning systems, while effective, are associated with high equipment costs and energy consumption, hindering the achievement of energy conservation and environmental protection goals. Furthermore, as equipment installation spaces become increasingly compact and control system reliability requirements increase, traditional cooling methods are struggling to adapt to increasingly complex operating environments. Therefore, there is an urgent need to develop a high-efficiency electrical cabinet cooling structure and its associated cooling solutions that are rationally designed, highly efficient, and easy to maintain, to ensure the long-term, stable operation of electrical equipment.

[0004] In view of the above situation, in order to overcome the above technical problems, the present invention designs a case name to solve the above technical problems. Summary of the Invention

[0005] The technical purpose to be achieved by the present invention is to propose an efficient electrical cabinet heat dissipation structure and its supporting heat dissipation method with reasonable structure, efficient heat dissipation and easy maintenance, so as to ensure the long-term stable operation of electrical equipment.

[0006] In order to achieve the above technical objectives, the present invention provides the following technical solutions:

[0007] A high-efficiency heat dissipation structure for an electrical cabinet includes an outer shell, vents, heat dissipation columns, and fins. The outer shell is rectangular in shape and made of high-strength metal or engineering plastic, offering excellent structural strength and impact resistance. The inner shell is hollow, housing electrical components and facilitating air circulation for heat dissipation. The outer shell is wall-mounted, conserving floor space and suitable for a variety of applications, including industrial control rooms, communication base stations, and power distribution rooms. Ventilation openings are provided on the left and right sides of the outer shell, forming convection ventilation channels that improve air circulation efficiency and facilitate the timely dissipation of heat within the cabinet. The heat dissipation columns are vertically mounted within the outer shell and are arranged in a uniform pattern to form a good heat conduction network. One end of each column is securely fixed to the inner wall of the outer shell, transferring heat from the surface of the electrical equipment to the exterior. Heat dissipation fins are mounted on the top of each heat dissipation column and arranged in a linear array to maximize the heat dissipation area and enhance heat exchange efficiency. The fins are installed between the two vents, forming the core heat dissipation area in the air circulation path. The heat is quickly taken away by the inlet and outlet air flow, achieving rapid diffusion and effective control of the heat inside the electrical cabinet.

[0008] The upper and lower surfaces of the shell are respectively provided with multiple air inlets for introducing external cold air to form a vertical air flow channel; at the same time, two symmetrically distributed air outlets are provided on the front of the shell to discharge the hot air inside the cabinet in time, thereby building an efficient ventilation and heat dissipation circulation system and effectively improving the overall heat dissipation efficiency.

[0009] An air inlet fan is installed inside the air inlet, and the installation direction of the air inlet fan is set to blow air from the outside to the inside, that is, to actively introduce fresh air with a relatively low temperature outside into the interior of the electrical cabinet, so as to enhance the air flow inside the cabinet and improve the cooling efficiency. The fan can continuously deliver cold air, effectively reducing the risk of local overheating in the cabinet. At the same time, an air outlet fan is also provided inside the air outlet, and the wind direction of the air outlet fan is to blow air from the inside to the outside, which is used to quickly discharge the hot air generated by the operation of the electrical components inside the electrical cabinet to the outside of the cabinet. The air inlet fan and the air outlet fan form an air circulation system that echoes each other front and back, establishing a stable forced convection ventilation path, thereby maintaining a dynamic balance of the temperature inside the electrical cabinet during the entire operation process, and ensuring that the electrical components operate efficiently and stably in a good thermal environment.

[0010] The vents are evenly distributed in the form of a rectangular array on the left and right sides of the electrical cabinet housing, which not only increases the overall ventilation area, but also facilitates the formation of a good air circulation path. The cross-section of each vent is set to an inclined structure, and the inclination direction is set downward from the inside to the outside relative to the housing. This special structural design can effectively guide the hot air in the cabinet to flow out in a specific direction, while preventing external dust, water vapor or debris from entering the cabinet in reverse, thereby improving the operating safety and stability of the equipment. The inclination angle of the vent has been optimized so that the natural wind forms a convex wind path when flowing inside the housing, that is, an air flow pattern that is high in the middle and low on both sides, which helps the air form vortices inside the cabinet to enhance heat exchange and improve the efficiency of natural heat dissipation. In the static state without turning on the fan, the structure can still rely on the thermal pressure difference to drive the formation of effective air flow, which is beneficial to energy saving and consumption reduction and maintaining stable operation of the system.

[0011] The inclination angle of the vents is designed to be between 30° and 60°. It has been verified that this angle range can effectively prevent foreign matter from entering the interior of the cabinet while ensuring ventilation efficiency, thereby improving the safety and stability of the entire structure. The inclined design not only helps to guide the direction of the airflow, but also enhances the inertial effect of the air flow and improves the heat exchange efficiency of the air in the internal space. In addition, the vents on the left and right sides of the shell are arranged in a symmetrical mirrored manner, so that the inlet and outlet airflow form a stable lateral convection path, further optimizing the air circulation structure inside the cabinet. This mirrored distribution design has good structural balance, which helps to reduce the occurrence of local overheating areas, making the temperature inside the cabinet more uniform, ensuring that the electronic components maintain a good thermal environment during long-term operation, thereby extending their service life and improving the operational reliability of the overall system.

[0012] The side of the mounting block is precisely provided with positioning holes and snap-in holes for achieving a stable connection and accurate positioning with other components. Among them, the positioning hole is arranged in a cross-shaped structure, which has good multi-directional matching capabilities, facilitates quick alignment and plug-in during installation, and reduces the time cost of manual debugging. The cross-shaped design also enhances the guidance during the installation process, preventing the components from offsetting or misaligning during the fixing process, thereby improving the installation accuracy and stability of the entire structure. The snap-in holes are cleverly arranged above the inside of the positioning holes, and are quickly fixed with the snap-in parts through structural interlocking, without the need for additional screws or tools, thereby improving assembly efficiency. The position and size of the snap-in holes have been precisely calculated, which not only ensures sufficient connection strength, but also facilitates subsequent maintenance and disassembly operations. The overall structural design is reasonable, which not only achieves precise positioning, but also has good assembly convenience and structural reliability, and is widely applicable to the installation needs of various modular equipment.

[0013] Through structural optimization design, regular cross-shaped gaps are formed between the adjacent heat dissipation fins. The gaps are provided with ventilation channels in both vertical and horizontal directions, so that air can flow freely in multiple directions, enhancing the overall convection efficiency of the heat dissipation system. This cross-shaped gap design not only increases the air circulation area, but also forms a local micro-vortex area, which helps to fully exchange hot air between the fins and further increase the heat diffusion rate. At the same time, the adjacent heat dissipation fins are arranged in a staggered manner, avoiding the blockage of the air duct that may be caused by complete overlap between the fins, making the air flow smoother. The staggered layout also effectively prevents the generation of heat dissipation dead corners, ensuring that each fin can be heated evenly and dissipate heat efficiently. The overall layout is scientific and reasonable, which can maximize the heat dissipation efficiency in a limited space. It is particularly suitable for the rapid heat release requirements when high-density components inside electrical cabinets are in operation, ensuring long-term and stable operation of the system.

[0014] The rear area inside the housing is designed as the main functional module installation area, used to fix various electronic components such as control boards, power modules, and sensor interfaces. These components continuously generate heat during operation. To avoid interference between the heat dissipation structure and the electronic components, the layout of the heat dissipation columns has been rationally planned, and an avoidance installation method is adopted to ensure effective heat dissipation without affecting the normal operation of the device. The heat dissipation columns are a multi-layer structure, with a copper column layer on the outside. This copper column layer has excellent thermal conductivity and can quickly guide internal heat to the heat dissipation fins. The copper column layer is further coated with a sparse copper powder layer. This structure forms a porous surface with dense heat conduction paths, effectively increasing the heat conduction contact area and improving heat dissipation efficiency. The sparse structure also has a certain thermal buffering effect, which can absorb high instantaneous heat in a short period of time and slowly release it, ensuring the stability of the entire heat dissipation system and the long-term safe operation of the electronic components. The overall design achieves an organic combination of heat dissipation efficiency and functional layout while maintaining a compact structure.

[0015] The internal cavity of the heat sink is injected with a high-concentration alcohol liquid. This liquid has high volatility and excellent thermal conductivity. Its volume accounts for 30% to 60% of the internal cavity volume of the heat sink. This precise ratio ensures optimal heat transfer efficiency under different temperature conditions. When the electronic components inside the electrical cabinet generate heat, the heat energy is transferred to the heat sink. The internal alcohol liquid quickly absorbs the heat and partially evaporates. As the vapor moves within the column, it transfers the heat energy to the external copper column layer and heat sink fins, achieving rapid heat conduction and release. It then condenses and refluxes, forming a stable liquid-vapor circulation heat dissipation mechanism. This design not only improves the heat dissipation response speed, but also has excellent thermal balance regulation capabilities, making it suitable for electrical equipment in environments with frequent temperature increases. Compared to traditional metal heat conduction methods, the alcohol liquid medium can more flexibly respond to sudden heat increases, reduce the risk of component overheating, and improve the safety and reliability of the overall system operation.

[0016] A method for heat dissipation of an electrical cabinet, which is used in conjunction with the above-mentioned high-efficiency heat dissipation structure of the electrical cabinet; characterized in that the method comprises the following steps:

[0017] S1: The staff installs the housing on the wall using the mounting block. They align the positioning holes on the mounting block with the hooks fixed on the wall and press the housing against the wall. After the mounting block is snapped onto the hooks, the hooks snap into the snap-in holes to complete the installation.

[0018] S2: Connect the relevant wires and data cables. During the formal use, the electronic components generate heat, which is absorbed by the heat sink fins. The heat is heated and the alcohol liquid inside the heat sink column evaporates and absorbs heat. The heat is then transferred to the heat sink fins through the heat sink column.

[0019] S3: Natural air enters the housing from the vents on one side, forms a convex air path inside the housing, and is discharged from the vents on the other side. This achieves natural air cooling for the heat sink fins, and the convex air path quickly dissipates the rising heat.

[0020] S4: When the electrical cabinet is working under heavy load and the external environment is relatively hot, start the air inlet and outlet fans. A large amount of air flows into the enclosure from the top and bottom ends, and is quickly discharged from the air outlet after passing through the heat sink fins.

[0021] S5: When the temperature is slightly higher, the air inlet fan and the air outlet fan can also be used separately to reduce energy consumption.

[0022] The beneficial effects of the present invention are as follows:

[0023] (1) The present invention significantly improves the heat dissipation efficiency inside the cabinet by reasonably arranging vents, heat dissipation columns and heat dissipation fins in the heat dissipation structure of the high-efficiency electrical cabinet. The outer shell adopts a rectangular hollow structure and is equipped with inclined rectangular vents to form a stable and efficient air circulation path, so that the hot air in the cabinet can be quickly discharged and the cold air can enter effectively, ensuring that the temperature inside the cabinet is well controlled. In particular, the mirror-symmetrical arrangement of the vents and their specific tilt angle design not only enhance the natural convection effect, but also effectively block the entry of external dust and impurities, thereby extending the service life of the equipment. The scientific layout of the heat dissipation columns and heat dissipation fins, as well as the cross-shaped staggered distribution of the gap structure, further enhance the air convection heat exchange capacity, avoid heat dissipation dead corners, and make the entire heat dissipation system more uniform and efficient.

[0024] (2) The present invention innovatively injects high-concentration alcohol liquid into the heat dissipation column, and utilizes the good volatility and thermal conductivity of alcohol to construct a liquid-gas phase change heat dissipation mechanism, thereby achieving rapid absorption and conduction of heat. The multi-layer composite structure design of the copper column layer and the sparse copper powder coating not only enhances the heat conduction efficiency, but also improves the thermal stability and durability of the structure. This design can effectively alleviate the performance degradation and safety hazards of electronic components caused by temperature increases, and improve the overall operational reliability and stability of the electrical cabinet. Overall, the present invention solves the problem of insufficient heat dissipation in traditional electrical cabinets through structural optimization and material innovation. It is suitable for the heat dissipation needs of various high-density electronic equipment and has broad application prospects and significant economic and social benefits.

[0036] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0037] like Figure 1-8 The figure shows a high-efficiency heat dissipation structure for an electrical cabinet, comprising a housing 1, vents 3, heat dissipating columns 7, and heat dissipating fins 8. The housing 1 is generally rectangular in shape and made of high-strength metal or engineering plastic, offering excellent structural strength and impact resistance. The interior of the housing 1 is hollow, housing electrical components and facilitating air circulation for heat dissipation. The housing 1 is wall-mounted, conserving floor space and suitable for a variety of applications, such as industrial control rooms, communication base stations, and power distribution rooms. Vents 3 are provided on the left and right sides of the housing 1, forming convection ventilation channels that improve air circulation efficiency and facilitate the timely removal of heat from the cabinet. The heat dissipating columns 7 are vertically mounted within the housing 1 and are arranged in a uniform pattern to form a good heat conduction network. One end of each heat dissipating column 7 is securely fixed to the inner wall of the housing 1, transferring heat from the electrical equipment to the exterior. Heat dissipating fins 8 are mounted above each heat dissipating column 7 and arranged in a linear array to maximize the heat dissipation area and enhance heat exchange efficiency. The fin is installed between the two vents 3, forming the core heat dissipation area in the air circulation path. The heat is quickly taken away by the inlet and outlet air flow, thereby achieving rapid diffusion and effective control of the heat inside the electrical cabinet.

[0038] like Figure 1 As shown, the upper and lower surfaces of the shell 1 are respectively provided with a plurality of air inlets 11 for introducing external cold air to form a vertical air flow channel; at the same time, two symmetrically distributed air outlets 12 are provided in the front of the shell 1 to discharge the hot air inside the cabinet in time, thereby constructing an efficient ventilation and heat dissipation circulation system and effectively improving the overall heat dissipation efficiency.

[0039] like Figure 1As shown, an air inlet fan 4 is installed inside the air inlet 11, and the installation direction of the air inlet fan 4 is set to blow air from the outside to the inside, that is, the relatively low-temperature fresh air outside is actively introduced into the interior of the electrical cabinet to enhance the air flow and cooling efficiency inside the cabinet. The fan can continuously deliver cold air, effectively reducing the risk of local overheating in the cabinet. At the same time, an air outlet fan 5 is also provided inside the air outlet 12, and the wind direction of the air outlet fan 5 is blowing from the inside to the outside, which is used to quickly discharge the hot air generated by the operation of the electrical components inside the electrical cabinet to the outside of the cabinet. The air inlet fan 4 and the air outlet fan 5 form an air circulation system that echoes each other front and back, and establish a stable forced convection ventilation path, so as to maintain the dynamic balance of the temperature inside the electrical cabinet during the entire operation process, and ensure that the electrical components operate efficiently and stably in a good thermal environment.

[0040] like Figure 2-3 As shown, the vents 3 are evenly distributed in the form of a rectangular array on the left and right sides of the electrical cabinet housing 1, which not only increases the overall ventilation area, but also facilitates the formation of a good air circulation path. The cross-section of each vent 3 is set to an inclined structure, and the inclination direction is set downward from the inside to the outside relative to the housing 1. This special structural design can effectively guide the hot air in the cabinet to flow out in a specific direction, while preventing external dust, water vapor or debris from entering the cabinet in reverse, thereby improving the operating safety and stability of the equipment. The inclination angle of the vent 3 has been optimized so that the natural wind forms a convex wind path when flowing inside the housing 1, that is, an air flow pattern with a high middle and low sides, which helps the air form vortices inside the cabinet to enhance heat exchange and improve the efficiency of natural heat dissipation. In the static state without turning on the fan, the structure can still rely on the thermal pressure difference to drive the formation of effective air flow, which is beneficial to energy saving and consumption reduction and maintaining stable operation of the system.

[0041] The inclination angle of the vents 3 is designed to be between 30° and 60°. It has been verified that this angle range can effectively prevent foreign matter from entering the interior of the cabinet while ensuring ventilation efficiency, thereby improving the safety and stability of the entire structure. The inclined design not only helps to guide the direction of the airflow, but also enhances the inertial effect of the air flow and improves the heat exchange efficiency of the air in the internal space. In addition, the vents 3 on the left and right sides of the outer shell 1 are arranged in a symmetrical mirror manner, so that the inlet and outlet airflows form a stable lateral convection path, further optimizing the air circulation structure inside the cabinet. This mirror distribution design has good structural balance, helps to reduce the generation of local overheating areas, makes the temperature inside the cabinet more uniform, and ensures that the electronic components 6 maintain a good thermal environment during long-term operation, thereby extending their service life and improving the operational reliability of the overall system.

[0042] like Figure 5As shown, the side of the mounting block 2 is precisely provided with positioning holes 21 and snap-in holes 22 for achieving a stable connection and accurate positioning with other components. Among them, the positioning hole 21 is set as a cross-shaped structure, which has good multi-directional matching capabilities, facilitates quick alignment and plug-in during installation, and reduces the time cost of manual debugging. The cross-shaped design also enhances the guidance during the installation process, prevents the components from being offset or misplaced during the fixing process, thereby improving the installation accuracy and stability of the entire structure. The snap-in hole 22 is cleverly arranged above the inside of the positioning hole 21, and is quickly fixed with the snap-in component through structural interlocking, without the need for additional screws or tools, thereby improving assembly efficiency. The position and size of the snap-in hole 22 have been precisely calculated, which not only ensures sufficient connection strength, but also facilitates subsequent maintenance and disassembly operations. The overall structural design is reasonable, which not only achieves precise positioning, but also has good assembly convenience and structural reliability, and is widely applicable to the installation needs of various modular equipment.

[0043] like Figure 4 、 5 As shown in Figure 7, the adjacent heat dissipation fins 8 are designed through structural optimization to form regular cross-shaped gaps. The gaps are provided with ventilation channels in both vertical and horizontal directions, so that air can flow freely in multiple directions, thereby enhancing the overall convection efficiency of the heat dissipation system. This cross-shaped gap design not only increases the air circulation area, but also forms a local micro-eddy current area, which helps to fully exchange hot air between the fins and further increase the heat diffusion rate. At the same time, the adjacent heat dissipation fins 8 are arranged in a staggered manner, avoiding the air duct blockage phenomenon that may be caused by complete overlap between the fins, making the air flow smoother. The staggered layout also effectively prevents the generation of heat dissipation dead corners, ensuring that each fin can be evenly heated and dissipate heat efficiently. The overall layout is scientific and reasonable, and can maximize the heat dissipation efficiency in a limited space. It is particularly suitable for the rapid heat release requirements when high-density components inside electrical cabinets are in operation, ensuring long-term stable operation of the system.

[0044] The rear area inside the housing 1 is designed as the main functional module installation area, used to fix various electronic components 6, such as control boards, power modules, and sensor interfaces. These components continuously generate heat during operation. To avoid interference between the heat dissipation structure and the electronic components 6, the layout of the heat dissipation columns 7 has been rationally planned, adopting an avoidance installation method to ensure effective heat dissipation without affecting the normal operation of the device. The heat dissipation columns 7 are multi-layered, with the outer surface coated with a layer of copper columns 71. This copper column layer 71 has excellent thermal conductivity and can quickly guide internal heat to the heat dissipation fins 8. The interior of the copper column layer 71 is further coated with a layer of copper powder 72 with a sparse structure. This structure forms a porous surface with dense heat conduction paths, effectively increasing the heat conduction contact area and improving heat dissipation efficiency. The sparse structure also has a certain thermal buffering effect, which can absorb high instantaneous heat in a short period of time and slowly release it, ensuring the stability of the entire heat dissipation system and the long-term safe operation of the electronic components 6. The overall design achieves an organic unity of heat dissipation efficiency and functional layout while maintaining a compact structure.

[0045] like Figure 6 As shown, the internal cavity of the heat dissipation column 7 is injected with a high-concentration alcohol liquid. This liquid has high volatility and excellent thermal conductivity. Its volume accounts for 30% to 60% of the internal cavity volume of the heat dissipation column 7. Through precise proportioning, it ensures that the best heat transfer efficiency is maintained under different temperature conditions. When the electronic components 6 inside the electrical cabinet generate heat during operation, the heat energy is transferred to the heat dissipation column 7. The internal alcohol liquid quickly absorbs the heat and partially evaporates. During the movement of the steam in the column, the heat energy is transferred to the external copper column layer 71 and the heat dissipation fins 8, achieving rapid heat conduction and release. It is then condensed and refluxed to form a stable liquid-vapor circulation heat dissipation mechanism. This design not only improves the heat dissipation response speed, but also has excellent thermal balance regulation capabilities. It is suitable for electrical equipment in environments with frequent temperature rises. Compared with traditional metal heat conduction methods, the alcohol liquid medium can more flexibly respond to sudden heat increases, reduce the risk of component overheating, and improve the safety and reliability of the overall system operation.

[0046] like Figure 8 As shown, a method for heat dissipation of an electrical cabinet is used in conjunction with the above-mentioned high-efficiency heat dissipation structure of the electrical cabinet; the method is characterized in that the steps of the method are as follows:

[0047] S1: The worker installs the housing 1 on the wall through the mounting block 2, aligns the positioning hole 21 on the mounting block 2 with the hook fixed on the wall, presses the housing 1 against the wall, and after the mounting block 2 is engaged with the hook, the hook is engaged with the engaging hole 22 to complete the installation;

[0048] S2: Connect the relevant wires and data cables. During the formal use, the electronic components 6 generate heat, which is absorbed by the heat sink fins 8 in large quantities and heats the alcohol liquid inside the heat sink 7 to evaporate and absorb heat. The heat is then dissipated and conducted to the heat sink fins 8 through the heat sink 7.

[0049] S3: Natural wind enters the housing 1 from the vent 3 on one side of the housing 1, forms a convex wind path inside the housing 1, and is discharged from the vent 3 on the other side, achieving natural wind heat dissipation for the heat sink 8, and the convex wind path quickly dissipates the rising heat;

[0050] S4: When the electrical cabinet is working under heavy load and the external environment is relatively hot, the air inlet fan 4 and the air outlet fan 5 are started, and a large amount of flowing air enters the interior of the housing 1 from the upper and lower ends, and is quickly discharged from the air outlet 12 after passing through the heat dissipation fins 8;

[0051] S5: When the temperature is slightly higher, the air inlet fan 4 and the air outlet fan 5 can also be used separately to reduce energy consumption.

[0052] During operation, the present invention first securely mounts the electrical cabinet's housing 1 on the wall using the mounting block 2. Specifically, the operator aligns the positioning holes 21 on the mounting block 2 with the hooks already fixed on the wall. The housing 1 is then firmly pressed against the wall, allowing the mounting block 2 to engage the hooks. The hooks then engage the engaging holes 22 in the mounting block 2, completing the secure installation of the housing 1. This ensures the cabinet is secure and facilitates subsequent maintenance.

[0053] Afterward, the staff connected the electrical wiring and data cables inside the electrical cabinet, and normal operation began. The electronic components 6 within the cabinet generate a large amount of heat during operation, which is first absorbed by the internally mounted heat sink fins 8. Through close contact with the heat sink fins 7, the heat sink fins 8 transfer the heat to the highly concentrated alcohol liquid inside the heat sink fins 7. The alcohol liquid evaporates in response to the heat, absorbing a large amount of heat energy. This achieves internal liquid-to-gas phase change heat dissipation, effectively reducing the component temperature. Simultaneously, the heat is rapidly conducted and diffused through the heat sink fins 7 and the heat sink fins.

[0054] During the natural convection cooling phase, vents 3 on one side of the housing 1 draw in outside air, which forms a convex air path within the cabinet, forcing the hot air to rise along a specific path and be exhausted through vents 3 on the other side. This natural convection mechanism effectively utilizes ambient wind force to help the heat sink fins 8 dissipate heat faster, improving heat dissipation efficiency.

[0055] When the electrical cabinet is heavily loaded or the ambient temperature is high, the system automatically activates inlet fan 4 and outlet fan 5 to enhance air flow. A large amount of cold air enters from the upper and lower ends of the housing 1, absorbs heat through the heat sink fins 8, and is quickly exhausted, forming a forced ventilation cycle, accelerating heat dissipation and ensuring stable equipment operation.

[0056] Furthermore, for energy conservation, when temperatures are slightly higher, inlet fan 4 and outlet fan 5 can operate independently, reducing energy consumption while still maintaining effective heat dissipation, achieving intelligent and efficient heat dissipation management. This integrated workflow ensures that the electrical cabinet maintains excellent heat dissipation performance under various operating conditions, ensuring equipment safety and reliability.

[0057] Various modifications to the present disclosure will be apparent to those skilled in the art, and the general principles defined herein may be applied to other variations without departing from the scope of the present disclosure. Therefore, the present disclosure is not limited to the examples and designs described herein, but should be given the widest scope consistent with the principles and novel features disclosed herein.

10. A method for heat dissipation of an electrical cabinet, the method being used in conjunction with a high-efficiency heat dissipation structure for an electrical cabinet according to any one of claims 1 to 9; characterized in that: The steps of the method are as follows: S1: The staff installs the housing (1) on the wall through the mounting block (2), aligns the positioning hole (21) on the mounting block (2) with the hook fixed on the wall, presses the housing (1) toward the wall, and after the mounting block (2) is snapped onto the hook, the hook is snapped into the snap-in hole (22) to complete the installation; S2: Connect the relevant wires and data cables. During the formal use, the electronic components (6) generate heat during operation, which is absorbed by the heat dissipation fins (8) in large quantities and heats the alcohol liquid inside the heat dissipation column (7) to evaporate and absorb heat. The heat is then transferred to the heat dissipation fins (8) through the heat dissipation and heat dissipation column (7). S3: Natural wind enters the interior of the housing (1) from the vent (3) on one side of the housing (1), forms a convex wind path inside the housing (1), and is discharged from the vent (3) on the other side, achieving natural wind heat dissipation for the heat dissipation fins (8), and relying on the convex wind path to quickly conduct the rising heat; S4: When the electrical cabinet is working at a high workload and the external environment is relatively hot, the air inlet fan (4) and the air outlet fan (5) are started, and a large amount of flowing air enters the interior of the housing (1) from the upper and lower ends, and is quickly discharged from the air outlet (12) after passing through the heat dissipation fins (8); S5: When the temperature is slightly higher, the air inlet fan (4) and the air outlet fan (5) can also be used separately, thereby reducing energy consumption.
