[0095] The cabinet body 310 is installed between the two support assemblies 321 and also supported by the two support beams 322. The two support assemblies 321 can be the same or not completely the same, and when not completely the same, they generally have design differences according to the actual installation conditions. Correspondingly, the two support beams 322 can be the same or have design differences, and the adjacent support beams 322 and support assemblies 321 are perpendicular to each other, and the connection mode can be bolted or welded, thereby forming a stable cubic structure.

[0099] It can be understood that the first connecting pieces 324 can strengthen the connection between the upright columns 323, improve the structural strength and stability of the entire support assembly 321, and also can be used for transmitting or dispersing forces or pressures from the upright columns 323 or other parts.

[0100] In some embodiments, as shown in FIG. 3, the box body 30 can further include a top cover 330, the outer plate at the top of the box body 30 has an opening, and the top cover 330 is arranged on the opening, and the fan is installed in the top cover 330.

[0102] The main function of the fan is to dissipate heat for the equipment inside the box body 30, the fan is installed in the top cover 330 and can directly exchange gas with the inside of the box body 30 through the opening, and exchange gas with the external environment through the top cover 330, the operation of the fan can accelerate the air flow between the inside of the box body 30 and the external environment, thereby enhancing the heat dissipation efficiency of the system, reducing the temperature inside the box body 30, and maintaining the normal operation of the equipment inside the box body 30.

[0103] It can be understood that through the cooperation of the box 30, the top cover 330 and the fan, an integrated system with ventilation and heat dissipation functions can be formed, thereby further improving the heat dissipation performance of the box 30, maintaining the normal operation of the electrical equipment 1, and also making the box 30 more easy to maintain and manage, improving the reliability and availability of the system.

[0104] The box 30 is provided with a first air port and a second air port communicating with the second cavity 302, wherein the first air port and the second air port can be at least one of the following structural forms:

The second cavity 302 exchanges gas and heat with the external area of the box 30 through the first air port, and exchanges gas and heat with the external area of the top cover 330 through the second air port.

[0108] The positions and sizes of the first air port and the second air port are determined according to the specific structure of the box 30 and the top cover 330 and the requirements of the internal equipment, and are usually designed at positions that can maximize the ventilation effect and do not hinder other functional components. The first air port and the second air port allow gas to flow, but when ventilation is not needed, they can maintain a certain sealing property to reduce the risk of dust and foreign matter entering the second cavity 302.

[0109] The first air port and the second air port can achieve ventilation and heat dissipation of the second cavity 302, and the fan is used to dissipate heat for the condenser 110 (shown in FIG. 17). Through the operation of the fan, the flow of gas between the second cavity 302 and the external environment can be accelerated, the temperature in the second cavity 302 can be reduced, and the normal operation of the internal equipment can be ensured. The first air port and the second air port form an air duct when the fan is running, and the inlet and outlet of the air duct can be exchanged to provide multiple gas flow modes.

[0119] The positions and sizes of the first air port and the second air port are determined according to the specific structure of the cabinet 30 and the requirements of the internal equipment, and are usually designed at positions that can maximize the ventilation effect and do not hinder other functional components. The first air port and the second air port allow gas to flow, but can maintain a certain sealing property when ventilation is not required, so as to reduce the entry of dust, foreign matter, etc. into the second cavity 302.

[0120] The arrangement of the first air port and the second air port can achieve ventilation and heat dissipation of the second cavity 302. The fan is used to dissipate heat for the condenser 110. Through the operation of the fan, the flow of gas between the second cavity 302 and the external environment can be accelerated, the temperature in the second cavity 302 is reduced, and the normal operation of the internal equipment is maintained. The first air port and the second air port form an air duct when the fan is operating. The inlet and outlet of the air duct can be exchanged to provide multiple gas flow modes.

[0121] As shown in FIGS. 12 and 13, the first outer plate 341 and the third outer plate 343 of the cabinet 30 are oppositely arranged along the first direction, respectively. The air duct of the second cavity 302 can enter from the first air port on the third outer plate 343 of the cabinet 30 and exit from the second air port on the first outer plate 341 of the cabinet 30, or the inlet and outlet of the air duct can be exchanged, and the air duct can enter from the second air port on the first outer plate 341 of the cabinet 30 and exit from the first air port on the third outer plate 343 of the cabinet 30.

[0122] It can be understood that, by adopting the above structure, the first air port and the second air port are both arranged on the cabinet 30, which can reduce the additional top cover 330 or other structures, make the overall design more compact, and simplify the maintenance and cleaning process.

[0123] In some embodiments, the second cavity 302 includes multiple sections located outside adjacent two wall surfaces of the cabinet body 310.

[0124] The multiple sections located outside adjacent two wall surfaces of the cabinet body 310 refer to the space between the wall surface of the cabinet body 310 and the outer plate of the cabinet 30. The cabinet 30 and the cabinet body 310 are both cuboids, and the size of the cabinet body 310 is smaller than that of the cabinet 30 in different directions. The space between the wall surface of the cabinet body 310 and the outer plate of the cabinet 30 is the remaining space of the large cuboid except for the small cuboid. The multi-section second cavity 302 can provide installation space for the heat dissipation device 10, reduce the contact between the outer plate 340 of the cabinet 30 and the cabinet body 310, and can be arranged with various air ducts to more effectively control the heat transfer, or adjust the heat insulation or heat dissipation performance of different regions according to the temperature change of the external environment of the cabinet, so as to maintain the stability of the internal temperature of the cabinet 30.

[0125] In some cases, the second cavity 302 can also serve as an additional structural support to enhance the overall stability and strength of the cabinet 30, or in environments where the cabinet 30 can be subjected to external impacts or vibrations, the multi-segmented second cavity 302 can also absorb some of the impact energy and reduce damage to the cabinet body 310 and the internal equipment.

[0126] It can be understood that the second cavity 302 includes multiple segments located adjacent to two wall surfaces of the cabinet body 310, which can provide more functions for the cabinet 30 to adapt to different environments.

[0127] In some embodiments, as shown in FIGS. 1 and 3, the outer plate 340 includes a first outer plate 341, a second outer plate 342, a third outer plate 343, a fourth outer plate 344, and a fifth outer plate 345. The outer plate 340 can be designed with ventilation holes, handles, maintenance windows, or interface panels, etc. to facilitate heat dissipation, connection of external devices, or handling.

[0128] The first outer plate 341 and the third outer plate 343 are arranged opposite to each other along a first direction, i.e. the first outer plate 341 is located at the front side of the cabinet 30, and the third outer plate 343 is located at the rear side of the cabinet 30. The second outer plate 342 and the fourth outer plate 344 are arranged opposite to each other along a second direction, i.e. the second outer plate 342 is located at the left side of the cabinet 30, and the fourth outer plate 344 is located at the right side of the cabinet 30. The areas of the second outer plate 342 and the fourth outer plate 344 are both larger than the areas of the first outer plate 341 and the third outer plate 343, so as to increase the heat dissipation efficiency and provide additional support structure.

[0129] The fifth outer plate 345 is arranged opposite to the support beam 322 of the support frame 320 along a third direction, i.e. the fifth outer plate 345 is located at the top of the cabinet 30, and is perpendicular to the four aforementioned outer plates 340. The fifth outer plate 345 can be designed with ventilation holes to provide a heat dissipation air duct.

[0130] It can be understood that the plurality of outer plates 340 collectively constitute the external structure of the cabinet 30, which can protect the equipment inside the cabinet 30 and meet the needs of heat dissipation, connection, etc. through specific layout and functional design.

[0131] In some embodiments, the second outer plate 342 is connected to the column 323 of the support frame 320 on the same side at both ends along the first direction, and is connected to the fifth outer plate 345 and the support beam 322 of the support frame 320 on the same side at both ends along the third direction, respectively. The fourth outer plate 344 is connected to the column 323 of the support frame 320 on the same side at both ends along the first direction, and is connected to the fifth outer plate 345 and the support beam 322 of the support frame 320 on the same side at both ends along the third direction, respectively.

[0132] The second outer plate 342 is connected to the column 323 of the support frame 320 at one end close to the first outer plate 341 in the first direction, and is connected to the support beam 322 of the support frame 320 at the other end away from the fifth outer plate 345. The first outer plate 341 and the third outer plate 343 are detachably connected to the support frame 320.

[0133] The second outer plate 342 is connected to the column 323 of the support frame 320 at one end close to the third outer plate 343 in the first direction, and is connected to the support beam 322 of the support frame 320 and the fifth outer plate 345 at the two ends in the third direction, respectively. The fourth outer plate 344 is composed of a fourth upper plate 344a and a fourth lower plate 344b, and can be firmly fixed on the box body 310. The top of the fourth upper plate 344a is connected to the fifth outer plate 345, and the bottom of the fourth lower plate 344b is connected to the support beam 322 of the support frame 320,

[0134] The connection between the second outer plate 342 and the support assembly 321 and the support beam 322 is screw connection, which can provide strong connection force and reliability to improve the firmness of the connection.

[0135] The two ends of the first outer plate 341 in the second direction are connected to the columns 323 of the same side of the support frame 320, and one end of the first outer plate 341 in the third direction is connected to the first connecting piece 324 at the top of the same side of the support frame 320. The two ends of the third outer plate 343 in the second direction are connected to the columns 323 of the same side of the support frame 320, and one end of the third outer plate 343 in the third direction is connected to the first connecting piece 324 at the top of the same side of the support frame 320. The two ends of the fifth outer plate 345 in the first direction are connected to the first connecting piece 324 at the top of the same side of the support frame 320.

[0136] The first outer plate 341 and the third outer plate 343 are detachably connected to the support frame 320 through the clamping structure, which is convenient for maintenance or replacement. Clamping is a quick and easy connection method, which usually uses the friction force or elastic deformation between two or more components to maintain the connection state. The clamping connector is usually designed with special buckles, clamping grooves or flanges, etc. to achieve quick connection and disassembly.

[0137] It can be understood that the connection mode of the plurality of outer plates with the support frame 320 and the box body 310 has a certain influence on the overall structural stability and reliability of the box body 30. By adopting different connection modes such as screw connection and clamping, the design of the box body 30 can be optimized according to the specific application scene and requirements to improve its performance and effect in actual use.

[0138] In some embodiments, as shown in FIG. 18, the wall surface of the box body 310 facing the first outer plate 341 and the third outer plate 343 is provided with a detachable maintenance window 360, which can be used to maintain and repair the internal equipment without completely opening or moving the entire box 30, thereby improving the maintainability and operation efficiency of the equipment.

[0139] The maintenance window 360 is located on the wall surface of the box body 310 facing the first outer plate 341 and the third outer plate 343 and is easily accessible. The shape of the maintenance window 360 can be rectangular, circular or other suitable shape, depending on the design requirements and space limitations. The maintenance window 360 is designed to be easily detachable and reattachable, so that it can be quickly opened and closed when needed. It can be installed on the wall surface of the box body 310 by bolt connection, buckle connection or hinge connection, etc. The maintenance window 360 can also use sealing materials such as gaskets and sealants to ensure good sealing when closed, thereby reducing the risk of external factors such as dust and moisture entering the interior of the box 30.

[0140] It can be understood that the wall surface of the box body 310 facing the first outer plate 341 and the third outer plate 343 is provided with a detachable maintenance window 360, which can improve the maintainability and operation efficiency of the equipment.

[0141] In some embodiments, as shown in FIGS. 1 and 8, the box 30 can also include a handle mounting structure. The second outer plate 342 and the fourth outer plate 344 are each provided with an escape hole 350. A part of the handle mounting structure passes through the escape hole 350 and is connected to the support beam 322 of the support frame 320, which can enhance the portability and operation convenience of the box 30.

[0142] The handle mounting structure is stable enough to withstand the weight of the box 30 and its internal equipment, reducing the risk of loosening or falling off during transportation. By mounting the handle mounting structure through the escape hole 350 to the support beam 322 of the support frame 320, its stability can be increased. The handle mounting structure needs to be compatible with the type of handle selected. Common types of handles include fixed handles, folding handles and telescopic handles, etc.

[0143] The escape hole 350 is reserved on the second outer plate 342 and the fourth outer plate 344 for the installation of the handle mounting structure. The handle mounting structure can include connecting plates, fixing bolts and gaskets, etc. The connecting plates are used to connect to the support beam 322 of the support frame 320. The fixing bolts are used to fix the connecting plates to the box 30. The gaskets are used to increase the stability and sealing of the connection,

[0144] It can be understood that by providing the escape hole 350 on the second outer plate 342 and the fourth outer plate 344, and connecting the handle mounting structure to the support beam 322 of the support frame 320 through the escape hole 350, the portability and operation convenience of the box body 30 can be significantly improved, which helps to carry and move the box body 30 and reduces the difficulty and risk in the carrying process.

[0145] The embodiment of the present application also provides an electrical equipment 1.

[0146] As shown in FIG. 14 and FIG. 15, the electrical equipment 1 comprises a box body 30 and a radiator 10.

[0147] The box body 30 forms a first cavity 301 and a second cavity 302 which are isolated from each other, and the second cavity 302 is in communication with the outside.

[0148] The box body 30 is used for accommodating and separating different components, and isolates the first cavity 301 and the second cavity 302 from each other, so that the heat and gas between the two cavities are not exchanged at will. The box body 30 can be made of suitable materials such as metal or plastic materials to maintain the isolation effect between the first cavity 301 and the second cavity 302.

[0149] It can be understood that the first cavity 301 and the second cavity 302 are respectively used for accommodating different components to realize different functions. The first cavity 301 is mainly used for accommodating power devices, and the environmental conditions such as temperature, pressure and humidity can be independently controlled and are not affected by the external environment. The second cavity 302 is used for accommodating the radiator 10 and the fan, and is in communication with the outside, so it will be affected by the external environment, but it will not affect the environment in the first cavity 301.

[0150] The radiator 10 comprises a condenser 110 and an evaporator 120, and a gas pipe 130 and a liquid pipe 140 which are in communication between the condenser 110 and the evaporator 120. The condenser 110 is installed in the second cavity 302, and the evaporator 120 has a first face facing the first cavity 301.

[0151] In the technical solution of the present application, the condenser 110 is installed in the second cavity 302 which is in communication with the outside, and the main function is to cool the gas and convert it into liquid. It is usually used to transfer the heat energy absorbed by the refrigerant in the evaporator 120 to the cooling medium, so as to reduce the system temperature. The cooling medium can be air, which is cooled by the fan installed near the condenser 110. The evaporator 120 comprises a first face and a second face. The first face faces the first cavity 301 and is in contact with the first cavity 301. The second face is located in the second cavity 302 and is in communication with the condenser 110 through the gas pipe 130 and the liquid pipe 140.

[0152] It can be understood that the gas pipe 130 and the liquid pipe 140 are connected between the condenser 110 and the evaporator 120, and the refrigerant absorbs heat to evaporate into gas in the evaporator 120, then flows into the condenser 110 through the gas pipe 130 to release heat and condense into liquid, and finally returns to the evaporator 120 through the liquid pipe 140, to complete a complete refrigeration cycle, which is repeated continuously to maintain the normal operation of the refrigeration system.

[0153] According to the electrical equipment 1 of the embodiment of the present application, the cabinet 30 is divided into the first cavity 301 and the second cavity 302 which are isolated from each other, so that the isolation effect can be achieved, and heat cannot be randomly transmitted between the first cavity 301 and the second cavity 302, but is transmitted to the evaporator 120 through heat conduction or convection. Meanwhile, the first cavity 301 and the second cavity 302 can be used to accommodate different components respectively, so that the equipment in the cabinet 30 can be protected from the influence of the external environment, and the heat dissipation efficiency of the condenser 110 is improved.

[0154] In some embodiments, as shown in FIGS. 16 and 17, the electrical equipment 1 further comprises a reinforcing structure 20, and the reinforcing structure 20 forms the first mounting position 240 and the second mounting position 250, and the evaporator 120 is mounted in the first mounting position 240, and the condenser 110 is mounted in the second mounting position 250.

[0155] The reinforcing structure 20 is used to mount the heat sink 10, and the heat sink 10 comprises the evaporator 120 and the condenser 110 which are connected to each other, and the reinforcing structure 20 forms the first mounting position 240 for mounting the condenser 110 and the second mounting position 250 for mounting the evaporator 120, so that the stability and strength of the overall structure can be improved, and the reinforcing structure 20 can support and stabilize the heat sink 10, so that the heat sink 10 is stable and does not shake, and the influence of vibration on the equipment is reduced.

[0156] The reinforcing structure 20 is an integral outer frame which is composed of a plurality of components, and the components can be connected by welding, bolts, buckles and the like, and the reinforcing structure 20 can be made of high-temperature-resistant materials such as stainless steel and aluminum alloy, so as to improve the stability of the mounting position, reduce loosening or damage caused by the weight of the heat sink 10, working vibration or external environmental factors such as wind pressure and temperature change, and the reinforcing structure 20 clearly divides the first mounting position 240 and the second mounting position 250, which is helpful to realize the orderly layout of the internal components of the heat dissipation system.

[0157] The evaporator 120 and the condenser 110 are key components in the heat sink 10, and are respectively responsible for heat absorption and release, and the reinforcing structure 20 provides special mounting positions for the evaporator 120 and the condenser 110, which is helpful to optimize the layout and relative position of the heat sink 10, so as to improve the heat exchange efficiency of the entire heat dissipation system.

[0158] It can be understood that by providing the first mounting position 240 and the second mounting position 250 for the condenser 110 and the evaporator 120 of the heat sink 10 respectively through the reinforcing structure 20, the space layout can be optimized, the relative positions of the condenser 110 and the evaporator 120 are maintained, the reinforcing structure 20 plays a role in supporting and stabilizing the heat sink 10, the heat sink 10 is maintained stable and not shaken, the structural strength is enhanced, the influence of vibration on the equipment is reduced, and the heat dissipation efficiency and stability of the entire heat sink 10 are improved, and the structure of the heat sink 10 is regular, facilitating processing, transportation and assembly.

[0159] In some embodiments, as shown in FIGS. 16 and 17, the reinforcing structure 20 includes the mounting frame 210 and the oppositely arranged support 230.

[0160] The mounting frame 210 forms the first mounting position 240 for mounting the condenser 110 and plays a role in protecting the condenser 110 from damage from the external environment.

The support 230 is connected to the mounting frame 210 and is used to further support and fix the evaporator 120. The support 230 is usually oppositely arranged to provide stable support for the evaporator 120 components, reduce movement or looseness of the heat sink 10 after installation, and at the same time, not too many supports 230 are arranged in the key heat dissipation area to reduce the influence on the heat dissipation effect of the heat sink 10, which helps to maintain the long-term stable operation of the heat sink 10.

[0162] The support 230 extends along the distribution direction of the evaporator 120 and the condenser 110, i.e. the third direction, and the oppositely arranged supports 230 are connected to the mounting frame 210 to form the second mounting position 250, which also plays a role in supporting and stabilizing the evaporator 120. The support 230 can be made of metal or other solid materials to withstand the weight of the evaporator 120 and the condenser 110 and various forces and vibrations during operation.

[0163] It can be understood that the mounting frame 210 and the oppositely arranged support 230 in the reinforcing structure 20 together constitute a stable and adjustable frame system for mounting and supporting the heat sink 10, maintaining its stable operation and meeting the heat dissipation requirements.

[0164] In some embodiments, as shown in FIGS. 16 and 17, the mounting frame 210 includes oppositely arranged mounting plates 211, and the oppositely arranged supports 230 are connected to the oppositely arranged mounting plates 211 one by one.

[0165] The mounting plates 211 are the main body parts of the mounting frame 210, which are oppositely arranged to form a stable support plane, and are usually made of metal or other strong and durable materials, and can be flat plate structures to enable them to bear the weight and stress of the heat sink 10 and its components during operation.

[0166] The oppositely arranged supports 230 are connected to the oppositely arranged mounting plates 211 one by one to provide sufficient space for mounting the heat sink 10 and to improve the overall stability and rigidity of the mounting frame 210, and the connection between the supports 230 and the mounting plates 211 can be direct connection or indirect connection, direct connection usually uses fasteners to directly fix the supports 230 on the mounting plates 211, such as fixing one end of the support 230 on the mounting plate 211 by bolts and nuts, and indirect connection uses additional connecting plates, brackets or frames to transfer and disperse stress to improve the stability of the connection.

[0167] It can be understood that the mounting frame 210 is connected by oppositely arranged mounting plates 211 and one-to-one corresponding supports 230, which can provide a stable, flexible and easy-to-maintain frame for the installation of the heat sink 10, and can effectively reduce the vibration and stress generated by the heat sink 10 during operation.

[0168] In some embodiments, as shown in FIGS. 16 and 17, the mounting frame 210 further comprises at least one second connecting piece 212, which is connected between the oppositely arranged mounting plates 211.

[0169] The mounting plates 211 are the main components of the mounting frame 210, which are usually oppositely arranged to provide a mounting base for the condenser 110 components, and the second connecting piece 212 is a component mounted between the mounting plates 211 for firmly connecting the oppositely arranged mounting plates 211 together, and the second connecting piece 212 together with the mounting plates 211 forms a stable overall structure that can bear the weight and vibration of the condenser 110 and its components during operation, while fixing the relative positions between the mounting plates 211 to reduce movement or deformation during installation and use. The second connecting piece 212 also adopts appropriate anti-loosening design, such as locking washers, thread locking agents, etc., to reduce loosening caused by vibration or temperature changes during use.

[0170] It can be understood that the second connecting piece 212 is connected between the oppositely arranged mounting plates 211 to form a stable overall structure, which can fix the relative positions between the mounting plates 211 to reduce movement or deformation during installation and use, not only can enhance the structural stability of the mounting frame 210, but also can simplify the installation and maintenance process of the heat sink 10.

[0171] In some embodiments, as shown in FIGS. 16 and 17, the reinforcing structure 20 further comprises connecting beams 220 connected between oppositely arranged support members 230.

[0172] The connecting beams 220 are structural elements spanning between the oppositely arranged support members 230, used to connect the plurality of support members 230 to form an integral structure, improving the stability and rigidity between the support members 230, and also enhancing the strength of the entire reinforcing structure 20, helping to better disperse and resist the load and stress from the heat sink 10.

[0173] The connecting beams 220 form additional connection points between the support members 230, which help to disperse stress to the entire reinforcing structure 20, optimizing the stress distribution of the reinforcing structure 20, reducing the risk of damage due to stress concentration, so that the reinforcing structure 20 can better resist external load and vibration, improving the stability and safety of the heat sink 10 during operation.

[0174] It can be understood that the connecting beams 220, as an important component of the reinforcing structure 20, are used to connect oppositely arranged support members 230, which can enhance the stability and rigidity of the mounting frame 210 and optimize the stress distribution.

[0175] The embodiments of the present application will be described in detail from two different implementation angles respectively.

[0176] Example one, the first air inlet is arranged on the outer plate of the cabinet 30, and the second air inlet is arranged on the top cover 330

[0177] The electrical equipment 1 comprises a cabinet 30 and a heat sink 10, and the cabinet 30 comprises a cabinet body 310, a support frame 320 and a top cover 330.

[0178] The cabinet body 310 is provided with a first air inlet, and the top cover 330 is provided with a second air inlet, both of which are directly communicated with the second cavity 302, and the second cavity 302 exchanges gas and heat with the external area of the cabinet body 310 through the first air inlet, and exchanges gas and heat with the external area of the top cover 330 through the second air inlet.

[0179] The arrangement of the first air inlet and the second air inlet can realize the ventilation and heat dissipation of the second cavity 302, and through the operation of the fan, the flow of gas between the second cavity 302 and the external environment can be accelerated, the temperature in the second cavity 302 can be reduced, and the normal operation of the internal equipment can be maintained, and the first air inlet and the second air inlet form an air duct when the fan operates, and the inlet and outlet of the air duct can be exchanged to provide multiple gas flow modes.

[0180] It can be understood that by adopting the above structure, the first air port is arranged on the box body 310, and the second air port is arranged on the top cover 330. The two air ports arranged in a dispersed manner help to form convection, thereby increasing the heat dissipation area and improving the heat dissipation efficiency. Meanwhile, the second air port on the top cover 330 can serve as an exhaust port to quickly exhaust the heat generated inside the box 30, thereby reducing the risk of overheating of the equipment.

The first air port and the second air port can be openings or channels, and are both in communication with the second cavity 302. The second cavity 302 exchanges gas and heat with the external area of the box body 310 through the first air port and the second air port.

[0184] The positions and sizes of the first air port and the second air port are determined according to the specific structure of the box body 310 and the requirements of the internal equipment. Generally, the first air port and the second air port are designed at positions that can maximize the ventilation effect and do not hinder other functional components. The first air port and the second air port allow gas to flow, but can maintain a certain sealing property when ventilation is not needed, so as to reduce the risk of dust, foreign matter, etc. entering the second cavity 302.

[0185] The arrangement of the first air port and the second air port can realize ventilation and heat dissipation of the second cavity 302. Through the operation of the fan, the flow of gas between the second cavity 302 and the external environment can be accelerated, the temperature in the second cavity 302 can be reduced, and the normal operation of the internal equipment can be maintained. The first air port and the second air port form an air duct when the fan operates. The inlet and outlet of the air duct can be exchanged to provide multiple gas flow modes.

[0186] It can be understood that by adopting the above structure, the first air port and the second air port are both arranged on the box body 310, which can reduce the additional top cover 330 or other structures, thereby increasing the air flow, improving the heat dissipation efficiency, and making the overall design more compact, and simplifying the maintenance and cleaning process.
