Description

Technical Field

[0001] The present invention relates to the technical field of control cabinets, and in particular to a thermal power heat storage integrated control cabinet. Background Art

[0002] The thermal power heat storage integrated control cabinet is a control device specially designed for the thermal power heat storage system. It integrates a variety of electrical components and control devices to achieve comprehensive monitoring, adjustment and protection of the thermal power heat storage system. The electrical components in the above control cabinet often generate heat continuously during operation. If this heat cannot be dissipated in time, it will cause the temperature inside the control cabinet to rise. Excessive temperature will reduce the service life of the electrical parts inside the control cabinet and even cause damage. In severe cases, it may also cause a fire. Therefore, heat dissipation inside the control cabinet is very important.

[0003] Most of the existing thermal power heat storage integrated control cabinets dissipate heat inside them through cooling fans or natural heat dissipation. However, these two methods have obvious limitations when applied to large and high-power thermal power heat storage integrated control cabinets. When facing the large amount of heat generated inside the large and high-power control cabinet, the cooling fan's heat dissipation capacity may be difficult to discharge the heat inside the above control cabinet in time, which may easily cause local heat accumulation and poor heat dissipation effect. At the same time, since natural heat dissipation mainly depends on the natural flow of air and the thermal conductivity of the cabinet material, its heat dissipation efficiency is relatively low, and it often cannot meet the heat dissipation requirements of the above control cabinet, that is, it cannot effectively dissipate heat and is not practical.

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] 1. The present invention can build a continuous air flow circulation system inside the control cabinet through the mutual cooperation of the inner cabinet, the mounting plate, the circulation heat dissipation mechanism and the auxiliary air intake mechanism, and utilize the shape setting of the inner cabinet to form a chimney effect. At this time, the hot air inside the inner cabinet can naturally rise and be discharged, while the external cold air is sucked in from the vents and air inlets on the inner cabinet, thereby being able to quickly and conveniently achieve effective heat dissipation of the inner cabinet (inside the control cabinet), and through the setting of the second fin in the air intake assembly, the temperature difference between the external cold air and the hot air inside the inner cabinet can be increased, thereby being able to strengthen the effect of the chimney effect, and further being able to improve the overall heat dissipation effect inside the inner cabinet. In addition, through the inclined setting of the mounting plate and the mutual cooperation of the auxiliary heat dissipation mechanism, the heat dissipation effect on the interior of the front chamber and the interior of the rear chamber can be effectively improved, thereby further improving the heat dissipation effect on the interior of the control cabinet, and further effectively ensuring the service life of the electronic components inside the control cabinet.

[0021] 2. The present invention, through the provision of a hood in the circulation heat dissipation mechanism and the rotation of the hood when discharging hot air, can make the hot air in the front chamber be discharged more smoothly, thereby preventing the accumulation of hot air and preventing foreign matter from entering the front chamber. This helps to maintain the sealing and stability of the front chamber (i.e., the inner cabinet), and through the provision of a connecting pipe, the flow path of the hot air can be extended, thereby enhancing the chimney effect and further improving the heat dissipation effect of the front chamber. In addition, through the inclined setting of the mounting plate, not only the convenience of wire connection in the control cabinet and the maintenance and repair of electronic components can be improved, but also the obstruction of the hot air in the front chamber during the rising process can be reduced, avoiding the formation of a hot zone around the equipment where hot air may be retained, thereby enabling the heat inside the front chamber to be discharged more quickly through the hood, thereby further improving the heat dissipation effect of the front chamber.

[0022] 3. The present invention, through the provision of an auxiliary heat dissipation mechanism, can utilize multiple groups of first fins arranged in an inverted "V" shape to absorb the heat from the back of the mounting plate and the back area (i.e., the rear chamber), and absorb more heat from the high-heat area below the rear chamber through the first fins with a larger area located below, and directly dissipate heat through the second fan under the rear cabinet door (i.e., discharge the hot air in the rear chamber), and at the same time, part of the hot air in the rear chamber that is not discharged by the second fan will be discharged through the air outlet pipe under the action of the first fan, thereby effectively improving the heat dissipation effect on the interior of the rear chamber, in addition, because the air outlet pipe, i.e., the air outlet end, faces the two groups of hoods, the hood that rotates through the chimney effect will accelerate the rotation driven by the hot air discharged from the air outlet pipe, thereby further promoting the discharge of hot air in the front chamber, and further improving the heat dissipation effect of the front chamber.

[0023] 4. The present invention, through the setting of the jet assembly in the auxiliary heat dissipation mechanism, utilizes the high-speed airflow sprayed from the nozzle, which can not only push the hot air located at the bottom of the rear chamber to flow upward, and assist the chimney effect to exchange heat, thereby improving the heat dissipation effect of the rear chamber, but also can directly dissipate the heat of multiple groups of first fins, and first directly dissipate the heat of the first fins with higher temperature at the bottom, thereby effectively ensuring the heat dissipation effect of the rear chamber. In addition, through the through grooves that increase from bottom to top on the multiple groups of first fins, it can adapt to the shape of the high-speed airflow sprayed from the nozzle, that is, it can adapt to the high-speed airflow in the shape of an inverted trapezoid, thereby avoiding the multiple groups of first fins from blocking the high-speed airflow sprayed from the nozzle, thereby ensuring that the high-speed airflow can act normally on the rear chamber.

[0024] 5. The present invention can cooperate with the chimney effect to allow more external cold air to enter the inner cabinet through multiple groups of air inlets through the setting of the auxiliary air intake mechanism, thereby improving the overall heat dissipation effect of the inner cabinet, and through the arc-shaped downward opening setting of the air inlet and the setting of the dustproof net, it can effectively reduce the entry of dust and impurities when the external cold air enters the inner cabinet. In addition, since the air flow speed sprayed by the nozzle is relatively fast, the internal pressure of the inner cabinet will be lower than that of the outside at this time. Under the action of air pressure, more cold air enters the inner cabinet from the air inlet along the inverted "V"-shaped first fin. Since the positions of the multiple groups of air inlets correspond to the positions of part of the first fins, when more cold air enters the inner cabinet through the air inlet, it can not only improve the overall heat dissipation effect of the inner cabinet, but also further take away the heat on part of the first fins, thereby further ensuring the heat dissipation effect of the rear chamber in the inner cabinet.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] Reference Figures 1 to 5 A thermal power heat storage integrated control cabinet comprises an outer cabinet 1, the bottom end of the outer cabinet 1 is through-set, and a base 10 is installed at the bottom end of the outer cabinet 1, a cavity is opened at the top of the base 10, the front end and the rear end of the outer cabinet 1 are opened, and the front opening and the rear opening of the outer cabinet 1 are respectively movably installed with a front cabinet door 2 and a rear cabinet door 11, the size of the rear cabinet door 11 is smaller than the size of the front cabinet door 2, a control panel 3 and a plurality of groups of buttons 4 are fixedly installed on the front cabinet door 2, and two groups of windows 5 are installed on the front cabinet door 2, an inner cabinet 15 is installed on the inner wall of the outer cabinet 1, the inner cabinet 15 is through-set from front to back, and the bottom end of the inner cabinet 15 is through-set, the top width of the inner cabinet 15 is smaller than the bottom width, and the two opposite groups of side walls of the inner cabinet 15 are both convex inwardly, which is used to make the inner cabinet 15 as a whole chimney-shaped, so as to better A chimney effect is formed inside the cabinet 15. A mounting plate 16 is installed on the inner wall of the inner cabinet 15. The mounting plate 16 is tilted in the rearward direction. The interior of the inner cabinet 15 is divided into a front chamber and a rear chamber by the mounting plate 16. A plurality of mounting rails 18 are evenly and detachably installed on the front end of the mounting plate 16. The mounting rails 18 are mainly used for installing electronic components. A plurality of wire grooves 17 are provided at the front end of the mounting plate 16. The plurality of wire grooves 17 and the plurality of mounting rails 18 are all located in the front chamber. The wire grooves 17 are mainly used for placing and arranging connecting wires to facilitate the management and fixation of the wires. At the same time, the provision of the wire grooves 17 can increase the heat dissipation area of ​​the mounting plate 16, which helps the heat dissipation of the mounting plate 16 to a certain extent. A circulation heat dissipation mechanism is commonly provided on the outer cabinet 1, the base 10 and the inner cabinet 15 for dissipating heat inside the inner cabinet 15.

[0035] Open the front cabinet door 2 on the outer cabinet body 1, and install the relevant electronic components on the mounting rail 18. The mounting rail 18 can be detachably installed on the front end of the inclined mounting plate 16. The wire groove 17 on the mounting plate 16 is used to place and organize the connecting wires. After the electronic components are installed, connect the wires of the relevant controllers and sensors to the wiring points of the control panel 3 and the button 4 on the back of the front cabinet door 2, and observe the internal switch through the window 5 when necessary.

[0036] Reference Figures 1 to 7 The circulation heat dissipation mechanism includes an air intake component and a first fan 12. The air intake component is arranged inside the base 10, and is used to cool the external cold air and let it enter the inner cabinet 15. The air intake component includes a vent 22 and multiple groups of second fins 23. The vent 22 is arranged through the front end of the base 10, and a dustproof part is arranged on the vent 22. The dustproof part is a prior art, and its specific structural design is not repeated here. The multiple groups of second fins 23 are fixedly installed in the cavity on the base 10, and the multiple groups of second fins 23 are commonly fixedly installed with a partition 24. The partition 24 is "L"-shaped, and one end of the partition 24 faces the mounting plate 16, and the other end of the partition 24 faces the vent 22. The partition 24 is used to divert the external cold air that passes through the vent 22 and enters the multiple groups of second fins 23, so that a part of the external cold air enters the front chamber, and the remaining part of the external cold air enters the rear chamber. Such a design helps to distribute the air flow more evenly and improve the overall heat dissipation effect. rate, and at the same time, the partition 24 can prevent the hot air inside the front chamber from mixing with the hot air in the rear chamber, thereby avoiding affecting the heat dissipation of the front chamber and the rear chamber, thereby effectively ensuring the stability of heat dissipation, the first fan 12 is fixedly installed at the rear end of the outer cabinet 1, and the first fan 12 is located above the rear cabinet door 11, and the rear chamber is connected to the outside through the first fan 12, and an air outlet pipe 8 is installed at the rear end of the outer cabinet 1, and the air outlet pipe 8 is bent. The first fan 12 is located in the air outlet pipe 8, and the inner cabinet 15 and the top of the outer cabinet 1 are jointly provided with an air outlet component for allowing the hot air inside the front chamber to flow out, and the air outlet component includes two groups of connecting pipes 6, the two groups of connecting pipes 6 are symmetrically installed at the top of the inner cabinet 15, and the two groups of connecting pipes 6 are connected to the inside of the front chamber, the tops of the two groups of connecting pipes 6 pass through the inner top wall of the outer cabinet 1 and extend outward, and the tops of the two groups of connecting pipes 6 are rotatably connected with wind caps 7, and the end of the air outlet pipe 8 away from the first fan 12 faces the two groups of wind caps 7.

[0037] Since the mounting plate 16 is tilted in the rearward direction and most of the wires are plugged into the bottom of the electronic components, when the electronic components are mounted on the mounting rail 18, their bottoms are naturally facing the opening at the front end of the outer cabinet 1, which enables the staff to more easily and accurately plug the relevant wires into the interfaces of the electronic components, and also makes the maintenance and inspection of the electronic components more convenient. At the same time, in the thermal power heat storage integrated control cabinet, the high-current main busbar, high-power fuses or energy storage batteries are usually installed below the control cabinet, resulting in a relatively higher temperature below the control cabinet. The air inside the inner cabinet 15 will produce a density difference due to the principle of thermal expansion and contraction, and this density difference will cause the hot air inside it to move upward. At this time, the tilted mounting plate 16 can reduce the obstruction of the hot air in the front chamber during the rising process, and avoid the hot air from forming a stagnant hot zone around the equipment, so that the heat inside the front chamber can be discharged more quickly through the hood 7, thereby effectively improving the heat dissipation effect inside the front chamber.

[0038] Reference Figures 3 to 6 The rear chamber and the plurality of second fins 23 are provided with auxiliary heat dissipation mechanisms for improving the heat dissipation effect of the rear chamber. The auxiliary heat dissipation mechanisms include a second fan 13 and a plurality of first fins 19. The plurality of first fins 19 are sequentially installed on two sets of side walls in the rear chamber from top to bottom, and the side walls of the plurality of first fins 19 are in contact with the mounting plate 16. The areas of the plurality of first fins 19 increase from top to bottom, and the plurality of first fins 19 are arranged in an inverted "V" shape. The second fan 13 is fixedly installed at the rear end of the outer cabinet 1, and the second fan 13 is located below the rear cabinet door 11. The rear chamber is cooled by the second fan 13. Connected to the outside world, a jet assembly is provided on the multiple groups of second fins 23 for jetting the inside of the rear chamber, so as to dissipate heat to the multiple groups of first fins 19 and push the hot air below the rear chamber to flow upward, the jet assembly includes a fixed block 20, the fixed block 20 is fixedly installed on the top of the multiple groups of second fins 23, and the fixed block 20 is located in the rear chamber, a nozzle 21 is installed on the top of the fixed block 20, through grooves are opened in the middle of the multiple groups of first fins 19, and the through grooves on the multiple groups of first fins 19 increase successively from bottom to top, and the positions of the through grooves on the multiple groups of first fins 19 correspond to the positions of the nozzles 21.

[0039] Since the mounting plate 16 in the control cabinet is generally made of metal, the mounting plate 16 can act as a heat spreader, that is, the heat can be concentrated more in the back area of ​​the mounting plate 16 (that is, the rear chamber). Since the side walls of the multiple groups of first fins 19 are in contact with the back of the mounting plate 16 (that is, in contact with the portion of the mounting plate 16 located in the rear chamber), the back of the mounting plate 16 and the back area (that is, the rear chamber) can be dissipated. The first fins 19 arranged in an inverted "V" shape can increase the heat dissipation area of ​​the fins while also increasing the contact area with the mounting plate 16, thereby effectively accelerating the heat transfer rate and dissipating the heat faster. In addition, since the mounting plate 16 is inclined in the rear direction, the area of ​​the first fins 19 at the bottom can be allowed to be larger (that is, the areas of the multiple groups of first fins 19 can be allowed to increase from top to bottom in sequence), thereby absorbing more heat in the high-heat area below and directly dissipating the heat through the second fan 13 under the rear cabinet door 11, effectively improving the heat dissipation effect inside the rear chamber.

[0040] When the hot air in the inner cabinet 15 moves upward, the hot air in the front chamber will pass through the connecting pipe 6 and be discharged through the hood 7, while the hot air in the rear chamber that is not discharged through the second fan 13 will be discharged through the first fan 12 and the air outlet pipe 8. At the same time, the cold air from the outside will pass through the vent 22 with a dustproof part installed on the base 10, and after passing through the second fins 23 separated by the partition 24, enter the front chamber and the rear chamber respectively, thereby forming a continuous air flow cycle, forming a chimney effect, enhancing the natural ventilation of the control cabinet, accelerating the renewal speed of the air in the cabinet, and the cold air from the outside Part of the heat of the air can be taken away in the process of passing through the second fins 23, thereby making its temperature lower, that is, increasing the temperature difference between the cold air outside and the hot air inside the inner cabinet 15, and the larger temperature difference will enhance the convection movement of the air and strengthen the effect of the chimney effect, thereby improving the overall heat dissipation effect inside the inner cabinet 15. In addition, since the top width of the inner cabinet 15 is smaller than the bottom width, and the two opposite sets of side walls of the inner cabinet 15 are both convex inward, the inner cabinet 15 can be made chimney-shaped as a whole, which is more conducive to the occurrence of the chimney effect and more conducive to the heat dissipation inside the inner cabinet 15.

[0041] Reference Figures 1 to 5An auxiliary air intake mechanism is provided on the outer cabinet 1 and the inner cabinet 15, which is used to allow more external cold air to enter the inner cabinet 15. The auxiliary air intake mechanism includes two groups of grooves and multiple groups of air inlets 14. The two groups of grooves are respectively opened on both sides of the outer cabinet 1, and the two groups of grooves are penetrated by square grooves for the multiple groups of air inlets 14 to pass through. The multiple groups of air inlets 14 are respectively fixedly installed on the two groups of outer side walls of the inner cabinet 15, and the multiple groups of air inlets 14 are respectively located in the two groups of grooves. The positions of the multiple groups of air inlets 14 correspond to the positions of some first fins 19, and the multiple groups of air inlets 14 are all arranged in an arc-shaped downward opening, and dustproof nets 9 are installed at the openings of the two groups of grooves.

[0042] Due to the existence of the chimney effect, the air inlet 14 can help increase the amount of cold air entering the inner cabinet 15. At the same time, since the air inlet 14 is isolated by the dustproof net 9 and the air inlet 14 is an arc-shaped downward opening, it can effectively reduce the entry of dust and impurities, thereby preventing external dust and impurities from affecting the electronic components inside the control cabinet. The nozzle 21 set on the fixed block 20 can spray out an inverted trapezoidal high-speed airflow. Since a through groove corresponding to the position of the nozzle 21 is opened at the middle position of the multiple groups of first fins 19, and the through grooves on the multiple groups of first fins 19 increase from bottom to top (that is, adapted to the inverted trapezoidal high-speed airflow shape), on the one hand, the multiple groups of first fins 19 will not block the high-speed airflow sprayed by the nozzle 21, that is, it can push the hot air located at the bottom in the rear chamber to flow upward, assist the chimney effect in heat exchange, and improve the heat dissipation effect. On the other hand, the air sprayed by the nozzle 21 The high-speed airflow can not only directly dissipate the heat for the multiple groups of first fins 19, but also directly dissipate the heat for the first fins 19 with higher temperature at the bottom first, thereby effectively ensuring the accuracy of heat dissipation, and further effectively ensuring the heat dissipation effect of the rear chamber in the inner cabinet 15. In addition, since the airflow velocity ejected by the nozzle 21 is relatively fast, according to Bernoulli's theorem, the greater the air flow velocity, the smaller the pressure (that is, at this time, the pressure inside the inner cabinet 15 is less than that outside), under the action of air pressure, more cold air enters the inner cabinet 15 from the air inlet 14 along the inverted "V"-shaped first fins 19, and since the positions of the multiple groups of air inlets 14 correspond to the positions of some of the first fins 19, when more cold air enters the inner cabinet 15 through the air inlet 14, it can not only improve the overall heat dissipation effect of the inner cabinet 15, but also further take away the heat on some of the first fins 19, thereby further ensuring the heat dissipation effect of the rear chamber in the inner cabinet 15.

[0043] When the hot air reaches the top of the inner cabinet 15, the hot air in the front chamber will pass through the connecting pipe 6 and be discharged through the hood 7. Then the hood 7 will rotate under the action of the hot air. The rotation of the hood 7 itself can make the hot air in the connecting pipe 6 be discharged more smoothly, thereby preventing the accumulation of hot air. At the same time, it can also prevent foreign matter from entering the connecting pipe 6 (that is, preventing it from entering the front chamber), which helps to maintain the sealing and stability of the front chamber (that is, the inner cabinet 15). The connecting pipe 6 can extend the flow path of the hot air, thereby enhancing The chimney effect can improve the heat dissipation effect, and the hot air in the rear chamber that is not discharged through the second fan 13 will be discharged through the air outlet pipe 8 under the action of the first fan 12. The curved setting of the air outlet pipe 8 can avoid the influence of dust or other objects falling into it. At the same time, since the end of the air outlet pipe 8 away from the first fan 12 (i.e., the air outlet end) is facing the two sets of wind hoods 7, the rotating wind hoods 7 generated by the chimney effect will be accelerated by the hot air discharged from the air outlet pipe 8, thereby further promoting the discharge of hot air in the front chamber, thereby improving the heat dissipation effect of the front chamber.

[0044] In the present invention, the front cabinet door 2 on the outer cabinet body 1 is opened, and the relevant electronic components are installed on the mounting rail 18. The mounting rail 18 can be detachably mounted on the front end of the inclined mounting plate 16. The wire groove 17 on the mounting plate 16 is used to place and organize the connecting wires. After the electronic components are installed, the wires of the relevant controllers and sensors are connected to the wiring points of the control panel 3 and the button 4 on the back of the front cabinet door 2, and the internal switch circuit breaker can be observed through the window 5 when necessary.

[0045] Since the mounting plate 16 is tilted in the rearward direction and most of the wires are plugged into the bottom of the electronic components, when the electronic components are mounted on the mounting rail 18, their bottoms are naturally facing the opening at the front end of the outer cabinet 1, which enables the staff to more easily and accurately plug the relevant wires into the interfaces of the electronic components, and also makes the maintenance and inspection of the electronic components more convenient. At the same time, in the thermal power heat storage integrated control cabinet, the high-current main busbar, high-power fuses or energy storage batteries are usually installed below the control cabinet, resulting in a relatively higher temperature below the control cabinet. The air inside the inner cabinet 15 will produce a density difference due to the principle of thermal expansion and contraction, and this density difference will cause the hot air inside it to move upward. At this time, the tilted mounting plate 16 can reduce the obstruction of the hot air in the front chamber during the rising process, and avoid the hot air from forming a stagnant hot zone around the equipment, so that the heat inside the front chamber can be discharged more quickly through the hood 7, thereby effectively improving the heat dissipation effect inside the front chamber.

[0046] Since the mounting plate 16 in the control cabinet is generally made of metal, the mounting plate 16 can act as a heat spreader, that is, the heat can be concentrated more in the back area of ​​the mounting plate 16 (that is, the rear chamber). Since the side walls of the multiple groups of first fins 19 are in contact with the back of the mounting plate 16 (that is, in contact with the portion of the mounting plate 16 located in the rear chamber), the back of the mounting plate 16 and the back area (that is, the rear chamber) can be dissipated. The first fins 19 arranged in an inverted "V" shape can increase the heat dissipation area of ​​the fins while also increasing the contact area with the mounting plate 16, thereby effectively accelerating the heat transfer rate and dissipating the heat faster. In addition, since the mounting plate 16 is inclined in the rear direction, the area of ​​the first fins 19 at the bottom can be allowed to be larger (that is, the areas of the multiple groups of first fins 19 can be allowed to increase from top to bottom in sequence), thereby absorbing more heat in the high-heat area below and directly dissipating the heat through the second fan 13 under the rear cabinet door 11, effectively improving the heat dissipation effect inside the rear chamber.

[0047] When the hot air in the inner cabinet 15 moves upward, the hot air in the front chamber will pass through the connecting pipe 6 and be discharged through the hood 7, while the hot air in the rear chamber that is not discharged through the second fan 13 will be discharged through the first fan 12 and the air outlet pipe 8. At the same time, the cold air from the outside will pass through the vent 22 with a dustproof part installed on the base 10, and after passing through the second fins 23 separated by the partition 24, enter the front chamber and the rear chamber respectively, thereby forming a continuous air flow cycle, forming a chimney effect, enhancing the natural ventilation of the control cabinet, accelerating the renewal speed of the air in the cabinet, and the cold air from the outside Part of the heat of the air can be taken away in the process of passing through the second fins 23, thereby making its temperature lower, that is, increasing the temperature difference between the cold air outside and the hot air inside the inner cabinet 15, and the larger temperature difference will enhance the convection movement of the air and strengthen the effect of the chimney effect, thereby improving the overall heat dissipation effect inside the inner cabinet 15. In addition, since the top width of the inner cabinet 15 is smaller than the bottom width, and the two opposite sets of side walls of the inner cabinet 15 are both convex inward, the inner cabinet 15 can be made chimney-shaped as a whole, which is more conducive to the occurrence of the chimney effect and more conducive to the heat dissipation inside the inner cabinet 15.

[0048] Due to the existence of the chimney effect, the air inlet 14 can help increase the amount of cold air entering the inner cabinet 15. At the same time, since the air inlet 14 is isolated by the dustproof net 9 and the air inlet 14 is an arc-shaped downward opening, it can effectively reduce the entry of dust and impurities, thereby preventing external dust and impurities from affecting the electronic components inside the control cabinet. The nozzle 21 set on the fixed block 20 can spray out an inverted trapezoidal high-speed airflow. Since a through groove corresponding to the position of the nozzle 21 is opened at the middle position of the multiple groups of first fins 19, and the through grooves on the multiple groups of first fins 19 increase from bottom to top (that is, adapted to the inverted trapezoidal high-speed airflow shape), on the one hand, the multiple groups of first fins 19 will not block the high-speed airflow sprayed by the nozzle 21, that is, it can push the hot air located at the bottom in the rear chamber to flow upward, assist the chimney effect in heat exchange, and improve the heat dissipation effect. On the other hand, the air sprayed by the nozzle 21 The high-speed airflow can not only directly dissipate the heat for the multiple groups of first fins 19, but also directly dissipate the heat for the first fins 19 with higher temperature at the bottom first, thereby effectively ensuring the accuracy of heat dissipation, thereby effectively ensuring the heat dissipation effect of the rear chamber in the inner cabinet 15. In addition, since the airflow velocity ejected by the nozzle 21 is relatively fast, according to Bernoulli's theorem, the greater the air flow velocity, the smaller the pressure (that is, at this time, the pressure inside the inner cabinet 15 is less than that outside), under the action of air pressure, more cold air enters the inner cabinet 15 from the air inlet 14 along the inverted "V"-shaped first fins 19, and since the positions of the multiple groups of air inlets 14 correspond to the positions of some of the first fins 19, when more cold air enters the inner cabinet 15 through the air inlet 14, it can not only improve the overall heat dissipation effect of the inner cabinet 15, but also further take away the heat on some of the first fins 19, thereby further ensuring the heat dissipation effect of the rear chamber in the inner cabinet 15.

[0049] When the hot air reaches the top of the inner cabinet 15, the hot air in the front chamber will pass through the connecting pipe 6 and be discharged through the hood 7. Then the hood 7 will rotate under the action of the hot air, and the rotation of the hood 7 itself can make the hot air in the connecting pipe 6 be discharged more smoothly, thereby preventing the accumulation of hot air. At the same time, it can also prevent foreign matter from entering the connecting pipe 6 (that is, preventing it from entering the front chamber), which helps to maintain the sealing and stability of the front chamber (that is, the inner cabinet 15). The connecting pipe 6 can extend the flow path of the hot air, thereby enhancing the effect of the chimney effect, and thus improving the heat dissipation effect. The hot air in the rear chamber that is not discharged by the second fan 13 will be discharged through the air outlet pipe 8 under the action of the first fan 12. The curved setting of the air outlet pipe 8 can avoid the influence of dust or other objects falling into it. At the same time, because the end away from the first fan 12 faces the two groups of hoods 7, the hood 7 that rotates through the chimney effect will accelerate the rotation driven by the hot air discharged from the air outlet pipe 8, thereby further promoting the discharge of hot air in the front chamber, thereby improving the heat dissipation effect of the front chamber.
