[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0017] Please refer to Figures 1-7 , as shown in the figure, an intelligent heat dissipation power cabinet provided in this embodiment is referred to Figures 1-2 as shown, which includes a power cabinet main body 1, and ventilation windows 2 are provided on both sides of the power cabinet main body 1; a gas circulation mechanism 3 is fixedly installed on the top of the power cabinet main body 1.

[0018] Referring to Figures 4-5 and Figure 7 as shown, the gas circulation mechanism 3 includes an air duct limit frame 31 fixedly installed on the top of the power cabinet main body 1. The inside of the air duct limit frame 31 is hollow. The air duct limit frame 31 is arranged above the heat dissipation and waterproof housing inside the power cabinet main body 1. Electronic components can be installed inside the heat dissipation and waterproof housing. The heat dissipation and waterproof housing can also be provided with a plurality of heat dissipation grooves to increase the heat dissipation surface area and ensure that air can pass through the heat generating area on the heat dissipation and waterproof housing. A horizontally arranged limit support plate 32 is fixedly installed inside the air duct limit frame 31. Two through-shaped guide limit grooves 33 are opened inside the limit support plate 32. Limit balance sliders 34 are slidably installed inside the two guide limit grooves 33. Two hollow connection covers 35 are fixedly installed at the bottoms of the two limit balance sliders 34. A heat dissipation fan 36 is rotatably installed inside the cavities of the two hollow connection covers 35; during use, by starting the heat dissipation fan 36 to rotate forward, ventilation is carried out on the top of the power cabinet main body 1, and the wind flows into the inner cavity of the power cabinet main body 1 through the guide limit grooves 33, and takes away the heat of the heat generating area when passing through the heat dissipation and waterproof housing.

[0019] Furthermore, a first connection rod 37 rotatably connected to the hollow connection cover 35 is fixedly connected to the top of the heat dissipation fan 36. A first transmission gear 38 is fixedly installed on the outer wall of the first connection rod 37. The outer walls of the two first transmission gears 38 provided at the bottom of each limit balance slider 34 are engaged with a first transmission belt 39. Among them, one end of a first connection rod 37 is fixedly connected to a motor for driving its rotation, and the other first connection rod 37 rotates synchronously with it through the setting of the first transmission gear 38 and the first transmission belt 39, increasing the number of heat dissipation fans 36 inside the power cabinet main body 1, and then increasing the ventilation points while not requiring additional motors of the same number, reducing energy consumption.

[0020] Furthermore, every two hollow connecting covers 35 are symmetrically arranged with respect to the vertical center line of the limit balance sliding plate 34.

[0021] It should be noted that although the above technical solution can take away a part of the heat of the heat dissipation and waterproof housing through the air flow, when the air temperature is relatively high, the heat that the air flow can take away is relatively limited. Therefore, the above solution can be further designed as follows:

[0022] Furthermore, referring to Figure 3 and Figure 5 As shown, a condensation heat dissipation mechanism 4 is provided at the bottom of the gas flow mechanism 3. The condensation heat dissipation mechanism 4 includes a plurality of ventilation slots 41 opened at the bottom of the air duct limit frame 31. Condensation plates 42 are provided in the inner cavities of the plurality of ventilation slots 41. Heat conduction connecting rods 43 rotatably connected to the air duct limit frame 31 are fixedly installed on both sides of the condensation plate 42. In the normal state, the plurality of condensation plates 42 are vertically arranged inside the ventilation slots 41. First condensation holes 410 penetrating through are opened inside the plurality of condensation plates 42. A plurality of second condensation grooves 411 are opened on both sides of the condensation plate 42.

[0023] Among them, referring to Figure 3 and Figure 6 As shown, one end of the heat conduction connecting rods 43 provided on the opposite sides of every two condensation plates 42 is fixedly connected to a second link slider 46. A positioning support frame 44 is fixedly installed on the inner wall of the main body 1 of the power cabinet. A second guiding slide frame 45 slidably connected to the second link slider 46 is rotatably installed on the outer wall of the positioning support frame 44. A third link slider 47 slidably connected to the second guiding slide frame 45 is rotatably installed on one side of the positioning support frame 44; during actual use, when the third link slider 47 is deflected, it can drive the second guiding slide frame 45 to deflect inside the second guiding slide frame 45, and then synchronously make the second link slider 46 deflect synchronously along the deflected second guiding slide frame 45 inside it, so that the heat conduction connecting rod 43 can drive the condensation plate 42 to perform reciprocating deflection adjustment.

[0024] Preferably, second transmission gears 48 are fixedly installed on the outer walls of the two third link sliders 47 arranged on the same side of the air duct limit frame 31. A second transmission belt 49 is also meshed with the outer walls of the two second transmission gears 48. At the same time, one end of a third link slider 47 arranged on both sides of the air duct limit frame 31 is fixedly connected to a stepping motor for driving its rotation.

[0025] Preferably, a semiconductor refrigerating sheet can also be embedded in the middle position of the condensation plate 42, with the cold surface facing the lower end of the condensation plate 42 and the hot surface facing the radiator fan 36. When the semiconductor refrigerating sheet is working, the temperature of the part of the condensation plate 42 below the semiconductor refrigerating sheet drops, and the temperature of the part of the condensation plate 42 above the semiconductor refrigerating sheet rises. While guiding a large amount of air towards the condensation plate 42, the radiator fan 36 can also dissipate heat from the condensation plate 42 efficiently.

[0026] It can be understood that when the temperature of the heat dissipation and waterproof housing rises, first, the forward rotation of the radiator fan 36 can be controlled, and the wind flows through the guiding and limiting groove 33 into the inner cavity of the power cabinet body 1, taking away the heat of its heating area when passing through the heat dissipation and waterproof housing; when the air temperature is relatively high and the radiator fan 36 cannot meet the heat dissipation requirement of the heat dissipation and waterproof housing, first, the reverse rotation of the radiator fan 36 can be controlled to change the path of the wind, so that the air flows from the heat dissipation and waterproof housing towards the direction where the condensation plate 42 is located; meanwhile, the semiconductor refrigerating sheet is used to cool the condensation plate 42, so that the temperature of the end of the condensation plate 42 close to the heat dissipation and waterproof housing begins to drop. When the temperature drops to the dew point temperature of the water vapor in the air, the water vapor in the air flowing through here begins to condense into water droplets in the first condensation holes 410 and the second condensation grooves 411 of the condensation plate 42; at the same time, the stepping motor can be started to make the third connecting rod slider 47 deflect, and then drive the condensation plate 42 to perform reciprocating deflection and tilting motion. During this motion process, the water droplets condensed in the first condensation holes 410 and the second condensation grooves 411 will be shaken off. Compared with the water droplets that naturally condense and fall, when the shaken-off water droplets fall on the outer wall of the heat dissipation and waterproof housing, not only are the water droplets finer, but also the scattered area is larger and more uniform. Furthermore, these fine water droplets can quickly evaporate and take away the heat of the heat dissipation and waterproof housing, and the interval between the water droplet drops is shorter. Since the water droplets condensed on the cold surface will form an insulating layer if they stay, which will hinder further condensation, a faster shaking-off interval can also greatly improve the condensation efficiency; it can avoid the situation where it is necessary to wait for a long time for the water droplets to slowly condense and become larger before they can overcome gravity and naturally drip. Natural dripping not only has a very limited range, but also the evaporation and heat dissipation efficiency is far lower than that of fine water droplets, and it will form an insulating layer to hinder further condensation.

[0027] In addition, the alternating operation of the forward rotation mode and the reverse rotation mode of the radiator fan 36 can also be controlled. When the radiator fan 36 is in the reverse rotation mode, a large amount of air is guided to flow through the condensation plate 42, so that the condensation plate 42 condenses water droplets and evenly shakes them onto the outer wall of the heat dissipation and waterproof housing. At this time, switch to the forward rotation mode of the radiator fan 36, and the radiator fan 36 guides and blows a large amount of air towards the heat dissipation and waterproof housing with fine water droplets dripping on it, further accelerating the evaporation of the fine water droplets. Repeating this process can greatly improve the heat dissipation efficiency.

[0028] Optionally, a semiconductor refrigeration sheet can be provided at one end of the heat-conducting connecting rod 43 where the second connecting rod slider 46 is not provided, and the cold surface of the semiconductor refrigeration sheet is attached to the outer wall of the heat-conducting connecting rod 43, so that the semiconductor refrigeration sheet can reduce the overall temperature of the condensation plate 42 through the heat-conducting connecting rod 43 during operation.

[0029] It should be noted that when the cooling fan 36 is fixedly arranged, not only is its blowing range limited, but also the long-term concentrated high-speed air flow will cause the contact time between the humid and hot air and the cold surface to be too short, and the water vapor will leave the condensation area without being fully cooled, affecting the efficiency of water droplet condensation. Therefore, the above solution can be further designed as follows:

[0030] Further preferably, the number of the guiding and limiting grooves 33 and the limiting and balancing sliding plates 34 is two each. A sliding component for driving the limiting and balancing sliding plates 34 to slide translationally in the guiding and limiting grooves 33 is provided at the tops of the two limiting and balancing sliding plates 34, and the sliding directions of the two limiting and balancing sliding plates 34 are arranged in opposite states.

[0031] Specifically, the two limiting and balancing sliding plates 34 are arranged in a parallel state with each other. A sliding component for driving the two limiting and balancing sliding plates 34 to slide translationally is provided at the tops of the two limiting and balancing sliding plates 34, and the sliding directions of the two limiting and balancing sliding plates 34 are arranged in opposite states. During actual use, when the sliding component is started to make the two limiting and balancing sliding plates 34 perform synchronous reverse displacement inside the air duct limiting frame 31, the blowing positions of the cooling fans 36 provided at the bottoms of the two limiting and balancing sliding plates 34 can be changed.

[0032] Further preferably, the sliding component includes a first guiding sliding frame 310 fixedly installed at the top of the limiting and balancing sliding plate 34. An electric rotating rod 311 is installed at the top of the main body 1 of the power cabinet. A first connecting rod slider 312 slidably connected to the first guiding sliding frame 310 is fixedly installed at the bottom of the electric rotating rod 311. A sawtooth rack 313 is fixedly installed on one side of the limiting and balancing sliding plate 34. A guiding gear changing ring 314 meshing with the sawtooth rack 313 is installed at the top of the limiting support plate 32.

[0033] Specifically, referring to Figure 7As shown in the figure, the sliding assembly includes a first guiding carriage 310 fixedly installed on the top of the limiting balance slide plate 34. At the top of the main body 1 of the power cabinet, an electric rotating rod 311 extending into the air duct limiting frame 31 is rotatably installed. At the bottom of the electric rotating rod 311, a first connecting rod slider 312 slidably connected to the first guiding carriage 310 is fixedly installed. During actual use, when the electric rotating rod 311 is driven to rotate, the first connecting rod slider 312 slides in the inner cavity of the first guiding carriage 310. With the rotational displacement of the first connecting rod slider 312, it can move to different positions inside the first guiding carriage 310, thereby enabling the first guiding carriage 310 to synchronously drive the limiting balance slide plate 34 fixedly connected thereto to translate on the limiting support plate 32 and the guiding limiting groove 33. At the same time, sawtooth racks 313 are fixedly installed on one side of the two limiting balance slide plates 34. At the top of the limiting support plate 32, a guiding gear change ring 314 meshing with the sawtooth rack 313 is rotatably installed. When the first guiding carriage 310 drives the corresponding limiting balance slide plate 34 to displace, the sawtooth rack 313 provided on one side of this limiting balance slide plate 34 displaces on one side of the guiding gear change ring 314, thereby causing the guiding gear change ring 314 to rotate to drive the other limiting balance slide plate 34 to translate, and the synchronous reverse displacement movement of the two limiting balance slide plates 34 can be realized.

[0034] It can be understood that when the cooling fan 36 is in the forward rotation mode, the two parallel and reversely displaced limiting balance slide plates 34 drive the internal cooling fan 36 to move, forming a uniform air flow, thereby ensuring the smooth flow of air inside the device and uniform heat dissipation. When the cooling fan 36 is in the reverse rotation mode, the two parallel and reversely displaced limiting balance slide plates 34 drive the internal cooling fan 36 to move. When the cooling fan 36 displaces above a first condensation hole 410 and a second condensation groove 411 on the condensation plate 42, the cooling fan 36 simultaneously guides a large amount of new air to the periphery of the first condensation hole 410 and the second condensation groove 411, laying a foundation for efficient condensation. When the cooling fan 36 displaces away from this position, the air flow around the first condensation hole 410 and the second condensation groove 411 is relatively stable, enabling the water vapor in the air to fully contact the surfaces of the first condensation hole 410 and the second condensation groove 411, further improving the condensation efficiency.

[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
