[0002] The distribution cabinet is responsible for the distribution and control of electric energy in the power system. The internal electrical components continuously generate heat during operation. If the heat accumulation causes the temperature inside the cabinet to be too high, it will accelerate component aging, reduce insulation performance, and even cause failures. Traditional heat dissipation methods often use simple ventilation holes or ordinary fans, which have problems such as low heat dissipation efficiency and unreasonable airflow organization, making it difficult to accurately control the temperature.

[0018] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the present invention.

[0019] Reference Figure 1-Figure 4 As shown, the present invention provides a technical solution: a power distribution cabinet with adaptive temperature regulation, comprising a power distribution cabinet housing 1, a power distribution chamber 11 and a heat dissipation chamber 12 are provided inside the power distribution cabinet housing 1, the power distribution chamber 11 is arranged above the heat dissipation chamber 12, a first heat dissipation groove 13 and a second heat dissipation groove 14 are provided on the surface of the partition between the power distribution chamber 11 and the heat dissipation chamber 12, a fan 15 is provided inside the heat dissipation chamber 12, a vertical plate 18 is provided on the inner wall of the power distribution chamber 11, a cooling groove 17 is provided inside the power distribution cabinet housing 1, a partition component 2 is provided inside the cooling groove 17, an exhaust component 3 is provided on one side of the power distribution cabinet housing 1, and a temperature sensor 5 is provided on the inner wall of the power distribution chamber 11; The partition component 2 includes a first long rod 21 rotatably connected to the inner wall of the distribution cabinet shell 1, a windshield 22 is fixedly connected to the outside of the first long rod 21, a second long rod 23 is also fixedly connected to the inner wall of the distribution cabinet shell 1, a flip plate 24 is fixedly connected to the outside of the second long rod 23, one side of the windshield 22 is fitted with one side of the flip plate 24, and a guide plate 26 is fixedly connected to the side of the flip plate 24 close to the windshield 22. During the operation of the distribution cabinet, the temperature sensor 5 is used to monitor the internal temperature of the distribution cavity 11, and the fan 15 is controlled to switch according to the monitored temperature. The flow rate difference generated by the blowing of the fan 15 is used to blow the hot air inside the distribution cavity 11 through the first heat dissipation slot 13 and the second heat dissipation slot 14. The two heat dissipation slots 14 are discharged into the interior of the distribution cavity 11, and the hot air is discharged to the exhaust component 3 by the power of the blowing air, thereby discharging the hot air. When the temperature is too high, the working power of the fan 15 is increased, and a stronger blowing airflow is used to enhance the extraction effect from the first heat dissipation slot 13 and the second heat dissipation slot 14. At the same time, a stronger airflow impacts the surface of the flip plate 24, thereby driving the second long rod 23 and the flip plate 24 to flip. The guiding effect of the guide plate 26 is used to guide part of the airflow to the wind shield 22, thereby pushing the wind shield 22 open. Part of the hot air will rush through the wind shield 22 and enter the cooling slot 17 for subsequent hot air cooling, gas circulation, and auxiliary heat dissipation work such as increasing the exhaust port.

[0020] Reference Figure 1-Figure 7As shown, in this embodiment: the first heat dissipation groove 13 and the second heat dissipation groove 14 are respectively arranged in the blowing direction and the exhaust direction of the fan 15, the upper groove of the first heat dissipation groove 13 is larger than the lower groove, and the first heat dissipation groove 13 and the second heat dissipation groove 14 are respectively arranged on both sides of the fan 15. When the fan 15 is working, the fan 15 can use the negative pressure of the air flow to drive the hot air inside the distribution cavity 11 to be discharged from the first heat dissipation groove 13. The setting of the first heat dissipation groove 13 with a large upper mouth and a small lower mouth can further enhance the negative pressure flow rate. In addition, the second heat dissipation groove 14 corresponds to the exhaust direction of the fan 15. When the fan 15 blows air, the hot air at the rear can be directly discharged from the second heat dissipation groove 14 to the heat dissipation cavity 12, realizing exhaust from both sides. Compared with the traditional single-sided exhaust, the exhaust effect is initially consumed, and the double-sided exhaust has higher exhaust efficiency.

[0021] A torsion spring 25 is provided at the connection between the second long rod 23 and the inner wall of the distribution cabinet housing 1. The torsion spring 25 is provided to reset the second long rod 23 and the flip plate 24 after exhausting.

[0022] A return air groove 16 is provided on the inner wall of the cooling groove 17. The cooling groove 17 is connected to the interior of the distribution chamber 11 through the return air groove 16. A one-way pressure valve is provided inside the return air groove 16. Through the setting of the return air groove 16, when the hot air passes through the cooling groove 17, it returns to the interior of the distribution chamber 11 through the return air groove 16 and the one-way pressure valve, forming an air flow circulation.

[0023] A support plate 181 is fixedly connected to one side of the vertical plate 18, and the support plate 181 is in contact with the bottom surface of the windshield 22. The setting of the support plate 181 supports the windshield 22 from the bottom, thereby preventing the windshield 22 from flipping downward.

[0024] The exhaust component 3 includes an exhaust frame 31 fixedly connected to one side of the distribution cabinet housing 1. The exhaust frame 31 is arranged corresponding to the distribution chamber 11. The inner wall of the exhaust frame 31 is rotatably connected to a rotating rod 32. The outer side of the rotating rod 32 is fixedly connected to an exhaust fan blade 33. The outer side of the rotating rod 32 is fixedly connected to an empty slot 35. A rotating slot is provided on one side of the exhaust frame 31. The empty slot 35 is provided inside the rotating slot. A second adjustment slot 241 is provided on the side of the flip plate 24 close to the exhaust frame 31. A short rod is fixedly connected to the inner wall of the second adjustment slot 241. A movable plate 34 is provided on one side of the exhaust frame 31. A first adjustment slot 37 is provided on the side of the movable plate 34 close to the flip plate 24. A short rod is fixedly connected to the inner wall of the first adjustment slot 37. The outer sides of the two groups of short rods are sleeved with adjustment rods 38 The movable plate 34 is provided with an empty slot 35 on one side close to the exhaust frame 31, and one end of the insertion rod 36 is clamped in the inside of the empty slot 35. When the wind force increases, the exhaust is driven by the blast exhaust to drive the flip plate 24 to flip, so that the short rod is used in conjunction with the adjusting rod 38 to apply a downward squeezing force to the movable plate 34, thereby driving the movable plate 34 to move vertically downward, and the limiting effect of the empty slot 35 cooperates with the insertion rod 36 to drive the rotating rod 32 and the exhaust fan blades 33 to flip. During normal exhaust, the exhaust fan blades 33 are tilted downward to prevent dust from directly entering the distribution cabinet housing 1. At this time, the exhaust fan blades 33 are flipped and kept horizontal with the exhaust direction. Under the action of strong exhaust, dust is not easy to enter the interior of the distribution cabinet housing 1. At the same time, the horizontal setting reduces the obstruction effect on exhaust.

[0025] A filter 311 is provided on the side of the exhaust frame 31 that contacts the outside world. The filter 311 prevents dust from entering the inside of the power distribution cabinet housing 1 from the outside world.

[0026] A liquid cooling component 4 for liquid cooling is provided at the bottom of the distribution cabinet shell 1. The liquid cooling component 4 includes a liquid storage tank 41 arranged inside the distribution cabinet shell 1. The liquid storage tank 41 is arranged below the heat dissipation cavity 12. A liquid pump 42 is fixedly connected to one side of the liquid storage tank 41. The output and input ends of the liquid pump 42 are fixedly connected to a liquid injection pipe 43. The input end liquid injection pipe 43 is connected to the interior of the liquid storage tank 41, and the output end liquid injection pipe 43 is connected to the interior of the vertical plate 18. A return liquid port 44 is provided on the upper surface of the liquid storage tank 41. The interior of the liquid storage tank 41 is filled with coolant. The coolant inside the liquid storage tank 41 is drawn out from the liquid injection pipe 43 through the liquid pump 42 and the liquid injection pipe 43, and is poured into the vertical plate 18 and the interior of the distribution cabinet shell 1 through the liquid injection pipe 43, and finally flows back from the return liquid port 44 to form a cooling liquid circulation.

[0027] The vertical plate 18 is a hollow structure, and the inner walls on both sides of the distribution chamber 11 are hollow structures. The vertical plate 18 is connected to the hollow structures of the inner walls on both sides of the distribution chamber 11, and the hollow structure corresponding to the distribution chamber 11 is arranged corresponding to the liquid return port 44. The cooling liquid is injected into the vertical plate 18, and the vertical plate 18 is continuously filled from the bottom to rise to the top of the hollow structure of the distribution chamber 11. The cooling liquid flows downward from the distribution chamber 11 and finally flows back to the liquid storage tank 41. The hot air entering the cooling tank 17 can be cooled in the process of moving in contact with the vertical plate 18, and returns to the distribution chamber 11 from the return air tank 16 above, providing power for the downward movement of the airflow while cooling the hot air concentrated above.

[0028] The temperature sensor 5 is connected to the fan 15 and the liquid pump 42 by signals. During actual operation, the temperature sensor 5 is used to monitor the temperature in real time, thereby adjusting the power of the fan 15 and the liquid pump 42.

[0029] Working Principle: The temperature of the distribution chamber 11 is monitored in real time by the temperature sensor 5. When the temperature rises, the control system triggers the fan 15 to start. The flow rate difference generated by the air blowing forms a double-sided convection through the first and second heat dissipation slots 13 and 14, drawing the hot air into the heat dissipation chamber 12 and discharging it through the exhaust component 3. As the temperature continues to rise, the fan power increases, and the airflow impacts the flip plate 24, causing it to flip. The guide plate 26 pushes open the wind shield 22, opening the cooling slot 17 channel to divert the hot air. At the same time, the flip plate and the movable plate 34 rotate the exhaust fan blades 33 to a horizontal position to reduce exhaust resistance. Part of the cooling air returns to the distribution chamber through the one-way pressure valve of the return gas slot 16, forming a cycle. When the temperature rises further, the liquid pump 42 is activated, and the coolant enters the vertical plate 18 and the hollow structure on both sides of the distribution chamber through the liquid injection pipe 43. After absorbing heat, it returns through the return liquid port 44, forming a three-dimensional heat exchange network in conjunction with the air cooling. After the temperature drops, the components reset under the action of the torsion spring 25 and gravity, resuming the basic cooling mode and achieving multi-level adaptive temperature control.

[0030] The technical scope of the present invention is not limited to the contents of the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
