Description

Technical Field

[0002] The electric control cabinet is a control cabinet that assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to the requirements of electrical wiring. Its layout should meet the requirements of normal operation of the power system, be easy to repair, and not endanger the safety of people and surrounding equipment. During normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches. When the electrical equipment installed inside the electric control cabinet works normally, a certain temperature will be generated. In order to protect the electrical equipment inside the electric control cabinet, the electric control cabinet needs to be cooled in time. Therefore, there are certain requirements for the heat dissipation function of the electric control cabinet.

[0003] After searching, the electric control cabinet with patent publication number "CN107750115B" has a heat dissipation pipe arranged in the housing of the electric control cabinet, and the heat dissipation pipe is directly connected to the inverter and the air outlet, so that the heat dissipated by the inverter is directly discharged through the heat dissipation pipe, the heat dissipation fan and the air outlet. The heat dissipation of the inverter is more direct and the heat dissipation efficiency is higher. The inverter can be cooled more effectively to ensure the safe operation of the inverter. The heat dissipation channel is used to directly transfer the hot air discharged by the inverter to the outside of the housing of the electric control cabinet, and there is no need to install a heat dissipation fan in the housing of the electric control cabinet, which reduces costs and space occupation.

[0004] The above technical features have the following deficiencies: when dissipating heat inside the electric control cabinet, hot air is only discharged from the inside of the electric control cabinet with the help of simple heat pipes and heat dissipation fans. The air fluidity is not strong and the heat dissipation effect is poor. During long-term use, heat will still gradually accumulate inside the electric control cabinet, which will have a certain impact on the normal operation of the electrical equipment inside the electric control cabinet.

[0016] In summary, the beneficial effects of this solution are: 1.

Since the first guide plate is an inclined upward structure, it can facilitate the air to drop and be directly guided to the inside of the main box. In rainy and snowy weather, rainwater can directly enter the bottom of the main box along the first guide plate, thereby continuously providing a cooling effect on the inside of the main box. When the hot air passes through the second guide plate with an inclined downward structure, it will have a path of moving obliquely downward, thereby pushing the air outside the main box downward, so that the gas with lower temperature outside the main box can more easily drop and enter the main box through the air intake groove. Through the exhaust mechanism, the hot air inside the main box can have stronger kinetic energy, thereby pushing and guiding the air outside the main box more quickly.

[0017] 2. Through the heat dissipation rod, when the air or rainwater outside the main box enters the main box through the air inlet groove, since the first heat conduction plate, the second heat conduction plate and the heat dissipation rod made of copper have good thermal conductivity, the temperature inside the main box can be transferred to the second heat conduction plate more quickly through the heat dissipation rod, and heat is exchanged with the air at the bottom of the main box, thereby further improving the heat dissipation effect of the electrical components inside the main box.

[0018] 3. Through the setting of the rotating shaft, when the driving motor starts and drives the rotating shaft to rotate, since multiple stirring plates will rotate at the same time, the wind force generated will hit and diffuse the gradually rising hot air to both ends of the main box, so that the originally gradually dissipated hot air will flow out faster, so that the hot air has a certain kinetic energy, which can better push the air outside the main box. When the driving motor drives the rotating shaft to rotate, the inner ring and the fan blades that rotate with the rotating shaft will transport the hot air upward from bottom to top, further improving the discharge effect of the hot air inside the main box. 4. Through the setting of the rotating rod, when the hot air is discharged downward through the exhaust groove, the pushed air has strong kinetic energy. At this time, the hot air impacting the stirring plate will drive one of the pulleys to rotate, and under the action of the rotating belt, drive the other pulley and the rotating rod to rotate. At this time, when the other stirring plates are rotating, the cold air at the bottom of the main box will be squeezed into the inside of the main box more quickly, further improving the air flow effect.

When in use, the electrical equipment can be cooled by the provided mounting mechanism It is fixedly installed, and when the electrical equipment is working inside the main box 1, the hot air generated will be discharged through the exhaust slot 8, and since the air with lower temperature will drop, the outside air can better enter the main box 1 from the air inlet slot 4. Since the first guide plate 3 is an inclined upward structure, it can facilitate the air to drop and be directly guided to the inside of the main box 1, and when encountering rainy and snowy weather, rainwater can directly enter the bottom of the main box 1 along the first guide plate 3, thereby continuously providing a cooling effect on the inside of the main box 1, and when the hot air passes through the second guide plate 9 with an inclined downward structure, it will have a path of moving obliquely downward, thereby pushing the air outside the main box 1 downward, so that the gas with lower temperature outside the main box 1 can more easily drop and enter the main box 1 through the air inlet slot 4. Through the exhaust mechanism set, the hot air inside the main box 1 can have stronger kinetic energy, so that the air outside the main box 1 can be pushed and guided more quickly.

When rainwater outside the main box 1 enters the bottom of the main box 1 through the air inlet groove 4 and the first guide plate 3, it will flow along the guide plate 23 to the middle position of the bottom of the main box 1, so that the rainwater can be evenly distributed on the top of the first heat conducting plate 10, thereby improving the cooling effect on the first heat conducting plate 10, and when rainwater gradually accumulates and overflows the vertical pipe 30, the excess water will be discharged through the vertical pipe 30, the docking hole 31 and the drainage hole 28, thereby achieving a limiting effect on the water level.

Since the first guide plate 3 is an inclined upward structure, it can facilitate the air to drop and be directly guided to the inside of the main box 1. In rainy and snowy weather, rainwater can directly enter the bottom of the main box 1 along the first guide plate 3, thereby continuously providing a cooling effect on the inside of the main box 1. When the hot air passes through the second guide plate 9 with an inclined downward structure, it will have a path of moving obliquely downward, thereby pushing the air outside the main box 1 downward, so that the gas with lower temperature outside the main box 1 can more easily drop and enter the inside of the main box 1 through the air inlet slot 4. When the driving motor 40 is started and drives the rotating shaft 35 to rotate, since the multiple stirring plates 32 will rotate at the same time, the wind force generated will blow and diffuse the gradually rising hot air to both ends of the main box 1, making the originally gradually The dissipated hot air will flow out faster, so that the hot air has a certain kinetic energy, which can better push the air outside the main box 1. When the driving motor 40 drives the rotating shaft 35 to rotate, the inner ring 36 and the fan blades 37 that rotate with the rotating shaft 35 will transport the hot air upward from bottom to top. Through the set flow limiting box 16, when the hot air is transported to the top of the main box 1 by the fan blades 37, with the rotation of the stirring plate 32 and the limiting of the flow limiting box 16, the hot air can be discharged smoothly through the exhaust groove 8, preventing the hot air from accumulating on the top of the main box 1 and causing turbulence, affecting the discharge of hot air. When the air outside the main box 1 enters the bottom of the main box 1 through the air inlet groove 4, since the air will enter the top of the main box 1 through the first through hole 25, the air will accumulate to the middle position of the bottom of the main box 1, and when the air rises, it will be limited and guided by the flow limiting plate 24, so that the air rises as much as possible through the first through hole 25 instead of flowing out of the main box 1 through the air inlet groove 4.
