[0002] With the rapid development of power electronics technology, distribution control equipment plays an increasingly important role in power systems. However, since distribution control equipment generates a lot of heat during operation, if the heat cannot be dissipated in a timely and effective manner, it will lead to equipment performance degradation and even cause equipment failure.

[0004] In this comparative document, a motor, a first ventilation fan, a second ventilation fan and other components are matched to realize that one motor drives two ventilation fans at the same time, which speeds up the intake of cold air from the outside and also speeds up the outflow of hot air from the equipment cabinet. However, the ventilation fan is easily damaged after working for a long time, and the air replaced needs to be dusted. The operation process is relatively cumbersome, and a large amount of manpower and material resources are required to maintain the equipment.

[0021] The following is combined with Figure 1-4 This application is described in further detail.

[0022] The present application embodiment discloses a heat dissipation device for power distribution control equipment, referring to Figure 1-Figure 4 , including a distribution cabinet 1, one side of the distribution cabinet 1 is movably connected with a cabinet door 2 through a hinge, one side of the distribution cabinet 1 is provided with a controller 4, one side of the distribution cabinet 1 is fixedly connected with a support frame 5, the top of the support frame 5 is fixedly connected with a water tank 11, the water tank 11 is filled with coolant, one side of the water tank 11 is fixedly connected with a fixing plate 16, the top of the support frame 5 is fixedly connected with two water pumps 6, an S-shaped cooling pipe 13 is arranged inside the distribution cabinet 1, a temperature sensor 12 is installed on the inner wall of the distribution cabinet 1, and a temperature threshold value of 45°C can be set in the temperature sensor 12. When the temperature in the distribution cabinet 1 is higher than the set temperature threshold value, the temperature sensor 12 can transmit a signal to the controller 4. The controller 4 receives the signal and immediately turns on the two water pumps 6 to circulate the water in the water tank 11 through the S-shaped cooling pipe 13, so that the distribution cabinet 1 can be continuously and timely cooled. When the temperature sensor 12 senses that the temperature in the distribution cabinet 1 is lower than the set temperature threshold value, it immediately transmits a signal to the controller 4, and the controller 4 immediately stops the operation of the two water pumps 6.

[0023] Reference Figure 2 and Figure 3 The input end of one of the water pumps 6 is connected to an inlet pipe 7, the other end of the inlet pipe 7 passes through the top of the power distribution cabinet 1 and is connected to one end of the S-shaped cooling pipe 13, the output end of the water pump 6 is connected to an outlet pipe 8, the other end of the outlet pipe 8 is connected to the top of the water tank 11, the input end of the other water pump 6 is connected to an inlet pipe 10, the other end of the inlet pipe 10 is connected to the bottom of the fixing plate 16, the output end of the water pump 6 is connected to an outlet pipe 9, the other end of the outlet pipe 9 is connected to the other end of the S-shaped cooling pipe 13, the controller 4 receives the temperature in the power distribution cabinet 1 When the signal is too high, two water pumps 6 are started synchronously. One water pump 6 sucks the coolant in the water tank 11 through the water inlet pipe 10, and pressurizes it into the S-shaped cooling pipe 13 through the water outlet pipe 9. At the same time, the other water pump 6 sucks the coolant in the S-shaped cooling pipe 13 through the water inlet pipe 7, and enters the water tank 11 through the water outlet pipe 8 for cooling. The water in the S-shaped cooling pipe 13 is always circulating and at a low temperature, which can better absorb the heat in the distribution cabinet 1, quickly cool down the inside of the distribution cabinet 1, and recycle the coolant to save resources.

[0024] Reference Figure 3 A heat dissipation groove 17 is provided on one side of the bottom of the distribution cabinet 1. The heat dissipation groove 17 is provided with a plurality of circular holes. Heat dissipation holes 18 are provided on both sides of the heat dissipation groove 17. Baffles 3 are fixedly connected to both sides of the distribution cabinet 1. The heat inside the distribution cabinet 1 can be dissipated into the heat dissipation groove 17 through the plurality of circular holes and dissipated through the heat dissipation grooves 17 on both sides. The baffles 3 can shield the heat dissipation groove 17 from rain. The heat is dissipated from the bottom of the distribution cabinet 1, which can prevent rain and wind from directly entering the inside of the distribution cabinet 1 from the heat dissipation groove 17, causing the electrical components of the distribution cabinet 1 to be damp and short-circuited.

[0025] Reference Figure 2 and Figure 4 A water baffle 14 is fixedly connected to the top of the inner wall of the water tank 11, and the water baffle 14 is inclined. A heat dissipation hole 15 is opened on the top of the fixed plate 16. The coolant after absorbing heat output by the water outlet pipe 8 can fall to the top of the water baffle 14, so that the coolant falls in a waterfall shape, increasing the heat dissipation area of ​​the coolant. The heat dissipation hole 15 is convenient for the heat dissipation, so that the coolant can be cooled quickly and with low energy consumption.

[0026] Reference Figure 1-Figure 4 The water pump 6 and the temperature sensor 12 are both electrically connected to the controller 4. The temperature sensor 12 can transmit a temperature signal to the controller 4, and the controller 4 immediately controls the start and stop of the two water pumps 6 according to the received signal.

[0027] The implementation principle of a heat dissipation device for power distribution control equipment in an embodiment of the present application is as follows: by setting two controllers 4, an S-shaped cooling tube 13 and a temperature sensor 12, the heat inside the power distribution cabinet 1 can be dissipated into the heat dissipation slot 17 through a plurality of circular holes, and dissipated through the heat dissipation slots 17 on both sides. The baffle 3 can protect the heat dissipation slots 17 from rain, and the heat is dissipated from the bottom of the power distribution cabinet 1, which can prevent rain and wind from directly entering the power distribution cabinet 1 from the heat dissipation slots 17 and causing the electrical components of the power distribution cabinet 1 to be damp and short-circuited. The temperature threshold can be set to 45°C in the temperature sensor 12. When the temperature inside the power distribution cabinet 1 is higher than the set temperature threshold, the temperature sensor 12 can transmit a signal to the controller 4. The controller 4 receives a signal that the temperature inside the power distribution cabinet 1 is too high, and synchronously starts two water pumps 6, one water pump 6 sucks the coolant in the water tank 11 through the water inlet pipe 10, and pressurizes it into the S-shaped cooling pipe 13 through the water outlet pipe 9. At the same time, another water pump 6 sucks the coolant in the S-shaped cooling pipe 13 through the water inlet pipe 7, and enters the water tank 11 through the water outlet pipe 8. The coolant output by the water outlet pipe 8 after absorbing heat can fall to the top of the water baffle 14, so that the coolant falls in a waterfall shape, increasing the heat dissipation area of ​​the coolant. The heat dissipation hole 15 is convenient for heat dissipation, so that the coolant can be cooled quickly and with low energy consumption, so that the water in the S-shaped cooling pipe 13 is always circulating and at low temperature, which can better absorb the heat in the distribution cabinet 1, quickly cool the inside of the distribution cabinet 1, and can recycle the coolant, save resources, and has the effect of high-efficiency and low-energy cooling.
