Description

Technical Field

[0001] The present application relates to the technical field of power distribution boxes, and in particular to an energy-saving power distribution box with good heat dissipation effect. Background Art

It is used to control the flow of current and protect electrical equipment from problems such as overload or short circuit. It is usually installed in buildings or facilities. A working chamber is set in the distribution box, and a series of electrical components are installed in the working chamber. When the distribution box is working, heat is generated when the current passes through the electrical components. In order to keep the electrical components within a suitable operating temperature range and reduce the performance degradation or damage of the electrical components due to excessive temperature, the distribution box needs to be able to dissipate heat.

[0003] Referring to the Chinese patent document with the authorization announcement number CN215934234U, the subject name is a distribution box for easy heat dissipation. In the patent, a through slot is provided on the distribution box, which can connect the inside of the distribution box with the outside world. A rotating rod is rotatably connected in the through slot, and blades are fixedly connected to the circumferential side wall of the rotating rod. A slide slot is provided on the distribution box, and a slider is slidably connected in the slide slot. A fan is installed on the slider, and a moving mechanism is provided in the distribution box, which can drive the fan to move back and forth along the slide slot.

[0004] Regarding the above-mentioned related technologies, in areas with a large temperature difference between day and night, the outdoor ambient temperature is high during the day, the temperature difference between the inside and outside of the distribution box is small, or even the outside temperature is higher than the temperature inside the distribution box. At this time, the air inside the distribution box is heat exchanged with the outside air. The temperature inside the distribution box is not easy to drop, and the heat dissipation effect is poor. When the external environment is humid, the outside air directly enters the distribution box, and the large amount of moisture carried in the air comes into contact with electrical components, which will affect the service life of the electrical components. Summary of the invention

[0005] In order to improve the phenomenon that the heat dissipation effect in the distribution box is poor and the air carries moisture into the distribution box when the outside temperature is high, the present application provides an energy-saving distribution box with good heat dissipation effect.

[0006] The present application provides an energy-saving distribution box with good heat dissipation effect, which adopts the following technical scheme: an energy-saving distribution box with good heat dissipation effect, comprising a box body, a working chamber is provided in the box body, and a box door for closing the working chamber is hinged on the box body.

Then, the cooled air in the first placement chamber re-enters the working chamber through the first connecting pipe and the air outlet chamber, and then the liquid refrigerant enters the cold storage chamber through the second connecting pipe; when the temperature outside the box is high, the hot air in the working chamber passes through the first placement chamber and the first connecting pipe into the second placement chamber, and the liquid refrigerant in the cold storage chamber exchanges heat with the hot air, the temperature of the liquid refrigerant increases, and part of the liquid refrigerant vaporizes and enters the condensation chamber through the second connecting pipe, and the temperature of the hot air decreases and enters the working chamber through the air outlet chamber.

[0008] In the present application, after the external air enters the box, it only circulates in the ventilation duct, which reduces the risk of moisture in the external air entering the working chamber and affecting the life of the electrical components. The cold energy of the cold air can be stored when the temperature outside the box is low, and the stored cold energy can be released when the temperature outside the box is high, thereby increasing the heat dissipation method inside the box. On the one hand, it can save energy and improve the utilization rate of energy.

Based on the described embodiment of the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

The heat exchange plate 123 cools the hot air. At the same time, the cooling mechanism 3 stores the cold energy of the cold air in the ventilation pipe 122. Then, the cooled air in the first placement chamber 12 re-enters the working chamber 11 through the first connecting pipe 14 and the air outlet bin 15. When the temperature outside the box 1 is high, the cooling mechanism 3 releases cold energy to cool the hot air in the working chamber 11.

[0032] In the present application, after the external air enters the box body 1, it only circulates in the vent 13 and the ventilation pipe 122, reducing the risk of moisture in the external air entering the working chamber 11 and affecting the life of the electrical components.

A second placement chamber 16 is opened on the side of the box body 1 away from the first placement chamber 12, and an insulation board is laid on the inner wall of the second placement chamber 16. The second placement chamber 16 can be communicated with the first connecting pipe 14, and the second placement chamber 16 is connected with the air outlet chamber 15 through a one-way valve 31.

A refrigerant is arranged in the cold storage bin 32, and the refrigerant can be anhydrous ether or anhydrous acetone, etc., wherein the fan 121 can work intermittently, and when the temperature in the working chamber 11 drops to the working temperature, the fan 121 stops working.

[0034] When the temperature outside the box 1 is low, the heat exchange plate 123 cools down the gaseous refrigerant in the condensation bin 124, and the gaseous refrigerant is converted into liquid, and then the liquid refrigerant enters the cold storage bin 32 through the second connecting pipe 33; when the temperature outside the box 1 is high, the hot air in the working chamber 11 enters the second placement chamber 16 through the first placement chamber 12 and the first connecting pipe 14, and the liquid refrigerant in the cold storage bin 32 exchanges heat with the hot air, the temperature of the liquid refrigerant increases and part of the liquid refrigerant vaporizes and enters the condensation bin 124 through the second connecting pipe 33, and the temperature of the hot air decreases and enters the working chamber 11 through the air outlet bin 15.

[0035] Reference Figures 2 to 4 A first baffle 4 is hingedly provided on the box body 1 opposite to the vent 13 , and the first baffle 4 can close / open the vent 13 . A moving mechanism 5 is provided in the box body 1 , and the moving mechanism 5 is used to drive the first baffle 4 to rotate.

[0036] The first baffle 4 can prevent rainwater from entering the ventilation pipe 122 on the one hand, and prevent outside air from entering the box 1 when the outside temperature of the box 1 is high on the other hand, thereby reducing the risk of the internal temperature of the box 1 being affected by overheating of the outside air.

[0037] Reference Figures 4 to 6 The moving mechanism 5 includes a first sliding sleeve 51 fixedly connected to the first baffle 4, a sliding rod 52 is slidably connected in the box body 1, a first fixed rod 53 is fixedly connected to the sliding rod 52, the first sliding sleeve 51 is slidably sleeved on the first fixed rod 53, and a linear driver 54 is installed in the box body 1. The telescopic end of the linear driver 54 can drive the sliding rod 52 to move.

[0038] When the vent 13 needs to be opened, the telescopic end of the linear driver 54 moves, driving the sliding rod 52 and the first fixed rod 53 to move toward the second placement cavity 16, and the first fixed rod 53 moves to drive the first baffle 4 to rotate, and the vent 13 opens; when the vent 13 needs to be closed, the telescopic end of the linear driver 54 moves, driving the sliding rod 52 and the first fixed rod 53 to move toward the second placement cavity 16, and the first fixed rod 53 moves to drive the first baffle 4 to rotate, and the vent 13 is closed.

[0039] Reference Figure 2 A second baffle 6 is hingedly provided in the box body 1, and a control mechanism 7 is provided in the box body 1. The control mechanism 7 is used to control the second baffle 6 to cut off the connection between the first connecting pipe 14 and the air outlet bin 15 when the first baffle 4 closes the vent 13.

[0040] By setting the second baffle 6 and the control mechanism 7, when the hot air in the box 1 is cooled only by the refrigerant in the cold storage bin 32, the hot air in the box 1 can enter the working chamber 11 through the air outlet bin 15 after being cooled, thereby reducing the risk of the uncooled hot air directly entering the working chamber 11, which is beneficial to improving the cooling effect and efficiency of the hot air in the working chamber 11.

[0041] Reference Figure 2 , Figure 5 and Figure 6 The control mechanism 7 includes a second sliding sleeve 71 fixedly connected to the second baffle 6, one end of the sliding rod 52 away from the first fixed rod 53 is fixedly connected to the second fixed rod, and the second sliding sleeve 71 is slidably mounted on the second fixed rod.

[0042] When the sliding rod 52 moves in a direction away from the second placement cavity 16, the sliding rod 52 moves and drives the second sliding sleeve 71 to rotate, and the rotation of the second sliding sleeve 71 drives the second baffle 6 to rotate, and then the second baffle 6 separates the first connecting pipe 14 and the air outlet bin 15; when the sliding rod 52 moves in a direction close to the second placement cavity 16, the sliding rod 52 moves and drives the second sliding sleeve 71 to rotate, and the rotation of the second sliding sleeve 71 drives the second baffle 6 to rotate, and then the second baffle 6 releases the partition between the first connecting pipe 14 and the air outlet bin 15.

[0043] Reference Figure 2 , Figure 5 and Figure 6A liquid storage tank 8 is arranged in the first connecting pipe 14, a first heat conducting plate 81 is passed through the middle position of the liquid storage tank 8, a second heat conducting plate 82 is arranged at one end of the liquid storage tank 8, one end of the second heat conducting plate 82 extends into the liquid storage tank 8, and the end of the second heat conducting plate 82 away from the liquid storage tank 8 is located outside the box body 1, a piston rod 83 is slidably connected in the liquid storage tank 8, and heat transfer oil is arranged above the piston rod 83 in the liquid storage tank 8, a T-shaped plate 541 is fixedly connected to the telescopic end of the linear actuator 54, a connecting rod 84 is arranged below the liquid storage tank 8, the middle position of the connecting rod 84 is hingedly arranged on the box body 1, and the two ends of the connecting rod 84 are slidably connected to the T-shaped plate 541 and the piston rod 83 respectively.

[0044] When the outside temperature is low and the telescopic end of the linear driver 54 moves downward, the piston rod 83 can move upward. The upward movement of the piston rod 83 can push the heat transfer oil to move upward so that heat can be conducted between the first heat transfer plate 81 and the second heat transfer plate 82. The cold energy of the outside can cool the high-temperature air through the first heat transfer plate 81, thereby improving the cooling effect and cooling speed of the air; and when the outside temperature is high and the telescopic end of the linear driver 54 moves upward, the piston rod 83 can move downward and can cause the heat transfer oil to move downward, and the heat conduction is blocked between the first heat transfer plate 81 and the second heat transfer plate 82, thereby reducing the influence of the high temperature of the outside on the cooling of the air.

[0045] The implementation principle of an energy-saving distribution box with good heat dissipation effect in the embodiment of the present application is as follows: When the temperature outside the box body 1 is low, the telescopic end of the linear actuator 54 moves, driving the sliding rod 52 and the first fixed rod 53 to move toward the second placement chamber 16 and driving the second sliding sleeve 71 and the T-shaped plate 541 to rotate. The first fixed rod 53 moves, driving the first baffle 4 to rotate, and the vent 13 opens. The second sliding sleeve 71 rotates, driving the second baffle 6 to rotate, and the second baffle 6 releases the partition between the first connecting pipe 14 and the air outlet bin 15. Then, the external cold air enters the ventilation pipe 122 through the vent 13, and the hot air in the working chamber 11 enters the first placement chamber 12 under the action of the fan 121, and the heat exchange is completed. The plate 123 cools down the hot air and the gaseous refrigerant in the condensation bin 124. The gaseous refrigerant in the condensation bin 124 is converted into liquid and enters the cold storage bin 32 through the second connecting pipe 33. The cooled air in the first placement chamber 12 enters the first connecting pipe 14. At the same time, the rotation of the T-shaped plate 541 drives the connecting rod 84 to rotate. The rotation of the connecting rod 84 pushes the piston rod 83 upward to connect the first heat conduction plate 81 and the second heat conduction plate 82. The external cold energy continues to cool down the air entering the first connecting pipe 14 through the second heat conduction plate 82, and then the cooled air re-enters the working chamber 11 through the air outlet bin 15.

[0046] When the temperature outside the box body 1 is high, the telescopic end of the linear drive 54 moves, drives the sliding rod 52 and the first fixed rod 53 to move in the direction away from the second placement chamber 16, and causes the second sliding sleeve 71 and the T-shaped plate 541 to rotate. The movement of the first fixed rod 53 drives the first baffle 4 to rotate, and then the vent 13 is closed. At the same time, the rotation of the second sliding sleeve 71 drives the second baffle 6 to rotate to cut off the connection between the first connecting pipe 14 and the air outlet bin 15. At the same time, the rotation of the T-shaped plate 541 drives the connecting rod 84 to rotate. The rotation of the connecting rod 84 drives the piston rod 83 to move up and down and cuts off the connection between the first heat conducting plate 81 and the second heat conducting plate 82. Then, the hot air in the working chamber 11 passes through the first placement chamber 12 and the first connecting pipe 14 into the second placement chamber 16, and the liquid refrigerant in the cold storage bin 32 exchanges heat with the hot air. The temperature of the liquid refrigerant increases and part of the liquid refrigerant vaporizes and enters the condensation bin 124 through the second connecting pipe 33. The temperature of the hot air decreases and enters the working chamber 11 through the air outlet bin 15.
