Description

Technical Field

[0001] The present invention relates to the technical field of energy-saving distribution boxes, and particularly to a sealed distribution box with multi-stage linkage heat dissipation. Background Art

[0002] Sealed distribution boxes are widely used in industrial, commercial, and residential environments to protect electrical equipment from the external environment (such as moisture, dust, etc.). These distribution boxes usually contain various electrical components, such as circuit breakers, contactors, and transformers, which generate a large amount of heat during operation. Especially in high-temperature environments or under long-term high-load working conditions, how to optimize the heat dissipation mechanism to protect the internal electrical components from overheating damage and reduce unnecessary energy consumption to save energy has become a key issue to ensure the normal operation of the electrical components in the distribution box.

[0003] Currently, the heat dissipation solutions for distribution boxes on the market mainly use fans or other mechanical devices to forcibly discharge hot air. Although this method can significantly improve the heat dissipation efficiency, long-term operation will cause noise pollution and increase the risk of vibration, which may damage sensitive electronic components; in addition, the continuous operation of the fan will also increase energy consumption and maintenance costs. Summary of the Invention

[0004] In order to overcome the disadvantages of energy consumption and noise pollution, the present invention provides a sealed distribution box with multi-stage linkage heat dissipation.

[0005] A sealed distribution box with multi-stage linkage heat dissipation includes a distribution box. Openings are provided at both the top and bottom of the distribution box. A fan is fixedly connected to one side of the distribution box near the top opening. Guide airframes are fixedly connected to the distribution box and are symmetrically distributed along the distribution box. Motors are fixedly connected to the guide airframes. A rotating frame is rotatably connected inside the guide airframe. The output shaft of the motor is fixedly connected to the adjacent rotating frame. First air vents are provided on the guide airframes. A number of longitudinally arranged air inlet holes are provided on the side of the interior of the distribution box near the guide airframe. Heat dissipation channels are provided inside the distribution box and are symmetrically distributed along the distribution box. The first air vents and the air inlet holes are both communicated with the adjacent heat dissipation channels. Second air vents are provided on one side of the distribution box near the fan and are symmetrically distributed along the distribution box. The heat dissipation channels are communicated with the adjacent second air vents. The air inlet holes and the second air vents are both communicated with the interior of the distribution box. A temperature sensor is fixedly connected inside the distribution box. The temperature sensor is electrically connected to the fan through a control module.

[0006] In a preferred embodiment of the present invention, it further includes a lifting plate for blocking the top opening of the distribution box. The lifting plate is slidably connected to the outside of one side of the distribution box near the top opening. Cylinders are fixedly connected to the distribution box and are symmetrically distributed along the distribution box. The telescopic end of the cylinder is fixedly connected to the lifting plate. The temperature sensor is electrically connected to the cylinder through a control module.

[0007] In a preferred embodiment of the present invention, it further includes turning plates symmetrically distributed along the distribution box. The turning plates are rotatably connected to one side of the inner top of the distribution box near the bottom of the fan.

[0008] In a preferred embodiment of the present invention, the symmetrical turning plates are in contact with each other, and when in contact, they jointly form a V shape for guiding the hot air to the second air outlet.

[0009] In a preferred embodiment of the present invention, it further includes connecting rods symmetrically distributed along the lifting plate. One end of the connecting rod is rotatably connected to the lifting plate, and the other end of the connecting rod is rotatably connected to the adjacent turning plate. An activity hole for the connecting rod to penetrate and move is opened at the top of the distribution box.

[0010] In a preferred embodiment of the present invention, it further includes opening and closing plates symmetrically distributed along the distribution box. The opening and closing plates are rotatably connected to one side of the distribution box near the bottom opening. The symmetrical opening and closing plates are in contact with each other for blocking the bottom opening of the distribution box.

[0011] In a preferred embodiment of the present invention, it further includes a U-shaped pulling frame fixedly connected to the lifting plate. A fixing frame is fixedly connected to one side of the opening and closing plate close to the pulling frame. On one side of the distribution box near the fixing frame, there are turning rods symmetrically distributed along the pulling frame rotatably connected. Both the pulling frame and the fixing frame are provided with slots, and one end of the turning rod is movably connected to the slot of the pulling frame, and the other end of the turning rod is movably connected to the slot of the adjacent fixing frame.

[0012] In a preferred embodiment of the present invention, it further includes a plurality of heat sinks symmetrically distributed along the distribution box. The heat sinks are fixedly connected to the distribution box.

[0013] Compared with the prior art, the present invention has the following advantages: The present invention mainly makes the gas flow in the heat dissipation channel form a low-pressure area by slightly rotating the turning frame, and uses the negative pressure adsorption force to discharge the hot air, rather than relying on the strong wind blown by the fan to discharge the hot air. Therefore, it is quieter, so as to reduce the vibration and noise during heat dissipation, and also optimizes the heat dissipation mechanism to reduce unnecessary energy consumption. And in order to give consideration to efficient heat dissipation, the fan is temporarily started for heat dissipation only when the temperature is too high, greatly reducing the fan operation time and reducing noise and energy consumption.

[0014] The present invention uses the lifting plate to block the top opening of the distribution box, and uses the opening and closing plate to block the bottom opening of the distribution box to reduce dust from entering the distribution box. And when the fan is turned on, the lifting plate and the opening and closing plate are automatically opened to avoid affecting the air flow during the fan blowing heat dissipation.

[0015] The present invention uses two turning plates arranged in a V shape to guide the hot air inside the distribution box to the second air outlet, so as to achieve a heat conduction effect. And the turning plates are located below the fan to block dust at the bottom of the fan, and when the fan is turned on, the turning plates are automatically opened without affecting the air circulation during heat dissipation.

[0027] Although the present invention may be described with respect to specific applications or industries, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as "above", "below", "upward", "downward", etc. are used to describe the drawings and do not represent a limitation on the scope of the present invention defined by the appended claims. Any numerical labels such as "first" or "second" are merely illustrative and are not intended to limit the scope of the present invention in any way.

[0028] Embodiment 1: A sealed distribution box with multi-stage linkage heat dissipation, as Figures 1-4 shown, which includes a distribution box 101. Openings are provided at both the top and bottom of the distribution box 101. A fan 102 is fixedly connected to one side of the distribution box 101 near the top opening. Guide wind frames 103 symmetrically distributed left and right along the distribution box 101 are fixedly connected to the lower side of the outside of the distribution box 101. Motors 104 are fixedly connected to the rear sides of the left and right guide wind frames 103. A rotating frame 105 is rotatably connected inside the guide wind frame 103. The output shaft of the motor 104 is fixedly connected to the adjacent rotating frame 105. A first air outlet 106 is provided at the top of the guide wind frame 103. A plurality of longitudinally arranged air inlet holes 107 are provided on both left and right sides inside the distribution box 101. The air inlet holes 107 are inclined holes. Heat dissipation channels 108 symmetrically distributed left and right along the distribution box 101 are provided inside the distribution box 101. The first air outlet 106 and the air inlet holes 107 are both communicated with the adjacent heat dissipation channels 108. Second air outlets 109 symmetrically distributed left and right along the distribution box 101 are provided on the upper side of the distribution box 101. The heat dissipation channels 108 are communicated with the adjacent second air outlets 109. The air inlet holes 107 and the second air outlets 109 are both communicated with the inside of the distribution box 101. The air inlet holes 107 direct the hot air inside the distribution box 101 obliquely upward to the second air outlets 109. A temperature sensor 110 is fixedly connected to the right side inside the distribution box 101. The temperature sensor 110 is electrically connected to the fan 102 through a control module.

[0029] Initially, only the motor 104 is turned on. The output shaft of the motor 104 drives the rotating frame 105 to rotate slowly, so that the external natural wind enters the guide wind frame 103, then flows upward into the heat dissipation channels 108 through the first air outlet 106, and finally is discharged through the second air outlets 109. Since the air flow rate in the heat dissipation channels 108 is faster than the air flow rate of the hot air inside the distribution box 101, according to Bernoulli's principle, the pressure in the area with faster flow rate is lower. Therefore, under the negative pressure suction force in the low-pressure area, a part of the hot air inside the distribution box 101 is directly discharged through the second air outlets 109, and another part of the hot air is obliquely upward sucked into the heat dissipation channels 108 through the air inlet holes 107 on the left and right sides, and then discharged through the second air outlets 109. In this way, the heat dissipation effect is achieved. Compared with the fan 102 at the top directly blowing out the internal hot air, this structure only needs the rotating frame 105 to rotate slightly to make the gas flow in the heat dissipation channels 108 form a low-pressure area, and uses the negative pressure adsorption force to discharge the hot air, rather than relying on the fan 102 to blow out strong wind to discharge the hot air. Therefore, it is quieter, so the vibration and noise during heat dissipation are reduced, and the heat dissipation mechanism is also optimized to reduce unnecessary energy consumption.

[0030] If the distribution box 101 overheats severely, temporarily switch to the cooling mode of the fan 102, which greatly reduces the working time of the fan 102 and can also achieve efficient heat dissipation. The switching operation is as follows: When the temperature inside the distribution box 101 is higher than the preset value, the temperature sensor 110 sends an electrical signal. The control module receives the electrical signal and controls the fan 102 to start. The fan 102 blows downward, so that the hot air inside the distribution box 101 is discharged through the bottom opening. When the temperature inside the distribution box 101 is lower than the preset value, the fan 102 is controlled to turn off.

[0031] Embodiment 2: On the basis of Embodiment 1, as Figure 5 and Figure 6 shown, it further includes a lifting plate 201 for blocking the top opening of the distribution box 101. The lifting plate 201 is slidably connected to the outside of the distribution box 101 near the top opening in the vertical direction. Cylinders 202 symmetrically distributed along the left and right sides of the distribution box 101 are fixedly connected to the top of the distribution box 101. The telescopic ends of the cylinders 202 are fixedly connected to the lifting plate 201. The temperature sensor 110 and the cylinders 202 are electrically connected through the control module.

[0032] Initially, the top opening of the distribution box 101 is blocked by the lifting plate 201 to prevent dust from entering the top of the fan 102. When the fan 102 is turned on, the temperature sensor 110 simultaneously controls the telescopic rod of the cylinder 202 to extend upward, thereby pushing the lifting plate 201 upward and then opening the top opening of the distribution box 101, so that air can flow downward when the fan 102 blows.

[0033] As Figure 7 and Figure 8 shown, it further includes connecting rods 301 symmetrically distributed along the left and right sides of the lifting plate 201. There are four connecting rods 301 in total. The upper ends of the connecting rods 301 are rotatably connected to the lifting plate 201. The top of the distribution box 101 is provided with moving holes for the connecting rods 301 to pass through and move. The inner top of the distribution box 101 is rotatably connected with rotating plates 302 symmetrically distributed along the left and right sides of the distribution box 101. The rotating plates 302 are located below the bottom of the fan 102. The lower ends of the connecting rods 301 are rotatably connected to the adjacent rotating plates 302. The symmetrically distributed rotating plates 302 are in contact with each other, and when in contact, they jointly form a V shape for guiding the hot air obliquely upward to the second air outlet 109.

[0034] When the two rotating plates 302 are in contact with each other, they form a V shape, which can guide the hot air inside the distribution box 101 to the second air outlet 109, thus achieving a heat conduction effect. Moreover, the rotating plates 302 are located below the fan 102 to prevent dust from entering the bottom of the fan 102. When the fan 102 is turned on, the upward movement of the lifting plate 201 will pull the rotating plates 302 to rotate downward and open through the connecting rods 301, so that the bottom of the fan 102 is no longer blocked, and air can flow downward when the fan 102 blows for heat dissipation.

[0035] AsFigure 9 and Figure 10 As shown in Figure 10 , it further includes a U-shaped stay 401. The stay 401 is fixedly connected to the lifting plate 201. On one side close to the bottom opening in the distribution box 101, there are opening and closing plates 402 rotatably connected, which are symmetrically distributed left and right along the distribution box 101. The left and right symmetric opening and closing plates 402 are in contact with each other to block the bottom opening of the distribution box 101. A fixed frame 403 is fixedly connected to the rear side of the opening and closing plate 402. On the rear side of the lower part in the distribution box 101, there are rotating rods 404 rotatably connected, which are symmetrically distributed left and right along the stay 401. Both the stay 401 and the fixed frame 403 are provided with slots, and one end of the rotating rod 404 is movably connected to the slot of the stay 401, and the other end of the rotating rod 404 is movably connected to the slot of the adjacent fixed frame 403.

[0036] Initially, the bottom opening of the distribution box 101 is blocked by the opening and closing plate 402 to reduce dust from entering the distribution box 101. When the fan 102 is turned on, the upward movement of the lifting plate 201 will drive the rotating rod 404 to rotate through the stay 401, thereby driving the opening and closing plate 402 to rotate downward and open, so that the bottom opening of the distribution box 101 is no longer blocked, and when the fan 102 blows air for heat dissipation, the air can flow out through the bottom opening.

[0037] It further includes a number of heat sinks 501 symmetrically distributed left and right along the distribution box 101. The heat sinks 501 are fixedly connected to the distribution box 101. By conducting heat through the heat sinks 501, the heat dissipation inside the distribution box 101 can be accelerated.

[0038] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
