Description
Technical Field
[0001] The present invention relates to the technical field of energy-saving distribution boxes, and in particular 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 environmental influences such as moisture and dust. These boxes typically contain various electrical components, such as circuit breakers, contactors, and transformers, which generate significant heat during operation. Optimizing heat dissipation to protect internal components from overheating and reduce unnecessary energy consumption is crucial for ensuring the proper functioning of these components, particularly in high-temperature environments or under prolonged, high-load conditions.
[0003] Current cooling solutions for distribution boxes on the market primarily use fans or other mechanical devices to forcibly expel heat. While this method significantly improves cooling efficiency, long-term operation can lead to noise pollution and increased vibration risks, potentially damaging sensitive electronic components. Furthermore, the continuous operation of the fans increases energy consumption and maintenance costs. Summary of the Invention
[0004] In order to overcome the shortcomings 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 opened at the top and bottom of the distribution box, a fan is fixedly connected to the side of the distribution box near the top opening, an air guide frame is fixedly connected to the distribution box and is symmetrically distributed along the distribution box, a motor is fixedly connected to the air guide frame, a rotating frame is rotatably connected inside the air guide frame, the output shaft of the motor is fixedly connected to the adjacent rotating frame, a first air outlet is opened on the air guide frame, a plurality of longitudinally arranged air inlet holes are opened on the side of the distribution box near the air guide frame, a heat dissipation channel symmetrically distributed along the distribution box is opened in the distribution box, the first air outlet and the air inlet hole are both connected to the adjacent heat dissipation channel, a second air outlet symmetrically distributed along the distribution box is opened on the side of the distribution box near the fan, the heat dissipation channel is connected to the adjacent second air outlet, the air inlet hole and the second air outlet are both connected to the inside of the distribution box, a temperature sensor is fixedly connected to the inside of the distribution box, and the temperature sensor is electrically connected to the fan through a control module.
[0006] In a preferred embodiment of the present invention, a lifting plate is further included for blocking the top opening of the distribution box. The lifting plate is slidably connected to the outside of the distribution box on one side close to the top opening. The distribution box is fixed with cylinders symmetrically distributed along the distribution box. The telescopic ends of the cylinders are fixed to the lifting plate, and 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 a rotating plate symmetrically distributed along the distribution box, and the rotating plate is rotatably connected to one side of the inner top of the distribution box close to the bottom of the fan.
[0008] In a preferred embodiment of the present invention, the symmetrical rotating plates contact each other and form a V-shape when in contact, for directing the hot air toward the second air outlet.
[0009] In a preferred embodiment of the present invention, it also 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 rotating plate, and a movable hole is opened on the top of the distribution box for the connecting rod to pass through and move.
[0010] In a preferred embodiment of the present invention, it also includes opening and closing plates symmetrically distributed along the distribution box, which 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 to block the bottom opening of the distribution box.
[0011] In a preferred embodiment of the present invention, a U-shaped pull frame is further included, which is fixedly connected to the lifting plate, and a fixed frame is fixedly connected to the side of the opening and closing plate close to the pull frame. A rotating rod symmetrically distributed along the pull frame is rotatably connected to the side of the distribution box close to the fixed frame. Both the pull frame and the fixed frame are grooved, and one end of the rotating rod is movably connected to the groove of the pull frame, and the other end of the rotating rod is movably connected to the slot of the adjacent fixed frame.
[0012] In a preferred embodiment of the present invention, it further comprises a plurality of heat sinks symmetrically distributed along the distribution box, and the heat sinks are fixedly connected to the distribution box.
[0013] Compared with the existing technology, the present invention has the following advantages: the present invention mainly uses a slight rotation of the rotating frame to allow the gas flow in the heat dissipation channel to form a low-pressure area, and uses the negative pressure adsorption force to discharge the hot air, rather than relying on the fan to blow out strong wind to discharge the hot air, so it is quieter, thus reducing vibration and noise during heat dissipation, and also optimizing the heat dissipation mechanism to reduce unnecessary energy consumption. In order to take into account efficient heat dissipation, the fan is temporarily started for heat dissipation when the temperature is too high, which greatly reduces the fan operation time, noise and energy consumption.
[0014] The present invention uses a lifting plate to block the top opening of the distribution box and uses an opening and closing plate to block the bottom opening of the distribution box to reduce dust from entering the distribution box. When the fan is turned on, the lifting plate and the opening and closing plate are automatically opened to avoid affecting the air flow when the fan blows air to dissipate heat.
[0015] The present invention utilizes two V-shaped rotating plates to guide the hot air inside the distribution box to the second air outlet, thereby achieving a heat conduction effect. The rotating plate is located below the fan to block dust from the bottom of the fan. When the fan is turned on, the rotating plate automatically opens without affecting air circulation during heat dissipation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0027] Although the present invention may be described with respect to a specific application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those skilled in the art will recognize that terms such as "above," "below," "upwardly," "downwardly," and the like are used to describe the drawings and are not intended to limit the scope of the present invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and are not intended to limit the scope of the present invention in any way.
[0028] Example 1: A sealed distribution box with multi-stage linkage heat dissipation, such as Figures 1-4 As shown, it includes a distribution box 101, the top and bottom of the distribution box 101 are opened, a fan 102 is fixedly connected to one side of the distribution box 101 near the top opening, the outer lower side of the distribution box 101 is fixedly connected to air guide frames 103 symmetrically distributed along the left and right sides of the distribution box 101, the rear sides of the left and right air guide frames 103 are fixedly connected to motors 104, a rotating frame 105 is rotatably connected inside the air guide frame 103, the output shaft of the motor 104 is fixedly connected to the adjacent rotating frame 105, a first air outlet 106 is opened on the top of the air guide frame 103, and a plurality of longitudinally arranged air inlet holes 107 are opened on the left and right sides of the interior of the distribution box 101, and the air inlet holes 107 are set as inclined holes. The electrical box 101 is provided with a heat dissipation channel 108 which is symmetrically distributed along the left and right sides of the distribution box 101. The first air outlet 106 and the air inlet 107 are both connected to the adjacent heat dissipation channel 108. The upper side of the distribution box 101 is provided with a second air outlet 109 which is symmetrically distributed along the left and right sides of the distribution box 101. The heat dissipation channel 108 is connected to the adjacent second air outlet 109. The air inlet 107 and the second air outlet 109 are both connected to the inside of the distribution box 101. The air inlet 107 guides the hot air in the distribution box 101 obliquely upward to the second air outlet 109. A temperature sensor 110 is fixedly connected to the right side of 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, and the output shaft of the motor 104 drives the rotating frame 105 to rotate slowly, so that the external natural wind enters the wind guide frame 103, and then flows upward into the heat dissipation channel 108 through the first air outlet 106, and finally is discharged through the second air outlet 109. Since the air flow rate in the heat dissipation channel 108 is faster than the flow rate of the hot air in the distribution box 101, according to the Bernoulli principle, the faster the flow rate, the lower the air pressure in the area. Therefore, under the negative pressure suction of the low-pressure area, part of the hot air in the distribution box 101 is directly discharged through the second air outlet 109, and the other part is discharged directly through the second air outlet 109. The hot air is sucked obliquely upward into the heat dissipation channel 108 through the air inlet holes 107 on the left and right sides, and then discharged through the second air outlet 109, thus achieving a heat dissipation effect. Compared with the top fan 102 that directly blows out the hot air inside, this structure only needs to slightly rotate the rotating frame 105 to make the gas flow in the heat dissipation channel 108 form a low-pressure area, and use the negative pressure adsorption force to discharge the hot air, instead of relying on the fan 102 to blow out strong wind to discharge the hot air. Therefore, it is quieter, thus reducing vibration and noise during heat dissipation, and optimizing the heat dissipation mechanism to reduce unnecessary energy consumption.
[0030] If the distribution box 101 is seriously heated, it will be temporarily switched to the fan 102 cooling mode, which will greatly reduce the working time of the fan 102 and take into account efficient heat dissipation. The switching operation is as follows: When the temperature in 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 air downward, so that the hot air in the distribution box 101 is discharged through the bottom opening. When the temperature in the distribution box 101 is lower than the preset value, the fan 102 is controlled to be turned off.
[0031] Example 2: Based on Example 1, Figure 5 and Figure 6 As shown, it also 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 along the up and down directions. The top of the distribution box 101 is fixed with cylinders 202 symmetrically distributed along the left and right sides of the distribution box 101. The telescopic end of the cylinder 202 is fixed to the lifting plate 201, and the temperature sensor 110 is electrically connected to the cylinder 202 through the control module.
[0032] Initially, the top opening of the distribution box 101 is blocked by the lifting plate 201 to block dust on 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 to move upward, and then opening the top opening of the distribution box 101, so that air can flow downward when the fan 102 blows.
[0033] like Figure 7 and Figure 8 As shown, it also includes connecting rods 301 distributed symmetrically along the lifting plate 201. There are four connecting rods 301 in total, and the upper ends of the connecting rods 301 are rotatably connected to the lifting plate 201. A movable hole for the connecting rods 301 to pass through and move is opened on the top of the distribution box 101. The inner top of the distribution box 101 is rotatably connected to the rotating plates 302 distributed symmetrically along 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 symmetrical rotating plates 302 contact each other and form a V-shape when in contact, which is used to guide the hot air obliquely upward to the second air outlet 109.
[0034] When the two rotating plates 302 contact each other, they form a V shape, which can guide the hot air inside the distribution box 101 to the second air outlet 109, thereby achieving a heat conduction effect. The rotating plate 302 is located below the fan 102 to block dust from the bottom of the fan 102. When the fan 102 is turned on, the lifting plate 201 rises and pulls the rotating plate 302 downward to rotate and open through the connecting rod 301, thereby no longer blocking the bottom of the fan 102, allowing air to flow downward when the fan 102 blows air to dissipate heat.
[0035] like Figure 9 and Figure 10 As shown, it also includes a U-shaped pulling rack 401, the pulling rack 401 is fixedly connected to the lifting plate 201, and the side of the distribution box 101 near the bottom opening is rotatably connected to an opening and closing plate 402 symmetrically distributed along the left and right sides of the distribution box 101. The left and right symmetrical opening and closing plates 402 contact each other and are used to block the bottom opening of the distribution box 101. The rear side of the opening and closing plate 402 is fixedly connected to a fixing rack 403, and the rear side of the lower part of the distribution box 101 is rotatably connected to a rotating rod 404 symmetrically distributed along the pulling rack 401. The pulling rack 401 and the fixing rack 403 are both grooved, and one end of the rotating rod 404 is movably connected to the groove of the pulling rack 401, and the other end of the rotating rod 404 is movably connected to the groove of the adjacent fixing rack 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 lifting plate 201 rises and pulls the rotating rod 404 to rotate through the pull frame 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, so that when the fan 102 blows air to dissipate heat, air can flow out through the bottom opening.
[0037] The power distribution box 101 further includes a plurality of heat sinks 501 symmetrically distributed along the left and right sides of the power distribution box 101 . The heat sinks 501 are fixedly connected to the power distribution box 101 . The heat conduction of the heat sinks 501 can accelerate the heat dissipation inside the power distribution box 101 .
[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
