Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation structures, in particular to a heat dissipation structure of a series reactor. Background Art

[0002] A series reactor is a common circuit element, which is composed of multiple reactors connected in series. Its working principle is to use the induction principle of the inductor to form an impedance in the circuit, hindering the change of current in the circuit. When the voltage in the circuit changes, the current in the series reactor will also change, and the magnetic field in the inductor will change accordingly, thereby generating a reverse potential.

[0003] In the existing technology, when the reactor is heat-dissipated, a common and direct method is to use an exhaust fan for heat dissipation. However, although this method can reduce the temperature of the reactor to a certain extent, the exhaust fan will continuously blow the surrounding air into the reactor during operation. However, there is usually a large amount of dust and particles in the environment. These tiny particles will be brought into the reactor with the flow of air. As time goes by, these dusts will continue to accumulate on the coil of the reactor and even penetrate into the internal structure of the coil. The adhesion of dust will hinder the heat transfer on the surface of the coil, resulting in the inability to effectively dissipate the heat to the external environment, which will increase the temperature of the reactor and affect its performance and life. In addition, when dust penetrates into the coil, it may cause electrical faults, such as short circuit, insulation breakdown, etc., which seriously threatens the safe operation of the reactor. It is necessary to propose a heat dissipation structure suitable for series reactors. Utility Model Content

[0004] The utility model aims to provide a heat dissipation structure of a series reactor to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A heat dissipation structure for a series reactor comprises a reactor body, the bottom of which is provided with a base; a dustproof shell is provided on the outside of the reactor body, the dustproof shell is connected to the base of the reactor body by screws, a plurality of heat dissipation fans are fixedly mounted on one side of the dustproof shell, and an air inlet end of the heat dissipation fan is located inside the dustproof shell; a through hole is provided on a side of the dustproof shell away from the heat dissipation fan, an air inlet square tube is fixedly connected to a side wall of the dustproof shell at a position where the through hole is located, a filter component is provided inside the air inlet square tube, and the filter component is used for filtering air passing through the air inlet square tube; a transfer tube is provided at the bottom of the air inlet square tube, and a dust collecting cylinder for collecting dust is detachably connected to the bottom of the transfer tube.

[0007] By adopting the above technical solution, a dustproof shell is provided to protect the reactor body, and a special airflow channel is provided for exhaust and air intake, so that the external air can enter the dustproof shell after filtering through the special channel, and the heat is discharged to the outside through the cooling fan, thereby avoiding the situation where dust adheres to and penetrates into the coil and affects the heat dissipation effect, thereby greatly improving the heat dissipation effect of the reactor body.

[0008] A further improvement of the technical solution of the utility model is that the filtering component includes a first guide plate, which is fixedly connected between the top end and both sides of the inner wall of the air intake square tube, and a filter net is fixedly connected between the ground end and both sides of the inner wall of the air intake square tube, and the top wall of the filter net is in close contact with the bottom of the first guide plate.

[0009] By adopting the above technical solution, by setting a filter component, the air passing through the air intake square tube can be filtered, so that dust can be filtered out before entering the dustproof shell, thereby preventing dust from directly entering the reactor body and affecting its normal operation.

[0010] A further improvement of the technical solution of the utility model is that the first guide plate portion is configured as an arc-shaped plate, and the downward extension direction of the arc-shaped plate is the air intake direction, a second guide plate is fixedly connected between the bottom and both sides of the inner wall of the air intake square tube, and the second guide plate is centrally symmetrically arranged with the first guide plate in the vertical direction.

[0011] By adopting the above technical solution, when air passes through the air intake square tube, it is blocked by the second guide plate and thus only enters from the upper half; the air is then guided by the first guide plate, so that the air produces a swirling effect, causing the dust to be thrown horizontally while being sucked inside the dustproof shell. Since the gravity of the dust is greater than that of the air, most of the dust falls downward into the dust collecting barrel during the above process.

[0012] A further improvement of the technical solution of the utility model is that the filter screen is arranged obliquely, and the part close to the top is close to the air inlet direction.

[0013] By adopting the above technical solution, the dust has a longer movable channel before contacting the filter, so as to increase the amount of dust falling downward under the action of gravity; and when the dust adheres to the inclined filter, it will be easier to fall freely downward under the action of gravity when the wind force decreases.

[0014] A further improvement of the technical solution of the utility model is that: the top end of the dust collecting barrel is fixedly connected to a second docking ring, the outer side of the second docking ring is threaded, the bottom end of the adapter tube is fixedly connected to the first docking ring, the outer side of the adapter tube is sleeved with an internal threaded sleeve, and the dust collecting barrel and the adapter tube are connected by the internal threaded sleeve and the thread on the second docking ring.

[0015] By adopting the above technical solution, the internal threaded sleeve is rotated to release the connection between the internal threaded sleeve and the second docking ring, and then the dust collecting bin can be removed. After cleaning, the second docking ring is fit with the first docking ring, and the internal threaded sleeve is rotated again to connect the second docking ring with the internal threaded sleeve, and the installation of the dust collecting bin is completed.

[0016] A further improvement of the technical solution of the utility model is that a screw is rotatably connected between the two sides of the inner wall of the square air intake tube, a sliding rod is also fixedly connected between the two sides of the inner wall of the square air intake tube, a slider is threadedly connected to the outer side of the screw, the slider is slidably connected to the sliding rod, a brush is fixedly connected to one side of the slider, and one end of the screw extends to the outside of the square air intake tube and is fixedly connected to a knob.

[0017] By adopting the above technical solution, when the cooling fan stops working, the knob is turned to rotate the screw, and the slider drives the brush to move along the axial direction of the slider, thereby cleaning the filter to make the dust fall off and fall into the dust collecting bin.

[0018] A further improvement of the technical solution of the utility model is that: a controller is fixedly connected to one side of the dustproof shell, a temperature sensor is installed inside the dustproof shell, and the cooling fan and the temperature sensor are both electrically connected to the controller.

[0019] By adopting the above technical solution, it is convenient to monitor the temperature inside the dustproof shell in real time through the temperature sensor, so as to flexibly control the rotation speed of the cooling fan through the controller.

[0020] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0021] 1. The utility model provides a heat dissipation structure of a series reactor, which protects the reactor body by setting a dustproof shell, and sets a special airflow channel for exhaust and air intake, so that the external air can enter the dustproof shell after filtering through the special channel, and the heat is discharged to the outside through the heat dissipation fan, thereby avoiding the situation where dust adheres and penetrates into the coil to affect the heat dissipation effect, and greatly improves the heat dissipation effect of the reactor body.

[0022] 2. The utility model provides a heat dissipation structure of a series reactor. By setting two guide plates, when air passes through the air intake square tube, it is blocked by the second guide plate and thus only enters from the upper half; the air is then guided by the first guide plate, so that the air produces a swirling effect, so that the dust is thrown horizontally while being sucked inside the dustproof shell. Since the gravity of the dust is greater than that of the air, most of the dust falls downward into the dust collecting tube during the above process.

[0023] 3. The utility model provides a series reactor heat dissipation structure. By arranging a brush, the knob can be turned regularly when the cooling fan stops working, so that the screw rotates, and then the slider drives the brush to move along the axial direction of the slide rod, and then the filter is cleaned, so that the dust falls off and falls into the dust collecting barrel, so as to facilitate cleaning of the dust on the filter.

[0032] The present invention is further described in detail below in conjunction with the embodiments:

[0033] like Figure 1-Figure 6As shown, the utility model provides a heat dissipation structure of a series reactor, including a reactor body 1, the bottom of the reactor body 1 is provided with a base; the outside of the reactor body 1 is covered with a dustproof shell 2, the dustproof shell 2 is connected to the base of the reactor body 1 by screws, a plurality of heat dissipation fans 17 are fixedly installed on one side of the dustproof shell 2, and the air inlet end of the heat dissipation fan 17 is located inside the dustproof shell 2; a through hole is opened on the side of the dustproof shell 2 away from the heat dissipation fan 17, and an air intake square tube 3 is fixedly connected to the side wall of the dustproof shell 2 at the position where the through hole is located, and a filter component is arranged inside the air intake square tube 3, and the filter component is used to filter the air passing through the air intake square tube 3; a transfer tube 7 is arranged at the bottom of the air intake square tube 3, and a dust collecting cylinder 9 for collecting dust is detachably connected to the bottom of the transfer tube 7.

[0034] In this embodiment, a dustproof cover 2 is provided to protect the reactor body 1, and a special airflow channel is provided for exhaust and intake, so that external air can enter the dustproof cover 2 after filtering through a special channel (the air intake square tube 3), and the heat is discharged to the outside through the cooling fan 17, thereby avoiding the situation where dust adheres to and penetrates into the coil to affect the heat dissipation effect, thereby greatly improving the heat dissipation effect of the reactor body 1.

[0035] like Figure 5 and Figure 6 As shown, preferably, the filtering component includes a first guide plate 4, which is fixedly connected between the top and both sides of the inner wall of the air inlet square tube 3, and a filter screen 6 is fixedly connected between the ground end and both sides of the inner wall of the air inlet square tube 3, and the top wall of the filter screen 6 is in close contact with the bottom of the first guide plate 4.

[0036] In this embodiment, by providing a filter component, the air passing through the air intake square tube 3 can be filtered, so that dust can be filtered out before entering the dustproof shell 2, thereby preventing dust from directly entering the reactor body 1 and affecting its normal operation.

[0037] like Figure 5 and Figure 6 As shown, based on Example 1, the utility model provides a technical solution: preferably, the first guide plate 4 is partially configured as an arc-shaped plate, and the downward extension direction of the arc-shaped plate is the air intake direction, and a second guide plate 5 is fixedly connected between the bottom and both sides of the inner wall of the air intake square tube 3, and the second guide plate 5 and the first guide plate 4 are centrally symmetrically arranged in the vertical direction.

[0038] In this embodiment, when air passes through the air inlet square tube 3, it is blocked by the second guide plate 5 and thus only enters from the upper half; it is then guided by the first guide plate 4 so that the air produces a swirling effect, causing the dust to be thrown horizontally while being sucked inside the dustproof shell 2. Since the gravity of the dust is greater than that of the air, most of the dust falls downward into the dust collecting barrel 9 during the above process.

[0039] like Figure 5 and Figure 6 As shown, based on Example 2, the utility model provides a technical solution: preferably, the filter screen 6 is arranged obliquely, and the part close to the top is close to the air intake direction.

[0040] In this embodiment, the dust has a longer active channel before contacting the filter 6 to increase the amount of dust falling downward under the action of gravity; and when the dust adheres to the inclined filter 6, it will be easier to fall freely downward under the action of gravity when the wind force decreases.

[0041] like Figure 4 and Figure 5 As shown, on the basis of Example 3, the utility model provides a technical solution: preferably, the top end of the dust collecting barrel 9 is fixedly connected with a second docking ring 10, the outer side of the second docking ring 10 is threaded, the bottom end of the adapter tube 7 is fixedly connected with the first docking ring 8, the outer side of the adapter tube 7 is sleeved with an internal threaded sleeve 11, and the dust collecting barrel 9 and the adapter tube 7 are connected by the internal threaded sleeve 11 and the thread on the second docking ring 10.

[0042] In this embodiment, the internal threaded sleeve 11 is rotated to release the connection with the second docking ring 10, so that the dust collecting bin 9 can be removed. After cleaning, the second docking ring 10 is fitted with the first docking ring 8, and the internal threaded sleeve 11 is rotated again to connect the second docking ring 10 with the internal threaded sleeve 11, and the installation of the dust collecting bin 9 is completed.

[0043] like Figure 5 and Figure 6 As shown, on the basis of Example 4, the utility model provides a technical solution: preferably, a screw rod 12 is rotatably connected between the two sides of the inner wall of the air intake square tube 3, a slide rod 13 is also fixedly connected between the two sides of the inner wall of the air intake square tube 3, a slider 14 is threadedly connected to the outer side of the screw rod 12, the slider 14 is slidably connected to the slide rod 13, a brush 15 is fixedly connected to one side of the slider 14, and one end of the screw rod 12 extends to the outside of the air intake square tube 3 and is fixedly connected to a knob.

[0044] When air enters the dustproof housing 2 through the air inlet square tube 3, a small amount of dust will still be drawn onto the filter screen 6, which will inevitably affect the ventilation effect as it accumulates over a long period of time.

[0045] In this embodiment, when the cooling fan 17 stops working, the knob is turned to rotate the screw 12, so that the slider 14 drives the brush 15 to move along the axial direction of the slide rod 13, thereby cleaning the filter 6 to make the dust fall off and fall into the dust collecting bin 9.

[0046] like Figure 1 and Figure 2 As shown, preferably, a controller 16 is fixedly connected to one side of the dustproof shell 2 , a temperature sensor is installed inside the dustproof shell 2 , and the cooling fan 17 and the temperature sensor are both electrically connected to the controller 16 .

[0047] In this embodiment, the temperature condition inside the dustproof housing 2 is conveniently monitored in real time by the temperature sensor, so that the rotation speed of the cooling fan 17 can be flexibly controlled by the controller 16 .

[0048] The working principle of the heat dissipation structure of the series reactor is described in detail below.

[0049] like Figure 1-Figure 6 As shown, the cooling fan 17 is controlled to work so as to draw the air and heat inside the dustproof shell 2 outward. During the process, the external air enters the dustproof shell 2 through the air intake square tube 3 for air balance. When the air passes through the air intake square tube 3, it is blocked by the second guide plate 5, so it only enters from the upper half. Then it is guided by the first guide plate 4 so that the air will produce a swirling effect, so that the dust is thrown horizontally while being sucked inside the dustproof shell 2. Since the gravity of the dust is greater than that of the air, most of the dust falls downward into the dust collecting barrel 9 during the above process. A sealing ring is provided at the connection between the dust collecting barrel 9 and the transfer tube 7. The air will not enter this part and reflux cannot be formed. Therefore, the dust in this part will not be sucked upward. In the above process, the air passes through the filter screen 6 and enters the interior of the dustproof shell 2.

[0050] However, during the above process, a small amount of dust will still be sucked onto the filter 6. With long-term accumulation, the ventilation effect will inevitably be affected. At this time, the knob can be turned when the cooling fan 17 stops working to rotate the screw 12, and then the slider 14 drives the brush 15 to move along the axial direction of the slide rod 13, thereby cleaning the filter 6 to make the dust fall off and fall into the dust collecting bin 9.

[0051] By rotating the internal threaded sleeve 11, the connection between the internal threaded sleeve 11 and the second docking ring 10 is released, and the dust collecting barrel 9 can be removed. After cleaning, the second docking ring 10 is fitted with the first docking ring 8, and the internal threaded sleeve 11 is rotated again to connect the second docking ring 10 with the internal threaded sleeve 11, and the installation of the dust collecting barrel 9 is completed.

[0052] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
