Description

Technical Field

[0001] The invention relates to the technical field of frequency converter housings, and in particular to a frequency converter housing capable of accelerating heat dissipation of a frequency converter. Background Art

[0002] The inverter is an electric power control device that uses frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's working power supply. There are a large number of electronic components in the inverter, and a large amount of electric energy continuously flows through the inverter when it is working. Therefore, the heat dissipation of the inverter is the key to the box design, especially in high-power inverters. Poor heat dissipation can easily lead to malfunctions and even fires.

[0003] In this regard, China's patent application number: CN202110641607.8, discloses a frequency converter case assembly, including a case and a base; a first groove is provided on the side wall of one side of the case, and a second groove is provided on the side wall of the other side; a group of heat dissipation holes are provided at the bottom of the first groove and the bottom of the second groove; a first annular groove is provided on the side wall of the first groove, and a first filter is rotatably connected in the first annular groove; a second filter is fixedly connected to the side wall of the second groove; a protective shell is threadedly connected to the inner wall of the first groove; a frequency converter case assembly proposed in the present invention solves the problem that the frequency converter case is generally provided with a fan for heat dissipation, but in winter, the outside temperature is low, and the inside of the frequency converter case can quickly exchange heat energy with the outside world for rapid heat dissipation. At this time, the fan is no longer needed to provide additional heat dissipation energy, but the fan will block the natural heat dissipation of the heat dissipation holes.

[0004] The inverter box uses an electric motor to drive the fan blades to rotate to blow air inside the box to accelerate heat dissipation. However, when the fan blades rotate, they also drive the cleaning brush to rotate. When the cleaning brush rotates, it will brush the dust on the first filter. The wind brought by the fan blades will blow the dust, causing the dust to adhere to the first filter again, and some of the dust will spread around, polluting the air and causing inconvenience.

[0005] Therefore, in order to solve the above problems, an inverter housing which can accelerate the heat dissipation of the inverter is proposed. Summary of the invention

[0006] The object of the present invention is to provide an inverter case that can accelerate the heat dissipation of the inverter, so as to solve the problem that the inverter case in the prior art proposed in the above background technology drives the fan blades to rotate by an electric motor to blow air inside the case to accelerate the heat dissipation, but when the fan blades rotate, they will also drive the cleaning brush to rotate. When the cleaning brush rotates, it will brush the dust on the first filter net, and the wind brought by the fan blades will blow the dust, causing the dust to adhere to the first filter net again, and some of the dust will spread around, polluting the air and causing inconvenience.

[0007] To achieve the above object, the present invention provides the following technical solution: an inverter case capable of accelerating heat dissipation of an inverter, comprising: a housing, a controller being installed on the front of the housing;

[0010] A driving structure is installed in the storage groove, and the driving structure includes a baffle, which is movably installed inside the storage groove, a through hole is opened on the surface of the baffle, a filter plate is installed on the inner left end of the through hole, a turbine is movably installed on the inner right end of the through hole through a bearing, a fixed column is integrally formed on the left side wall of the turbine, a movable column is slidably installed in the middle of the through hole, a second magnetic block is arranged at the bottom end of the movable column, and a pull rod and a second spring are fixedly connected to the top surface of the baffle;

[0011] A collecting structure is installed on the heat dissipation structure, and the collecting structure includes a mounting ring, which is movably mounted on the left wall of the mounting plate through threads, a cloth bag is movably mounted on the left end of the mounting ring through bolts, and a filling ring is slidably mounted inside the mounting ring.

[0012] Preferably, the movable groove is in a "door"-shaped structure, the movable groove is located on the upper side of the mounting groove, the upper end of the storage groove passes through the top surface of the shell, and the shield is located on the upper side of the movable groove.

[0013] Preferably, the installation cavity is aligned with the through hole in upper and lower parts, the bottom surface of the push rod is in contact with the surface of the filter screen, the top surface of the push rod is lower than the top surface of the installation plate, and the first spring is fixedly connected to the inner wall of the installation cavity.

[0014] Preferably, the first magnetic block and the second magnetic block are aligned vertically and cooperate with each other, and the output end of the motor is fixedly connected to the rotating shaft on the rotating frame.

[0015] Preferably, the baffle is located on the upper side of the mounting plate, the fixed column is movably mounted inside the upper end of the movable column, the upper end of the pull rod is exposed from the top surface of the shell, and one end of the second spring is fixedly connected to the inner wall of the storage groove.

[0016] Preferably, the inner diameter of the right end of the mounting ring is larger than the diameter of the filter screen, and the left end of the mounting ring is an arc surface.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: the inverter case of the present invention is provided with a rotatable rotating frame, which can move the cooling fan to the inside of the shell, and a detachable collecting structure is provided on the outer wall of the mounting plate. The cooling fan can blow off the dust adhered to the surface of the filter from the inside of the shell, which can prevent dust from entering the shell, and the dust can be collected by the collecting structure to improve the convenience of cleaning the filter and ensure the ventilation effect of the filter, thereby achieving an improved heat dissipation effect.

[0018] A shell, a heat dissipation structure, a driving structure and a collecting structure are provided. The motor is started, and the motor drives the rotating frame to rotate. The rotating frame rotates in the movable groove so that the rotating frame moves to the inner side of the shell. At this time, the filter screen is aligned with the heat dissipation fan on the left and right. Since the heat dissipation fan moves away from the upper end of the movable groove, the lower end of the baffle is not limited by the rotating frame. Therefore, the baffle will extend from the storage groove under the action of the second spring, and the baffle will fit the inner wall of the movable groove, so that the upper end of the inner part of the movable groove can be blocked;

[0019] Screw the mounting ring onto the left wall of the mounting plate through the thread, and then fix the cloth bag to the left end of the mounting ring through the bolts. The mounting ring can be covered on the outside of the filter. Start the cooling fan, and the hot air in the shell can be quickly blown out through the filter, so as to achieve rapid heat dissipation inside the shell. The air passes through the filter from right to left, and some dust adhering to the left wall of the filter can be blown off, so that the dust is separated from the filter and can be collected in the cloth bag on the left. When the cooling fan rotates, some air in the shell can enter the through hole, and the circulation of air on the inside of the through hole can drive the turbine to rotate, and the rotation of the turbine can drive the fixed column to rotate in a circle. The rotation of the fixed column can drive the movable column to move up and down in the baffle. When the movable column descends, it can extend from the bottom surface of the baffle and be inserted into the mounting cavity. The first The second magnetic block can be magnetically attracted to the first magnetic block at the upper end of the push rod. When the movable column is raised, the push rod can be driven to move in the installation cavity through the cooperation of the second magnetic block and the first magnetic block, and the push rod will move upward away from the filter screen, and the push rod will squeeze the first spring. Since the movable distance of the movable column is greater than the movable distance of the push rod, when the movable column moves to the uppermost end, the push rod is restricted by the installation cavity, and the second magnetic block will be separated from the first magnetic block. The push rod loses the traction of the first and second magnetic blocks, and will reset downward under the action of the first spring. The push rod will hit the top surface of the filter screen downward, which can make the filter screen vibrate, and can further shake off the dust adhered to the surface of the filter screen, and collect it in the cloth bag along with the air blown out from the shell, so that the surface of the filter screen is clean and tidy, and the ventilation and dust filtering effects of the filter screen can be guaranteed.

[0020] Unscrew the bolts, remove the cloth bag from the mounting ring, then pull the pull rod to store the baffle in the storage groove, start the motor, drive the rotating frame to move in the movable groove, and rotate the rotating frame from the inside of the shell to the outside of the shell. At this time, the cooling fan and the filter are aligned left and right, and the filling ring is pulled out from the mounting ring. The left wall of the filling ring fits the right wall of the rotating frame, which can make the space between the cooling fan and the filter relatively sealed to ensure the air circulation effect. At this time, turn on the cooling fan, and air can be blown into the shell through the filling ring, the mounting ring and the filter to achieve heat dissipation and cooling inside the shell.

A turbine 34 is movably installed at the inner right end of the through hole 32 through a bearing. A fixed column 35 is integrally formed on the left side wall of the turbine 34. A movable column 36 is slidably installed in the middle of the through hole 32. A second magnetic block 37 is arranged at the bottom end of the movable column 36. A pull rod 38 and a second spring 39 are fixedly connected to the top surface of the baffle 31.

[0039] A collecting structure 4 is installed on the heat dissipation structure 2, and the collecting structure 4 includes a mounting ring 41. The mounting ring 41 is movably mounted on the left side wall of the mounting plate 21 through a thread. A cloth bag 44 is movably mounted on the left end of the mounting ring 41 through a bolt 42. A filling ring 43 is slidably mounted inside the mounting ring 41. The rotating frame 27 can be rotated to move the heat dissipation fan 28 to the inside of the shell 1, and a detachable collecting structure 4 is set on the outer wall of the mounting plate 21. The heat dissipation fan 28 can blow off the dust adhered to the surface of the filter 23 from the inside of the shell 1, which can prevent the dust from entering the shell 1, and the dust can be collected by the collecting structure 4 to improve the convenience of cleaning the filter 23 and ensure the ventilation effect of the filter 23, thereby achieving the improvement of the heat dissipation effect.

[0040] Furthermore, the movable groove 13 is in a "door" shaped structure, the movable groove 13 is located on the upper side of the mounting groove 12, the upper end of the storage groove 14 passes through the top surface of the shell 1, the shield plate 15 is located on the upper side of the movable groove 13, and the rotating frame 27 in the movable groove 13 can move outside the upper end of the mounting plate 21 in the mounting groove 12 to adjust the position of the cooling fan 28 outside the mounting plate 21.

[0041] Furthermore, the installation cavity 22 is aligned with the through hole 32 up and down, the bottom surface of the push rod 24 is in contact with the surface of the filter screen 23, the top surface of the push rod 24 is lower than the top surface of the installation plate 21, the first spring 25 is fixedly connected to the inner wall of the installation cavity 22, the first magnetic block 26 in the installation cavity 22 can be magnetically connected to the second magnetic block 37 in the through hole 32, the movement of the push rod 24 can knock on the filter screen 23, causing the filter screen 23 to vibrate, and the first spring 25 provides power for the push rod 24 to knock on the filter screen 23.

[0042] Furthermore, the first magnetic block 26 and the second magnetic block 37 are aligned up and down and cooperate with each other. The output end of the motor 29 is fixedly connected to the rotating shaft on the rotating frame 27. The first magnetic block 26 in the mounting cavity 22 can be magnetically connected to the second magnetic block 37 in the through hole 32. The motor 29 provides power for the rotation of the rotating frame 27.

[0043] Furthermore, the baffle 31 is located on the upper side of the mounting plate 21, the fixed column 35 is movably mounted inside the upper end of the movable column 36, the upper end of the pull rod 38 is exposed from the top surface of the shell 1, and one end of the second spring 39 is fixedly connected to the inner wall of the storage groove 14. The baffle 31 can block the upper end of the movable groove 13. When the fixed column 35 rotates in a circle, it can slide in the movable column 36 to drive the lifting and lowering movement of the movable column 36. Pulling the pull rod 38 can drive the baffle 31 from the movable groove 13 to the storage groove 14, and the second spring 39 provides power for the baffle 31 to fit the inner wall of the movable groove 13.

[0044] Furthermore, the inner diameter of the right end of the mounting ring 41 is larger than the diameter of the filter 23, and the left end of the mounting ring 41 is curved, so that dust falling from the filter 23 can be collected in the cloth bag 44. After the mounting ring 41 is installed, the rotating frame 27 can be rotated to the outside of the shell 1, so that the rotating frame 27 and the mounting ring 41 are aligned left and right.

[0045] Working principle: In winter, the natural heat dissipation of the housing 1 can meet the temperature requirement. At this time, the rotating frame 27 is located on the upper side of the mounting plate 21, and the baffle 31 is stored in the storage groove 14 and tightly fits the top surface of the rotating frame 27 under the action of the second spring 39;

[0046] In summer, when the natural heat dissipation of the housing 1 cannot meet the temperature requirement, the motor 29 can be started, and the motor 29 drives the rotating frame 27 to rotate, and the rotating frame 27 rotates in the movable groove 13, so that the rotating frame 27 moves to the inner side of the housing 1. At this time, the filter 23 is aligned with the cooling fan 28. Since the cooling fan 28 is moved away from the upper end of the movable groove 13, the lower end of the baffle 31 is not limited by the rotating frame 27. Therefore, the baffle 31 will extend from the storage groove 14 under the action of the second spring 39, and the baffle 31 will fit the inner wall of the movable groove 13, and the upper end of the inner part of the movable groove 13 can be blocked;

[0047] The mounting ring 41 is screwed onto the left side wall of the mounting plate 21 through a thread, and then the cloth bag 44 is fixed to the left end of the mounting ring 41 through a bolt 42. The mounting ring 41 can be covered on the outside of the filter 23. The cooling fan 28 is started to quickly blow out the hot air in the housing 1 through the filter 23, so that the inside of the housing 1 can be quickly cooled. The air passes through the filter 23 from right to left, and part of the dust adhering to the left side wall of the filter 23 can be blown off, so that the dust is separated from the filter 23 and can be collected in the cloth bag 44 on the left.

[0048] When the cooling fan 28 rotates, part of the air in the housing 1 can enter the through hole 32, and the circulation of air inside the through hole 32 can drive the turbine 34 to rotate. The rotation of the turbine 34 can drive the fixed column 35 to rotate in a circle. The rotation of the fixed column 35 can drive the movable column 36 to move up and down in the baffle 31. When the movable column 36 descends, it can extend from the bottom surface of the baffle 31 and be inserted into the installation cavity 22. The second magnetic block 37 located at the bottom end of the movable column 36 can be magnetically attracted to the first magnetic block 26 at the upper end of the push rod 24. When the movable column 36 is raised, the second magnetic block 37 and the first magnetic block 26 can drive the push rod 24 to move in the installation cavity 22, and the push rod 24 moves upward away from the filter screen 23, and the push rod 24 moves upward away from the filter screen 23. The rod 24 squeezes the first spring 25. Since the movable distance of the movable column 36 is greater than the movable distance of the push rod 24, when the movable column 36 moves to the uppermost end, the push rod 24 is restricted by the mounting cavity 22, and the second magnetic block 37 is separated from the first magnetic block 26. The push rod 24 loses the traction of the first magnetic block 26 and the second magnetic block 37, and is reset downward under the action of the first spring 25. The push rod 24 hits the top surface of the filter 23 downward, which can make the filter 23 vibrate, and can further shake off the dust adhered to the surface of the filter 23, and collect it in the cloth bag 44 along with the air blown out from the housing 1, so that the surface of the filter 23 is clean and tidy, and the ventilation and dust filtering effect of the filter 23 can be guaranteed.

[0049] Unscrew the bolt 42, remove the cloth bag 44 from the mounting ring 41, then pull the pull rod 38 to store the baffle 31 in the storage groove 14, start the motor 29, drive the rotating frame 27 to move in the movable groove 13, and rotate the rotating frame 27 from the shell 1 to the outside of the shell 1. At this time, the cooling fan 28 is aligned with the filter 23 left and right, and the filling ring 43 is pulled out from the mounting ring 41. The left side wall of the filling ring 43 is in contact with the right side wall of the rotating frame 27, so that the space between the cooling fan 28 and the filter 23 can be relatively sealed, which can ensure the air circulation effect. At this time, turn on the cooling fan 28, and the filling ring 43, the mounting ring 41 and the filter 23 can blow air to the inside of the shell 1 to achieve heat dissipation and cooling inside the shell 1.

Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention.
