Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation equipment, in particular to a heat dissipation device for a permanent magnet synchronous controller. Background Art

[0002] The permanent magnet synchronous controller is an indispensable part of the permanent magnet synchronous motor system. It achieves efficient and controllable operation of the motor by adjusting the current, frequency and other parameters of the motor system.

[0003] However, in the prior art, existing permanent magnet synchronous controllers often emit a large amount of heat when working, and the dustproof nets at the heat dissipation ports of some permanent magnet synchronous controllers will accumulate dust after a period of time, resulting in poor heat dissipation effect, thereby allowing heat to gradually accumulate inside the controller, easily causing the controller itself to burn out, resulting in a waste of resources. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art: the dust-proof nets at the heat dissipation ports of some permanent magnet synchronous controllers will accumulate dust after a period of time, resulting in poor heat dissipation effect, thereby allowing heat to gradually accumulate inside the controller, easily causing the controller itself to burn out, resulting in a waste of resources.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a permanent magnet synchronous controller heat dissipation device, comprising a controller housing, a vent is provided on the top of the controller housing, a partition is fixedly connected to the inner surface of the controller housing, and a main control board is fixedly connected to the surface of the partition, a fan is fixedly connected to the inner surface of the controller housing, a movable groove is provided in the controller housing, and the controller housing is rotatably connected to a rotating shaft at the movable groove, and the number of the rotating shafts is set to be several, gears are fixedly connected near both ends of the rotating shaft, a conveyor belt is meshed on the gear, a dustproof net is fixedly connected to one side of the conveyor belt, a small motor is fixedly connected to one of the rotating shafts, and the small motor is fixedly connected to the outer surface of the controller housing, a telescopic rod is fixedly connected to the controller housing, and the telescopic end of the telescopic rod is connected to both sides of the controller housing, and a cleaning plate is fixedly connected to one end of the telescopic rod.

[0006] As a preferred embodiment, the material used for the partition itself is aluminum nitride.

[0007] As a preferred implementation, a heat sink is fixedly connected to the edge of the partition.

[0008] As a preferred embodiment, a dust collecting part is slidably penetrated through one side of the controller housing.

[0009] As a preferred embodiment, there are several telescopic rods and cleaning plates.

[0010] Compared with the prior art, the advantages and positive effects of the utility model are:

[0011] The utility model starts a small motor at regular intervals to allow the conveyor belt to carry the dustproof net and move, thereby completing the surface replacement operation of the upper and lower ends of the dustproof net, allowing the dust-carrying part of the dustproof net to be transferred and exchanged with the part not carrying dust, effectively avoiding the situation in which the dustproof net at the ventilation opening of the controller housing causes poor heat dissipation of the entire controller housing due to dust accumulation.

[0012] After the dust screen is replaced, the dust-carrying part of the dust screen moves to the cleaning plate, and the cleaning plate is driven back and forth by the telescopic rod to achieve the effect of cleaning the surface of the dust screen, making it convenient for the next replacement operation of the dust screen.

Through the rotation of rotating shaft 6, the displacement of conveyor belt 8 is realized with the help of gear 7, so as to complete the operation of transferring and changing the surfaces of the upper and lower ends of dust-proof net 9. One side of conveyor belt 8 is fixedly connected with dust-proof net 9, and dust-proof net 9 plays a dust-proof role. One of the rotating shafts 6 is fixedly connected with a small motor 10, and the small motor 10 is fixedly connected to the outer surface of the controller housing 1. The function of the small motor 10 is to drive the rotating shaft 6 to rotate. A telescopic rod 11 is fixedly connected to the controller housing 1, and the telescopic end of the telescopic rod 11 is through-connected with the two sides of the controller housing 1. One end of the telescopic rod 11 is fixedly connected with a cleaning plate 12. With the help of the telescopic rod 11 and the cleaning plate 12, the effect of cleaning the surface of the dust-proof net 9 is achieved, which is convenient for the next surface changing operation of the dust-proof net 9.

[0022] Example 2

[0023] like Figure 1-4 As shown, the material used for the partition 2 itself is aluminum nitride, which is a material with electrical insulation and high thermal conductivity, and can help the main control board 3 to dissipate heat well. A heat sink 4 is fixedly connected to the edge of the partition 2. The setting of the heat sink 4 further improves the overall heat dissipation efficiency of the device. A dust storage part 13 is slidably penetrated on one side of the controller housing 1.

At this time, the gear 7 and the conveyor belt 8 are also driven by the rotating shaft 6 to move, and the movement of the conveyor belt 8 will drive the dustproof net 9 to move, so that the dust-containing part of the dustproof net 9 located at the vent of the controller housing 1 is transferred to the cleaning plate 12, and the clean part of the dustproof net 9 is also transferred to the vent of the controller housing 1. In this way, the heat dissipation effect of the partition 2, the heat sink 4, and the fan 5 on the main control board 3 is not delayed, so that the heat can be discharged to the outside of the controller housing 1 in time.
