DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the present application clearer and more apparent, the present application will be further described in detail below in conjunction with the embodiments and drawings. Herein, the illustrative embodiments of the present application and their descriptions are used to explain the present application, but not as a limitation to the present application.

[0040] Reference is made to Figures 1 to 7 , for example Figure 1 and Figure 2 ​​​​​As shown, this embodiment provides a roller shutter door motor with a heat dissipation device, including: a roller shutter door motor 2, a first heat dissipation component, several protective covers 6, and several second heat dissipation components. The heat dissipation cover 1 is installed outside the roller shutter door motor 2 and on the wall of the building. Several vertically arranged first heat dissipation holes 12 are opened on the side of the heat dissipation cover 1. The first heat dissipation component is installed on the heat dissipation cover 1 and is connected to the heat dissipation cover 1. Several protective covers 6 are spaced apart on the heat dissipation cover 1. The upper and lower ends of several protective covers 6 are installed in the grooves 11 opened on the side of the heat dissipation cover 1 by first screws 62. The protective covers 6 can block and protect a vertical row of first heat dissipation holes 12. Several second heat dissipation components are arranged in a ring on the side of the heat dissipation cover 1, and the second heat dissipation components and protective covers 6 are alternately distributed.

[0041] Preferably, the protective cover 6 is provided with a protective net 61, which can shield and protect the first heat dissipation hole 12, so as to prevent foreign objects from entering the first heat dissipation hole 12 without affecting the heat dissipation of the first heat dissipation hole 12.

[0042] In this embodiment, a gear reducer 3 is provided below the heat sink 1, and the roller shutter door motor 2 extends into the gear reducer.

[0043] like Figure 2 As shown, the first heat dissipation component includes: a heat dissipation box 4, a mounting plate 44, and a heat dissipation fan 45. The heat dissipation box 4 and the heat dissipation cover 1 are connected together by bolts, making it easy to disassemble the heat dissipation box 4. The mounting plate 44 is installed inside the heat dissipation box 4. The heat dissipation fan 45 is installed on the mounting plate 44. Multiple fan blades 46 are installed at the output end of the heat dissipation fan 45. The roller shutter door motor 2 is electrically connected to the heat dissipation fan 45. When the roller shutter door motor 2 starts, the heat dissipation fan 45 also starts to work. When the roller shutter door motor 2 stops working, the heat dissipation fan 45 also stops. This ensures that the heat dissipation fan 45 can play a timely heat dissipation role when the roller shutter door motor 2 is working.

[0044] In this embodiment, the heat dissipation box 4 includes a box cover 41 and a box body 42. The box body 42 is connected to the heat dissipation cover 1 by bolts. The box cover 41 is threaded onto the box body 42 to facilitate maintenance of the parts inside the box body 42. The mounting plate 44 is installed inside the box body 42 and is located above the roller shutter door motor 2.

[0045] The mounting plate 44 has a through hole that connects the heat sink 1 and the heat sink box 4, which accelerates the air blowing from the fan blades 46 into the heat sink 1, thereby accelerating heat dissipation.

[0046] In this embodiment, a filter screen 43 is provided on the top of the housing 42. The operation of the cooling fan 45 can accelerate the replacement of air inside and outside the heat dissipation cover 1 and the heat dissipation box 4. Therefore, the filter screen 43 is provided to facilitate air flow.

[0047] The heat sink 1 has a notch 13 through which power supply lines and other wires pass.

[0048] like Figure 5 As shown, several exhaust holes 421 are provided on one inner wall of the housing 42, and the exhaust holes 421 can be blocked by the dustproof mechanism 7.

[0049] Specifically, the dustproof mechanism 7 includes: a slider 72, a compression spring 74, a dustproof plate 71, a magnetic plate 73, and an electromagnet 75. The slider 72 is slidably disposed in the groove 422 of the housing 42; the compression spring 74 is connected between the slider 72 and the groove 422; the dustproof plate 71 is fixedly connected to the slider 72; the magnetic plate 73 is disposed at the bottom of the dustproof plate 71; and the electromagnet 75 is disposed on the housing 42. When the electromagnet 75 is energized, it can attract the magnetic plate 73.

[0050] In this embodiment, the electromagnet 75 is linked with the cooling fan 45. When the cooling fan 45 is working, the electromagnet 75 is energized, and the energized electromagnet 75 generates a magnetic attraction, causing the magnetic plate 73 to be attracted and moved downward. As a result, the slider 72 drives the dustproof plate 71 to move downward, so that the compression spring 74 is squeezed and the exhaust hole 421 is exposed. Thus, the exhaust hole 421 connects the inside and outside of the housing 42, which can also accelerate the airflow and improve the heat dissipation effect.

[0051] Preferably, a sound-absorbing inner cylinder 5 is provided inside the heat dissipation cover 1. The sound-absorbing inner cylinder 5 is made of sponge material, which can play a role in noise reduction and sound absorption when the roller shutter door motor 2 is working.

[0052] like Figure 3 and Figure 4 As shown, in order not to affect the heat dissipation of the heat dissipation cover 1, a number of second heat dissipation holes 51 are provided on the inner wall of the sound-absorbing inner cylinder 5. The second heat dissipation holes 51 are connected to the corresponding first heat dissipation holes 12. This allows the hot air inside the heat dissipation cover 1 to be discharged to the outside after passing through the second heat dissipation holes 51 and the first heat dissipation holes 12 in sequence. The cold air outside can also enter the heat dissipation cover 1 after passing through the first heat dissipation holes 12 and the second heat dissipation holes 51 in sequence, thereby reducing the temperature of the roller shutter door motor 2.

[0053] like Figure 6 and Figure 7 As shown, the second heat dissipation component includes: a heat dissipation plate 8 and a plurality of heat dissipation fins 81. The heat dissipation plate 8 is installed on the outside of the heat dissipation cover 1; the plurality of heat dissipation fins 81 are arranged in parallel and opposite to each other on both sides of the heat dissipation plate 8.

[0054] Preferably, the heat sink 8 and the heat sink fins 81 are made of copper or aluminum sheets with good heat absorption effect, so that the heat sink 8 can quickly absorb the heat transferred from the roller shutter motor 2 to the heat sink 1 and then discharge it to the outside through multiple heat sink fins 81.

[0055] Working principle: when the roller shutter door motor 2 works, the cooling fan 45 and the electromagnet 75 start at the same time, the electromagnet 75 is electrified, so that the dustproof plate 71 moves down, exposes the exhaust hole 421, the cooling fan 45 drives the fan blade 46 to rotate, so that the cold air outside enters the cooling cover 1, when the cold air passes through the roller shutter door motor 2, the heat on the surface of the roller shutter door motor 2 will be taken away, so as to cool the roller shutter door motor 2, in addition, the heat generated by the roller shutter door motor 2 when working will be transmitted outward through the cooling cover 1, so that the temperature of the cooling cover 1 is higher than that of the outside, therefore, through the cooling plate 8 and the cooling fin 81, the cooling of the cooling cover 1 can be accelerated; in addition, when the cooling fan 45 works, the exhaust hole 421, the first cooling hole 12 and the second cooling hole 51 can accelerate the flow of air inside and outside the cooling cover 1, so as to accelerate the cooling process.

[0056] In summary, the present application can realize the rapid cooling of the roller shutter door motor 2, and has the characteristics of good cooling effect and high cooling efficiency.

[0057] The above only describes the preferred embodiments of the present application and is not used to limit the present application, and the embodiments of the present application can be variously changed and varied for those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
