[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] In the embodiment, Figure 1-5 A wind-cooled heat dissipation structure for a controller housing is provided. The utility model includes a controller housing 1, a plurality of first threaded holes are opened inside the controller housing 1, a first bolt 2 is threadedly connected to the inside of the plurality of first threaded holes, and the plurality of first bolts 2 are threadedly connected to the mounting plate 3. The outer side of the mounting plate 3 is fixedly connected to a protective cover 4 by fasteners, a fan rib 5 is provided on the outer side of the protective cover 4, a cooling fan 6 is provided inside the protective cover 4, a second bolt 7 is provided inside the fan rib 5 that passes through the protective cover 4 and is threadedly connected to the cooling fan 6, the rear side of the mounting plate 3 is fixedly connected to a heat conducting plate 8 located inside the protective cover 4 by fasteners, and a plurality of heat sinks 9 are fixedly connected to the outer side of the heat conducting plate 8.

[0029] There are two cooling fans 6 symmetrically distributed in the upper and lower parts. The interiors of the heat sinks 9 are provided with clearance grooves. The two cooling fans 6 extend into the clearance grooves and do not contact the heat sinks 9 .

[0030] In this embodiment, during actual use, two cooling fans 6 are started at different positions to blow the inside of the protective cover 4. The cooling fans 6 maintain a certain distance from the heat sink 9 to increase the heat dissipation area of ​​the cooling fans 6 while preventing the heat sink 9 from blocking the blowing surface of the cooling fans 6.

[0031] The plurality of heat sinks 9 are vertically distributed, the protective cover 4 is U-shaped, and the upper and lower sides of the protective cover 4 are hollowed out.

[0032] In this embodiment, during actual use, when the cooling fan 6 blows the heat sink 9, air is introduced into the protective cover 4 from the outside under the action of the cooling fan 6, and since the heat sink 9 is vertically arranged, under the shielding of the heat sink 9, the outside air will spread up and down along the position of the heat sink 9, and under the restriction of the outer protective cover 4, the air flow driven by the cooling fan 6 will be discharged from the upper and lower sides of the protective cover 4 to form a complete air path, which is convenient for the heat dissipation of the heat sink 9.

[0033] Among them, there are six countersunk holes in the interior of the heat conducting plate 8 and they are symmetrically distributed in a pattern of three by three on the left and right. The interiors of the six countersunk holes are all threadedly connected with third bolts 10 that penetrate and extend into the interior of the mounting plate 3 and are threadedly connected to the mounting plate 3.

[0034] In this embodiment, during actual use, the heat conducting plate 8 can remain fixed to the mounting plate 3 under the action of the third bolt 10. The purpose of setting the countersunk hole is mainly to prevent the third bolt 10 from blocking the exhaust vents from the upper and lower sides of the protective cover 4, thereby preventing it from affecting the heat dissipation performance of the device.

[0035] The left and right walls of the protective cover 4 extend outward, and the interior of the mounting plate 3 is provided with four second threaded holes symmetrical in pairs. The internal threads of the protective cover 4 are connected to fourth bolts 11 that are respectively threadedly connected to the four second threaded holes.

[0036] In this embodiment, during actual use, the main body of the protective cover 4 is U-shaped with folded edges on both sides. This structure can be achieved by bending the profile. The second threaded hole on the protective cover 4 can be used to fix the protective cover 4 to the mounting plate 3 under the action of the fourth bolt 11, which facilitates the assembly and splicing of the device.

[0037] The interior of the mounting plate 3 is provided with four mounting holes that are symmetrical in pairs. The distance between the two mounting holes is greater than the width of the protective cover 4 .

[0038] In this embodiment, during actual use, the mounting hole is used to fix the mounting plate 3. When the mounting plate 3 is installed, the protective cover 4 will not block the mounting hole. After the installation is completed, the protective cover 4 maintains a certain distance from the wall or box body to prevent affecting the operation of the cooling fan 6.

[0039] Working principle:

[0040] First, the device can be assembled. The controller housing 1 can be installed on the mounting plate 3 under the action of the first bolt 2. Then, the heat conducting plate 8 can be connected to the mounting plate 3 through the third bolt 10. The cooling fan 6 and the fan rib 5 are placed on both sides of the protective cover 4 respectively. The cooling fan 6 is fixed to the protective cover 4 by aligning the second bolt 7 with its hole position. The fan rib 5 is a reinforcing rib structure on the fan blade, which helps to reduce the vibration of the fan blade when the fan blade rotates at high speed and improve the overall stability. Then, the assembled protective cover 4 is fixed to the mounting plate through the fourth bolt 11. 3, thereby completing the air-cooling heat dissipation structure on the controller housing 1. When the controller housing 1 is running and heating up, the heat conducting plate 8 can distribute the temperature of the controller housing 1, and the multiple heat sinks 9 can increase its heat dissipation area, so that the heat distributed to the controller housing 1 can be dissipated faster. When the heat dissipation fan 6 is started, the outside air will be introduced to blow on the heat sink 9, accelerating the heat dissipation of the heat sink 9. The hot air blown away will be discharged from both sides of the protective cover 4 along the direction of the heat sink 9 to complete a complete air duct circuit, thereby accelerating the heat dissipation efficiency of the controller housing 1.
