[0031] like Figure 1 , Figure 2 and Figure 4As shown, an embodiment of the present invention provides a passive heat dissipation device for a metal coil controller, comprising a bottom support plate 1, a controller housing 2 is fixedly connected to the top of the bottom support plate 1, support frames 3 are fixedly connected to both sides of the top of the bottom support plate 1, a plurality of heat dissipation fans 11 are evenly fixedly connected to the outer inner part of the support frame 3, the inner sides of the support frames 3 are connected to the sides of the controller housing 2 through limiting wind shields to increase the wind force of the flow entering the controller housing 2, a plurality of heat dissipation fins 9 are fixedly connected to the front and rear sides of the controller housing 2 to discharge the internal air in multiple directions, a working chip 20 is fixedly connected to the middle of the top of the bottom support plate 1, a conductive silicone pad 21 is coated on the top of the working chip 20, and the top of the conductive silicone pad 21 is pressed and fixed by a conductive copper sheet 22, the limiting wind shield comprises an air induced draft shield 10 located on both sides of the controller housing 2, a linear enlargement plate 16 is fixedly connected to the inside of the air induced draft shield 10, a plurality of enlargement ports 17 are evenly opened inside the linear enlargement plate 16, and a top dustproof plate 12 is magnetically attracted to the middle of the top of the controller housing 2;
[0032] Through multiple cooling fans 11, external air is simultaneously drawn into the interior of the hood 10, and the air flows through multiple enlarged openings 17 of the linear enlarged plate 16 inside the hood 10. Because the interior of the hood 10 is trapezoidally inclined, the air flows are gathered and passed through. When passing through the enlarged openings 17, the wind force is squeezed, thereby further increasing the wind force of the air entering the controller housing 2. The air convection collision on both sides evenly dissipates the heat for the working chip 20 in the middle. With the entry of wind force, the hot air generated by contacting the working chip 20 is discharged outwardly toward the cooling fins 9 and the top dustproof plate 12 along with the wind pressure, thereby improving the heat dissipation efficiency, improving the air duct inside the controller, cooling the internal chips through convection wind, and discharging hot air in multiple directions, thereby improving the cooling effect.

At this time, the hood 10 is pulled outward through the handle at the front end of the hood 10. The outer side of the side dustproof plate 15 is slightly convex outward, and the cleaning soft glue 18 contacts the outer side of the side dustproof plate 15, thereby cleaning the dust accumulated on the outside of the side dustproof plate 15, and the hood 10 is removed and cleaned to ensure the effectiveness of heat dissipation, ensure the long-term heat dissipation effect of the device, and improve the stability of the heat dissipation of the device.
