[0046] Advantages of this utility model:

[0047] The outer frame 1 of the utility model has a structural shape of a square of 86cm*86cm with rounded corners, and is designed with a ventilated first heat dissipation grille 103 on all sides, which can quickly dissipate the heat inside the controller and protect the mainboard 4. The first heat dissipation grille 103 is designed to be curved, with visual beauty in appearance and can play a role in guiding and dissipating heat in structure. The first heat dissipation grilles 103 at the top and bottom are relatively positioned to allow airflow to flow smoothly; the first heat dissipation grilles 103 on the side are symmetrical along the middle surface, which can also allow airflow to flow smoothly. For the controller, comprehensive convection is achieved inside the upper and lower sides and the left and right sides.

All of these can be observed through the light-transmitting holes. The light-transmitting holes are designed to be 4 (or other numbers, such as 2, 3, 6, etc., the number is not fixed), and the aperture is ≤5mm, which can effectively reduce the light intensity, play a role in dispersing the light source, and provide users with a good visual experience.

[0050] In addition to the first heat dissipation grille 103 , a label slot 104 is also designed on the top of the outer frame 1 . A required label 8 , such as a QR code label 8 for displaying product information, can be pasted into the label slot 104 .
