Section 4: Equipment Design Advantages
Design Advantage 1:
The variable frequency wind speed regulator is set at the rear of the housing, designed to recessed, making it less prone to accidental contact. |
2. Place the fans at the very back, two fans, positioned near the bottom. |
3. The vent hole diameter on the wind panel is reduced to approximately 2-3mm. |
4. The bottom vent holes are modified to resemble louvers, making it impossible to see the internal compressor from the outside, while the ventilation holes on the other three sides are very small. |
5. Electrical loads are isolated from each other. |
6. The case is well-filled with cushioning material, particularly around the door, ensuring minimal noise when the door is opened or closed. |
Design Advantage 2:
The mechanical performance of the door handle assembly machine should be excellent. |
2. 3 sampling holes, with a pagoda joint at the connection of the inner and outer diameters. |
3. The caster support triangle is reinforced with a 5mm thickness. |
4. The internal air circulation blades have no protruding exhaust holes; they are internally fitted with a wind ring. |
5. The box door features a double door swing-open mechanism. |
6. The electric cabinet doors use dowel pins instead of screws, and reinforced ribs are added to the door. |
7. The internal fan positioning is accurately adjusted. |
8. Color: The equipment features a computer white appearance. |
