Description

Technical Field

[0001] The utility model belongs to the field of electric control box equipment, in particular to an integrated waterproof electric control box. Background Art

[0002] The nine-fold profile is formed by bending the cold-rolled steel plate nine times with precision to form a high-strength column-beam structure. After being welded into a frame, this structure is combined with other components such as sheet metal panels to assemble into a complete electric control box. In order to achieve the waterproof function, this type of box is usually designed with a complex ceiling structure on the top. Although it can effectively prevent water penetration, such a design makes the structure complicated and involves a large number of parts, resulting in a relatively high overall cost. In the electrical design of air-conditioning equipment, especially when dealing with large variable-frequency air-conditioning equipment, it is common to place the strong and weak current systems in separate electric control boxes. Although this independent arrangement can separate electrical interference to a certain extent, it also leads to an increase in cost. More importantly, this layout makes the internal wiring extremely complicated and messy, which not only brings difficulties to the installation work, but also greatly increases the difficulty and cost of daily maintenance.
