AI Technical Summary

Technical Problem

In existing HVAC equipment electrical control boxes, the circuit modules are concentrated in the same cavity, resulting in severe electromagnetic interference and reducing system stability and safety.

Method used

The first and second cavities are designed independently, with the first and second circuit modules physically isolated. Electrical connection is achieved through wire grooves and wire holes, and heat dissipation is achieved by combining heat-conducting plates and heat dissipation fins to avoid electromagnetic interference and insulation failure.

Benefits of technology

It improves the system stability and safety of the electrical control box, reduces the risk of short circuits, ensures the normal operation of the circuit modules, and has excellent heat dissipation, making it easy to assemble and maintain in a modular manner.

Abstract

The application discloses an electric control box and a heating and ventilation device. The electric control box comprises a first circuit module, a second circuit module, a first box cover, a mounting plate and an electric connecting wire. The first box cover has a first cavity for placing the first circuit module and a second cavity for placing the second circuit module. The opening direction of the first cavity is opposite to that of the second cavity. An edge of the opening of the first cavity is provided with a wire passing groove. The groove wall of the wire passing groove is configured to form a wire passing hole communicating the first cavity and the second cavity. The mounting plate is arranged on the opening of the second cavity to close the second cavity. One end of the electric connecting wire is connected to the first circuit module, and the other end of the electric connecting wire extends into the second cavity through the wire passing hole and is connected to the second circuit module. The electric control box of the application places the first circuit module and the second circuit module in different cavities and is separated, thereby improving stability and safety.
