In this way, the heat in the electromechanical equipment cannot be dissipated in time, so that the electromechanical equipment is in a heating state for a long time. In the long run, it will cause internal failure of the electromechanical equipment, greatly affecting the work efficiency. With the development of science and technology, electromechanical protection devices have gradually appeared in the market. However, the closed shell is used for active heat dissipation, and the closed environment may limit the fin area and air convection efficiency. SUMMARY

A semi-closed shell is used, and air flows through the inner wall of the shell instead of directly blowing air onto the internal equipment, reducing dust entering the internal equipment, improving the protection level, avoiding direct airflow blowing sensitive elements, preventing physical damage or temperature impact, mainly cleaning the outside of the shell and the heat dissipation channel, and not needing to frequently open the equipment, making maintenance more convenient.
