Technical Field
[0001] This utility model relates to the field of circuit boxes, specifically a modularly designed air conditioning unit control circuit box. Background Technology
[0002] Traditional air conditioning unit control circuit boxes have many problems in industrial applications: Traditional control circuit boxes often use a simple natural convection heat dissipation structure. When the electrical components inside the control box generate heat during long-term operation, it is difficult to dissipate the heat effectively, resulting in an increase in internal temperature, which affects the service life of components and system stability. In addition, traditional control boxes adopt a fixed structure design, with each functional module integrated into a single box. Utility Model Content

Side plates are fixedly connected to the bottom left and right sides of the mounting plate. There are two sets of side plates. A placement frame is fixedly connected to the inner side of the two sets of side plates. A second mounting plate is fixedly connected to the bottom of the placement frame. An inner plate is fixedly connected to the end of the second mounting plate near the inner side of the circuit box. The inner plate is fixedly connected to the inner side of the circuit box.
