As the control center of numerical control machine tool, PLC control cabinet is responsible for centralized management and control of various electrical components and functional modules of machine tool, and ensures that machine tool runs accurately according to preset program.

This mode is very low in efficiency, and it is difficult to cope with the increasing heat dissipation demand, so that the temperature in control cabinet rises rapidly, and the normal performance and service life of electrical components are affected. For example, when the ambient temperature is high, the temperature in control cabinet may exceed the tolerance range of electrical components, so that the components fail, such as chip performance degradation, solder joint disbonding, etc. The simple fan heat dissipation scheme introduced subsequently improves the heat dissipation effect to some extent, but still has obvious defects. Ordinary fan is usually single air direction and fixed speed, and it is difficult to fully and uniformly dissipate heat in the complex thermal field in control cabinet. The temperature difference in different areas of control cabinet is large, and the area where some key electrical components are located may be in high temperature state for a long time due to insufficient heat dissipation, which affects the stability and reliability of equipment.
