Therefore, the power consumption of the entire chassis is also continuously increasing, while the expected size of the entire chassis remains unchanged or becomes more compact, which poses higher requirements for the overall machine heat dissipation technology and reliability. The performance requirements for the backend control chassis equipment are getting higher and higher. The chassis needs to have a high degree of integration and reliability, and realize long-term stable and reliable comprehensive system control functions in an extremely compact space to ensure the long-term high-performance stable operation of front-end radiation-resistant cameras and other devices.
