Design and Realization of Double TEC Air Conditioning for Outdoor Intelligent Control Cabinet

Indoor temperature and humidity of the outdoor intelligent control cabinet are of great influence on the safe and stable operation of intelligent electronic devices in the control cabinet. Influence of atmospheric environment factors on components in intelligent control cabinet is analyzed in this paper, and working principle and characteristics of TEC air conditioning are introduced. On the basis of these, a new temperature control scheme of the air conditioning is proposed to meet the long-term safety and stable operation requirements of outdoor intelligent control cabinets, in which the conditioning is divided into two parts and the linkage rotation system is adopted. Moreover, double TEC air conditioning control method of intelligent control cabinet is studied. The effectiveness of TEC air conditioning outdoor control cabinet in heat dissipation and dehumidification in high temperature are verified by test results.
