The indoor temperature and humidity of the outdoor intelligent control cabinet have great influence on the safe and stable operation of the intelligent electronic devices in the control cabinet. This paper first analyzes the influence of atmospheric environment factors on the components in intelligent control cabinet

then the working principle and characteristics of TEC air conditioner are introduced. On the basis of these

a new temperature control scheme of the air conditioner is proposed in order to meet the long term safety and stable operation requirements of outdoor intelligent control cabinets

in which the conditioner is divided into two parts

and adopts the linkage rotation system. Then the double TEC air conditioning control method of intelligent control cabinet is studied. The test results verify the effectiveness of TEC air conditioning outdoor control cabinet in heat dissipation and dehumidification in high temperature.
