Outdoor base station of high temperature resistant double system cabinet air conditioner with the acceleration of the industrialization process and equipment to improve the degree of automation, such as servo amplifier, PLC converter, such as precision, complex electronic, electrical equipment is used more and more widely. These devices work will generate a lot of heat, and its high temperature is more sensitive, control cabinet long-term temperature higher than 40 ℃, will affect the stability and lifetime control equipment.

The usual solution is to install the fan for cooling in the control cabinet, but the fan work, outside dust, oil and gas will also enter the control cabinet, the surface electrostatic circuit adsorption, days and months multiplying, corrosion will cause the patch element and the printed circuit, while the impact of diffusion. Also accumulated dust damp after causing short circuit board of high-voltage part. Control cabinet work longer, the problem is more prominent, accumulated to a certain extent will suddenly failure caused the control part of the. Cabinet air conditioner (control cabinet air conditioner) is through the refrigeration to achieve heat absorption cooling compression, so that the control cabinet in a closed condition, the control of heat and moisture transfer in cabinet air from outside the cabinet. High temperature, dust, oil, corrosive gas, not in external environment into the control cabinet, in order to solve a series of problems caused by the cooling fan. The control cabinet can be maintained in the ideal temperature 30--35 ℃, electronic, electrical equipment service life and stability has been effectively guaranteed,
