Cooling system of outdoor cabinet using underground heat pipe

Currently the energy-saving strategy is one of the top priorities of Telecom Operators and Governments. In particular, the area of cooling has a heavy impact on the total electrical energy consumption, and needs to be optimized in order to increase overall performances, reducing both CAPEX/OPEX and the environmental impact. The present paper describes a new cooling solution for FTTC outdoor cabinets (where a significantly high amount of heat needs to be dissipated). This solution is based on geothermal cooling technique, that takes advantage of the ground heat (in this case “cold”) source, which is always available and has an enormous potential.
