This paper introduces an ongoing research on geothermal cooling solution (GCS) for outdoor cabinets that are used to contain telecom equipment such as FTTX network, mobile network and etc. The principle of GCS is that the heat generated inside cabinet from telecom facilities is transferred to water by an air-water heat exchanger, and then water dissipates the heat to shallow underground soil by water-soil heat exchanger. A prototype of this GCS is built and tested in Shenzhen, China. Test result shows that the prototype meets the cooling requirement with at least 3 times cooling efficiency higher than that of traditional cooling solution. It is conclude that GCS is effective and valuable for practical application, and need further more investigation.
