This invention provides a pile cooling system which can reduce the number of the components, low the manufacturing cost and save the installing space. Said pile includes high pressure conductive route (acting as cooling component) that is connected with the pile anode and the cathode respectively. Said high pressure conductive routes that are connected with the pile anode are arranged along the pile so as to absorb the heat generated from the pile and give out the absorbed het at a position far away from the pile. This invention cools the pile by utilizing the excellent thermal conductivity of the high pressure conductive route.
