ABSTRACT:
An electromagnetic signal transmission/reception tower and accompanying base station housing sensitive electronic equipment within an environment that is thermally controlled by a system employing a plurality of coaxial-flow heat exchanging structures installed in a plurality of well bores, using thermally conductive material. Each coaxial-flow heat exchanging structure includes: a helically-extending turbulence generator arranged along the outer flow channel formed between its inner and outer tube sections, so as to create turbulence along the flow of heat exchanging fluid flowing along the outer flow channel, and thereby increasing the heat transfer through the walls of the outer tube section to the Earth.
