Geothermal Probe With Heat Pipe Principle
In near-surface geothermal energy generation the thermal energy stored under the EarthÃ¢â¢s surface is used for heating purposes.
It demonstrates the operation of a geothermal probe with heat pipe principle. The transparent experimental set-up provides an insight into the closed circuit of the heat transfer: it allows a clear view on the evaporation in the heat pipe, the condensation in the probe head and the reflux of the heat transfer medium on the inside wall of the heat pipe. The set-up also allows to take a closer look at the basic methods applied for determining the thermal conductivity of the surrounding soil of the geothermal probe.
