| Comment |
A single-phase thermosyphon usually consists of a sealed tube, with a small radiator above the ground surface, containing a fluid (liquid or gas) which does not change phase. These devices have no moving parts, and they require no external power for operation. During the winter, heat from the soil surrounding the embedded portion of the pipe is absorbed by and thus warms the working fluid, which rises to the above- ground radiator section of the pipe exposed to the cooler air and loses its heat by conduction and natural convection.
