IHS ESDU Heat pipes – performance of two-phase closed thermosyphons.
It is thought 810338 a two phase thermosyphon may be used to remove geothermal energy from a geothermal aquifer to supply energy at a rate of the order of 10 kW to a small scale user, such as a domestic dwelling.
In this project a two phase thermosyphon, approximately 8m long, was constructed and tested in order to examine design procedures and to find optimum operating conditions. The thermosyphon consisted of a 0. Two working fluids, water and hexane, were tested and a 60 mesh stainless steel wick was also used in the evaporator.
These results compare well with the predicted values found using a calculation procedure presented by Engineering Services Data Unit, Item No. The use of accurate operating conditions when predicting the thermosyphon performance was found to be essential.
IHS ESDU Heat pipes – properties of common small-pore wicks.
The use of a simple wick in the evaporator was found to hinder heat transfer. The limiting factor is thought to be the occurrence of film boiling in the evaporator. This was not predicted by ESDU The prediction of limits to heat transfer was not accurate and more work is needed in this area.
