Where could I find related literature regarding this? I am currently working on studies on heat pipe and I would like to conduct some experiments on wicked heat pipe as a part of my research.
This page seems to have a lot of detail on making and testing a specific pipe design: http://www.benchtest.com/heat_pipe1.html
Thank you for your response,but the page talks about testing of heat pipe,but my intention is to fabricate a heat pipe by myself and then test it.
If you want to do all steps yourself, the job can become quite complex.
Assuming you have selected a suitable working fluid for the application, and have decided on a container and wick material that is compatible with the working fluid, the main challenge is concerned with the wick.
The first and foremost challenge is to develop/manufacture/purchase a wick that serves the duty, i.e. it should be able to provide the entire heated surface with liquid at the maximum heat load. In practice, this means that the wick should have sufficient 'pumping capacity' (capillary force) to overvome the friction and gravitational pressure losses associated with the fluid flow in the wick. Key parameters are capillary force, permeability and wick thickness.
Next, the wick has to be in good contact with the heated surface. This is achieved my mechanical pressure, sintering or similar. Do not use soldering, as this may penetrate into the wick and block fluid passages. Note also, that all wicks tend to adsorbe volatiles, which may affect wick performance dramatically. Hence, the wick material (and HP container) should be thoroughly de-oxidized before inserting the wick. (Worst case scenario: A wick may turn hydrofobic and lose its pumping capacity altogether if not de-oxidized.)
Filling of the HP may be achieved in a number of ways. If you do not wish inert gases present (which affects the vapor condensation) you must evacuate the HP, preferrably down to
Hi Erling Naess,thank you very much for your response.Well I will go through the prescribed book and take your points in to account.For your information,I am planning to work on copper heat pipe with sintered copper wick and use water as working fluid.
