Home-made flexible heat pipes

   Then, it’s necessary to test the heat pipe when in use. Plug one end of the pipe by soldering a coin to it. Fill up the pipe with rated quantity of actuating medium, in this case, it is two table-spoons of distilled water. We made a fuse of thin wire but decided not to use it, it’s not necessary yet…
 

   Use a coin for the second plug as well. Drill the coin and lead out a thin tubule to the vacuum pump.

    Solder securely the both ends of the tubule: one end to the coin, the other to the compressor nipple. The pump is very small, so it will take the pump 20 minutes to finish its work…, alas, I couldn’t find anything better. Drink tea with cakes listening to the chatter of Japanese motor. During this tea-break you have a good possibility to have a discussion about the results of the modding and plan another modding.

   After the necessary quantity of air has been pumped out switch off the compressor, pinch the tubule with a clip, nip it off and solder up. If you have decided to replicate the experiment, the sealing technology is described in details by refrigerationists and air-conditioning devices mounters.
