Week Five

 

       In week five our group put the design into test, first we weld the copper pipe with caps on both sides and put a little bit of water inside to determine how fast the medium evaporates. We used silicon jell to ensure tight fight of the caps.

  We measured the water to about half the length of the copper pipe. We insert our wick, a mesh copper wire, and make sure that it leaves the room for the evaporation to take place.

       Also, a bit of mathematic equation were used to determine how fast the heat will transfer from the source to the top of the heat pipe. It was important for us to learn this because heat transfer through solid unevenly. We learned that the more we minimize the time for the heat to transfer the more efficiently our heat pipe works.

 The following equation was used to determine the length of the heat pipe to be heated to gain a much fast energy transfer:

                                              

                                       

Below is the images of the testing

The picture above shows a heat pipe being testes using a dryer,  clamps, temperature reader and heat sensor

     During testing we encounter the following problems, there was a leakage between the cap and the pipe, we assumed we didn’t solder it properly. Also the temperature went up very rapidly due to the higher electrical conductivity of the copper.
