Dylan Romig is a freshman mechanical engineering major at Drexel University. He lives in the Lehigh Valley located in eastern Pennsylvania. Dylan is a member of Drexel's Formula SAE Electric Vehicle Team and AIAA. His main interests and passions reside around aerospace and manufacturing. He hopes to take his expertise in design, fabrication and machining into the entrepreneurial manufacturing sector to work on a start-up in advanced production of aerospace vehicles and systems.  He is the lead for the mechanical design and fabrication of the heat pipe.

Man Yi (Ariel) Yeung: my442@drexel.edu

I am a freshman chemical engineering student at Drexel University. I am from Shanghai, China. I am passionate about chemical engineering because I love to apply my knowledge in science to solve problems. I am interested in a variety of chemical engineering fields, especially the pharmaceutical and energy section. I hope to learn more about chemical engineering and become a successful chemical engineer. I am the main research and developer of the project.


Jonathan Schwenk: jds447@drexel.edu

 I am a freshman chemical engineering major at Drexel University. I am from Lansdale, PA. I hope to gain useful knowledge and experience in chemical engineering while at Drexel, which can be applied in a future job, potentially one in the pharmaceutical industry. My main role in this project involves testing the constructed heat pipe.

I am a freshman chemical engineering student at Drexel University. I am from Tieling, Liaoning, China. I would like to dig for more knowledge about my major and hopefully find a
 job and live a decent life. My main role in the project would be focused on maintenance of this blog, though I will be involved in the process of building and testing the heat pipe.

Week 5: Lab

By
The team conducted some more tests on Prototype 2 as it was the best performing heat pipe constructed thus far. The test was conducted in the angled orientation as Prototype 2 hadn't been tested in that configuration yet. The results were promising as Prototype 2 exceeded expectations and transferred heat effectively throughout the test. The condenser end increased by 52 degrees over 300 seconds which was an improvement over the horizontal test conducted with Prototype 2. In both tests, the difference between the condenser temperature and the evaporator temperature was calculated and displayed on the graphs. The graph below shows the first test for Prototype 2. To verify our results the test was run a second time but for a longer period of time in order to narrow down on where the heat pipe's maximum operating temperature would be. The results are shown below. For Prototype 2, the effective temperature limit of the heat pipe can be approximated to 125 F without a hea...

Week 6: Lab

This week in lab, the team worked on some more testing and the construction of our final iteration of the heat pipe. A specially designed bushing had to be machined to accept the threads of the 1/8" NPT ball valve. This bushing was then soldered into the copper tube. Another angled test of Prototype 2 was conducted to compare the results from the previous tests. The data is shown below: The graph of this data is shown below: The fluctuation of T1(the temperature at the evaporating end) may be partially due to experimental error. Otherwise, this prototype performed as expected.

Week 7

By
This week in lab the team finished the construction of the final heat pipe design and was able to find a vacuum pump to test how a heat pipe would perform under vacuum. Unfortunately, the results were not promising as the new heat pipe did not nearly work as it was expected to. For the final heat pipe, one end is closed, while the other end is equipped with a valve, as shown below, that can be used to add working fluid and connect to the vacuum pump to create vacuum. After the air is pumped out, the heat pipe is tested with acetone and with water as working fluids. The result is not as well as expected. More experiments will be conducted on this heat pipe next week. The results of the experimentation done are shown below:
