In summer months cyclist beverages warm up to undesirable temperatures. This discourages riders from staying hydrated. It is important to stay hydrated while performing physically demanding activities. Our product the H2Cool aims to cool a beverage bottle while riding thus encouraging the rider to drink more during a long bike ride.
The most important design requirement is to cool the bottle to between 40°F and 70°F. The H2Cool will be affordable to the average cyclist while also lasting a long time through daily wear and tear. Being able to mount to any standard bicycle frame is part of our design criteria. Last but being the most important is H2Cool will be safe to use and operate.
Proof of Concept
Our product, the H2Cool, is designed for the cycling industry. With the general population being more health-conscious cycling has become a huge industry. It is an easy way for people to get cardio while being low impact on joints. Our team has searched for similar products and all the current products will not cool a water bottle for extended rides. Most products will only cool for a max of two hours or are only designed to insulate already cooled water. Our biggest competitor is going to be insulated bottles. In particular the CamelBak Podium Chill bottle, this bottle is widely popular and has a lost cost of around $15. Consumers purchase many items like the H2Cool through large online retailers. The cycling community really prides itself on buying through local bike shops, just in the Reno/Sparks area there are more than 10 locally owned bike shops.
In order to be sure that the basic cooling functions of H2Cool are able to perform to design requirements, Team 10 will design and conduct a proof of concept test. This PoC will test the cooling ability of a peltier cooler. Team 10 designed a specific PoC to test the efficiency of peltier cooler in conjunction with heat sinks and fans to find out how well the entire system can cool 300ml of 70°F water in a beaker. The peltier cooler will be tested with a 7.4V and 11.1V LiPo battery.
The H2Cool is a bottle cage with a built-in cooling system that will keep a bicyclist’s bottled beverage at a desirable temperature for consumption so that the bicyclist stays hydrated and safe.
H2Cool’s design is based around a 40mm square peltier cooler. The peltier cooler is placed on the bottom of a ⅛” thick copper cup, made to fit a standard water bottle, in order to cool the copper and thus the water bottle inside. The copper cup is surrounded by a ⅜” layer of neoprene for insulation. The neoprene will also provide protection to the copper cup with its high wear resistance to outside elements such as weather and debris. A heatsink and fan are placed on the bottom of the peltier cooler to dissipate the large amount of electrical heat the peltier creates. The peltier cooler and fan setup is powered by a LiPo battery.
The team started on the plasma cutter by cutting out the blanks for the rear support and cup. The cup was then rolled into a cylinder and welded along the seam and the base was welded to the bottom on the cylinder. A manual mill was used to drill and tap mounting holes in the aluminum base plate and copper cup. A manual mill was also used to mill out the pocket in the aluminum base plate for the TEC. The neoprene insulation was cut to size and attached to the outside of the copper cup. A fabric outer layer was sewn to be a snug fit over the neoprene insulation. All parts were then assembled into the final prototype.

Meet the Team
Chad is a graduating senior at the University of Nevada, Reno studying Mechanical Engineering. He grew up in Reno and attended Reno High School. Prior to attending UNR Chad worked as a CNC machinist for 9 years at Gyford Productions. He interned at Haws corporation where he worked with portable eye wash stations and a new module outdoor drinking fountain system. There he had to quickly learn CSA and NSF regulations regarding drinking water and safety systems. Chad is a past president of the Human Powered Vehicle Team and has been a member for 3 years. After graduation Chad will pursue a career as a manufacturing engineer in the Reno area.
After serving his enlistment in the United States Air Force, Joshua realized he needed a civilian skill set. Many of Joshua’s military skills as a Team Leader, Operations Supervisor, electrical systems testing, and mechanical systems repair, seemed a natural choice to pursue a degree in engineering. He enrolled into Truckee Meadows Community College to complete an Associates of Science and graduated with honors as a Phi Theta Kappa member. He immediately transferred into the University of Nevada, Reno to complete a Bachelors of Mechanical Engineering. Joshua is originally from Sacramento, CA. After graduation, Joshua plans to complete several internships as a machinist, CAD drafter, and structural mechanics and dynamics engineer to build a strong skill set background.
Haley was born in Las Vegas, NV and moved to Florida and Colorado before finally residing in Reno, NV. She wanted to be a mechanical engineer after working at the Henderson Executive airport and falling in love with the detailed craftsmanship of avionics parts. Her goal is to eventually get her private pilot’s license and work as an engineer in the aerospace industry, melding her hobby with her career. Until then, Haley’s goal is to take her engineering technical electives that will further define and specialize her engineering skills and graduate on time, in the spring of 2019.
During her academic career, a couple of classes have made a big impact on her development. Computer aided design and manufacturing allowed her to get certified in SolidWorks and built her own 3D printer that she is now able to use as a hobby. Since bringing home her 3D printer, she had modified it, such as putting on a better print bed. Her most challenging engineering project at the University of Nevada, Reno (UNR) was the K-12 STEM outreach project from the class Engineering Communications. Her team had to create a lesson plan to teach a 3rd grade class buoyancy through a hands-on activity. There were many challenges to overcome, the main one being communications. Not only was communication among the team challenging, but communication with children who have minimal to no prior knowledge of an advanced subject was the biggest objective.
Outside of engineering, Haley has been apart of two organizations: The Engineering College Council and Alpha Kappa Psi. Haley was the Engineering Career Fair Director at Colorado State University for 2 years before she transferred to UNR. Since then, she has joined a business fraternity and is currently the professional chair.
Amanda was born and raised in Reno, Nevada and attended A.C.E., a technical career high school, where her education and passion for drafting and design began with AutoCAD. Her knowledge has expanded to many CAD programs including: SolidWorks, Inventor, and Revit. During her college career, she dove deeper into the use of SolidWorks, performing finite element analysis of parts and assemblies. She became a Certified SolidWorks Associate in the Fall of 2018, and also began the hands on machining aspect of engineering which is her direction of focus in career opportunities.
Current Draftsman at McGinley & Associates Environmental Engineering and Science of Reno, Nevada. Previous work experience in the automotive collision repair industry, Concours Body Shop of Reno, Nevada. Outside of her schooling, Amanda has been a volunteer photographer for 4-wheeling events including Toyota Land Cruiser Association’s Annual Rubithon and Marlin Crawler’s Annual Round-Up both held on the Rubicon Trail. Her photography has been featured in the Toyota Trails magazine. Amanda will graduate in the Spring of 2019 with her Bachelor of Science in Mechanical Engineering and a minor in Business Administration. She will pursue a career in the manufacturing industry.
Some of Alex’s academic accomplishments are completing various engineering courses at the University of Nevada, Reno as well as receiving his CSWA (Certified SOLIDWORKS Associate). The most challenging engineering project he has worked on is when he spent the summer at Turbohoses Motorsport, which is a company that specializes in Noble and Lotus sports cars. While there Alex assisted in fabricating and the building intricate turbo parts for Noble engines. Some of his accomplishments outside of school include his work with Turbohoses Motorsport, where he applied his engineering knowledge in a hands on environment. Alex is from Danville, California and his main goal right now is to graduate from the University of Nevada, Reno with a BS in Mechanical Engineering. His goals after graduation are to move to San Diego and find an engineering job for a while, and then eventually move back to the Bay Area and find a job at a tech company in Silicon Valley.
