A multidisciplinary Capstone Senior Project: Interactive Cooling System Demonstration UnitPrecision Cooling Division of Parker Hannifin Corporation has requested the development of aneducational Interactive Cooling System (ICS). The purpose of this educational InteractiveCooling System is to demonstrate the versatility and capabilities of Parker’s Precision Coolingtwo-phase electronic-cooling technology. The two-phase cooling technology utilizes the heat ofvaporization of a refrigerant in order to absorb excessive heat, commonly generated by a highpowered electronic. The two-phase cooling technology is safer and more efficient method ofheat transfer that reduces the weight, increases power density, and costs far less than thetraditional heat sink or water cooling system.A multidisciplinary capstone senior design team consisted of three mechanical engineeringstudents and two electrical engineering students was selected to work on this project. The teamwas advised by two faculty members: one mechanical engineering and one electricalengineering. The capstone senior design project spans two semesters. In the first semester, theproblem statement is formulated and basic conceptual designs are generated and then evaluated.The best conceptual design is then selected and a complete and detailed design is generated bythe end of the first semester. In the second semester, a prototype of the finished design is built,tested and evaluated. The final report and oral presentation to faculty and students are requiredfrom all design teams at the end each semester.The ICS is composed of the following components: cold plate, condenser, fan, pump,accumulator, piping, pressure sensors, temperature sensors, flow meter, R-134A refrigerant,fiberglass shell, aluminum frame, power supply, personal computer (PC), touchscreen monitor,data acquisition system (DAQ), and control algorithm. These components were researched,analyzed, modeled and selected to achieve specific performance criteria.Precision Cooling Division of Parker Hannifin Corporation provided support to construct twoICS units. One unit is for Parker Hannifin Corporation to be used in technology trade shows todemonstrate the versatility and capabilities of Parker’s Precision Cooling two-phase electronic-cooling technology . And the other unit is for our department of engineering to demonstratethermodynamics processes and principles for our undergraduate mechanical engineeringstudents. Such an apparatus would enhance the teaching (and learning) of thermodynamics.Students would be able to apply thermodynamics principles, such as the first and second laws,learned in the classroom lectures, to real-life problems. This approach could make the learning ofthermodynamics a more pleasant experience for undergraduate mechanical engineering students.
