Design and implementation of a portable heat exchanger kit in an undergraduate engineering heat and mass transfer course
A compact and cost-effective heat exchanger kit was successfully designed, built, and implemented in an undergraduate pharmaceutical engineering course on heat and mass transfer. The kit consists of a control box (dimensions: 160 mm x 180 mm x 98 mm) and a plate heat exchanger measuring 120 mm x 180 mm, along with various accessories. By utilizing affordable electronics and mechanical components, we were able to create 25 kits (cost: ~USD$320/kit) that facilitate immersive hands-on learning experiences. In this study, the heat exchanger kit was incorporated into laboratory sessions. After the end of the sessions, a student survey was administered to gather feedback from all 71 participants. Students’ perceptions towards the kit in aiding their understanding of heat transfer principles was assessed. The survey results clearly indicated that the practical engagement with the heat exchanger kit had a positive influence on the students' comprehension and visualization of how heat exchanger systems work. Students recognized its representation of an industrial heat exchanger operation and its efficacy in enhancing their understanding and visualization of heat exchangers. By considering the encouraging outcomes and the positive feedback obtained from the students, we are motivated to continue utilizing the heat exchanger kit for future cohorts.
