Abstract

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.

本科工程传热传质课程中便携式换热器套件的设计与实现

成功设计、制造了一种紧凑且具有成本效益的热交换器套件，并在一门关于传热和传质的本科制药工程课程中实施。该套件包括一个控制箱（尺寸：160 mm x 180 mm x 98 mm）和一个尺寸为120 mm x 180毫米的板式换热器，以及各种附件。通过利用价格合理的电子和机械部件，我们能够创建25个工具包（成本：320美元/工具包），促进身临其境的动手学习体验。在这项研究中，热交换器套件被纳入实验室会议。课程结束后，进行了一项学生调查，以收集所有71名参与者的反馈。评估了学生对该工具包的看法，以帮助他们理解传热原理。调查结果清楚地表明，热交换器套件的实际使用对学生理解和可视化热交换器系统的工作方式有积极影响。学生们认识到它对工业换热器操作的代表性，以及它在增强他们对换热器的理解和可视化方面的功效。考虑到令人鼓舞的结果和从学生那里获得的积极反馈，我们有动力在未来的队列中继续使用热交换器套件。

期刊介绍： Education for Chemical Engineers was launched in 2006 with a remit to publisheducation research papers, resource reviews and teaching and learning notes. ECE is targeted at chemical engineering academics and educators, discussing the ongoingchanges and development in chemical engineering education. This international title publishes papers from around the world, creating a global network of chemical engineering academics. Papers demonstrating how educational research results can be applied to chemical engineering education are particularly welcome, as are the accounts of research work that brings new perspectives to established principles, highlighting unsolved problems or indicating direction for future research relevant to chemical engineering education. Core topic areas: -Assessment- Accreditation- Curriculum development and transformation- Design- Diversity- Distance education-- E-learning Entrepreneurship programs- Industry-academic linkages- Benchmarking- Lifelong learning- Multidisciplinary programs- Outreach from kindergarten to high school programs- Student recruitment and retention and transition programs- New technology- Problem-based learning- Social responsibility and professionalism- Teamwork- Web-based learning
