91298 - Laboratory of Measurements for Electronics Cooling Applications M

Learning outcomes

At the end of the course the student masters the techniques for diagnosing and documenting thermal management problems in electrical equipment. Direct laboratory experimentation is used as a complement to analysis in the design of thermal management solutions. The Laboratory is focused to air-cooled systems as this encompasses the widest range of electrical equipment and it allows us to deal with a manageable number of topics. The course involves lectures and laboratory experience, with a strong emphasis given to hands-on activity in the lab. Students who take this course will gain direct experience with sensors for temperature, pressure, and flow measurements. The second part of the Laboratory will be devoted to experiments on systems experiencing conduction, forced convection, free convection, and radiation heat transfer. The students will make measurements on system components such as fins, inlet grills, fans, mock-up systems useful in the prototype design phase, test and diagnose techniques for existing electronic and electrical equipment with thermal management problems.

Course contents

The Arduino system and other microcontrollers, C++ programming basics, use of various types of analog and digital sensors and their calibration, serial communication and other protocols, use of active and passive cooling systems, use of a graphic display.

Lecture notes provided by the teacher

Teaching methods

Each topic is explained both teoretically and experimentally. A series of specific laboratory experiences are foreseen.

Assessment methods

Students will be assigned laboratory projects on which they will be required to produce reports. The exam consists of an oral test on the topics covered in the course and a discussion of the solutions proposed by the student for the specific topic assigned.

Students with learning disorders and/or temporary or permanent disabilities: please, contact the office responsible ( https://site.unibo.it/studenti-con-disabilita-e-dsa/en/for-students ) as soon as possible so that they can propose acceptable adjustments. The request for adaptation must be submitted in advance (15 days before the exam date) to the lecturer, who will assess the appropriateness of the adjustments, taking into account the teaching objectives.

Teaching tools

Lessons are based on didactical material available on IOL.

Slides (powerpoint) and blackboard are used. The didactical laboratory of Fisica Tecnica will be used during the course.
