Education cycleSecond cycle
Academic level (A-D)D
Main field of studyMechanical Engineering
Grading scaleA, B, C, D, E, FX, F
At present this course is not scheduled to be offered.
Intended learning outcomes
The aim of the course is to give knowledge concerning cooling problems in electric and electronic systems, as well as knowledge about methods for thermal design of such systems.
After this course the student should be able to:
- describe, and assess cooling problems in electric and electronic systems
- perform thermal design work using methods such as:
– compact models of electronic components
– the air efficiency method for selection of fans
– the thermal territory method
- design heat sinks, and assess the impact of flow bypass
- describe and apply different compact models for characterization of components
- describe different liquid cooling techniques and assess their capability and applicability
- assess the capability and applicability of different commercial calculation tools.
Course main content
A brief repetition of the basics of refrigeration. Characterization of electronic components. The cooling efficiency concept, the air efficiency method for choice of fans. The thermal territory method for placing of components on circuit boards. Optimization of fin distances. Design of heat sinks in open geometries. Approximation of contact resistances. Liquid cooling in one-phase and two-phase. Orientation about commercial calculation tools (FEM- and CFD-programmes).
