The rise of electronic devices over the last two decades has changed our way of life. Electronic product manufacturers are constantly competing with each other to produce the very best products. Often the limiting factor of an electronic device performance is its ability to dissipate heat. The faster the device cools itself, the better it will perform. Therefore the industry is in constant search of improving this area of technology i.e. electronic cooling.
This course will cover all the information you need to know for designing electronics systems that are thermally balanced.
A basic search on any job website reveals many high paying jobs in this sector. No doubt with electronic devices becoming ubiquitous in the last two decades and the need of high performance products, the skill for electronics cooling is very much in demand. Jobs in this sector are lucrative. This course aims to equip students with this much needed skill.
The skills learnt in this course are very much transferable to other areas such as Civil Engineering or Mechanical Engineering. The same concepts that are used in electronics cooling can be applied to find the heat loss by house walls or to find out the heat lost by a car engine.
This course will be beneficial for anyone looking to pursue a career as a thermal analyst.
Thermal Management of electronics is a skill in great demand.
How the course is structured ?
The lectures in the course have been delivered through whiteboard animations. This techniques breaks-down complex ideas into easy to digest, bite size concepts. Whiteboard animations have also proven to enhance student experience.
The course begins with how heat is generated. It later deals with how heat is dissipated. There are also calculations in the course that are explained step by step. Through these calculations student will become confident in assessing electronics components through their datasheets.
A section of the course has been dedicated to best techniques in the industry for electronics cooling. Heat Sinks, Heat Pipes, Heat Pads and Thermal Compounds have been explored. Transcripts for lectures have also been made available.
Who should take this course?
This course is for all levels and can be completed by anyone with basic knowledge of science. You should also have the ability to calculations of simple equations.
The content tries to remain focused on more practical considerations rather than delving into more academic details.
Who is the target audience?
In this brief lecture, the course and it content have been introduced. The course structure has also been described.
In this lecture the question why electronic cooling is important? has been answered.
The performance, reliability and longevity of any electronics device is closely tied to its temperature.
This lecture looks at some basics terms for electronic cooling that need to be learned before proceeding further in the course.
Heat transfer in electronic systems occurs at multiple level. Right down from the die to casing heat transfer and all the way up to server room cooling. At each level different solutions are required.
Almost all heating in electronics happens because of internal circuit resistance. This is called Joule Heating. In this lecture, Joule heating has been explained along with its calculation
This lecture looks at the three modes of heat transfer namely conduction, convection and radiation. Please note that a complete course on Heat Transfer is available free on Udemy by the name of "Introduction to Heat Transfer".
In this lecture "Thermal Resistance" has been explained. It has also been described how heat flow is analogous to flow of water.
In this lecture, the heat sink and its functionality has been thoroughly explained. Heat sink use both in case of natural and forced convection have been covered.
In this lecture, how the "thermal curves" for heat sink should be interpreted, has been explained.
This lecture breaks down the calculation of thermal resistance. Please also see the accompanying notes and exercise to benefit from this lecture.
Heat pipes are exciting new devices that shift heat. This lecture explores how they can be used even in small electronic devices.
Heat sink compounds are important for reducing interface resistance. This lecture looks at the uses and types of thermal compounds available in the market.
It also looks at thermal pads/foam and also touches on the tightening torque
Graphite is a material that has the highest in plane thermal conductivity. How they can be used for removing heat has been explained in this lecture.
This lecture lists the important software available in the market that are used by thermal analyst. Links to free software have also been provided
This lecture concludes all the major points covered during the Electronic Cooling course.
I graduated as a Mechanical Engineer in 2001 and since then have had a split career. I have worked both in the industry and taught in the academia. This has helped me marry the practicality of work place to the thoroughness of academic study.
I enrolled as a PhD student in 2004 (Edinburgh, UK) and completed my doctorate in 2007 in Renewable Energy (Solar Thermal)
Since then I have in my spare time conducted numerous workshops on Renewable Energy and have been an instructor for Engineers without Borders. I have taught budding Engineers both at college and University. I am a published author of two books.
Teaching is my passion alongside solving engineering challenges that can make a difference to humanity
