A follow on from some of the recent blogs that have involved basic thermal heatsink calculation. This time around Dave takes you though the basic theory of thermal design and how heatsink calculations work. Then there are some real world temperature measurements to see how close to the theory we get. How do you read a heatsink thermal response graph? What is emissivity? It's all here in thermal design 101.
Great Video!
Dave, i just love you videos. Simple and understandable. When I studied at the university, I did not come across such interesting teachers.
Hello from Ukraine!
Good explanations, that inspired me to create EXCEL tools about this.👍👍👍
Why did you multiply it by 33%?
Woah. They totally skipped over this practical stuff in college.
how can we calculate copper area on pcb for heat transfer.. or this video shows heat sink for heat transfer if we can use copper pad (open masking) then how to calculate PAD size ..
Thanks for the great simplified explanation. The Radiation heat transfer rate is insignificant for small temperature differences. This becomes obvious with a simple calculation which boils down to the low constant of proportionality, Stephen Boltzmann constant, of 5.67E-8.
What's should be the size of heatsink (length and width) for Tda2030A Ic if 4 numbers of such Ic is to be mounted on same heatsink and each Ic is to deliver upto 10 watts power which are all powered by 12-0-12 v 3 Ampere transformer ?
hi , Could you show a little clearly in a pic where exactly you added the thermocouple to take heat sink measurement ?
this is what i am looking for sir
Best exlanation. Thank you!
Awesome!!
Thank you for posting this !!
Great vid!
you are awesome , thanks man
Excellent
Thank You very much sir
Hi dear, thank you for this video
I have to design a Power Supply for class, and this video made more for me than my teacher, thanks Dave
How should I find thermal resistance(Junction to ambient) of a resistor? Like it was not given in a datasheet that I read. Also, is that we can find the thermal resistance if I know the power rating?
Awesome video, you simplify something that seems so difficult, but should be…simple!
how does the value from a datasheet in W/mK relate to Celsius/Watt?
is this steve irwin and linus tech tips's secret lovechild? because im a fan
hi, please upload video to see gate charge measurement of mosfet on oscilloscope
Thank you for your excellent Tutorial!!
what would be the junction temperature of the Peltier module …..how to find it?
after 10 years I still think this is the best EE youtube video ever
Thanks a lot.
hey, correct me if im wrong
shouldn't we use (R{theta}JA) in parallel with all thermal resistances attached to case as heat sink ?
