Tindak lanjut dari beberapa blog terbaru yang melibatkan perhitungan heatsink termal dasar. Kali ini Dave membawa Anda melalui teori dasar desain termal dan bagaimana perhitungan heatsink bekerja. Lalu ada beberapa pengukuran suhu dunia nyata untuk melihat seberapa dekat dengan teori yang kita dapatkan. Bagaimana Anda membaca grafik respons termal heatsink? Apa itu emisivitas? Semuanya ada di sini dalam desain termal 101. .

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
You made a mistake at 16:30. You took the wrong curve / graph. It is 10W, and 26 deg C, on the left scale. So 2.6 deg C/W. Very close to the nominal 2.70 deg C/W. The slope of this curve (starting at 0 W, 0 deg C) is the thermal resistance.
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 ?
I never understand him.
Great video Dave. Very informative and practical. A great enhancement in anticipated future designs.
Tell me someone and DONT LIE TO ME.. This guy is SPOK.. or?? ( Ya this Mr.Spok is werry good electro-magician.. good job EEV!)
but do they paint the heatsink black? is it another type of material than Alimunium for example?
