You forgot to talked about a Very Important point. A “Black body” and how back heat sinks can be more efficient by radiating more energy in the form of heat.
Bro do some video about elecret condenser microphone and how to connect with amplifier please....
0:19. THE FAN SPINS BACKWARD!!!
It
At 1:51 that resistor is HUGE! Holy RESISTORS!
That has to be one of the smoothest ads ever done
Yeah he made the ad into a fantastic educational demonstration
Well are the links in the description affiliate links or...
I feel it like my hair fall upon my shoulder
A few more details from the simulation results:
1. In the pin heat sink design, the flow is more uniform, i.e., the entire cross section of the cavity sees a similar flow velocity. The temperature at the heat sink faces is also higher and more uniform across the block as a result of an improved heat transfer capacity.
2. Determining the pressure drop reduction across the cooling block also helps calculating the hydraulic power required and therefore the selection of a suitable pump for the job.
wouldn't a tear drop shape cooling fin lower even more the pressure?
@@RafaAelM Yes but having only one fin would reduce the surface area
It's truly exceptional when a video makes me want to watch the ad and also actually integrates itself to the ad.
Perfect.
Thank you, glad you liked

The Engineering Mindset: The thermal limit is 90°C.
Intel: Those are rookie numbers!
intel: pathetic. not even 110C
My gaming laptop runs at 60 idle lmfao and 100 during heavy games. It's just fine so I think people exaggerate on how bad high heat can be
@@triton6490 it is fine on laptop,
@@triton6490 try undervolting the cpu, going over 90 while gaming is not ideal. i undervolted my cpu and now it barely goes over 80.

This is VERY well done, incredibly useful as a global survey about electric fundamentals too.
Thank you kindly!
@@EngineeringMindset can u make a video about peilter module only short video plz
My senior year in 2018 the professor for our Thermal Fluids Design course gave a group the final project of designing the proper water cooled system for his PC (He gave full specs) he was building, simply so he did not have to do it himself. It was a genius project and it's cool a guy nearing 70 was building a water cooled PC. He also worked on ballistic missiles during his heydays and presented the unqiue design challenge of trying to cool a massive guidance computer in a vacuum. Essentially, following launch until space the computer shuts off, then resumes during targeting but since it has to last only several minutes the tiny radiative cooling setup was enough!
The quality of this video is INSANE! So much info packed into a video so good.
Wish in schools they have thought me in this manner,it's so knowledgeable vedio thanks allot great work
Glad you thought so, pleased it helped
@@EngineeringMindset I have gone through your old video of chiller and HVAC,I would like those videos to be made again with more details it will be great opportunity for auntrapraneur and I wish you all the best for your good work ♥️♥️🥰🥰🥰
Love from India ♥️♥️♥️

Sooner or later every engineer should come through this channel.
Love you work
9:08 The last thing you want when transferring heat is a thick layer of thermal paste. You want the layer to be as thin as possible to get the heat away faster. In low thermal density scenarios you can get away with a thicker thermal pad (CPU VRM), but with the CPU itself you squeeze the paste thin.
Exactly, it is desirable to have the part being cooled have a direct contact with the heat sink / water block. Because the parts are not completely flat (at a microscopic level), the thermal paste is used to fill in the gaps to get a larger contact area, rather than having microscopic pockets of air.
Agreed that's why we used this as the base design and then altered this to show just how much impact changes like this can make.
I went to an engineering college but no-one explained this to me in so much detail . Thanks Paul for this video . 👍
its good that you're sponsor actually helps and not just an annoying ad :D
Why Electronics need cooling?
Ans: Because they heat up...

Her: he is probably thinking about other girls
Him: PCs freeze when they overheat. 😞
Hope you can make a topic on server or IGBT immersion cooling, which would be a continuation on the IGBT cold plat cooling at the end of this video. Thanks.
Immersion cooling is a big topic in data centre now days but it has been widely used at large power substations where IGBT modules/inverters are immersed in dialectic liquid for cooling.
as someone who's really into computer hardware and their PCB designs, this video was really great to watch. thanks!
I really want this channel to be more successful. It presents information in such interesting and useful way. Everything is explained so well so as to provide practical solutions for real world problems.
I must say this is one of those videos that you understand in the first try, thank you so much
You guys are simply fantastic. These videos are exactly why I started donating to your channel! Your animations combine with the simplicity of explanations make this channel simply amazing! Hope you guys never change your commitment to detail and beautiful streamlined explanations of engineering processes and devices.
The animations take so long 🙈 glad you enjoy them
This is the right way of explaining electronics. Ironically he’s short of a million subscribers and those who make crap content has over couple of millions subscribers.
However, your content will be in memories for years to come unlike those crap channels.
He goes through the trouble of explaining what are resistors for in the beginning of his video then expects people to just know what IGBTs are...
I didn’t read that correctly
We don’t need to know for the purpose of this video, we just need to know it produces heat
@@Chewie-xm6tp Agree. I don't even know what are IGBTs, but what I know so far is that they produce a lot of heat, therefore they need better cooling systems so they can keep working in whatever their job is.
I think the reason why he explained transistor was only to explain where the heat in electronics comes from
We should ask the IGBT community
Heatsinks that cool especially energy-hungry components (such as CPUs or GPUs in computers) will usually have a copper core with aluminium fins. The thermal conductivity of copper is greater than that of aluminium, so it is used to distribute more heat faster to the aluminium fins. Full copper heatsinks do exist, but they are very expensive and very heavy, they're generally not worth the cost.
That was a very good animated video, wonderfully done
The videos of this channel are much more helpful, easy to understand and simple and amazing than a hours of lectures in the college where I don't understand most of what is taught
Thanks a lot! Great work!
Stay safe and hydrated 😊
:)
Best channel This should be standard in schools. Thank you for your time bub
we have a thin layer of thermal paste and we try to keep it as thin as possible, because as much as thermal paste is a good conductor of heat, Cu or Al are much better, we just use thermal paste to fill in the imperfections on the surface of the metal.
Can you pls upload a video on how all these components work together pls pls pls

Awesome, thank you!
When current passes through a transistor, they generate heat. When transistors get hot, they pass more current. Current passing through a transistor generates heat. Heat allows more current to pass through. More current passing through generates more heat. Uh oh, fire.

Hi, Paul. I know you've covered PIC valves but I would love to see a video on Differerntial Pressure Control Valves if you're taking on suggestions? Your style of videos are, by far, the most informative on RUclips. Keep up the great work.
thanks to you bro ,today finally i learned what is voltage drop and how its happing in my whole life. A Big Thank you

Perfectly explained ...immediately subscribed...✌️
We designed and built sensors using beta decay, near IR, xray , spectrophotometers and a few other camera type instruments. Dirt and temperature cause drift and need to normalized. Using milspec components helps surviveability. Water cooling requires heat exchangers and is very effective but requires expensive closed loop components. Using air works but also typically requires air dryers and filters. Wet dirty air is death. Water leaks ouch. Having a product fill with water is not good. Dripless connectors and leak tests for soldered fittings and over pressure tests might help. The most fun for source and detectors is keeping windows clean. Bernouli hold downs air knifes are just a few. Shipping inadequate designs can kill a company and careers.
Needed you in my childhood days so many questions answered thank you bro.
Im really curious about heat sink applications on firearms, specifically for cooling down barrel and outside of chamber and also for grip panels
Fantastic presentation. So much added information. Thanks.
Big ups for saying aluminium and aluminum instead of complaining about the difference like everyone else on youtube
Very nice video.although I don't study any subject related to this but I watched it for general knowledge.
Glad to hear that
When something is good it stops being general knowledge and becomes applicable in all spheres of life ,well done Paul.
Very good explanation! Anyone that really wants to get into electronics should get a thermal camera.
Bro do some video about elecret condenser microphone and how to connect with amplifier please....
Great video. More of these type of design and simulation videos please.
Your animations are par excellence, concept of cooling also well explained, I enjoyed it
The way you taught is outstanding highly appritiatv
Thanks, glad it was useful
Paul your videos are always so detailed. Not gonna lie I wanted to see what happen if you didn't cut the power on the cheap bench power supply.
I'm tempted to make a IGBT destruction video, it would be fun.
what a beautiful explanation
Water cooling should* be better in the case of computers. However, unless you're doing a custom loop with a proper cold plate/proper pump, once an AIO cooler reach equilibrium, it can sometimes be worse than air cooling. It's more complicated, less reliable and prone to leaking.
Not the point of the video, but people put all in one water cooling on a pedestal it doesn't deserve.
AIOs and custom loops can handle short load burst better than air coolers, but end up running worse with a sustained load if the radiator doesn't have enough capacity or the room around it heats up.
love you videos. More on electronics please!!!! you da best
thank you for clearing my doubts 😍🙏
Is it possible for electronic components to get just enough energy to not heat up but function efficiently?
Not heating up at all is not possible. If something moves against something, it creates heat as friction, in this case electrical. Try rubbing your hand against a rug, friction warms your hand. Same goes for electricity that goes through wires and components. It is possible and often desirable to use very high conductive materials and efficient design to minimize the "friction" but no, non-heating electronics are not possible.

i like the analogies that you use like voltage and pressure, current and water flowing through a pipe.
can there be more examples for more components?
That's a rather common model for electricity, so most components can be fit into it:
- Capacitors would be like water tanks
- Inductors would be like water wheels
- Resistors would be like tighter parts of the pipe
- Batteries/power sources would be like a pump
- Diodes would be like a one-way valve

This video got recommended to me after my Hard Drive got "burned out" (100+°C then it just vanished from my file explorer and from hardwareinfo) and it was constantly beeping.
EDIT: 4TB HDD form WesternDigital Red NASware 3.0
Mine was doing this too (4TB WD Red), and it had bad sectors so I eventually had to RMA it. While I have a lot of 2TB WD Green also, and they were all fine for years...
You did not even mention the reason digital semiconductors produce heat: Gate capacity. Every time a transistor switches the gate capacity has to be charged or discharged. This is why the power usage increases linear with frequency at the same voltage.
The capacity of a single MOSFET is very small but because of the high frequency and huge amount of transistors it will generate the most heat in modern CPUs.
See my new MOSFET explained video here➡️: ruclips.net/video/AwRJsze_9m4/видео.html
I think in the part about the thermal capacity of water you should also have mentioned the density difference and the difference in thermal conductivity. The way higher density and thermal conductivity of water is what enables water to carry that much more heat away. Sure the 4x more energy per K/kg is also helpful but that would just require more flow. The conductivity of 0.5918 W*m^-1*K^-1 vs 0.02535 and the density of 1 kg/cm^3 instead of 1.1/1000 kg/cm^3 is that was is doing more of the work in making the coolers smaller and more powerfull.
Good point
Wonder if Peltier plates would be any good at taking away excess heat from heatsinks, but I think there would be a condensation issues, then there's the 70 watts needed to power it. Have yet to see a Peltier used in such circuits to cool them down.
How come the temperature on all four IGBT is the same? The water should heat up on its way through this cooler, so I would expect the last one to be hotter than the first.
Literally very helpful thank you so much 🧡🧡🧡🇮🇳🇮🇳

This was more about how cooling works, but never explained WHY components get hot. What is the reason? You have to conclude from watching this yourself that its due to how much current flows through a device versus its physical size.

Its the silicon that is the problem we need graphene which is a good conductor of heat
Aluminium only. And cuprum.
I feel like my body need some aditional cooling as well.
*Thin layer of themal paste* its there to fill imperfections not to be a buffer
Yes, the thick layer was used on purpose to show a bad design. Design 2 uses a thin layer and we see the improvement
@@EngineeringMindset ah, that did not seem clear in the Video, but makes more sense
Excellent video
Thank you!
Very informative video about heat removal. I have one question please. Which type of insulator between a power transistor and a heatsink transfers heat best? Mica, silicone or a ceramic insulator provided that all have thermal paste on both sides?
Can u make a video about peilter device
I'm not an engineer, but from what I understand, you do NOT want a "thick layer of thermal compound". If the gap between your hot component and the cooling surface is too large, it will be much less efficient then if you keep the gap to a minimum.
Excellent videos need to translate to more languages by subtitles.
