How Copper Heatpipes Are Made | China Factory Tour (Cooler Master)

We show how CPU cooler and GPU cooler copper heatpipes are made by Cooler Master in HuiZhou, China. These automated factories near Shenzhen make the heatpipes.

Copper heatpipes contain liquid inside to accelerate heat dissipation by using the phase change to shed energy quickly. This video shows cross-sections of sintered copper heatpipes and talks about how much liquid (and what kind of liquid) is inside of a copper heatpipe. We also show the start-to-finish process of manufacturing heatpipes, which is part of the long process to make a CPU or GPU heatsink.

Looks like it might be TIG welding, not soldering. We were told "soldering, " but it was very likely a translation issue between English/Chinese.

This video series is great. More factory/production tours. Try to see if Noctua will show you how they make air coolers that compete with water coolers.

Wasn't expecting it to just dump a load of copper powder all over everything.

[omegaelixir]

Closer and closer to the thermal paste video!

[Avalon]

Neat that they let you actually try to bend some heat pipes.

[DanPellegrino]

I had no idea it was just distiller water. I figured it was some other chemical. Interesting.

Great video guys as always, thanks for the time and care you put into all your work.

[sanitylogic]

You guys have the coolest jobs around, you know that?

The copper is recyclable. It won't be used to make pure copper, most likely, but it will most default be recycled. Copper is used in hundreds of different alloys, and there's always space for it. I think something got lost in translation, like them calling the tig welding, "soldering."

How its made: copper heatpipes, tech jesus edition.

[DrakkarCalethiel]

Thats something I always wanted to know TBH.

[iwantmypot]

Pretty neat to see how they do the sintering process. The image showing the sintered, grooved, and weave methods was especially cool. I didn't know there were multiple methods.

[thejeffchen]

I feel educated. Thank you so much, Steve.

Thank you for this. You probably are the only YT channel that will ever tour a factory like this. This content is gold. Keep it up!

[Hairless-Bear]

I'm loving this How It's Made series

[Zefram]

I watched this process on Brian's channel already, but I still watched this entire video. I'm the true hero the internet needs. You're welcome.

[shanemshort]

It's nice that the coolermaster relationship seems to have improved enough they're doing tours for you :)

[Tomatothrower]

Thanks for all of these factory tours GN Team. It's both informative and satisfying to watch, especially considering the fact that there are several levels of abstraction between something like a heatpipe and the products that we would see as consumers that incorporate them. It's easy to forget that every little thing in a computer has a story.

I actually work at a business in NA that manufactures industrial sized heat pipes. This manufacturing process is SO much more stream lined than what we do.

[osgrov]

That's a lot more work and effort than I expected. Cool to see, thanks!
