Resolder the heatpipe on a laptop? Possible?

[H1inne4ma]

Hi,

 

I got a really strange problem. The heatsink fell off the heatpipe on my new (old) HP DV7.

I have never seen that happening.

How do i get it back on there?

Solder it? Or is it some kind of adhesive?

 

Here are some pictures of the mess.

Before anyone suggest to buy a new cooler, i didnt find a suitable one.

 

Help!

Assuming there's no damage to the heat pipe itself (very questionable), you'll need to use some kind of thermal adhesive. If the heat pipe is still working, it will be completely impossible to solder that.

That being said, look on eBay for used but good parts:

 

You'll want to double check the model, but this looks close: https://www.ebay.ca/itm/163057539933?hash=item25f6fc9b5d:g:i-cAAOSwDPNbAkEz

if you know how to solder (like pipe soldering, not electronics soldering) you could try (i don't know anything about pipe soldering though so maybe that's a bad idea).

 

You could also order some thermal epoxy and try using that, that may have been what was originally on the heat pipe too.

In this video they use a special solder paste that looks like thermal paste and then when heat is applied it liquifies and spreads out. Might be worth looking at.

Without the specialized hardware to fix a desoldered heat pipe you’re looking at some really janky high temperature soldering, and if you do it wrong the heat pipe will deform as a best bad scenario, or explode as a worst case scenario.

I would try thermal adhesive and some decent clamping pressure. 
 

I would just look for a replacement, heatsinks for this model with a dedicated gpu like yours are about 25$ on Amazon.

It seems it's clamped already so just some thermal paste to fill the gaps and clamping well might be enough...

But it looks like that heatpipe might have holes anyway which would make it useless, would need testing.

Soldering and welding are two very different things. Both use different metals and require different amounts of heat or lack of heat(depending on the use case).
