Default pumping something into heat pipes?

well i was joking around in computer engineering class about opening the top of heat pipes on a cpu cooler, pumping some liquid like antifreeze inside, and resealing them. and i got to thinking, has anyone ever done something like barely similar? or would one think its worth trying on an old cooler?

It wont help the cooling of it but I can see how it will minimize heat spiking - but on long duration loads - would only make heating and cooling curves.. smoother

Well, they are already filled with something...can't remember right off the top of my head what it is though. Antifreeze isn't gonna do good though, because whatever the pipes are already filled with go through a phase change and that is why they work so well i believe.

Makes sense.. So opening the heatpipe will be disfunctional to the heatpipe right?

well glad you asked as Ive thought about running water through them actively only to find out that its completely redundant to do so !

If you can think of a way to improve cooling easily, chances are it has been done and tried.

The heatpipes are filled with some sort of gas that essentially transfers heat very well. Cutting into the heatpipes and pouring anti-freeze will just yield anti-freeze filled, worthless tubes.

Contrary to what you are thinking, they are hollow, and thus quite obviously filled with something.

Heat pipes work by allowing a liquid (called the working fluid) to evaporate, transfer, and then condense and return to the "hot side" to start the cycle over again. To open it and attempt to inject another liquid would be pointless, as a well-designed heatpipe transfers heat better than anything else we know of - and you would ruin the delicate balance set by the manufacturer.

Yeah, a filled in heatpipe = a non-functional heatpipe.
