Better than Direct Contact Heatpipes

post #1 of 33
Thread Starter 
Heatpipes mounted on base:




Direct contact heatpipes:





The issue with direct heatpipes is there are terrible gaps. So how about base with heatpipes solder into the base? The base will have holes drilled into it horizontally. Then the heatpipes are bonded to the base. The inefficiency of the bond doesn't matter since the heat is transferred via the gas INSIDE the tube/base. This will give best of both designs. More efficient heat transfer to the heatpipe (one material instead of two materials and gap) while being about to maintain a flat base.

I'm not getting what you are trying to say. Sorry.

In my mind the heat pipes do make more sense as you are not heating up a huge chunk of metal prior to the heat being transfered to the heat pipes. Which then stays hotter. But then again I have never tried the TRUE I just have a Xigmatek.

Sorry, I can't "bold" or "italic" enough of that statement to try and emphasise the point you are trying to make.

Heating up the chunk of metal? Thermodynamics says this doesn't matter since the heat will move to the heatpipes since they are cooler. The issue is that there are two additional thermal inefficient layers (the base and pipe-base interface). My design removes this.

I think he means that they should just solder the heatpipes into coolers such as a Xigmatek instead of just letting them rest or using some kind of epoxy.

Yup, solder open heatpipe ends into the base. Make the base PART of the heatpipes.

Actually the direct touch is a pretty sufficient design compared to a regular plate-pipe-plate design.

They just need to work on it a little. My Xigmatek is great but I was considering taking some solder and filling in the little gaps between the pipes and then doing some sanding with a dremel and then lapping.

Now that would be a better design.

Since the solder's melting point is around 90c? it would heat up faster and maybe help even enhance the heat dissipation. Of course, I have no scientific data to back that thought up but... whatever

Now I get it sorry. The pain medication has kicked in and its about bed time.

I had heard about this and was going to get the little brother to braze this for me. He's a plumber with all the cool tools and good brazing rods.

I just ordered an OCZ Vendetta 2 and I hope that it performs. The only thing is having a good fan to go with it. Any suggestions!?!!?

My design already takes care of that by NOT having any gaps in the first place. Plus it would provide better heatpipe to CPU contact
