Dose any body know anything about useing Heat pipes?
I am looking into useing heatpipes to remove heat from a laser modules.
would this be practical and effectiant way of removing the heat (cooling the laser within operating peramiters). This would be for a two watt laser module times three (6watts toltal) pluss drivers, pluss galvos, and maybe even the three T.E. Cooling chips.
My Q's are:
0) how hot is a 2 Watt laser module going to get?
1) What would be the best fluid to use?
2) What size tubbing inside diameter would be best?
3) how long should the heatpipe be?
4) how many individule heatpipes should be considerd for one module?
I have some knowladge of them and how they work, and how to asemble a working one. Must be in a vaccume and fluid amount is less than 1% by volume of the volume of the heatpipes toltal volume. I also know about the capulary wicking needed for those heatpipes that are horizontal in use, and I know most of the types of fluides they use in them for the different heat ranges.
I have made some useing Butane and some useing Methanol, both worked but the fluid levels were not right and they leaked over a period of three days to a non working status. So I gusse sealing them up while they contain a vaccum and keepping 1% fluid by volume and making the seal permenetly is the hard part.
Any insite from any one would be helpfull.
Thanks
