Water Cooling a 445?

[cod4pwns08]

Hey so this may be (and probably is) a crazy idea, but has anyone tried water cooling a housed and heat(sunk) 445 or any laser diode.

So you have the diode, then the aixiz housing (or whatever) then the heatsink, and then hollow copper tubing spun around the heatsink ran by a battery powered pump?

Anyways, just a crazy idea, feel free to shoot it down.

Seems like a really bad idea electricity and water just don't mix lol, but a good cooling concept.

:gun:

You should make it like Wickedlasers, test your laser in the Arctic and write down 100% duty cycle. They didn´t lie about the "Continious" duty cycle but I don´t expect this here at the mid-latitudes



Correct me if I´m wrong, but isn´t a computer an electric appliance? :undecided:

For a portable a tec would probably be better but for a lab I think it would be a good notable alternative.

The power isn't high enough, nor is the required operating temp low enough to require water cooling. Sure you can do it, but it's not practical.

Yeah it would be overkill for anything but a labby with multiple diodes. The purpose of water cooling is usually to move the heat elsewhere to a large radiator. It would be hard to fit the pump inside a portable and then there would be nowhere for a radiator large enough to even get rid of the heat added to the system by the pump.
I do think it would be outright awesome to see a host with heatpipes in it though. Heatpipes are the tubes that go in high end CPU coolers, they have a wax or liquid in them with a very low melting temperature and the heat causes it to circulate spreading the heat to the cooling fins.

I agree with Cyparagon.
Unless you have an array or 24 of them, whats the point.
Oic0's idea is more practical.
Pelter coolers are a good idea if you want them at room temp,
or even below.

Has anyone worked with IgorT´s "v3 heatsink-modules" yet?

 

[Razako]

How about submersing the module and driver in chilled mineral oil? You know the stuff used to insulate and cool high voltage transformers.

 

[CrazyMonkey]

Hmm.. You do know they only put out a few watts of heat max right?
It might work, if it does not absorb 445. What if it gets into the can?
You will loose power for sure, if for no other reason then reflection of the glass holding the oil in.

Post pics if you do it :yh:

Some people use oil to cool...I've personally stuck a whole computer while it was running into a tub of vegetable oil as super-cooling.

Oil can easily work, like mineral oil, this way any leaks will result in no damage. Keep in mind they sometimes use mineral oil (other times transformer oil) in high voltage transformers to insulate the coil windings...It's very commonly used for high voltage insulation, and cooling.

I like the oil idea, i saw a couple computers submerged in the stuff and its actually pretty neat

yeah that's what I was going to say, I remembered someone had posted this a while back:

I would say a simple heatsink and perhaps a small fan would suffice a single diode. I mean in my experience you don't need water cooling for any electronic device unless its heat output is over say 100watts or more. Just as an example a average quad core desktop processor in a modern PC expels well over 100watts of heat. I can't recall the users name but I saw a really inventive CPU heatsink that was drilled out to hold a Aixiz module. Ive personally used water cooling in many forms in my desktop PC builds for years now and its bulky at best, carries a risk of leakage, evaporation of the cooling liquid is an inevitability over time and pumps wear out. Seriously though modifying a CPU heatsink or even one of the heat-pipe types could be an interesting experiment Above all I would make absolutely sure the actual diode itself is making very good contact with its heatsink or all of this is in vain.

Now if there was a seperate tank built seemlessly on to the front and filled
with water and some fish swimming around in it, that would be awesome
