I am always happy when others benefit from my experiences.<br /><br />Consider that you are blowing room temperature air over coils filled with warmer water. The best you can hope to get is room temperature water coming out. So if that is what you are getting, then the system is working as designed.<br /><br />While it is certainly easy to add actual cooling via the refrigeration unit, you will want to be very careful to prevent condensation inside the laser tube. That would not be good. <br /><br />If you are going to use active cooling, then I suggest you incorporate some form of temperature monitoring and automated temperature control.Tim Wehrhttps://www.blogger.com/profile/05579550070576755514noreply@blogger.comtag:blogger.com,1999:blog-2026462173127234532.post-13395459624760659172013-07-19T11:38:05.618-05:002013-07-19T11:38:05.618-05:00Hi.

That is awesome system, I have constructed mine with radiator for three fans and two temperature probes, one on water outlet from the radiator, other in reservoir. After 1h of running my 50w laser I've noticed that temperature will be always as low as temperature in room where system is, it is very disappointing because so sophisticated system should COOL DOWN rather than maintain surrounding conditions also I did some research and perfect coolant temp for CO2 laser is 13'C or below but not frost. I'm going to extend hoses and put radiator without fans to A small fridge, benefits are COOLANT WILL BE ALWAYS AS COOL AS CONDITIONS INSIDE THE FRIDGE.<br />Anyway Very Good Post.

I power it with a 12volt battery charger. You need the antifreeze. I unplugged my pump once white plain water and it only took about a minut to freeze solid.Anonymoushttps://www.blogger.com/profile/06037892475052896603noreply@blogger.comtag:blogger.com,1999:blog-2026462173127234532.post-75971757275372425542012-07-02T09:25:23.731-05:002012-07-02T09:25:23.731-05:00For a plug and play power breakout for a ATX power...For a plug and play power breakout for a ATX power supply, take a look at the ATX Box that a fellow Hive13 hacker space member is producing: http://www.gfxhax.com/cart/index.php?main_page=product_info&cPath=2_8&products_id=7<br /><br />The design is fully open sourced - the design files and BOM are all there if you want to build your own as well.Anonymoushttps://www.blogger.com/profile/14198089177396895495noreply@blogger.comtag:blogger.com,1999:blog-2026462173127234532.post-78719374088947051652012-05-25T10:15:07.877-05:002012-05-25T10:15:07.877-05:00Tim,

They told me that I could improve the cooling system efficiency by running the coolers in parallel instead of series. Place a "Y" at the inlets and outlets. They also noted that a good filter is in order because even small material circulating in the system can reduce heat transfer. It certainly would be a fairly inexpensive thing to test for additional efficiency.Tannasghhttps://www.blogger.com/profile/16825254634625158295noreply@blogger.comtag:blogger.com,1999:blog-2026462173127234532.post-11416903692850483592012-04-30T12:33:46.298-05:002012-04-30T12:33:46.298-05:00Great write up, I just ordered two.Great write up, I just ordered two.CncFanhttps://www.blogger.com/profile/09094427778144244499noreply@blogger.com
