water chiller for cooling laser tube cw5000

[wklaser]

we usually use chiller cw5000 to cool laser tube,we think this is a good way,and has a good result

3、Tank capacity : 6 L
5、Compressor : HITACHI BSA645CV（BSA645CR）
6、Cooling capacity : 2361 Btu/h
7、Refrigerants : R-134a
8、Charge amount : 340 g
9、Pump lift : 10 M
10、Dimension : 550 X 280 X 430 mm
11、Weight : approx.31 Kg

we also have another chiller cw3000,this model only can circle the water,but not cool it.
it has the temperature alarm,cost $180
1、Power supply： 110 VAC / 50 Hz
2、Power consumption： 140 VA max
3、Cooling water tank capacity： 9 L
4、Cooling water tank Material： stainless steel
5、Cooling： radiator that forces the wind cool
6、Amount of cooling： 65 W/℃
7、Way of circulation： forces circulation
8、Maximum water current capacity： 15 L/min
9、Maximum water pumping lift： 6 m
10、Diameter of input and output hole： 10 mm
11、External dimensions ： 470x262x373 mm
12、Weight： approx.16 Kg

Hi Willy,

For the UK Coletech advertize one on eBay for GBP 270 inc postage, import tax of approx GBP 50 would have to be added to this figure. http://cgi.ebay.co.uk/Professional-Wate ... 2307be3f80

Doesn't say which model but looks similar.

Hi Tweakie,

The one i ma after is the CW5000 refrigerated the one they advertise is just air cooled.
Coletech have quoted me approx 500us for the CW5000 the killer is the postage on $300 so not worth it will have to think about another water to cool the 80w of hell I am going to unleash.

Willyinaus, what wklaser is selling is not a good value if you’re willing to do a little research and build your own liquid cooling loop. A single 120mm radiator designed for PC water cooling can dissipate up to approximately 100watts when used in this application. The dual 120mm radiator that I’m using to cool my laser is able to dissipate over 300watts and some triple 120mm radiators can dissipate between 700-1100watts at a 10 degree delta temperature. In my option, it would be a better choice to get a radiator that can dissipate the heat given off by your 80w laser as opposed to resorting to coolers which use refrigeration or thermoelectric cooling. If you go below the ambient temperature, condensation becomes a real problem.

For reference, I suggest you read this thread: viewtopic.php?f=11&t=4

Hi Ben your right I have far better ideas now after i found out the price and they will work out a lot cheaper maybe a air cooled radiator and if I still need to cool further I guess I could add some peltier chips just need to keep an I on the temp I guess need to think of the electrickery behind it temp controller etc.
