I've created a small liquid cooler and would like to test for it's cooling capacity. The only way I know of doing it is to circulate the coolant into a small reservoir with a heating element and apply power adding heat till the cooling unit is maxed out holding at a predetermined temperature...

No I don't have it for this particular product. I'm using this a different application and was hoping someone with experience with these might be able to say whether it should be ok or not.

I'm using heatpipes in a cooling application using the same aluminum fin heat sink used to cool CPUs. I'm not sure if the temperature range of the heatpipes are the best for this application. CPU may run 40-90c and I may be getting 25-30c on the hot side and 5c on the cold. Are the ranges close...

How did you arrive at 22 F and 3 F? Using TECs is very new to me so I'm not sure what I should expect or watch out for. I appreciate your input. Am I using the formula incorrectly? I have .25 btu x 15 ft x 1 hr x 40 deg = 150 btu/ hr. 150 btu / 3.41 = 44 watts/hr . A typical refrigerator leak...

I haven't tried gradually increasing the amperage. I have tried using 6v instead of 12v which effectively halves the amperage and roughly half the cooling but decrease the waste heat generated by 75%. Could only reach 53 deg.

I have no load on the system other than ambient thru whatever surfaces and hardware there is. I intend to have other liquids enter additional lines in the trunk which are already down to temp so I'm just trying to keep them from warming up. I haven't got to that yet so the only liquids in the...

I've tried a number of variations to this and very conscious of the direction of the modules as well as the polarity. I did confirm that each module was working by applying power to each and checking to make sure they were cooling. I agree that I am picking up significant heat somewhere and...

hI'm hoping someone here is well versed at using thermoelectric cooling modules. I'm not able achieve anywhere near the cooling capacity shown in the datasheets and I'm pretty sure I've covered all possible things that could be going wrong. All I'm trying to do is maintain chilled water...
