Super Peltier JunctionTedster said:yes but oil is not as good a thermal conductor as heat, plus you would need a stronger pump because oil is more viscuous.

These devices were used in picnic coolers; as they consume 80.6 Watts they should be used with a large heatsink (like maybe 4x6"). We're offering them here at a bargain price but we don't want folks to smoke 'em either. Here's the data: measures 40x44x3.3mm, deltaT=79deg, Imax=8.1A, Vmax=16.1V, Thot=50deg C, Qmax=80.6W Made in USA by Tellurex under their P/N CZ1-1.4-127-1.14. Large quantity available, substantial discount for cash customers buying lots of 1000 or more.
DATA SHEET Hint: 23F004 heatsink fan assembly may be used for cooling the hotside of these.
