thats pretty small for a peltier.. I wonder what thermal power it can transfer? one, two watts, as would be necessary for a high-power diode?
It's small, but it's transfer is good.
I need 5V x 0.3A = 1.5W..
The tiny peltier can handle 1.5, i'm sure, but i'll test this theory.
The REAL question is how much heat i can pump into a Dorcy or another CR123 host with decent volume.
It will require a special heatsink.
As for thermal transfer, i'll simply use my above calc to pump preciselly that much heat with PulseWidth Modulation from only 4V!
My Diode Analyzor TM now has temperature display as well!
So i'll just tweak the PWM driver till the temperature stays constant.
This should allow me to create a "Reference Lazor" for calibration purposes, as it's power will not depend on temperature anymore, since the heatsink will get the entire heat...
The MaxMass Dorcy design also utilizes the massive Dorcy host as a secondary heatsink! :evil:
The main heatsink was designed to fit it snugly and be held down by aluminum, the design is optimized for good thermal transfer into the host!
I made two such Dorcy 6x's already, they are extremelly stable with nothing but passive cooling!
