LN2 dewar in a airplane
I think it will only make things worse, because of the heat dissipation the TEC will do. If I have a sensors that produce X watts, a thermal conduction and loss through the Dewar of Y watts and a light-electricity conversion loss of Z watts. I need an amount of nitrogen that is converted to gas...- jonathanlavoie

LN2 dewar in a airplane
TEC work well in small difference of temperature. I think 240C (40C to 80 Kelvin) of difference will be too complicated and too power hungry. Another solution is a Stirling cooler, but it produce too much vibration as we have positioning requirement for the sensor of about 3µm. ---------...- jonathanlavoie

LN2 dewar in a airplane
Here's my system (at the design stage): -Two Dewar to hold each one infrared sensors. -The Dewar are filled with liquid nitrogen -The Dewar are inside a vacuum chamber, so we'll have LN2 feed through for refill and exhaust. Four in total. -The vacuum chamber is inside a small plane (bigger than...- jonathanlavoie
