Hello guys,
Introduction: I would like to get some input about some kind of temperature amplifier.
What I have, is:
- an electrical heater (basically a resistor that is heating a square piece (20x20 mm, 50-100 W) of copper). It's insulated on 5 sides of the copper cube. Only one side is actually free to be connected to ... anything.
- I am measuring the temperature with a thermocouple in the center of this copper side: T0.
What I want:
- I want to keep T0 lower than a certain temperature, let's say: T0max = 60 C
- I want to put a device on top of this heater. The input of the device is mechanically attached to the heater. The output has its own copper surface with a thermocouple in the center, T1.
- I want to have T1 > T0. Basically I would like to reach something like 200 C.
- on top of the device, I will put a cooling device to reject heat to the ambient air.
the device should not use any other energy input than the heat that is coming out of the heater.I thought of different things that will not work (I was thinking of something like this: http://www.imeko.org/publications/tc12-2004/PTC12-2004-PL-003.pdf )...
anyways I would like some input about this. :)
