Hi I'm trying to heat a chamber (about 100 Liter volume) with ceramic IR lamps (6 units of 125w each). The goal is to have an approximately homogenate heating at the bottom of the chamber (50cm from the lamps at the moment). But is not so simple, although I manage to get the intended temperatures, on average, the central area of the chamber can surpass the borders by 4 ºC, which is a bit too much to call it homogeneous space. Which is understandable, because even though the lamps are evenly distributed through the top surface, the commonly heat area on the centred ends up receiving more heat. The question is, how to receive the heat from these 6 spots (the six lamps) and distribute equally? I've been thinking of placing a metallic mesh (2mm pores) between the lamps and the chamber, to try to have a layer of heating on top instead of the 6 spots of heat... would that work? I have to be careful with this layer, because too much isolation would result in massive overheating of the lamp side to get the intended temperatures on the chamber side. Has anyone faced this kind of unequal heating? how did you solve it?
All opinions are welcome.
Thank you.
Cheers, Luís Pereira.
Is it possible for you to heat the chamber from below? If you have some sort of heating plate or maybe even the lights but from below then the bottom of the chamber itself will get heated and transfer the heat to the rest of the chamber. Maybe it is possible to heat another medium, like water or similar, and let the heat disperse from that medium, either from below or within the chamber.
Well, not really. The idea is to simulate radiative heating on organisms...and eventually down the road we'll even treat radiative heat and convective heat separately to see how the organisms cope with these.
Thank you for your opinion.
