How does insulation increase the temperature of a solar oven cooker?
I know that insulation is a material that reduces the amount of transmission of heat, electricity, or sound, but how does it really work for solar cooking? I can't understand the process very well.
(P.s- Can you tell me some key term vocabulary for a solar oven cooker?)
Insulation in a solar box cooker is a major component of a well built solar cooker, allowing for the cooker to retain, or build up sufficient heat for effective cooking.
If you were to make a solar cooker with no insulating properties you would very quickly lose your heat out through the box into the atmosphere and would not be able to retain sufficiently high temperatures.
Insulation does just as you stated in your question above, it impedes or slows down the transfer, or conduction of heat.
Another key factor in making a good solar cooker is good reflective panels used to concentrate the suns rays onto your cookware/food.
And another is the glazing, or glass/transparent lid, or door on your solar cooker to allow the suns rays to enter your box/enclosure but not let the heat/energy escape.
One more key factor is the use of darkened, heat absorbing surfaces for your oven interior and your cookware so that the heat/energy will be captured in the dark colors.
