In an open environment , that is true ... but in a closed insulated box the temperature of the air inside will be almost 0 so even a small cooling element surface area will do the job , a large cooling element area is not required.

So, it doesn't really matter how big or how thick is the cooling elements?

That's right , it's all about their thermal inertia , how much heat (energy) they absorb for a rise in their temperature , and melting ice is extremely good for this absorbing a lot of heat (energy) for the phase change to water , at 0*C

I needed.

Thanks a lot.
