Hey people,
so i am sick of drinking warm beer when camping.......
I plan to use 2 x 11.1 V (so probably nearer 12 V) 5500mah lipo batteries connected in parallel which if im right in thinking will give me near to 120W give or take. Am i also right in thinking if i am drawing 120 W it will last for one hour assuming it can give 5.5A consistantly for 1 hour?
The peltier cells are 12V, 25W. I plan on using 3. I am told because of the seebeck effect they cause a back voltage which i obviously dont want damaging my batteries. My first question is therefore, is it as easy as placing the correct diode in series with the battery and cells? If so, can anyone reccomend any diodes rated for the power required?
My second question is regarding the pelteir cell itself. I am aware they are rated in temperature difference. I want to connect copper pipe to the peltier cell in the hope that when the peltier cell cools down the copper pipe wrapped around the beer will too. Does anyone know what will stick copper pipe to the peltier cell so that it conducts the cold temperature well. I have never seen this done be4 - is there some reason y?
If i want to cool the copper pipe will i have to place a bigger heat sink too? will they damage if they get wet off the condensation - are they water proof? Any adivce on them is much appreciated.
if anyone has any thoughts on any of it, it would be good to hear from you,
Cheers for reading,
Lee.
