I had recently ordered a TEC1-12706 Peltier module from amazon. I tested the module as soon as I recieved with a 1.2V Ni-Cd to make sure its working and also to make sure of the hot and cold sides. I purchased it for a small mini cooler project.So, attached the Peltier module to a CPU heat sink with fan and the cold side with a small aluminium block and added the necessary insulation etc. and I was able to cool down a small beaker of boiled hot water to ice cold, though it didn't freeze.I ran the unit for like 45 minutes. The unit was powered with a 12.61V-2400mAh (3 Cell Li-ion ICR18650-24E) pack. The initial current draw was around 3.8A but quickly dropped to 2.6-2-7A and remained stable.Tried bumping up the voltage to 14V and current draw increased to 4.3A but reduced it back since I didn't was to ruin the module. So, is it normal for the device to run at just 2.7A current draw ? because most people on the internet who brought 12706 say the current draw is 4A and above at 12V.
Update: Guys finally I managed to get my issue fixed. the current draw of 6A is infact for Vmax. At 12V the initial current draw of 3.8-4A is okay. I finally managed to get ice. Got a 30ml aluminium cylindrical vessel containing hot water at 60C in my mini cooler to ice in 15minutes!:)..The main issue was the cheap thermal paste I had used initially that I brought for just $0.95.So, purchased another brand ZP Heatsink Compound $3 thermal paste(Thermal conductivity:1.22W/m.k& Thermal Resistance:0.201C-in2/w),removed my old paste and applied this to both hot and cold side.Everything is working awesome.Never thought a bad thermal paste could cause this much bad performance."Gotta change the thermal paste on my i7 too or its gonna fry too!!:rolleyes:"
