In this video I improved the previous experiment’s results. I replaced the fixed voltage (12.17 V) power supply to a variable power supply. So, instead of supplying about 6.5 A per unit, I was only running roughly 6 A through them. That seems little, but if we think about the Watts, it is about 5-6 Watts per unit, so we gained 10-12 extra Watts. Since the cooling power is low, it is comparable with this 10-12 Watts, therefore this is a significant improvement. The results also show that I managed to get lower voltages. I actually reached the target temperature, 4°C at the bottom of the cooling box while the cold side heatsink was below 0°C. • Join my channel membership: / @curiousscientist • You can find the chart on my website: https://curiousscientist.tech/blog/pe... • If you want to support my work, please consider buying the parts using my affiliate links: • https://curiousscientist.tech/tools
