Building a Peltier Cooling Module for Air Intake – Open to Ideas!

Agabi.Mohamed · February 7

Hey everyone! I recently assembled a Peltier cooling module and wanted to share some insights. The goal of this setup is to cool the air entering a sealed enclosure using a TEC module and a dual heatsink system.

[Attached photos show the assembly and temperature measurements.]

Current setup:

TEC Peltier module (e.g., TEC1-12715)
Cold side radiator + fan (to cool the incoming air)
Hot side radiator + fan (to dissipate heat)
Thermal paste for better heat transfer

Challenges & Improvements:
Due to limited resources, I’m looking for ways to optimize this design with the community. Some potential improvements include:
Regulating the Peltier module’s power to improve efficiency.
Using better heatsinks and stronger fans for improved heat dissipation.
Ensuring all incoming air flows through the cold side for maximum cooling.

I’d love to hear your thoughts! Any ideas or modifications to make this system more effective? Let’s develop this concept together!

So is this just for fun orrr? As is this looks like just a tiny bit of cols air being blown into a normal pc case helping cooling a TINY bit.

Its not a closed system as is.

The second radiator doesnt add any value except making the peltier warmer?

The rear radiator is actually there to dissipate the heat from the hot side of the Peltier module. Without it, the module would quickly overheat and become inefficient.

Right now, my room temperature is 26°C, and after passing through the intake radiator, the air temperature drops to 13°C. So it’s definitely cooling the intake air.

I agree that the setup could be improved, maybe by optimizing airflow or adding insulation to make it more efficient.
