Help! Need advice how can I enhance my peltier setup (aside from adding booster) to increase output voltage

Purp17 · Dec 15, 2020

Hey you guys. I badly need help for my school project. I can only produce .8 Max voltage from my 3 peltier module-series setup. How can I enhance the voltage aside from using booster? I'm afraid to add more heat at the bottom because I had experience once my module exploded due overheat. Kindly See attached files

Stick a couple of ice cubes on the fins

It looks like the "cool" side is still above the heat source; that should ideally be in a separate air stream or duct, so heat is taken away as effectively as possible.

Also try cleaning the modules & removing labels etc. then adding some grease or heatsink compound between the module surfaces and the aluminium block / heatsink.

The more effective the heat transfer in and out, the more output you will get.

Fans on the cool side will help a lot.

Thanks for the help y'all

Remember, the output of the peltier module is based on the difference in temperature of the two sides. Not the absolute temperature.
