How It Works
The Thermoelectric Cell Phone Charger works using a Peltier module. A Peltier module is a device that converts heat energy into electricity. The Peltier module is placed on top of a copper plate which conducts heat from a flame source, such as a sterno burner. A heat sink is placed on top of the Peltier modules to improve the heat transfer and increase the temperature difference across the Peltier module. The electricity generated from the Peltier module is driven by the temperature difference across the module.
What Can You Charge?
The Thermoelectric Cell Phone Charger will be able to charge most cell phones, including smartphones, such as I-Phones and Samsung Galaxies.
How Fast Will It Charge?
The goal is to be able charge a smarphone within three hours. This is a standard charging time for cell phones and will prove our thermoelectric charger to be a competitive option for charging cell phones.
What are the components?
As stated earlier, the main component of the thermoelectric cell phone charger are two Peltier modules. These are placed within a carbon fiber sheet, to prevent heat transfer from the sides of the Peltier modules. The goal is to drive the heat transfer from the bottom to the top of the module, creating the maximum temperature difference. The modules, sitting in the fiber sheet, are placed atop a copper sheet. A heat sink is on top of the whole configuration, which will then sit on two legs, or stands. The modules are wired in series to a USB port through a circuit board. The circuit board has four resistors, two 68 kilo-ohm and two 47 kilo-ohm.
