Understanding the Peltier Effect
The Peltier effect is the principle behind thermoelectric cooling. When an electric current flows through a circuit of two different conductors, it can transfer heat from one side of the junction to the other. This creates a temperature differential that can be harnessed for cooling or heating applications. It’s crucial for engineers and designers to understand this effect when selecting a thermoelectric module for their projects.
