Design Calculation Tutorial
Let’s assume a solid-state electronic component requires cooling to improve performance and reliability. The component resides in an environment with a maximum ambient air temperature of 35°C and dissipates 15 Watts. Cooling the component to 18°C will improve performance and reliability.
Our thermoelectric cooling system will have the following physical characteristics: the electronic component will be in direct contact with cold side of the TE cooler, and the heat sink and fan will be in direct contact with hot side of the TE cooler.
The natural flow of heat is always from hot to cold. When DC power is applied to the thermoelectric module, the cold side becomes colder than the electronic component, so heat flows naturally from the component to the TE module.
The charge carriers in the semiconductor material relocate the heat from the electronic component to the heat sink. This causes the temperature of the heat sink to rise. When the temperature of the heat sink exceeds that of the surrounding air, heat will flow naturally from the sink to the atmosphere.
