Designing a heat sink
Web5. Heat Sink. The heat sink absorbs the heat load at the hot side of the Peltier element and dissipates it to the surrounding air. It's necessary to add some reserve when dimensioning the heat sink, to avoid that its temperature gets too high. The following diagram indicates that the heat Q h, rejected by the Peltier element, can be up to 2.6 ... WebThe design of a heat sink with optimum geometry and associated parameters establishes optimal thermal performance within practical limitations such as pressure drop, airflow dynamics, volume, and weight. For an example of heat sink optimization, let’s take a look at how a fin-type heat sink might be optimized. Fin-Type Heat Sink Optimization
