custom extrusion aluminum heat sink for power amplifier

custom extrusion aluminum heat sink for power amplifier The reason an amplifier has a heavy aluminum heat sink is to help dissipate heat.The heat sink is needed because no electronic component is 100% efficient.This is especially true in most audio circuits because they require a voltage drop across the output transistors in order to reproduce the audio signal. As you already know,if there is a voltage drop across a device(wire,transistor...anything) and current flowing through that device,power will be dissipated(in the form of heat) in the device.All semiconductors(transistors,rectifiers,regulators...)Which dissipate significant amounts of power are mounted tightly to the heat sink(to provide a thermal connection between the two). You should also know that electronic components become more susceptible to failure as their temperature increases.This is the reason that amplifiers (or any device which supplies or converts power) must have a heat sink.If there were no he…
