Thermal - Heat Sinks

A heat sink is a device that has the ability to dissipate excess heat away from internal components and helps to maintain the component\'s temperature. The 578105B00000G heat sink is a type of standard heat sink that can be used in a variety of different applications, for example in electronic, power and telecommunication applications. Understanding the construction and the working principle behind the 578105B00000G heat sink can help you choose the right heat sink for your specific application.

578105B00000G Product Characteristics

The 578105B00000G heat sink is composed of a rectangular copper base for dispersing heat, that is equipped with a range of fins. Fins, the heat dissipation part of the heat sink, are typically aluminum alloys or copper, and are designed to increase the surface area available for cooling. As a result, the larger the amount of fins on the heat sink base, the greater the ability to dispel heat. Certain heat sink models include the Cooling Fan, which helps to increase the efficiency of the dissipation process and also help keep noise levels down. In the case of the 578105B00000G heat sink, there are 60 Aluminium alloy-based fins with a maximum temperature of 105°C.

578105B00000G Working Principle

Heat sink working principles are based on a simple law of thermodynamics: when two items of different temperature come into contact with one another, heat will always move from the warmer to the cooler object. In terms of the 578105B00000G heat sink, the component\'s base, which is typically made of copper, will come into contact with the component’s hot surface. Heat will be transferred from the source to the heat sink, and then dissipated from the heat sink’s fins. These heat sink fins have a high surface area contact that accelerates the heat transfer rate from the source to the sink. The cooling fan, if present, helps to increase the heat dissipation rate by helping to lower the thermal resistance.

578105B00000G Application Field

The 578105B00000G heat sink is suitable for a number of different applications. Generally, the use of a heat sink is necessary in electronic equipment that can generate a large amount of heat quickly. Examples of such applications are AC/DC converters, telecom base station power amplifiers, railroad electronics and equipment, and battery management systems. Although the 578105B00000G heat sink was designed for a particular application, it can be used in a variety of other applications if the desired wattage level is not exceeded.
