Thermal Energy Dissipation is the transfer of heat from one medium to another. Common examples of heat transfer that take place in everyday life are the convection of air between a hot surface and a cooler surface, the conduction of heat through metal, and the radiation of heat from hot objects to cooler objects. While these processes have been studied extensively, the heat sink (901-19-2-12-2-B-0) stands out as an especially useful piece of thermal engineering due to its ability to increase the rate of heat transfer from a high temperature surface to a low temperature surface.
A heat sink is a device, usually made of metal, which connects one or more hot surfaces to a larger or deeper heat transfer medium. Heat sinks are commonly found in many everyday items including computer consoles, automotive engines, kitchen ranges, and more. In electronics, heat sinks are designed to allow for the heated component to be cooled, and may be used with additional cooling systems such as air conditioners and refrigeration systems. In mechanical systems, they are used to provide additional heat insulation from the hot component to the cold environment.
The 901-19-2-12-2-B-0 heat sink uses a combination of radiation, convection, and conduction in order to transfer heat away from the surface to which it is attached. It is constructed out of aluminum with a range of different number of pins, designed to mount the heat sink to the component to be cooled. The metal material of the pins absorbs heat energy and dissipates it via the conduction process into the surrounding air. This process is known as Passive Cooling. Additionally, its aluminum surface reflects the energy from the component away, allowing the heat to disperse more quickly. This process is known as radiation cooling.
When air passes over the heat sink fins, it flows over them and removes the heat energy from them. This is called the convection process, which is accelerated by the hot air rising from the component. This creates a ventilating effect which helps to reduce the temperature of the component more quickly. This is the most efficient method of cooling for a heat sink and requires minimal power.
The 901-19-2-12-2-B-0 heat sink utilizes a combination of conduction, radiation, and convection to transfer heat away from a hot surface. Its aluminum construction and pins allow for a strong connection to any component, and its natural fin design and ventilation effect increase the rate of efficient heat transfer from a hot component to a cooler environment.
