Thermal - Heat Sinks are used to transfer heat and dissipate it away from components and devices. Heat sinks work by primarily conduction and convection and are designed to increase the surface area available for the heat to dissipate. Heat sinks can be made from numerous materials, such as aluminum, copper, and graphite.
In terms of QB0402A20ESS3 application field and working principle, it is a thermoelectric heat sink that utilizes a peltier cooling system to transfer heat away from the semiconductor by transferring the heat to a heat sink, such as a copper slug or aluminum block. The thermoelectric coolers allow for efficient cooling while providing design flexibility.
The thermoelectric heat sink system of the QB0402A20ESS3 has two components: the Peltier coolers and the heat sinks. The peltier coolers are electrically–powered junctions which have an upper and a lower region, of different temperatures. When a current is passed through the Peltier cooler, heat is drawn from the upper region and is expelled in the lower region. The heat is then absorbed by the heat sink, which is attached to the cooler itself.
The heat sink is a large thermal mass which dissipates the heat. The heat sink is made of materials with high thermal conductivity which enhances heat dissipation to the atmosphere. The heat is then dissipated, either to the air or to a liquid cooling system. The heat sink design can be fine-tuned to optimally dissipate the heat generated by the thermoelectric coolers, thus improving cooling performance.
The application of the QB0402A20ESS3 thermoelectric heat sinks range from consumer electronics, such as mobile phones and laptops, to industrial applications, such as medical equipment and automotive components. It has the capacity to cool a large, hot source such as a processor or with a few thermoelectric heatsinks can cool multiple hot spots. For hot spots like laser sources, communication modules or PCBs, the QB0402A20ESS3 combines the thermoelectric heat sinks with a liquid or forced-air cooling system, depending on the application.
The QB0402A20ESS3 thermoelectric heat sinks are highly efficient and cost-effective. With their integrated design, they can be very thin, making them ideal for modern, space-constrained applications. The quick installation of the QB0402A20ESS3 ensures manufacturers are able to easily and quickly integrate the heat sinks into larger cooling assemblies for their devices.
