Thermal – Heat Sinks are devices that are commonly used in electronic circuits for dissipating excess heat generated by a process or source. Heat sinks are typically employed when mounted onto a source material, such as a computer processor, that generates a large amount of heat. Without the presence of a heat sink, the temperature of the source material will increase quickly, leading to a significant increase in energy usage and possibly even damaging the device or components within it. Thermal – Heat Sinks can be broken down into two basic categories: active and passive. Active heat sinks use fans or other means to physically move liquid or air to cool the source material; while passive heat sinks rely on natural convection and conduction to dissipate heat away from the source material.

The 678-39-S is a type of Thermal – Heat Sink specifically designed for power electronics applications. It is a type of active heat sink, that utilizes fans or a liquid cooling system to dissipate excess heat from the source material. Generally made of aluminum or copper, the 678-39-S has a slightly curved, extrudable fin design that enables it to fit various sizes of electronic components. Its fins are designed to create greater surface area for air to move heat away from the components, allowing the heat sink to effectively dissipate a larger amount of heat compared to more traditional designs. This makes the 678-39-S a great option for high-powered devices, as it can help significantly reduce the temperature of the device and keep it running safely.

In order to ensure the 678-39-S is working effectively, it must be properly installed and connected to the device. Generally, the 678-39-S will be placed on top of the device, with the fins facing away from the device. It should then be attached securely, either through screws or by using thermal paste. Additionally, if a liquid cooling system is used, the 678-39-S should also be connected to the appropriate tubing to ensure the liquid is able to move properly. Once installed and connected, the 678-39-S will be able to effectively dissipate the excess heat away from the device, ensuring it runs safely and efficiently.

Overall, the 678-39-S is a great option for dissipating excess heat from power electronics applications. Its unique fin design allows it to dissipate heat more effectively than more traditional designs, while its ability to be customized to fit various component sizes makes it a great choice for any type of application. By ensuring the 678-39-S is properly installed and connected, users can rest assured their devices will be protected from the excess heat generated and will maintain a stable, optimal temperature.
