What is a heat sink?low, especially when used in conjunction with fans.Heat sinks provide a base level of heat dissipation that forms the backbone of any efective thermal management system. Regardless of the specific layout, thermal management components should be selected early in the electronics.
Why is a heat sink important?Since air is a good thermal insulator, it is important that a heat sink is used to increase the overall heat transfer area to the ambient, i.e., the overall thermal performance, R θ heat sink-ambient, as shown in Figure 1. This is especially true for power device packages.
How does a heat sink work?electronics at a sustainable operating temperature. A passive component made from metals with high thermal conductivity, heat sinks disper e heat by drawing it away from sensitive circuitry. Heat sinks may be cooled by liquids or simple air low to remove heat more efectively from the system. They may also incorporate fins to direct air.
How do I choose a heat sink insulator?washer slightly increases the thermal resistance. Choose an insulating material between the package and heat sink for optimal thermal performance.
