A heat sink is a passive thermal management component that dissipates heat generated by power semiconductors and other hot-running parts in boiler and burner control boards. By increasing the surface area for heat transfer, it prevents overheating and ensures the longevity of electronic assemblies. In heating equipment, where components operate under continuous load, a properly sized heat sink is vital for maintaining safe temperatures. Whether you are repairing a burner control module or a boiler power supply, this heat sink helps protect sensitive electronics from thermal damage.
