Method for securing electric or electronic components, generating waste heat, to cooler of aluminum, or its alloy, with cooler enameled, at least in fastening region of components,

摘要

Electric or electronic components (5) are secured on cooler (2) of aluminum or its alloy by first applying enamel layer (3) to cooler, at least in fastening region of components. Then solderable layer (4) is deposited for each component, followed by soldering component to solderable layer. Typically cooler is completely enameled, at least on side facing components. Regions of solderable layers may be coated by spraying, preferably by cold gas spray technique. Independent claims are included for fastening appliance and cooler.
