Beschreibung
Zusammenfassung:	A cooler having an optimized coating structure for an electric vehicle power module is provided. The cooler includes a metal cooling substrate and a coating structure. The coating structure has at least a barrier layer and a function layer. The barrier layer is formed on the metal cooling substrate. The barrier layer is a nickel coating layer or a nickel alloy coating layer having a thickness of between 0.1 μm and 0.5 μm. The function layer is a silver/silver alloy coating layer, or a copper/copper alloy coating layer having a thickness of between 0.1 μm and 0.5 μm.
