Cooling fin of fluid-flowable cooler for cooling power electronics

The invention relates to a cooling fin (1) of a cooler (100) through which a fluid can flow for cooling a power electronic device (200). The cooling fin (1) comprises a profile (10) periodically repeating in a repeating direction (501), the repeating direction (501) being perpendicular to an extension direction (500) of the profile (10). The invention further relates to a cooling device (100) through which a fluid can flow for cooling a power electronic component (200), comprising such a cooling fin (1), and to a power electronic component arrangement (1000), comprising a power electronic component (200) and such a cooling device (100) through which a fluid can flow. 本发明涉及一种用于冷却功率电子器件(200)的流体能穿流的冷却器(100)的冷却肋片(1)。所述冷却肋片(1)包括沿重复方向(501)周期性重复的型材(10)，其中，所述重复方向(501)垂直于所述型材(10)的延伸方向(500)。此外，本发明还涉及一种用于冷却功率电子器件(200)的流体能穿流的冷却器(100)，其包括这种冷却肋片(1)，以及涉及一种功率电子器件装置(1000)，其包括功率电子器件(200)和这种流体能穿流的冷却器(100)。
