Dimple cooler with secondary dimples

A heat exchanger has at least one plate (10), the plate (10) comprising primary pockets (12) between which secondary pockets (14) are formed, the secondary pockets (14) being flatter and/or smaller in terms of the dimensions thereof as viewed in plan view. Due to the secondary dimples (14), the invention results in an increase in the heat exchange rate of a dimple heat exchanger, in particular a cooler plate, while the effective surface for heat exchange is not reduced. 一种热交换器，该热交换器具有至少一个板(10)，该板(10)包括主凹窝(12)，主凹窝(12)之间形成有副凹窝(14)，所述副凹窝(14)更扁平和/或就在平面图中观察到的所述副凹窝的尺寸而言更小。由于所述副凹窝(14)，本发明导致凹窝热交换器、特别是冷却器板的热交换率增大，同时用于热交换的有效表面并未减小。
