Cooling element for an electronic component and device having an electronic component

The invention relates to a cooling element (1) for at least one electronic component, in particular a laser diode or a laser diode bar, with at least one receiving surface (2) for the at least one electronic component. The receiving surface (2) extends at least over part of the width of the cooling element (1) and has at least a first coolant guide structure (KM1) on. The coolant guide structure comprises a first plurality of substantially parallel first duct sections (3), which over the width (b The channel sections of the second group (12) are connected downstream of the channel sections of the first group (11) fluidically. The channel sections of the first and second groups (11, 12) of channel portions are coupled to each other that they are flowed through in the same direction of coolant.
