A heat pipe heat sink operating as a pulsating heat pipe includes a body comprising internally a closed channel in which a fluid is arranged such that part of the fluid is present in gaseous form. The channel has a periphery which is designed to be smooth. The body includes a first body portion which is embodied as curved, alternatingly curved, serpentine or U-shaped. A coolant, in particular a gaseous coolant, flows through the first body portion along a surface of the first body portion, wherein portions of the channel are arranged parallel to one another and/or in the presence of more than one channel, different channels are arranged parallel to one another. The body is composed of two block parts, with parts of the channel being arranged on a boundary area of the two block parts, respectively.
