Abstract (en)

The present disclosure describes a pipe element for heat pipe and a cold plate utilizing the pipe element. The pipe element comprises at least one through-hole between a first opening at a first end of the pipe element and a second opening at a second end of the pipe element so that the at least one through-hole forms an evaporation section and a condenser section to the pipe element. The evaporation section comprises a first helical thread on the wall of the through-hole. The crests of the first helical thread curve away from the condenser section such that, during the use of a heat pipe comprising the pipe element, the at least one first ridge and the at least one first groove form at least one pocket for boiling coolant in the evaporator section.
