CORRUGATED HEAT PIPE Russian patent published in 2022 - IPC F16L55/00 

FIELD: heating.

SUBSTANCE: invention relates to a corrugated heat pipe containing a condensation area (1), an evaporation area (2), and a working medium filling the pipe, wherein at least one section of the evaporation area (2) is a corrugated pipe and wherein the corrugated pipe has corrugation vertices for collecting and retaining the working medium at least in the lower part of the wall of the corrugated pipe. In practical application, the evaporation area is buried in the ground in an almost or exactly horizontal position.

EFFECT: compared to the prototype exhibiting difficulties in installation of partitions and a high cost, in the present invention, the evaporation area for collecting and retaining the working medium is constructed directly as a corrugated pipe, so that the natural properties of the corrugated pipe are effectively used, implementing the high density and uniformity of distribution of the working medium in the evaporation area, as well as the convenience and ease of manufacture of the heat pipe and the low cost thereof; moreover, the wavy surface of the corrugated pipe increases the outer surface area of the corresponding section by approximately 20% to 30%, thereby increasing the contact area and heat exchange with the environment; use of the corrugated pipe significantly reduces the limitations for the space for movement of the working medium in the vaporised state.
