The invention discloses a three-dimensional thin electrolyte film condenser tube which comprises a tube body, wherein a plurality of rows of crescent pressure marks and long pressure marks axially distributed at intervals are pressed on the circumference of the tube body; each row of crescent pressure marks comprises a plurality of crescent pressure marks annularly arranged at intervals on the circumference, each row of long pressure marks comprises a plurality of long pressure marks annularly arranged at intervals on the circumference, and the pressure marks are all concave marks on the outer surface of the tube body and are all convex marks on the inner surface of the tube body. In the three-dimensional thin electrolyte film condenser tube, not only is the heat exchange area slightly increased, but also the heat exchange at both sides of the condenser tube is strengthened; and the three-dimensional thin electrolyte film condenser tube has higher heat transfer enhancement performance and ...
