摘要: A metallic heat transfer tube, in particular for the evaporation of liquids from pure substances or mixtures on the outside of the tube. Fins are integrally formed on the outside of the tube. Recesses are arranged in the area of the base of the primary grooves and extend between the fins. The recesses are in the form of re-entrant secondary grooves. The mechanical stability of the tube is not negatively influenced because material is primarily removed from the fin flanks toward the base of the groove so that the re-entrant secondary grooves are radially open.

摘要: A heat exchanger wall for the transfer of heat from one first medium on one side of the wall to a second medium to be evaporated on the other side of the wall, with this other side having integral, aligned distributor grooves for distributing the liquid phase of the second medium. Good distribution of the liquid on the surface of the heat exchanger wall and simultaneous good vaporization characteristics are guaranteed according to the invention by the following characteristics:a) the distributor grooves cross channels having a pitch t, which channels lie below the distributor grooves,b) the distributor grooves are formed by laterally displaced material of the channel walls, with the depth T of the distributor grooves lying approximately between 30% and 90% of the channel height h, andc) the distributor grooves are connected to the channels through flared segments and/or openings in the distributor grooves.
