    摘要： The present invention discloses strengthened heat transmission tubes for falling film evaporators. The tube includes a tube body of the heat transmission tube and fins disposed on an outside surface of a heat transmission section of the tube body. The fins spirally surround the outside surface of the tube body of the heat transmission tube along an axial direction. The roots of the fins are integrally connected with the tube body. Each of the fins has a cross sectional T shape. Interspaces between two neighboring fins along the axial direction of the tube form small holes for coolants flow and evaporation, and form circular shape channels along the spiral direction. Each T shape fin has fin troughs along peripheral direction. The outer surfaces of the fins are disposed with grooves or extrusion lugs that guide coolants flow. Internal tube body is disposed with internal teeth. The present invention satisfies the characteristics of falling film evaporation, can guide coolant flow, and prevent excessive accumulation of coolants on outer walls of the heat transmission tubes. It also ensures the direction of coolants flow downwards and improves heat transmission efficiency of falling film evaporation.

    摘要： A condensation enhancement heat transfer pipe includes an optical pipe section, a fin section, and a transition section connecting the optical pipe section and the fin section. The outer surface of the fin section is provided with a plurality of individual fins, each of the individual fins has an acute shape of zigzag and forms an angle relative to the axial direction, an axial fin channel forms between the two adjacent ones of said individual fins along the axial direction, a peripheral fin channel forms between the two adjacent ones of said individual fins along the peripheral direction, an end, which is distributed along said axial direction, of each of said individual fins includes platforms, the fin side walls are connected with the platform by an arc, and the platforms are parallel to each other along the peripheral direction. The platform on the fin increases the heat transfer area of the sidewall, and the fin and the platform cause liquid film to flow through several turnings so as to reduce the thickness of the condensation liquid film to decrease the heat transfer resistance. The arc connection between the fin sidewall and the platform facilitates condensation liquid flow. Under the surface tension, the liquid film can flow quickly downward, thus the enhancement of the heat transfer property is maximized.
