Inner chiasma spiral exterior three-dimensional diamond-type rib double-side intensify heat transfer pipe

Abstract

The invention discloses an internal crossing external spiral three-dimensional rhombus rib dual-side strengthening heat transfer tube and comprises a base body of the heat transfer tube, a rhombus rib outside the tube and a spiral groove in the tube. The base body of the heat transfer tube, the rhombus rib outside the tube and the spiral groove in the tube are integrated into a whole and the rhombus rib outside the tubes are disconnected with each other and are distributed in a spiral way along the axial direction to form a three-dimensional expanding surface on the whole external surface of the tube wall; the spiral groove are distributed in the base body of the heat transfer tube in a cross way and are presented in pairs along the direction of turning on the left and the right side. With the three-dimensional rhombus rib out of the tube, the invention increases heat transfer area while damaging a stagnant boundary layer and improving the convective heat transfer coefficient and the condensation heat transfer coefficient, meanwhile, the spiral groove cross-distributed in the tube can induce second separation flow and promote the intensification of turbulent extent while improving the convective heat transfer coefficient in the tube and increasing the capability of scale resistance. In addition, the invention has wide application range and compact structure as well as metal material saving under the same condition of heat transfer.

AI Technical Summary

Benefits of technology

This patented technology solves problems such as poor conductions caused by insufficient cooling during operation due to lack of sufficient airflow around certain parts of the tubular body's surface where temperature rises quickly when compared against other areas within the tire. By incorporating these technical features like helix shaped ridges along its outer edge, spiraling groovcks between them, and crossing spirals in the channel walls, this design enhances consistency and efficiency in conductance heat transmission while reducing impediment from surrounding regions. Additionally, adding multiple layers of triangular pyramid shape elements further increases heat transfer without compromising any desired properties (such as prevention of stalling). Overall, this new type of tube design provides improved heat dissipative capabilities at both inner and external surfaces.

Problems solved by technology

The technical problem addressed in this patented technology relates to improving heat transmission within heat exchanges without increasing their size due to enlargement of components like pipings and reducing friction between parts during operation.
