초록 ▼

A heat exchanger tube having an internal surface that enhances the heat transfer performance of the tube. The internal surface has ribs that run substantially parallel to the longitudinal axis of the tube. The ribs have a pattern of parallel notches intersecting and impressed into them at an angle oblique to the longitudinal axis. The pattern of ribs and notches increase the total internal surface area of the tube and also promote conditions for the flow of refrigerant within the tube that increase heat transfer performance.

대표청구항 ▼

An improved heat exchanger tube (50) having a wall (51) having an inner surface, an inner diameter (Di), a longitudinal axis ar) and a plurality of ribs (53) formed on said inner surface, each of said ribs having two opposite sides and a height (Hr) and extending substantially parallel to said longitudinal axes, in which the improvement comprises: a pattern of parallel notches (54), each notch having opposite first and second faces (56) opposite and inclined to each other and that portion of said notch where said first face is closest to said second face being proximal to said inner surface, impressed into said ribs to a depth (Hn) of at least 40 percent of said rib height and at an angle (b0.02 and 0.04; and the ratio between the interval (Sn) between notches in a rib and said tube inner diameter being between 0.025 and 0.07.
