Abstract
A new fin pattern of a ribbed vortex generator for use in an air conditioner or heat exchanger. It has multiple protruding turbulent prisms placed around a round tube on a radiation fin. Each protruding turbulent prism is strip rib-shaped 3D structure with one end higher and the other end lower. Each of the multiple protruding turbulent prisms is placed around the round tube at proper intervals, and oriented to the direction that fluid flows. The higher ends of a first pair of prisms are placed on the front end entrance of the round tube and the higher ends of a second pair of prisms are placed on the exit, which improves the heat transfer but causes little pressure drop-off.
