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.
Claims19
A fin pattern FOR a ribbed vortex generator comprising:
- a) a fin;
- b) at least one round tube penetratingly mounted through the fin;
- and
- c) a ribbed vortex generator positioned around each tube in a spaced arrangement, each ribbed vortex generator including at least four polyhedron prism protrusions with higher and lower ends, arranged on a concentric circle about the tube such that the higher ends of a pair of adjacent protrusions face in one direction, while the higher ends of an opposed pair on the circle face in an opposite direction.
A fin pattern for a ribbed vortex generator comprising:
- a) a plurality of spaced apart fins oriented parallel to one another;
- b) at least one round tube penetratingly mounted through the fins;
- and
- c) a ribbed vortex generator positioned around each tube in a spaced arrangement, each ribbed vortex generator including at last four polyhedron prism protrusions with higher and lower ends, arranged on a concentric circle about each tube such that the higher ends of a pair of adjacent protrusions face in one direction, while the higher ends of an opposed pair on the circle face in an opposite direction.
