Sealing.
In one or more embodiments of the invention, the root of the outer fin of three-dimensional is provided with micro-grooves.
In one or more embodiments of the invention, the outer fin of three-dimensional on the outer surface of the base tube helically
Angular distribution.
In one or more embodiments of the invention, the whole height of the outer fin of three-dimensional for 0.75mm~
1.15mm, small housing depth 0.15mm~1.35mm that its lower half is formed.
In one or more embodiments of the invention, the small chamber of circumferencial direction formation is prolonged in the outer fin lower half of three-dimensional
Body quantity 20~30.
In one or more embodiments of the invention, the outer fin of three-dimensional Spiral distribution vertically, its pitch 30~
50/inch.
In one or more embodiments of the invention, the root of the described outer fin of three-dimensional, which has, prolongs circular manner and uniformly divides
The micro-grooves of cloth, quantity 20~30.
The processing method that the present invention also proposes a kind of outer fin multiple tube of bimodulus, for manufacturing, fin is answered outside above-mentioned bimodulus
Pipe is closed, is specifically：The outer fin plow of the three-dimensional is molded in the table side of the base tube, is specifically to be based on two dimension in base tube table side
Tied silk surface and pass through tapered cutter plow and be molded.
In one or more embodiments of the invention, plow depth 0.65mm~0.85mm of the outer fin of three-dimensional.
The beneficial effects of the invention are as follows：Three-dimensional outer fin machining method is simple, and the product can take into account evaporation operating mode and also may be used
It is nervous instantly in copper resource to take into account condensing condition, it is widely used.In particular with environmental problem very severe, ' coal changes electricity '
Air energy heat pump is the important measures for solving environmental problem, and it is special that the outer fin multiple tube of the bimodulus is applied to air energy heat pump heat exchanger
It is unsuitable.Technical measure is easy to implement, and heat-transfer effect is all higher under the outer fin multiple tube both of which of bimodulus, is applicable
In batch production, it is easy to promote.
