Specific implementation mode
The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention..
Embodiment 1
As shown in Figure 1, the present embodiment provides a kind of efficient heat-exchanging pipes of condensation comprising heat exchange pipe body 1 and multiple
Outer fin 2.
Specifically, the inner surface of heat exchange pipe body 1 is provided with internal thread；Multiple outer fins 2 in the shape of a spiral and are uniformly distributed
In the outer surface of heat exchange pipe body 1.Meanwhile outer 2 side of fin is equipped with the first groove 3 of the fin root for extending to outer fin 2, outside
The top of fin 2 is provided with the second groove 4, and the outer surface of the first groove 3, the second groove 4 and heat exchange pipe body 1, which is formed, is conducive to liquid
The channel of body flowing.
In the present embodiment, the first groove 3 is so that condensed refrigerant liquid flows to outer fin 2 quick and unobstructedly
Bottom, which greatly enhances the drain age velocities on 1 surface of heat exchange pipe body.
In addition, the second groove 4 that 2 top of outer fin is arranged, significantly increases the heat exchange area of heat exchange pipe body 1, together
When, the liquid condensed out is easy to overcome the influence of surface tension, quickly drip) so that gas refrigerant outer fin 2 after
Continuous condensation, so recycles, and then greatly improve heat exchange efficiency.
Preferably, outer fin 2 is spirally distributed along the outer surface of heat exchange pipe body 1, and this significantly increases refrigerants
The path length that liquid is flowed along the outer surface of heat exchange pipe body 1, and then the heat exchange area of heat exchange pipe body 1 is increased, it improves
