Portion and the second protrusion are located on fin 101 and all have tip with protruding outward, and the second protrusion is in the quantity of tip than the
One protrusion is more.
Increase the micro- surface area of heat exchanger tube by the way that the first protrusion and the second protrusion are arranged on fin 101 come thermoexcell
Exchange capability of heat, liquid film can constantly be torn in the thin film drainage phase of heat exchanger tube by the tip formed on fin 101, to subtract
The exchange capability of heat of thin liquid film thickness reduction thermal resistance thermoexcell.Increase the quantity of tip, by part to improve heat exchanger tube office
The heat exchange efficiency in portion.
Optionally, the shape of tip can be one of triangle, trapezoidal and rectangle, be preferably triangle, puncture
The effect of liquid film is good.
In the first embodiment of the present invention, as shown in Figure 1, the first protrusion and the second protrusion are located on same tube body 10.
Due to the tip quantity for the first protrusion that the tip quantity of the second protrusion is greater than, area that can be poor in the heat exchange property of condenser
The second protrusion that tube body 10 is arranged on domain, improves its heat exchange property due to increasing the quantity of tip.
In the second embodiment of the present invention, as shown in Fig. 2, the heat exchanger tube includes two tube bodies 10, the first protrusion and the
Two protrusions are located on two tube bodies 10.It can be arranged on the poor region of the heat exchange property of condenser and have the second protrusion
Tube body 10, improve its heat exchange property due to improving the quantity of tip.
In the first and second embodiments of Fig. 1 and Fig. 2, the fin of tube body 1 is equipped with multiple first protrusions and multiple the
Two protrusions, multiple first protrusions are along fin 101 with the first spacing arrangement, and multiple second protrusions are along fin 101 between second

One step improves the heat exchange efficiency of the regional area of heat exchanger tube.
First protrusion and the second protrusion can be made of multiple elongated protrusions 103, and multiple elongated protrusions 103 are intersections
Or at side different height positioned at fin 101, tip is formed in the end of elongated protrusion 103.
Fig. 3-7 shows the embodiment of different protrusions, and the first protrusion and the second protrusion can be configured to as shown in fig. 3 to 7
Any one of each protrusion.
As seen in figures 3-6, protrusion 102a, 102b, 102c and 102d is elongated prominent by two, four, six and eight respectively
Portion 103 is formed, these elongated tabs 103 are located at the two sides of fin 101 and are intersections, and elongated tab 103 can also be with
It is other quantity.
In the protrusion shown in Fig. 4-6, the angle between adjacent elongated tab 103 can be it is equal, such as 90 degree,
60 degree, 40 degree, can also be different.The angle of adjacent elongated protrusion 103 is equal so that tip is evenly distributed, so that radiating efficiency
Homogenization；The angle of adjacent elongated protrusion 103 is unequal so that tip is unevenly distributed, so that local radiating efficiency enhancing.
For each protrusion shown in Fig. 3-7, elongated tab 103 can pass through annular knurl technique or ion spray technology
It is formed in fin 101.
In addition, elongated protrusion 103 can be linear or arc；As shown in figure 3, elongated tab 103 stretches out wing
The length of piece 101 is 0.05-0.5d, and d is the distance between two adjacent fins 101.And elongated tab 103 and fin 101
For height between top in the range of 0.1-0.5h, h is the height of fin 101；Preferably, this is highly 0.2h, if should
It is highly larger to will limit draining function.
The various combination that can choose multiple protrusions in Fig. 3-7 is arranged on same tube body 10 and multiple tube bodies 10, and
It is not limited to mode as depicted in figs. 1 and 2.
The present invention also provides a kind of air conditioning condensers including above-mentioned heat exchanger tube, and being in addition also disclosed a kind of includes the air-conditioning
With the air-conditioning of condenser.
According to another aspect of the present invention, a kind of processing method of air-conditioning condenser heat exchanger tube is disclosed, including following
Step: the tube body 10 for having fin 101 is provided, tubular body is used to circulate and the refrigerant of air-conditioning changes hot medium；In tube body 10
101 surface of fin on process the first protrusion and the second protrusion outstanding, the first protrusion and the second protrusion outwardly and all have point
Portion, the second protrusion are more than the first protrusion in the quantity of tip.
Optionally, the first protrusion and the second protrusion are processed on two tube bodies 10 on same tube body 10 or respectively.
Optionally, the first protrusion and second convex is processed on fin 101 by annular knurl technique or ion spray technology
Portion.
Optionally, the first protrusion or the second protrusion are processed by the way that annular knurl technique is repeated several times on fin 101.It is preferred that
Ground, the number of repetition of annular knurl technique is between 2-4.Annular knurl technique can be complete by way of increasing material technical approach or machining
At.Machining mode economy is higher, the structure is realized by control tool sharpening sequence, due to the increasing with annular knurl item number
Add, manufacturing procedure is more complicated.The protrusion 102a (such as Fig. 3) of two elongated tabs 103 can be processed by an annular knurl technique,
The protrusion 102b (such as Fig. 4) that four elongated tabs 103 can be processed by annular knurl technique twice, by the way that annular knurl technique can three times
To process the protrusion 102c (such as Fig. 5) of six elongated tabs 103, by four annular knurl techniques can process eight it is elongated prominent
