Certainly, when fin 10 upper process portion 2 number ratio is less, also all juts 2 all can be designed to same direction protruding.
As shown in the figure, selectively can also offer several hatch frames 3 on fin unit, in the present embodiment, this hatch frame 3 is selectively opened in the top of several juts 2, concrete, this hatch frame 3 first convex surfaces 21 of jut 2 is formed the first air dam surround and run through the first convex surfaces 21 and the second convex surfaces 22, which for the concrete shape of hatch frame 3, size and specifically select to be opened on jut then not do requirement, can select according to concrete service condition.
In a preferred embodiment, hatch frame 3 in the various embodiments described above is at least arranged in the surface of part jut 2, the layout quantity of hatch frame 3 specifically can be determined according to the liquid measure producing condensed water when the heat exchange amount of heat exchanger and heat exchanger work, that is, all juts 2 all can offer hatch frame 3, also part jut 2 can offer hatch frame 3, imperforation structure 3 on another part, as shown in Figure 4 and Figure 5, and hatch frame 3 extends along air-flow direction, be relatively orthogonal to airflow direction, fin 10 has larger size along air-flow direction, suitably can increase the size of hatch frame 3 like this, thus dust accretions can be avoided in hatch frame 3 place.
And, when fin 10 is installed, there is the protrusion direction of the jut 2 of hatch frame 3 at least partly approximately towards upper, be conducive to condensed water like this under self gravitation effect, come together in hatch frame 3 place, thus it is outside to flow to fin 10 from hatch frame 3, even if having dust residue like this in hatch frame 3 place, under the souring of condensed water, dust also can be outside to fin 10 with condensation flow, realizes the Automatic clearance function of dust.
In a preferred embodiment, hatch frame 3 is arranged in the first air dam, and its width is less than or equal to the width of the first air dam, and described hatch frame extends along air-flow direction; In this embodiment, because hatch frame 3 width is less than the first air dam width, which decrease the impact of hatch frame 3 on air stream, be also conducive to the first air dam flowing that air stream is formed along the first convex surfaces 21 and the second convex surfaces 22.
Above-mentioned hatch frame 3 can be arranged in the first air dam position, when fin 10 is installed, the protrusion direction with the jut 2 of described hatch frame 3 can be downward, such hatch frame 3 is located in the foot of whole jut 2, and the condensed water being conducive to jut 2 each surface formation flow to opening knot along surface and flows out.
For in above-described embodiment, described in the first convex surfaces 21, second convex surfaces 22 of jut 2 and two, side 23 surrounds hollow halfpace structure, and hatch frame 3 is the small end opening of hollow halfpace structure; This structure is conducive to the condensation flow of each side 23 of jut 2 to hatch frame 3 place, and processes fairly simple.
Jut in the various embodiments described above can by various ways, such as the first convex surfaces 21, second convex surfaces 22 and two sides 23 surround hollow hemisphere structure, hatch frame is opened in the sphere of hollow hemisphere structure, and the first air dam is sphere, and air is steadily flow through smoothly.
Jut in the various embodiments described above can by hobboing cutter roll forming, and this moulding process is fairly simple.Certainly, jut 2 also can by technological formings such as punching presses.
Please refer to Fig. 6, Fig. 6 is the structural representation of heat exchanger in a kind of specific embodiment of the present invention.
