In the description of the present invention, it is to be understood that, components are limited using the words such as " first ", " second ", only It is merely for convenience of distinguishing corresponding components, there is no Stated otherwise such as, there is no particular meanings for above-mentioned word, therefore not It can be interpreted as limiting the scope of the invention.
As long as in addition, the non-structure each other of technical characteristic involved in invention described below different embodiments It can be combined with each other at conflict.
Fig. 1-6 shows several embodiments of condenser pipe of the present invention.Referring to Fig.1-6, condenser pipe provided by the present invention, packet The fin 12 for including tube body 11 and being arranged on 11 outer surface of tube body, also, the condenser pipe further includes for guiding on condenser pipe The groove 13 of liquid outflow, groove 13 are arranged on the outer surface of tube body 11 and extend in the same direction with fin 12.
By opening up groove 13 in the root of fin 12, so that the present invention can use 13 introduction pipe body 11 of groove and fin Condensed fluid flowing on 12, and groove 13 is further arranged to extend in the same direction with fin 12, then it can make recessed Slot 13 more sufficiently and more in time drains condensed fluid, is conducive to hydrops and is discharged more quickly, so as to so that condensation Liquid film on pipe is thinner, and thermal resistance is smaller, and then can promote the heat exchange property of condenser pipe, improves heat transfer effect.
The present invention is further explained below with reference to each embodiment shown in Fig. 1-6.
Fig. 1-2 shows one embodiment of the present of invention.As shown in Figs. 1-2, in this embodiment, condenser pipe includes tube body 11, fin 12 and groove 13, wherein fin 12 and groove 13 are arranged on the outer surface of tube body 11, and each along tube body 11 Axial direction spirally extend.
By opening up the groove 13 equally extended along axial screw in 12 bottom of fin extended along axial screw, so that can With more sufficiently and efficiently the condensed fluid in guide fins 12 and between fin 12 flows using groove 13, condensed fluid is reduced Adherency reduces the generation probability of fin 12 liquid bridges and liquid curtain, so as to enhance the drainage capacity of condenser pipe, promotes condenser pipe Heat transfer outside a tube performance, improve the heat transfer effect of condenser pipe.
As shown in Figure 1, in this embodiment, a groove 13 is equipped between every two sections adjacent fins 12.Also, by scheming 2 it is found that the cross section of the groove 13 is arc-shaped.
Wherein, advantageously, it can be set to meet between the depth a of groove 13 and the height b of fin 12: 0 < a≤ 0.3b.More advantageously, it can satisfy between the depth a of groove 13 and the height b of fin 12: a=0.1b.
It is furthermore advantageous to can satisfy between spacing d between the width c of groove 13 and adjacent two sections of fins 12: 0 < c≤ 0.9d.More advantageously, meet between the spacing d between the width c of groove 13 and adjacent two sections of fins 12: c=0.5d.
It is arranged based on above-mentioned size, condensed fluid can be more quickly discharged in groove 13, relatively efficiently between reduction fin 12 The generation probability of liquid bridge and liquid curtain, difficulty of processing is lower, and influences on the wall thickness of tube body 11 smaller.
In addition, as shown in Fig. 2, in this embodiment, the top edge of groove 13 is conducive in this way equipped with chamfering 15 into one Step accelerates the hydrops velocity of discharge, reduces thickness of liquid film, improves heat transfer effect.
Although being provided only with a groove 13 on 11 outer surface of above-described embodiment middle tube body, it is to be understood that, the number of groove 13 Amount is not limited to one, such as or two or more pieces.Fig. 3-4 is shown in which that 11 outer surface of tube body is equipped with two One embodiment of groove 13.
As shown in Figure 3-4, in this embodiment, between every two sections adjacent fins 12 be equipped with two grooves 13, and this two The cross-sectional shape of groove 13 is arc.
The case where compared to one groove 13 of setting, which is arranged two grooves 13 extended along axial screw, can So that water conservancy diversion liquid film is thinner, thermal resistance is smaller, and drain is more efficient.Meanwhile the case where compared to a plurality of groove 13 are arranged, two Groove 13 is also compared with easy processing.
Wherein, advantageously, it can be set to meet between the depth a of groove 13 and the height b of fin 12: 0 < a≤ 0.15b.More advantageously, it can satisfy between the depth a of groove 13 and the height b of fin 12: a=0.05b.
It is furthermore advantageous to can satisfy between spacing d between the width c of groove 13 and adjacent two sections of fins 12: 0 < c≤ 0.45d.More advantageously, meet between the spacing d between the width c of groove 13 and adjacent two sections of fins 12: c=0.25d.
It is arranged based on above-mentioned size, condenser pipe can be further enhanced on the basis of excessively not influencing 11 wall thickness of tube body Drainage capacity, improve the heat exchange property of condenser pipe.
It should be noted that the cross section of groove 13 is not limited to above-mentioned two in other embodiments of the invention Arc shown in a embodiment, but may be triangle (referring to Fig. 5) or inverted trapezoidal (referring to Fig. 6).
In addition, groove 13 of the invention can be processed while fin 12 forms, such as can be sprayed using particle Penetrate method, chemical the methods of engraving method or mechanical metal patterning method are machined on the outer surface of tube body 11, wherein mechanical metal cutting Method operation is more convenient, and cost performance is higher.It, can be using the methods of ultrasonic vibration also, in order to further ensure drain is smooth Clear up the contaminant particles in groove 13.
The foregoing is merely exemplary embodiment of the present invention, are not intended to limit the invention, all in spirit of the invention Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
