Describe according to the bendable heat exchanger 100 of the embodiment of the present invention below with reference to Fig. 1-Fig. 9.
As shown in Figure 1-Figure 3, comprise according to the bendable heat exchanger 100 of the embodiment of the present invention: the first header 1, the second header 2, flat tube 3 and fin 4, wherein, the first header 1 and the second header 2 each intervals are arranged, for example as shown in Figure 1, the first header 1 and the second header 2 in a longitudinal direction (as shown in the arrow A in Fig. 4) interval arrange, and the first header 1 and the second header 2 have each other bending section one to one.
The two ends of flat tube 3 are connected with the second header 2 with the first header 1 respectively, particularly, flat tube 3 is that multiple and multiple flat tubes 3 are spaced apart on the length direction of the first header 1 and the second header 2, each flat tube 3 respectively with the first header 1 and the second header 2 conductings.In the time that the first header 1 and the second header 2 bend, the spacing between the multiple flat tubes 3 that are connected with the bending section of the first header 1 and the second header 2 changes.Particularly, the spacing between the part of bending inner side of adjacent flat tube 3 is dwindled, and the spacing between the part in bending outside of adjacent flat tube 3 increases.Now it will be appreciated that, " bending section " should be interpreted broadly, as long as variation has occurred the spacing between adjacent flat tube 3, the first header 1 is called bending section with the part that the flat tube changing with spacing 3 of the second header 2 is connected.In other words, the curved section of the first header 1 and the second header 2 and be subject to the region that curved section affects to be all called bending section.
Fin 4 is located between adjacent flat tube 3, fin 4 width is in the horizontal less than or equal to the width of flat tube 3, fin 4 longitudinally extends and comprises main paragraph 40 and linkage section 41 with cardinal principle corrugated, main paragraph 40 is connected with linkage section 41 successively so that linkage section 41 forms crest and trough, that is to say, a waveform of fin 4 comprises main paragraph 40 and linkage section 41, and now linkage section 41 forms crest and the trough of this waveform.Each fin 4 is connected with corresponding two flat tubes 3 by linkage section 41.
Fin 4 is divided into first end 410, the second end 411 and the pars intermedia 412 between first end 410 and the second end 411 along horizontal (as shown in the arrow B in Fig. 2), wherein the formation crest of pars intermedia 412 and the linkage section 41 of trough are connected with flat tube 3, and in bending section, between the formation crest of at least one end in first end 410 and the second end 411 and/or the linkage section 41 of trough and flat tube 3, there is gap.Particularly, can be now to have gap between the linkage section 4100 of first end 410 and flat tube 3, also can be to have gap between the linkage section 4110 of the second end 411 and flat tube 3, or the linkage section 4100 of first end 410 and the linkage section 4110 of the second end 411 all and between flat tube 3 exist gap, wherein having the linkage section 41 in gap with flat tube 3 can be the linkage section 41 that forms crest and/or trough.In other words, in the first end 410 of fin 4 and the second end 411, at least one end forms recess in crest one side and/or trough one side, and now recess forms the gap between linkage section 41 and flat tube 3.
What need to describe is, " there is gap " and refer to first end 410 and be not connected with flat tube 3 with the formation crest of at least one end in the second end 411 and/or the linkage section 41 of trough, the width that is generally equal to or is less than simultaneously flat tube 3 due to the width of fin 4, first end 410 and the second end 411 do not extend beyond flat tube 3 in the horizontal.Thus, in the time that the first header 1 and the second header 2 bend, it is unaffected that fin 4 is positioned at the part in bending inner side and/or bending outside, for example the fin 4 of bending inner side can not be extruded, the fin 4 in bending outside can not be stretched and throws off or tear with flat tube 3, avoids fin 4 to occur being extruded and/or falls the phenomenons such as wing, torsional deformation.
Also need to describe, the linkage section 41 of the first end 410 of fin 4 and/or the formation crest of the second end 411 and/or trough can be formed as arbitrary shape simultaneously, as long as above-mentioned linkage section 41 is not connected with flat tube 3.
