Below with reference to Fig. 1-Fig. 9, the bendable heat exchanger 100 according to the embodiment of the present invention is described.
As shown in Figure 1-Figure 3, bendable heat exchanger 100 according to the embodiment of the present invention comprises: the first header 1, second header 2, flat tube 3 and fin 4, wherein, first header 1 and the second header 2 are spaced apart from each other setting, such as shown in Figure 1, first header 1 and the second header 2 in a longitudinal direction (as shown in the arrow A in Fig. 4) interval are arranged, 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, it is spaced apart on the length direction of the first header 1 and the second header 2 that flat tube 3 is multiple and multiple flat tube 3, each flat tube 3 respectively with the first header 1 and the second header 2 conducting.When the first header 1 and the second header 2 bend, the spacing between the multiple flat tubes 3 be connected with the bending section of the first header 1 and the second header 2 changes.Particularly, the spacing between the part inside bending of adjacent flat tube 3 reduces, and the spacing between the part outside bending of adjacent flat tube 3 increases.Now it is to be appreciated that " bending section " should be interpreted broadly, as long as the spacing between adjacent flat tube 3 there occurs change, namely the first header 1 is called bending section with the part be connected with the flat tube 3 that spacing changes of the second header 2.In other words, the first header 1 and the second header 2 curved section and be all called bending section by the region that curved section affects.
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 with cardinal principle corrugated and comprises main paragraph 40 and linkage section 41, main paragraph 40 is connected with linkage section 41 successively so that linkage section 41 forms crest and trough, that is, 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 transversely (as shown in the arrow B in Fig. 2) is divided into first end 410, the second end 411 and the pars intermedia between first end 410 and the second end 411 412, wherein the formation crest of pars intermedia 412 is connected with flat tube 3 with the linkage section 41 of trough, and in bending section, the formation crest of at least one end in first end 410 and the second end 411 and/or there is gap between the linkage section 41 of trough and flat tube 3.Specifically, can be now there is gap between the linkage section 4100 of first end 410 and flat tube 3, also can be there is gap between the linkage section 4110 of the second end 411 and flat tube 3, or the linkage section 4110 of the linkage section 4100 of first end 410 and the second end 411 all and between flat tube 3 exists gap, the linkage section 41 that wherein there is gap with flat tube 3 can be the linkage section 41 forming 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 side and/or trough side, and now recess forms out the gap between linkage section 41 and flat tube 3.
What needs were described 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, simultaneously because the width of fin 4 is generally equal to or is less than the width of flat tube 3, namely first end 410 and the second end 411 do not extend beyond flat tube 3 in the horizontal.Thus, when the first header 1 and the second header 2 bend, the part that fin 4 is positioned at inside bending and/or outside bending is unaffected, such as, fin 4 inside bending can not be extruded, fin 4 outside bending can not be stretched and throw off with flat tube 3 or tear, and avoids fin 4 to occur being extruded and/or falling the phenomenon such as wing, torsional deformation.
Also need to be described, 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.
