Breach is provided with the raised back side of fin layer, the partial cross sectional of the respective pipeline section of the pipe is contained in described In breach.Here, these breach form passage, the pipeline section of the pipe at two raised back sides for overlapping the fin layer being adjacently positioned It is contained in the passage.Between adjacent tube layer, two fin layers are respectively equipped with.Here, fin layer be formed without lack The raised back side of mouth is stacked toward each other.

The flange extended along the longitudinal direction of the pipeline section being contained in breach, the respective wall area of the pipe are provided with indentation, there Section reclines the flange.

One advantage of this structure can be simply to manufacture this fin, wherein the breach throwing one's back out in side Formed on face.

Another advantage is, especially using with small diameter and inner volume relative to larger-diameter pipe During the pipe that can be bent with more pipeloops in tube layer, must be bent under identical heat dispersal situations corresponding less tube layer this Relatively large distance can be by arranging two fins for being easier processing between corresponding tube layer between planting each tube layer for thus occurring Layer is simply bridged.

In addition, relatively large distance is allowed between each tube layer being likely to occur when using the pipe with small diameter-inner volume Particularly simply manufacture is used in the pipe group in this heat exchanger.Thus, for example for four tube layer and each tube layer difference For eight pipe groups of the pipeline section being arranged side by side in the tube layer, it is only necessary to 10 bending steps, and have to manufacture Six pipe groups of the pipeline section being arranged side by side need at least 34 bending steps in seven layers and a tube layer.

The very big gap that 2 or more fins layer are determined is arranged by by between each tube layer, be it also avoid The flow cross section constriction of fin layer, this also achieves heat exchanger specific power high

In a favourable embodiment variant of this heat exchanger, these flanges and between each tube layer is inserted into When fin layer direction of insertion extend on the contrary, this simplifies fin layer insert.

According to another favourable embodiment variant, these fin sides deform in its Longitudinal extending apart from upper non-rectilinear Ground is constituted.

Thus prevent fin layer the side opposed with breach on the raised back side fin between tube layer be stacked when Slide in the gap of adjacent fin layer
