Embodiment
For making the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with embodiment also with reference to accompanying drawing, the utility model is further described.Should be appreciated that, these describe just exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present utility model.
Fig. 1 and Fig. 2 show schematically first embodiment of the present utility model, in this embodiment, a kind of New Ring-like Type corrugated connecting tube of the utility model, comprise straight length 1, one group of annular corrugated pipeline section 2 is provided with at the middle part of this straight length 1, as shown in Figure 1, the tube wall undulate vertically of this annular corrugated pipeline section 2, it comprises crest 21 alternate successively and trough 22, and the diameter D1 that in this annular corrugated pipeline section 2, trough 22 place is corresponding is identical with the diameter D of straight length 1, after making coolant media enter into annular corrugated pipeline section 2 thus, can flow efficiently.
Simultaneously, in the present embodiment, streamlined pipeline section 3 is provided with at the two ends of this annular corrugated pipeline section 2, this annular corrugated pipeline section 2 is connected with straight length 1 by streamlined pipeline section 3, the tube wall of this streamlined pipeline section 3 is same footpath variable cross section torsion structure, in particular, in the present embodiment, this streamlined pipeline section 3 arbitrary position be in cross section on vertical axial all sized by identical ellipse, and axially, oval cross section reverses to same direction successively, thus realize in the utility model, the tube wall of this streamlined pipeline section 3 is allowed to present same footpath variable cross section torsion structure.After coolant media enters into streamlined pipeline section 3 from straight length 1, the Flow Field Distribution of forcibly changing fluid is carried out by the change in flow duct cross section in streamlined pipeline section 3, thus reduce the impact of annular corrugated pipeline section 2 medium wave peak and trough convection cell, namely reduce the drag effects of the ripple stream field of annular corrugated pipeline section 2, thus ensure that air-conditioning has better refrigeration.
Streamlined pipeline section 3 is when changing Flow Field Distribution, it is more relevant to than these factors of windup-degree of the length of a/b, streamlined pipeline section 3, streamlined pipeline section 3 with the length of minor axis b the major axis a of the oval cross section of streamlined pipeline section 3, in the design process, the size of these factors selected is carried out according to the shape of ripple in annular corrugated pipeline section 2, as preferably, in the present embodiment, the major axis a of the oval cross section of this streamlined pipeline section 3 and the length of minor axis b are 1-1.33 than the scope of a/b, and the length of this streamlined pipeline section 3 is not less than the radius D/2 of straight length 1.
