In Fig. 1, pipe 1 has the main outer surface 200 that is formed on the opposed walls 2a and the 2b outside.Wall 2a is connected by curved wall with 2b.Wall 2a and 2b also have inner surface.Pipe 1 can be made of copper or other suitable material.Pipe 1 can be formed by the conspicuous Several Methods of those skilled in the art.For example as shown in Figure 2, pipe 1 can form like this, gets flat bar 203, utilizes roller 204 that the moulding pipe is rolled at its edge gradually, then seam 206 is welded to connect the edge.Can be by device 209 with the series-operation solder joint.Therefore the device that is used for the sequential welding adapter is not described in detail at this for known usually.At first form circular contour if manage 1, pipe is flattened the flat tube that has opposed walls 2a and 2b with formation by press 210 then.In other words, pipe may be molded to flat tube configuration and welding forming.Equally, other technology of formation pipe 1 also is suitable obviously by stretching or extruding for those skilled in the art for example.The pipe of flat opposed major surfaces illustrates the present invention although contact has basically, and the present invention also is suitable for those pipes with non-flat first type surface.For example, as shown in Figure 3, the opposed major surfaces on the pipe 201 can comprise aduncate part 212.Other profile also can comprise in the present invention.
In Fig. 4, the width W scope of pipe 1 can be to 5 inches (12.7mm to 127mm) from 1/2nd inches.The scope of the height H of pipe can be from 1.5mm to 5mm.
Another embodiment as shown in Figure 6, opposed indentations 3a and 3b can be welded with the pair of rolls 20 of embossing/converting pipe 1 by having convex surfaces 23.Thereby the convex surfaces on the roller 20 23 arranges that like this indenture 3a on the opposed major surfaces of pipe 1 is soldered to together with contact 17 places that 3b contacts in each indenture bottom surface.Pipe 1 is passing roller 20 by arrow 21 indicated directions.In above-mentioned roll process, pipe 1 also can be heated before roller 20 engages.Equally, electric current can be by pipe 1 during roll process.
In Fig. 7, the indenture 3a and the 3b that are formed on the opposite side of pipe 1 aim at layout, thereby the bottom of each indenture 3a is cold-welded to the bottom of indenture 3b to form a plurality of stylolitic parts 4.Owing to stylolitic part 4 makes refrigerant turbulent flow occur, therefore improved heat-transfer capability.
Pipe 1 has the first wall 2a and the second wall 2b that defines first type surface 200, and described first type surface is substantially parallel each other and arrange with spaced apart relation.Refrigerant pathway 24 be formed on by first and second walls around the gap in.A plurality of indenture 3a and 3b form by protruding corresponding part from the outside of each opposed first and second wall 2a and 2b, and therefore, a plurality of projectioies 25 corresponding to indenture 3a and 3b are formed on refrigerant pathway 24 sides.
In plane, each indenture is oval, and oval main shaft is along the longitudinal axis 29 of pipe 1.As shown in Figure 7, the head of opposed indentations 3a and 3b is formed in welding region 220 places and contacts with each other, thereby stylolitic part 4 is formed between the first and second wall 2a and the 2b, and each all has oval cross section.The shape of cross section of stylolitic part 4 is not limited to ellipse, and circular, avette etc. all is fine.Turn to Fig. 8, the shape of contact 17 or geometry also can comprise other shape for example rhombus 30, triangle 33, tear-drop shaped 36, two tear-drop shaped 39, hexagon 40, avette 41 and including, but not limited to polygon.For the contact 17 of arbitrary shape, equivalent diameter D
