    go bent, having a curved section forming an acute angle with a plane perpendicular to the longitudinal axis of the pipe, general view; in fig. 7 tube with fins, the turning parts of which are provided with notches, and parts of the elements above them are bent away from the plane perpendicular to the longitudinal axis of the pipe, at an acute angle that is common
    view; in fig. 8 - the same, with cuts of a different shape; in fig. 9 - a pipe with fins, provided with bent points on the turning parts and central grooves on the rib bases, with the parts between them bent in opposite directions, general view, in FIG. 10 - tube with orebrein, provided with notches on the turning sections and openings in the cruciform section.
    The heat exchanger comprises at least one pipe 1, provided with two finning in the form of a heat-conducting metal band, folded in accordion. The ribs of both harmonicas are placed along the axis of the pipe 1 almost parallel and in front of each other.
    The fins consist of 2 elements connected by u-shaped pivoting sections, including adjacent to pivoting sections 2 krysh 3 with costal bases 4 between the ribs 3 and welded to pipe 1 in the costal bases 4 perpendicular to its longitudinal axis.
    The turning sections 2 and krysh 3 are provided with common notches 5 directed towards the rib bases 4 (Fig. 1).
    Krysh 3 can have openings 6 for intensification of heat exchange, and turning sections 2 - to provide better flexibility (Fig. 2). The boundary layer formed on the wings x 3 is interrupted by the openings 6. In this embodiment, the heat transfer does not improve as much as in the case of common notches 6. However, this fin design is simple to manufacture and has less pressure loss on the finning.
    Krysh 3 may have pockets 7 which organize the flow of the medium through the holes (Fig. 3) and are also a heat transfer surface. This design is applicable when the environment is not a tendency to form deposits.
    When performing on turning sections 2 and krish x 3 common cuts, it is possible to perform outliers 7 (Fig. 5), which prevents the formation of stagnant zones.
    The turning sections 2 and-krish 3 can be bent with the formation of an acute angle o1 with a plane perpendicular to the longitudinal axis of the pipe 1 (Fig. 6). Both ends 3 with adjacent connecting sections 2 of the same element can be bent at different angles to one or opposite sides, which allows the organization
    for example, the rotation of the medium.
    Moreover, it is possible to perform, in which two harmonicas attached to different sides of one pipe 1 have krysh, bent to opposite sides of the other.
    At one time, the turning section 2 can be provided with a notch 8, and a part of the element located above the notches 8 is bent away from a plane perpendicular to the longitudinal axis of the pipe 1 at an acute angle L- (Figs. 7 and 8). These notches facilitate bending of the band into the harmonica even after welding the fins to the tube 1.
    Each rib base 4 can be provided with a central notch 9 which allows to bend the parts of the element located between the central notch 9 and the notches 8 in the corresponding turning area in opposite directions.
    The rib bases are attached to the pipe 1 by means of the petals 10 by spot welding. It is possible to fulfill the harmonica when the adjacent elements are angled to one another. Finning can only be on one side of pipe 1 or both. The fins and tube 1 may be joined together by welding, soft soldering or any other known method. Elements can be rectangular or whatever.
    The heat exchanger is made as follows. O-sasoM.
    On the heat-conducting metal strip, cuts are made, folded in the form of an accordion with the formation of 2 elements connected by U-shaped rotatable sections, consisting of kryshi 3 adjacent to the rotary sections 2 and rib bases 4 between them, and the harmonica is perpendicular to its longitudinal axis . The cutouts are made on the wings x 3, and after attaching the accordion to the pipe 1, at least a part of the surface of the rims 3 is bent relative to a plane perpendicular to the longitudinal axis of the pipe 1.
    The strip can be made of wire by deforming it.
