Abstract

The invention allows to intensify heat exchange. Nlastin corrugations are made in the form of alternating rectangular projections 2 and 3 of greater and lesser length. The protrusions are located at an angle to one another with the formation of stepped channels for working environments. On the lateral faces of the protrusions, regrind pads 4 are located diagonally adjacent to the ends of the protrusions. The width of the trench of the rabbi and the protrusions that are adjacent to each other along the perimeters of the trench. On adjacent plates protrusions m. B. located at an angle from 0 to 150 °. Such an embodiment of the heat exchange element allows turbulization of the flow of the flowing medium by changing its direction of movement in mutually perpendicular planes, as well as by destroying the laminar flow structure. 1 h. the item f-ly, 8 ill. with (L with 4 oo Ci ND WITH Fig.Z

Worker c) food from aperture 8 is distributed around the jio canal 5 5 formed by protrusions 2 and 3 nlastip 1. Move along the canal 5, ()) to the azov doors 2 and 3 of one plate 1. the medium changes the direction of movement , successive passage "ko; | () dts 7 and" platforms ti in the place of the passage of the long projections 2 into the cones 1 of these projections 3.

In the well 7, the medium, changing the motion of the movement, comes from channel 5, formed by BiiicTynoM 2 of one pp 1, to channels 5, formed by short projections 3 of both plates of 1 element. In the well 7, a change in the direction of motion of the medium takes place in two mutually impacted planes, which contributes to its intense turbulence.

In the same way, the medium moves along channel 5, which is formed by projections 2 and 3 on another plate, as a result of which a constant exchange of a part of the liquid occurs in “wells x 7” between the cacatal 5 elements with its intense turbulization, and in “areas” 6, only turbulization occurs by changing the direction of movement without exchanging channel 5 of another plate I.

The medium flowing in the well 7 from one) of the 5th channel to the other breaks the laminar structure of the flow in it. After passing through channel 5 formed by protrusions 2 and 3 5 of one part of the part, the medium passes from edge to edge into channel 5 formed by the protrusions 2 and 3 of the other plate 1 and vice versa, this is the limit that | End and when driving through “wells 7.

The number of such strokes in an element is determined by the angle of intersection of the protrusions in it.

When you increase the magnitude of the angle to 150 °, the number of strokes of air is reduced, and when it decreases, it decreases. Aw, the angle a more than a 5 150 leads to a significant increase in the hydraulic resistance.

The use of the proposed plate heat exchanging element (as opposed to limestone) makes it possible to turbulize the notes of the flowing medium by changing its direction of movement in mutually peri nondical), as well as disintegrating laminar flow structure.
