Definitions
- Heat exchanger board protruding into one another at an acute angle - like a pointed roof
- the invention relates to a heat exchanger board according to the preamble of
- the heat exchange surface can be increased by a small profile width (s). However, this reaches its limits in the deep-drawing process.
- the basic profile according to the invention is designed in such a way that two (predominantly equilateral) triangles (D1 and D2) (pointing in one direction) are connected to one another by a flat base line (B) (FIG. 1).
- the triangles (D1, D2) in the lower circuit board are laterally offset relative to the triangles (D3, D4) in the upper circuit board so that they can be inserted into one another (FIGS. 1, 2).
- the triangles (D1, D2, and D3, D4) of the two boards (1, 2) point towards one another with their tips, the triangle tip (3, 4) of one board standing on the base line (B) of the other board. This fixes and holds both profiles in relation to each other.
- the advantage over the zigzag profile is the better thermoformability (due to the baseline (B).
- the thermal advantage over the prior art is the short heat flow paths (a) between the parallel triangular edges (Fig. 3 and 19b).
- the included angle (a) can be of any size: 0 ° ⁇ a ⁇ 180 °, but should result in an acute angle if possible to avoid too many boards (expensive!).
- the thermal advantage is that the triangle (2) (with longer heat flow paths) is transformed into a narrow zone with parallel flanks (right and left "house wall") - provided with a "rooftop” (8) (Fig. 4a). At the same time, the heat exchange area is increased compared to the triangle.
- Heat exchange surface (detail Y, Fig. 5, 6).
- either the ride width (b) can be increased by the angle ß from 45 ° (detail X) to z. B. 60 ° to 90 ° is enlarged (Fig. 5a, b, c,) or a rectangular seat (13) (detail Z, Fig. 14a) is provided. All forms of ride should advantageously only extend over a short length (I) (viewed in the direction of flow).
- the parallel flanks of the pointed roof profile can be slightly conical (5b, 6b) for better demolding during deep drawing (Fig. 7).
- the profile according to the invention can be modified in such a way that the profile elements (y) pointing downward do not protrude into the “condensate tray” (x), but by shortening the profile height by D h (FIG. 8) Profile tip (y) hovers over the "condensate tray” (x).
- the D h shortening is also carried out with the profile tip (z) pointing “upwards” (FIG. 10).
- Heat exchanger in the flow direction of the condensing air stream is limited, in which condensation (according to calculation or test) is to be expected.
- a further increase in the heat exchange surface can be achieved if the shortened tip is converted into a rectangle (7a, 8a) (Fig. 9 to 11).
- a seat (w) to the adjacent board is required at the required distance C (Fig. 10 and 11).
- the two profile elements (u1, u2) adjacent to the seat (w) are advantageously shortened (for example by D h) in order not to have to increase the deep-drawing height (because of the seat (w)).
- the seat (w) can also be limited to a short section of the route.
- the profile variants with the profile height reduction (D h) are also useful in terms of increasing the distance (h) (distance of the profiled plates), which can reduce the number of plates for a heat exchanger
- Sinus curve-like (12) profile structure (12, 13) can increase the length of the flow thread and thus the residence time and heat exchange time, which leads to an improvement in the heat exchange performance.
- the heat exchange surface increases by the zigzag structure (FIG. 12) by approx. 6%, the surface losses in the edge area (R) (FIG. 12b) already being factored in.
- the V-shaped bulge (14) can also be installed with a zigzag profile profile (Fig. 17).
- the V-shaped bulges can also have an arcuate shape (15) (U shape) (FIG. 16).
- FIGS. 18a and b The distribution of the media in the profiles (channel distributors) is shown in FIGS. 18a and b. LIST OF REFERENCE NUMBERS
