HEAT EXCHANGER PLATE INTERLEAVING AT ACUTE ANGLES - IN THE MANNER OF A PITCHED ROOF

Abstract

The invention relates to a heat exchanger plate with a triangular profile, wherein the triangles connect each plate together with a base line and the triangles of the two adjacent plates point towards each other with their tips and stand on the base line of the other plate. In a second profile shape, the triangles are replaced by a profile shape that resembles a house with a pitched roof. The profile elements which protrude into the area of the “condensate tray” can be shortened by A h in the area where the condensate forms to improve condensate drainage. This reduces the adhesion forces, as a result of which the condensate can drain away better. The profiles can also have a zigzag shape (seen in the direction of flow).

8. A heat exchanger having multiple heat exchanger plates stacked on top of each other and having a triangular profile, wherein the triangles of each heat exchanger plate are interconnected by a base line and the points of the triangles of two adjacent heat exchanger plates face each other and stand up on the base line of the respective other heat exchanger plate, wherein the heat exchanger plates standing on top of each other and plugged into each other have an overlap area relative to each other.

9. The heat exchanger according to claim 8, wherein the corners and points of the profiles are rounded or flattened and the parallel flanks of the pointed roof profile are made slightly conical.

10. The heat exchanger according to claim 8, wherein the overlap area of the heat exchanger plates only extends over a short length.

11. The heat exchanger according to claim 8, wherein the profile structure of the heat exchanger plates, viewed in the flow direction, takes a zigzag or sine wave course, wherein the profile structure is synchronous in all heat exchanger plates lying on top of each other.

12. The heat exchanger according to claim 8, wherein the profile structure, viewed in the flow direction, has recurring V-shaped protrusions, both for an otherwise straight profile course and for a zigzag profile, wherein the V-shaped protrusions can be rounded on the edges and have a U shape.

13. A heat exchanger having multiple heat exchanger plates stacked on top of each other, wherein the heat exchanger plates have profile shapes which are designed like a house with a pointed roof, the points of the profile shapes facing up and down, wherein the points of two heat exchanger plates plugged into each other face in opposite directions and in doing so stand on the base lines of the other heat exchanger plate, wherein adjacent house shapes with a pointed roof are interconnected by a baseline in such a manner that a rectangle facing downwards or upwards and having beveled corners is created and the heat exchanger plates standing on top of each other and plugged into each other comprise an overlap area relative to each other, wherein in order to improve the overlap area, the angle of the beveled corners of the rectangles can be increased from an angle β=45° to any desired angle within the limits of 45°<β≤90°, or wherein a rectangular overlap area is provided on the beveled corners.

14. The heat exchanger according to claim 13, wherein for improving condensate drain, the profile points do not abut the adjacent heat exchanger plate, at least in the section of the heat exchanger in which condensate formation can be expected, but have a distance Δh providing sufficient spacing from the adjacent heat exchanger plate, whereby space is provided for improving the condensate drain to the condensate draining on the adjacent heat exchanger plate in the “condensate tray”.

15. The heat exchanger according to claim 14, wherein an overlap area is provided at a distance for interlocking the heat exchanger plates if there is a Ah distance and on both sides.

16. The heat exchanger according to claim 14, wherein the overlap area only extends over a short section of the heat exchanger, and the profile members respectively adjacent to the overlap area are shortened.

17. A heat exchanger comprising: a plurality of heat exchanger plates, wherein each heat exchanger plate comprises a profile shape that repeats in a series; wherein the profile shape comprises a triangular proximal portion, a rectangular medial portion and a triangular distal portion, wherein a point of the triangular distal portion defines a distal end of the profile shape; wherein each profile shape is separated from an adjacent profile shape by a lateral space and wherein each profile shape is interconnected to an adjacent profile shape by a base line; wherein the plurality of heat exchanger plates are arranged in pairs of adjacent heat exchanger plates; wherein the distal ends of the profile shapes of a pair of adjacent heat exchanger plates are nested within the lateral spaces of the respective other heat exchanger plate of the pair of heat exchanger plates and are disposed near the base line of the respective other heat exchanger plate of the pair of heat exchanger plates; wherein the pair of heat exchanger plates define an overlap area relative to one another; and wherein an included angle (β) of the triangular proximal portion is 45°<β≤90°.

18. The heat exchanger according to claim 17, wherein the distal ends of the profile shapes are spaced a distance Δh from the base line of the respective other heat exchanger plate of the pair of heat exchanger plates.

19. The heat exchanger according to claim 17, wherein the distal ends of the profile shapes abut the base line of the respective other heat exchanger plate of the pair of heat exchanger plates.

20. The heat exchanger according to claim 17, wherein the plurality of heat exchanger plates, when viewed in a flow direction, extend along a zigzag or sine wave course.
