Problems solved by technology

[0004] A disadvantage of the known heat exchangers is that the corners of the irregularly shaped fluid channels of such heat exchangers can undesirably hinder the flow of fluid in the side corners of the fluid channels, thereby becoming a source of turbulence and increasing the stress on the flow. resistance
Furthermore, the complex geometry of the corners requires additional seals and thus high manufacturing costs

Embodiment Construction

[0032] The present invention relates to heat exchangers and methods of manufacturing heat exchanger plates forming a heat exchanger shell or heat exchanger module. A plate heat exchanger may be formed from a plurality of heat exchanger plates with curved or folded surface portions. "Curved" and "folded" surfaces are to be understood here broadly, not only to sharply defined creases along a line of the surface, but also to more gradually curved surface regions.

[0033] The drawings are now described in more detail.

[0034] figure 1 A perspective view of a heat exchanger assembly 102 consisting of a plurality of heat exchanger plates 106 is schematically shown. The heat exchanger assembly 102 is shown to have a pronounced rectangular symmetry. A single heat exchanger plate 106 which may be formed from a planar rectangular slab will be further explained with reference to FIGS. 2-3 . Viewed from the top, figure 1 The heat exchanger plates 106 in have rectangular symmetry. ...

Abstract

The invention relates to a heat exchanger plate (106) having first surface portions (210) located along first plate edges (220) and comprising first contacting regions (214), and second surface portions (212) located along second plate edges (222). The first surface portions (210) are bent to a first side yielding a first partial fluid channel (230), and the second surface portions (212) are bent to a second side yielding a second partial fluid channel (232). The first contacting regions (214) define a plane (S). The heat exchanger plate (106) has corner surface portions (224) comprising first corner edge portions (226) and second corner edge portions (228). At least two corner surface portions (224) are bent inward with respect to the first partial fluid channel (230) such that their first corner edge portions (226) are in the plane (S), while their second corner edge portions (228) are perpendicular to the plane (S).

Description

technical field [0001] The present invention relates to a heat exchanger plate, a heat exchanger shell, and a heat exchanger assembly. Furthermore, the invention relates to a method of manufacturing a heat exchanger plate. Background technique [0002] Conventional plate heat exchangers generally consist of a plurality of heat exchanger plates between which fluid streams of different temperatures can flow in a spatially separated manner. This allows recovery of thermal energy through heat exchange between fluids. [0003] A method of manufacturing a plate heat exchanger is known from European patent document EP1,842,616. The obtained heat exchanger comprises a plurality of laminated heat exchanger plates formed from rectangular plate structural members. Each heat exchanger plate has a flange formed around the periphery of the plate. The flange includes a flat portion bent towards one side of the plate on two opposite edges of the plate; and a raised portion bent towards ...
