Heat Exchanger Plate and a Plate Package

Abstract

The invention refers to a heat exchanger plate (1) and a plate package for a plate heat exchanger. The heat exchanger plate extends between a primary edge zone (11a) and a secondary edge zone (12a). A centre axis (x) divides the heat exchanger plate in a primary part (11) and a secondary part (12). The heat exchanger plate includes a first end area (16), a second end area (17), and a central heat transfer area (18) therebetween. A primary porthole (21) and a secondary porthole (23) extend through the plate in the first end area and are surrounded by the respective adjoining edge area (25). The primary porthole is located on the primary part and the secondary porthole on the secondary part. A distribution area (26) extends on the first end area and has a base surface (27) extending from the primary porthole to the central heat transfer area. The base surface is inclined and located at an upper level at an upper plane in the proximity of the edge area of the primary porthole and sinks successively to a lower level in the proximity of a lower plate plane at secondary edge zone.

Description

BACKGROUND OF THE INVENTION AND PRIOR ART[0001]The present invention refers to a heat exchanger plate for a plate package for a plate heat exchanger, wherein the heat exchanger plate extends between a primary edge zone and a secondary edge zone in parallel with a central extension plane, an upper plate plane and a lower plate plane, wherein the central extension plane includes a centre axis dividing the heat exchanger plate in a primary part and a secondary part, and wherein the heat exchanger plate includes a first end area, a second end area, a central heat transfer area, which extends between the primary edge zone and the secondary edge zone from the first end area to the second end area, a primary porthole and a secondary porthole, which extend through the heat exchanger plate in the first end area and which are surrounded by a respective adjoining edge area, wherein the primary porthole is located on the primary part and the secondary porthole on the secondary part, and a distr...

Benefits of technology

[0008]The object of the present invention is to provide a heat exchanger plate intended for a plate package in a plate heat exchanger and including an improved distribution area.

Problems solved by technology

A disadvantage of such known distribution patterns is that they also contribute to a too large pressure drop over the distribution area.

Such a pressure drop deteriorates the efficiency of the plate heat exchanger and contributes to a too large heat transfer outside the central heat transfer area.

A limitation in this context is the strength of the plate heat exchanger in the distribution area.
