Abstract
Abstract A plate for directing the flow of fluids which is shaped so as to provide contact points capable of spacing it from and supporting it against similar plates, is also provided with further contact points so that by suitable arrangement of the plates, the spacing therebetween can be varied. The basic contact points on the standard plate are provided by a herring-bone pattern of V-shaped hill and valley corrugations and, preferably, the further contact points are formed by stamping the plate so that portions of the hill structure of the corrugations are provided with reversed hill and valley formations, although they may be formed by studs or projections attached to the plate.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
153 words
A plurality of heat exchanger plates arranged in stacked relationship and defining a plurality of flow channels between the plates, each plate comprising a sheet of material the surface of which forms a pattern of hill and valley corrugations, each corrugation consisting of two oppositely inclined surface portions that intersect to form a crest line, at least every second plate including a series of surface deformations that form abutments disposed within the valleys of the corrugations, the plates being arranged in pairs of two plates that are similarly oriented so that the plates which form a pair are internested and the abutments are utilized as contact points, each pair of plates having an orientation opposite that of the adjacent pairs so that spaced locations along the crest lines are utilized as contact points between plates of different pairs to prevent internesting, whereby flow channels of at least two different crosssectional areas are provided.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
12 words
The apparatus of claim 1 wherein each plate is rectangular in shape.
Claim 4
Dependent Claim
17 words
The apparatus of claim 1 wherein the corrugations of each plate are arranged in a herring-bone pattern.
Claim 5
Dependent Claim
25 words
The apparatus of claim 1 wherein said abutments are formed by reversed hill and valley corrugations pressed into the plates on which they are provided.
Claim 6
Dependent Claim
11 words
The apparatus of claim 1 wherein the corrugations are substantially V-shaped.
