Abstract
Abstract An evaporator panel having extruded sections placed one on top of another, each with a plurality of passages positioned within a pair of smooth parallel exterior walls. The passages are open at their ends, and steam headers are located on both ends of the panel to permit a uniform flow of steam throughout the passages within the panel. The passages within the panel are slightly tilted from horizontal so that steam condensate that collects within the passages flows into one of the steam headers which has thus a double function, that of supplying steam and of collecting condensate. The condensate is removed through an outlet at the bottom of the double-functioned header.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
184 words
A film evaporator panel comprising: a. a plurality of flat extruded sections disposed on edge on top of one another to form an upright panel-like member having a top and a bottom and vertical ends; b. each of said extruded sections having spaced parallel vertical front and back walls integrally connected by a plurality of substantially horizontal vertically spaced cross strips extending from end to end of the section to form parallel interior passageways across it; c. said front and back walls having smooth exterior surfaces for downwardly flowing films of cooling liquid thereover; and d. a pair of vertical headers, one of which is secured to one end of said panel-like member and the other of which is secured to the opposite end of said member to form the ends of said panel; e. each of said headers being provided with a vertical channel sealingly communicating with the adjacent ends of said passageways; and f. one of said channels having an inlet for steam for said passageways and the lower end of the other channel having an outlet for condensate from said passageways.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
31 words
A film evaporator panel according to claim 1, whErein said cross strips in said panel-like member are spaced apart equal distances so that all of said passages are the same size.
Claim 4
Dependent Claim
88 words
A film panel according to claim 1, wherein one of said headers is provided with an additional vertical passageway therethrough having an inlet at its lower end for a cooling liquid and an outlet at its upper end, said panel including an overflow trough mounted on top of said panel-like member and having an inlet at one end for receiving liquid from said outlet of said vertical passage, whereby liquid overflowing the trough can flow down its outer surfaces and said smooth exterior surfaces of said extruded sections.
Claim 5
Dependent Claim
21 words
A film evaporator panel according to claim 1, wherein said passages have a substantially rectangularly shaped cross-sectional configuration with planar walls.
Claim 6
Dependent Claim
24 words
A film evaporator panel according to claim 4, wherein the ratio of width to height of each of said passages approximates two to three.
Claim 7
Dependent Claim
28 words
A film evaporator panel according to claim 1, wherein the top and bottom of each of said extruded sections are each formed by one of said cross strips.
Claim 8
Dependent Claim
33 words
A film evaporator panel according to claim 6, wherein the bottom cross strip of each extruded section is mounted in abutting relationship on the top cross strip of the extruded section below it.
Claim 9
Dependent Claim
32 words
A film evaporator panel according to claim 7, wherein the thickness of each of said top and bottom cross strips is substantially half the thickness of the rest of said cross strips.
