Abstract
Abstract A header system of modular design capable of delivering a flow of fluid through each of a plurality of geometrically equidistant paths and of equivalent hydraulic lengths from a supply to a return point, said paths or circuits forming a multicircuit system for use in artificial ice-skating rinks and other heat exchange systems. Also the arrangement provides for self-venting of air or gases from the supply end generally upward until such gases are removed from the system.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
159 words
A modular header system comprising an elongated header having a supply chamber of a given cross section extending throughout the length of the header, and a return chamber of a given cross section larger than that of the supply chamber and extending throughout the length of the header, a median partition centrally and longitudinally disposed within said return chamber, and a plurality of U-shaped pipes forming a multicircuit system extending across an area forming a heat exchange matrix planar in configuration having an in-end and an out-end, said in-ends being coupled in serial array along the length of the supply chamber, said out-ends passing through the supply chamber and being return coupled in serial array along the length of the return chamber, said series array of in-ends and out-ends connecting the respective chambers being essentially coplanar, and eAch of the paths through the plurality of U-shaped pipes is equidistant geometrically and of equivalent hydraulic length from supply to return.
Claim 2
Dependent Claim
159 words
A modular header system comprising an elongated header having a supply chamber of a given cross section extending throughout the length of the header, and a return chamber of a given cross section larger than that of the supply chamber and extending throughout the length of the header, a median partition centrally and longitudinally disposed within said return chamber, and a plurality of U-shaped pipes forming a multicircuit system extending across an area forming a heat exchange matrix planar in configuration having an in-end and an out-end, said in-ends being coupled in serial array along the length of the supply chamber, said out-ends passing through the supply chamber and being return coupled in serial array along the length of the return chamber, said series array of in-ends and out-ends connecting the respective chambers being essentially coplanar, and eAch of the paths through the plurality of U-shaped pipes is equidistant geometrically and of equivalent hydraulic length from supply to return.
Claim 3
Dependent Claim
22 words
The invention of claim 1 wherein said supply chamber is fed from a supply pipe below the chamber to a pump connection.
Claim 4
Dependent Claim
19 words
The invention of claim 1 wherein said return chamber is coupled to a return pipe to a pump connection.
Claim 5
Dependent Claim
55 words
The invention of claim 1 wherein flow distribution baffles are disposed in the return chamber to redirect the flow from one section thereof to the other, as defined by said median partition, so that essentially equally lengthened flow paths are provided through each of the U-shaped pipes from a supply pipe to the return pipe.
Claim 6
Dependent Claim
27 words
The invention of claim 1 wherein end sections of the modular header, the coupling section of the header, and intervening sections of the header are all preformed.
Claim 7
Dependent Claim
42 words
The invention according to claim 2 wherein said header system allows gas and air bubbles to move along the fluid flow path in the upward and forward direction, effecting self-venting of the bubbles to a return pipe coupled to said return chamber.
Claim 8
Dependent Claim
43 words
The invention of claim 1 wherein said header is constructed of a central modular supply and return unit, an end modular unit terminating each end thereof, and equal lengths of intermediate modular units interposed between the central unit and the respective end units.
Claim 9
Dependent Claim
18 words
The invention of claim 7 wherein said header system is embedded in material forming a skating rink surface.
Claim 10
Dependent Claim
12 words
The invention of claim 8 wherein said material is concrete or asphalt.
