## Abstract

A communication plate extends along and is sandwiched between cylindrical communication manifolds of a first heat exchanger assembly and a second heat exchanger assembly. The communication plate includes a saddling surface arcuate in one direction and a saddling surface arcuate in the opposite direction for engaging in saddle-like fashion the cylindrical shape of the manifolds. The communication plate defines a plurality of communication plate orifices disposed along the communication plate and aligned co-axial with a plurality of communication orifices disposed along the manifolds to seal the communication orifices of the manifolds and establish distributed and sealed fluid communication between the heat exchanger assemblies.

## Claims

### Claim 1

A multi-sectional heat exchanger assembly comprising;
a first heat exchanger assembly and a second heat exchanger assembly,
each of said heat exchanger assemblies including at least one communication manifold having a cylindrical shape,
said at least one communication manifold of said first heat exchanger assembly being disposed parallel and adjacent to said at least one communication manifold of said second heat exchanger assembly,
said communication manifolds defining a plurality of communication orifices disposed linearly along said communication manifolds and wherein said communication orifices of said at least one communication manifold of said first heat exchanger assembly being co-axial with said communication orifices of said at least one communication manifold of said second heat exchanger assembly, and
a communication plate extending along and sandwiched between said communication manifolds and defining a plurality of communication plate orifices disposed linearly along said communication plate and being co-axial with said communication orifices of said manifolds for sealing said communication orifices of said at least one manifold of said first heat exchanger assembly and said at least one manifold of said second heat exchanger assembly to establish distributed and sealed fluid communication between said first heat exchanger assembly and said second heat exchanger assembly;
wherein said communication plate defines a plurality of saddling surfaces including saddling surfaces arcuate in one direction and saddling surfaces arcuate in the opposite direction for engaging said cylindrical shapes of said communication manifolds; and
wherein said communication plate is segmented into a plurality of plate segments each having a rectangular cross-section and spaced from one another and interconnected by a center strip with said arcuate saddling surfaces extending radially in opposite directions from said center strip.

### Claim 2 (depends on 1)

An assembly as set forth in claim 1 further including a plurality of tabs extending from the ends of said center strips for engaging the ends of said communication manifolds to align said orifices and stabilize said communication plate during the assembly process.
