Abstract

Abstract A heat exchange assembly and method of producing the same comprising a series of dished fin members disposed in spaced relationship between to opposite, longitudinally extending side members, each of the fin members being recessed for seating a pipe in which a heat exchange fluid is circulated and having a slot terminating in the recess to provide an entry passage for the pipe, the marginal edge portions of the slot being adapted to be twisted, bent or otherwise distorted by the forced insertion of the assembly over the pipe; the convex side of the dished fin members each having a collar projecting laterally about the recesses in a diverging direction from the convex side which collars clamp the fins about the pipe when the dished fin members are flexed or buckled towards their opposite convex position.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 133 words
A heat exchange assembly comprising: a. a plurality of dished flexible fin members disposed in spaced relationship between two opposite longitudinally extending side members; b. an open recess in each of fin members to fit about a pipe for circulating a heat exchange medium; c. a narrowed slot in said fin members located between said side members and terminating in said recess to provide a yieldingly distortionable entry passage for said pipe; d. said recesses and said slots in the successive fin members being aligned with one another; e. a collar projecting laterally about said recess and extending in a diverging direction from the convex side of each of said dished fin members and f. said collar being effective to grip said pipe upon flexing said fin members away from its dished shaped.
Claim 2
Dependent Claim 133 words
A heat exchange assembly comprising: a. a plurality of dished flexible fin members disposed in spaced relationship between two opposite longitudinally extending side members; b. an open recess in each of fin members to fit about a pipe for circulating a heat exchange medium; c. a narrowed slot in said fin members located between said side members and terminating in said recess to provide a yieldingly distortionable entry passage for said pipe; d. said recesses and said slots in the successive fin members being aligned with one another; e. a collar projecting laterally about said recess and extending in a diverging direction from the convex side of each of said dished fin members and f. said collar being effective to grip said pipe upon flexing said fin members away from its dished shaped.
Claim 3
Dependent Claim 28 words
A heat exchange assembly according to claim 1 having spacer members between said fin members effective to cause said dished fin member to be flexed as a unit.
Claim 4
Dependent Claim 33 words
A heat exchange assembly, according to claim 2, having a support engaging an outermost of said fin members and tension means active upon said support to maintain said fin member under flexed tension.
