Filed:

Mar 27, 1978

Appl. No.:

5/890539

Inventors:

Joseph M. O'Connor - Chicago IL
Stephen F. Pasternak - Park Ridge IL

Assignee:

Peerless of America, Inc. - Chicago IL

International Classification:

B21D 5306

US Classification:

72254

Abstract:

Heat transfer elements are made by forming a plurality of tubes extending in side-by-side relation with connector means holding adjacent tubes together, cutting and outwardly projecting surface portions of the tubes to form fins, and then severing the connector means to divide the plurality of tubes into individual heat transfer elements.

Filed:

Jul 24, 1978

Appl. No.:

5/927482

Inventors:

Joseph M. O'Connor - Chicago IL
Stephen F. Pasternak - Park Ridge IL

Assignee:

Peerless of America, Inc. - Chicago IL

International Classification:

F28F 130

US Classification:

165172

Abstract:

A heat exchanger and method of making same, which embodies laterally spaced tubes mounted in a plurality of spaced sets or assemblies of cross-fins, with adjacent ones of the sets of cross-fins being disposed at an angle to each other which is less than 180 degrees, and with the portions of the laterally spaced tubes extending between respective adjacent pairs of the sets of cross-fins being bent around the same radii.

Appl. No.:

6/063101

Inventors:

Joseph M. O'Connor - Chicago IL
Stephen F. Pasternak - Park Ridge IL

Assignee:

Peerless of America, Inc. - Chicago IL

International Classification:

F28F 304
F28F 116

US Classification:

165181

Abstract:

A tubular heat exchanger blank is comprised of a one-piece body portion having a plurality of elongated tubular members disposed in side-by-side relation to each other. Each of the tubular members includes a sidewall with the sidewall of adjacent tubular members being connected together by portions which are lesser in thickness than the adjacent sidewall and which extend the length of the body portion. The heat exchanger blank permits initial forming operations upon a plurality of elongated tubular members and subsequent manufacturing and separation steps to occur during the manufacture of heat exchanger elements.
