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.
