Method of assembling a unitary heat exchanger tube bundle assembly

摘要

An improved heat exchanger in which the tube bundle therein comprises a plurality of tubes supported intermediate their ends by at least one annular enlargement disposed around and frictionally secured to the outer surface of at least one of the tubes with the annular enlargement contacting the outer surface of each tube next adjacent thereto. Means are also provided for encircling and maintaining the tubes in spaced relation in contact with the annular enlargements. Method of constructing the tube bundle for the heat exchanger is also disclosed.
