ABSTRACT:
An improved rod baffle heat exchanger and method for manufacturing the same are disclosed in which the tube bundle thereof comprises a plurality of tubes supported intermediate their ends by at least one outer ring and a plurality of baffle rods carried by the outer ring and extending between parallel tube rows. The baffle rods comprise circular standard rods and circular substitute rods wherein the diameter of the substitute rods differs from that of the standard rods. The use of different sized circular rods allows firm contact to be achieved between the rods and tubes of the tube bundle in order to avoid tube vibration while also avoiding the problems of rod-to-tube tolerance buildup.
