The heat exchanger is constructed with a plurality of fittings which are disposed in the flow passage. Each fitting is constructed of at least two groups of webs with the webs of each group disposed in spaced parallel relation and in angular relation to the axis of the flow passage. Also, each group of webs is disposed in crossing relation to the webs of the other group. The ratio of web width (b) to diameter (d) of the flow passage is in the range of from 0.08 to 0.5 while the ratio of web spacing (m) to the diameter (d) is in the range of from 0.38 to 0.9. The fittings permit improved heat transfer with reduced pressure losses and a relatively small total area.

A heat exchanger comprising means defining a flow passage having a predetermined diameter (d) along a longitudinal axis of said passage; and a plurality of fittings disposed in said flow passage, each said fitting including at least two groups of webs, each group including a plurality of webs, said webs of each group being disposed in parallel relation to each other at a predetermined spacing (m), in angular relation to said flow passage axis and in crossing relation to said webs of the other group, at least some of said webs being interconnected to each other at points of intersection thereof wherein at least two of said fittings are disposed in consecutive relation in said passage and in 90°relation to each other along said longitudinal axis.
