Ribbed tube heat exchanger - has several tubes with pressed projections in ribs ensuring smooth high heat transfer flow

摘要

The ribbed tube heat exchanger has one or more tubes arranged in parallel. Local heat transfer coefficients in the region of tube outside walls as well as in the rib surfaces are high. From the plane of each rib (2) there is arranged on both sides of a tube (1) a guide channel (3a, 3b) pref. with a semicircularl cross section. This guide channel carries the fluid and the guide channels are pressed out so that the fuide channels provided in the ribs are pushed out in the same direction from the plane of the ribs (2).
