Heat-exchange radiator has protruberances on sheets from hollow plate plane facing inwards

摘要

The radiator (1) consists of several hollow plates (4) combined into a block or pack (16) and composed of paired sheets (22), enclosing at least one cavity serving as a channel. Each sheet has protruberances (26, 33') from the hollow plate plane, facing inwards and outwards. The protruberances are produced by deformation of the material.
