Heat transfer element for coolant cooling comprises oval tubes in ribbed block clamped together at their ends by U-section clamping element soldered into tube ends.

摘要

Two or more oval tubes (12) are clamped together at their ends (16) by a clamping element (20) soldered onto the tubes. The element (20) comes in U-section of one cross leg (22) and two side legs (24,26,28,30) and is inserted in the outermost tubes, specifically in a variant in the two tubes forming a return section of the ribbed tube block (10). The block (10) and tubeplate are installed first followed by the clamps and their soldered connection.
