Heat-exchange element suitable for a heat exchange between first and second fluids, an exchanger core including the heat-exchange element and a heat exchanger including the exchanger core

Abstract

The present invention concerns a heat-exchange element (31, 131) for a heat exchanger (1) enabling heat exchange between a first fluid and a second fluid, said heat-exchange element (31, 131) being designed to guide said first fluid through the inside of said heat-exchange element (31, 131) and said second fluid around the outside of said heat-exchange element, said heat-exchange element (31, 131) including at least one first duct (42, 43, 44, 45; 141, 142, 143) having a first essentially cylindrical wall and a second duct (42, 43, 44, 45; 141, 142, 143) having a second essentially cylindrical wall, the at least first and second ducts (42, 43, 44, 45; 141, 142, 143) being connected to one another by a portion of the first wall adjacent to a portion of the second wall.
