Heat exchanger

Abstract

The invention relates to a heat exchanger for transferring heat between two fluids with different temperature, said heat exchanger comprises a first heat exchange element (10, 11), said first heat exchange element (10, 11) having at least one core (20, 21) extending longitudinally through the heat exchange element, said at least one core (20, 21) defining a core cavity, said cavity being configured with an inlet port 22a and an outlet port 22b to receive a first fluid flowing there through, said heat exchange element (10, 11) having ribs (30) extending continuously substantially in parallel with the at least one core (20, 21) along the whole length of said core (20, 21), said ribs (30) extending radially outwardly from the core (20, 21) and being exposed to contact with a second fluid, flowing along said ribs (30). The invention being distinctive in that each said rib (30, 31) is divided into at least two radially extending fins (33, 34, 35, 36) at a radial distance from the core (20, 21), each said fin (33, 34, 35, 36) extends to a proximity of an outer casing surrounding said first heat exchanger element (10, 11) or a proximity of fins (33,34, 35, 36) of an additional heat exchanger element (10, 11), said additional heat exchanger element (10, 11) being arranged adjacent to said first heat exchanger element (10, 11), said inlet port (22a) and said outlet port (22b) being coupled to said core (20, 21) at the same end of the core (20a, 21a)
