FIELD: manufacturing technology.
SUBSTANCE: invention relates to heat exchanger (10) comprising internal fluid guide (32) and heat sink body (12, 12') for removing heat from the fluid. Inner side surface (20, 20') of heat sink body (12, 12') has: first section (20) comprising at least two ribs (22) that are transversely offset relative to each other; and second section (20') adjacent to first section (20), comprising at least two ribs (22') that are transversely offset relative to each other. At least one rib (22') of second section (20') is transversely offset relative to each rib (22) of first section (20) or at least one rib (22) of first section (20) is transversely offset relative to each rib (22') of second section (20'). Besides, the invention covers the method of manufacturing of such a heat exchanger.
EFFECT: direction of the fluid and removal of heat from the fluid.
