A heat exchanger comprises a first header (1), a second header (2) spaced apart from the first header (1) by a predetermined distance, flat tubes (3) each of which defines two ends connected to the first and second headers (1, 2), respectively, to communicate the first and second headers (1, 2), fins (4) interposed between adjacent flat tubes (3), and a flow member defining a fluid-flow passage and forming a partition-wall-type heat-exchanging unit with the second header (2). A refrigeration system comprises a compressor, a condenser, a throttle device, and an evaporator that is the heat exchanger. The compressor, condenser, throttle device, and evaporator are connected sequentially, and at least part of refrigerant flowing out of an outlet of the condenser enters into the flow member to exchange heat with a refrigerant flowing out of an outlet of the evaporator.

An inner fin is an offset fin having a wavy cross-section that is perpendicular to an oil flowing direction, and has a louver that is partially cut and bent in a direction parallel with the oil flowing direction. The wavy cross-section is defined by alternately placing first-side convex parts and second-side convex parts. A fin height fh is defined by a distance from the first-side convex part to the second-side convex part in the cross-section. An area surrounded by the inner fin, a tube, and the first-side or second-side convex parts located adjacent with each other on the same side in the cross-section is converted into a corresponding circle having a diameter de. When a relationship of X=de/fh.sup.0.3 is defined, the diameter of the corresponding circle and the fin height respectively have dimensions that satisfy a relationship of 0.5X1.0.
