ABSTRACT:
A heat exchanger, such as the radiator of a motor vehicle, has a nest of tubes through which liquid flows. To improve heat exchange between the liquid and the tube walls, turbulators (18) are inserted into the tubes to make the liquid flow turbulently. One form of turbulator is U-shaped and has two legs, each of which is inserted into a respective one of the tubes in the nest, via downstream ends (12) thereof. To avoid the liquid flow removing the turbulators from the tubes, stops or projections (19) are provided on either side of the bend in the turbulators. The projections may be moulded integrally with the water box which caps the downstream end of the nest of heat exchange tubes.
