External finning consists of straight projections alternating with passes the cross sectional area of which in upper part of the wall is smaller than in its middle part, and internal finning consists of alternating passes separated with fins and having the cross sectional area of a constant value and passes with cross sectional area of a variable value, which are made as close as possible to outside surface of the straight projection. Straight projections are located opposite passes with cross sectional area of the variable value of the internal finning. In order to mix air and increase the area of the radiator heat-removing surface, there is at least one through hole in the projections.
