The heat transfer device has a fin and tube block (4). At least one side part (10) has at least one expansion sector (11) in it acting in the longitudinal direction of the side part parallel to the tubes. The expansion sector is fitted at the height of the mesh structure of the fin and tube block. The expansion sector may be in the side part opposite the coolant input (6). The expansion sector may be in the form of an expansion joint. |
