HEAT EXCHANGER WITH SPACER

The invention relates to a heat exchanger with a spacer, used in machine-building industry and other fields, for the cooling a hot fluid, such as water, water-glycol mixtures, hydraulic and transmission oils, using cold air, by heat exchange. According to the invention, the exchanger consists of successive layers, consisting of some semi-boxes (5), on which some horseshoe elements (3) are placed and, at the ends of the semi-box (5), some fins (10) for hot fluid are placed, the assembly forming the channel for the hot fluid, on the semi-boxes (5) there also being two spacers (6) made of aluminium pipe, of a height equal to that of some air fins (9), fixed thereon, to result in various widths of the exchanger, the assembling being resumed to make successive channels for the hot fluid until the required number is obtained, at the upper side there being an upper wall (2), which is pre-assembled by some washers (7) and some connection pieces (8).
