HEAT EXCHANGER WITH STACKED PLATES

摘要

The invention relates to a heat exchanger with stacked plates, comprising a body (2) defining a U-shaped path for the circulation of gases with the exchange of heat with a cooling fluid. The inlet (3) and the outlet (4) for the gases to be cooled are adjacently arranged one above the other, and the body (2) comprises two parallel and independent upper (2a) and lower (2b) stages provided with a plurality of stacked plates (5). The invention is characterised in that the plates (5) are closed by the end (6) thereof and incorporate a passage (7), close to said end (6), defining the return path of the gas from the upper plate stage (2a) to the lower plate stage (2b) or vice versa, said passage (7) being closed by an upper plate (8) and a lower plate (9). A heat exchanger produced in this way does not require a gas tank for the return of the gas.
