ABSTRACT:
A method for selectively obturating at least one end of a structural module provided with rows of parallel ducts for the passage of at least two different fluids, said method comprising the steps of forming notches in those portions of the module end corresponding to the rows through which flows a first one of said fluids, said notches forming openings through the lateral wall of said module, and depositing an impervious material over the end of said module, so as to obturate the ducts through which the other fluid or fluids flow, while laterally leaving free access, by means of said notches, to the ducts through which flows said first fluid, said impervious material being sprayed in a liquid state, then gradually cooled, the angle at which it is sprayed being between 18.degree. and 30.degree. with respect to the direction of the ducts. According to alternative embodiments of the invention, the step of forming notches in the module can be removed and replaced by one of machining off the layer deposited over the portions of the module end corresponding to the rows through which flows the first fluid or by one of locating masks in front of these portions of the module end during the step of depositing the material over the end of the module.
