Abstract
There is described a heat exchanger with tubes mounted in tubular bearing plates, each plate being provided with passage openings for said tubes, the cross-section area of said openings being larger than the outer cross-section of the tubes proper and a seal being provided between each tube and the tubular bearing plate, which comprises on either side of the medial plane of each plate, lips which bear resiliently and substantially tightly against the outer wall of the tube passing through the opening while retaining said tube some distance away from the edges bounding the opening.

Heat exchanger with tubes mounted in tubular bearing plates, each plate being provided with passage openings for said tubes, the cross-section area of said openings being larger than the outer cross-section of the tubes proper and a sleeve being provided between each tube and the tubular bearing plates, which includes at least one lip which bears resiliently and substantially tightly against the outer wall of the tube passing through the openings while retaining said tube some distance away from the edges bounding the openings, said sleeve being made of at least two different separable pieces, a first one being arranged at least partly inside said opening about the tube, a part of this first piece outside the opening being applied around the opening, against an outside surface of one of said bearing plates, a second piece being a ring screwed to an end of said first one, opposite to said part, against an opposite outside surface of one of said tubular bearing plates.

- and
- a sleeve arranged inside said opening about the tube some distance away therefrom, the seal being formed by two rings fastened to the sleeve ends and bearing on the tubular plate, each such ring having at least one lip facing the tube which is pressed resiliently and tightly against the tube outer wall while retaining same some distance away from the sleeve inner wall and the rings are screwed on the sleeve ends so as to bear against the surfaces of the tubular bearing plate.
