Abstract
A heat exchanger including a collecting tank having an outwardly extending flange around an edge, a tube plate having a connection edge, tubes having ends extending into openings in the tube plate, and an intermediate plate having an edge lying against the connection edge of the tube plate. The connection edges of the intermediate plate and the tube plate are both mechanically connected to the flange of the collecting tank. Pins in the corners of one of the tube plate and the intermediate plate secure the tube plate and intermediate plate together. The connection edge of the plates include protrusions bendable onto the edge flange of the collecting tank.
Claims12
A heat exchanger, comprising:
- a collecting tank having an outwardly extending flange around an edge;
- a tube plate having a connection edge;
- tubes having ends extending into openings in said tube plate;
- and
- an intermediate plate having an edge lying against the connection edge of said tube plate;
- wherein said connection edges of said intermediate plate and said tube plate are both mechanically connected to the flange of said collecting tank.
A method of producing a heat exchanger, comprising the steps of:
- assembling a heat exchanger core of the flat tubes and ribs;
- mounting a tube plate and an intermediate plate on the ends of said flat tubes;
- metallically joining said tubes, ribs, tube plate and intermediate plate into a unit;
- mechanically connecting a collecting tank to said tube plate and said intermediate plate by deforming both of said tube and intermediate plates.
