Abstract
The heat exchanger comprises tubes engaged into fins and tube plates connected to header boxes. The header boxes form on their smaller sides stirrups between the legs of which are defined inner edges on which are crimped the ends of platens formed by the tube plates. Moreover, the lugs of the side flanges are bent over on the sides of the stirrups.
Claims14
A completed and water-tight heat exchanger comprising:
- a radiator core first assembly comprising a plurality of fins and a plurality of tubes assembled together, with said fins having lateral notches,
- two collector units each comprising a head box and a tube-plate rigidly connected together, said collector units being located at opposite ends of said radiator core first assembly;
- mechanical locking means for mechanically locking together the two collector units with said radiator core first assembly therebetween, said mechanical locking means including side flanges having folded portions with the ends of said side flanges coming into abutment against both said collector units and engaged into the lateral notches of said fins, said mechanical locking means further including means placed at a fixed distance with respect to said ends of said flanges, for locking said collector units preventing them from being displaced from the radiator core first assembly.
A completed and water-tight heat exchanger comprising:
- a radiator core first assembly comprising a plurality of fins and a plurality of tubes assembled together, with said fins having lateral notches,
- two collector units each comprising a head box and a tube-plate rigidly connected together, said collector units being located at opposite ends of said radiator core first assembly;
- and
- mechanical locking means for mechanically locking together the two collector units with said radiator core first assembly therebetween, said mechanical locking means comprising a pair of side flanges extending along opposite sides of said radiator core first assembly and between said two collector units, each said side flange having lateral folded portions which engage into the lateral notches of said fins and which have ends abutting said collector units, said side flanges further having opposite end portions each of which hooks over and thereby interlocks with a cooperating portion on said collector unit located at a fixed distance with respect to the respective end of said side flange, whereby side collector units are locked together on both sides by said side flanges with said radiator core first assembly therebetween.
