Abstract
A heat exchanger for vehicle arranged to allow an internal circulation of at least one fluid, comprising at least a heat exchanger bundle and at least a duct (10) at least partially outside the heat exchanger bundle, the duct (10) penetrating into the heat exchanger bundle by a hole arranged in a terminal plate (8) of the heat exchanger bundle, the duct (10) comprising at least a collar (42) lining the hole, characterized in that the heat exchanger comprises a reinforcing mean (20) in touch with the collar (42) of the duct (10) and with the terminal plate (8) of the heat exchanger bundle.
Claims14
A heat exchanger for vehicle arranged to allow an internal circulation of at least one fluid, the heat exchanger comprising:
- at least one heat exchanger bundle;
- at least one duct at least partially outside the heat exchanger bundle, the duct penetrating into the heat exchanger bundle by a hole arranged in a terminal plate of the heat exchanger bundle, the duct comprising at least a collar lining the hole;
- and
- a reinforcing means in touch with the collar of the duct and with the terminal plate of the heat exchanger bundle,
- wherein the reinforcing means is of an annular shape and extends all around the duct,
- wherein the reinforcing means comprises a lower surface that contacts the terminal plate of the heat exchanger bundle and contacts a brazing ring that is disposed, around the hole, between the reinforcing means and the terminal plate of the heat exchanger,
- wherein the brazing ring, the reinforcing means, and the terminal plate are disposed to form a chamber between the brazing ring, the reinforcing means, and the terminal plate and on an outer periphery of the brazing ring,
- wherein the terminal plate comprises a neck that extends toward the collar of the duct, and
- wherein the brazing ring is disposed around the neck.
A heat exchanger for vehicle arranged to allow an internal circulation of at least one fluid, the heat exchanger comprising:
- at least one heat exchanger bundle comprising a pile of plates stacked onto one another, the pile of plates being delimited by a first terminal plate and a second terminal plate;
- at least one duct at least partially outside the heat exchanger bundle, the duct penetrating into the heat exchanger bundle by a hole arranged in one of the terminal plates of the heat exchanger bundle,
- the duct comprising at least a collar lining the hole;
- and
- a reinforcing means in touch with the collar of the duct and with the one of the terminal plates of the heat exchanger bundle, the reinforcing means being able to transfer at least a portion of forces applied on the duct to the heat exchanger by increasing contact areas between the duct and the heat exchanger,
- wherein the reinforcing means is of an annular shape and extends all around the duct,
- wherein the reinforcing means comprises a lower surface that contacts the terminal plate of the heat exchanger bundle and contacts a brazing ring that is disposed, around the hole, between the reinforcing means and the terminal plate of the heat exchanger,
- wherein the brazing ring, the reinforcing means, and the terminal plate are disposed to form a chamber between the brazing ring, the reinforcing means, and the terminal plate and on an outer periphery of the brazing ring,
- wherein the terminal plate comprises a neck that extends toward the collar of the duct, and
- wherein the brazing ring is disposed around the neck.
