Abstract

The invention concerns an attachment device ( 3 ) for a heat exchanger ( 2 ) comprising a core ( 23 ) for exchanging heat between a first fluid and a second fluid, said core ( 23 ) being provided with collectors ( 21 ) for the first fluid, said exchanger ( 2 ) comprising a cylinder ( 25 ), said cylinder ( 25 ) and one of said collectors ( 21 ) allowing the passage of said first fluid from one to the other, said attachment device ( 3 ) comprising a body, which is set up in order to close said cylinder ( 25 ), and an extension which allows the core ( 23 ) to be secured to a holder ( 4 ).
The invention also concerns a cylinder ( 25 ) which comprises such an attachment device ( 3 ), a heat exchanger ( 2 ) which comprises such a cylinder ( 25 ) and a heat exchanging module which comprises such a heat exchanger ( 2 ).

First claim

The invention claimed is:

1. An attachment device for securing a heat exchanger to a holder, the heat exchanger comprising a core for exchanging heat between a first fluid and a second fluid which comprises a hollow cylinder, said attachment device comprising:
an annular body that is configured to engage an inner wall of an opening located at a longitudinal end of the hollow cylinder, wherein the engagement of the annular body within the opening covers the opening in a cap-like manner; and
an extension for securing the core to the holder, said extension projecting from a surface of the body.

2. The attachment device as claimed in claim 1 , wherein said body and said extension are formed from a same material.

3. The attachment device as claimed in claim 1 , wherein said extension is a fixing bracket.

4. The attachment device as claimed in claim 3 , wherein said fixing bracket comprises a cutout for securing the core to the holder.

5. A heat exchanger to be secured to a holder comprising:
a core for exchanging heat between a first fluid and a second fluid, said core comprising at least one collector and a hollow cylinder;
an attachment device comprising:
an annular body that is configured to engage an inner wall of an opening located at a longitudinal end of the hollow cylinder, wherein the engagement of the annular body within the opening covers the opening in a cap-like manner; and
an extension for securing the core to the holder, said extension projecting from a surface of the body.

6. The heat exchanger as claimed in claim 5 , wherein the heat exchanger further comprises:
two or more corners, and
One or more flanges, said one or more flanges being situated on at least one of said two or more corners,
Wherein one of said two or more corners is situated in the vicinity of the attachment device and is free of said one or more flanges.

7. The heat exchanger as claimed in claim 5 wherein:
said hollow cylinder extends in a main direction of longitudinal extension,
said cylinder comprises a bottom end and a top end,
said bottom end being opposite said top end along the main direction of longitudinal extension; and
said attachment device engages the hollow cylinder at said bottom end.

8. A heat exchanging module comprising:
a heat exchanger as claimed in claim 5 ; and
a holder.

9. The heat exchanging module as claimed in claim 8 , wherein the holder is a second heat exchanger.
