Abstract

A connector 10 attached to a heat exchanger 72 is a forged part and has a main body 12 generally in the shape of a tube with a bend. The connector outlet 22 is supported by a rib 40 depending from the bent over end of the main body 12 that is brazing to the heat exchanger 72 face; or by a tongue 92 of a heat exchanger sheet 70. The support prevents drooping during brazing, and provides extra resistance to leverage forces during fitting. The tongue 92 may be brazed to the connector 10. The connector 10 may be a push-fit to the heat exchanger 72 prior to brazing.

Description

A Connector for a Heat Exchanger and the Combination of a Connector and a Heat Exchanger The invention relates to a connector for a heat exchanger and the combination of a connector and a heat exchanger.
EP-A-82 1213 relates to a known heat exchanger and discloses a connector which is machined from a solid rectangular block of aluminium alloy. This uses a substantial amount of metal to define the required bores for fluid flow.
According to one aspect of the invention there is provided the combination of a heat exchanger and a connector, the connector having a main body generally in the shape of a tube with a bend therein, the connector being connected at its inlet end to a face of the heat exchanger and the combination including a support extending between the outlet end of the connector or adjacent thereto and the said face of the heat exchanger.
By making the connector with a main body generally in the shape of a tube, less material is used. The support provides support in relation to any forces on the bent outer end of the connector towards the face of the heat exchanger.
The support may be connected to the main body of the connector or may be connected to the heat exchanger and preferably is attached to both the main body of the connector and the face of the heat exchanger. The support thus also provides a more secure connection between the connector and the face of the heat exchanger. The connector may include a screw thread at its outlet end. A hose may be attached to the connector by a screw threaded connection, and the force from use of a spanner is also resisted by the support acting between the connector and the face of the heat exchanger. The main body of the connector may be attached to the heat exchanger by a brazed connection. The support may be attached to the main body of the connector andlor the heat exchanger by a brazed connection. This provides additional surface area of connection.
In one embodiment the support is part of the connector. The support may be an integral part of the connector. The connector may be a forged connector and the support may be part of the forging.
In another embodiment, the support is part of the heat exchanger. The support may be integral with a part of the heat exchanger. The support may be integral with the said face of the heat exchanger. The support may be constituted by a flange bent from a sheet forming the said face of the heat exchanger.
According to another aspect of the invention, there is provided a connector for a heat exchanger, the connector having a main body generally in the shape of a tube with a bend therein, the connector being arranged to be connected at its inlet end to a face of a heat exchanger and the connector including a support extending from the outlet end of the connector or adjacent thereto to support the end of the connector on the said face of the heat exchanger.
The connector may be a forged connector with the bore therethrough being machined in the forging.
According to another aspect of the invention there is provided a forged connector for a heat exchanger for an engine, the connector having a main body generally in the shape of a tube with a bend therein, the connector being arranged to be connected at its inlet end to a face of a heat exchanger and the connector including a support extending from the outlet end of the connector or adjacent thereto to support the end of the connector on the said face of the heat exchanger.
The free end of the support preferably defines a surface which is parallel to the plane of a connection surface at the inlet end of the connector.
The support may comprise a web across the main body of the connector. Thus, the main body of the connector may comprise two arms with the bend between them and the support may comprise a web connected to both arms and spanning the angle between them. The web may be a continuous web. The web may be in the form of a rib which may be of constant thickness.
According to a further aspect of the invention there is provided a method of making a connector according to either of the preceding aspects of the invention, the method comprising forging a blank and machining a bore therethrough.
Preferably the blank is drop forged.
The method preferably further comprises machining at least one connection surface of the connector. Where the support is part of the connector, the method preferably further comprises machining the connection surface of the support.
According to another aspect of the invention there is provided a method of attaching a connector according to the second or third aspects of the invention or a connector made by the method of the fourth aspect of the invention to a heat exchanger, the method comprising push fitting the connector to the heat exchanger so that the support is in contact with a surface of the heat exchanger, then heating the assembly to form a brazed joint between the main body of the connector and the heat exchanger and between the support and the heat exchanger.
According to another aspect of the invention there is provided a method of making the combination according to the first aspect of the invention, the method comprising push fitting the connector to the heat exchanger so that the support is in contact with the outlet end of the main body of the connector or adjacent thereto and is in contact with the face of the heat exchanger, then heating the assembly to form a brazed joint between at least the main body of the connector and the heat exchanger.
In this method, the bend in the heat exchanger means that its centre of gravity is offset, and hence, when the assembly is heated to form the brazed joint, the mechanical connection from the push fit may be insufficient to hold the connector in place and it may droop under gravity, but by means of the invention, the support props the connector in place to prevent any such droop. The method also increases the surface area to be brazed, which increases the strength of the brazed joint, and also increases the distance across which brazing takes place on the heat exchanger, which allows the connector to resist leverage forces better, for example from a spanner tightening a hose connection to the outlet end of the connector.
Where the support is part of the heat exchanger, the method may comprise the step of bending a tongue of material from a sheet forming a face of the heat exchanger so that the tongue stands up from the face of the heat exchanger to form the support.
Embodiments of the invention will now be described by way of example and with reference to the accompanying drawings, in which: Fig. 1 is a perspective view of a connector in a first embodiment of the invention; Fig. 2 is an end elevation of the connector of Fig. 1; Fig. 3 is a side elevation of the connector of Fig. 1 showing internal surfaces in phantom; Fig. 4 is a perspective view of the connector of Fig. 1 on a heat exchanger; Fig. 5 is a side elevation in cross section of the connector on a heat exchanger; Fig.. 6 is a perspective view of a connector in a second embodiment of the invention; Fig. 7 is an end elevation of the connector of Fig. 6; Fig. 8 is a side elevation of the connector of Fig. 6 showing internal surfaces in phantom; Fig. 9 is a perspective view of the connector of Fig. 6 on a heat exchanger including threaded adapter; Fig. 10 is a side elevation of the connector on a heat exchanger including threaded adapter; Fig. 11 is a perspective view of the connector and heat exchanger in a third embodiment; and, Fig. 12 is another perspective view of the connector and heat exchanger of Fig. 11.
Fig. 1 shows the connector 10 in the first embodiment of the invention. The connector 10 comprises a main body 12 in the form of a tube with a right angle bend in it. The main body thus comprises an arm 14 leading from the inlet end 16 to the bend 18, and a second arm 20 leading from the bend 18 to the outlet end 22.
At the inlet end 16, the outer surface of the main body 12 defines a first shoulder 24 leading to a narrower diameter section 26 and defining a downwardly facing surface 28 at the shoulder 24. The narrower diameter section 26 leads to a further shoulder 30 to a narrower diameter end section 32, the shoulder 30 defining a downwardly facing annular area 34.
A constant thickness rib 40 spans the two arms 14, 20. Thus, the rib 40 extends radially from the two arms 14, 20 of the main body 12 of the connector 10. The lower surface 42 of the rib 40 forms a continuation of the downwardly facing surface 28 at the outlet end 16 of the connector. The rib 40 is substantially rectangular and defines an upright end face 44 adjacent the outlet end 22 of the main body 12 of the connector 10.
As seen in Fig. 3, a bore 50 runs through the main body 12 of the connector 10. The bore is in two parts, a first bore 52 leading from the inlet end 16 of the main body 12 of the connector 10 to the bend 18, and a second bore 54 at right angles to the first bore 52 and intersecting the first bore 52 at the bend 18. The second bore 54 is wider than the first bore 52 where it meets the first bore 52 and widens in three sections 56, 58, 60 to reach the outlet end 22 of the connector 10.
The connector 10 is made by drop forging. Thus, a slug of metal is drop forged and the bores, 52, 54 are then machined into the forged part to form the through bore 50. The downwardly facing flat surfaces 28, 42, 34 are also machined flat, so that they are in a plane perpendicular to the axis of the first bore 52.
Figures 4 and 5 show a plate 70 defining the top face of a heat exchanger 72 which is a high pressure oil cooler for example for a large automotive vehicle. The upper surface of the sheet 70 is on two levels, a lower level 74 towards the end of the oil cooler and an upper level 76. A round aperture 78 is defined in the lower level 74 part of the sheet 70.
In use, the bottom section 32 of the connector 10 is pushed into the aperture 78 in the heat exchanger plate 70 so that the annular surface 34 lies on and in contact with the lower section 74 of the upper surface of the heat exchanger sheet 70, and lower flat surface 42 of the support rib 40 lies on and in contact with the higher part 76 of the upper surface of the heat exchanger sheet 70. The upper surface of the heat exchanger sheet 70 and/or the contacting surfaces 32, 34, 42 of the connector 10 are coated with brazing cladding material. On heating of this assembly to braze it, the cladding material will melt and on solidification join the connector 10 to the heat exchanger 72.
Without the rib 40, when the assembly is heated for brazing and the cladding material melts, the horizontal arm 20 of the main body 12 of the connector 10 can droop down towards the higher section 76 of the upper surface of the heat exchanger sheet 70. The rib 40 prevents this from happening. It is also seen that about half of the lower surface 42 of the rib 40 is in contact with the higher section 76 of the heat exchanger sheet 70 and a brazed joint is formed in that area. This significantly increases the area of the brazed joint between the connector 10 and the heat exchanger 70, which otherwise would just consist of the surfaces 32, 34 at the inlet end 16 of the connector 10. The connector 10 is therefore more strongly and robustly connected to the heat exchanger 72.
Figures 6 to 10 show a second embodiment of the invention. Only the differences from the first embodiment will be described. The same reference numerals will be used for equivalent features.
In the connector 10 of the second embodiment, the horizontal arm 20 is short and in the horizontal bore 54 only the first widened portion 56 is present.
In this embodiment, as shown in Figures 9 and 10, a threaded adapter 80 is attached to the outlet end of the connector 10. The adapter 80 includes a hexagonal section 82 to receive a spanner for tightening.
In use, although the rib 40 is not as long, it still is long enough to overlap and connect to the higher section 76 of the upper surface of the heat exchanger sheet 70. Where a spanner on the hexagonal section 82 of the adapter 80 exerts a force downwards, the rib will support the outlet end 22 of the connector 10 against downwards force through the adapter 80 from the spanner on the hexagonal section 82 by acting between the end 22 of the connector 10 and the surface of the higher section 76 of the heat exchanger sheet 70. Where a spanner on the hexagonal section 82 of the adapter 80 results in an upwards force on the outlet end 22 of the connector 10, the rib 40 will resist this as well through its brazed connection at its lower surface 42 on to the higher section 76 of the upper surface of the heat exchanger sheet 70. It will be seen that without the connection through the rib 40, the leverage to be exerted on the joint at the inlet end of the connector would be considerably greater.
A third embodiment of the invention is shown in Figs. 11 and 12. Only the differences from the first embodiment will be described. The same reference numerals will be used for equivalent features.
In the third embodiment, the rib 40 is not provided. Instead, a portion 90 of the higher level of the heat exchanger sheet 70 is bent upwards from adjacent the junction between the two levels 74, 76 to form a tongue 92, the upper surface 94 of which is in contact with the under surface 96 of the horizontal arm 20 of the main body 12 of the connector 10.
In this way, the tongue 92 supports the outlet end 22 of the connector 10 against drooping during brazing and also acts to resist downwards forces in use on the outlet end 22 of the connector 10. The upwardly facing surface 94 of the tongue 92 can be brazed to the under surface 96 of the horizontal arm 20 of the connector 10 so that the tongue 92 can resist upwards forces on the outlet end 22 of the connector 10 as well.
It is seen that by making the connector 10 by drop forging, a connector with a generally tube shaped main body 12 can be made which is efficient in the amount of material used to make the part. The presence of the rib 40 in the first and second embodiments and the tongue 92 in the third embodiment overcomes the problem of drooping during brazing and also provides extra strength to resist upwards and downwards forces on the horizontal arm 20 of the connector 10.
