Description

AREA

[0001] The registration refers to a soldered connection arrangement. BACKGROUND

[0002] A stacked plate heat exchanger is constructed from a plurality of heat exchanger plates stacked on top of each other. The plurality of plates defines a flow channel for a first fluid, which in one embodiment, by way of example and without limitation, is machine oil, if the heat exchanger is, for example, an engine oil cooler (EOC). Each of the plurality of plates has at least one pair of openings aligned with each other within the plurality of plates, forming part of the inlet and outlet connections of the heat exchanger. The inlet and outlet connections each have an inlet and an outlet, allowing the first fluid to flow from the inlet through the flow channels (provided by the plurality of plates) to the outlet, where it exits. Various types of stacked plate heat exchangers are known in the prior art.

[0003] Typically, the inlet and outlet accommodate a fitting to which a hose or other pipe can be attached. A method for attaching a fitting to the heat exchanger is described in Fig. Figure 1 shows a cross-sectional view of a connector having a flange brazed to the reinforcement plate. One of the challenges with such a connector arrangement is ensuring the connector is properly aligned with the openings in the reinforcement and cover plates. Slippage or sliding of the connector can occur, resulting in an improperly aligned connector. Additionally, a plating material must be provided on both sides of the reinforcement plate for brazing to form the connector arrangement.

[0004] To address some of the issues associated with the connection arrangement after Fig. To counteract the associated disadvantages, alternative connection arrangements can be used, as in the Fig. 2 and Fig. 3 shown.

[0005] In the connection arrangement according to Fig. 2 is the connector with a flange, similar to the one shown below. Fig. 1. However, the flange is not located at the end of the fitting, but rather is positioned so that the flange rests against the heat exchanger's reinforcement plate, with part of the fitting extending beneath the reinforcement plate and the heat exchanger's cover plate. This portion of the fitting extending beneath the cover plate is subjected to a crimping or upsetting operation to form an edge, clamping the reinforcement plate and cover plate between the flange and the edge to secure the fitting to the heat exchanger and form the connection assembly.

[0006] Fig. Figure 3 shows another example of the connection arrangement used to attach the fitting to the heat exchanger. The difference between the connection arrangements according to Fig. 2 and Fig. 3 is that the connecting piece after Fig. 2. The connector has a pre-formed wide bead. A tool is inserted from the bottom end of the connector to expand the wall of the connector outwards and secure it to the reinforcement plate and the cover plate. The process of expanding from the inside is called 'staking'. A crimping or compression operation can also be performed on the bottom of the connector to form a rim (similar to the connector described in [reference]). Fig. 2) for attaching the connector to the reinforcement plate and the cover plate.

[0007] In the connection arrangements described above, a plating material is provided between the reinforcement plate and the cover plate of the heat exchanger. Additionally, a plating material is also provided on the top side of the reinforcement plate and is therefore present on both sides of the reinforcement plate. During a soldering process, the plating material, which acts as a filler, helps to bond the reinforcement plate to the cover plate, to bond the connection piece to the heat exchanger, and to fill any gaps. Since plating material can be expensive, there is a need in the prior art to reduce its use. Therefore, there is also a need in the prior art for a heat exchanger arrangement in which the plating material is present on one side of the reinforcement plate, rather than on both sides.

[0008] In addition to the above, one of the challenges associated with the connection arrangements described above is the precise alignment of the fitting with the heat exchanger. Furthermore, care should be taken during the coupling process to ensure that the fitting is positioned correctly within the heat exchanger, avoiding unnecessary angular movement. Therefore, there is a need in the prior art for a connection arrangement that helps ensure precise positioning of the fitting, and preferably, for the fitting to be self-positioning. There is also a need in the prior art for a connection arrangement that helps prevent unnecessary angular movement of the fitting during the connection process. SUMMARY OF THE INVENTION
