Description
- The present invention relates to a heat exchanger assembly, in particular to a heat exchanger assembly provided with a bottle having a connector.
- Heat exchangers, in particular condensers, are provided with a receiver drier to act as reservoir to the refrigerant flowing therein. The receiver drier is installed between the condenser and an expansion valve of the air conditioning system to temporarily store the liquid refrigerant flowing from the condenser so that the required amount can be supplied to the evaporator according to the cooling load. In addition, at the same time, the receiver drier filters the refrigerant to remove water or foreign substances contained in the refrigerant. The receiver drier may include a cylindrical housing with an inlet connector and an outlet connector. The inlet connector of the receiver drier is fluidically coupled to the outlet of the condenser core to receive refrigerant therefrom. The outlet connector of the receiver drier is fluidically coupled to the inlet of the expansion valve or any other customer interface to deliver the refrigerant in liquid phase through a conduit fluidically connected to the outlet connector. It may also return the refrigerant to a different portion of the condenser core for subcooling.
- Generally, the receiver drier is formed as a separate unit from the inlet connector and the outlet connector. Further, the receiver drier is to be placed downstream of the condenser and upstream of the expansion device. The inlet connector and the outlet connector need to be assembled to the receiver drier and connected to the respective conduits of the condenser and the expansion valve. In such a situation, the packaging space is increased by an amount at least that of the space occupied by the receiver drier. It is also necessary to secure the receiver drier to the vehicle body in such a manner that it is sufficiently durable against vibration independent of the condenser. Further, multiple components are required to connect the receiver drier with the condenser core and the expansion valve. Furthermore, manufacturing of component required for assembly, and assembly work of the connectors to the receiver drier eventually increase the cost of the vehicle air-conditioner.
- Accordingly, there remains a need for a receiver drier with an integral connector that mitigates spacing constrains and reduces number of components required for installation of the receiver drier.
- In the present description, some elements or parameters may be indexed, such as a first element and a second element. In this case, unless stated otherwise, this indexation is only meant to differentiate and name elements, which are similar but not identical. No idea of priority should be inferred from such indexation, as these terms may be switched without betraying the invention. Additionally, this indexation does not imply any order in mounting or use of the elements of the invention.
- In view of the foregoing, an embodiment of the invention herein provides a heat exchanger assembly comprising a plate heat exchanger and a bottle with a connector. The connector comprises an inlet and an outlet. The inlet is directly connected to the heat exchanger and configured for supplying the heat exchange medium to the bottle. The outlet is configured as an outlet of the heat exchanger assembly. The bottle comprises a tubular section forming the bottle volume and a closing section for closing the bottle volume. The connector is integrally formed with the closing section. In one embodiment, the tubular section and the closing section are connected to each other by means of welding or brazing.
- The inlet and the outlet are fluidically connected to at least one channel formed within the bottle.
- In one embodiment, the inlet and the outlet are formed on the opposite sides of the connector. In another embodiment, the inlet and the outlet are formed on the same side of the connector.
- In one embodiment, the inlet and outlet are co-axial. In one embodiment, the inlet is arranged parallel to the stacking direction of the plate heat exchanger. In one embodiment, the outlet is arranged parallel to the stacking direction of the plate heat exchanger. In one embodiment, the inlet of the bottle is directly attached to a terminal plate of the plate heat exchanger.
