Abstract

Improved design related to Multi Port Extrusions (MPE) used in exchangers (1) for heat exchange or heat recovery in solutions such as refrigeration or heat pump systems, in particular a condenser or evaporator in such systems. The MPE multiport extrusion (7) is a web like extrusion (Web-MPE) with "individual" tubes or micro channels (8) interlinked with thinner flanges or webs (9).

Description

Multi Port Extrusion (MPE) design
The present invention concerns a new design related to Multi Port Extrusions so-called MPE, used in exchangers for heat exchange or heat recovery in solutions such as refrigeration or heat pump systems, in particular a condenser or evaporator in such systems.
Micro channel type type heat exchangers based on multiport extruded profiles of aluminium are known where fins, also of aluminium, are provided between the extruded tubes or channels.
Heat exchangers of such type are for instance known from JP laid open publication No. 3-13794
A limitation with these known heat exchangers is the poor drainage of water condensed on the outer faces of the heat exchanger. Another limitation is the relatively fixed surface balance (lack of optimization possibilities) between the refrigerant and air side of the heat exchanger. With the trend towards use of more high pressure refrigerants the need for fewer ports in the extruded profile on the refrigerant side of the heat exchanger arises and represents a means to obtain such "surface balance" with the known heat exchangers. With the present invention is provided an improved MPE design which:
- Utilize the benefit of MPE production technology
- Allows better surface balance (optimization) between the refrigerant and air side of the heat exchanger.
- Improves condensed water drainage from the MPE type heat exchanger.
The invention is characterized by the features as defined in the attached independent claim"! . Preferred embodiments of the invention are further defined in the independent claims 2 - 4.
The invention will be further described in detail in the following by means of examples and with reference to the attached drawings, where:
Fig. 1 shows in perspective view part of a commonly known MPE based heat exchanger with serpentine fin assembly,
Fig. 2 shows a perspective view part of a standard type, known MPE and MPE design according to the invention,
Fig. 3 shows an example of a modified Web-MPE according to the present invention, Fig. 4 shows an expanded view of an assembly of a part of a Web-MPE based heat exchanger with a serpentine fin assembly,
Fig. 5 shows an embodiment of a Web-MPE design according to the invention, Fig. 6 shows an alternative application of the invention in a heat exchanger where the serpentine fins are provided with excavations,
Fig. 7 shows an alternative application of the invention where the tubes are gathered, bent or twisted.
As stated above, Fig. 1 shows as an example and in perspective view part of a commonly known MPE based heat exchanger with serpentine fin assembly 1. As can be seen from the figure, the serpentine fin 2 of the heat exchanger is in this case provided in the longitudinal direction standing between the multi tube extrusions 3, 4 and is attached to the extrusions at their crests or bends 5 outer faces by means of the brazing 6. A heat exchanger of this type is normally composed of a number of such extrusions, with "layers" of fins 2 and extrusions 3, 4 (one above the other), depending on the size and heat exchange capacity of the heat exchanger.
Fig. 2 shows parts of two extruded profile where the upper profile (for comparison) is the standard type MPE 3, 4 of the type shown in Fig. 1 , while the lower profile 7 is the new MPE design according to the invention. This new design is also a multiport type, but a web like extrusion with "individual" tubes or micro channels 8 interlinked with thinner flanges or webs 9, in the following called Web-MPE design or type. Fig. 3 shows an example of a Web-MPE design 10 according to the invention and the flexibility of such design. As can be seen from the figure parts of the flanges or webs 1 1 are removed creating a specific web pattern. The material may for instance be removed by roller punching. This novel design provides advantages: · The openings in the web gives the Web-MPE drainage performance characteristics equal to tubes in a fin and tube heat exchanger
• The web gives the possibility to a flexible design of the ratio between the surface of the refrigerant and the air side
• The Web-MPE also provides additional flexibility regarding formability (bending and twisting) of the profiles (further explained below).
Fig. 4 shows an expanded view of an assembly of a part of a Web-MPE 12 based heat exchanger with a serpentine fin 13 assembly and including a manifold 15. Heat exchangers of this type is commonly provided with two manifolds 15, an inlet manifold and outlet manifold and this is therefore just an illustration showing only one manifold 15. Fig. 4 also shows by means of arrows the direction of the refrigerant flowing in the Web-MPE micro ports or tubes 14, respectively the direction of the air flowing on the outside of the heat-exchanger in the transversal direction of the Web-MPE 12 but alongside the serpentine fins 13. Fig. 5 further shows an embodiment of a Web-MPE design according to the invention where the tubes or ports of the Web-MPE extrusion 16 is provided with flanges or webs 17. This Web-MPE has a cross section design with good extrusion and brazing characteristics.
Fig. 6 shows an alternative application of the invention in a heat exchanger where the serpentine fins 18 are traditional laying and provided with excavations 19 at their crests to achieve a improved water drainability.
Fig. 7 illustrates different designs of the Web-MPE according to the invention. The material of the web between the tubes 20 of the MPE extrusion 10 is removed over some length 21 and the tubes are then gathered as shown in the figure. This modification further makes it possible to twist or bend the tubes for different applications as is illustrated in the examples in the figure below where is shown that the tubes a, b and c may be twisted or bent for instance 180° to be adapted to different refrigeration applications..
With higher pressure refrigerants the ratio between the surface in contact with the refrigerant and the surface in contact with the air becomes even more unbalanced.
With the Web-MPE according to present invention it is possible to control and balance the heat transfer in a heat exchanger such as between the air side and refrigerant side of a heat pump or refrigeration system. This is done by controlling the distance or space between the ports or tubes of the Web-MPE and/or removing more or less of the web material.
With the Web-MPE according to the invention improved drainage of water condensing on the air side of heat exchanger is also obtained due to the openings in the web.
The invention as defined in the claims is not delimited to the example as described above and shown in the figures. Thus, the heat exchanger can be used, not only as condenser or evaporator in a refrigeration system, but in any system where heat is exchanged or recovered by means of air or other fluid.
