Abstract

improved design in connection with multiport extrusions (MPE) in heat exchangers (1) for heat exchange or heat recovery in solutions such as refrigeration or heat pump systems, in particular condensers or evaporators in such systems. The MPE multiport extrusion (7) is a Web-like extrusion (Web-MPE) with "individual" tubes or micro-channels (8) interconnected with thinner flanges or webs (9).

Description

Multiport extrusion (MPE) design
The invention is a divisional application of the Chinese invention patent 'multiport extrusion part (MPE) design' with the application date of 2014, 01, 30 and the application number of 201480024808.1.
Technical Field
The present invention relates to a new design related to multiport extrusions, so called MPE, used in exchangers for heat exchange or heat recovery, in particular condensers or evaporators, in such systems, in solutions such as refrigeration or heat pump systems.
Background
microchannel type heat exchangers based on aluminium multiport extruded profiles are known, in which fins, also of aluminium, are provided between the extruded tubes or channels.
this type of heat exchanger is known, for example, from JP publication No. 3-13794.
A drawback of these known heat exchangers is poor drainage of the condensed water on the outer surface of the heat exchanger. Another drawback is the relatively fixed surface balance between the refrigerant side and the air side of the heat exchanger (lack of optimization possibilities). With the trend towards the use of higher pressure refrigerants, the need for fewer ports in the extruded profile on the refrigerant side of the heat exchanger arises and represents one method of achieving this "surface balance" with known heat exchangers.
Disclosure of Invention
the present invention provides an improved MPE design wherein:
The benefits of using MPE production techniques;
Allowing better surface balance (optimization) between the refrigerant side and the air side of the heat exchanger;
-improved drainage of condensed water from MPE-type heat exchangers.
the invention is characterized by the features as defined in the appended independent claim 1.
Preferred embodiments of the invention are further defined in the independent claims 2-4.
Drawings
The invention will be described in further detail below, by way of example, with reference to the accompanying drawings, in which:
Figure 1 shows a perspective view of a portion of a generally known MPE-based heat exchanger with a serpentine fin assembly,
Figure 2 shows a perspective view of a known MPE of the standard type and a part of the MPE design according to the invention,
Figure 3 shows an example of an improved Web-MPE according to the invention,
Figure 4 shows an expanded view of the assembly of a portion of a Web-MPE based heat exchanger with a serpentine fin assembly,
Figure 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 depressions,
Fig. 7 shows an alternative application of the invention in which the tube is gathered, bent or twisted.
Detailed Description
as mentioned above, figure 1 shows, by way of example and in perspective, a portion of a generally known MPE-based heat exchanger with a serpentine fin assembly 1. As can be seen from the drawings, the serpentine fins 2 of the heat exchanger are in this case provided lengthwise, standing between the multi-tube extrusions 3, 4 and are attached to the extrusions at their tops or outer surfaces of the bends 5 with brazes 6. This type of heat exchanger usually consists of several such extrusions with a "layer" of fins 2 and a "layer" of extrusions 3, 4 (one on top of the other), depending on the size and heat exchange capacity of the heat exchanger.
Figure 2 shows a section of two extruded profiles, where the upper profile (for comparison) is a standard type MPE 3, 4 of the type shown in figure 1, and the lower profile 7 is a new MPE design according to the invention. This new design is also of the multi-port type but is a Web-like extrusion with "individual" tubes or microchannels 8 interconnected with thinner flanges or webs 9, referred to below as a Web-MPE design or type.
Figure 3 shows an example of a Web-MPE design 10 according to the invention and the flexibility of such a design. As can be seen from the figures, removing a portion of the flange or web 11 results in a particular web pattern. The material may be removed, for example, by roller punching. This novel design provides the following advantages:
-the openings in the Web give the Web-MPE water drainage performance characteristics equivalent to that of a tube in a fin-and-tube heat exchanger;
the web offers the possibility of a flexible design in the ratio between the surface on the refrigerant side and the surface on the air side;
the Web-MPE also provides additional flexibility regarding the shaping (bending and twisting) of the profile (explained further below).
figure 4 shows an expanded view of an assembly of a portion of a heat exchanger with a serpentine fin 13 assembly and including a manifold 15 based on Web-MPE 12. This type of heat exchanger is normally provided with two manifolds 15, an inlet manifold and an outlet manifold, and this is therefore only an illustration showing only one manifold 15. Figure 4 also shows the direction of the refrigerant flowing into the Web-MPE microport or tube 14 and the direction of the air flowing in the transverse direction of the Web-MPE12 but alongside the serpentine fins 13 on the outside of the heat exchanger accordingly with arrows.
figure 5 further illustrates an embodiment of a Web-MPE design according to the invention where the tube or port of the Web-MPE extrusion 16 is provided with a flange or Web 17. This Web-MPE has a cross-sectional 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 of conventional arrangement and their tops are provided with depressions 19 to obtain improved drainage.
figure 7 shows a different design of a Web-MPE according to the invention. The web material between the tubes 20 of the MPE extrusion 10 is removed over a length 21 and the tubes are then gathered as shown in the drawing. This improvement further enables the tubes to be twisted or bent for different applications, as shown in the examples in the following figures, which show that tubes a, b and c can be twisted or bent, for example, 180 degrees to suit different refrigeration applications.
In case a higher pressure refrigerant is used, 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 the invention it is possible to control and balance the heat transfer in the heat exchanger, e.g. between the air side and the refrigerant side of a heat pump system or a refrigeration system. This is done by controlling the distance or spacing between the ports or tubes of the Web-MPE and/or by removing more or less Web material.
With the Web-MPE according to the invention, an improved drainage of the condensate water on the air side of the heat exchanger is also obtained, due to the openings in the Web.
The invention as defined in the claims is not limited to the examples as described above and shown in the drawings. Thus, the heat exchanger may be used not only as a condenser or evaporator in a refrigeration system, but in any system where heat is exchanged or recovered with air or other fluid.
