DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a device equipped with flanges, by means of which an exchange of cold and heat can be effected by a surrounding medium, a procedure for the manufacture of said device and the area of its application.
The principal object of the present invention is to provide a device of the kind mentioned above, which for one thing is easy to manufacture, so that it lends itself to be made by extrusion, and for another thing is simple and effective in use, as in addition to having great surfaces of its flanges it does not require complicated and expensive working operations and moreover can find varying applications within a great number of areas.
Said object is obtained by means of a device designed according to the present invention, which is substantially characterized by the flanges being supported by a core located at the center of the device and extending in the longitudinal direction of the same, said flanges extending in outward direction as counted from said core and having a shape extending in the longitudinal direction of said core.
An example of embodiment of the invention will be described in the following, reference being made to the accompanying drawings, in which
FIG. 1 is a view of a vertical cross-section through the wall of a refrigerator with the refrigeration unit mounted therein, said unit being among other things formed by two devices according to the invention, which have been coupled together,
FIG. 2 is a cross-sectional view of the device,
FIG. 3 is a cross-sectional view of an enlarged scale of a portion of the device,
FIG. 4 is a cross-sectional view on an enlarged scale of a portion of a cooling and heating flange of the device,
FIG. 5 is a cross-sectional view of an enlarged scale of an external flange portion of the device,
FIG. 6 is a cross-sectional view on an enlarged scale of a fastening means of the device,
FIG. 7 is a view of a vertical cross-section of an additional example of embodiment of the application of the device in a refrigerator,
FIG. 8 is a view of a vertical cross-section through the device according to FIG. 1,
FIG. 9 is a view of a vertical cross-section through the device according to FIG. 7, and
FIG. 10 is likewise a view of a cross-section through the device according to FIG. 7 but along another plane than the one illustrated in FIG. 9.
A device for the exchange of cold and heat is in the FIGS. 1-10 indicated with 1, and a core located at the center of said device and extending in the longitudinal direction of the same is indicated with 2. Flanges indicated with 3 extend from said core 2 in outwards direction and have a shape of long extension in the longitudinal direction of said core 2 and the device 1. The core 2 has a substantially rectangular cross-section, preferably one of square form, and as is clearly evident from FIG. 2, it is provided with legs 4, which in outwards direction project from the center of the core 2, said legs likewise having a long extension in the longitudinal direction of the device 1. Most of said flanges 3 are supported by these legs 4 and are placed in a substantially parallel arrangement in relation to each other between two adjacent legs 4, which is also the case with flanges 5 projecting from the core 2 in the same direction.
In order to increase the contact surface of the flanges 3, 5 their laterally extending sides are provided with zig-zag formed surfaces 6 in angular arrangement, but these surfaces can of course also exhibit another design, as for example a wave form or a stepped shape.
There are two fastening means 7 each one located on its side of diametrically opposed sides of the central axis of the core 2, said means in the illustrated embodiment comprising one clasping portion 7, but it can of course be designed in a different manner and be provided with more than two fastening units. Four fastening means located right in front of each other can for example be provided on the core 2. Fastening means 8 similar to the ones just described are located at the end of each one of the four legs 4 projec
