Figure 1 shows a detailed perspective view of anelongated tubing element 10 having a plurality ofmicrochannels 90 with quadrangular cross-section. - The tubing element is a rigid elongated heat exchanger tubing having at least a
first end 20 and asecond end 30 and having afirst side wall 40 andsecond side wall 50. Thefirst side wall 40 and thesecond side wall 50 are arranged substantially parallel to each other and the distance d between thefirst side wall 40 and thesecond side wall 50 is considerably smaller than the width W of thefirst side wall 40 and thesecond side wall 50. Thus, the tubing element has a substantially overall flat tubing structure. - The width W of the
first side wall 40 and thesecond side wall 50 is approximately at least ten times larger than the distance d between thefirst side wall 40. Thesecond side wall 50 and the first side wall and thesecond side wall rounded connection wall 45, 55. - The width W of the
first side wall 40 and thesecond side wall 50 is equal and chosen within a range of about 10 mm to 30 mm. - In the embodiment shown in
Figure 1 , the width W of the first side wall and thesecond side wall - Normally, the distance between the
first side wall 40 and thesecond side wall 50 is chosen respectively to the width values of thefirst side wall 40 and thesecond side wall 50, i.e. normally within a range of about 1 mm to 3 mm. - The
tubing element 10 is at least partially tilted and sloped and also at least partially helically wound and twisted as shown inFigure 2a so as to form at least a part of a helical structure (seeFigure 3 ), whereby the helical structure has an overall cylindrical structure and the helical structure is formed in a cylindrical shape. - As best seen in
Figure 3 , thetubing element 10 is forming an overall cylindrical structure having a central longitudinal axis X and thetubing element 10 is spatially curved around the central longitudinal axis X and interleaved in the structure (seeFigure 4 ) of severalequal tubing elements 10. Thetubing elements 10 have a plurality offins 60 on bothouter surfaces first side wall 40 and thesecond side wall 50, as can be seen inFigure 1 ,2a and3 . - The
fins 60 are arranged between the coveringwalls outer surfaces first side wall 40 and thesecond side wall 50. Moreover, the coveringwall outer surfaces first side wall 40 and thesecond side wall 50 are substantially parallel. However, the coveringwall outer surfaces first side wall 40 and thesecond side wall 50 are not directly connected to each other so that e.g. a cooling medium may flow through thefins 60 arranged within the space provided by the coveringwall outer surfaces first side wall 40 and thesecond side wall 50. - In particular, the cooling medium may enter the space also from the sides of the
rounded connection walls 45, 55. In the embodiment shown inFigs. 1 to 4 , thefins 60 are perpendicularly arranged on theouter surfaces first side wall 40 and thesecond side wall 50. - Alternatively, it is possible that the
fins 60 are inclined arranged on theouter surfaces first side wall 40 and thesecond side wall 50, whereby exemplarily the angle between thefin 60 and theouter surface - The
fins 60 merely extend along the whole width of theouter surfaces first side wall 40 and thesecond side wall 50 and are curved. Furthermore, thefins 60 are arranged along a curve extending along the whole width of theouter surfaces first side wall 40 and thesecond side wall 50. Moreover, between thefins 60several gaps 62 are provided. Through thegaps 62 the medium, e.g. a cooling or heating medium may pass. - The
fins 60 and the curve offin 60 and theconnection walls 45, 55 are arranged such to each other that they enclose an angle γ. The angle γ is chosen in the embodiment shown inFigs. 1 to 4 within a range about 30° to about 60°, here in an angle of about 45°. - An angle of about 45° between the
fins 60 and the curve offins 60 and at least one of theconnection walls 45, 55 is considered to be substantially neutral, in particular as a neutral arrangement with respect to the interference with e.g. fans or the like, which may be connected or used together with the heat exchanger means 100 comprisingsuch tubing elements 10, as e.g. shown inFigures 4 ,9 and10 . -
Figure 2b shows an alternative embodiment of a tubing element 10', which is almost identical with the embodiment shown inFigure 2a . The only difference is that the tubing element 10' comprises fins 60' which merely extend along the whole width W of theouter surfaces first side wall 40 and thesecond sidewall 50. - As can be seen in
Figure 3 , thetubing elements 10 are tilted and sloped and helical wound and twisted so as to form a part of a helical structure, whereby this helical structure has an overall cylindrical structure. - These tubing elements are interleaved and arranged one upon the other to a heat exchanger means 100, as shown in
Figure 4 . Also, the central longitudinal axis is shown. -
Figure 5 shows a non-sloped and unwound rigid elongatedtubing element 10 forheat exchanger 100 according to the present invention. Thetubing element 10 has the same structural and functional features as described with respect to thetubing element 10 shown inFigure 1 to 4 . - Moreover, the
tubing element 10 comprises at itsfirst end 20 and at its second end 30 a collectingportion first side wall 40 and thesecond side wall 50 to a smaller width. - The collecting
portions tubular elements tubing element 10 may be connected with another tubing element or any connecting means, e.g. the first and second connectingmeans Figure 7 ,8 ,9 and10 . -
Figure 6 shows atubing element 10 according toFigure 5 , whereby thetubing element 10 shown inFig. 6 has been partially tilted and sloped and partially helically wound and twisted so as to form at least a part of a helical structure. - After the at least partially tilting and sloping and the at least partially helically winding and twisting as described in connection with
Figure 6 , the so formed rigidelongated tubing elements 10 for the heat exchanging means 100 may be attached to another, equally formedfurther tubing element 10. Bothtubing elements 10 are connected by a first connectingmeans 25. This connecting means 25 is aconnector tubing element 25, which is U-shaped bended, seeFigure 7 . -
Figure 8 is another perspective view of the arrangement of tubing elements as shown inFigure 7 . - The so
connected tubing elements 10 may be further combined to an overall cylindrical structure of a heat exchanger means 100, as shown inFigure 9 and10 . As can be seen inFigure 9 and10 , thesecond end 30 ofadjacent tubing elements 10 are connected by a second connectingmeans 35. Also, the central longitudinal axis is shown inFigure 9 . - The second connecting
means 35 comprises a plurality ofconnected tubing elements 36 and acentral connector portion 37, whereby theconnector tubing elements 36 and thecentral connector portion 37 are arranged in a star-shaped manner. - The
connector tubing element 36 form alternatingly an inlet or an outlet. The inletconnector tubing elements 36 are connected with theinlet portion 38 of thecentral connector portion 37 and the outletconnector tubing elements 36 are connected with theoutlet portion 39 of thecentral connector portion 38. In any case, inlet and outlet function may be interchanged, i.e. the inlet may be the outlet or vice versa.
