[0073] FIG. 12: shows a cross section through another container according to the invention.

[0074] FIG. 1 shows a heat exchanger 1 according to the invention having a heat exchanger tube 2. Heat exchanger tube 2 serves to heat up, heat and/or evaporate a fluid, e.g. a liquid, surrounding heat exchanger tube 2.

[0075] Heat exchanger tube 2 comprises three tube sections 20, 21 and 22. A second tube section 21 connects a first tube section 20 and a third tube section 22 to each other. In this case, first tube section 20 and third tube section 22 are disposed parallel to each other.

[0076] Furthermore, a plurality of tubes 10 is shown. Tubes 10 penetrate heat exchanger tube 2, in particular first tube section 20 and third tube section 22, tubes 10 being spaced apart from each other. Tubes 10 are disposed helically in heat exchanger tube 2. Heat exchanger tube 2 has double the number of openings, which are diametrically disposed, based on the number of tubes 10, wherein each tube 10 is guided through two of these openings or extends through two of these openings. Tubes 10 are connected to heat exchanger tube 2 on both sides via their end tube sockets 11 and 12 in the area of the openings. The connection is fluid-tight. Individual tubes 10 are realized as hollow-cylindrical tubes.

[0077] By providing tubes 10 penetrating heat exchanger tube 2, the shell surface of the heat exchanger is considerably enlarged.

[0078] Furthermore, heat exchanger 1 has an attachment plate 14. Attachment plate 14 has two openings 15 and 16 for accommodating first tube section 20 and third tube section 22 of heat exchanger tube 2. In this case, heat exchanger 2 is realized in such a manner that first tube section 20 of heat exchanger tube 2 is guided through first opening 15 of attachment plate 14 and third tube section 22 of heat exchanger tube 2 is guided through second opening 16 of attachment plate 14. Attachment plate 14 is configured to insert and mount heat exchanger 1 into/in a heat exchanger device and/or an evaporation device.

[0079] First tube section 20 disposed at the top in the sheet plane can be understood as tube section on the combustion tube side. Third tube section 22 disposed at the bottom in the sheet plane can be understood as tube section on the fan side. The vertical tube section connecting the tube section on the combustion tube side to the tube section on the fan side can be understood as second tube section 21.

[0080] Second tube section 21 comprises an additional tube 10 which penetrates at least tube section 20 on the combustion tube side and tube section 22 on the fan side on the shell side and runs within second tube section 21. Like tubes 10, tube 10 is connected to heat exchanger tube 2 on both sides via its end tube sockets.

[0081] Moreover, heat exchanger 1 has a flange 17 provided with two openings. Flange 17 is disposed at the end of the two tube sections 20 and 22. Flange 17 is configured to connect a gas burner and a fan at heat exchanger 1. For this purpose, a gas burner attachment 18 and a fan attachment 19 are disposed on flange 17.

[0082] A conveying direction of air heated by means of a gas burner (not shown) is illustrated by arrow P1. A conveying direction of cooled air suctioned by means of a fan (not shown) is illustrated by arrow P2.

[0083] With heat exchanger 1 according to the invention, it is made possible to enlarge the surface of heat exchanger tube 2 outwardly due to the usage of tubes 10 penetrating heat exchanger tube 2. Thereby, it can be achieved that heated or hot air in heat exchanger tube 2 gets to tubes 10 and that the air experiences a swirl effect in this process.

[0084] The heat exchange is the greatest in the many tubes 10 since, there, the heat exchange is the most effective and an additional circulation occurs in the liquid surrounding heat exchanger 1. The air in the heat exchanger comes into contact with the shell surface of heat exchanger tube 2, which is enlarged due to the plurality of tubes 10, and transfers the heat into the liquid surrounding heat exchanger tube 2 of heat exchanger 1.

[0085] FIG. 2 shows a side view of heat exchanger 1, wherein also the areas of individual tubes 10 and 20 which are actually not visible are shown. Optionally, first and third tube sections 20 and 22 can further comprise connection tube sections 3 and 4 to allow first and third tube sections 20 and 22 to be attached to flange 17.

[0086] FIG. 3 shows a detail A of FIG. 2. As indicated above, heat exchanger tube 2 has double the number of openings 5 and 6, which are diametrically disposed, based on the number of tubes 10, wherein each tube 10 is guided through two of these openings 5 and 6. In this case, central longitudinal axes 13 of tubes 10 run orthogonally to central longitudinal axis 9 of heat exchanger tube 2. A diameter of tubes 10 corresponds to approximately of the diameter of heat exchanger tube 2. This results in intensified swirl effects of the air in heat exchanger tube 2 at tubes 10.

[0087] Furthermore, end tube sockets 11 and 12 of each tube 10 slightly project on both sides on heat exchanger tube 2. This allows a welded connection, a rolled connection or a pressed connection between end tube sockets 11 and 12 and heat exchanger tube 2 to be realized in an easy manner.

[0088] FIG. 4 shows a section A-A of FIG. 1. In an axial direction of heat exchanger tube 2, tubes 10 are offset relative to each other at an angle at approximately 20. This allows intensified swirl effects of the air in heat exchanger tube 2 to be achieved at tubes 10.

[0089] Central longitudinal axes 13 of tubes 10 intersect central longitudinal axis 9 of heat exchanger tube 2 at right angles.

[0090] FIG. 5 shows a bottom view of heat exchanger 1 according to the invention of FIG. 1, wherein also the areas of individual tubes 10 which are actually not visible are shown.

[0091] FIG. 6 shows a perspective illustration of an evaporation device 30 according to the invention. Evaporation device 30 has a housing 31 and a condenser 34. Housing 31 comprises at least one opening 32. Opening 32 serves to insert heat exchanger 1 into evaporation device 30 and to fix attachment plate 14 of heat exchanger 1 according to FIGS. 1 to 5 to housing 31. In housing 31 is a fluid to be evaporated, in particular a liquid.

[0092] Thus, heat exchanger 1 can be accommodated in housing 31 with its integrated attachment plate 14.

[0093] Evaporation device 30 is configured to convey vapor through at least one narrowed duct 33 into condenser 34. Said condenser 34 comprises a deflection plate which deflects the vapor to the side and condenses it as a result of a cooling process. The condensate produced in this process can be collected by respective channels 35 on either side of housing 31 and can be directed to a tube system 36. In this case, tube system 36 can be designed as a kind of siphon. Due to the design as siphon, a counter-pressure which intensifies the evaporation effect is generated in evaporation device 30.

[0094] In FIG. 7, a perspective illustration of a heat exchanger device 40 according to the invention is shown. Heat exchanger device 40 has a housing 41. Housing 41 comprises at least one opening 42. Opening 42 serves to insert heat exchanger 1 into heat exchanger device 40 and to fix attachment plate 14 of heat exchanger 1 according to FIGS. 1 to 5 to housing 41. In housing 41 is a fluid to be heated up and/or to be evaporated, in particular a liquid.

[0095] Heat exchanger device 40 is designed as a closed container in which heat exchanger 1 is mountable. When heat exchanger 1 is mounted, the waste heat can be directed again, for example, from evaporation device 30 through heat exchanger device 40 in order to, thus, preheat the liquid which is then to be directed into evaporation device 30.

[0096] In FIG. 8, a perspective illustration of an installation 50 according to the invention is shown. As shown, installation 50 comprises a frame or a stand 51 for accommodating an evaporation device 30 according to FIG. 6 and a heat exchanger device 40 according to FIG. 7. Evaporation device 30 comprises a gas burner 24 and a fan 25. Heat exchanger device 40 has two attachment sockets 43 and 44.

[0097] Installation 50 is designed in such a manner that evaporation device 30 and heat exchanger device 40 are disposed in frame/stand 51. Devices 30 and 40 can be stacked in any type of manner. The two devices 30 and 40 can be connected to conduits in order to pass on the liquid from heat exchanger device 40 to evaporation device 30.

[0098] Both evaporation device 30 and heat exchanger device 40 can be mounted in frame/stand 51 at a slope of approximately 1.5 so that condensed water produced in heat exchanger device 40 can run off.

[0099] Gas burner 24, fan 25 and attachment sockets 43 and 44 have been designed in such a manner that they each have the same attachment and, thus, can be mounted in installation 50 on flange 17 of heat exchanger 1 as needed.

[0100] In the case at hand, burner 24 and fan 25 were mounted on evaporation device 30. Furthermore, fan 25 was connected via attachment socket 43. As a result, the exhaust air heat is guided and/or pressed through heat exchanger device 40.

[0101] However, in the case at hand, it also would be possible to exchange fan 25 with attachment socket 43 and to connect the two attachment sockets 43 and 44. In this case, the exhaust air would also be drawn through heat exchanger device 40.

[0102] Advantageously, several heat exchanger devices 40 can be coupled to each other in order to achieve an improved heat output, for example.

[0103] FIG. 9 shows a container 100, in particular a water container. Container 100 comprises a housing 101 having a cover 102. Housing 101 is cylindrical and has a bottom. Furthermore, container 100 comprises a heat exchanger tube 2.

[0104] Heat exchanger tube 2 has several tube sections 20, 21, 22, 26, 27, 28 and 29. Tube sections 20, 21, 22, 26, 27, 28 and 29 of heat exchanger tube 2 are numbered consecutively in the conveying direction and/or flow direction (arrows P1 and P2).

[0105] Of tube sections 20, 21, 22, 26, 27, 28 and 29, four tube sections 20, 22, 27 and 29 are disposed parallel or coaxially to each other within the container with respect to a central longitudinal axis of container 100. Two tube sections 20 and 22 are connected to a tube section 21 which is realized as a 180 bend. Two tube sections 22 and 27 are connected to a tube section 26 which is realized as a 180 bend. Two tube sections 27 and 29 are connected to a tube section 28 which is realized as a 180 bend.

[0106] For the sake of clarity, FIG. 9 does not illustrate a water inlet and a water outlet. In FIG. 10, which is based on FIG. 9, water inlet 111 and water outlet 112 are shown.

[0107] In addition to cylindrical housing 101, container 100 comprises a cover 102 as shown in FIG. 11. For connecting cover 102 to housing 101 of container 100, a seal 103 and a screw connection 104 or the like are provided. Cover 102 has one attachment for gas burner 24 and one attachment for fan 25. Furthermore, cover 102 has a water inlet 111 and a water outlet 112. A flexible tube 105 can be disposed at water inlet 111. A flexible tube 106 can be disposed at water outlet 112.

[0108] The shape of heat exchanger tube 2 shown in FIG. 11 is actually not visible, but it has been included in the figure for better understanding.

[0109] Container 100 is configured to heat up or to heat water introduced or conveyed into container 100 via water inlet 111 by means of heat exchanger tube 2. In this process, the water having an initial temperature at water inlet 111 is conveyed in the flow direction according to arrow P3 into container 100 via water inlet 111 in order to be heated up or heated in container 100.

[0110] Furthermore, container 100 is configured to discharge or convey the heated or heated up water out of container 100 via water outlet 112. In this process, the heated up or heated water is conveyed in the flow direction according to arrow P4 out of container 100 via water outlet 112. In this case, the water at the water outlet has a final temperature which is increased compared to the initial temperature.

[0111] To convey the water into container 10 and out of container 100, a pump (not shown) can be used. Arrows P1 and P4 and arrows P2 and P3 run in opposite directions such that their conveying direction and/or flow direction runs in opposite directions.

[0112] When the water flows through container 100, the water is constantly heated up or heated by the waste heat and/or the heat of heat exchanger tube 2. In this way, it is possible to heat up and/or warm up the water of, for example, a water basin, in particular a swimming pool or a swimming pond.

[0113] In a further development of container 100, flow guide plates are disposed in the interior of container 100, said flow guide plates guiding the water flowing into the water inlet in such a manner that the water is forced to flow in close proximity to heat exchanger tube when flowing through the container in such a manner that it first flows along tube section 29, then along tube section 28, then along tube section 27, then along tube section 26, then along tube section 22, then along tube section 21 and finally leaves the container via water outlet 112 and subsequently can be further used. Thereby, the water can be heated up extremely efficiently.

[0114] In a further development of the container according to the invention, said container consists of a tube accommodating heat exchanger tube 20, the water to be heated up flowing through said tube and flowing around heat exchanger tube 20 in this process. In this process, the water to be heated up flows around the entire surface of the heat exchanger tube, the water also flowing through tubes 10 penetrating heat exchanger tube 20. A schematic illustration of such a device is illustrated in FIG. 12. In this case, the container or the tube accommodating heat exchanger tube 20 is designated by reference numeral 100. The water flowing in tube 100 is designated by reference numeral 115.
