Background Art

[0002] Heat exchangers are known from the long-term state of the art. With known heat exchangers, heat energy can be transferred from one substance flow to another.

[0003] Known heat exchangers have the disadvantage that the degree of efficiency can be improved.

Summary of the Invention

[0004] The current object of the present invention is to overcome the disadvantages of the state of the art as described above.

[0005] According to the present invention, this object is achieved by a heat exchanger of the type mentioned at the beginning, the heat exchanger comprising a heat exchange tube and a plurality of tubes passing through the heat exchange tube and spaced apart from each other, the heat exchange tube having twice the number of openings based on the number of tubes, each tube being guided through two of these openings, and the tubes being connected to the heat exchange tube on both sides via their end tube sockets.

[0006] In this case, the heat exchange tube can be used to heat, warm and / or evaporate the fluid around the heat exchange tube, such as water, air, etc. Preferably, the fluid is a liquid.

[0007] The end tube socket is connected to the heat exchanger tube in the region of the opening of the heat exchanger tube. The end tube socket can be attached to or connected to the heat exchanger tube. The inner shell surface of the tube can form a common shell surface or surface with the remaining outer shell surface. Preferably, the opening thus serves to accommodate the tubes, especially their ends.

[0008] The fluid guided within the heat exchanger can be a liquid, water, etc. Preferably, the fluid within the heat exchanger tube is air.

[0009] In the heat exchanger according to the present invention, the use of tubes passing through the heat exchanger tubes enables the surface of the heat exchanger tubes to be expanded outwardly. Thereby, it is possible to achieve that the heated or high-temperature fluid (for example, air) within the heat exchanger tube reaches the tubes and the air experiences a swirling effect in this process.

[0010] Heat exchange is maximized through a large number of tubes. This is because here heat exchange is most effective and additional circulation occurs in the fluid surrounding the heat exchanger. The air within the heat exchanger tubes comes into contact with the shell surface of the heat exchanger tubes expanded by the plurality of tubes and transfers heat to the fluid (for example, liquid) surrounding the heat exchanger tubes of the heat exchanger.

[0011] Therefore, the degree of efficiency of the heat exchanger can be improved.

[0012] The shell surface of the heat exchanger becomes quite large when the amount of fluid to be heated used is small.

[0013] When a plurality of tubes are used, heat exchange is most effective. This is because here heat exchange is most effective and additional circulation occurs in the fluid surrounding the heat exchanger. This has been confirmed by tests.

[0014] The plurality of tubes can also be understood as a plurality of tubes. Further, the heat exchanger tubes can also be understood as tube ducts.

[0015] The tubes passing through the heat exchanger tubes are tubes arranged within the heat exchanger and / or tubes guided through the heat exchanger. The tubes can be made hollow, particularly in the form of a hollow cylinder. In particular, the tubes are realized as round tubes or square tubes. Further designs are also conceivable.

[0016] A fluid, particularly in the form of air, can be heated, for example, by a burner arranged in the heat exchanger on the inlet side, and the heat exchanger is configured to heat the fluid surrounding the heat exchanger, for example, in a container. Further, a fan can be arranged on the heat exchanger on the outlet side so that it is not necessary for the burner to push air through the heat exchanger and air can be sucked in.

[0017] The connection of the end tube socket to the heat exchanger tube is realized or formed in a fluid-tight manner. By the fluid-tight realization, it is possible to prevent the mixing of, for example, air in the heat exchanger tube and the fluid to be heated, to be warmed, or to be evaporated.

[0018] The heat exchanger can be an evaporator, and the heat exchanger tubes can be evaporation tubes.

[0019] Preferably, the openings are arranged radially, and / or the central longitudinal axis of the tube extends perpendicular to the central longitudinal axis of the heat exchanger tube. This arrangement can further enhance the swirling effect of the hot air in the heat exchanger.

[0020] The radial arrangement can be understood as an arrangement in which the central longitudinal axis of the tube intersects perpendicularly with the central longitudinal axis of the heat exchanger tube. In other words, the central longitudinal axis of each tube extends through the center of the heat exchanger tube. Thereby, a symmetrical orientation of the tubes with respect to the heat exchanger tubes can be achieved.

[0021] More preferably, the tubes are arranged spirally within the heat exchanger tubes. Due to this arrangement, the swirling effect of the high-temperature air in the heat exchanger can be further enhanced.

[0022] The spiral arrangement can also be understood as an arrangement such as spiral, helical, spiral shape, etc.

[0023] The tubes can be offset from each other and extend spirally within the heat exchanger tubes.

[0024] When the individual tubes are arranged spirally relative to each other within the heat exchanger tubes, preferably, the openings within the heat exchanger tubes are arranged on opposite sides of each other.

[0025] Alternatively, the tubes can be guided obliquely within the heat exchanger tubes. That is, the central longitudinal axis of the tubes forms an angle with the central longitudinal axis of the heat exchanger tubes.

[0026] Preferably, in the axial direction of the heat exchanger tubes or along the axial direction, the tubes are offset from each other at an angle α within the range of 15° to 25°, particularly 20°. In this arrangement, an enhanced swirling effect of the air within the heat exchanger occurs in the tubes.

[0027] In another preferred embodiment of the heat exchanger according to the present invention, the diameter of the tubes is within the range of 1 / 6 to 1 / 2 of the diameter of the heat exchanger tubes, particularly 1 / 4. In this arrangement, an enhanced swirling effect of the air within the heat exchanger occurs in the tubes. Particularly preferably, the end tube sockets project onto the heat exchanger tubes at their ends. Thereby, the tubes can be easily attached to or fixed to the heat exchanger tubes.

[0029] Particularly preferably, the heat exchanger tube comprises three tube sections (regions), the second tube section connecting the first tube section and the third tube section to each other, and the first tube section and the third tube section being arranged parallel to each other.

[0030] The first tube section can be understood as the tube section on the combustion tube side or the combustion tube. The second tube section can be understood as the connecting tube. The third tube section can be understood as the tube section on the fan side or the fan tube.

[0031] Alternatively, the heat exchanger tube can also be integrally formed. In this case, the first end section of the heat exchanger tube can be arranged parallel to the second end section of the heat exchanger tube. In this case, the heat exchanger tube has corresponding curvatures or bends.

[0032] Preferably, the heat exchanger comprises an attachment plate for connection to a heat exchanger device and / or an evaporation device. By providing the attachment plate, the heat exchanger can be inserted into the evaporation device and into the heat exchanger device. In this case, it is required that both the evaporation device and the heat exchanger device have corresponding designs for accommodating the attachment plate.

[0033] Particularly preferably, the attachment plate has two openings for accommodating the first tube section and the third tube section.

[0034] In this case, the heat exchanger tube can be realized such that the first tube section of the heat exchanger tube is guided through the first opening of the attachment plate, and the third tube section of the heat exchanger tube is guided through the second opening of the attachment plate. Thereby, the first tube section of the heat exchanger tube and the third tube section of the heat exchanger tube can be guided through one and the same component.

[0035] Preferably, the heat exchanger tube has a 180° bend or is bent multiple times.

[0036] More preferably, the second tube section comprises additional tubes, which penetrate at least the shell-side combustion tube-side tube section and the fan-side tube section and extend and / or are arranged within the second tube section.

[0037] When the heat exchanger according to the invention is used for heating a liquid medium, in particular water, it is advantageous if the heat exchanger tube is a tube having a larger diameter, through which the liquid medium to be heated flows and around which the heat exchanger tube flows in this process.

[0038] Particularly preferably, the heat exchanger comprises a flange having two openings for connection to a gas burner and a fan, and the flange is arranged at the end of the tube section of the heat exchanger tube.

DETAILED DESCRIPTION OF THE INVENTION

[0073] FIG. 1 shows a heat exchanger 1 according to the present invention, which has heat exchanger tubes 2. The heat exchanger tubes 2 serve to warm, heat and / or evaporate a fluid, such as a liquid, surrounding the heat exchanger tubes 2.

[0074] The heat exchanger tubes 2 include three tube sections 20, 21, 22. The second tube section 21 connects the first tube section 20 and the third tube section 22 to each other. In this case, the first tube section 20 and the third tube section 22 are arranged parallel to each other.

[0075] Furthermore, a plurality of tubes 10 are shown. The tubes 10 penetrate the heat exchanger tubes 2, particularly the first tube section 20 and the third tube section 22, and the tubes 10 are spaced apart from each other. The tubes 10 are arranged spirally in the heat exchanger tubes 2. The heat exchanger tubes 2 have openings in a number twice the number of the tubes 10, and the openings are arranged in the diameter direction. Each tube 10 is guided or extends through two of these openings. The tubes 10 are connected to the heat exchanger tubes 2 on both sides via their end tube sockets 11 and 12 in the region of the openings. This connection is fluid-tight. Each individual tube 10 is realized as a hollow cylindrical tube.

[0076] By providing the tubes 10 penetrating the heat exchanger tubes 2, the shell surface of the heat exchanger is considerably enlarged.

[0077] Furthermore, the heat exchanger 1 has an attachment plate 14. The attachment plate 14 has two openings 15 and 16 for accommodating the first tube section 20 and the third tube section 22 of the heat exchanger tube 2. In this case, the heat exchanger 2 is realized such that the first tube section 20 of the heat exchanger tube 2 is guided through the first opening 15 of the attachment plate 14 and the third tube section 22 of the heat exchanger tube 2 is guided through the second opening 16 of the attachment plate 14. The attachment plate 14 is configured to insert and mount the heat exchanger 1 into the heat exchanger device and / or the evaporation device.

[0078] The first tube section 20 disposed at the top of the sheet plane can be understood as the tube section on the combustion tube side. The third tube section 22 disposed at the bottom of the sheet plane can be understood as the 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 the second tube section 21.

[0079] The second tube section 21 includes an additional tube 10'. The additional tube 10' penetrates at least the tube section 20 on the combustion tube side and the tube section 22 on the fan side on the shell side and extends within the second tube section 21. Similar to the tube 10, the tube 10' is connected to the heat exchanger tube 2 on both sides via its end tube sockets.

[0080] Furthermore, the heat exchanger 1 has a flange 17 provided with two openings. The flange 17 is disposed at the ends of the two tube sections 20, 22. The flange 17 is configured to connect the gas burner and the fan in the heat exchanger 1. For this purpose, a gas burner attachment 18 and a fan attachment 19 are disposed on the flange 17.

[0081] The conveying direction of the air heated by a gas burner (not shown) is indicated by an arrow P1. The conveying direction of the cooled air sucked by a fan (not shown) is indicated by an arrow P2.

[0082] In the heat exchanger 1 according to the present invention, by using the tubes 10 penetrating through the heat exchanger tubes 2, it becomes possible to expand or enlarge the surface of the heat exchanger tubes 2 outward. As a result, it is possible to achieve that the heated or high-temperature air in the heat exchanger tubes 2 reaches the tubes 10 and that the air experiences a swirling effect in this process.

[0083] Heat exchange is maximized in a large number of tubes 10. This is because the heat exchange here is the most effective and an additional circulation occurs in the liquid surrounding the heat exchanger 1. The air in the heat exchanger contacts the shell surface of the heat exchanger tubes 2 expanded by the plurality of tubes 10 and transfers heat to the liquid surrounding the heat exchanger tubes 2 of the heat exchanger 1.

[0084] FIG. 2 is a side view of the heat exchanger 1, and also shows the regions of the individual tubes 10 and 20 that are not actually visible. Optionally, the first and third tube sections 20 and 22 can further include connection tube sections 3 and 4 that allow the first and third tube sections 20 and 22 to be attached to the flange 17.

[0085] FIG. 3 shows the detail A of FIG. 2. As shown above, the heat exchanger tubes 2 have openings 5 and 6 arranged in the diameter direction and have twice the number of openings 5 and 6 based on the number of tubes 10, and each tube 10 is guided through two of these openings 5 and 6. In this case, the central longitudinal axis 13 of the tube 10 extends while being orthogonal to the central longitudinal axis 9 of the heat exchanger tube 2. The diameter of the tube 10 corresponds to about 1 / 5 of the diameter of the heat exchanger tube 2. As a result, in the tube 10, the swirling effect of the air in the heat exchanger tube 2 is enhanced.

[0086] Furthermore, the end tube sockets 11, 12 of each tube 10 slightly protrude on both sides of the heat exchanger tube 2. This enables easy realization of a welded connection, a rolled connection, or a press connection between the end tube sockets 11, 12 and the heat exchanger tube 2.

[0087] FIG. 4 is a view showing the A-A cross section of FIG. 1. In the axial direction of the heat exchanger tube 2, the tubes 10 are offset relative to each other at an angle α of about 20°. This makes it possible to strengthen the swirling effect of the air in the heat exchanger tube 2 with the tubes 10.

[0088] The central longitudinal axis 13 of the tube 10 intersects the central longitudinal axis 9 of the heat exchanger tube 2 at a right angle.

[0089] FIG. 5 is a bottom view of the heat exchanger 1 according to the invention of FIG. 1, and the regions of the individual tubes 10 that are not actually visible are also shown here.

[0090] FIG. 6 is a perspective view showing the evaporator 30 according to the present invention. The evaporator 30 has a housing 31 and a condenser 34. The housing 31 is provided with at least one opening 32. The opening 32 serves to insert the heat exchanger 1 into the evaporator 30 and fix the attachment plate 14 of the heat exchanger 1 according to FIGS. 1 to 5 to the housing 31. Inside the housing 31, there is a fluid to be evaporated, in particular, a liquid.

[0091] Therefore, the heat exchanger 1 can be accommodated in the housing 31 together with the integrated attachment plate 14.

[0092] The evaporation device 30 is configured to convey steam through at least one constricted duct 33 to the condenser 34. The condenser 34 includes a deflector plate that deflects the steam laterally and condenses the steam as a result of the cooling process. The condensed water generated in this process can be collected by respective channels 35 on both sides of the housing 31 and can be led to a tube system 36. In this case, the tube system 36 can be designed as a kind of siphon. The design as a siphon generates a backpressure in the evaporation device 30 that enhances the evaporation effect.

[0093] FIG. 7 shows a perspective view of a heat exchanger device 40 according to the present invention. The heat exchanger device 40 has a housing 41. The housing 41 includes at least one opening 42. The opening 42 serves to insert the heat exchanger 1 into the heat exchanger device 40 and fix the attachment plate 14 of the heat exchanger 1 according to FIGS. 1 to 5 to the housing 41. Inside the housing 41 is a fluid, particularly a liquid, to be heated and / or evaporated.

[0094] The heat exchanger device 40 is designed as a sealed container capable of mounting the heat exchanger 1. When the heat exchanger 1 is mounted, waste heat can be led again from the evaporation device 30 through the heat exchanger device 40, for example, to preheat a liquid that is to be subsequently led to the evaporation device 30.

[0095] FIG. 8 shows a perspective view of a facility 50 according to the present invention. As shown, the facility 50 includes a frame or stand or platform 51 for accommodating the evaporation device 30 according to FIG. 6 and the heat exchanger device 40 according to FIG. 7. The evaporation device 30 includes a gas burner 24 and a fan 25. The heat exchanger device 40 has two attachment sockets 43 and 44.

[0096] The equipment 50 is designed such that the evaporation device 30 and the heat exchanger device 40 are arranged on the frame / stand 51. The devices 30 and 40 can be stacked in any type of manner. In order to transfer the liquid from the heat exchanger device 40 to the evaporation device 30, the two devices 30 and 40 can be connected by a plurality of conduits.

[0097] Both the evaporation device 30 and the heat exchanger device 40 can be mounted on the frame / stand 51 at an inclination of about 1.5° so that the condensed water generated in the heat exchanger device 40 can flow out.

[0098] The gas burner 24, the fan 25 and the attachment sockets 43, 44 are designed such that each has the same attachment, and thus they can be mounted on the equipment 50 at the flange 17 of the heat exchanger 1 as required.

[0099] In the previous case, the burner 24 and the fan 25 were mounted on the evaporation device 30. Further, the fan 25 was connected via the attachment socket 43. As a result, the exhaust heat is guided and / or pushed through the heat exchanger device 40.

[0100] However, in the previous case, it would also be possible to replace the fan 25 with the attachment socket 43 and connect the two attachment sockets 43, 44. In this case, the exhaust will also be drawn through the heat exchanger device 40.

[0101] Advantageously, a plurality of heat exchanger devices 40 can be coupled to each other, for example, to achieve an improved heat output.

[0102] FIG. 9 shows a container 100, particularly a water container. The container 100 comprises a housing 101 having a cover 102. The housing 101 is cylindrical and has a bottom. Further, the container 100 comprises heat exchanger tubes 2.

[0103] The heat exchanger tube 2 has a plurality of tube sections 20, 21, 22, 26, 27, 28, 29. The tube sections 20, 21, 22, 26, 27, 28, 29 of the heat exchanger tube 2 are numbered continuously in the conveying direction and / or the flow direction (arrows P1, P2).

[0104] Among the tube sections 20, 21, 22, 26, 27, 28 and 29, four tube sections 20, 22, 27 and 29 are arranged parallel or coaxial to each other within the container with respect to the central longitudinal axis of the container 100. Two tube sections 20 and 22 are connected to the tube section 21 realized as a 180° bend. Two tube sections 22 and 27 are connected to the tube section 26 realized as a 180° bend. Two tube sections 27 and 29 are connected to the tube section 28 realized as a 180° bend.

[0105] For clarity, in FIG. 9, the water inlet and the water outlet are not shown. In FIG. 10 based on FIG. 9, the water inlet 111 and the water outlet 112 are shown.

[0106] The container 100 includes a cover 102 as shown in FIG. 11 in addition to the cylindrical housing 101. In order to connect the cover 102 to the housing 101 of the container 100, a seal 103, a screw connection part 104, etc. are provided. The cover 102 is provided with one attachment for the gas burner 24 and one attachment for the fan 25 respectively. Further, the cover 102 has a water inlet 111 and a water outlet 112. A flexible tube 105 can be arranged at the water inlet 111. A flexible tube 106 can be arranged at the water outlet 112.

[0107] The shape of the heat exchanger tube 2 shown in FIG. 11 is actually not visible, but is shown in the figure for better understanding.

[0108] The container 100 is configured to heat or warm the water introduced or conveyed into the container 100 through the water inlet 111 by means of the heat exchanger tube 2. In this process, the water having an initial temperature at the water inlet 111 is conveyed into the container 100 through the water inlet 111 in the flow direction indicated by the arrow P3 in order to be heated or warmed within the container 100.

[0109] Furthermore, the container 100 is configured to discharge or convey the heated or warmed water out of the container 100 through the water outlet 112. In this process, the heated or warmed water is conveyed out of the container 100 through the water outlet 112 in the flow direction indicated by the arrow P4. In this case, the water at the water outlet has a final temperature that has risen compared to the initial temperature.

[0110] A pump (not shown) can be used for introducing water into the container 10 and discharging water from the container 100. The arrows P1, P4 and the arrows P2, P3 extend such that their conveying direction and / or flow direction are opposite.

[0111] When water flows through the container 100, the water is always heated or warmed by the waste heat and / or the heat of the heat exchanger tube 2. In this way, for example, the water in a water basin, particularly in a swimming pool or a swimming pond, can be heated and / or warmed.

[0112] As a further development of the container 100, a flow guide plate is arranged inside the container 100, and the flow guide plate guides the water flowing into the water inlet such that when the water flows through the container, it first flows along the tube section 29, then along the tube section 28, then along the tube section 27, then along the tube section 26, then along the tube section 22, then along the tube section 21, and finally flows out of the container through the water outlet 112 and can then be used further, flowing close to the heat exchanger tube 20. Thereby, the water can be heated extremely efficiently.

[0113] As a further development form of the container according to the present invention, the container consists of a tube that houses the heat exchanger tube 20. In this process, the water to be heated flows through the tube, flowing around the heat exchanger tube 20. In this process, the water to be heated flows around the entire surface of the heat exchanger tube, and the water also flows through the tube 10 that penetrates the heat exchanger tube 20. A schematic diagram of such a device is shown in FIG. 12. In this case, the container or tube that houses the heat exchanger tube 20 is designated by the reference numeral 100'. The water flowing inside the tube 100' is designated by the reference numeral 115. [Configuration 1] A heat exchanger (1), in particular a heat exchanger for heating, heating and / or evaporating a fluid, wherein the heat exchanger (1) comprises a heat exchanger tube (2) and a plurality of tubes (10) passing through the heat exchanger tube (2) and spaced apart from each other, the heat exchanger tube (2) having a number of openings (5, 6) that is twice the number of the tubes (10), each tube (10) being guided through two of these openings (5, 6), and the tubes (10) being connected to the heat exchanger tube (2) on both sides via their end tube sockets (11, 12).
