Compared with the background technology, the turbulent flow component of the invention has the following beneficial effects: after installing in the heat exchange tube, because first vortex piece is located the intraductal peripheral region of heat exchange tube, the intraductal rivers of heat exchange tube can strengthen the disturbance of heat exchange tube intraductal internal face department rivers when first vortex piece like this, can break the boundary layer, can reduce the thickness of boundary layer simultaneously, play the effect of reinforcing heat transfer. Meanwhile, because the second vortex piece is located the intraductal middle part of heat exchange tube regional, on the one hand, the second vortex piece occupies the lower middle part region of rivers temperature, make the lower regional rivers in middle part of temperature less, on the other hand, when rivers in the heat exchange tube were through the second vortex piece, the second vortex piece can make the intraductal lower rivers flow to the intraductal region of heat exchange tube around and fully mix with regional higher rivers of temperature around to the intraductal rivers of heat exchange tube, produce the turbulent flow when the intraductal water current of heat exchange flows through the second vortex piece and show promptly, it is comparatively even to realize the intratubular rivers mix, promptly the intraductal rivers temperature of heat exchange tube is comparatively even, thereby just can reduce the intraductal bubble of heat exchange and meet cold and appear cracked bad phenomenon, can greatly reduced the intraductal bubble of.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Referring to fig. 1 and 2, fig. 1 is a schematic structural diagram of a heat exchange assembly according to an embodiment of the present invention, and fig. 2 is an enlarged structural diagram of fig. 1 at a. In an embodiment of the present invention, the spoiler assembly includes a first spoiler 10 and a second spoiler 20. The first spoiler 10 is connected to the second spoiler 20, and the first spoiler 10 is configured to be disposed at a peripheral region inside the heat exchange pipe 30. The first spoiler 10 is a spoiler spring. The second spoiler 20 is adapted to be disposed at a middle region inside the heat exchange tube 30 along an axial direction of the heat exchange tube 30.

After the turbulent flow component is arranged in the heat exchange tube 30, the first turbulent flow part 10 is arranged in the peripheral area in the heat exchange tube 30, so that the water flow in the heat exchange tube 30 can enhance the disturbance of the water flow on the inner wall of the heat exchange tube 30 when passing through the first turbulent flow part 10, the boundary layer can be broken, the thickness of the boundary layer can be reduced, and the effect of enhancing heat exchange is achieved. Meanwhile, because the second spoiler 20 is arranged in the middle area inside the heat exchange tube 30, on one hand, the second spoiler 20 occupies the middle area with lower water temperature, so that the water flow in the middle area with lower temperature is less, on the other hand, when the water flow inside the heat exchange tube 30 passes through the second spoiler 20, the second spoiler 20 can enable the water flow with lower temperature in the middle area inside the heat exchange tube 30 to flow to the surrounding area inside the heat exchange tube 30 and be fully mixed with the water flow with higher temperature in the surrounding area, that is, the water inside the heat exchange tube 30 generates turbulent flow when flowing through the second spoiler 20, so that the water flow inside the heat exchange tube 30 is more uniformly mixed, that is, the water flow inside the heat exchange tube 30 is more uniform in temperature, thereby reducing the bad phenomenon that the bubbles inside the heat exchange tube 30 are broken when being cooled, i.e., greatly reducing the noise generated by the broken bubbles. After the turbulent spring is arranged in the heat exchange tube 30, the turbulent spring has a good turbulent effect on the water flow at the inner wall area of the heat exchange tube 30.

Referring to fig. 2, further, the spoiler spring includes a first section spring 11, a middle section spring 12 and a tail section spring 13 connected in sequence. The first spoiler 20 is sleeved at the head end and the tail end of the first spoiler 11 and the tail spoiler 13 respectively and supported by the first spoiler 20. The outer diameters of the first section spring 11 and the tail section spring 13 are smaller than that of the middle section spring 12. The middle section spring 12 is sleeved outside the second spoiler 20 and used for abutting against the inner wall of the heat exchange tube 30 or providing a gap. So, because the middle part section spring 12 of second vortex piece 20 contradicts or is equipped with the clearance with the inner wall of heat exchange tube 30, the head end and the tail end of second vortex piece 20 correspond respectively and install on first section spring 11 and tail section spring 13, first section spring 11 and tail section spring 13 play the support positioning action to the head end and the tail end of second vortex piece 20 respectively to just can realize that second vortex piece 20 installs the middle part region in heat exchange tube 30 intraductal.

Referring to fig. 2 again, specifically, in order to achieve a better supporting and positioning effect of the first-stage spring 11 on the head end of the second spoiler 20, for example, a groove 21 is wound on an outer wall of the head end of the second spoiler 20, so that the first-stage spring 11 is positioned and sleeved in the groove 21. Similarly, in order to realize that the tail section spring 13 plays a better supporting and positioning role for the tail end of the second spoiler 20, for example, a groove 21 is wound on the outer wall of the tail end of the second spoiler 20, so that the tail section spring 13 is positioned and sleeved in the groove 21. Furthermore, in order to ensure the installation stability of the first section spring 11 on the groove 21 and ensure the turbulent flow effect of the middle section spring 12 on the peripheral area in the heat exchange tube 30, the pitch density of the first section spring 11 is greater than that of the middle section spring 12. Likewise, the pitch density of the tail section springs 13 is greater than the pitch density of the mid section springs 12.

Referring to fig. 2 to 4, fig. 3 is a schematic structural diagram of a heat exchange assembly according to another embodiment of the present invention, and fig. 4 is an enlarged structural diagram of fig. 3 at B. Alternatively, the groove 21 does not need to be wound on the outer wall of the head end of the second spoiler 20, and the groove 21 does not need to be wound on the outer wall of the tail end, but for example, the first section of the spring 11 is made into a cone shape (as shown in fig. 4), and the first section of the spring 11 is tightly sleeved and fixed on the head end of the second spoiler 20. Similarly, for example, the tail spring 13 is made into a cone shape, and the tail spring 13 is tightly sleeved and fixed on the tail end of the second spoiler 20.

Referring to fig. 5 and 6, fig. 5 is a schematic structural view illustrating a heat exchange assembly according to another embodiment of the present invention, and fig. 6 is an enlarged structural view of fig. 5 at C. In another embodiment, the spoiler spring includes a first section spring 11, a middle section spring 12, and a tail section spring 13 connected in sequence. The first section spring 11 and the tail section spring 13 are used for abutting against the inner wall of the heat exchange tube 30 or being provided with a gap. The outer diameters of the first section spring 11 and the tail section spring 13 are both larger than the outer diameter of the middle section spring 12, and the middle section spring 12 is sleeved outside the second spoiler 20 and used for supporting the second spoiler 20 in an abutting mode. So, because first section spring 11 contradicts or is equipped with the clearance with the inner wall of heat exchange tube 30 with last section spring 13, middle part section spring 12 cover is located outside second vortex piece 20 and is used for contradicting and support second vortex piece 20, so just can realize that second vortex piece 20 installs in the intraductal middle part region of heat exchange tube 30. In addition, since the middle section spring 12 is not in contact with the inner wall of the heat exchange tube 30, but is in contact with the inner wall of the heat exchange tube 30 through the first section spring 11 and the last section spring 13, the pressure at the water inlet of the heat exchange tube 30 can be reduced.

The lengths of the first-stage spring 11, the middle-stage spring 12, and the last-stage spring 13 are not limited herein, and may be set according to actual conditions. Specifically, the length of the middle spring 12 is greater than the lengths of the first spring 11 and the last spring 13. In addition, the proportional relationship between the length of the middle spring 12 and the length of the first spring 11 is, for example, 3: 1-10:1. Thus, it is possible to contribute to the reduction of the inlet pressure of the heat exchange pipe 30.

As a feasible scheme, the end of the second spoiler 20 is provided with an insertion hole, and the end of the spoiler spring is inserted into the insertion hole to be connected with the second spoiler 20, so that the second spoiler 20 is installed and fixed on the spoiler spring. Of course, the second spoiler 20 may be fixedly mounted on the spoiler spring by other methods, such as spot welding, bonding, clamping, fixing with mounting members such as screws and pins, etc., which are not limited herein.

Referring to fig. 2 and 10, fig. 10 is a schematic structural diagram of a heat exchanger according to an embodiment of the present invention. In one embodiment, the second spoiler 20 is mounted on a spoiler spring, and the second spoiler 20 is fixed by the spoiler spring. In addition, the two U-shaped tubes 40 connected to both ends of the heat exchange tube 30 are respectively abutted against and fixed to both ends of the spoiler spring, so that the spoiler spring can be fixedly installed in the heat exchange tube 30. It is understood that the spoiler spring may be fixedly installed in the heat exchange tube 30 by other methods, such as spot welding, bonding, clamping, fixing with a mounting member, such as a screw or a pin, etc., without limitation.

It is so seen that, set up second spoiler 20 at the intraductal middle part region of heat exchange tube 30 and along axial direction, second spoiler 20 is fixed in on the spoiler spring, installs in the intraductal middle part region of heat exchange tube 30 through the spoiler spring is fixed, can replace traditional spoiler, need not mould punching press or welded fastening, and the equipment is more convenient, can reduce cost.

Referring to fig. 5 and fig. 6, further, the second spoiler 20 has a spiral spoiler structure. The second spoiler 20 extends from one end of the heat exchange pipe 30 to the other end of the heat exchange pipe 30 along the axial direction of the heat exchange pipe 30. So, under the effect of spiral vortex structure, can make the lower rivers flow to the intraductal periphery region of heat exchange tube 30 of the intraductal middle part regional temperature of heat exchange tube 30 and fully mix with the higher rivers of peripheral region temperature, the rivers that produce the turbulent flow when the water in the heat exchange tube 30 flows through second vortex piece 20 show promptly, it is comparatively even to realize the rivers mix in the heat exchange tube 30, the rivers temperature in the heat exchange tube 30 is comparatively even promptly, thereby just can reduce the bubble in the heat exchange tube 30 and meet the cold and appear cracked bad phenomenon, can greatly reduced the noise that the bubble in the heat exchange tube 30 broke the production. Likewise, the first spoiler 10 extends from one end of the heat exchange pipe 30 to the other end of the heat exchange pipe 30 along the axial direction of the heat exchange pipe 30.

Referring to fig. 6 to 9, fig. 7 is a schematic structural view of a heat exchange assembly according to still another embodiment of the present invention, fig. 8 is an enlarged structural view of fig. 7 at D, and fig. 9 is a schematic structural view of fig. 7 with a heat exchange tube 30 removed. In one embodiment, the second spoiler 20 includes a main shaft 23. The main shaft 23 is wound with a spiral groove 24. When water flows through the second spoiler 20, the spiral groove 24 on the main shaft 23 can enable the water flow with lower temperature in the middle area inside the heat exchange tube 30 to flow to the surrounding area inside the heat exchange tube 30 and to be fully mixed with the water flow with higher temperature in the surrounding area, that is, the water inside the heat exchange tube 30 generates turbulent flow when flowing through the second spoiler 20, so that the water flow inside the heat exchange tube 30 is uniformly mixed. It should be noted that the spiral groove 24 may be formed on the outer wall of the main shaft 23 by, for example, milling, or integrally formed on the outer wall of the main shaft 23 by forging or casting, or the main shaft 23 with the spiral groove 24 may be formed on the main shaft 23 by twisting the main shaft 23 by using mechanical torque during the process of producing the main shaft 23 (as shown in fig. 8).

Optionally, referring to fig. 2 again, a spiral spoiler blade 25 is wound on the main shaft 23. When water flows through the second spoiler 20, the spoiler blades 25 on the main shaft 23 can enable the water flow with lower temperature in the middle area inside the heat exchange tube 30 to flow to the surrounding area inside the heat exchange tube 30 and to be fully mixed with the water flow with higher temperature in the surrounding area, that is, the water inside the heat exchange tube 30 generates turbulent flow when flowing through the second spoiler 20, so that the water flow inside the heat exchange tube 30 is uniformly mixed.

Referring to fig. 2, a cross section is formed on the spoiler blade 25 on a plane passing through the axial direction of the main shaft 23, the angle a of the cross section with respect to the axial center of the main shaft 23 is 27 ° to 33 °. Thus, when a is 27 ° to 33 °, the influence of the spoiler blade 25 on the flow velocity of the water stream is minimized. In addition, in areas with high water hardness, tests show that the scale formation prevention effect is best.

Referring to fig. 6 or 8, in one embodiment, the end of the second spoiler 20 has a cone shape, a semi-sphere shape, or a semi-ellipsoid shape. So, the tip of second spoiler 20 is less to the resistance of rivers, and rivers can flow forward along the terminal surface of second spoiler 20 fast when the terminal surface of second spoiler 20, can guarantee the velocity of flow to can reduce the vaporization noise. In addition, when the end of the second spoiler 20 is cone-shaped, the second spoiler 20 can also be easily inserted and fixed into the spoiler spring provided with the cone section. Alternatively, the end of the second spoiler 20 may have other shapes, such as a cylindrical shape, which provides greater resistance to water flow and greater vaporization noise than a cone-shaped end.

Referring to fig. 2 again, in one embodiment, a groove 21 is formed around an outer wall of an end portion of the second spoiler 20, the first spoiler 10 is a spoiler spring, and a spoiler spring sleeve is configured to be located outside the groove 21.

Specifically, the groove 21 may be formed on an outer wall of an end portion of the second spoiler 20 by milling, or may be obtained while the second spoiler 20 is integrally formed, or may be, for example, a bolt that divides the second spoiler 20 into a main shaft 23 and is installed on the main shaft 23, and a portion of the bolt is inserted into an end surface of the main shaft 23 and is matched with the end surface of the main shaft 23 to form the groove 21 disposed circumferentially around the second spoiler 20.

Referring again to FIG. 2, in one embodiment, the second flow perturbation element 20 is provided with a copper-based catalyst alloy element 26. Thus, the copper-based catalyst alloy member 26 can effectively prevent scaling; in addition, the second spoiler 20 limits and fixes the second spoiler 20 by being mounted on the second spoiler 20.

Optionally, the second spoiler 20 is specifically made of, for example, stainless steel or chrome-plated carbon steel, but may also be made of, for example, metal such as copper, aluminum, iron, and the like, which is not limited herein.

It should be noted that the copper-based catalyst alloy member 26 cannot be welded and can be machined, and the descaling principle is as follows: when water flows through the copper-based catalyst alloy part 26 at a certain speed, the copper-based catalyst alloy part 26 can release free electrons to the water flow and can enable the water flow to generate a polarization phenomenon, so that anions and cations in the water flow are not easy to combine to form scale, and hardened scale blocks can be gradually dissolved and fall off, thereby achieving the functions of scale prevention and scale removal. The capability of the copper-based catalyst alloy part 26 for releasing electrons is related to the contact area and the flow velocity of water flow, the larger the contact area is, the faster the flow velocity of water flow is, the more electrons the copper-based catalyst alloy part 26 releases, and the more obvious the anti-scaling and descaling effects are. In addition, the copper-based catalyst alloy member 26 is currently mainly used in boilers and is not used in pipes of gas water heating equipment.

Generally, the copper-based catalyst alloy member 26 has poor weldability and is substantially unweldable. Further, the copper-based catalyst alloy member 26 is, for example, designed as a bolt, and a screw hole 27 corresponding to the bolt is provided on the end surface of the second spoiler 20, and the copper-based catalyst alloy member 26 is mounted on the end surface of the second spoiler 20 by being inserted into the screw hole 27, and can be matched with the end surface of the second spoiler 20 to form the groove 21. The groove 21 can be used for fixing the spoiler spring.

Further, the cost of the copper-based catalyst alloy material is high, and if the entire second spoiler 20 is made of the copper-based catalyst alloy material, the cost is high, and the civil mass conversion cannot be effectively performed. In order to save the manufacturing cost and facilitate the assembly and fixation between the spoiler spring and the second spoiler 20, the copper-based catalyst alloy member 26 is, for example, processed into bolts, and the number of the copper-based catalyst alloy members 26 is two, and both end surfaces of the second spoiler 20 are provided with screw holes 27 matched with the copper-based catalyst alloy member 26, so that the two copper-based catalyst alloy members 26 are respectively installed in the two screw holes 27.

It can be understood that the end of the copper-based catalyst alloy part 26 may also be processed into a clamping structure, and a clamping hole adapted to the clamping structure is formed on the end surface of the second spoiler 20, and the clamping structure is mounted in the clamping hole to mount the copper-based catalyst alloy part 26 on the second spoiler 20, but the copper-based catalyst alloy part 26 may also be mounted and fixed on the second spoiler 20 by other methods, which are not limited herein.

Referring to fig. 2, 4, 6 or 8, in an embodiment, a heat exchange assembly includes a heat exchange tube 30 and a flow disturbing assembly according to any of the above embodiments, and the flow disturbing assembly is disposed in the heat exchange tube 30.

In the heat exchange assembly, the first flow disturbing piece 10 is arranged in the peripheral area in the heat exchange tube 30, so that the water flow in the heat exchange tube 30 can enhance the disturbance of the water flow on the inner wall of the heat exchange tube 30 when passing through the first flow disturbing piece 10, a boundary layer can be broken, the thickness of the boundary layer can be reduced, and the effect of enhancing heat exchange is achieved. Meanwhile, because the second spoiler 20 is arranged in the middle area inside the heat exchange tube 30, on one hand, the second spoiler 20 occupies the middle area with lower water temperature, so that the water flow in the middle area with lower temperature is less, on the other hand, when the water flow inside the heat exchange tube 30 passes through the second spoiler 20, the second spoiler 20 can enable the water flow with lower temperature in the middle area inside the heat exchange tube 30 to flow to the surrounding area inside the heat exchange tube 30 and be fully mixed with the water flow with higher temperature in the surrounding area, that is, the water inside the heat exchange tube 30 generates turbulent flow when flowing through the second spoiler 20, so that the water flow inside the heat exchange tube 30 is more uniformly mixed, that is, the water flow inside the heat exchange tube 30 is more uniform in temperature, thereby reducing the bad phenomenon that the bubbles inside the heat exchange tube 30 are broken when being cooled, i.e., greatly reducing the noise generated by the broken bubbles.

Specifically, the heat exchange tube 30 is an oxygen-free copper tube, the oxygen content of the oxygen-free copper tube is lower than 0.003%, the oxygen compound content is lower, and the oxygen-free copper tube can improve the heat exchange efficiency and has better corrosion resistance compared with a common copper tube. In addition, the inner wall of the heat exchange tube 30 is provided with threads, and the heat exchange tube 30 to be threaded is adopted, so that the turbulent flow effect can be improved. It should be understood that the specific material of the heat exchange tube 30 is not limited in this embodiment, for example, the heat exchange tube 30 may also be a common copper tube, a stainless steel tube, an iron tube, or the like.

Referring to fig. 2 and 10, in an embodiment, a heat exchange device includes a heat exchange assembly according to any one of the above embodiments. The heat exchange device may be a heat exchanger or a gas water heater, for example.

In the heat exchange device, the first flow disturbing piece 10 is arranged in the peripheral area in the heat exchange tube 30, so that the disturbance of water flow on the inner wall of the heat exchange tube 30 can be enhanced when the water flow in the heat exchange tube 30 passes through the first flow disturbing piece 10, a boundary layer can be broken, the thickness of the boundary layer can be reduced, and the effect of enhancing heat exchange is achieved. Meanwhile, because the second spoiler 20 is arranged in the middle area inside the heat exchange tube 30, on one hand, the second spoiler 20 occupies the middle area with lower water temperature, so that the water flow in the middle area with lower temperature is less, on the other hand, when the water flow inside the heat exchange tube 30 passes through the second spoiler 20, the second spoiler 20 can enable the water flow with lower temperature in the middle area inside the heat exchange tube 30 to flow to the surrounding area inside the heat exchange tube 30 and be fully mixed with the water flow with higher temperature in the surrounding area, that is, the water inside the heat exchange tube 30 generates turbulent flow when flowing through the second spoiler 20, so that the water flow inside the heat exchange tube 30 is more uniformly mixed, that is, the water flow inside the heat exchange tube 30 is more uniform in temperature, thereby reducing the bad phenomenon that the bubbles inside the heat exchange tube 30 are broken when being cooled, i.e., greatly reducing the noise generated by the broken bubbles.
