Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0026] Please refer to the following: Figures 1 to 3 This utility model provides a heat exchange tube 100, including a tube body 20 and a turbulence mechanism 40 installed within the tube body 20. The turbulence mechanism 40 includes at least two helical turbulence vanes 41. The length direction of each helical turbulence vane 41 is the same as the axial direction of the tube body 20, and each helical turbulence vane 41 has a first end and a second end opposite to each other along the axial direction of the tube body 20. Figure 1 and Figure 2 As shown, in the at least two spiral turbulence vanes 41 included in the turbulence mechanism 40, at least one spiral turbulence vane 41 and another spiral turbulence vane 41 are coaxially arranged along the axial direction of the tube body 20 (that is, at least two spiral turbulence vanes 41 are arranged in the same column along the axial direction of the tube body 20), and the first end of the at least one spiral turbulence vane 41 and the second end of the coaxial other spiral turbulence vane 41 are staggered along the circumference of the tube body 20. In other words, the adjacent ends of the two spiral turbulence vanes 41 arranged in the same column are staggered.
[0027] It is understood that in the heat exchange tube 100 provided in the embodiment of this utility model, by installing a turbulence mechanism 40 including at least two spiral turbulence vanes 41 inside the tube body 20, each spiral turbulence vane 41 can play a spiral guiding role for the fluid flowing into the tube body 20, thereby making the fluid inside the tube body 20 turbulent. By setting at least two spiral turbulence vanes 41 to be coaxially arranged and their adjacent ends to be cross-staggered, they can play a cutting and reversing role for the fluid inside the tube body 20, thereby disturbing the flow state of the fluid and enhancing the mixing of the fluid. In this way, it helps to prolong the heat exchange time of the fluid inside the tube body 20 and improve the heat exchange efficiency of the heat exchange tube 100.
[0028] In embodiments of this utility model, the tube 20 can be a straight-extending tube or a curved-extending tube, and the at least two spiral turbulence vanes 41 included in the turbulence mechanism 40 can be arranged in at least one row along the axial direction of the tube 20, and the number of spiral turbulence vanes 41 in the same row is at least one. Specifically, in Figures 1 to 3 In the example, the tube 20 is a straight-line extending tube, which helps to reduce the manufacturing difficulty of the tube 20; at least two helical turbulence vanes 41 are arranged in a row along the axial direction of the tube 20, which facilitates installation inside the tube 20. The tube 20 and the helical turbulence vanes 41 are not limited to being made of stainless steel, aluminum alloy or other materials, and there is no limitation on this.
[0029] Optionally, such as Figure 2 As shown, in one embodiment of this utility model, the ratio of the pitch L of the spiral turbulence vane 41 to the diameter D of the spiral turbulence vane 41 is 2 to 4. For example, the ratio of the pitch L of the spiral turbulence vane 41 to the diameter D of the spiral turbulence vane 41 can preferably be 3.5. In this embodiment, by limiting the ratio of the pitch L of the spiral turbulence vane 41 to the diameter D to a reasonable range, it is possible not only to avoid the spiral turbulence vane 41 having too small a pitch, thus weakening its turbulent effect on the fluid, but also to avoid the spiral turbulence vane 41 having too large a pitch, thus increasing the manufacturing difficulty of the spiral turbulence vane 41, thereby ensuring that the spiral turbulence vane 41 has a good turbulence effect.
[0030] The diameter of the spiral turbulence vane 41 can be equal to or slightly smaller than the inner diameter of the tube 20. In this way, the at least two spiral turbulence vanes 41 included in the turbulence mechanism 40 can be arranged in a row inside the tube 20, which can reduce the installation difficulty of the turbulence mechanism 40. Of course, the diameter of the spiral turbulence vane 41 can also be much smaller than the inner diameter of the tube 20. In this way, the at least two spiral turbulence vanes 41 included in the turbulence mechanism 40 can be arranged in at least two rows inside the tube 20, and the orthogonal projections of the spiral turbulence vanes 41 in different rows on the plane perpendicular to the axial direction of the tube 20 do not overlap. In this way, the turbulence mechanism 40 can play a turbulent role on the fluid in different areas inside the tube 20, thereby improving the turbulence effect of the turbulence mechanism 40, further enhancing the mixing of the fluid inside the tube 20, and thus improving the heat exchange efficiency of the heat exchange tube 100.
[0031] Optionally, such as Figure 1 and Figure 2As shown, in one embodiment of this utility model, the turbulence mechanism 40 includes at least two spiral turbulence vanes 41 arranged in at least one column along the axial direction of the tube body 20. In each column of spiral turbulence vanes 41, the first end of each spiral turbulence vane 41 and the second end of the adjacent spiral turbulence vane 41 are staggered along the circumference of the tube body 20. That is, in this embodiment, in all the spiral turbulence vanes 41 in the same column, the adjacent ends of each pair of adjacent spiral turbulence vanes 41 are staggered. In this way, the fluid in the tube body 20 can be cut and reversed to the maximum extent, thereby maximizing the mixing of the fluid and helping to further extend the heat exchange time of the fluid in the tube body 20 and improve the heat exchange efficiency of the heat exchange tube 100.
[0032] Preferably, in Figure 1 and Figure 2 In the illustrated embodiment, in each column of spiral turbulence vanes 41, the first end of each spiral turbulence vane 41 is staggered at 90 degrees to the second end of an adjacent spiral turbulence vane 41 along the circumference of the tube 20. In this embodiment, by limiting the adjacent ends of two adjacent spiral turbulence vanes 41 to be staggered at 90 degrees, the fluid within the tube 20 can be maximized to reverse its flow, thereby maximizing the heat exchange time and further improving the heat exchange efficiency of the heat exchange tube 100. Of course, in other embodiments of this invention, the first end of each spiral turbulence vane 41 and the second end of an adjacent spiral turbulence vane 41 can be staggered at 30 degrees, 45 degrees, 60 degrees, or other reasonable angles along the circumference of the tube 20; this is not limited.
[0033] Preferably, in one embodiment of this invention, the helical angle between the first and second ends of the spiral turbulence vane 41 is α, where α = N * 180°, and N is an integer greater than or equal to 1. In this embodiment, the opposite ends of the spiral turbulence vane 41 are spiraled circumferentially along the tube body 20 by an integer multiple of 180 degrees, which ensures that the opposite ends of the spiral turbulence vane 41 are located on the same plane, facilitating the positioning and installation of both ends of each spiral turbulence vane 41, and reducing the manufacturing difficulty of the spiral turbulence vane 41. Of course, in other embodiments of this invention, the helical angle α between the first and second ends of the spiral turbulence vane 41 can also be other reasonable angles, such as, but not limited to, 120 degrees, and is not limited thereto.
[0034] For further details, please refer to Figure 1 and Figure 2In one embodiment of this utility model, the turbulence mechanism 40 further includes at least one connecting piece 43, each connecting piece 43 extending axially along the tube body 20 and located between two coaxially arranged spiral turbulence plates 41. In this embodiment, by providing a connecting piece 43 extending axially along the tube body 20 between two coaxially arranged spiral turbulence plates 41, instead of providing spiral turbulence plates 41 throughout the entire tube body 20, the resistance to fluid flow within the tube body 20 can be appropriately reduced, avoiding excessively slow fluid flow and thus reducing the heat exchange efficiency of the heat exchange tube 100.
[0035] Optionally, among all the spiral turbulence vanes 41 arranged in the same column along the axial direction of the tube body 20, a connecting piece 43 may be provided between every two adjacent spiral turbulence vanes 41, or a connecting piece 43 may be provided between every two or more spiral turbulence vanes 41. Specifically, in Figure 1 and Figure 2 In the embodiment shown, among all the spiral turbulence vanes 41 arranged in the same column along the axial direction of the tube body 20, a connecting piece 43 is provided between every two spiral turbulence vanes 41. The connecting piece 43 can be connected to the adjacent spiral turbulence vanes 41, and between two adjacent spiral turbulence vanes 41, by any means such as welding or bonding, so that the turbulence mechanism 40 is connected as a whole.
[0036] Preferably, in Figure 1 and Figure 2 In the illustrated embodiment, at least one end of the connecting piece 43 is staggered with the end of the adjacent spiral turbulence plate 41 along the circumference of the tube body 20. That is, in this embodiment, the ends of the connecting piece 43 and the spiral turbulence plate 41 that are adjacent to each other are also staggered, which can also cut and reverse the fluid in the tube body 20, thereby prolonging the heat exchange time of the fluid and improving the heat exchange efficiency of the heat exchange tube 100.
[0037] For further details, please refer to Figure 1 and Figure 3 In one embodiment of this utility model, the heat exchange tube 100 further includes a plurality of fins 60 disposed on the outer peripheral wall of the tube body 20. In this embodiment, by providing a plurality of fins 60 on the outer peripheral wall of the tube body 20, it is beneficial to increase the heat exchange area of the tube body 20, thereby improving the heat exchange efficiency of the heat exchange tube 100. The fins 60 may be, but are not limited to, a plate-like structure or a columnar structure, and are not limited thereto.
[0038] Preferably, in Figure 1 and Figure 3In the illustrated embodiment, multiple fins 60 constitute at least two fin ring groups, which are spaced apart along the axial direction of the tube body 20. Each fin ring group includes at least two fins 60 spaced apart along the circumferential direction of the tube body 20. The at least two fins 60 in each fin ring group are staggered with the at least two fins 60 in an adjacent fin ring group along the circumferential direction of the tube body 20. It is easy to understand that by staggering the multiple fins in the at least two fin ring groups on the outer peripheral wall of the tube body 20, the heat exchange efficiency of the heat exchange tube 100 can be further improved.
[0039] In this case, the at least two fins 60 in each fin ring group and the at least two fins 60 in another adjacent fin ring group can be staggered at any reasonable angle such as 30 degrees, 45 degrees or 60 degrees along the circumference of the tube body 20, without any limitation.
[0040] It should be noted that, in the embodiments of this utility model, both ends of the turbulence mechanism 40 can extend out of the tube body 20 and be fixed by fasteners such as fixing brackets or bolts, for example in... Figure 1 In the embodiment shown, the turbulence mechanism 40 has a spiral turbulence vane 41 at each end. Each spiral turbulence vane 41 has a notch at one end extending out of the tube body 20. The notch can hold a bolt and be fixedly connected to a reference component (e.g., the sealing plate of the cooler using the heat exchange tube 100) by the bolt, so that the turbulence mechanism 40 is relatively fixedly installed inside the tube body 20 and the heat exchange tube 100 is fixed by the bolt.
[0041] Of course, in other embodiments of this utility model, the turbulence mechanism 40 can be fixedly installed in the tube body 20 using other connection methods. For example, the turbulence mechanism 40 can be provided with a locking block, and the inner walls at both ends of the tube body 20 can be provided with locking grooves. The turbulence mechanism 40 can be fixedly installed in the tube body 20 by the cooperation of the locking block and the locking groove. Similarly, the heat exchange tube 100 can also be fixed in other ways according to actual needs, such as not limited to locking.
[0042] Please combine Figure 4 and Figure 5The present invention also provides a cooler 1000, including a cooler housing 200 and at least one heat exchange tube 100 as described in any of the above embodiments. The tube body 20 of the heat exchange tube 100 is disposed in the inner cavity of the cooler housing 200. The two openings of the tube body 20 are respectively located on opposite sides of the cooler housing 200. Each opening of the tube body 20 is exposed to the corresponding side of the cooler housing 200, and the portion of the tube body 20 adjacent to the opening is sealed to the corresponding side of the cooler housing 200. The outer peripheral wall of the cooler housing 200 is provided with a first fluid inlet / outlet 210 and a second fluid inlet / outlet 220, which are respectively connected to the inner cavity of the cooler housing 200.
[0043] It is understood that in the cooler 1000 provided in the embodiments of this utility model, the first fluid inlet / outlet 210 and the second fluid inlet / outlet 220 can be used as the inlet / outlet of the first fluid (such as cooling water), and the pipe openings at the opposite ends of the tube body 20 of the heat exchange tube 100 can be used as the inlet / outlet of the second fluid (such as the fluid of materials), thereby realizing heat exchange between the first fluid and the second fluid, so as to achieve the purpose of cooling the fluid with higher temperature in the first fluid and the second fluid. The heat exchange tube 100 incorporates a turbulence mechanism 40 within the tube body 20, comprising at least two spiral turbulence vanes 41. Each spiral turbulence vane 41 guides the fluid flowing into the tube body 20 in a spiral manner, resulting in a turbulent flow. The fact that at least two spiral turbulence vanes 41 are coaxially arranged with their adjacent ends staggered allows them to cut and reverse the flow of fluid within the tube body 20, thereby disrupting the fluid's flow state and enhancing its mixing. This helps to extend the heat exchange time of the fluid within the tube body 20, improves the heat exchange efficiency of the heat exchange tube 100, and consequently enhances the cooling effect of the cooler 1000 using the heat exchange tube 100.
[0044] The sealing connection between the portion of the pipe body 20 near the pipe opening and the corresponding side of the cooler housing 200 can be achieved using existing cooler sealing technologies, such as, but not limited to, the combination of a sealing plate and a sealing ring, which will not be elaborated further.
[0045] like Figure 4 and Figure 5As shown, similar to existing coolers, the cooler 1000 provided in the embodiments of this utility model also includes other components or other structures, such as, but not limited to, an exhaust port 230 provided on the cooler housing 200, two end caps 300 detachably installed at opposite ends of the cooler housing 200, and four casters 400 installed at the bottom of the cooler housing 200, etc., wherein each end cap 300 has a material inlet / outlet 310 and a drain port 320; of course, the cooler 1000 may also have other similar structures of existing coolers, which will not be described in detail.
[0046] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or a connection within two components.
