Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat exchanger technology, and in particular to a turbulence deflector and a heat exchanger. Background Technology
[0002] In the heat exchanger of a gas water heater, stainless steel is used instead of copper for the heat exchange tubes to reduce costs and improve corrosion resistance. However, because stainless steel heat exchange tubes have a lower thermal conductivity, the inner wall temperature at the lower part (near the flue gas side) is relatively high while the water temperature at the upper part is relatively low. This leads to scale buildup at the lower part of the heat exchange tube over time, reducing its thermal conductivity. Furthermore, excessively high inner wall temperatures can cause vaporization noise, accelerating scale formation and further reducing the heat exchange tube's thermal conductivity. Utility Model Content
[0003] One of the technical problems solved by this utility model is to provide a baffle plate that can effectively solve the technical problems in the prior art where scale and vaporization noise easily occur inside the heat exchange tube, leading to a decrease in heat exchange performance.
[0004] The second technical problem solved by this utility model is to provide a heat exchanger that can effectively solve the technical problems in the prior art where scale and vaporization noise easily occur inside the heat exchange tubes, leading to a decrease in heat exchange performance.
[0005] The first technical problem mentioned above is solved by the following technical solution:
[0006] A deflector, wherein the deflector is provided with a first deflector flow hole and a second deflector flow hole that are alternately arranged along the length direction and both penetrate through the thickness direction of the deflector; the first deflector flow hole has a first sidewall and a second sidewall that are arranged opposite to each other along the length direction, and the second deflector flow hole has a third sidewall and a fourth sidewall that are arranged opposite to each other along the length direction;
[0007] The first sidewall is turned outward to form a first turbulence wall, the second sidewall is turned outward to form a second turbulence wall, the third sidewall is turned outward to form a third and a fourth turbulence wall, and the fourth sidewall is turned outward to form a fifth and a sixth turbulence wall; the first, third, and fourth turbulence walls are all located on one side of the thickness direction of the turbulence plate and are staggered along the height direction of the turbulence plate; the second, fifth, and sixth turbulence walls are all located on the other side of the thickness direction of the turbulence plate and are staggered along the height direction of the turbulence plate.
[0008] Compared with the prior art, the turbulence-disrupting plate described in this utility model has the following beneficial effects:
[0009] The baffles are installed inside the heat exchange tubes. On one side of the baffles' thickness direction, when the water flows through the first baffle orifice, it splits at the first baffle wall and flows above and below the baffles respectively. Then, when it flows through the second baffle orifice, it merges between the third and fourth baffle walls. On the other side of the baffles' thickness direction, when the water flows through the first baffle orifice, it splits at the second baffle wall and flows above and below the baffles respectively. Then, when it flows through the second baffle orifice, it merges between the fifth and sixth baffle walls. This allows the water flow inside the heat exchange tubes to split at the first baffle orifice, flow up and down, and then merge at the second baffle orifice. This improves the baffles' turbulence effect, increases the turbulence of the water flow inside the heat exchange tubes, keeps the water temperature inside the heat exchange tubes uniform, prevents excessively high water temperatures at the bottom of the heat exchange tubes, reduces scale formation, lowers vaporization noise, and improves the thermal conductivity of the heat exchange tubes.
[0010] In one embodiment, the first baffle wall and the second baffle wall have the same structure and are set at the same height;
[0011] The third, fourth, fifth, and sixth baffle walls have the same structure, and the third and sixth baffle walls are set at the same height, while the fourth and fifth baffle walls are set at the same height.
[0012] In one embodiment, the first spoiler wall is located at the middle position of the first sidewall along the height direction of the spoiler, and the second spoiler wall is located at the middle position of the second sidewall along the height direction of the spoiler.
[0013] The third and fourth baffle walls are spaced apart along the height direction of the baffle plate, with the third baffle wall located above the fourth baffle wall; the fifth and sixth baffle walls are spaced apart along the height direction of the baffle plate, with the fifth baffle wall located above the sixth baffle wall.
[0014] In one embodiment, the distance W between the third and fourth baffle walls along the height direction of the baffle plate is 9mm to 10mm.
[0015] In one embodiment, the lengths of the first and second baffle walls along the height direction of the baffle plate are both L, then W < L.
[0016] In one embodiment, the distance between the top end of the first turbulence wall and the first turbulence orifice is 5mm to 6mm, and the distance between the bottom end of the first turbulence wall and the first turbulence orifice is 5mm to 6mm.
[0017] In one embodiment, the first and second disturbance flow holes have the same structure, the distance between the top end of the disturbance flow hole and the top end of the disturbance plate is 2.5mm to 3mm, and the distance between the bottom end of the disturbance flow hole and the bottom end of the disturbance plate is 2.5mm to 3mm.
[0018] In one embodiment, the distance between adjacent first and second disturbance holes is 6 mm to 8 mm.
[0019] In one embodiment, a plurality of turbulence holes are spaced apart along the length of the top end and / or the bottom end of the turbulence plate, and the turbulence holes penetrate both sides of the thickness direction of the turbulence plate.
[0020] In one embodiment, the inner side of the turbulence hole is turned outward to form a turbulence section.
[0021] The second technical problem mentioned above is solved by the following technical solution:
[0022] A heat exchanger includes a heat exchange tube and the aforementioned baffles, wherein the baffles are installed inside the heat exchange tube along the axial direction of the heat exchange tube.
[0023] Compared with the prior art, the heat exchanger described in this utility model has the following advantages:
[0024] The baffles are installed inside the heat exchange tubes. On one side of the baffles' thickness direction, when the water flows through the first baffle orifice, it splits at the first baffle wall and flows above and below the baffles respectively. Then, when it flows through the second baffle orifice, it merges between the third and fourth baffle walls. On the other side of the baffles' thickness direction, when the water flows through the first baffle orifice, it splits at the second baffle wall and flows above and below the baffles respectively. Then, when it flows through the second baffle orifice, it merges between the fifth and sixth baffle walls. This allows the water flow inside the heat exchange tubes to split at the first baffle orifice, flow up and down, and then merge at the second baffle orifice. This improves the baffles' turbulence effect, increases the turbulence of the water flow inside the heat exchange tubes, keeps the water temperature inside the heat exchange tubes uniform, prevents excessively high water temperatures at the bottom of the heat exchange tubes, reduces scale formation, lowers vaporization noise, and improves the thermal conductivity of the heat exchange tubes.
[0025] In one embodiment, the six baffle walls—the first baffle wall, the second baffle wall, the third baffle wall, the fourth baffle wall, the fifth baffle wall, and the sixth baffle wall—have the same height along the thickness direction of the baffle plate, and the distance between the baffle wall and the inner wall of the heat exchange tube is 6 mm to 8 mm.

[0033] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0037] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0038] This embodiment proposes a heat exchanger, which is mainly used in gas water heaters. Of course, the heat exchanger can also be used in other equipment or products that require heat exchange, which will not be listed here. The heat exchanger includes components such as a burner and heat exchange tubes. The high-temperature flue gas generated by the burner passes through the heat exchange tubes, increasing the water flow within the tubes, thereby providing hot water to the user.
[0039] In this embodiment, as Figure 3 As shown, the heat exchange tube 100 is made of stainless steel instead of copper to reduce the cost of the heat exchange tube 100 and improve its corrosion resistance. At the same time, the round tube is designed as an elliptical tube or a racetrack-shaped flat tube with a larger heat exchange area to improve the heat exchange efficiency of the heat exchange tube 100.
[0040] Existing stainless steel heat exchange tubes have a low thermal conductivity. The inner wall temperature at the bottom (near the flue gas side) of the heat exchange tube is relatively high, while the water temperature at the top is relatively low. This leads to scale buildup at the bottom of the heat exchange tube during long-term use, reducing its thermal conductivity. Furthermore, excessively high inner wall temperatures can cause vaporization noise, accelerating scale formation and further reducing the heat exchange tube's thermal conductivity.
[0041] To solve the above problems, such as Figure 1 and Figure 2As shown, this embodiment also proposes a baffle plate 10. The baffle plate 10 is installed inside the heat exchange tube 100 along the axial direction (front-back direction in the figure). The baffle plate 10 has a first baffle flow hole 1 and a second baffle flow hole 2 that are staggered along the length direction (front-back direction in the figure) and penetrate both sides of the thickness direction (left-right direction in the figure). The first baffle flow hole 1 has a first sidewall and a second sidewall that are arranged opposite to each other along the length direction. The second baffle flow hole 2 has a third sidewall and a fourth sidewall that are arranged opposite to each other along the length direction. The first sidewall is turned outward to form a first baffle wall 3, the second sidewall is turned outward to form a second baffle wall, the third sidewall is turned outward to form a third baffle wall 4 and a fourth baffle wall 5, and the fourth sidewall is turned outward to form a fifth baffle wall and a sixth baffle wall. The first baffle wall 3, the third baffle wall 4, and the fourth baffle wall 5 are all located on one side of the thickness direction of the baffle plate 10 and are staggered along the height direction of the baffle plate 10 (up-down direction in the figure). The second, fifth, and sixth turbulence walls are all located on the opposite side of the thickness direction of the turbulence plate 10 and are staggered along the height direction of the turbulence plate 10.
[0042] When the baffle plate 10 is installed inside the heat exchange tube 100, on one side of the thickness direction of the baffle plate 10, when the water flows through the first baffle orifice 1, it is split at the first baffle wall 3 and flows to the top and bottom of the baffle plate 10 respectively. Then, when it flows through the second baffle orifice 2, it merges between the third baffle wall 4 and the fourth baffle wall 5. On the other side of the thickness direction of the baffle plate 10, when the water flows through the first baffle orifice 1, it is split at the second baffle wall and flows to the top and bottom of the baffle plate 10 respectively. Then, when it flows through the second baffle orifice 2, it merges between the fifth and sixth baffle walls. This makes the water flow in the heat exchange tube 100 split at the first baffle orifice 1 and flow up and down, and then merge at the second baffle orifice 2. This improves the baffle plate 10's turbulence effect, increases the turbulence of the water flow in the heat exchange tube 100, keeps the water temperature in the heat exchange tube 100 uniform, avoids excessively high water temperature at the bottom of the heat exchange tube 100, reduces scale formation and vaporization noise, and improves the thermal conductivity of the heat exchange tube 100.
[0043] When the baffle 10 is installed on the racetrack-shaped heat exchange tube 100, the baffle 10 divides the heat exchange tube 100 into left and right channels. The baffle 10 has multiple rectangular first baffle holes 1 and second baffle holes 2 spaced apart along its length, allowing the water flow in the left and right channels of the heat exchange tube 100 to flow and mix with each other through the first baffle holes 1 and the second baffle holes 2. This improves the turbulence effect within the heat exchange tube 100, ensures the uniformity of the water temperature within the heat exchange tube 100, and prevents the water temperature at the bottom of the heat exchange tube 100 from becoming too high. In addition, the sidewall of the first baffle hole 1 is flanged to form a first baffle wall 3 and a second baffle wall, and the sidewall of the second baffle hole 2 is flanged to form a third baffle wall 4, a fourth baffle wall 5, a fifth baffle wall, and a sixth baffle wall. This improves the processing efficiency of the baffle walls and reduces the cost of the baffle 10.
[0044] In one embodiment, the baffle plate 10 and the baffle wall can be made of copper or stainless steel. The first baffle wall 3, the second baffle wall, the third baffle wall 4, the fourth baffle wall 5, the fifth baffle wall, and the sixth baffle wall all have a flange angle of 90°, meaning they are perpendicular to the baffle plate 10. When the water flow in the heat exchange tube 100 moves from front to back, it collides and impacts with the six baffle walls, changing the direction of the water flow and improving the turbulence effect. In other embodiments, the flange angle of the six baffle walls can be other angles, as long as they achieve the desired turbulence effect.
[0045] like Figure 1 and Figure 2 As shown, on the left side of the baffle plate 10 in the thickness direction, multiple first baffle walls 3 are spaced apart in the front-to-back direction, multiple third baffle walls 4 are spaced apart in the front-to-back direction near the upper part of the heat exchange tube 100, and multiple fourth baffle walls 5 are spaced apart in the front-to-back direction near the lower part of the heat exchange tube 100. The first baffle walls 3, third baffle walls 4, and fourth baffle walls 5 are staggered in the vertical direction to form a transverse figure-eight flow channel on the left side of the baffle plate 10. Similarly, on the right side of the baffle plate 10 in the thickness direction, multiple second baffle walls are spaced apart in the front-to-back direction, multiple fifth baffle walls are spaced apart in the front-to-back direction near the upper part of the heat exchange tube 100, and multiple sixth baffle walls are spaced apart in the front-to-back direction near the lower part of the heat exchange tube 100. The second baffle walls, fifth baffle walls, and sixth baffle walls are staggered in the vertical direction to form a transverse figure-eight flow channel on the right side of the baffle plate 10.
[0046] like Figure 2As shown, taking the flow channel on the left side of the heat exchange tube 100 as an example, the water flows along the trajectory indicated by the arrow in the figure. The water flow in the heat exchange tube 100 is split by the first turbulence wall 3 and flows above and below the turbulence plate 10 respectively. Then, when it flows through the second turbulence orifice 2, it merges between the third turbulence wall 4 and the fourth turbulence wall 5. The merged water flow continues to flow to the next first turbulence wall 3, thus repeatedly achieving the splitting and merging of the flow. This effectively changes the flow state of the water in the heat exchange tube 100, increases turbulence, ensures uniform water temperature within the heat exchange tube 100, reduces vaporization noise, and minimizes scale formation. The flow situation on the right side of the heat exchange tube 100 is the same as on the left side and will not be described further here.
[0047] It should be noted that the first and second spoiler walls 3 have the same structure and are set at the same height. The third, fourth, fifth, and sixth spoiler walls have the same structure, and the third and fifth spoiler walls are set at the same height, as are the fourth and sixth spoiler walls. Therefore, in the first spoiler passage 1, the first and second spoiler walls are symmetrically distributed. In the second spoiler passage 2, the third and sixth spoiler walls are symmetrically distributed, and the fourth and fifth spoiler walls are symmetrically distributed. This simplifies the structure of the spoiler plate 10, facilitates its manufacturing, eliminates the need to select an installation direction, provides good error prevention, and improves the assembly efficiency of the spoiler plate 10.
[0048] In this embodiment, as Figures 1-3 As shown, the first turbulence wall 3 is located at the middle position of the first side wall along the height direction of the turbulence plate 10, and the second turbulence wall is located at the middle position of the second side wall along the height direction of the turbulence plate 10. The third turbulence wall 4 and the fourth turbulence wall 5 are spaced apart along the height direction of the turbulence plate 10, with the third turbulence wall 4 located above the fourth turbulence wall 5. The fifth turbulence wall and the sixth turbulence wall are spaced apart along the height direction of the turbulence plate 10, with the fifth turbulence wall located above the sixth turbulence wall. Because the third turbulence wall 4 and the fifth turbulence wall are set at the same height, and the fourth turbulence wall 5 and the sixth turbulence wall are set at the same height, gaps are formed between the third turbulence wall 4 and the fourth turbulence wall 5, and between the fifth turbulence wall and the sixth turbulence wall, reducing the water resistance inside the heat exchange tube 100.
[0049] like Figure 3As shown, the distance W between the third and fourth baffle walls 4 and 5 along the height direction of the baffle plate 10 is 9mm to 10mm. Since the third and fifth baffle walls are set at the same height, and the fourth and sixth baffle walls are set at the same height, the distance W between the fifth and sixth baffle walls along the height direction of the baffle plate 10 is also 9mm to 10mm. In this embodiment, the distance W can be 9mm, 9.2mm, 9.4mm, 9.6mm, 9.8mm, or 10mm, etc. If the distance W is too small, i.e., the gap between the third and fourth baffle walls 4 and the gap between the fifth and sixth baffle walls is small, the obstruction effect on the water flow is increased, thus increasing water resistance. If the distance W is too large, i.e., the gap between the third and fourth baffle walls 4 and the gap between the fifth and sixth baffle walls is too large, the obstruction effect of the four baffle walls on the water flow is significantly reduced, thus decreasing the turbulence effect.
[0050] Furthermore, the lengths of the first and second turbulence walls along the height of the turbulence plate 10 are both L, so W < L. This allows the water to flow towards the upper or lower part of the heat exchange tube 100 when it passes through the first turbulence wall 3 (or the second turbulence wall), and it will not flow horizontally towards the gap between the third and fourth turbulence walls 4 and 5 (or the gap between the fifth and sixth turbulence walls). This ensures sufficient turbulence effect on the water flow, achieves uniform water temperature in the upper and lower parts of the heat exchange tube 100, and improves vaporization noise.
[0051] like Figure 3 As shown, the distance D1 between the top end of the first turbulence wall 3 and the first turbulence orifice 1 is 5mm to 6mm, and the distance between the bottom end of the first turbulence wall 3 and the first turbulence orifice 1 is 5mm to 6mm. Similarly, the distance D1 between the top end of the second turbulence wall and the first turbulence orifice 1 is 5mm to 6mm, and the distance between the bottom end of the second turbulence wall and the first turbulence orifice 1 is 5mm to 6mm. In this embodiment, the distance D1 can be 5mm, 5.2mm, 5.4mm, 5.6mm, 5.8mm, or 5mm, etc., so that the first turbulence wall 3 and the second turbulence wall have a better blocking and diversion effect. If the distance D1 is too small, the area of the first turbulence wall 3 and the second turbulence wall is increased, thereby increasing the water resistance at the first turbulence wall 3 and the second turbulence wall. If the distance D1 is too large, the area of the first turbulence wall 3 and the second turbulence wall is reduced, and it is not possible to ensure that the water flow is fully diverted at the first turbulence wall 3 and the second turbulence wall, thus reducing the diversion and mixing effect of the water flow.
[0052] like Figure 3As shown, the distance D2 between adjacent first and second disturbance holes 1 and 2 is 6mm to 8mm. In this embodiment, the distance D2 can be 6mm, 6.5mm, 7mm, 7.5mm, or 8mm, etc., to ensure that the first and second disturbance holes 1 and 2 have a suitable distance, thereby controlling the number of disturbance holes and the structural strength of the disturbance plate 10, and improving the disturbance effect of the disturbance plate 10. If the distance D2 is too small, the number of disturbance holes will be too large and the distribution will be too dense, increasing water resistance. If the distance D2 is too small, the number of disturbance holes will be too small and the distribution will be sparse, reducing the disturbance effect.
[0053] like Figure 3 As shown, the first and second disturbance holes 1 and 2 have the same structure. The distance D3 between the top of the disturbance hole and the top of the disturbance plate 10 is 2.5mm to 3mm, and the distance between the bottom of the disturbance hole and the bottom of the disturbance plate 10 is 2.5mm to 3mm. In this embodiment, the distance D3 can be 2.5mm, 2.7mm, 2.9mm, or 3mm, etc. The length and width of the first and second disturbance holes 1 and 2 are the same. If the distance D3 is too large, the area of the first and second disturbance holes 1 and 2 will be small, and the water flow communication area in the channels on both sides of the heat exchange tube 100 will decrease, thereby reducing the mixing and disturbance effect of the water flow on both sides of the heat exchange tube 100. If the spacing D3 is too large, the two disturbance holes, the first disturbance hole 1 and the second disturbance hole 2, are too close to the top and bottom edges of the disturbance plate 10. During the processing of the first disturbance hole 1 and the second disturbance hole 2, the disturbance plate 10 is prone to deformation, which reduces the structural strength of the disturbance plate 10.
[0054] It should be noted that the six baffle walls—the first baffle wall 3, the second baffle wall, the third baffle wall 4, the fourth baffle wall 5, the fifth baffle wall, and the sixth baffle wall—have equal heights along the thickness direction of the baffle plate 10, and the distance between the baffle walls and the inner wall of the heat exchange tube 100 is 6mm to 8mm. The distance between the baffle walls and the inner wall of the heat exchange tube 100 can be 6mm, 6.5mm, 7mm, 7.5mm, or 8mm, etc., which reduces the water resistance inside the heat exchange tube 100 while increasing the contact area between the baffle walls and the water flow, thus enhancing the turbulence effect.
[0055] In one embodiment, such as Figure 4As shown, the top and / or bottom of the baffle plate 10 are provided with a plurality of baffle holes 6 spaced apart along the length direction, and the baffle holes 6 penetrate both sides of the baffle plate 10 in the thickness direction. By setting the baffle holes 6, the left and right sides of the upper part of the heat exchange tube 100 are connected through the baffle holes 6 in the upper part of the heat exchange tube 100, and the left and right sides of the lower part of the heat exchange tube 100 are connected through the baffle holes 6 in the lower part of the heat exchange tube 100, so that the water flow on the left and right sides of the heat exchange tube 100 is fully mixed, which enhances the water temperature uniformity between the upper and lower parts of the heat exchange tube 100 and further improves the baffle effect.
[0056] Specifically, the top end of the deflector 10 is provided with a plurality of deflection holes 6 spaced apart along its length. The top end of the deflector 10 is recessed inward to form a semi-circular deflection hole 6, and the plurality of deflection holes 6 and the plurality of deflection orifices are staggered along the front-back direction. Simultaneously, the bottom end of the deflector 10 is provided with a plurality of deflection holes 6 spaced apart along its length. The bottom end of the deflector 10 is recessed inward to form a semi-circular deflection hole 6, and the plurality of deflection holes 6 and the plurality of deflection orifices are staggered along the front-back direction, so that there is a deflection hole 6 at both the top and bottom of adjacent deflection orifices, increasing the density of the deflection structure of the deflector 10 along the front-back direction, thereby enhancing the deflection effect of the deflector 10. At the same time, the deflection holes 6 do not interfere with the deflection orifices, facilitating the manufacturing of the deflection holes 6. In other embodiments, a row of deflection holes 6 may be provided only at the top end or the bottom end of the deflector 10.
[0057] In one embodiment, such as Figure 5 As shown, the inner side of the turbulence hole 6 is turned outward to form a turbulence section 7. In this embodiment, the turbulence section 7 is a turbulence-turned-edge structure. The inner edge of the turbulence hole 6 is turned outward to the left or right in the thickness direction of the turbulence plate 10 to form an arc-shaped turbulence section 7, which further increases the turbulence effect of the upper and lower parts of the heat exchange tube 100.
[0058] Specifically, at the top of the spoiler 10, two adjacent spoiler parts 7 are located on the left and right sides of the spoiler 10, respectively. At the bottom of the spoiler 10, two adjacent spoiler parts 7 are located on the left and right sides of the spoiler 10, and two vertically opposite spoiler parts 7 are located on the left and right sides of the spoiler 10, respectively.
[0059] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
