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. Since the thermal conductivity of stainless steel is significantly lower than that of pure copper, the traditional round tube shape of the heat exchange tube is usually designed as an elliptical tube or a racetrack-shaped flat tube with a larger heat exchange area.
[0003] Because stainless steel heat exchange tubes have a low thermal conductivity, the inner wall temperature at the bottom (near the flue gas side) 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 tubes over long-term use, reducing their thermal conductivity. Furthermore, excessively high inner wall temperatures can cause vaporization noise, accelerating scale formation and further reducing the tubes' thermal conductivity. Utility Model Content
[0004] 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.
[0005] 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.
[0006] The first technical problem mentioned above is solved by the following technical solution:
[0007] A baffle plate, wherein a plurality of baffle holes are spaced apart along the length direction, the baffle holes penetrate both sides of the baffle plate in the thickness direction, and the baffle holes have a first sidewall and a second sidewall disposed opposite to each other along the length direction;
[0008] The first sidewall is turned outward to form at least one set of first and second baffle walls, and the second sidewall is turned outward to form at least one set of third and fourth baffle walls. The first and third baffle walls are both located on one side of the thickness direction of the baffle and are staggered along the height direction of the baffle. The second and fourth baffle walls are both located on the other side of the thickness direction of the baffle and are staggered along the height direction of the baffle.
[0009] Compared with the prior art, the turbulence-disrupting plate described in this utility model has the following beneficial effects:
[0010] The turbulence-inducing vanes are installed inside the heat exchange tubes. The first and third turbulence-inducing walls on one side of the turbulence-inducing vane's thickness direction are staggered along the height direction of the turbulence-inducing vane, while the second and fourth turbulence-inducing walls on the other side of the turbulence-inducing vane's thickness direction are staggered along the height direction of the turbulence-inducing vane, thus forming S-shaped flow channels on both sides of the turbulence-inducing vane's thickness direction. The water flow inside the heat exchange tubes flows alternately up and down in the S-shaped flow channels along the height direction of the turbulence-inducing vane, which improves the turbulence effect and increases the turbulence of the water flow. This keeps the water temperature inside the heat exchange tubes uniform and avoids excessively high water temperature at the bottom of the heat exchange tubes, reduces scale formation and vaporization noise, and improves the thermal conductivity of the heat exchange tubes.
[0011] In one embodiment, the first, second, third, and fourth baffle walls are four baffle walls with identical structures, and the first and fourth baffle walls are set at the same height, while the second and third baffle walls are set at the same height.
[0012] In one embodiment, the first and second baffle walls are spaced apart along the height direction of the baffle plate, with the first baffle wall located above the second baffle wall; the third and fourth baffle walls are spaced apart along the height direction of the baffle plate, with the fourth baffle wall located above the third baffle wall.
[0013] In one embodiment, the distance between the first baffle wall and the second baffle wall along the height direction of the baffle plate is 4mm to 5mm.
[0014] In one embodiment, the distance between the top of the first baffle wall and the baffle plate along the height direction of the baffle plate is 3mm to 4mm.
[0015] 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.
[0016] In one embodiment, the inner side of the turbulence hole is turned outward to form a turbulence section.
[0017] The second technical problem mentioned above is solved by the following technical solution:
[0018] 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.
[0019] Compared with the prior art, the heat exchanger described in this utility model has the following advantages:
[0020] The turbulence vanes are installed inside the heat exchange tubes. The water flow inside the heat exchange tubes flows alternately up and down along the height of the turbulence vanes in the S-shaped flow channel, which improves the turbulence effect and increases the turbulence of the water flow. This keeps the water temperature inside the heat exchange tubes uniform, prevents the water temperature at the bottom of the heat exchange tubes from being too high, reduces scale formation, lowers vaporization noise, and improves the thermal conductivity of the heat exchanger.
[0021] In one embodiment, the distance between the end of the first turbulence wall away from the turbulence plate and the inner wall of the heat exchange tube is 1.5 mm to 2 mm.
[0022] In one embodiment, the distance between the first turbulence wall on the turbulence plate and the water inlet of the heat exchange tube is 7mm to 10mm. Attached Figure Description

It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it.

[0034] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0035] 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.
[0036] like Figure 1 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.
[0037] 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.
[0038] To solve the above problems, such as Figure 2 and Figure 3 As shown, this embodiment also proposes a baffle plate 10, which is installed axially within the heat exchange tube 100. The baffle plate 10 has multiple baffle holes 1 spaced apart along its length (front-back direction in the figure), and the baffle holes 1 penetrate both sides of the baffle plate 10 in its thickness direction (left-right direction in the figure). Each baffle hole 1 has a first sidewall and a second sidewall arranged opposite to each other along its length. The first sidewall is turned outwards to form at least one set of first baffle walls 2 and second baffle walls 3, and the second sidewall is turned outwards to form at least one set of third baffle walls 4 and fourth baffle walls 5. The first baffle walls 2 and 4 are both located on one side of the baffle plate 10 in its thickness direction and are staggered along the height direction of the baffle plate 10 (up-down direction in the figure). The second baffle walls 3 and 5 are both located on the other side of the baffle plate 10 in its thickness direction and are staggered along the height direction of the baffle plate 10. By installing the baffle plate 10 inside the heat exchange tube 100, the first baffle wall 2 and the third baffle wall 4 located on one side of the thickness direction of the baffle plate 10 are staggered along the height direction of the baffle plate 10, and the second baffle wall 3 and the fourth baffle wall 5 located on the other side of the thickness direction of the baffle plate 10 are staggered along the height direction of the baffle plate 10, so that S-shaped flow channels are formed on both sides of the thickness direction of the baffle plate 10. The water flow in the heat exchange tube 100 flows up and down alternately in the S-shaped flow channels along the height direction of the baffle plate 10, which improves the turbulence effect and increases the turbulence of the water flow, so as to keep the water temperature in the heat exchange tube 100 uniform and consistent, avoid the water temperature at the bottom of the heat exchange tube 100 from being too high, reduce the formation of scale and reduce vaporization noise, and improve the thermal conductivity of the heat exchange tube 100.
[0039] like Figure 1 and Figure 2 As shown, 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 baffle holes 1 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 baffle holes 1. 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, four baffle walls are formed on the first and second sides of the baffle holes 1 by flanges, which improves the processing efficiency of the baffle walls and reduces the cost of the baffle 10.
[0040] In one embodiment, the baffle plate 10 and the baffle walls can be made of copper or stainless steel. The flange angles of the four baffle walls—the first baffle wall 2, the second baffle wall 3, the third baffle wall 4, and the fourth baffle wall 5—are all 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 four baffle walls, changing the direction of the water flow and improving the turbulence effect. In other embodiments, the flange angles of the four baffle walls can be other angles, as long as they achieve the desired turbulence effect.
[0041] like Figure 1 and Figure 3 As shown, on the left side of the baffle plate 10, multiple first baffle walls 2 are spaced apart near the upper part of the heat exchange tube 100 in the front-back direction, and multiple third baffle walls 4 are spaced apart near the lower part of the heat exchange tube 100 in the front-back direction. The first baffle walls 2 and the third baffle walls 4 are staggered in the front-back direction to form an S-shaped flow channel on the left side of the baffle plate 10. Similarly, on the right side of the baffle plate 10, multiple fourth baffle walls 5 are spaced apart near the upper part of the heat exchange tube 100 in the front-back direction, and multiple second baffle walls 3 are spaced apart near the lower part of the heat exchange tube 100 in the front-back direction. The fourth baffle walls 5 and the second baffle walls 3 are staggered in the front-back direction to form an S-shaped flow channel on the right side of the baffle plate 10.
[0042] like Figure 3 As shown, taking the S-shaped flow channel on the right side inside heat exchanger tube 100 as an example, the water flows along... Figure 3 As indicated by the middle arrow, the water flow at the bottom of heat exchange tube 100 flows upward under the obstruction of the second turbulence wall 3, while the water flow at the top of heat exchange tube 100 flows downward under the obstruction of the fourth turbulence wall 5. Then, after mixing in the middle of heat exchange tube 100, the water continues to flow in a cyclical pattern along the S-shaped flow channel, alternating between upward and downward flow. This effectively changes the flow state within heat exchange tube 100, increasing turbulence, reducing the inner wall temperature at the bottom of heat exchange tube 100, ensuring uniform water temperature within heat exchange tube 100, reducing vaporization noise, and minimizing scale formation. The flow pattern on the left side of heat exchange tube 100 is the same as on the right side and will not be described further.
[0043] It should be noted that the first baffle wall 2, the second baffle wall 3, the third baffle wall 4, and the fourth baffle wall 5 are four baffle walls with identical structures. The first baffle wall 2 and the fourth baffle wall 5 are set at the same height, and the second baffle wall 3 and the third baffle wall 4 are set at the same height. Because the four baffle walls have identical structures and are arranged in pairs, the first baffle wall 2 and the fourth baffle wall 5 are symmetrically distributed within the same baffle passage 1, and the second baffle wall 3 and the third baffle wall 4 are symmetrically distributed. This simplifies the structure of the baffle plate 10, facilitates its manufacturing, eliminates the need to select an installation direction, provides good error prevention, and improves the assembly efficiency of the baffle plate 10. Furthermore, the identical structure of the four baffle walls ensures consistent baffle effects and guarantees uniform baffle flow.
[0044] In this embodiment, as Figure 1 and Figure 2 As shown, the first baffle wall 2 and the second baffle wall 3 are spaced apart along the height direction of the baffle plate 10, with the first baffle wall 2 located above the second baffle wall 3. The third baffle wall 4 and the fourth baffle wall 5 are spaced apart along the height direction of the baffle plate 10, with the fourth baffle wall 5 located above the third baffle wall 4. Because the first baffle wall 2 and the fourth baffle wall 5 are set at the same height, and the second baffle wall 3 and the third baffle wall 4 are set at the same height, gaps are formed between the first baffle wall 2 and the third baffle wall 4, and between the second baffle wall 3 and the fourth baffle wall 5, reducing the water resistance inside the heat exchange tube 100.
[0045] In this embodiment, the distance D1 between the top of the first baffle wall 2 and the top of the baffle plate 10 along the height direction of the baffle plate 10 is 3mm to 4mm. Since the first baffle wall 2 and the fourth baffle wall 5 are set at the same height, the distance D1 between the top of the fourth baffle wall 5 and the top of the baffle plate 10 along the height direction of the baffle plate 10 is also the same. Similarly, the distance D1 between the second baffle wall 3 and the third baffle wall 4 and the bottom of the baffle plate 10 along the height direction of the baffle plate 10 is also the same. In this embodiment, the distance D1 can be 3mm, 3.2mm, 3.4mm, 3.6mm, 3.8mm, or 4mm, etc., to ensure the manufacturability and structural strength of the baffle wall. If the distance D1 is too small, the baffle wall will be too close to the top or bottom of the baffle plate 10, causing deformation of the baffle plate 10 during the processing of the baffle wall, increasing the difficulty of manufacturing. If the spacing D1 is too large, the distance between the spoiler wall and the top or bottom of the spoiler 10 will be too far, which will increase the height of the spoiler 10 and limit the installation of the spoiler 10.
[0046] Furthermore, such as Figure 1As shown, the distance D2 between the first baffle wall 2 and the second baffle wall 3 along the height direction of the baffle plate 10 is 4mm to 5mm. In this embodiment, the distance D2 can be 4mm, 4.2mm, 4.4mm, 4.6mm, 4.8mm, or 5mm, etc. If the distance D2 is too small, that is, the gap between the first baffle wall 2 and the third baffle wall 4, and the gap between the second baffle wall 3 and the fourth baffle wall 5 are small, the obstruction effect on the water flow is increased, thereby increasing the water resistance. If the distance D2 is too large, that is, the gap between the first baffle wall 2 and the third baffle wall 4, and the gap between the second baffle wall 3 and the fourth baffle wall 5 are large, the obstruction effect of the baffle wall on the water flow is significantly reduced, thus reducing the turbulence effect.
[0047] like Figure 1 As shown, the distance D3 between the end of the first turbulence wall 2 furthest from the turbulence plate 10 and the inner wall of the heat exchange tube 100 is 1.5mm to 2mm. It can be understood that the distances D3 between the second turbulence wall 3, the third turbulence wall 4, and the fourth turbulence wall 5 and the inner wall of the adjacent heat exchange tube 100 are all D3. In this embodiment, the distance D3 can be 1.5mm, 1.7mm, 1.9mm, or 2mm, etc., to reduce the water resistance inside the heat exchange tube 100 while increasing the contact area between the turbulence wall and the water flow, thus increasing the turbulence effect. If the distance D3 is too small, the contact area between the turbulence wall and the water flow is small, reducing the turbulence effect; if the distance D3 is too large, the gap between the turbulence wall and the inner wall of the heat exchange tube 100 becomes smaller, increasing the water resistance inside the heat exchange tube 100.
[0048] like Figure 3 As shown, the distance D4 between the first turbulence wall on the turbulence plate 10 and the water inlet of the heat exchange tube 100 is 7mm to 10mm. In this embodiment, the distance D4 can be 7mm, 8mm, 9mm or 10mm, etc., to reduce the obstruction effect of the turbulence wall on the water flow at the water inlet of the heat exchange tube 100, thereby reducing the water resistance at the water inlet of the heat exchange tube 100 and ensuring smooth water flow.
[0049] In one embodiment, such as Figure 4 As 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.
[0050] 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 flow holes 1 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 flow holes 1 are staggered along the front-back direction, so that there is a deflection hole 6 at both the top and bottom of adjacent deflection flow holes 1, 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 flow holes 1, 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.
[0051] 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.
[0052] 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.
[0053] 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.
