Description

Technical Field

[0001] This utility model belongs to the field of heat exchanger technology, and specifically provides a heat exchanger and an air conditioner. Background Technology

[0002] In the field of heat exchangers, fins are widely used as an important heat transfer element. Common fin types include straight fins, corrugated fins, louvered fins, and perforated fins, whose main function is to increase the heat transfer area and improve heat transfer efficiency. For example, in the heat exchanger of an air conditioner, the performance of the fins directly affects the energy efficiency and performance of the air conditioner.

[0003] Existing fins typically include a fin body and a clamping section, so that the fins are thermally connected to the refrigerant pipes through the clamping section, and exchange heat with the gas flowing through them mainly through the fin body.

[0004] Existing corrugated fins typically feature alternating crests and troughs in the fin body. This increases the heat exchange area of ​​the fins while enhancing the structural strength of the fin body and turbulentizing the airflow passing through it, thus disrupting the boundary layer formed on the fin surface. It's important to note that the boundary layer separates other air from the fins, forcing other air to exchange heat indirectly with the fins only through the boundary layer, thereby affecting the heat exchanger's efficiency.

[0005] However, existing heat exchangers do not consider the relationship between fin spacing and wave crests, resulting in poor overall heat exchange and air resistance performance. Utility Model Content

[0006] One objective of this invention is to solve the problem of poor overall performance of existing heat exchangers.

[0007] To achieve the above objectives, the present invention provides a heat exchanger in a first aspect, comprising a plurality of fins and a refrigerant pipe penetrating the plurality of fins.

[0008] The fin includes a fin body and an M-row of clamps disposed on the fin body, wherein the clamps are penetrated by the refrigerant pipe and thermally connected to the refrigerant pipe.

[0009] The fin portion includes M×N wave peaks, the height of each wave peak is H, and the distance between two adjacent fins is S.

[0010]

[0011] Where M and N are both natural numbers not less than 1.

[0012] Optionally, each column of the pipe clamps corresponds to N wave peaks, and each column of the pipe clamps is located on the midline of its corresponding N wave peaks.

[0013] Optionally, the slopes of the windward and leeward slopes of each of the aforementioned crests are different.

[0014] Optionally, in the windward and leeward slopes of the same wave crest, the slope of the slope furthest from the midline is greater than the slope of the slope closest to the midline.

[0015] Optionally, N ≥ 2, and the heights of the peaks are different.

[0016] Optionally, the height of at least one of the N wave peaks is greater than the height of the clamp portion, and / or, the height of at least one of the N wave peaks is less than the height of the clamp portion.

[0017] Optionally, M≥2, a connecting plate segment is provided between at least two adjacent crests between two adjacent columns of the clamp section.

[0018] Optionally, the connecting plate segment is perpendicular to the axis of the pipe clamp; and / or, the connecting plate segment is provided with a concave-convex structure to disrupt the boundary layer on the surface of the connecting plate segment where the airflow adheres.

[0019] Optionally, 2≤N≤4; and / or, the sheet portion further includes an upstream edge plate segment and a downstream edge plate segment, the upstream edge plate segment and the downstream edge plate segment being perpendicular to the axis of the pipe clamp portion; and the upstream edge plate segment and the downstream edge plate segment are respectively provided with concave and convex structures to disrupt the boundary layer on the surface of the upstream edge plate segment and the downstream edge plate segment where the airflow adheres.

[0020] The present invention provides an air conditioner in a second aspect, comprising the heat exchanger described in any one of the first aspects.

[0021] Those skilled in the art will understand that the presence of wave crests on the fins creates a reciprocating, zigzagging airflow channel between adjacent fins. If the airflow channel is too narrow, the wave crests will intensify the obstruction of airflow, increasing wind resistance. If the airflow channel is too wide, the wave crests will have a poorer turbulence effect on the airflow, resulting in poor heat exchange performance. In the aforementioned technical solution of this utility model, by ensuring that the spacing between the tube clamps, wave crests, and fins satisfies the above formula, both excessively small and excessively large spacing between fins are avoided. This ensures that the spacing between fins is coordinated with the number of wave crests in the fin body, improving the overall performance of the heat exchanger.

[0022] Furthermore, by ensuring that each column of pipe clamps is located on the midline of its corresponding N peaks, the fins can uniformly receive heat or cold from the refrigerant pipes.

[0023] Furthermore, by making the slopes of the windward and leeward slopes of each wave crest different, the amount of disturbance to the airflow along its flow path varies, thereby ensuring the stability of the airflow while disturbing it, and avoiding excessive wind noise.

[0044] Those skilled in the art should understand that the embodiments described below are merely some embodiments of the present invention, and not all embodiments of the present invention. These embodiments are intended to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by those skilled in the art without creative effort should still fall within the scope of protection of the present invention.

[0045] It should be noted that in the description of this utility model, terms such as "center," "upper," "lower," "top," "bottom," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the corresponding device or element 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. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0046] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. For example, unless otherwise specified, the terms "installation," "connection," "joining," and "fixing" can specifically refer to any feasible connection form such as bolt connection, screw connection, welding, insertion, riveting, fusion welding, or snap-fit.

[0047] Furthermore, it should be noted that in the description of this utility model, mm represents millimeter, cm represents centimeter, and m represents meter.

[0048] Furthermore, it should be noted that in the description of this utility model, the terms "coldness" and "heat" are two descriptions of the same physical state. That is, the higher the "coldness" of a target object (e.g., evaporator, air, condenser, etc.), the lower its "heat," and vice versa. A target object absorbs "coldness" while releasing "heat," and releases "coldness" while absorbing "heat." A target object retains "coldness" or "heat" to maintain its current temperature. "Refrigeration" and "heat absorption" are two descriptions of the same physical phenomenon; that is, a target object (e.g., evaporator) absorbs heat while refrigerating.

[0049] like Figure 1 and Figure 2 As shown, the heat exchanger 001 of this utility model includes multiple fins 100 and refrigerant pipes 200 passing through the multiple fins 100. The refrigerant pipes 200 are thermally connected to the fins 100, specifically by contacting each other and fixing them together by means of clamping, welding, etc., so that heat can be transferred between the refrigerant pipes 200 and the fins 100. That is, heat can be conducted from the refrigerant pipes 200 to the fins 100, or from the fins 100 to the refrigerant pipes 200.

[0050] In some embodiments of this utility model, the diameter of the refrigerant pipe 200 can be selected from any value between 5.8mm and 6.5mm, specifically any feasible value such as 5.8mm, 5.85mm, 5.9mm, 6.0mm, 6.01mm, 6.2mm, 6.3mm, and 6.5mm. Furthermore, the pipe diameter can be the size of the refrigerant pipe 200 before assembly with the fins 100, or the size after assembly with the fins 100.

[0051] Furthermore, the diameter of the refrigerant pipe 200 can be selected from any value between 5.9mm and 6.2mm, specifically any feasible value such as 5.9mm, 5.95mm, 5.98mm, 6.0mm, 6.03mm, 6.0mm, 6.05mm, 6.08mm, 6.12mm, 6.15mm, 6.2mm, etc.

[0052] like Figures 3 to 10 As shown, in some embodiments of this utility model, the fin 100 includes a fin body 110 and an M-row of clamp portions 120 disposed on the fin body 110. The clamp portions 120 are penetrated by a refrigerant pipe 200 and thermally connected to the refrigerant pipe 200. The clamp portions 120 are provided with a through hole 121 through which the refrigerant pipe 200 passes, so that the refrigerant pipe 200 passes through the clamp portions 120.

[0053] Furthermore, the sheet portion 110 includes M×N peaks 111, and the height of the peaks 111 is H (e.g., Figure 5 As shown), the spacing between two adjacent fins 100 is S (as shown). Figure 7 (as shown), then

[0054]

[0055] Where M and N are both natural numbers not less than 1.

[0056] Furthermore, M can be any feasible value such as 1, 2, 3, 4, 5, etc., and N can be any feasible value such as 1, 2, 3, 4, 5, etc.

[0057] For example, M is 1 or 2: N≥2, and specifically it can also be 2≤N≤4.

[0058] Those skilled in the art will understand that, due to the presence of wave crests 111 on the fin 100, a reciprocatingly bent airflow channel 102 will be formed between two adjacent fins 100 (e.g., Figure 7(As shown). If the airflow channel 102 is too narrow, the obstruction of the airflow by the wave crests 111 will be aggravated, and the wind resistance will increase. If the airflow channel 102 is too wide, the disturbance effect of the wave crests 111 on the airflow will be poor, and the heat exchange performance of the heat exchanger 001 will also be poor. In this utility model, by making the pipe clamp portion 120 on the fin 100, the wave crests 111 and the distance S between the fins 100 satisfy the above formula, it avoids that the distance S between the fins 100 is too small or too large, so that the distance S between the fins 100 is coordinated with the number of wave crests 111 of the fin portion 110, thereby improving the overall performance of the heat exchanger 001.

[0059] like Figure 3 As shown, in the same column, the pipe spacing J (axial distance) between two adjacent pipe clamp sections 120 is selected from any value between 17.2mm and 22mm. Specifically, the pipe spacing J can be any feasible value such as 17.2mm, 17.5mm, 18.1mm, 18.6mm, 19.1mm, 19.55mm, 19.8mm, 20.0mm, 20.3mm, 20.7mm, 20.9mm, 21.3mm, 21.8mm, 22mm, etc.

[0060] Continue reading Figure 3 The width L of the sheet portion 110 is selected from any value between 18mm and 22mm. Specifically, it can be any feasible value such as 18mm, 18.1mm, 18.6mm, 19.1mm, 19.55mm, 19.8mm, 20.0mm, 20.3mm, 20.5mm, 21mm, 21.3mm, 21.8mm, 22mm, etc.

[0061] Furthermore, 0.8 ≤ J / L ≤ 1.22, and the ratio of J to L can be any feasible value such as 0.8, 0.85, 0.9, 0.95, 1.1, 1.15, 1.2, 1.22, etc.

[0062] like Figure 3 and Figure 4 As shown, in some embodiments of this utility model, each column of pipe clamps 120 corresponds to N peaks 111, and each column of pipe clamps 120 is located on the midline 101 of its corresponding N peaks 111.

[0063] Those skilled in the art will understand that by positioning each column of pipe clamps 120 on the midpoint 101 of its corresponding N peaks 111, the fins 100 can uniformly receive heat or cold from the refrigerant pipes 200.

[0064] Furthermore, in some embodiments of this utility model, the slopes of the windward slope 1111 and the leeward slope 1112 of each wave crest 111 are different.

[0065] Optionally, in the windward slope 1111 and leeward slope 1112 of the same wave crest 111, the slope of the slope farther from the midline 101 is greater than the slope of the slope closer to the midline 101.

[0066] Furthermore, when N≥2, the heights of each peak 111 can be different. Also, the height of at least one of the N peaks 111 is greater than the height of the clamp portion 120, and / or, the height of at least one of the N peaks 111 is less than the height of the clamp portion 120.

[0067] The following reference Figures 5 to 12 Let's illustrate with an example.

[0068] exist Figures 5 to 7 In the example shown, the height of the left peak 111 is greater than the height of the right peak 111. Of course, those skilled in the art can also make the height of the left peak 111 smaller than the height of the right peak 111 as needed.

[0069] Furthermore, if the wind comes from Figure 7 left side Figure 7 When the wind speed on the inlet side is high, such as when the wind speed is greater than 5 m / s, the height of the left wave crest 111 is greater than the height of the right wave crest 111. When the wind speed on the inlet side is low, such as when the wind speed is less than or equal to 5 m / s, the height of the left wave crest 111 is less than the height of the right wave crest 111.

[0070] like Figures 5 to 7 As shown, the height of the left wave crest 111 is greater than the height h of the clamp portion 120, and the height of the right wave crest 111 is less than the height h of the clamp portion 120, so that the airflow can be gradually disturbed by the left wave crest 111, the right wave crest 111, and the clamp portion 120. This not only makes full use of the characteristics of each part of the fin 100 structure, but also allows the left wave crest 111 or the right wave crest 111 to protect the clamp portion 120, preventing the clamp portion 120 from being squeezed and deformed during production, manufacturing, transportation, and assembly.

[0071] like Figure 5 As shown, let H1 be the term with the larger height H between the left and right peaks 111, and H2 be the term with the smaller height H between the left and right peaks 111. Then, H1 and H2 have the following relationship:

[0072] 1≤H1 / H2≤2.5.

[0073] Specifically, the ratio of H1 to H2 can be any feasible value such as 1, 2.2, 1.35, 1.5, 1.7, 1.9, 2, 2.1, 2.3, 2.5, etc.

[0074] Those skilled in the art will understand that by making the ratio of H1 to H2 satisfy the above conditions, the left wave crest 111 and the right wave crest 111 can cause multiple disturbances to the airflow, and the disturbance effect of the right wave crest 111 on the airflow is ensured.

[0075] Furthermore, 1.1≤H1 / H2≤2, to avoid generating significant wind noise due to the large height difference between the left and right wave crests 111.

[0076] like Figure 5 As shown, in some embodiments of this utility model, the slope β1 of the windward slope section 1111 of the left wave crest 111 is greater than the slope β2 of the leeward slope section 1112 of the left wave crest 111.

[0077] Those skilled in the art will understand that by making the slope β1 of the windward slope 1111 of the left wave crest 111 of the plate portion 110 greater than the slope β2 of the leeward slope 1112 of the left wave crest 111, the windward slope 1111 of the left wave crest 111 has sufficient slope to significantly alter the direction of the airflow adhering to the surface of the plate portion 110, thus creating a turbulence effect. At the same time, it avoids the formation of vortices when the airflow crosses the wave crest 111 due to the excessive slope of the leeward slope 1112, which would prevent the airflow from being properly guided by the leeward slope 1112. Therefore, the fin 100 of this invention effectively reduces wind resistance.

[0078] Continue reading Figure 5 In some embodiments of this utility model, the slope β3 of the leeward slope section 1112 of the right wave crest 111 is greater than or less than the slope β4 of the windward slope section 1111 of the right wave crest 111.

[0079] Furthermore, 15°≤β1≤25°, 5°≤β2≤23°.

[0080] Accordingly, 15°≤β3≤25°, 5°≤β4≤23°.

[0081] Specifically, β1 can be any feasible value such as 15°, 17°, 18.5°, 20°, 21°, 23°, 25°, etc. β2 can be any feasible value such as 5°, 7°, 8.5°, 10°, 11°, 13°, 15°, 17°, 19°, 20°, 23°, etc. β3 can be any feasible value such as 15°, 17°, 18.5°, 20°, 21°, 23°, 25°, etc. β4 can be any feasible value such as 5°, 7°, 8.5°, 10°, 11°, 13°, 15°, 17°, 19°, 20°, 23°, etc.

[0082] like Figure 5As shown, on a plane perpendicular to the axis of the clamp portion 120, the length L11 of the projection of the left wave crest 111 away from the clamp portion 120 is less than the length L12 of the projection of the left wave crest 111 near the clamp portion 120. This results in a larger slope β1 on the side of the left wave crest 111 away from the clamp portion 120 and a smaller slope β2 on the side of the left wave crest 111 near the clamp portion 120. In this way, while ensuring that the fin 100 has sufficient width, the side of the left wave crest 111 away from the clamp portion 120 can significantly change the direction of the airflow attached to the surface of the fin portion 110, thus enhancing the turbulence effect.

[0083] Continue reading Figure 5 On a plane perpendicular to the axis of the clamp 120, the length L21 of the projection of the right wave crest 111 away from the clamp 120 can be made smaller than the length L22 of the projection of the right wave crest 111 close to the clamp 120.

[0084] like Figures 5 to 7 As shown, in some embodiments of this utility model, the sheet portion 110 further includes an upstream edge plate segment 112 and a downstream edge plate segment 113, which are perpendicular to the axis of the clamp portion 120. The upstream edge plate segment 112 and the downstream edge plate segment 113 are used to guide airflow.

[0085] like Figure 5 As shown, the upstream edge plate segment 112 and the downstream edge plate segment 113 can be of equal length and are both denoted as L3. The L3 is selected from any value from 0mm to 5mm, such as any feasible value such as 0mm, 0.5mm, 1mm, 1.2mm, 1.5mm, 1.8mm, 2mm, 2.5mm, 3mm, 4mm, 4.7mm, 5mm, etc.

[0086] Then L11, L12, L21, L22, L3, and L satisfy the following functional relationship:

[0087] 0.1(L-2·L3)≤L11≤0.24(L-2·L3), 0.26(L-2·L3)≤L12≤0.4(L-2·L3), 0.1(L-2·L3)≤L21≤0.24(L-2·L3), 0.26(L-2·L3)≤L22≤0.4(L-2·L3).

[0088] Those skilled in the art will understand that the above-mentioned relationship between L11, L12, L21, L22, L3 and L ensures that the sheet portion 110 has sufficient width while also ensuring that the crest section 111 has a suitable slope on both sides to disturb the airflow attached to the surface of the sheet portion 110.

[0089] Specifically, L11 can be any feasible value such as 0.1L, 0.15L, 0.18L, 0.2L, 0.225L, 0.24L, etc. L12 can be any feasible value such as 0.26L, 0.28L, 0.31L, 0.37L, 0.385L, 0.4L, etc. L21 can be any feasible value such as 0.1L, 0.15L, 0.18L, 0.2L, 0.225L, 0.24L, etc. L22 can be any feasible value such as 0.26L, 0.28L, 0.31L, 0.37L, 0.385L, 0.4L, etc.

[0090] Furthermore, those skilled in the art may, as needed, provide the upstream edge plate segment 112 and the downstream edge plate segment 113 with concave and convex structures (not shown in the figure) to disrupt the boundary layer on the surface of the airflow adhering to the upstream edge plate segment 112 and the downstream edge plate segment 113.

[0091] like Figure 8 As shown in the example, M=1, N=3. That is, the sheet portion 110 has one row of clamp portions 120 and three crests 111. The dimensional parameters of the crests 111 of the sheet portion 110 can be compared with... Figures 5 to 7 The peak 111 in the example shown may be the same or different.

[0092] like Figure 9 As shown in the example, M = 1, N = 4. That is, the sheet portion 110 has one row of clamp portions 120 and four crests 111. The dimensional parameters of the crests 111 of the sheet portion 110 can be compared with... Figures 5 to 7 The peak 111 in the example shown may be the same or different.

[0093] like Figure 10 As shown in the example, M=2, N=2. That is, the sheet portion 110 has two rows of clamp portions 120 and two crests 111. The dimensional parameters of the crests 111 of the sheet portion 110 can be compared with... Figures 5 to 7 The peak 111 in the example shown may be the same or different.

[0094] Continue reading Figure 10 In the example shown, a connecting plate segment 114 is also provided between at least two adjacent crests 111 between two adjacent columns of clamp sections 120, in order to avoid the generation of transverse vortices at the junction of the left crest 111 and the right crest 111, or to weaken the transverse vortices at that junction.

[0095] Continue reading Figure 10The width L4 of the connecting plate segment 114 is selected from any value from 0.8mm to 10mm, specifically any feasible value such as 0.8mm, 1mm, 1.5mm, 1.9mm, 2.3mm, 3mm, 3.8mm, 4mm, 4.56mm, 5mm, 5.5mm, 6mm, 8mm, 9mm, 9.2mm, 10mm, etc.

[0096] Continue reading Figure 10 The connecting plate segment 114 can be perpendicular to the axis of the pipe clamp part 120.

[0097] like Figure 11 As shown, in the example shown, with Figure 10 The example shown differs in that a concave-convex structure 1141 is provided on the connecting plate segment 114 to disrupt the boundary layer on the surface of the connecting plate segment 114 formed by the airflow. The height of the concave-convex structure 1141 protruding from the connecting plate segment 114 is selected from any value between 0.2 mm and 0.5 × H2.

[0098] like Figure 12 As shown, in the example shown, with Figure 10 The example shown is different, except that... Figure 10 The connecting plate segment 114 shown is configured as a V-shaped structure.

[0099] like Figure 13 As shown, the present invention also provides an air conditioner 002, which includes the heat exchanger 001 described in any of the preceding embodiments.

[0100] The air conditioner 002 of this utility model can be a split-type air conditioner or an integrated air conditioner.

[0101] Among them, split-type air conditioners, such as Figure 13 The illustrated unit includes an indoor air conditioning unit 300 and an outdoor air conditioning unit 400. The indoor air conditioning unit 300 can be a wall-mounted air conditioner, a floor-standing air conditioner, a ducted air conditioner, a ceiling-mounted air conditioner, etc. The heat exchanger 001 described in any of the preceding embodiments can be arranged in the indoor air conditioning unit 300 or in the outdoor air conditioning unit 400.

[0102] Among them, the integrated air conditioner can be a window unit.

[0103] Furthermore, in the air conditioner 002, the heat exchanger 001 can be any feasible configuration such as type I, type L, type U, type O, multi-fold type, etc.
