Description

Technical Field

[0001] This invention relates to the field of heat exchanger technology, specifically providing a heat exchange fin and a heat exchanger. Background Technology

[0002] Air conditioners have become a common household appliance, and heat exchangers are one of the most important components. Finned heat exchangers are favored by manufacturers due to their advantages such as affordability, small size, light weight, and good heat transfer performance. Finned heat exchangers consist of multiple heat exchange fins, including corrugated and slit fins. However, regardless of whether it's a corrugated or slit fin, current manufacturers only consider the fin strength in the lateral rolling direction or the direction perpendicular to the fin body during manufacturing. This leads to excessive strength in one direction but poor overall strength.

[0003] Accordingly, there is a need in the art for a new type of heat exchange fin and heat exchanger to solve the above-mentioned technical problems. Summary of the Invention

Furthermore, at least a portion of the second corrugated structure has a higher setting height along the protrusion direction of the reinforcing structure than the third inclined portion along the protrusion direction of the reinforcing structure.

[0012] In the preferred embodiment of the heat exchange fins described above, the air passage assembly further includes a sixth inclined portion, which is connected to the second protrusion and is arranged in a mirror image symmetrically with the third inclined portion along the second trough; and / or the air passage assembly further includes a seventh inclined portion, which is connected to the sixth inclined portion and forms an air passage gap between the seventh inclined portion and the sixth inclined portion.

[0013] In the preferred embodiment of the heat exchange fins described above, the number of air duct components is two, and the two sets of air duct components are arranged symmetrically along the circumferential axis of the pipe hole.

[0028] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the invention and are not intended to limit the scope of protection of the invention. Those skilled in the art can make adjustments as needed to adapt to specific applications. For example, the present invention does not impose any restrictions on the specific application of the heat exchanger formed by the heat exchange fins; it can be a wall-mounted air conditioner, a cabinet air conditioner, a ceiling-mounted air conditioner, a traditional air conditioner, or a fresh air air conditioner. Those skilled in the art can set the application according to actual usage requirements. Such changes in specific application do not deviate from the basic principles of the present invention and fall within the scope of protection of the present invention.

[0029] It should be noted that in the description of this invention, terms such as "upper," "lower," "left," and "right," indicating directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the structure must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first," "second," "third," "fourth," "fifth," "sixth," and "seventh" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the term "connected" should be interpreted broadly. For example, it can refer to a fixed connection or a detachable connection; it can refer to a direct connection or an indirect connection through an intermediate medium; it 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 invention according to the specific circumstances.

[0031] In view of the problem mentioned in the background art that the existing heat exchange fins have excessive strength in one direction but poor overall strength, the present invention provides a new heat exchange fin that aims to improve both the strength in the lateral rolling direction and the strength in the direction perpendicular to the fin body.

[0032] First refer to Figure 1 , Figure 1 This is a top view of the heat exchange fins of the present invention. Figure 1As shown, the heat exchange fin of the present invention includes a fin body 1, an air-passing assembly 2, and a reinforcing structure 3. The fin body 1 has a pipe hole 4 through which a heat exchange tube can pass. At least a portion of the fin body 1 protrudes along the axial direction of the pipe hole 4 to form the reinforcing structure 3, which surrounds the pipe hole 4. The air-passing assembly 2 is connected to the reinforcing structure 3, and at least a portion of the air-passing assembly 2 surrounds the reinforcing structure 3. The present invention, through the reinforcement structure 3, can enhance the strength of the heat exchange fin in both the lateral rolling direction and the direction perpendicular to the heat exchange fin body 1; that is, the present invention, through the reinforcement structure 3, can effectively enhance the overall strength of the heat exchange fin.

[0033] It should be noted that the present invention does not impose any restrictions on the specific structure of the fin body 1 and the air-passing assembly 2, as long as the air-passing assembly 2 can allow air to pass through so that the air can exchange heat with the heat exchange fins. Those skilled in the art can set it according to the actual situation. In addition, it should also be noted that the present invention does not impose any restrictions on the specific shape of the tube hole 4. In this preferred embodiment, the tube hole 4 is circular. Furthermore, the fin body 1 protrudes upward around the tube hole 4 along the direction of the reinforcing structure 3 to form a boss 5. The boss 5 can effectively enhance the strength of the fin body 1 near the tube hole 4.

[0034] See next Figures 1 to 5 ,in, Figure 2 This is a side view of the heat exchange fins of the present invention. Figure 3 This is a schematic diagram of the heat exchange fins of the present invention from another angle. Figure 4 yes Figure 1 Sectional view at point AA. Figure 5 yes Figure 1 A sectional view at point BB. (See image below.) Figures 1 to 5 As shown, the reinforcing structure 3 includes a first protrusion 31, a second protrusion 32, and a longitudinal reinforcing part 33. The first protrusion 31, the second protrusion 32, and the longitudinal reinforcing part 33 are all inclined and integrally formed. Figure 2 As shown, the highest point of the first protrusion 31 is connected to the highest point of the second protrusion 32, and the first protrusion 31 and the second protrusion 32 together form an arched structure; see reference. Figure 4 The cross-sectional structure of the arch-shaped structure formed by the first protrusion 31, the second protrusion 32, and the longitudinal reinforcement 33 is triangular in shape (see reference). Figure 4(The bolded portion in the middle), and the angle of angle A1 in the triangle is 67.3°. Based on the above structural configuration, the first protrusion 31 and the second protrusion 32 can effectively enhance the strength of the heat exchange fins in the lateral rolling direction. It should be noted that the present invention does not impose any restrictions on the specific shape of the quadrilateral, that is, it does not impose any restrictions on the specific arched shape of the first protrusion 31 and the second protrusion 32, as long as it can enhance the strength of the heat exchange fins in the lateral rolling direction, and those skilled in the art can set it according to the actual situation.

[0035] Furthermore, at least a portion of the vertical fin body 1 of the longitudinal reinforcing part 33 is provided, and the lowest point of the second protrusion 32 is connected to the highest point of the longitudinal reinforcing part 33; specifically, the lowest point of the second protrusion 32 and the highest point of the longitudinal reinforcing part 33 are connected by the vertical reinforcing plate of the longitudinal reinforcing part 33. Figure 5 As shown, the cross-sectional structure of the longitudinal reinforcement 33 is generally a right triangle (see reference). Figure 5 (The thickened part in the middle) The longitudinal reinforcement 33 can effectively enhance the strength of the heat exchange fins in the direction perpendicular to the fin body 1.

[0036] More preferably, there are two first protrusions 31 and two second protrusions 32, one longitudinal reinforcing part 33, and two second protrusions 32 are disposed on both sides of the longitudinal reinforcing part 33. The two sets of first protrusions 31 and second protrusions 32 are symmetrically arranged along the axis of symmetry of the longitudinal reinforcing part 33.

[0037] More preferably, the number of reinforcing structures 3 is two, and the two reinforcing structures 3 are symmetrically arranged along the circumferential axis of the tube hole; the arrangement of two reinforcing structures 3 can further enhance the overall strength of the heat exchange fins and make the strength of the heat exchange fins more uniform.

[0038] See Figure 1 and 2 ,like Figure 1 and 2 As shown, the remaining part of the fin body 1 forming the reinforcing structure 3 is groove-shaped. Four first protrusions 31 surround to form an approximately annular groove. A trapezoidal groove is formed between the longitudinal reinforcing part 33 and the two connected second protrusions 32. The annular groove and the trapezoidal groove are connected, and the trapezoidal groove and the annular groove are symmetrically arranged relative to the axis of symmetry of the tube hole 4 (i.e., Figure 1 (The left and right sides are symmetrical), and the shape of the trapezoidal groove is an isosceles trapezoid.

[0039] Those skilled in the art will understand that for fin bodies 1 of the same size, the larger the proportion of trapezoidal grooves and annular grooves, the smaller the proportion of the reinforcing structure formed by the fin body 1, and the lower the overall strength of the heat exchange fins. Those skilled in the art can determine the specific size of trapezoidal grooves and annular grooves according to the actual required strength, and the present invention does not impose any restrictions on this.

[0040] Continue reading Figures 1 to 5 In this preferred embodiment, the air-passing component 2 includes a first corrugated structure 21, which includes a first inclined portion 211 and a second inclined portion 212. The first inclined portion 211 is connected to the first protrusion 31. The two first inclined portions 211 are disposed between the two second inclined portions 212. The first corrugated structure 21 includes a first trough 213 and two peaks 214. The two first inclined portions 211 form the first trough 213, and adjacent first inclined portions 211 and second inclined portions 212 form peaks 214. The first trough 213 is located between the two peaks 214.

[0041] It should be noted that the present invention does not impose any limitations on the width, length, and tilt angle of the first inclined portion 211 and the second inclined portion 212, which can be set by those skilled in the art according to actual conditions. As a preferred embodiment, the two first inclined portions 211 are arranged in a mirror symmetrical manner along the first trough 213, and the two second inclined portions 212 are also arranged in a mirror symmetrical manner along the first trough 213, wherein the angle A2 between the first inclined portion 211 and the horizontal plane is 7.36°, and the angle A3 between the second inclined portion 212 and the horizontal plane is 170°, so as to ensure the airflow of the airflow component 2 and enhance the strength of the airflow component 2.

[0042] Preferably, the airflow assembly 2 further includes a third inclined portion 22, which is connected to the first protrusion 31. The two third inclined portions 22 are arranged in a mirror-symmetrical manner along the first trough 213, and the inclination height of the end of the third inclined portion 22 closer to the first corrugated structure 21 is higher than the inclination height of the end of the third inclined portion 22 away from the first corrugated structure 21. That is, an airflow gap is formed between the third inclined portion 22 and the second inclined portion 212 through the inclined arrangement, so that the air can exchange heat with the heat exchange fins. Preferably, the third inclined portion 22 and the second inclined portion 212 are arranged in parallel, that is, the angle A4 between the third inclined portion 22 and the horizontal direction is also 170°, so as to maximize the ventilation volume between the third inclined portion 22 and the second inclined portion 212.

[0043] Furthermore, the air-passing assembly 2 also includes a second corrugated structure 23, which includes a fourth inclined portion 231 and a fifth inclined portion 232. The fourth inclined portion 231 is connected to the first protrusion 31, and the fifth inclined portion 232 is connected to the second protrusion 32. Specifically, the connection between the fourth inclined portion 231 and the fifth inclined portion 232 and the connection between the first protrusion 31 and the second protrusion 32 are on the same straight line. In addition, the fourth inclined portion 231 and the fifth inclined portion 232 form a second trough 233, wherein the angle A5 between the fifth inclined portion 232 and the horizontal plane is 10°.

[0044] In a preferred embodiment, there are two second corrugated structures 23, which are symmetrically arranged along the first trough 213, and as shown in the figure. Figure 2 As shown, at least a portion of the second corrugated structure 23 is positioned at a height higher than the third inclined portion 22 along the direction of the reinforcing structure 3, so that an air gap is formed between the lowest point of the third inclined portion 22 and the highest point of the fourth inclined portion 231, thereby increasing the overall ventilation of the heat exchange fins.

[0045] More preferably, the airflow assembly 2 further includes a sixth inclined portion 24 and a seventh inclined portion 25. The sixth inclined portion 24 is connected to the second protrusion 32, and the sixth inclined portion 24 and the third inclined portion 22 are arranged in a mirror image symmetrically along the second trough 233. The seventh inclined portion 25 is connected to the sixth inclined portion 24 and the longitudinal reinforcing portion 33, and an airflow hole 26 is formed between the seventh inclined portion 25 and the sixth inclined portion 24, and an airflow gap is formed between the sixth inclined portion 24 and the fifth inclined portion 232, so as to further improve the overall airflow of the heat exchange fins, that is, to improve the heat exchange effect of the heat exchange fins. Preferably, the sixth inclined portion 24 is arranged in parallel with the fifth inclined portion 232, the angle A6 between the seventh inclined portion 25 and the horizontal plane is 172.6°, and the angle A7 between the sixth inclined portion 24 and the seventh inclined portion 25 is 17.37°; in addition, the lowest point of the inclination of the sixth inclined portion 24 is lower than the highest point of the inclination of the fifth inclined portion 232, and the highest point of the inclination of the seventh inclined portion 25 is lower than the highest point of the inclination of the sixth inclined portion 24.

[0046] It should be noted that in the above-mentioned set of air-passing components 2, the number of the first inclined portion 211, the second inclined portion 212, the third inclined portion 22, the fourth inclined portion 231, the fifth inclined portion 232, the sixth inclined portion 24, and the seventh inclined portion 25 are all two, and the two corresponding structures are arranged in a mirror symmetrical manner along the first trough 213. Those skilled in the art will understand that the sum of the angles between the first inclined portion 211, the second inclined portion 212, the third inclined portion 22, the fourth inclined portion 231, the fifth inclined portion 232, the sixth inclined portion 24, and the seventh inclined portion 25 and the horizontal plane and the angles between the other set of the first inclined portion 211, the second inclined portion 212, the third inclined portion 22, the fourth inclined portion 231, the fifth inclined portion 232, the sixth inclined portion 24, and the seventh inclined portion 25 and the horizontal plane is 180°. For example, if the angle A2 between the first inclined portion 211 and the horizontal plane is 7.36°, then the angle between the other first inclined portion 211 and the horizontal plane should be 172.64°.

[0047] Based on the specific structural configuration of the airflow assembly 2 described above, the first corrugated structure 21, the third inclined portion 22, and the second corrugated structure 23 are arranged in a stepped upward manner, while the second corrugated structure 23, the sixth inclined portion 24, and the seventh inclined portion 25 are arranged in a stepped downward manner. This creates a turbulent flow effect on the air passing through the heat exchange fins, further enhancing the heat exchange efficiency of the fins. It should be noted that, based on the above structural configuration, the present invention does not impose any restrictions on the specific values ​​of the included angles A1, A2, A3, A4, A5, A6, and A7, as long as the included angles A3, A4, and A6 are obtuse angles, and A1, A2, A5, and A7 are acute angles, so that the airflow assembly 2 presents a structure that first rises in a stepped manner from the middle outwards and then descends in a stepped manner. As an alternative, the air duct component 2 can also present a structure that descends in a stepped manner from the middle outwards and then rises in a stepped manner. Accordingly, the included angles A3, A4, and A6 are acute angles, and A1, A2, A5, and A7 are obtuse angles. Of course, this is not a limitation, and those skilled in the art can set it according to the actual situation.

[0048] Alternatively, the number of air duct components 2 is two sets, and the two sets of air duct components 2 are arranged symmetrically along the circumferential axis of symmetry of the pipe hole 4 (i.e., Figure 1 The heat exchange fins are arranged symmetrically (top and bottom) to double the airflow. Furthermore, in this preferred embodiment, the projections of the first corrugated structure 21, the third inclined portion 22, the second corrugated structure 23, the sixth inclined portion 24, and the seventh inclined portion 25 on the horizontal plane do not overlap, and the projections of adjacent structures are perfectly aligned. This arrangement ensures the airflow of the heat exchange fins while maximizing the turbulence effect on the airflow through the perfectly aligned projections of adjacent structures, thereby improving the heat exchange efficiency of the fins. Additionally, it minimizes the material usage and weight of the heat exchange fins.

[0049] Based on the above configuration, in this preferred embodiment, the heat exchange fins deform by 162.25 mm when subjected to a force perpendicular to the fin body 1; and deform by 90.49 mm when subjected to a force in the lateral rolling direction. That is, based on the above configuration, the heat exchange fins of the present invention can take into account both the strength in the direction perpendicular to the fin body 1 and the strength in the lateral rolling direction.

[0050] Furthermore, the present invention also claims a heat exchanger comprising the heat exchange fins described in the preferred embodiments above. Of course, those skilled in the art will understand that the specific arrangement of the multiple heat exchange fins in the heat exchanger is not limiting, and can be determined by those skilled in the art according to actual circumstances.

[0051] Furthermore, it should be noted that the present invention does not impose any restrictions on the specific usage of the heat exchange fins and heat exchanger; those skilled in the art can set their own methods according to the actual situation.

[0052] The technical solutions of the present invention have been described in conjunction with the optional embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of the present invention.
