[0002] In existing technologies, to avoid installation interference between the corners of the finned body and the inner wall of the air conditioner during heat exchanger installation, the length of the finned body is usually reduced. At the same time, the number of rows of heat exchange tubes along the width direction of the finned body is increased to ensure the heat exchange efficiency of the heat exchanger. However, increasing the number of rows of heat exchange tubes along the width direction of the finned body can easily lead to low utilization of heat exchange tubes, resulting in waste and high cost.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] The fins 10 of a heat exchanger 100 according to an embodiment of the present invention are described below with reference to the accompanying drawings.

[0048] like Figure 1 As shown, the fins 10 of the heat exchanger 100 according to an embodiment of the present invention include a fin body 1.

[0049] Specifically, as shown in the figure, the fin body 1 is rectangular, and the length direction of the fin body 1 (e.g., Figure 1 The first notch 11 and the second notch 12 are respectively located at two corners at the same end of the fin body 1 in the first direction shown. The first notch 11 and the second notch 12 are in the width direction of the fin body 1 (e.g., in the first direction shown). Figure 1 The first notch 11 and the second notch 12 are spaced apart in the second direction shown. The distance between them along the width direction of the fin body 1 is H1, and the width of the fin body 1 is H, and satisfies: 1 / 3≤H1 / H≤3 / 4.

[0050] Furthermore, the fin body 1 being rectangular means that the overall outline of the fin body 1 is basically rectangular, for example, it is basically rectangular without considering the first notch 11 and the second notch 12.

[0051] It is understandable that the fin body 1 has a through hole 15 for the heat exchange tube 20 to pass through. The heat exchange tube 20 is installed in the through hole 15. In order to avoid installation interference between the corner of the fin body 1 and the inner wall of the air conditioner 100 during the installation of the heat exchanger 100, the length of the fin body 1 is usually reduced. At the same time, the number of rows of heat exchange tubes 20 along the width direction of the fin body 1 in the heat exchanger 100 is increased to ensure the heat exchange efficiency of the heat exchanger 100. However, increasing the number of rows of heat exchange tubes 20 along the width direction of the fin body 1 in the heat exchanger 100 can easily lead to low utilization of the heat exchange tubes 20, resulting in waste and high cost.

[0052] Therefore, by setting the first notch 11 and the second notch 12, the area at the two corners at the same end of the fin body 1 along its length direction can be reduced, thereby reducing the installation interference between the two corners at the same end of the fin body 1 along its length direction and the air conditioner 1000. This ensures the length of the fin body 1, thus ensuring that there is a sufficient number of heat exchange tubes 20 along the length direction of the fin body 1 in the heat exchanger 100 to guarantee heat exchange efficiency. It also helps to reduce the number of rows of heat exchange tubes 20, simplifying the structure, improving the utilization rate of the heat exchange tubes 20, and reducing manufacturing costs. At the same time, it further reduces the material used in the fin body 1, reducing the production cost of the heat exchanger 100. Meanwhile, after setting the first notch 11 and the second notch 12 at the same end of the fin body 1 along its length direction, the width of the fin body 1 at the end with the first notch 11 and the second notch 12 is reduced. By placing the end of the fin body 1 with the smaller width at the bottom, the clearance width at the position of the water receiving tray 200 opposite to the fin body 1 can be reduced.

[0053] Furthermore, the distance between the first notch 11 and the second notch 12 along the width direction of the fin body 1 is H1, and the width of the fin body 1 is H, satisfying: 1 / 3 ≤ H1 / H ≤ 3 / 4. It is understandable that when the size of the first notch 11 and the second notch 12 located at the same end along the length direction of the fin body 1 is too large, it will affect other structures of the fin body 1 and the original function of the fin body 1 after setting the first notch 11 and the second notch 12. For example, it will significantly reduce the surface area of ​​the fin body 1, and at the same time, it will greatly reduce the number of through holes 15 on the fin body 1, thereby reducing the number of heat exchange tubes 20, which is not conducive to improving heat exchange efficiency. On the other hand, when the size of the first notch 11 and the second notch 12 is too small, there will still be installation interference between the corner of the fin body 1 and the inner wall of the air conditioner 1000, causing interference between the fin body 1 and the inner wall of the air conditioner 1000. When the relationship between H1 and H satisfies: 1 / 3≤H1 / H≤3 / 4, the distance between the first notch 11 and the second notch 12 located at the same end of the fin body 1 along the width direction of the fin body 1 is within a reasonable range. This will not affect the utilization rate of the heat exchange tube 20 on the fin body 1, and will also avoid interference between the fin body 1 and the inner wall of the air conditioner 1000.

[0054] According to the embodiment of the present invention, the fins 10 of the heat exchanger 100 have a first notch 11 and a second notch 12 respectively provided at two corners at the same end of the fin body 1 along the length direction. This reduces the area at the two corners at the same end of the fin body 1 along the length direction, thereby reducing installation interference between the two corners at the same end of the fin body 1 along the length direction and the air conditioner 1000. Furthermore, the distance between the first notch 11 and the second notch 12 along the width direction of the fin body 1 is H1, and the width of the fin body 1 is H, satisfying: 1 / 3 ≤ H1 / H ≤ 3 / 4. This ensures that the distance between the first notch 11 and the second notch 12 at the same end of the fin body 1 along the width direction of the fin body 1 is within a reasonable range. This avoids affecting the utilization rate of the heat exchange tubes 20 on the fin body 1 and also prevents interference between the fin body 1 and the inner wall of the air conditioner 1000.

[0055] In some embodiments of this utility model, as shown in the figure, the fin body 1 has through holes 15 for heat exchange tubes 20 to pass through. Multiple through holes 15 in the same row are spaced apart along the length direction of the fin body 1. The distance between the centers of two adjacent through holes 15 in the same row is P. A certain gap is provided between two adjacent through holes 15. There is a certain gap between the heat exchange tubes 20 passing through the through holes 15, thereby improving the heat exchange efficiency of the heat exchanger 100.

[0056] Along the length of the fin body 1, the length of the first notch 11 is L11, and satisfies: 1 / 3≤L11 / P≤4 / 3; thus, when the first notch 11 is set at the corner of the fin body 1, it is beneficial to make the first notch 11 avoid the position of the through hole 15 on the fin body 1, which is beneficial to ensure the number of through holes 15 on the fin body 1, thereby ensuring the heat exchange performance of the heat exchanger 100.

[0057] Along the length of the fin body 1, the length of the second notch 12 is L12, and satisfies: 1 / 3 ≤ L12 / P ≤ 4 / 3. Thus, when the second notch 12 is set at the corner of the fin body 1, it is beneficial to ensure that the second notch 12 avoids the position of the through hole 15 on the fin body 1, which helps to ensure the number of through holes 15 on the fin body 1, thereby ensuring the heat exchange performance of the heat exchanger 100.

[0058] In some embodiments of this utility model, along the length direction of the fin body 1, the length of the first notch 11 is L11, and the length of the second notch 12 is L12, satisfying: L11=L12. It can be understood that, as shown in the figure, the fin bodies 1 are tightly arranged on the raw material before cutting. Multiple rows of fin bodies 1 are arranged on the raw material along the length direction of the fin body 1 and need to be cut. To reduce the cutting loss of the raw material and improve the utilization rate of the raw material, the edges at both ends of the width direction of two adjacent rows of fin bodies 1, excluding the notches, are arranged to overlap on the raw material. When L11=L12, the overlapping edges at both ends of the width direction of the fin body 1 have the same length. In this way, through one cutting, one edge of two fin bodies 1 can be cut out separately, improving the production efficiency of the fin bodies 1.

[0059] In some embodiments of this utility model, the two corners at the other end of the fin body 1 along the length direction have a third notch 13 and a fourth notch 14. The third notch 13 and the fourth notch 14 are spaced apart along the width direction of the fin body 1. The spacing between the third notch 13 and the fourth notch 14 along the width direction of the fin body 1 is H2, and satisfies: 1 / 3≤H2 / H≤3 / 4.

[0060] By setting the third notch 13 and the fourth notch 14, the area at the two corners at the other end of the fin body 1 along its length direction can be reduced, thereby reducing the installation interference between the two corners at the other end of the fin body 1 along its length direction and the air conditioner 1000. This ensures the length of the fin body 1, thus ensuring that there is a sufficient number of heat exchange tubes 20 along the length direction of the fin body 1 in the heat exchanger 100 to guarantee heat exchange efficiency. It also helps to reduce the number of rows of heat exchange tubes 20, simplifying the structure, improving the utilization rate of the heat exchange tubes 20, and reducing manufacturing costs. At the same time, it further reduces the material used in the fin body 1, reducing the production cost of the heat exchanger 100. Meanwhile, after setting the third notch 13 and the fourth notch 14 at the other end of the fin body 1 along its length direction, the width of the fin body 1 at the end with the third notch 13 and the fourth notch 14 is reduced. By placing the end of the fin body 1 with the smaller width at the bottom, the clearance width at the position of the water receiving tray 200 opposite to the fin body 1 can be reduced, and the design flexibility of choosing the position to cooperate with the water receiving tray 200 can be increased according to requirements.

[0061] Furthermore, the distance between the third notch 13 and the fourth notch 14 along the width direction of the fin body 1 is H2, and satisfies: 1 / 3 ≤ H2 / H ≤ 3 / 4. It is understandable that when the dimensions of the third notch 13 and the fourth notch 14 located at the other end of the length direction of the fin body 1 are too large, it will affect other structures and the original functions of the fin body 1. For example, it will significantly reduce the surface area of ​​the fin body 1, and also greatly reduce the number of through holes 15 on the fin body 1, thereby reducing the number of heat exchange tubes 20, which is not conducive to improving heat exchange efficiency. Conversely, when the dimensions of the third notch 13 and the fourth notch 14 are too small, installation interference still exists between the corner of the fin body 1 and the inner wall of the air conditioner 1000, causing interference between the fin body 1 and the inner wall of the air conditioner 1000. When the relationship between H2 and H satisfies: 1 / 3≤H2 / H≤3 / 4, the spacing between the third notch 13 and the fourth notch 14 at the other end of the length direction of the fin body 1 along the width direction of the fin body 1 is within a reasonable range. This will not affect the utilization rate of the heat exchange tube 20 on the fin body 1, and will also avoid interference between the fin body 1 and the inner wall of the air conditioner 1000.

[0062] Furthermore, H1 = H2. It should be noted that during the production of fin body 1, multiple rows of fin bodies 1 are arranged along the length direction of the fin body 1 on the raw material and need to be cut. In order to improve the utilization rate of raw materials, the edges at both ends of the length direction of two adjacent rows of fin bodies 1 on the raw material, excluding the first notch 11, the second notch 12, the third notch 13 and the fourth notch 14, will overlap with each other. When H1 = H2, the connecting edges at both ends of the length direction of two adjacent rows of fin bodies 1 have the same size and overlap with each other. In this way, one edge at both ends of the length direction of two fin bodies 1 can be cut out in one cut, which improves the production efficiency of fin body 1.

[0063] In some embodiments of this utility model, the fin body 1 has through holes 15 for heat exchange tubes 20 to pass through. Multiple through holes 15 in the same row are spaced apart along the length direction of the fin body 1. The distance between the centers of two adjacent through holes 15 in the same row is P. A certain gap is provided between two adjacent through holes 15. There is a certain gap between the heat exchange tubes 20 passing through the through holes 15, thereby improving the heat exchange efficiency of the heat exchanger 100.

[0064] Along the length of the fin body 1, the length of the third notch 13 is L21, and satisfies: 1 / 3≤L21 / P≤4 / 3; thus, when the third notch 13 is set at the corner of the fin body 1, it is beneficial to make the third notch 13 avoid the position of the through hole 15 on the fin body 1, which is beneficial to ensure the number of through holes 15 on the fin body 1, thereby ensuring the heat exchange performance of the heat exchanger 100.

[0065] The length of the fourth notch 14 is L22, along the length direction of the fin body 1, and satisfies: 1 / 5≤L22 / P≤1; thus, when the fourth notch 14 is set at the corner of the fin body 1, it is beneficial to make the fourth notch 14 avoid the position of the through hole 15 on the fin body 1, which is beneficial to ensure the number of through holes 15 on the fin body 1, thereby ensuring the heat exchange performance of the heat exchanger 100.

[0066] Furthermore, along the length direction of the fin body 1, the length of the third notch 13 is L21, and the length of the fourth notch 14 is L22, where L21 = L22. It can be understood that, as shown in the figure, the fin bodies 1 are tightly arranged on the raw material before cutting. Multiple rows of fin bodies 1 are arranged along the length direction of the fin body 1 on the raw material and need to be cut. To reduce cutting waste and improve the utilization rate of the raw material, the edges at both ends of the width direction of two adjacent rows of fin bodies 1, excluding the notches, are arranged to overlap on the raw material. When L21 = L22, the overlapping edges at both ends of the width direction of the fin body 1 have the same length. In this way, one edge of two fin bodies 1 can be cut out in one cut, improving the production efficiency of the fin bodies 1.

[0067] In some embodiments of this utility model, the first notch 11, the second notch 12, the third notch 13, and the fourth notch 14 may have the same or different shapes. It is understood that the first notch 11, the second notch 12, the third notch 13, and the fourth notch 14 may all have the same shape, or three of the first notch 11, the second notch 12, the third notch 13, and the fourth notch 14 may have the same shape, or two of the first notch 11, the second notch 12, the third notch 13, and the fourth notch 14 may have the same shape, or each of the first notch 11, the second notch 12, the third notch 13, and the fourth notch 14 may have a different shape. Setting the first notch 11, the second notch 12, the third notch 13, and the fourth notch 14 on the fin body 1 to have the same shape simplifies the overall structural shape of the fin body 1 and reduces the manufacturing difficulty of the fin body 1. Setting the first notch 11, the second notch 12, the third notch 13, and the fourth notch 14 on the fin body 1 to have different shapes helps to distinguish the orientation of the fin 10 and prevents errors during installation. The shapes of the first notch 11, the second notch 12, the third notch 13, and the fourth notch 14 can be selected according to design requirements to meet different application scenarios.

[0068] The number of through holes 15 in a row of through holes 15 closest to one edge in the width direction of the fin body 1 may be the same as or different from the number of through holes 15 in a row of through holes 15 closest to the other edge in the width direction of the fin body 1. It is understood that the number of through holes 15 in a row of through holes 15 closest to one edge in the width direction of the fin body 1 may be the same as or different from the number of through holes 15 in a row of through holes 15 closest to one edge in the width direction of the fin body 1.

[0069] The number of through holes 15 in the row of through holes 15 closest to one side edge in the width direction of the fin body 1 is the same as the number of through holes 15 in the row of through holes 15 closest to the other side edge in the width direction of the fin body 1, which simplifies the overall structural shape of the fin body 1 and makes it easier to process.

[0070] The number of through holes 15 in the row of through holes 15 closest to one edge in the width direction of the fin body 1 is different from the number of through holes 15 in the row of through holes 15 closest to the other edge in the width direction of the fin body 1. This helps to reduce the impact of setting the first notch 11, the second notch 12, the third notch 13 and the fourth notch 14 on the number of through holes 15 on the fin body 1, thereby ensuring the heat exchange effect of the heat exchanger 100.

[0071] In some embodiments of this utility model, the four corners of the fin body 1 are respectively provided with a first notch 11, a second notch 12, a third notch 13 and a fourth notch 14. The first notch 11, the second notch 12, the third notch 13 and the fourth notch 14 are symmetrical along the center line of the length direction of the fin body 1, which helps to simplify the overall structural shape of the fin body 1 and reduce the manufacturing and processing difficulty of the fin body 1.

[0072] In some embodiments of this utility model, the fin body 1 has a first notch 11 and a third notch 13 or a second notch 12 and a fourth notch 14 at two corners at the same end of the fin body 1 along the length direction. The first notch 11 and the third notch 13 have the same shape, or the second notch 12 and the fourth notch 14 have the same shape. The number of through holes 15 in a row of through holes 15 closest to one side edge along the width direction of the fin body 1 is the same as the number of through holes 15 in a row of through holes 15 closest to the other side edge along the width direction of the fin body 1. Setting the first notch 11 and the third notch 13 or the second notch 12 and the fourth notch 14 on the fin body 1 to have the same shape helps to simplify the overall structural shape of the fin body 1 and reduce the manufacturing difficulty of the fin body 1. At the same time, keeping the number of through holes 15 in the row of through holes 15 closest to one side edge in the width direction of the fin body 1 the same as the number of through holes 15 in the row of through holes 15 closest to the other side edge in the width direction of the fin body 1 makes the structure of the fin body 1 symmetrical along the center line of the length direction of the fin body 1, further simplifying the overall structural shape of the fin body 1 and making it easier to process.

[0073] In some embodiments of this utility model, the fin body 1 has a first notch 11 and a second notch 12 or a third notch 13 and a fourth notch 14 at two corners at the same end in the width direction of the fin body 1. The first notch 11 and the second notch 12 have the same shape, or the third notch 13 and the fourth notch 14 have the same shape. The number of through holes 15 in a row of through holes 15 closest to one side edge in the width direction of the fin body 1 is different from the number of through holes 15 in a row of through holes 15 closest to the other side edge in the width direction of the fin body 1. It is understandable that, since the first notch 11 and the second notch 12 or the third notch 13 and the fourth notch 14 are provided at the corner of the fin body 1, the number of through holes 15 in a row on one side edge of the fin body 1 with the first notch 11 and the second notch 12 or the third notch 13 and the fourth notch 14 in the width direction is reduced, while the number of through holes 15 in a row on the other side edge closest to the width direction of the fin body 1 remains unchanged. This helps to reduce the impact of setting the notch on the number of through holes 15 on the fin body 1, thereby ensuring the heat exchange effect of the heat exchanger 100.

[0074] In some other embodiments of this utility model, the fin body 1 has a first notch 11 and a third notch 13 or a second notch 12 and a fourth notch 14 at two corners at the same end of the fin body 1 along the length direction. The first notch 11 and the third notch 13 have different shapes, or the second notch 12 and the fourth notch 14 have different shapes. The number of through holes 15 in a row of through holes 15 closest to one side edge along the width direction of the fin body 1 is different from the number of through holes 15 in a row of through holes 15 closest to the other side edge along the width direction of the fin body 1. It is understandable that, due to the setting of the first notch 11 and the third notch 13 or the second notch 12 and the fourth notch 14, the number of through holes 15 in a row on one side edge of the fin body 1 with the first notch 11 and the third notch 13 or the second notch 12 and the fourth notch 14 in the width direction is reduced, while the number of through holes 15 in a row on the other side edge of the fin body 1 that is closest to the width direction remains unchanged. This helps to reduce the impact of setting the notch on the number of through holes 15 on the fin body 1, thereby ensuring the heat exchange effect of the heat exchanger 100.

[0075] In some embodiments of this utility model, the fin body 1 has a first notch 11 and a fourth notch 14 or a second notch 12 and a third notch 13 at two corners located diagonally on the fin body 1. The first notch 11 and the fourth notch 14 or the second notch 12 and the third notch 13 have the same shape. The number of through holes 15 in a row of through holes 15 closest to one side edge in the width direction of the fin body 1 is the same as the number of through holes 15 in a row of through holes 15 closest to the other side edge in the width direction of the fin body 1. Setting the first notch 11 and the fourth notch 14 or the second notch 12 and the third notch 13 to have the same shape helps to simplify the overall structural shape of the fin body 1 and reduce the manufacturing difficulty of the fin body 1. At the same time, keeping the number of through holes 15 in the row of through holes 15 closest to one side edge in the width direction of the fin body 1 the same as the number of through holes 15 in the row of through holes 15 closest to the other side edge in the width direction of the fin body 1 ensures that the heat exchange tubes 20 are evenly distributed on the fin body 1, which helps to ensure the heat exchange effect of the heat exchanger 100.

[0076] In some other embodiments of this utility model, in order to avoid the first notch 11, the second notch 12, the third notch 13 and the fourth notch 14 affecting the overall heat exchange area of ​​the fin body 1 and the number of heat exchange tubes 20 on the fin body 1, and to ensure the heat exchange performance of the heat exchanger 100, the first notch 11 and the fourth notch 14 or the second notch 12 and the third notch 13 at the two corners located on the diagonal position of the fin body 1 will have different shapes. As a result, the number of through holes 15 in the row of through holes 15 closest to one side edge in the width direction of the fin body 1 will be different from the number of through holes 15 in the row of through holes 15 closest to the other side edge in the width direction of the fin body 1.

[0077] In some embodiments of this utility model, the four corners of the fin body 1 are respectively provided with a first notch 11, a second notch 12, a third notch 13 and a fourth notch 14, and the shapes of the first notch 11, the second notch 12, the third notch 13 and the fourth notch 14 are all the same. The number of through holes 15 in the row of through holes 15 closest to one side edge in the width direction of the fin body 1 is the same as the number of through holes 15 in the row of through holes 15 closest to the other side edge in the width direction of the fin body 1. This is beneficial to simplify the overall structural shape of the fin body 1 and reduce the manufacturing and processing difficulty of the fin body 1.

[0078] In some other embodiments of this utility model, in order to avoid affecting the overall heat exchange area of ​​the fin body 1 and the number of heat exchange tubes 20 on the fin body 1 after setting the first notch 11, the second notch 12, the third notch 13 and the fourth notch 14, and to ensure the heat exchange performance of the heat exchanger 100, the shapes of the notches at the four corners of the fin body 1 are different, and the number of through holes 15 in the row of through holes 15 closest to one side edge in the width direction of the fin body 1 is the same as the number of through holes 15 in the row of through holes 15 closest to the other side edge in the width direction of the fin body 1.

[0079] In some other embodiments of the present invention, the outer contour of at least one of the first notch 11, the second notch 12, the third notch 13 and the fourth notch 14 includes a first straight segment 111, a first inclined segment 112 and a second straight segment 113 connected in sequence. The first straight segment 111 and the first inclined segment 112 are arranged in sequence along the length direction of the fin body 1. The first straight segment 111 extends along the length direction of the fin body 1. The end of the first straight segment 111 away from the first inclined segment 112 is connected to the edge of the fin body 1 in the width direction. The end of the first inclined segment 112 away from the first straight segment 111 extends obliquely toward one side of the fin body 1 in the width direction. The second straight segment 113 extends along the width direction of the fin body 1. The end of the second straight segment 113 away from the first inclined segment 112 is connected to the edge of the fin body 1 in the length direction.

[0080] By rationally arranging the outer contours of at least one of the first notch 11, the second notch 12, the third notch 13, and the fourth notch 14 of the fin body 1, it is beneficial to match the shapes of the first notch 11, the second notch 12, the third notch 13, and the fourth notch 14 with the installation space of the air conditioner 1000. At the same time, while ensuring heat exchange performance, the material used in the fin body 1 is further reduced and the number of heat exchange tubes 20 is guaranteed, thereby reducing production costs.

[0081] In other embodiments of this utility model, the outer contour of at least one of the first notch 11, the second notch 12, the third notch 13, and the fourth notch 14 includes a third straight segment 114, a fourth straight segment 115, a first arc-shaped segment 116, a second inclined segment 117, a fifth straight segment 118, and a sixth straight segment 119 connected in sequence. The third straight segment 114, the second inclined segment 117, and the fifth straight segment 118 are arranged sequentially along the length direction of the fin body 1. The third straight segment 114 and the fifth straight segment 118 are both along the fin body. The body 1 extends along its length direction. The fourth straight segment 115 and the sixth straight segment 119 both extend along the width direction of the fin body 1. The end of the third straight segment 114 away from the fourth straight segment 115 is connected to the edge of the fin body 1 in the width direction. The end of the second inclined segment 117 away from the first arc segment 116 extends inclined towards one side of the fin body 1 in the width direction. The first arc segment 116 bends towards the inside of the fin body 1. The end of the sixth straight segment 119 away from the fifth straight segment 118 is connected to the edge of the fin body 1 in the length direction.

[0082] By rationally arranging the outer contours of at least one of the first notch 11, the second notch 12, the third notch 13, and the fourth notch 14 of the fin body 1, it is beneficial to match the shapes of the first notch 11, the second notch 12, the third notch 13, and the fourth notch 14 with the installation space of the air conditioner 1000. At the same time, while ensuring heat exchange performance, the material used in the fin body 1 is further reduced and the number of heat exchange tubes 20 is guaranteed, thereby reducing production costs.

[0083] In some other embodiments of the present invention, the fin body 1 has multiple rows of through holes 15 spaced apart along the width direction of the fin body 1 for the heat exchange tube 20 to pass through. Each row of through holes 15 includes multiple through holes 15 spaced apart along the length direction of the fin body 1. The number of through holes 15 in at least one row of through holes 15 located in the middle of the fin body 1 is N, and the number of through holes 15 in one row of through holes 15 near the edge in the width direction of the fin 10 is N or N-1.

[0084] Understandably, in the existing heat exchanger 100, due to the influence of positional relationships, the heat exchange tubes 20 near the corner of the fin body 1 do not have sufficient contact with the flowing air, resulting in low heat exchange efficiency and a small increase in the heat exchange performance of the heat exchanger 100. By providing a first notch 11, a second notch 12, a third notch 13, or a fourth notch 14 on the fin body 1, the flow velocity distribution between the fin body 1 and the heat exchange tubes 20 can be made more uniform, improving the heat exchange efficiency between them. Although this partially results in the removal of the through holes 15 near the corner of the fin body 1, leading to a reduction in the number of heat exchange tubes 20, the overall heat exchange performance of the heat exchanger 100 is improved because the heat exchange efficiency of all heat exchange tubes 20 is enhanced. Furthermore, when the number of through holes 15 in at least one row of through holes 15 in the middle of the fin body 1 is N, and the number of through holes 15 in one row of through holes 15 near the edge of the fin body 1 in the width direction is N or N-1, the arrangement of the number of through holes 15 on the fin body 1 is more reasonable. This not only improves the heat exchange efficiency of the heat exchanger 100 and ensures that the overall heat exchange performance of the heat exchanger 100 is higher than that of the existing heat exchanger 100, but also reduces the number of heat exchange tubes 20 used and reduces the production cost of the heat exchanger 100.

[0085] In some other embodiments of this utility model, the number of through holes 15 in each row is 6-14. It is understood that the number of through holes 15 in each row can be 6, 7, 8, 9, 10, 11, 12, 13, or 14. The number of through holes 15 in each row can be selected according to heat exchange requirements to meet different design needs.

[0086] In some other embodiments of this utility model, the number of through holes 15 on the fin body 1 is even. The heat exchange tube 20 includes a straight tube section and a connecting pipe connected to both ends of the straight tube section. The connecting pipe is used to connect two adjacent heat exchange tubes 20 or the inlet and outlet pipes of the heat exchanger 100. The connecting pipe can be a U-shaped tube or a half U-shaped tube. The number of through holes 15 on the fin body 1 is even, which facilitates the use of U-shaped tubes to connect two adjacent heat exchange tubes 20 and facilitates the arrangement of the heat exchange tubes 20.

[0087] In some other embodiments of this utility model, the fin body 1 has three rows of through holes 15, and the number of the three rows of through holes 15 is even. Each row of heat exchange tubes 20 can be connected to two adjacent heat exchange tubes 20 by a U-shaped tube, so as to avoid U-shaped tubes from being connected across rows.

[0088] The number of through holes 15 in the row of through holes 15 located in the middle of the fin body 1 is even, while the number of through holes 15 in the two rows of through holes 15 near the two edges in the width direction of the fin 10 is odd. The two rows of heat exchange tubes 20 near the two edges in the width direction of the fin 10 are respectively connected to the inlet and outlet pipes of the heat exchanger 100. Except for the heat exchange tubes 20 connected to the inlet and outlet pipes of the heat exchanger 100, each row of heat exchange tubes 20 can be connected to two adjacent heat exchange tubes 20 with U-shaped tubes, and U-shaped tubes should be connected across rows as much as possible.

[0089] In some other embodiments of this utility model, the fin body 1 has three rows of through holes 15. The number of through holes 15 in one row located on one side of the width direction of the fin body 1 is even, and the number of through holes 15 in the other two rows is odd. This can meet different heat exchange requirements. The heat exchange tubes 20 in the other two rows are respectively connected to the inlet and outlet pipes of the heat exchanger 100. Except for the heat exchange tubes 20 connected to the inlet and outlet pipes of the heat exchanger 100, each row of heat exchange tubes 20 can be connected to two adjacent heat exchange tubes 20 with U-shaped tubes, avoiding U-shaped tubes from being connected across rows as much as possible.

[0090] In some other embodiments of this utility model, the fin body 1 has multiple rows of through holes 15 spaced apart along the width direction of the fin body 1 for the heat exchange tubes 20 to pass through. The edges of the fin body 1 along the length direction corresponding to the ends of at least one row of through holes 15 in the middle of the fin body 1 are not notched. This arrangement of the first notch 11, second notch 12, third notch 13, and fourth notch 14 causes minimal alteration to the overall shape of the fin body 1, reducing the impact of the first notch 11, second notch 12, third notch 13, and fourth notch 14 on the original structure and function of the fin 10. It avoids significantly reducing the overall heat exchange area of ​​the fin 10 after the first notch 11, second notch 12, third notch 13, and fourth notch 14 are set. Simultaneously, the absence of notches on the edges along the length direction of the fin body 1 corresponding to the ends of at least one row of through holes 15 in the middle of the fin body 1 ensures the number of through holes 15 in the middle of the fin body 1, thereby ensuring the number of heat exchange tubes 20 installed on the fin 10, which is beneficial for improving the heat exchange performance of the heat exchanger 100.

[0091] The heat exchanger 100 according to the present invention includes fins 10 and heat exchange tubes 20 as described in the above embodiments.

[0092] Specifically, the fins 10 are a plurality of spaced apart in the thickness direction of the fins 10, and the heat exchange tubes 20 are inserted through each fin 10. It can be understood that the heat exchange tubes 20 are devices for heat exchange of the refrigerant. The fins 10 have through holes 15, so that the heat exchange tubes 20 can be inserted through the fins 10. The fins 10 are used to increase the heat exchange area between the heat exchange tubes 20 and the airflow.

[0093] According to the heat exchanger 100 of this utility model embodiment, by providing a first notch 11 and a second notch 12 at two corners at the same end of the fin body 1 along its length, the area at the two corners at the same end of the fin body 1 along its length can be reduced, thereby reducing installation interference between the two corners at the same end of the fin body 1 along its length and the air conditioner 1000. Furthermore, the distance between the first notch 11 and the second notch 12 along the width direction of the fin body 1 is H1, and the width of the fin body 1 is H, satisfying: 1 / 3 ≤ H1 / H ≤ 3 / 4. This ensures that the distance between the first notch 11 and the second notch 12 at the same end of the fin body 1 along the width direction of the fin body 1 is within a reasonable range. This avoids affecting the utilization rate of the heat exchange tubes 20 on the fin body 1 and also prevents interference between the fin body 1 and the inner wall of the air conditioner 1000.

[0094] According to an embodiment of the present invention, an air conditioner 1000 includes a water receiving pan 200 and a heat exchanger 100. The heat exchanger 100 is disposed on the water receiving pan 200. The length direction of the heat exchanger 100 has an angle with both the vertical direction and the horizontal direction. The heat exchanger 100 is inclinedly disposed inside the air conditioner 1000. The length of the heat exchanger 100 can be increased within the housing 400 of the air conditioner 100 of the same size, thereby improving the heat exchange effect of the heat exchanger 100.

[0095] In the direction from front to back, the inner bottom wall of the water receiving tray 200 is inclined downward, which makes it easier for the condensate in the water receiving tray 200 to be concentrated in the lower part, thus facilitating the drainage of the water receiving tray 200.

[0096] Specifically, the air conditioner 1000 also includes a fan wheel 300, which is disposed within a housing 400. A heat exchanger 100 is also disposed within the housing 400, located on the air outlet side of the fan wheel 300. The housing 400 has an air inlet and an air outlet 401. Driven by the fan wheel 300, airflow from outside the air conditioner 1000 enters the housing 400 through the air inlet. The airflow inside the housing 400 flows through the heat exchanger 100 and exchanges heat with it. The airflow after heat exchange is exhausted is then blown out through the air outlet 401. The heat exchanger 100 is located on the air outlet side of the fan wheel 300 along the airflow direction, facilitating heat exchange between the air entering the air conditioner 1000 and the refrigerant within the heat exchanger 100.

[0097] Furthermore, an air intake grille is provided at the air inlet. On the one hand, the air intake grille can prevent hands or other foreign objects from entering the air conditioner 1000, protecting the user's safety and ensuring the normal operation of the air conditioner 1000. On the other hand, the air intake grille can prevent insects, rodents, etc. from entering the casing 400 of the air conditioner 1000 and causing damage to the air conditioner 1000, ensuring the normal operation of the air conditioner 1000 and ensuring the aesthetic appearance of the air conditioner 1000.

[0098] Optionally, the air intake grille is detachably connected to the housing 400. The air intake grille ensures the aesthetic appearance of the housing 400. After the air intake grille is removed, it is convenient to repair and replace the components inside the air conditioner 1000. At the same time, it is convenient to clean the air intake grille and avoid dust accumulation caused by prolonged use.

[0099] According to the embodiment of the present invention, the air conditioner 1000, by providing a first notch 11 and a second notch 12 at two corners at the same end of the fin body 1 along its length, can reduce the area at the two corners at the same end of the fin body 1 along its length, thereby reducing installation interference between the two corners at the same end of the fin body 1 along its length and the air conditioner 1000. Furthermore, the distance between the first notch 11 and the second notch 12 along the width direction of the fin body 1 is H1, and the width of the fin body 1 is H, satisfying: 1 / 3 ≤ H1 / H ≤ 3 / 4. This ensures that the distance between the first notch 11 and the second notch 12 at the same end of the fin body 1 along the width direction of the fin body 1 is within a reasonable range. This avoids affecting the utilization rate of the heat exchange tube 20 on the fin body 1 and also prevents interference between the fin body 1 and the inner wall of the air conditioner 1000.

[0100] The fins 10 of the heat exchanger 100, other configurations of the heat exchanger 100 and the air conditioner 1000 according to the embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
