For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0053] The heat exchanger assembly 10 according to the embodiments of the utility model is described below with reference to the drawings.

[0054] As shown in Figure 1 The heat exchanger assembly 10 according to the embodiments of the utility model includes a first heat exchanger 1 and a second heat exchanger 2.

[0055] Specifically, as shown in Figure 1 And Figure 8 The heat exchanger assembly 10 can be used in an air conditioner 100, for example, the air conditioner 100 is used indoors, and the heat exchanger assembly 10 absorbs and transfers the heat in the indoor air to the outdoor through the circulating refrigerant (such as freon, etc.), or transfers the heat from the outdoor to the indoor, so as to realize the adjustment of indoor temperature, which is the key equipment for realizing heat transfer in the air conditioner 100. In the cooling mode, the heat exchanger assembly 10 evaporates the refrigerant at low pressure, absorbs the heat of indoor air, and makes the indoor temperature drop; in the heating mode, the refrigerant is condensed at high temperature and high pressure through the condenser, and the heat is transferred to the indoor air, so that the indoor temperature rises.

[0056] Further, as shown in Figure 1As shown, the first heat exchanger 1 has a plurality of spaced-apart first fins 11 and first heat exchange tubes 12 passing through the plurality of first fins 11, with the plurality of first heat exchange tubes 12 penetrating the first fins 11; the second heat exchanger 2 has a plurality of spaced-apart second fins 21 and second heat exchange tubes 22 passing through the plurality of second fins 21. It can be understood that the first heat exchange tubes 12 and the second heat exchange tubes 22 are devices for heat exchange of the refrigerant, and the first fins 11 and the second fins 21 are used to increase the heat exchange area between the first heat exchange tubes 12 and the second heat exchange tubes 22 and the airflow.

[0057] Furthermore, such as Figure 1 As shown, the length direction of the plurality of second fins 21 (e.g.) Figure 1 One end of the second direction shown and the length direction of the plurality of first fins 11 (as shown in the second direction) and the length direction of the first fins 11 (as shown in the second direction) Figure 1 The ends of the heat exchangers (in the first direction shown) are spliced ​​or connected to form a heat exchanger assembly 10 with a larger heat exchange area, thereby improving the heat exchange performance of the heat exchanger assembly 10.

[0058] like Figure 1 As shown, the angle between the length direction of the first fin 11 and the length direction of the second fin 21 is A, and satisfies 74°≤A≤88°. It can be understood that the angle between the length direction of the first fin 11 and the length direction of the second fin 21 can be 74°, 75°, 76°, 77°, 78°, 79°, 80°, 81°, 82°, 83°, 84°, 85°, 86°, 87°, or 88°. The angle between the length direction of the first fin 11 and the length direction of the second fin 21 is not less than 74°, which ensures that there is a certain angle between the first heat exchanger 1 and the second heat exchanger 2, avoiding a small heat exchange area between the first heat exchanger 1 and the second heat exchanger 2, and avoiding a large overlap area between the first heat exchanger 1 and the second heat exchanger 2, so as to avoid affecting the heat exchange effect of the heat exchanger assembly 10; the angle between the length direction of the first fin 11 and the length direction of the second fin 21 is not greater than 88°, so that the heat exchanger assembly 10 can avoid the internal structure of the air conditioner 100, and avoid interference between the heat exchanger assembly 10 and the inner wall of the air conditioner 100.

[0059] According to the heat exchanger assembly 10 of this utility model embodiment, by limiting the included angle between the length direction of the first fins 11 spaced apart on the first heat exchanger 1 and the length direction of the second fins 21 spaced apart on the second heat exchanger 2 to A and satisfying 74°≤A≤88°, it can be ensured that there is a certain included angle between the first heat exchanger 1 and the second heat exchanger 2, so as to avoid affecting the heat exchange effect of the heat exchanger assembly 10; at the same time, it allows the heat exchanger assembly 10 to avoid the internal structure of the air conditioner 100, so as to avoid interference between the heat exchanger assembly 10 and the inner wall of the air conditioner 100.

[0060] In some embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 6 As shown, the first fin 11 includes a first fin body 111, and the second fin 21 includes a second fin body 211. Both the first fin body 111 and the second fin body 211 are rectangular. At two corners on the same end along the length direction of the first fin body 111, there are respectively a first notch 1111 and a second notch 1112. The first notch 1111 and the second notch 1112 are located in the width direction of the first fin body 111 (e.g., along the width direction of the first fin body 111). Figure 1 The first notch 1111 and the second notch 1112 are spaced apart along the width direction of the first fin body 111 by a distance of H1. The width of the first fin body 111 is H, and satisfies: 1 / 3≤H1 / H≤3 / 4.

[0061] Specifically, the first fin body 111 being rectangular means that the overall outline of the first fin body 111 is basically rectangular, for example, it is basically rectangular without considering the first notch 1111 and the second notch 1112.

[0062] The first fin body 111 has a first through hole 1113 for the first heat exchange tube 12 to pass through. The first heat exchange tube 12 is inserted into the first through hole 1113. To avoid installation interference between the corner of the first fin body 111 and the inner wall of the air conditioner 100 during the installation of the first heat exchanger 1, the length of the first fin body 111 is usually reduced. At the same time, the number of rows of the first heat exchange tubes 12 along the width direction of the first fin body 111 in the first heat exchanger 1 is increased to ensure the heat exchange efficiency of the first heat exchanger 1. However, increasing the number of rows of the first heat exchange tubes 12 along the width direction of the first fin body 111 in the first heat exchanger 1 can easily lead to low utilization of the first heat exchange tubes 12, resulting in waste and high cost.

[0063] Therefore, by arranging the first notch 1111 and the second notch 1112, the area of the two corners at the same end of the length direction of the first fin body 111 can be reduced, thereby reducing the installation interference between the two corners at the same end of the length direction of the first fin body 111 and the air conditioner 100, ensuring the length of the first fin body 111, thereby ensuring that the first heat exchange pipes 12 along the length direction of the first fin body 111 have sufficient quantity to ensure the heat exchange efficiency, which is conducive to reducing the row number of the first heat exchange pipes 12, the structure is simple, the utilization rate of the first heat exchange pipes 12 is improved, and the manufacturing cost is reduced. At the same time, after arranging the first notch 1111 and the second notch 1112 at the same end of the length direction of the first fin body 111, the width dimension of one end of the first fin body 111 arranged at the first notch 1111 and the second notch 1112 is reduced, and the one end of the first fin body 111 with small width dimension is arranged below, so that the avoidance width of the water pan 20 position opposite to the first fin body 111 can be reduced.

[0064] Further, as shown in Figure 1 , Figure 2 and Figure 6 , the interval distance of the first notch 1111 and the second notch 1112 along the width direction of the first fin body 111 is H1, the width of the first fin body 111 is H, and 1 / 3≤H1 / H≤3 / 4 is satisfied. It can be understood that when the size of the first notch 1111 and the second notch 1112 at the same end of the length direction of the first fin body 111 is too large, it will affect the other structures of the first fin body 111 and the original functions of the first fin body 111 after the first notch 1111 and the second notch 1112 are arranged, for example, the surface area of the first fin body 111 will be greatly reduced, and the number of the first through holes 1113 on the first fin body 111 will also be greatly reduced, thereby reducing the number of the first heat exchange pipes 12, which is not conducive to improving the heat exchange efficiency; and when the size of the first notch 1111 and the second notch 1112 is too small, the installation interference between the corners of the first fin body 111 and the inner wall of the air conditioner 100 still exists, causing the interference between the first fin body 111 and the inner wall of the air conditioner 100. When the relationship between H1 and H satisfies 1 / 3≤H1 / H≤3 / 4, the size of the interval distance of the first notch 1111 and the second notch 1112 at the same end of the length direction of the first fin body 111 along the width direction of the first fin body 111 is within a more reasonable range, so that the utilization rate of the first heat exchange pipes 12 on the first fin body 111 will not be affected, and the interference between the first fin body 111 and the inner wall of the air conditioner 100 is avoided.

[0065] Further, as shown in Figure 1 ,Figure 2 and Figure 6 As shown, the first fin body 111 has a first through hole 1113 for the first heat exchange tube 12 to pass through. Multiple first through holes 1113 in the same row are spaced apart along the length direction of the first fin body 111. The distance between the centers of two adjacent first through holes 1113 in the same row is P. A certain gap is provided between two adjacent first through holes 1113. There is a certain gap between the first heat exchange tubes 12 passing through the first through holes 1113, thereby improving the heat exchange efficiency of the first heat exchanger 1.

[0066] Along the length of the first fin body 111, the length of the first notch 1111 is L11, and satisfies: 1 / 3≤L11 / P≤4 / 3; thus, when the first notch 1111 is set at the corner of the first fin body 111, it is beneficial to make the first notch 1111 avoid the position of the first through hole 1113 on the first fin body 111, which is beneficial to ensure the number of the first through holes 1113 on the first fin body 111, thereby ensuring the heat exchange performance of the first heat exchanger 1.

[0067] Along the length of the first fin body 111, the length of the second notch 1112 is L12, and satisfies: 1 / 3 ≤ L12 / P ≤ 4 / 3. Thus, by setting the second notch 1112 at the corner of the first fin body 111, it is advantageous to ensure that the second notch 1112 avoids the position of the first through hole 1113 on the first fin body 111, thereby ensuring the number of first through holes 1113 on the first fin body 111 and thus guaranteeing the heat exchange performance of the first heat exchanger 1.

[0068] In some embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 6 As shown, along the length direction of the first fin body 111, the length of the first notch 1111 is L11, and the length of the second notch 1112 is L12, satisfying: L11 = L12. It can be understood that the first fin bodies 111 are closely arranged on the raw material before cutting. Multiple rows of first fin bodies 111 are arranged along the length direction of the first fin body 111 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 first fin bodies 111, 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 first fin body 111 have the same length. In this way, one edge of two first fin bodies 111 can be cut out in one cut, improving the production efficiency of the first fin body 111.

[0069] In some embodiments of this utility model, such as Figure 1 ,Figure 2 and Figure 6 As shown in FIG. 6, two corners of the length direction of the second fin body 211 away from the one end of the first fin body 111 are respectively provided with a third notch 2111 and a fourth notch 2112, the third notch 2111 and the fourth notch 2112 are spaced apart in the width direction of the second fin body 211 (such as the fourth direction shown in FIG. 6), the interval distance of the third notch 2111 and the fourth notch 2112 along the width direction of the second fin body 211 is H2, the width of the second fin body 211 is H0, and it satisfies: 1 / 3≤H2 / H0≤3 / 4. Figure 1

[0070] Specifically, the second fin body 211 being rectangular means that the overall contour of the second fin body 211 is basically rectangular, for example, basically rectangular without considering the third notch 2111 and the fourth notch 2112.

[0071] The second fin body 211 is provided with a second through hole 2113 for the second heat exchange pipe 22 to pass through, the second heat exchange pipe 22 is arranged in the second through hole 2113, in order to avoid the installation interference between the corners of the second fin body 211 and the inner wall of the air conditioner 100 when the second heat exchanger 2 is installed, it is usually to reduce the length of the second fin body 211 to achieve, at the same time, increase the row number of the second heat exchange pipe 22 along the width direction of the second fin body 211 in the second heat exchanger 2 to ensure the heat exchange efficiency of the second heat exchanger 2, but increasing the row number of the second heat exchange pipe 22 along the width direction of the second fin body 211 in the second heat exchanger 2 is easy to cause the utilization rate of the second heat exchange pipe 22 is not high, resulting in waste, and high cost.

[0072] ​Therefore, by setting the third notch 2111 and the fourth notch 2112, the area of the two corners of the one end of the second fin body 211 away from the first fin body 111 in the length direction of the second fin body 211 can be reduced, thereby reducing the installation interference between the two corners of the one end of the second fin body 211 away from the first fin body 111 in the length direction of the second fin body 211 and the air conditioner 100, ensuring the length of the second fin body 211, thereby ensuring that the second heat exchange pipes 22 in the second heat exchanger 2 along the length direction of the second fin body 211 have sufficient quantity to ensure the heat exchange efficiency, which is beneficial to reducing the number of rows of the second heat exchange pipes 22, the structure is simple, the utilization rate of the second heat exchange pipes 22 is improved, and the manufacturing cost is reduced. At the same time, the use of the second fin body 211 is further reduced, and the production cost of the second heat exchanger 2 is reduced. At the same time, after the third notch 2111 and the fourth notch 2112 are arranged at the one end of the second fin body 211 away from the first fin body 111 in the length direction of the second fin body 211, the width dimension of the one end of the second fin body 211 arranged at the third notch 2111 and the fourth notch 2112 is reduced, and the one end of the second fin body 211 with a small width dimension is arranged below, so that the avoidance width of the water pan 20 position opposite to the second fin body 211 can be reduced.

[0073] Further, H1=H2. It should be noted that when producing the first fin body 111 and the second fin body 211, a plurality of rows of the first fin body 111 and the second fin body 211 are arranged on the raw material along the length direction of the first fin body 111 and the second fin body 211, and need to be cut, in order to improve the utilization rate of the raw material, the edges of the two rows of the first fin body 111 and the second fin body 211 in the length direction except the first notch 1111, the second notch 1112, the third notch 2111 and the fourth notch 2112 are coincided with each other, when H1=H2, the edge size of the one end of the first fin body 111 in the length direction and the one end of the second fin body 211 in the length direction is the same and coincided with each other, so that one edge of the one end of the first fin body 111 in the length direction and the one end of the second fin body 211 in the length direction can be cut respectively by one cutting, and the production efficiency of the first fin body 111 and the second fin body 211 is improved.

[0074] Further, H=H0. It should be noted that the width of the first fin body 111 and the second fin body 211 is the same, and when producing the first fin body 111 and the second fin body 211, the width of the first fin body 111 and the second fin body 211 can be cut by one cutting, without cutting the width respectively, and the production efficiency of the first fin body 111 and the second fin body 211 is improved.

[0075] In some embodiments of the present application, Figure 1 ,Figure 2 and Figure 6 As shown in the figure, the second fin body 211 has a plurality of rows of second through holes 2113 for the second heat exchange pipe 22 to pass through, the second through holes 2113 in the same row are arranged at intervals along the length direction of the second fin body 211, the distance between the centers of two adjacent second through holes 2113 in the same row is P0, a certain interval is arranged between the two adjacent second through holes 2113, and a certain gap is arranged between the second heat exchange pipes 22 passing through the second through holes 2113, so that the heat exchange efficiency of the second heat exchanger 2 is improved.

[0076] The length of the third gap 2111 along the length direction of the second fin body 211 is L21, and satisfies: 1 / 3≤L21 / P0≤4 / 3; in this way, when the third gap 2111 is arranged at the corner of the second fin body 211, the third gap 2111 is beneficial to avoid the position of the second through hole 2113 on the second fin body 211, and is beneficial to ensure the number of the second through hole 2113 on the second fin body 211, and further ensure the heat exchange performance of the second heat exchanger 2.

[0077] The length of the fourth gap 2112 along the length direction of the second fin body 211 is L22, and satisfies: 1 / 5≤L22 / P0≤1; in this way, when the fourth gap 2112 is arranged at the corner of the second fin body 211, the fourth gap 2112 is beneficial to avoid the position of the second through hole 2113 on the second fin body 211, and is beneficial to ensure the number of the second through hole 2113 on the second fin body 211, and further ensure the heat exchange performance of the second heat exchanger 2.

[0078] In some embodiments of the utility model, P=P0. When the first fin body 111 and the second fin body 211 are produced, the tool does not need to be changed, and the first through hole 1113 and the second through hole 2113 on the first fin body 111 and the second fin body 211 can be cut, so that the production efficiency of the first fin body 111 and the second fin body 211 is improved.

[0079] In some embodiments of the utility model, along the length direction of second fin body 211, the length of third gap 2111 is L21, the length of fourth gap 2112 is L22, and satisfy: L21=L22. It can be understood that, as shown in the figure, second fin body 211 is closely arranged on the raw material before cutting, and multiple columns of second fin body 211 are arranged on the raw material along the length direction of second fin body 211, and need to be cut, in order to reduce the cutting loss of raw material and improve the utilization rate of raw material, the edges of two rows of adjacent second fin body 211 in the width direction of the raw material are arranged to coincide except for the gap, when L11=L12, the length of the mutually coinciding edges of the two ends of second fin body 211 in the width direction is same, in this way, through once cutting, one edge of two second fin body 211 can be cut respectively, and the production efficiency of second fin body 211 is improved.

[0080] In some embodiments of the utility model, as shown in Figure 2 、 Figure 6 and Figure 7 , the shapes of first gap 1111, second gap 1112, third gap 2111 and fourth gap 2112 are same or different, it can be understood that, the shapes of first gap 1111, second gap 1112, third gap 2111 and fourth gap 2112 are all same, or the shapes of three of first gap 1111, second gap 1112, third gap 2111 and fourth gap 2112 are same, or the shapes of two of first gap 1111, second gap 1112, third gap 2111 and fourth gap 2112 are same, or the shapes of each of first gap 1111, second gap 1112, third gap 2111 and fourth gap 2112 are different. The first gap 1111, the second gap 1112, the third gap 2111 and the fourth gap 2112 on the first fin body 111 and the second fin body 211 are arranged to be same, which is beneficial to simplify the overall structure shape of the first fin body 111 and the second fin body 211, and reduce the production and processing difficulty of the first fin body 111 and the second fin body 211; the first gap 1111, the second gap 1112, the third gap 2111 and the fourth gap 2112 on the first fin body 111 and the second fin body 211 are arranged to be different, which is beneficial to distinguish the direction of the first fin body 111 and the second fin body 211, and prevent errors during installation. The shapes of first gap 1111, second gap 1112, third gap 2111 and fourth gap 2112 can be selected according to design requirements to meet different application scenarios.

[0083] The number of through holes of the row of first through holes 1113 or second through holes 2113 closest to one side edge in the width direction of the first fin body 111 or the second fin body 211 is the same as or different from the number of through holes of the row of first through holes 1113 or second through holes 2113 closest to the other side edge in the width direction of the first fin body 111 or the second fin body 211. It can be understood that the number of through holes of the row of first through holes 1113 or second through holes 2113 closest to one side edge in the width direction of the first fin body 111 or the second fin body 211 is the same as the number of through holes of the row of first through holes 1113 or second through holes 2113 closest to the other side edge in the width direction of the first fin body 111 or the second fin body 211, or the number of through holes of the row of first through holes 1113 or second through holes 2113 closest to one side edge in the width direction of the first fin body 111 or the second fin body 211 is different from the number of through holes of the row of first through holes 1113 or second through holes 2113 closest to the other side edge in the width direction of the first fin body 111 or the second fin body 211.

[0085] By reasonably arranging the outer contour of at least one of the first gap 1111, the second gap 1112, the third gap 2111 and the fourth gap 2112 of the first fin body 111 and the second fin body 211, the shape of the first gap 1111, the second gap 1112, the third gap 2111 and the fourth gap 2112 can be matched with the installation space of the air conditioner 100. Meanwhile, the material of the first fin body 111 and the second fin body 211 is further reduced while ensuring the heat exchange performance and the number of the first heat exchange pipe 12 and the second heat exchange pipe 22 is ensured, thereby reducing the production cost.

[0086] In some embodiments of the utility model, as shown in Figure 1 , Figure 2 and Figure 4As shown in the first gap 1111, the second gap 1112, the third gap 2111 and the fourth gap 2112, the outer contour of at least one of them comprises a third straight line segment 212, a fourth straight line segment 213, a first arc segment 214, a second inclined segment 215, a fifth straight line segment 216 and a sixth straight line segment 217 connected in turn, the third straight line segment 212, the second inclined segment 215 and the fifth straight line segment 216 are arranged in turn in the length direction of the first fin body 111 or the second fin body 211, the third straight line segment 212 and the fifth straight line segment 216 extend along the length direction of the first fin body 111 or the second fin body 211, the fourth straight line segment 213 and the sixth straight line segment 217 extend along the width direction of the first fin body 111 or the second fin body 211, the end of the third straight line segment 212 away from the fourth straight line segment 213 is connected with the edge of the first fin body 111 or the second fin body 211 in the width direction, the end of the second inclined segment 215 away from the first arc segment 214 extends obliquely towards one side of the first fin body 111 or the second fin body 211 in the width direction, the first arc segment 214 bends towards the inside of the first fin body 111 or the second fin body 211, and the end of the sixth straight line segment 217 away from the fifth straight line segment 216 is connected with the edge of the first fin body 111 or the second fin body 211 in the length direction.

[0087] By reasonably arranging the outer contour of at least one of the first gap 1111, the second gap 1112, the third gap 2111 and the fourth gap 2112 of the first fin body 111 and the second fin body 211, the shape of the first gap 1111, the second gap 1112, the third gap 2111 and the fourth gap 2112 can be matched with the installation space of the air conditioner 100. At the same time, the material of the first fin body 111 and the second fin body 211 is further reduced while ensuring the heat exchange performance, and the number of the first heat exchange pipe 12 and the second heat exchange pipe 22 is ensured, thereby reducing the production cost.

[0088] In some embodiments of the utility model, as shown in Figure 1 , Figure 2 and Figure 7 As shown in the length direction of the first fin body 111, the two corners of the end close to the second fin body 211 are respectively provided with a fifth gap 1114 and a sixth gap 1115, the fifth gap 1114 and the sixth gap 1115 are spaced apart in the width direction of the first fin body 111, the interval distance of the fifth gap 1114 and the sixth gap 1115 along the width direction of the first fin body 111 is H3, and satisfies: 1 / 4≤H3 / H≤1 / 2.

[0089] By setting the fifth notch 1114 and the sixth notch 1115, the area of the two corners of the first fin body 111 at the end close to the second fin body 211 in the length direction of the first fin body 111 can be reduced, thereby reducing the installation interference between the two corners of the first fin body 111 at the end close to the second fin body 211 in the length direction of the first fin body 111 and the air conditioner 100, ensuring the length of the first fin body 111, thereby ensuring that there is a sufficient number of first heat exchange pipes 12 in the first heat exchanger 1 along the length direction of the first fin body 111 to ensure the heat exchange efficiency, which is conducive to reducing the number of rows of the first heat exchange pipes 12, the structure is simple, the utilization rate of the first heat exchange pipes 12 is improved, and the manufacturing cost is reduced. At the same time, the use of the first fin body 111 is also further reduced, and the production cost of the first heat exchanger 1 is reduced. At the same time, after the fifth notch 1114 and the sixth notch 1115 are arranged at the same end in the length direction of the first fin body 111, the width dimension of the first fin body 111 at the end where the fifth notch 1114 and the sixth notch 1115 are arranged is reduced, and the end with a smaller width dimension of the first fin body 111 is arranged below, which can reduce the avoidance width of the water pan 20 position opposite to the first fin body 111.

It can be understood that when the size of the fifth notch 1114 and the sixth notch 1115 at the end close to the second fin body 211 in the length direction of the first fin body 111 is too large, it will affect the other structures of the first fin body 111 and the original functions of the first fin body 111 after the fifth notch 1114 and the sixth notch 1115 are arranged, for example, the surface area of the first fin body 111 will be greatly reduced, and the number of the first through holes 1113 on the first fin body 111 will also be greatly reduced, thereby reducing the number of the first heat exchange pipes 12, which is not conducive to improving the heat exchange efficiency; and when the size of the fifth notch 1114 and the sixth notch 1115 is too small, the installation interference between the corners of the first fin body 111 and the inner wall of the air conditioner 100 still exists, causing the interference between the first fin body 111 and the inner wall of the air conditioner 100. When the relationship between H3 and H satisfies 1 / 4≤H3 / H≤1 / 2, the size of the interval distance of the fifth notch 1114 and the sixth notch 1115 along the width direction of the first fin body 111 at the end close to the second fin body 211 in the length direction of the first fin body 111 is within a more reasonable range, so that the utilization rate of the first heat exchange pipes 12 on the first fin body 111 is not affected, and the interference between the first fin body 111 and the inner wall of the air conditioner 100 is also avoided.

[0091] In some embodiments of the utility model, as shown in Figure 1 、 Figure 2 and Figure 7 , the first fin body 111 has a plurality of rows of first through holes 1113 for the first heat exchange pipe 12 to pass through, the first through holes 1113 in the same row are arranged at intervals along the length direction of the first fin body 111, the distance between the centers of two adjacent first through holes 1113 in the same row is P, a certain interval is provided between the two adjacent first through holes 1113, and a certain gap is provided between the first heat exchange pipes 12 arranged on the first through holes 1113, thereby improving the heat exchange efficiency of the first heat exchanger 1.

[0092] Along the length direction of the first fin body 111, the length of the fifth gap 1114 is L31, and 1 / 3≤L31 / P≤4 / 3 is satisfied; in this way, when the fifth gap 1114 is arranged at the corner of the first fin body 111, the fifth gap 1114 is beneficial to avoid the position of the first through hole 1113 on the first fin body 111, which is beneficial to ensure the number of the first through hole 1113 on the first fin body 111, and further ensure the heat exchange performance of the first heat exchanger 1.

[0093] Along the length direction of the first fin body 111, the length of the sixth gap 1115 is L32, and 1 / 2≤L32 / P≤4 / 3 is satisfied; in this way, when the sixth gap 1115 is arranged at the corner of the first fin body 111, the sixth gap 1115 is beneficial to avoid the position of the first through hole 1113 on the first fin body 111, which is beneficial to ensure the number of the first through hole 1113 on the first fin body 111, and further ensure the heat exchange performance of the first heat exchanger 1.

[0094] In some embodiments of the utility model, as shown in Figure 1 、 Figure 2 and Figure 7 , the two corners of the length direction of the second fin body 211 close to the first fin body 111 are respectively provided with a seventh gap 2114 and an eighth gap 2115, and the seventh gap 2114 and the eighth gap 2115 are spaced apart in the width direction of the second fin body 211.

[0095] By setting the seventh gap 2114 and the eighth gap 2115, the area of the two corners of the second fin body 211 near the one end of the length direction of the second fin body 211 close to the first fin body 111 can be reduced, thereby reducing the installation interference between the two corners of the second fin body 211 near the one end of the length direction of the second fin body 211 close to the first fin body 111 and the air conditioner 100, ensuring the length of the second fin body 211, thereby ensuring that the second heat exchange pipes 22 in the second heat exchanger 2 along the length direction of the second fin body 211 have sufficient quantity to ensure the heat exchange efficiency, which is conducive to reducing the number of rows of the second heat exchange pipes 22, the structure is simple, the utilization rate of the second heat exchange pipes 22 is improved, and the manufacturing cost is reduced. At the same time, the use of the second fin body 211 is also further reduced, and the production cost of the second heat exchanger 2 is reduced. At the same time, after setting the seventh gap 2114 and the eighth gap 2115 at the one end of the length direction of the second fin body 211 close to the first fin body 111, the width dimension of the one end of the second fin body 211 close to the first fin body 111 is reduced, and the one end of the second fin body 211 with small width dimension is arranged below, which can reduce the avoidance width of the water pan 20 position opposite to the second fin body 211.

[0096] The second fin body 211 has a plurality of second through holes 2113 for the second heat exchange pipes 22 to pass through, and the plurality of second through holes 2113 in the same row are arranged at intervals along the length direction of the second fin body 211. The distance between the centers of the two adjacent second through holes 2113 in the same row is P0, and a certain spacing is provided between the two adjacent second through holes 2113. The second heat exchange pipes 22 arranged on the second through holes 2113 have a certain gap therebetween, thereby improving the heat exchange efficiency of the second heat exchanger 2.

[0097] Along the length direction of the second fin body 211, the length of the seventh gap 2114 is L41, and satisfies: 1 / 2≤L41 / P0≤4 / 3. In this way, when the seventh gap 2114 is arranged at the corner of the second fin body 211, the seventh gap 2114 is beneficial to avoid the position of the second through hole 2113 on the second fin body 211, which is beneficial to ensure the number of the second through hole 2113 on the second fin body 211, and further ensure the heat exchange performance of the second heat exchanger 2.

[0098] Along the length direction of the second fin body 211, the length of the eighth gap 2115 is L42, and satisfies: 1 / 2≤L42 / P0≤3 / 4. In this way, when the eighth gap 2115 is arranged at the corner of the second fin body 211, the eighth gap 2115 is beneficial to avoid the position of the second through hole 2113 on the second fin body 211, which is beneficial to ensure the number of the second through hole 2113 on the second fin body 211, and further ensure the heat exchange performance of the second heat exchanger 2.

It can be understood that, as shown in the figure, the first fin body 111 and / or the second fin body 211 are closely arranged on the raw material before cutting, and a plurality of rows of first fin bodies 111 and / or second fin bodies 211 are arranged on the raw material along the length direction of the first fin body 111 and / or the second fin body 211, and need to be cut, in order to reduce the cutting loss of the raw material and improve the utilization rate of the raw material, on the raw material, the edges of the two ends of the width direction of the two adjacent first fin bodies 111 and / or second fin bodies 211 are arranged to coincide except for the notch, when L32=L42, the length of the mutually coinciding edges of the two ends of the width direction of the first fin body 111 and / or the second fin body 211 is the same, in this way, through one cutting, one edge of two first fin bodies 111 and / or second fin bodies 211 can be cut respectively, and the production efficiency of the first fin body 111 and / or the second fin body 211 is improved.

[0101] In some embodiments of the utility model, as shown in Figure 1 and Figure 2 The sixth notch 1115 and the eighth notch 2115 are at least partially fitted. The first fin 11 and the second fin 21 can be connected together more sealingly, avoiding the airflow directly flowing out of the heat exchanger assembly 10 from the gap between the first fin 11 and the second fin 21, avoiding affecting the heat exchange effect of the heat exchanger assembly 10.

[0102] Further, the side of the sixth notch 1115 away from the second notch 1112 is provided with a first protrusion 11151, the side of the eighth notch 2115 away from the fourth notch 2112 is provided with a second protrusion 21151, and at least part of the free end faces of the first protrusion 11151 and the second protrusion 21151 abut. It can be understood that the first protrusion 11151 and the second protrusion 21151 are formed at the connection positions of the first fin 11 and the second fin 21, facilitating the splicing or connection of one end of the plurality of second fins 21 in the length direction and one end of the plurality of first fins 11 in the length direction, so as to form the heat exchanger assembly 10 with a larger heat exchange area, and improve the heat exchange performance of the heat exchanger assembly 10.

By arranging the fifth notch 1114 and the seventh notch 2114, the area of the two corners of the one end of the first fin body 111 and the second fin body 211 in the length direction can be reduced, thereby reducing the installation interference between the two corners of the one end of the first fin body 111 and the second fin body 211 in the length direction, ensuring the length of the first fin body 111 and the second fin body 211, thereby ensuring that there are enough numbers of the first heat exchange pipe 12 and the second heat exchange pipe 22 in the heat exchanger assembly 10 to ensure the heat exchange efficiency, which is conducive to reducing the row number of the first heat exchange pipe 12 and the second heat exchange pipe 22, and the structure is simple, the utilization rate of the first heat exchange pipe 12 and the second heat exchange pipe 22 is improved, and the manufacturing cost is reduced. At the same time, the use of the first fin body 111 and the second fin body 211 is further reduced, and the production cost of the first heat exchanger 1 and the second heat exchanger 2 is reduced.

[0104] and satisfies: 1 / 6≤H31 / H≤1 / 3. It can be understood that when the size of the width of the fifth gap 1114 along the width direction of the first fin body 111 and the width of the seventh gap 2114 along the width direction of the second fin body 211 is too large, it will affect the other structures of the first fin body 111 and the second fin body 211 and the original functions of the first fin body 111 and the second fin body 211 after setting the fifth gap 1114 and the seventh gap 2114, for example, it will greatly reduce the surface area of the first fin body 111 and the second fin body 211, and also greatly reduce the number of first through holes 1113 on the first fin body 111 and the number of second through holes 2113 on the second fin body 211, thereby reducing the number of first heat exchange pipes 12 and second heat exchange pipes 22, which is not conducive to improving the heat exchange efficiency; and when the size of the fifth gap 1114 and the seventh gap 2114 is too small, the installation interference between the first fin body 111 and the second fin body 211 still exists, causing the inner wall interference of the first fin body 111 and the second fin body 211. When the relationship between H31 and H satisfies: 1 / 6≤H31 / H≤1 / 3, the size of the width of the fifth gap 1114 along the width direction of the first fin body 111 and the width of the seventh gap 2114 along the width direction of the second fin body 211 is within a more reasonable range, so that the utilization rate of the first heat exchange pipe 12 on the first fin body 111 and the utilization rate of the second heat exchange pipe 22 on the second fin body 211 will not be affected.

When the relationship between H32 and H satisfies: 1 / 10≤H32 / H≤1 / 6, the size of the width of the first protrusion 11151 along the width direction of the first fin body 111 and the width of the second protrusion 21151 along the width direction of the second fin body 211 is within a more reasonable range, so that the utilization rate of the first heat exchange pipe 12 on the first fin body 111 and the utilization rate of the second heat exchange pipe 22 on the second fin body 211 will not be affected.

[0106] In some embodiments of the utility model, as shown in Figure 1 、 Figure 2 and Figure 7 The minimum distance between the first protrusion 11151 and the edge of the first fin body 111 in the width direction without the fifth gap 1114 and the minimum distance between the second protrusion 21151 and the edge of the second fin body 211 in the width direction without the seventh gap 2114 are both H33, and satisfy: 1 / 6≤H33 / H≤1 / 3.

[0107] It can be understood that when the minimum distance between the first protrusion 11151 and the edge of the first fin body 111 in the width direction without the fifth gap 1114 and the minimum distance between the second protrusion 21151 and the edge of the second fin body 211 in the width direction without the seventh gap 2114 are too large, it will affect the other structures of the first fin body 111 and the second fin body 211 and the original functions of the first fin body 111 and the second fin body 211 after the sixth gap 1115 and the eighth gap 2115 are arranged, for example, the surface area of the first fin body 111 and the second fin body 211 will be greatly reduced, and the number of the first through holes 1113 on the first fin body 111 and the number of the second through holes 2113 on the second fin body 211 will also be greatly reduced, thereby reducing the number of the first heat exchange pipe 12 and the second heat exchange pipe 22, which is not conducive to improving the heat exchange efficiency; and when the minimum distance between the first protrusion 11151 and the edge of the first fin body 111 in the width direction without the fifth gap 1114 and the minimum distance between the second protrusion 21151 and the edge of the second fin body 211 in the width direction without the seventh gap 2114 are too small, there will still be installation interference between the first fin body 111 and the second fin body 211, causing the inner wall interference of the first fin body 111 and the second fin body 211. When the relationship between H33 and H satisfies: 1 / 6≤H33 / H≤1 / 3, the minimum distance between the first protrusion 11151 and the edge of the first fin body 111 in the width direction without the fifth gap 1114 and the minimum distance between the second protrusion 21151 and the edge of the second fin body 211 in the width direction without the seventh gap 2114 are within a more reasonable range, so that the utilization rate of the first heat exchange pipe 12 on the first fin body 111 and the utilization rate of the second heat exchange pipe 22 on the second fin body 211 will not be affected.

[0109] In some embodiments of the present application, along the width direction of the second fin body 211, the second protrusion 21151 is arranged at the middle part of the eighth gap 2115 and is spaced apart from the edge of the eighth gap 2115 in the width direction, so that there is a tool withdrawal gap between the second protrusion 21151 and the edge of the eighth gap 2115 in the width direction, facilitating the machining and manufacturing of the second protrusion 21151.

[0111] By reasonably arranging the outer contour of the seventh gap 2114 of the second fin body 211, the shape of the seventh gap 2114 is matched with the installation space of the air conditioner 100. At the same time, under the condition of ensuring the heat exchange performance, the material of the second fin body 211 is further reduced and the number of the second heat exchange pipes 22 is ensured, thereby reducing the production cost.

After the third notch 2111 or the fourth notch 2112 or the seventh notch 2114 or the eighth notch 2115 is arranged on the second fin body 211, the flow velocity distribution of the air flow between the second fin body 211 and the second heat exchange pipe 22 is more uniform, the heat exchange efficiency of the air flow between the second fin body 211 and the second heat exchange pipe 22 is improved, although the second through hole 2113 close to the corner of the second fin body 211 is cut off, the number of the second heat exchange pipe 22 is reduced, but since the heat exchange efficiency of the second heat exchange pipe 22 is improved, the heat exchange performance of the second heat exchanger 2 is improved.

[0125] The heat exchanger assembly 10 according to one specific embodiment of the present application will be described below with reference to the accompanying drawings. It should be understood that the following description is only exemplary and is intended to explain the present application, but cannot be understood as a limitation of the present application.

[0126] Specifically, as shown in Figure 1 and Figure 2 The heat exchanger assembly 10 includes a first heat exchanger 1 and a second heat exchanger 2.

By arranging the first notch 1111 and the second notch 1112, the area of the two corners of the same end in the length direction of the first fin body 111 can be reduced, thereby reducing the installation interference between the two corners of the same end in the length direction of the first fin body 111 and the air conditioner 100, ensuring the length of the first fin body 111, thereby ensuring that there are enough first heat exchange pipes 12 in the first heat exchanger 1 along the length direction of the first fin body 111 to ensure the heat exchange efficiency, which is conducive to reducing the number of rows of the first heat exchange pipes 12, the structure is simple, the utilization rate of the first heat exchange pipes 12 is improved, and the manufacturing cost is reduced. At the same time, the use of the first fin body 111 is further reduced, and the production cost of the first heat exchanger 1 is reduced. At the same time, after arranging the first notch 1111 and the second notch 1112 at the same end in the length direction of the first fin body 111, the width dimension of the one end of the first fin body 111 arranged at the first notch 1111 and the second notch 1112 is reduced, and the one end of the first fin body 111 with a small width dimension is arranged below, so that the avoidance width of the water pan 20 position opposite to the first fin body 111 is reduced.

[0131] The first fin body 111 has a first through hole 1113 for the first heat exchange pipe 12 to pass through, a plurality of first through holes 1113 in the same row are arranged at intervals along the length direction of the first fin body 111, the distance between the centers of two adjacent first through holes 1113 in the same row is P, a certain spacing is arranged between the two adjacent first through holes 1113, and a certain gap is arranged between the first heat exchange pipes 12 arranged on the first through hole 1113, thereby improving the heat exchange efficiency of the first heat exchanger 1.

The second fin body 211 is provided with a second through hole 2113 for the second heat exchange pipe 22 to pass through, the second heat exchange pipe 22 is arranged in the second through hole 2113, in order to avoid the installation interference between the corners of the second fin body 211 and the inner wall of the air conditioner 100 when the second heat exchanger 2 is installed, the length of the second fin body 211 is usually reduced to achieve, and the number of rows of the second heat exchange pipe 22 in the second heat exchanger 2 along the width direction of the second fin body 211 is increased to ensure the heat exchange efficiency of the second heat exchanger 2, but increasing the number of rows of the second heat exchange pipe 22 in the second heat exchanger 2 along the width direction of the second fin body 211 is easy to cause the utilization rate of the second heat exchange pipe 22 to be not high, causing waste and high cost.

[0133] Therefore, by arranging the third notch 2111 and the fourth notch 2112, the area of the two corners of the length direction of the second fin body 211 away from one end of the first fin body 111 can be reduced, thereby reducing the installation interference between the two corners of the length direction of the second fin body 211 away from one end of the first fin body 111 and the air conditioner 100, ensuring the length of the second fin body 211, thereby ensuring that there is a sufficient number of second heat exchange pipes 22 in the second heat exchanger 2 along the length direction of the second fin body 211 to ensure the heat exchange efficiency, which is conducive to reducing the number of rows of the second heat exchange pipe 22, the structure is simple, the utilization rate of the second heat exchange pipe 22 is improved, and the manufacturing cost is reduced.
