For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0050] A heat exchanger assembly 10 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0051] like Figure 1 As shown, the heat exchanger assembly 10 according to an embodiment of the present invention includes a front heat exchanger 1 and a rear heat exchanger 2 .

[0052] Specifically, the heat exchanger can be used in an air conditioner 100, which includes a fan 20. For example, the air conditioner 100 is used indoors. The heat exchanger absorbs heat from the indoor air and transfers it to the outside, or transfers heat from the outside to the indoor, through a circulating refrigerant (such as Freon), thereby regulating the indoor temperature. The heat exchanger is a key device for heat transfer in the air conditioner 100. In cooling mode, the heat exchanger evaporates the refrigerant at low pressure, absorbing heat from the indoor air and lowering the indoor temperature. In heating mode, the refrigerant condenses at high temperature and high pressure through the condenser, releasing heat and transferring the heat to the indoor air, raising the indoor temperature.

[0053] like Figure 1 and Figure 2 As shown, the rear heat exchanger 2 is located at the rear side of the front heat exchanger 1 (as shown in FIG. Figure 1The rear heat exchanger 2 includes a plurality of first fins 21 spaced apart in the longitudinal direction of the rear heat exchanger 2 and a first heat exchange tube 22 passing through the plurality of first fins 21. By providing the plurality of spaced apart first fins 21, the first heat exchange tube 22 can be fixed at a plurality of positions on the rear heat exchanger 2, so that the position of the first heat exchange tube 22 on the rear heat exchanger 2 can be more reliable, and the installation of the first heat exchange tube 22 can be more reliable.

[0054] Among them, the length direction of the rear heat exchanger 2 is the same as that of the attached Figure 1 The first heat exchange tube 22 includes a straight tube section and connecting tubes connected to both ends of the straight tube section. The connecting tubes are used to connect two adjacent first heat exchange tubes 22 or the inlet and outlet pipes of the heat exchanger assembly 10. The connecting tubes can be U-shaped tubes or half U-shaped tubes.

[0055] The heat exchange medium flowing in the first heat exchange tube 22 can transfer heat to the first fin 21, thereby increasing the heat exchange area of ​​the rear heat exchanger 2. For example, in cooling mode, refrigerant flows in the first heat exchange tube 22, and the cooling energy of the refrigerant can be dissipated to the first fin 21 through the first heat exchange tube 22. External air enters the air conditioner 100, flows toward the rear heat exchanger 2, and exchanges heat with the refrigerant in the first heat exchange tube 22. The refrigerant in the first heat exchange tube 22 evaporates and absorbs heat. At the same time, the airflow can also exchange heat with the first fin 21. The airflow gradually cools and flows out of the air outlet 302 driven by the wind wheel 20.

[0056] like Figure 1 and Figure 2 As shown, the lower end of the first fin 21 (as shown Figure 1 The upper and lower directions shown in the figure have an overlapping area 211, and the overlapping area 211 is provided with reinforcing ribs 2111, which can strengthen the strength of the edge of the first fin 21; at the same time, the condensation water generated during the heat exchange process can drip along the overlapping area 211, which can take into account the frost problem of the air conditioner 100 and make the overlapping area 211 of the first fin 21 easier to defrost.

[0057] According to the heat exchanger assembly 10 of the present embodiment, by inserting the first heat exchange tubes 22 through a plurality of first fins 21 spaced apart along the length of the rear heat exchanger 2, the heat exchange medium flowing in the first heat exchange tubes 22 can transfer heat to the first fins 21, thereby increasing the heat exchange area of ​​the rear heat exchanger 2. Furthermore, the lower ends of the first fins 21 have overlapping regions 211, which are provided with reinforcing ribs 2111 to strengthen the edges of the first fins 21 and prevent deformation of the overlapping regions 211. Condensation generated during the heat exchange process can drip along the overlapping regions 211, thereby addressing the frost problem of the air conditioner 100 and making the overlapping regions 211 of the first fins 21 easier to defrost.

[0058] In some embodiments of the present invention, the distance between the lower end of the overlapping region 211 (i.e., the lower end of the first fin 21) and the adjacent first heat exchange tube 22 is greater than the distance between two adjacent first heat exchange tubes 22. The adjacent first heat exchange tube 22 refers to the first heat exchange tube 22 closest to the lower end of the overlapping region 211; the distance between the lower end of the overlapping region 211 and the adjacent first heat exchange tube 22 refers to the distance between the lower end of the overlapping region 211 and the central axis of the straight section of the adjacent first heat exchange tube 22; the distance between two adjacent first heat exchange tubes 22 can be the distance between the central axes of the straight sections of the two connected first heat exchange tubes 22, or the distance between the central axes of the straight sections of the two closest first heat exchange tubes 22. The distance between the lower end of the overlapping region 211 and the adjacent first heat exchange tube 22 is greater than the distance between the two adjacent first heat exchange tubes 22, thereby facilitating the support of the rear heat exchanger 2 on the air conditioner housing 30 via the overlapping region 211. In addition, reinforcing ribs 2111 are provided in the overlapping region 211 to reduce deformation of the overlapping region 211 .

[0059] In some embodiments of the present invention, there are multiple reinforcing ribs 2111 spaced apart, and multiple reinforcing ribs 2111 can improve the strength of the first fin 21 at multiple locations. The reinforcing effect of the reinforcing ribs 2111 is better. Multiple reinforcing ribs 2111 are arranged at intervals along the width direction of the first fin 21. Along the thickness direction of the first fin 21, the reinforcing ribs 2111 protrude from the first fin 21, which can increase the cross-sectional area of ​​the first fin 21 and significantly improve the strength and rigidity of the first fin 21.

[0060] Furthermore, if Figure 1 、 Figure 6 and Figure 7 As shown, along the thickness direction of the first fin 21, multiple reinforcing ribs 2111 protrude toward the same side, making the processing and manufacturing of the reinforcing ribs 2111 more convenient. Alternatively, at least two of the multiple reinforcing ribs 2111 protrude toward both sides of the thickness direction of the first fin 21, which can reduce the risk of deformation of the first fin 21 and improve the flatness of the first fin 21.

[0061] Furthermore, the number of reinforcing ribs 2111 is 3-8. It is understood that the number of reinforcing ribs 2111 can be 3, 4, 5, 6, 7, or 8. The number of reinforcing ribs 2111 is no less than 3 to ensure the reinforcing effect of the reinforcing ribs 2111, significantly improving the strength and rigidity of the first fin 21. The number of reinforcing ribs 2111 is no more than 8 to avoid overly complex processing and manufacturing of the first fin 21, thereby reducing the manufacturing cost of the first fin 21.

[0062] In some embodiments of the present invention, the heights of the multiple reinforcing ribs 2111 are the same or different. It is understood that when the multiple reinforcing ribs 2111 have the same height, the ribs 2111 can be processed uniformly through stamping and other steps, simplifying the manufacture of the reinforcing ribs 2111 and reducing the manufacturing cost of the first fin 21. The heights of the multiple reinforcing ribs 2111 can be designed based on the shape of the first fin 21, further strengthening the edge strength of the first fin 21. Condensation generated during heat exchange can drip along the first fin 21, making it easier to defrost the first fin 21. The heights of the multiple reinforcing ribs 2111 can be selected as needed to meet different usage requirements.

[0063] In some embodiments of the present invention, along the width direction of the first fin 21, such as Figure 5 、 Figure 6 and Figure 7 As shown, the distance between any two adjacent reinforcing ribs 2111 among the multiple reinforcing ribs 2111 is the same or different. It is understandable that along the width direction of the first fin 21, the distance between any two adjacent reinforcing ribs 2111 among the multiple reinforcing ribs 2111 is the same, and the reinforcing ribs 2111 can be processed by uniformly performing steps such as stamping. The manufacturing of the reinforcing ribs 2111 is relatively simple, reducing the manufacturing cost of the first fin 21. Along the width direction of the first fin 21, the distance between any two adjacent reinforcing ribs 2111 among the multiple reinforcing ribs 2111 is different. The distance between any two adjacent reinforcing ribs 2111 can be designed according to the shape of the first fin 21 to better strengthen the strength of the edge of the first fin 21, and the condensation water generated during the heat exchange process can drip along the first fin 21, making the first fin 21 easier to defrost. The distance between any two adjacent reinforcing ribs 2111 can be selected according to demand to meet different usage requirements.

[0064] In some embodiments of the present invention, Figure 6 and Figure 7 As shown, along the width direction of the first fin 21, the widths of the multiple reinforcing ribs 2111 are the same or different. It is understandable that along the width direction of the first fin 21, the widths of the multiple reinforcing ribs 2111 are the same, and the reinforcing ribs 2111 can be processed uniformly through stamping and other steps. The manufacturing of the reinforcing ribs 2111 is relatively simple, reducing the manufacturing cost of the first fin 21. Along the width direction of the first fin 21, the widths of the multiple reinforcing ribs 2111 are different. The width of the reinforcing ribs 2111 can be designed according to the shape of the first fin 21 to better strengthen the strength of the edges of the first fin 21. Condensation water generated during the heat exchange process can drip along the first fin 21, making the first fin 21 easier to defrost. The width of the reinforcing ribs 2111 can be selected according to demand to meet different usage requirements.

[0065] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the first heat exchange tubes 22 are one row or multiple rows spaced apart along the width direction of the first fin 21, and each row includes multiple first heat exchange tubes 22 spaced apart along the length direction of the first fin 21. The number of rows of the first heat exchange tubes 22 can be selected according to parameters such as the power of the air conditioner 100 to meet different usage requirements.

[0066] like Figure 2 As shown, the reinforcing ribs 2111 extend along the first direction, and the angle A between the first direction and the arrangement direction of each row of first heat exchange tubes 22 is satisfied: -5°≤A≤10°. It can be understood that the angle A between the first direction and the arrangement direction of each row of first heat exchange tubes 22 can be -5°, -4.5°, -4°, -3.5°, -3°, -2.5°, -2°, -1.5°, -1°, -0.5°, 0°, 0.5°, 1°, 1.5°, 2°, 2.5°, 3°, 3.5°, 4°, 4.5°, 5°, 5.5°, 6°, 6.5°, 7°, 7.5°, 8°, 9°, 10°, 11°, 12°, 13°, 14°, 15°, 16°, 17°, 18°, 19°, 20°, 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28°, 29°, 30°, 31°, 32°, 33°, 34°, 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44°, 45°, 46°, 47°, 48°, 49°, 50°, 51°, 52°, 53°, 54°, 55°, 56°, 57°, 58°, 59°, 60°, 61°, 62°, 63°, 64°, 65°, 66°, .5°, 8°, 8.5°, 9°, 9.5° or 10°, the angle A between the first direction and the arrangement direction of each column of first heat exchange tubes 22 is not less than -5°, and the angle A between the first direction and the arrangement direction of each column of first heat exchange tubes 22 is not greater than 10°, so that there can be a certain angle between the first direction and the arrangement direction of each column of first heat exchange tubes 22, and the angle is not too large, thereby ensuring the reinforcement effect of the reinforcing rib 2111.

[0067] In some embodiments of the present invention, the reinforcing ribs 2111 extend along the first direction, and the angle between the first direction and the arrangement direction of each column of the first heat exchange tubes 22 is A and satisfies: -5°≤A≤10°, and multiple reinforcing ribs 2111 are spaced apart along the width direction of the first fin 21. The width direction of the first fin 21 is substantially perpendicular to the arrangement direction of each column of the first heat exchange tubes 22, and the length direction of the first fin 21 is substantially parallel to the arrangement direction of the first heat exchange tubes 22. In this embodiment, the reinforcing ribs 2111 extend along the first direction, and the angle between the first direction and the arrangement direction of each column of the first heat exchange tubes 22 is A and satisfies: -5°≤A≤10°, and multiple reinforcing ribs 2111 are spaced apart along the width direction of the first fin 21, so that the condensed water generated on the first heat exchange tubes 22 and the first fins 21 can flow to the overlap area 211 along the length direction of the first fin 21, and the condensed water can flow along the gap between the two adjacent reinforcing ribs 2111 to the bottom of the rear heat exchanger 2. As shown in FIG. Figure 5 As shown, the upper end of the reinforcing rib 2111 in the extension direction has a guide structure 21111; from top to bottom, the width and / or height of the guide structure 21111 gradually increases. The guide structure 21111 can guide condensed water.

[0068] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the first heat exchange tubes 22 are multiple rows spaced apart along the width direction of the first fin 21. The multiple rows of first heat exchange tubes 22 include a first row of heat exchange tubes 221 and a second row of heat exchange tubes 222 arranged in sequence from the windward side to the leeward side. Along the length direction of the first fin 21, the reinforcing ribs 2111 are arranged opposite to the second row of heat exchange tubes 222 on the leeward side. The reinforcing ribs 2111 can be arranged on the leeward side to enhance the heat exchange effect on the leeward side.

[0069] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, a bridge piece 2112 is provided between the first heat exchange tube 22 at the lowest end of the second row of heat exchange tubes 222 on the first fin 21 and the reinforcing rib 2111. The bridge piece 2112 is connected to the first fin 21 at both ends along the arrangement direction of the second row of heat exchange tubes 222, and the middle portion is spaced apart from the first fin 21. The bridge piece 2112 includes a top piece 21121 and a corresponding support piece 21122. The top piece 21121 extends perpendicularly to the first fin 21. 1 is hollowed out, and the location where the bridge fins 2112 are provided on the first fin 21 is hollowed out. The provision of the bridge fins 2112 disturbs the airflow as it passes between the lowest heat exchange tube of the second row of heat exchange tubes 222 and the reinforcing ribs 2111, changing the airflow's direction and enabling sufficient heat exchange with the first heat exchange tubes 22, further enhancing the heat exchange efficiency of the first fin 21. The greater the number of bridge fins 2112, the better the heat exchange efficiency of the first fin 21. Condensation generated during the heat exchange process is prone to dripping. The provision of the bridge fins 2112 can address the problem of frosting in the air conditioner 100, making it easier to defrost the first fin 21.

[0070] The number of bridge plates 2112 is 2-4. It is understood that the number of bridge plates 2112 can be 2, 3, or 4.

[0080] In some embodiments of the present invention, Figure 2 As shown, the diameter of the first heat exchange tube 22 is D1, and satisfies: 3.6 mm ≤ D ≤ 7.5 mm. It is understandable that the diameter D1 of the first heat exchange tube 22 may be 3.6 mm, 3.7 mm, 3.8 mm, 3.9 mm, 4 mm, 4.1 mm, 4.2 mm, 4.3 mm, 4.4 mm, 4.5 mm, 4.6 mm, 4.7 mm, 4.8 mm, 4.9 mm, 5 mm, 5.1 mm, 5.2 mm, 5.3 mm, 5.4 mm, 5.5 mm, 5.6 mm, 5.7 mm, 5.8 mm, 5.9 mm, 6 mm, 6.1 mm, 6.2 mm, 6.3 mm, 6.4 mm, 6.5 mm, 6.6 mm, 6.7 mm, 6.8 mm, 6.9 mm, 7 mm, 7.1 mm, 7.2 mm, 7.3 mm, 7.4 mm, or 7.5 mm.

The first bridge fin 2121 is connected to the first fin 21 at both ends along the arrangement direction of each row of first heat exchange tubes 22, and the middle part is separated from the first fin 21.

[0083] The first bridge fins 2121 include a first top sheet and a corresponding first support member. The portion perpendicular to the first fin 21 between the first top sheet and the first fin 21 is hollowed out, and the portion on the first fin 21 where the first bridge fins 21 are provided is also hollowed out. The first bridge fins 2121 are configured to disturb the airflow as it passes through the first airflow region 212, changing its direction and enabling sufficient heat exchange with the first heat exchange tubes 22, further enhancing the heat exchange efficiency of the first fins 21. The greater the number of first bridge fins 2121, the greater the heat exchange efficiency of the first fins 21. Condensation generated during the heat exchange process is easily dripped away. The provision of the first bridge fins 2121 can mitigate frost formation in the air conditioner 100, making the first fin 21 more convenient for defrosting.

[0084] The opening of the first louver is toward the windward side of the rear heat exchanger 2, or the opening of the first louver is toward the leeward side of the rear heat exchanger 2. The first louver has a better wind disturbing effect, and can better disturb the airflow when the airflow flows through the first heat exchange tube 22 at the lowest end of the second row of first heat exchange tubes 22 on the first fin 21 and the reinforcing rib 2111, thereby changing the flow direction of the airflow and enabling the airflow to fully exchange heat with the first heat exchange tube 22 on the rear heat exchanger 2, thereby further improving the heat exchange effect of the rear heat exchanger 2.

[0085] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the front heat exchanger 1 includes a plurality of second fins 11 spaced apart in the length direction of the front heat exchanger 1 and a second heat exchange tube 12 passing through the plurality of second fins 11. By providing a plurality of spaced apart second fins 11, the second heat exchange tube 12 can be fixed at a plurality of positions on the front heat exchanger 1, so that the position of the second heat exchange tube 12 on the front heat exchanger 1 can be more reliable, and the installation of the second heat exchange tube 12 can be more reliable.

[0086] The number of the second heat exchange tubes 12 is 22-28. It is understandable that the number of the second heat exchange tubes 12 can be 22, 23, 24, 25, 26, 27, or 28. The second heat exchange tubes 12 can be selectively arranged according to the heat exchange requirements and the area of ​​the area where the second heat exchange tubes 12 can be arranged to meet different usage requirements.

[0087] Furthermore, if Figure 1 and Figure 2As shown, the front heat exchanger 1 has multiple rows of second heat exchange tubes 12 arranged in sequence from the windward side to the leeward side, and the area between two adjacent second heat exchange tubes 12 in each row of second heat exchange tubes 12 on the second fin 11 is a second wind pass area 111. The second wind pass area 111 has a second bridge 1111 and / or a second louver. The second bridge 1111 is connected to the second fin 11 at both ends along the arrangement direction of each row of heat exchange tubes, and the middle part is separated from the second fin 11.

[0088] The second bridge fins 1111 include a second top sheet and a corresponding second support member. The portion between the second top sheet and the second fin 11, perpendicular to the second fin 11, is hollowed out, and the portion on the second fin 11 where the second bridge fins 111 are provided is also hollowed out. The provision of the second bridge fins 1111 disturbs the airflow as it passes through the second airflow region 111, changing its direction and enabling sufficient heat exchange with the second heat exchange tubes 12, further enhancing the heat exchange efficiency of the second fins 11. The greater the number of second bridge fins 1111, the better the heat exchange efficiency of the second fins 11. Condensation generated during the heat exchange process is easily dripped, and the provision of the second bridge fins 1111 can address the issue of frosting in the air conditioner 100, making the second fin 11 more convenient for defrosting.

[0089] The opening of the second louver is toward the windward side of the front heat exchanger 1, or the opening of the second louver is toward the leeward side of the front heat exchanger 1. The second louver has a better wind disturbing effect, and can better disturb the airflow when the airflow flows through the second heat exchange tube 12 at the lowest end of the second row of second heat exchange tubes 12 on the second fin 11 and the reinforcing rib 2111, thereby changing the flow direction of the airflow and enabling the airflow to fully exchange heat with the second heat exchange tube 12 on the front heat exchanger 1, thereby further improving the heat exchange effect of the front heat exchanger 1.

[0090] Furthermore, if Figure 1 As shown, the tube distance P1 between two adjacent second heat exchange tubes 12 in each row of the second heat exchange tubes 12 on the front heat exchanger 1 is the same, so that the layout of the second heat exchange tubes 12 on the front heat exchanger 1 is more uniform, so that the heat exchange effect of the front heat exchanger 1 is better and it is more convenient to assemble.

[0091] Furthermore, if Figure 2 As shown, the tube distance between two adjacent second heat exchange tubes 12 in each row of second heat exchange tubes 12 on the front heat exchanger 1 is P1 or P2. The second heat exchange tubes 12 can be set according to the heat exchange requirements of different positions of the front heat exchanger 1 to improve the heat exchange efficiency of the front heat exchanger 1.

[0092] Furthermore, if Figure 1As shown, the tube distance P3 between two adjacent second heat exchange tubes 12 in each row of first heat exchange tubes 22 on the rear heat exchanger 2 is the same, so that the layout of the first heat exchange tubes 22 on the rear heat exchanger 2 is more uniform, so that the heat exchange effect of the rear heat exchanger 2 is better and it is more convenient to assemble.

[0093] In some embodiments of the present invention, shutters are provided at the upper ends of the front heat exchanger 1 and the rear heat exchanger 2 . Driven by the impeller 20, the air flow outside the air conditioner 100 enters the interior of the shell 30 of the air conditioner 100 from the air inlet 301 located above the heat exchanger assembly 10, and the external air flow can directly flow to the upper ends of the front heat exchanger 1 and the rear heat exchanger 2. By providing shutters at the upper ends of the front heat exchanger 1 and the rear heat exchanger 2, the shutters can better block the air flow from flowing directly to the upper end of the connection area of ​​the front heat exchanger 1 and the rear heat exchanger 2, and can prevent the air flow from bypassing the first heat exchange tube 22 or the second heat exchange tube 12 at the upper ends of the front heat exchanger 1 and the rear heat exchanger 2 and directly flowing out of the air outlet 302 of the air conditioner 100 driven by the impeller 20, and can change the flow direction of the air flow so that the air flow can fully exchange heat with the first heat exchange tube 22 and the second heat exchange tube 12 on the front heat exchanger 1 and the rear heat exchanger 2, thereby further improving the heat exchange effect of the heat exchanger assembly 10.

[0094] The following describes a heat exchanger assembly 10 according to four specific embodiments of the present invention with reference to the accompanying drawings. It is worth noting that the following description is merely exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0095] Example 1

[0096] Specifically, the heat exchanger assembly 10 includes a front heat exchanger 1 and a rear heat exchanger 2 .

[0097] A heat exchanger can be used in an air conditioner 100, which includes a fan 20. For example, the air conditioner 100 is used indoors. The heat exchanger absorbs heat from the indoor air and transfers it to the outside, or transfers heat from the outside to the indoor, through a circulating refrigerant (such as Freon), thereby regulating the indoor temperature. The heat exchanger is a key device for heat transfer in the air conditioner 100. In cooling mode, the heat exchanger evaporates the refrigerant at low pressure, absorbing heat from the indoor air and lowering the indoor temperature. In heating mode, the refrigerant condenses at high temperature and high pressure through the condenser, releasing heat and transferring the heat to the indoor air, raising the indoor temperature.

[0098] The rear heat exchanger 2 is located at the rear side of the front heat exchanger 1 and its upper end is connected to the upper end of the front heat exchanger 1. The rear heat exchanger 2 includes a plurality of first fins 21 spaced apart in the length direction of the rear heat exchanger 2 and a first heat exchange tube 22 passing through the plurality of first fins 21. By providing a plurality of spaced apart first fins 21, the first heat exchange tube 22 can be fixed at a plurality of positions on the rear heat exchanger 2, so that the position of the first heat exchange tube 22 on the rear heat exchanger 2 can be more reliable, and the installation of the first heat exchange tube 22 can be more reliable.

[0099] The heat exchange medium flowing through the first heat exchange tube 22 transfers heat to the first fin 21, thereby increasing the heat exchange area of ​​the rear heat exchanger 2. The lower end of the first fin 21 has an overlapping region 211 with reinforcing ribs 2111 to strengthen the edge of the first fin 21. Condensation generated during the heat exchange process can drip along the overlapping region 211, thereby preventing frost on the air conditioner 100 and making the overlapping region 211 of the first fin 21 easier to defrost.

[0100] There are five spaced-apart reinforcing ribs 2111, which are arranged at intervals along the width direction of the first fin 21. Along the thickness direction of the first fin 21, the reinforcing ribs 2111 protrude from the first fin 21. Among the multiple reinforcing ribs 2111, there are at least two reinforcing ribs 2111 that protrude toward both sides of the thickness direction of the first fin 21, respectively, which can reduce the risk of deformation of the first fin 21 and increase the flatness of the first fin 21.

[0101] The multiple reinforcing ribs 2111 have the same height, and the ribs 2111 can be processed in a unified stamping process. This simplifies the manufacture of the ribs 2111, reducing the manufacturing cost of the first fin 21. Along the width direction of the first fin 21, the distance between any two adjacent reinforcing ribs 2111 is the same. During the processing of the reinforcing ribs 2111, the reinforcing ribs 2111 can be processed in a unified stamping process. This simplifies the manufacture of the ribs 2111, reducing the manufacturing cost of the first fin 21. Along the width direction of the first fin 21, the multiple reinforcing ribs 2111 have the same width, and the reinforcing ribs 2111 can be processed in a unified stamping process. This simplifies the manufacture of the ribs 2111, reducing the manufacturing cost of the first fin 21.

[0102] The first heat exchange tube 22 includes a first row of heat exchange tubes 221 and a second row of heat exchange tubes 222 arranged in sequence from the windward side to the leeward side. Along the length direction of the first fin 21, the reinforcing rib 2111 is arranged opposite to the second row of heat exchange tubes 222 on the leeward side. The reinforcing rib 2111 can be arranged on the leeward side to enhance the heat exchange effect on the leeward side.

[0103] The bridge piece 2112 is provided on the first fin 21 between the heat exchange tube at the lowest end of the second row of heat exchange tubes 222 and the reinforcing rib 2111. The bridge piece 2112 is connected to the first fin 21 at both ends along the arrangement direction of the second row of heat exchange tubes 222, and the middle part is separated from the first fin 21. The bridge piece 2112 includes a top piece 21121 and a corresponding support piece 21122. The position perpendicular to the first fin 21 between the top piece 21121 and the first fin 21 is hollowed out, and the position where the bridge piece 2112 is provided on the first fin 21 is hollowed out. By providing the bridge piece 2112, the airflow can be disturbed when it flows between the heat exchange tube at the lowest end of the second row of heat exchange tubes 222 and the reinforcing rib 2111, and the flow direction of the airflow can be changed, so that the airflow can fully exchange heat with the first heat exchange tube 22, further improving the heat exchange effect of the first fin 21. The more bridge pieces 2112 there are, the better the heat exchange effect of the first fin 21. At the same time, the condensed water produced during the heat exchange process is easy to drip, and the provision of the bridge piece 2112 can take into account the frost problem of the air conditioner 100, making it easier to defrost the first fin 21. The number of the bridge piece 2112 is four.

[0104] The rear heat exchanger 2 has multiple rows of first heat exchange tubes 22 arranged in sequence from the windward side to the leeward side. The area between two adjacent first heat exchange tubes 22 in each row of first heat exchange tubes 22 on the first fin 21 is a first wind pass area 212. The first wind pass area 212 has a first bridge fin 2121. The first bridge fin 2121 is connected to the first fin 21 at both ends along the arrangement direction of each row of first heat exchange tubes 22, and the middle part is separated from the first fin 21.

[0105] The first bridge fins 2121 include a first top sheet and a corresponding first support member. The portion perpendicular to the first fin 21 between the first top sheet and the first fin 21 is hollowed out, and the portion on the first fin 21 where the first bridge fins 21 are provided is also hollowed out. The first bridge fins 2121 are configured to disturb the airflow as it passes through the first airflow region 212, changing its direction and enabling sufficient heat exchange with the first heat exchange tubes 22, further enhancing the heat exchange efficiency of the first fins 21. The greater the number of first bridge fins 2121, the greater the heat exchange efficiency of the first fins 21. Condensation generated during the heat exchange process is easily dripped away. The provision of the first bridge fins 2121 can mitigate frost formation in the air conditioner 100, making the first fin 21 more convenient for defrosting.

[0106] The front heat exchanger 1 includes a plurality of second fins 11 spaced apart in the longitudinal direction of the front heat exchanger 1 and a second heat exchange tube 12 passing through the plurality of second fins 11. By providing a plurality of spaced apart second fins 11, the second heat exchange tube 12 can be fixed at a plurality of positions on the front heat exchanger 1, so that the position of the second heat exchange tube 12 on the front heat exchanger 1 can be more reliable, and the installation of the second heat exchange tube 12 can be more reliable.

[0107] The front heat exchanger 1 has multiple rows of second heat exchange tubes 12 arranged in sequence from the windward side to the leeward side. The area between two adjacent second heat exchange tubes 12 in each row of second heat exchange tubes 12 on the second fin 11 is a second wind pass area 111. The second wind pass area 111 has a second bridge fin 1111. The second bridge fin 1111 is connected to the second fin 11 at both ends along the arrangement direction of each row of heat exchange tubes, and the middle part is separated from the second fin 11.

[0108] The second bridge fins 1111 include a second top sheet and a corresponding second support member. The portion between the second top sheet and the second fin 11, perpendicular to the second fin 11, is hollowed out, and the portion on the second fin 11 where the second bridge fins 111 are provided is also hollowed out. The provision of the second bridge fins 1111 disturbs the airflow as it passes through the second airflow region 111, changing its direction and enabling sufficient heat exchange with the second heat exchange tubes 12, further enhancing the heat exchange efficiency of the second fins 11. The greater the number of second bridge fins 1111, the better the heat exchange efficiency of the second fins 11. Condensation generated during the heat exchange process is easily dripped, and the provision of the second bridge fins 1111 can address the issue of frosting in the air conditioner 100, making the second fin 11 more convenient for defrosting.

[0109] The tube spacing P1 between adjacent second heat exchange tubes 12 in each row of the front heat exchanger 1 is the same, resulting in a more uniform layout of the second heat exchange tubes 12 on the front heat exchanger 1, improving the heat exchange effect of the front heat exchanger 1 and making assembly more convenient. The tube spacing P3 between adjacent second heat exchange tubes 12 in each row of the rear heat exchanger 2 is the same, resulting in a more uniform layout of the first heat exchange tubes 22 on the rear heat exchanger 2, improving the heat exchange effect and making assembly more convenient.

[0110] Shutters are provided at the upper ends of the front heat exchanger 1 and the rear heat exchanger 2. Driven by the impeller 20, airflow outside the air conditioner 100 enters the interior of the housing 30 of the air conditioner 100 from the air inlet 301 located above the heat exchanger assembly 10. The external airflow can flow directly to the upper ends of the front heat exchanger 1 and the rear heat exchanger 2. By providing louvers at the upper ends of the front heat exchanger 1 and the rear heat exchanger 2, the louvers can effectively prevent the airflow from flowing directly to the upper end of the connection area between the front heat exchanger 1 and the rear heat exchanger 2. This can prevent the airflow from bypassing the first heat exchange tube 22 or the second heat exchange tube 12 at the upper ends of the front heat exchanger 1 and the rear heat exchanger 2 and flowing directly out of the air outlet 302 of the air conditioner 100 driven by the impeller 20. This can change the flow direction of the airflow, allowing the airflow to fully exchange heat with the first heat exchange tube 22 and the second heat exchange tube 12 on the front heat exchanger 1 and the rear heat exchanger 2, further improving the heat exchange effect of the heat exchanger assembly 10.

[0111] Example 2

[0112] The structure of this embodiment is roughly the same as that of the first embodiment, wherein the same components are marked with the same reference numerals. The only difference is that the tube spacing between two adjacent second heat exchange tubes 12 in each row of second heat exchange tubes 12 on the front heat exchanger 1 is P1 or P2. The second heat exchange tubes 12 can be arranged according to the heat exchange requirements of different positions of the front heat exchanger 1 to improve the heat exchange efficiency of the front heat exchanger 1.

[0113] Example 3

[0114] The structure of this embodiment is substantially the same as that of the first embodiment, with identical components designated by the same reference numerals. The only difference lies in a louver structure 2113 disposed between the bottommost heat exchange tube in the second row of heat exchange tubes 222 on the first fin 21 and the reinforcing rib 2111.

The heat exchange effect of the heat exchanger assembly 10 is better.

[0119] According to the air conditioner 100 of the present invention, by inserting the first heat exchange tubes 22 through a plurality of first fins 21 spaced apart along the length of the rear heat exchanger 2, the heat exchange medium flowing in the first heat exchange tubes 22 can transfer heat to the first fins 21, thereby increasing the heat exchange area of ​​the rear heat exchanger 2.

If the dimension L3 of the air conditioner 100 along the front-to-back direction is not less than 190 mm, there is sufficient space inside the air conditioner 100 to install the impeller 20 and the heat exchanger assembly 10. If the dimension L3 of the air conditioner 100 along the front-to-back direction is not greater than 230 mm, the thickness of the air conditioner 100 is relatively reasonable, and the space occupied during transportation is small, which can improve the transportation efficiency of the air conditioner 100.

[0122] In some embodiments of the present invention, Figure 2As shown, the housing 30 includes a support base 303, and the overlapping region 211 is supported on the support base 303. Reinforcing ribs 2111 are provided at positions corresponding to the overlapping region 211 and the support base 303.
