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

[0056] A heat exchanger assembly 10 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0057] like Figure 1 As shown, the heat exchanger assembly 10 according to an embodiment of the present invention includes a rear heat exchanger 2 and a front heat exchanger 1 .

[0058] Specifically, the heat exchanger assembly 10 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 assembly 10 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 assembly 10 is a key device for heat transfer in the air conditioner 100. In cooling mode, the heat exchanger assembly 10 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.

[0059] like Figure 1 and Figure 2As shown, the front heat exchanger 1 is located in front of the rear heat exchanger 2 and its upper end is connected to the upper end of the rear heat exchanger 2. The front heat exchanger 1 includes a plurality of front heat exchange fins 11 spaced apart in the length direction of the heat exchanger assembly 10 and a front heat exchange tube 12 passing through the plurality of front heat exchange fins 11. By providing a plurality of spaced apart front heat exchange fins 11, the front heat exchange tube 12 can be fixed at a plurality of positions on the front heat exchanger 1, so that the position of the front heat exchange tube 12 on the front heat exchanger 1 can be more reliable, and the installation of the front heat exchange tube 12 can be more reliable.

[0060] Among them, the length direction of the front heat exchanger 1 is Figure 1 The up-down direction and the front-back direction are both perpendicular. The front heat exchange tube 12 includes a straight tube section and connecting tubes connected to both ends of the straight tube section. The connecting tube is used to connect two adjacent front heat exchange tubes 12 or the inlet and outlet pipes of the heat exchanger assembly 10. The connecting tube can be a U-shaped tube or a half U-shaped tube.

[0061] The heat exchange medium flowing in the front heat exchange tube 12 can transfer heat to the front heat exchange fins 11, thereby increasing the heat exchange area of ​​the front heat exchanger 1. For example, in cooling mode, refrigerant flows in the front heat exchange tube 12, and the cooling capacity of the refrigerant can be dissipated to the front heat exchange fins 11 through the front heat exchange tube 12. External air enters the air conditioner 100, flows to the front heat exchanger 1, and exchanges heat with the refrigerant in the front heat exchange tube 12. The refrigerant in the front heat exchange tube 12 evaporates and absorbs heat. At the same time, the airflow can also exchange heat with the front heat exchange fins 11. The airflow gradually cools and flows out from the air outlet 302 driven by the wind wheel 20.

[0062] The front heat exchange tubes 12 are arranged in a plurality of rows spaced apart in the width direction of the front heat exchange fins 11. Figure 1 As shown, the multiple rows of front heat exchange tubes 12 include multiple front heat exchange tubes 121 located in a row on the windward side and multiple rear heat exchange tubes 122 located in a row on the leeward side. The tube spacing of the multiple front heat exchange tubes 121 includes a first tube spacing and a second tube spacing, and the first tube spacing is smaller than the second tube spacing. It can be understood that by setting the first tube spacing and the second tube spacing at different distances, the positions of the front heat exchange tubes 121 can be arranged more flexibly, and the front heat exchange tubes 121 can be arranged as much as possible in positions with good heat exchange with the airflow. When the external airflow enters the air conditioner 100, the airflow flows into the front heat exchanger 1, and the airflow flows through the front heat exchange tubes 121, achieving a good heat exchange effect with the front heat exchange tubes 121. This ensures that the airflow can exchange heat with the front heat exchange tubes 121 as much as possible, thereby better achieving the heat exchange effect of the front heat exchanger 1 and the heat exchanger assembly 10.

[0063] According to the heat exchanger assembly 10 of the embodiment of the present invention, by setting the tube spacing of multiple front row heat exchange tubes 121 located in a row on the windward side among the multiple rows of front heat exchange tubes 12 to a first tube spacing and a second tube spacing with different distances, the positions of the front row heat exchange tubes 121 can be arranged more flexibly, and the front row heat exchange tubes 121 can be arranged as much as possible in positions where heat exchange with the airflow is better. The external airflow enters the air conditioner 100, and the airflow flows to the front heat exchanger 1. The airflow flows through the front row heat exchange tubes 121, and the heat exchange effect with the front row heat exchange tubes 121 is better, ensuring that the airflow can exchange heat with the front row heat exchange tubes 121 as much as possible, which can better achieve the heat exchange effect of the front heat exchanger 1 and the heat exchange effect of the heat exchanger assembly 10.

[0064] In some embodiments of the present invention, Figure 1 As shown, the tube spacing of the plurality of rear-row heat exchange tubes 122 is the third tube spacing, which is equal to the first tube spacing. This allows the front-row heat exchange tubes 121 to be spaced as far apart from the rear-row heat exchange tubes 122 as possible. At least one front-row heat exchange tube 121 is provided between two adjacent rear-row heat exchange tubes 122, and at least one rear-row heat exchange tube 122 is provided between two adjacent front-row heat exchange tubes 121. When external airflow enters the air conditioner 100, it flows to the front heat exchanger 1. After flowing between two adjacent front-row heat exchange tubes 121, the airflow can flow to the at least one rear-row heat exchange tube 122, ensuring that the airflow can exchange heat with the front heat exchange tubes 12 as much as possible, thereby better achieving the heat exchange effect of the front heat exchanger 1 and the heat exchanger assembly 10.

[0065] In some embodiments of the present invention, Figure 1As shown, the front heat exchanger 1 includes a first heat exchange part 13, a second heat exchange part 14 and a third heat exchange part 15 which are connected in sequence along the extension direction of the front heat exchanger 1. The first heat exchange part 13 and the third heat exchange part 15 are respectively located at the two ends of the extension direction of the front heat exchanger 1, and the second heat exchange part 14 is located between the first heat exchange part 13 and the third heat exchange part 15. The tube spacing of the multiple front row heat exchange tubes 121 in the first heat exchange part 13 and the third heat exchange part 15 is both the first tube spacing, and the tube spacing of the multiple front row heat exchange tubes 121 in the second heat exchange part 14 includes the second tube spacing. It can be understood that the second heat exchange portion 14 connects the first heat exchange portion 13 and the third heat exchange portion 15, and in order to adapt to the housing 30 of the air conditioner 100, the second heat exchange portion 14 is tilted or arc-shaped. When the tube spacing of the front row heat exchange tubes 121 located in the second heat exchange portion 14 is the second tube spacing, it is greater than the tube spacing of the front row heat exchange tubes 121 in the first heat exchange portion 13 and the third heat exchange portion 15, thereby avoiding an increase in the number of the front row heat exchange tubes 121 arranged at the second heat exchange portion 14 and trying to achieve a spacing between two adjacent rear row heat exchange tubes 122. At least one front row heat exchange tube 121 is correspondingly provided between two adjacent front row heat exchange tubes 121, and at least one rear row heat exchange tube 122 is correspondingly provided between two adjacent front row heat exchange tubes 121. The external airflow enters the air conditioner 100, and the airflow flows to the front heat exchanger 1. After the airflow flows between two adjacent ones of the front row heat exchange tubes 121, it can flow to at least one rear row heat exchange tube 122, ensuring that the airflow can exchange heat with the front heat exchange tubes 12 as much as possible, which can better achieve the heat exchange effect of the front heat exchanger 1 and the heat exchange effect of the heat exchanger assembly 10.

[0066] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the area between two adjacent front heat exchange tubes 12 in each row of front heat exchange tubes 12 is a wind-passing area 111, and a wind-passing structure 112 is provided on the wind-passing area 111. The wind-passing structure 112 can disturb the airflow when the airflow flows through the wind-passing area 111, and can change the flow direction of the airflow, so that the airflow can fully exchange heat with the front heat exchange tubes 12, further improving the heat exchange effect of the front heat exchange fins 11.

[0067] Furthermore, if Figure 1 and Figure 2As shown, the air flow structures 112 between the front heat exchange tubes 12 in a row on the leeward side are all bridge structures 113. The bridge structures 113 are connected to the front heat exchange fins 11 at both ends along the arrangement direction of the front heat exchange tubes 12 in a row on the leeward side, and the middle part is separated from the front heat exchange fins 11. The bridge structure 113 includes a top plate structure and a corresponding support structure. The position between the top plate structure and the front heat exchange fins 11 that is perpendicular to the front heat exchange fins 11 is hollowed out, and the position where the bridge structure 113 is set on the front heat exchange fins 11 is hollowed out. By setting the bridge structure 113, the airflow can be disturbed when flowing between the front heat exchange tubes 12 in a row on the leeward side, and the flow direction of the airflow can be changed, so that the airflow can fully exchange heat with the front heat exchange tubes 12, further improving the heat exchange effect of the front heat exchange fins 11, and the more bridge structures 113 there are, the better the heat exchange effect of the front heat exchange fins 11. The number of bridge fins in the bridge fin structure 113 is 2-3. It is understood that the number of bridge fins in the bridge fin structure 113 can be 2 or 3. The bridge fin structure 113 can be selectively arranged according to the heat exchange requirements and the area where the bridge fin structure 113 can be arranged to meet different usage requirements.

[0068] In some embodiments of the present invention, the airflow structure 112 located between the front heat exchange tubes 12 in a row on the leeward side includes a bridge structure 113 and louvers, and the number of bridges in the bridge structure 113 is 2-3. The bridge structure 113 includes a top plate structure and a corresponding support structure. The position perpendicular to the front heat exchange fins 11 between the top plate structure and the front heat exchange fins 11 is hollowed out, and the position where the bridge structure 113 is set on the front heat exchange fins 11 is hollowed out. By setting the bridge structure 113, the airflow can be disturbed when it flows between the front heat exchange tubes 12 in a row on the leeward side, changing the flow direction of the airflow, so that the airflow can fully exchange heat with the front heat exchange tubes 12, further improving the heat exchange effect of the front heat exchange fins 11, and the more bridge structures 113 there are, the better the heat exchange effect of the front heat exchange fins 11.

[0069] The opening of the louver is toward the windward side of the front heat exchanger 1, or the opening of the louver is toward the leeward side of the front heat exchanger 1. The louver has a better wind disturbing effect, which can better disturb the airflow when it flows between the front heat exchange tubes 12 in a row on the leeward side, change the flow direction of the airflow, and enable the airflow to fully exchange heat with the front heat exchange tubes 12, further improving the heat exchange effect of the front heat exchange fins 11.

[0070] The number of bridge fins in the bridge fin structure 113 may be 2 or 3. The bridge fin structure 113 may be selectively arranged according to heat exchange requirements and the area of ​​the region where the bridge fin structure 113 can be arranged to meet different usage requirements.

[0071] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the front heat exchange tubes 12 located in a row on the windward side are S1, S2, S3, S4, S5, S6, S7 and S8 in the direction from bottom to top, and the distances between S1 and S2, S2 and S3, S3 and S4, S5 and S6 and S7 and S8 are all Q1, and the distances between S4 and S5 and S6 and S7 are Q2, and Q2>Q1 is satisfied. By adjusting the distance between two adjacent front heat exchange tubes 12 at the lower ends of the front heat exchange tubes 12 in a row on the windward side, it can be ensured that the front heat exchange tubes 12 in the row on the windward side are staggered with at least one other row of front heat exchange tubes 12. The external airflow enters the air conditioner 100, and the airflow flows to the front heat exchanger 1. After the airflow flows between two adjacent front heat exchange tubes 12 in the row on the windward side, it can flow to at least one front heat exchange tube 12 in another row of front heat exchange tubes 12, ensuring that the airflow can exchange heat with the front heat exchange tubes 12 as much as possible, which can better achieve the heat exchange effect of the front heat exchanger 1 and the heat exchange effect of the heat exchanger assembly 10.

[0072] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, a bridge structure 113 is provided between the front heat exchange tubes 12 located in a row on the leeward side, the bridge structure 113 between S1 and S2 is exactly the same as the bridge structure 113 between S5 and S6 and is X1, the bridge structure 113 between S6 and S7 is exactly the same as the bridge structure 113 between S4 and S5 and is X2, the bridge structure 113 between S2 and S3, the bridge structure 113 between S3 and S4, and the bridge structure 113 between S7 and S8 are exactly the same and are X3, wherein, along the length direction of the front heat exchange fin 11, the length of X3 is less than X2, and the number of bridges in the bridge structure 113 of X1 is less than X3. By adjusting the length and number of the bridge structure 113 at the lower end of the front heat exchange tube 12 in the row on the windward side, it can be ensured that the front heat exchange tube 12 in the row on the windward side is staggered with at least one other row of front heat exchange tubes 12. The external airflow enters the air conditioner 100, and the airflow flows to the front heat exchanger 1. After the airflow flows between two adjacent front heat exchange tubes 12 in the row on the windward side, it can flow to at least one front heat exchange tube 12 in another row of front heat exchange tubes 12, ensuring that the airflow can exchange heat with the front heat exchange tubes 12 as much as possible, which can better achieve the heat exchange effect of the front heat exchanger 1 and the heat exchange effect of the heat exchanger assembly 10.

[0073] In some embodiments of the present invention, Figure 1 and Figure 2As shown, the airflow structure 112 between the front row heat exchange tubes 121 includes second bridge pieces 1111 and / or second louvers. The second bridge pieces 1111 are connected to the front heat exchange fins 11 at both ends along the arrangement direction of the front row heat exchange tubes 121, and are separated from the front heat exchange fins 11 in the middle.

[0074] The second bridge fins 1111 include a second top sheet 21121 and a corresponding second support member 21122. The area between the second top sheet 21121 and the front heat exchange fins 11, perpendicular to the front heat exchange fins 11, is hollowed out, and the area on the front heat exchange fins 11 where the second bridge fins 1111 are provided is also hollowed out. The provision of the second bridge fins 1111 disturbs the airflow as it passes through the windward region 111, changing its direction and enabling sufficient heat exchange with the front heat exchange tubes 12, further enhancing the heat exchange efficiency of the front heat exchange fins 11. The greater the number of second bridge fins 1111, the better the heat exchange efficiency of the front heat exchange fins 11. Condensation generated during the heat exchange process is prone to dripping. The provision of the second bridge fins 1111 can address the issue of frosting in the air conditioner 100, making the front heat exchange fins 11 more convenient for defrosting.

[0075] 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 front heat exchange fin 11 between the front heat exchange tube 12 at the lowest end of the second row of front heat exchange tubes 12 and the reinforcing rib 2111, thereby changing the flow direction of the airflow and enabling the airflow to fully exchange heat with the front heat exchange tube 12 on the front heat exchanger 1, thereby further improving the heat exchange effect of the front heat exchanger 1.

[0076] In some embodiments of the present invention, Figure 1 As shown, the rear heat exchanger 2 includes a plurality of rear heat exchange fins 21 spaced apart in the length direction of the rear heat exchanger 2 and a rear heat exchange tube 22 passing through the plurality of rear heat exchange fins 21. By providing a plurality of spaced apart rear heat exchange fins 21, the rear heat exchange tube 22 can be fixed at a plurality of positions on the rear heat exchanger 2, so that the position of the rear heat exchange tube 22 on the rear heat exchanger 2 can be more reliable, and the installation of the rear heat exchange tube 22 can be more reliable.

[0077] Among them, the length direction of the rear heat exchanger 2 is the same as that of the attached Figure 1 The vertical direction and the front-to-back direction are both perpendicular. The rear heat exchange tube 22 includes a straight tube section and connecting tubes connected at both ends of the straight tube section. The connecting tube is used to connect two adjacent rear heat exchange tubes 22 or the inlet and outlet pipes of the heat exchanger assembly 10. The connecting tube can be a U-shaped tube or a half U-shaped tube.

[0078] The heat exchange medium flowing in the rear heat exchange tubes 22 can transfer heat to the rear heat exchange fins 21, thereby increasing the heat exchange area of ​​the rear heat exchanger 2. For example, in cooling mode, refrigerant flows in the rear heat exchange tubes 22, and the cooling capacity of the refrigerant can be dissipated to the rear heat exchange fins 21 through the rear heat exchange tubes 22. External air enters the air conditioner 100, flows toward the rear heat exchanger 2, and exchanges heat with the refrigerant in the rear heat exchange tubes 22. The refrigerant in the rear heat exchange tubes 22 evaporates and absorbs heat. At the same time, the airflow can also exchange heat with the rear heat exchange fins 21. The airflow gradually cools and flows out of the air outlet 302 driven by the wind wheel 20.

[0079] The lower end of the rear heat exchange fin 21 has an overlapping area 211 for supporting on the shell 30 of the air conditioner 100. The overlapping area 211 is provided with reinforcing ribs 2111, which can enhance the strength of the edge of the rear heat exchange 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 rear heat exchange fin 21 easier to defrost.

[0080] Furthermore, if Figure 1 As shown, there are multiple reinforcing ribs 2111 spaced apart, and multiple reinforcing ribs 2111 can improve the strength of the rear heat exchange fin 21 in multiple places. The reinforcing effect of the reinforcing ribs 2111 is better. Multiple reinforcing ribs 2111 are arranged at intervals along the width direction of the rear heat exchange fin 21. Along the thickness direction of the rear heat exchange fin 21, the reinforcing ribs 2111 protrude from the rear heat exchange fin 21, which can increase the cross-sectional area of ​​the rear heat exchange fin 21 and significantly improve the strength and rigidity of the rear heat exchange fin 21.

[0081] Furthermore, if Figure 1 、 Figure 6 and Figure 7 As shown, along the thickness direction of the rear heat exchange fin 21, multiple reinforcing ribs 2111 protrude toward the same side, making the processing and manufacturing of the reinforcing ribs 2111 relatively convenient. Alternatively, at least two of the multiple reinforcing ribs 2111 protrude toward both sides of the thickness direction of the rear heat exchange fin 21, respectively. This can reduce the risk of deformation of the rear heat exchange fin 21 and improve the flatness of the rear heat exchange fin 21.

[0082] 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 rear heat exchange fins 21. The number of reinforcing ribs 2111 is no more than 8 to avoid overly complex manufacturing of the rear heat exchange fins 21, thereby reducing the manufacturing cost of the rear heat exchange fins 21.

[0083] In some embodiments of the present invention, the heights of the multiple reinforcing ribs 2111 are the same or different. It is understood that the heights of the multiple reinforcing ribs 2111 are the same, and the reinforcing ribs 2111 can be processed uniformly through stamping and other steps. This simplifies the manufacture of the reinforcing ribs 2111 and reduces the manufacturing cost of the rear heat exchange fins 21. The heights of the multiple reinforcing ribs 2111 can be designed based on the shape of the rear heat exchange fins 21, thereby further strengthening the strength of the edges of the rear heat exchange fins 21. Condensation generated during the heat exchange process can drip along the rear heat exchange fins 21, making the rear heat exchange fins 21 easier to defrost. The heights of the multiple reinforcing ribs 2111 can be selected as needed to meet different usage requirements.

[0084] In some embodiments of the present invention, along the width direction of the rear heat exchange 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 can be the same or different. It is understood that along the width direction of the rear heat exchange fin 21, the distance between any two adjacent reinforcing ribs 2111 among the multiple reinforcing ribs 2111 is the same. The reinforcing ribs 2111 can be processed through a unified stamping process, simplifying the manufacture of the reinforcing ribs 2111 and reducing the manufacturing cost of the rear heat exchange fin 21. Along the width direction of the rear heat exchange fin 21, the distance between any two adjacent reinforcing ribs 2111 among the multiple reinforcing ribs 2111 can be different. The distance between any two adjacent reinforcing ribs 2111 can be designed based on the shape of the rear heat exchange fin 21 to better strengthen the edge strength of the rear heat exchange fin 21. Condensation generated during the heat exchange process can drip along the rear heat exchange fin 21, making the rear heat exchange fin 21 easier to defrost. The distance between any two adjacent reinforcing ribs 2111 can be selected based on manufacturing needs to meet different usage requirements.

[0085] In some embodiments of the present invention, Figure 6 and Figure 7 As shown, along the width direction of the rear heat exchange fin 21, the widths of the multiple reinforcing ribs 2111 are the same or different. It is understood that along the width direction of the rear heat exchange 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. This simplifies the manufacture of the reinforcing ribs 2111, reducing the manufacturing cost of the rear heat exchange fin 21. Along the width direction of the rear heat exchange fin 21, the widths of the multiple reinforcing ribs 2111 vary. The widths of the reinforcing ribs 2111 can be designed based on the shape of the rear heat exchange fin 21 to better strengthen the strength of the edges of the rear heat exchange fin 21. Condensation generated during the heat exchange process can drip along the rear heat exchange fin 21, making it easier to defrost the rear heat exchange fin 21. The width of the reinforcing ribs 2111 can be selected as needed to meet different usage requirements.

[0086] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the rear heat exchange tubes 22 are one row or multiple rows spaced apart along the width direction of the rear heat exchange fins 21. Each row includes multiple rear heat exchange tubes 22 spaced apart along the length direction of the rear heat exchange fins 21. The number of rows of the rear heat exchange tubes 22 can be selected according to parameters such as the power of the air conditioner 100 to meet different usage requirements.

[0087] like Figure 2 As shown, the reinforcing ribs 2111 extend along a first direction, and the angle A between the first direction and the arrangement direction of each row of rear heat exchange tubes 22 is satisfied: -5°≤A≤10°. It is understandable that the angle A between the first direction and the arrangement direction of each row of rear 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 row of rear heat exchange tubes 22 is not less than -5°, and the angle A between the first direction and the arrangement direction of each row of rear 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 row of rear heat exchange tubes 22, and the angle is not too large, thereby ensuring the strengthening effect of the reinforcing rib 2111.

[0088] Among them, the width direction of the rear heat exchange fin 21 is substantially perpendicular to the arrangement direction of each row of rear heat exchange tubes 22, and the length direction of the rear heat exchange fin 21 is substantially parallel to the arrangement direction of the rear heat exchange tubes 22. In this embodiment, the reinforcing rib 2111 extends along the first direction, and the angle between the first direction and the arrangement direction of each row of rear heat exchange tubes 22 is A and satisfies: -5°≤A≤10°. Multiple reinforcing ribs 2111 are arranged at intervals along the width direction of the rear heat exchange fin 21, so that the condensed water generated on the rear heat exchange tubes 22 and the rear heat exchange fin 21 can flow to the overlap area 211 along the length direction of the rear heat exchange fin 21, and the condensed water can flow to the bottom of the rear heat exchanger 2 along the gap between two adjacent reinforcing ribs 2111. 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.

[0089] In some embodiments of the present invention, Figure 1 and Figure 2As shown, the rear heat exchange tubes 22 are multiple rows spaced apart along the width direction of the rear heat exchange fins 21. The multiple rows of rear 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 rear heat exchange fins 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.

[0090] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, a bridge piece 2112 is provided between the rear heat exchange tube 22 at the lowest end of the second row of heat exchange tubes 222 on the rear heat exchange fin 21 and the reinforcing rib 2111. The bridge piece 2112 is connected to the rear heat exchange 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 rear heat exchange 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 rear heat exchange fin 21. The location of the rear heat exchange fins 21 is hollowed out, and the location where the bridge fins 2112 are provided on the rear heat exchange fins 21 is hollowed out. The provision of the bridge fins 2112 disturbs the airflow as it passes between the bottommost 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 rear heat exchange tubes 22. This further enhances the heat exchange efficiency of the rear heat exchange fins 21. The greater the number of bridge fins 2112, the better the heat exchange efficiency of the rear heat exchange fins 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 rear heat exchange fins 21.

[0091] 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. The bridge plates 2112 can be selectively arranged according to the heat exchange requirements and the area of ​​the area where the bridge plates 2112 can be arranged to meet different usage requirements.

[0092] In some embodiments of the present invention, Figure 1 and Figure 3As shown, along the arrangement direction of the second row of heat exchange tubes 222, the length of the bridge fins 2112 is L1 and satisfies the following relationship: 0.8 mm ≤ L1 ≤ 1.4 mm. It is understood that along the arrangement direction of the second row of heat exchange tubes 222, the length L1 of the bridge fins 2112 can be 0.8 mm, 0.85 mm, 0.9 mm, 0.95 mm, 1 mm, 1.05 mm, 1.1 mm, 1.15 mm, 1.2 mm, 1.25 mm, 1.3 mm, 1.35 mm, or 1.4 mm. Along the arrangement direction of the second row of heat exchange tubes 222, the length L1 of the bridge piece 2112 is not less than 0.8 mm, which can ensure the size of the bridge piece 2112 and the heat exchange effect of the rear heat exchange fin 21; along the arrangement direction of the second row of heat exchange tubes 222, the length L1 of the bridge piece 2112 is not greater than 1.4 mm, which can avoid the size of the bridge piece 2112 being too large and avoid affecting the strength of the rear heat exchange fin 21.

[0093] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, along the thickness direction of the rear heat exchange fin 21, the height of the bridge fin 2112 is H1 and satisfies: 0.6mm≤H1≤0.9mm. It is understandable that along the thickness direction of the rear heat exchange fin 21, the height H1 of the bridge fin 2112 can be 0.6mm, 0.65mm, 0.7mm, 0.75mm, 0.8mm, 0.85mm or 0.8mm. Along the thickness direction of the rear heat exchange fin 21, the height H1 of the bridge fin 2112 is not less than 0.6mm, which can ensure the size of the bridge fin 2112 and the heat exchange effect of the rear heat exchange fin 21; along the thickness direction of the rear heat exchange fin 21, the height H1 of the bridge fin 2112 is not greater than 0.9mm, which can avoid the bridge fin 2112 being too large and thus avoiding affecting the strength of the rear heat exchange fin 21.

[0094] In some embodiments of the present invention, Figure 4 As shown, a louver structure 2113 is provided between the rear heat exchange tube 22 at the lowest end of the second row of heat exchange tubes 222 on the rear heat exchange fin 21 and the reinforcing rib 2111. The opening of the louver structure 2113 faces the windward side of the rear heat exchanger 2, or the opening of the louver structure 2113 faces the leeward side of the rear heat exchanger 2. The louver structure 2113 has a better wind disturbing effect, and can better disturb the airflow when the airflow flows through between the heat exchange tube at the lowest end of the second row of heat exchange tubes 222 on the rear heat exchange 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 rear heat exchange tube 22 on the rear heat exchanger 2, thereby further improving the heat exchange effect of the rear heat exchanger 2.

[0095] The number of louver structures 2113 is 2-4. It is understood that the number of louver structures 2113 can be 2, 3, or 4. Louver structures 2113 can be selectively installed based on heat exchange requirements and the area of ​​the area where the louver structures 2113 can be installed to meet different usage requirements.

[0096] In some embodiments of the present invention, Figure 4 As shown, along the arrangement direction of the second row of heat exchange tubes 222, the length of the louver structure 2113 is L2 and satisfies the following relationship: 1.2 mm ≤ L2 ≤ 1.8 mm. It is understood that along the arrangement direction of the second row of heat exchange tubes 222, the length L2 of the louver structure 2113 can be 1.2 mm, 1.25 mm, 1.3 mm, 1.35 mm, 1.4 mm, 1.45 mm, 1.5 mm, 1.55 mm, 1.6 mm, 1.65 mm, 1.7 mm, 1.75 mm, or 1.8 mm. Along the arrangement direction of the second row of heat exchange tubes 222, the length L2 of the louver structure 2113 is not less than 1.2 mm, which can ensure the size of the louver structure 2113 and the heat exchange effect of the rear heat exchange fins 21; along the arrangement direction of the second row of heat exchange tubes 222, the length L2 of the louver structure 2113 is not greater than 1.8 mm, which can avoid the size of the louver structure 2113 being too large and avoid affecting the strength of the rear heat exchange fins 21.

[0097] In some embodiments of the present invention, Figure 4 As shown, along the thickness direction of the rear heat exchange fin 21, the height of the louver structure 2113 is H2 and satisfies the following conditions: 0.6mm≤H2≤0.8mm. It is understood that along the thickness direction of the rear heat exchange fin 21, the height H2 of the louver structure 2113 can be 0.6mm, 0.65mm, 0.7mm, 0.75mm, 0.8mm, 0.85mm, or 0.8mm. Along the thickness direction of the rear heat exchange fin 21, the height H2 of the louver structure 2113 is not less than 0.6mm, which ensures the size of the louver structure 2113 and the heat exchange effect of the rear heat exchange fin 21. Along the thickness direction of the rear heat exchange fin 21, the height H2 of the louver structure 2113 is not greater than 0.9mm, which prevents the louver structure 2113 from being too large and thus affecting the strength of the rear heat exchange fin 21.

[0098] 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 rear heat exchange fin 21) and the adjacent rear heat exchange tube 22 is greater than the distance between two adjacent rear heat exchange tubes 22. The adjacent rear heat exchange tube 22 refers to the rear 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 rear 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 rear heat exchange tube 22. The distance between two adjacent rear heat exchange tubes 22 can be the distance between the central axes of the straight sections of two connected rear heat exchange tubes 22, or the distance between the central axes of the straight sections of the two closest rear heat exchange tubes 22. The distance between the lower end of the overlapping region 211 and the adjacent rear heat exchange tube 22 is greater than the distance between two adjacent rear heat exchange tubes 22, thereby facilitating the support of the rear heat exchanger 2 on the housing 30 of the air conditioner 100 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 .

[0099] Furthermore, if Figure 1 As shown, the tube distance P1 between two adjacent front heat exchange tubes 12 in each row of front heat exchange tubes 12 on the front heat exchanger 1 is the same, so that the layout of the front 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.

[0100] Furthermore, if Figure 2 As shown, the tube distance between two adjacent front heat exchange tubes 12 in each row of front heat exchange tubes 12 on the front heat exchanger 1 is P1 or P2. The front 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.

[0101] Furthermore, if Figure 1 As shown, the tube distance P3 between two adjacent front heat exchange tubes 12 in each row of rear heat exchange tubes 22 on the rear heat exchanger 2 is the same, so that the layout of the rear 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.

[0102] In some embodiments of the present invention, Figure 2As shown, the width M of the rear heat exchange fin 21 satisfies the following conditions: 25 mm ≤ M ≤ 28 mm. It is understood that the width M of the rear heat exchange fin 21 can be 25 mm, 25.5 mm, 26 mm, 26.5 mm, 27 mm, 27.5 mm, or 28 mm. The width M of the rear heat exchange fin 21 is no less than 25 mm to ensure the size and heat exchange effect of the rear heat exchange fin 21. The width M of the rear heat exchange fin 21 is no greater than 28 mm to prevent the rear heat exchange fin 21 from being too large and thus affecting other components within the air conditioner 100.

[0103] In some embodiments of the present invention, the diameter of the rear heat exchange tube 22 is D1 and satisfies the following relationship: 3.6 mm ≤ D1 ≤ 7.5 mm. It is understood that the diameter D1 of the rear 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 diameter D1 of the rear heat exchange tube 22 is not less than 3.6 mm, which can ensure the flow rate of the refrigerant in the rear heat exchange tube 22 and the heat exchange effect of the rear heat exchanger 2; the diameter D1 of the rear heat exchange tube 22 is not greater than 7.5 mm, which can avoid the size of the rear heat exchange tube 22 being too large and avoid affecting the strength of the rear heat exchange fin 21.

[0104] In some embodiments of the present invention, the number of rear heat exchange tubes 22 is 12-16. It is understood that the number of rear heat exchange tubes 22 can be 12, 13, 14, 15, or 16. The rear heat exchange tubes 22 can be selectively arranged based on heat exchange requirements and the area where the rear heat exchange tubes 22 can be installed to meet different usage requirements.

[0105] In some embodiments of the present invention, Figure 1 As shown, the rear heat exchanger 2 has a plurality of rows of rear heat exchange tubes 22 arranged in sequence from the windward side to the leeward side, and the area between two adjacent rear heat exchange tubes 22 in each row of rear heat exchange tubes 22 on the rear heat exchange fins 21 is a first wind passing area 212, and the first wind passing area 212 has a first bridge fin 2121 and / or a first louver, and the first bridge fin 2121 is connected to the rear heat exchange fin 21 at both ends along the arrangement direction of each row of rear heat exchange tubes 22, and the middle part is separated from the rear heat exchange fin 21.

[0106] The first bridge fins 2121 include a first top sheet 21121 and a corresponding first support member 21122. The area between the first top sheet 21121 and the rear heat exchange fins 21, perpendicular to the rear heat exchange fins 21, is hollowed out, and the area on the rear heat exchange fins 21 where the first bridge fins 2121 are provided is also hollowed out. The provision of the first bridge fins 2121 disturbs the airflow as it passes through the first airflow region 212, changing its direction and enabling sufficient heat exchange with the rear heat exchange tubes 22, further enhancing the heat exchange efficiency of the rear heat exchange fins 21. The greater the number of first bridge fins 2121, the better the heat exchange efficiency of the rear heat exchange fins 21. Condensation generated during the heat exchange process is prone to dripping. The provision of the first bridge fins 2121 can address the issue of frosting in the air conditioner 100, making the rear heat exchange fins 21 more convenient for defrosting.

[0107] 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 rear heat exchange fin 21 between the rear heat exchange tube 22 at the lowest end of the second row of rear heat exchange tubes 22 and the reinforcing rib 2111, thereby changing the flow direction of the airflow and enabling the airflow to fully exchange heat with the rear heat exchange tube 22 on the rear heat exchanger 2, thereby further improving the heat exchange effect of the rear heat exchanger 2.

[0108] In some embodiments of the present invention, Figure 2 As shown, along the up and down direction (such as Figure 1 In the vertical direction (shown), the height Z1 of the rear heat exchanger 2 satisfies the following conditions: 95 mm ≤ Z1 ≤ 105 mm. It is understood that, in the vertical direction, the height Z1 of the rear heat exchanger 2 may be 95 mm, 95.5 mm, 96 mm, 96.5 mm, 97 mm, 97.5 mm, 98 mm, 98.5 mm, 99 mm, 99.5 mm, 100 mm, 100.5 mm, 101 mm, 101.5 mm, 102 mm, 102.5 mm, 103 mm, 103.5 mm, 104 mm, 104.5 mm, or 105 mm. In the up-down direction, the height Z1 of the rear heat exchanger 2 is not less than 95 mm, which can ensure the size of the rear heat exchanger 2 and the heat exchange effect of the rear heat exchanger 2; in the up-down direction, the height Z1 of the rear heat exchanger 2 is not greater than 105 mm, which can avoid the size of the rear heat exchanger 2 being too large and the rear heat exchanger 2 affecting other components in the air conditioner 100.

[0109] In some embodiments of the present invention, Figure 2As shown, the height Z2 of the front heat exchanger 1 in the vertical direction satisfies the following conditions: 170 mm ≤ Z2 ≤ 180 mm. It is understood that the height Z2 of the front heat exchanger 1 in the vertical direction may be 170 mm, 170.5 mm, 171 mm, 171.5 mm, 172 mm, 172.5 mm, 173 mm, 173.5 mm, 174 mm, 174.5 mm, 175 mm, 175.5 mm, 176 mm, 176.5 mm, 177 mm, 177.5 mm, 178 mm, 178.5 mm, 179 mm, 179.5 mm, or 180 mm. In the up-down direction, the height Z2 of the front heat exchanger 1 is not less than 170 mm, which can ensure the size of the front heat exchanger 1 and the heat exchange effect of the front heat exchanger 1; in the up-down direction, the height Z2 of the front heat exchanger 1 is not greater than 180 mm, which can avoid the size of the front heat exchanger 1 being too large and avoiding the front heat exchanger 1 affecting other components in the air conditioner 100.

[0110] In some embodiments of the present invention, the number of front heat exchange tubes 12 is 22-28. It is understandable that the number of front heat exchange tubes 12 can be 22, 23, 24, 25, 26, 27, or 28. The front heat exchange tubes 12 can be selectively arranged according to the heat exchange requirements and the area where the front heat exchange tubes 12 can be arranged to meet different usage requirements.

[0111] 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 rear heat exchange pipe 22 or the front heat exchange pipe 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 rear heat exchange pipe 22 and the front heat exchange pipe 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.

[0112] 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.

[0113] Example 1

[0114] Specifically, the heat exchanger assembly 10 includes a front heat exchanger 1 and a rear heat exchanger 2 .

[0115] like Figure 1 and Figure 2 As shown, the heat exchanger assembly 10 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 assembly 10 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 assembly 10 is a key device for heat transfer in the air conditioner 100. In cooling mode, the heat exchanger assembly 10 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.

[0116] The front heat exchanger 1 is located in front of the rear heat exchanger 2 and its upper end is connected to the upper end of the rear heat exchanger 2. The front heat exchanger 1 includes a plurality of front heat exchange fins 11 spaced apart in the length direction of the heat exchanger assembly 10 and a front heat exchange tube 12 passing through the plurality of front heat exchange fins 11. The front heat exchange tubes 12 are multiple rows spaced apart in the width direction of the front heat exchange fins 11. There are at least two rows of front heat exchange tubes 12 staggered along the length direction of the front heat exchanger 1. The corresponding At least one front heat exchange tube 12 in another row of front heat exchange tubes 12 is provided. External airflow enters the air conditioner 100, and the airflow flows to the front heat exchanger 1. After the airflow flows between two adjacent front heat exchange tubes 12 in the same row of front heat exchange tubes 12 in the front heat exchanger 1, it can flow to at least one front heat exchange tube 12 in another row of front heat exchange tubes 12, ensuring that the airflow can exchange heat with the front heat exchange tubes 12 as much as possible, which can better achieve the heat exchange effect of the front heat exchanger 1 and the heat exchange effect of the heat exchanger assembly 10.

[0117] The area between two adjacent front heat exchange tubes 12 in each row of front heat exchange tubes 12 is a wind-passing area 111, and a wind-passing structure 112 is provided on the wind-passing area 111. The wind-passing structure 112 can disturb the airflow when the airflow flows through the wind-passing area 111, and can change the flow direction of the airflow, so that the airflow can fully exchange heat with the front heat exchange tubes 12, further improving the heat exchange effect of the front heat exchange fins 11.

[0118] The airflow structures 112 located between the front heat exchange tubes 12 in a row on the leeward side are all bridge-plate structures 113. The bridge-plate structures 113 are connected to the front heat exchange fins 11 at both ends along the arrangement direction of the front heat exchange tubes 12 in a row on the leeward side, and the middle part is separated from the front heat exchange fins 11. By setting the bridge-plate structure 113, the airflow can be disturbed when flowing between the front heat exchange tubes 12 in a row on the leeward side, and the flow direction of the airflow can be changed, so that the airflow can fully exchange heat with the front heat exchange tubes 12, further improving the heat exchange effect of the front heat exchange fins 11, and the more bridge-plate structures 113 there are, the better the heat exchange effect of the front heat exchange fins 11.

[0119] The front heat exchange tubes 12 located in the windward row are arranged in the order S1, S2, S3, S4, S5, S6, S7, and S8 from bottom to top. The distances between S1 and S2, S2 and S3, S3 and S4, S5 and S6, and S7 and S8 are all Q1. The distances between S4 and S5, S6 and S7 are Q2, and Q2 > Q1. The airflow structure 112 between S1 and S2 is identical to the airflow structure 112 between S5 and S6, and is X1. The airflow structure 112 between S6 and S7 is identical to the airflow structure 112 between S4 and S5, and is X2. The airflow structure 112 between S2 and S3, the airflow structure 112 between S3 and S4, and the airflow structure 112 between S7 and S8 are identical, and are X3. The length of X3 is less than X2, and the number of X1 is less than X3. The wind-passing area 111 of the front heat exchange fin 11 , except for the wind-passing structures 112 between the front heat exchange tubes 12 in the leeward row, has a second bridge fin 1111 and / or a second louver.

[0120] The rear heat exchanger 2 includes a plurality of rear heat exchange fins 21 spaced apart along its length, and a rear heat exchange tube 22 extending through the plurality of rear heat exchange fins 21. The plurality of spaced-apart rear heat exchange fins 21 allows the rear heat exchange tube 22 to be secured at multiple locations on the rear heat exchanger 2, ensuring a more secure position and installation of the rear heat exchange tube 22. The lower ends of the rear heat exchange fins 21 have overlapping regions 211, which are equipped with reinforcing ribs 2111 to strengthen the edges of the rear heat exchange fins 21.

[0121] There are five spaced-apart reinforcing ribs 2111, which are arranged at intervals along the width direction of the rear heat exchange fin 21. Along the thickness direction of the rear heat exchange fin 21, the reinforcing ribs 2111 protrude from the rear heat exchange 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 rear heat exchange fin 21, respectively, which can reduce the risk of deformation of the rear heat exchange fin 21 and increase the flatness of the rear heat exchange fin 21.

[0122] The multiple reinforcing ribs 2111 have the same height, and the reinforcing ribs 2111 can be processed in a unified manner through stamping and other steps. This simplifies the manufacture of the reinforcing ribs 2111, reducing the manufacturing cost of the rear heat exchange fins 21. Along the width direction of the rear heat exchange fins 21, the distance between any two adjacent reinforcing ribs 2111 among the multiple reinforcing ribs 2111 is the same. During the processing of the reinforcing ribs 2111, the reinforcing ribs 2111 can be processed in a unified manner through stamping and other steps. This simplifies the manufacture of the reinforcing ribs 2111, reducing the manufacturing cost of the rear heat exchange fins 21. Along the width direction of the rear heat exchange fins 21, the multiple reinforcing ribs 2111 have the same width, and the reinforcing ribs 2111 can be processed in a unified manner through stamping and other steps. This simplifies the manufacture of the reinforcing ribs 2111, reducing the manufacturing cost of the rear heat exchange fins 21.

[0123] The rear heat exchange tubes 22 are the first row of heat exchange tubes 221 and the second row of heat exchange tubes 222 arranged in sequence from the windward side to the leeward side. Along the length direction of the rear heat exchange fins 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. A bridge piece 2112 is provided between the rear heat exchange tube 22 at the lowest end of the second row of heat exchange tubes 222 on the rear heat exchange fins 21 and the reinforcing ribs 2111. The bridge piece 2112 is connected to the rear heat exchange fins 21 at both ends along the arrangement direction of the second row of heat exchange tubes 222, and is separated from the rear heat exchange fins 21 in the middle. The bridge piece 2112 includes a top piece 21121 and a corresponding support piece 21122. The top piece 21121 and the rear heat exchange fins 21 are perpendicular to the rear heat exchange fins 21. The location of the rear heat exchange fin 21 is hollowed out, and the location where the bridge fins 2112 are provided on the rear heat exchange fin 21 is hollowed out. By providing the bridge fins 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 ribs 2111, changing the flow direction of the airflow, allowing the airflow to fully exchange heat with the rear heat exchange tube 22, further improving the heat exchange effect of the rear heat exchange fin 21. The more bridge fins 2112 there are, the better the heat exchange effect of the rear heat exchange fin 21. The number of bridge fins 2112 is four.

[0124] The distance between the lower end of the overlapping area 211 (ie, the lower end of the rear heat exchange fin 21 ) and the adjacent rear heat exchange tube 22 is greater than the distance between two adjacent rear heat exchange tubes 22 .

[0125] The rear heat exchanger 2 has multiple rows of rear heat exchange tubes 22 arranged in sequence from the windward side to the leeward side. The area between two adjacent rear heat exchange tubes 22 in each row of rear heat exchange tubes 22 on the rear heat exchange fins 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 rear heat exchange fins 21 at both ends along the arrangement direction of each row of rear heat exchange tubes 22, and the middle part is separated from the rear heat exchange fins 21.

[0126] The first bridge fins 2121 include a first top sheet 21121 and a corresponding first support member 21122. The area between the first top sheet 21121 and the rear heat exchange fins 21, perpendicular to the rear heat exchange fins 21, is hollowed out, and the area on the rear heat exchange fins 21 where the first bridge fins 2121 are provided is also hollowed out. The provision of the first bridge fins 2121 disturbs the airflow as it passes through the first airflow region 212, changing its direction and enabling sufficient heat exchange with the rear heat exchange tubes 22, further enhancing the heat exchange efficiency of the rear heat exchange fins 21. The greater the number of first bridge fins 2121, the better the heat exchange efficiency of the rear heat exchange fins 21. Condensation generated during the heat exchange process is prone to dripping. The provision of the first bridge fins 2121 can address the issue of frosting in the air conditioner 100, making the rear heat exchange fins 21 more convenient for defrosting.

[0127] The front heat exchanger 1 includes a plurality of front heat exchange fins 11 spaced apart in the longitudinal direction of the front heat exchanger 1 and a front heat exchange tube 12 passing through the plurality of front heat exchange fins 11. By providing a plurality of spaced apart front heat exchange fins 11, the front heat exchange tube 12 can be fixed at a plurality of positions on the front heat exchanger 1, so that the position of the front heat exchange tube 12 on the front heat exchanger 1 can be more reliable, and the installation of the front heat exchange tube 12 can be more reliable.

[0128] The distance P1 between adjacent front heat exchange tubes 12 in each row of front heat exchange tubes 12 on the front heat exchanger 1 is the same, resulting in a more uniform layout of the front heat exchange tubes 12 on the front heat exchanger 1, better heat exchange performance, and easier assembly. The distance P3 between adjacent front heat exchange tubes 12 in each row of rear heat exchange tubes 22 on the rear heat exchanger 2 is the same, resulting in a more uniform layout of the rear heat exchange tubes 22 on the rear heat exchanger 2, better heat exchange performance, and easier assembly.

[0129] 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 rear heat exchange tube 22 or the front 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. This can change the flow direction of the airflow, allowing the airflow to fully exchange heat with the rear heat exchange tube 22 and the front 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.

[0130] Example 2

[0131] The structure of this embodiment is substantially the same as that of the first embodiment, wherein the same components are designated by the same reference numerals. The only difference is that the tube spacing between two adjacent front heat exchange tubes 12 in each row of front heat exchange tubes 12 on the front heat exchanger 1 is P1 or P2. The front heat exchange tubes 12 can be arranged according to the heat exchange requirements at different positions of the front heat exchanger 1 to improve the heat exchange efficiency of the front heat exchanger 1.

[0132] Example 3

[0133] 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 rear heat exchange fin 21 and the reinforcing rib 2111. The louver structure 2113 opens toward the windward side of the rear heat exchanger 2, or the leeward side of the rear heat exchanger 2. The louver structure 2113 provides a superior wind-disturbing effect, effectively disturbing the airflow as it passes between the bottommost heat exchange tube in the second row of heat exchange tubes 222 on the rear heat exchange fin 21 and the reinforcing rib 2111, thereby redirecting the airflow and enabling sufficient heat exchange with the rear heat exchange tube 22 on the rear heat exchanger 2, further enhancing the heat exchange efficiency of the rear heat exchanger 2. The number of louver structures 2113 is three.

[0134] Example 4

[0135] The structure of this embodiment is substantially the same as that of the first embodiment, wherein the same components are designated by the same reference numerals. The only difference is that along the thickness direction of the rear heat exchange fin 21, a plurality of reinforcing ribs 2111 protrude toward the same side, and the processing and manufacturing of the reinforcing ribs 2111 is relatively convenient.

[0136] The air conditioner 100 according to the embodiment of the present invention includes a housing 30 , a wind wheel 20 and the above-mentioned heat exchanger assembly 10 .

[0137] Specifically, the wind wheel 20 is arranged in the shell 30, the heat exchanger assembly 10 is arranged in the shell 30, the rear heat exchanger 2 is located on the upper rear side of the wind wheel 20, and the front heat exchanger 1 is located on the upper front side and the front side of the wind wheel 20. The heat exchanger assembly 10 semi-surrounds the wind wheel 20. The shell 30 is provided with an air inlet 301 and an air outlet 302. Under the driving action of the wind wheel 20, the airflow outside the air conditioner 100 enters the inside of the shell 30 of the air conditioner 100 from the air inlet 301, and the airflow in the shell 30 flows through the heat exchanger assembly 10 and exchanges heat with the heat exchanger assembly 10. The airflow after the heat exchange is completed is blown out through the air outlet 302.

[0138] Furthermore, an air inlet grille is provided at the air inlet 301. On the one hand, the air inlet grille can prevent hands or other foreign objects from entering the interior of the air conditioner 100, protecting the safety of the user and ensuring the normal operation of the air conditioner 100; on the other hand, the air inlet grille can prevent insects, rats, etc. from entering the shell 30 of the air conditioner 100 and causing damage to the air conditioner 100, thereby ensuring the normal operation of the air conditioner 100 and ensuring the beautiful appearance of the air conditioner 100.

[0139] Optionally, the air inlet grille is detachably connected to the shell 30. The air inlet grille can ensure the beautiful appearance of the shell 30. After the air inlet grille is removed, it is convenient to repair and replace components in the air conditioner 100. At the same time, it is convenient to clean the air inlet grille, avoiding dust accumulation on the air inlet grille due to long-term use.

[0140] According to the air conditioner 100 of the embodiment of the present invention, by setting the tube spacing of multiple front-row heat exchange tubes 121 located in a row on the windward side among the multiple rows of front heat exchange tubes 12 to a first tube spacing and a second tube spacing with different distances, the positions of the front-row heat exchange tubes 121 can be arranged more flexibly, and the front-row heat exchange tubes 121 can be arranged as much as possible in positions where heat exchange with the airflow is better. The external airflow enters the air conditioner 100, and the airflow flows to the front heat exchanger 1. The airflow flows through the front-row heat exchange tubes 121, and the heat exchange effect with the front-row heat exchange tubes 121 is better, ensuring that the airflow can exchange heat with the front-row heat exchange tubes 121 as much as possible, which can better achieve the heat exchange effect of the front heat exchanger 1 and the heat exchange effect of the heat exchanger assembly 10.

[0141] In some embodiments of the present invention, the vertical dimension of the air conditioner 100 is H3 and satisfies the following conditions: 280mm≤H3≤300mm. It is understood that the vertical dimension H3 of the air conditioner 100 can be 280mm, 282mm, 284mm, 286mm, 288mm, 290mm, 292mm, 294mm, 296mm, 298mm, or 300mm. If the vertical dimension H3 of the air conditioner 100 is not less than 280mm, there is sufficient space inside the air conditioner 100 to install the impeller 20 and the heat exchanger assembly 10. If the vertical dimension H3 of the air conditioner 100 is not greater than 300mm, the height 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.

[0142] In some embodiments of the present invention, the dimension L3 of the air conditioner 100 along the front-to-back direction satisfies the following conditions: 190 mm ≤ L3 ≤ 230 mm. It is understood that the dimension L3 of the air conditioner 100 along the front-to-back direction may be 190 mm, 195 mm, 200 mm, 205 mm, 210 mm, 215 mm, 220 mm, 225 mm, or 230 mm. 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.

[0143] In some embodiments of the present invention, Figure 2 As 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. For example, the direction of the support force exerted by the support base 303 on the overlapping region 211 passes through the reinforcing ribs 2111, or the support base 303 includes a contact surface that contacts the overlapping region 211, and a direction perpendicular to the contact surface passes through the reinforcing ribs 2111. The reinforcing ribs 2111 are provided at positions corresponding to the overlapping region 211 and the support base 303 to reduce deformation of the overlapping region 211.
