[0036] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. 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.

[0037] It should be understood that the up, down, front and back directions of the present invention are as follows: Figure 1 shown.

[0038] A heat exchanger assembly 10 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0039] 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 .

[0040] Specifically, if Figure 1 As shown, the heat exchanger assembly 10 is used in an air conditioner 100. 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.

[0041] like Figure 1 As shown, the air conditioner 100 includes a rotor 20. The rotation of the rotor 20 draws indoor air into the air conditioner 100, filters it, and then blows it out of the air conditioner 100, creating a circulating airflow that helps circulate the indoor air and improves the freshness and comfort of the air. In cooling mode, the rotor 20 draws air from the air conditioner 100, exchanges heat with the refrigerant in the heat exchanger assembly 10, and cools it down. The cooled air is then blown out of the air conditioner 100, lowering the indoor temperature. In heating mode, the rotor 20 draws air from the air conditioner 100, exchanges heat with the refrigerant in the heat exchanger assembly 10, and heats it up. The heated air is then blown out of the air conditioner 100, raising the indoor temperature. The continuous rotation of the rotor 20 ensures a consistent and uniform cooling or heating effect.

[0042] like Figure 1 and Figure 2As shown, the rear heat exchanger 2 is located on the upper rear side of the wind wheel 20 and can exchange heat with the air that is sucked into the air conditioner 100 from the upper rear side of the wind wheel 20. The front heat exchanger 1 includes a first section 11 located on the upper front side of the wind wheel 20 and a second section 12 located on the front side of the wind wheel 20. The first section 11 can exchange heat with the air that is sucked into the air conditioner 100 from the upper front side of the wind wheel 20, and the second section 12 can exchange heat with the air that is sucked into the air conditioner 100 from the front side of the wind wheel 20.

[0043] The second section 12 is arc-shaped and convex away from the wind rotor 20. The second section 12 can effectively avoid the wind rotor 20, and a certain gap is maintained between the wind rotor 20 and the second section 12, facilitating the rotation of the wind rotor 20 and the flow of air. A first avoidance groove 121 is provided on the side of the second section 12 near the wind rotor 20. The first avoidance groove 121 extends along the axial direction of the wind rotor 20 and can penetrate the second section 12. The first avoidance groove 121 can better avoid the wind rotor 20, allowing the heat exchanger assembly 10 to adapt to larger wind rotors 20. The heat exchanger assembly 10 is compatible with wind rotors 20 of different sizes, increasing the versatility of the heat exchanger assembly 10 and reducing the material consumption of the second section 12 of the front heat exchanger 1.

[0044] According to the heat exchanger assembly 10 of the present invention, the rear heat exchanger 2 is disposed on the upper rear side of the rotor 20, and the first section 11 and second section 12 of the front heat exchanger 1 are disposed on the upper front side and the front side of the rotor 20, respectively. In the direction of airflow, the front heat exchanger 1 and the rear heat exchanger 2 are disposed upstream of the rotor 20 and semi-surround the rotor 20, facilitating heat exchange between air entering the air conditioner 100 and the refrigerant within the heat exchanger assembly 10. Furthermore, a first avoidance groove 121 is provided on a side of the second section 12 protruding away from the rotor 20 and proximate to the rotor 20. The first avoidance groove 121 extends along the axial direction of the rotor 20, enabling the heat exchanger assembly 10 to adapt to larger rotors 20. The heat exchanger assembly 10 is compatible with rotors 20 of different sizes, thereby increasing the versatility of the heat exchanger assembly 10 and reducing the material consumption of the second section 12 of the front heat exchanger 1.

[0045] In some embodiments of the present invention, Figure 1 and Figure 2As shown, on the projection of the plane perpendicular to the axis of the wind wheel 20, the bottom wall of the first avoidance groove 121 includes a first arc segment 1211. The first arc segment 1211 is a single arc segment or multiple arc segments connected in sequence. The first arc segment 1211 can reduce the contact between the airflow between the wind wheel 20 and the second segment 12 and the corner of the front heat exchanger 1, thereby avoiding the airflow from producing a sharp whistle. The space utilization of the front heat exchanger 1 is better, which can reduce the problem of water accumulation at the outer corners of the bend, and can avoid the accumulated water from dripping into the air duct of the air conditioner 100 and causing water blowing as much as possible, thereby improving the quality of the air conditioner 100.

[0046] It can be understood that the first arc segment 1211 is a single arc segment, which facilitates the processing of the first avoidance groove 121; the first arc segment 1211 is a plurality of arc segments connected in sequence, which can ensure smooth transitions between the arc segments, avoid sharp corners or unevenness that may exist in a single arc segment, and avoid the airflow from producing a sharp whistle.

[0047] R1R1R1R1R1R1Further, as Figure 3 and Figure 4 As shown, along the vertical direction, first arc segment 1211 has first and second straight segments 1212 and 1213 at either end, respectively. First straight segment 1212 can be a single straight segment or multiple straight segments, while second straight segment 1213 can be a single straight segment or multiple straight segments. First and second straight segments 1212 and 1213 facilitate a smooth connection between first arc segment 1211 and the sidewalls of first avoidance groove 121, avoiding sharp corners or unevenness within first avoidance groove 121 and preventing a sharp whistling sound from the airflow.

[0048] It is understood that the first straight segment 1212 is a single straight segment, which facilitates the processing of the first avoidance groove 121. The first straight segment 1212 is composed of multiple straight segments, which can ensure smooth transitions between the straight segments, avoiding the sharp corners or unevenness that may exist in a single straight segment, and preventing the airflow from producing a relatively sharp whistling sound. The second straight segment 1213 is a single straight segment, which facilitates the processing of the first avoidance groove 121. The second straight segment 1213 is composed of multiple straight segments, which can ensure smooth transitions between the straight segments, avoiding the sharp corners or unevenness that may exist in a single straight segment, and preventing the airflow from producing a relatively sharp whistling sound.

[0049] In some embodiments of the present invention, Figure 1 and Figure 2As shown, a second avoidance groove 122 is provided on the side of the second section 12 away from the wind wheel 20. The second avoidance groove 122 extends along the axial direction of the wind wheel 20. The second avoidance groove 122 can pass through the second section 12. The second avoidance groove 122 can better avoid other components of the air conditioner 100, so that the heat exchanger assembly 10 can be compatible with air conditioners 100 of different sizes, increase the versatility of the heat exchanger assembly 10, and reduce the material usage of the second section 12 of the front heat exchanger 1.

[0050] Furthermore, if Figure 1 and Figure 2 As shown, on the projection of the plane perpendicular to the axis of the wind wheel 20, the bottom wall of the second avoidance groove 122 includes a second arc segment 1221, and the second arc segment 1221 is a single arc segment or multiple arc segments. The second arc segment 1221 can reduce the contact between the airflow between the shell 30 of the air conditioner 100 and the second section 12 and the corner of the front heat exchanger 1, thereby avoiding the airflow from producing a sharp whistle. The space utilization of the front heat exchanger 1 is better, which can reduce the problem of water accumulation at the outer corners of the bend, and can avoid the accumulated water from dripping into the air duct of the air conditioner 100 and causing water blowing as much as possible, thereby improving the quality of the air conditioner 100.

[0051] It can be understood that the second arc segment 1221 is a single arc segment, which facilitates the processing of the second avoidance groove 122; the second arc segment 1221 is a plurality of arc segments connected in sequence, which can ensure smooth transitions between the arc segments, avoid sharp corners or unevenness that may exist in a single arc segment, and avoid the airflow from producing a sharp whistle.

[0052] Furthermore, if Figure 1 and Figure 2 As shown, the radius of at least one arc segment of the first arc segment 1211 is R1, and the radius of at least one arc segment of the second arc segment 1221 is R2, satisfying the following relationship: R2>R1. It is understood that the radius of the second arc segment 1221 is greater than the radius of the first arc segment 1211, resulting in a larger processing radius at the second arc segment 1221 located outside the second segment 12, facilitating processing and manufacturing of the second arc segment 1221.

[0053] Furthermore, 85≤R1≤98mm. It is understandable that the radius R1 of the first arc segment 1211 can be 85mm, 86mm, 87mm, 88mm, 89mm, 90mm, 91mm, 92mm, 93mm, 94mm, 95mm, 96mm, 97mm, or 98mm. The radius R1 of the first arc segment 1211 is not less than 85mm, which can make the arc radius of the first arc segment 1211 larger and make the first arc segment 1211 smoother. The radius R1 of the first arc segment 1211 is not greater than 98mm, which can prevent the arc radius of the first arc segment 1211 from being too large, thereby avoiding affecting the connection effect between the first arc segment 1211 and other positions of the first avoidance groove 121.

[0054] Furthermore, 98≤R2≤110mm. It is understandable that the radius R2 of the second arc segment 1221 can be 98mm, 99mm, 100mm, 101mm, 102mm, 103mm, 104mm, 105mm, 106mm, 107mm, 108mm, 109mm, or 110mm. The radius R2 of the second arc segment 1221 is not less than 95mm, which can make the arc radius of the second arc segment 1221 larger and make the second arc segment 1221 smoother. The radius R2 of the second arc segment 1221 is not greater than 110mm, which can prevent the arc radius of the second arc segment 1221 from being too large, thereby avoiding affecting the connection effect between the second arc segment 1221 and other positions of the second avoidance groove 122.

[0055] Furthermore, if Figure 3 and Figure 4 As shown, along the vertical direction, a third straight segment 1222 and a fourth straight segment 1223 are respectively provided at the two ends of the second arc segment 1221. The third straight segment 1222 can be a single straight segment or multiple straight segments, and the fourth straight segment 1223 can be a single straight segment or multiple straight segments. The third straight segment 1222 and the fourth straight segment 1223 facilitate a smooth connection between the second arc segment 1221 and the sidewall of the second avoidance groove 122, avoiding any sharp corners or unevenness within the second avoidance groove 122, and preventing the airflow from producing a sharp whistling sound.

[0056] It is understood that the third straight line segment 1222 is a single straight line segment, which facilitates the processing of the second avoidance groove 122. The third straight line segment 1222 is composed of multiple straight line segments, which can ensure smooth transitions between the straight line segments, avoiding the sharp corners or unevenness that may exist in a single straight line segment, and preventing the airflow from producing a relatively sharp whistling sound. The fourth straight line segment 1223 is a single straight line segment, which facilitates the processing of the second avoidance groove 122. The fourth straight line segment 1223 is composed of multiple straight line segments, which can ensure smooth transitions between the straight line segments, avoiding the sharp corners or unevenness that may exist in a single straight line segment, and preventing the airflow from producing a relatively sharp whistling sound.

[0057] In some embodiments of the present invention, Figure 2 As shown, both the front heat exchanger 1 and the rear heat exchanger 2 include multiple fins 13 spaced axially along the rotor 20. The fins 13 of the front heat exchanger 1 are provided with a first notch on the side facing the rotor 20. These first notches together form a first avoidance slot 121, allowing the first avoidance slot 121 to penetrate the second section 12 of the front heat exchanger 1. The fins 13 of the front heat exchanger 1 are provided with a second notch on the side facing away from the rotor 20. These second notches together form a second avoidance slot 122, allowing the second avoidance slot 122 to penetrate the second section 12 of the front heat exchanger 1. This allows the multiple fins 13 to avoid the rotor 20 and other components of the air conditioner 100, increasing the versatility of the heat exchanger assembly 10 and reducing the material usage of the second section 12 of the front heat exchanger 1.

[0058] In some embodiments of the present invention, the second avoidance groove 122 is formed on the side of the second section 12 away from the first avoidance groove 121, and the second avoidance groove 122 and the first avoidance groove 121 are arranged correspondingly, so that the positions of the second avoidance groove 122 and the first avoidance groove 121 are relatively corresponding, thereby reducing the pressure at the first avoidance groove 121.

[0059] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the rear heat exchanger 2 is tilted backward in the top-down direction, and the first section 11 is tilted forward in the top-down direction. The upper end of the rear heat exchanger 2 is connected to the upper end of the first section 11 so that the heat exchanger assembly 10 semi-surrounds the wind wheel 20. Along the airflow direction, the front heat exchanger 1 and the rear heat exchanger 2 are arranged upstream of the wind wheel 20 and semi-surround the wind wheel 20, so as to facilitate heat exchange between the air entering the air conditioner 100 and the refrigerant in the heat exchanger assembly 10.

[0060] In some embodiments of the present utility model, the minimum distance between the connecting line between the upper edge and the lower edge of the first avoidance groove 121 and the bottom surface of the first avoidance groove 121 is H1, where 6 mm < H1 < 10 mm. It can be understood that the minimum distance between the connecting line between the upper edge and the lower edge of the first avoidance groove 121 and the bottom surface of the first avoidance groove 121 can be 6.1 mm, 6.3 mm, 6.5 mm, 6.7 mm, 6.9 mm, 7.1 mm, 7.3 mm, 7.5 mm, 7.7 mm, 7.9 mm, 8.1 mm, 8.3 mm, 8.5 mm, 8.7 mm, 8.9 mm, 9.1 mm, 9.3 mm, 9.5 mm, 9.7 mm or 9.9 mm. The minimum distance between the connecting line between the upper edge and the lower edge of the first avoidance groove 121 and the bottom surface of the first avoidance groove 121 being greater than 6 mm can enable the first avoidance groove 121 to have sufficient avoidance distance, avoid interference between the first avoidance groove 121 and the wind wheel 20, and ensure the normal operation of the wind wheel 20; the minimum distance between the connecting line between the upper edge and the lower edge of the first avoidance groove 121 and the bottom surface of the first avoidance groove 121 being less than 10 mm can avoid the size of the first avoidance groove 121 being too large, avoid affecting the heat exchange efficiency of the front heat exchanger 1, and avoid affecting the heat exchange efficiency of the heat exchanger assembly 10.

[0061] In some embodiments of the present utility model, the distance between the upper edge and the lower edge of the first avoidance groove 121 is D1, where 50 mm < D1 < 100 mm. It can be understood that the distance between the upper edge and the lower edge of the first avoidance groove 121 can be 50.1 mm, 55 mm, 60 mm, 65 mm, 70 mm, 75 mm, 80 mm, 85 mm, 90 mm, 95 mm or 99.9 mm. The distance between the upper edge and the lower edge of the first avoidance groove 121 being greater than 50.1 mm can enable the first avoidance groove 121 to have sufficient avoidance distance, avoid interference between the first avoidance groove 121 and the wind wheel 20, and ensure the normal operation of the wind wheel 20; the distance between the upper edge and the lower edge of the first avoidance groove 121 being less than 100 mm can avoid the size of the first avoidance groove 121 being too large, avoid affecting the heat exchange efficiency of the front heat exchanger 1, and avoid affecting the heat exchange efficiency of the heat exchanger assembly 10.

[0062] The heat exchanger assembly 10 according to the above embodiments is used in an air conditioner 100. Under standard conditions (refrigeration condition: temperature 27°, humidity 19°), compared with a traditional air conditioner, the comparison is as shown in the following table:

[0063]

[0064] Table 1 Comparison of heat exchange capacity between conventional air conditioners and this embodiment

[0067] Specifically, if Figure 1 As shown, the housing 30 is provided with an air inlet 301 and an air outlet 302. Driven by the impeller 20, airflow outside the air conditioner 100 enters the housing 30 of the air conditioner 100 through the air inlet 301. The airflow within the housing 30 flows through the heat exchanger assembly 10 and exchanges heat with the heat exchanger assembly 10. The airflow after heat exchange is blown out through the air outlet 302. In the direction of airflow, the front heat exchanger 1 and the rear heat exchanger 2 are located upstream of the impeller 20 and semi-enclose the impeller 20, facilitating heat exchange between the air entering the air conditioner 100 and the refrigerant in the heat exchanger assembly 10.

[0068] According to an embodiment of the present invention, an air conditioner 100 employs a heat exchanger assembly 10. The rear heat exchanger 2 is positioned on the upper rear side of the rotor 20, and the first section 11 and second section 12 of the front heat exchanger 1 are positioned on the upper front side and the front side of the rotor 20, respectively. In the direction of airflow, the front heat exchanger 1 and the rear heat exchanger 2 are positioned upstream of the rotor 20 and semi-surround the rotor 20, facilitating heat exchange between air entering the air conditioner 100 and the refrigerant within the heat exchanger assembly 10. Furthermore, a first avoidance groove 121 is provided on a side of the second section 12, which is curved and convex away from the rotor 20 and is located near the rotor 20. The first avoidance groove 121 extends along the axial direction of the rotor 20, enabling the heat exchanger assembly 10 to adapt to larger rotors 20. This allows the heat exchanger assembly 10 to be compatible with rotors 20 of different sizes, thereby increasing the versatility of the heat exchanger assembly 10 and reducing the material consumption of the second section 12 of the front heat exchanger 1.

[0069] In some embodiments of the present utility model, the minimum distance between the wind wheel 20 and the bottom surface of the first avoidance groove 121 is defined as L1, the structure of the front heat exchanger 1 except the first avoidance groove 121 is defined as the heat exchange part, the minimum distance between the wind wheel 20 and the heat exchange part is defined as L2, and -1mm < L1 - L2 < 1mm. It can be understood that the difference between the minimum distance between the wind wheel 20 and the bottom surface of the first avoidance groove 121 and the minimum distance between the wind wheel 20 and the heat exchange part can be -0.9mm, -0.7mm, -0.5mm, -0.3mm, -0.1mm, 0.1mm, 0.3mm, 0.5mm, 0.7mm or 0.9mm. At this time, the length of the first avoidance groove 121 in the up and down direction is relatively reasonable, avoiding the first avoidance groove 121 being too long in the up and down direction, and the first avoidance groove 121 is only formed at the position closest to the wind wheel 20, thereby avoiding the first avoidance groove 121 being too long and affecting the heat exchange efficiency.
