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

[0040] The heat exchanger 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0041] like Figure 1 As shown, the heat exchanger 100 according to an embodiment of the present invention includes a heat exchanger body 10 .

[0042] Specifically, if Figure 4 As shown, the heat exchanger 100 can be used in an air conditioner 1000. For example, the air conditioner 1000 is used indoors. The heat exchanger 100 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 100 is a key device for heat transfer in the air conditioner 1000. In cooling mode, the heat exchanger 100 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.

[0043] like Figure 1 As shown, in the projection in the plane perpendicular to the length direction of the heat exchanger body 10, the heat exchanger body 10 is in the thickness direction of the heat exchanger body 10 (such as Figure 1The curved shape of the heat exchanger body 10 (shown in the front-to-back direction) can increase the size of the heat exchange area of ​​the heat exchanger body 10 and enhance the heat exchange effect of the heat exchanger 100. A protrusion 1 and a groove 2 are formed on both sides of the heat exchanger body 10 in the thickness direction, respectively. The bottom of the groove 2 is provided with a first avoidance groove 221, which extends along the length of the heat exchanger body 10. It can be understood that the first avoidance groove 221 runs through the heat exchanger body 10, which can reduce the distance between the heat exchange tube 30 on the side of the heat exchanger body 10 near the groove 2 and the edge of the heat exchanger body 10, thereby improving the heat exchange efficiency of the heat exchanger 100; it can also avoid other components within the air conditioner 1000, increase the versatility of the heat exchanger 100, and reduce the material consumption of the heat exchanger 100.

[0044] According to the heat exchanger 100 of the embodiment of the present invention, a first avoidance groove 221 is provided at the bottom of the groove 2 on one side of the heat exchanger body 10 in the thickness direction. The first avoidance groove 221 extends along the length direction of the heat exchanger body 10, thereby reducing the distance between the heat exchange tube 30 on the side of the heat exchanger body 10 close to the groove 2 and the edge of the heat exchanger body 10, thereby improving the heat exchange efficiency of the heat exchanger 100; and avoiding other components in the air conditioner 1000, thereby increasing the versatility of the heat exchanger 100 and reducing the material usage of the heat exchanger 100.

[0045] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, in the projection of a plane perpendicular to the length of the heat exchanger body 10, the bottom wall of the first avoidance groove 221 includes a first arc segment 2211 that protrudes toward the protrusion 1. The first arc segment 2211 can reduce the contact between the airflow and the corner of the heat exchanger body 10 at the groove 2, preventing the airflow from producing a sharp whistling sound. This improves the space utilization of the heat exchanger body 10, reduces the problem of water accumulation at the outer corners of the bend, and minimizes the possibility of accumulated water dripping into the air duct of the air conditioner 1000 and causing water blowing, thereby improving the quality of the air conditioner 1000.

[0046] In addition, the first arc segment 2211 is a single arc segment or multiple arc segments connected in sequence. The first arc segment 2211 is a single arc segment, which facilitates the processing of the first avoidance groove 221; the first arc segment 2211 is multiple 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 sharper whistle.

[0047] Further, if Figure 1 and Figure 2As shown, in the projection of a plane perpendicular to the length direction of the heat exchanger body 10, the inner wall of the groove 2 includes a first straight edge 21, a first arc edge 22 and a second straight edge 23 connected in sequence, and the first avoidance groove 221 is provided on the first arc edge 22. The first straight edge 21 is in the direction from top to bottom (as shown in FIG. Figure 1 The first arc edge 22 is an arc convex toward one side in the thickness direction of the heat exchanger body 10, and the second straight edge 23 extends straight backward in the top-to-bottom direction. The arc of the first arc edge 22 is tangent to the first straight edge 21, and the arc of the first arc edge 22 is tangent to the straight segment of the second straight edge 23. At this time, the transitions at various locations on the inner wall of the groove 2 are relatively smooth. When the airflow flows through the inner wall of the groove 2, it can avoid contact with the corners of the inner wall of the groove 2, thereby preventing the airflow from producing a sharp whistling sound. The space utilization of the heat exchanger body 10 is better, which can reduce the problem of water accumulation at the outer corners of the bends, and can minimize the possibility of accumulated water dripping into the air duct of the air conditioner 1000 and causing water blowing, thereby improving the quality of the air conditioner 1000.

[0048] Furthermore, if Figure 1 and Figure 2 As shown, the radius of the first arc edge 22 is R1, and the radius of the first arc segment 2211 is R2, and they satisfy: R1>R2. It is understood that the radius of the first arc edge 22 is larger than the radius of the first arc segment 2211, which reduces the machining radius at the first arc segment 2211 and facilitates machining and manufacturing at the first arc segment 2211.

[0049] Furthermore, 50mm≤R1≤60mm. It is understandable that the radius R1 of the first arc edge 22 can be 50mm, 51mm, 52mm, 53mm, 54mm, 55mm, 56mm, 57mm, 58mm, 59mm, or 60mm. If the radius R1 of the first arc edge 22 is not less than 50mm, the radius of the first arc edge 22 can be larger, making the first arc edge 22 smoother. If the radius R1 of the first arc edge 22 is not greater than 60mm, the radius of the first arc edge 22 can be prevented from being too large, thereby preventing the smooth transition between the first arc edge 22 and the first straight edge 21 and the second straight edge 23 from being affected.

[0050] Furthermore, 40mm≤R2≤50mm. It is understandable that the radius R2 of the first arc segment 2211 can be 40mm, 41mm, 42mm, 43mm, 44mm, 45mm, 46mm, 47mm, 48mm, 49mm or 50mm. The radius R2 of the first arc segment 2211 is not less than 40mm, which can make the arc radius of the first arc segment 2211 larger and make the first arc segment 2211 smoother; the radius R2 of the first arc segment 2211 is not greater than 50mm, which can avoid the arc radius of the first arc segment 2211 being too large, thereby avoiding affecting the connection effect between the first arc segment 2211 and other positions of the first avoidance groove 221.

[0051] The first straight edge 21 and the second straight edge 23 are both tangent to the first arc edge 22 , and the transition between the first straight edge 21 , the first arc edge 22 and the second straight edge 23 is relatively smooth.

[0052] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, in a projection on a plane perpendicular to the length of the heat exchanger body 10, the bottom wall of the first avoidance groove 221 also includes a first straight segment 2212 and a second straight segment 2213 connecting the two ends of the first arc segment 2211. It is understood that the first straight segment 2212 can be a single straight segment or multiple straight segments, and the second straight segment 2213 can be a single straight segment or multiple straight segments. The first straight segment 2212 and the second straight segment 2213 facilitate a smooth connection between the first arc segment 2211 and the sidewall of the first avoidance groove 221, avoiding any sharp corners or unevenness within the first avoidance groove 221, and preventing the airflow from producing a sharp whistling sound.

[0053] It is understood that the first straight segment 2212 is a single straight segment, which facilitates the processing of the first avoidance groove 221. The first straight segment 2212 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 2213 is a single straight segment, which facilitates the processing of the first avoidance groove 221. The second straight segment 2213 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.

[0054] In some embodiments of the present invention, Figure 1 and Figure 2As shown, a second avoidance groove 121 is provided on the top of the protrusion 1, and the second avoidance groove 121 extends along the length direction of the heat exchanger body 10. It can be understood that the second avoidance groove 121 runs through the heat exchanger body 10. The second avoidance groove 121 can better avoid other components of the air conditioner 1000, so that the heat exchanger 100 can be compatible with air conditioners 1000 of different sizes, increase the versatility of the heat exchanger 100, and reduce the material consumption of the heat exchanger body 10.

[0055] Further, if Figure 1 and Figure 2 As shown, in the projection of a plane perpendicular to the length of the heat exchanger body 10, the bottom wall of the second avoidance groove 121 includes a second arc segment 1211 that protrudes away from the groove 2. The second arc segment 1211 can reduce the contact between the airflow and the corner of the heat exchanger body 10 at the protrusion 1, preventing the airflow from producing a sharp whistling sound. This improves the space utilization of the heat exchanger body 10, reduces the problem of water accumulation at the outer corners of the bend, and minimizes the possibility of accumulated water dripping into the air duct of the air conditioner 1000 and causing water blowing, thereby improving the quality of the air conditioner 1000.

[0056] In addition, the second arc segment 1211 is a single arc segment or multiple arc segments connected in sequence. The second arc segment 1211 is a single arc segment, which facilitates the processing of the second avoidance groove 121; the second arc segment 1211 is multiple 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.

[0057] Further, if Figure 1 and Figure 2 As shown, the radius of the first arc segment 2211 is R2, and the radius of the second arc segment 1211 is R3, satisfying the following relationship: R3>R2. It is understood that the radius of the second arc segment 1211 is greater than the radius of the first arc segment 2211, which makes the processing radius of the second arc segment 1211 located at the protrusion 1 more reasonable, facilitating the processing and manufacturing of the second arc segment 1211.

[0058] Furthermore, 52mm≤R3≤58mm. It is understandable that the radius R3 of the second arc segment 1211 can be 52mm, 52.5mm, 53mm, 53.5mm, 54mm, 54.5mm, 55mm, 55.5mm, 56mm, 56.5mm, 57mm, 57.5mm, or 58mm. If the radius R3 of the second arc segment 1211 is not less than 52mm, the arc radius of the second arc segment 1211 can be larger, making the second arc segment 1211 smoother. If the radius R3 of the second arc segment 1211 is not greater than 58mm, the arc radius of the second arc segment 1211 can be prevented from being too large, thereby preventing the connection between the second arc segment 1211 and other positions of the second avoidance groove 121 from being affected.

[0059] In some embodiments of the present invention, Figure 1-Figure 3 As shown, in a projection on a plane perpendicular to the length of the heat exchanger body 10, the outer wall of the protrusion 1 includes a third linear edge 11, a second arc edge 12, and a fourth linear edge 13, which are connected in sequence. The second avoidance groove 121 is provided on the second arc edge 12. The third linear edge 11 extends linearly forward from top to bottom, the second arc edge 12 is an arc convex toward one side in the thickness direction of the heat exchanger body 10, and the fourth linear edge 13 extends linearly backward from top to bottom. The arc of the second arc edge 12 is tangent to the third linear edge 11, and the arc of the second arc edge 12 is tangent to the straight segment of the fourth linear edge 13. At this time, the transitions of the outer wall of the protrusion 1 are relatively smooth. When the airflow flows through the outer wall of the protrusion 1, it can avoid the airflow from contacting the corners of the outer wall of the protrusion 1, avoiding the airflow from producing a sharp whistle. The space utilization of the heat exchanger body 10 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 1000 and causing water blowing as much as possible, thereby improving the quality of the air conditioner 1000.

[0060] In some embodiments of the present invention, Figure 1 As shown, from front to back (such as Figure 1 In the front-to-back direction (shown in the figure), the shortest distance between the lowest point of the bottom of the groove 2 and the first arc segment 2211 is D1, and the shortest distance between the highest point of the protrusion 1 and the second arc segment 1211 is D2, satisfying the following: D1>D2. It can be understood that the shortest distance between the lowest point of the bottom of the groove 2 and the first arc segment 2211 is greater than the shortest distance between the highest point of the protrusion 1 and the second arc segment 1211. This increases the avoidance distance of the first avoidance groove 221, reduces the distance between the heat exchange tube 30 on the side of the heat exchanger body 10 near the groove 2 and the edge of the heat exchanger body 10, and improves the heat exchange efficiency of the heat exchanger 100.

[0061] Furthermore, 0.2 mm ≤ D2 ≤ 2 mm. It is understandable that the shortest distance D2 between the vertex of the protrusion 1 and the second arc segment 1211 may be 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, or 2 mm. The distance D2 between the midpoint of the second arc edge 12 and the midpoint of the second arc segment 1211 is not less than 0.2 mm, which can ensure that there is a certain distance between the midpoint of the second arc edge 12 and the midpoint of the second arc segment 1211, thereby improving the heat exchange efficiency of the heat exchanger 100; the distance D2 between the midpoint of the second arc edge 12 and the midpoint of the second arc segment 1211 is not greater than 2 mm, which can avoid the distance between the midpoint of the second arc edge 12 and the midpoint of the second arc segment 1211 being too large, thereby avoiding affecting the strength of the heat exchanger body 10.

[0062] Furthermore, 1.5 mm ≤ D1 ≤ 10 mm. The shortest distance D1 between the lowest point of the bottom of the groove 2 and the first arc segment 2211 can be 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, 8.5 mm, 9 mm, 9.5 mm, or 10 mm. The distance D1 between the midpoint of the first arc edge 22 and the midpoint of the first arc segment 2211 is not less than 1.5 mm, which can ensure that there is a certain distance between the midpoint of the first arc edge 22 and the midpoint of the first arc segment 2211, thereby improving the heat exchange efficiency of the heat exchanger 100; the distance D1 between the midpoint of the first arc edge 22 and the midpoint of the first arc segment 2211 is not greater than 10 mm, which can avoid the distance between the midpoint of the first arc edge 22 and the midpoint of the first arc segment 2211 being too large, thereby avoiding affecting the strength of the heat exchanger body 10.

[0063] In some embodiments of the present invention, Figure 1-Figure 3 As shown, in a projection of a plane perpendicular to the length of the heat exchanger body 10, the bottom wall of the second avoidance groove 121 also includes a third straight segment 1212 and a fourth straight segment 1213 connecting the two ends of the second arc segment 1211. It is understood that the third straight segment 1212 can be a single straight segment or multiple straight segments, and the fourth straight segment 1213 can be a single straight segment or multiple straight segments. The third straight segment 1212 and the fourth straight segment 1213 facilitate a smooth connection between the second arc segment 1211 and the sidewall of the second avoidance groove 121, avoiding any sharp corners or unevenness within the second avoidance groove 121, and preventing the airflow from producing a sharp whistling sound.

[0064] It is understood that the third straight line segment 1212 is a single straight line segment, which facilitates the processing of the second avoidance groove 121. The third straight line segment 1212 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 1213 is a single straight line segment, which facilitates the processing of the second avoidance groove 121. The fourth straight line segment 1213 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.

[0065] In some embodiments of the present invention, Figure 1 As shown, the heat exchanger body 10 includes a plurality of fins 20 spaced apart along the length of the heat exchanger body 10. The fins 20 are provided with a first notch on one side of the heat exchanger body 10 in the thickness direction. The plurality of first notches together form a first avoidance groove 221, allowing the first avoidance groove 221 to penetrate the groove 2 of the heat exchanger body 10. The fins 20 are provided with a second notch on the other side of the heat exchanger body 10 in the thickness direction. The plurality of second notches together form a second avoidance groove 121, allowing the second avoidance groove 121 to penetrate the protrusion 1 of the heat exchanger body 10. This allows the plurality of fins 20 to avoid other components of the air conditioner 1000, increasing the versatility of the heat exchanger 100 and reducing the material consumption of the heat exchanger body 10.

[0066] In some embodiments of the present invention, Figure 1 As shown, the heat exchanger body 10 includes a plurality of fins 20 spaced apart along the length direction of the heat exchanger body 10 and a plurality of heat exchange tubes 30 extending along the length direction of the heat exchanger body 10. The plurality of heat exchange tubes 30 penetrate the fins 20, and heat exchange medium flows in the heat exchange tubes 30. The inner wall of the groove 2 includes a first inner wall, a second inner wall and a third inner wall connected in sequence. The first avoidance groove 221 is provided on the second inner wall. The minimum distance between the first inner wall and the adjacent heat exchange tube 30 is L1, the minimum distance between the bottom surface of the first avoidance groove 221 and the adjacent heat exchange tube 30 is L2, and the minimum distance between the third inner wall and the adjacent heat exchange tube 30 is L3, wherein L1>L2, L3>L2.

[0067] It can be understood that the minimum distance between the first inner wall and the adjacent heat exchange tube 30 is greater than the minimum distance between the bottom surface of the first avoidance groove 221 and the adjacent heat exchange tube 30, so that the distance between the bottom surface of the first avoidance groove 221 and the adjacent heat exchange tube 30 is smaller, which can reduce the distance between the heat exchange tube 30 on the side of the heat exchanger body 10 close to the groove 2 and the edge of the heat exchanger body 10, thereby improving the heat exchange efficiency of the heat exchanger 100; and can avoid other components in the air conditioner 1000, increase the versatility of the heat exchanger 100, and reduce the material usage of the heat exchanger 100.

[0068] It can be understood that the minimum distance between the third inner wall and the adjacent heat exchange tube 30 is greater than the minimum distance between the bottom surface of the first avoidance groove 221 and the adjacent heat exchange tube 30, so that the distance between the bottom surface of the first avoidance groove 221 and the adjacent heat exchange tube 30 is smaller, which can reduce the distance between the heat exchange tube 30 on the side of the heat exchanger body 10 close to the groove 2 and the edge of the heat exchanger body 10, and improve the heat exchange efficiency of the heat exchanger 100; and can avoid other components in the air conditioner 1000, increase the versatility of the heat exchanger 100, and reduce the material usage of the heat exchanger 100.

[0069] In some embodiments of the present invention, Figure 1 As shown, the distance between the upper edge of the first avoidance groove 221 and the lower edge of the first avoidance groove 221 is H1,60mm

[0070] In some embodiments of the present invention, Figure 1 ​As shown, the minimum distance between the line connecting the upper edge of the first avoidance groove 221 and the lower edge of the first avoidance groove 221 and the bottom surface of the first avoidance groove 221 is H2, 15mm

[0071] The heat exchanger 100 according to the above embodiment is used in an air conditioner 1000. The comparison between the heat exchanger 100 and the conventional air conditioner 1000 under standard working conditions (cooling working conditions: temperature 27°C, humidity 19°C) is shown in the following table:

[0072]

[0073] Table 1 Comparison of heat exchange capacity between conventional air conditioners and this embodiment

[0074] This embodiment has a heat exchange capacity substantially equal to that of a conventional air conditioner and has lower wind resistance. It can reduce the distance between the heat exchange tube 30 on the side of the heat exchanger body 10 close to the groove and the edge of the heat exchanger body 10, thereby improving the heat exchange efficiency of the heat exchanger 100.

[0075] The air conditioner 1000 according to the embodiment of the present invention includes a housing 300 , a wind wheel 200 and a heat exchanger 100 .

[0076] Specifically, if Figure 4 ​As shown, the impeller 200 is disposed within the housing 300, and the heat exchanger 100 is disposed within the housing 300. The heat exchanger 100 is disposed on the outlet side of the impeller 200. The housing 300 is provided with an air inlet 301 and an air outlet 302. Driven by the impeller 200, airflow from outside the air conditioner 1000 enters the housing 300 of the air conditioner 1000 through the air inlet 301. The airflow within the housing 300 flows through the heat exchanger 100 and exchanges heat with the heat exchanger 100. The airflow after heat exchange is blown out through the air outlet 302. Along the airflow direction, the heat exchanger 100 is disposed on the outlet side of the impeller 200 to facilitate heat exchange between the air entering the air conditioner 1000 and the refrigerant within the heat exchanger 100. The air outlet of the impeller 200 faces the first avoidance slot 221.

[0077] 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 1000, protecting the safety of the user and ensuring the normal operation of the air conditioner 1000; on the other hand, the air inlet grille can prevent insects, mice, etc. from entering the shell 300 of the air conditioner 1000 and causing damage to the air conditioner 1000, thereby ensuring the normal operation of the air conditioner 1000 and ensuring the beautiful appearance of the air conditioner 1000.

[0078] Optionally, the air inlet grille is detachably connected to the shell 300. The air inlet grille can ensure the beautiful appearance of the shell 300. After the air inlet grille is removed, it is convenient to repair and replace components inside the air conditioner 1000. 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.

[0079] According to the air conditioner 1000 of the embodiment of the present invention, a first avoidance groove 221 is provided at the bottom of the groove 2 on one side of the thickness direction of the heat exchanger body 10. The first avoidance groove 221 extends along the length direction of the heat exchanger body 10, thereby reducing the distance between the heat exchange tube 30 on the side of the heat exchanger body 10 close to the groove 2 and the edge of the heat exchanger body 10, thereby improving the heat exchange efficiency of the heat exchanger 100; and avoiding other components in the air conditioner 1000, thereby increasing the versatility of the heat exchanger 100 and reducing the material usage of the heat exchanger 100.

[0080] In this embodiment, the air conditioner 1000 is a ducted air conditioner that can be hidden in the ceiling and does not occupy indoor space. It has the advantages of flexible installation, space saving, and uniform air circulation.

[0081] In some embodiments of the present invention, Figure 4As shown, the length direction of the heat exchanger 100 is the same as the axial direction of the wind wheel 200. In the projection within a plane perpendicular to the length direction of the heat exchanger body 10, the heat exchanger body 10 is curved and convex toward the side away from the wind wheel 200. This can increase the size of the heat exchange area of ​​the heat exchanger body 10, thereby improving the heat exchange effect of the heat exchanger 100. Furthermore, along the direction of airflow, the angle at which the airflow contacts the heat exchanger body 10 can be reduced, thus preventing the airflow from producing a sharp whistling sound. The space utilization of the heat exchanger body 10 is better, which can reduce the problem of water accumulation at the outer corners of the bends. This can minimize the possibility of accumulated water dripping into the air duct of the air conditioner 1000 and causing water blowing, thereby improving the quality of the air conditioner 1000.

[0082] Other structures and operations of the heat exchanger 100 and the air conditioner 1000 having the same according to the embodiment of the present invention are well known to those skilled in the art and will not be described in detail here.
