[0002] In the related art, the input and output pipes of the heat exchanger are usually fixed and clamped on the rear side wall of the water receiving tray to fix the input and output pipes of the heat exchanger and prevent the input and output pipes of the heat exchanger from being deformed or even damaged during transportation.

[0003] When assembling a heat exchanger, heat exchanger bracket, and water collection pan, for example, when installing a heat exchanger for a vertical air conditioner, the heat exchanger is usually placed horizontally with the fixed clamping structure for the input and output pipes located on the bottom. The heat exchanger is first installed on the heat exchanger bracket, and then the water collection pan is installed. During the installation of the heat exchanger to the heat exchanger bracket, the fixed clamping structure for the input and output pipes is located on the bottom surface, making it impossible to fix the input and output pipes. The heat exchanger needs to be flipped 180 degrees up and down, so that the fixed clamping structure located on the input and output pipes is flipped from the bottom surface to the top surface, and finally the input and output pipes of the heat exchanger are fixed. The assembly steps are cumbersome and the assembly efficiency is low. Therefore, there is room for improvement. Utility Model Content

[0052] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0053] Reference below Figures 1-12 A heat exchanger assembly and an air conditioner according to embodiments of the present invention are described.

[0054] According to the heat exchanger assembly 10 of the first embodiment of the present invention, Figure 3 , including: a heat exchanger component 20, an input and output pipe 40 and a pressure pipe part 50.

[0055] The heat exchanger component 20 includes a heat exchanger bracket 22 and a heat exchanger 21. The heat exchanger 21 is mounted on the heat exchanger bracket 22. The heat exchanger component 20 has a first side 23 and a second side 24 that are opposite to each other along a first direction (e.g., direction e1 in the drawings). The first direction is perpendicular to the vertical direction. The heat exchanger bracket 22 has a mounting flange 25 for mounting and securing the heat exchanger 21. The mounting flange 25 is located on the first side 23 of the heat exchanger component 20. The first side 23 and the second side 24 that are opposite to each other along the first direction of the heat exchanger component 20 refer to the placement orientation of the air conditioner during normal use.

[0056] For example, the heat exchanger component 20 may be U-shaped, the open side of the heat exchanger component 20 may be the first side 23 of the heat exchanger component 20 , and the back side of the heat exchanger component 20 may be the second side 24 of the heat exchanger component 20 .

[0057] The input and output pipes 40 are connected to the first side 23 of the heat exchanger component 20 and connected to the heat exchanger 21 .

[0058] The pipe pressing member 50 is mounted on the bottom surface of the heat exchanger bracket 22 and defines a clamping space 51 with the bottom surface of the heat exchanger bracket 22. The input and output pipes 40 are passed through the clamping space 51. By defining the clamping space 51 between the pipe pressing member 50 and the bottom surface of the heat exchanger bracket 22 and passing the input and output pipes 40 through the clamping space 51, the pipe pressing member 50 can limit the input and output pipes 40, preventing them from moving inside the air conditioner and interfering with other components. In addition, the connection between the input and output pipes 40 and the heat exchanger bracket 22 can be tightened. When personnel grasp the input and output pipes 40 of the heat exchanger 21 to lift and carry the heat exchanger 21, the input and output pipes 40 are not easily detached from the heat exchanger bracket 22. Furthermore, direct connection between the input and output pipes 40 and the fins of the heat exchanger 21 can be avoided, thereby preventing the fins of the heat exchanger 21 from being damaged.

[0059] When assembling the heat exchanger component 20, the heat exchanger bracket 22 and heat exchanger 21 are placed flat, with the pipe crimping fitting 50 installed on the side of the heat exchanger bracket 22. The heat exchanger 21 is then connected and secured to the heat exchanger bracket 22. Subsequently, the input and output pipes 40 are installed directly on the side of the heat exchanger bracket 22 without changing the orientation of the heat exchanger 21 and the heat exchanger bracket 22, and the pipe crimping fitting 50 is used to secure the pipes. This reduces the number of assembly steps for the heat exchanger assembly 10 and improves assembly efficiency.

[0060] For example, the heat exchanger component 20 is U-shaped. When assembling the heat exchanger component 20, the heat exchanger bracket 22 and the heat exchanger 21 are placed flat, with the open end of the heat exchanger component 20 facing upward. The pipe crimping fitting 50 is then installed on the side of the heat exchanger bracket 22. After the heat exchanger 21 is connected and fixed to the heat exchanger bracket 22, the input and output pipes 40 are then installed directly on the side of the heat exchanger bracket 22 without changing the orientation of the heat exchanger 21 and the heat exchanger bracket 22. This reduces the number of assembly steps for the heat exchanger assembly 10 and improves assembly efficiency.

[0061] According to the heat exchanger assembly 10 of the embodiment of the present invention, by arranging the pressing pipe fitting 50 on the bottom surface of the heat exchanger bracket 22, when the heat exchanger bracket 22 is placed horizontally to install the heat exchanger 21, the position on the heat exchanger bracket 22 that is connected to the pressing pipe fitting 50 is located on the side of the heat exchanger bracket 22. When installing the input and output pipes 40 of the heat exchanger 21, there is no need to turn the heat exchanger 21 upside down to achieve the fixing operation of the input and output pipes 40, thereby reducing the assembly steps and improving the assembly efficiency of the heat exchanger assembly 10; and, the heat exchanger 21 and the input and output pipes 40 that are fixed and clamped to the heat exchanger 21 can be installed at the same time, which can effectively improve the assembly efficiency of the heat exchanger assembly 10.

[0062] According to some embodiments of the present invention, referring to Figure 4-Figure 6The input and output pipes 40 include a first tube bundle section 41, a second tube bundle section 42, and a third tube bundle section 43, which are connected in sequence. The first tube bundle section 41 is connected to the heat exchanger 21 and is located on the first side 23 of the heat exchanger component 20. The first tube bundle section 41 extends in the vertical direction, while the second tube bundle section 42 extends from the first side 23 to the second side 24 of the heat exchanger component 20. At least a portion of the second tube bundle section 42 is located below the heat exchanger support 22 and passes through the clamping space 51. By extending the first tube bundle section 41 in the vertical direction and the second tube bundle section 42 from the first side 23 to the second side 24 of the heat exchanger component 20, the routing of the first and second tube bundle sections 41, 42 is more convenient.

[0063] According to some embodiments of the present invention, referring to Figure 4-Figure 6 The input and output pipes 40 include a third tube bundle segment 43, which is connected to the end of the second tube bundle segment 42 that is distal from the first tube bundle segment 41 and extends downward. This downwardly extending third tube bundle segment 43 allows the input and output pipes 40 to extend downward to a suitable position, facilitating connection between the input and output pipes 40 and corresponding components. For example, if the heat exchanger assembly 10 includes a water tray 60, at least a portion of the third tube bundle segment 43 is located below the water tray 60.

[0064] According to some embodiments of the present invention, referring to Figure 3-Figure 6 The heat exchanger assembly 10 includes a water pan 60, which is located below the heat exchanger component 20. The second tube bundle segment 42 is located above the water pan 60. By including the water pan 60 in the heat exchanger assembly 10, water dripping from the heat exchanger component 20 will fall into the water pan 60. By positioning the second tube bundle segment 42 above the water pan 60, water dripping from the second tube bundle segment 42 can be collected in the water pan 60. This prevents water from dripping onto other components within the air conditioner and affecting safety, thereby improving the safety of the air conditioner.

[0065] According to some embodiments of the present invention, referring to Figure 7 and Figure 8The second tube bundle section 42 includes an inclined tube section 44. The angle between the central axis of the inclined tube section 44 and the horizontal direction is greater than zero. The central axis of the inclined tube section 44 extends obliquely downward in the direction from the second side 24 to the first side 23 of the heat exchanger component 20. By including the inclined tube section 44 in the second tube bundle section 42, when water droplets form on the second tube bundle section 42, the water droplets are attracted to the lower part of the inclined tube section 44 due to their own gravity. The water droplets on the second tube bundle section 42 fall near the lowest point, making them easier to collect. By extending the central axis of the inclined tube section 44 obliquely downward in the direction from the second side 24 to the first side 23 of the heat exchanger component 20, the water on the inclined tube section 44 can flow and converge along the inclined tube section 44 and toward the connection between the second tube bundle section 42 and the first tube bundle section 41 under the action of its own gravity, so that the water on the second tube bundle section 42 drips into the water receiving tray 60 as much as possible, preventing the water on the second tube bundle section 42 from flowing along the extension direction of the input and output pipes 40 and dripping onto other components of the air conditioner, for example, preventing the water on the second tube bundle section 42 from flowing along the second tube bundle section 42 to the third tube bundle section 43 and dripping onto other components of the air conditioner.

[0066] According to some embodiments of the present invention, referring to Figure 7 The angle between the central axis of the inclined pipe section 44 and the horizontal direction is a, 2°≤a≤6°. For example, the value of a can be 2°, 3°, 4°, 5°, 6°, etc. By making the angle a between the central axis of the inclined pipe section 44 and the horizontal direction not less than 2°, the inclined pipe section 44 can more effectively guide and converge the water droplets on the inclined pipe section 44. When there are water droplets on the second tube bundle section 42, the water droplets can be gathered at the lower part of the inclined pipe section 44 due to their own gravity, so that the water droplets on the second tube bundle section 42 fall near the lowest point, which is convenient for collection. By making the angle a between the central axis of the inclined pipe section 44 and the horizontal direction not greater than 6°, it is possible to avoid the second tube bundle section 42 from being tilted too much, resulting in the second tube bundle section 42 being too far apart in the vertical direction, thereby avoiding increasing the vertical length of the air conditioner.

[0067] According to some embodiments of the present invention, referring to Figure 4-Figure 6 The oblique pipe section 44 is covered with a cut-off sleeve 46. The cut-off sleeve 46 is covered with the oblique pipe section 44. The cut-off sleeve 46 has a larger diameter than the oblique pipe section 44, which prevents water droplets on the oblique pipe section 44 from flowing along the extension direction of the input and output pipes 40 and dripping onto other components of the air conditioner. For example, the cut-off sleeve 46 can prevent water on the oblique pipe section 44 from flowing along the second tube bundle section 42 to the third tube bundle section 43 and dripping onto other components of the air conditioner.

[0068] According to some embodiments of the present invention, the intercepting sleeve 46 is a rubber sleeve. This facilitates assembly of the intercepting sleeve 46 with the oblique pipe section 44. The flexibility and elasticity of the rubber sleeve allow for an interference fit between the intercepting sleeve 46 and the oblique pipe section 44, resulting in a better seal between the intercepting sleeve 46 and the oblique pipe section 44. This better prevents water droplets on the oblique pipe section 44 from flowing along the extension direction of the input and output pipes 40 and dripping onto other components of the air conditioner. It also prevents the intercepting sleeve 46 from rusting and corroding, which could render the intercepting sleeve 46 ineffective.

[0069] According to some embodiments of the present invention, referring to Figure 6-Figure 8 The second tube bundle segment 42 includes a straight tube segment 45, which is inserted into the clamping space 51. The angle between the central axis of the straight tube segment 45 and the horizontal direction is smaller than the angle between the central axis of the oblique tube segment 44 and the horizontal direction. By making the angle between the central axis of the straight tube segment 45 and the horizontal direction smaller than the angle between the central axis of the oblique tube segment 44 and the horizontal direction, the straight tube segment 45 can be more easily connected to the compression clamp. For example, the straight tube segment 45 is connected between the third tube bundle segment 43 and the oblique tube segment 44.

[0070] According to some embodiments of the present invention, referring to Figure 6-Figure 8 The angle between the central axis of the straight pipe section 45 and the horizontal direction is zero. By setting the angle between the central axis of the straight pipe section 45 and the horizontal direction to zero, the fit between the straight pipe section 45 and the pipe clamp is more stable and sufficient, making the connection between the straight pipe section 45 and the heat exchanger bracket 22 more stable.

[0071] According to some embodiments of the present invention, referring to Figure 6-Figure 8 The straight pipe section 45 is covered with a heat-insulating layer 47. By providing the heat-insulating layer 47 on the straight pipe section 45, the heat exchange between the refrigerant in the pipe and the air can be reduced, thereby improving the heat exchange efficiency of the heat exchanger 21.

[0072] According to some embodiments of the present invention, referring to Figure 6-Figure 8 The second tube bundle segment 42 includes an oblique tube segment 44. The angle between the central axis of the oblique tube segment 44 and the first direction is greater than zero. In the direction from the first side 23 to the second side 24 of the heat exchanger component 20, the central axis of the oblique tube segment 44 extends obliquely toward a direction near the center of the heat exchanger component 20 in the second direction (e.g., direction e2 in the drawings). The second direction, the first direction, and the vertical direction are perpendicular to each other. By obliquely extending the central axis of the oblique tube segment 44 toward a direction near the center of the heat exchanger component 20 in the second direction, the second tube bundle segment 42 is prevented from interfering with other fixed structures, such as the heat exchanger bracket 22, the heat exchanger 21, and the casing, thereby facilitating connection of the oblique tube segment 44 with the third tube bundle segment 43.

[0073] According to some embodiments of the present invention, referring to Figure 6-Figure 8 The angle b between the central axis of the inclined pipe section 44 and the first direction is 20°≤b≤40°. For example, the angle b between the central axis of the inclined pipe section 44 and the first direction can be 20°, 25°, 30°, 35°, 40°, etc. By setting the value of b within the range of 20°≤b≤40°, the inclined pipe section 44 can be easily connected to the straight pipe section 45.

[0074] According to some embodiments of the present invention, referring to Figure 6 The lower end of the heat exchanger support 22 is provided with an avoidance groove 26, and the lower end of the first tube bundle segment 41 is accommodated in the avoidance groove 26. By providing the avoidance groove 26 at the lower end of the heat exchanger support 22 and accommodating the lower end of the first tube bundle segment 41 in the avoidance groove 26, interference between the first tube bundle segment 41 and the heat exchanger support 22 can be avoided.

[0075] According to some embodiments of the present invention, the input and output pipes 40 include a third pipe bundle segment 43, which is connected to the end of the second pipe bundle segment 42 away from the first pipe bundle segment 41 and extends downward. By including the third pipe bundle segment 43 and extending downward, the input and output pipes 40 can be easily connected to other components. For example, if the air conditioner is a split-type air conditioner, the air conditioner includes an indoor unit 100 and an outdoor unit, and the indoor unit 100 includes the heat exchanger assembly 10 according to an embodiment of the present invention, by including the third pipe bundle segment 43 and extending downward, the input and output pipes 40 can be easily extended outside the indoor unit 100 and connected to the outdoor unit.

[0076] According to some embodiments of the present invention, the pipe pressing member 50 is detachably connected to the heat exchanger support 22. This detachable connection between the pipe pressing member 50 and the heat exchanger support 22 facilitates installation of the input and output pipes 40. For example, the pipe pressing member 50 can be removed first, the second tube bundle section 42 can be pre-installed on the heat exchanger support 22, and then the pipe pressing member 50 can be fixed to the heat exchanger support 22 to secure the second tube bundle section 42 to the heat exchanger support 22.

[0077] According to some embodiments of the present invention, referring to Figures 9-11The bottom surface of the heat exchanger support 22 is provided with a mounting groove 27, a first fixing portion 28, and a second fixing portion 29. The first fixing portion 28 and the second fixing portion 29 are located on opposite sides of the mounting groove 27. The pipe pressing member 50 includes a pipe pressing plate 52, a first connecting plate 53, and a second connecting plate 54. The first connecting plate 53 and the second connecting plate 54 are connected to opposite sides of the pipe pressing plate 52. The pipe pressing plate 52 and the inner wall of the mounting groove 27 jointly define a clamping space 51. The first connecting plate 53 is connected to the first fixing portion 28, and the second connecting portion is connected to the second fixing portion 29. By making the pipe pressing member 50 include the pipe pressing plate 52, the first connecting plate 53, and the second connecting plate 54, the pipe pressing member 50 can be easily connected to the heat exchanger support 22. By connecting the first connecting plate 53 to the first fixing portion 28 and the second connecting portion to the second fixing portion 29, the connection between the pipe pressing member 50 and the heat exchanger support 22 can be made more secure.

[0078] According to some embodiments of the present invention, referring to Figure 9 The first connecting plate 53 is connected to the first fixing portion 28 via a fastener, and the second connecting plate 54 is connected to the second fixing portion 29 by a snap connection. By fastening the first connecting plate 53 to the first fixing portion 28 and snapping the second connecting plate 54 to the second fixing portion 29, the connection between the first connecting plate 53 and the first fixing portion 28 can be more secure, and the assembly and disassembly between the second connecting plate 54 and the second fixing portion 29 can be more convenient. For example, the fastener can be a screw.

[0079] According to some embodiments of the present invention, referring to Figure 9 and Figure 12 The first fixing portion 28 is provided with a limiting rib 31, which is located on the outer periphery of the first connecting plate 53. The first fixing portion 28 is provided with the limiting rib 31, which allows the limiting rib 31 to limit the first connecting plate 53 in the first direction, preventing the compression fitting 50 from moving in the first direction and causing it to become unfastened from the heat exchanger bracket 22.
