Abstract
Description
Technical Field
[0001] This invention relates to the field of air conditioning, and more particularly to a heat exchanger assembly and an air conditioner. Background Technology
[0002] In related technologies, the input and output pipes of the heat exchanger are usually fixedly clamped to the rear side wall of the water receiving tray to fix the input and output pipes of the heat exchanger and prevent deformation or even damage to the input and output pipes of the heat exchanger during transportation.
[0003] When assembling heat exchangers, heat exchanger brackets, and drip trays, such as when installing the heat exchanger in a vertical air conditioner, the heat exchanger is usually laid horizontally with the inlet and outlet pipe clamping structures located on the bottom. First, the heat exchanger is installed on the heat exchanger bracket, and then the drip tray is installed. However, during the installation of the heat exchanger onto the bracket, because the inlet and outlet pipe clamping structures are located on the bottom, the pipes cannot be properly secured. The heat exchanger needs to be rotated 180° vertically to bring the clamping structures from the bottom to the top before finally securing the pipes. This assembly process is cumbersome and inefficient. Therefore, improvements are needed. Summary of the Invention

Therefore, one object of this invention is to provide a heat exchanger assembly in which a pressure fitting is disposed on the bottom surface of a heat exchanger support. When the heat exchanger support is laid horizontally for heat exchanger installation, the connection point between the pressure fitting and the heat exchanger support is located on the side of the heat exchanger support. This eliminates the need to flip the heat exchanger over during the installation of the heat exchanger's input and output pipes, reducing assembly steps and improving the assembly efficiency of the heat exchanger assembly. Furthermore, the heat exchanger and the input and output pipes that hold the heat exchanger can be installed and fixed simultaneously, effectively improving the assembly efficiency of the heat exchanger assembly.

[0052] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0053] The following is for reference. Figures 1-12 A heat exchanger assembly and an air conditioner according to embodiments of the present invention are described.
[0054] According to a first aspect embodiment of the heat exchanger assembly 10, referring to Figure 3 It includes: heat exchanger component 20, inlet and outlet pipes 40 and pressure pipe fitting 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 each other along a first direction (e.g., direction e1 in the figure). The first direction is perpendicular to the vertical direction. The heat exchanger bracket 22 has a mounting flange 25 for mounting and fixing 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 each other along the first direction are relative to the placement direction of the air conditioner during normal use.
[0056] For example, the heat exchanger component 20 can be U-shaped, with the open side of the heat exchanger component 20 being the first side 23 and the back side of the heat exchanger component 20 being the second side 24.
[0057] The input / output pipe 40 is connected to the first side 23 of the heat exchanger component 20 and is connected to the heat exchanger 21.
[0058] The pressure fitting 50 is installed 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 pass through the clamping space 51. By defining the clamping space 51 with the bottom surface of the heat exchanger bracket 22, and by having the input and output pipes 40 pass through the clamping space 51, the pressure fitting 50 can limit the input and output pipes 40, preventing them from moving inside the air conditioner and interfering with other components. Furthermore, it can make the connection between the input and output pipes 40 and the heat exchanger bracket 22 more secure. When personnel grasp the input and output pipes 40 of the heat exchanger 21 to lift and move the heat exchanger 21, the input and output pipes 40 are less likely to fall off the heat exchanger bracket 22. It can also prevent the input and output pipes 40 from directly connecting to the fins of the heat exchanger 21, thus avoiding damage to the fins of the heat exchanger 21.
[0059] When assembling the heat exchanger component 20, the heat exchanger bracket 22 and the heat exchanger 21 are laid flat, with the pressure fitting 50 positioned on the side of the heat exchanger bracket 22. The heat exchanger 21 is then connected and fixed to the heat exchanger bracket 22. Subsequently, without changing the orientation of the heat exchanger 21 and the heat exchanger bracket 22, the inlet and outlet pipes 40 are directly installed on the side of the heat exchanger bracket 22 and fixed using the pressure fitting 50. This reduces the number of assembly steps for the heat exchanger assembly 10, resulting in higher assembly efficiency.
[0060] For example, heat exchanger component 20 is U-shaped. During assembly, the heat exchanger support 22 and heat exchanger 21 are laid flat with the open end of heat exchanger component 20 facing upwards. The pressure fitting 50 is then positioned on the side of the heat exchanger support 22. The heat exchanger 21 is connected and fixed to the heat exchanger support 22. Subsequently, without changing the orientation of the heat exchanger 21 and heat exchanger support 22, the inlet and outlet pipes 40 are directly installed on the side of the heat exchanger support 22 and fixed using the pressure fitting 50. This reduces the number of assembly steps for the heat exchanger assembly 10, resulting in higher assembly efficiency.
[0061] According to the embodiment of the present invention, the heat exchanger assembly 10, by setting the pressure fitting 50 on the bottom surface of the heat exchanger bracket 22, when the heat exchanger bracket 22 is laid horizontally to install the heat exchanger 21, the position on the heat exchanger bracket 22 that connects and cooperates with the pressure 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, the input and output pipes 40 can be fixed without flipping the heat exchanger 21 up and down, reducing assembly steps and improving the assembly efficiency of the heat exchanger assembly 10. Furthermore, the heat exchanger 21 and the input and output pipes 40 of the heat exchanger 21 can be installed and fixed simultaneously, which can effectively improve the assembly efficiency of the heat exchanger assembly 10.
[0062] According to some embodiments of the present invention, with reference to Figures 4-6 The input / output pipe 40 includes a first tube bundle section 41, a second tube bundle section 42, and a third tube bundle section 43 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 vertically, and 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 making the first tube bundle section 41 extend vertically and the second tube bundle section 42 extend from the first side 23 to the second side 24 of the heat exchanger component 20, the routing of the first tube bundle section 41 and the second tube bundle section 42 can be made more convenient.
[0063] According to some embodiments of the present invention, with reference to Figures 4-6 The input / output pipe 40 includes a third tube bundle section 43, which is connected to the end of the second tube bundle section 42 away from the first tube bundle section 41, and extends downward. By providing the downwardly extending third tube bundle section 43, the input / output pipe 40 extends downward to a suitable position to facilitate connection between the input / output pipe 40 and corresponding components. For example, when the heat exchanger assembly 10 includes a water receiving pan 60, at least a portion of the third tube bundle section 43 is located below the water receiving pan 60.
[0064] According to some embodiments of the present invention, with reference to Figures 3-6The heat exchanger assembly 10 includes a water collection tray 60 located below the heat exchanger component 20, and a second tube bundle section 42 located above the water collection tray 60. By including the water collection tray 60 in the heat exchanger assembly 10, water dripping from the heat exchanger component 20 will fall into the water collection tray 60. By positioning the second tube bundle section 42 above the water collection tray 60, water on the second tube bundle section 42 can drip into the water collection tray 60 for collection, preventing water on the second tube bundle section 42 from dripping onto other components inside the air conditioner and affecting safety, thus improving the safety of the air conditioner.
[0065] According to some embodiments of the present invention, with reference to Figure 7 and Figure 8 The 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 being greater than zero. The central axis of the inclined tube section 44 extends downwards at an angle 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 there are water droplets on the second tube bundle section 42, the water droplets can collect at the lower part of the inclined tube section 44 due to their own gravity, making it easier to collect the water droplets near the lowest point. By making the central axis of the inclined tube section 44 extend downwards 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 under its own gravity and toward the connection between the second tube bundle section 42 and the first tube bundle section 41. This allows the water on the second tube bundle section 42 to drip 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, it prevents 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, with reference to Figure 7 The angle between the central axis of the inclined tube segment 44 and the horizontal direction is α, where 2° ≤ α ≤ 6°. For example, the value of α can be 2°, 3°, 4°, 5°, 6°, etc. By ensuring that the angle α between the central axis of the inclined tube segment 44 and the horizontal direction is not less than 2°, the guiding and converging effect of the water droplets on the inclined tube segment 44 can be more effective. When there are water droplets on the second tube bundle segment 42, the water droplets can be drawn to the lower part of the inclined tube segment 44 by their own gravity, so that the water droplets on the second tube bundle segment 42 fall near the lowest point, making them easier to collect. By ensuring that the angle α between the central axis of the inclined tube segment 44 and the horizontal direction is not greater than 6°, the excessive tilt angle of the second tube bundle segment 42 can be avoided, which would result in an excessively large vertical distance between the second tube bundle segment 42 and the vertical length of the air conditioner.
[0067] According to some embodiments of the present invention, with reference to Figures 4-6 A flow-blocking sleeve 46 is fitted onto the inclined tube section 44. By fitting the flow-blocking sleeve 46 onto the inclined tube section 44, the diameter of the flow-blocking sleeve 46 is larger than that of the inclined tube section 44, preventing water droplets on the inclined tube section 44 from flowing along the extension direction of the input / output pipe 40 and dripping onto other components of the air conditioner. For example, the flow-blocking sleeve 46 can prevent water on the inclined tube 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 flow-blocking sleeve 46 is a rubber sleeve. By making the flow-blocking sleeve 46 a rubber sleeve, it is convenient to assemble the flow-blocking sleeve 46 with the inclined pipe section 44. Utilizing the flexibility and elasticity of the rubber sleeve, the flow-blocking sleeve 46 and the inclined pipe section 44 can be interference-fitted, thereby making the sealing performance of the fit between the flow-blocking sleeve 46 and the inclined pipe section 44 better. This can better prevent water droplets on the inclined pipe section 44 from flowing along the extension direction of the input and output pipes 40 and dripping onto other parts of the air conditioner. It can also prevent the flow-blocking sleeve 46 from rusting and corroding, which would cause the flow-blocking function of the flow-blocking sleeve 46 to fail.
[0069] According to some embodiments of the present invention, with reference to Figures 6-8 The second tube bundle section 42 includes a straight tube section 45, which passes through the clamping space 51. The angle between the central axis of the straight tube section 45 and the horizontal direction is smaller than the angle between the central axis of the inclined tube section 44 and the horizontal direction. By making the angle between the central axis of the straight tube section 45 and the horizontal direction smaller than the angle between the central axis of the inclined tube section 44 and the horizontal direction, the straight tube section 45 can be more easily connected with the clamp. For example, the straight tube section 45 is connected between the third tube bundle section 43 and the inclined tube section 44.
[0070] According to some embodiments of the present invention, with reference to Figures 6-8 The angle between the central axis of the straight pipe section 45 and the horizontal direction is zero. By making the angle between the central axis of the straight pipe section 45 and the horizontal direction zero, the fit between the straight pipe section 45 and the pressure clamp can be made more stable and sufficient, and the connection between the straight pipe section 45 and the heat exchanger support 22 can be made more stable.
[0071] According to some embodiments of the present invention, with reference to Figures 6-8 The straight pipe section 45 is covered with an insulation layer 47. By providing an insulation layer 47 on the straight pipe section 45, the heat exchange between the refrigerant and the air inside the pipe can be reduced, thereby improving the heat exchange efficiency of the heat exchanger 21.
[0072] According to some embodiments of the present invention, with reference to Figures 6-8The 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 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 inclined tube section 44 extends obliquely toward a position close to the middle of the heat exchanger component 20 in the second direction (e.g., direction e2 in the figure). The second direction, the first direction, and the up-down direction are perpendicular to each other. By extending the central axis of the inclined tube section 44 obliquely toward a position close to the middle of the heat exchanger component 20 in the second direction, interference between the second tube bundle section 42 and other fixed structures, such as the fixed structures of the heat exchanger support 22, the heat exchanger 21, and the casing, can be avoided. This also facilitates the connection of the inclined tube section 44 to the third tube bundle section 43.
[0073] According to some embodiments of the present invention, with reference to Figures 6-8 The angle between the central axis of the inclined pipe section 44 and the first direction is denoted by b, and the value of b ranges from 20° to 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 ensuring that the value of b is within the range of 20° to 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, with reference to Figure 6 The lower end of the heat exchanger support 22 is provided with a relief groove 26, and the lower end of the first tube bundle section 41 is accommodated in the relief groove 26. By providing a relief groove 26 at the lower end of the heat exchanger support 22 and accommodating the lower end of the first tube bundle section 41 in the relief groove 26, interference between the first tube bundle section 41 and the heat exchanger support 22 can be avoided.
[0075] According to some embodiments of the present invention, the input / output pipe 40 includes a third tube bundle segment 43, which is connected to the end of the second tube bundle segment 42 away from the first tube bundle segment 41, and extends downward. By including the third tube bundle segment 43 in the input / output pipe 40 and having the third tube bundle segment 43 extend downward, the input / output pipe 40 can be easily connected to other components. For example, in a split-type air conditioner, the air conditioner includes an indoor unit 100 and an outdoor unit. The indoor unit 100 includes a heat exchanger assembly 10 according to an embodiment of the present invention. By including the third tube bundle segment 43 in the input / output pipe 40 and having the third tube bundle segment 43 extend downward, the input / output pipe 40 can be easily extended to the outside of the indoor unit 100 and connected to the outdoor unit.
[0076] According to some embodiments of the present invention, the crimp fitting 50 is detachably connected to the heat exchanger support 22. By making the crimp fitting 50 detachably connected to the heat exchanger support 22, the installation of the input and output pipes 40 can be made more convenient. For example, the crimp fitting 50 can be removed first, the second tube bundle section 42 can be pre-installed onto the heat exchanger support 22, and then the crimp fitting 50 can be fixed onto the heat exchanger support 22, thereby fixing the second tube bundle section 42 to the heat exchanger support 22.
[0077] According to some embodiments of the present invention, with reference to Figures 9-11 The bottom surface of the heat exchanger bracket 22 is provided with a mounting groove 27, a first fixing part 28, and a second fixing part 29. The first fixing part 28 and the second fixing part 29 are located on opposite sides of the mounting groove 27. The pressing fitting 50 includes a 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 pressing plate 52. The pressing plate 52 and the inner wall of the mounting groove 27 together define a clamping space 51. The first connecting plate 53 is connected to the first fixing part 28, and the second connecting part is connected to the second fixing part 29. By including a pressing plate 52, a first connecting plate 53, and a second connecting plate 54 in the pressing fitting 50, the pressing fitting 50 can be easily connected to the heat exchanger bracket 22. By connecting the first connecting plate 53 to the first fixing part 28 and the second connecting part to the second fixing part 29, the connection between the pressing fitting 50 and the heat exchanger bracket 22 can be made more secure.
[0078] According to some embodiments of the present invention, with reference to Figure 9 The first connecting plate 53 is connected to the first fixing part 28 by fasteners, and the second connecting plate 54 is snap-fitted to the second fixing part 29. By connecting the first connecting plate 53 to the first fixing part 28 with fasteners and snap-fitting the second connecting plate 54 to the second fixing part 29, the connection between the first connecting plate 53 and the first fixing part 28 can be made more secure, and the assembly and disassembly of the second connecting plate 54 and the second fixing part 29 can be made easier. For example, the fastener can be a screw.
[0079] According to some embodiments of the present invention, with reference to Figure 9 and Figure 12 The first fixing part 28 is provided with a limiting rib 31, which is located on the outer periphery of the first connecting plate 53.
