[0036] In the prior art, after the heat exchanger is installed in the heat exchange box, in order to ensure the stability of the heat exchanger installation, the heat exchanger is fastened in the heat exchange box. However, the space for fixing the heat exchanger in the heat exchange box is small, the operation is inconvenient, the fixing process of the heat exchanger is difficult, and the heat exchanger is easily hit during the fixing process, causing damage to the heat exchanger. The heat exchange assembly and air duct machine provided in the embodiments of the present application can improve the above problems to a certain extent. The heat exchange assembly and air duct machine provided in the embodiments of the present application can facilitate the connection of the heat exchanger with the heat exchange box.

[0037] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0038] The heat exchange assembly and duct unit provided in this embodiment are intended to at least to some extent solve the technical problem of the inconvenience of connecting the heat exchanger to the heat exchange box.

[0039] Figure 1 It is a schematic diagram of the structure of the heat exchange assembly of some embodiments; Figure 2 for Figure 1 A schematic diagram of the structure of the middle heat exchange assembly with the top cover removed; Figure 3 for Figure 1 Structural schematic diagram of the heat exchange assembly with the side panels removed; Figure 6 for Figure 3 Schematic diagram of the structure of the connecting parts; Figure 8 for Figure 6 Side view of the connecting piece. Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 8 The heat exchange assembly of the embodiment of the present application includes: a heat exchange box 10, a heat exchanger 20 and a connector 30. The heat exchanger 20 is disposed in the heat exchange box 10. The connector 30 includes a first connector 301 and a second connector 302 connected to the first connector 301 at an angle, the first connector 301 is detachably connected to the heat exchanger 20, and the second connector 302 is connected to the heat exchange box 10.

[0040] The heat exchanger 20 may be an evaporator.

[0041] Since the heat exchanger 20 is arranged in the heat exchange box 10, the heat exchanger 20 is accommodated by the heat exchange box 10 to protect the heat exchanger 20 and prevent the heat exchanger 20 from being hit by external debris, thereby ensuring the safety of the heat exchanger 20. At the same time, the heat exchanger 20 can also be shielded to ensure the appearance. Since the connecting member 30 includes a first connecting portion 301 and a second connecting portion 302 connected to the first connecting portion 301 at an angle, the first connecting portion 301 is detachably connected to the heat exchanger 20, and the second connecting portion 302 is connected to the heat exchange box 10. Therefore, the first connecting portion 301 is connected to the heat exchanger 20, and the second connecting portion 302 is connected to the heat exchange box 10. The heat exchanger 20 can be connected by The first connection part 301 and the second connection part 302 carry the heat exchanger 20 to support the heat exchanger 20 and ensure the stability of the installation of the heat exchanger 20. At the same time, the second connection part 302 and the heat exchanger 10 can be connected from the outside of the heat exchange box 10 to fix the heat exchanger 20. There is no need to operate inside the heat exchange box 10. There is enough space outside the heat exchange box 10 to facilitate the connection between the second connection part 302 and the heat exchange box 10, which reduces the difficulty of installation, reduces the workload, facilitates operation, and improves work efficiency. Moreover, when operating outside the heat exchange box 10, the heat exchanger 20 will not be touched, thereby avoiding damage to the heat exchanger 20 and ensuring the safety of the heat exchanger 20.

[0042] In some embodiments, since the connector 20 transfers the bearing force of the heat exchanger 20 to the heat exchange box 10 , in order to ensure the structural strength of the connector 20 , the first connector 301 and the second connector 302 may be integrally formed.

[0043] Combination Figure 3 In some embodiments, in order to support the first connection part 301, the heat exchange assembly includes: a support plate 40. The support plate 40 is connected to the heat exchange box 10 and is located in the heat exchange box 10. The first connection part 301 can be placed on the support plate 40. The first connection part 301 is supported by the support plate 40. In the process of connecting the second connection part 302 and the heat exchange box 10, it is not necessary to support the second connection part 302, which reduces the difficulty of installation, reduces the workload, facilitates operation, and improves work efficiency. At the same time, when the first connection part 301 is placed on the support plate 40, the support plate 40 can limit the first connection part 301 in the height direction of the heat exchange box 10 to ensure that the position of the first connection part 301 is accurate, which is convenient for the connection between the second connection part 302 and the heat exchange box 10.

[0044] Combination Figure 1 , Figure 2 and Figure 3 In some embodiments, in order to prevent the support plate 40 from affecting the air outlet, the heat exchange box 10 includes a side plate 101, the support plate 40 is connected to the side plate 101, and is located between the heat exchanger 20 and the side plate 101. That is, along the air outlet direction, the projection of the support plate 40 on the heat exchange box 10 will not overlap with the projection of the heat exchanger 20 on the heat exchange box 10, and the wind passing through the heat exchanger 20 will not be blocked by the support plate 40, thereby ensuring the air outlet volume.

[0045] Combination Figure 6 In some embodiments, the angle between the first connection portion 301 and the second connection portion 302 may be an acute angle, a right angle, or an obtuse angle.

[0046] In some embodiments, in order to facilitate the connection between the first connection part 301 and the heat exchanger 20, and also to facilitate the connection between the second connection part 302 and the heat exchange box body 10, the first connection part 301 can be perpendicular to the second connection part 302, but the vertical relationship between the first connection part 301 and the second connection part 302 is not absolutely vertical in a geometric sense, and the angle relationship between the first connection part 301 and the second connection part 302 can be in the range of 90±3°.

[0047] Figure 4 for Figure 1 Schematic diagram of the connection between the connecting piece of the middle heat exchange component and the side plate; Figure 5 for Figure 4 Side view of the combination Figure 4 and Figure 5In some embodiments, in order to facilitate the connection between the heat exchanger 20 and the connector 30, the heat exchanger 20 includes: a fin component 201, a side plate 202 and a pipe component 203. The side plate 202 includes a third connection portion 2021 connected to the fin component 201 and a fourth connection portion 2022 connected to the third connection portion 2021 at an angle. The pipe component 203 is arranged through the third connection portion 2021 and communicates with the fin component 201. The fourth connection portion 2022 is located below the pipe component 203, and the fourth connection portion 2022 is detachably connected to the first connection portion 301.

[0048] In some embodiments, the third connection part 2021 is connected to the fin component 201, and the fourth connection part 2022 is connected to the first connection part 301. The heat exchange box body 10 can support the fin component 201 through the third connection part 2021, the fourth connection part 2022, the first connection part 301 and the second connection part 302 to support the fin component 201 and ensure the stability of the installation of the fin component 201.

[0049] In some embodiments, the first connection portion 301 may be located between the fourth connection portion 2022 and the pipe component 203. Of course, in some other embodiments, the fourth connection portion 2022 may be located between the first connection portion 301 and the pipe component 203.

[0050] In some embodiments, when assembling the heat exchange assembly, the heat exchanger 20 is first placed in the heat exchange box 10. In order to facilitate the connection between the fourth connection part 2022 and the first connection part 301, the first connection part 301 can be located between the fourth connection part 2022 and the piping component 203. That is to say, when the heat exchange box 10 is to be connected to the heat exchanger 20, the top cover 102 of the heat exchange box 10 is removed, and the first connection part 301 can be directly placed on the fourth connection part 2022 through the top of the heat exchange box 10, and then the first connection part 301 is connected to the fourth connection part 2022. There is no need to disassemble the bottom plate 103, the water receiving tray and other components of the heat exchange box 10, which is convenient for operation.

[0051] In some embodiments, the piping component 203 is connected to the outside to realize the flow of heat exchange medium. When the heat exchanger is cooling, condensed water will be generated on the piping component 203. When the first connection part 301 can be located between the fourth connection part 2022 and the piping component 203, since the fourth connection part 2022 is located below the piping component 203, along the air outlet direction, the projection of the fourth connection part 2022 on the heat exchange box body 10 and the projection of the first connection part 301 on the heat exchange box body 10 at least partially overlap, that is, the first connection part 301 is also located below the piping component 203. The condensed water on the piping component 20 will fall onto the first connection part 301 under the action of gravity, and the condensed water will be guided to the water receiving pan of the duct air conditioner through the first connection part 301 to avoid leakage of condensed water and ensure user experience.

[0052] In some embodiments, the angle between the third connection portion 2021 and the fourth connection portion 2022 may be an acute angle, a right angle, or an obtuse angle.

[0053] In some embodiments, in order to facilitate the connection between the third connection part 2021 and the fin part 201, and also to facilitate the connection between the first connection part 301 and the fourth connection part 2022, the third connection part 2021 and the fourth connection part 2022 are perpendicular. However, the vertical relationship between the third connection part 2021 and the fourth connection part 2022 is not absolutely vertical in a geometric sense. The angle relationship between the third connection part 2021 and the fourth connection part 2022 may be in the range of 90±3°.

[0054] Combination Figure 4 and Figure 5 In some embodiments, in order to prevent leakage of condensed water, the third connection part 2021 is arranged opposite to the second connection part 302, and the third connection part 2021, the first connection part 301 and the second connection part 302 are surrounded to form a drainage groove 204, that is, the drainage groove 204 is U-shaped, and the condensed water on the piping component 203 will fall on the first connection part 301 under the action of gravity, and the drainage groove 204 can guide the condensed water to the water receiving tray, and the third connection part 2021 and the second connection part 302 can block the condensed water on both sides of the drainage groove 204, so that the condensed water is collected in the drainage groove 204, and the condensed water is prevented from splashing out of the drainage groove 204 when dripping onto the first connection part 301. At the same time, the condensed water is collected together to prevent the condensed water from dispersing, and the amount of condensed water gathered in the drainage groove 304 is increased, so as to reduce the risk of wind blowing the drop-shaped condensed water out of the air conditioner and splashing the clothes or other items of people close to the air conditioner, thereby ensuring the user experience.

[0055] Combination Figure 4 and Figure 5In some embodiments, in order to guide the condensed water to the water receiving tray, the drainage groove 204 has a water outlet 205, and the width of the water outlet 205 is smaller than the width of the drainage groove 204. The condensed water gathered in the drainage groove 204 can flow to the water receiving tray through the water outlet 205, thereby preventing the condensed water on the piping component 203 from dripping outside the water receiving tray, preventing the condensed water from leaking, and ensuring the user experience.

[0056] Combination Figure 4 , Figure 5 and Figure 6 In some embodiments, in order to prevent the condensed water from splashing out of the drainage groove 204 when dripping onto the first connection part 301, and at the same time, in order to collect the condensed water together, the connection member 30 further includes: a guide part 305. The guide part 305 is connected to the first connection part 301 and the second connection part 302, and the guide part 305 is spaced apart from the third connection part 2021 to form a water outlet 205.

[0057] In some embodiments, when condensed water is generated on the piping component 203, the condensed water will fall onto the first connection part 301 under the action of gravity, and the condensed water will be blocked by the third connection part 2021 and the second connection part 302, thereby preventing the condensed water from splashing out of the drainage groove 204. When there is wind in the air duct unit, the condensed water dripping onto the first connection part 301 will flow to the guide part 305 under the action of gravity, and will be gathered at the guide part 305 to prevent the condensed water from being dispersed, increase the amount of condensed water gathered in the drainage groove 204, reduce the risk of the wind blowing the drop-shaped condensed water out of the air conditioner and splashing the clothes or other items of people near the air conditioner, and ensure the user experience. The gathered condensed water is guided to the water outlet 205 through the guide part 305 and flows to the water receiving tray, thereby preventing the condensed water on the piping component 203 from dripping out of the water receiving tray, preventing the condensed water from leaking, and ensuring the user experience.

[0058] Combination Figure 6 In some embodiments, the guide portion 305 is arranged at an angle to the second connection portion 302, wherein the angle between the guide portion 305 and the second connection portion 302 can be an acute angle, a right angle, or an obtuse angle.

[0059] In some embodiments, in order to facilitate the collected condensed water to be guided to the water outlet 205 through the guide portion 305, the guide portion 305 is perpendicular to the second connection portion 302. However, the vertical relationship between the guide portion 305 and the second connection portion 302 is not absolutely vertical in a geometric sense. The angle relationship between the guide portion 305 and the second connection portion 302 may be in the range of 90±3°.

[0060] In some embodiments, in order to ensure the structural strength of the connecting member 20 , the guide portion 305 and the second connecting portion 302 may be integrally formed, that is, the guide portion 305 may be a folded edge of the second connecting portion 302 .

[0061] In some embodiments, in order to ensure that the condensed water can be collected at the guide portion 305 , the guide portion 305 protrudes from the surface of the first connecting portion 301 .

[0062] Figure 7 for Figure 6 Top view of the connector. Figure 4 , Figure 6 and Figure 7 In some embodiments, in order to facilitate the connection between the first connection part 301 and the fourth connection part 2022, one of the first connection part 301 and the fourth connection part 2022 is provided with a buckle 303, and the other is provided with a slot 2023, and the buckle 303 can be locked in the slot 2023.

[0063] In some embodiments, when connecting the first connection part 301 and the fourth connection part 2022, the buckle 303 is snapped into the slot 2023 to achieve pre-installation of the first connection part 301. By snapping the buckle 303 into the slot 2023, when the first connection part 301 is fastened to the fourth connection part 2022, there is no need to hold the first connection part 301, which is convenient for the installer to install the first connection part 301 and improves the installation efficiency.

[0064] In some embodiments, the first connection part 301 can be positioned on the fourth connection part 2022 by engaging the buckle 303 in the slot 2023 , thereby ensuring the accuracy of the installation position of the first connection part 301 and further improving the installation efficiency.

[0065] In some embodiments, the first connection portion 301 may be provided with a buckle 303, and the fourth connection portion 2022 may be provided with a slot 2023. In other embodiments, the fourth connection portion 2022 may be provided with a buckle 303, and the first connection portion 301 may be provided with a slot 2023.

[0066] After the heat exchanger 20 is installed on the support plate 40, the heat exchanger 20 is fixed to the support plate 40 from the inside of the heat exchange box 10 by large screws. The internal space of the heat exchange box 10 is narrow, which makes operation inconvenient and easy to hit the copper tube of the heat exchanger 20, causing damage to the copper tube. Figure 2 and Figure 3 In some embodiments, for ease of operation, the heat exchange assembly further includes: a locking member 50. The locking member 50 includes an operating portion 501 and a locking portion 502 connected to the operating portion 501. The locking portion 502 is disposed through the heat exchange box 10 and connected to the second connecting portion 302. The operating portion 501 is located outside the heat exchange box 10.

[0067] In some embodiments, when the heat exchanger 20 is to be fixed in the heat exchange box 10, the operating part 501 can be operated outside the heat exchange box 10, and the operating part 501 can drive the locking part 502 to penetrate the heat exchange box 10 and connect with the second connecting part 302 to fix the heat exchanger 20. There is no need to operate inside the heat exchange box 10. There can be enough space outside the heat exchange box 10 to facilitate the connection between the second connecting part 302 and the heat exchange box 10, thereby reducing the difficulty of installation, reducing the workload, facilitating operation, and improving work efficiency. Moreover, when operating outside the heat exchange box 10, the copper tubes of the heat exchanger 20 will not be touched, thereby avoiding damage to the copper tubes of the heat exchanger 20 and ensuring the safety of the copper tubes of the heat exchanger 20.

[0068] Combination Figure 3 , Figure 4 and Figure 6 In some embodiments, in order to reduce the possibility of air leakage, the heat exchange box 10 includes a main body 104 and a top cover 102 connected to the main body 104, and the connector 30 further includes: a shielding portion 304. The shielding portion 304 is connected to the first connecting portion 301 and is arranged opposite to the second connecting portion 302. The shielding portion 304 conflicts with the heat exchanger 20, the main body 104 and the top cover 102.

[0069] When the heat exchanger 20 is placed in the heat exchange box 10, there will be a gap between the heat exchange box 20 and the side plate 101 of the heat exchange box 20. The gap is to accommodate the piping components 203 of the heat exchanger 20. However, after the wind passes through the heat exchanger 20, wind will enter the gap in a direction that is angled with the wind outlet direction, resulting in air leakage. Figure 3 , Figure 4 and Figure 6 In some embodiments, after the wind passes through the heat exchanger 20, the shielding portion 304 can block the wind in a direction that is angled with the wind outlet direction, preventing the wind from entering the gap between the heat exchange box 20 and the side plate 101 of the heat exchange box 20, thereby reducing the possibility of air leakage, ensuring the wind outlet volume, and improving the user experience. The extending direction of the shielding portion 304 can be consistent with the wind outlet direction.

[0070] In some embodiments, in order to prevent the shielding portion 304 from affecting the air volume, along the air outlet direction, the projection of the shielding portion 304 and the projection of the edge of the heat exchanger 20 at least partially overlap on the main body 104, that is, along the air outlet direction, the shielding portion 304 will not block the wind and will not interfere with the flow of wind, thereby ensuring smooth discharge of wind and ensuring the air volume. In particular, along the air outlet direction, the projection of the shielding portion 304 and the projection of the third connecting portion 2021 of the side plate 20 at least partially overlap on the main body 104.

[0071] In some embodiments, the shielding portion 304 may be flush with the edge of the heat exchanger 20 , that is, the projection of the shielding portion 304 overlaps with the projection of the edge of the heat exchanger 20 on the main body 104 .

[0072] Based on the same utility model concept, the present application also proposes a duct air conditioner, which adopts the heat exchange component. The specific structure of the heat exchange component refers to the above-mentioned embodiment. Since the heat exchange component adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0073] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "leveling", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0074] In addition, in this application, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated.
