[0038] In the description of the present invention, "multiple" means two or more, and "several" means one or more.

[0039] Reference below Figure 1-Figure 10 The duct machine 1 according to the embodiment of the utility model is described.

[0040] like Figure 1-Figure 10 As shown, the duct machine 1 according to the embodiment of the utility model may include a housing 100, the housing 100 may form an air inlet 110 and an air outlet 120, and the housing 100 may form a receiving space to facilitate fixing and protecting the components of the duct machine 1. There may be multiple air inlets 110, for example, one of which may be an indoor air inlet 110, and another one may be an outdoor fresh air inlet.

[0041] The duct unit 1 may include a heat exchanger 200. When the duct unit 1 is working, indoor air or outdoor air can flow into the casing 100 from the air inlet 110 of the casing 100, and then be discharged into the room through the air outlet 120 after heat exchange with the heat exchanger 200 to form a heat exchange airflow. The heat exchanger 200 can then be used to heat the airflow or cool the airflow to achieve heating or cooling of the indoor air.

[0042] It should be noted that the length direction in the drawings refers to the length direction of the heat exchanger 200 , and the width direction in the drawings refers to the width direction of the heat exchanger 200 . The length direction of the heat exchanger 100 is consistent with the length direction of the casing 100 , and the width direction of the heat exchanger 100 is consistent with the width direction of the casing 100 .

[0043] The air duct machine 1 may include an air duct member 300, and the heat exchanger 200 may be arranged in the air duct member 300. The air duct member 300 can guide the air flowing into the casing 100 so that the airflow can flow more evenly and orderly, and the air flowing into the casing 100 can flow through the heat exchanger 200 and exchange heat with the heat exchanger 200 to improve the heat exchange efficiency.

[0044] The air duct unit 1 may include a fan, which can be operated to drive air flow to speed up the flow rate of the air flow, thereby improving the heat exchange efficiency between the air and the heat exchanger 200 to improve the cooling or heating efficiency of the air duct unit 1.

[0045] The duct machine 1 may include a fixing plate 310, which is fixed to the casing 100, and the duct member 300 is fixed to the fixing plate 310, so that the duct member 300 can be fixed by the fixing plate 310 to fix the position of the duct member 300 and prevent the duct member 300 from shaking relative to the casing 100.

[0046] Specifically, the casing 100 is formed with an air inlet 110 and an air outlet 120 on two sides opposite to each other, the heat exchanger 200 is arranged in the casing 100 and adjacent to the air outlet 120, the duct member 300 is arranged in the casing 100 and adjacent to the air inlet 110, the fan is arranged in the duct member 300, the fan drives the air to enter the casing 100 from the air inlet 110, and the air flows to the heat exchanger 200 through the duct member 300, and enters the room through the air outlet 120 after heat exchange with the heat exchanger 200, the fixing plate 310 is arranged in the casing 100 and is located between the heat exchanger 200 and the duct member 300, and the duct member 300 is installed on the fixing plate 310.

[0047] The air duct machine 1 may further include a support bracket 400, which may be supported on the middle part of the heat exchanger 200, and the support bracket 400 may be used to provide auxiliary support to the heat exchanger 200. The middle part of the heat exchanger 200 may be supported, thereby improving the support stability of the heat exchanger 200 and preventing the air duct machine 1 from being vibrated or impacted so that the heat exchanger 200 moves toward the fixed plate 310, that is, the heat exchanger 200 is not prone to shaking, thereby helping to reduce the probability of deformation of the heat exchanger 200 during transportation or handling, and improving the reliability of the air duct machine 1.

[0048] Specifically, the support bracket 400 is connected to the fixing plate 310 and is located on a side of the heat exchanger 200 close to the fixing plate 310 in the thickness direction, that is, the support bracket 400 can support a side of the heat exchanger 200 close to the fixing plate 310 in the thickness direction.

[0049] In this way, according to the air duct machine 1 of the embodiment of the utility model, by setting a supporting bracket 400 in the middle of the heat exchanger 200, effective support for the heat exchanger 200 is achieved, thereby greatly improving the supporting stability of the heat exchanger 200, reducing the probability of deformation of the heat exchanger 200 during transportation or handling, and improving the reliability of the air duct machine 1.

[0050] In some specific embodiments of the present invention, Figure 8-Figure 10 As shown, the support bracket 400 may include a support portion 410, and the support portion 410 is parallel to the thickness direction of the heat exchanger 200 and close to the side of the fixing plate 310. This arrangement can increase the contact area between the support portion 410 and the heat exchanger 200, and the support bracket 400 supports the heat exchanger 200 more stably, and the buffering and vibration reduction effect is better.

[0051] like Figure 8-Figure 10 As shown, the support bracket 400 may include a transition portion 420, one side of which is connected to the support portion 410 and is bent relative to the support portion 410 in a direction away from the heat exchanger 200. In other words, the transition portion 420 is bent upward relative to the support portion 410, thereby preventing the support bracket 400 from extending too far downward, thereby preventing positional interference between the transition portion 420 and the water tray 600 or other components of the duct machine 1.

[0052] like Figure 8-Figure 10 As shown, the support bracket 400 may include a connecting portion 430, the connecting portion 430 is connected to the other side of the transition portion 420 and is bent upward relative to the transition portion 420, the connecting portion 430 is attached to the fixing plate 310 and connected to the fixing plate 310, and in this way, the connecting portion 430 may extend parallel to the fixing plate 310, so that the connecting portion 430 may be attached to the fixing plate 310, and the connecting portion 430 and the fixing plate 310 are connected. The connecting portion 430 and the fixing plate 310 may be screwed and fixed by a plurality of bolts.

[0053] Specifically, Figure 8-Figure 10 As shown, the support bracket 400 may include a support portion 410, a transition portion 420 and a connecting portion 430, the elastic buffer member 500 is supported between the support portion 410 and the heat exchanger 200, one side of the transition portion 420 is connected to the support portion 410 and is bent relative to the support portion 410 in a direction away from the heat exchanger 200, the connecting portion 430 is connected to the other side of the transition portion 420 and is bent upward relative to the transition portion 420, and the connecting portion 430 is attached to the fixing plate 310 and connected to the fixing plate 310.

[0054] By bending the support bracket 400 to form the support portion 410, the transition portion 420 and the connecting portion 430, it is convenient for the support bracket 400 to be connected to the heat exchanger 200 and the fixed plate 310 at the same time, that is, while the support portion 410 uses a large surface to support the heat exchanger 200, the connecting portion 430 can also be fitted and connected to the fixed plate 310, and the structural setting is more reasonable.

[0055] Further, if Figure 3 and Fig.10 As shown, the support bracket 400 may include a plurality of first reinforcing ribs 450, which are all arranged on a side of the support portion 410 away from the heat exchanger 200 and spaced apart along the length direction of the heat exchanger 200, and the two ends of each first reinforcing rib 450 are respectively connected to the support portion 410 and the transition portion 420.

[0056] For example, in Fig. 9 and Fig.10 In the example, there are three first reinforcing ribs 450, and the three first reinforcing ribs 450 are evenly spaced apart along the length direction of the support bracket 400. The connection strength between the support portion 410 and the transition portion 420 can be improved by using multiple first reinforcing ribs 450, thereby preventing the support bracket 400 from being deformed.

[0057] like Figure 3 and Fig.10 As shown, the support bracket 400 may include a plurality of second reinforcing ribs 460, which are all arranged on a side of the connecting portion 430 away from the fixing plate 310 and spaced apart along the length direction of the heat exchanger 200, and the two ends of each second reinforcing rib 460 are respectively connected to the connecting portion 430 and the transition portion 420.

[0058] For example, in Fig. 9 and Fig.10 In the example, there are three second reinforcing ribs 460, and the three second reinforcing ribs 460 are evenly spaced apart along the length direction of the support bracket 400. The connection strength between the connecting portion 430 and the transition portion 420 can be improved by using multiple second reinforcing ribs 460, thereby preventing the support bracket 400 from being deformed.

[0059] The support bracket 400 may include a plurality of first reinforcing ribs 450 and a plurality of second reinforcing ribs 460. The plurality of first reinforcing ribs 450 and the plurality of second reinforcing ribs 460 may be located on the same side of the thickness direction of the support bracket 400. This arrangement can reduce the thickness of the support bracket 400 and avoid interference between the support bracket 400 and other components. At the same time, it can improve the connection strength between the support portion 410, the transition portion 420 and the connecting portion 430, thereby improving the structural strength of the support bracket 400.

[0060] Specifically, the plurality of first reinforcing ribs 450 are all located at the connection between the support portion 410 and the transition portion 420, and the plurality of first reinforcing ribs 450 are respectively connected to the support portion 410 and the transition portion 420, and the plurality of first reinforcing ribs 450 can be arranged at the angle side between the support portion 410 and the transition portion 420, and the connection strength between the support portion 410 and the transition portion 420 can be improved by the plurality of first reinforcing ribs 450. Part of the connection between the support portion 410 and the transition portion 420 is recessed in a direction away from the heat exchanger 200 to form the first reinforcing rib 450, so that while improving the connection strength between the support portion 410 and the transition portion 420, the material usage of the support bracket 400 can be reduced, thereby reducing the cost.

[0061] And / or, the plurality of second reinforcing ribs 460 are all located at the connection between the transition part 420 and the connection part 430, the plurality of second reinforcing ribs 460 are respectively connected to the transition part 420 and the connection part 430, and the plurality of second reinforcing ribs 460 can be arranged at the angle side between the transition part 420 and the connection part 430, and then the connection strength between the transition part 420 and the connection part 430 can be improved by the plurality of second reinforcing ribs 460, so that the structural strength of the support bracket 400 can be higher. Among them, the connection between part of the connection part 430 and the transition part 420 is recessed in the direction away from the fixing plate 310 to form the second reinforcing ribs 460, so that while improving the connection strength between the connection part 430 and the transition part 420, the material usage of the support bracket 400 can be further reduced, and the cost can be further reduced.

[0062] In some specific embodiments of the present invention, Figure 8-Figure 10 As shown, the support portion 410 is bent at both ends in the length direction of the heat exchanger 200 to form a first flange 411, wherein the first flange 411 can be bent upward, that is, bent in a direction away from the heat exchanger 200, thereby avoiding position interference between the first flange 411 and the heat exchanger 200 and improving the structural strength of the support portion 410.

[0063] In some specific embodiments of the present invention, Figure 8-Figure 10 As shown, the transition portion 420 is bent at both ends in the length direction of the heat exchanger 200 to form a second flange 421, wherein the second flange 421 can be bent upward, that is, the second flange 421 can be bent in a direction away from the water receiving tray 600, thereby avoiding position interference between the second flange 421 and the water receiving tray 600 and improving the structural strength of the transition portion 420.

[0064] In some specific embodiments of the present invention, Figure 8-Figure 10As shown, the connecting portion 430 is bent at both ends in the length direction of the heat exchanger 200 to form a third flange 431, wherein the third flange 431 can be bent in a direction away from the fixing plate 310, thereby avoiding position interference between the third flange 431 and the fixing plate 310 and improving the structural strength of the connecting portion 430.

[0065] In addition, by providing the support portion 410 with a first flange 411, the transition portion 420 with a second flange 421, and the connection portion 430 with a third flange 431, the overall stiffness of the support bracket 400 can be greatly improved, and the overall structural strength of the support bracket 400 can be higher and the supporting stability can be better.

[0066] In some specific embodiments of the present invention, Figure 8-Figure 10 As shown, at least a portion of the first flange 411 and at least a portion of the second flange 421 are stacked and connected to each other.

[0067] At least a portion of the third flange 431 and at least another portion of the second flange 421 are stacked and connected to each other.

[0068] Among them, the first flange 411 and the third flange 431 can both be arranged on the outside of the second flange 421; or, the first flange 411 and the third flange 431 can both be arranged on the inside of the second flange 421; or, the first flange 411 can be arranged on the inside of the second flange 421 and the third flange 431 can be arranged on the outside of the second flange 421; or, the first flange 411 can be arranged on the outside of the second flange 421 and the third flange 431 can be arranged on the inside of the second flange 421.

[0069] In addition, the first flange 411 and the second flange 421 can be connected by welding, and the second flange 421 and the third flange 431 can be connected by welding, which further improves the overall structural strength of the support bracket 400, the rigidity of the support bracket 400 can be higher, and the support for the heat exchanger 200 can be more stable.

[0070] In addition, by stacking the first flange 411 and the third flange 431 on different parts of the second flange 421, there will be no positional interference between the first flange 411 and the third flange 431, so that the first flange 411 and the third flange 431 are respectively connected to the second flange 421, and the first flange 411, the second flange 421 and the third flange 431 will not be stacked at the same time, thereby avoiding the thickness of the support bracket 400 at the flange position being too thick, and the structural setting is more reasonable.

[0071] In some embodiments of the present invention, the support bracket 400 is configured with a drainage hole 440, and the drainage hole 440 penetrates the bottom wall and / or the side wall of the support bracket 400. For example, the drainage hole 440 may penetrate the bottom wall of the support bracket 400; or, the drainage hole 440 may penetrate the side wall of the support bracket 400; or, the drainage hole 440 may penetrate both the bottom wall and the side wall of the support bracket 400.

[0072] In this way, the drainage hole 440 can be located at the lowest point of the support bracket 400. It can be understood that when the condensed water on the heat exchanger 200 splashes onto the support bracket 400, or the support bracket 400 itself is insufficiently insulated and condensed water condenses, the condensed water can be discharged through the drainage hole 440 to prevent excessive accumulation of condensed water on the drainage bracket, so that the condensed water can flow downward into the water receiving tray 600, and then through a water pump or natural drainage, finally discharged to the outside of the air duct machine 1, thereby more effectively reducing the pollution of condensed water.

[0073] Specifically, Figure 5-Figure 10 As shown, there are multiple drainage holes 440, and the multiple drainage holes 440 are arranged on opposite sides of the support bracket 400, and the drainage holes 440 are located at the lowest point of the support bracket 400 in the up and down direction.

[0074] In this way, the condensed water on the support bracket 400 can be discharged simultaneously by using the multiple drainage holes 440 on the opposite sides of the support bracket 400, thereby improving the drainage efficiency of the condensed water on the support bracket 400 and more effectively avoiding the accumulation of condensed water on the support bracket 400.

[0075] Moreover, the drainage hole 440 is located at the lowest point of the support bracket 400 in the up-down direction, which can ensure that the multiple drainage holes 440 can drain the drainage holes 440 on the support bracket 400 more thoroughly and avoid condensed water residue on the support bracket 400.

[0076] In some specific embodiments of the present invention, Figure 5 As shown, the first flange 411 may be provided with a first notch 412 .

[0077] The second flange 421 may be provided with a second notch 422 .

[0078] The first notch 412, the second notch 422, the support portion 410 and the transition portion 420 jointly define a drainage hole 440. With this arrangement, the first notch 412 and the second notch 422 can be used to increase the cross-sectional area of ​​the drainage hole 440, and the drainage hole 440 can be larger, with better drainage effect and higher drainage efficiency, so that the condensed water on the support bracket 400 can be more thoroughly discharged by using the drainage hole 440. In addition, the drainage hole 440 will not damage the structure of the connection between the support portion 410 and the transition portion 420, and the connection strength between the support portion 410 and the transition portion 420 can be higher.

[0079] In some specific embodiments of the present invention, Figure 2 As shown, the air duct unit 1 may include a water receiving tray 600 .

[0080] The water receiving pan 600 is arranged in the housing 100 and below the heat exchanger 200, and is projected into the horizontal plane along the up-down direction, and the projection of the drainage hole 440 is located within the projection of the water receiving pan 600. In this arrangement, even if condensed water is generated on the support bracket 400, the condensed water can flow downward into the water receiving pan 600 through the drainage hole 440, which more effectively prevents the condensed water on the support bracket 400 from flowing to the outside of the water receiving pan 600, and the water receiving pan 600 has a better effect of collecting condensed water.

[0081] In some specific embodiments of the present invention, Figure 1 , Figure 3 and Figure 5 As shown, the duct unit 1 may further include an elastic buffer 500. The elastic buffer 500 in this embodiment may be sponge or rubber.

[0082] The elastic buffer 500 is connected to the side of the support bracket 400 facing the heat exchanger 200, and is disposed between the support bracket 400 and the heat exchanger 200. The elastic buffer 500 may also be disposed parallel to the thickness direction of the heat exchanger 200 and close to the fixing plate 310.

[0083] By setting the elastic buffer 500, the elastic buffer 500 can absorb the vibration of the heat exchanger 200 and buffer the heat exchanger 200, avoiding the rigid connection between the support bracket 400 and the heat exchanger 200, thereby reducing the impact force of the support bracket 400 on the heat exchanger 200, avoiding the support bracket 400 squeezing the heat exchanger 200 to cause the fins to fall over. In addition, the elastic buffer 500 can also separate the support bracket 400 and the heat exchanger 200, avoiding the support bracket 400 directly contacting the heat exchanger 200. When the duct machine 1 is cooling, the coldness of the heat exchanger 200 is not easily transferred to the support bracket 400, so as to greatly reduce the amount of condensed water generated on the support bracket 400, and even avoid the generation of condensed water on the support bracket 400, effectively avoiding pollution caused by excessive condensation of condensed water.

[0084] In addition, it should be noted that during assembly, the reserved gap between the support bracket 400 and the heat exchanger 200 can be slightly smaller than the thickness of the elastic buffer 500, so that the support bracket 400 can press the elastic buffer 500 against the heat exchanger 200, and more effectively utilize the elastic buffer 500 to cushion and reduce vibration of the heat exchanger 200.

[0085] In some specific embodiments, the reserved gap between the support bracket 400 and the heat exchanger 200 is H, and 3 mm≤H.

[0086] That is to say, the reserved gap H between the support bracket 400 and the heat exchanger 200 cannot be too small. If the reserved gap H between the support bracket 400 and the heat exchanger 200 is too small, it may cause the assembly error of the support bracket 400 and the heat exchanger 200 to be greater than the reserved gap H, which is not only not conducive to the assembly of the support bracket 400, the elastic buffer 500 and the heat exchanger 200, but also may cause the support bracket 400 to exert too much pressure on the elastic buffer 500 and the heat exchanger 200, and the fins of the heat exchanger 200 are prone to lodging. Therefore, the reserved gap H between the support bracket 400 and the heat exchanger 200 cannot be less than 3mm.

[0087] Preferably, the reserved gap H between the support bracket 400 and the heat exchanger 200 is not less than 4.5 mm, so as to avoid the reserved gap H between the support bracket 400 and the heat exchanger 200 being too small, and the reserved gap H can be used to absorb the assembly error of the support bracket 400 and the heat exchanger 200, so that the assembly is more convenient. After the assembly is completed, the extrusion force of the support bracket 400 on the elastic buffer 500 and the heat exchanger 200 can be smaller, and the heat exchanger 200 will not be squeezed and deformed.

[0088] Further preferably, the reserved gap H between the support bracket 400 and the heat exchanger 200 is not less than 7.5 mm, so that the reserved gap H between the support bracket 400 and the heat exchanger 200 can be larger, and the reserved gap H can be used to fully absorb the assembly error of the support bracket 400 and the heat exchanger 200, so that the assembly is more convenient, and the squeezing force of the support bracket 400 on the elastic buffer 500 and the heat exchanger 200 can be smaller, further avoiding the problem of the fins of the heat exchanger 200 being squeezed and deformed.

[0089] In some specific embodiments, the reserved gap between the support bracket 400 and the heat exchanger 200 is H, and H≤15 mm.

[0090] That is to say, the reserved gap H between the support bracket 400 and the heat exchanger 200 cannot be too large. If the reserved gap H between the support bracket 400 and the heat exchanger 200 is too large, the reserved gap H may be larger than the thickness of the elastic buffer 500, and the support bracket 400 cannot press the elastic buffer 500 against the heat exchanger 200, and the elastic buffer 500 has a poor buffering and vibration reduction effect on the heat exchanger 200. Therefore, the reserved gap H between the support bracket 400 and the heat exchanger 200 cannot be greater than 15 mm.

[0091] Preferably, the reserved gap H between the support bracket 400 and the heat exchanger 200 is not greater than 12 mm. This can prevent the reserved gap H between the support bracket 400 and the heat exchanger 200 from being too large, so that the reserved gap H can be smaller than the thickness of the elastic buffer 500. The support bracket 400 can press the elastic buffer 500 against the heat exchanger 200, and the elastic buffer 500 has a better buffering and vibration reduction effect on the heat exchanger 200.

[0092] Further preferably, the reserved gap H between the support bracket 400 and the heat exchanger 200 is not greater than 10 mm, so that the reserved gap H can be set to be smaller within an appropriate range to ensure that the reserved gap H can be smaller than the thickness of the elastic buffer 500. The support bracket 400 can press the elastic buffer 500 against the heat exchanger 200 more stably, further improving the buffering and vibration reduction effect of the elastic buffer 500 on the heat exchanger 200.

[0093] In some specific embodiments, the reserved gap between the support bracket 400 and the heat exchanger 200 is H, 3mm≤H≤15mm. This arrangement ensures that the support bracket 400 and the elastic buffer 500 will not excessively squeeze the heat exchanger 200, and can also ensure that the support bracket 400 can press the elastic buffer 500 against the heat exchanger 200, and the elastic buffer 500 can buffer and reduce vibration of the heat exchanger 200.

[0094] In addition, it should be noted that the common thickness values ​​of the elastic buffer 500 are usually 3mm, 5mm, 8mm, 10mm, 12mm and 15mm. By setting the reserved gap H between the support bracket 400 and the heat exchanger 200 to any value between 3mm and 15mm, it is necessary to ensure that the thickness of the elastic buffer 500 is not less than the reserved gap H. In this way, the elastic buffer 500 can be interference fit between the support bracket 400 and the heat exchanger 200 to ensure that the support bracket 400 can press the elastic buffer 500 against the heat exchanger 200, so that the elastic buffer 500 can buffer and reduce vibration of the heat exchanger 200.

[0095] In some specific embodiments of the present invention, Figure 5 As shown, along the width direction of the heat exchanger 200 , the upper side edge of the support portion 410 facing the heat exchanger 200 extends upward beyond the upper side surface of the elastic buffer 500 .

[0096] That is to say, along the width direction of the heat exchanger 200, the upper side surface of the elastic buffer 500 is lower than the upper side surface of the support portion 410. In this way, when condensed water is generated on the heat exchanger 200 and the condensed water flows along the heat exchanger 200 to the elastic buffer 500, the condensed water will not overflow over the elastic buffer 500 and overflow to the side of the support portion 410 facing away from the heat exchanger 200, thereby preventing the condensed water from overflowing onto the support bracket 400. The condensed water can be diverted to both sides of the length direction of the elastic buffer 500 and flow downward into the water receiving tray 600 to collect the condensed water, thereby preventing the condensed water from causing pollution.

[0097] In some specific embodiments of the present invention, Figure 6 and Figure 7 As shown, along the width direction of the heat exchanger 200, the lower side of the elastic buffer 500 is flush with the lower side of the support portion 410 on the side facing the heat exchanger 200. In this way, in the width direction of the heat exchanger 200, the lower side of the elastic buffer 500 and the lower side of the support portion 410 on the side facing the heat exchanger 200 are more regularly arranged, and it is also beneficial to increase the contact area between the elastic buffer 500 and the support bracket 400, and the connection between the elastic buffer 500 and the support bracket 400 is more stable. At the same time, the contact area between the elastic buffer 500 and the heat exchanger 200 can also be increased, thereby improving the buffering and vibration reduction effect of the elastic buffer 500 on the heat exchanger 200.

[0098] In other specific embodiments of the present invention, Figure 6 and Figure 7As shown, along the length direction of the heat exchanger 200, the two opposite sides of the elastic buffer 500 are flush with the two opposite sides of the support portion 410. In this way, in the width direction of the heat exchanger 200 and along the length direction of the heat exchanger 200, the structural arrangement of the two opposite sides of the elastic buffer 500 and the two opposite sides of the support portion 410 is more regular, and it is conducive to increasing the contact area between the elastic buffer 500 and the support portion 410, and the connection between the elastic buffer 500 and the support bracket 400 is more stable. At the same time, the contact area between the elastic buffer 500 and the heat exchanger 200 can also be increased, thereby improving the buffering and vibration reduction effect of the elastic buffer 500 on the heat exchanger 200.

[0099] In some specific embodiments of the utility model, the air duct machine 1 may include a first thermal insulation component (not shown in the figure), which covers one side of the support bracket 400 in the thickness direction. In this way, the first thermal insulation component can be used to block the heat exchanger 200 from transferring cold to the support bracket 400 or to the fixed plate 310, thereby reducing the amount of condensed water generated on the support bracket 400 or the fixed plate 310, which is beneficial to reducing the pollution of condensed water.

[0100] In addition, the first thermal insulation component avoids the elastic buffer component 500 and the drainage hole 440, and the first thermal insulation component will not interfere with the elastic buffer component 500, which is convenient for the first thermal insulation component and the elastic buffer component 500 to be respectively connected to the support bracket 400, and the first thermal insulation component will not block the drainage hole 440 from draining water, which is convenient for the support bracket 400 to discharge condensed water.

[0101] The duct machine 1 may further include a second thermal insulation component (not shown in the figure), which covers the other side of the support bracket 400 in the thickness direction, and the second thermal insulation component avoids the drainage hole 440. In this way, the second thermal insulation component can also be used to block the heat exchanger 200 from transferring cold to the support bracket 400 or to the fixed plate 310, thereby reducing the amount of condensed water generated on the support bracket 400 or the fixed plate 310, which is beneficial to reducing the pollution of condensed water.

[0102] Furthermore, the second heat-insulating component avoids the drainage hole 440, and the second heat-insulating component will not block the drainage hole 440, so that the support bracket 400 can drain the condensed water more smoothly.

[0103] Specifically, the air duct machine 1 may include a first thermal insulation component and a second thermal insulation component. The first thermal insulation component covers one side of the support bracket 400 in the thickness direction, and the first thermal insulation component avoids the elastic buffer component 500 and the drainage hole 440. The second thermal insulation component covers the other side of the support bracket 400 in the thickness direction, and the second thermal insulation component avoids the drainage hole 440.

[0104] In this way, the first thermal insulation component and the second thermal insulation component can cover the opposite sides of the support bracket 400 in the thickness direction, thereby increasing the covering area of ​​the first thermal insulation component and the second thermal insulation component on the support bracket 400. The first thermal insulation component and the second thermal insulation component have a better insulation effect on the support bracket 400, further improving the effect of the isolation heat exchanger 200 transferring cold to the support bracket 400 or to the fixed plate 310. It is less likely to generate condensation water on the support bracket 400 and the fixed plate 310, and the first thermal insulation component and the second thermal insulation component can avoid the drainage hole 440. Even if condensation water is generated on the support bracket 400, it can be drained through the drainage hole 440.

[0105] In some specific embodiments of the utility model, the air duct machine 1 may include a plurality of connectors 210, which are respectively arranged at both ends of the length direction of the heat exchanger 200, and each connector 210 is respectively connected to one side of the thickness direction of the heat exchanger 200 and the inner wall of the housing 100. For example, one end of the heat exchanger 200 in the length direction may be connected to the inner side wall of the housing 100 in the length direction through a triangular sheet metal, and the other end of the heat exchanger in the length direction may be connected to the inner side wall of the housing 100 in the width direction through a connecting plate. Thus, the connector 210 may be supported between the heat exchanger 200 and the housing 100 to fix the heat exchanger 200 in the housing 100, and the connector 210 may be used to support the heat exchanger 200 to prevent the heat exchanger 200 from shaking.

[0106] For example, a plurality of connectors 210 may be connected between the lower side of the heat exchanger 200 and the housing 100 , and the support bracket 400 may be connected to the fixing plate 310 and supported on the upper side of the heat exchanger 200 .

[0107] That is to say, the side of the heat exchanger 200 in the thickness direction away from the fixed plate 310 can be supported and fixed by the connecting piece 210, and the side of the heat exchanger 200 in the thickness direction close to the fixed plate 310 can be supported and fixed by the supporting bracket 400. The supporting bracket 400 and multiple connecting pieces 210 can be respectively arranged at both ends and the middle of the heat exchanger 200 to achieve at least three-point support and fixation of the heat exchanger 200, thereby greatly improving the supporting stability of the heat exchanger 200 and avoiding shaking of the heat exchanger 200 during transportation or handling.

[0108] The following describes an air duct machine 1 according to another embodiment of the present invention with reference to the accompanying drawings.

[0109] like Figure 1-Figure 10As shown, the duct machine 1 according to the embodiment of the utility model may include a housing 100, the housing 100 may form an air inlet 110 and an air outlet 120, and the housing 100 may form a receiving space to facilitate fixing and protecting the components of the duct machine 1. There may be multiple air inlets 110, for example, one of which may be an indoor air inlet 110, and another one may be an outdoor fresh air inlet.

[0110] The duct unit 1 may include a heat exchanger 200. When the duct unit 1 is working, indoor air or outdoor air can flow into the casing 100 from the air inlet 110 of the casing 100, and then be discharged into the room through the air outlet 120 after heat exchange with the heat exchanger 200 to form a heat exchange airflow. The heat exchanger 200 can then be used to heat the airflow or cool the airflow to achieve heating or cooling of the indoor air.

[0111] The air duct machine 1 may include an air duct member 300, and the heat exchanger 200 may be arranged in the air duct member 300. The air duct member 300 can guide the air flowing into the casing 100 so that the airflow can flow more evenly and orderly, and the air flowing into the casing 100 can flow through the heat exchanger 200 and exchange heat with the heat exchanger 200 to improve the heat exchange efficiency.

[0112] The air duct unit 1 may include a fan, which can be operated to drive air flow to speed up the flow rate of the air flow, thereby improving the heat exchange efficiency between the air and the heat exchanger 200 to improve the cooling or heating efficiency of the air duct unit 1.

[0113] The duct machine 1 may include a fixing plate 310, which is fixed to the casing 100, and the duct member 300 is fixed to the fixing plate 310, so that the duct member 300 can be fixed by the fixing plate 310 to fix the position of the duct member 300 and prevent the duct member 300 from shaking relative to the casing 100.

[0114] Specifically, the casing 100 is formed with an air inlet 110 and an air outlet 120 on two sides opposite to each other, the heat exchanger 200 is arranged in the casing 100 and adjacent to the air outlet 120, the duct member 300 is arranged in the casing 100 and adjacent to the air inlet 110, the fan is arranged in the duct member 300, the fan drives the air to enter the casing 100 from the air inlet 110, and the air flows to the heat exchanger 200 through the duct member 300, and enters the room through the air outlet 120 after heat exchange with the heat exchanger 200, the fixing plate 310 is arranged in the casing 100 and is located between the heat exchanger 200 and the duct member 300, and the duct member 300 is installed on the fixing plate 310.

[0115] The duct unit 1 may further include a support bracket 400, the two ends of the support bracket 400 are respectively abutted against the fixing plate 310 and a side of the heat exchanger 200 in the thickness direction close to the fixing plate 310. The support bracket 400 may be located in the middle of the heat exchanger 200 in the length direction of the heat exchanger 200, and the support bracket 400 may be used to provide auxiliary support to the heat exchanger 200. Both ends and the middle of the heat exchanger 200 may be supported, thereby further improving the support stability of the heat exchanger 200, making the heat exchanger 200 less prone to shaking, thereby reducing the probability of deformation of the heat exchanger 200 during transportation or handling, and improving the reliability of the duct unit 1.

[0116] Specifically, one end of the support bracket 400 abuts against the fixed plate 310, and the other end of the support bracket 400 abuts against a side of the heat exchanger 200 close to the fixed plate 310 in the thickness direction, that is, the support bracket 400 can support the side of the heat exchanger 200 close to the fixed plate 310 in the thickness direction.

[0117] According to the air duct machine 1 of the embodiment of the utility model, a supporting bracket 400 is arranged in the middle of the heat exchanger 200 to achieve effective support for the heat exchanger 200, thereby greatly improving the supporting stability of the heat exchanger 200, reducing the probability of deformation of the heat exchanger 200 during transportation or handling, and improving the reliability of the air duct machine 1.

[0118] Other structures and operations of the duct machine 1 according to the embodiment of the utility model are known to ordinary technicians in this field and will not be described in detail here.

[0119] The duct air conditioner 1 in the present invention performs a refrigeration cycle of the duct air conditioner 1 by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0120] The compressor compresses the refrigerant gas in a high temperature and high pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0121] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air duct unit 1 can adjust the temperature and humidity of the indoor space.
