[0030] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application and should not be construed as a limitation to the present application.

[0031] The following refers to Figures 1 - 7 Describe the outdoor unit 100 of the air conditioner according to the embodiment of the present application.

[0032] An air conditioner usually includes an outdoor unit 100 and an indoor unit of the air conditioner. The outdoor unit 100 is arranged outdoors and can cool and dissipate heat the high-pressure and high-temperature gas discharged from the indoor unit of the air conditioner outdoors through the heat exchanger 2 and the fan, condense the refrigerant and then send it to the evaporator of the indoor unit of the air conditioner through the throttling device. The refrigerant evaporates and absorbs heat at the evaporator to realize the refrigeration function of the indoor unit of the air conditioner.

[0033] In the related art, the air inlet area of the outdoor unit 100 of the air conditioner is insufficient, resulting in a small air inlet volume and high noise at the outdoor unit 100 of the air conditioner, and at the same time resulting in an unsatisfactory heat exchange effect of the heat exchanger 2, and further resulting in low energy efficiency of the air conditioner.

[0034] The outdoor unit 100 of the air conditioner according to the embodiment of the present application includes a shell 1 and a heat exchanger 2. An air inlet structure is provided on the shell 1, and the air inlet structure includes an air inlet 101 provided on the top plate 11 of the shell 1. The heat exchanger 2 is arranged in the shell 1, and at least part of the heat exchanger 2 is arranged opposite to the air inlet 101.

[0035] Among them, the air outside the outdoor unit 100 of the air conditioner can enter the shell 1 through the air inlet structure, and the air flow flowing into the shell 1 through the air inlet structure can exchange heat with the heat exchanger 2 to realize the cooling of the heat exchanger 2.

[0036] It should be noted that the air intake structure in the present application includes the air inlet 101 at the top plate 11 to increase the total air intake area of the air conditioner outdoor unit 100, thereby enhancing the air volume of the air conditioner outdoor unit 100. By increasing the air volume, the heat exchange effect at the heat exchanger 2 is improved, and thus the energy efficiency of the air conditioner is enhanced.

[0037] That is to say, the air intake structure in the present application may also include air intake parts provided at other positions of the housing 1, such as: the air intake part provided at the back plate of the housing 1, the air intake part provided at the side plate of the housing 1, etc., to meet the air intake requirements of the air conditioner outdoor unit 100. That is to say, compared with the existing air conditioner outdoor unit, the air conditioner outdoor unit 100 in the present application is provided with an air inlet 101 at the top plate 11 of the housing 1 to increase the total air intake area of the housing 1.

[0038] It can be understood that when the total air intake area of the housing 1 increases, the air intake volume of the air conditioner outdoor unit 100 can be increased, the heat exchange effect at the heat exchanger 2 is improved, and thus the energy efficiency of the air conditioner is enhanced.

[0039] Combined Figure 1 and Figure 4 As shown, the heat exchanger 2 is arranged in the housing 1, and the heat exchanger 2 is disposed opposite to the air inlet 101. The air flow entering the housing 1 through the air inlet 101 can blow from the top of the heat exchanger 2 to the heat exchanger 2 and is discharged after flowing through the heat exchanger 2, so that the air volume at the heat exchanger 2 can be increased, the heat exchange efficiency at the heat exchanger 2 is improved, and thus the energy efficiency of the air conditioner is enhanced.

[0040] It can be understood that the air conditioner outdoor unit 100 is a part of the air conditioner. The air conditioner may further include an air conditioner indoor unit. The air conditioner indoor unit is provided with a drain pipe 200. One end of the drain pipe 200 is connected to the air conditioner indoor unit, and the other end of the drain pipe 200 can be arranged above the air conditioner outdoor unit 100. The water discharged through the drain pipe 200 can flow to the air inlet 101 to perform water cooling on the heat exchanger 2 and further improve the heat exchange effect at the heat exchanger 2.

[0041] Among them, when the air conditioner is in the cooling condition, the condensed water generated by the air conditioner indoor unit can be discharged through the drain pipe 200. Since the drainage end of the drain pipe 200 is arranged above the air inlet 101, the condensed water discharged through the drain pipe 200 can flow to the top of the air conditioner outdoor unit 100. The condensed water can be discharged to the heat exchanger 2 through the air inlet 101 to cool down the heat exchanger 2 by the condensed water, thereby further improving the heat exchange effect at the heat exchanger 2 and enhancing the energy efficiency of the air conditioner.

[0042] It should be noted that the temperature of the condensed water is usually in the range of 7°C - 12°C. That is to say, the temperature difference between the condensed water and the heat exchanger 2 of the outdoor unit 100 of the air conditioner is large, which can achieve a good water cooling effect, further improve the cooling effect at the heat exchanger 2, and thus improve the energy efficiency of the air conditioner. At the same time, after the condensed water drips on the heat exchanger 2, it will flow down along the heat exchanger 2 from top to bottom, enabling the condensed water to fully contact the heat exchanger 2 and improving the cooling effect at the heat exchanger 2 through the condensed water.

[0043] Therefore, the outdoor unit 100 in this application can also cooperate with the indoor unit of the air conditioner to utilize the condensed water generated during the refrigeration process of the indoor unit of the air conditioner to further improve the cooling effect at the heat exchanger 2 in the outdoor unit 100, and can achieve an improvement in the energy efficiency of the air conditioner.

[0044] Such as Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, in some embodiments of this application, the top plate 11 is provided with a flap 111. The flap 111 extends inward from the edge of the air inlet 101 towards the inside of the housing 1 to form a wind guiding structure at the air inlet 101 through the flap 111. The air flow entering through the air inlet 101 can flow towards the heat exchanger 2 under the guidance of the flap 111, enabling the air flow to fully contact the heat exchanger 2 and improving the heat exchange efficiency at the heat exchanger 2.

[0045] It can be understood that a fan 3 is also provided in the outdoor unit 100 of the air conditioner, and the fan 3 is arranged inside the housing 1. Driven by the fan 3, a pressure difference can be formed in the internal space of the housing 1, enabling the air outside the housing 1 to flow into the housing 1 through the air inlet structure, and taking away the heat of the heat exchanger 2 through the air flow to achieve the cooling of the heat exchanger 2.

[0046] In this application, a flap 111 structure that is folded inward is provided at the air inlet 101 of the top plate 11. A wind guiding structure is formed at the air inlet 101 through the flap 111. The wind guiding structure can guide the air flow entering the housing 1 through the air inlet 101 so that the air flow can blow towards the heat exchanger 2 and improve the heat exchange effect at the heat exchanger 2.

[0047] Refer to Figure 4 and Figure 5, in some embodiments of the present application, part of the heat exchanger 2 is opposite to and spaced apart from the flap 111, so as to form a flow passage for air flow between the heat exchanger 2 and the flap 111, ensuring the air flow effect at the air inlet, enabling the air flow to flow into the housing 1 from the flow passage defined between the heat exchanger 2 and the flap 111, allowing the air flow to fully carry away the heat at the heat exchanger 2, and improving the heat exchange efficiency at the heat exchanger 2. At the same time, the clearance fit between the flap 111 and the heat exchanger 2 can also reduce the assembly difficulty of the heat exchanger 2 and prevent interference between the heat exchanger 2 and the flap 111.

[0048] As Figure 6 shown, in a further embodiment of the present application, the flap 111 is arranged to surround the heat exchanger 2 in the circumferential direction, so as to form a flow passage surrounding the heat exchanger 2 in the circumferential direction through the cooperation between the flap 111 and the heat exchanger 2, enabling the air flow to fully contact the heat exchanger 2, enhancing the air flow effect at the heat exchanger 2, and thus improving the heat exchange efficiency at the heat exchanger 2.

[0049] As Figure 3 shown, in some embodiments of the present application, a connecting rib 112 is provided at the air inlet 101, and the connecting rib 112 is connected between two relatively arranged flaps 111 to enhance the structural strength at the air inlet 101 and the flap 111 and improve the anti-deformation ability at the flap 111.

[0050] It can be understood that the opening shape of the air inlet 101 is adapted to the top shape of the heat exchanger 2 to facilitate the correspondence between the heat exchanger 2 and the air inlet 101, fully increasing the air inlet area, so that the air flow entering through the air inlet 101 can blow towards the top of the heat exchanger 2. Among them, in the outdoor unit of an air conditioner, the heat exchanger 2 is usually arranged to extend along the length direction of the housing 1. When the opening shape of the air inlet 101 is adapted to the top shape of the heat exchanger 2, the length of the air inlet 101 is relatively long, resulting in weak strength at the air inlet 101.

[0051] In the present application, by providing the connecting rib 112 at the air inlet 101 and connecting the connecting rib 112 between two relatively arranged flaps 111, the structural strength at the air inlet 101 is improved to ensure the air inlet effect at the air inlet 101.

[0052] Referring to Figure 1 , it can be understood that by providing the connecting rib 112 at the air inlet 101, the air inlet 101 can be divided into multiple sub-air inlets through the connecting rib 112, so as to supply air to one side of the heat exchanger 2 through the multiple sub-air inlets.

[0053] It should be noted that the heat exchanger 2 is usually fixedly connected to the housing 1 through a mounting bracket. The connecting rib 112 is preferably arranged at a position corresponding to the mounting bracket to prevent the heat dissipation body of the heat exchanger 2 from being blocked by the connecting rib 112 and affecting the heat exchange efficiency of the heat exchanger 2.

[0054] As Figure 1 shown, in some embodiments of the present application, the outdoor unit 100 of the air conditioner further includes a fan 3, and the housing 1 is further provided with an air outlet 102. The air outlet 102 is arranged at the front plate of the housing 1, and the fan 3 is opposite to the air outlet 102 to send air out through the air outlet 102 and further discharge the hot air outwards.

[0055] Among them, further combined with Figure 2 shown, the heat exchanger 2 is usually arranged adjacent to the back plate of the housing 1, that is, behind the fan 3. The airflow generated when the fan 3 works can flow through the heat exchanger 2 and exchange heat with the heat exchanger 2 and then be discharged, so as to realize the cooling of the heat exchanger 2.

[0056] In some embodiments of the present application, the height dimension of the heat exchanger 2 corresponding to the flap 111 is L1, and the relational expression is satisfied: 1 mm ≤ L1 ≤ 5 mm.

[0057] Referring to Figure 4 , the height dimension of the heat exchanger 2 corresponding to the flap 111 is L1, which is also the overlapping area of the heat exchanger 2 and the flap 111 in the vertical direction. When L1 satisfies the above parameter range, part of the heat exchanger 2 can be embedded in the intake space defined by the flap 111, so that the heat exchanger 2 is fully corresponding to the intake port, ensuring that the airflow flowing into the housing 1 through the intake port is in full contact with the heat exchanger 2. Among them, L1 is preferably 2 mm.

[0058] As Figure 4 shown, in some embodiments of the present application, the vertical distance between the surface of the flap 111 opposite to the heat exchanger 2 and the heat exchanger 2 is L2, and the relational expression is satisfied: 0.5 ≤ L2 ≤ 2 mm.

[0059] Referring to Figure 4 , when the distance L2 between the flap 111 and the heat exchanger 2 satisfies the above parameter range, a flow channel for the airflow to pass through can be formed between the flap 111 and the heat exchanger 2. The airflow can further flow towards the inside of the housing 1 through the gap between the flap 111 and the heat exchanger 2, and the airflow can flow through the surface of the heat exchanger 2, further increasing the air flow velocity on the surface of the heat exchanger 2, thereby improving the heat exchange efficiency at the heat exchanger 2. Among them, L1 is preferably 1 mm.

[0060] It can be further understood that the top of the heat exchanger 2 can also be used to receive the condensed water discharged by the drain pipe 200. The condensed water can flow down along the surface of the heat exchanger 2. By arranging the flap 111 at an interval from the heat exchanger 2, a gap for the condensed water to flow down can be reserved between the flap 111 and the heat exchanger 2, so that the condensed water can flow down smoothly.

[0061] Combined with Figure 4 and Figure 5 As shown, in some embodiments of the present application, the air inlet 101 is arranged directly above the heat exchanger 2, and the flap 111 extends vertically from the opening edge of the air inlet 101 towards the inside of the housing 1 along the top plate 11, so as to arrange the flap 111 at a position suitable for cooperating with the heat exchanger 2.

[0062] Referring to Figure 5 , the flap 111 extends downward in the vertical direction, so that it can play a role in avoiding the heat exchanger 2, facilitating part of the heat exchanger 2 to extend into the air intake space defined by the flap 111, and preventing interference between the flap 111 and the heat exchanger 2. At the same time, the flap 111 can be arranged parallel to the side surface of the heat exchanger 2 arranged in the vertical direction to play a good guiding role for the air flow, so that the air flow can fully flow through the surface of the heat exchanger 2.

[0063] In a further embodiment of the present application, the flap 111 and the heat exchanger 2 are arranged with equal gaps, so as to facilitate the correspondence of the air intake space formed by the heat exchanger 2 and the flap 111, make the air flow flowing from the air inlet 101 to the heat exchanger 2 evenly distributed, and further improve the heat exchange effect at the heat exchanger 2.

[0064] Referring to Figure 5 , it should be noted that "arranged with equal gaps" means that the surface of the flap 111 opposite to the heat exchanger 2 is arranged parallel to the surface of the heat exchanger 2, that is, in the relative direction of the flap 111 and the heat exchanger 2, the distance between the flap 111 and the heat exchanger 2 is equal everywhere.

[0065] It should be noted that in the present application, the first direction is the length direction of the air conditioner outdoor unit 100, the second direction is the front-back direction of the air conditioner outdoor unit 100, and the third direction is the vertical direction of the air conditioner outdoor unit 100.

[0066] In some embodiments of the present application, in the projection of the air conditioner outdoor unit 100 in the vertical direction, the heat exchanger 2 is arranged in a straight line, and both the heat exchanger 2 and the air inlet 101 extend along the first direction, and the projection of the heat exchanger 2 falls within the projection of the air inlet 101, so as to arrange the heat exchanger 2 corresponding to the air inlet 101, increase the top air intake area of the housing 1, increase the overall air intake volume of the housing 1, and further improve the cooling effect at the heat exchanger 2.

[0067] It can be understood that the heat exchanger 2 being arranged in a straight line means that the heat exchanger 2 extends along the first direction, and also means that the heat exchanger 2 is arranged opposite to the back plate of the housing 1 in the second direction. Among them, the air inlet 101 is also configured to extend along the first direction, that is to say, the opening shape of the air inlet 101 is configured to be adapted to the shape of the heat exchanger 2 to ensure the corresponding effect between the air inlet 101 and the heat exchanger 2.

[0068] In some other embodiments of the present application, in the projection of the outdoor unit 100 of the air conditioner in the vertical direction, the heat exchanger 2 is arranged in an L shape, the air inlet 101 includes a first extension section 1011 extending along the first direction and a second extension section 1012 extending along the second direction, and the first extension section 1011 and the second extension section 1012 are arranged in an L shape, and the projection of the heat exchanger 2 falls within the projection of the air inlet 101.

[0069] Refer to Figure 2 , when the heat exchanger 2 is arranged in an L shape, part of the heat exchanger 2 is arranged opposite to the back plate, and the other part of the heat exchanger 2 is arranged opposite to the side plate. The projection of the air inlet 101 is also arranged in an L shape to correspond the air inlet 101 with the heat exchanger 2 and ensure the air inlet effect at the heat exchanger 2.

[0070] Among them, the air inlet 101 includes a first extension section 1011 and a second extension section 1012. The first extension section 1011 is formed on one side of the top plate 11 adjacent to the back plate, and the second extension section 1012 is formed on one side of the top plate 11 adjacent to the side plate. The first extension section 1011 and the second extension section 1012 can correspond to the heat exchanger 2 arranged in an L shape.

[0071] It should be noted that the arrangement form of the heat exchanger 2 is not limited to the straight line arrangement and the L shape arrangement mentioned above, and can also be a U shape arrangement with an opening facing forward and other forms. Correspondingly, the air inlet 101 can be configured into a shape adapted to the projection shape of the heat exchanger 2 in the vertical direction to ensure the air inlet effect at the top of the heat exchanger 2.

[0072] Among them, Figure 7 shows a comparative diagram of Comparative Example 1 of the air volume and noise of the outdoor unit of the air conditioner in the prior art solution and Example 1 of the air volume and noise of the outdoor unit 100 of the air conditioner in the embodiment of the present application.

[0073] As shown by Figure 7 , by arranging the air inlet 101 at the top plate 11, the air intake volume of the embodiment can be increased, and while improving the air inlet effect, the noise during the operation of the outdoor unit 100 of the air conditioner can also be reduced. By arranging the air inlet 101 at the top plate 11 of the outdoor unit 100 of the present application, the air intake volume of the outdoor unit 100 can be increased by 5% - 10%, thereby realizing the improvement of the energy efficiency of the air conditioner, and the noise can be reduced by 1 decibel - 2 decibels.

[0074] In summary, the outdoor unit 100 of the air conditioner according to the embodiments of the present application has at least the following advantages:

[0075] (1) In the outdoor unit 100 of the air conditioner, an air inlet 101 is added to the top plate 11, which improves the heat exchange effect at the top of the heat exchanger 2. At the same time, it can increase the total air inlet area of the air inlet structure formed by the housing 1 to increase the air inlet volume of the outdoor unit 100 of the air conditioner, thereby improving the energy efficiency of the air conditioner. At the same time, it can also reduce the noise generated during the operation of the outdoor unit 100 of the air conditioner.

[0076] (2) The flap 111 structure formed at the top plate 11 can cooperate with the heat exchanger 2, so that the air flow at the air inlet 101 can flow to the heat exchanger 2, improving the air flow velocity on the surface of the heat exchanger 2 to further improve the heat exchange effect at the heat exchanger 2.

[0077] (3) The air inlet 101 at the top plate 11 can correspond to the drain pipe 200 of the indoor unit of the air conditioner. The condensed water discharged through the drain pipe 200 can drip onto the top of the heat exchanger 2 through the air inlet 101, thereby further cooling the heat exchanger 2 through the condensed water and improving the heat exchange effect at the heat exchanger 2.

[0078] For the air conditioner according to the embodiments of the present application, the air conditioner includes the above-mentioned outdoor unit 100 of the air conditioner. The outdoor unit 100 of the air conditioner opens an air inlet 101 at the top plate 11 to send air to the heat exchanger 2 from the top of the heat exchanger 2, improving the heat exchange effect on the top of the heat exchanger 2, and increasing the overall air inlet volume of the outdoor unit 100 of the air conditioner, thereby improving the energy efficiency of the air conditioner.

[0079] In a further embodiment of the present application, the air conditioner further includes an indoor unit of the air conditioner. The indoor unit of the air conditioner is provided with a drain pipe 200. One end of the drain pipe 200 is connected to the indoor unit of the air conditioner, and the other end of the drain pipe 200 is arranged above the outdoor unit 100 of the air conditioner and is used for draining water to the air inlet 101 to drip condensed water onto the heat exchanger 2, further improving the cooling effect on the heat exchanger 2 through the condensed water and realizing the utilization of the condensed water.
