Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to an outdoor unit and an air conditioner. Background Technology

[0002] To improve heat dissipation, existing outdoor unit electrical control boxes utilize airflow channels formed within them. These channels, along with the compressor compartment, control box, and fan compartment, create a cooling airflow that removes heat from the control box. In conventional designs, the radiator is located on the fan side, while the electronic components are on the compressor side. The rotation of the fan in the fan compartment creates a pressure difference between the fan compartment and the compressor compartment, generating a cooling airflow from the compressor compartment through the control box to the fan compartment, thus carrying away the heat from the radiator.

[0003] However, because the radiator is located in the fan compartment, water in the fan compartment can easily flow from the radiator to the other side of the electronic components on the control board, causing short circuits and other issues on the control board. Utility Model Content

[0032] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0033] like Figures 1-6 As shown, this utility model provides an outdoor unit, which includes an outdoor unit housing 10, a partition 30, an electrical control box bottom plate 100, and an electrical control box cover 200. The partition 30 is disposed in the outdoor unit housing 10, dividing the outdoor unit housing 10 into a fan compartment 11 and a compressor compartment 12. A first ventilation hole is provided on the side wall of the fan compartment 11. The electrical control box bottom plate 100 includes a plate body 110 and a heat dissipation air outlet 120 connected to one end of the plate body 110. The plate body 110 is connected to the partition 30 and located in the compressor compartment 12. The heat dissipation air outlet 120 is disposed along the partition 30 and located in the fan compartment 11. The air inlet of the heat dissipation air outlet 120 communicates with the compressor compartment 12. A heat dissipation module 111 and a main control board 112 are disposed on the plate body 110. The control box cover 200 is placed on the control box base plate 100 and cooperates with the plate body 110 to form a heat dissipation air inlet 210, which is connected to the heat dissipation air outlet 120. The angle between the end face of the air outlet of the heat dissipation air outlet 120 and the partition 30 is greater than 0° and less than or equal to 90°.

[0034] The control box cover 200 is placed on the plate body 110, thus forming an electrical control box by placing the control box cover 200 on the control box base plate 100. The control box cover 200 and the plate body 110 can be connected by one or more methods such as screw connection or snap-fit ​​connection.

[0035] The outdoor unit typically includes a fan 50 and a compressor 40. The fan 50 is located in the fan compartment 11, and the compressor 40 is located in the compressor compartment 12. A heat dissipation duct is formed by connecting the heat dissipation inlet 210 and the heat dissipation outlet 120 to connect the fan compartment 11 and the compressor compartment 12. When the fan 50 rotates, it creates a negative pressure in the fan compartment 11, which in turn draws air from the compressor compartment 12 into the fan compartment 11 through the heat dissipation duct. When the air enters the heat dissipation duct, it performs airflow cooling on the heat dissipation module 111. At the same time, a first ventilation hole is provided on the side wall of the compressor compartment 12 to connect the compressor compartment 12 with the external environment, thereby ensuring that as the fan 50 starts, the external airflow will enter the compressor compartment 12, pass through the heat dissipation duct, and then enter the fan compartment 11 to ensure continuous heat dissipation for the heat dissipation module 111.

[0036] The plate body 110 has a plate-like structure and is flatly mounted on the partition 30. The heat dissipation module 111 and the main control board 112 are sequentially arranged on the plate body 110 along its length. The heat dissipation module 111 is positioned close to the heat dissipation outlet 120 to facilitate airflow for heat dissipation. Furthermore, the heat dissipation module 111 and the main control board 112 are located on the same side of the partition 30, which simplifies the soldering difficulty of the heat dissipation module 111 and saves soldering time.

[0037] The air inlet of the heat dissipation air outlet 120 is generally located on the partition 30, and can be located in the compressor compartment 12.

[0038] Among them, the heat dissipation air inlet 210 formed by the electrical control box cover 200 and the board body 110 has its air outlet connected to the air inlet of the heat dissipation air outlet 120, and the air inlet of the heat dissipation air inlet 210 is connected to the compressor compartment 12. That is, by rotating the fan 50, a negative pressure is formed in the fan compartment 11, which in turn drives the airflow in the compressor compartment 12 to enter the fan compartment 11 through the heat dissipation air inlet 210 and the heat dissipation air outlet 120.

[0039] Referring to the attached drawing, the angle between the air outlet end face of the heat dissipation air outlet 120 and the partition plate 30 is α.

[0040] It should be noted that the angle between the end face of the air outlet of the heat dissipation air outlet 120 and the partition 30 is greater than 0° and less than or equal to 90°, which means that the air outlet of the heat dissipation air outlet 120 is set towards the bottom of the outdoor unit or the partition 30. At the same time, since the heat dissipation air outlet 120 is set along the partition 30, the heat dissipation air outlet 120 as a whole has a certain length, and the port is relatively hidden or blocked by the outer wall of the heat dissipation air outlet 120, so as to prevent condensate water from entering the heat dissipation air outlet 120 along the splash path, thereby preventing condensate water from splashing into the electrical control box.

[0041] Therefore, it is understandable that the outdoor unit uses a partition 30 to divide the interior of the outdoor unit into a fan compartment 11 and a compressor compartment 12. The heat dissipation module 111 and the main control board 112 are both set on the plate body 110 of the bottom plate 100 of the electrical control box, and the plate body 110 is set on the side of the partition 30 located in the compressor compartment 12. The air inlet of the heat dissipation air outlet 120 of the bottom plate 100 of the electrical control box is connected to the compressor compartment 12, and the heat dissipation air outlet 120 is located in the fan compartment 11. At the same time, the angle between the end face of the air outlet of the heat dissipation air outlet 120 and the partition 30 is greater than 0° and less than or equal to 90°, so that the end face of the air outlet of the heat dissipation air outlet 120 faces the bottom wall of the outdoor unit housing 10 or the partition 30, so as to prevent the condensate in the fan compartment 11 from splashing into the heat dissipation air outlet 120, thereby protecting the main control board 112 and preventing the main control board 112 from short-circuiting.

[0042] In some embodiments, the control box cover 200 may completely or partially cover the panel portion 110.

[0043] In some embodiments, the heat dissipation module 111 is disposed on the main control board 112 and is disposed near the top of the main control board 112.

[0044] In some embodiments, the heat dissipation air outlet 120 includes a first bottom wall 122 and a first top cover 121 connected thereto. The first bottom wall 122 includes a first sub-wall 1221 and a second sub-wall 1222 connected in sequence. The first sub-wall 1221 passes through the partition 30, and the second sub-wall 1222 is arranged along the partition 30. The side of the first sub-wall 1221 near the top of the outdoor unit is inclined to form a water guide surface 1220. The end of the water guide surface 1220 near the compressor compartment 12 is higher than the end of the water guide surface 1220 near the fan compartment 11.

[0045] The first top cover 121 is mounted on the first bottom wall 122 and cooperates with the first bottom wall 122 to form a heat dissipation outlet 120.

[0046] The first sub-wall 1221 is installed on the partition 30, and the angle between the first sub-wall 1221 and the partition 30 is greater than or equal to 90° and less than or equal to 135°. Generally, the first sub-wall 1221 is arranged perpendicular to the partition 30, that is, the angle between the first sub-wall 1221 and the partition 30 is 90°.

[0047] The second sub-wall 1222 is arranged along the partition 30, that is, the second sub-wall 1222 is arranged parallel to the partition 30.

[0048] It is understandable that the first sub-wall 1221 is inclined to form a water guide surface 1220 near the top of the outdoor unit, so that the end of the water guide surface 1220 near the compressor compartment 12 is higher than the end of the fan compartment 11. This allows the water guide surface 1220 to block the condensate entering the heat dissipation air outlet 120. The slope structure formed by the water guide surface 1220 allows the condensate entering the heat dissipation air outlet 120 to flow back to the fan compartment 11 along the water guide surface 1220.

[0049] In some embodiments, a water-blocking rib 130 is also provided on the side of the water guide surface 1220 near the compressor compartment 12, and the water-blocking rib 130 is provided along the width direction of the first sub-wall 1221.

[0050] It is understandable that by setting a water-blocking rib 130 on the side of the water guide surface 1220 close to the compressor compartment 12, the splashing condensate water that crosses the water guide surface 1220 can be blocked, preventing it from entering the electrical control part of the compressor compartment 12 and preventing the main control board 112 from short-circuiting.

[0051] In some embodiments, the two side walls of the plate portion 110 are respectively provided with flow guiding channels 140, and the two ends of the water guiding surface 1220 are respectively provided with flow inlets (not shown), and each flow inlet (not shown) is connected to a flow guiding channel 140.

[0052] The plate body 110 has a groove-shaped structure in its side wall, which is the guide channel 140. The condensate on the water guide surface 1220 is guided to the guide channel 140 through the guide port (not shown), and then discharged from the bottom plate 100 of the electrical control box through the guide channel 140.

[0053] It is understandable that when the slope of the water guide surface 1220 is small, although the water baffle 130 blocks the condensate, the condensate cannot be discharged quickly due to the small slope of the water guide surface 1220. By setting drainage ports (not shown) at both ends of the water guide surface 1220, the condensate can be discharged quickly from the bottom plate 100 of the electrical control box.

[0054] In some embodiments, one end of the water-blocking rib 130 cooperates with the first top cover 121 to form a drainage port (not shown).

[0055] The first top cover 121 includes a top cover portion and a side wall portion, and one end of the water-blocking rib 130 is spaced apart from the side wall portion to form a drainage port (not shown).

[0056] In some embodiments, the water guide surface 1220 is further provided with a diversion channel (not shown) at both ends. The diversion channel (not shown) is opened on the first bottom wall 122 and the second bottom wall. The condensate on the water guide surface 1220 is quickly discharged from the heat dissipation outlet 120 through the diversion channel (not shown) so that it flows back to the fan compartment 11.

[0057] In some embodiments, the first sub-wall 1221 is inclined, with the end of the first sub-wall 1221 near the compressor compartment 12 being higher than the end of the first sub-wall 1221 near the fan compartment 11.

[0058] It is understood that in this embodiment, the first sub-wall 1221 is directly inclined, thereby making the side of the first straight wall near the top of the outdoor unit housing 10 inclined to form a water guiding surface 1220.

[0059] In some embodiments, the water guide surface 1220 is a stepped surface formed by multiple water guide sub-surfaces, each water guide sub-surface is inclined, and the end of the water guide sub-surface near the compressor compartment 12 is higher than the end of the water guide sub-surface near the fan compartment 11.

[0060] It is understandable that by setting the water guiding surface 1220 as a stepped surface, the vertical height of the water guiding surface 1220 is increased, thereby forming a water-blocking structure and improving the water-blocking capacity of the water guiding surface 1220.

[0061] In some embodiments, the heat dissipation vent 120 and the plate body 110 are spaced apart to form a hanging part 150, and the bottom plate 100 of the electrical control box is hung on the partition 30 through the hanging part 150.

[0062] A mounting notch can be provided at the top of the partition 30, and the bottom plate 100 of the electrical control box can be mounted on the partition 30 by the mounting notch cooperating with the mounting part 150.

[0063] Alternatively, a mounting hole can be provided in the middle of the partition 30, so that after the heat dissipation exhaust part 120 passes through the mounting hole, the mounting part 150 is matched with the mounting hole to hang the bottom plate 100 of the electrical control box on the partition 30.

[0064] In some embodiments, the heat dissipation module 111 is located on top of the main control board 112, and the orthographic projection of the electrical control box cover 200 on the board body 110 at least completely covers the heat dissipation module 111.

[0065] The orthographic projection of the control box cover 200 onto the board body 110 completely covers the heat dissipation module 111, that is, the control box cover 200 at least blocks the heat dissipation module 111.

[0066] In some embodiments, the control box cover 200 covers the main control board 112 together, that is, the orthogonal projection of the control box cover 200 on the board body 110 completely covers the heat dissipation module 111 and the main control board 112.

[0067] In some embodiments, the present invention also provides an air conditioner that includes the outdoor unit described above. Since the air conditioner includes the outdoor unit described above, that is, includes some or all of the embodiments of the outdoor unit described above, the air conditioner has the beneficial effects of some or all of the embodiments of the outdoor unit described above, which will not be described in detail here.

[0068] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made based on the contents of the present utility model specification and drawings under the application concept of the present utility model, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
