Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and more specifically, to an outdoor unit of an air conditioner and an air conditioner having the same. Background Technology

[0002] During the operation of an air conditioner, functions such as compressor and fan operation, as well as signal transmission between indoor and outdoor units, are all controlled by the main board of the outdoor unit. Therefore, there are many components on the surface of the main board. These components generate a lot of heat when the air conditioner is running, so a heat dissipation structure needs to be set on the electrical box to dissipate heat from the main board.

[0003] The heat dissipation strategies for air conditioner outdoor units mainly include adding radiators and improving ventilation channel design. For example, by installing radiators on the electrical box, heat is carried away by airflow to achieve the purpose of heat dissipation. However, due to the limitations of radiator placement and ventilation channels, the airflow through the radiators is often insufficient, failing to efficiently reduce the internal temperature of the electrical box.

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] Please refer to Figures 1 to 13 As shown, this application provides an outdoor unit for an air conditioner, including an outdoor unit body 100, an electrical box 200, and a control main board 300. A partition 110 is provided inside the outdoor unit body 100 to divide it into a first chamber 101 and a second chamber 102. The electrical box 200 is disposed on the partition 110, and the control main board 300 is disposed inside the electrical box 200 and faces the first chamber 101. A fan assembly 400 is disposed in the second chamber 102. A first gap 301 is provided between the control main board 300 and the electrical box 200. The outdoor unit also includes a first air inlet 500 disposed on the outdoor unit body 100. The first chamber 101 is connected to the second air inlet 500; the second air inlet 600 is disposed on the side plate 210 of the electrical box 200, and extends along the circumferential direction of the side plate 210, and is connected to the first partition 301; the air outlet 700 is disposed at least partially on the bottom plate 220 of the electrical box 200, and is connected to the first partition 301 and the second chamber 102 respectively, so that under the guidance of the fan assembly 400, the outdoor airflow passes through the first air inlet 500, the second air inlet 600 and the air outlet 700 to dissipate heat on the electrical box 200 and the control board 300.

[0040] According to the outdoor unit of the air conditioner provided in this application, the first air inlet 500 increases the amount and velocity of air entering the outdoor unit. In the second air inlet 600, the air directly acts on the side plate 210 of the electrical box 200, which can effectively remove the heat generated by the control board 300 during operation, avoiding performance degradation or damage to components due to overheating. At the same time, the presence of the first gap 301 further optimizes the airflow within the electrical box 200, making heat dissipation more thorough.

[0041] By setting the air outlet 700 on the base plate 220 of the electrical box 200 and communicating with the first partition 301 and the second chamber 102, not only is effective heat dissipation of the electrical box 200 and the control board 300 ensured, but also the airflow is diverted by the fan assembly 400 so that the hot air passing through the electrical box 200 can be directly discharged to the second chamber 102, further helping the first chamber 101 to dissipate heat, thus achieving overall system heat exchange optimization.

[0042] Specifically, the first air inlet 500 includes: a plurality of air inlets 510 disposed on the outdoor unit 100, the plurality of air inlets 510 being spaced apart along the height direction of the outdoor unit 100; each air inlet 510 being connected to the first chamber 101 so that outdoor airflow flows into the first chamber 101 through each air inlet 510.

[0043] The arrangement of multiple air inlets 510 significantly increases the volume and velocity of the outdoor airflow entering the first chamber 101 compared to a single air inlet, thereby improving the heat dissipation efficiency of the outdoor unit. Since the air inlets 510 are spaced apart along the height of the outdoor unit 100, the incoming air can form a more uniform flow distribution within the first chamber 101, which helps to evenly dissipate heat from critical components such as the compressor and the mainboard inside the electrical box.

[0044] In the embodiments provided in this application, such as Figures 1 to 4 As shown, the outdoor unit 100 includes a first plate 121 and a second plate 122 connected to each other, with an included angle between the first plate 121 and the second plate 122. At least a portion of the second plate 122 is connected to the condenser 130. The first air inlet 500 includes: a first air inlet 511 disposed at the top of the first plate 121; and a second air inlet 512 disposed at the bottom of the second plate 122. The second air inlet 512 and the first air inlet 511 are respectively connected to the first chamber 101. The second air inlet 512 extends along the width direction of the second plate 122. There are multiple second air inlets 512, which are spaced apart along the height direction of the second plate 122. The width of each second air inlet 512 is 1mm to 2mm.

[0045] The design of the first air inlet 511 and multiple second air inlets 512 enables the introduction of outdoor air from the top and bottom in multiple directions, increasing the airflow into the first chamber 101. This helps to improve the heat dissipation efficiency of the compressor and electrical box 200, especially in high-temperature environments, and can more effectively reduce the internal temperature of the equipment, ensuring stable operation of the equipment.

[0046] The second air inlet 512 extends along the width of the second plate 122, and multiple second air inlets 512 are spaced apart along the height of the second plate 122. This method optimizes the airflow distribution, allowing air to enter the first chamber 101 more evenly. By limiting the width of the second air inlet 512 to 1mm to 2mm, not only can sufficient air volume be introduced, but the risk of rainwater directly entering the first chamber 101 can also be reduced to a certain extent. This improves the waterproof performance of the outdoor unit of the air conditioner in rainy seasons or humid environments, thereby enhancing the overall safety and service life of the equipment.

[0047] The outdoor unit of the air conditioner also includes: a handle component 800, which is disposed on the first plate 121 and opposite to the first air inlet 511. The handle component 800 has an operating section 810, and the operating section 810 has a third air inlet 811. A fourth air inlet 820 is disposed on the bottom surface of the handle component 800. The third air inlet 811 and the fourth air inlet 820 are respectively connected to the first air inlet 511. By providing the fourth air inlet 820 on the bottom surface of the handle, not only is direct rainwater flow from above prevented, but the handle structure also blocks rainwater and dust entering from the side or bottom, protecting internal components and improving the reliability and service life of the equipment.

[0048] The placement of the third air inlet 811 and the fourth air inlet 820 directly increases the airflow into the outdoor unit of the air conditioner. In particular, the third air inlet 811 on the operating section 810, being typically positioned higher than the first air inlet 511 on the first plate 121, can introduce more and fresher air. After entering through the third air inlet 811 and the fourth air inlet 820, the airflow merges with the airflow from the first air inlet 511, ensuring that the airflow can effectively pass through the control main board 300 and the electrical box 200, thus enhancing the heat dissipation effect.

[0049] like Figure 5As shown, in this application, the side plate 210 includes a first side plate 211, a second side plate 212, and a third side plate 213. The first side plate 211, the second side plate 212, and the third side plate 213 are connected sequentially along the circumferential direction of the bottom plate 220. The second side plate 212 is disposed facing the bottom surface of the first chamber 101. The second air inlet 600 includes: a plurality of first air inlet channels 610, each of which is disposed on the first side plate 211; a plurality of second air inlet channels 620, each of which is disposed on the second side plate 212; and a plurality of third air inlet channels 630, each of which is disposed on the third side plate 213. The first air inlet channel 610, the second air inlet channel 620, and the third air inlet channel 630 are respectively connected to the first interval 301.

[0050] By placing air intake channels on different parts of the side panel 210, namely the first side panel 211, the second side panel 212, and the third side panel 213, outdoor air can be introduced from different angles, achieving all-round heat dissipation around the electrical box 200. This effectively reduces the local high temperature of the control motherboard 300. In addition, the design of multiple air intake channels significantly increases airflow. Air entering through the air intake channels on different side panels can converge in the first interval 301, improving heat dissipation efficiency. By setting air intake channels in multiple locations on the side panel 210, direct openings on the front or top of the electrical box 200 can be avoided, reducing the risk of rainwater and dust directly entering the interior of the electrical box. This enhances the waterproof and dustproof performance of the equipment, improving its stability and reliability.

[0051] The partition 110 is provided with a wire-passing part 111, and the first side plate 211 is located at one end close to the wire-passing part 111; the outdoor unit of the air conditioner also includes: a water-blocking part 230, which is provided on the first side plate 211. The water-blocking part 230 protrudes relative to the surface of the first side plate 211 and surrounds the first air inlet channel 610.

[0052] The partition 110 is also provided with a ventilation grille 113. The airflow in the first chamber 101 flows directly into the second chamber 102 through the ventilation grille 113. The ventilation grille 113 is located below the wire passage 111. The water vapor in the second chamber 102 can flow into the side of the partition 110 facing the first chamber 101 through the ventilation grille 113. Therefore, the water-blocking part 230 is provided on the first side plate 211 to prevent water on the partition 110 from entering the electrical box 200 through the first air inlet channel 610.

[0053] The design of the water-blocking part 230 can effectively prevent water droplets or water flow on the partition 110 from entering the electrical box 200 through the first air inlet channel 610. Especially when rainwater flows along the partition 110, the protruding structure of the water-blocking part 230 plays a key blocking role, protecting the control board 300 inside the electrical box 200 from water damage, significantly enhancing the waterproof performance of the equipment, reducing the risk of short circuit inside the electrical box 200, and reducing the frequency of equipment maintenance.

[0054] In the embodiments provided in this application, such as Figures 6 to 9 As shown, a heat dissipation fin 240 is provided on the side of the base plate 220 away from the control main board 300. The heat dissipation fin 240 is positioned towards the second chamber 102. A protective plate 250 is also provided on the base plate 220, which surrounds the heat dissipation fin 240. At least a portion of the base plate 220 has a second gap 112 between it and the partition 110. The air outlet 700 includes a first air outlet 710 and a second air outlet 720. The first air outlet 710 is disposed on the base plate 220, and the second air outlet 720 is disposed on the protective plate 250. The first air outlet 710 communicates with the first gap 301 so that the airflow in the first gap 301 flows into the second gap 112 after passing through the first air outlet 710, and then flows out of the outdoor unit 100 after passing through at least a portion of the second air outlet 720 and the heat dissipation fin 240.

[0055] The heat dissipation fins 240 are positioned towards the second chamber 102, enabling them to directly absorb heat from the control motherboard 300 and quickly dissipate it through heat exchange with the airflow within the second chamber 102. Compared to simple natural air convection, this design significantly enhances heat dissipation and reduces the internal temperature of the device. The first air outlet 710 is connected to the first partition 301, guiding the hot air passing through the first partition 301 of the control motherboard 300 towards the second partition 112, rather than allowing it to disperse randomly. This ensures that the hot air can efficiently flow through the area of ​​the heat dissipation fins 240 for heat exchange.

[0056] The protective plate 250 not only protects the heat dissipation fins 240 from physical damage, but also serves as a waterproofing measure, preventing rainwater or water droplets from falling directly onto the heat dissipation fins 240 when humidity is too high, thus affecting heat dissipation performance or causing corrosion, and ensuring the stable operation and long-term durability of the equipment.

[0057] In specific implementation, the first air outlet 710 includes a first air outlet channel 711, which is located at the top of the base plate 220. The first air outlet channel 711 is arranged towards the second interval 112 and is connected to the second interval 112. There are multiple first air outlet channels 711, which are arranged at intervals.

[0058] The design of multiple first air outlet channels 711 can significantly improve heat dissipation efficiency. Through the multiple air outlet channels on the top of the base plate 220, the hot air in the first interval 301 can flow out faster and more evenly, accelerating the heat exchange between the hot air and the external environment, which helps to reduce the temperature of the electrical box 200 and the control motherboard 300.

[0059] The protective plate 250 includes a first protective plate body 251 and a second protective plate body 252 disposed on both sides of the heat dissipation fins 240, with at least a portion of the second protective plate body 252 facing the second interval 112; the second air outlet 720 includes: a second air outlet channel 722 disposed on the first protective plate body 251, the second air outlet channel 722 communicating with the first chamber 101, the airflow in the first chamber 101 flowing through the second air outlet channel 722 and then through the heat dissipation fins 240 to dissipate heat from the heat dissipation fins 240; and a third air outlet channel 723 disposed on the second protective plate body 252, the third air outlet channel 723 communicating with the second interval 112, the airflow in the second interval 112 being blown to the surface of the heat dissipation fins 240 through the third air outlet channel 723.

[0060] The design of the second air outlet duct 722 and the third air outlet duct 723 ensures that the airflow from the first chamber 101 and the second partition 112 can directly blow on the heat dissipation fins 240, thereby enhancing the heat exchange process and improving heat dissipation efficiency. The hot air in the first chamber 101 is blown to the heat dissipation fins 240 through the second air outlet duct 722, accelerating the heat transfer of heat-generating components such as the compressor, while the airflow in the second partition 112 further enhances the cooling effect of the heat dissipation fins 240 through the third air outlet duct 723.

[0061] This application also provides an air conditioner, including an outdoor unit and an indoor unit, wherein the outdoor unit is the same as the outdoor unit described in the above embodiment.

[0062] The outdoor unit of the air conditioner mainly consists of a condenser 130, a motor bracket, a fan assembly 400, an electrical box 200, a partition 110, and a compressor 900. The partition 110 divides the outdoor unit into two chambers: a first chamber 101 and a second chamber 102. The fan assembly 400 is located in the second chamber 102, and the compressor 900 is located in the first chamber 101. The electrical box 200 is vertically mounted on the partition 110. When the outdoor unit is operating, the compressor 900 generates a large amount of heat. Simultaneously, the control board 300 within the electrical box 200 also generates heat due to the operation of its surface components. Therefore, an air vent is installed on the right side panel to allow ambient temperature air to enter the compressor chamber and then dissipate heat through the radiator in the electrical box 200 and the partition 110.

[0063] like Figure 3 and Figure 4As shown, to increase the amount of outdoor air entering the first chamber 101, two air inlets are considered. The first air inlet is located on the second plate 122, and this inlet consists of several small strip-shaped vents. Considering that if the vent is too large, rainwater will enter the first chamber 101, and if the vent is too small, there will not be enough air entering the chamber, the width of each vent is specified to be 1-2 mm. The other air inlet is located on the handle component 800. Not only does the handle have a grid-like opening at the stress point, but there is also a grid-like opening below the handle separated by ribs. The distance between the ribs is set to be 1-2 mm, which can both increase the airflow and prevent rainwater from flowing into the chamber during rain.

[0064] pass Figures 5 to 9 You can observe the external schematic diagram and air inlet diagram of the electrical box 200 component. This component consists of the electrical box 200, the control main board 300, and the heat sink fins 240. The control main board 300 contains several components. After the electrical box 200 is placed vertically, from... Figure 7 The first air intake channel 610 can be observed. It consists of several small rectangular air vents, with lengths and widths a and b, where a ranges from 8mm to 15mm and b ranges from 2mm to 4mm. In addition to the air intake channel on the first side plate 211 of the electrical box 200, air intake channels are also provided on the second side plate 212 and the third side plate 213. These structures ensure that air can pass through the surface of the control motherboard 300 and enter the first gap 301 inside the electrical box 200, carrying away heat from the back of the control motherboard 300.

[0065] pass Figures 5 to 9 You can see the air outlet on the electrical box 200. The first air outlet channel 711 is located above the electrical box 200, allowing air inside the electrical box 200 to exit. After exiting, some of the air passes through the third air outlet channel 723 and then flows over the heat dissipation fins 240. The main function of the second air outlet channel 722 is to allow the hot air in the first chamber 101 to flow directly out from here, passing through the heat dissipation fins and carrying away the heat generated by the compressor 900.

[0066] In summary, such as Figures 10 to 14 As shown, the airflow path inside the outdoor unit is divided into:

[0067] Flow path ①: After passing through the first chamber 101, outdoor air is directly blown onto the heat dissipation fins through the second air outlet 722;

[0068] Flow path ②, the airflow in the first chamber 101 is blown toward the heat dissipation fins through the ventilation grille 113 on the partition 110 and the third air outlet channel 723;

[0069] Flow path ③: The airflow in the first chamber 101 flows directly into the second chamber 102 through the ventilation grille 113;

[0070] Flow path ④: After passing through the first air outlet channel 711 and the ventilation grille 113, the airflow in the first chamber 101 flows into the second chamber 102;

[0071] Flow path ⑤: After the airflow in the first chamber 101 passes through the first air inlet channel 610, the first air outlet channel 711 and the third air outlet channel 723, it blows towards the heat dissipation fins.

[0072] In flow path ⑥, after the airflow in the first chamber 101 flows into the first interval 301, part of it flows back into the first chamber 101 through the channel on the third side plate 213, and then blows onto the heat dissipation fins through the second air outlet channel 722.

[0073] A rainproof structure, which is a strip-shaped protrusion, is added to the first side plate 211 of the electrical box 200. In order to effectively prevent water from entering the first chamber 101 from the opening on the surface of the partition 110, the protrusion is 2.5mm to 7mm high and 0.5mm to 2mm wide. This method will not obstruct the airflow.

[0074] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0075] According to the outdoor unit of the air conditioner provided in this application, the first air inlet 500 increases the amount and velocity of air entering the outdoor unit. In the second air inlet 600, the air directly acts on the side plate 210 of the electrical box 200, which can effectively remove the heat generated by the control board 300 during operation, avoiding performance degradation or damage to components due to overheating. At the same time, the presence of the first gap 301 further optimizes the airflow within the electrical box 200, making heat dissipation more thorough.

[0076] By setting the air outlet 700 on the base plate 220 of the electrical box 200 and communicating with the first partition 301 and the second chamber 102, not only is effective heat dissipation of the electrical box 200 and the control board 300 ensured, but also the airflow is diverted by the fan assembly 400 so that the hot air passing through the electrical box 200 can be directly discharged to the second chamber 102, further helping the first chamber 101 to dissipate heat, thus achieving overall system heat exchange optimization.

[0077] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
