The electric control box comprises an electric control box cover made of a heat dissipation material, and the electric control box cover has a circular arc concave surface. When the electric control box is installed in the air conditioner, the circular arc concave surface on the electric control box cover can face the outdoor side fan of the air conditioner, so that the heat dissipation effect of the electric control box is achieved. The circular arc concave surface can make the airflow flowing on the electric control box cover contact more surfaces of the electric control box, so that the heat dissipation effect of the airflow on the electric control box is further improved. In addition, the circular arc concave surface on the electric control box cover can also face the water beating ring of the air conditioner, so that the water in the water beating ring can flow to the circular arc concave surface and flow back and forth on the circular arc concave surface, thereby continuously dissipating heat from the electric control box. Meanwhile, the electric control box cover is also made of a heat dissipation material, so that when the outdoor side fan and / or the water beating ring dissipate heat from the electric control box cover, the heat dissipation efficiency of the electric control box can be further improved.

Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more particularly to an electrical control box and an air conditioner. Background Technology

[0002] Nowadays, as the country's requirements for air conditioner energy efficiency become increasingly stringent, high-efficiency air conditioners often have a greater advantage. At the same time, due to users' demand for air conditioners that can be used for both cooling and heating, high-efficiency inverter air conditioners are highly favored by users.

[0003] However, due to the dual functions of high energy efficiency and inverter technology, the air conditioner's electrical control box generates significant heat. If the heated electrical control box cannot dissipate heat properly, it will not only affect the air conditioner's cooling or heating performance, but may also cause serious safety issues such as fires due to poor heat dissipation. Summary of the Invention

[0004] This application provides an electrical control box and an air conditioner to solve the problem that the electrical control box of existing air conditioners overheats and cannot dissipate heat well during operation.

[0005] In a first aspect, embodiments of this application provide an electronic control box, comprising:

[0006] The electrical control box cover is made of heat-dissipating material;

[0007] The cover of the electrical control box has a concave arc surface.

[0008] When the electrical control box is installed inside the air conditioner, the concave arc surface faces the outdoor fan and / or water jet of the air conditioner.

[0009] Optionally, the air conditioner further includes at least one heat exchanger, and the electrical control box is disposed between the outdoor fan and the heat exchanger, and located at the top of the air conditioner.

[0010] Optionally, the air conditioner further includes a water collection tray, which is disposed at the bottom of the electrical control box. The water-discharging ring is disposed around the periphery of the outdoor fan. The water-discharging ring has a protrusion and a recess in the direction of rotation of the water-discharging ring. The arc-shaped concave part is positioned opposite the recess. When the protrusion rotates with the water-discharging ring and passes the water collection tray, the recess can carry some condensate. When the protrusion rotates to the arc-shaped concave part, the condensate can be discharged from the recess.

[0011] Optionally, the control box further includes a base, and the control box cover is disposed on the base to form an accommodating space. The control box cover includes a first air inlet surface and a first heat dissipation surface. The first air inlet surface is disposed on one side of the control box cover, and the first heat dissipation surface extends in a direction away from the first air inlet surface. The first heat dissipation surface has a continuous curved surface structure, and the first air inlet surface is provided with a first groove. The air outlet of the first groove faces the first heat dissipation surface.

[0012] Optionally, the electrical control box cover further includes a second heat dissipation surface, which extends in a direction away from the first air inlet surface, and the first air inlet surface, the first heat dissipation surface and the second heat dissipation surface are arranged adjacent to each other. The first groove is disposed on the side of the first air inlet surface near the second heat dissipation surface, and the end of the first groove near the second heat dissipation surface is disposed towards the first heat dissipation surface.

[0013] Optionally, the first groove is S-shaped, and the angle between the end of the first groove near the second heat dissipation surface and the first heat dissipation surface is 45° to 60°.

[0014] Optionally, both the first heat dissipation surface and the second heat dissipation surface are provided with a second groove, the second groove extending away from the first air inlet surface, wherein the second groove on the second heat dissipation surface is connected to the first groove.

[0015] Optionally, the electrical control box cover further includes a third heat dissipation surface and a fourth heat dissipation surface that are adjacent to each other. The third heat dissipation surface and the fourth heat dissipation surface are disposed on the side of the first heat dissipation surface away from the first air inlet surface. The third heat dissipation surface is adjacent to the first heat dissipation surface and the second heat dissipation surface, and the third heat dissipation surface also protrudes in a direction away from the first heat dissipation surface. The third heat dissipation surface has a third groove, and the fourth heat dissipation surface has a fourth groove on the side close to the third heat dissipation surface. One end of the third groove is connected to the fourth groove, and the other end extends toward the first heat dissipation surface.

[0016] Optionally, the end of the electrical control box cover away from the fourth heat dissipation surface is also provided with a chamfer structure. The chamfer structure is used to compress the volume of the accommodating space to accelerate the airflow speed in the accommodating space.

[0017] Optionally, the arc-shaped concave portion protrudes from the fourth heat dissipation surface. The arc-shaped concave portion includes an arc surface and a fifth groove disposed on the arc surface. The fifth groove is disposed along the length direction of the arc surface and communicates with the second groove located on the second heat dissipation surface.

[0018] Optionally, the electrical control box cover is also provided with an installation port, which is located on the side away from the first air inlet surface. The electrical control box also includes multiple fins, which are spaced apart at the installation port so that a gap is formed between each pair of fins, allowing air to enter the receiving space through the installation port and the gap.

[0019] Secondly, embodiments of this application also provide an air conditioner, comprising:

[0020] case;

[0021] The electrical control box as described in any of the above claims is disposed within the housing.

[0022] The electrical control box provided in this application includes a cover made of heat-dissipating material. The cover has a concave arc surface. When the electrical control box is installed inside an air conditioner, the concave arc surface of the cover faces the outdoor fan of the air conditioner. This allows the negative pressure generated by the outdoor fan during air conditioner operation to drive airflow inside the air conditioner, bringing the airflow into contact with the cover for heat dissipation. The concave arc surface also allows the airflow to contact a larger portion of the control box surface, further improving the heat dissipation effect by increasing the heat exchange area between the airflow and the control box. Additionally, the concave arc surface of the cover can also face the condensation ring of the air conditioner, allowing water from the condensation ring to flow to and circulate on the concave arc surface for continuous heat dissipation of the control box. Meanwhile, since the cover of the electrical control box is also made of heat-dissipating material, the heat dissipation efficiency of the electrical control box can be further improved when the outdoor fan and / or water jet ring dissipate heat from the cover.

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0037] Nowadays, as the country's requirements for air conditioner energy efficiency become increasingly stringent, high-efficiency air conditioners often have a greater advantage. At the same time, due to users' demand for air conditioners that can be used for both cooling and heating, high-efficiency inverter air conditioners are highly favored by users.

[0038] However, due to the dual functions of high energy efficiency and inverter technology, the air conditioner's electrical control box generates significant heat. If the heated electrical control box cannot dissipate heat properly, it will not only affect the air conditioner's cooling or heating performance, but may also cause serious safety issues such as fires due to poor heat dissipation.

[0039] Based on the above-mentioned technical problems, this application provides an electronic control box 100. Please refer to [link / reference]. Figures 1-3 , Figure 1 This is a schematic diagram of the overall structure of the air conditioner provided in the embodiments of this application. Figure 2 for Figure 1 The diagram shown is a structural schematic of the air conditioner after the casing has been concealed. Figure 3 This is a front view of the electrical control box provided in an embodiment of this application.

[0040] In this embodiment, the control box 100 includes a control box cover 120 made of heat dissipation material. The control box cover 120 has an arc-shaped concave surface 127. When the control box 100 is installed inside the air conditioner 200, the arc-shaped concave surface 127 on the control box cover 120 can face the outdoor fan 211 of the air conditioner 200. This allows the negative pressure generated by the rotation of the outdoor fan 211 when the air conditioner 200 is running to allow the airflow inside the air conditioner 200 to flow and bring the airflow into contact with the control box cover 120 to dissipate heat from the control box 100. The arc-shaped concave surface 127 allows the airflow flowing on the control box cover 120 to contact more of the surface of the control box 100, and further improves the heat dissipation effect of the airflow on the control box 100 by increasing the heat exchange area between the airflow and the control box 100.

[0041] Additionally, please combine Figure 4 , Figure 4 This is a schematic diagram of the assembly structure of the outdoor fan and water jet ring in an air conditioner provided in this embodiment. In this embodiment, the arc-shaped concave portion 127 on the control box cover 120 can also be positioned directly opposite the water jet ring 212 of the air conditioner 200, allowing water in the water jet ring 212 to flow to the arc-shaped concave portion 127 and circulate back and forth on it, thereby continuously dissipating heat from the control box 100. It should be noted that in this embodiment, either the outdoor fan 211 or the water jet ring 212 can be provided in the air conditioner 200, or both the outdoor fan 211 and the water jet ring 212 can be provided in the air conditioner 200 to achieve efficient heat dissipation of the control box.

[0042] Understandable, such as Figure 3 As shown, compared to the prior art which sets the surface of the control box 100 to a flat surface, the arc concave surface 127 can also increase the surface area of ​​the control box 100, so that the heat on the control box 100 can be better distributed to the arc concave surface 127 with a larger surface area, thereby achieving the purpose of dispersing the heat on the surface of the control box 100 and further alleviating the heat generation problem of the control box 100.

[0043] Meanwhile, since the control box cover 120 is also made of heat-dissipating material, the heat dissipation efficiency of the control box 100 can be further improved when the outdoor fan 211 and the water jet ring 212 dissipate heat from the control box cover 120. It can be understood that the material used for the control box cover 120 in this embodiment can be one of high-efficiency heat-dissipating materials such as aluminum alloy, silver, or copper, and can be adjusted according to actual conditions.

[0044] Optional, such as Figure 2 As shown, in one embodiment, the air conditioner 200 may further include a first mounting bracket 210, a second mounting bracket 220, and at least one heat exchanger 222. The outdoor fan 211 and the water-cooling ring 212 are both mounted on the first mounting bracket 210, and the electrical control box 100 is disposed between the first mounting bracket 210 and the second mounting bracket 220 (i.e., between the outdoor fan 211 and the heat exchanger 222), and is located on top of the air conditioner 200. It is understood that this embodiment does not limit the specific number of heat exchangers 222; the more heat exchangers 222 there are, the better the cooling or heating effect of the air conditioner 200.

[0045] In this embodiment, the control box 100 is located at the top of the air conditioner 200. Compared to the prior art where the control box is located in the middle of the air conditioner, the control box 100 provided in this embodiment can save space inside the air conditioner 200. Furthermore, it can be understood that the negative pressure generated by the rotation of the outdoor fan 211 can drive airflow inside the air conditioner 200. When the control box 100 is located at the top of the air conditioner 200, the negative pressure generated at the edge of the outdoor fan 211 is greater than that generated at the center of the outdoor fan 211. Therefore, the airflow can better contact the control box cover 120 and the concave surface 127, achieving a better heat dissipation effect on the control box 100.

[0046] It should be noted that, in this embodiment, the specific installation method between the electrical control box 100, the first mounting bracket 210 and the second mounting bracket 220 is not limited. For example, it can be one of the fixed connection methods such as snap-fit ​​connection, screw connection or magnetic connection. The specific method can be adjusted according to the actual assembly situation.

[0047] Optional, please refer to Figures 2-4 And see Figure 5 , Figure 5 for Figure 4The diagram shows an enlarged view of part A of the air conditioner. In this embodiment, the air conditioner 200 may also include an indoor fan 221. In this case, the heat exchanger 222 can be installed on the second mounting bracket 220, and the air conditioner 200 achieves cooling or heating effects under the action of the indoor fan 221. However, the heat exchanger 222 will come into contact with room temperature air during operation, thus producing condensate. Therefore, in this embodiment, the air conditioner 200 also has a water collection tray 230 at its bottom, which is positioned directly opposite the heat exchanger 222. This allows the water collection tray 230 to collect the condensate on the heat exchanger 222 and prevents water accumulation at the bottom of the air conditioner 200. Furthermore, the water collection tray 230 can extend to the outdoor fan 221 and be inclined along the direction from the heat exchanger 222 to the outdoor fan 221, so that the water in the water collection tray 230 can flow to the outdoor fan 221. It should be noted that, in this embodiment, the outdoor fan 211 can be an axial fan, and the indoor fan 221 can be a centrifugal fan.

[0048] At the same time, such as Figure 4 and Figure 5 As shown, in this embodiment, the water-spraying ring 212 can be set at the periphery of the outdoor fan 211, and the water-spraying ring 212 is provided with a boss 213. The boss 213 is provided with a recess 214 in the rotation direction of the water-spraying ring 212. When the boss 213 rotates with the water-spraying ring 212, the recess 214 located in the bottom area 216 can carry some condensate. After the boss 213 rotates to the top area 215 (that is, the position where the electrical control box 100 is located), the carried condensate can be released from the recess 214 and thrown onto the arc concave surface 127. The condensate can also flow back and forth on the arc concave surface 127, thereby dissipating heat from the electrical control box 100.

[0049] Furthermore, it can be understood that in this embodiment, since the control box 100 is provided with a top region 215 and the arc-shaped concave surface 127 is positioned directly opposite the recess 214, when the carried condensate water escapes from the recess 214 of the top region 215, the condensate water can be flung onto the arc-shaped concave surface 127. Since the arc-shaped concave surface 127 has a larger surface area than the straight surface, the larger surface area of ​​the arc-shaped concave surface 127 can increase the capacity of the condensate water, thereby allowing more condensate water to accumulate at the arc-shaped concave surface 127. This provides better heat dissipation for the control box 100. Furthermore, due to the concave structure of the arc-shaped concave surface 127, when condensate drips onto it, the water adheres to the surface due to surface tension and flows back and forth for an extended period, resulting in more sustained heat dissipation for the control box 100. This avoids the problem in existing technologies where condensate dripping onto a straight surface accumulates and eventually falls off, thus failing to achieve effective heat dissipation for the control box.

[0050] Meanwhile, it is understood that the specific number of bosses 213 and recesses 214 is not limited in this embodiment. When the number of bosses 213 and recesses 214 is greater, the collection effect of condensate at the water tray 230 is better, so that more condensate is splashed onto the arc concave surface 127, and thus the heat dissipation effect on the electrical control box 100 is better.

[0051] Optionally, in one embodiment, the control box 100 may further include a base 110. For details, please refer to [link to relevant documentation]. Figure 6 , Figure 6 This is an exploded structural diagram of the electrical control box provided in this embodiment. In this embodiment, the electrical control box cover 120 is disposed on the base 110 to form a receiving space 121. The receiving space 121 is used to install components that are prone to heat generation, such as the main control board 130. Since the main control board 130 and other components that are prone to heat generation will dissipate heat in the receiving space 121 when they are working, the heat generated will be transferred to the surface of the electrical control box cover 120 when it is dissipated in the receiving space 121. Therefore, a first air inlet surface 122 is provided on one side of the electrical control box cover 120. When the existing outdoor fan in the air conditioner rotates, the negative pressure when the fan rotates will cause some airflow to flow to the first air inlet surface 122 and contact the first air inlet surface 122, thereby dissipating heat from the surface of the electrical control box cover 120.

[0052] In addition, please combine Figure 7 , Figure 7 for Figure 6The diagram shows an enlarged view of part B of the electrical control box. The electrical control box cover 120 may also include a first heat dissipation surface 123. The first heat dissipation surface 123 extends away from the first air inlet surface 122, allowing the airflow after passing through the first air inlet surface 122 to flow on the first heat dissipation surface 123, thus dissipating heat in the area where the first heat dissipation surface 123 is located on the electrical control box cover 120. Simultaneously, the first heat dissipation surface 123 can also be configured as a continuous curved surface structure. This allows the airflow after passing through the first air inlet surface 122 to enter the continuous curved first heat dissipation surface 123, increasing the heat exchange area of ​​the first heat dissipation surface 123 and enabling more thorough contact between the first heat dissipation surface 123 and the airflow, thereby achieving a better heat dissipation effect. Furthermore, compared to the straight surface structure of the prior art, the continuous curved first heat dissipation surface 123 in this embodiment also increases the surface area of ​​the first heat dissipation surface 123 facing the receiving space 121, thereby increasing the surface area of ​​the receiving space... When the heat inside 121 is transferred to the surface of the control box cover 120, the heat can be more evenly distributed on the first heat dissipation surface 123 with a continuous curved surface, and the overall heat on the first heat dissipation surface 123 can be reduced. This avoids the problem in the prior art where the surface of the control box 100 is set as a straight structure, resulting in the heat in the containment space accumulating on the straight structure with a small surface area, which leads to excessive heat generation on the heat dissipation surface. In addition, the first air inlet surface 122 is also provided with a first groove 1221, so that when the airflow flows on the first air inlet surface 122, the airflow on the first air inlet surface 122 can enter the first groove 1221 and contact more of the surface of the control box cover 120, so that the airflow can more fully exchange heat on the first air inlet surface 122, and the airflow flowing on the first air inlet surface 122 can enter the first groove 1221 and carry away more heat on the first air inlet surface 122, thereby achieving a better heat dissipation effect on the first air inlet surface 122.

[0053] Furthermore, since the main control board 130 typically integrates multiple components, and the heat generated by each component during operation is not uniform, some areas of the control box 100 may experience excessively high temperatures while others remain relatively cool. To address this issue, this application also positions the air outlet of the first groove 1221 towards the first heat dissipation surface 123.

[0054] For details, please continue reading. Figure 7In this embodiment, since the air outlet of the first groove 1221 is arranged facing the first heat dissipation surface 123, the airflow after passing through the first groove 1221 can flow towards the first heat dissipation surface 123 (since the temperature of the area where the first heat dissipation surface 123 is located is different from that of the area where the first air inlet surface 122 is located, the temperature of the airflow in the two areas is also different at this time), and exchange heat with the airflow near the first heat dissipation surface 123, thereby achieving the purpose of combining the temperature of the airflow on the first heat dissipation surface 123 and the airflow on the first air inlet surface 122. After the airflow heat exchange between the two areas is completed, the airflow will continue to dissipate heat to the area where the first heat dissipation surface 123 is located and the area near the first air inlet surface 122. (If the temperature of the airflow on the first heat dissipation surface 123 is high at this time, then after the airflow on the first heat dissipation surface 123 and the airflow on the first air inlet surface 122 exchange heat, the temperature of the airflow on the first heat dissipation surface 123 can be reduced; if the temperature of the airflow flowing through the first groove 1221 is high at this time, then after the airflow on the first heat dissipation surface 123 and the airflow on the first air inlet surface 122 exchange heat, the temperature of the airflow near the first air inlet surface 122 can be reduced.) This reduces the temperature of the control box cover 120, thereby improving heat dissipation in areas with higher temperatures and avoiding the situation in the prior art where the heat generated by each component inside the control box is not uniform, resulting in some areas of the control box cover being too hot while others are too cold. Furthermore, in the prior art, because the airflow used to dissipate heat from the control box cannot exchange heat, the airflow flowing over the control box may be too hot in some areas and too cold in others, leading to uneven heat dissipation in the control box.

[0055] Optional, please continue reading Figure 7 In one embodiment, the control box cover 120 may further include a second heat dissipation surface 124. The second heat dissipation surface 124 extends away from the first air inlet surface 122, and the first air inlet surface 122, the first heat dissipation surface 123, and the second heat dissipation surface 124 are arranged adjacent to each other. This allows the airflow after passing through the first air inlet surface 122 to directly enter the adjacent first heat dissipation surface 123 and second heat dissipation surface 124, and dissipate heat in the area where the first heat dissipation surface 123 is located and the area where the second heat dissipation surface 124 is located. This accelerates the heat dissipation efficiency of the airflow on the control box 100 by shortening the distance between the first air inlet surface 122, the first heat dissipation surface 123, and the second heat dissipation surface 124.

[0056] It is understandable that, such as Figure 7As shown, in this embodiment, the first heat dissipation surface 123 and the second heat dissipation surface 124 can be recessed in the first air inlet surface 122 in a direction away from the first air inlet surface 122, which is more conducive to the flow of air and allows the airflow after passing through the first air inlet surface 122 to flow directly to the first heat dissipation surface 123 and the second heat dissipation surface 124 in the direction of airflow.

[0057] Meanwhile, the first groove 1221 can also be disposed on the side of the first air inlet surface 122 near the second air inlet surface 150, and the first groove 1221 can include a first end 1222 disposed near the second heat dissipation surface 124 and a second end 1223 disposed away from the second heat dissipation surface 124. The first end 1222 is disposed toward the first heat dissipation surface 123, so that the airflow after passing through the first groove 1221 can flow toward the first heat dissipation surface 123 and exchange heat with the airflow near the first heat dissipation surface 123, thereby achieving the purpose of combining the temperature of the airflow on the first heat dissipation surface 123 and the airflow on the first air inlet surface 122.

[0058] Optional, please refer to Figure 7 And see Figure 8 and Figure 9 , Figure 8 This is a side view of the electrical control box provided in an embodiment of this application. Figure 9 for Figure 8 The diagram shows an enlarged view of part C of the electrical control box. In one embodiment, the first groove 1221 can be S-shaped. Compared with the conventional straight groove in the prior art, the S-shaped first groove 1221 can increase the airflow into the first groove 1221 by increasing the internal volume of the first groove 1221. This allows the airflow to contact more of the first air inlet surface 122, thereby further improving the heat dissipation effect of the airflow on the first air inlet surface 122.

[0059] In addition, such as Figure 7 and Figure 9As shown, the included angle between the first end portion 1222 and the first heat dissipation surface 123 can be 45° to 60°. Specifically, since the shape of the first groove 1221 is S-shaped, the first end portion 1222 of the first groove 1221 near the second heat dissipation surface 124 can form a certain tilt angle. Simultaneously, since the first heat dissipation surface 123 is a continuous curved surface structure, it can be understood that the first heat dissipation surface 123 can include a flat plane and a circular arc concave portion 127 protruding from or recessed into the plane. The included angle between the first end portion 1222 and the plane can be 60°, and the included angle between the first end portion 1222 and the circular arc concave portion 127 can be... When the angle between the first end 1222 and the first heat dissipation surface 123 is between 45° and 60°, the airflow from the first end 1222 can flow directly to the first heat dissipation surface 123 and flow on the first heat dissipation surface 123. This not only improves the convection efficiency between the first groove 1221 and the first heat dissipation surface 123, but also further avoids the problem that the airflow from the first end 1222 does not directly enter the first heat dissipation surface 123, but flows to the outside and mixes with the outside air, thus causing airflow loss.

[0060] Optional, such as Figure 7 As shown, in one embodiment, both the first heat dissipation surface 123 and the second heat dissipation surface 124 are provided with a second groove, and the second groove extends away from the first air inlet surface 122. This allows the airflow flowing on the first heat dissipation surface 123 and the second heat dissipation surface 124 to enter the second groove, and allows the airflow to contact more of the first heat dissipation surface 123 and the second heat dissipation surface 124, so as to achieve more complete heat exchange between the first heat dissipation surface 123 and the second heat dissipation surface 124. Furthermore, the airflow flowing over the first heat dissipation surface 123 and the second heat dissipation surface 124 can enter the second groove and carry away more heat from the first heat dissipation surface 123 and the second heat dissipation surface 124, thereby achieving a better heat dissipation effect on the first heat dissipation surface 123 and the second heat dissipation surface 124. It can be understood that the second groove in this embodiment may include a second groove 1231A provided on the first heat dissipation surface 123 and a second groove 1231B provided on the second heat dissipation surface 124.

[0061] Please continue to refer to Figure 7In this embodiment, the second groove 1231B located on the second heat dissipation surface 124 is connected to the first groove 1221. Since the first air inlet surface 122 is adjacent to the second heat dissipation surface 124, when the airflow flows out from the first end 1222, part of the airflow flowing out from the first end 1222 can enter the first heat dissipation surface 123 and exchange heat with the airflow on the first heat dissipation surface 123. The other part of the airflow flowing out from the first end 1222 can flow to the second groove 1231B of the second heat dissipation surface 124, thereby exchanging heat with the airflow on the second heat dissipation surface 124. This achieves the purpose of combining the temperatures of the area described by the first groove 1221, the area where the first heat dissipation surface 123 is located, and the area where the second heat dissipation surface 124 is located, and improves the heat dissipation effect of the high-temperature area on the electrical control box 100.

[0062] Optionally, in one embodiment, the control box cover 120 may further include a third heat dissipation surface 125 and a fourth heat dissipation surface 126 that are adjacent to each other. Please refer to [link to relevant documentation]. Figure 7 and combined Figures 10-11 , Figure 10 This is a schematic diagram of the overall structure of the electrical control box provided in an embodiment of this application. Figure 11 for Figure 10 The diagram shows an enlarged view of part D of the electrical control box.

[0063] Specifically, in this embodiment, the third heat dissipation surface 125 and the fourth heat dissipation surface 126 are disposed on the side of the first heat dissipation surface 123 away from the first air inlet surface 122, and the third heat dissipation surface 125 is adjacent to the first heat dissipation surface 123 and the second heat dissipation surface 124, so that the airflow after passing through the first heat dissipation surface 123 and the airflow after passing through the second heat dissipation surface 124 can flow directly to the third heat dissipation surface 125 and flow on the third heat dissipation surface 125 to dissipate heat in the area where the third heat dissipation surface 125 is located.

[0064] At the same time, such as Figure 11 As shown, the third heat dissipation surface 125 protrudes in a direction away from the first heat dissipation surface 123, while the fourth heat dissipation surface 126 is adjacent to the side of the third heat dissipation surface 125 away from the first heat dissipation surface 123. This allows the airflow on the third heat dissipation surface 125 to flow along the protruding direction of the third heat dissipation surface 125 and eventually reach the fourth heat dissipation surface 126 when airflow flows from the third heat dissipation surface 125 to the fourth heat dissipation surface 126. It can be understood that when the airflow on the third heat dissipation surface 125 reaches the fourth heat dissipation surface 126, the airflow can also flow on the fourth heat dissipation surface 126 due to the negative pressure generated by the rotation of the existing outdoor fan 211, thereby dissipating heat from the area where the fourth heat dissipation surface 126 is located, further improving the heat dissipation effect of the electrical control box 100.

[0065] It is understood that in this embodiment, in addition to the airflow flowing through the third heat dissipation surface 125 dissipating heat on the fourth heat dissipation surface 126, the negative pressure generated by the rotation of the outdoor fan 211 can also allow the airflow near the electrical control box 100 to flow onto the fourth heat dissipation surface 126 to dissipate heat on the fourth heat dissipation surface 126.

[0066] Additionally, please see Figure 7 and Figure 11 In this embodiment, the third heat dissipation surface 125 is further provided with a third groove 1251, and the fourth heat dissipation surface 126 is provided with a fourth groove 1261 on the side close to the third heat dissipation surface 125. This allows the airflow flowing on the third heat dissipation surface 125 to enter the third groove 1251, and the airflow flowing on the fourth heat dissipation surface 126 to enter the fourth groove 1261. By increasing the heat exchange area between the airflow and the third heat dissipation surface 125 and the fourth heat dissipation surface 126, a better heat dissipation effect of the airflow on the third heat dissipation surface 125 and the fourth heat dissipation surface 126 is achieved.

[0067] At the same time, such as Figure 7 and Figure 11 As shown, one end of the third groove 1251 can connect to the fourth groove 1261, and the other end can extend towards the first heat dissipation surface 123. This not only increases the internal volume of the third groove 1251, thereby increasing the airflow into it and further improving the heat dissipation effect on the first air inlet surface 122 when the airflow flows on the third heat dissipation surface 125, but also, when the third groove 1251 connects to the fourth groove 1261, since the third heat dissipation surface 125 and the fourth heat dissipation surface 126 are adjacent, when the airflow flows out of the third groove 1251, part of the airflow will continue to flow along the convex direction of the third heat dissipation surface 125, thus dissipating heat to other areas of the electrical control box 100, while the other part... The airflow can then flow directly to the fourth groove 1261 and eventually to the fourth heat dissipation surface 126, where it exchanges heat with the airflow on the fourth heat dissipation surface 126. This achieves the purpose of combining the temperatures of the airflow on the third heat dissipation surface 125 and the airflow on the fourth heat dissipation surface 126. (If the temperature of the airflow on the third heat dissipation surface 125 is high at this time, the temperature of the airflow on the third heat dissipation surface 125 can be reduced after heat exchange with the airflow on the fourth heat dissipation surface 126; if the temperature of the airflow on the fourth heat dissipation surface 126 is high at this time, the temperature of the airflow on the fourth heat dissipation surface 126 can be reduced after heat exchange with the airflow on the third heat dissipation surface 125.) This improves the heat dissipation effect on the high-temperature areas of the electrical control box 100.

[0068] Optional, such as Figure 10and Figure 11 As shown, in one embodiment, the concave portion 127 of the control box cover 120 can protrude beyond the fourth heat dissipation surface 126, allowing the airflow after passing through the fourth heat dissipation surface 126 to flow along the protruding direction of the concave portion 127, thereby achieving heat dissipation for the area where the concave portion 127 is located. It can be understood that in this embodiment, in addition to the airflow after passing through the fourth heat dissipation surface 126 dissipating heat from the concave portion 127, the negative pressure generated by the rotation of the outdoor fan 211 can also allow the airflow near the control box 100 to flow onto the concave portion 127, thereby dissipating heat from the concave portion 127.

[0069] Please continue to refer to Figure 10 and Figure 11 The concave portion 127 is recessed in a direction away from the fourth heat dissipation surface 126 to form an arc surface 1271, so that the airflow flowing on the concave portion 127 can flow along the arc surface 1271. Since the arc surface 1271 has a larger surface area than the existing straight surface, the arc surface 1271 with a larger surface area can not only better disperse the heat in the accommodating space 121, so that the overall temperature on the arc surface 1271 is lower than the overall temperature on the straight surface, thereby reducing the heat generation of the electrical control box 100 in the area of ​​the arc surface 1271, but also, when the airflow flows on the arc surface 1271, since the surface area of ​​the arc surface 1271 is larger, the airflow flowing on the arc surface 1271 can make more full contact with the arc surface 1271, thereby carrying away more heat from the concave portion 127, so as to achieve a better heat dissipation effect on the concave portion 127.

[0070] In addition, such as Figure 10 and Figure 11 As shown, a fifth groove 1272 can also be provided on the arc surface 1271. The fifth groove 1272 is arranged along the length direction of the arc surface 1271, so that the airflow flowing on the arc concave surface 127 can enter the fifth groove 1272. By increasing the heat exchange area between the airflow and the arc concave surface 127, the airflow can achieve a better heat dissipation effect on the arc concave surface 127. At the same time, the fifth groove 1272 is also connected to the second groove 1231B located on the second heat dissipation surface 124, so that the airflow in the fifth groove 1272 can exchange heat with the airflow on the second heat dissipation surface 124, thereby improving the heat dissipation effect on the high-temperature areas on the electrical control box 100.

[0071] It is understandable that when the condensate carried out is removed from the recess 214 of the top region 215, the condensate will not only drip onto the arc surface 1271, but also drip into the fifth groove 1272, thereby achieving the heat dissipation effect on the space within the fifth groove 1272; at the same time, some of the condensate can also drip onto the second heat dissipation surface 124 and the second groove 1231B located on the second heat dissipation surface 124, thereby achieving the heat dissipation effect of the condensate on the second heat dissipation surface 124.

[0072] Optional, please refer to Figure 6 and Figure 10 The control box cover 120 may also be provided with a mounting port 128, which is located on the side of the control box 100 away from the first air intake surface 122. The mounting port 128 is also connected to the receiving space 121, thereby forming a second air intake surface 150. It can be understood that the negative pressure generated when the outdoor fan 211 rotates can allow airflow near the control box 100 to enter from both sides of the control box 100 (i.e., the first air intake surface 122 and the second air intake surface 150), and allow the flowing airflow to dissipate heat from the area near the first air intake surface 122 and the area near the second air intake surface 150.

[0073] At the same time, such as Figure 6 As shown, the electrical control box 100 may also include multiple spaced fins 140. The multiple fins 140 can be installed on the main control board 130 to achieve heat dissipation for the main control board 130. After the base 110, the cover 120 and the main control board 130 of the electrical control box 100 are assembled, the multiple spaced fins 140 can be set at the mounting port 128. At this time, a gap can be formed between every two fins 140. When the second air inlet 150 is inlet, the air can enter the accommodating space 121 through the gap between the mounting port 128 and the fins 140, thereby dissipating heat from the main control board 130 in the accommodating space 121. In this embodiment, placing the fins 140 at the mounting port 128 can also serve as a dustproof and waterproof measure, making it difficult for external dust and water mist to enter the accommodating space 121 from the mounting port 128. This prevents dust and water mist from contacting the main control board 130, which could lead to a short circuit or damage to the main control board 130.

[0074] In addition, such as Figure 6 As shown, in one embodiment, the end of the electrical control box cover 120 away from the fourth heat dissipation surface 126 is also provided with a chamfer structure 1224. The chamfer structure 1224 can compress the volume of the accommodating space 121, so that the airflow entering the accommodating space 121 from the second air inlet surface 150 can flow quickly in the accommodating space 121, thereby accelerating the heat exchange efficiency between the airflow and the main control board 130, and further improving the heat dissipation effect of the airflow on the main control board 130.

[0075] This application also provides an air conditioner 200, such as... Figure 1 As shown, the air conditioner 200 includes a housing 240 and the aforementioned electrical control box 100, wherein the electrical control box 100 is disposed inside the housing 240 to achieve heat dissipation for the electrical control box inside the air conditioner 200.
