[0074] In some embodiments of the present application, as shown in Figures 8-15 As shown, the electric control box 3 includes a top cover plate 301 and a bottom cover plate 302 arranged in the up-down direction, a first surrounding plate 303, a second surrounding plate 304 and a third surrounding plate 305 are connected between the top cover plate 301 and the bottom cover plate 302, and the first surrounding plate 303, the second surrounding plate 304 and the third surrounding plate 305 are connected to the periphery of the top cover plate 301 and the bottom cover plate 302 and define a first cavity, the electric control 4 is arranged in the first cavity, the first air inlet 315 and the first branch air inlet 3211 are formed on the second surrounding plate 304, and the second branch air inlet 3221 is formed on the bottom cover plate 302. That is, the top cover plate 301 is located at the top, the top cover plate 301 is arranged in the up-down direction with the bottom cover plate 302, the bottom cover plate 302 is located at the bottom, the bottom cover plate 302 is arranged opposite to the top cover plate 301, the first surrounding plate 303, the second surrounding plate 304 and the third surrounding plate 305 are connected between the top cover plate 301 and the bottom cover plate 302, the top cover plate 301, the bottom cover plate 302, the first surrounding plate 303, the second surrounding plate 304 and the third surrounding plate 305 define a first cavity, the first air inlet 315 is formed on the second surrounding plate 304 for introducing air from the compressor compartment 13 into the first air channel 31, the first branch air inlet 3211 is formed on the second surrounding plate 304 for introducing air into the first branch 321 of the second air channel 32, and the second branch air inlet 3221 is formed on the bottom cover plate 302 and directly communicates with the compressor compartment 13 for introducing air into the second branch 322 of the second air channel 32.

[0075] It can be understood that by arranging air inlets at different positions, multi-path air intake is achieved, the total air flow is increased, and the heat dissipation efficiency is improved, and through different air inlet positions, a more uniform temperature distribution can be formed in the electric control box 3, reducing the risk of local overheating.

[0076] In some embodiments of this utility model, a first partition 306 is provided inside the first cavity. The first partition 306 extends in the left-right direction and is located between the first air duct 31 and the second air duct 32. For example... Figure 10 As shown, the first partition 306 extends in the left-right direction and is located between the first air duct 31 and the second air duct 32, serving as a separator. The first partition 306 completely separates the first air duct 31 and the second air duct 32, preventing airflow crossover and ensuring that the airflow in each air duct can flow independently, thereby improving heat dissipation efficiency. Furthermore, by isolating the two air ducts, the temperature distribution in different areas can be better controlled, reducing the impact of heat transfer on the cooling effect. The first partition 306 also enhances the overall structural strength of the electrical control box 3, making it more robust and durable. It can be understood that by setting the first partition 306 in the first cavity, more efficient airflow management and heat dissipation control are achieved, which not only improves the system's heat dissipation efficiency but also enhances the overall reliability and service life. Through reasonable airflow management and the layout of the radiator 5, the working environment of the electrical control component 2 can be further optimized, ensuring its long-term stable operation.

[0077] In some embodiments of this utility model, the electrical control box 3 is provided with a second partition 307. The electrical control box 3 has a second cavity with an open bottom, located on the side of the second partition 307 away from the first cavity. Ventilation openings 33 communicating with the second cavity are formed on both the front and rear sides of the electrical control box 3. The radiator 5 is disposed in the second cavity, and at least a part of the second cavity is located in the impeller compartment 12. The second exhaust outlet 3121 and the second exhaust outlet 324 are both formed in the second cavity. That is, the second partition 307 divides the electrical control box 3 into two main areas (the first cavity and the second cavity). The first cavity contains the electrical control unit 4, which is cooled by introducing air through the first air inlet 315, the first branch air inlet 3211, and the second branch air inlet 3221. The bottom of the second cavity is open, located on the side of the second partition 307 away from the first cavity, and is mainly used to house the radiator 5 and communicates with the outside through the ventilation openings 33 on the front and rear sides.

[0078] Further, the front and back sides of the electric control box 3 are formed with air vents 33 communicating with the second cavity, allowing air to flow freely, and the heat sink 5 is arranged in the second cavity, and at least part of the second cavity is located in the fan wheel compartment 12, which helps to enhance the heat dissipation effect by using the fan in the fan wheel compartment 12. By arranging multiple air inlets and air outlets, multi-path heat dissipation can be achieved, the total air flow is increased, and the heat dissipation efficiency is improved; the independent design of the first cavity and the second cavity can better control the temperature distribution in different areas and reduce the influence of heat transfer on the cooling effect; the first partition plate 306 and the second partition plate 307 enhance the overall structural strength of the electric control box 3, making it more robust and durable; the second cavity is located in the fan wheel compartment 12, which can use the fan in the fan wheel compartment 12 to accelerate air flow and improve the heat dissipation efficiency of the heat sink 5, and different electric controls 4 and heat sinks 5 can be arranged in the first cavity and the second cavity respectively to achieve the best heat dissipation effect.

[0079] In some embodiments of the present application, as shown in Figure 10 The second partition plate 307 includes a first plate portion 3071 and a second plate portion 3072, the first plate portion 3071 extends in the front-rear direction, and the second plate portion 3072 extends in the left-right direction and is located between the third branch 311 and the fourth branch 312, one end of the first plate portion 3071 is connected to one end of the second plate portion 3072, and the second plate portion 3072, the top cover plate 301, the first surrounding plate 303 and the bottom cover plate 302 together define the third branch 311. Referring to the drawings, the first plate portion 3071 extends in the front-rear direction, the second plate portion 3072 extends in the left-right direction and is located between the third branch 311 and the fourth branch 312, one end of the first plate portion 3071 is connected to one end of the second plate portion 3072, and they together define different air duct regions. Specifically, the rear end of the first plate portion 3071 is connected to the right end of the second plate portion 3072, the first plate portion 3071 extends in the front-rear direction to completely separate the second cavity from the first cavity, preventing air flow from crossing; the second plate portion 3072 extends in the left-right direction and is located between the third branch 311 and the fourth branch 312, ensuring that the air flow between the third branch 311 and the fourth branch 312 does not interfere with each other, and the third branch 311 is an independent air duct defined by the second plate portion 3072, the top cover plate 301, the first surrounding plate 303 and the bottom cover plate 302, used for introducing air and heat dissipation treatment.

[0080] In this way, by isolating different air ducts, the temperature distribution in different areas can be better controlled, the influence of heat transfer on the cooling effect can be reduced, the first plate portion 3071 and the second plate portion 3072 enhance the overall structural strength of the electric control box 3, making it more robust and durable, and different electric controls 4 and heat sinks 5 can be arranged in different air ducts to achieve the best heat dissipation effect.

[0081] In some embodiments of the present application, as shown in Figure 8 ,Figure 13 and Figure 14 As shown, the first partition 306, the top cover 301, the first enclosure 303, and the bottom cover 302 together define the air inlet 313 of the first air duct 31; the third enclosure 305, the bottom cover 302, the top cover 301, and the first partition 306 together define the first branch 321 of the second air duct 32; the first partition 306, the bottom cover 302, the top cover 301, and the first plate portion 3071 of the second partition 307 together define the second branch 322 of the second air duct 32. In other words, the air inlet 313 of the first air duct 31 is jointly defined by the first partition 306, the top cover plate 301, the first enclosure plate 303, and the bottom cover plate 302, and is used to introduce air into the first air duct 31 and cool it through the electrical control 4; the first branch 321 of the second air duct 32 is jointly defined by the third enclosure plate 305, the bottom cover plate 302, the top cover plate 301, and the first partition 306, and the first branch 321 is part of the second air duct 32, and is used to introduce air and perform heat dissipation; the second branch 322 of the second air duct 32 is jointly defined by the first partition 306, the bottom cover plate 302, the top cover plate 301, and the first plate portion 3071 of the second partition 307, and the second branch 322 is another part of the second air duct 32, and is used to introduce air and perform heat dissipation.

[0082] Therefore, multiple independent air ducts enable multi-path heat dissipation, increasing the total airflow and improving heat dissipation efficiency. The isolation design between each air duct allows for better control of temperature distribution in different areas, reducing the impact of heat transfer on the cooling effect. Multiple partitions and enclosures enhance the overall structural strength of the electrical control box 3, making it more robust and durable. Different electrical control units 4 and radiators 5 can be arranged in different air ducts to achieve the best heat dissipation effect, which not only improves the system's heat dissipation efficiency but also enhances the overall reliability and service life.

[0083] In some embodiments of this utility model, such as Figure 11 As shown, the control box 3 also has a third partition 308, which extends horizontally and is located below the inductor of the control box 4. The distance between the third partition 308 and the top cover 301 is less than the distance between the bottom cover 302 and the top cover 301. It is understood that the third partition 308 isolates the inductor from other parts of the control box 3, helping to reduce the impact of heat generated by the inductor on other components. By setting the third partition 308, air can be guided to flow more effectively through the inductor, improving its heat dissipation efficiency. The third partition 308 also enhances the overall structural strength of the control box 3, making it more robust and durable.

[0084] Further, the distance between the third partition plate 308 and the inductive element is 5mm-10mm. It can be understood that the distance of 5mm to 10mm can ensure that there is enough space for air circulation between the third partition plate 308 and the inductive element, while maintaining good heat conduction. In this way, the temperature of the inductive element can be effectively reduced. If the distance is too small (less than 5mm), it may cause poor air flow and affect the heat dissipation effect; if the distance is too large (greater than 10mm), it occupies the space in the box 1.

[0085] For example, the distance between the third partition plate 308 and the inductive element can be 5mm, 5.1mm, 5.2mm, 5.3mm, 5.4mm, 5.5mm, 5.6mm, 5.7mm, 5.8mm, 5.9mm, 6mm, 6.1mm, 6.2mm, 6.3mm, 6.4mm, 6.5mm, 6.6mm, 6.7mm, 6.8mm, 6.9mm, 7mm, 7.1mm, 7.2mm, 7.3mm, 7.4mm, 7.5mm, 7.6mm, 7.7mm, 7.8mm, 7.9mm, 8mm, 8.1mm, 8.2mm, 8.3mm, 8.4mm, 8.5mm, 8.6mm, 8.7mm, 8.8mm, 8.9mm, 9mm, 9.1mm, 9.2mm, 9.3mm, 9.4mm, 9.5mm, 9.6mm, 9.7mm, 9.8mm, 9.9mm, 10mm, etc.

That is, the first branch air inlet 3211 and the position of the first air inlet 315 are both provided with a grille part 309, the grille part 309 includes a plurality of upward and downward extending air deflectors 3091. These air deflectors 3091 extend obliquely away from the wind wheel bin 12 in the front-to-back direction, and each air deflector 3091 is connected with the second surrounding plate 304, which can effectively guide the air flow, improve the heat dissipation efficiency, and reduce the dust and impurities entering the electric control box 3.

[0087] It can be understood that the air deflectors 3091 extend up and down to form a grid structure, and the air deflectors 3091 extend obliquely away from the wind wheel bin 12 in the front-to-back direction, which helps to guide the airflow into the inside of the electric control box 3. Each air deflector 3091 is connected with the second surrounding plate 304 to ensure the stability and integrity of the structure. Specifically, the inclined design of the air deflector 3091 can effectively guide the air from the air inlet into the inside of the electric control box 3, making the airflow smoother and reducing turbulence and resistance, which helps to improve the air flow and enhance the heat dissipation effect; the grid structure can block larger dust particles and other impurities from entering the inside of the electric control box 3, protecting the electric control 4 from pollution, and by reasonably designing the spacing of the air deflectors 3091, the dustproof effect can be further optimized without affecting the circulation of the airflow; the air deflectors 3091 are connected with the second surrounding plate 304, which enhances the overall structural strength of the grid part 309, making it more durable and preventing the air deflectors 3091 from deforming or being damaged during use.

It can be understood that by providing a plurality of through holes 30721 on the first plate part 3071 of the second partition plate 307, effective airflow exchange and pressure balance can be achieved between the first cavity and the second cavity, thereby improving the heat dissipation efficiency of the entire electric control box 3. As shown, the plurality of through holes 30721 make the first air duct 31 communicate, and the plurality of through holes 30721 also make the second air duct 32 communicate, which not only optimizes airflow management but also enhances the reliability and service life of the electric control assembly 2. Through reasonable layout of the through holes 30721, material selection, and manufacturing and assembly process, the effectiveness and safety of the electric control assembly 2 can be ensured.

It can be understood that the electric control assembly 2 is inverted, and the electric control board 6 is located at the top as the basis for mounting the electric control 4 and the heat sink 5. The electric control 4 is arranged below the electric control board 6 and is responsible for controlling and processing electrical signals. The heat sink 5 is also arranged below the electric control board 6 and is used to dissipate the heat generated by the electric control 4. The electric control 4 and the heat sink 5 are arranged in the left-right direction to ensure good heat dissipation effect.

[0090] Specifically, the spacing arrangement between the electrical control 4 and the heat sink 5 helps to reduce direct heat transfer, avoid overheating of the electrical control 4, form a relatively independent heat zone, enable heat to be dissipated more effectively through the heat sink 5, the spacing arrangement enables air to flow more evenly through the electrical control 4 and the heat sink 5, improving overall heat dissipation efficiency, the spacing arrangement of the electrical control 4 and the heat sink 5 facilitates maintenance and repair, which can be operated without disturbing other components, and if a component needs to be replaced or repaired, it can be more easily disassembled and installed.

Different air inlets can cool different components, such as the electrical control assembly 2 and the compressor.
