Description

TECHNICAL FIELD

[0001] The application relates to the field of air conditioner fan motor heat dissipation, in particular to an air conditioner fan motor heat dissipation system. BACKGROUND

[0002] The core function of an air conditioner is to create a comfortable, healthy or specific indoor environment for human beings by adjusting the temperature, humidity, cleanliness and flow speed of air. According to the structure, an air conditioner system can be divided into an outdoor unit and an indoor unit. The outdoor unit is usually installed on the outer wall of a building, a balcony or a roof, etc. for compressing refrigerant and discharging heat. The indoor unit is installed on the indoor wall, ceiling, floor or window frame, etc. for air supply and heat exchange to adjust the room temperature, humidity and air cleanliness.

[0003] The fan rotates under the control of the motor inside the outdoor unit to dissipate the heat absorbed by the refrigerant, thereby discharging the heat inside the outdoor unit. However, problems such as excessive dust accumulation, high or low voltage, high ambient temperature and excessive load of the fan motor can cause overheating of the fan motor. High temperature can cause the wires of the motor winding to overheat, the insulation layer to melt, the inter-turn short circuit of the winding or the short circuit between the winding and the shell, and finally burn the motor. The motor failure can cause poor heat dissipation of the outdoor unit, increased condensation pressure of the refrigerant, reduced refrigeration cycle efficiency and reduced refrigeration capacity.

[0004] Some outdoor units are installed in harsh environments such as high temperature, closed or dust-filled environments, for example, in a "prison-like" grid with poor ventilation, a west-facing wall exposed to the sun for a long time, or a place with a lot of dust and oil such as a textile factory or a restaurant kitchen. The air conditioner outdoor unit is like being placed in a natural "oven". The fan motor inside not only continuously generates heat itself, but also is forced to suck in high-temperature and dirty air, causing the traditional heat dissipation method to gradually fail, and the motor is easily burned due to local overheating.

[0005] The existing air conditioner fan motor heat dissipation is to spray water on the surface of the outdoor unit to cool the water and reduce the temperature around the outdoor unit, thereby indirectly dissipating heat from the motor inside the outdoor unit. However, the air conditioner fan motor is prone to local overheating, which is usually caused by a combination of factors such as lack of oil or wear of the bearing leading to increased friction, local short circuit of the winding or abnormal concentration of current due to insulation aging, heat accumulation caused by dust blocking the heat dissipation duct, and long-term overloading or unstable voltage. These local defects break the balance between heat generation and dissipation, eventually forming a significant temperature rise in a specific area. Only the same area of the air conditioner fan motor is cooled, which is difficult to effectively cool other areas with high temperature rise, thereby reducing the heat dissipation efficiency and increasing the heat dissipation time of the motor fan.

[0006] Therefore, it is necessary to design an air conditioner fan motor heat dissipation system that can accurately dissipate heat according to the heating area of the motor in harsh environments. SUMMARY

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.

[0022] Please refer to Figures 1-8The present invention provides a technical solution: an air conditioner fan motor heat dissipation system, including an outer casing 1, a solar panel 2 for collecting solar energy on the upper side of the outer casing 1, an air outlet 3 on one side of the outer casing 1, a baffle 4 inside the outer casing 1, a compressor 5 on one side of the baffle 4, a control box 6 on the other side of the baffle 4, a controller and a battery inside the control box 6, heat dissipation fins 7 fixedly connected inside the outer casing 1, a plurality of condenser pipes 8 inside the heat dissipation fins 7, and a heat dissipation mechanism 9 on one side of the control box 6 for detecting the heat-generating area of ​​the air conditioner fan motor and dissipating heat from the local heat-generating area.

[0023] The following is a supplementary explanation based on the above structure: the solar panel 2 converts the solar energy absorbed during the day into electrical energy and delivers it to the storage battery. The storage battery is used to store electrical energy and provide power to the entire detection component 97 and the air-cooled component 98, thereby achieving the effect of saving energy.

[0024] Please see Figures 3-5 The heat dissipation mechanism 9 includes a support frame 91 fixedly connected to the inside of the outer casing 1. A fan motor 92 is provided on the upper side of the support frame 91. A rotating shaft 95 is fixedly connected to the output end of the fan motor 92. A first fan 93 is fixedly connected to one end of the rotating shaft 95. A positioning circular plate 94 is fixedly connected to one side of the fan motor 92. Two U-shaped positioning plates 96 are fixedly connected to one side of the positioning circular plate 94. The other end of each U-shaped positioning plate 96 is fixedly connected to the support frame 91. Two guide sliders 99 are provided on the lower side of the air-cooling component 98 and the guide sliders 99 are fixedly connected to the support frame 91. A detection component 97 for measuring the temperature of different areas of the air-conditioning fan motor is provided on the upper side of the fan motor. An air-cooling component 98 for dissipating heat from localized hot areas of the air-conditioning fan motor is provided on the upper side of the detection component 97.

[0025] The following is a supplementary explanation based on the above structure: the rotation of the output end of the fan motor 92 is used to control the rotation of the first fan 93, thereby dissipating the heat inside the outer casing 1. A circular groove is formed between the positioning circular plate 94 and the support frame 91. The circular groove is used to pass the connected wires and prevent the wires from interfering. The U-shaped positioning plate 96 is used to fix the positioning circular plate 94, thereby indirectly fixing the fan motor 92.

[0026] Please see Figures 5-7 The detection component 97 includes a guide ring 978 fixedly connected to the outside of the rotating shaft 95. The outer side of the guide ring 978 is symmetrically provided with two guide grooves 979 about the rotating shaft 95 as the axis, and the two ends of the two guide grooves 979 are connected to each other.

[0027] The following is a supplementary explanation based on the above structure: When the output end of the fan motor 92 rotates, it drives the rotating shaft 95 to rotate, thereby indirectly driving the guide ring 978 to rotate, causing the two guide sliding grooves 979 to rotate, which in turn drives the sliding column 974 to move. When the guide ring 978 rotates 180 degrees clockwise, the sliding column 974 moves linearly and approaches the fan motor 92. When the guide ring 978 rotates 180 degrees clockwise again, the sliding column 974 moves linearly and moves away from the fan motor 92, thereby causing the sliding column 974 to slide back and forth in a linear motion.

[0028] Please see Figure 8 a) is the front-end heating area of ​​fan motor 92. Front-end heating of fan motor 92 is typically caused by a partial short circuit in the motor windings at the front end, leading to current concentration in the short-circuit area and generating additional Joule heat. This may be due to wear, aging, or manufacturing defects in the winding insulation layer at the front end. b) is the middle-end heating area of ​​fan motor 92. Middle-end heating of fan motor 92 is typically caused by the current increasing when the load on the middle windings exceeds its rated range. According to Joule's law, heat generation is proportional to the square of the current, so the windings will heat up due to excessive current. This is caused by excessive cooling or heating demand from the air conditioning system, or excessive load on the fan driven by the motor. c) is the rear-end heating area of ​​fan motor 92. Rear-end heating of fan motor 92 is typically caused by poor lubrication or wear of the rear bearing, leading to poor operation at the rear end of the motor and frictional heat generation, especially at high speeds. A faulty rear bearing will generate even more heat. Initially, the position of the slide block 974 is as follows... Figure 5 As shown, when the output end of the fan motor 92 rotates 60 degrees clockwise, the infrared probe 975 slides to the front heating area of ​​the fan motor 92. When the output end of the fan motor 92 rotates 60 degrees clockwise again, the infrared probe 975 slides to the middle heating area of ​​the fan motor 92. When the output end of the fan motor 92 rotates 60 degrees clockwise again, the infrared probe 975 slides to the rear heating area of ​​the fan motor 92. This cycle repeats, causing the infrared probe 975 to move back and forth between the front, middle, and rear areas of the fan motor 92.

[0029] The guide slide groove 979 is internally slidably connected to a slide column 974. The contact surface between the slide column 974 and the guide slide groove 979 is spherical. A guide slide plate 971 is fixedly connected to one side of the positioning circular plate 94. The guide slide plate 971 is internally provided with a guide slide groove 976.

[0030] The following is a supplementary explanation based on the above structure: while sliding linearly, the slide bar 974 drives the infrared probe 975 and the laser receiver 973 to move, so that the infrared probe 975 slides back and forth above the fan motor 92, and the laser receiver 973 moves closer to or away from the laser emitter 972.

[0031] The guide plate 971 has a first slider 977 slidably connected inside. An infrared probe 975 is fixedly connected to one side of the first slider 977 and is slidably connected to the guide groove 976.

[0032] The following is a supplementary explanation based on the above structure: the infrared probe 975 is used to detect the temperature of different heat-generating areas of the fan motor 92. The infrared probe 975 focuses the infrared radiation emitted by the object onto the thermopile chip through a silicon-germanium lens. The chip converts the radiation energy into a microvolt voltage, which is then amplified, compensated for by ambient temperature, and linearized to output an electrical signal that is proportional to the surface temperature of the object, thus realizing non-contact temperature measurement. When the surface temperature of the fan motor 92 reaches 100 degrees Celsius, it needs to be cooled down immediately.

[0033] The detection end of the infrared probe 975 is not in contact with the surface of the fan motor 92. The lower side of the first slider 977 is fixedly connected to the slide column 974, and the outer side of the slide column 974 is fixedly connected to the laser receiver 973.

[0034] A laser emitter 972 is fixedly connected to one side of the fan motor 92, and the output end of the laser emitter 972 is aligned with the input end of the detection component 97.

[0035] The following is a supplementary explanation based on the above structure: The laser emitter 972 emits laser pulses to the laser receiver 973. By accurately measuring the time it takes for the laser pulses to travel between the emitter and the receiver 973, and using the known speed of light, the distance between them is calculated. Assuming the laser emitter 972 is 21cm away from the receiver 973, the infrared probe 975 is located in the front end region of the fan motor 92. When the distance between the laser emitter 972 and the receiver 973 is 14cm, the infrared probe 975 is located in the middle region of the fan motor 92. When the distance between the laser emitter 972 and the receiver 973 is 7cm, the infrared probe 975 is located in the rear end region of the fan motor 92.

[0036] The air-cooled assembly 98 includes an electric push rod 982 fixedly connected to one side of the support frame 91. An L-shaped plate 983 is fixedly connected to the output end of the electric push rod 982, and a guide plate 981 is fixedly connected to the lower side of the L-shaped plate 983.

[0037] The following is a supplementary explanation based on the above structure: the extension and retraction of the output end of the electric push rod 982 is used to move the L-shaped plate 983, thereby causing the guide plate 981 to slide along the guide slider 99. When the output end of the electric push rod 982 extends to one-third of its stroke, the second fan 987 is located in the rear end region of the fan motor 92. When the output end of the electric push rod 982 extends to two-thirds of its stroke, the second fan 987 is located in the middle region of the fan motor 92. When the output end of the electric push rod 982 is fully extended, the second fan 987 is located in the front end region of the fan motor 92.

[0038] The guide plate 981 is slidably connected to the guide slider 99. The inside of the guide plate 981 is provided with a rolling groove. The inside of the guide plate 981 is slidably connected to the second slider 984. A micro motor 989 is fixedly connected to one side of the second slider 984.

[0039] The output end of the micro motor 989 passes through the second slider 984 and is fixedly connected to a roller 985. The outer side of the roller 985 is in contact with the rolling groove, and the lower side of the second slider 984 is fixedly connected to a wind duct 986.

[0040] The following is a supplementary explanation based on the above structure: the rotation of the output end of the micro motor 989 is used to drive the roller 985 to rotate, thereby driving the second slider 984 to rotate along the rolling groove through friction, and then driving the second fan 987 to rotate along the rolling groove, thereby providing air cooling for each area of ​​the fan motor 92.

[0041] A brushless motor 988 is fixedly connected inside the air duct 986, and a second fan 987 is fixedly connected to the output end of the brushless motor 988.

[0042] The following is a supplementary explanation based on the above structure: the rotation of the output end of the brushless motor 988 is used to drive the second fan 987 to rotate, thereby blowing air onto the surface of the fan motor 92 through the air guide tube 986 to dissipate heat from each area of ​​the fan motor 92.

[0043] When the air conditioner is turned on, the outdoor unit's fan motor 92 starts, controlling the first fan 93 to rotate, thereby expelling the heat inside the outdoor unit casing 1. While the first fan 93 is rotating, it controls the guide ring 978 to rotate clockwise. As the guide ring 978 rotates, the guide groove 979 drives the sliding column 974 to slide back and forth in a straight line, thereby driving the infrared sensor 975 to slide back and forth in a straight line. The infrared sensor 975 monitors the surface temperature of each area of ​​the fan motor 92 in real time.

[0044] When the infrared sensor 975 detects a temperature greater than 100 degrees Celsius, the laser transmitter 972 simultaneously emits a laser pulse to the laser receiver 973, calculates the distance between the laser transmitter 972 and the laser receiver 973, and converts the distance value into an electrical signal to be sent to the controller. The controller has a judgment module inside, which is used to accurately determine the heat-generating area of ​​the fan motor 92 by using the distance value between the laser transmitter 972 and the laser receiver 973 when the temperature exceeds 100 degrees Celsius. The controller then controls the second fan 987 to cool the designated heat-generating area via the electric push rod 982. Let the distance value be x.

[0045] When x≤7, the judgment module determines that the rear end of the fan motor 92 is hot. The output end of the electric push rod 982 extends to one-third of its stroke, and the micro motor 989 and the brushless motor 988 start. The brushless motor 988 drives the second fan 987 to enter the field and rotate. The micro motor 989 drives the second fan 987 to rotate along the rolling groove, thereby cooling the rear end area of ​​the fan motor 92 with air.

[0046] When x≤14 and x>7, the judgment module determines that the middle part of the fan motor 92 is hot. The output end of the electric push rod 982 extends to two-thirds of its stroke, and the micro motor 989 and the brushless motor 988 start. The brushless motor 988 drives the second fan 987 to enter the field and rotate. The micro motor 989 drives the second fan 987 to rotate along the rolling groove, thereby cooling the middle part of the fan motor 92.

[0047] When x≤21 and x>14, the judgment module determines that the front end of the fan motor 92 is hot. The output end of the electric push rod 982 is fully extended, and the micro motor 989 and the brushless motor 988 are started. The brushless motor 988 drives the second fan 987 to enter the field and rotate. The micro motor 989 drives the second fan 987 to rotate along the rolling groove, thereby cooling the front end area of ​​the fan motor 92.

[0048] When two areas simultaneously heat up and the distance values ​​are within the ranges of x≤7 and 14≥x>7 respectively, the judgment module determines that the rear end and middle end of the fan motor 92 are simultaneously heating up. The electric push rod 982 extends to two-thirds of its stroke and then retracts completely, repeating this extension and retraction. This causes the second fan 987 to move back and forth between the rear end and middle end of the fan motor 92. The micro motor 989 and the brushless motor 988 start. The brushless motor 988 drives the second fan 987 to enter the field and rotate. The micro motor 989 drives the second fan 987 to rotate along the rolling groove, thereby providing air cooling for one lap of the rear end area and one lap of the middle area of ​​the fan motor 92.

[0049] When two areas simultaneously heat up and the distance values ​​are within the ranges of 14≥x>7 and 21≥x>4 respectively, the judgment module determines that the middle and front ends of the fan motor 92 are simultaneously heating up. The electric push rod 982 extends fully and then retracts to one-third of its stroke, and then extends fully again, repeating this extension and retraction. This causes the second fan 987 to move back and forth between the front and middle ends of the fan motor 92. The micro motor 989 and the brushless motor 988 start. The brushless motor 988 drives the second fan 987 to rotate, and the micro motor 989 drives the second fan 987 to rotate along the rolling groove, thereby providing air cooling for one lap of the middle area and one lap of the front area of ​​the fan motor 92.

[0050] When three areas of heat are simultaneously detected, the judgment module determines that the outdoor unit's fan motor 92 is damaged and needs to be repaired in time. The controller then controls the entire air conditioner to stop immediately.

[0051] By cleverly linking the infrared probe 975 with the guide ring 978 and the guide groove 979, periodic dynamic scanning of the three key areas of the fan motor 92—the front end, middle end, and rear end—is achieved. This is not just simple temperature monitoring; it enables real-time spatial distribution monitoring of the surface temperature of the fan motor 92.

[0052] The laser emitter and laser receiver 972 serve to provide precise physical location coordinates for each high-temperature point detected by the infrared sensor 975. This solves the key problem of "knowing there is heat, but not knowing exactly where it is," converting ambiguous temperature signals into precise location commands that the controller can understand and execute.

[0053] The second fan, driven by the electric actuator 982, is an independent "rapid response unit". Based on the position command issued by the control box 6, it can move directly above the heat source and concentrate the air pressure through the air duct 986 to achieve "targeted elimination" of local hot spots.

[0054] By directly applying cooling resources to the highest temperature area, energy waste caused by overall heat dissipation is avoided, achieving optimal cooling effect with minimal energy consumption, and the heat dissipation efficiency is far higher than existing technologies.

[0055] Furthermore, the system can intervene in advance when the overall temperature of the outdoor unit has not exceeded the standard, but abnormally high temperatures have already appeared in some areas (signs of an impending failure), nipping the problem in the bud and greatly improving the reliability and lifespan of the equipment. This is something that existing overall temperature control systems cannot achieve.

[0056] The concentrated air pressure effectively blows away dust from the surface of the fan motor 92 while cooling the air, breaking the vicious cycle of "dust accumulation → heat insulation → more heat → more dust accumulation" and creating a positive gain.
