[0003] An air conditioner generally includes an indoor unit and an outdoor unit. The outdoor unit includes an outdoor unit casing, a compressor, a condenser, a fan and an electrical control box component. The electrical control box component includes a box body and electrical components housed in the box body. The electrical components may include a main control board and an inverter computer board. There are many electronic components on the main control board and the inverter computer board, and they are compactly arranged, which results in high heat, that is, the temperature of the electrical components is high. Since the temperature of the electrical components is too high, it will affect the service life of the electronic components. Therefore, the existing technology usually dissipates heat for the electrical components.

[0004] In the prior art, heat dissipation for electronic components is usually carried out by combining refrigerant heat dissipation and air cooling. However, the cost of refrigerant heat sinks is high, while the heat dissipation capacity of air cooling is insufficient, thus making the service life of electronic components still relatively short.

[0015] In an embodiment of the present invention, it also includes an on-off component, a heater and an outdoor fan; the on-off component is arranged in the external unit housing and is located at the third air outlet, and the external unit housing also has a fourth air outlet; the heater is arranged in the clothing storage chamber for drying the clothing located in the clothing storage chamber; the external unit housing has an air inlet side and an air outlet side, the air inlet side has an air inlet, and the air outlet side has a third air outlet and a fourth air outlet; the outdoor fan and the condenser are arranged in sequence in the external unit housing along the direction from the air inlet side to the air outlet side; when the air conditioner outdoor unit is in heating mode, the on-off component disconnects the connection between the external unit housing and the dryer housing, and the heater is turned on.

[0031] Figures 1 to 5 The air-conditioning outdoor unit and air-conditioning provided by the present invention are shown. As can be seen from the figure, the air-conditioning outdoor unit provided by the present invention includes an outer housing 100, a first heat sink 200, an electrical control unit 300 and a second heat sink 400. The first heat sink 200 is arranged in the outer housing 100, and a first heat sink 200 has a first heat dissipation duct, which can be connected to the first air inlet 210 and the first air outlet 220 arranged on the first heat sink 200; the electrical control unit 300 is connected to the first heat sink 200; the second heat sink 400 is arranged in the outer housing 100, and a second heat dissipation duct is provided inside the first heat sink 200 and the second heat sink 400, which can be connected to the second air inlet 410 and the second air outlet 420 arranged on the second heat sink 400, and the electrical control unit 300 is located in the second heat dissipation duct.

[0032] In the air-conditioning outdoor unit of the present invention, the electrical control unit 300 is connected to the first heat sink 200. The electrical control unit 300 can transfer heat to the first heat sink 200, and the first heat sink 200 has a first heat dissipation duct inside. Cold air (or first cold air) enters the first heat sink 200 through the first air inlet 210 and flows in the first heat dissipation duct inside the first heat sink 200. The cold air carries the heat transferred from the electrical control unit 300 to the first heat sink 200 and becomes hot air. The hot air flows out to the external environment through the first air outlet 220. The cold and hot air circulate alternately over and over again to complete the uninterrupted heat exchange between the electrical control unit 300 and the external environment, ensuring that the electrical control unit 300 always has good thermal conductivity.

[0033] In addition, the electrical control unit 300 is located in the second heat dissipation duct, and cold air (or second cold air) enters the second heat dissipation element 400 through the second air inlet 410 and flows in the second heat dissipation duct inside the second heat dissipation element 400. The cold air carries the heat dissipated outward by the electrical control unit 300 (electronic components) and becomes hot air. The hot air flows out to the external environment through the second air outlet 420. The cold and hot air circulate alternately over and over again to complete the uninterrupted heat exchange between the electrical control unit 300 and the external environment, ensuring that the electrical control unit 300 always has good thermal conductivity.

[0034] In summary, the present invention does not require the installation of a refrigerant radiator, so the cost is low. Moreover, by setting up dual heat dissipation ducts (a first heat dissipation duct and a second heat dissipation duct), the heat dissipation capacity of air cooling can be improved to solve the technical problem in the prior art that the cost of the refrigerant radiator is high and the heat dissipation capacity of air cooling is insufficient, resulting in a short service life of the electronic components of the electrical control unit 300.

[0035] According to one embodiment of the present invention, the air-conditioning outdoor unit of the present invention may further include an outdoor fan 500, which is arranged in the outer unit housing 100 and is used to dissipate heat from the electrical control unit 300. Driven by the outdoor fan 500, air enters the first heat dissipation duct from the first air inlet 210 and flows out from the first air outlet 220.

[0036] In this embodiment, the outdoor fan 500 is further configured to allow air to enter the second heat dissipation duct from the second air inlet 410 and to flow out from the second air outlet 420 to dissipate heat from the surface of the electrical component 300 .

[0037] During specific implementation, the outdoor fan 500 can be an axial fan. The outdoor fan 500 serves as a power source and can make the air in the first heat dissipation duct and the second heat dissipation duct flow. The outdoor fan 500 can be electrically connected to the electrical control unit 300. Thus, under the drive of the outdoor fan 500, air can quickly enter the first heat dissipation duct from the first air inlet 210 and flow out from the first air outlet 220 to dissipate heat for the electrical control unit 300 and improve the heat dissipation capacity of the electrical control unit 300.

[0038] In a feasible embodiment, the electrical control unit 300 may include an inverter computer board 310 and a main control board 320; the inverter computer board 310 is connected to the first heat sink 200, the main control board 320 is connected to the external housing 100, and the first heat dissipation duct is connected to the second heat dissipation duct through the first air outlet 220 facing the main control board 320.

[0039] During specific implementation, cold air enters the first heat sink 200 from the first air inlet 210 and flows in the first heat dissipation duct inside the first heat sink 200. The cold air carries the heat transferred from the inverter computer board 310 to the first heat sink 200 and becomes hot air. The hot air flows to the second heat dissipation duct through the first air outlet 220. In addition, the cold air can also enter the second heat sink 400 through the second air inlet 410 and flow in the second heat dissipation duct inside the second heat sink 400. The cold air is mixed with the air flowing out of the first heat dissipation duct to make the airflow larger. The mixed air is blown toward the main control board 320 together, exchanges heat with the main control board 320, and flows out from the second air outlet 420, thereby improving the heat dissipation capacity of the electrical control unit 300.

[0040] In an embodiment of the present invention, the second heat sink 400 has a first end and a second end arranged along the thickness direction T of the air conditioner outdoor unit, and a second air inlet 410 is provided at the positions of the first end and the second end corresponding to the inverter computer board 310.

[0041] During specific implementation, cold air can enter from the second air inlet 410 set at the first end, and can also enter from the second air inlet 410 set at the second end. As a result, the amount of cold air entering the second heat dissipation duct is greater, which can better exchange heat with the inverter computer board 310 and the main control board 320, further improving the heat dissipation capacity of the electrical control unit 300.

[0042] In an embodiment of the present invention, the second air outlet 420 is provided at a position corresponding to the main control board 320 at the first end and / or the second end.

[0043] During specific implementation, cold air enters the first heat sink 200 from the first air inlet 210 and flows in the first heat dissipation duct inside the first heat sink 200. The cold air carries the heat transferred from the inverter computer board 310 to the first heat sink 200 and becomes hot air. The hot air flows to the second heat dissipation duct through the first air outlet 220. In addition, the cold air can also enter the second heat sink 400 through the second air inlet 410 and flow in the second heat dissipation duct inside the second heat sink 400. The cold air is mixed with the air flowing out of the first heat dissipation duct. The mixed air is blown toward the main control board 320 together and exchanges heat with the main control board 320. Since the position of the second air outlet 420 corresponds to the position of the main control board 320, the air can flow out from the second air outlet 420 faster, the heat dissipation efficiency is higher, and the heat dissipation capacity of the electrical control unit 300 is further improved.

[0044] In another feasible embodiment, the electrical control unit 300 may include an inverter computer board 310 and a main control board 320; the main control board 320 is connected to the first heat sink 200, the inverter computer board 310 is connected to the external housing 100, and the first heat dissipation duct is connected to the second heat dissipation duct through the first air outlet 220 facing the inverter computer board 310.

[0045] During specific implementation, cold air enters the first heat sink 200 from the first air inlet 210 and flows in the first heat dissipation duct inside the first heat sink 200. The cold air carries the heat transferred from the main control board 320 to the first heat sink 200 and becomes hot air. The hot air flows to the second heat dissipation duct through the first air outlet 220. In addition, the cold air can also enter the second heat sink 400 through the second air inlet 410 and flow in the second heat dissipation duct inside the second heat sink 400. The cold air is mixed with the air flowing out of the first heat dissipation duct to make the airflow larger. The mixed air is blown toward the inverter computer board 310 together, exchanges heat with the inverter computer board 310, and flows out from the second air outlet 420, thereby improving the heat dissipation capacity of the electrical control unit 300.

[0046] According to one embodiment of the present invention, a fan accommodating chamber 110 is provided in the outer unit casing 100, and the outdoor fan 500 is arranged in the fan accommodating chamber 110. The first air inlet 210 is located on one side of the outdoor fan 500 along the horizontal direction B of the air-conditioning outdoor unit, and the first air inlet 210 is connected to the fan accommodating chamber 110. The second air outlet 420 is located at the top of the outdoor fan 500, and the second air outlet 420 is connected to the fan accommodating chamber 110.

[0047] In a specific implementation, when the outdoor fan 500 (fan blades) rotates counterclockwise, cold air enters the first heat sink 200 from the first air inlet 210 and flows in the first heat dissipation duct inside the first heat sink 200. The cold air carries the heat transferred from the inverter computer board 310 to the first heat sink 200 and turns into hot air. The hot air flows to the second heat dissipation duct through the first air outlet 220. In addition, the cold air can also enter the second heat sink 400 through the second air inlet 410. The cold air flows in the second heat dissipation duct of the outer shell, and the cold air mixes with the air flowing out of the first heat dissipation duct. The mixed air is blown toward the main control board 320 together, and exchanges heat with the main control board 320. The hot air after the heat exchange flows from the second air outlet 420 to the fan accommodating chamber 110, and is accelerated to flow to the external environment under the rotation of the outdoor fan 500. The cold and hot air circulate alternately and repeatedly to complete the uninterrupted heat exchange between the electrical control unit 300 and the external environment, thereby ensuring that the electrical control unit 300 always has good thermal conductivity.

[0048] When the outdoor fan 500 (fan blades) rotates clockwise, cold air enters the second heat sink 400 from the second air outlet 420 and flows in the second heat dissipation duct inside the second heat sink 400. The cold air carries the heat dissipated from the main control board 320 and turns into hot air. A part of the hot air flows out to the external environment through the second air inlet 410. The cold and hot air circulate alternately and repeatedly to complete the uninterrupted heat exchange between the electrical control unit 300 and the external environment, ensuring that the electrical control unit 300 always has good thermal conductivity; the other part of the hot air can also flow out through the second air inlet 410 to the external environment. An air outlet 220 enters the interior of the first heat sink 200 and flows in the first heat dissipation duct inside the first heat sink 200. The hot air carries the heat transferred to the first heat sink 200 by the inverter computer board 310 and becomes hotter air. The air flows into the fan accommodating chamber 110 through the first air inlet 210 and is accelerated to flow into the external environment under the rotation of the outdoor fan 500. The cold and hot air circulate alternately and repeatedly to complete the uninterrupted heat exchange between the electrical control unit 300 and the external environment, ensuring that the electrical control unit 300 always has good thermal conductivity.

[0049] The present invention also provides an air conditioner including the air conditioner outdoor unit of the above embodiment, comprising an outer housing 100, a compressor 600, a condenser 700, and a dryer housing 800. The outer housing 100 has a third air outlet 120. The compressor 600 and the condenser 700 can be disposed within the outer housing 100. The dryer housing 800 communicates with the outer housing 100 via the third air outlet 120. The dryer housing 800 has a clothing storage chamber 810 for storing clothing. When the air conditioner outdoor unit is in cooling mode, the condenser 700 can release heat into the clothing storage chamber 810 to dry the clothing within. The specific structure, operating principle, and beneficial effects of the air conditioner outdoor unit are the same as those of the above embodiment and are not further described here.

[0050] In specific implementation, when clothes need to be dried, the clothes to be dried can be placed in the clothes storage chamber 810. Since, when the air-conditioning outdoor unit is in cooling mode, the condenser 700 can release heat into the clothes storage chamber 810, the clothes in the clothes storage chamber 810 can be dried.

[0051] According to one embodiment of the present invention, the air conditioner of the present invention may further include an on-off component 900 (such as a valve), a heater 910 and an outdoor fan 500; the on-off component 900 is arranged in the external housing 100 and is located at the third air outlet 120, and the external housing 100 also has a fourth air outlet 130; the heater 910 is arranged in the clothing accommodating cavity 810, and is used to dry the clothing located in the clothing accommodating cavity 810, the external housing 100 has an air inlet side and an air outlet side, the air inlet side has an air inlet 140, and the air outlet side has a third air outlet 120 and a fourth air outlet 130, the outdoor fan 500 and the condenser 700 are arranged in sequence in the external housing 100 along the direction from the air inlet side to the air outlet side; when the air conditioner outdoor unit is in heating mode, the on-off component 900 disconnects the connection between the external housing 100 and the dryer housing 800, and the heater 910 is turned on.

[0052] It is understandable that when clothes need to be dried, the clothes can be placed in the clothes storage chamber 810. Since the condenser 700 will release heat in the cooling mode, and the on-off component 900 can connect the external unit housing 100 and the dryer housing 800, under the action of the outdoor fan 500, the outdoor fan 500 can make the air entering the external unit housing 100 from the air inlet 140 of the external unit housing 100 pass through the condenser 700 in sequence so that the air is heated by the condenser 700, and then the heated air flows into the clothes storage chamber 810, thereby drying the clothes placed in the clothes storage chamber 810. The heat released by the condenser 700 in the cooling mode is used to evaporate and dry the moisture in the washed clothes in the clothes storage chamber 810. In this way, the energy utilization rate can be improved, energy can be saved, and the hot air blown out by the air-conditioning outdoor unit can be prevented from being directly discharged into the atmosphere, causing energy waste.

[0053] In addition, since the condenser 700 absorbs heat in the heating mode, if the external housing 100 and the dryer housing 800 are connected, the ambient temperature in the dryer housing 800 will be lowered, affecting the drying efficiency of the clothes in the clothing storage chamber 810. Therefore, when the air conditioner outdoor unit is in the heating mode, the on-off component 900 disconnects the connection between the external housing 100 and the dryer housing 800, and the heater 910 is turned on. Under the action of the outdoor fan 500, the outdoor fan 500 can make the air enter from the air inlet 140 to the external housing 100. 00 passes through the condenser 700 in sequence and then flows out from the second air outlet 420. Since the air that exchanges heat with the condenser 700 does not enter the clothing accommodating chamber 810 through the first air outlet 220, the ambient temperature in the dryer housing 800 will not be reduced, and the drying efficiency of the clothing in the clothing accommodating chamber 810 will not be affected. The clothing placed in the clothing accommodating chamber 810 can be dried by turning on the heater 910 provided in the dryer housing 800, that is, it can neither affect the heating of the air conditioner nor affect the drying of the clothing.

[0054] It is understandable that energy issues are becoming increasingly serious nowadays. In the field of refrigeration, reducing energy consumption and improving energy utilization are the issues that are currently being focused on in the air-conditioning industry. When the air conditioner is in cooling mode, the indoor unit of the air conditioner brings a comfortable and cool experience to the user, while the hot air blown out by the outdoor unit of the air conditioner is directly transmitted to the outdoors, resulting in energy waste.
