Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to an outdoor unit of an air conditioner. Background Art

[0002] When the air conditioner operates in the cooling mode, the outdoor unit is usually in a high-temperature environment. At this time, there is a problem of poor heat dissipation in the electric control box installed in the outdoor unit of the air conditioner.

[0003] In the prior art, the electric control heat dissipation solutions mainly include negative pressure air-cooled heat dissipation and refrigerant heat dissipation. Among them, for negative pressure air-cooled heat dissipation, a ventilation port and a heat exchanger are arranged below the electric control board, and the negative pressure generated when the heat dissipation fan of the air conditioner outdoor unit operates is used to drive heat dissipation.

[0004] However, the heat dissipation effect is limited. For refrigerant heat dissipation, through pipeline design, the refrigerant with a lower temperature after condensation is introduced into the electric control board, but there are higher requirements for the design of the refrigeration system pipeline.

There are also solutions for controlling electric control heat dissipation through a semiconductor cooler and ways of increasing an active heat dissipation fan. These heat dissipation solutions introduce additional power supply loads, pose higher requirements for the electric control of the air conditioner, and have higher costs.

[0047] The embodiments of the present invention will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention will be described in detail below.

[0048] Reference will be made below Figures 1-13 to describe the outdoor unit 100 of an air conditioner according to an embodiment of the present invention.

[0049] Referring to Figures 1-5 as shown, the outdoor unit 100 of an air conditioner according to the first aspect embodiment of the present invention includes: a housing 10, a partition 20, a compressor 30, an outdoor heat exchanger 40, a fan 50, and an electrical box 60.

[0050] The partition 20 is disposed inside the housing 10. The partition 20 divides the internal space of the housing 10 into a compressor chamber 21 and a fan chamber 22. The arrangement of the partition 20 can reduce the noise of the compressor 30 from spreading to the external environment, so that the outdoor unit 100 of the air conditioner can be more silent during operation. Moreover, by dividing the internal space of the housing 10 into a compressor chamber 21 and a fan chamber 22 through the partition 20, it is possible to prevent heat interference between the compressor 30 and the fan 50, and it is also possible to ensure their respective working efficiencies, thereby improving the overall performance of the outdoor unit 100 of the air conditioner.

[0051] The compressor 30 is disposed in the compressor chamber 21, the outdoor heat exchanger 40 is disposed in the fan chamber 22, the first end of the outdoor heat exchanger 40 is connected to the compressor 30, and the compressor 30 and the outdoor heat exchanger 40 perform heat exchange through a refrigerant. The compressor 30 compresses and heats the refrigerant, and then dissipates heat and cools it through the outdoor heat exchanger 40, thereby completing the heat exchange process in the refrigeration cycle.

[0052] The fan 50 is disposed in the fan chamber 22. The fan 50 can discharge the air that has completed heat exchange in the outdoor heat exchanger 40 to the external environment. The electrical box 60 is disposed in the compressor chamber 21. The compression chamber can provide an independent installation space for the compressor 30, which can play a protective role for the compressor 30 and prevent damage to the compressor 30 by external factors such as dust, sand, and rain.

[0053] The electrical box 60 is located above the compressor 30, which can better protect the electrical box 60 from the influence of the external environment, such as rain, dust, etc. This can improve the reliability and durability of the electrical box 60, and also reduce the risk of failures caused by external environmental factors.

[0054] The housing 10 is provided with an air inlet 11, and the air inlet 11 is communicated with the compressor chamber 21, so that the wind in the external environment can enter the compressor chamber 21 through the air inlet 11. The electrical box 60 is provided with a heat dissipation air inlet 61, and the heat dissipation air inlet 61 is communicated with the compressor chamber 21, so that the wind in the compressor chamber 21 can enter the electrical box 60 through the heat dissipation air inlet 61.

[0055] Specifically, the wind in the external environment enters the compressor chamber 21 through the air inlet 11, which can dissipate heat from the compressor 30 and the electrical box 60 in the compressor chamber 21, thereby reducing the temperature of the surrounding environment.

[0056] Furthermore, the electrical box 60 is provided with a heat dissipation air inlet 61, and the heat dissipation air inlet 61 is communicated with the compressor chamber 21, enabling the wind in the compression chamber to enter the interior of the electrical box 60 through the heat dissipation air inlet 61, thus dissipating heat from the control circuit board in the electrical box 60.

[0057] The electrical box 60 is also provided with a heat dissipation air outlet 62, and the heat dissipation air outlet 62 is communicated with the fan chamber 22, so that the heat-exchanged wind in the electrical box 60 can enter the fan chamber 22 through the heat dissipation air outlet 62. The high-speed rotation of the fan 50 in the fan chamber 22 can quickly discharge the air in the fan chamber 22, making it easy to generate negative pressure in the fan chamber 22.

[0058] Since the heat dissipation air inlet 61 is communicated with the compressor chamber 21 and the fan chamber 22 is communicated with the heat dissipation air outlet 62, the fan chamber 22 can be communicated with the compressor chamber 21, enabling the air in the compressor chamber 21 to be quickly discharged, facilitating the formation of negative pressure in the compressor chamber 21, and thus accelerating the air inlet speed of the air inlet 11.

[0059] Among them, the outdoor unit 100 of the air conditioner may include: a cooling heat exchanger 70, which is connected to the second end of the outdoor heat exchanger 40, can play a role in transferring the refrigerant, and can send the refrigerant from the outdoor heat exchanger 40 to the indoor heat exchanger, thereby realizing the refrigeration cycle in the air conditioning system.

[0060] The cooling heat exchanger 70 is arranged in the compressor chamber 21 and is located below the electrical box 60, which can reduce the distance between the cooling heat exchanger 70 and the electrical box 60. In this way, the cooling heat exchanger 70 can control the temperature rise of the electrical box 60, thereby reducing the working temperature of the electrical box 60 and enabling it to be in a normal working temperature environment.

[0061] Also, the wind entering the compressor chamber 21 from the air inlet 11 exchanges heat with the cooling heat exchanger 70 and then enters the electrical box 60 through the heat dissipation air inlet 61, thereby dissipating heat for the electrical box 60.

[0062] Specifically, the external wind enters the interior of the compressor chamber 21 from the air inlet 11, and can dissipate heat from the electrical box 60 inside the compressor chamber 21 for the first time. Moreover, the wind in the compressor chamber 21 exchanges heat with the cooling heat exchanger 70, and the wind after the cooling heat exchanger 70 completes the heat exchange is cold air, and the cold air enters the interior of the electrical box 60 through the heat dissipation air inlet 61, so as to dissipate heat from the devices inside the electrical box 60.

[0063] However, condensed water will be generated during the heat exchange process of the cooling heat exchanger 70, and the flowing down of the condensed water will cause a short circuit in the circuits and electronic devices inside the outdoor unit 100 of the air conditioner, affecting the operation of the outdoor unit 100 of the air conditioner.

[0064] Therefore, the water receiving tray 80 is arranged inside the compressor chamber 21, and the water receiving tray 80 is located below the cooling heat exchanger 70, so that the condensed dew of the cooling heat exchanger 70 can flow into the water receiving tray 80.

[0065] Among them, the condensed water generated during the heat exchange process of the cooling heat exchanger 70 will flow down due to the action of gravity. The water receiving tray 80 is arranged below the cooling heat exchanger 70, which can facilitate the collection of the condensed water generated by the cooling heat exchanger 70, can also prevent the condensed water from splashing, and can also prevent the condensed water from flowing out of the outdoor unit 100 of the air conditioner, thereby improving the safety of the circuits and devices inside the outdoor unit 100 of the air conditioner.

[0066] Thus, in the outdoor unit 100 of the air conditioner, the temperature rise of the electrical box 60 can be controlled through the cooling heat exchanger 70, so as to reduce the operating temperature of the electrical box 60. Moreover, the setting of the water receiving tray 80 can facilitate the collection of the condensed water generated by the cooling heat exchanger 70, can also better restrain the condensed dew, and can also prevent the condensed water from flowing out of the outdoor unit 100 of the air conditioner, thereby improving the safety of the circuits and devices inside the outdoor unit 100 of the air conditioner.

[0067] According to some embodiments of the present invention, as Figure 4 and Figure 5 shown, the cooling heat exchanger 70 and the water receiving tray 80 are arranged on the rear wall of the housing 10, and the cooling heat exchanger 70 is arranged opposite to the air inlet 11, so that the wind at the air inlet 11 can exchange heat with the cooling heat exchanger 70 and then enter the compressor chamber 21.

[0068] Among them, the cooling heat exchanger 70 and the water receiving tray 80 are located on the rear wall of the housing 10, which can reasonably utilize the space inside the outdoor unit 100 of the air conditioner to make its structure more compact.

[0069] The cooling heat exchanger 70 is arranged opposite to the air inlet 11, which can effectively utilize air convection and enhance the heat dissipation effect. When the air enters from the air inlet 11 and passes through the cooling heat exchanger 70, part of the heat is taken away, so as to improve the heat dissipation effect of the cooling heat exchanger 70.

[0070] According to some embodiments of the present utility model, as Figure 5 shown, the water receiving tray 80 is integrally provided with the rear wall of the housing 10, and the water receiving tray 80 is formed by bending the plate material of the housing 10 where the air inlet 11 is opened.

[0071] Among them, the water receiving tray 80 being integrally provided with the rear wall of the housing 10 can effectively prevent the generation of gaps between the water receiving tray 80 and the rear wall of the housing 10, and can also avoid the leakage of condensed water from the gaps, thereby ensuring the waterproof performance of the outdoor unit 100 of the air conditioner.

[0072] Since the water receiving tray 80 is integrally provided with the rear wall of the housing 10, no additional connection steps are required during installation, which can reduce the installation procedures, reduce the number of parts, and also avoid the installation and disassembly of the water receiving tray 80.

[0073] Furthermore, the water receiving tray 80 is formed by bending the plate material of the housing 10 where the air inlet 11 is opened. This method does not require additional components and can directly utilize the bending of the plate material of the air inlet 11 of the housing 10. The structure is simple and compact, can also improve the connection strength between the water receiving tray 80 and the housing 10, reduce the number of parts, and lower the manufacturing cost.

[0074] According to some embodiments of the present utility model, as Figure 5 shown, the water receiving tray 80 includes: a connecting plate 81, the connecting plate 81 is connected to the rear wall of the housing 10, and the connecting plate 81 is attached to the rear wall of the housing 10. In this way, the connecting plate 81 can be more tightly connected to the rear wall of the housing 10, and can also prevent the generation of gaps between the connecting plate 81 and the rear wall of the housing 10, thereby preventing condensed water from flowing into the interior of the outdoor unit 100 of the air conditioner from the gap between the connecting plate 81 and the rear wall of the housing 10.

[0075] The water receiving tray 80 may include: a water guiding plate 82, the water guiding plate 82 is connected to the connecting plate 81, and the water guiding plate 82 can play a role in guiding water, thereby preventing the condensed water on the water receiving tray 80 from accumulating.

[0076] The water receiving tray 80 may include: a water blocking plate 83, the water blocking plate 83 is connected to the water guiding plate 82, and the water blocking plate 83 is disposed opposite to the connecting plate 81. The water blocking plate 83 is connected to the water guiding plate 82. In this way, the water blocking plate 83, the water guiding plate 82, and the water guiding plate 82 together enclose a U-shaped groove, thereby facilitating the collection of rainwater at the gap.

[0077] Furthermore, the water blocking plate 83 is disposed obliquely upward away from the connecting plate 81 relative to the water guiding plate 82, which can play a role in blocking water and also avoid the splashing of rainwater during the process of falling onto the water receiving tray 80.

[0078] Furthermore, the downward projection of the cooling heat exchanger 70 is located within the downward projection of the water receiving tray 80. In this way, it can be ensured that the condensed water completely drips into the water receiving tray 80 under the action of gravity. The baffle 83, the water guide plate 82, and the water guide plate 82 together enclose a U-shaped groove, and the depth of the U-shaped groove can be set to 10 mm.

[0079] Furthermore, the side plates 84 are connected to both ends in the length direction of the water guide plate 82, which can play a role in guiding the water flow direction. The side plates 84 at both ends of the water guide plate 82 can temporarily block part of the condensed water, so as to facilitate the centralized drainage of the water guide plate 82.

[0080] According to some embodiments of the present invention, as Figure 5 and Figure 13 shown, the angle between the baffle 83 and the horizontal plane is α, and α satisfies the relational expression: 30° ≤ α < 90°.

[0081] Among them, the angle α between the baffle 83 and the horizontal plane is not less than the first parameter value. If the angle α between the baffle 83 and the horizontal plane is less than the first parameter value, it will affect the formation of an inclined slope by the baffle 82, resulting in the accumulation of rainwater at the baffle 83. Therefore, the angle α between the baffle 83 and the horizontal plane cannot be less than the first parameter value.

[0082] The value of the first parameter can be from 25° to 30°. Preferably, the first parameter value can be 30°. When the angle α between the baffle 83 and the horizontal plane is 30°, a slope can just be formed between the baffle 83 and the horizontal plane, which can reduce the resistance of the rainwater, thereby accelerating the drainage speed of the rainwater.

[0083] The value range of the angle α between the baffle 83 and the horizontal plane is from 25° to 30°. Preferably, when the angle α between the baffle 83 and the horizontal plane is 30°, the inclination angle of the baffle 83 relative to the horizontal plane is relatively large, so as to ensure the smooth flow of the condensed water on the baffle 83, and the drainage effect is obvious, thereby avoiding the condensed water in the water receiving tray 80 from falling into the compressor chamber 21.

[0084] In addition, the angle α between the baffle 83 and the horizontal plane is less than the second parameter value. If the angle between the baffle 83 and the horizontal plane is greater than or equal to the second parameter value, it will cause the flow velocity of the condensed water to increase when flowing through the baffle 83. This increased flow velocity will cause the condensed water to generate a large kinetic energy when flowing through the baffle 83, resulting in the splashing of the condensed water. In addition, too large an angle will also cause the water flow to separate and form vortices, further increasing the possibility of splashing. Therefore, the angle between the baffle 83 and the horizontal plane cannot be greater than or equal to the second parameter value.

[0085] The value range of the second parameter can be from 40° to 90°. Preferably, when the included angle α between the water baffle 83 and the horizontal plane is 90°, the condensed water dripping on the water guide plate splashes due to excessive flow velocity, and the water baffle 83 cannot collect the condensed water.

[0086] The value range of the included angle α between the water baffle 83 and the horizontal plane is from 40° to 90°. Preferably, when the included angle α between the water baffle 83 and the horizontal plane is 40°, not only can the water droplets at the water baffle 83 be prevented from splashing, but also the drainage effect can be more obvious.

[0087] According to some embodiments of the present invention, as Figure 4 shown, the outdoor unit 100 of the air conditioner may include: a water guide groove 90. The water receiving tray 80 is provided with a water outlet 85, and the water guide groove 90 is connected between the water outlet 85 and the bottom of the housing 10.

[0088] Among them, the setting of the water guide groove 90 can facilitate guiding the water in the water receiving tray 80 from the water outlet 85 to the bottom of the housing 10, and then discharging it to the outside along the drainage channel at the bottom of the housing 10, thereby improving the waterproof performance of the outdoor unit 100 of the air conditioner.

[0089] According to some embodiments of the present invention, as Figure 5 shown, there are multiple water guide grooves 90, and the multiple water guide grooves 90 are arranged at intervals along the length direction of the water receiving tray 80.

[0090] Among them, the condensed water flows evenly in the multiple water guide grooves 90, which can avoid water accumulation or leakage caused by uneven water flow, and can also improve the drainage efficiency of the condensed water.

[0091] Furthermore, the setting of the multiple water guide grooves 90 can effectively reduce the residence time of the condensed water on the water receiving tray 80, reduce the possibility of condensation, and also accelerate the flow of the water in the water receiving tray 80 through the multiple water guide grooves 90 to the bottom of the housing 10.

[0092] In addition, two water guide grooves 90 can be provided, and the two water guide grooves 90 are respectively located at both ends of the water receiving tray 80, so as to further accelerate the drainage speed.

[0093] According to some embodiments of the present invention, the water guide groove 90 is formed by stamping the rear wall of the housing 10.

[0094] Among them, the water guide groove 90 formed by stamping generally has high strength and rigidity, can withstand the influence of water pressure and external environmental forces, and can also prevent the water guide groove 90 from deforming.

[0095] According to some embodiments of the present invention, as Figure 10 and Figure 11As shown, the outdoor unit 100 of the air conditioner may include: a first pipeline 91, which is connected between the second end of the outdoor heat exchanger 40 and the first end of the cooling heat exchanger 70, and a first throttling element 911 is provided on the first pipeline 91.

[0096] Among them, connecting the first pipeline 91 between the second end of the outdoor heat exchanger 40 and the first end of the cooling heat exchanger 70 can facilitate heat transfer and dissipation, thereby improving the overall heat dissipation efficiency.

[0097] Connecting the first pipeline 91 between the second end of the outdoor heat exchanger 40 and the first end of the cooling heat exchanger 70 can achieve more precise temperature control in the air-conditioning system, enabling heat to be regulated and utilized more effectively, which is beneficial to improving the performance and efficiency of the system.

[0098] Also, as Figure 12 shown, the first pipeline 91 is provided with a first throttling element 911. The first throttling element 911 can effectively control the flow rate and flow volume of the fluid, and can also help optimize the working state of the system to ensure the stable flow of the fluid in the pipeline.

[0099] The outdoor unit 100 of the air conditioner may include: a stop valve 92, which is provided on the housing 10. Among them, the stop valve 92 can adjust or completely close the flow of the refrigerant in the air-conditioning system, which is crucial for maintaining the refrigeration effect and operating efficiency of the system. By adjusting the stop valve 92, the flow rate of the refrigerant and the pressure in the air-conditioning system can be controlled, thereby ensuring that the air-conditioning system operates under safe and effective working conditions.

[0100] The outdoor unit 100 of the air conditioner may include: a second pipeline 93, which is connected between the second end of the cooling heat exchanger 70 and the stop valve 92, so as to facilitate the refrigerant to flow to the stop valve 92.

[0101] The outdoor unit 100 of the air conditioner according to the second aspect embodiment of the present invention includes: a housing 10, a partition 20, a compressor 30, an outdoor heat exchanger 40, a fan 50, and an electrical box 60.

[0102] The partition 20 is provided inside the housing 10. The partition 20 divides the internal space of the housing 10 into a compressor chamber 21 and a fan chamber 22. The compressor 30 is provided in the compressor chamber 21, the outdoor heat exchanger 40 is provided in the fan chamber 22, the first end of the outdoor heat exchanger 40 is connected to the compressor 30, the fan 50 is provided in the fan chamber 22, so as to discharge the air heat-exchanged with the outdoor heat exchanger 40 to the external environment, the electrical box 60 is provided in the compressor chamber 21 and above the compressor 30, and the housing 10 is provided with an air inlet 11, and the air inlet 11 is communicated with the compressor chamber 21, so as to enable the air in the external environment to enter the compressor chamber 21 through the air inlet 11.

[0103] Specifically, the partition plate 20 is disposed inside the casing 10. The partition plate 20 divides the internal space of the casing 10 into a compressor chamber 21 and a blower chamber 22. The arrangement of the partition plate 20 can reduce the noise of the compressor 30 from spreading to the external environment, so that the outdoor unit 100 of the air conditioner can be quieter during operation. Moreover, by dividing the internal space of the casing 10 into a compressor chamber 21 and a blower chamber 22 through the partition plate 20, it is possible to prevent heat interference between the compressor 30 and the blower 50, and also ensure their respective working efficiencies, thereby improving the overall performance of the outdoor unit 100 of the air conditioner.

[0104] The compressor 30 is disposed in the compressor chamber 21, and the outdoor heat exchanger 40 is disposed in the blower chamber 22. The first end of the outdoor heat exchanger 40 is connected to the compressor 30. The compressor 30 and the outdoor heat exchanger 40 perform heat exchange through the refrigerant. The compressor 30 compresses and heats the refrigerant, and then dissipates heat and cools down through the outdoor heat exchanger 40, thereby completing the heat exchange process in the refrigeration cycle.

[0105] The blower 50 is disposed in the blower chamber 22. The blower 50 can discharge the air that has completed heat exchange in the outdoor heat exchanger 40 to the external environment. The electrical box 60 is disposed in the compressor chamber 21. The compressor chamber 21 can provide an independent installation space for the compressor 30, which can protect the compressor 30 and prevent damage to the compressor 30 by external factors such as dust, sand, and rain.

[0106] The electrical box 60 is provided with a heat dissipation air inlet 61. The heat dissipation air inlet 61 is communicated with the compressor chamber 21, so that the air in the compressor chamber 21 can enter the electrical box 60 through the heat dissipation air inlet 61. The electrical box 60 is also provided with a heat dissipation air outlet 62. The heat dissipation air outlet 62 is communicated with the blower chamber 22, so that the air after heat exchange in the electrical box 60 can enter the blower chamber 22 through the heat dissipation air outlet 62.

[0107] Among them, the outdoor unit 100 of the air conditioner may include: a cooling heat exchanger 70. The cooling heat exchanger 70 is connected to the second end of the outdoor heat exchanger 40, and the cooling heat exchanger 70 is disposed in the compressor chamber 21.

[0108] The connection between the cooling heat exchanger 70 and the second end of the outdoor heat exchanger 40 can play a role in transferring the refrigerant, and can send the refrigerant from the outdoor heat exchanger 40 to the indoor heat exchanger, thereby realizing the refrigeration cycle in the air conditioning system.

[0109] The cooling heat exchanger 70 is disposed in the compressor chamber 21, and the cooling heat exchanger 70 is located below the electrical box 60. The cooling heat exchanger 70 can control the temperature rise of the electrical box 60, thereby adjusting the working temperature of the electrical box 60 to make it within the normal working temperature range.

[0110] In addition, the air that enters the compressor chamber 21 from the air inlet 11 exchanges heat with the cooling heat exchanger 70 and then enters the electrical box 60 through the heat dissipation air inlet 61, thereby dissipating heat from the electrical box 60.

[0111] Specifically, the outside air enters the interior of the compressor chamber 21 from the air inlet 11, and can dissipate heat from the electrical box 60 inside the compressor chamber 21 for the first time. Moreover, the air in the compressor chamber 21 exchanges heat with the cooling heat exchanger 70. The air after heat exchange by the cooling heat exchanger 70 is cold air, and the cold air enters the interior of the electrical box 60 through the heat dissipation air inlet 61, thereby dissipating heat from the components inside the electrical box 60.

[0112] However, condensed water is generated during the heat exchange process of the cooling heat exchanger 70. The flowing-down of the condensed water may cause a short circuit in the circuits and electronic components inside the outdoor unit 100 of the air conditioner, affecting the operation of the outdoor unit 100 of the air conditioner.

[0113] The outdoor unit 100 of the air conditioner may include: a water receiving tray 80, which is arranged inside the compressor chamber 21 and below the cooling heat exchanger 70, so that the condensed dew of the cooling heat exchanger 70 can flow into the water receiving tray 80.

[0114] Among them, the condensed water generated during the heat exchange process of the cooling heat exchanger 70 will flow down due to the action of gravity. The water receiving tray 80 is arranged below the cooling heat exchanger 70, which can facilitate the collection of the condensed water generated by the cooling heat exchanger 70, can also prevent the condensed water from splashing, and can also prevent the condensed water from flowing out of the outdoor unit 100 of the air conditioner, thereby improving the safety of the circuits and components inside the outdoor unit 100 of the air conditioner.
