Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and more specifically, to an outdoor unit for an air conditioner. Background Technology

[0002] An air conditioner outdoor unit consists of a casing with an outdoor air inlet and an outdoor air outlet. Inside the casing are an outdoor fan and a compressor. To ensure the normal operation of the compressor and outdoor fan, an electrical box is usually installed inside the casing. The electrical box contains a circuit board with electronic components. The electrical box controls the outdoor fan and compressor to achieve the normal operation of the air conditioner outdoor unit. When the air conditioner outdoor unit is operating normally, the electronic components generate a lot of heat. When the temperature of the electronic components is high, it will affect the normal operation of the outdoor fan and compressor. Under normal circumstances, the compressor will reduce its frequency or stop, which seriously affects the stability of the air conditioner outdoor unit. Furthermore, with the miniaturization of electrical boxes, the space inside the electrical box is gradually decreasing, while the density of electronic components is increasing. This makes the heat inside the electrical box more concentrated, making it more likely to affect the outdoor fan and compressor.

[0003] However, the related technology has at least one of the following problems: the components in the air conditioner controller are not arranged reasonably, which causes the components to overheat and fail, reducing the life of the controller. Utility Model Content

[0004] The technical problem solved by this utility model is that the unreasonable arrangement of components in the air conditioner controller in the related technology causes the components to overheat and fail, thus reducing the life of the controller.

[0005] To address the aforementioned problems, this utility model provides an outdoor unit for an air conditioner, comprising: an outdoor unit housing, wherein an air-insulating plate is provided inside the outdoor unit housing to divide the inner cavity of the outdoor unit housing into a compressor chamber and a fan chamber; an electrical control box, the electrical control box comprising a base shell and a circuit board; a baffle plate is formed at one end of the base shell for engaging with a mounting notch on the air-insulating plate, the baffle plate having an air passage hole connecting the fan chamber and the compressor chamber; the circuit board is installed inside the base shell and located at one end of the compressor chamber where the base shell is located, and a high-heat-generating component is provided on the side of the circuit board near the air passage hole; wherein the high-heat-generating component includes at least one of differential mode inductor, electrolytic capacitor, and IPM.

[0006] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: Compared with related technologies, the windproof plate of this utility model is provided with an installation notch, the base shell of the electrical control box is installed on the installation notch, and the shielding plate of the base shell corresponding to the installation notch is provided with a ventilation hole. The compressor chamber and the fan chamber are connected through the ventilation hole. On this basis, the high-heat-generating components are installed on the side of the control circuit board near the ventilation hole. The airflow of the compressor chamber can carry away the heat generated by the high-heat-generating components through the ventilation hole, which is beneficial to the heat dissipation of the high-heat-generating components.

[0007] In one embodiment of this utility model, it further includes: a low-heat-generating component disposed on the circuit board and on the side away from the high-heat-generating component.

[0008] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: low-heating components are placed on the side of the circuit board away from high-heating components, reducing the impact of heat radiation and heat conduction from high-heating components on low-heating components, preventing the performance of low-heating components from being affected by excessively high ambient temperatures, optimizing the overall temperature distribution of components, and improving the stability of the electrical control box.

[0009] In one embodiment of this utility model, the circuit board is further provided with a power device; the outdoor unit of the air conditioner includes: a heat dissipation branch pipe, which is located in the compressor chamber, and part of the structure of the heat dissipation branch pipe is arranged along the vertical direction of the outdoor unit casing and is attached to the power device.

[0010] Compared with existing technologies, the technical effect achieved by adopting this technical solution is: by attaching the heat dissipation branch pipe to the power device, the low-temperature characteristics of the refrigerant are used to force heat dissipation for the power device.

[0011] In one embodiment of this utility model, it further includes: a water baffle plate, which is disposed on the side of the shield plate away from the circuit board, and the water baffle plate and the shield plate cooperate to form an air passage.

[0012] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: the water baffle and the shield plate form an air passage, which not only ensures that the airflow passes through the air passage to dissipate heat from high-heat components, but also prevents water droplets or large dust particles in the fan chamber from entering the base shell through the water baffle. While dissipating heat, the protection level is improved and the risk of moisture failure is reduced.

[0013] In one embodiment of this utility model, the rear end of the baffle is connected to the shield along the front-rear direction of the outer casing.

[0014] Compared with existing technologies, the technical effects achieved by this solution are as follows: the rear end of the water baffle is connected to the shielding plate, which closes the rear end of the air passage in the front-to-back direction, reducing rainwater seepage from the rear; at the same time, it enhances the installation strength of the water baffle, avoids deformation of the water baffle due to the impact of the fan airflow, and ensures stable water blocking and ventilation effects.

[0015] In one embodiment of this utility model, the upper end of the baffle plate is connected to the shield plate along the vertical direction of the outer casing.

[0016] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: the upper part of the water baffle is connected to the shield, which closes the upper part of the air passage along the vertical direction, effectively preventing rainwater or condensation dripping from the top from entering the base shell. Combined with the rear connection structure, it forms a more comprehensive waterproof barrier, taking into account both ventilation and protection, and further improving the reliability of the electronic control components in complex environments.

[0017] In one embodiment of this utility model, there are at least two baffles along the front-to-back direction; along the left-to-right direction of the outer casing, the first projection of at least one baffle onto the shielding plate and the second projection of the adjacent baffle onto the shielding plate at least partially overlap.

[0018] Compared with existing technologies, the technical effects achieved by this solution are as follows: multiple water baffles are arranged in the left-right direction and their projected portions overlap to form an "interlaced shielding" structure. Even if rainwater flows in through the gaps in one of the water baffles, it will be blocked by the adjacent water baffles, greatly improving the waterproof effect. At the same time, it does not affect the airflow entering the air passage through the gaps in the overlapping areas, ensuring heat dissipation efficiency.

[0019] In one embodiment of this utility model, the water baffle includes: a first blocking member and a second blocking member, the first blocking member and the second blocking member having at least partial structural overlap; along the vertical direction, the lower end of the second blocking member is connected to the first blocking member; or, the lower end of the first blocking member is connected to the second blocking member.

[0020] Compared with the existing technology, the technical effects achieved by adopting this technical solution are as follows: the first shielding component and the second shielding component partially overlap and are connected vertically to form a stepped shielding in the vertical direction, blocking rainwater from flowing in from above or diagonally below; the overlapping structure ensures that there is no direct rain leakage channel, and the connection method is simple and easy to assemble.

[0021] In one embodiment of this utility model, it further includes: a diversion plate, which is disposed on the side of the baffle plate close to the circuit board, and the diversion plate and the baffle plate cooperate to form a diversion air duct.

[0022] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the airflow guide plate and the baffle plate form an airflow channel, which concentrates the airflow entering from the air passage to the area where the high-heat-generating components are located, enhances the direct impact of the airflow on the high-heat-generating components, and improves the heat dissipation efficiency; at the same time, it avoids the energy waste caused by the disorderly flow of airflow in the base shell.

[0023] In one embodiment of this utility model, the electrical control box is vertically arranged along the up-down direction of the outer casing, and the thickness direction of the electrical control box is the same as the front-back direction of the outer casing. The electrical control box is located at the installation notch.

[0024] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: the electrical control box is vertically installed along the height of the outer casing, and its thickness direction is consistent with the front and rear direction of the outer casing, so that it can be compactly installed at the installation notch of the windproof upright plate, saving the compressor chamber space, avoiding interference, and facilitating airflow to enter the electrical control box for heat dissipation through the air vents.

[0025] By adopting the technical solution of this utility model, the following technical effects can be achieved: (1) The windproof upright plate of this utility model is provided with an installation notch, the base shell is installed on the installation notch, and the shielding plate corresponding to the installation notch of the base shell is provided with a ventilation hole. The compressor chamber and the fan chamber are connected through the ventilation hole. On this basis, the high heat generation components are installed on the side of the circuit board close to the ventilation hole. The airflow of the fan chamber can carry away the heat generated by the high heat generation components through the ventilation hole, which is beneficial to the heat dissipation of the high heat generation components. The low heat generation components are placed on the side of the circuit board away from the high heat generation components, which reduces the impact of the heat radiation and heat conduction of the high heat generation components on the low heat generation components, avoids the performance of the low heat generation components being affected by the high ambient temperature, optimizes the temperature distribution of the overall components, and improves the stability of the electrical control box. (2) In this utility model, the water baffle and the shield plate are spaced apart to form an air passage, which not only ensures that the airflow passes through the air passage to dissipate heat for the high-heat components, but also prevents water droplets or large dust particles in the fan chamber from entering the base shell through the water baffle, thereby improving the protection level and reducing the risk of moisture failure while dissipating heat. (3) In this utility model, multiple water baffles are arranged along the left and right directions and their projected parts overlap to form an “interlaced shielding” structure. Even if rainwater flows in from the gap of a certain water baffle, it will be blocked by the adjacent water baffle, which greatly improves the waterproof effect. At the same time, it does not affect the airflow entering the air passage through the gap of the overlapping area, thus ensuring heat dissipation efficiency. Attached Figure Description

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0031] See Figure 1 , Figure 1 A schematic diagram of the structure of an outdoor unit of an air conditioner provided for an embodiment of this utility model; combined with Figures 2 to 8 Specifically, the outdoor unit 100 of the air conditioner includes: an outdoor unit housing 10 and an electrical control box 30; wherein, the outdoor unit housing 10 is provided with a windproof plate 20 to divide the inner cavity of the outdoor unit housing 10 into a compressor chamber 12 and a fan chamber 11; the electrical control box 30 includes a base shell 31 and a circuit board 32; wherein, one end of the base shell 31 is formed with a baffle plate 311 for cooperating with the mounting notch 21 on the windproof plate 20, and the baffle plate 311 has an air passage 312 connecting the fan chamber 11 and the compressor chamber 12; the circuit board 32 is installed in the base shell 31 and is located on the side of the base shell 31 closer to the compressor chamber 12, and a high-heat-generating component 33 is provided on the side of the circuit board 32 closer to the air passage 312.

[0032] Preferably, the high-heat-generating component 33 includes at least one of differential mode inductor 331, electrolytic capacitor 332, and IPM 333.

[0033] Furthermore, the circuit board 32 includes a first end face 321 and a second end face 322 disposed opposite to each other; a high-heat-generating component 33 is disposed on the first end face 321.

[0034] For further information, please refer to [link / reference]. Figure 4 and Figure 5 The outdoor unit 100 of the air conditioner includes: a low-heating component 34, which is disposed on the circuit board 32 and on the side away from the high-heating component 33.

[0035] It should be noted that the low-heating component 34 on the circuit board 32 can be placed on the same side as the high-heating component 33, but needs to be far away from the high-heating component 33; or it can be placed on two different end faces of the circuit board 32 with the high-heating component 33.

[0036] Optionally, the low-heating component 34 is disposed on the first end face 321 and away from the high-heating component 33, or the low-heating component 34 is disposed on the second end face 322 and away from the high-heating component 33.

[0037] Specifically, please refer to Figure 4 and Figure 5 The circuit board 32 is mounted on the base shell 31. The high-heat-generating component 33 is mounted on the side of the circuit board 32 near the air vent 312 on the shield plate 311. The low-heat-generating component 34 is mounted on the first end face 321 of the circuit board 32, and is located away from the high-heat-generating component 33.

[0038] Based on specific operating conditions, when the outdoor unit 100 of the air conditioner is running, the fan in the fan chamber 11 drives the fan blades to rotate at high speed, forming a high-speed airflow within the fan chamber 11, thus creating a large negative pressure within the fan chamber 11. The baffle plate 20 divides the outer casing 10 into the fan chamber 11 and the compressor chamber 12, and cooperates with the air vent 312 on the base casing 31, allowing the fan chamber 11 and the compressor chamber 12 to communicate, meaning only the air vent 312 allows air circulation between the compressor chamber 12 and the fan chamber 11. However, when the outdoor unit 100 is operating normally... During operation, there is a large pressure difference between the compressor chamber 12 and the fan chamber 11. The air in the compressor chamber 12 flows out through the air passage 312, thus forming a high-speed airflow at the air passage 312. The high-heat component 33 is located on the side of the circuit board 32 close to the air passage 312. When the high-speed airflow passes over the high-heat component 33, it can quickly carry away the heat on the surface of the high-heat component 33, preventing the high-heat component 33 from overheating due to heat accumulation. This allows the high-heat component 33 to operate stably for a long time, improves its service life, and improves the quality of the electrical control box 30.

[0039] Furthermore, the low-heat-generating component 34 is disposed on the first end face 321 of the circuit board 32, away from the high-heat-generating component 33. This ensures that when the outdoor unit 100 is operating normally, the low-heat-generating component 34 generates less heat and experiences a lower temperature rise. On the one hand, it prevents overheating and failure due to insufficient heat dissipation. On the other hand, because the low-heat-generating component 34 generates less heat, the heat carried away by the airflow from the compressor chamber 12 to the fan chamber 11 is also not very high. Therefore, when the airflow passes from the low-heat-generating component 34 to the high-heat-generating component 33, it will not significantly affect the temperature of the component. The increase in temperature is not too significant. Conversely, if the low-heating component 34 is located on the side of the circuit board 32 near the air vent 312, while the high-heating component 33 is located on the side of the circuit board 32 away from the low-heating component 34, the airflow will carry away a large amount of heat when passing through the high-heating component 33, causing the temperature of the low-heating component 34 at the air vent 312 to rise rapidly, which may cause the low-heating component 34 to fail. Therefore, placing the low-heating component 34 on the side of the circuit board 32 away from the high-heating component 33 can effectively reduce the overall temperature of the electrical control box 30.

[0040] For further information, please refer to [link / reference]. Figure 7 and Figure 8 The circuit board 32 is also equipped with a power device 35; the outdoor unit 100 of the air conditioner includes: a heat dissipation branch pipe 40; the heat dissipation branch pipe 40 is located in the compressor chamber 12, and part of the structure of the heat dissipation branch pipe 40 is arranged along the vertical direction of the outdoor unit casing 10 and is in contact with the power device 35; and one end of the heat dissipation branch pipe 40 is connected to the liquid outlet pipe 50 of the heat exchanger, and the other end is connected to the liquid outlet valve 60.

[0041] Preferably, the power device 35 is disposed on the second end face 322 of the circuit board 32.

[0042] Preferably, the power device 35 is disposed at the middle position of the second end face 322.

[0043] In practice, power device 35 is a high-heat-generating component that generates a large amount of heat during normal operation. It is placed on the second end face 322 of circuit board 32 to isolate it from high-heat-generating component 33. Then, power device 35 is attached to heat dissipation branch pipe 40, and heat dissipation is achieved by the refrigerant in heat dissipation branch pipe 40. Since one end of heat dissipation branch pipe 40 is connected to the liquid outlet pipe 50 of heat exchanger and the other end is connected to liquid outlet valve 60, the refrigerant in heat dissipation branch pipe 40 is always in a flowing state. The refrigerant passing through power device 35 is always at a low temperature, which can carry away the heat on power device 35 in time and can significantly reduce the temperature rise of power device 35.

[0044] For further information, please refer to [link / reference]. Figures 4 to 6 The air conditioner also includes a water baffle 36; the water baffle 36 is located on the side of the shield 311 away from the circuit board 32, and the water baffle 36 and the shield 311 cooperate to form an air passage 361.

[0045] Furthermore, along the front-rear direction of the outer casing 10, the rear end of the baffle 36 is connected to the shield 311.

[0046] Furthermore, along the vertical direction of the outer casing 10, the upper end of the baffle plate 36 is connected to the shield plate 311.

[0047] Please see Figures 4 to 6 Specifically, the baffle plate 36 is mounted on the base shell 31 and located in the fan chamber 11 to prevent water or dust in the fan chamber 11 from entering the compressor chamber 12 through the air passage 312. The rear end of the baffle plate 36 is connected to the shield plate 311 to seal the rear end of the shield plate 311, reducing rainwater seepage from the rear of the fan chamber 11 into the air passage 361. At the same time, it prevents the baffle plate 36 from deforming due to the impact of the fan airflow. Similarly, the upper end of the baffle plate 36 is connected to the shield plate 311 to seal the upper end of the shield plate 311, which can effectively prevent water droplets or condensate from the top of the fan chamber 11 from entering the compressor chamber 12. Together with the rear end of the baffle plate 36, a more comprehensive waterproof barrier is formed.

[0048] Furthermore, in the front-to-back direction, there are at least two water deflectors 36; in the left-to-right direction of the outer casing 10, the first projection of at least one water deflector 36 onto the shield 311 at least partially overlaps with the second projection of the adjacent water deflector 36 onto the shield 311.

[0049] Specifically, please refer to Figure 5The water baffle 36 includes: a first shielding member 362 and a second shielding member, the first shielding member 362 and the second shielding member having at least partial structural overlap; along the vertical direction, the lower end of the second shielding member is connected to the first shielding member 362; or, the lower end of the first shielding member 362 is connected to the second shielding member.

[0050] Preferably, the first blocking member 362 is an inner blocking member, and the second blocking member is an outer blocking member; wherein the lower end of the outer blocking member is connected to the inner blocking member.

[0051] For further information, please refer to [link / reference]. Figure 5 The base shell 31 is also provided with a support member 38, and the support member 38 is provided with a baffle plate 311 on the side close to the water baffle plate 36; to prevent the water baffle plate 36 from blocking the air passage 312 when it is damaged, so that there is always an air passage 361 between the baffle plate 311 and the water baffle plate 36.

[0052] Preferably, there are multiple support members 38, which are arranged at intervals along the vertical direction of the outer casing 10.

[0053] For further information, please refer to [link / reference]. Figure 4 and Figure 5 The outdoor unit 100 of the air conditioner also includes a deflector plate 37, which is located on the side of the shield plate 311 near the circuit board 32, and the deflector plate 37 and the shield plate 311 cooperate to form a deflector air duct 371.

[0054] Specifically, a flow guide plate 37 is provided on the base shell 31. The flow guide plate 37 and the baffle plate 311 cooperate to form a flow guide air duct 371, so that the airflow in the compressor chamber 12 is guided to the baffle plate 311 and enters the fan chamber 11 through the air passage hole 312 on the baffle plate 311. Before the airflow enters the fan chamber 11, the high heat-generating components 33 near the air passage hole 312 will be flushed to reduce the temperature of the high heat-generating components 33.
