Detailed Embodiments

[0031] To enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0032] As described in the background art, refer to Figure 1 , the traditional radiator structure is divided into two parts: the radiator main body and the radiator fixing plate 102. The radiator is fixed on the outdoor unit main board by welding the pins on the radiator main body. The radiator main body has a refrigerant inlet and outlet pipe placement groove to achieve large-area contact with the refrigerant pipe of the radiator outdoor unit. The radiator fixing plate 102 and the radiator main body clamp the refrigerant inlet and outlet pipe 101 in the middle for fixation. The temperature of the refrigerant pipe is much lower than the ambient and component temperatures, so the heat around it can be taken away. To improve the thermal conductivity, thermal grease needs to be applied between the refrigerant inlet and outlet pipe 101 and the heat dissipation main body. However, this heat dissipation structure only through the refrigerant has limited cooling capacity and a small affected area for cooling.

[0033] According to an embodiment of the present invention, an outdoor unit of an air conditioner is provided. Please refer to Figures 1 to 8 , including: a housing 1, in which a device cavity and a blower cavity 11 with a blower 12 installed are provided; a radiator 2, the radiator 2 is connected to a component to be cooled 3 located in the device cavity to dissipate heat from the component to be cooled 3; a duct 4, the duct 4 includes a first air inlet 41 and a duct main body 42 communicated with the first air inlet 41, and the duct main body 42 covers the radiator 2; a gas collecting component 5, the gas collecting component 5 is located in the blower cavity 11, the gas collecting component 5 includes a gas collecting port 51 and a gas collecting cavity 52 communicated with the gas collecting port 51, the opening direction of the gas collecting port 51 faces the blower 12, the gas collecting component 5 includes a gas collecting outlet 53 communicated with the gas collecting cavity 52, and the gas collecting outlet 53 is communicated with the first air inlet 41 to guide the airflow generated by the blower 12 into the duct main body 42.

[0034] Specifically, the blower 12 sends the airflow into the gas collecting component 5, the airflow is collected through the gas collecting component 5, and the airflow is introduced into the duct main body 42. The temperature of the airflow from the blower 12 is lower than the temperature of the radiator 2, and it can quickly take away the heat of the radiator 2, thereby cooling the component to be cooled 3. The gas collecting component 5 and the duct structure in this embodiment can blow the air blown out by the blower 12 into the radiator through the duct, solving the technical problem in the related art that the heat dissipation capacity of the traditional structure radiator is limited and the heat of the heating components on the outdoor unit main board cannot be quickly taken away.

[0035] Specifically, the component to be cooled 3 includes, but is not limited to, components such as the main board and components in the outdoor unit of the air conditioner.

[0036] Specifically, the outdoor unit of the air conditioner further includes a basic air duct 46, and the first air inlet 41 is connected to the air duct main body 42 through the basic air duct 46.

[0037] In the outdoor unit of the air conditioner in this embodiment, refer to Figure 2 , a gas collecting port 51 is provided at one end of the gas collecting cavity 52, a collecting area 54 is provided at the other end of the gas collecting cavity 52, and the cross-sectional area of the gas collecting cavity 52 gradually decreases from the gas collecting port 51 to the collecting area 54, so that the air flow entering the gas collecting cavity 52 is collected in the collecting area 54; wherein, the collecting area 54 is disposed opposite to the gas collecting outlet 53. Specifically, the gas collecting cavity 52 is funnel-shaped, that is, the end where the gas collecting port 51 is located is the large end, and the end where the collecting area 54 is located is the small end. The air flow is guided by the inner wall of the gas collecting component 5 and is collected from the large end to the small end collecting area 54. The collecting area 54 is disposed opposite to the gas collecting outlet 53, and the air pressure in the collecting area 54 is greater than the air pressure at the gas collecting outlet 53, forming an obvious pressure difference. The air flow in the collecting area 54 gushes out through the gas collecting outlet 53, thereby improving the gas collecting efficiency of the gas collecting component 5.

[0038] In the outdoor unit of the air conditioner in this embodiment, refer to Figure 2 , the outdoor unit of the air conditioner includes a grille 6 spaced apart from the fan 12, and a gas collecting component 5 is fixedly installed on the grille 6. Specifically, the end of the gas collecting cavity 52 close to the grille 6 is the small end. In this embodiment, the gas collecting component 5 collects the air blown out by the fan 12 and introduces it into the air duct. In this working mode, it is not necessary to turn on an additional fan to achieve the air-cooling effect. While simplifying the equipment structure, the air blown out by the fan is recycled, saving energy consumption.

[0039] In the outdoor unit of the air conditioner in this embodiment, refer to Figure 3 , the air duct 4 includes a reinforced air duct 43, and the reinforced air duct 43 includes a second air inlet 431 and a second air outlet that communicate with each other. The second air inlet 431 communicates with the external environment, and the second air outlet communicates with the air duct main body 42. By providing the reinforced air duct 43, the air in the external environment is directly introduced into the air duct main body 42, and together with the basic air duct 46, the air flow is introduced. The work of both air ducts can make the air flow contact the fins 22 to take away the heat generated by the parts to be cooled, further enhancing the heat dissipation capacity of the air duct main body.

[0040] Specifically, the blower 12 is above the air collecting cavity 52 and sends air into the air collecting cavity 52. The funnel-shaped air collecting cavity 52 converges the air flow and then enters the basic air duct 46 through the first air inlet 41 on the air duct, and then enters the air duct main body 42 for rapid circulation. The air flow contacts the fins 22 to take away the heat generated by the component to be cooled 3. There is a fan 432 and a driving motor in the strengthening air duct 43. When the fan 432 operates, it introduces the external air flow into the strengthening air duct 43 for rapid circulation in the air duct main body 42. The operation of both air ducts enables the air flow to contact the fins 22 to take away the heat generated by the component to be cooled 3, solving the technical problem of quickly taking away the heat of the heat-generating components on the outdoor unit main board when the components in the prior art generate too much heat.

[0041] In the air conditioner outdoor unit of this embodiment, refer to Figure 3 , the air duct 4 includes an air duct switch 44. The air duct switch 44 includes a wind deflector 441 inserted in the strengthening air duct 43. The wind deflector 441 is used to block the circulation of the air flow in the strengthening air duct 43. The wind deflector 441 is movably arranged. The air duct switch 44 is located between the strengthening air duct 43 and the second air outlet. Through the above settings, the movement of the wind deflector 441 can be controlled according to actual needs, so as to open or close the strengthening air duct 43. When the strengthening air duct 43 is opened, the strengthening air duct 43 and the basic air duct 46 introduce air flow into the air duct main body 42 together. When the strengthening air duct 43 is closed, only the basic air duct 46 introduces air flow into the air duct main body 42.

[0042] It should be noted that the layout structure between each air duct can be adjusted according to the internal space layout of the air conditioner indoor unit. For example, in some embodiments, the basic air duct 46 is vertically connected to the air duct main body 42, the strengthening air duct 43 is parallel to the basic air duct 46, and the wind deflector 441 is located between the strengthening air duct 43 and the air duct main body 42.

[0043] In the air conditioner outdoor unit of this embodiment, refer to Figure 2 , the air conditioner outdoor unit includes: a temperature detector for detecting the ambient temperature; a controller, which is respectively signal-connected to the temperature detector and the air duct switch 44, and the controller controls the movement of the wind deflector 441 according to the ambient temperature.

[0044] In some embodiments, the air conditioner outdoor unit further includes a current detection device. By detecting the working current of the component to be cooled, the load condition of the component to be cooled can be judged. The ambient temperature and the working current can be used as joint judgment conditions to judge whether it is necessary to open the strengthening air duct 43. The air duct structure in this embodiment can be adjusted in combination with the load condition and working condition of the component to be cooled, and when the load of the component to be cooled is too large, the heat dissipation capacity is increased.

[0045] Specifically, when the detected ambient temperature is low and the working current of the component to be cooled is small, the enhanced air duct 43 is closed. At this time, only the basic air duct 46 works. When it is detected that the ambient temperature is high and the working current of the component to be cooled 3 is large, the temperature of the component to be cooled 3 is high at this time and the heat dissipation intensity needs to be increased. At this time, the enhanced air duct 43 is opened, and the basic air duct 46 and the enhanced air duct 43 work together to increase the heat dissipation capacity of the air duct main body 42.

[0046] In the outdoor unit of the air conditioner in this embodiment, refer to Figure 3 、 Figure 7 On the wind deflector 441, a rack 442 is provided. The air duct switch 44 includes: a gear 443, and the gear 443 meshes with the rack 442; a control motor 444, and the control motor 444 is used to control the rotation of the gear 443 to drive the movement of the wind deflector 441. Through the above settings, by controlling the rotation of the gear 443, the wind deflector 441 can be driven to move, so as to open or close the enhanced air duct 43.

[0047] Specifically, a limiting groove for the movement of the wind deflector 441 is provided on the side wall in the air duct. The width of the limiting groove is adapted to the wind deflector 441. On the one hand, the movement of the wind deflector 441 can be restricted through the limiting groove, and on the other hand, the leakage of the air flow in the air duct can be minimized as much as possible.

[0048] In the outdoor unit of the air conditioner in this embodiment, refer to Figure 3 The enhanced air duct 43 includes: a fan 432, and the fan 432 is located at the second air inlet 431; a driving motor, and the driving motor is signal-connected to the controller. The driving motor is used to drive the fan 432 to rotate to introduce the air flow into the enhanced air duct 43. Through the above settings, the air flow in the external environment is introduced into the enhanced air duct 43 through the fan 432 to increase the heat dissipation capacity of the air duct main body 42.

[0049] In the outdoor unit of the air conditioner in this embodiment, refer to Figure 4 On the side wall of the air duct main body 42, an installation groove 421 is provided. The radiator 2 includes installation buckles 21 corresponding to the installation groove 421, and the installation buckles 21 are detachably embedded in the installation groove 421; wherein, both the installation groove 421 and the installation buckles 21 include a plurality of them, and the plurality of installation grooves 421 and the plurality of installation buckles 21 are arranged in one-to-one correspondence. Specifically, the radiator 2 and the air duct main body 42 can be detachably connected to realize the fixation of the air duct main body 42.

[0050] In the outdoor unit of the air conditioner in this embodiment, refer to Figure 8, the radiator 2 includes a plurality of fins 22 which are arranged at intervals, and the extending direction of the plurality of fins 22 is consistent with the extending direction of the air duct main body 42. By providing the fins 22, the air flow entering the air duct main body 42 can enter the gaps between the fins 22, increasing the contact area between the radiator and the air, and improving the heat dissipation speed and efficiency.

[0051] Specifically, a card slot for placing the refrigerant pipe is provided on the radiator 2. On the basis of the traditional refrigerant pipe cooling structure, the radiator in this embodiment is provided with an air duct structure, which can quickly take away the heat of the heating elements on the outdoor unit main board when the components generate too much heat, and its heat dissipation effect is significantly better than that of the traditional radiator.

[0052] In the air conditioner outdoor unit of this embodiment, refer to Figure 4 , the air duct 4 includes a wind guide cover 45. The air inlet 451 of the wind guide cover 45 is connected to the air collecting outlet 53, and the air outlet 452 of the wind guide cover 45 is connected to the first air inlet 41; wherein, the extending direction of the air inlet 451 is perpendicular to the extending direction of the air outlet 452. Through the above settings, the direction of the air flow entering the basic air duct 46 is changed, so as to guide the air flow to the component to be cooled 3, and the air guiding direction of the wind guide cover 45 can be adaptively adjusted according to the internal structure of the air conditioner outdoor unit.

[0053] In some embodiments, liquid cooling and air cooling can be combined. By adding fins to the liquid-cooled radiator to make it have the function of air cooling, the heat dissipation requirements of the outdoor unit main board can also be met.

[0054] The following introduces an optional embodiment of the present invention:

[0055] In the air conditioner outdoor unit of this embodiment, the air blown out by the fan 12 can be blown into the radiator 2 through the air duct. The temperature of the air from the fan 12 is lower than the temperature of the radiator 2, which can quickly take away the temperature of the radiator 2. The original radiator is replaced with a radiator 2 with fins 22 to increase the contact area between the radiator and the air.

[0056] A funnel-shaped air collecting cavity 52 is designed on the grille. The large end of the funnel-shaped air collecting cavity 52 is close to the fan 12 side, and the small end is close to the grille 6 side. The gas converges from the large end to the small end position of the funnel-shaped air collecting cavity 52, and the small end is arranged directly below the air outlet 452. The air pressure at the small end in the funnel-shaped air collecting cavity 52 is greater than the air pressure at the air outlet 452, forming an obvious pressure difference, and the air flow flows out from the pressure higher funnel-shaped air collecting cavity 52 through the air outlet 452.

[0057] The air duct is composed of a second air inlet 431, a reinforced air duct 43, a drive motor, a fan, an air guide inlet 451, a basic air duct 46, a wind deflector 441, a control motor 444, gears, and an air duct main body 42. The external environment temperature is transmitted to the external machine main board through the external machine environment temperature sensor, and instructions are sent to the drive motor and the control motor 444 of the air duct system by combining the environmental temperature and the operating current of the components. In the early stage, the operating programs of the drive motor and the control motor 444 are designed through temperature rise experiment data: when the detected external environment temperature is low and the operating current of the components is small, the drive motor does not work, and the wind deflector 441 with a rack is adjusted through the control motor 444 and the connected gears to close the reinforced air duct 43. At this time, only the reinforced air duct 43 of the air duct system works, and the basic air duct 46 does not work. The non-operation of the drive motor can reduce energy consumption and the noise impact of the drive motor. There is an air guide inlet 451 on the air duct connected to the grille air guide outlet 452. A part of the air flow generated by the fan 12 is concentrated by the funnel-shaped air collecting cavity 52 and then enters the air duct main body 42 through the air guide outlet 452, so that there is obvious air flow in the air duct main body 42. The air duct main body 42 is designed with a card slot to fix the air duct main body 42 on the finned radiator; when the detected external environment temperature is high and the operating current of the components is large, the wind deflector 441 is adjusted through the control motor 444 and the connected gears to open the reinforced air duct 43. At this time, both the reinforced air duct 43 and the basic air duct 46 work, and the drive motor runs to drive the fan 432 to rotate, introducing the air flow into the reinforced air duct 43 to enhance the heat dissipation capacity. The operating current of the electronic components increases with the increase of the fan speed and the compressor operating frequency, and the noise of the drive motor is covered by the louder fan sound and compressor sound.

[0058] The fan 12 is above the funnel-shaped air collecting cavity 52, sending air into the funnel-shaped air collecting cavity 52. The airflow is converged by the funnel-shaped air collecting groove into the air guide outlet 452 and then enters the air duct main body 42 through the air guide inlet 451, and then quickly circulates in the air duct main body 42. The gas contacts the fins to take away the heat generated by the components. There is a fan 432 and a drive motor in the basic air duct 46. When the fan 432 runs, the external air flow is introduced into the reinforced air duct 43 and quickly circulates in the air duct main body 42. The operation of both air ducts can make the gas contact the fins 22 to take away the heat generated by the components, realizing the rapid removal of the heat of the heating elements on the external machine main board when the components generate excessive heat.
