Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0048] Specifically, the air conditioner outdoor unit provided in the embodiment of the present application is provided with a radiator 221 and a mounting plate 21 to form a coolant channel 23, and the coolant channel 23 is connected to the coolant inlet 11, and a part of the radiator 221 extends into the coolant channel 23, so that the coolant flowing from the coolant inlet 11 into the coolant channel 23 can cool the radiator 221, thereby accelerating the heat dissipation speed of the radiator 221 to the main control board 22, and ensuring the normal operation of the main control board 22 and the air conditioner. In the air conditioner outdoor unit of the embodiment of the present application, the electric control module 2 adopts a coolant heat dissipation method, so the heat dissipation efficiency of the electric control module 2 is higher than that of the traditional air cooling heat dissipation method, and avoids the condensation problem that may occur in the electric control module in the refrigerant heat dissipation method, and has a good heat dissipation effect.

[0049] In the embodiment of the present application, the coolant is introduced to dissipate heat and cool the heat by flowing through the radiator 221 and the mounting plate 21 to form the coolant channel 23, and the structural characteristics of the electric control module 2 are cleverly utilized, so that the internal space of the housing 1 of the air conditioner outdoor unit does not need to be additionally occupied, and a complex heat dissipation device does not need to be specially arranged, and the heat dissipation efficiency of the coolant is high. Therefore, the overall structural arrangement of the air conditioner outdoor unit in the embodiment of the present application is more compact and the structural design is simple.

[0050] In an exemplary embodiment, Figure 8 and Fig. 9 As shown, the mounting plate 21 has a U-shaped groove 211 , a portion of the heat sink 221 extends from an opening of the U-shaped groove 211 into the U-shaped groove 211 , and the heat sink 221 closes the opening of the U-shaped groove 211 to form a coolant channel 23 .

[0051] Specifically, the radiator 221 closes the opening of the U-shaped groove 211, so that the radiator 221 and the U-shaped groove 211 are combined to form a coolant channel 23, and both ends of the coolant channel 23 are connected to form a liquid inlet and a liquid outlet of the coolant channel 23. Part of the radiator 221 extends into the U-shaped groove 211, so that the coolant flowing through the coolant channel 23 can cool the radiator 221 and the main control board 22.

[0052] In an exemplary embodiment, Figure 8 and Fig. 9 As shown, the radiator 221 includes a heat dissipation substrate 2211 and a plurality of heat dissipation fins 2212 mounted on a board surface of the heat dissipation substrate 2211. The heat dissipation substrate 2211 is fixedly connected to the main control board 22. The heat dissipation substrate 2211 closes the opening of the U-shaped groove 211 of the mounting plate 21. The plurality of heat dissipation fins 2212 are all extended into the U-shaped groove 211, and a liquid gap 2213 for the coolant to pass through is formed between adjacent heat dissipation fins 2212. The heat dissipation substrate 2211 and the heat dissipation fins 2212 can be made of a heat conductive material with good heat conductivity, such as: the heat dissipation substrate 2211 and the heat dissipation fins 2212 can be made of metal materials (such as: aluminum, etc.) or other materials.

[0053] Specifically, the radiator 221 is configured to include a heat dissipation substrate 2211 and a plurality of heat dissipation fins 2212, and the plurality of heat dissipation fins 2212 are all mounted on one surface of the heat dissipation substrate 2211, and the main control board 22 can be mounted on the other surface of the heat dissipation substrate 2211, and can directly contact and exchange heat with the heat dissipation substrate 2211. The heat dissipation substrate 2211 can close the opening of the U-shaped groove 211 to form a coolant channel 23, and the plurality of heat dissipation fins 2212 extend from the opening of the U-shaped groove 211 into the U-shaped groove 211. The coolant flowing through the coolant channel 23 can exchange heat with the heat dissipation substrate 2211 on the one hand, and can exchange heat with the heat dissipation fins 2212 on the other hand, so that the heat dissipation area and heat exchange area of ​​the radiator 221 are larger, and the heat dissipation and heat exchange efficiency can be improved.

[0054] In an exemplary embodiment, Figure 8As shown, the mounting plate 21 includes a first sub-mounting plate 212, a second sub-mounting plate 213 and an L-shaped bending portion 214. The first sub-mounting plate 212 and the second sub-mounting plate 213 are connected in an L shape. The L-shaped bending portion 214 is located between the first sub-mounting plate 212 and the second sub-mounting plate 213 and connected to the second sub-mounting plate 213. The L-shaped bending portion 214 cooperates with the second sub-mounting plate 213 to form a U-shaped groove 211, and the opening of the U-shaped groove 211 faces the first sub-mounting plate 212. There is a gap between the opening of the U-shaped groove 211 and the first sub-mounting plate 212. The main control board 22 can be installed in the gap between the opening of the U-shaped groove 211 and the first sub-mounting plate 212 and close to the first sub-mounting plate 212. The heat sink 221 can be close to the U-shaped groove 211. The main control board 22 can be fixedly connected to the first sub-mounting plate 212, such as: can be fixedly connected to the first sub-mounting plate 212 by a fastener (such as a fastening screw).

[0055] Specifically, an L-shaped bending portion 214 is provided to cooperate with the second sub-mounting plate 213 to form a U-shaped groove 211, so that the first sub-mounting plate 212 and the second sub-mounting plate 213 both have a protective and accommodating function for the U-shaped groove 211, and further have a protective function for the radiator 221 and the main control board 22 installed at the opening of the U-shaped groove 211.

[0056] Compared with providing a closed box to install the main control board 22 and the radiator 221, the mounting plate 21 of the embodiment of the present application has a simple structure and is convenient for removing the main control board 22 and the radiator 221 from the mounting plate 21 for maintenance.

[0057] In an exemplary embodiment, Figure 1 , Figure 3 , Figure 6-Figure 8 As shown, the housing 1 is provided with a mounting cavity 152, the mounting cavity 152 has a first opening facing one side (such as the left side or the right side), the first sub-mounting plate 212 blocks the first opening of the mounting cavity 152, and the second sub-mounting plate 213 is located in the mounting cavity 152. The mounting plate 21 can be fixedly connected to the housing 1 by fasteners (such as fastening screws), such as: the first sub-mounting plate 212 can be fixedly connected to the housing 1 by fasteners (such as fastening screws).

[0058] Specifically, the installation cavity 152 may have a first opening facing the left side or the right side, and the first opening 152 may pass through the left side or the right side of the housing 1. During the installation of the electric control module 2, after the main control board 22 with the radiator 221 fixed thereto is installed on the installation plate 21, the installation plate 21 together with the main control board 22 is installed into the installation cavity 152 of the housing 1, as shown in FIG. Figure 1As shown, the first sub-mounting plate 212 of the mounting plate 21 can cover the first opening of the mounting cavity 152, so that the first sub-mounting plate 212 is exposed, so that the first sub-mounting plate 212 can be fixedly connected to the housing 1 by fasteners (such as fastening screws), or the fasteners (such as fastening screws) can be removed to disassemble the electronic control module 2.

[0059] In an exemplary embodiment, Figure 1 , Figure 2 , Figure 6-Figure 8 As shown, an air outlet 13 is provided on one side of the housing 1 close to the second sub-mounting plate 213 , and a detachable grille 14 is installed at the air outlet 13 .

[0060] The installation cavity 152 has a second opening facing the air outlet 13, for example, the front side of the installation cavity 152 may be provided with a second opening, the air outlet 13 is located at the front side of the housing 1, and the installation cavity 152 is connected with the air outlet 13 of the housing 1 through the second opening. The second sub-mounting plate 213 is provided with a hand grip 2131, the hand grip 2131 is located on a side of the L-shaped bending portion 214 away from the first sub-mounting plate 212, and the hand grip 2131 is configured to be able to be operated through the air outlet 13 to remove the electric control module 2 from the first opening of the installation cavity 152.

[0061] Specifically, the air outlet 13 is used for discharging air from the outdoor unit of the air conditioner. A removable grille 14 is installed at the air outlet 13 to prevent dust, leaves and other debris from entering the housing 1 through the air outlet 13. When debris accumulates at the grille 14, it can be removed and cleared.

[0062] Furthermore, after the operator removes the grille 14 and the fasteners fixing the mounting plate 21 and the housing 1, the operator can extend his hand into the mounting cavity 152 through the air outlet 13 and the second opening of the mounting cavity 152 to hold the hand grip 2131, so as to push the mounting plate 21 and the main control board 22 out of the first opening of the mounting cavity 152, thereby realizing the removal of the electric control module 2. Therefore, the structural design of the first opening and the second opening of the mounting cavity 152, the hand grip 2131, the air outlet 13 and the grille 14 facilitates the operator to remove and install the electric control module 2.

[0063] In an exemplary embodiment, Figure 1 , Figure 6 and Figure 10-11 As shown, the outdoor unit of the air conditioner also includes an outdoor heat exchanger 3, and the liquid outlet 231 of the cooling liquid channel 23 faces downward and is located above the outdoor heat exchanger 3, so that the cooling liquid flowing out of the cooling liquid channel 23 can drip onto the outdoor heat exchanger 3.

[0064] Specifically, the coolant can enter the coolant channel 23 through the coolant inlet 11, and can absorb the heat of the radiator 221 to evaporate in the coolant channel 23. The coolant that has not completely evaporated in the coolant channel 23 can drip from the liquid outlet 231 onto the outdoor heat exchanger 3, and the coolant can absorb the heat of the outdoor heat exchanger 3 (which can be used as a condenser) to further evaporate. The coolant 3 absorbs the heat of the outdoor heat exchanger 3, which helps to improve the heat exchange efficiency of the outdoor heat exchanger 3, and further helps to improve the overall cooling effect of the air conditioner. Fig.10 and Fig.11 The direction indicated by the arrow is the flow direction of the coolant.

[0065] In an exemplary embodiment, Figure 6 and Fig.10 As shown, the outdoor unit of the air conditioner further includes a centrifugal fan 4 , which is located above the outdoor heat exchanger 3 .

[0066] Specifically, Figure 6 As shown, a centrifugal fan 4 is arranged above the outdoor heat exchanger 3. Under the action of the centrifugal fan 4, the air can flow upward toward the centrifugal fan 4 after heat exchange with the outdoor heat exchanger 3, and be discharged to the outside of the casing 1 from the air outlet 13 on the front side of the casing 1.

[0067] In the prior art, axial flow fans are generally used in air conditioner outdoor units, and the axial flow fans are generally located in front of the outdoor heat exchanger. Considering factors such as heat dissipation efficiency and noise, the size of the air duct in the air conditioner outdoor unit along the length direction of the casing (roughly equal to the size of the axial flow fan along the length direction of the casing) has always accounted for about 2 / 3 of the length of the casing, which restricts the miniaturization of the air conditioner outdoor unit. In the embodiment of the present application, the centrifugal fan 4 is used for the air conditioner outdoor unit, and the centrifugal fan 4 is placed above the outdoor heat exchanger 3, so that the structure of the air conditioner indoor unit is compact, the length of the air conditioner outdoor unit with the same cooling capacity can be shortened by 2 / 3, and the overall volume of the air conditioner indoor unit can be reduced by 1 / 3, thereby realizing the miniaturization of the air conditioner outdoor unit, increasing the packaging volume of the product, and reducing the installation space of the air conditioner indoor unit.

[0068] In an exemplary embodiment, Figure 1 , Figure 3-Figure 4 , Figure 6 and Figure 7 As shown, the centrifugal fan 4 includes a motor 41 and a centrifugal fan wheel 42, and the motor 41 is connected to the centrifugal fan wheel 42. The casing 1 includes an upper casing 15, which is arranged above the outdoor heat exchanger 3, and a volute 151 is arranged in the upper casing 15, and the centrifugal fan wheel 42 is installed in the volute 151.

[0069] Specifically, the motor 41 is used to drive the centrifugal fan wheel 42 to rotate, and the air after heat exchange with the outdoor heat exchanger 3 can be sucked into the centrifugal fan wheel 42, enter the volute 151, and finally discharge the hot air through the air outlet 13. Compared with the axial flow fan, the centrifugal fan 4 has the advantages of high wind pressure, large air volume and compact structure. The outdoor unit of the air conditioner in the embodiment of the present application adopts the centrifugal fan 4 for heat exchange, which can reduce the volume of the outdoor unit of the air conditioner.

[0070] In an exemplary embodiment, Figure 1 and Figure 6 As shown, the casing 1 also includes a chassis 16, a panel 17 and a top cover plate 18. The outdoor heat exchanger 3 is fixed on the chassis 16, and the outdoor heat exchanger 3 is in a U-shape with the opening facing forward. The panel 17 is fixed to the front side of the outdoor heat exchanger 3 and the upper casing 15, and blocks the opening of the outdoor heat exchanger 3. A first air duct 31 is formed in the outdoor heat exchanger 3.

[0071] like Figure 6 and Figure 7 As shown, the air inlet port 154 of the volute 151 faces downward and the air outlet port 155 faces forward, and the air inlet port 154 of the volute 151 is connected to the first air duct 31, the panel 17 is provided with an air outlet 13, the air outlet 13 is connected to the air outlet port 155 of the volute 151, and the top cover plate 18 is fixed above the upper casing 15.

[0072] Specifically, the outdoor heat exchanger 3 is configured to be in a U-shape with its opening facing forward, so that the heat exchange area of ​​the outdoor heat exchanger 3 is larger, and this structural design can increase the size of the outdoor heat exchanger 3 while reducing the volume of the air conditioner outdoor unit, thereby improving the heat exchange efficiency.

[0073] The air inlet port 154 at the lower end of the volute 151 is arranged to communicate with the first air duct 31 in the outdoor heat exchanger 3, and the outdoor heat exchanger 3 can be exposed, so that under the action of the centrifugal fan 4, the outdoor air can flow through the outdoor heat exchanger 3 and enter the first air duct 31 formed in the outdoor heat exchanger 3, and then enter the volute 151 from the air inlet port 154. The air outlet 13 is arranged to communicate with the air outlet port 155 on the front side of the volute 151, so that the air in the volute 151 is discharged to the outside through the air outlet port 155 and the air outlet 13.

[0074] In an exemplary embodiment, Figure 6 and Figure 7 As shown, the upper housing 15 is provided with an installation cavity 152, the installation cavity 152 is located outside the volute 151, and the electric control module 2 is installed in the installation cavity 152 and fixedly connected to the upper housing 15. Among them, the first sub-mounting plate 212 of the mounting plate 21 of the electric control module 2 can be detachably connected to the upper housing 15 through fasteners (such as fastening screws), so as to disassemble and repair the electric control module 2.

[0075] Specifically, the installation cavity 152 for installing the electric control module 2 is arranged in the upper housing 15 above the outdoor heat exchanger 3, so that the cooling liquid channel 23 formed by the radiator 221 of the electric control module 2 and the installation plate 21 can be located above the outdoor heat exchanger 3, so that the cooling liquid that is not completely evaporated in the cooling liquid channel 23 drips onto the outdoor heat exchanger 3 and absorbs the heat of the outdoor heat exchanger 3 to evaporate. Among them, the bottom wall of the installation cavity 152 can be provided with a connecting hole, so that the cooling liquid in the cooling liquid channel 23 can drip onto the outdoor heat exchanger 3 after passing through the liquid outlet 231 and the connecting hole.

[0076] The installation cavity 152 for installing the electric control module 2 is located outside the volute 151 so that the electric control module 2 does not affect the air inlet and outlet of the volute 151, thereby avoiding increasing wind resistance.

[0077] In an exemplary embodiment, Figure 6 and Figure 7 As shown, the upper end of the installation cavity 152 has a third opening that passes through it, and the electric control module 2 is configured to be installed into the installation cavity 152 from the third opening of the installation cavity 152 , and the electric control module 2 is configured to be disassembled from the third opening of the installation cavity 152 .

[0078] The top cover plate 18 of the housing 1 can cover the third opening at the upper end of the mounting cavity 152 and press the electric control module 2 to enhance the fixing effect of the electric control module 2. The coolant inlet 11 can be arranged on the top cover plate 18, so that the coolant inlet 11 can be higher than the coolant channel 23 formed by the radiator 221 of the electric control module 2 and the mounting plate 21, so that the coolant entering from the liquid inlet 11 can flow into the coolant channel 23 under the action of gravity.

[0079] The electric control module 2 of the embodiment of the present application can be disassembled from the first opening on one side of the installation cavity 152 , or can be disassembled from the third opening on the upper end of the installation cavity 152 after the top cover plate 18 is removed.

[0080] In an exemplary embodiment, Figure 6 and Figure 7 As shown, the inner wall surface of the mounting cavity 152 is provided with a sliding limit portion 156 extending in the vertical direction; the electric control module 2 is provided with a limit matching portion, such as the second sub-mounting plate 213 of the mounting plate 21 of the electric control module 2 can be provided with a limit matching portion, and the limit matching portion is configured to be able to slide along the sliding limit portion 156 and cooperate with the sliding limit portion 156 for limiting.

[0081] The inner wall surface of the installation cavity 152 and the electric control module 2 are respectively provided with a sliding limit portion 156 and a limit matching portion. When the electric control module 2 is installed from the third opening at the upper end of the installation cavity 152, the limit matching portion can be made to slide downward along the sliding limit portion 156.
