[0009] An electrical box, which includes a box body and a box cover;

[0010] The partition has an upward-facing support position, and the electrical box is installed in the support position. Part of the electrical box extends into the fan compartment, and another part of the electrical box extends into the compressor compartment.

[0011] In some embodiments of this application, a support portion is formed on the support position, the support portion is formed on the bottom of the support position and / or at least one side wall of the support position, and the electrical box is mounted on the support portion.

[0012] The electrical box is connected to the support within the support position, which helps to improve the stability of the connection.

[0013] In some embodiments of this application, the support portion includes a support base plate and support side plates. The support base plate is a horizontal bend formed at the bottom of the support position, and the support side plates are bends formed on both sides of the support position. Mounting holes are formed on the support base plate, the electrical box is fixed in the mounting holes, and the side wall of the electrical box is in contact with the corresponding support side plate.

[0015] The side wall of the electrical box is in contact with the supporting side plate, which increases the contact area between the side wall of the electrical box and the partition, thereby improving the stability of the electrical box.

[0016] In some embodiments of this application, the bottom of the electrical box is formed with a positioning partition that is adapted to the shape of the partition member, and the positioning partition is connected to the side of the partition member near the fan hopper.

[0017] The positioning partition is a raised edge extending downward at the bottom of the electrical box. The positioning partition extends along the side of the partition member near the fan compartment to improve the sealing effect between the fan compartment and the compressor compartment, and to prevent rainwater or insects in the fan compartment from entering the compressor compartment from the bottom of the electrical box and affecting the working parts in the compressor compartment.

[0018] In some embodiments of this application, at least one side of the electrical box is further provided with a mounting groove, the corresponding side of the partition is connected to the mounting groove, and the supporting side plate is in contact with the inner wall of the mounting groove.

[0019] The two sides of the support on the partition are inserted into the mounting groove, which helps to improve the connection and sealing between the two sides of the electrical box and the partition, further isolates the fan compartment and the compressor compartment, and improves the waterproof and insect-proof effect.

[0020] In some embodiments of this application, a fastening hole is provided at the top of the mounting groove, and a horizontal fixing bend is formed at the top of the corresponding side of the partition member. A fixing hole corresponding to the fastening hole is formed on the horizontal fixing bend, and the fixing hole is connected to the corresponding fastening hole by a fastener.

[0024] In some embodiments of this application, an installation cavity is formed inside the box body and the box cover, and a water-blocking protrusion is provided at the bottom of the installation cavity. The water-blocking protrusion is used to reduce water from entering the installation cavity from the fan compartment.

[0025] During rainy weather, as the wind turbines inside the condensate rotate, some rainwater is thrown into the electrical box. The design of the water-blocking protrusion can reduce the amount of rainwater and moisture entering the electrical box.

[0026] In some embodiments of this application, an overflow hole is provided at the bottom of the mounting cavity. The overflow hole is connected to the fan housing. A waterproof cover is provided on the top of the overflow hole. The waterproof cover has an opening on the side near the side wall of the housing to reduce the amount of water in the fan housing entering the mounting cavity from the overflow hole.

[0027] The overflow hole is connected to the fan compartment and is used to drain water from the electrical box.

[0028] The waterproof cover is placed above the overflow hole to reduce the amount of water entering the installation cavity from the fan compartment through the overflow hole.

[0029] In some embodiments of this application, a heat exchanger is further provided inside the outer shell, an end plate is provided at the end of the heat exchanger, and a continuous overlapping bend is provided on one side of the partition member from top to bottom, the overlapping bend being detachably connected to the end plate.

[0030] The overlapping bends on the partition plate and the end plate make integral surface contact, which ensures good connection stability and strong sealing. This avoids the risk of water vapor, insects, etc. in the fan compartment entering the compressor compartment through the connection gap between the partition plate and the end plate due to poor contact during long-term operation.

In addition, examples of various specific processes and materials are provided in this invention, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0061] In this application, the air conditioner performs a refrigeration cycle by using a compressor, condenser, expansion valve, and evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation to cool or heat an indoor space.

[0062] Low-temperature, low-pressure refrigerant enters the compressor, which compresses it into a high-temperature, high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0063] The expansion valve expands the high-temperature, high-pressure liquid refrigerant that condenses in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the expanded refrigerant in the expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the air conditioner regulates the temperature of the indoor space.

[0064] The outdoor unit of an air conditioner refers to the part of the refrigeration cycle that includes the compressor and the outdoor heat exchanger. The indoor unit of an air conditioner includes the indoor heat exchanger, and an expansion valve can be provided in either the indoor or outdoor unit.

[0065] The indoor and outdoor heat exchangers function as either condensers or evaporators. When the indoor heat exchanger is used as a condenser, the air conditioner functions as a heater in heating mode; when the indoor heat exchanger is used as an evaporator, the air conditioner functions as a cooler in cooling mode.

[0066] refer to Figures 1-3 This utility model proposes an outdoor unit for an air conditioner, which includes an outer shell 100, a partition 300, and an electrical box 200.

[0067] The outer shell 100 includes a top plate 110, a bottom plate, and peripheral side plates, which together form an inner cavity.

[0068] The partition 300 is vertically installed in the inner cavity, dividing the inner cavity into a fan compartment and a compressor compartment.

[0069] The fan compartment contains the fan, and the compressor compartment contains the compressor and other working components.

[0070] An air inlet and an air outlet are formed on the outer casing 100. After the fan is started, the airflow is input into the fan compartment from the air inlet under the action of the fan. After exchanging heat with the outdoor heat exchanger installed in the outer casing 100, the airflow is output to the outside from the air outlet.

[0071] Therefore, since the wind turbine compartment is connected to the outside world, rainwater can enter the wind turbine components during rainy weather. As the fan blades rotate, the rainwater splashes in all directions. In addition, there is also the problem of foreign objects such as mosquitoes entering the wind turbine compartment.

[0072] The compressor compartment is isolated from the fan compartment by a partition 300 to prevent rainwater, insects, etc. from entering the compressor compartment from the fan compartment.

[0073] To avoid problems such as large installation errors, large gaps, and poor sealing caused by installing the electrical box 200 on different structural components (e.g., on the partition 300 and the end plate 400 of the heat exchanger).

[0074] The partition 300 is integrally stamped to ensure the accuracy of the fixed dimensions and the sealing performance. The electrical box 200 in this application is connected and fixed only through the partition 300, which improves the assembly accuracy and reduces the assembly error.

[0075] Specifically, the electrical box 200 includes a box body 220 and a box cover 210. The partition 300 has an upward-opening U-shaped support position 310. The electrical box 200 is installed in the support position 310. Part of the electrical box 200 extends into the fan compartment, and another part of the electrical box 200 extends into the compressor compartment.

[0076] In other words, combining Figure 3 , Figure 5 The middle position of the partition 300 is supported on the partition 300. The first end 201 of the electrical box 200 extends into the fan compartment and the second end 202 extends into the compressor compartment, so as to make full use of the internal cavity space of the outer shell 100.

[0077] In some embodiments of this application, a support portion is formed on the support position 310, the support portion being formed on the bottom of the support position 310 and / or at least one side wall of the support position 310, and the electrical box 200 is mounted on the support portion.

[0078] The electrical box 200 is connected to the support part within the support position 310, which helps to increase the contact area between the electrical box 200 and the partition 300, and helps to improve the stability of the connection.

[0079] refer to Figure 4 In some embodiments of this application, the support includes a support base plate 311 and a support side plate. The support base plate 311 is a horizontal bend formed at the bottom of the support position 310. The support base plate 311 can be a continuous bend formed at the bottom of the support position 310 or it can be segmented.

[0080] The support base plate 311 provides stable support for the bottom of the electrical box 200, preventing the first end 201 and the second end 202 of the electrical box 200 from shaking.

[0081] The electrical box 200 is fixed to the junction of the top of the fan compartment and the compressor compartment via the support base plate 311, with one half extending into the compressor compartment and the other half extending into the compressor compartment.

[0082] The bending direction of the support base plate 311 can be towards the wind turbine nacelle or it can be designed to be bent towards the compressor nacelle.

[0083] Mounting holes are formed on the support base plate 311, and the electrical box 200 is fixed on the mounting holes. The number of mounting holes is designed according to actual needs, and can be set to at least two to improve the stability of the connection.

[0084] The supporting side plate is formed by bends on both sides of the supporting position 310; the side wall of the electrical box 200 is in contact with the corresponding supporting side plate.

[0085] Specifically, a first support side plate 312 is formed on one side of the support position 310, bending towards the wind turbine nacelle or compressor nacelle, and a second support side plate 313 is formed on the other side of the support position 310, bending towards the wind turbine nacelle or compressor nacelle.

[0086] The bending directions of the first support side plate 312 and the second support side plate 313 can be the same or different.

[0087] The bending direction of the supporting side plate can be the same as or opposite to the bending direction of the supporting base plate 311.

[0088] The bottom of the electrical box 200 is fixedly connected to the support base plate 311, forming a surface contact with the support base plate 311, which helps to increase the connection area and thus improve the sealing effect of the connection.

[0089] The side wall of the electrical box 200 is in contact with the supporting side plate, which increases the contact area between the side wall of the electrical box 200 and the partition 300, thereby improving the stability of the electrical box 200.

[0090] refer to Figure 6 In some embodiments of this application, the bottom of the electrical box 200 is formed with a positioning partition 221 that is adapted to the shape of the partition 300, and the positioning partition 221 is connected to the side of the partition 300 near the fan compartment.

[0091] Specifically, the positioning partition 221 is a protruding edge extending downward from the bottom of the electrical box 200. The positioning partition 221 extends along the side of the partition 300 near the fan compartment to improve the sealing effect between the fan compartment and the compressor compartment, and to prevent rainwater or insects in the fan compartment from entering the compressor compartment from the bottom of the electrical box 200 and affecting the working parts in the compressor compartment.

[0092] In other words, when the electrical box 200 and the partition 300 are installed, the positioning partition 221 is in contact with the side of the partition 300 near the fan compartment to reduce the connection gap between the electrical box 200 and the partition 300.

[0093] Combination Figure 8 , Figure 9 In some embodiments of this application, at least one side of the electrical box 200 is provided with a mounting groove, the corresponding side of the partition 300 is connected to the mounting groove, and the support side plate is in contact with the inner wall of the mounting groove.

[0094] Specifically, a first mounting groove 222 and a second mounting groove 223 are respectively provided on the two side walls of the electrical box 200 body 220.

[0095] The positions of the first mounting groove 222 and the second mounting groove 223 correspond to the positions of the partition 300.

[0096] The two sides of the support position 310 on the partition 300 are inserted into the corresponding mounting groove, which helps to improve the connection and sealing between the two sides of the electrical box 200 and the partition 300, further isolates the fan compartment and the compressor compartment, and improves the waterproof and insect-proof effect.

[0097] In some embodiments of this application, a fastening hole is provided at the top of the mounting groove, and a horizontal fixing bend is formed at the top of the corresponding side of the partition 300. A fixing hole corresponding to the fastening hole is formed on the horizontal fixing bend, and the fixing hole is connected to the corresponding fastening hole by a fastener.

[0098] Specifically, the top of the first mounting groove 222 is provided with a first fastening hole 2221, the top of the second mounting groove 223 is provided with a second fastening hole 2231, and the fixing holes on the partition 300 are divided into a first fixing hole 331 and a second fixing hole 332.

[0099] The horizontal fixed bends on both sides of the partition 300 are detachably connected through fixing holes and corresponding fastening holes.

[0100] The horizontal fixed bend on the partition 300 is fixedly connected to the top of the mounting groove, which facilitates the operation of the operator. Together with the support base plate 311, the electrical box 200 is fixed on the partition 300.

[0101] The top height of the first mounting groove 222 and the second mounting groove 223 is flush with the top of the cover 210 of the electrical box 200. That is, after the cover 210 of the electrical box 200 is closed, the upper surface of the cover 210 of the electrical box 200 is flush with the top of the first mounting groove 222 and the second mounting groove 223. The top of the electrical box 200 is in contact with the top plate 110 of the outer shell 100 to ensure the sealing of the connection between the top plate 110 and the electrical box 200 and prevent the formation of ineffective wind fields.

[0102] The partition 300 and the electrical box 200 are fixed by three-sided contact, which fits tightly and can effectively prevent moisture from entering the compressor chamber through the contact surface.

[0103] This structure provides a more reliable fixation than a conventional electrical box 200, where one side contacts the partition 300 and the other side contacts the end plate 400. It also avoids the risk of moisture penetration caused by loosening and deformation of different components after long-term operation. The addition of a waterproof bonding surface between the electrical box 200 and the partition eliminates the need for insulation adhesive on the contact surface, saving materials and labor while preventing separation of the contact surface due to aging of the insulation cotton.

[0104] In other embodiments, in order to make the electrical box 200 compatible with more models of air conditioner outdoor units, multiple first mounting slots 222 and second mounting slots 223 are designed along the length direction of the electrical box 200, that is, from the first end 201 to the second end 202 of the electrical box 200, so as to meet the installation requirements of the partition plate 300 of different models of air conditioner outdoor units.

[0105] In other embodiments, in order to improve the structural strength of the partition member 300, a reinforcing molding 340 is also provided on the partition member 300.

[0106] In some embodiments of this application, reference is made to Figure 7 , Figure 8 A heat dissipation section 227 is provided on the first end 201 of the box 220 near the fan compartment. The heat dissipation section 227 is a heat dissipation grille used to dissipate the heat inside the electrical box 200 to the fan compartment.

[0107] The heat generated by the components inside the electrical box 200 during operation is output to the fan compartment through the heat dissipation grille to reduce the temperature of the electrical box 200.

[0108] In order to prevent rainwater in the fan compartment from splashing from the heat dissipation section 227 into the electrical box 200 and affecting the operation of the internal components, the heat dissipation section 227 is designed as a heat dissipation grille structure formed on the first end 201 of the box body 220. The heat dissipation vents on the heat dissipation grille are opened on the side wall of the heat dissipation grille to ensure ventilation and heat dissipation while reducing the passage of water vapor.

[0109] In some embodiments of this application, an installation cavity is formed inside the box body 220 and the box cover 210, and a water-blocking protrusion 224 is provided at the bottom of the installation cavity. The water-blocking protrusion 224 is used to reduce water from entering the installation cavity from the fan compartment.

[0110] The water-blocking flange 224 is designed as a continuous structure extending from one side to the opposite side at the bottom of the mounting cavity, which blocks rainwater from entering the electrical box 200 and prevents it from contacting the relevant components inside the electrical box 200.

[0111] During rainy weather, as the fan inside the fan compartment rotates, some rainwater will be thrown into the electrical box 200. The design of the water-blocking protrusion 224 can reduce the entry of rainwater and water vapor into the electrical box 200, thus protecting the circuit boards and other components installed inside the electrical box 200.

[0112] In some embodiments of this application, an overflow hole 225 is also provided at the bottom of the mounting cavity. The overflow hole 225 is designed between the heat dissipation part 227 and the water-blocking protrusion 224. That is, the overflow hole 225 is connected to the fan compartment and is used to drain the water in the electrical box 200.

[0113] In some other embodiments, the overflow hole 225 is covered with a waterproof cover 2251, which has an opening on the side near the side wall of the housing 220 to reduce the amount of water in the fan compartment entering the installation cavity from the overflow hole 225.

[0114] In some embodiments of this application, a heat exchanger is also provided inside the outer casing 100, and an end plate 400 is provided at the end of the heat exchanger. A continuous overlapping bend 320 is provided on one side of the partition 300 from top to bottom, and the overlapping bend 320 is detachably connected to the end plate 400.

[0115] The lap bend 320 has multiple connection holes spaced apart for detachable connection with the end plate 400.

[0116] The overlapping bend 320 on the partition plate 300 and the end plate 400 are in integral surface contact, which has good connection stability and strong sealing performance. This avoids the risk of water vapor, mosquitoes and other insects in the fan compartment entering the compressor compartment through the connection gap between the partition plate 300 and the end plate 400 due to poor contact during long-term operation, and improves the rainproof sealing effect.

[0117] refer to Figures 8-10 The box body 220 and the cover 210 in the electrical box 200 are detachably connected by a snap-fit ​​connection.

[0118] Specifically, a first latching part 226 is provided at the first end 201 of the box body 220, a second latching part 228 is provided at the second end 202 of the box body 220, a connecting outer edge is formed on the box cover 210, a first latching part 211 corresponding to the first latching part 226 is provided at the corresponding end of the connecting outer edge, and a second latching part 212 corresponding to the second latching part 228 is provided at the other end.

[0119] Specifically, the first latching part 226 is a protrusion formed on the first end 201 of the box body 220, and the first latching part 211 is a slot structure formed on the connecting outer edge. In the connected state, the first latching part 226 is latched into the corresponding first latching part 211.

[0120] The second latching part 228 is also a protrusion formed on the second end 202 of the box body 220. A guide slope is formed above the second latching part 228. After the first latching part 226 is connected to the first latching part 211, the second latching part 212 moves downward along the guide slope until it is connected to the second latching part 228, thus completing the connection and fixation between the box cover 210 and the box body 220.

[0121] Compared with the prior art, the advantages and positive effects of this utility model are:

[0122] The outdoor unit of the air conditioner involved in this application has a partition 300 that is integrally formed.
