Description

Technical Field

[0002] The air conditioner outdoor unit includes a shell, a partition is provided in the shell, and the partition divides the interior of the shell into a first chamber and a second chamber. A compressor is provided in the first chamber, and an outdoor heat exchange fan and an outdoor heat exchanger are provided in the second chamber. A refrigerant circuit is provided between the compressor and the outdoor heat exchanger. The outdoor heat exchange fan drives the outdoor air into the shell, and the air is blown outdoors after heat exchange with the outdoor heat exchanger.

[0003] The air conditioner's outdoor unit is equipped with a circuit board, which includes a power module. This power module is one of the main sources of heat on the circuit board. To ensure the normal operation and reliability of the circuit board, heat dissipation measures are required for the power module.

[0004] In some air conditioner outdoor units, a refrigerant radiator is used to dissipate heat from the power module. The refrigerant radiator includes a refrigerant tube and a heat dissipation adapter plate. A heat dissipation adapter plate is provided between the power module and the refrigerant tube. The heat dissipation adapter plate increases the contact area with the power module and promotes uniform heat conduction.

[0005] In the existing technology, the refrigerant pipe is connected to the heat dissipation adapter plate, the refrigerant pipe is welded to the refrigerant circuit, and then the electrical box and the circuit board are installed on the partition, and the heat dissipation adapter plate is connected to the electrical box and the circuit board. This will cause the assembly accuracy of the refrigerant radiator and the electrical box to deviate after the refrigerant pipe is welded, and the assembly efficiency cannot be improved.

[0006] On the other hand, in the prior art, the refrigerant radiator and the circuit board are pre-assembled together and then installed in the air conditioner outdoor unit. Since the refrigerant pipe needs to be welded, the high temperature during welding will affect the reliability of the circuit board.

[0007] In view of this, this application is filed. Utility Model Content

Based on the embodiments provided by the present disclosure, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present disclosure.

[0122] This embodiment provides an air conditioner outdoor unit. Figures 1-19 Describe the air conditioner outdoor unit.

[0123] The air conditioner outdoor unit 200 is a component of the air conditioner 1000 , wherein the air conditioner 1000 also includes the air conditioner indoor unit 100 .

[0124] See also Figures 1-4 The air conditioner 1000 may include an indoor air conditioner unit 100 and an outdoor air conditioner unit 200. The indoor air conditioner unit 100 is installed in an indoor space and the outdoor air conditioner unit 200 is installed in an outdoor space for exchanging heat with an outdoor environment.

[0125] The air-conditioning indoor unit may be a wall-mounted air-conditioning indoor unit or a floor-standing air-conditioning indoor unit. This application will be described using a wall-mounted air-conditioning indoor unit as an example.

[0126] Reference Figure 3The air conditioning indoor unit 100 includes a main body 300. The main body 300 has a bottom and a top. The height direction of the main body 300 is from the bottom to the top of the main body 300. The main body 300 also has a length direction, wherein the length direction of the main body 300 is from one side to the other side in the left-right direction of the main body 300. The main body 300 has a front side and a rear side that are oppositely arranged. The side of the main body 300 facing the user is the front side of the main body 300, and the front-to-back direction of the main body 300 is from the front side to the rear side of the main body 300.

[0127] The main body 300 may include a housing 3 , which is disposed in an indoor space. The housing 3 has a front side and a rear side that are opposite to each other, wherein a side of the housing 3 facing a user is the front side of the housing 3 .

[0128] The main body 300 may include a heat exchange air inlet 31, which is disposed on the top of the housing 3. During cooling or heating, indoor air may enter the interior of the housing 3 through the heat exchange air inlet 31.

[0129] The main body 300 may include a first cavity formed inside the housing 3 . The first cavity is communicated with the heat exchange air inlet 31 , and indoor air may enter the first cavity through the heat exchange air inlet 31 .

[0130] The main body 300 may include a heat exchange outlet 32 ​​disposed at the bottom of the housing 3. The first chamber is connected to the heat exchange inlet 31 and the heat exchange outlet 32. During cooling or heating, indoor air flows into the first chamber through the heat exchange inlet 31 and then into the room through the heat exchange outlet 32.

[0131] The main body 300 may include an indoor heat exchanger 1001 . The indoor heat exchanger 1001 is disposed in the first cavity. The indoor heat exchanger 1001 is configured to exchange heat with the indoor air entering the first cavity.

[0132] In some embodiments, the main body 300 may include a base, which is disposed in the first cavity and has a heat exchange air duct formed in the base.

[0133] In some embodiments, the main body 300 may include a heat exchange fan, which is disposed within the heat exchange duct, with the axial direction of the heat exchange fan being aligned with the longitudinal direction of the main body 300. The heat exchange fan operates to draw indoor air from the heat exchange inlet into the first chamber, then flows through the indoor heat exchanger 1001, through the heat exchange duct, and finally through the heat exchange outlet 32 ​​to the indoor room.

[0134] It can be arranged that the heat exchange fan is arranged on the leeward side of the indoor heat exchanger 1001 to reduce the resistance of the indoor heat exchanger 1001 to the air flow and increase the air intake into the room.

[0135] Reference Figure 2-Figure 5In some embodiments, the air-conditioning outdoor unit 200 is arranged in an outdoor space. The air-conditioning outdoor unit 200 includes a shell, which constitutes the appearance structure of the air-conditioning outdoor unit. The shell may include a front cover 213, which is located at the front of the shell. A accommodating cavity is provided in the shell 21.

[0136] In some embodiments, the air-conditioning outdoor unit may include a partition 22 , which is disposed in the accommodating cavity. The partition 22 divides the accommodating cavity into a first chamber and a second chamber, and the first chamber and the second chamber are disposed side by side.

[0137] In some embodiments, the first chamber and the second chamber may be in communication.

[0138] In some embodiments, the housing 21 may include an outdoor air inlet and an outdoor air outlet. The housing 21 has a front side and a rear side disposed opposite each other. The front side of the housing 21 is provided with an outdoor air outlet, and the rear side of the housing 21 is provided with an outdoor air inlet. The outdoor air inlet is connected to the outdoor space and the second chamber, and the outdoor air outlet is connected to the outdoor space and the second chamber. The housing 21 has a bottom and a top, and the height of the housing 21 is the distance from the bottom of the housing 21 to the top of the housing 21.

[0139] In some embodiments, the air-conditioning outdoor unit may include a compressor 201 , which is disposed in the first chamber and mounted at the bottom of the air-conditioning outdoor unit.

[0140] In some embodiments, the air conditioner outdoor unit may include an outdoor heat exchanger 202, and a refrigerant circuit is arranged between the compressor and the outdoor heat exchanger and the indoor heat exchanger. Refrigerant circulates in the indoor heat exchanger, the outdoor heat exchanger and the refrigerant circuit. The refrigerant circuit is connected to the compressor, the outdoor heat exchanger and the indoor heat exchanger in sequence. The refrigerant can flow through the compressor, the outdoor heat exchanger and the indoor heat exchanger and then flow back to the compressor. The refrigerant can be used to exchange heat with the air entering the second chamber and flowing through the outdoor heat exchanger 202.

[0141] In some embodiments, the air conditioner outdoor unit may include an outdoor heat exchange fan, which is arranged in the second chamber. The outdoor heat exchange fan drives outdoor air into the shell, and the air is blown outdoors after heat exchange with the outdoor heat exchanger.

[0142] In some embodiments, the air-conditioning outdoor unit 200 may include a throttling device 204 , which is disposed in the first chamber and configured to expand the liquid refrigerant in a high-temperature and high-pressure state into a liquid refrigerant in a low-pressure state.

[0143] The throttling device 204 can be arranged on the leeward side of the outdoor heat exchanger 202 and can be easily connected to the compressor 201 .

[0144] The air conditioner 1000 performs a refrigeration cycle of the air conditioner 1000 by using the compressor 201, the outdoor heat exchanger 202, the throttling device 204, and the indoor heat exchanger 1001. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0145] The compressor 201 compresses the low-temperature, low-pressure refrigerant gas and discharges the high-temperature, high-pressure refrigerant gas. The discharged refrigerant gas flows into the outdoor heat exchanger 202.

[0146] The outdoor heat exchanger 202 condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0147] The throttling device 204 expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the outdoor heat exchanger 202 into a low-pressure liquid-phase refrigerant.

[0148] The indoor heat exchanger 1001 evaporates the refrigerant expanded in the throttling device 204 and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor 201 .

[0149] The indoor heat exchanger 1001 can achieve a cooling effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner 1000 can adjust the temperature of the indoor space.

[0150] In both the indoor heat exchanger 1001 and the outdoor heat exchanger 202, one is a condenser and the other is an evaporator. When the indoor heat exchanger 1001 functions as a condenser and the outdoor heat exchanger 202 functions as an evaporator, the air conditioner 1000 functions as a heater in the heating mode. When the indoor heat exchanger 1001 functions as an evaporator and the outdoor heat exchanger 202 functions as a condenser, the air conditioner 1000 functions as a cooler in the cooling mode.

[0151] Reference Figure 5-Figure 12 In some embodiments, the air-conditioning outdoor unit 200 may include an electrical box 23 , and at least a portion of the electrical box 23 is disposed in the first chamber.

[0152] The electrical box is at least partially made of plastic, which has good insulation properties, effectively preventing current leakage and short circuit, and ensuring the safe operation of the electrical equipment.

[0153] In some embodiments, the air conditioner outdoor unit may include a circuit board connected to the interior of the electrical box 23. The circuit board is provided with electronic components. The circuit board may be a printed circuit board.

[0154] In some embodiments, the circuit board may include a circuit board body 25 , and the circuit board body 25 is used to carry electronic components.

[0155] In some embodiments, the plane where the circuit board body 25 is located is horizontally arranged, and the circuit board can be arranged in the small-sized housing 21. The circuit board can span the first cavity 211 and the second cavity 212, that is, at least part of the circuit board is arranged in the first cavity 211, and at least part of the circuit board is arranged in the second cavity 212, so as to reduce the space occupied in the first cavity 211.

[0156] In some embodiments, the plane where the circuit board body 25 is located is set vertically, and the circuit board can be set in a large-sized shell 21. Since the size of the shell 21 is large, the circuit board can be set entirely in the first chamber 211, and it will not have a significant impact on the space occupied by the first chamber 211. The circuit board body 25 can be set according to the size structure of the air-conditioning outdoor unit.

[0157] In some embodiments, the air conditioner outdoor unit may include a power module 26 , which is disposed on a circuit board.

[0158] The power module 26 can be an IGBT power module 26. The IGBT power module 26 generates a certain amount of heat during operation. In the circuit board, the IGBT power module is one of the main heat sources. To ensure the normal operation and reliability of the circuit board, heat dissipation measures need to be taken for the power module 26.

[0159] In some embodiments, the power module 26 includes a chip, and the periphery of the chip is wrapped with a plastic package.

[0160] In some embodiments, the power module 26 has pins, two ends of which are respectively connected to the chip and the circuit board body 25 .

[0161] In some embodiments, the air conditioner outdoor unit may include a module bracket, which is disposed between the power module 26 and the circuit board body 25. The module bracket is used to support the power module 26, thereby preventing the pins of the power module 26 connected to the circuit board body from being damaged by force, thereby preventing damage to the power module 26.

[0162] In some embodiments, the air conditioner outdoor unit may include a first heat dissipation plate 24 . The first heat dissipation plate 24 is disposed on a side of the power module 26 away from the circuit board body 25 . The first heat dissipation plate 24 is in contact with the power module 26 .

[0163] In some embodiments, the power module 26 has a connection hole, and at least one fastener can pass through the circuit board body, the connection hole, and the first heat dissipation plate to fix the power module 26 to the first heat dissipation plate 24 .

[0164] In some embodiments, the air conditioner outdoor unit may include a refrigerant radiator 208 disposed in the first chamber. The refrigerant radiator 208 contacts the first heat sink 24 to dissipate heat from the power module 26 .

[0165] In some embodiments, the refrigerant radiator 208 may include a second heat sink 28, which is located on the side of the first heat sink away from the power module. The second heat sink 28 is connected to the first heat sink, and a receiving groove 284 is provided on the side of the second heat sink 28 away from the first heat sink.

[0166] The first heat sink 24 abuts against and is connected to the power module 26. The side of the first heat sink 24 away from the power module 26 contacts the second heat sink 28, which abuts against and is connected to the first heat sink. Heat generated by the power module 26 is transferred from the first heat sink 24 to the second heat sink 28, where it is then removed through heat transfer with the refrigerant pipe 29, thereby dissipating heat from the power module 26.

[0167] In some embodiments, the refrigerant radiator 208 may include a refrigerant pipe 29 , which is disposed in the receiving tank 284 .

[0168] In some embodiments, at least two receiving grooves 284 may be provided, and the two receiving grooves 284 are arranged in parallel, and a section of the refrigerant pipe 29 passes through the two receiving grooves 284 in sequence to be connected to the receiving grooves 284 .

[0169] The receiving groove 284 is provided with an opening 2841 on the second heat sink 28 . When the refrigerant tube 29 and the receiving groove 284 are assembled, the refrigerant tube 29 is placed into the receiving groove 284 through the opening 2841 .

[0170] The refrigerant tube 29 is placed in the receiving groove 284. The refrigerant tube can be pressed into the receiving groove through a tube pressing process. The refrigerant tube 29 is pressed by external force so that the refrigerant tube 29 is deformed and squeezed toward both sides of the receiving groove 284, so that the refrigerant tube 29 is tightly attached to the inner circumference of the receiving groove 284, so that the refrigerant tube 29 is adapted to the receiving groove 284.

[0171] In some embodiments, the air conditioner outdoor unit may include a fixing member 27 fixedly connected to the second heat sink 28. A refrigerant pipe 29 is pressed into the receiving groove 284. After the fixing member 27 is fixedly connected to the second heat sink 28, the fixing member 27 is connected to the partition 22. The refrigerant pipe 29 is connected to the refrigerant circuit by welding.

[0172] In some embodiments, the air conditioner outdoor unit may include a mounting member 600. After the circuit board, power module 26, electrical box 23, and first heat sink 24 are connected, the electrical box 23 is connected to one side of the mounting member 600. After the fixing member 27 is connected to the partition 22, the mounting member 600 is connected to the partition 22.

[0173] That is, with the fixing member 27 fixedly connected to the partition 22, the refrigerant pipe 29 is connected to the refrigerant circuit. With the mounting member 600 fixedly connected to the partition 22, the fasteners are passed through the circuit board, the first heat sink 24, and the second heat sink 28 to connect the first heat sink 24 and the second heat sink 28.

[0174] In this embodiment, a fixing part 27 is provided, and the fixing part 27 is connected to the second heat sink 28. The fixing part 27 is then connected to the partition 22 to provide fixed support for the second heat sink 28 and the refrigerant tube 29, which can facilitate welding the refrigerant tube 29 to the refrigerant circuit. At this time, the circuit board and the mounting part 600 are not connected to the partition 22, so that the high temperature generated by welding the refrigerant tube 29 will not affect the reliability of the circuit board.

[0175] After the circuit board, electrical box 23, and first heat sink 24 are connected, the electrical box 23 is attached to the mounting member 600. After the fixing member 27 is fixed to the partition 22, the mounting member 600 is attached to the partition 22. At this point, at least one fastener is inserted through the circuit board body 25, the first heat sink 24, and the second heat sink 28 to connect the first heat sink 24 and the second heat sink 28.

[0176] The fixing member 27 connected to the partition 22 can position the second heat sink 28, and the mounting member 600 connected to the partition 22 can position the first heat sink 24 and the circuit board, so as to improve the connection accuracy between the first heat sink 24 and the second heat sink 28, thereby improving the assembly efficiency.

[0177] In some embodiments, the circuit board may include a fifteenth connection hole 5001 , and the fifteenth connection hole 5001 passes through the circuit board.

[0178] At least two fifteenth connection holes 5001 may be provided to facilitate fixing the circuit board.

[0179] In some embodiments, the first heat dissipation plate 24 may include a sixteenth connection hole 5002 , which corresponds to the fifteenth connection hole 5001 and passes through the first heat dissipation plate 24 .

[0180] The number of the sixteenth connection holes 5002 may be at least two, and the number of the sixteenth connection holes 5002 corresponds to the number of the fifteenth connection holes 5001 one by one.

[0181] In some embodiments, the second heat dissipation plate 28 may include seventeenth connection holes 5003 , and the number of the seventeenth connection holes 5003 corresponds one-to-one to the number of the sixteenth connection holes 5002 .

[0182] In some embodiments, the seventeenth connection hole 5003 passes through the second heat dissipation plate 28 .

[0183] In some embodiments, the fifteenth connecting hole 5001 , the sixteenth connecting hole 5002 , and the seventeenth connecting hole 5003 may be configured as threaded holes.

[0184] In some embodiments, the module connection hole 2601 of the power module 26 is not concentrically arranged with the sixteenth connection hole 5002, so that the power module 26 and the second heat sink 28 are not connected by fasteners, so that the second heat sink 28 can be separated from the first heat sink 24 by removing the fasteners passing through the sixteenth connection hole 5002 and the seventeenth connection hole 5003, thereby facilitating the disassembly and replacement of the circuit board, making the maintenance of the circuit board more convenient.

[0185] When the mounting member 600 is connected to the partition 22 and the fixing member 27 is connected to the partition 22, the sixteenth connecting hole 5002 corresponds to the seventeenth connecting hole 5003, and the fastener can pass through the fifteenth connecting hole 5001. The fastener passes through the sixteenth connecting hole 5002 and the seventeenth connecting hole 5003 to connect the first heat dissipation plate 24 with the second heat dissipation plate 28.

[0186] The refrigerant radiator 208 is connected to the fixing member 27, and the fixing member 27 is connected to the partition 22, so that the refrigerant radiator 208 can be pre-positioned, making it easier to pre-fix the refrigerant radiator 208 in the air conditioner outdoor unit.

[0187] After the circuit board, the electrical box 23, and the first heat sink 24 are connected, the electrical box 23 is connected to the mounting member 600. Connecting the mounting member 600 to the partition 22 pre-positions the circuit board, the electrical box 23, and the first heat sink 24, facilitating their pre-fixation within the air conditioner outdoor unit. This positioning reduces installation errors between the circuit board, the first heat sink 24, and the second heat sink 28, specifically, between the fifteenth connection hole 5001, the sixteenth connection hole 5002, and the seventeenth connection hole 5003, thereby improving assembly efficiency of the circuit board, the first heat sink 24, and the second heat sink 28.

[0188] In some embodiments, fasteners may be provided to pass through the circuit board body 25 and the first heat sink 24 to connect the circuit board body 25 and the first heat sink 24, thereby preventing the pins of the power module 26 disposed between the circuit board body 25 and the first heat sink 24 from being subjected to stress.

[0189] In some embodiments, the power module 26 is connected to the first heat sink 24, and the first heat sink 24 is connected to the second heat sink 28. The power module 26 and the second heat sink 28 are not connected by fasteners. Therefore, when the circuit board needs to be disassembled for maintenance, it is only necessary to remove the fasteners connecting the first heat sink 24 and the second heat sink 28 to loosen the connection between the first heat sink 24 and the second heat sink 28. Since the first heat sink is connected to the circuit board and the second heat sink is connected to the fixing member located on the outdoor unit, when the first heat sink and the second heat sink are separated, the circuit board can be separated from the outdoor unit. There is no need to remove the fasteners between the first heat sink 24 and the circuit board body 25, nor is there any need to remove the connection between the second heat sink 28 and the fixing member 27. This reduces the number of fasteners that need to be removed, improves maintenance efficiency, and does not require the second heat sink to be detached from the outdoor unit, thereby improving disassembly convenience.

[0190] On the other hand, the pins of the power module are generally easy to break. After the product leaves the factory, it is generally not advisable to remove the fasteners that secure the power module to the first heat sink. Therefore, compared to the situation where the same fasteners are directly connected to the power module, the first heat sink, and the second heat sink, this solution adopts a method of connecting the power module and the second heat sink without fasteners. When disassembling, there is no need to remove the screws between the power module and the first heat sink to remove the circuit board from the outdoor unit. In other words, when the circuit board is removed, the fasteners between the power module and the first heat sink remain connected. This means that when the circuit board is reinstalled in the outdoor unit, there is no need to use fasteners to connect the power module and the first heat sink again, reducing the number of times the fasteners on the power module need to be loosened or tightened, and reducing the risk of breakage of the power module pins.

[0191] In some embodiments, the mounting member 600 is detachably connected to the partition 22, so that the mounting member 600 and the partition 22 can be processed and installed separately, so that the circuit board, the electrical box 23 and the first heat sink 24 can be assembled with the mounting member 600 first, and then the mounting member 600 can be connected to the partition 22 as a whole after installation, so that there is no need to assemble the circuit board, the electrical box 23 and the first heat sink 24 with the mounting member 600 separately on the subsequent assembly production line, and the assembled mounting member 600 can be directly connected to the partition 22 as a whole, thereby improving assembly efficiency.

[0192] In some embodiments, the fixing member 27 is detachably connected to the partition 22, so that the fixing member 27 and the partition 22 can be processed and installed separately, so that the second heat dissipation plate 28 and the refrigerant pipe can be assembled with the fixing member 27 first, and then the fixing member 27 is connected to the partition 22 as a whole after assembly, so that the second heat dissipation plate 28, the refrigerant pipe and the fixing member 27 do not need to be assembled separately on the subsequent assembly production line, and the assembled fixing member 27 can be directly connected to the partition 22 as a whole, making the assembly quick and efficient.

[0193] In some embodiments, the electrical box 23 may include a first assembly port 2001 . The first assembly port is disposed on a side of the electrical box 23 close to the second heat sink 28 . The first assembly port 2001 passes through the electrical box 23 .

[0194] The first heat sink 24 is arranged on a side of the electrical box 23 away from the circuit board and corresponding to the first assembly port 2001. The first heat sink 24 can completely cover the first assembly port 2001. The first heat sink 24 can be connected to the power module 26 through the first assembly port 2001, thereby facilitating the first heat sink 24 to dissipate heat from the power module 26.

[0195] In some embodiments, the electrical box 23 may include a connecting column 2002 , and an eighteenth connecting hole 2003 is provided on the connecting column 2002 . The depth direction of the eighteenth connecting hole 2003 is the same as the axial direction of the connecting column 2002 .

[0196] In some embodiments, the eighteenth connecting hole 2003 can be set as a threaded hole.

[0197] In some embodiments, the circuit board abuts the connecting column 2002, and the fastener passes through the circuit board and the eighteenth connecting hole 2003 to fix the circuit board to the electrical box 23, thereby achieving pre-assembly of the electrical box 23 and the circuit board, which can improve the assembly efficiency on the production line.

[0198] In some embodiments, at least two connecting pillars 2002 may be provided to improve the fixing effect on the circuit board.

[0199] In some embodiments, the power module 26 is correspondingly disposed in the first assembly opening 2001 , and fasteners pass through the circuit board, the power module 26 and the first heat sink 24 to connect the power module 26 and the first heat sink 24 .

[0200] By placing the circuit board against the connecting pillars 2002 and connecting the circuit board to the electrical box 23 , the pins of the power module 26 can be prevented from being damaged by force.

[0201] In some embodiments, the mounting member 600 may include a third positioning hole 6005 , which passes through the mounting member 600 .

[0202] The electrical box 23 may include a third positioning portion 2005 . The third positioning portion 2005 is disposed at the bottom of the installation box. The third positioning portion 2005 is integrally provided with the installation box.

[0203] The third positioning portion 2005 is matched and connected with the third positioning hole 6005 to position and install the electrical box 23 on the mounting member 600 .

[0204] In some embodiments, the mounting member 600 may include a nineteenth connection hole 6001, which passes through the mounting member, and the electrical box 23 includes a twentieth connection hole 2004, which corresponds to the nineteenth connection hole 6001. The fastener passes through the nineteenth connection hole 6001 and the twentieth connection hole 2004 to connect the electrical box 23 and the mounting member 600, thereby assembling the electrical box 23 on the mounting member 600.

[0205] The fastener passes through the nineteenth connecting hole 6001 and the twentieth connecting hole 2004 to connect the electrical box 23 and the mounting part 600. The electrical box 23 can be connected to the mounting part 600 in advance, realizing the pre-assembly of the electrical box 23 and the mounting part 600, which can save the assembly process on the assembly production line and improve the assembly efficiency on the assembly production line.

[0206] See also Figures 13-19 In some embodiments, the electric box 23 may not be provided in the air conditioner outdoor unit, electronic components are provided on the circuit board, and the power module 26 is provided on the circuit board.

[0207] The circuit board may include a circuit board body 25 , and the circuit board body 25 is used to carry electronic components.

[0208] In some embodiments, the air conditioner outdoor unit may include a power module 26 , which is disposed on a circuit board.

[0209] The power module 26 can be an IGBT power module 26. The IGBT power module 26 generates a certain amount of heat during operation. In the circuit board, the IGBT power module is one of the main heat sources. To ensure the normal operation and reliability of the circuit board, heat dissipation measures need to be taken for the power module 26.

[0210] In some embodiments, the power module 26 includes a chip, and the periphery of the chip is wrapped with a plastic package.

[0211] In some embodiments, the power module 26 has pins, two ends of which are respectively connected to the chip and the circuit board body 25 .

[0213] In some embodiments, the power module 26 has a module connection hole 2601 , and at least one fastener can pass through the circuit board body 25 , the module connection hole 2601 , and the first heat dissipation plate 24 to fix the power module 26 to the first heat dissipation plate 24 .

[0214] In some embodiments, the first heat dissipation plate 24 may include a twenty-third connection hole, which corresponds to the module connection hole 2601 and passes through the first heat dissipation plate 24 .

[0215] At least one fastener passes through the module connection hole 2601 and the twenty-third connection hole to connect the power module 26 and the first heat sink 24 .

[0216] In some embodiments, the twenty-third connecting hole and the sixteenth connecting hole 5002 are not arranged concentrically, so that the power module 26 and the second heat sink 28 are not connected by fasteners, so that the second heat sink 28 can be separated from the first heat sink 24 by removing the fasteners passing through the sixteenth connecting hole 5002 and the seventeenth connecting hole 5003, thereby facilitating the disassembly and replacement of the circuit board, making the maintenance of the circuit board more convenient.

[0217] In some embodiments, the air conditioner outdoor unit may include a refrigerant radiator 208 disposed in the first chamber. The refrigerant radiator 208 contacts the first heat sink 24 to dissipate heat from the power module 26 .

[0218] In some embodiments, the refrigerant radiator 208 may include a second heat sink 28, which is located on the side of the first heat sink away from the power module.

[0219] The first heat sink 24 abuts against and is connected to the power module 26. The side of the first heat sink 24 away from the power module 26 contacts the second heat sink 28, which abuts against and is connected to the first heat sink. Heat generated by the power module 26 is transferred from the first heat sink 24 to the second heat sink 28, where it is then removed through heat transfer with the refrigerant pipe 29, thereby dissipating heat from the power module 26.

[0220] In some embodiments, the refrigerant radiator 208 may include a refrigerant pipe 29 , which is disposed in the receiving tank 284 .

[0221] In some embodiments, the air conditioner outdoor unit may include a fixing member 27 connected to a second heat sink 28. A refrigerant pipe 29 is pressed into the receiving groove 284.

The refrigerant pipe 29 can be connected to the refrigerant circuit by welding.

[0222] In some embodiments, the air conditioner outdoor unit may include a mounting member 600, one side of which is connected to a circuit board. Specifically, after the circuit board, power module 26, and first heat sink 24 are connected, the circuit board is connected to one side of the mounting member 600. After the fixing member 27 is connected to the partition 22, the mounting member 600 is connected to the partition 22. Fasteners penetrate the circuit board, the first heat sink 24, and the second heat sink 28 to connect the first heat sink 24 to the second heat sink 28.

[0223] The refrigerant radiator 208 is connected to the fixing member 27, and the fixing member 27 is connected to the partition 22, so that the refrigerant radiator 208 can be pre-positioned, making it easier to pre-fix the refrigerant radiator 208 in the air conditioner outdoor unit.

[0224] After the circuit board, power module 26, and first heat sink 24 are connected, the circuit board is then connected to the mounting member 600. Connecting the mounting member 600 to the partition 22 pre-positions the circuit board, power module 26, and first heat sink 24, facilitating their pre-fixation within the air conditioner outdoor unit. This positioning reduces installation errors between the circuit board, first heat sink 24, and second heat sink 28, improving assembly efficiency.

[0225] In some embodiments, the mounting member 600 is detachably connected to the partition 22, so that the mounting member 600 and the partition 22 can be processed and installed separately, so that the circuit board and the first heat sink 24 can be assembled with the mounting member 600 first, and then the mounting member 600 can be connected as a whole to the partition 22 after installation, so that there is no need to assemble the circuit board and the first heat sink 24 with the mounting member 600 separately on the subsequent assembly production line, and the assembled mounting member 600 can be directly connected as a whole to the partition 22, thereby improving assembly efficiency.

The assembly hole 25003 cooperates with the assembly pin 6003. The assembly pin 6003 is inserted into the assembly hole 25003 to connect the circuit board and the mounting piece 600, which can avoid pressing the power module 26 and prevent the pins of the power module 26 from being damaged by force.

[0236] The first heat sink 24 is smaller than the second assembly opening 6004 so that the first heat sink 24 can be disposed in the second assembly opening 6004. Fasteners pass through the circuit board, the power module 26, and the first heat sink 24 to secure the first heat sink 24 to the power module 26.

[0245] The refrigerant radiator 208 is connected to the fixing member 27, and the fixing member 27 is connected to the partition 22, so that the refrigerant radiator 208 can be pre-positioned, making it easier to pre-fix the refrigerant radiator 208 in the air conditioner outdoor unit.

[0246] After the circuit board is connected to the first heat sink 24, the circuit board is attached to the mounting member 600. Connecting the mounting member 600 to the partition 22 pre-positions the circuit board and the first heat sink 24, facilitating the pre-fixation of the circuit board, the electrical box 23, and the first heat sink 24 within the air conditioner outdoor unit. This positioning reduces installation errors between the circuit board, the first heat sink 24, and the second heat sink 28, specifically, between the fifteenth connection hole 5001, the sixteenth connection hole 5002, and the seventeenth connection hole 5003, thereby improving assembly efficiency of the circuit board, the first heat sink 24, and the second heat sink 28.

[0247] In some embodiments, the fixing member 27 can be detachably connected to the partition 22, which can facilitate separate processing of the fixing member 27 and the partition 22, so that the partition 22 has a universal design, so that the partition 22 can be suitable for other models, and the fixing member 27 and the refrigerant radiator 208 can be pre-assembled, thereby reducing the assembly process on the assembly production line and improving assembly efficiency.

[0248] In some embodiments, the mounting member 600 is configured as sheet metal for easy processing and forming. The mounting member 600 can be detachably connected to the partition 22, which allows for separate processing of the mounting member 600 and the partition 22. This allows the partition 22 to have a universal design, making it suitable for other models. The mounting member 600 can also be pre-assembled with the refrigerant radiator 208, thereby reducing the assembly process on the assembly line and improving assembly efficiency.
