Description

Technical Field

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

[0002] The outdoor unit of an air conditioner is an important component of the air conditioning system. Its main function is to transfer heat from the indoor unit to the outdoor unit through the circulation of refrigerant, thereby regulating the indoor temperature. The electrical control box assembly and radiator are key parts of the outdoor unit for electrical control and heat dissipation. It typically includes components such as the electrical control box, electrical control board, and refrigerant radiator.

[0003] In related technologies, due to space limitations inside the outdoor unit of an air conditioner, refrigerant radiators are often fixed on the front of the control board and on the side where various components are located. This arrangement makes the cooling pipes of the refrigerant radiator close to the electrical components on the circuit board. The low temperature of the refrigerant pipes may affect the operation of the electrical components or cause damage to them, thus affecting the stability and reliability of the air conditioner's operation.

[0004] To address the aforementioned technical issues, one solution involves mounting the refrigerant radiator on the back of the control board. The radiator is directly fixed to the heating module with screws, requiring the disassembly of multiple components for maintenance, resulting in low efficiency and hindering the welding of cooling pipes. Furthermore, the installation of the housing lacks positioning mechanisms, and the refrigerant radiator lacks effective positioning and securing measures. Relying solely on screws to connect the refrigerant radiator to the heating module not only makes aligning the screw holes between the radiator and the heating module difficult, affecting assembly accuracy and efficiency, but also makes the radiator prone to loosening or poor contact during long-term operation, impacting the reliability and stability of the air conditioning system. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore, This utility model provides an outdoor unit for an air conditioner, which includes: A partition is provided inside the housing to divide the accommodating space into a fan chamber and a compressor chamber; An outdoor fan is installed inside the fan cavity; An electrical control box, disposed on the partition and located within the press chamber, the electrical control box comprising: The outer casing is located on the side of the partition facing the press chamber; A box body is provided on the outer shell, and the box body is provided with a through opening and a second through hole; An electronic control board is disposed on the box body. A heating module is disposed on the side of the electronic control board. The electronic control board is provided with a first through hole for the first fastener to pass through. A modular heat sink is installed on the side of the box facing the partition. The modular heat sink abuts against the heat-generating module through the opening. A third through hole is provided on the modular heat sink. A pre-positioning structure is disposed on the partition plate, the pre-positioning structure comprising: The first flange is perpendicular to the height direction of the partition. Two second flanges are arranged at intervals along the length direction of the first flange, and the two second flanges extend along the height direction of the partition and enclose the first flange to form a receiving part; A refrigerant radiator is supported on the first flange and at least part of it is located in the receiving portion, and the refrigerant radiator is provided with a first mounting hole; When the electrical control box is installed on the partition, the first mounting hole and the third through hole are aligned. The first fastener passes through the first through hole, the second through hole, and the third through hole in sequence and is connected to the first mounting hole so that the module heat sink abuts against the refrigerant heat sink.

[0006] The above technical solution has the following advantages or beneficial effects: The heating module is attached to the refrigerant radiator through a modular heat sink, which can efficiently transfer the heat it generates to the refrigerant radiator through the modular heat sink, so as to utilize the cooling capacity of the refrigerant to dissipate heat from the heating module, thereby improving heat dissipation efficiency and ensuring the stable operation of the outdoor unit of the air conditioner. The pre-positioning structure allows the refrigerant radiator to be quickly and accurately positioned on the partition, ensuring that the positions of the third through hole and the first mounting hole can be accurately located when fixing the modular heat sink and the refrigerant radiator, realizing the rapid fixing of the modular heat sink and the refrigerant radiator. During maintenance, the electrical control box can be disassembled and removed from the front, improving maintenance efficiency.

[0007] According to an embodiment of this disclosure, two second flanges are located on both sides of the refrigerant radiator, and the single-sided gap between the second flange and the refrigerant radiator is a, where 0 mm < a and a ≤ 0.5 mm.

[0008] The above technical solution has the following advantages or beneficial effects: The second flange limits the width of the refrigerant radiator on both sides. If the single-sided gap 'a' is greater than 0.5mm, the third through hole and the first mounting hole cannot be automatically aligned, requiring manual alignment and reducing assembly efficiency. If the single-sided gap 'a' is ≤0mm, the refrigerant radiator cannot naturally adhere to the first flange under gravity, causing the pre-positioning to become an interference fit, leading to assembly difficulties, inaccurate positioning, and damage to the second flange, affecting the pre-positioning function. Setting the single-sided gap 'a' within a reasonable range of 0~0.5mm ensures high positional accuracy of the refrigerant radiator on the partition, and allows it to be placed on the first flange by gravity during installation and automatically, quickly, and accurately align the corresponding through hole and mounting hole, improving installation efficiency and reliability.

[0009] According to an embodiment of this disclosure, the partition is provided with a second mounting hole, and the refrigerant radiator is provided with a fourth through hole for the second fastener to pass through. When the refrigerant radiator is located on the prepositioning structure, the second mounting hole is aligned with the fourth through hole, and the second fastener passes through the fourth through hole and is connected to the second mounting hole.

[0010] The above technical solution has the following advantages or beneficial effects: by using the second fastener to fix the refrigerant radiator to the partition, the connection between the refrigerant radiator and the partition is more secure, which avoids the refrigerant radiator from loosening due to vibration and other reasons, and further improves the positioning accuracy of the refrigerant radiator.

[0011] According to an embodiment of this disclosure, the top of the partition is provided with a positioning flange extending toward the fan cavity, the positioning flange is provided with at least one positioning part, and the top of the outer shell is provided with a hook, the hook being adapted to be connected to the positioning part for positioning the outer shell on the partition.

[0012] The above technical solution has the following advantages or beneficial effects: By setting a positioning flange and positioning part, the outer shell can be first hooked into the positioning part during installation, thereby freeing the operator's hands, facilitating subsequent installation and fixing, and greatly improving the convenience of installation. At the same time, the positioning part is adapted to the hook for initial positioning of the outer shell, ensuring its accurate position on the partition and improving installation efficiency.

[0013] According to an embodiment of this disclosure, the hook includes a support portion and a guide portion. The support portion is connected to the outer shell, one end of the guide portion is connected to the support portion, and the other end extends downward to form a free end for passing through the positioning portion.

[0014] The above technical solution has the following advantages or beneficial effects: the downward-extending free end of the guide portion allows the hook to be inserted into the positioning portion from top to bottom, enabling the operator to align the hook with the positioning portion by feel without visual inspection, thus improving assembly efficiency. During assembly, the free end of the guide portion can pass through the positioning portion first, and the outer shell relies on gravity to make the support portion abut against the positioning flange, avoiding stress concentration at the root of the hook and extending the fatigue life of the hook and positioning portion.

[0015] According to an embodiment of this disclosure, the positioning part has positioning edges on opposite sides, and the single-sided gap between the positioning edge and the hook is b, where 0mm < b and b ≤ 0.2mm.

[0016] The above technical solution has the following advantages or beneficial effects: A single-sided gap b greater than 0.2mm will lead to a loss of positioning accuracy of the outer shell on the partition, resulting in difficulties in the subsequent fixed connection and alignment of the outer shell and the partition, increasing assembly time. When the single-sided gap b ≤ 0mm, the clearance fit between the hook and the positioning part cannot be guaranteed, requiring external force to forcibly press the hook in, which may damage the hook or the positioning flange, increasing assembly difficulty. Setting the single-sided gap b within a reasonable range of 0~0.2mm balances assembly tolerance and positioning accuracy, ensuring the fit accuracy between the hook and the positioning part, and further improving the installation accuracy and stability of the outer shell on the partition.

[0017] According to an embodiment of this disclosure, the outer shell is provided with at least one slot, and the box body is provided with at least one plug-in portion, the plug-in portion being adapted to be connected in the slot for positioning the box body on the outer shell.

[0018] The above technical solution has the following advantages or beneficial effects: the slot on the outer shell is adapted to the plug-in part on the box, which can quickly and accurately position the box on the outer shell, improve the installation efficiency of the box, reduce the installation time, and facilitate the subsequent fixing between the box and the outer shell.

[0019] According to an embodiment of this disclosure, the slot includes a first sidewall disposed opposite to each other and a bottom wall abutting against the insertion portion. The two first sidewalls are respectively connected to the two ends of the bottom wall through guide sidewalls, and the gap between the two guide sidewalls gradually decreases from top to bottom.

[0020] The above technical solution has the following advantages or beneficial effects: by setting the above-mentioned guide sidewall, the insertion part of the box can be guided smoothly into the slot, reducing the time and effort required for insertion, enabling operators to quickly complete the insertion operation, thereby improving the overall assembly efficiency.

[0021] According to an embodiment of this disclosure, the insertion part and the guide sidewall have a minimum single-sided gap c, where 0 < c, c ≤ 0.2 mm.

[0022] The above technical solution has the following advantages or beneficial effects: A single-sided gap c greater than 0.2mm will lead to a loss of positioning accuracy of the box on the outer shell, resulting in difficulties in the subsequent fixed connection and alignment of the box and the outer shell, increasing assembly time. When the single-sided gap c ≤ 0mm, it is impossible to guarantee the fit between the insertion part and the bottom end of the guide sidewall, requiring external force to force the insertion part into contact with the bottom wall, which may damage the insertion part or the slot, increasing assembly difficulty. Setting the single-sided gap c within a reasonable range of 0~0.2mm achieves an optimal balance between assemblability and positioning stability. The guide sidewall achieves progressive positioning, and with a reasonable single-sided gap c, precise positioning is finally achieved through bottom wall contact, ensuring extremely high positional accuracy of the box on the outer shell, thereby guaranteeing the assembly accuracy and efficiency of the entire electrical control box assembly.

[0023] According to an embodiment of this disclosure, the guide portion extends obliquely downwards in a direction away from the partition.

[0024] The above technical solution has the following advantages or beneficial effects: by setting a guide part that extends inclinedly from top to bottom away from the partition, the hook can be inserted into the positioning part more smoothly during installation, reducing installation resistance and improving the convenience and efficiency of installation.

[0032] The outdoor unit 100 of the air conditioner provided in this utility model can have various implementation forms, as detailed below. Figures 1-14 Describe the outdoor unit 100 of the air conditioner.

[0033] It should be noted that the outdoor unit 100, as the outdoor unit of the air conditioner, is usually located outdoors and exchanges heat with the outdoor environment to carry indoor heat to the outside. The air conditioner also includes an indoor unit, while the outdoor unit is located indoors and exchanges heat with the indoor environment.

[0034] refer to Figure 1 , Figure 2 In one illustrative embodiment of the air conditioner outdoor unit 100 provided by this utility model, the air conditioner outdoor unit 100 includes a housing 1, which is installed outdoors and forms the overall appearance of the air conditioner outdoor unit 100.

[0035] The housing 1 defines an internal space for installing and securing the various components of the outdoor unit 100 of the air conditioner. The housing 1 has a top end and a bottom end, which are the two ends of the housing 1 that are positioned opposite each other in the height direction.

[0036] Continue to refer to Figure 1 , Figure 2The housing 1 may include an air inlet 11. The air inlet 11 is connected to the receiving space and serves as the inlet for external air to flow into the housing 1.

[0037] The housing 1 may include an air outlet 12. The air outlet 12 is connected to the receiving space and serves as the outlet for the heat-exchanged air to flow out of the housing 1.

[0038] Outdoor air from outside the casing 1 enters the casing 1 through the air inlet 11 and is finally exhausted to the outside through the air outlet 12.

[0039] In some embodiments of this application, reference is made to Figure 3 The outdoor unit 100 of the air conditioner may include an air outlet grille 13, which is connected to the housing 1 and located at the air outlet 12 to serve both the functions of air rectification and air guidance, as well as safety protection.

[0040] It should be noted that the directions described in the text are based on the direction in which the user faces the outdoor unit 100 of the air conditioner. Specifically, the side of the outdoor unit 100 facing the user when in use is defined as the front side, and the opposite side is defined as the rear side. The left and right sides are distinguished by the direction in which the user faces the outdoor unit 100 of the air conditioner.

[0041] Continue to refer to Figure 3 The outdoor unit 100 of the air conditioner may include a partition 4. The partition 4 is disposed in the housing and is used to divide the accommodating space inside the housing 1 into a fan chamber 51 and a compressor chamber 52.

[0042] The partition 4 is disposed inside the housing 1 along the height direction of the housing. In this embodiment, the fan chamber 51 and the compressor chamber 52 are located on the left and right sides of the housing 1, respectively.

[0043] In some embodiments of this application, the air inlet 11 may be located on the rear side of the housing 1, and the air outlet 12 may be located on the front side of the housing 1. In this embodiment, the air outlet 12 is located on the front panel of the housing 1.

[0044] Of course, in some other embodiments, the air inlet 11 may also be located on the side of the housing 1, that is, the air inlet 11 may be located on the rear side and / or the side of the housing 1. The air inlet 11 is connected to the fan cavity 51.

[0045] In some embodiments of this application, the outdoor unit 100 of the air conditioner may include an outdoor heat exchanger 2, which is disposed inside the fan cavity 51 for heat exchange with the air inside the casing 1. The outdoor heat exchanger 2 is located inside the air inlet 11.

[0046] The outdoor heat exchanger 2 can be a plate heat exchanger. In order to increase the heat exchange area of ​​the outdoor heat exchanger 2 while minimizing the size of the outdoor unit 100, the outdoor heat exchanger 2 can be set as an L-shaped heat exchanger in this embodiment.

[0047] When outdoor heat exchanger 2 is an L-shaped heat exchanger, it is installed on the air inlet side. That is, refer to... Figure 2 , Figure 3 One part of the outdoor heat exchanger 2 corresponds to the air inlet 11 on the rear side of the casing 1, and the other part of the outdoor heat exchanger 2 corresponds to the air inlet 11 on the side of the casing 1.

[0048] In some embodiments of this application, the outdoor unit 100 of the air conditioner may include an outdoor fan 3, which is disposed within the fan cavity 51. The outdoor fan 3 may be an axial flow fan.

[0049] refer to Figure 3 The outdoor fan 3 can be set towards the air outlet 12, that is, the outdoor fan 3 is set on the side of the outdoor heat exchanger 2 away from the air inlet 11.

[0050] In this embodiment, the outdoor fan 3 is installed between the outdoor heat exchanger 2 and the air outlet 12. Under the action of the outdoor fan 3, outdoor air enters the fan chamber 51 through the air inlet 11. The outdoor air exchanges heat with the outdoor heat exchanger 2 in the fan chamber 51. The outdoor air after heat exchange is discharged from the casing 1 through the air outlet 12 under the drive of the outdoor fan 3.

[0051] The outdoor fan 3 may include two axial flow fans spaced apart in a vertical direction. In this embodiment, the housing 1 has air outlets 12 that correspond one-to-one with the two axial flow fans.

[0052] The outdoor fan 3 with dual axial flow can provide higher air volume and more uniform airflow distribution, improve heat exchange efficiency, and ensure sufficient airflow, thereby enabling more effective heat exchange.

[0053] The outdoor unit 100 of the air conditioner may include a compressor, which is located in the compressor chamber 52.

[0054] The air conditioner may include a throttling device for limiting airflow. The throttling device may be located in the outdoor unit 100 or the indoor unit of the air conditioner.

[0055] An air conditioner may include a refrigerant circuit. A refrigerant circuit is formed by connecting pipes between the indoor unit and the outdoor unit 100 of the air conditioner. Through this refrigerant circuit, the air conditioner allows the refrigerant to circulate sequentially through the compressor, condenser, throttling device, and evaporator, enabling it to perform indoor cooling or heating.

[0056] An air conditioner may include an indoor unit, which includes an indoor heat exchanger.

[0057] The indoor heat exchanger and outdoor heat exchanger 2 are used as condensers or evaporators. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in heating mode; when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in cooling mode.

[0058] Refrigeration and heating cycles include compression, condensation, expansion, and evaporation processes. They provide cooling or heating to the indoor space through the heat absorption and release processes of the refrigerant, thereby regulating the temperature of the indoor space.

[0059] The compressor compresses the refrigerant gas into a high-temperature, high-pressure state and discharges the compressed refrigerant gas, which then flows into the condenser.

[0060] The condenser condenses the compressed, high-temperature, high-pressure gaseous refrigerant into a liquid refrigerant, and the heat is released to the surrounding environment through the condensation process.

[0061] The liquid refrigerant flowing out of the condenser enters the throttling device, which expands the high-temperature, high-pressure liquid refrigerant after condensation in the condenser into a low-pressure liquid refrigerant.

[0062] The low-pressure liquid refrigerant flowing out of the throttling device enters the evaporator. As the liquid refrigerant flows through the evaporator, it absorbs heat and evaporates into a low-temperature, low-pressure refrigerant gas. The low-temperature, low-pressure refrigerant gas returns to the compressor.

[0063] The evaporator achieves its cooling effect by exchanging heat with the material being cooled using the latent heat of refrigerant evaporation. Throughout this entire cycle, the air conditioner regulates the temperature of the indoor space.

[0064] In some embodiments of this application, the outdoor unit 100 of the air conditioner may include an electrical control box assembly disposed on the partition 4.

[0065] The electrical control box assembly may include an electrical control board 7, which is used to receive signals, analyze signals, and issue control commands to realize the electrical control functions of the outdoor unit 100 of the air conditioner.

[0066] Among them, the electronic control board 7 is electrically connected to at least the compressor, the throttling device and the outdoor fan, in order to control the operation of the compressor, the throttling device and the outdoor fan.

[0067] It is understood that the electronic control board 7 may include a board body and several electrical components disposed on the board body, which is prior art in this field and will not be described in detail here.

[0068] In this embodiment, the electrical control box assembly is located in the compressor chamber 52 to prevent the outdoor fan from spinning water onto the electrical control box assembly.

[0069] The electrical control box assembly may include an electrical control box 6, on which a receiving portion is formed for mounting and accommodating an electrical control board 7. The electrical control board 7 can be snapped into the receiving portion.

[0070] By providing a housing, a stable installation space can be provided for the control board 7, ensuring that the control board 7 is firmly fixed in the control box 6, and preventing the control board 7 from loosening due to vibration or external force, thereby improving the reliability of the control system of the outdoor unit of the air conditioner.

[0071] refer to Figure 4 The electrical control box 6 may include a housing 61, which is located on the side of the partition 4 facing the press chamber 52.

[0072] The outer casing 61 is a sheet metal part. Using sheet metal as the outer casing 61 provides high strength and rigidity, enabling it to provide a stable and reliable support structure for the electrical control box 6, ensuring the stability of the electrical control box 6 during installation and use.

[0073] The electrical control box 6 may include a box body 62, which is disposed on the outer casing 61. (Continue to refer to...) Figure 4 The box body 62 is connected to the side of the outer shell 61 away from the partition 4, and the receiving part is formed on the side of the box body 62 away from the outer shell 61.

[0074] The housing 62 can be made of plastic. Using plastic as the housing 62 for mounting the electrical control board 7 improves electrical safety.

[0075] refer to Figure 8A , Figure 9 The control board 7 has a through hole 72 for the first fastener 101 to pass through. The housing 62 has a through hole 622, which is provided corresponding to the first through hole 72, and at least one of the first through hole 72 and the second through hole 622 is provided.

[0076] An electronic control board 7 is mounted on the housing 62, and a heating module 71 is mounted on the side of the electronic control board 7. (Reference) Figure 8B The heating module 71 is located on the side of the electronic control board 7 near the partition 4, that is, the heating module 71 is located on the back of the electronic control board 7, and other components are located on the front of the electronic control board 7.

[0077] In this embodiment, the heating module 71 is placed on the back of the electronic control board 7, which can isolate it from other components on the electronic control board 7, which is conducive to heat dissipation, avoids heat accumulation from adversely affecting other components on the electronic control board 7, and improves the heat dissipation performance and stability of the electronic control system.

[0078] The heating module 71 has pins that are soldered to the control board 7. The heating module 71 is the module that is prone to heat generation when the control board 7 is working. The heating module 71 can be all or part of the compressor's IPM module, IGBT switching transistor, PFC diode FRD, rectifier bridge, and outdoor fan's IPM module.

[0079] Since the heating module 71 on the electronic control board 7 easily generates a large amount of heat when it is working, it is necessary to dissipate heat from the heating module 71. In order to achieve heat dissipation of the electronic control board 7, in some embodiments of this application, the electronic control box assembly may include a module heat sink 81, which is attached to the heating module 71 to transfer the heat generated by the heating module 71.

[0080] The module heat sink 81 can be a heat-conducting plate. The module heat sink 81 can be made of materials with good thermal conductivity, such as aluminum or copper.

[0081] Further reference Figure 10 The outdoor unit of the air conditioner may include a refrigerant radiator 82, which is attached to the side of the modular radiator 81 away from the heat-generating module 71. The refrigerant radiator 82 uses the cooling capacity of the refrigerant to dissipate the heat transferred by the modular radiator 81.

[0082] In this embodiment, when the control board 7 is working, the heat generated by the heating module 71 is directly absorbed and transferred by the module heat sink 81. Through the contact between the refrigerant heat sink 82 and the module heat sink 81, the cooling capacity of the refrigerant can effectively dissipate the heat transferred by the module heat sink 81, improving heat dissipation efficiency and ensuring that the heating module 71 remains within a suitable temperature range during operation, thus extending its service life. Compared to existing air-cooled heat sinks, the heat dissipation effect using refrigerant is superior.

[0083] In some embodiments of this application, the housing 62 is provided with a through opening 621. The opening 621 corresponds to the heating module 71. The module heat sink 81 and the heating module 71 can abut against each other at the through opening 621.

[0084] By providing opening 621, the module heat sink 81 can directly contact the heat-generating module 71, further improving the heat dissipation effect. At the same time, the design of opening 621 also facilitates heat conduction and dissipation, preventing heat from accumulating inside the electrical control box 6 and improving the heat dissipation performance of the entire electrical control system.

[0085] In some embodiments of this application, a through portion 611 is provided on the outer casing 61 corresponding to the module heat sink 81, wherein the module heat sink 81 abuts against the refrigerant heat sink 82 through the through portion 611.

[0086] By providing a through section 611, the module heat sink 81 can directly contact the refrigerant heat sink 82, thereby improving the heat dissipation effect of the heat-generating module 71.

[0087] In some embodiments of this application, the outdoor unit 100 of the air conditioner may include a prepositioning structure 9, which is disposed on the partition 4 and is used to position the refrigerant radiator 82 on the partition 4 to ensure that the position of the refrigerant radiator 82 on the partition 4 is accurate and to avoid positional deviation during installation.

[0088] When the electrical control box is installed on the partition 4, the module heat sink 81 and the refrigerant heat sink 82 are connected and fixed by the first fastener 101 passing through the first through hole 72 and the second through hole 811.

[0089] For details, please refer to Figure 9 , Figure 10 The refrigerant radiator 82 is provided with a first mounting hole 821, and the module radiator 81 is provided with a third through hole 811. When the refrigerant radiator 82 is located on the prepositioning structure 9 and the electrical control box 6 is located on the partition 4, the first mounting hole 821 and the third through hole 811 are aligned. The first fastener 101 passes through the first through hole 72, the second through hole 622, and the third through hole 811 in sequence and is connected to the first mounting hole 821 so that the module radiator 81 and the refrigerant radiator 82 abut against each other.

[0090] In this embodiment, by setting a pre-positioning structure 9, the position of the refrigerant radiator 82 on the partition plate 4 can be quickly and accurately positioned, ensuring that the position of the third through hole 811 and the first mounting hole 821 can be accurately located when the module radiator 81 and the refrigerant radiator 82 are fixed, thus realizing the quick fixing of the module radiator 81 and the refrigerant radiator 82. During maintenance, the electrical control box 6 can be disassembled and removed from the front, improving maintenance efficiency.

[0091] In some embodiments of this application, reference is made to Figure 6 The prepositioning structure 9 may include a first flange 91, which is perpendicular to the height direction of the partition 4. The first flange 91 is located below the refrigerant radiator 82 and is used to support the refrigerant radiator 82.

[0092] The pre-positioning structure 9 may include a second flange 92. (See reference) Figure 6 Two second flanges 92 are arranged at intervals along the length direction of the first flange 91. The two second flanges 92 extend along the height direction of the partition 4, and the two second flanges 92 and the first flange 91 enclose each other to form a receiving part.

[0093] At least a portion of the refrigerant radiator 82 is located in the receiving section, and the prepositioning structure 9 can effectively support and position the refrigerant radiator 82, facilitating the installation and disassembly of the refrigerant radiator 82 and improving the convenience of maintenance and replacement.

[0094] refer to Figure 5 , Figure 6 After the refrigerant radiator 82 is installed into the receiving part, it will fall naturally due to gravity and contact the first flange 91 at the bottom. Therefore, the top does not need to be limited. After being positioned by the two second flanges 92 and the first flange 91, the positional accuracy of the refrigerant radiator 82 can be ensured. This ensures that the first mounting hole 821 and the third through hole 811 can be accurately located when the module radiator 81 and the refrigerant radiator 82 are fixed.

[0095] like Figure 7 As shown, in some embodiments of this application, the refrigerant radiator 82 may include a heat dissipation substrate 822, which is used to conduct heat.

[0096] The heat dissipation substrate 822 can be made of materials with excellent thermal conductivity, such as aluminum or copper. The heat dissipation substrate 822 made of aluminum or copper can quickly conduct the heat generated by the heat-generating module 71, improve the heat dissipation efficiency of the refrigerant radiator 82, ensure that the heat-generating module 71 operates at a suitable temperature, and ensure the stable operation of the electronic control board 52.

[0097] Continue to refer to Figure 7 The refrigerant radiator 82 may include a cooling pipe 823 for supplying refrigerant. The cooling pipe 823 is embedded in the heat dissipation substrate 822, allowing the refrigerant to directly absorb the heat transferred by the heat dissipation substrate 822 and carry it away, thereby achieving efficient heat exchange, enhancing the heat dissipation capacity of the refrigerant radiator 82, and effectively reducing the temperature of the heat-generating module 71.

[0098] The cooling pipe 823 has a refrigerant flow channel for refrigerant flow. The refrigerant flowing into the refrigerant circuit in the refrigerant flow channel absorbs heat and removes heat.

[0099] In this embodiment, one end of the cooling pipe 823 can be connected to the throttling device of the outdoor unit of the air conditioner through a pipe, and the other end of the cooling pipe 823 is connected to the low-pressure gas pipe of the outdoor unit of the air conditioner through a pipe.

[0100] It is understood that one end of the refrigerant pipe in the refrigerant circuit can serve as the cooling pipe 823. That is to say, the cooling pipe 823 in this application can be directly connected to and formed by the refrigerant pipe in the refrigerant circuit.

[0101] Of course, the cooling pipe 823 of this application can also be a pipe of similar material and shape to the refrigerant pipe. The refrigerant pipe is connected to the cooling pipe 823, so that the refrigerant in the refrigerant pipe can enter the cooling pipe 823 and use its own cooling capacity to dissipate heat. There is no need to set up a separate refrigerant supply system, but to directly use the refrigerant circuit of the air conditioner.

[0102] In some embodiments of this application, the heat dissipation module 71 and / or part of the module heat sink 81 are provided with openings 621.

[0103] In this embodiment, the heating module 71 includes a first heating module and a second heating module, and the opening 621 corresponds to the first opening and the second opening of the heating module 71. The first heating module passes through the first opening and is in contact with the module heat sink 81, while a portion of the module heat sink 81 passes through the second opening and is in contact with the second heating module.

[0104] In some embodiments of this application, two second flanges 92 are located opposite each other on both sides of the refrigerant radiator 82, and the single-sided gap between the first flange 91 and the refrigerant radiator 82 is a, where 0mm < a ≤ 0.5mm.

[0105] The first flange 91 supports the refrigerant radiator 82 from below, and the second flange 92 limits the width of the refrigerant radiator 82 on both sides.

[0106] In this embodiment, the single-sided gap 'a' is set within a reasonable range of 0~0.5mm. 'a' ≤ 0.5mm ensures the positional accuracy of the refrigerant radiator on the partition. 'a' > 0mm allows the refrigerant radiator to fall smoothly onto the first flange under gravity during installation, automatically, quickly, and accurately aligning with the corresponding through holes and mounting holes, thus improving installation efficiency and reliability.

[0107] In some embodiments of this application, two second flanges 92 are located opposite each other on both sides of the refrigerant radiator 82, and the single-sided gap between the first flange 91 and the refrigerant radiator 82 is a, 0mm < a, a ≤ 0.5mm.

[0108] The single-sided gap 'a' between the first flange 91 and the refrigerant radiator 82 should not be too large. If it is too large, the positioning accuracy of the refrigerant radiator 82 in the lateral direction will be reduced, making it impossible to fix it accurately in the preset position. As a result, the refrigerant radiator 82 may wobble left and right or shift its position during installation, making it difficult to align with the module radiator 81 or other components, increasing the installation difficulty and time cost.

[0109] To improve positioning accuracy, the single-sided gap 'a' is set to be no greater than the first parameter value, which can be any value between 0.4mm and 0.5mm. A suitable specific parameter should be selected during the design process. For example, if the first parameter value is 0.5mm, and the single-sided gap 'a' is ≤ 0.5mm, the positional accuracy of the refrigerant radiator on the partition is ensured, improving installation efficiency and reliability. Specifically, when 'a' = 0.5mm, the first fastener 101 can pass through the third through hole and connect to the first mounting hole in one go, achieving a fixed connection between the module radiator and the refrigerant radiator.

[0110] When the single-sided gap 'a' is greater than 0.5mm, the maximum amount of wobble of the refrigerant radiator will exceed the maximum compensable range when the third through hole and the first mounting hole are aligned at once. This will cause the third through hole and the first mounting hole to fail to align automatically, requiring manual alignment and reducing assembly efficiency.

[0111] The single-sided gap 'a' must not be less than 0mm. If the single-sided gap 'a' is less than or equal to 0mm, the gap fit between the refrigerant radiator and the pre-positioning structure cannot be guaranteed. In this case, the refrigerant radiator cannot naturally adhere to the first flange under the action of gravity, causing the pre-positioning of the pre-positioning structure to become an interference fit, resulting in assembly difficulties, inaccurate positioning, and damage to the second flange, thus affecting the pre-positioning function.

[0112] In some embodiments of this application, the partition 4 is provided with a second mounting hole 43, and the refrigerant radiator 82 is provided with a fourth through hole 824 for the second fastener 102 to pass through. The first fastener 101 and the second fastener 102 can be screws.

[0113] When the refrigerant radiator 82 is located on the prepositioning structure 9, the second mounting hole 43 is aligned with the fourth through hole 824, and the second fastener 102 passes through the fourth through hole 824 and is connected to the second mounting hole 43.

[0114] In this embodiment, the refrigerant radiator 82 is fixed to the partition 4 using a second fastener, making the connection between the refrigerant radiator 82 and the partition 4 more secure. This prevents the refrigerant radiator 82 from loosening due to vibration or other reasons, and further improves the positioning accuracy of the refrigerant radiator 82. Simultaneously, the pre-positioning structure 9 allows for convenient and quick fixing of the refrigerant radiator 82, improving the installation efficiency of the refrigerant radiator 82.

[0115] When assembling the electrical control box assembly, after positioning the refrigerant radiator 82 on the partition plate 4, the cooling pipe 823 is welded first to avoid deformation of the cooling pipe 823, improve production efficiency, ensure the fit between the refrigerant radiator 82 and the module radiator 81, and improve heat dissipation performance.

[0116] In some embodiments of this application, reference is made to Figure 11The top of the partition 4 is provided with a positioning flange 41 extending toward the fan cavity 51. In this embodiment, the plane of the positioning flange 41 is perpendicular to the height direction of the partition 4.

[0117] Continue to refer to Figure 11 The positioning flange 41 is provided with at least one positioning part 42, and the top of the outer shell 61 is provided with at least one hook 612. The hook 612 is adapted to be connected in the positioning part 42 to position the outer shell 61 on the partition 4.

[0118] In this embodiment, by setting the positioning flange 41 and the positioning part 42, an accurate initial positioning position is provided for the outer shell 61. During installation, the outer shell 61 can be first hung into the positioning part 42, thereby freeing the operator's hands and facilitating subsequent installation and fixing, greatly improving the convenience of installation. At the same time, the positioning part 42 is adapted to connect with the hook 612, which can perform preliminary positioning of the outer shell 61, ensuring its accurate position on the partition 4, and improving installation efficiency.

[0119] In some embodiments of this application, the hook 612 may include a support portion 6121, which is connected to the housing 61 to provide stable support for the initial positioning of the housing 61.

[0120] The hook 612 may include a guide portion 6122. (See reference) Figure 12 The top end of the guide part 6122 is connected to the support part 6121, and the bottom end of the guide part 6122 is a free end.

[0121] The guide section 6122 extends obliquely from top to bottom in a direction away from the partition 4.

[0122] In this embodiment, by providing a guide portion 6122 that extends obliquely from top to bottom away from the partition 4, the hook 612 can be inserted into the positioning portion 42 more smoothly during installation, reducing installation resistance and improving the convenience and efficiency of installation.

[0123] In some embodiments of this application, the positioning part 42 has positioning edges 421 on opposite sides, and the single-sided gap between the positioning edge 421 and the hook 612 is b, where 0mm < b ≤ 0.2mm.

[0124] In this embodiment, the single-sided gap b between the positioning edges 421 on both sides of the positioning part 42 and the hook 612 is set to 0~0.2mm, balancing assembly tolerance and positioning accuracy. When b≤0.2mm, the positioning accuracy of the hook 612 can be improved, ensuring the fitting accuracy between the hook 612 and the positioning part 42, avoiding shaking or displacement of the outer shell 61 during subsequent fixing, and effectively improving the installation accuracy and stability of the outer shell 61 on the partition 4. When b>0mm, the hook 612 and the positioning part 42 are fitted with a clearance, making it convenient for the hook 612 to be inserted into the positioning part 42.

[0125] In some embodiments of this application, the positioning part 42 has positioning edges 421 on opposite sides, and the single-sided gap between the positioning edge 421 and the hook 612 is b, where 0mm < b and b ≤ 0.2mm.

[0126] The single-sided gap b between the positioning edge 421 and the hook 612 should not be too large. If it is too large, the positioning accuracy of the hook 612 in the lateral direction will be reduced, and it will not be able to be accurately fixed in the preset position. As a result, the outer shell 61 may wobble left and right or shift its position during installation, making it difficult to align with other components, increasing the difficulty of installation and time cost.

[0127] To improve positioning accuracy, the single-sided gap b is set to no greater than the second parameter value, which can be any value between 0.18mm and 0.2mm. A suitable specific parameter should be selected during the design process. For example, a second parameter value of 0.2mm (b=0.2mm) can ensure a certain degree of precise fit between the hook 612 and the positioning edge 421, improving the positioning accuracy and stability of the outer shell 61 on the partition 4.

[0128] If the single-sided gap b is greater than 0.2mm, it will cause the positioning accuracy of the outer shell 61 on the partition 4 to be lost, which will make it difficult to align the subsequent fixed connection between the outer shell 61 and the partition 4 and increase the assembly time.

[0129] When the single-sided gap b≤0mm, it is impossible to guarantee the gap fit between the hook 612 and the positioning part 42. When the hook 612 is inserted into the positioning part 421, external force is required to force the hook 612 in, which may damage the hook 612 or the positioning flange 41 and increase the assembly difficulty.

[0130] In some embodiments of this application, the partition 4 is provided with at least one third mounting hole 44, and the outer casing 61 is provided with at least one fifth through hole 614. When the hook 612 is adapted to be connected in the positioning part 42, the fifth through hole 614 is aligned with the third mounting hole 44, and the third fastener passes through the fifth through hole 614 and is connected to the third mounting hole 44.

[0131] In this embodiment, by using the cooperation of the third mounting hole 44 and the fifth through hole 614, the third fastener can be used to firmly fix the outer shell 61 onto the partition 4, thereby improving the installation stability of the outer shell 61 and ensuring the structural stability of the electrical control box assembly.

[0132] In some embodiments of this application, reference is made to Figure 12 , Figure 13 The outer casing 61 is provided with at least one slot 613, and the box body 62 is provided with at least one plug-in part 623. The plug-in part 623 is adapted to be connected in the slot 613 to position the box body 62 on the outer casing 61.

[0133] In this embodiment, the slot 613 on the outer shell 61 is adapted to and connected to the plug-in part 623 on the box body 62, which can quickly and accurately position the box body 62 on the outer shell 61, improve the installation efficiency of the box body 62, reduce the installation time, and facilitate the subsequent fixing of the box body 62 and the outer shell 61.

[0134] refer to Figure 14 In some embodiments of this application, the card slot 613 may include a first sidewall 6131 disposed opposite to each other. The first sidewall 6131 is located on both sides of the insertion portion 623.

[0135] The slot 613 may include a bottom wall 6132, which abuts against the insertion portion 623. (See reference) Figure 14 The two first sidewalls 6131 are respectively connected to the two ends of the bottom wall 6132 through guide sidewalls 6133.

[0136] Continue to refer to Figure 14 The gap between the two guide sidewalls 6133 is set to decrease from top to bottom.

[0137] In this embodiment, by setting the aforementioned guide sidewall 6133, the insertion part 623 of the box 62 can be guided smoothly into the slot 613, reducing the time and effort required to insert the insertion part 623, allowing the operator to quickly complete the insertion operation, thereby improving the overall assembly efficiency.

[0138] In some embodiments of this application, the insertion part 623 and the guide sidewall 6133 have a minimum single-sided gap c, 0mm < c ≤ 0.2mm.

[0139] In this embodiment, the minimum single-sided gap c between the insertion part 623 and the guide sidewall is set to 0~0.2mm, which achieves an optimal balance between assemblability and positioning stability. When c≤0.2mm, high-precision positioning between the insertion part and the slot can be achieved. This high-precision fit ensures extremely high positional accuracy of the box body on the outer shell, thereby guaranteeing the assembly accuracy of the entire electrical control box assembly. When c>0mm, the insertion part 623 and the slot 613 are fitted with a clearance, facilitating the insertion part 623 to be inserted into the slot 613 and abut against the bottom wall 6132.

[0140] The minimum single-sided gap c should not be too large. If it is too large, the insertion part 623 may wobble left and right or shift position after being inserted into the slot 613, making it impossible to accurately fix it in the preset position. To improve the positioning accuracy of the box 62, the minimum single-sided gap c is set to no greater than the third parameter value, which can be any value between 0.18mm and 0.2mm. A suitable specific parameter should be selected during the design process. For example, a third parameter value of 0.2mm (c=0.2mm) can improve the assembly efficiency of the box 62.

[0141] When the single-sided gap c > 0.2mm, the positioning accuracy of the box 62 on the outer shell 61 will be lost, which will make it difficult to align the box 62 and the outer shell 61 in the subsequent fixed connection, and increase the assembly time.

[0142] When the single-sided gap c≤0mm, it is impossible to guarantee the bottom clearance fit between the plug part 623 and the guide side wall 6133. External force is required to force the plug part 623 to abut against the bottom wall 6132, which may damage the plug part 623 or the slot 613 and increase the assembly difficulty.

[0143] It should be noted that the minimum single-sided gap c is the single-sided gap between the insertion part 623 and the bottom end of the guide side wall 6133.

[0144] In this embodiment, when assembling the electrical control box assembly, the refrigerant radiator 82 is first placed on the prepositioning structure 9 and fixed to the partition 4 by two second fasteners 102. After the refrigerant radiator is fixed, the cooling pipe is welded. At this time, the electrical control box 6 and the electrical control board 7 are not installed, which can effectively avoid burning the electrical control board and the box body 62 and other materials during the welding of the cooling pipe.

[0145] After the cooling pipes are welded, the module heat sink 81 is fixed to the housing 62 with multiple screws, and then the control board 7 is installed inside the housing 62 to form a whole. The heating module 71 and the module heat sink 81 can be fixed together using screws.

[0146] The box 62 containing the electronic control board 7 is positioned on the outer shell 61 through multiple plug-in parts 623, forming an electronic control box assembly with the outer shell 61.

[0147] The electrical box assembly is first hung onto the positioning part 41 at the top of the partition 4 using the three hooks 612 on the top, and then secured to the partition 4 using multiple third fasteners. Finally, the module heat sink and the refrigerant heat sink are secured together using three first fasteners 10. Assembly is complete.

[0148] When repairing the control board, the box containing the control board 7 can be removed directly by removing the three first fasteners 101 for repair.

[0149] Of course, in some other embodiments, the housing 62 containing the control board 7 is positioned on the outer shell 61 by two lower plug-in portions 623 and is joined to the outer shell 61 by two upper screws to form an electronic control box assembly.
