Abstract

This application provides an electrical control box structure and an air conditioner. The electrical control box structure includes an electrical control body and a wiring body. The electrical control body has a heat exchanger and a terminal block on the same side, with the terminal block adjacent to the heat exchanger. The wiring body is adjacent to the heat exchanger and has a wire-holding groove for the wire harness connected to the terminal block to pass through. In this application, the wire harness connected to the terminal block is housed in the wire-holding groove of the wiring body, fixing the wire harness near the heat exchanger and limiting the distance between the wire harness and the heat exchanger to a safe distance to isolate them. At this time, the wire harness does not directly contact the heat exchanger, reducing interference and friction between the wire harness and the heat exchanger due to machine vibration.

Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to an electrical control box structure and an air conditioner. Background Technology

[0002] The outdoor unit of an air conditioner integrates key components such as an electrical control box, refrigerant pipes, a motor, and sensors, which are connected by cables. For example, the motor cable connects the electrical control box to the motor, so that the motor is powered through the electrical control box; the sensor cable connects the electrical control box to a sensor used to monitor the refrigerant pipes, so that it sends signals back to the electrical control box.

[0003] In some models of related technologies, the cables are directly exposed and only randomly fixed inside the machine body with a few wire ties. This makes it easy for cables near the refrigerant pipes to come into direct contact with the refrigerant pipes. During the vibration of the machine body, interference and friction occur frequently, causing wear on the cable insulation layer. This may lead to leakage and short circuits, posing a safety hazard. Utility Model Content

[0004] This application provides an electrical control box structure and an air conditioner to solve the technical problem in some related models where cables are directly exposed and only randomly fixed inside the unit with a few wire ties.

[0018] The electrical control box structure also includes mounting screws, which pass through the mounting holes and are threadedly connected to the heat exchanger via the connecting screw holes.

[0019] In some embodiments, the bottom wall of the cable tray is further provided with a recessed groove, which communicates with the mounting hole.

[0020] In some embodiments, the wiring body is provided with a positioning part on the side near the heat exchanger, and the heat exchanger is provided with a corresponding mating part, the positioning part and the mating part being positioned together.

[0021] In some embodiments, the extending direction of the wire slot is the same as the extending direction of the heat exchanger; and / or,

[0022] The extension direction of the wiring body is the same as the extension direction of the heat exchanger.

[0023] In some embodiments, the slot of the cable tray is located on the side of the cable carrier body facing away from the heat exchanger; and / or,

[0024] The wiring body is installed on the heat exchanger and located on the side of the heat exchanger opposite to the electrical control body.

[0025] In some embodiments, the wire-locking channel is open at both ends in its extending direction; and / or,

[0026] The wiring body also has at least one connection port, which connects the outside to the wire clamping channel and the outside. The connection port is located in the middle of the wire clamping channel and is offset from the heat exchanger.

[0027] In some embodiments, a sensor is provided at one end of the heat exchanger in the extending direction, and the extending direction of the wire clamping channel is the same as the extending direction of the heat exchanger;

[0028] The wiring terminal includes a first terminal, which is located near the end of the heat exchanger away from the sensor. A signal line is connected between the first terminal and the sensor, and the signal line passes through the wire slot.

[0029] In some embodiments, two wire-locking channels are provided, and the two wire-locking channels are isolated from each other;

[0030] The wiring terminal also includes a second terminal. The second terminal, the heat exchanger, and the first terminal are located on the same side of the electrical control body. The second terminal is connected to a motor cable. The motor cable and the signal line are respectively passed through the two cable trays.

[0031] In some embodiments, the first terminal and the second terminal are located on opposite sides of the heat exchanger.

In this way, on the one hand, because the wire harness is fixed in the wire-holding groove, the distance between the wire harness and the heat exchanger is limited to a safe distance, isolating the wire harness from the heat exchanger. At this time, the wire harness does not directly contact the heat exchanger, reducing the possibility of interference and friction between the wire harness and the heat exchanger due to machine vibration.

[0058] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0059] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0060] In related technologies, wiring terminals are located near the refrigerant pipes. However, in some models, the cables connected to these terminals are directly exposed, only randomly secured inside the unit with a few wire bundles. This results in the cables easily becoming bent and tangled in a disordered state. When the outdoor unit of the air conditioner is operating, the compressor vibration and fan rotation cause the unit to vibrate. These disordered cables are prone to direct contact with the refrigerant pipes, and frequent interference and friction occur during the unit's vibration, leading to wear on the cable insulation. Since the refrigerant pipes are made of conductive metal, this can cause leakage and short circuits, posing a safety hazard.

[0061] Therefore, this application provides an electrical control box structure and an air conditioner that can reduce the bending and tangling of the wiring harness, making the wiring harness layout relatively clear, and allowing for quick location of the wiring during subsequent maintenance, thus improving maintenance convenience. At the same time, the wiring harness is fixed by the wire clamping groove and isolated from the heat exchanger, reducing the possibility of the wiring harness directly contacting the refrigerant pipe and causing interference and friction, thereby reducing the occurrence of leakage, short circuit or wire harness corrosion by condensate, reducing safety hazards and improving safety performance.

[0062] Please see Figures 1 to 4 The electrical control box structure provided in this application includes an electrical control body 1 and a wiring body 2. The electrical control body 1 has a heat exchanger 11 and a wiring terminal 12 on the same side, and the wiring terminal 12 is adjacent to the heat exchanger 11. The wiring body 2 is adjacent to the heat exchanger 11 and has a wire-holding channel 2a, which is used for the wire harness connected to the wiring terminal 12 to pass through.

[0063] In this application, the wire harness connected to the terminal block 12 is housed in the wire-holding groove 2a of the wiring body 2, so that the wire harness near the heat exchanger 11 is fixed by the wire-holding groove 2a. In this way, on the one hand, since the wire harness is fixed in the wire-holding groove 2a, the distance between the wire harness and the heat exchanger 11 is limited to a safe distance to isolate them from the heat exchanger 11. At this time, the wire harness does not directly contact the heat exchanger 11, reducing the possibility of interference and friction between the wire harness and the heat exchanger 11 due to machine vibration. This makes the insulation layer of the wire harness less likely to be worn by the heat exchanger 11, reducing safety hazards and improving safety performance.

[0064] On the other hand, after the wiring body 2 is pre-installed in the heat exchanger 11, the wire harness can be directly passed through the wire clamping channel 2a without repeated position adjustments, reducing the problems of wire harness tangling and crossing, making the wire harness layout neat and improving the assembly efficiency of the production line; at the same time, since the wire harness is centrally constrained by the wire clamping channel 2a, the layout is clear, and the target wire harness can be quickly located during maintenance, improving the convenience of maintenance.

[0065] It should be noted that the electronic control unit 1 is the core component for realizing electronic control functions, and is the core part for power distribution, signal processing, and motor control. The electronic control unit 1 typically includes a bracket, main control board, power devices, protection devices, and auxiliary functional components. The heat exchanger 11 is usually directly mounted on the main control board and is used to dissipate heat from the electronic control unit 1.

[0066] In one embodiment, please refer to Figures 2 to 4 There are at least two wire-locking channels 2a, and the at least two wire-locking channels 2a are isolated from each other and parallel to each other.

[0067] In this embodiment, at least two cable trays 2a are provided, allowing the wiring harnesses connecting different components to be distributed in different cable trays 2a, making the wiring harnesses more organized and facilitating maintenance of different types of cables by operators. Furthermore, different cables can be distributed in different cable trays 2a according to their harness type. Specifically, cables can be distributed in different cable trays 2a according to strong and weak current; for example, the motor cable 5 connecting the fan and the signal line 4 connecting the sensor 3 can be distributed in different cable trays 2a. Since the cable trays 2a are isolated from each other, signal interference can be reduced, ensuring the stability of power transmission and signal feedback. Simultaneously, the parallel arrangement of the cable trays 2a ensures that they are adjacent to but do not overlap with the heat exchanger 11, reducing the overall thickness or width of the electrical control box.

[0068] Furthermore, it should be understood that two or more cable clamping channels 2a can be provided. Specifically, in this solution, two mutually isolated cable clamping channels 2a are provided according to the strong and weak current wire harnesses connected to the terminal 12 adjacent to the heat exchanger 11, one for clamping strong current cables and the other for clamping weak current cables.

[0069] It should be noted that the wiring body 2 can be mounted on the electrical control body 1 and adjacent to the heat exchanger 11. Alternatively, the wiring body 2 can be directly mounted on the heat exchanger 11. In one embodiment, the heat exchanger 11 has a mounting side 111 offset from the electrical control body 1, and the wiring body 2 is mounted on the mounting side 111; the cable tray 2a is arranged in a direction parallel to the mounting side 111.

[0070] In this embodiment, the wiring body 2 is positioned on the mounting side 111 of the heat exchanger 11, offset from the mounting side 111 of the electrical control body 1. The arrangement direction of the multiple wire-clamping channels 2a is parallel to the mounting side 111 and offset, avoiding the need for additional space due to their perpendicularity to the mounting side 111. This allows the wire-clamping channels 2a to be adjacent to the heat exchanger 11 without overlapping, compressing the overall thickness or width of the electrical control box. Simultaneously, it ensures that the wire harnesses within each wire-clamping channel 2a are equidistant from the heat exchanger 11, enabling uniform heat exchange between the wire harnesses and the heat exchanger 11 even in extreme environments.

[0071] In one embodiment, please refer to Figure 3 and Figure 4 The cable routing body 2 is provided with a cable routing groove 2b, and at least one partition 21 is provided in the cable routing groove 2b. The extension direction of the at least one partition 21 is the same as the extension direction of the cable routing groove 2b, and the cable routing groove 2b is divided into at least two cable clamping channels 2a.

[0072] In this embodiment, the partition 21 divides the routing grooves into cable-clamping channels 2a with the same extension direction, enabling directional arrangement of the wire harness. This reduces the possibility of cables crossing and tangling outside the cable-clamping channels 2a, further improving the orderliness and regularity of the cables, making cable ownership relatively clear, and allowing for quick location of the target cable during maintenance. Simultaneously, when the wire harness has a unified routing, the openings on the control box are consistent, reducing the number of bends at the cable exit point and facilitating the design of a uniform sealing structure.

[0073] In one embodiment, please refer to Figure 3 and Figure 5 The slot end of the wire clamping channel 2a is provided with a wire clamping buckle 22. One end of the wire clamping buckle 22 is connected to the side wall of the wire clamping channel 2a, and the other end is spaced apart from the side wall opposite to the wire clamping channel 2a.

[0074] In this embodiment, one end of the wire clamp 22 is connected to the side wall of the wire clamping channel 2a, and the other end is spaced apart from the side wall opposite to the wire clamping channel 2a, forming an opening. Thus, the wire clamp 22 forms an elastic arm, and its free end has a certain deformation capability along the inside and outside of the groove when subjected to a certain external force. When the wire harness enters the wire clamping channel 2a through the opening, it is clamped by the wire clamp 22. Therefore, when the outdoor unit of the air conditioner vibrates, the wire clamp 22 stably presses the wire harness into the wire clamping channel 2a, locking the cable and reducing the vibration of the wire harness relative to the wiring body 2, further reducing interference and friction. Furthermore, the elastic characteristics of the wire clamp 22 ensure that it can adapt to different cable outer diameter variations. It should be noted that in this solution, the wire clamp 22 is integrally formed with the wiring body 2; and the elastic deformation capability of the wire clamp 22 must be sufficient to overcome the displacement of the wire harness when the unit vibrates.

[0075] In one embodiment, multiple wire clamps 22 are provided, and the multiple wire clamps 22 are arranged at intervals along the extension direction of the wire clamping channel 2a.

[0076] In this embodiment, after the cable is threaded through the cable clamping channel 2a, multiple clamping clips 22 work together to fix the cable in the cavity, forming a multi-point continuous fixation, which improves the locking ability of the cable and ensures that the cable is always in the channel. In addition, the spaced clamping clips 22 can disperse the fixing force, avoid stress concentration on the cable caused by single-point pressing, and extend the service life of the cable.

[0077] In one embodiment, please refer to Figure 4 The plurality of wire clamps 22 include at least one first wire clamp 221 and at least one second wire clamp 222, with the first wire clamp 221 and the second wire clamp 222 located on opposite side walls of the wire clamping channel 2a, respectively.

[0078] In this embodiment, wire clamps 22 are respectively connected to two opposite sidewalls of the wire clamping channel 2a. When the cable is clamped inside the wire clamp 22, the first wire clamp 221 and the second wire clamp 222 can collectively intercept the opening, thereby preventing the cable from detaching from the wire clamping channel 2a. Furthermore, the opposing first wire clamps 221 and the second wire clamp 222 can further disperse the fixing force. It should be noted that in this solution, the number of first wire clamps 221 and the number of second wire clamps 222 are different. Specifically, in one embodiment, the number of first wire clamps 221 is greater than the number of second wire clamps 222, so that the cable can be fed into the opening corresponding to the fewer second wire clamps 222, ensuring the cable clamping ability while also improving the convenience of cable assembly.

[0079] In one embodiment, please refer to Figure 5 and Figure 6 The bottom wall of the wire clamping channel 2a is provided with a clearance groove 2c opposite to the wire clamping buckle 22.

[0080] In this embodiment, the corresponding arrangement of the clearance groove 2c and the clamping clip 22 allows the clamping structure of the clamping clip 22 to better conform to the cable profile. For example, when the clamping clip 22 presses down to fix the cable, its force-bearing end can be embedded in the clearance groove 2c, and it will not be unable to be fully clamped due to the obstruction of the bottom wall of the channel. This close-fitting fixing can reduce the radial movement space of the cable in the channel. Even if the outdoor unit generates continuous vibration during operation, the cable is unlikely to come out from the fit gap between the clamping clip 22 and the channel, solving the contradiction of traditional fixing methods where the clip is too loose and easy to fall off, or too tight and difficult to assemble, thus ensuring the reliability of cable fixing.

[0081] Furthermore, the clearance groove 2c, with its reserved space and the elastic structure of the wire clamp 22, can accommodate cables of different diameters. The clearance groove 2c is a recessed structure on the bottom wall of the channel, which increases the airflow path inside the channel. The power cables inside the outdoor unit's electrical control box generate heat during operation; the gap created by the clearance groove 2c allows airflow to pass more smoothly over the cable surface, reducing heat accumulation at the cable fixing points. Simultaneously, the clearance groove 2c reduces the contact area between the wire clamp 22 and the bottom wall of the channel, minimizing the wire clamp 22's obstruction of the channel's heat dissipation, indirectly improving the overall heat dissipation efficiency of the electrical control box and preventing accelerated aging of the cable insulation layer due to high temperatures. Specifically, in this solution, the clearance groove 2c penetrates the bottom wall of the wire clamping channel 2a.

[0082] In one embodiment, the wiring body 2 is detachably connected to the heat exchanger 11.

[0083] In this embodiment, the fins of the heat exchanger 11 are prone to dust and oil accumulation, requiring regular cleaning. Furthermore, long-term operation may lead to pipe leaks and other malfunctions, necessitating disassembly and repair. If the cable tray 2 is fixedly connected to the heat exchanger 11, maintenance of the heat exchanger 11 requires cutting or forcibly pulling the cable, which is not only cumbersome but also prone to causing cable insulation wear and loosening of terminals. The detachable connection allows for quick separation of the cable tray 2 from the heat exchanger 11 before maintenance, completely freeing the heat exchanger 11 from cable constraints, allowing for direct removal for cleaning or repair. Simultaneously, the cable within the cable tray 2a remains fixed, eliminating the need for disassembly and preventing secondary damage to the electrical control cables during maintenance, significantly reducing maintenance time. Moreover, when either the heat exchanger 11 or the cable tray 2 experiences a separate fault, the detachable connection enables targeted replacement, reducing unnecessary component waste and lowering maintenance costs.

[0084] It should be noted that the wiring body 2 and the heat exchanger 11 can be connected by snap-fit, tenon and mortise or other means.

[0085] In one embodiment, please refer to Figures 4 to 7 The bottom wall of the cable tray 2a is provided with a mounting hole 2d, and the heat exchanger 11 is provided with a connecting screw hole 112a corresponding to the mounting hole 2d. The electrical control box structure also includes mounting screws, which pass through the mounting hole 2d and are threadedly connected to the heat exchanger 11 via the connecting screw hole 112a.

[0086] In this embodiment, the wiring body 2 and the heat exchanger 11 are detachably connected by screws, and rigidly fixed by mechanical locking of the screw pair. The connection strength is far superior to that of clips and tenons, adapting to the harsh operating conditions and long-term stable operation requirements of the outdoor unit, and providing a stable connection for the wiring body 2 even in strong vibration environments. It should be noted that in this design, multiple sets of mounting holes 2d, connecting screw holes 112a, and mounting screws are provided to further improve the installation stability of the wiring body 2. Specifically, in this design, three sets of mounting holes 2d, connecting screw holes 112a, and mounting screws are provided.

[0087] In one embodiment, the bottom wall of the cable slot 2a is further provided with a recessed groove 2e, which is connected to the mounting hole 2d.

[0088] In this embodiment, the screw head is located within the recessed groove 2e, concealing the screw head and preventing interference between the cable and the screw head. This ensures the cable's insulation layer is not scratched by the protruding screw head. It should be understood that the recessed groove 2e is offset from the mounting position of the wire clamp 22 to prevent interference between the screw head and the clamping structure of the wire clamp 22, ensuring the wire clamp 22 can properly clamp the cable.

[0089] In one embodiment, the wiring body 2 is provided with a positioning part 23 on the side near the heat exchanger 11, and the heat exchanger 11 is provided with a corresponding mating part 114. The positioning part 23 and the mating part 114 are positioned together.

[0090] In this embodiment, after the positioning part 23 on the wiring body 2 mates with the mating part 114 on the heat exchanger 11, the wiring body 2 automatically aligns with the heat exchanger 11, thereby achieving alignment between the mounting hole 2d and the connecting screw hole 112a, improving the convenience of mounting screw assembly. Simultaneously, the rigid connection between the positioning part 23 and the mating part 114 ensures the fixed position of the wiring body 2 on the heat exchanger 11, preventing displacement caused by manual adjustment during installation. It should be noted that one of the positioning part 23 and the mating part 114 can be configured as a positioning block, positioning plate, or other form, while the other is configured as a corresponding matching hole. Specifically, in this solution, the positioning part 23 is the positioning post 231 on the side of the wiring body 2 closest to the heat exchanger 11, and the mating part 114 is the positioning hole 114a on the heat exchanger 11. In this embodiment, two sets of positioning holes 114a and positioning posts 231 are provided.

[0091] In one embodiment, the extension direction of the wire slot 2a is the same as the extension direction of the heat exchanger 11.

[0092] In this embodiment, the extension direction of the wire-holding channel 2a is consistent with the extension direction of the heat exchanger 11. At this time, the adjacent wire harness can run parallel to the heat exchanger 11 and be fixed by the wire-holding channel 2a. This allows the wire harness to effectively fall into the wire-holding channel 2a in the extension direction of the heat exchanger 11, further reducing the possibility of the wire harness contacting and interfering with the heat exchanger 11 in the extension direction. This reduces the risk of electric shock and other safety problems caused by the wire harness insulation layer wearing down and contacting the metal part of the heat exchanger 11, thus lowering safety hazards and improving safety performance. It also increases the heat exchange area between the wire harness and the heat exchanger 11, facilitating heat dissipation for high-power wire harnesses.

[0093] Furthermore, the parallel layout of the cable tray 2a and the heat exchanger 11 allows the wire harnesses adjacent to the heat exchanger 11 to extend naturally along the direction of the heat exchanger 11, reducing the bending and tangling of the wire harnesses, making the wire harness layout relatively clear, and allowing for quick location of the lines during subsequent maintenance, thus improving maintenance convenience; it can also shorten the laying length of the wire harnesses, saving material costs and reducing the difficulty of wiring during subsequent assembly, thereby improving assembly efficiency.

[0094] In one embodiment, the extension direction of the wiring body 2 is the same as the extension direction of the heat exchanger 11.

[0095] In this embodiment, the cable tray 2 and heat exchanger 11, designed to extend in the same direction, form a regular parallel layout. This makes full use of the unused space inside the electrical control box and avoids the cable tray 2 and heat exchanger 11 intersecting and occupying additional space, making the overall structure of the electrical control box more compact and suitable for the confined installation environment inside the equipment. It also increases the heat exchange area between the cable tray 2 and heat exchanger 11, improving the heat dissipation capacity for high-power cables.

[0096] In one embodiment, the slot of the cable tray 2a is located on the side of the cable body 2 facing away from the heat exchanger 11.

[0097] In this embodiment, since the slot of the cable clamping channel 2a is located on the back side of the heat exchanger 11, during assembly, the heat exchanger 11 is fixed in place first, then the cable routing body 2 is installed, and the slot of the cable clamping channel 2a is oriented towards the back of the heat exchanger 11. Finally, the cable is threaded through and fixed, which avoids mutual interference between the cable and the heat exchanger 11 during the installation process and improves assembly efficiency.

[0098] In one embodiment, the wiring body 2 is mounted on the heat exchanger 11 and located on the side of the heat exchanger 11 facing away from the electrical control body 1.

[0099] In this embodiment, the wiring body 2 is located on the back of the heat exchanger 11, which does not occupy additional space in the electrical control body 1 laterally, thus improving space utilization. Simultaneously, the high-frequency electromagnetic radiation generated by the main control board (especially the inverter module) during operation is blocked by the metal structure of the heat exchanger 11, reducing interference to the signal lines 4 within the wiring body 2. Furthermore, compared to the dispersed arrangement of the heat exchanger 11 and wiring harness in related technologies, in this application, the wiring body 2 is directly installed on the back of the heat exchanger 11, allowing the heat dissipation area and wiring area to overlap but not interfere with each other. This eliminates the need for additional wiring space in the electrical control body 1 and does not affect the heat dissipation contact area of ​​the heat exchanger 11, resulting in a more compact layout of the electrical control body 1 and improved space utilization.

[0100] In one embodiment, the wire slot 2a is open at both ends in its extending direction.

[0101] In this embodiment, both ends of the cable tray 2a are open, facilitating the entry and exit of the cable harness through both ends of the cable tray 2a. Cables can be led out from either end of the tray without the need for pre-planning a fixed exit direction. During assembly, there is no need to distinguish between the entry and exit ends of the tray, reducing worker identification costs, minimizing rework due to reverse installation, and facilitating rapid cable threading. Simultaneously, this also allows the cable routing body 2 to hold cables at all points along the extension direction of the cable tray 2a, improving the utilization rate of the cable routing body 2.

[0102] In one embodiment, the wiring body 2 also has at least one connection port 2f, which connects the outside to the wire clamping channel 2a and the outside. The connection port 2f is located in the middle of the wire clamping channel 2a and is offset from the heat exchanger 11.

[0103] In this embodiment, the cable can also pass through the connecting port 2f in the middle of the cable tray 2b. The cable does not need to detour from both ends of the tray and can be directly led out through the connecting port 2f to connect to nearby components, solving the problem of cable detour, avoiding cable crossing and tangling, and saving cable length. It should be noted that the connecting port 2f is provided at intervals of two or more along the extension direction of the cable tray 2a. Specifically, in this solution, there are two connecting ports 2f at intervals along the extension direction of the cable tray 2a, which are respectively provided for the two motor cables 5 of the dual-fan external unit to pass through.

[0104] In one embodiment, please refer to Figure 1 and Figure 7 A sensor 3 is provided at one end of the heat exchanger 11 in the extension direction. The extension direction of the wire clamping channel 2a is the same as the extension direction of the heat exchanger 11. The wiring terminal 12 includes a first terminal 121. The first terminal 121 is adjacent to the end of the heat exchanger 11 away from the sensor 3. A signal line 4 is connected between the first terminal 121 and the sensor 3. The signal line 4 passes through the wire clamping channel 2a.

[0105] In this embodiment, sensor 3 is used to monitor the operating parameters of heat exchanger 11 and transmits the signal to the electronic control body 1 via signal line 4. Sensor 3 and the first terminal 121 of the signal line 4 correspond to the two ends of the heat exchanger 11 in the extending direction, so that the signal line 4 starts from sensor 3, passes through the entire cable clamping channel 2a, and connects to the first terminal 121. Thus, the main body of the signal line 4 is clamped within the cable clamping channel 2a, effectively preventing friction between the signal line 4 and the heat exchanger 11 and improving safety performance. Specifically, in this solution, the heat exchanger 11 has a slot on the side near the electronic control body 1, and sensor 3 is installed in the slot using screws.

[0106] In one embodiment, there are two wire-locking channels 2a, which are isolated from each other; the terminal block 12 also includes a second terminal 122, which, the heat exchanger 11 and the first terminal 121 are located on the same side of the electrical control body 1, and the second terminal 122 is connected to a motor cable 5, which and the signal line 4 are respectively passed through the two wire-locking channels 2a.

[0107] In this embodiment, the cables are distributed in different cable trays 2a according to their strength and weakness. Specifically, the motor cable 5 connecting the fan and the signal line 4 connecting the sensor 3 are distributed in different cable trays 2a. Since the cable trays 2a are isolated from each other, signal interference can be reduced, ensuring the stability of power transmission and signal feedback.

[0108] In one embodiment, the first terminal 121 and the second terminal 122 are located on opposite sides of the heat exchanger 11.

[0109] In this embodiment, the first terminal 121 and the second terminal 122 are distributed on opposite sides of the heat exchanger 11, so that the signal line 4 and the motor cable 5 are led from opposite sides of the cable tray 2a to the first terminal 121 and the second terminal 122 respectively, avoiding wire harness tangling and optimizing the wire harness layout. It should be noted that in this solution, there are two second terminals 122, which are respectively connected to the two motors of the dual-fan outdoor unit.

[0110] It should be noted that the heat exchanger 11 can be configured as a semiconductor heat exchange structure, an independent refrigerant pipe 113, or other forms. In another embodiment, please refer to... Figure 7 The heat exchanger 11 includes a heat exchange base 112 and a refrigerant pipe 113. The heat exchange base 112 is installed on the electrical control body 1 and has a channel for the refrigerant pipe 113 to pass through. The wiring body 2 is installed on the heat exchange base 112.

[0111] In this embodiment, the heat exchange base 112 serves as the mounting carrier for the wiring body 2, preventing damage to the refrigerant pipe 113 caused by the fixing structure of the wiring body 2 and ensuring the integrity of the refrigerant pipe 113. The structural characteristics of the heat exchange base 112 also ensure stable fixing of the wiring body 2, while simultaneously considering heat exchange efficiency, vibration damping, and cable protection, making it suitable for complex operating conditions in scenarios such as air conditioner outdoor units. Specifically, in this solution, both the connecting screw hole 112a and the positioning hole 114a are located on the heat exchange base 112. The heat exchange base 112 has thermal conductivity.

[0112] In one embodiment, please refer to Figure 8 The cable routing body 2 includes a base 24 and two baffles 25. The base 24 has a slot 24a that is engaged with the heat exchanger 11. The two baffles 25 are located on the same side of the base 24 and are staggered from the heat exchanger 11. The two baffles 25 are spaced apart and form a cable routing channel 2a.

[0113] In this embodiment, during assembly, the base 24 of the wiring body 2 is secured to the outside of the heat exchanger 11 via the slot 24a, allowing for quick positioning of the wiring body 2 and the heat exchanger 11 and improving assembly convenience. Simultaneously, the slot 24a increases the contact area between the wiring body 2 and the heat exchanger 11, enhancing the heat dissipation capacity for high-power wiring harnesses. It also reduces the weight of the wiring body 2, facilitating weight reduction.

[0114] Furthermore, this application also provides an air conditioner that includes the electrical control box structure as described above. The specific structure of this electrical control box is as described in the above embodiments. Since this air conditioner adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated upon here.

[0115] In one embodiment, please refer to Figure 9 The air conditioner also includes an outdoor unit housing 6, which has a partition 61 and a side panel 62 spaced apart, and the space between the partition 61 and the side panel 62 is used to accommodate the compressor 7; the electrical control body 1 of the electrical control box structure is located between the partition 61 and the side panel 62, and the electrical control body 1 is connected to the partition 61 and the side panel 62.

[0116] In this application, a chamber for accommodating the compressor is formed by the partition 61 and the side plate 62, and the electrical control box structure and the compressor are installed in the same chamber. This facilitates direct connection between the electrical control components on the electrical control box structure and the compressor 7, shortening the wiring length. Specifically, in this embodiment, the chamber for housing the compressor 7 and the electrical control box structure is also separated from the chamber for installing the fan by the partition 61. This prevents the fan airflow from directly impacting the compressor, causing local temperature fluctuations, and also prevents the high-temperature radiation of the compressor 7 from affecting the heat exchange effect of the condenser, making the refrigeration cycle more stable. Furthermore, it should be noted that in one embodiment, the electrical control body 1 is bolted to the partition 61 and the side plate 62. In this embodiment, the side plate 62 is the right side plate.
