[0049] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0050] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0051] Please see Figure 1 , Figure 1 This is a schematic diagram of the electrical control box 100 in one embodiment of this application. Figure 1 As shown, the electrical control box 100 may include an electrical control box body 1 and electrical control components (not shown). The electrical control box body 1 has an installation space 13, and the electrical control components are disposed within the installation space 13. The electrical control box body 1 is generally made of sheet metal, and the electrical control components disposed within the installation space 13 may typically include electrical control modules such as compressor modules, fan modules, capacitors, and common mode inductors.

[0052] like Figure 2 As shown, the electrical control box body 1 may include a front panel (not shown, disposed opposite to the back panel 11), a back panel 11, and a side panel 12. The front panel and the back panel 11 are disposed opposite each other with a gap, and the side panel 12 is connected to the front panel and the back panel 11, thereby forming an installation space 13. The side panel 12 may include a top panel 121 located above it. In other embodiments, the electrical control box body 1 may also include only the back panel 11 and the side panel 12.

[0053] Specifically, in Figure 1 In the design, the back panel 11 is rectangular, and there are three side panels 12. The three side panels 12 are respectively connected to the corresponding sides of the back panel 11, thus forming a cuboid electrical control box body 1. The length of the back panel 11 is the length of the electrical control box body 1, and the width of the back panel 11 is the width of the electrical control box body 1. The height of the side panels 12 perpendicular to the back panel 11 is the height of the electrical control box body 1.

[0054] In other embodiments, the back plate 11 and the front panel of the electrical control box body 1 can also be circular, trapezoidal, triangular, or other shapes. The side plate 12 is also arranged around the outer periphery of the back plate 11 to form electrical control box body 1 of other shapes. The shape of the electrical control box body 1 can be set as needed, and this application embodiment does not make specific limitations.

[0055] This application further optimizes the overall structure of the electronic control box 100 described above in the following aspects:

[0056] 1. Heat sink for dissipating heat from the electrical control box

[0057] In this embodiment, the electrical control box 100 may further include a heat sink 2, which is disposed on the electrical control box body 1 to dissipate heat for the electrical control box body 1 and its internal electrical control components.

[0058] The heat sink 2 can be made of a material with excellent heat transfer properties, such as aluminum or copper, in order to improve the heat dissipation efficiency of the heat sink 2.

[0059] like Figure 3 As shown, the heat sink 2 can be disposed on the outer side of the back plate 11. And as... Figure 4 , Figure 5 and Figure 6 As shown, the heat sink 2 may also have a boss 21, which passes through the slot 111 opened on the back plate 11 of the electrical control box body 1. In this way, part of the heat sink 2 can extend from the outside of the electrical control box body 1 to the inside of the electrical control box body 1, so as to improve the heat dissipation effect of the heat sink 2 on the electrical control box body 1 and its internal electrical control components.

[0060] In addition, the protrusion 21 of the heat sink 2 and the electrical control component located inside the electrical control box body 1 (i.e., inside the back plate 11) are spaced apart to avoid direct contact between the protrusion 21 and the electrical control component located inside the back plate 11, thereby preventing direct contact between the heat sink 2 and the electrical control component. This effectively prevents condensate from flowing from the heat sink 2 to the electrical control component, thus preventing short circuits in the electrical control component and improving the safety and reliability of the electrical control box 100.

[0061] The number of slots 111 and protrusions 21 can be equal, and their positions can correspond one-to-one. For example, the back plate 11 has three slots 111, and the heat sink 2 has three protrusions 21 at corresponding positions on the slots 111, so that the three protrusions 21 on the heat sink 2 can be respectively inserted into the corresponding slots 111. Of course, in other embodiments, the number of slots 111 may not be equal to the number of protrusions 21. For example, the number of slots 111 may be less than the number of protrusions 21, wherein at least two protrusions 21 can be inserted into the same slot 111.

[0062] The number of protrusions 21 is unlimited and can be set according to the actual situation, for example, 1, 2, 3, 6, 10, etc.

[0063] Correspondingly, the number of slots 111 is also unlimited, and can be set according to the actual situation, for example, 1, 2, 3, 6, 10, etc.

[0064] The heat sink 2 can be installed on the back plate 11. In this way, the heat sink 2 is mainly installed and positioned by the electrical control box body 1. This not only makes the structure compact and saves space, but also ensures a reliable position. It avoids the heat sink 3 from being easily deformed due to the heat sink 2 being installed and positioned by the heat sink 3, thus protecting the heat sink 3.

[0065] Specifically, the heat sink 2 can be fixedly installed on the back plate 11 using fasteners such as screws and rivets. The number of fasteners is not limited and can be set according to actual needs, for example, 2, 3, or 5. The fasteners in this application are designed to avoid gaps, preventing the diffusion of condensate at the fastener locations. The size of the fasteners is also not limited; for example, the fasteners can be M4*12 screws or M6*8 screws.

[0066] Please continue reading. Figure 3 The electrical control box 100 may also include a heat sink 3 connected to the heat sink 2, so as to provide cooling to the heat sink 2 through the heat sink 3. That is, the heat sink 3 dissipates heat from the electrical control box body 1 and the electrical control components inside the electrical control box body 1 through the heat sink 2.

[0067] Among them, such as Figure 7 As shown, the radiator 3 may include a heat exchange body, which may have multiple channels. These channels are divided into a first channel and a second channel, and the first channel can contact the second channel to facilitate heat exchange between the first refrigerant flow in the first channel and the second refrigerant flow in the second channel. This ensures that the radiator 3 has sufficient cooling capacity to dissipate heat from the electrical control box body 1 and its internal electrical control components. Both the first channel and the second channel can be microchannels.

[0068] Preferably, the extension direction of the first channel can be the same as that of the second channel to increase the contact area between the first channel and the second channel, thereby improving the heat exchange efficiency between the first channel and the second channel.

[0069] In this embodiment, the heat exchange body may include at least one first plate 31 and at least one second plate 31, wherein the first plate 31 has at least one first channel and the second plate 31 has at least one second channel. Both the first plate 31 and the second plate 31 can be collectively referred to as plate 31. In other embodiments, the heat exchange body may include at least one plate 31, and the multiple channels within each plate 31 may be divided into alternately arranged first channels and second channels.

[0070] Based on the function of plate 31, plate 31 can also be called a heat exchange tube.

[0071] The plate 31 can be a flat tube so that the heat sink 2 can be mounted on the plate 31. In other embodiments, the plate 31 can also be a carrier with other cross-sectional shapes, such as a cylinder, cuboid, cube, etc.

[0072] Please continue reading for more details. Figure 3 The radiator 3 can be set on the side of the heat sink 2 away from the back plate 11 in order to increase the contact area between the heat sink 2 and the radiator 3, thereby improving the heat exchange efficiency between the heat sink 2 and the radiator 3.

[0073] like Figure 8 As shown, the surface of the heat sink 2 away from the back plate 11 may have a groove 23 and / or a positioning rib 22, which are used to position the heat sink 3 through the groove 23 and / or the positioning rib 22, so as to better fix the heat sink 3 and fully ensure the heat exchange area between the heat sink 2 and the heat sink 3.

[0074] The number of grooves 23 is not limited; for example, it can be 1, 3, or 5.

[0075] Furthermore, the number of positioning ribs 22 is not limited, for example, it can be 1, 2 or 10. Preferably, two positioning ribs 22 can be provided on the surface of the heat dissipation plate 2 away from the back plate 11, and these two positioning ribs 22 are located on opposite sides of the heat exchange body, so as to better position the heat exchange body through the positioning ribs 22.

[0076] 1.1 The back plate separates the boss and the electronic control components.

[0077] The electronic control component can be installed in the area of ​​the back plate 11 where the slot 111 is not opened, so that the back plate 11 separates the boss 21 and the electronic control component, avoiding direct contact between the electronic control component and the boss 21, and effectively preventing condensate from flowing from the heat sink 2 to the electronic control component.

[0078] Please continue reading for more details. Figure 2 and Figure 9The inner surface of the back panel 11 may have a recessed area 112, and a slot 111 is provided in the recessed area 112. The electronic control component may be provided in the non-recessed area 112 of the inner surface of the back panel 11, so that the electronic control component can be installed in the area of ​​the back panel 11 where the slot 111 is not provided.

[0079] Furthermore, the height X2 of the boss 21 protruding from the back plate 11 can be less than the depth X1 of the recessed area 112, so that the boss 21 and the electronic control component are spaced apart in the direction of the depth X1 of the recessed area 112. Of course, it is not limited to this. In other embodiments, the height X2 of the boss 21 protruding from the back plate 11 can be greater than or equal to the depth X1 of the recessed area 112.

[0080] The height x 2 of the boss 21 protruding from the back plate 11 can range from 2.2mm to 4.2mm, specifically 2.4mm, 2.7mm, 3.1mm, 3.2mm, 3.6mm, 3.8mm, 4.1mm...

[0081] The depth X1 of the recessed area 112 can range from 1.8mm to 3.8mm, specifically 1.9mm, 2.1mm, 2.4mm, 2.7mm, 2.8mm, 2.9mm, 3.3mm, 3.6mm...

[0082] Furthermore, the electronic control component can be positioned above and / or on the side of the recessed area 112 to prevent condensate on the protrusion 21 on the recessed area 112 from flowing down the inner surface of the back plate 11 to the electronic control component below the recessed area 112. In other embodiments, a cover plate can be provided on the inner surface of the back plate 11, covering the protrusion 21. This prevents liquid on the protrusion 21 from flowing into the interior of the electronic control box body 1. In this case, the electronic control component can be positioned anywhere above, on the side, or below the recessed area 112.

[0083] 1.2. Use template supports to separate the boss and the electrical control components.

[0084] like Figure 10 and Figure 11 As shown, the electrical control box 100 may also include a template bracket 7 disposed between the boss 21 and the electrical control component, so as to separate the boss 21 and the electrical control component by means of the template bracket 7, that is, to make the electrical control component and the boss 21 spaced apart, thereby preventing condensate from flowing from the heat sink 2 to the electrical control component.

[0085] The template support 7 can be made of an insulating and heat-transferring material to insulate the electrical control components and the heat sink 2, and to ensure the heat exchange performance between the heat sink 2 and the electrical control components. For example, it can be made of plastic. However, it is not limited to this. For example, in other embodiments, the template support 7 can also be made of metal.

[0086] The template support 7 can be set inside the back plate 11, that is, inside the electrical control box body 1, so as to support the electrical control components through the template support 7.

[0087] Specifically, the template support 7 can be installed on the boss 21 so that the template support 7 is located inside the back plate 11, and the heat sink 2 can provide support for the template support 7. The boss 21 may have at least one hole (e.g., two holes) to allow fasteners such as screws to pass through and install the template support 7 onto the boss 21. In other embodiments, the template support 7 can be installed on the inner surface of the back plate 11 so that the template support 7 is located inside the back plate 11, and the back plate 11 can provide support for the template support 7, better securing the template support 7 within the electrical control box 100.

[0088] The following content will describe in detail the scheme of installing the template bracket 7 on the boss 21.

[0089] The electrical control module in the electrical control assembly mounted on the template support 7 corresponds one-to-one with the slot 111 and boss 21 of the back plate 11. For example, Figure 10 As shown, the heat sink 2 has three protrusions 21, and the back plate 11 has three slots 111. The electrical control box body 1 is equipped with three module brackets 7 and three electrical control modules: compressor module 61, first fan module 62, and second fan module 63. The slots 111, protrusions 21, and template brackets 7 correspond one-to-one with the electrical control modules. Specifically, the three protrusions 21 on the heat sink 2 are inserted through the three slots 111. The three electrical control modules, compressor module 61, first fan module 62, and second fan module 63, are fixed to the protrusions 21 by different template brackets 7. The projections of compressor module 61, first fan module 62, and second fan module 63 on the template brackets 7 are at least partially overlapped with the projections of the three slots 111. In this way, the efficiency of heat dissipation for compressor module 61, first fan module 62, and second fan module 63 can be improved through the three protrusions 21 of the heat sink 2. Additionally, the compressor module 61 and the first fan module 62 can be mounted on the functional module board 8, allowing them to be mounted on the template bracket 7 via the functional module board 8. The template bracket 7 can be connected to the functional module board 8 via pins. To better secure the functional module board 8 within the electrical control box body 1, it can also be fixedly connected to the back plate 11 using fasteners.

[0090] In other embodiments, the positions of the electrical control modules in the electrical control assembly disposed on the template support 7 and the slots 111 and bosses 21 of the back plate 11 may not correspond one-to-one. For example, two or more electrical control modules can be disposed on the same boss 21 through the template support 7. As another example, one electrical control module can be disposed on two or more bosses 21 through the template support 7.

[0091] Optionally, in the direction perpendicular to the back plate 11 (i.e., in the depth direction (X1 direction) of the recessed area 112 of the back plate 11), the projection of the electronic control module overlaps at least partially with the projection of the slot 111. In this way, the electronic control module can directly exchange heat through the template support 7 and the boss 21, avoiding the need for the electronic control module to exchange heat through the air and the heat sink 2 when the electronic control module and the boss 21 are separated by air, thereby improving the heat exchange efficiency between the electronic control module and the heat sink 2.

[0092] Please continue reading Figure 9 The inner surface of the back plate 11 can be formed with a recessed area 112, and the slot 111 is set in the recessed area 112. The height X2 of the boss 21 protruding from the back plate 11 can be greater than the depth X1 of the recessed area 112. In this way, the template bracket 7 installed on the boss 21 can be spaced apart from the back plate 11. In this way, the condensate on the boss 21 can flow directly along the back plate 11 to the bottom of the electrical control box body 1, avoiding the condensate on the boss 21 from flowing to the electrical control components.

[0093] Specifically, the height x2 of the protrusion 21 from the back plate 11 can range from 2.2mm to 4.2mm, specifically 2.4mm, 2.7mm, 3.1mm, 3.2mm, 3.6mm, 3.8mm, 4.1mm...

[0094] The depth X1 of the recessed area 112 can range from 1.8mm to 3.8mm, specifically 1.9mm, 2.1mm, 2.4mm, 2.7mm, 2.8mm, 2.9mm, 3.3mm, 3.6mm...

[0095] Please continue reading. Figure 2 The recessed area 112 may also be provided with a connecting hole 113 so that fasteners can pass through the connecting hole 113 to fix the heat sink 2 to the back plate 11.

[0096] Specifically, the connection hole 113 can be a countersunk hole, so that the head of the fastener can be at least partially submerged in the connection hole 113, thereby preventing condensate from spreading at the fastener.

[0097] The connecting hole 113 can be a round hole to facilitate drilling during production. Of course, in other embodiments, the connecting hole 113 can also be square, rhomboid, etc.

[0098] In addition, please continue to refer to Figure 4 The boss 21 can be configured as a flow guiding structure 211 to guide the condensate on the boss 21 to the bottom of the electrical control box 100, so as to prevent the condensate on the boss 21 from flowing to the electrical control components.

[0099] In this embodiment, the surface of the boss 21 facing the electronic control component is a flow guiding structure 211. Specifically, the flow guiding structure 211 can be an inclined surface sloping towards the bottom of the electronic control box 100, so that condensate on the boss 21 can flow directly along the inclined surface towards the bottom of the electronic control box 100 to the bottom of the electronic control box 100. For example, the upper part of the surface of the boss 21 facing the electronic control component is a triangular structure. In other embodiments, the boss 21 is a conical structure, and the size of the conical boss 21 gradually decreases from the inner side of the back plate 11 to the outer side of the back plate 11, so that condensate on the boss 21 can first flow along the side wall of the boss 21 to the radiator body, and then flow along the gap between the radiator body and the back plate 11 to the bottom of the electronic control box 100.

[0100] To facilitate the flow of condensate from the boss 21 to the bottom of the electrical control box 100, please refer to [further details]. Figure 5 A gap 114 may be provided between the slot 111 and the boss 21 so that the condensate on the boss 21 can flow downward or outward along the gap 114 between the slot 111 and the boss 21 and then flow to the bottom of the electrical control box 100.

[0101] The gap 114 between the groove edge of the slot 111 near the bottom of the electrical control box 100 and the boss 21 can be 1mm to 3mm. This allows condensate on the boss 21 to flow downwards or outwards along the gap 114 between the slot 111 and the boss 21, ultimately reaching the bottom of the electrical control box 100. Specifically, the gap 114 between the groove edge of the slot 111 near the bottom of the electrical control box 100 and the boss 21 can be 1.2mm, 1.6mm, 1.9mm, 2.0mm, 2.2mm, 2.5mm, 2.6mm, 2.8mm, etc.

[0102] 2. Protective fixing of radiators

[0103] In this embodiment, please continue to refer to Figure 3 The control box 100 may also include a heat sink 3 disposed on the outside of the back plate 11 to dissipate heat for the control box body 1 and its internal electronic control components. The control box may also include a protective plate 4, wherein the heat sink 3 is disposed between the control box body 1 and the protective plate 4 to protect and fix the microchannel heat sink 3.

[0104] like Figure 7 As shown, the radiator 3 may include a heat exchange body, which has multiple channels. These channels are divided into a first channel and a second channel, and the first channel can contact the second channel to exchange heat between the first refrigerant flow in the first channel and the second refrigerant flow in the second channel. This ensures that the radiator 3 has sufficient cooling capacity to dissipate heat from the electrical control box body 1 and its internal electrical control components. Both the first channel and the second channel can be microchannels.

[0105] Preferably, the extending direction of the first channel may be the same as that of the second channel to increase the contact area between the first channel and the second channel, thereby improving the heat exchange efficiency between the first channel and the second channel.

[0106] In this embodiment, the heat exchange body may include at least one first plate body 31 and at least one second plate body 31. At least one first channel is provided in the first plate body 31, and at least one second channel is provided in the second plate body 31. For example, the heat exchange body may include three first plate bodies 31 and two second plate bodies 31. In other embodiments, the heat exchange body may include at least one plate body 31, and the multiple channels in each plate body 31 may be divided into alternately arranged first channels and second channels. Herein, the first plate body 31 and the second plate body 31 may both be collectively referred to as the plate body 31.

[0107] Starting from the function of the plate body 31, the plate body 31 may also be referred to as a heat exchange tube. When both the first channel and the second channel are microchannels, the plate body 31 may also be referred to as a microchannel heat exchange tube.

[0108] The plate bodies 31 may all be flat tubes so that the heat dissipation plate 2 can be arranged on the plate bodies 31. In other embodiments, the plate bodies 31 may also be carriers with other cross-sectional shapes, such as cylinders, cuboids, cubes, etc.

[0109] Herein, the cross-sectional shape of the plate body 31 along the flowing direction of the refrigerant in the plate body 31 may be an I shape. In other embodiments, the cross-sectional shape of the plate body 31 along the flowing direction of the refrigerant in the plate body 31 may be one of an L shape, a U shape, a G shape, a "匚" shape or a circular shape.

[0110] The radiator 3 may further include at least one manifold, and the manifold is connected to the channels in at least part of the plate bodies 31 to supply the refrigerant flow to the channels in at least part of the plate bodies 31 or collect the refrigerant flow flowing through the channels in at least part of the plate bodies 31 by using the manifold. Herein, each manifold may include a pipe body and end caps respectively provided at opposite ends of the pipe body.

[0111] Corresponding to the heat exchange body including at least one first channel and at least one second channel, at least one manifold may include at least one first manifold 32 and at least one second manifold 33. Herein, the first manifold 32 is connected to the first channel to supply the first refrigerant flow to at least one first channel and / or collect the first refrigerant flow flowing through at least one first channel through the first manifold 32, and the second manifold 33 is connected to the second channel to supply the second refrigerant flow to at least one second channel and / or collect the second refrigerant flow flowing through at least one second channel through the second manifold 33, so that the first refrigerant flow flowing through the first channel and the second refrigerant flow flowing through the second channel perform heat exchange, so as to achieve subcooling of the refrigerant flow in one of the first channel and the second channel.

[0112] Furthermore, each of the first manifold 32 and the second manifold 33 may include two units. One first manifold 32 is used to supply a first refrigerant flow to the first channel, and the other first manifold 32 is used to collect the first refrigerant flow flowing through the first channel. One second manifold 33 is used to supply a second refrigerant flow to the second channel, and the other second manifold 33 is used to collect the second refrigerant flow flowing through the second channel. The two first manifolds 32 may be located on opposite sides of the plate 31 in the radiator 3, and the two second manifolds 33 may also be located on opposite sides of the plate 31 in the radiator 3. Additionally, one first manifold 32 and one second manifold 33 may both be located on the same side of the plate 31 in the radiator 3, and the other first manifold 32 and the other second manifold 33 may also both be located on the same side of the plate 31 in the radiator 3.

[0113] To facilitate communication between the manifold and the first or second channel, a flow hole may be provided on the manifold, allowing the plate 31 to pass through the flow hole and enter the manifold, thereby enabling the first or second channel inside the plate 31 to communicate with the manifold.

[0114] The long side of the flow hole can be perpendicular to the axial direction of the manifold to which it belongs, so that the flow hole on the manifold assembly is a transverse punch. This can make full use of the manifold wall material to achieve the punching and flanging depth, thereby increasing the contact area when the manifold and flat tube are welded and improving the pressure resistance of the weld.

[0115] The radiator 3 may also include an auxiliary connecting pipe 34 connected to the manifold, so as to introduce refrigerant flow into the manifold or draw out refrigerant flow in the manifold through the auxiliary connecting pipe 34.

[0116] The length direction of the auxiliary connecting pipe 34 can be the same as the length direction of the plate 31 to facilitate the arrangement of the heat sink.

[0117] The number of manifolds can be the same as the number of auxiliary connecting pipes 34, and the manifolds and auxiliary connecting pipes 34 are connected in a one-to-one correspondence.

[0118] When the heat sink 3 includes two first manifolds 32 and two second manifolds 33, the heat sink 3 may include four auxiliary connecting pipes 34, which are used to connect the two first manifolds 32 and the two second manifolds 33 respectively.

[0119] One of the first current collectors 32 and one of the second current collectors 33 can be located at the upper end of the protective plate 4 of the electrical control box 100, and the other first current collector 32 and the other second current collector 33 can be located at the lower end of the protective plate 4.

[0120] The auxiliary connecting pipe 34, which connects to the manifold at the lower end of the protective plate 4, is extended by a bend to avoid mutual friction with the auxiliary connecting pipe 34 connected to the manifold at the upper end of the protective plate 4, and also facilitates welding operations. Alternatively, the auxiliary connecting pipe 34 connected to the manifold at the lower end of the protective plate 4 can first extend upwards from the manifold to the middle of the protective plate 4, then bend and extend downwards. Furthermore, the auxiliary connecting pipe 34 connected to the manifold at the lower end of the protective plate 4 can be spaced apart from the auxiliary connecting pipe 34 connected to the manifold at the upper end of the protective plate 4 to avoid mutual friction with the upper main and auxiliary pipelines, and also facilitate welding operations.

[0121] like Figure 12 As shown, the protective plate 4 includes an upper connecting part 41 connected to the upper end of the electrical control box body 1, a lower connecting part 42 connected to the lower end of the electrical control box body 1, and a protective part 43 between the upper connecting part 41 and the lower connecting part 42; the heat sink 3 is located between the protective part 43 and the back plate 11, so that the heat sink 3 is placed between the protective plate 4 and the back plate 11 of the electrical control box body 1 to avoid the heat sink 3 being subjected to direct external impact, thus protecting the heat sink 3 and solving the technical problems of the heat sink 3 being unable to be directly installed and easily deformed when dissipating heat for the electrical control components; and the structure is compact, stable and reliable, which can meet the requirements of miniaturization design of the electrical control box 100, with good heat dissipation effect and low application cost.

[0122] Among them, the protective plate 4 can be used as an electrical control assembly tool.

[0123] like Figure 13 As shown, the upper connecting part 41 can be connected to the upper folding plate 14, wherein the upper folding plate 14 is disposed on the upper end of the electrical control box body 1 and connected to the back plate 11. In this embodiment, the upper connecting part 41 can overlap the upper folding plate 14. Additionally, as... Figure 13 and Figure 14 As shown, a limiting groove 141 may be formed on the side of the upper folding plate 14 away from the back plate 11, so that when the upper connecting part 41 overlaps the upper folding plate 14, the protective part 43 is engaged in the limiting groove 141, so as to facilitate the installation and positioning of the protective part 43. In other embodiments, a limiting groove 141 may be formed on the edge of the upper folding plate 14 facing the back plate 11, so that when the upper connecting part 41 overlaps the upper folding plate 14, the protective part 43 is engaged in the limiting groove 141.

[0124] Furthermore, the upper connecting part 41 can also be connected to the top plate 121 of the electrical control box body 1 by fasteners, so as to stably install the upper connecting part 41 on the electrical control box body 1. Specifically, the upper connecting part 41 can be disposed between the top plate 121 and the upper folding plate 14 to define the position of the upper connecting part 41, so as to facilitate the installation and positioning of the protective plate 4.

[0125] Please continue reading. Figure 12The lower connecting portion 42 can be an L-shaped plate including a first plate and a second plate. The end of the first plate away from the second plate is connected to the protective portion 43, and the end of the second plate away from the first plate is disposed between the radiator 3 and the back plate 11, and covers the radiator 3. The lower connecting portion 42 can be fixedly connected to the lower end of the electrical control box body 1 via the second plate, so that the upper connecting portion 41 can be stably installed on the electrical control box body 1. The second plate can be fixedly installed on the electrical control box body 1 by one, two, or more screws or other fasteners, and at least one manifold located at the lower end of the protective portion 43 can be positioned by these fasteners. Additionally, the second plate may also have a limiting plate 421 extending towards the panel of the electrical control box body 1, and the electrical control box body 1 (e.g., the back plate 11) may also have a limiting opening 115, so that when the protective plate 4 is installed on the electrical control box body 1, the limiting plate 421 is engaged in the limiting opening 115, so that the lower connecting portion 42 is better installed and positioned through the limiting opening 115. The above content can also be described as follows: The lower connecting part 42 is a connecting frame, which covers the heat sink 3 and is fixedly connected to the lower end of the electrical control box body 1; the connecting frame is fixedly installed on the electrical control box body 1 by one, two or more screws or other fasteners; a limiting plate 421 is set on the connecting frame, and a limiting port 115 is set at the upper end of the electrical control box body 1, and the limiting plate 421 is snapped into the limiting port 115.

[0126] The protective part 43 of this application may be provided with a relief groove 433 corresponding to the manifold in the heat sink 3 on the side facing the back plate 11, so that the manifold can be inserted into the relief groove 433, thereby facilitating the installation and positioning of the manifold and the installation and positioning of the plate 31 connected to the manifold.

[0127] Furthermore, the protective section 43 may include a main protective plate 431 covering the manifold and plate 31 in the radiator 3. A relief groove 433 may be provided on the main protective plate 431 so that the relief groove 433 on the protective section 43 corresponds to the position of the manifold.

[0128] When at least two manifolds are provided at one end (e.g., the upper or lower end) of the protective section 43, a portion of the manifolds at the same end of the protective section 43 can be installed and positioned using the clearance groove 433 on the main protective plate 431, and the remaining portion of the manifolds at the same end of the protective section 43 can be installed and positioned using a fastener (e.g., the lower connecting part 42 connected to the lower end of the protective section 43). The fastener at the upper end of the protective section 43 can also be connected to the electrical control box body 1 using fasteners to better install and position the remaining portion of the manifolds at the upper end of the protective section 43.

[0129] The protective section 43 may also include one, two or more auxiliary protective plates 432. The auxiliary protective plates 432 are connected to the main protective plate 431 and are located on the side of the main protective plate 431 away from the radiator 3.

[0130] Furthermore, one of the auxiliary protective plates 432 can cooperate with the back plate 11 to form a protective space for accommodating the auxiliary connecting pipe 34 (it can also be understood that the auxiliary protective plate 432 forms a protective space). In this way, the protective space formed by the protective part 43 allows the auxiliary connecting pipe 34 and the upper condenser inlet pipe (not shown) to be avoided when assembling the manifold and plate 31 in the radiator 3, thereby simplifying the structure, saving space, and protecting the auxiliary connecting pipe 34.

[0131] The auxiliary protective plate 432 forming the protective space can be L-shaped so that the auxiliary protective plate 432 forms a protective space, and the side wall of the L-shaped auxiliary protective plate 432 away from the back plate 11 can protect the auxiliary connecting pipe 34.

[0132] like Figure 15 As shown, the protective plate 4 may also include a connecting pipe fixing plate 44, which is used to fix the auxiliary connecting pipe 34 relative to the electrical control box body 1, and can also adjust the relative position between at least two auxiliary connecting pipes 34, thereby avoiding mutual rubbing between the auxiliary connecting pipes 34.

[0133] Among them, such as Figure 16 As shown, the connecting pipe fixing plate 44 may have a groove (which may be called a positioning groove 441) so that the auxiliary connecting pipe 34 can be placed in the positioning groove 441, thereby facilitating the positioning and installation of the auxiliary connecting pipe 34.

[0134] The number of positioning slots 441 in the connecting pipe fixing plate 44 is not limited and can be set according to the number of auxiliary connecting pipes 34 in the radiator 3. Specifically, the number of positioning slots 441 in the connecting pipe fixing plate 44 is equal to the number of auxiliary connecting pipes 34 in the radiator 3. For example, if there are at least two auxiliary connecting pipes 34, then at least two positioning slots 441 can be formed on the connecting pipe fixing plate 44, and at least two auxiliary connecting pipes 34 are correspondingly locked into the positioning slots 441. In other embodiments, the number of positioning slots 441 in the connecting pipe fixing plate 44 can be equal to the number of auxiliary connecting pipes 34 connected to the manifold at the upper end of the protective part 43. For example, if there are two manifolds at the upper end of the protective part 43, and two auxiliary connecting pipes 34 are connected to the manifolds at the upper end of the protective part 43, then the connecting pipe fixing plate 44 can also have two positioning slots 441, and the two auxiliary connecting pipes 34 connected to the manifolds at the upper end of the protective part 43 are correspondingly locked into the two positioning slots 441.

[0135] The connecting pipe fixing plate 44 can be fixedly connected to the back plate 11 or the heat sink 2 so as to fix the connecting pipe fixing plate 44 in place. Thus, the connecting pipe fixing plate 44 can be fixed to the electrical control box body 1 through the back plate 11 or the heat sink 2, so that the auxiliary connecting pipe 34, which is clipped on the connecting pipe fixing plate 44, is relatively fixed to the electrical control box body 1.

[0136] 3. The electrical control box has a double-layer structure.

[0137] Please continue reading. Figure 1 and Figure 18 The electrical control box 100 may also include an electrical control mounting plate 5. The electrical control mounting plate 5 is connected to the side plate 12 and is disposed in the mounting space 13 at a distance from the back plate 11. In this way, the electrical control box 100 is divided into two layers by the electrical control mounting plate 5, with the electrical control box body 1 as the inner layer and the electrical control mounting plate 5 as the outer layer. This makes the electrical control module arrangement in the electrical control box 100 more compact and reduces the volume occupied by the electrical control box 100 in terms of space.

[0138] Optionally, such as Figure 19 As shown, a filter board 64 is provided on the side of the electrical control mounting plate 5 near the back plate 11 to filter the power supply current and supply the filtered current to at least some of the other electrical control modules in the electrical control box 100, so as to avoid the influence of power supply voltage or current fluctuations on at least some of the other electrical control modules. Furthermore, the placement of the filter board 64 on the side of the electrical control mounting plate 5 near the back plate 11 facilitates the electrical connection of the filter board 64 and the electrical control modules located on the inside of the back plate 11 and on the side of the electrical control mounting plate 5 away from the back plate 11 with a simpler circuit. The wiring inside the electrical control box 100 is simple and uncomplicated, reducing the risk of wiring tangling inside the electrical control box 100, and allowing electrical control modules to be placed in more places (such as the side of the electrical control mounting plate 5 away from the back plate 11, the side of the electrical control mounting plate 5 near the back plate 11, and the inside of the back plate 11), thereby improving the space utilization rate inside the electrical control box 100.

[0139] In addition, such as Figure 18 and Figure 19 As shown, the electrical control mounting plate 5 may be provided with a recessed mounting platform that is inclined toward the back plate 11. A terminal block 65 may be provided on the side of the recessed mounting platform away from the back plate 11. By placing the terminal block 65 in the outer mounting space, in the event of a poor contact problem with the terminal block 65, the electrical control mounting plate 5 can be repaired without disassembling or flipping it. Moreover, the recessed mounting platform can separate the terminal block 65 from the electrical control module set on the back plate 11, avoiding interference caused by the terminal block 65 and the electrical control module set on the back plate 11 being too close.

[0140] like Figure 19 and Figure 20As shown, a gap may be formed between the recessed mounting platform and the electrical control mounting plate 5, which facilitates the routing of the connection wires of the electrical control module in the inner mounting space to the terminal block 65. For example, the filter board 64 can be electrically connected to the terminal block 65 through the gap, and the connecting wires 95 of the filter board 64 can be routed to the terminal block 65 through the gap.

[0141] Optionally, the gap between the recessed mounting platform and the electrical control mounting plate 5 may include a first gap 53 between the top of the recessed mounting platform and the electrical control mounting plate 5. When the filter plate 64 is located on the top of the recessed mounting platform away from the bottom of the recessed mounting platform, the filter plate 64 can be electrically connected to the terminal block 65 through the first gap 53, which can reduce the length of the connecting wire 95 between the filter plate 64 and the terminal block 65.

[0142] In addition, the gap between the recessed mounting platform and the electrical control mounting plate 5 may also include a second gap 54 between the bottom end of the recessed mounting platform and the electrical control mounting plate 5. This allows wires to be led from the terminal block 65 to the outside of the electrical control box 100 for connection with an external power source. Thus, the power from the external power source can be supplied to the filter board 64 through the terminal block 65, which reduces the wiring length, makes the wiring more compact, and facilitates wiring.

[0143] Optionally, the top end of the recessed mounting platform is closer to the back plate 11 than the bottom end; that is, the distance between the top end of the recessed mounting platform and the back plate 11 is greater than the distance between the bottom end of the recessed mounting platform and the back plate 11. In other embodiments, the bottom end of the recessed mounting platform may also be closer to the back plate 11 than the top end; no specific limitation is imposed here.

[0144] Optionally, the edges of the recessed mounting platform can be flattened to prevent the edges of the recessed mounting platform from scratching the wires.

[0145] Please continue reading for more details. Figure 19 A billing board 66 may also be installed on the side of the electrical control mounting plate 5 near the back panel 11. The billing board 66 can be connected to the filter board 64 to calculate the power consumption of the outdoor unit of the air conditioner where the electrical control box 100 is located. The billing board 66 can also be installed on the top of the recessed mounting platform away from the bottom of the recessed mounting platform, just like the filter board 64. This can reduce the length of the connecting wire between the billing board 66 and the filter board 64, making the wiring more compact and reducing the risk of wire tangling inside the electrical control box 100. Moreover, it makes reasonable use of the space resources on the side of the electrical control mounting plate 5 near the back panel 11, improving the space utilization rate of the electrical control box 100 and improving the layout rationality of the electrical control modules inside the electrical control box 100.

[0146] Please continue reading. Figure 20A control motherboard 67 can be installed on the side of the electrical control mounting plate 5 away from the back panel 11. The control motherboard 67 and the filter board 64 are electrically connected so that the filter board 64 supplies power to the control motherboard 67, thereby reducing the impact of power supply voltage or current fluctuations on the control motherboard 67. In addition, by setting the control motherboard 67 and the filter board 64 on opposite sides of the electrical control mounting plate 5, the wiring chaos or mutual interference caused by the close proximity between the control motherboard 67 and the functional module board 8 can be avoided.

[0147] The control motherboard 67 can also be located on the top of the recessed mounting platform, away from the bottom of the recessed mounting platform. This allows for the arrangement of more electrical control modules on the electrical control mounting plate 5, making the electrical control mounting plate 5 relatively smaller, which is beneficial for the miniaturization of the electrical control box 100.

[0148] The control mainboard 67 is connected to a detection line 91 and a communication line 92. The detection line 91 and communication line 92 can be laid on the side wall of the electrical control mounting plate 5 away from the back panel 11, and can be led out of the electrical control box 100 from its bottom end. The detection line 91 connects to the detection equipment of the outdoor unit of the air conditioner to transmit the detection data from the equipment to the control mainboard 67. The detection equipment may include temperature sensors, pressure sensors, pressure switches, electronic expansion valves, etc., installed on the heat exchange pipes of the outdoor unit. The communication line 92 can connect to the indoor unit of the air conditioner, an electricity meter, a central controller, etc., to achieve communication. Both the detection line 91 and the communication line 92 carry low-voltage electricity (such as 12V or 24V) for signal transmission.

[0149] A heating module (not shown) can be installed on the control main board 67. The heating module can be a circuit structure for supplying power to the heater on the outdoor unit of the air conditioner. A first power supply line 93 can be laid on the side wall of the electrical control mounting plate 5 away from the back plate 11. One end of the first power supply line 93 is connected to the control main board 67, and the other end of the first power supply line 93 can be led out from the bottom of the electrical control mounting plate 5 to the outside of the electrical control box 100 to connect to an external power source, and then supply power to the heating module through the first power supply line 93. In addition, the heating module can be connected to the heater through a heating wire 94.

[0150] In the above implementation, the detection line 91 and the communication line 92 can be located at the first side end 55 of the electrical control mounting plate 5, and the first power supply line 93 and the heating line 94 are located at the second side end 56 of the electrical control mounting plate 5 opposite to the first side end 55. With this arrangement, the wires transmitting high voltage and the wires transmitting low voltage can be arranged separately, that is, the distance between the wires transmitting high voltage and the wires transmitting low voltage can be increased to avoid mutual interference and improve the performance of the electrical control box 100.

[0151] In addition, an expansion function board 68 can be provided on the side of the electrical control mounting plate 5 away from the back plate 11. The expansion function board 68 can be a circuit board with other functions. This arrangement facilitates the upgrading of the electrical control box 100.

[0152] The expansion function board 68 can also be set on the top of the recessed mounting platform away from the bottom of the recessed mounting platform. This can reduce the length of the connection line between the control motherboard 67 and the expansion function board 68, making the wiring more compact and reducing the risk of wire tangling inside the control box 100. Moreover, it makes reasonable use of the space resources on the side of the control mounting plate 5 away from the back plate 11, improving the space utilization of the control box 100 and improving the layout rationality of the control modules inside the control box 100.

[0153] Alternatively, please continue reading Figure 18 The electrical control mounting plate 5 can be hinged to the side plate 12. After installation, the electrical control mounting plate 5 is rotated into the installation space 13 and spaced apart from the back plate 11. This hinged arrangement allows the electrical control mounting plate 5 to be rotated outwards relative to the electrical control box body 1 (e.g., 90° outwards). This eliminates the need to disassemble the electrical control mounting plate 5 when repairing the electrical control module inside the electrical control box body 1, thereby improving the repair efficiency of the electrical control box 100 and reducing damage caused by human intervention such as stepping or collision deformation after the sheet metal of the electrical control box 100 is cut off during repair. Figure 17 As shown, the electrical control mounting plate 5 can be hinged to the side plate 12 via hinges or other hinge components 57. The number of hinges or other hinge components 57 can be greater than or equal to two, so that the electrical control mounting plate 5 can be stably hinged to the side via at least two hinges. In other embodiments, the electrical control mounting plate 5 can also be connected to the side plate 12 via other connection methods (such as riveting or snap-fitting).

[0154] The edge of the electronic control mounting plate 5 may be formed with a folded edge 51 extending away from the back plate 11, so that the electronic control mounting plate 5 becomes an inwardly recessed structure through the folded edge 51, so as to avoid interference between the electronic control module provided on the side of the electronic control mounting plate 5 away from the back plate 11 and the panel, and to protect the electronic control module provided on the side of the electronic control mounting plate 5 away from the back plate 11.

[0155] The folded edge 51 can be hinged to the side plate 12, allowing the electrical control mounting plate 5 to rotate into the mounting space 13. The end of the folded edge 51 away from the back plate 11 can be hinged to the side plate 12 to increase the degree of freedom of the electrical control mounting package to flip.

[0156] Furthermore, the electrical control mounting plate 5 can be formed with folded edges 51 extending in the direction away from the back plate 11 on all four sides, so as to better protect the electrical control module set on the side of the electrical control mounting plate 5 away from the back plate 11.

[0157] It is understood that the first side end 55 of the aforementioned electronic control mounting plate 5 can refer to the hinge end of the electronic control mounting plate 5, and the second side end 56 of the electronic control mounting plate 5 can refer to the end of the electronic control mounting plate 5 opposite to the hinge end. Of course, in other embodiments, the first side end 55 of the electronic control mounting plate 5 can also refer to the end of the electronic control mounting plate 5 opposite to the hinge end, and the second side end 56 of the electronic control mounting plate 5 can refer to the hinge end of the electronic control mounting plate 5.

[0158] In addition, the aforementioned control motherboard 67 can be positioned close to the hinge end of the electrical control mounting plate 5. This way, when the electrical control mounting plate 5 is flipped, the relative movement of the control motherboard 67, which has many connecting wires, is smaller. Consequently, the tension on the connecting wires between the control motherboard 67 and other electrical control modules is smaller, making it less likely for the connecting wires between the control motherboard 67 and other electrical control modules to have problems. This reduces the impact of flipping the electrical control mounting plate 5 on the electrical connection between the control motherboard 67 and other electrical control modules.

[0159] Similarly, as Figure 19 As shown, the filter board 64 can also be set close to the hinge end of the electronic control mounting plate 5. In this way, when the electronic control mounting plate 5 is flipped, the relative movement of the filter board 64, which has many connecting wires, is small. As a result, the tension on the connecting wires between the filter board 64 and other electronic control modules (such as the functional module board 8) is small, making it less likely for the connecting wires between the filter board 64 and other electronic control modules to have problems. This reduces the impact of flipping the electronic control mounting plate 5 on the electrical connection between the filter board 64 and other electronic control modules.

[0160] Optionally, such as Figure 21 As shown, a functional module board 8 may be provided on the inner side of the back panel 11. The functional module board 8 can be electrically connected to the filter board 64 so that the filter board 64 can supply power to the functional module board 8, which can reduce the impact of power supply voltage or current fluctuations on the functional module board 8. The functional module board 8 may be provided with a first fan module 62 and / or a compressor module 61.

[0161] In addition, a reactor 69 electrically connected to the functional module board 8 may be provided on the inner side of the back plate 11.

[0162] A second fan module 63 may also be installed on the inner side of the back panel 11.

[0163] In addition, the aforementioned electrical control box 100 may also be equipped with a wind-cooling heat dissipation device, so that the electrical control box 100 of this application has both wind-cooling and refrigerant heat dissipation functions, and the heat exchange efficiency is higher.

[0164] The structures in the above embodiments can be combined with each other. Additionally, the radiator 2 in the above embodiments can be used as an economizer.
