Description

Technical Field

[0001] This application relates to the technical field of air conditioning, and more specifically, to an air conditioning control box and air conditioning equipment. Background Technology

[0002] Because copper busbars can withstand high currents, they are commonly used in the electrical control boxes of outdoor units of industrial air conditioners to connect electrical components. In developing this invention, the inventors discovered at least the following problems with the existing technology: In the outdoor unit of an industrial air conditioner, the electrical control box is installed below the condenser. Within the control box, the length of the copper busbar is horizontal, and its width is vertical. When multiple copper busbars are installed within the control box, a certain spacing must be maintained between them, which increases the overall height of the control box, thus increasing the overall height of the outdoor unit, or compresses the space below the control box, which is used for wiring, thereby affecting user operation.

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] This application provides an air conditioner control box and air conditioning equipment, which can reduce the space occupied by copper busbars and expand the space area for wiring inside the air conditioner control box.

[0031] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present 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 the present application, and not all of them. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0032] The terms "first," "second," "third," "fourth," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in a sequence other than that illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0033] Currently, in electrical control boxes, the length of the copper busbars is horizontal and the width is vertical. When multiple copper busbars are installed in the electrical control box, a certain distance needs to be maintained between them, which increases the height of the entire electrical control box, thereby increasing the height of the entire outdoor unit, or compressing the space under the electrical control box. The space under the electrical control box is used for wiring, which in turn affects user operation.

[0034] To resolve the above technical issues, please refer to [link / reference]. Figure 1 This is one embodiment of the air conditioner control box 10 in this application. The air conditioner control box 10 includes a housing 100, electrical components 200, and a copper busbar module. Both the electrical components 200 and the copper busbar module are disposed inside the housing 100. The copper busbar module is used to transmit large current in the circuit and connect various electrical components 200, such as connecting power input terminals, compressor terminals, relays, contactors, etc., and plays the role of collecting and distributing current.

[0035] The housing 100 includes a top plate, a mounting plate, a cover plate, and two side plates. The mounting plate is arranged vertically, with the top plate located on top of the mounting plate and the bottom plate located on the bottom of the mounting plate. The side plates are located on opposite sides of the mounting plate. The mounting plate, top plate, bottom plate, and two side plates are sequentially assembled to form a box-like structure. The cover plate is parallel to the mounting plate and covers the box-like structure. In this embodiment, the first direction is the length direction of the housing 100, the second direction is the thickness direction of the housing 100, and the vertical direction is the width direction of the housing 100. The first direction, the second direction, and the vertical direction are perpendicular to each other.

[0036] Please see Figure 1 and Figure 2The copper busbar module includes a first copper busbar 310 and a second copper busbar 320, which are spaced apart within the housing 100. Both the first and second copper busbars are electrically connected to the electrical component 200. In this embodiment, the length of the first copper busbar is along a first direction, and its width is along a second direction, which are parallel to the horizontal direction. Based on the existing electrical component 200 and within the limited space of the air conditioning control box 10, the arrangement of the first copper busbar 310 reduces its space occupancy in the vertical direction along the housing 100, i.e., reduces its space occupancy in the height direction, thereby expanding the wiring area within the air conditioning control box 10. Furthermore, it reduces the height of the air conditioning control box 10, thus reducing its overall volume.

[0037] The second copper busbar 320 is positioned along the length of the first direction and along the width of the vertical direction. This arrangement effectively utilizes the space along the second direction in the air conditioning control box 10. The second copper busbar 320, in conjunction with the first copper busbar 310, further improves the space utilization of the copper busbar module within the housing 100, thereby providing more installation space for electrical components 200 or further reducing the overall size of the air conditioning control box 10.

[0038] Furthermore, multiple first copper busbars 310 can be arranged side-by-side along the second direction, and multiple second copper busbars 320 can be arranged side-by-side along the vertical direction. The area and number of first copper busbars 310 and second copper busbars 320 can be maximized, which can effectively increase the conductive cross-sectional area, thereby reducing the impedance per unit length. This not only improves the current carrying capacity but also reduces energy loss caused by excessive resistance. Secondly, the side-by-side arrangement of first copper busbars 310 along the second direction can effectively utilize the space in the thickness direction of the housing 100, and the side-by-side arrangement of second copper busbars 320 along the vertical direction can effectively utilize the space in the width direction of the housing 100. Since the first copper busbars 310 and second copper busbars 320 generate heat during operation, especially under high load conditions, if the cross-section of a single copper busbar is too large, it may lead to excessively high local temperatures, which may affect the working stability of surrounding components. Therefore, dividing the first copper busbars 310 and second copper busbars 320 into multiple smaller units and arranging them in a stacked manner can significantly improve the heat dissipation effect. Sufficient gaps are left between each first copper busbar 310 and second copper busbar 320 to promote air circulation, further reducing the possibility of heat accumulation.

[0039] Please see Figure 1 and Figure 2The electrical component 200 includes a power converter 210, and the air conditioning control box 10 also includes multiple connectors 400. The power converter 210 is electrically connected to the first copper busbar 310 and the second copper busbar 320 via the connectors 400. The power converter 210 is used to monitor the power circuit and automatically switch the load circuit from one power source to another when a fault occurs in the normal power supply line, so as to ensure continuous power supply to the equipment. The power converter 210 is located on one side of the air conditioning control box 10 and close to the power input. The power converter 210 is fixed to the mounting plate by corresponding mounting brackets or fixing holes to ensure a firm installation and prevent loosening due to vibration or other reasons.

[0040] Specifically, the first copper busbar 310 and the second copper busbar 320 are located at both ends of the power converter 210, with the first copper busbar 310 positioned on the upper part of the mounting plate and the second copper busbar 320 positioned on the lower part of the mounting plate. The spatial arrangement of the first copper busbar 310 and the second copper busbar 320 improves the vertical space utilization of the housing, providing ample space for the installation of the power converter 210 in the vertical direction.

[0041] The power converter 210 is provided with a first connecting contact 211 and a second connecting contact 212. The first connecting contact 211 is electrically connected to the first copper busbar 310 through a portion of the connector 400, and the second connecting contact 212 is electrically connected to the second copper busbar 320 through another portion of the connector 400. In this embodiment, the length direction of the connector 400 is arranged vertically, and multiple connectors 400 are arranged side by side and spaced apart along a first direction. The first connecting contact 211 and the second connecting contact 212 are respectively located on the upper and lower ends of the power converter 210, facilitating the power converter 210 to be electrically connected to the first copper busbar 310 and the second copper busbar 320 through the connectors 400. Understandably, the arrangement of connectors 400 ensures sufficient spacing between adjacent components, clearly defining the boundaries between functional units and facilitating precise assembly. Secondly, during subsequent debugging and maintenance, the clearly visible wiring paths between the first contact point 211 and the first copper busbar 310, and between the second contact point 212 and the second copper busbar 320, reduce the risk of misoperation. Technicians can quickly locate the problem area without disassembling complex stacked layers, facilitating routine inspections and troubleshooting, and accelerating the repair process.

[0042] Furthermore, the power converter 210 has a first end face 212 and a second end face 213 arranged opposite to each other. The first end face 212 is provided with a display screen and faces the cover plate, while the second end face 213 faces the mounting plate. It is understood that the first end face 212 with the display screen facing the cover plate means that the power converter 210 is placed facing forward. This forward-facing placement of the power converter 210 implies deployment according to the manufacturer's recommended best practices, maximizing the use of the pre-defined interface positions, reducing additional modification costs, and mitigating potential risks. Secondly, during troubleshooting, a clearly visible operating interface is often relied upon for initial judgment. When the display screen or other status indicators on the first end face 212 face the operator, it provides intuitive information feedback. This forward-facing placement allows operators to obtain key data immediately without having to go around to the back of the device, thereby improving work efficiency.

[0043] Because the copper busbar 300 will vibrate during transportation, and the copper busbar 300 along the first direction is relatively long, the bolts, due to frictional changes caused by mechanical vibration and material fatigue effects, may loosen, leading to poor contact between the first copper busbar 310 and / or the second copper busbar 320 and the supporting components, increasing resistance and causing problems such as localized overheating or arcing. To solve the above problems, the air conditioning control box 10 also includes a buffer pad 500 (not shown in the figure). The buffer pad 500 is disposed between two adjacent first copper busbars 310 and / or second copper busbars 320, and the buffer pad 500 is detachably connected to the mounting plate. It is understood that adding the buffer pad 500 is an effective vibration reduction measure. The buffer pad 500 can reduce the vibration amplitude directly transmitted to the copper busbar 300 by absorbing impact energy. Secondly, the buffer pad 500 can also prevent scratches on the metal surface and extend the service life of the components.

[0044] To further protect the first copper busbar 310 and the second copper busbar 320 during transportation, in other embodiments, thick and rigid buffer pads 500 can be installed at both ends of the first copper busbar 310 and the second copper busbar 320 near the bolts. Since the two ends of the copper busbar 300 are usually areas of concentrated stress, especially during transportation when the back-and-forth swaying caused by inertia is most significant, the pressure transmission in this part can be effectively reduced.

[0045] The cushioning pad 500 is detachably connected to the mounting plate, allowing it to be installed during transportation. When actually using the air conditioning control box 10, the cushioning pad 500 can be removed, enhancing flexibility and improving maintenance convenience. During transportation, the detachable design allows the cushioning pad 500 to be individually packaged before shipment, avoiding direct contact with other components. This separation reduces the risk of damage from collisions or compression. Furthermore, the separated cushioning pad 500 can be flexibly configured to suit the size and shape of different products.

[0046] Please see Figure 3 This application also discloses an air conditioning device, which includes the above-mentioned air conditioning control box 10 and condenser 20. The air conditioning control box 10 is located below the condenser 10. Since the air conditioning device adopts all the technical solutions of all the embodiments of the above-mentioned air conditioning control box 10, it has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, which will not be described in detail here.

[0047] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
