[0011] In one possible implementation, the fin assembly includes a substrate and a plurality of heat dissipation fins, the heat dissipation fins being sheet-like and perpendicularly connected to the substrate, and the plurality of heat dissipation fins being arranged in parallel and at equal intervals along the second direction.

[0012] A heat dissipation channel is formed between two adjacent heat dissipation fins, and the two ends of the heat dissipation fins extend to the two sides of the base along the first direction.

[0013] In one possible implementation, the inductor housing includes a cover and end caps that close both ends of the cover. The cover has a U-shaped cross-section, and the edge of the end caps is provided with a plurality of through holes spaced apart. The end of the cover is provided with screw holes aligned with the through holes.

[0014] In one possible implementation, one side of the end cap is provided with a folding plate that bends toward the bottom of the cover, and the folding plate is perpendicular to the end cap.

[0016] In one possible implementation, the length of the inductor housing is greater than the length of the fin assembly in a first direction, the height of the fin assembly is greater than the height of the inductor housing, and the width of the fin assembly in a second direction is greater than the width of the inductor housing in a second direction.

[0017] In one possible implementation, the end of the inductor housing near the fan is flush with or extends beyond the end of the fin assembly near the fan.

[0018] In one possible implementation, the protrusion is provided with a first heat sink, which is located on the upper end face and the side face of the protrusion. The first heat sink is arranged at equal intervals along the second direction and is in the shape of a sheet.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components.

They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0039] The terms "first," "second," "third," "fourth," etc. (if present) 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 of this application described herein can be implemented in orders other than those illustrated or described herein.

[0040] In this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions.

Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0041] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0042] An inverter, also known as an inverter device, is a device that can convert DC power into AC power with fixed frequency and voltage or adjustable frequency and voltage. It is widely used in power systems, industrial production, household electricity, and new energy fields.

[0043] In related technologies, an inverter includes a housing and a conversion component disposed inside the housing, wherein the conversion component is used to convert electrical energy. During operation, the conversion component converts low-voltage DC power into AC power that meets the demand and transmits it to the outside to power electrical equipment.

[0044] However, the conversion components generate heat during the energy conversion process, and if the heat cannot be dissipated in time, it can easily lead to heat accumulation inside the inverter.

[0045] Based on this, an embodiment of this application provides a housing assembly including a cover plate, a main body, a fin assembly, multiple protrusions, an inductor housing, and a fan. The cover plate, fin assembly, protrusions, and inductor housing are disposed on the main body. The fin assembly and inductor housing are located below the cover plate. The length of the inductor housing extends along a first direction, and the inductor housing is located on one side of the fin assembly in a second direction. The fan is located between the fin assembly and the protrusions. In the first direction, the air outlet of the fan faces the fin assembly, and the air inlet of the fan faces the protrusions. The first direction is perpendicular to the second direction.

[0046] When the inverter converts electrical energy, the conversion components inside the main body generate heat, which is then dissipated through the finned components in contact with it. When the fan is started, it circulates airflow outward. The airflow passes over the surface of the finned components, undergoes sufficient heat exchange with them, and is then discharged outside the main body, thus achieving the purpose of heat dissipation for the conversion components.

[0047] Compared to the structure of inverters in the prior art, the housing assembly provided in this application optimizes the heat dissipation efficiency of the conversion components and reduces the possibility of heat accumulation inside the inverter.

[0048] The technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0049] Reference Figures 1 to 3 As shown, this application provides a housing assembly including a cover plate 100, a main body 200, a fin assembly 300, a plurality of protrusions 400, an inductor housing 500, and a fan 600.

[0050] In a specific implementation, the conversion component is housed within the main body 200. The conversion component may include a main circuit unit and a control auxiliary unit. The main circuit unit can convert the input DC power (such as battery or photovoltaic panel output) into usable AC power through three steps of "switching-inverting-filtering" and transmit it to the outside to power electrical equipment. The control auxiliary unit is responsible for monitoring the status, adjusting parameters, and protecting the circuit to ensure that the main circuit operates efficiently and safely.

[0051] Meanwhile, the conversion component may also consist of only a main circuit unit or a control auxiliary unit. Operators can freely combine the specific structure of the conversion component according to actual usage requirements; these will not be elaborated upon here. In this embodiment, the conversion component is the main circuit unit.

[0052] The cover plate 100, fin assembly 300, protrusion 400 and inductor housing 500 are disposed on the main body 200.

[0053] It should be noted that in the embodiments of this application, the main body 200 is made of a material with good thermal conductivity, such as copper, aluminum, graphite, etc. In specific implementation, the conversion component is located inside the main body 200. The main body 200 has good thermal conductivity, which can improve the heat transfer efficiency between the main body 200 and the conversion component.

[0054] The fin assembly 300 and the inductor housing 500 are located below the cover plate 100, and the length of the inductor housing 500 is along the first direction (refer to...). Figure 2 The inductor housing 500 extends in the X direction of the fin assembly 300, and the inductor housing 500 is located in the second direction of the fin assembly 300 (refer to the X direction). Figure 2(on one side of the Y direction in the middle).

[0055] In practice, the cover plate 100 can cover the fin assembly 300 and the inductor housing 500, and has the function of waterproofing and dustproofing.

[0056] The fan 600 is located between the fin assembly 300 and the protrusion 400; in the first direction, the air outlet of the fan 600 faces the fin assembly 300, and the air inlet of the fan 600 faces the protrusion 400 (see specific airflow direction). Figure 2 (The arrow direction in the image); the first direction is perpendicular to the second direction.

[0057] In practice, the fin assembly 300 is disposed on the main body 200, and some of the heat on the main body 200 can be transferred to the fin assembly 300. When the inverter converts electrical energy, the conversion component disposed inside the main body 200 will generate heat, and the heat will be discharged in sequence through the main body 200 and the fin assembly 300 connected to the main body 200. The fan 600 is started, and the fan 600 circulates airflow to the outside. The airflow passes over the surface of the main body 200 and the fin assembly 300, and after sufficient heat exchange with the main body 200 and the fin assembly 300, it is discharged outside the main body 200, thereby achieving the purpose of heat dissipation for the conversion component.

[0058] Compared to the structure of inverters in the prior art, the housing assembly provided in this application optimizes the heat dissipation efficiency of the conversion components and reduces the possibility of heat accumulation inside the inverter.

[0059] Reference Figures 2 to 3 As shown, in some embodiments, the fin assembly 300 includes a base 310 and a plurality of heat dissipation fins 320. The heat dissipation fins 320 are in the shape of sheets and are perpendicularly connected to the base 310. The plurality of heat dissipation fins 320 are arranged in parallel and at equal intervals along a second direction. A heat dissipation channel 330 is formed between two adjacent heat dissipation fins 320. The two ends of the heat dissipation fins 320 extend to the two side edges of the base 310 along a first direction.

[0060] In practice, the heat sink fins 320 can be made of materials with good thermal conductivity, such as copper, aluminum, graphite, etc.

[0061] A heat dissipation channel 330 is formed between two adjacent heat dissipation fins 320, that is, the two ends of the heat dissipation channel 330 extend along the first direction to the two sides of the edge of the substrate 310.

[0062] The heat dissipation fins 320 extend along the first direction to the edges of the base 310, giving them a longer length on the base 310 and thus improving their heat dissipation efficiency. Of course, the number of heat dissipation fins 320 can be selected according to actual usage requirements, which will not be elaborated here.

[0063] During operation, the heat dissipation fins 320 serve both heat conduction and airflow guidance. Specifically, some of the heat on the main body 200 can be transferred to the base 310 and the heat dissipation fins 320. Secondly, after the fan 600 delivers airflow towards the heat dissipation fins 320, the airflow, guided by the heat dissipation channel 330, flows along the surface of the heat dissipation channel 330, i.e., the base 310 and the heat dissipation fins 320, so that the airflow carries away the heat from the base 310 and the heat dissipation fins 320. Simultaneously, because the heat dissipation fins 320 are vertically connected to the base 310, the airflow resistance of the heat dissipation fins 320 is low, allowing the airflow to flow smoothly within the heat dissipation channel 330.

[0064] Reference Figure 4 As shown, further, in some embodiments, the inductor housing 500 includes a cover 510 and end caps 520 that close both ends of the cover 510. The cover 510 has a U-shaped cross-section, and the edge of the end caps 520 is provided with a plurality of through holes 521 spaced apart. The end of the cover 510 is provided with screw holes 511 aligned with the through holes 521.

[0065] In a specific implementation, the inductor housing 500 protrudes from the main body 200 to surround the inductor protruding from the main body 200 and to dissipate heat from the inductor. There can be one or more inductors.

[0066] The inductor housing 500 is a key component in the inverter used to house and protect the inductor. It mainly plays the following roles: (1) to provide physical support and protection for the inductor, prevent the inductor from being damaged by external impacts, vibrations, etc., and ensure the stability of the inductor in the inverter; (2) to isolate the inductor from the external environment, avoid electrical short circuits between the inductor and other components, and ensure the electrical safety of the inverter; (3) the inductor will generate heat during operation. The inductor housing 500 can dissipate the heat through its own material and structural design to prevent the inductor from overheating and affecting its performance and lifespan.

[0067] Specifically, the U-shaped cover 510 has sufficient space to accommodate the inductor. The end cap 520 is connected to the screw hole 511 of the cover 510 via bolts passing through the through hole 521, enabling a detachable connection between the end cap 520 and the cover 510. During inductor installation, the inductor is inserted into the cover 510 from one end, and then the end cap 520 is installed to complete the inductor installation.

[0068] Reference Figure 4 As shown, in some embodiments, the end cap 520 is provided with a folding plate 522 that bends toward the bottom of the cover 510 on one side, and the folding plate 522 is perpendicular to the end cap 520.

[0069] In practice, after the inductor is installed on the cover 510, the cover 510 needs to be potted with potting compound, and the folding plate 522 can prevent the potting compound from flowing out from the edge of the end cover 520.

[0070] Reference Figure 2 and Figure 4 As shown, in some embodiments, the cover 510 is provided with second heat sinks 512 on both sides. The second heat sinks 512 extend along the first direction. The second heat sinks 512 on both sides of the cover 510 are symmetrically arranged. The second heat sinks 512 are perpendicular to the surface of the cover 510 and are sheet-shaped.

[0071] In a specific implementation, the second heat sink 512 is integrally connected with the cover 510, and two adjacent second heat sinks 512 and the cover 510 together form an air guide channel; the cover 510 can be made of a material with good thermal conductivity, such as copper, aluminum, graphite, etc.

[0072] The second heat sink 512 serves both heat conduction and airflow guidance. Specifically, some of the heat on the inductor housing 500 can be transferred to the second heat sink 512. After the fan 600 delivers airflow towards the inductor housing 500, the airflow will flow along the airflow channel, i.e., the surface of the cover 510 and the second heat sink 512, under the guidance of the airflow channel, so that the airflow can carry away the heat in the cover 510 and the second heat sink 512. Finally, the airflow, along with the absorbed heat, is discharged to the outside of the main body 200. The setting of the second heat sink 512 can increase the heat dissipation area of ​​the cover 510, thereby improving the overall heat dissipation efficiency of the inductor housing 500.

[0073] In some embodiments, the length of the inductor housing 500 is greater than the length of the fin assembly 300 in the first direction, the height of the fin assembly 300 is greater than the height of the inductor housing 500, and the width of the fin assembly 300 in the second direction is greater than the width of the inductor housing 500 in the second direction.

[0074] In some embodiments, the end of the inductor housing 500 near the fan 600 is flush with or extends beyond the end of the fin assembly 300 near the fan 600.

[0075] In practical implementation, the inductor housing 500, after ensuring it can accommodate the required inductor, has a relatively long length to increase the heat dissipation area and improve heat dissipation efficiency. The height of the fin assembly 300 is greater than the height of the inductor housing 500, resulting in a higher height for the heat dissipation fins 320 and a larger heat dissipation area. The end of the inductor housing 500 near the fan 600 is flush with or extends beyond the end of the fin assembly 300 near the fan 600, preventing airflow from flowing to the side of the inductor housing 500 away from the fin assembly 300, thus concentrating the airflow across the fin assembly 300. This effect is particularly pronounced when the end of the inductor housing 500 near the fan 600 extends beyond the end of the fin assembly 300 near the fan 600.

[0076] Reference Figure 1 and Figure 2 As shown, in some embodiments, the protrusion 400 is provided with a first heat sink 410, which is located on the upper end surface and the side surface of the protrusion 400. The first heat sink 410 is arranged at equal intervals along the second direction and is in the shape of a sheet.

[0077] It should be noted that in the above embodiments, the protrusion 400 can be made of a material with good thermal conductivity, such as copper, aluminum, graphite, etc. In specific implementation, the protrusion 400 is used to be arranged opposite to the functional device, and it is in contact with the surface of the functional device. The protrusion 400 has good thermal conductivity, which can improve the heat transfer efficiency between the protrusion 400 and the functional device.

[0078] Meanwhile, the protrusion 400 not only provides physical support and protection for the functional devices, preventing them from being damaged by external impacts or vibrations, and ensuring the stability of the functional devices in the inverter; at the same time, the functional devices generate heat during operation, and the protrusion 400 can dissipate the heat through its own material and structural design, preventing the functional devices from overheating and affecting their performance and lifespan.

[0079] Of course, staff can select the number of the first heat sink 410 according to actual usage needs, which will not be elaborated here.

[0080] The first heat sink 410 has the functions of heat conduction and airflow guidance. Specifically, some of the heat on the protrusion 400 can be transferred to the first heat sink 410. Secondly, when the fan 600 circulates airflow to the outside, the airflow will first flow along the surface of the protrusion 400 and the first heat sink 410 so that the airflow can carry away the heat in the protrusion 400 and the first heat sink 410. Then the airflow will exchange heat with the main body 200 and the heat sink 320. Finally, the airflow along with the absorbed heat will be discharged to the outside of the main body 200, so as to have a better heat dissipation effect on the functional device and high heat dissipation efficiency.

[0081] Reference Figure 1 , Figure 2 and Figure 5 As shown, in some embodiments, a mounting plate 700 is also included, which is located between the fin assembly 300 and the protrusion 400. The length direction of the mounting plate 700 is parallel to the second direction. There are multiple fans 600, which are arranged sequentially and at intervals on the mounting plate 700 along the second direction.

[0082] Furthermore, in some embodiments, the mounting plate 700 is provided with a ventilation section 710, and the ventilation section 710 and the fan 600 are spaced apart on the mounting plate 700; the ventilation section 710 is provided with a plurality of ventilation openings 711.

[0083] Furthermore, in some embodiments, the mounting plate 700 is detachably connected to the mounting bracket 800 and / or the body 200.

[0084] In practical implementation, the fan 600 is configured as a fan, and the number of fans is set to two. The fans can accelerate the airflow, thereby improving the heat exchange efficiency between the airflow and the heat sink 320, the first heat sink 410, and the second heat sink 512. Of course, the number of fans can be set to three or even more, which will not be elaborated here.

[0085] The fan has ventilation sections 710 on both sides, each ventilation section having multiple vents 711. The design of multiple vents 711 facilitates the rapid flow of air into the main body 200 for heat exchange with the fin assembly 300.

[0086] Meanwhile, the fan 600 is mounted on the mounting plate 700. In this embodiment, the mounting plate 700 may be detachably connected only to the mounting bracket 800. In other embodiments, the mounting plate 700 may be detachably connected only to the main body 200, or the mounting plate 700 may be detachably connected to both the mounting bracket 800 and the main body 200. After long-term use, the fan 600 is prone to failure. In this embodiment, the detachable connection between the mounting plate 700 and the mounting bracket 800 allows maintenance personnel to easily remove the mounting plate 700 to replace the damaged fan 600.

[0087] In this embodiment, the end of the inductor housing 500 near the fan 600 is flush with the end of the fin assembly 300 near the fan 600, and the end of the inductor housing 500 near the fan 600 and the end of the fin assembly 300 near the fan 600 are located on the same side of the mounting plate 700. In some embodiments, when the end of the inductor housing 500 near the fan 600 extends beyond the end of the fin assembly 300 near the fan 600, the end of the inductor housing 500 near the fan 600 can pass through the mounting plate 700, and the mounting plate 700 has an opening through which the inductor housing 500 passes.

[0088] Reference Figure 1 and Figure 2 As shown, in some embodiments, a mounting bracket 800 is further included, which is disposed on the outside of the fin assembly 300.

[0089] The mounting bracket 800 is equipped with a heat dissipation unit, and the fan 600 and the heat dissipation unit are arranged opposite each other along the first direction; the heat dissipation unit is equipped with multiple heat dissipation vents, which helps the airflow after absorbing heat to be quickly discharged to the outside of the main body 200.

[0090] In specific implementations, the height of the mounting bracket 800 is limited to be higher than the height of the fin assembly 300 to avoid interference between the cover plate 100 and the fin assembly 300 during installation. The cover plate 100 and the mounting bracket 800 are detachably connected by bolts. In some embodiments, the cover plate 100 and the mounting bracket 800 are connected before subsequent installation, fixing the cover plate 100 in the corresponding installation position. In other embodiments, the cover plate 100 can be fixed in the installation position first, and then the mounting bracket 800 and the cover plate 100 can be connected by bolts to achieve overall installation and fixation. In still other embodiments, the cover plate 100 may not be installed when the inverter is in use.

[0091] This application also provides an inverter, including the housing assembly of any of the above embodiments.

[0092] The housing components in this application embodiment have the same structure as the housing components provided in any of the above embodiments, and can bring the same or similar technical effects.
