In the description of the embodiments of the present application, the meaning of "plurality" is two or more unless explicitly defined otherwise.

It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present. In the present application, unless explicitly specified and limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the terms in this application will be understood by those of ordinary skill in the art as the case may be.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The terms "comprising" and "having" and any variations thereof, in the description and claims of the present application and in the description of the figures above, are intended to cover non-exclusive inclusions.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present application. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.

In the related art, an inverter includes a housing, an inverter module and a connector, the inverter module is disposed inside the housing, the connector is disposed at one side of the housing, and the connector is electrically connected to the inverter module.

The connector may be a connection socket. External devices such as an energy storage power supply, a photovoltaic panel and the like are provided with connecting plugs which are matched with the connectors, and the external devices are plugged into the connectors through the connecting plugs so as to be electrically connected with the inverter.

After the connection plug is plugged into the connector, a detacher is typically used when the user needs to detach the connection plug. When the disassembling device is used, a user can extend the disassembling device into a gap between the connecting plug and the connector, then apply force to the disassembling device, enable the disassembling device to be abutted between the connecting plug and the connector, and eject the connecting plug from the connector.

However, the disassembling device is inconvenient to store after use, easy to lose, and the disassembling device is usually small in size, difficult to find after losing, and influences user experience.

Therefore, the embodiment of the application provides a heat shield, heat shield combination equipment and inversion equipment, which can solve the problem that a disassembling device is easy to lose.

Referring to fig. 1 and 2, an embodiment of the present application provides a heat shield 100, and the heat shield 100 may be applied to an inverter 300 and a disassembler 200. The inverter 300 has a connector 301 for connecting to an external device. The external device is provided with a connecting plug which is matched with the connector, and the external device is plugged into the connector through the connecting plug so as to enable the external device to be electrically connected with the inverter. The detacher 200 is used to separate an external device connected to the connector 301 from the connector 301.

Referring to fig. 3 and 4, the heat shield 100 includes a shield body 10 and a limiting portion 20, wherein the shield body 10 is provided with a receiving cavity 11, and the receiving cavity 11 can receive the inverter 300. The limiting portion 20 is disposed on the cover 10, and the limiting portion 20 is used for detachably limiting the disassembling device 200. When the limiting part 20 limits the disassembling device 200 on the cover body 10, the disassembling device 200 is relatively fixed with the cover body 10; when the detacher 200 is separated from the stopper 20, the detacher 200 is separated from the housing 10.

It will be appreciated that heat is generated when the inverter 300 is in operation, and the heat is dissipated from the interior of the inverter 300 to the external environment through the housing 302, so that the housing 302 may be scalded, especially when the human body directly contacts the housing 302, due to the metal housing 302. By accommodating the inverter 300 in the accommodating cavity 11, the whole cover body 10 is covered on the inverter 300, thereby playing a role of heat insulation for the inverter 300, blocking direct contact between a human body and the shell 302 and avoiding scalding of the human body by the inverter 300 in a working state.

Referring to fig. 4, when the external device is not required to be separated from the connector 301 by the detacher 200, the detacher 200 may be limited to the housing 10 by the limiting part 20, and the detacher 200 may be accommodated. When the external device is required to be separated from the connector 301 by using the detacher 200, the detacher 200 may be detached from the stopper 20 and reused, and the detacher 200 may be restricted to the cover 10 again after use, and the detacher 200 may be stored again.

According to the embodiment of the application, the limiting part 20 is arranged on the cover body 10 of the heat shield 100, so that the heat insulation effect on the inverter 300 can be achieved, the disassembling device 200 can be conveniently stored on the one hand, the disassembling device 200 is not easy to lose, the heat shield 100 is integrated with heat insulation and storage functions, the practicability is higher, and the use is more convenient.

In one embodiment of the present application, the cover 10 is a single structure, and the cover 10 includes a panel 30 and a shroud 40, and the limiting portion 20 is disposed on the panel 30. The shroud 40 is fixed to the panel 30, the shroud 40 is disposed around the panel 30, and the shroud 40 is perpendicular to the panel 30, and a space capable of accommodating the inverter 300 is formed between the shroud 40 and the panel 30, so that the shroud 40 and the panel 30 together define the accommodating chamber 11.

The other side of the coaming 40 opposite to the panel 30 is formed with a cavity opening 12 communicating with the accommodating cavity 11, and the size of the cavity opening 12 is adapted to the size of the inverter 300, and the cover body 10 can be conveniently covered on the inverter 300 through the cavity opening 12. When the inverter 300 is accommodated in the accommodating cavity 11 (i.e. when the cover body 10 covers the inverter 300), the panel 30 may be disposed on a side of the inverter 300 away from the fixture, and the surrounding plate 40 may be disposed around the periphery of the inverter 300, so that the cover body 10 can insulate the inverter 300 in multiple directions.

It is understood that the fixture refers to an object for placing the inverter 300, such as a bracket for hanging the inverter 300, a table for placing the inverter 300 flat, and the like.

In some embodiments, the area of the panel 30 is larger than the area of the inverter 300 on the side away from the fixture, so that the accommodating chamber 11 can provide enough space to accommodate the inverter 300.

It is understood that the shape of the panel 30 or the shroud 40 may be set according to the shape of the housing of the inverter 300. In one example of the present embodiment, the whole of the housing 302 of the inverter 300 is a cuboid, and the edges of the housing 302 are rounded, so that the panel 30 is a rectangular plate, and four corners of the rectangle are rounded, and the coaming 40 is distributed along the edge profile of the panel 30; in other examples, if the shape of the housing 302 of the inverter 300 is changed, the panel 30 or the shroud 40 may be adapted, which is not limited in this application.

In some embodiments, the shroud 40 is provided with a communication port 41, the communication port 41 being provided corresponding to a side of the inverter 300 where the connector 301 is provided, the communication port 41 penetrating the shroud 40 and communicating with the accommodation chamber 11. When the inverter 300 is accommodated in the accommodation chamber 11, the connector 301 is exposed to the shroud 40 through the communication port 41, so that the connector 301 can be connected to a connection plug of an external device.

In some embodiments, the cover 10 is made of a thermally insulating material, including but not limited to fiberglass, asbestos, rock wool, silicate, etc., such that the heat shield 100 itself is not readily thermally conductive, preventing scalding of the heat shield 100.

In some embodiments, the panel 30 is provided with a plurality of first heat dissipation holes 31, the plurality of first heat dissipation holes 31 are distributed at intervals, and the first heat dissipation holes 31 penetrate through the panel 30. The shroud 40 is provided with a plurality of second heat dissipation holes 42, the plurality of second heat dissipation holes 42 are spaced apart, and the second heat dissipation holes 42 extend along the peripheral side of the shroud 40.

It can be appreciated that the heat inside the heat shield 100 can be dissipated outside the accommodating cavity 11 through the first heat dissipation holes 31 and the second heat dissipation holes 42, so as to accelerate the heat dissipation efficiency of the heat generated by the inverter 300 to the outside of the heat shield 100, make the panel 30 not easy to burn, reduce the heat accumulation inside the accommodating cavity 11, and reduce the influence of the continuous high temperature on the working performance of the inverter 300.

In one embodiment of the present application, the cover 10 further includes a plurality of supporting protrusions 33, the plurality of supporting protrusions 33 are disposed on a side of the panel 30 facing the accommodating cavity 11, and the plurality of supporting protrusions 33 are spaced apart. One end of the supporting protrusion 33 is fixed to the panel 30, and the other end is for abutting against the inverter 300.

When the inverter 300 is accommodated in the accommodating cavity 11, the supporting protrusion 33 abuts against the inverter 300, so that on one hand, the panel 30 is supported, and the installation stability of the heat shield 100 is improved; on the other hand, the support protrusions 33 space the panel 30 and the inverter 300 from each other, even if a certain space is maintained between the panel 30 and the case 302, the direct contact between the panel 30 and the case 302 is reduced, and thus the heat transfer from the case 302 to the panel 30 is reduced, so that the panel 30 is not easily scalded.

It will be appreciated that the support protrusion 33 corresponds to a minimum distance between the panel 30 and the inverter 300, and the interval distance between the panel 30 and the inverter 300 can be adjusted by changing the length of the support protrusion 33, and the interval distance can be adjusted according to the actual demand of the heat dissipation amount, which is not limited in this application.

In some embodiments, the number of support protrusions 33 is 3 or more. The number of the supporting projections 33 in the present embodiment is exemplified by 16, and a plurality of supporting projections 33 are distributed in an array.

When the inverter 300 is accommodated in the accommodating cavity 11, the at least three supporting protrusions 33 are simultaneously contacted with the inverter 300, so that the panel 30 has at least three contact points relative to the inverter 300, the interval between the panel 30 and the inverter 300 is more stable, the interval space between the panel 30 and the inverter 300 is maintained, and the heat dissipation stability is improved.

In some embodiments, the supporting protrusions 33 are located between the respective first heat dissipation holes 31, and a space is provided between the supporting protrusions 33 and the adjacent first heat dissipation holes 31 such that the supporting protrusions 33 and the first heat dissipation holes 31 do not interfere with each other, preventing the supporting protrusions 33 from blocking the first heat dissipation holes 31.

In some embodiments, the second louvers 42 are disposed on a side of the shroud 40 proximate to the panel 30. When the inverter 300 is accommodated in the accommodating cavity 11, the second heat dissipation holes 42 communicate the space between the panel 30 and the inverter 300 with the external space of the accommodating cavity 11, so that the heat dissipation efficiency of the space between the panel 30 and the inverter 300 is improved, and the panel 30 is not easy to burn.

In one embodiment of the present application, the cover 10 further includes a plurality of supporting ribs 43, where the plurality of supporting ribs 43 are disposed on a side of the coaming 40 facing the accommodating cavity 11, and the plurality of supporting ribs 43 are arranged at intervals along a circumference of the panel 30, that is, the plurality of supporting ribs 43 are arranged at intervals along a surface of the coaming 40.

When the inverter 300 is accommodated in the accommodating cavity 11, the supporting ribs 43 are propped against the inverter 300, and the plurality of supporting ribs 43 are simultaneously propped against the side edge of the inverter 300, so that the coaming 40 is supported on one side, and the installation stability of the heat shield 100 is improved; on the other hand, the supporting ribs 43 enable the coaming 40 and the inverter 300 to be spaced from each other, even if a certain spacing distance is maintained between the coaming 40 and the housing 302, direct contact between the coaming 40 and the housing 302 is reduced, and heat transfer from the housing 302 to the coaming 40 is further reduced, so that the coaming 40 is not easy to scald.

In some embodiments, the supporting ribs 43 extend along the width direction of the coaming 40 to be arranged in a strip shape, so that on one hand, the structural stability of the coaming 40 is enhanced, and on the other hand, the contact area of the supporting ribs 43 abutting against the inverter 300 is increased, so that the mutual abutting between the supporting ribs 43 and the inverter 300 is more stable, and the installation stability of the heat shield 100 is improved.

In some embodiments, the support ribs 43 are arranged in pairs, each pair of support ribs 43 includes two support ribs 43 spaced apart from each other and parallel to each other, and a plurality of pairs of support ribs 43 are spaced apart from each other. When the inverter 300 is accommodated in the accommodating cavity 11, each pair of supporting ribs 43 abuts against the inverter 300, so that the coaming 40 has at least two contact points relative to the inverter 300, the interval between the coaming 40 and the inverter 300 is more stable, the interval space between the coaming 40 and the inverter 300 is maintained, and the heat dissipation stability is improved.

In some embodiments, one end of the supporting rib 43 is fixedly connected to the panel 30, and the supporting rib 43 is simultaneously fixedly connected to the coaming 40 and the panel 30, so as to enhance the connection stability between the coaming 40 and the panel 30, thereby improving the structural strength of the cover 10.

In one embodiment of the present application, the cover 10 is detachably connected to the inverter 300, and the accommodating chamber 11 detachably accommodates the inverter 300. The limiting part 20 is located in the accommodating cavity 11, and the limiting part 20 is disposed at one side of the panel 30 close to the accommodating cavity 11.

When the inverter 300 is accommodated in the accommodating cavity 11, the limiting portion 20 can limit the disassembling device 200 to the inside of the accommodating cavity 11, so that the disassembling device 200 is hidden and accommodated in the cover body 10, and the appearance consistency of the heat shield 100 is improved. In addition, when the disassembler 200 falls off the panel 30 by itself due to accident, the disassembler 200 can be retained in the accommodating cavity 11, so as to reduce the risk of losing the disassembler 200.

When it is necessary to separate the external device from the connector 301 by using the detacher 200, the cover 10 may be detached from the inverter 300, and then the detacher 200 may be detached from the stopper 20 and reused. After use, the disassembling device 200 can be limited on the cover body 10 again, and the heat shield 100 is arranged on the inverter 300, so that the inverter 300 is fixed in the accommodating cavity 11 again, and the disassembling device 200 is accommodated again.

It will be appreciated that when the inverter 300 is accommodated in the accommodating chamber 11 and the inverter 300 needs to be disassembled, the inverter 300 can be pulled out from the cavity opening 12 of the accommodating chamber 11, so that the inverter 300 is separated from the cover 10. When the inverter 300 needs to be mounted in the accommodating cavity 11, the cavity opening 12 of the inverter 300 can be pushed into the accommodating cavity 11, and the plurality of supporting ribs 43 are abutted against the inverter 300, so that the inverter 300 and the cover 10 are relatively fixed.

In one use scenario, the inverter 300 is placed on a table in a horizontal direction, the cover body 10 is covered on the inverter 300, the disassembling device 200 is accommodated in the accommodating cavity 11, when the disassembling device 200 needs to be used, the cover body 10 can be pulled out from the inverter 300, the inverter 300 is separated from the cover body 10, and then the disassembling device 200 is taken out from the panel 30; after the disassembling device 200 is used, the disassembling device 200 can be limited on the panel 30, then the cover body 10 is covered on the inverter 300 and pushes the cover body 10, so that the inverter 300 is accommodated in the accommodating cavity 11, and the plurality of supporting ribs 43 are abutted against the inverter 300, so that the inverter 300 and the cover body 10 are relatively fixed, and the installation of the heat insulation cover 100 and the accommodation of the disassembling device 200 are completed again.

It can be appreciated that the embodiment of the present application detachably connects the inverter 300 and the heat shield 100 by the mutual abutment between the plurality of supporting ribs 43 and the inverter 300. In some possible embodiments, the removable connection between the heat shield 100 and the inverter 300 may also include, but is not limited to, clamping, bolting, etc., which is not limited in this application.

Referring to fig. 3 and 4, in an embodiment of the present application, the limiting portion 20 includes a first limiting portion 21 and a second limiting portion 22, and the first limiting portion 21 and the second limiting portion 22 are disposed at intervals between each other to form a limiting space 23 for accommodating the disassembling device 200, and the first limiting portion 21 and the second limiting portion 22 are distributed around the limiting space 23.

When the disassembling device 200 is accommodated in the limiting space 23, the first limiting parts 21 and the second limiting parts 22 are distributed around the disassembling device 200, the first limiting parts 21 limit the disassembling device 200 along the first direction, the second limiting parts 22 limit the disassembling device 200 along the second direction, and an included angle is formed between the first direction and the second direction so as to limit and fix the disassembling device 200.

It can be appreciated that the first limiting portion 21 and the second limiting portion 22 can limit the disassembling device 200 from different directions, so that the disassembling device 200 can be more stably fixed on the cover 10, and is not easy to fall off.

In some embodiments, the angle between the first direction and the second direction is 90 °. The first limiting part 21 and the second limiting part 22 can be matched to limit the disassembling device 200 in two directions perpendicular to each other, so that the limiting stability of the disassembling device 200 is improved.
