Description

Technical Field

[0001] The utility model relates to the technical field of inverters, and in particular to an inductor box component and an energy storage inverter. Background Art

[0002] Currently, energy storage inverters in related technologies require the simultaneous installation of an inductor and a transformer. This increases the overall size of the inverter, hindering its miniaturization. Furthermore, because both the inductor and transformer are connected via lead wires, installing them separately requires multiple wire routing and placement, a cumbersome process.

[0003] Therefore, how to design an inductor box assembly that can reduce the overall volume of the energy storage inverter and is easy to install has become a problem that needs to be solved urgently. Utility Model Content

[0004] The utility model aims to at least solve the problems of the energy storage inverter being large in overall size and inconvenient to install.

[0005] To this end, a first aspect of the present invention provides an inductor box assembly.

[0006] A second aspect of the present invention provides an energy storage inverter.

[0007] In view of this, the first aspect of the present invention proposes an inductor box assembly for an energy storage inverter, the inductor box assembly comprising: a box body, the box body comprising an installation cavity; a partition, arranged in the installation cavity, for dividing the installation cavity into a first cavity and a second cavity; an inductor assembly, arranged in the first cavity, for being electrically connected to the energy storage inverter; and a transformer, arranged in the second cavity, for being electrically connected to the energy storage inverter.

[0008] The inductor box assembly provided by the present invention can be used in an energy storage inverter. The inductor box assembly includes a box body, a partition, an inductor assembly and a transformer. The box body includes an installation cavity, and the partition is arranged in the installation cavity to separate the installation cavity into a first cavity and a second cavity, so that the inductor assembly and the transformer can be installed in different cavities to ensure that the inductor assembly and the transformer do not interfere with each other. Since the present application sets both the transformer and the inductor assembly in one box body, when installing the inductor assembly and the transformer, it is only necessary to install the inductor box assembly as a whole with the energy storage inverter, and then electrically connect it to the energy storage inverter. There is no need to install the inductor assembly and the transformer again and again, which improves assembly efficiency and saves time. At the same time, since the transformer and the inductor assembly are arranged in one box body, compared with setting the transformer and the inductor assembly separately, the present application reduces the overall volume of the energy storage inverter, which is conducive to the miniaturization development of the energy storage inverter.

[0009] The inductor box assembly provided by the present invention may also have the following additional technical features:

[0010] In some embodiments, optionally, the inductor box assembly further includes: a second circuit board fixedly mounted on the box body, connected to the inductor assembly and / or the transformer, and configured to be connected to the energy storage inverter.

[0011] In these embodiments, a second circuit board can be provided to connect to the inductor assembly and / or transformer, and then the second circuit board can be fixedly mounted on the housing. This allows electrical connection to the energy storage inverter via the second circuit board. It is understandable that the inductor assembly and transformer lead to a large number of connecting wires, and these wires need to be connected to different locations on the energy storage inverter. Therefore, if the wires are directly connected to the energy storage inverter, the wiring inside the energy storage inverter housing will be very complicated. However, the present application can further simplify the connection to the energy storage inverter by providing an additional second circuit board. During installation, it is only necessary to first connect the connecting wires of the inductor assembly and / or transformer to the second circuit board, and then use the second circuit board to connect to the energy storage inverter. Connecting the energy storage inverter via the circuit board avoids the use of messy wires. For example, conductive posts can be provided between the second circuit board and the circuit board of the energy storage inverter for connection, or terminal blocks can be provided on both circuit boards for connection, or conductive posts can be provided on one circuit board and terminal blocks can be provided on the other circuit board for connection.

[0012] In some embodiments, optionally, the inductor box assembly further includes: a conductive column, disposed on the second circuit board and electrically connected to the energy storage inverter.

[0013] In these embodiments, conductive posts can be provided on the second circuit board to abut the energy storage inverter, thereby achieving electrical connection between the energy storage inverter and the second circuit board. It is understood that during installation, the conductive posts on the second circuit board can be directly abutted against the solder on the energy storage inverter circuit board to achieve electrical connection between the two. This installation method is simple, requiring only a fixed mounting position to be set and then directly aligned during installation, improving installation efficiency.

[0014] In some embodiments, optionally, the conductive pillar includes a plurality of conductive pillars, and the plurality of conductive pillars have the same height.

[0015] In some embodiments, optionally, a connection terminal may be provided on the second circuit board, and an electrical connection may be established with the energy storage inverter through the connection terminal.

[0016] In some embodiments, optionally, the second circuit board is connected to the inductor component.

[0017] In some embodiments, optionally, the second circuit board is connected to the transformer, and the second circuit board is soldered to the transformer.

[0018] In some embodiments, optionally, the inductor box assembly further includes: a support column, disposed between the second circuit board and the box body, for fixing and supporting the second circuit board on the box body.

[0019] In these embodiments, in order to facilitate the fixed installation of the second circuit board and achieve a stable connection between the second circuit board and the energy storage inverter, a support column can be set between the second circuit board and the box body, and the second circuit board can be fixedly supported on the box body by the support column. In this way, during installation, the second circuit board can be connected to the energy storage inverter by a hard connection. For example, the second circuit board and the circuit board of the energy storage inverter are directly abutted together through the conductive column.

[0020] In some embodiments, optionally, the support column can limit the second circuit board outside the installation cavity, which is convenient for connection with the energy storage inverter.

[0021] In some embodiments, optionally, at least a portion of the second circuit board is disposed outside the mounting cavity.

[0022] In these embodiments, disposing at least a portion of the second circuit board outside the mounting cavity can avoid fixing the second circuit board together with the inductor assembly and / or transformer, thereby affecting the connection with the energy storage inverter.

[0023] In some embodiments, optionally, the inductor box assembly further includes: a potting compound disposed in the mounting cavity for fixing the inductor assembly and the transformer.

[0024] In these embodiments, the inductor assembly and the transformer can be fixed and installed using potting compound, thereby effectively dissipating the heat generated by the components through the potting compound's much higher thermal conductivity than air and the heat dissipation capability of the box.

[0025] In some embodiments, optionally, the housing is a metal housing.

[0026] In some embodiments, optionally, the box body is an aluminum box body.

[0027] In some embodiments, optionally, the inductor box assembly further includes: a heat dissipation assembly, disposed outside the box body, for dissipating heat generated by the inductor assembly and the transformer.

[0028] In these embodiments, a heat dissipation component may be provided outside the box body to dissipate heat, thereby further improving the overall heat dissipation effect of the inductor box assembly.

[0029] In some embodiments, optionally, the heat dissipation assembly includes: a plurality of first heat dissipation fins arranged at intervals along the height direction of the box body; and a plurality of second heat dissipation fins arranged at intervals along the width direction of the box body.

[0030] In these embodiments, heat can be dissipated through a plurality of heat dissipation fins arranged at intervals, thereby improving the heat dissipation efficiency of the inductor box assembly.

[0031] In some embodiments, optionally, an installation port is provided on the box body, and the installation port is connected to the installation cavity. The inductor box assembly also includes: an installation groove, provided at the installation port; and a sealing member, provided in the installation groove, for sealing the connection between the inductor box assembly and the energy storage inverter.

[0032] In these embodiments, a mounting groove can be provided at the mounting opening of the box body, and then a seal can be provided in the mounting groove. In this way, when the inductor box assembly is installed, the connection between the inductor box assembly and the energy storage inverter can be sealed by the seal, thereby preventing dust from entering the interior of the energy storage inverter.

[0033] The second aspect of the present invention proposes an energy storage inverter, comprising: an inverter case; a first circuit board, arranged in the inverter case; an inductor box assembly such as any technical solution in the first aspect, installed on the inverter case and electrically connected to the first circuit board.

[0034] The energy storage inverter provided in this application includes an inverter housing, a first circuit board, and the inductor box assembly of any technical solution of the first aspect. The first circuit board is disposed within the inverter housing, and the inductor box assembly is mounted on the inverter housing and electrically connected to the first circuit board. Since the energy storage inverter provided in this application includes the inductor box assembly of any technical solution of the first aspect, the energy storage inverter provided in this application also has all the beneficial effects of the inductor box assembly of any technical solution of the first aspect, which will not be repeated here.

[0035] In some embodiments, optionally, a connection port is provided on the inverter housing, and the inductor box assembly includes a conductive column, which passes through the connection port and abuts against the first circuit board.

[0036] In these embodiments, a connection port can be provided on the inverter, and a conductive post can be passed through the connection port to abut against the first circuit board, thereby achieving electrical connection between the inductor box assembly and the first circuit board. It can be understood that since the present application can achieve electrical connection by abutting the conductive post against the first circuit board, compared to solutions using wires or providing terminal blocks, the present application can make installation of the inductor box assembly more convenient.

DETAILED DESCRIPTION

[0051] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0052] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0053] Refer to the following Figures 1 to 10 An inductor box assembly and an energy storage inverter according to some embodiments of the present invention are described.

[0054] According to an embodiment of the first aspect of the present invention, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, the first aspect of the present invention provides an inductor box assembly 10 for an energy storage inverter 20. The inductor box assembly 10 includes a box body 100, a partition 101, an inductor assembly 102, and a transformer 103. The box body 100 includes a mounting cavity 1002. The partition 101 is disposed in the mounting cavity 1002 to separate the mounting cavity 1002 into a first cavity 1004 and a second cavity 1006. The inductor assembly 102 is disposed in the first cavity 1004 to be electrically connected to the energy storage inverter 20. The transformer 103 is disposed in the second cavity 1006 to be electrically connected to the energy storage inverter 20.

[0055] The inductor box assembly 10 provided by the present invention can be used for the energy storage inverter 20. The inductor box assembly 10 includes a box body 100, a partition 101, an inductor assembly 102 and a transformer 103. The box body 100 includes an installation cavity 1002, and the partition 101 is arranged in the installation cavity 1002, dividing the installation cavity 1002 into a first cavity 1004 and a second cavity 1006, so that the inductor assembly 102 and the transformer 103 can be installed in different cavities to ensure that the inductor assembly 102 and the transformer 103 do not interfere with each other. Since the present application arranges the transformer 103 and the inductor assembly 102 in one box body 100, when installing the inductor assembly 102 and the transformer 103, it is only necessary to install the inductor box assembly 10 as a whole with the energy storage inverter 20, and then electrically connect it to the energy storage inverter 20. There is no need to install the inductor assembly 102 and the transformer 103 again and again, which improves assembly efficiency and saves time. At the same time, since the transformer 103 and the inductor assembly 102 are arranged in a box body 100, compared with separately arranging the transformer 103 and the inductor assembly 102, the present application reduces the overall volume of the energy storage inverter 20, which is conducive to the miniaturization development of the energy storage inverter 20.

[0056] In some embodiments, optionally, the inductor box assembly 10 further includes: a second circuit board 104 fixedly mounted on the box body 100 , connected to the inductor assembly 102 and / or the transformer 103 , and configured to be connected to the energy storage inverter 20 .

[0057] In these embodiments, a second circuit board 104 may be provided to connect to the inductor assembly 102 and / or the transformer 103, and then the second circuit board 104 may be fixedly mounted on the box body 100, so that the second circuit board 104 can be used to electrically connect to the energy storage inverter 20. It is understood that the inductor assembly 102 and the transformer 103 have many connecting wires, and they need to be connected to different locations of the energy storage inverter 20. Therefore, if the wires are directly connected to the energy storage inverter 20, the wiring inside the energy storage inverter 20 box will be very complicated. However, the present application can make the connection to the energy storage inverter 20 simpler by providing an additional second circuit board 104. During installation, it is only necessary to first connect the connecting wires of the inductor assembly 102 and / or the transformer 103 to the second circuit board 104, and then use the second circuit board 104 to connect to the energy storage inverter 20. The connection is made through circuit boards, avoiding the use of messy wires. For example, a conductive column 105 can be set between the second circuit board 104 and the circuit board of the energy storage inverter 20 for connection, or wiring terminals can be set on the two circuit boards for connection, or a conductive column 105 can be set on one circuit board and a wiring terminal can be set on the other circuit board for connection.

[0058] In some embodiments, optionally, the inductor box assembly 10 further includes: a conductive column 105 , which is disposed on the second circuit board 104 and electrically connected to the energy storage inverter 20 .

[0059] In these embodiments, conductive posts 105 can be provided on the second circuit board 104 to abut the energy storage inverter 20, thereby achieving electrical connection between the energy storage inverter 20 and the second circuit board 104. It is understood that during installation, the conductive posts 105 on the second circuit board 104 can be directly abutted against the solder on the circuit board of the energy storage inverter 20 to achieve electrical connection between the two. This installation method is simple, requiring only a fixed installation position to be set and then directly aligned during installation, thereby improving installation efficiency.

[0060] In some embodiments, optionally, the conductive pillar 105 includes a plurality of conductive pillars 105 , and the heights of the plurality of conductive pillars 105 are the same.

[0061] In some embodiments, optionally, a connection terminal may be provided on the second circuit board 104 , and an electrical connection may be established with the energy storage inverter 20 through the connection terminal.

[0062] In some embodiments, optionally, the second circuit board 104 is connected to the inductor assembly 102 .

[0063] In some embodiments, optionally, the second circuit board 104 is connected to the transformer 103 , and the second circuit board 104 is soldered to the transformer 103 .

[0064] In some embodiments, optionally, as Figure 2 and Figure 3 As shown, the inductor box assembly 10 further includes a support column 106 , which is disposed between the second circuit board 104 and the box body 100 and is used to fix and support the second circuit board 104 on the box body 100 .

[0065] In these embodiments, in order to facilitate the fixed installation of the second circuit board 104 and achieve a stable connection between the second circuit board 104 and the energy storage inverter 20, a support column 106 can be set between the second circuit board 104 and the box body 100, and the second circuit board 104 is fixedly supported on the box body 100 by the support column 106. In this way, during installation, the second circuit board 104 can be connected to the energy storage inverter 20 by a hard connection. For example, the second circuit board 104 and the circuit board of the energy storage inverter 20 are directly abutted together through the conductive column 105.

[0066] In some embodiments, optionally, the support column 106 can limit the second circuit board 104 outside the installation cavity 1002 , which is beneficial for connection with the energy storage inverter 20 .

[0067] In some embodiments, optionally, at least a portion of the second circuit board 104 is disposed outside the mounting cavity 1002 .

[0068] In these embodiments, disposing at least a portion of the second circuit board 104 outside the mounting cavity 1002 can avoid fixing the second circuit board 104 together when fixing the inductor assembly 102 and / or the transformer 103 , thereby affecting the connection with the energy storage inverter 20 .

[0069] In some embodiments, optionally, as Figure 2 As shown, the inductor box assembly 10 further includes: a potting compound 107 disposed in the mounting cavity 1002 for fixing the inductor assembly 102 and the transformer 103 .

[0070] In these embodiments, the inductor assembly 102 and transformer 103 can be secured together using potting compound 107. This effectively dissipates heat generated by the components through the potting compound 107's significantly higher thermal conductivity than air and the heat dissipation capabilities of the enclosure 100. Furthermore, the potting compound 107 also provides excellent insulation, effectively preventing interference between the inductor assembly 102 and transformer 103.

[0071] In some embodiments, optionally, the housing is a metal housing.

[0072] In some embodiments, optionally, the box body 100 is an aluminum box body 100 .

[0073] In some embodiments, optionally, the inductor box assembly 10 further includes: a heat dissipation assembly 108 , which is disposed outside the box body 100 and is used to dissipate heat generated by the inductor assembly 102 and the transformer 103 .

[0074] In these embodiments, a heat dissipation assembly 108 may be provided outside the box body 100 to dissipate heat, thereby further improving the overall heat dissipation effect of the inductor box assembly 10 .

[0075] In some embodiments, optionally, the heat dissipation assembly 108 includes: a plurality of first heat dissipation fins arranged at intervals along the height direction of the box body 100 ; and a plurality of second heat dissipation fins arranged at intervals along the width direction of the box body 100 .

[0076] In these embodiments, heat can be dissipated by a plurality of heat dissipation fins arranged at intervals, thereby improving the heat dissipation efficiency of the inductor box assembly 10 .

[0077] In some embodiments, optionally, as Figure 6As shown, a mounting opening 1008 is provided on the box body 100, and the mounting opening 1008 is communicated with the mounting cavity 1002. The inductor box assembly 10 also includes: a mounting groove 109, which is provided at the mounting opening 1008; and a sealing member 110, which is provided in the mounting groove 109 and is used to seal the connection between the inductor box assembly 10 and the energy storage inverter 20.

[0078] In these embodiments, a mounting groove 109 can be provided at the mounting opening 1008 of the box body 100, and then a seal 110 can be provided in the mounting groove 109. In this way, when the inductor box assembly 10 is installed, the connection between the inductor box assembly 10 and the energy storage inverter 20 can be sealed by the seal 110, thereby preventing dust from entering the interior of the energy storage inverter 20.

[0079] In some embodiments, optionally, the inductor box assembly 10 further includes: a plurality of mounting structures 111 disposed on the box body 100 , and the inductor box assembly 10 is fixedly mounted to the energy storage inverter 20 via the plurality of mounting structures 111 .

[0080] In some embodiments, optionally, the plurality of mounting structures 111 are arranged symmetrically to each other.

[0081] In some embodiments, optionally, a threaded hole 112 is provided on the box body 100 , which can be threadedly connected to the energy storage inverter 20 .

[0082] According to an embodiment of the first aspect of the present invention, the first aspect of the present invention proposes an inductor box assembly, including a box body, a potting compound, an inductor, a partition and a transformer. The box body is an aluminum heat dissipation box body, which is used to accommodate the potted inductor and transformer, and is used to connect to the inverter box body and fix the leads or terminals. The potting compound has thermal conductivity and insulation, and the potting compound is used to pot and fix the inductor or transformer. The inductor is used in the inverter or buck-boost circuit and needs to be potted in the box body due to severe heat generation. The transformer is used in the buck-boost circuit and needs to be potted in the box body due to severe heat generation. A partition is provided in the box body to divide the box body into a first cavity and a second cavity, and the cavity can be used to arrange the transformer and the inductor coil. The inner cavity of the box body is compatible with the placement of the inductor and the transformer, that is, the same inductor box body can be assembled with inductor box assemblies of different forms.

[0083] According to one embodiment of the first aspect of the present invention, an inductor box assembly for a household energy storage inverter is provided. The structural layout of the inductor box assembly for a household energy storage inverter is as follows: the entire inductor box assembly includes a box body, an inductor, a transformer, a lead terminal PCB (Printed Circuit Board), support columns, and potting compound. The box body of the household energy storage inverter is structured as follows: the inner portion of the box body is divided into two chambers: a transformer chamber and an inductor chamber. Sealing strip slots are provided around the outer perimeter of the screw holes on the box body for installing sealing strips.

[0084] In some embodiments, optionally, the outside of the box body uses fins for heat dissipation, and the fins are designed to be in a vertical direction when the energy storage inverter is in normal use.

[0085] In some embodiments, optionally, a threaded hole is provided on the box body, which can be threadedly connected to the product or PCB.

[0086] In some embodiments, optionally, a four-corner symmetrical hanging structure (installation structure) is provided on the outside of the box body, which can be placed and hung at any position.

[0087] In some embodiments, the transformer optionally utilizes lead-out terminals. The PCB for the lead-out terminals is welded to the transformer lead-out terminals. Support columns are used to secure the PCB to the upper portion of the box, with the transformer mostly submerged in potting compound. The support columns serve as terminal outlets because they accurately define the position of the inductor assembly's external terminals, facilitating hard connections. The inductor utilizes lead wires, which are placed within the inductor cavity and then potted.

[0088] In some embodiments, the bottom of the inverter housing optionally includes a rectangular hole (connector) for accommodating the PCB and lead wires, as well as a circular hole (connector) for securing the housing to the inductor assembly. These holes correspond to the threaded holes on the inductor assembly. During installation, first thread the inductor assembly through the bottom of the housing according to the corresponding holes on the PCB, and then thread the inductor leads through the rectangular hole, ensuring that the threaded holes on the housing align with the housing through-holes. Then, secure the assembly with screws.

[0089] The key points of this embodiment are:

[0090] 1. The inner part of the box is divided into two chambers, namely the transformer chamber and the inductor chamber.

[0091] 2. The inductor adopts the lead method and the inductor is encapsulated in the inductor cavity.

[0092] 3. The transformer adopts the lead-out terminal form. The PCB of the lead-out terminal is fixed to the inductor by welding. The whole body and the box body adopt support columns to fix the PCB to the upper part of the box body. Most of the transformer is sunk in the potting glue.

[0093] 4. The outside of the box uses fins for heat dissipation, and the fins are designed to be in the vertical direction when the inverter is in normal use.

[0094] 5. The transformer cavity is compatible with inductor placement, that is, the same inductor box body can be assembled with different forms of inductor box components.

[0095] 6. The inductor box is equipped with a sealing strip slot for installing the sealing strip.

[0096] 7. The inductance box is equipped with threaded holes, which can be threadedly connected to the product.

[0097] 8. The transformer is directly connected to the inverter's internal circuit board through the lead terminal, eliminating the need for leads and fixation.

[0098] 9. The outside of the inductor box is equipped with a four-corner symmetrical hanging structure, which can be placed and hung at will.

[0099] The beneficial effects of this application are as follows:

[0100] This application aims to solve the problem of messy wiring of the external inductor box of the energy storage inverter. It proposes a structure of inductor boxes with different cavities specially set up and placed separately, as well as an external terminal structure to avoid wiring. The terminals are directly connected to the PCB and placed in separate cavities. The AC and DC are placed separately and symmetrically to reduce lead wires, shorten the wire length, and make the assembly of the whole product more reasonable.

[0101] like Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, the second aspect of the present invention proposes an energy storage inverter 20, comprising: an inverter case 200; a first circuit board 201, arranged in the inverter case 200; an inductor box assembly 10 as in any embodiment of the first aspect, mounted on the inverter case 200 and electrically connected to the first circuit board 201.
