Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and more particularly to a mounting base and electronic equipment. Background Technology

[0002] Photovoltaic inverters are a key component of solar photovoltaic systems. Their main function is to convert the direct current (DC) generated by photovoltaic modules into alternating current (AC) for use in homes, commercial facilities, or the power grid. The power devices in a photovoltaic inverter generate significant heat during operation, affecting its operational stability. These power devices include IGBTs, diodes, and MOSFETs. Heat sinks are typically used to dissipate heat from these devices. One of the key technical challenges in photovoltaic inverters is how to reliably and stably mount the power devices on the heat sinks and achieve effective heat transfer between them.

[0032] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0033] In the description of this application, it should be noted that, unless otherwise expressly 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 between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0034] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the accompanying drawings, and are only for the convenience of describing 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, and therefore should not be construed as a limitation of this application.

[0035] The terms "first," "second," and "third" (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular 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, for example, in orders other than those illustrated or described herein.

[0036] 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 display 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 display.

[0037] In related technologies, a photovoltaic (PV) inverter includes a heat sink, a control circuit board, a mounting base, and power devices. The power devices are electrically connected to the control circuit board and participate in the PV inverter's process of converting solar energy into alternating current. The heat sink is used to dissipate heat from the power devices. Power devices can include IGBTs, diodes, MOSFETs, or power modules, etc. To dissipate heat from the power devices, heat sinks are typically used. How to stably and reliably mount the power devices on the heat sink and achieve effective heat transfer between them is one of the technical problems that PV inverters need to solve.

[0038] To facilitate heat dissipation through thermally conductive contact between the power device and the heat sink, this application provides a mounting base and an electronic device. The mounting base provides elasticity via an elastic element located between a first fixing element and a second fixing element. This allows the first and second fixing elements to enclose the elastic element, preventing insulation breakdown of the mounting base. Furthermore, the mounting base has an abutment portion with a flat abutment surface on the side facing the first electronic device, enabling surface contact between the mounting base and the first electronic device. This results in more uniform force distribution on the first electronic device, leading to better thermal conductive contact between the first electronic device and the heat sink. The first electronic device includes a power device. It should be noted that thermal conductive contact includes indirect contact via other thermally conductive elements, such as ceramic gaskets or thermally conductive silicone, as well as direct contact between the first electronic device and the heat sink.

[0039] The following describes in detail the implementation of the mounting base and electronic device provided in this embodiment with reference to the accompanying drawings.

[0040] Reference Figures 1 to 3 As shown, the electronic device provided in this application embodiment includes a first electronic device 20, a heat sink 30 and a mounting base 10. The mounting base 10 is connected to the heat sink 30 and is used to make the first electronic device 20 and the heat sink 30 make thermal contact.

[0041] It should be noted that the electronic device may also include a second electronic device 40. The mounting base 10 can connect the first electronic device 20 and the second electronic device 40, and the first electronic device 20 is electrically connected to the second electronic device 40. The mounting base 10 can press the first electronic device 20 onto the heat sink 30, thereby improving the thermal conductivity between the heat sink 30 and the first electronic device 20, and thus improving the heat dissipation effect of the first electronic device 20.

[0042] For example, the first electronic device 20 may include one or more of an IGBT module, a diode, and a MOSFET, and the second electronic device 40 may be a circuit board.

[0043] Reference Figures 3 to 6 As shown, based on the above embodiments, this application also provides a fixing base 10, which includes a first fixing member 100, an elastic member 200 and a second fixing member 300. The elastic member 200 is located between the first fixing member 100 and the second fixing member 300, and the first fixing member 100 is connected to the second fixing member 300.

[0044] The second fastener 300 has at least one abutting portion 310 on the side opposite to the first fastener 100. The abutting portion 310 has an abutting plane 311 on the side opposite to the first fastener 100. The elastic member 200 is used to provide elastic force to the second fastener 300 so that the abutting plane 311 can make sufficient thermal contact with the first electronic device 20.

[0045] In this embodiment, the elastic element 200 is used to provide elastic force to the fixing seat 10, so that the first electronic device 20 can be directly or indirectly attached to the heat sink 30 under the elastic force of the fixing seat 10, thereby improving the degree of contact between the first electronic device 20 and the heat sink 30 and ensuring the heat dissipation effect.

[0046] Before the first fixing member 100 and the second fixing member 300 are connected, the elastic member 200 can be conveniently placed on the first fixing member 100 and the second fixing member 300, thereby facilitating the assembly of the first fixing member 100, the elastic member 200 and the second fixing member 300 together. After the first fixing member 100 and the second fixing member 300 are connected, they can be used to jointly wrap the elastic member 200, thereby preventing the elastic member 200 from being exposed, thereby improving the insulation performance of the elastic member 200 and improving the electrical strength of the fixing base 10, thereby preventing the fixing base 10 from causing insulation breakdown, and thus effectively preventing the fixing base 10 from causing electronic equipment failure.

[0047] The first fixing member 100 and the second fixing member 300 can be made of plastic, and the elastic member 200 can be made of metal.

[0048] To improve the heat dissipation effect of the first electronic device 20, an abutment portion 310 can be provided on the side of the second fixing member 300 facing the first electronic device 20. The abutment portion 310 has an abutment plane 311, which can make surface contact with the first electronic device 20. In this way, the abutment plane 311 increases the contact area between the second fixing member 300 and the first electronic device 20, and the abutment plane 311 can evenly apply the elastic force of the elastic member 200 to the first electronic device 20, thereby making the first electronic device 20 fit more closely with the heat sink 30, thus improving the heat dissipation effect of the first electronic device 20.

[0049] In specific implementation, multiple abutting parts 310 can be provided, and each abutting part 310 can have an abutting plane 311. In this way, multiple abutting planes 311 are in contact with the first electronic device 20, thereby effectively increasing the contact area between the fixing base 10 and the first electronic device 20.

[0050] In related technologies, the mounting base uses a metal elastic steel sheet, which is connected to the heat sink by bolts. Insulating paper is provided between the metal elastic steel sheet and the IBGT single-tube module to insulate and isolate them. Because the contact between the metal elastic steel sheet and the IBGT single-tube module is line contact, this can lead to uneven stress on the IBGT single-tube module. Furthermore, in humid environments, the insulating paper is prone to insulation breakdown, potentially causing a short circuit. In this embodiment, however, the mounting base 10 and the first electronic device 20 have surface contact. That is, the mounting base 10 can contact the first electronic device 20 through at least one abutment surface 311, thereby increasing the contact area between the mounting base 10 and the first electronic device 20. This allows the elastic force of the elastic element 200 to be applied evenly to the first electronic device 20, resulting in good thermal conductivity contact between the first electronic device 20 and the heat sink 30.

[0051] It should be understood that since the first electronic device 20 is a high-voltage energized device and the heat sink 30 is a metal structural component, a thermally conductive insulating pad can be added between them to simultaneously meet the requirements for thermal conductivity and insulation level. For example, a ceramic pad can be used, allowing for thermally conductive contact between the two devices while also meeting the insulation requirements between the first electronic device 20 and the heat sink 30. In this way, the mounting base 10 can press the first electronic device 20 firmly onto the insulating pad, and further press the first electronic device 20 and the insulating pad together onto the heat sink 30, thereby improving the heat dissipation and insulation performance of the first electronic device 20. Furthermore, thermally conductive silicone grease can be applied between any two contact surfaces of the first electronic device, the insulating pad, and the heat sink to further increase thermal adhesion and improve the heat dissipation capacity of the first electronic device.

[0052] The mounting base 10 provided in this embodiment includes a first fixing member 100, an elastic member 200, and a second fixing member 300. The second fixing member 300 includes an abutment portion 310, and the abutment portion 310 includes an abutment plane 311. By providing elasticity to the mounting base 10 with elastic force, and by using the first fixing member 100 and the second fixing member 300 to jointly mount the elastic member 200, the elastic member 200 is enclosed within the mounting base 10, thereby improving the insulation performance of the elastic member 200. By providing the abutment plane 311 for contact with the first electronic device 20, the contact area between the second fixing member 300 and the first electronic device 20 is increased, thereby allowing the elasticity of the mounting base 10 to be evenly applied to the first electronic device 20. This improves the heat dissipation effect of the first electronic device 20 by increasing the fit between the first electronic device 20 and the heat sink 30. Therefore, the mounting base 10 provided in this embodiment has better insulation performance and improves the heat dissipation effect of the first electronic device 20.

[0053] Reference Figures 4 to 6 As shown, in one possible implementation, the first fastener 100 has at least two first snap-fit ​​portions 110, which are located on both sides of the first fastener 100 along a first direction, and the second fastener 300 has at least two second snap-fit ​​portions 320, with the first snap-fit ​​portions 110 and the second snap-fit ​​portions 320 snapping into each other in a one-to-one manner.

[0054] Thus, by providing a first snap-fit ​​portion 110 on the first fastener 100 and a second snap-fit ​​portion 320 on the second fastener 300, the first fastener 110 and the second snap-fit ​​portion 320 can be snapped together, thereby achieving the connection between the first fastener 100 and the second fastener 300. Furthermore, the connection between the first fastener 100 and the second fastener 300 is relatively simple and convenient.

[0055] For example, two first snap-fit ​​portions 110 can be provided on one side of the first fastener 100 along the first direction, and the two first snap-fit ​​portions 110 are spaced apart along the second direction. Two first snap-fit ​​portions 110 can also be provided on the other side of the first fastener 100 along the first direction, and the two first snap-fit ​​portions 110 are spaced apart along the second direction. Correspondingly, four second snap-fit ​​portions 320 can be provided on the second fastener 300, and each first snap-fit ​​portion 110 and each second snap-fit ​​portion 320 are snapped together one by one. In this way, the connection reliability between the first fastener 100 and the second fastener 300 can be improved.

[0056] The first direction can be referenced. Figure 2 , Figure 5 , Figure 7 The X direction is shown in the figure, and the second direction can be referenced. Figure 2 , Figure 5, Figure 7 in the Y direction.

[0057] Reference Figure 3 , Figure 5 and Figure 7 As shown, in some embodiments, the first fixing member 100 has a first connecting portion 120, the first connecting portion 120 has a clearance hole 121, the elastic member 200 has a first connecting hole 210, and the second fixing member 300 has a second connecting hole 330. The clearance hole 121, the first connecting hole 210 and the second connecting hole 330 are connected in sequence and are used to pass through a threaded connector. The threaded connector is used to connect the fixing base 10 and the radiator 30.

[0058] It is understandable that after the first fixing member 100, the elastic member 200 and the second fixing member 300 are assembled together, the fixing base 10 and the heat sink 30 can be connected by a threaded connector, thereby pressing the first electronic device 20 between the fixing base 10 and the heat sink 30, or pressing the first electronic device 20 between the fixing base 10 and the insulating gasket.

[0059] Specifically, the first fixing member 100 has a first connecting portion 120, the first connecting portion 120 has a clearance hole 121 for threaded connectors to pass through, the elastic member 200 has a first connecting hole 210 for threaded connectors to pass through, and the second fixing member 300 has a second connecting hole 330 for threaded connectors to pass through. In this way, the threaded connector can pass through the clearance hole 121, the first connecting hole 210 and the second connecting hole 330 in sequence. The head of the threaded connector can be stopped on the side of the elastic member 200 facing the first fixing member 100. The threaded connector can be threadedly connected to the radiator 30. Since the first fixing member 100 and the second fixing member 300 are connected to each other, the fixing seat 10 can be connected to the radiator 30.

[0060] Continue to refer to Figure 3 , Figure 5 and Figure 7 As shown, in one possible implementation, the second fastener 300 further has at least two first limiting portions 340, which are located on both sides of the second fastener 300 along the first direction, and the first limiting portions 340 are located on the side of the second fastener 300 opposite to the first fastener 100.

[0061] In this way, since the first limiting part 340 is disposed toward the first electronic device 20 and the first limiting part 340 is located on both sides of the second fixing member 300 along the first direction, the first limiting part 340 can limit the position of the first electronic device 20 along the first direction, thereby preventing the relative position between the first electronic device 20 and the fixing base 10 from shifting.

[0062] Reference Figures 3 to 5 As shown, in some embodiments, there are at least two abutting portions 310, which are spaced apart along a first direction, and are respectively used to abut against at least two first electronic devices 20.

[0063] In this way, when the electronic device is equipped with multiple first electronic devices 20, the fixing base 10 and each first electronic device 20 can make surface contact through the abutting plane 311, so that the elastic force of the fixing base 10 can be evenly applied to each first electronic device 20, thereby making each first electronic device 20 fit tightly with the heat sink 30.

[0064] For example, each abutting part 310 may abut one-to-one with each first electronic device 20, or two abutting parts 310 may abut one first electronic device 20.

[0065] Reference Figure 4 , Figure 5 As shown, in one possible implementation, the second fastener 300 further has at least one second limiting portion 350, which is located between two adjacent abutting portions 310 and protrudes from the abutting portions 310.

[0066] Thus, when the fixing seat 10 needs to press the two first electronic devices 20 onto the heat sink 30, the two first electronic devices 20 are arranged along the first direction. A first limiting part 340 and a second limiting part 350 cooperate to restrict the position of one first electronic device 20 along the first direction. Another first limiting part 340 and a second limiting part 350 cooperate to restrict the position of the two first electronic devices 20 along the first direction, thereby preventing the first electronic devices 20 from being too close together.

[0067] Reference Figure 4 and Figure 7 As shown, in some embodiments, the first fixing member 100 further includes at least one support portion 130, the at least one support portion 130 being located on the side of the first fixing member 100 opposite to the second fixing member 300, the first connecting portion 120 protruding from the support portion 130, and the support portion 130 being used to abut against the second electronic device 40.

[0068] In other words, the body of the first electronic device 20 and the second electronic device 40 can be located on both sides of the body of the fixing base 10. The pins of the first electronic device 20 can be bent toward the second electronic device 40, thereby making the pins electrically connected to the second electronic device 40. A support part 130 can be provided on the side of the fixing base 10 facing the second electronic device 40. In this way, after the fixing base 10 is connected to the second electronic device 40, the support part 130 can abut against the second electronic device 40, thereby making the fixing base 10 and the second electronic device 40 stable.

[0069] In one possible implementation, the support portion 130 and the first connecting portion 120 are located on both sides of the first fixing member 100 along the second direction.

[0070] Thus, the support portion 130 and the first connecting portion 120 can respectively support the two sides of the second electronic device 40 along the second direction. Since the first connecting portion 120 is located on the side of the first fixing member 100 along the second direction, the diameter of the clearance hole 121, the first connecting hole 210 and the second connecting hole 330 can be enlarged, so as to use a threaded connector with a larger diameter to connect the fixing base 10 and the heat sink 30, thereby increasing the preload between the fixing base 10 and the heat sink 30, so that the first electronic device 20 is subjected to uniform force, the first electronic device 20 and the heat sink 30 have a higher degree of fit, and this arrangement does not increase the size of the fixing base 10 along the second direction.

[0071] Reference Figure 7 As shown, in some embodiments, the first connecting portion 120 also has a latch 122, which is located outside the clearance hole 121 and is used to engage with the second electronic device 40.

[0072] It should be understood that the second electronic device 40 can be provided with a locking hole, and the buckle 122 can be engaged with the locking hole. In this way, when connecting the fixing base 10 and the second electronic device 40, the buckle 122 can be locked into the locking hole first, and then the support part 130 can be pressed against the side of the second electronic device 40 facing the heat sink 30, thereby making the fixing base 10 and the second electronic device 40 stably connected.

[0073] Reference Figure 3 As shown, in one possible implementation, the elastic member 200 includes a second connecting portion 220 and two elastic portions 230, a first connecting hole 210 is located in the second connecting portion 220, and the two elastic portions 230 are connected to both sides of the second connecting portion 220 along a first direction.

[0074] Understandably, when the mounting base 10 is connected to the heat sink 30 via the threaded connector, the second connection part 220 can be fixed. Since the elastic part 230 is sandwiched between the first fixing member 100 and the second fixing member 300, the elastic part 230 has elastic potential energy, which can provide elastic force to the first fixing member 100 and the second fixing member 300, thereby enabling the mounting base 10 to provide elastic force to the first electronic device 20.

[0075] In a specific implementation, there can be two elastic parts 230, which are spaced apart along the first direction. This allows the elastic force of the elastic member 200 to be applied evenly to the first fixing member 100 and the second fixing member 300, thereby allowing the elastic force of the fixing seat 10 to be applied evenly to the first electronic device 20.

[0076] When the electronic device has two first electronic components 20, the two elastic parts 230 can apply elastic force to the two first electronic components 20 through the two abutting parts 310 of the second fixing member 300, so that the two first electronic components 20 can make good thermal contact with the heat sink 30, thereby improving the heat dissipation performance of the two first electronic components 20.

[0077] Finally, it should be noted that the above 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 or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
