Description

Power module assembly

[0001] The present invention relates to a power module assembly.

[0002] Power module assemblies are used in power converters by integrating multiple power semiconductor devices and capacitors for power storage into a single module to enable efficient power conversion. Such power module assemblies can be applied, for example, in marine propulsion drives. The DC link capacitor used during DC-AC power conversion in the power module assembly plays a role in improving power quality by balancing the instantaneous power difference between the input power and the output load and reducing DC voltage ripple. Generally, electrolytic or film capacitors are used as DC link capacitors, and their use is directly linked to the lifespan and performance of the power module assembly.

[0003] Power module assemblies, including capacitors, play a critical role in eco-friendly marine drive systems. However, vibrations occurring in the marine environment can severely impact the reliability of power modules. In particular, loosening of connections between components can lead to changes in electrical resistance or thermal resistance coefficients, causing issues with system performance and stability. Therefore, to prevent these problems, it is crucial to design vibration-robust power modules that consider mechanical durability through environmental vibration testing. This ensures that power converters used on ships maintain high reliability and operate stably for extended periods.

[0004] Prior art for such power module assemblies includes EP Registration 3093860 B1 and EP Publication 4383421 A1.

[0005] The objective of the present invention is to provide a power module assembly capable of storing power and performing power conversion.

[0006] The objective of the present invention is to ensure that the components constituting the power module assembly are fixed in the correct position.

[0007] The objective of the present invention is to enable the smooth dissipation of heat generated internally during the use of a power module assembly to the outside.

[0008] The present invention for achieving the above-mentioned purpose may include a frame, a heat sink installed on one side surface of the frame, a power storage module mounted on the frame with one side in contact with the heat sink, a first fixing bracket coupled to one side of an assembly on which the power storage module is mounted on the frame to support the frame, a second fixing bracket coupled to the upper surface of an assembly on which the power module is mounted on the frame to support the frame, and a third fixing bracket coupled to the lower surface of an assembly on which the power module is mounted on the frame to support the frame.

[0009] The frame is used in an upright position with multiple power storage modules mounted on it, so that the power storage modules can be installed to protrude in one direction parallel to the ground.

[0010] It may further include a power module installed on one side of the above frame and acting as a switch.

[0011] It may further include a first busbar electrically connected to the electrode of the power storage module and also electrically connected to the power module, and a second busbar electrically connected to the power module.

[0012] A fixed support may be further provided, with one end connected to the frame and the other end connected to the first busbar to support the first busbar on the frame.

[0013] The first fixing bracket may include a first body having an opening formed therein, a first fastening piece formed in a predetermined area of ​​the first body and fastened to the frame side and having a plurality of first fastening holes, and a first fixing piece formed along one edge of the first body, fixed to the outside, and having a plurality of first fixing holes.

[0014] The second fixing bracket may include a second body having an opening formed therein, a second fastening piece formed in a predetermined area of ​​the second body and fastened to the frame side and having a plurality of second fastening holes, and a second fixing piece formed along both edges of the second body, fixed to the outside, and having a plurality of second fixing holes.

[0015] The third fixing bracket may include a third body having an opening formed therein, a third fastening piece formed in a predetermined area of ​​the third body and fastened to the frame side and having a plurality of third fastening holes, and a third fixing piece formed along one edge of the third body, fixed to the outside, and having a plurality of third fixing holes.

[0016] One of the third fixed pieces may be connected to the third body through an extension piece and extend in a direction orthogonal to the surface of the third body.

[0017] The power module assembly according to the present invention can have the following effects.

[0018] In the present invention, a plurality of capacitors, which are power storage modules, are mounted on a frame and operated. At this time, the frame on which the capacitors are mounted is fixed and supported by a first fixing bracket, a second fixing bracket, and a third fixing bracket. Additionally, the first busbar and the second busbar can also indirectly serve to fix the capacitors.

[0019] In this way, the first to third fixing brackets secure the frame on which the capacitor, which is a power storage module, is installed to the fixing part from three directions, thereby absorbing vibrations transmitted from the outside, and the first and second busbars are also connected to the outside to indirectly fix the position of the capacitor. Therefore, the capacitor, which is a power storage module, is made robust against external vibrations, thereby improving structural contact force.

[0020] Furthermore, in the present invention, a first hanging protrusion and a second hanging protrusion formed on the outer surface of a frame and a capacitor, which is a corresponding power storage module, are combined to allow the capacitor to be more firmly attached to the frame. In particular, the fixed support can firmly maintain the space between the frame and the first busbar, so that the capacitor installed on the frame can remain in its correct position, and in particular, the relative position between the heat sink and the capacitor can remain unchanged. Consequently, as the contact state between the heat sink and the capacitor is accurately maintained, the thermal resistance coefficient is reduced, allowing for smoother heat transfer from the capacitor to the heat sink, thereby enabling effects such as improved durability of the capacitor.

[0032] Hereinafter, some embodiments of the present invention will be described in detail with reference to exemplary drawings. It should be noted that in assigning reference numerals to the components of each drawing, the same components are given the same reference numeral whenever possible, even if they are shown in different drawings. Furthermore, in describing the embodiments of the present invention, if it is determined that a detailed description of related known components or functions would hinder understanding of the embodiments of the present invention, such detailed description is omitted.

[0033] In addition, terms such as first, second, A, B, (a), (b), etc., may be used when describing the components of the embodiments of the present invention. These terms are intended only to distinguish the components from other components, and the essence, order, or sequence of the components is not limited by the terms. Where it is stated that a component is "connected," "combined," or "connected" to another component, it should be understood that the component may be directly connected or connected to the other component, but that another component may also be "connected," "combined," or "connected" between each component.

[0034] The configuration of a preferred embodiment of a power module assembly according to the present invention is described. In this specification, a capacitor (20) that is a power storage module is used as an example of an embodiment of a power module assembly. However, instead of using a capacitor (20) that is a power storage module, a battery cell may be used. In the following description, the power storage module is described as a capacitor (20).

[0035] FIGS. 1 and FIGS. 2 show a configuration without an outer casing (not shown) of the power module assembly. A frame (10) forms the skeleton of the power module assembly. The frame (10) may be configured by separating it into multiple parts. In FIG. 3, the frame (10) is formed by separating it into three parts. However, the frame (10) may be formed as a single unit. The frame (10) has a predetermined thickness. The thickness (t) of the frame (10) is made to be 25% or greater than the height (H) of the capacitor (20) described below. However, it is preferable that the thickness of the frame (10) be less than half the height (H) of the capacitor (20). This is to prevent the capacitor (20) from being blocked from contacting air by the frame (10). That is, the thickness (t) of the frame (10) is set so that the capacitor (20) can come into relatively large contact with the air to facilitate heat dissipation to the outside, while also ensuring that the mounting state on the frame (10) is sturdy. The frame (10) can be made of an insulating material. Of course, it can also be made by using a metal material as a frame and surrounding the outer surface with an insulating material.

[0036] A plurality of through holes (12) may be formed through the frame (10). A plurality of through holes (12) may be formed in the frame (10) at regular intervals. In the illustrated embodiment, 12 through holes (12) are formed in one frame (10). A first hook protrusion (14), as seen in FIG. 11, may be formed on the inner surface of the through hole (12). The first hook protrusion (14) formed on the inner surface of the through hole (12) is formed concavely in a channel shape. The first hook protrusion (14) may be formed around the entire inner surface of the through hole (12).

[0037] For reference, the first hanging protrusion (14) may be formed protruding from the inner surface of the through hole (12). That is, the first hanging protrusion (14) may be formed in the shape of a protruding rib rather than a channel shape.

[0038] A heat sink (16) may be combined with the above-mentioned frame (10). The heat sink (16) may be in the shape of a plate having an area corresponding to one side surface of the entire frame (10). The heat sink (16) is made of a material with good heat transfer properties. The heat sink (16) may have a cooling channel (not shown) through which cooling water flows. Accordingly, an inlet section for delivering cooling water to the cooling channel and an outlet section from which cooling water exits the cooling channel may be provided on one side of the heat sink (16). As cooling water flows along the cooling channel, heat transferred to the heat sink (16) can be transferred to the cooling water.

[0039] The surface of the heat sink (16) faces the inside of the through hole (12). One outer surface of the capacitor (20), which will be described below, is installed in close contact with the surface of the heat sink (16). Instead of the capacitor (20) being in close contact with the surface of the heat sink (16), a material with good heat transfer properties may be placed between the surface of the heat sink (16) and the capacitor (20). For example, a material such as heat transfer grease with good heat transfer properties may be placed between the surface of the heat sink (16) and the capacitor (20).

[0040] A first fixing bracket (17), a second fixing bracket (18), and a third fixing bracket (19) may be mounted on the frame (10). The fixing brackets (17, 18, 19) may be made of metal. Of course, the inside may be metal and the outside may be made of insulating synthetic resin. These fixing brackets (17, 18, 19) may be mounted on the frame (10) or simultaneously mounted on the frame (10) and the heat sink (16). Of course, the fixing brackets (17, 18, 19) may also be mounted on the heat sink (16). Furthermore, these fixing brackets (17, 18, 19) may be mounted on the frame (10) or the heat sink (16) and simultaneously connected to the outside or the enclosure. These fixed brackets (17, 18, 19) are made of a rigid material and can firmly fix the frame (10) and the heat sink (16).

[0041] As can be seen in FIG. 5, the first fixing bracket (17) has a frame formed by the first body (171). The first body (171) can be made of, for example, a metal material. An opening (173) is formed in the first fixing bracket (17). Through the opening (173), the capacitor (20), which will be described below, can be seen. Of course, air can flow through the opening (173).

[0042] The first fixing bracket (17) is intended for fastening the frame (10) side to the outside or the outer casing. To this end, a first fastening piece (175) is formed along one edge of the first fixing bracket (17). The first fastening piece (175) refers to a part of the first body (171). That is, the first fastening piece (175) is not clearly distinguishable from the first body (171) in appearance.

[0043] A plurality of first fastening holes (175') may be formed in a row on the first fastening piece (175). The first fastening holes (175') do not necessarily have to be arranged in a row. Within a feasible range, the first fastening holes (175') may be arranged in a zigzag pattern. The first fastening piece (175) is intended for fastening with the frame (10). A fastening member passes through the first fastening holes (175') to perform the fastening. The fastening member may be a screw or a bolt.

[0044] A first fixing piece (177) for fixing to the outside or an outer casing is formed on the first fixing bracket (17). The first fixing piece (177) extends in a direction orthogonal to the first fastening piece (175). That is, the first fixing piece (177) can be formed orthogonally to one side of the first body (171). A plurality of first fixing holes (177') are formed in the first fixing piece (177). A fastening member passes through the first fixing holes (177') to perform fastening. The first fixing holes (177') are formed in a line, but they may also be formed in a zigzag pattern. Screws or bolts may be used as the fastening member.

[0045] As can be seen in FIG. 6, the second fixing bracket (18) has a frame formed by the second body (181). The second body (181) can be made of, for example, a metal material. An opening (183) is formed in the second fixing bracket (18). Through the opening (183), the capacitor (20), which will be described below, can be seen. Of course, air can flow through the opening (183).

[0046] The second fixing bracket (18) is intended for fastening the frame (10) side to the outside or the outer casing. To this end, a second fastening piece (185) is formed along one edge of the second fixing bracket (18). The second fastening piece (185) refers to a part of the second body (181). That is, the second fastening piece (185) is not clearly distinguishable from the second body (181) in appearance. A plurality of second fastening holes (185') may be formed in a row on the second fastening piece (185). The second fastening holes (185') do not necessarily have to be arranged in a row. Within a possible range, the second fastening holes (185') may be arranged in a zigzag pattern. The second fastening piece (185) is intended for fastening to the frame (10) side. A fastening member passes through the second fastening hole (185') to perform fastening. The fastening member may be a screw or a bolt.

[0047] A second fixing piece (187) for fixing to the outside or an outer casing is formed in the second fixing bracket (18). The second fixing piece (187) extends in a direction orthogonal to the second fastening piece (185). That is, the second fixing piece (187) can be formed orthogonally to one side of the second body (181). A plurality of second fixing holes (187') are formed in the second fixing piece (187). A fastening member passes through the second fixing holes (187') to perform fastening. The second fixing holes (187') are formed in a line, but they may also be formed in a zigzag pattern. Screws or bolts may be used as the fastening member. In the second fixing bracket (18), the second fixing piece (187) extends parallel to each other along the edges of both sides of the second body (181).

[0048] As can be seen in FIG. 7, the third fixing bracket (19) has a frame formed by the third body (191). The third body (191) can be made of, for example, a metal material. An opening (193) is formed in the third fixing bracket (19). Through the opening (193), the capacitor (20), which will be described below, can be seen. Of course, air can flow through the opening (193).

[0049] The third fixing bracket (19) is intended for fastening the frame (10) side to the outside or the outer casing. To this end, a third fastening piece (195) is formed along one edge of the third fixing bracket (19). The third fastening piece (195) refers to a part of the third body (191). That is, the third fastening piece (195) is not clearly distinguishable from the third body (191) in appearance. A plurality of third fastening holes (195') may be formed in a row on the third fastening piece (195). The third fastening holes (195') do not necessarily have to be arranged in a row. Within a possible range, the third fastening holes (135') may be arranged in a zigzag pattern. The third fastening piece (195) is intended for fastening to the frame (10) side. A fastening member passes through the third fastening hole (195') to perform fastening. The fastening member may be a screw or a bolt.

[0050] A third fixing piece (197) for fixing to the outside or an outer casing is formed in the third fixing bracket (19). The third fixing piece (197) extends in a direction orthogonal to the third fastening piece (195). That is, it can be formed orthogonally to one side of the third body (191). A plurality of third fixing holes (197') are formed in the third fixing piece (197). The third fixing holes (197') are formed in a line, but they may not necessarily be formed in a zigzag pattern. A fastening member passes through the third fixing holes (197') to perform fastening. The fastening member may be a screw or a bolt. In the third fixing bracket (19), the third fixing piece (197) extends parallel to each other along the edges of both sides of the third body (191).

[0051] One of the third fixing pieces (197) may be connected to the third body (191) by an extension piece (199). As clearly illustrated in FIG. 7, the extension piece (199) has an L-shaped cross section. In this way, by bending the extension piece (199) once, one third fixing piece (197) connected to the extension piece (199) may be extended in a direction perpendicular to the third body (191).

[0052] The capacitor (20) is cylindrical in shape. As explained above, the capacitor (20) may be a battery cell. The capacitor (20) may be an electrolytic capacitor. The capacitor (20) serves to store voltage and provide the stored voltage for use. The configuration of the capacitor (20) is clearly illustrated in FIG. 10. The capacitor body (22) forms the exterior and framework of the capacitor (20). The capacitor body (22) is cylindrical in shape. The components constituting the capacitor are contained within the capacitor body (22). An electrode (24) may be present on one outer surface of the capacitor body (22). The electrode (24) is a positive electrode and a negative electrode.

[0053] A second hanging protrusion (26) may be formed on the outer surface of the capacitor body (22). The second hanging protrusion (26) may be formed integrally with the capacitor body (22). The second hanging protrusion (26) may be formed around the outer surface of the capacitor body (22). The second hanging protrusion (26) has a protruding rib shape. The second hanging protrusion (26) protrudes from the outer surface of the capacitor body (22). The second hanging protrusion (26) is a part that is hooked onto the first hanging protrusion (14) of the frame (10). In the illustrated embodiment, the second hanging protrusion (26) has a protruding shape. The second hanging protrusion (26) may be made to correspond to the shape of the first hanging protrusion (14). That is, in the illustrated embodiment, since the first hanging protrusion (14) is channel-shaped, the second hanging protrusion (26) is protruding rib-shaped. However, if the first hanging protrusion (14) is protruding rib-shaped, the second hanging protrusion (26) can be channel-shaped.

[0054] Here, when the second hanging protrusion (26) becomes a rib shape, the degree of protrusion and when the first hanging protrusion (14) becomes a channel shape, the degree of indentation are extremely small values ​​when compared to the height (H) of the capacitor (20). That is, when a worker pushes the capacitor (20) into the through hole (12) of the frame (10), it is to the extent that it can be pushed in by force without using a separate tool.

[0055] The first hanging protrusion (14) and the second hanging protrusion (26) can each be formed at corresponding positions. Also, the first hanging protrusion (14) and the second hanging protrusion (26) are both formed in a circular shape. That is, they are formed around the inner surface of the through hole (12) 360 degrees and also around the outer surface of the capacitor body (22) 360 degrees. However, at least one of the first hanging protrusion (14) and the second hanging protrusion (26) may be formed intermittently. For reference, it is not desirable for the first hanging protrusion (14) and the second hanging protrusion (26) to be formed intermittently at the same time. This is because it reduces insertion workability. However, the hanging protrusion in the form of a channel may be formed over the entire area, and the hanging protrusion protruding in the form of a rib may be formed intermittently in some areas.

[0056] The power module assembly of the embodiment of the present invention is installed in an upright position as shown in FIG. 1 or FIG. 2. Accordingly, the height direction of the capacitor (20) can be extended in the horizontal direction. Accordingly, the electrode (24) portion of the capacitor (20) can become the free end of a kind of cantilever. In such a structure, if the power module assembly is used for a long time, the electrode portion of the capacitor (20) may sag relatively, causing the contact distance between the heat sink (16) and the capacitor (20) to be separated even slightly. If this happens, the heat transfer performance from the capacitor (20) to the heat sink (16) decreases.

[0057] In the present invention, a fixed support (30) is provided to connect the frame (10) and the first busbar (50), which will be described below, in order to prevent the free end of the capacitor (20) from sagging in the direction of gravity. The fixed support (30) may be made of plastic having a certain degree of rigidity. Of course, there may be a metal material forming a frame inside, and the outer surface may be surrounded by an insulating material.

[0058] A number of fixed supports (30) may be used. The fixed supports (30) are in the shape of a bar or rod and support the frame (10) and the first busbar (50) by connecting them. The fixed supports (30) pass between the capacitors (20) to connect the frame (10) and the first busbar (50). The first busbar (50) is connected to the electrode (24) of the capacitor (20), so when the fixed supports (30) are connected to the first busbar (50), they can serve to support the free end of the capacitor (20). The fixed supports (30) can be fastened to the frame (10) and the first busbar (50) in the form of screws.

[0059] A power module (40) may be mounted on the frame (10). The power module (40) may be installed on one side of the frame (10) where the heat sink (16) is mounted. The power module (40) converts direct current and alternating current and simultaneously acts as a switch to control the storage and supply of power.

[0060] There is a first busbar (50) electrically connected to the capacitor (20). Multiple first busbars (50) are provided to perform electrical connection between the capacitors (20) and the power module (40). The first busbar (50) is coupled to the electrode (24) of the capacitor (20) to be electrically connected.

[0061] The first busbar (50) can cover the outer surface (front side in Fig. 3), side, and rear of the assembly of the frame (10), capacitor (20), and heat sink (16). That is, a plurality of first busbars (50) are positioned around the assembly of the frame (10) and capacitor (20). For electrical connection between the first busbar (50) and the outside, there is a first connecting busbar (52). The first connecting busbar (52) can be connected to the outside through the outer side of the second fixing bracket (18).

[0062] The second busbar (60) electrically connects the power module (40) to the outside. Three second busbars (60) are stacked and installed facing the power module (40) on the back of the heat sink (16). A second connecting busbar (62) is used to connect the second busbar (60) to the outside. The second connecting busbar (62) can be connected to the outside from the side opposite where the first fixing bracket (17) is installed.

[0063] Here, the outer surface of the first busbar (50), second busbar (60), first connecting busbar (52), and second connecting busbar (62) is covered with an insulating material. Therefore, even if multiple busbars (50)(60)(52)(62) are used in an overlapping manner, there is no problem with insulation.

[0064] The use of a power module assembly according to the present invention having the configuration described above will be explained in detail below.

[0065] In the present invention, the frame (10) on which the capacitor (20) is installed can be firmly fixed within the power module assembly. This is because a plurality of components constituting the power module assembly are structurally and firmly connected to each other.

[0066] First, based on FIG. 1, the fixing support (30) and the first busbar (50) are structurally connected on one side based on the frame (10), the heat sink (16), and the power module (40) in the front-rear direction of the power module assembly, so that the capacitor (20) can be firmly fixed in the front-rear direction of the power module assembly.

[0067] Next, based on the frame (10) and the heat sink (16), a first fixing bracket (17) is mounted on one side and a first busbar (50) is mounted on the other side. Here, the first fixing bracket (17) is combined with the frame (10) and the heat sink (16) and is simultaneously fixed to the outside or the outer casing. Therefore, the side of the first fixing bracket (17) can be firmly fixed. And, on the opposite side, the first busbar (50) and the second connecting busbar (62) are fixed to the outside or the outer casing. Therefore, the movement of the frame (10) and the heat sink (16) in the left and right directions based on FIG. 1 can be restricted.

[0068] Meanwhile, the fixation in the vertical direction based on the above-mentioned frame (10) and heat sink (16) is examined. The upper direction of the above-mentioned frame (10) and heat sink (16) is fixed to the outside by the second fixing bracket (18). In addition, the lower direction of the above-mentioned frame (10) and heat sink (16) is fixed to the outside by the third fixing bracket (19). Due to the characteristics of this configuration, vertical movement on the side of the frame (10) where the capacitor (20) is installed hardly occurs. Therefore, the movement of the frame (10) and heat sink (16) in the vertical direction based on FIG. 1 can be restricted.

[0069] Furthermore, while the capacitor (20) is mounted on the frame (10), it is fixed between the first busbar (50) and the frame (10) by the fixing support (30). Thus, vibration of the frame (10) can be minimized. In addition, since the capacitor (20) is firmly fixed by the fixing between the first busbar (50) and the frame (10) by the fixing support (30), the connection between the capacitor (20) and the heat sink (16) can be maintained firmly. Therefore, heat dissipation from the capacitor (20) can be carried out smoothly.

[0070] In addition, in the present invention, the connection between the capacitor (20) and the frame (10) can be firmly formed by the mutual connection between the first hanging protrusion (14) and the second hanging protrusion (26). Accordingly, as the connection state between the frame (10) and the capacitor (20) becomes firm, the connection state between the capacitor (20) and the heat sink (16) can also be firmly maintained.

[0071] Although all components constituting an embodiment according to the present invention have been described as being combined or operating in combination, the present invention is not necessarily limited to such embodiments. That is, within the scope of the purpose of the present invention, all components may be selectively combined in one or more ways. Furthermore, terms such as "include," "constitute," or "have" described above, unless specifically stated otherwise, mean that the relevant component may be inherent; thus, they should be interpreted as allowing for the inclusion of additional components rather than excluding other components. All terms, including technical or scientific terms, have the same meaning as generally understood by those skilled in the art to which the present invention pertains, unless otherwise defined. Terms commonly used, such as those defined in advance, should be interpreted in accordance with their meaning in the context of the relevant technology and, unless explicitly defined in the present invention, should not be interpreted in an ideal or overly formal sense.
