Description

[Technical Field]

[0001] The present invention relates to electrical components. [Background technology]

[0002] Conventionally, there are cases where the following configuration is used to cool heat-generating electric elements such as capacitors and reactors. The heat-generating electric elements are molded with resin to form a resin molded product (hereinafter referred to as a molded product). A part of the molded product comes into contact with the cooling liquid, and a connecting portion between the components is provided at the contact point with the cooling liquid. A sealing member is provided at the connecting portion to prevent leakage of the cooling liquid. For example, Patent Document 1 discloses the configuration shown in Figure 8 below. Figure 8 shows an enlarged cross-sectional view of a conventional cooling structure for an electric component.

[0003] Since electrical elements 101s such as capacitors and reactors generate heat during operation, the molded electrical component body 101 is cooled by contacting it with cooling liquid 109 flowing through cooling liquid flow paths 102s formed in the housing 102 and exchanging heat with it. A cylindrical vibration-isolating rubber 103r is fixed to the center of the columnar vibration-isolating member 103 disposed between the electrical component body 101 and the housing 102. The vibration-isolating rubber 103r damps the vibration of the housing 102.

[0004] The electrical component body 101 having a sealed structure is fixed to the housing 102 by inserting a bolt 104 through the electrical component body 101 and the vibration-proof member 103 and screwing it into the housing 102 . A seal member 105 having a double seal 105a, 105b structure (a substantially H-shaped cross section) that suppresses leakage of cooling liquid 109 is disposed between housing 102 and electrical component body 101. Seal member buckling prevention walls 102a, 102b are formed on both sides of housing 102, sandwiching seal member 105 to prevent it from falling over. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 6046812 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the prior art in Patent Document 1 assumes a flange-connected pipe structure, which means that it does not take into consideration issues that may arise when cooling by bringing the cooling liquid in the cooling liquid flow path 102s directly into contact with the electric component body 101, such as the molding of the cooling liquid flow path 102s in the housing 102 in which the electric component body 101 is mounted, the vibration damping effect against vibration of the housing 102, or the cooling liquid flow pressure acting on the electric component body 101.

[0007] As shown in FIG. 8, when the waterproof sealing member 105 and the vibration isolating member 103 are simply arranged side by side, the dimension from the cooling liquid flow path 102s to the fixing part with the bolt 104 is long. For example, the waterproof function requires a length s1 of the seal member buckling prevention wall 102a, a length s2 of the seal member buckling prevention wall 102b, and a groove width s3 for the seal member 105.

[0008] The vibration-proofing function requires assembly dimension s4 of seal member 105. Because clearance is required between seal member buckling prevention wall 102b and vibration-proofing member 103, a total dimension of s1+s2+s3+s5 is required for waterproofing and vibration-proofing functions. Furthermore, since the sealing member 105, which is a waterproof component, and the vibration-proofing member 103, which is a vibration-proof component, are separate components, there is a problem that assembling them into the housing 102 requires a lot of labor and there is a large variation in the dimensions when assembled.

[0009] The present invention has been made in view of the above circumstances, and has as its object to provide an electrical component that can suppress leakage of cooling liquid and also achieve vibration isolation. [Means for solving the problem]

[0010] In order to solve the above-mentioned problems, the electrical component of the present invention includes an electrical component body that accommodates an electrical element, at least a portion of the bottom surface of which is flat and has a first through hole for fixing provided within the flat portion, a plate that is provided with a second through hole that is arranged opposite the first through hole and a cooling hole through which a cooling liquid flows, vibration-damping rubber that is arranged on one side and the other side of the plate in a state that surrounds the second through hole of the plate and has a third through hole provided therein, and gaskets that are arranged in duplicate or more on each of the one side and the other side of the plate in a state that surrounds the cooling hole, and the electrical component body, the plate, the vibration-damping rubber, and the gasket are fixed to a housing, and at least a portion of the bottom surface of the electrical component body is in contact with the cooling liquid that flows through a cooling liquid flow path of the housing. The vibration-proof rubber and the gasket are fixed to the plate and are integrally formed. are. [Effects of the Invention]

[0011] According to the present invention, it is possible to provide an electrical component that can suppress leakage of cooling liquid and also achieve vibration isolation. [Brief explanation of the drawings]

[0013] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a perspective conceptual view of a vehicle 1 according to the first embodiment. The vehicle 1 of the embodiment is a vehicle powered by, for example, a fuel cell vehicle (FCV), an electric vehicle (BEV), or a hybrid vehicle (HEV). A fuel cell vehicle is a vehicle that uses hydrogen generated by a chemical reaction between hydrogen and oxygen. + (cation) and O -2 The car runs on a motor powered by electrical energy generated by the movement of negative ions (anions) between electrodes. The vehicle 1 has, at its front, right front wheel 2r and left front wheel 2l, which are steering wheels that change the direction of travel of the vehicle 1. At its rear, the vehicle 1 has right rear wheel 3r and left rear wheel 3l, which are driven wheels or drive wheels.

[0014] The vehicle 1 is provided with headlights 3h at the front that illuminate the road surface R ahead, and with rear lights 3a at the rear that illuminate the road surface R behind. The vehicle 1 is also provided with front bumpers 4f and rear bumpers 4r at the front and rear, respectively, that absorb the impact of a frontal and rear collision.

[0015] The vehicle 1 is controlled by a control unit (ECU) 1e. The rotation of the vehicle body 1h is detected by a yaw rate sensor (not shown), and the steering angle of the vehicle body 1h is detected by a steering angle sensor 1d. Wheel speed sensors (not shown) are installed on each rotating part, such as the axles of the right front wheel 2r and the left front wheel 2l, to detect the rotation speeds of the right front wheel 2r and the left front wheel 2l. Wheel speed sensors (not shown) are installed on each rotating part, such as the axles of the right rear wheel 3r and the left rear wheel 3l, to detect the rotation speeds of the right rear wheel 3r and the left rear wheel 3l.

[0016] Detection information (sensor current) of the yaw rate sensor, the steering angle sensor 1d, and each wheel speed sensor is input to the control device 1e. A fuel cell (not shown) is mounted on an under panel inside the body below the seat z of the vehicle 1. Directly above the fuel cell, a VCU (Voltage Control Unit) 4 for converting the power of the fuel cell into a desired voltage is disposed.

[0017] The VCU 4 is formed with an outer shell by a bottomed box-shaped VCU case (housing) 5 with an open upper part shown in FIG. 2. FIG. 2 is a perspective view of the VCU case 5. FIG. 3 is an enlarged partial cross-sectional view showing a main part of the cooling and anti-vibration structure in the VCU 4.

[0018] <VCU case (housing) 5> In the VCU case 5, electrical elements 6s such as capacitors, reactors, and power semiconductors that generate heat due to ripple current, Joule heat, switching loss, etc. are mounted. The electrical elements 6s are electrical component bodies 6h that are resin-sealed with resin. In order to cool the electrical component body 6h in which the electrical element 6s is sealed, a cooling liquid r (see FIG. 3) flowing through the cooling liquid flow path 5a is brought into direct contact with the electrical component body 6h.

[0019] Preventing leakage of the cooling liquid r to the outside, preventing vibration transmitted from the VCU case 5 fixed to the vehicle 1 to the electrical component body 6h, and improving the assembly workability around the electrical component body 6h are the aims (purposes) of the present invention. That is, the VCU case 5 is equipped with a structure (cooling liquid flow path 5a, cooling liquid r) for cooling the electrical component body 6h in which the heat-generating electrical element 6s is sealed. Furthermore, the electrical component 6 (see FIG. 3) has an anti-vibration structure for suppressing vibration transmitted from the VCU case 5 fixed to the vehicle body 1h (see FIG. 1) to the electrical component body 6h.

[0020] The electrical component 6 shown in Figure 3 has an electrical component body 6h and is equipped with a liquid leakage vibration suppression component 7 that has a function to prevent cooling liquid r from leaking to the outside (double seal gasket 7a) and a vibration-proof structure (vibration-proof rubber 7b).

[0021] <Cooling and vibration-proof structure for electrical component 6> The cooling and vibration-proof structure of the electrical component 6 will be described in detail below. A cooling liquid flow path 5a is formed in the VCU case 5 shown in Fig. 3. A cooling liquid r flows through the cooling liquid flow path 5a to cool the heat-generating electric component body 6h. The cooling liquid r, which has become hot through heat exchange with the electric component body 6h, is cooled by heat exchange with the outside air in a radiator (not shown).

[0022] As described above, the electric component body 6h is a molded product in which the electric element 6s is sealed, and at least the portion 6a (see FIG. 3) that comes into contact with the cooling liquid r is sealed with resin. Note that the electric element 6s includes an electronic element. 3, an electric element 6s is housed inside the electric component body 6h, and the electric component body 6h has a portion 6a1 where at least a part of the bottom surface is flat. A first through hole 6k for fixing is provided in the flat portion 6a1 of the electric component body 6h.

[0023] 3, a liquid leakage vibration suppression component 7 is provided between the VCU case 5 and the electric component main body 6h by threading a bolt 5b into the female thread portion 5m of the VCU case 5. As described above, the electric component main body 6h and the liquid leakage vibration suppression component 7 are collectively referred to as the electric component 6.

[0024] <Liquid leakage and vibration suppression parts 7> Fig. 4A is a plan view of the liquid leakage vibration suppression component 7. Fig. 4B is a cross-sectional view taken along line II of Fig. 4A.

[0025] FIG. 5A is a plan view of the support plate 7c, and FIG. 5B is an exploded side view of the vibration-isolating rubber 7b. As mentioned above, the liquid leakage vibration suppression component 7 shown in FIG. 4A is a single component (see FIG. 4B) formed by vulcanization bonding a double seal gasket 7a and four vibration-damping rubbers 7b to both sides of a single structural support plate 7c (see FIG. 5A). The double seal gasket 7a is a double-layered, annular rubber gasket for preventing the cooling liquid r from leaking to the outside.

[0026] The vibration-isolating rubber 7b prevents vibrations of the vehicle 1 (FIG. 1) from being transmitted to the electric component body 6h. <Support plate 7c>

[0027] The support plate 7c shown in FIG. 5A is made of, for example, a long, rectangular, thin metal plate. The support plate 7c has a circular protrusion 7c1 formed at each of the four corners, with a round hole 7c2 formed in the center of the circular protrusion 7c1. A large, long rectangular slot 7c3 (see FIG. 3) through which the cooling liquid r flows is formed in the center of the support plate 7c. Note that the shape is not limited to a rectangle.

[0028] The support plate 7c is formed from a metal sheet such as a stainless steel plate with a titanium layer formed on the surface. The support plate 7c may be made of other metals, such as rust-proofed ordinary steel plate (SS400) or general-purpose rolled structural steel plate (SPHC, etc.), other than stainless steel. The support plate 7c may also be made of a resin plate such as a reinforced plastic containing glass fiber or carbon fiber, as long as it meets certain requirements, such as strength, rust resistance, weather resistance, and resistance to deterioration over time. The material can be selected arbitrarily.

[0029] <Double seal gasket 7a> The double seal gaskets 7a shown in Figures 4A and 4B are installed on both sides of the support plate 7c. Specifically, the double seal gaskets 7a are disposed on one side of the support plate 7c and on the other side of the support plate 7c. The double seal gasket 7a has a first seal gasket 7a1 and a second seal gasket 7a2.

[0030] The double seal gasket 7a is bonded by vulcanization to one surface and the other surface of the support plate 7c. As shown in FIG. 4B, the first seal gasket 7a1 has a rectangular cross section and is formed in an annular shape surrounding the elongated hole 7c3 of the support plate 7c (see FIG. 4A). The second seal gasket 7a2 has a rectangular cross section and is formed in an annular shape outside the first seal gasket 7a1 to surround the first seal gasket 7a1.

[0031] In this way, the double seal gasket 7a is formed twice on the outer side of the elongated hole 7c3 of the support plate 7c. When the bolts 5b shown in Figure 3 are screwed into the female threads 5m of the VCU case 5, the double seal gaskets 7a installed on one and the other sides of the support plate 7c are pressed against and fixed to the VCU case 5 and the electric component body 6h. When pressed, the double seal gaskets 7a on one and the other sides of the support plate 7c elastically deform and come into tight contact with the VCU case 5 and the electric component body 6h. The tight contact of the double seal gaskets 7a reliably prevents leakage of the cooling liquid r (see Figure 3).

[0032] <Vibration-proof rubber 7b> The vibration-isolating rubber 7b shown in FIGS. 4A and 4B attenuates and prevents vibrations from being transmitted from the VCU case 5 to the electric components 6. The vibration-isolating rubber 7b includes a first vibration-isolating rubber 7b1 and a second vibration-isolating rubber 7b2. The first vibration-isolating rubber 7b1 is provided on one side of the support plate 7c, and the second vibration-isolating rubber 7b2 is provided on the other side of the support plate 7c.

[0033] The first vibration-isolating rubber 7b1 and the second vibration-isolating rubber 7b2 are provided at their centers with a first central hole 7b13 and a second central hole 7b23, each having approximately the same size as the round hole 7c2 of the circular protrusion 7c1. The first vibration-isolating rubber 7b1 has a rubber portion 7b11 and a washer portion 7b12. The rubber portion 7b11 is formed of, for example, rubber, which has a vibration damping effect. Specifically, the rubber portion 7b11 has a spring constant and internal resistance, and damps vibrations through energy loss and internal friction. For example, the rubber portion 7b11 may be made of natural rubber, butyl rubber, silicone rubber, or the like. However, the rubber portion 7b11 may be made of other materials as long as they have a vibration damping effect and satisfy predetermined conditions such as abrasion resistance, weather resistance, and resistance to deterioration over time.

[0034] The washer portion 7b12 is formed of rust-proofed ordinary steel plate (SS400), general rolled structural steel plate (SPHC, etc.), stainless steel plate (SUS), etc. However, the washer portion 7b12 may be made of other materials as long as it satisfies the required conditions such as strength, abrasion resistance, rust prevention, etc. The second vibration-isolating rubber 7b2 has a rubber portion 7b21 and a washer portion 7b22. The rubber portion 7b21 is made of the same material as the above-mentioned rubber portion 7b11. The washer portion 7b22 is made of the same material as the washer portion 7b12 described above.

[0035] As described above, the double seal gasket 7a and the vibration-damping rubber 7b (7b1, 7b2) shown in Figures 4A and 4B are integrally formed by vulcanization bonding to one side and the other side of the support plate 7c, respectively.

[0036] <Action and effect> As a result of the above, the liquid leakage vibration suppression component 7 not only has a vibration-damping effect, but also has the effect of cooling the electrical components 6 by bringing the cooling liquid r in the cooling liquid flow path 5a (see Figure 3) into direct contact with the electrical components 6. The liquid leakage vibration suppression component 7 is made into a single component by vulcanizing and bonding the double seal gasket 7a and the vibration-damping rubber 7b to both sides of the support plate 7c, which is sandwiched between the double seal gasket 7a and the vibration-damping rubber 7b. This makes it easy to manufacture.

[0037] Furthermore, assembly is easy because only one liquid leakage vibration suppression component 7 is required. This reduces the number of components, making production easier. It is also possible to improve the workability when assembling the electrical components 6. This allows for a highly productive configuration. In addition to the vibration-damping effect of the double seal gasket 7a, even if the cooling liquid r in the cooling liquid flow path 5a is directly in contact with the electrical component body 6h for cooling, the sandwiched liquid leakage vibration suppression component 7 can suppress deformation of the double seal gasket 7a due to water pressure. Furthermore, by making the double seal gasket 7a shown in Figures 4A and 4B a double structure, even if the single first seal gasket 7a1 leaks, the second seal gasket 7a2 can reliably suppress leakage of the cooling liquid r. Therefore, it is possible to improve the quality of the electrical component body 6h, which requires vibration damping and cooling, as shown in Figure 3.

[0038] Although the first embodiment exemplifies the double seal gasket 7a, a multi-layer seal gasket having three or more layers may also be used.

[0039] <<Second embodiment>> The liquid leakage vibration suppressing component 27 of the second embodiment is configured to be assembled, unlike the liquid leakage vibration suppressing component 7 of the first embodiment which is fixed integrally. The other components are unchanged, so the same components are designated by reference numerals in the 20s, and redundant explanations will be omitted.

[0040] Fig. 6A is a view of the liquid leakage vibration suppression component 27 of the second embodiment as viewed from one side, and Fig. 6B is an enlarged cross-sectional view taken along the line II-II of Fig. 6A. FIG. 7 is an enlarged partial cross-sectional view of the line II in FIG. 6A, showing the process of assembling the liquid leakage vibration suppression component 27.

[0041] A continuous annular double seal gasket 27a is disposed on one side and the other side of a support plate 27c of a second embodiment shown in FIGS. 6A and 6B so as to surround a central elongated hole 27c3. More specifically, an annular first seal gasket 27a1 is disposed on one surface of the support plate 27c around a central elongated hole 27c3. Here, a plurality of first positioning projections t1 (see FIG. 6B) for the first seal gasket 27a1 are formed by drawing on one surface of the support plate 27c. The first positioning projections t1 facilitate positioning of the first seal gasket 27a1 on the support plate 27c.

[0042] A continuous annular second seal gasket 27a2 is disposed on the support plate 27c outside the first seal gasket 27a1. A plurality of second positioning projections t2 (see FIG. 6B) for the second seal gasket 27a2 are formed by drawing on one surface of the support plate 27c. The second positioning projections t2 facilitate positioning of the second seal gasket 27a2 on the support plate 27c. Similarly, an annular first seal gasket 27a1 and an annular second seal gasket 27a2 are arranged to surround the elongated hole 27c3 on the other surface of the support plate 27c.

[0043] The position of the first seal gasket 27a1 relative to the support plate 27c is determined by a first positioning projection t1 formed on the other surface of the support plate 27c, and the position of the second seal gasket 27a2 relative to the support plate 27c is determined by a second positioning projection t2 formed on the other surface of the support plate 27c.

[0044] Support plate 27c shown in FIG. 6A has circular protrusions 27c1 formed at each of the four corners, and circular hole 27c2 formed in the center of circular protrusions 27c1. A first vibration-isolating rubber 27b1 is provided on one surface of the circular protrusion 27c1, and a second vibration-isolating rubber 27b2 is provided on the other surface of the circular protrusion 27c1. The first vibration-isolating rubber 27b1 has a first center hole 27b13 formed in the center. The second vibration-isolating rubber 27b2 has a second center hole 27b23 formed in the center.

[0045] As shown in Fig. 6B, a first vibration-proof rubber 27b1 is arranged on one side of the support plate 27c so that the first center hole 27b13 is approximately aligned with the round hole 27c2 of the support plate 27c. Here, a first rubber positioning protrusion b1 is formed on one side of each of the four circular protrusions 27c1 by burring or drawing. The first vibration-proof rubber 27b1 A recess 27b11 (see Fig. 6B and Fig. 7) for the first rubber positioning protrusion b1 is recessed in the first rubber positioning protrusion b1. As a result, the first rubber positioning protrusion b1 is formed outside the bolt 5b (see Fig. 3), and the first rubber positioning protrusion b1 does not get in the way of the bolt 5b. As shown in FIGS. 7 and 6B, the first rubber positioning protrusions b1 make it easy to install the four first vibration-isolating rubbers 27b1 on one surface of the support plate 27c.

[0046] Similarly, second vibration-damping rubbers 27b2 are arranged on the other side of support plate 27c so that the second center hole 27b23 is approximately aligned with the circular hole 27c2 of support plate 27c. Here, second rubber positioning protrusions t3 for second vibration-damping rubbers 27b2 are formed on the other side of four circular protrusions 27c1 by burring or drawing. As shown in FIGS. 7 and 6B, second rubber positioning protrusions t3 facilitate the installation of the four second vibration-damping rubbers 27b2 on the other side of support plate 27c. Note that FIGS. 6B and 7 show a case where first vibration-damping rubber 27b1 is positioned by first rubber positioning protrusion b1 by burring. Also shown is a case where second vibration-damping rubber 27b2 is positioned by second rubber positioning protrusion t3 by drawing.

[0047] In addition, both the first vibration-damping rubber 27b1 and the second vibration-damping rubber 27b2 may be positioned by positioning protrusions formed by drawing, or by positioning protrusions formed by burring, and the form of the positioning components can be selected arbitrarily.

[0048] <Application of industrial adhesives and industrial double-sided tapes> The double seal gasket 27a may be attached to one side and the other side of the support plate 27c by applying industrial adhesive or industrial double-sided tape to the attachment surface of the double seal gasket 27a to the support plate 27c and / or to the attachment surface of the double seal gasket 27a on the support plate 27c. Similarly, industrial adhesive or industrial double-sided tape may be applied to the mounting surfaces of first vibration-damping rubber 27b1 and second vibration-damping rubber 27b2 on support plate 27c and / or the mounting surfaces of support plate 27c on which first vibration-damping rubber 27b1 and second vibration-damping rubber 7b2 are mounted, thereby mounting first vibration-damping rubber 7b1 and second vibration-damping rubber 7b2 on one and the other sides of support plate 27c. Applying industrial adhesive or industrial double-sided tape reliably secures double seal gasket 27a and first vibration-damping rubber 7b1 and second vibration-damping rubber 7b2 to support plate 27c. This facilitates assembly and improves workability.

[0049] <Action and effect> From the above, as in the first embodiment, the liquid leakage vibration suppression component 27 not only has a vibration damping effect, but also can suppress leakage of the cooling liquid r (see FIG. 3) in the cooling liquid flow path even when the cooling liquid r is cooled by directly contacting the electrical component body 6h. Furthermore, in assembly, it is only necessary to assemble the liquid leakage vibration suppression component 27, which makes assembly easy and improves workability. In addition to the vibration-damping effect of the double seal gasket 27a, even if the cooling liquid r in the cooling liquid flow path 5a (see FIG. 3) is cooled by directly contacting it with the electric component body 6h, deformation of the double seal gasket 27a due to water pressure can be suppressed by the sandwiched liquid leakage vibration suppression component 27. Furthermore, by making the double seal gasket 27a shown in FIGS. 6A and 6B a double structure, leakage of the cooling liquid can be reliably suppressed.

[0050] <<Other embodiments>> 1. In the above embodiment, the electrical component 6 is described as being applied to a vehicle 1, but it can also be effectively applied to any other equipment other than a vehicle 1, such as a ship, heavy machinery, machine tools, general machinery, airplanes, or flying objects.
