Description

  The present invention relates to a heat dissipation structure for an electrolytic capacitor, an illumination lamp, an illumination device, and a method for manufacturing the illumination lamp.

  2. Description of the Related Art Conventionally, various heat radiating structures for radiating heat from an electrolytic capacitor are known. Generally, when a ripple current is applied to an electrolytic capacitor for a long time or a large current is applied, heat is generated and the temperature of the electrolytic capacitor rises. Further, when an electronic component having a large calorific value is disposed in the vicinity of the electrolytic capacitor, the temperature of the electrolytic capacitor rises due to the influence of heat generated by the electronic component. When the temperature of the electrolytic capacitor rises excessively, various electrical characteristics such as an increase in dielectric loss tangent and a decrease in capacitance are deteriorated, resulting in a problem that the operating life of the electrolytic capacitor is shortened. This means that it becomes difficult to maintain the performance and quality of an electronic circuit or an electronic device including an electrolytic capacitor.

  Therefore, for example, as described in Patent Documents 1 and 2 below, a cooling (heat radiation) technique aimed at suppressing the temperature rise of the electrolytic capacitor has been proposed. In Patent Document 1, a metal case of an electrolytic capacitor is covered with a bottomed cylindrical metal heat dissipating member, and the metal heat dissipating member is provided with an attachment fixing portion connected to the body portion. A configuration is disclosed in which a convex portion is provided on the inner surface of the portion, the convex portion is fitted into a fixing annular concave groove of a sealing body that seals the opening of the metal case, and the electrolytic capacitor body is supported. However, the metal radiator and the electrolytic capacitor are in contact with each other, and no special configuration is provided between them.

  Patent Document 2 discloses a configuration in which a capacitor element is housed in an outer case, and a heat conductive material is interposed between the outer case and the capacitor element in contact with them. However, in this configuration, the outer case is covered with a heat conductive material provided around the capacitor element, and the capacitor element was wound with a separator interposed between the anode foil and the cathode foil. Is. In other words, the configuration of Patent Document 2 is a device in which the internal structure of one electrolytic capacitor is devised.

  However, the conventional electrolytic capacitor heat dissipation structure has low versatility, and as a result, has difficulty in mass production. Specifically, when the technique according to Patent Document 1 is used, since the shape of the metal radiator has a specific dimension, only an electrolytic capacitor having an external dimension adapted to the dimension of each metal radiator can be accommodated. In addition, a product on which an electrolytic capacitor is mounted needs to have a space that can accommodate a metal radiator that houses the electrolytic capacitor. That is, a metal radiator having different specifications according to the dimensions of the electrolytic capacitor and the dimensions of the component placement area is required, which increases manufacturing costs and management costs.

(Configuration of the illumination lamp 100)
As shown in FIG. 1, the illumination lamp according to the first embodiment of the present invention is a bulb-type LED lamp. The illumination lamp 100 includes a lighting circuit 6, a light source 7, an inner housing portion 8, a base portion 9, an outer housing portion 10, and a globe 11.

  The illumination device including the illumination lamp 100 is the illumination device according to the first embodiment of the present invention. The illuminating device according to the first exemplary embodiment includes a reflector, a casing, a power supply connection unit, and a lamp holding unit (such as a base) in addition to the illumination lamp 100.

  The electrolytic capacitor 4 is connected to the lighting circuit 6. The globe 11 is a translucent member that transmits light emitted from the light source 7 and is disposed so as to cover the light source 7 on the light emission side. The lighting circuit 6 converts commercial power supplied via the base unit 9 into drive power for driving the light source 7 and supplies the converted power to the light source 7. The inner housing portion 8 and the outer housing portion 10 hold the lighting circuit 6 so as to be included, and are fitted with the globe 11 and the base portion 9 to form an internal space.

  In the first embodiment, the light source 7 includes a light emitting diode (hereinafter referred to as an LED) 71 that is a light emitting means and an LED substrate 70 on which the LED 71 is placed. The components of the light source 7 include a wiring member (not shown), a mounting member (not shown), and electronic components required according to the design specifications of the illumination lamp. The wiring member (not shown) is a wire harness or a connector that is electrically connected to the lighting circuit 6 and transmits driving power from the lighting circuit 6 to the light source 7. The attachment member (not shown) is a screw or the like for attaching the LED substrate 70 to the inner housing portion 8 (or the outer housing portion 10).

  The globe 11 is made of a material such as glass or resin. When using a resin, polycarbonate or acrylic is selected according to the product specifications. The globe 11 has translucency, transmits light emitted from the light source 7, and has a function of diffusing, condensing, and reflecting light as necessary. These functions may be applied directly to these substrates as a diffusion layer (or diffusion surface), a lens, a reflection layer (or reflection surface), etc. when molding the glass or resin that is the substrate of the globe 11, You may comprise combining another member on the surface of a base material. The globe 11 constitutes a part of the outer portion of the illumination lamp 100 together with the outer casing portion 10 and the base portion 9.

  The inner housing portion 8 is a resin housing that is molded using a resin material such as plastic. The inner housing portion 8 has an opening, and includes a holding structure (not shown) that holds the lighting circuit 6 inserted from the opening. A predetermined gap is provided between the inner surface of the inner casing portion 8 and the circuit components included in the lighting circuit 6 except for a portion (for example, a circuit board) held by the holding structure. That is, the lighting circuit 6 is contained and held in the internal space of the inner casing 8 in a state where mechanical stress is not applied to the circuit components.

  The outer housing part 10 is disposed outside the inner housing part 8. The outer housing part 10 constitutes a part of the outer part of the illumination lamp 100 together with the globe 11 and the base part 9. The outer casing 10 is formed using a metal material such as aluminum. The outer casing unit 10 has a function of making the structure of the illumination lamp 100 robust and transmitting heat generated by the light source 7 and the lighting circuit 6 to the outside. Fins (not shown) may be provided on the outer surface of the outer casing 10. By providing the fins, the effects of those functions can be further promoted.

  The base portion 9 has a structure that fits into a lighting fixture (not shown) such as a socket. The base portion 9 is an input end that inputs commercial power to the illumination lamp 100 via a lighting fixture.

  The lighting circuit 6 has an AC-DC converter circuit. This AC-DC converter can convert AC power supply power, which is commercial power, into DC power for driving the LED 71. Accordingly, the lighting circuit 6 converts the commercial power input from the base unit 9 into driving power for driving the light source 7 and supplies the driving power to the light source 7.

  Preferably, the lighting circuit 6 has a load fluctuation detection function and a control function for controlling the drive current output from the AC-DC converter circuit in accordance with the load fluctuation in order to drive the LED 71 stably. Preferably, the lighting circuit 6 has a filter function for removing or reducing noise that flows in and / or out through a supply path of commercial power. The outer dimensions of the electrolytic capacitor 4 depend on the capacitance value of the electrolytic capacitor 4 and voltage specifications. The capacitance value and voltage specification of the electrolytic capacitor 4 are determined according to the design specification of the illumination lamp.

  FIG. 2 is a perspective view showing the electrolytic capacitor according to the first embodiment of the present invention. The electrolytic capacitor 4 includes a cylindrical outer shell 4a having a diameter R and a height T, and leads 4b. A capacitor element connected to the lead 4b is housed inside the cylindrical outer shell 4a. The heat conductive member 1 is affixed on the side peripheral surface of the cylindrical outer shell 4a.

  When the heat conducting member 1 is bonded to the cylindrical shell 4a (aluminum case) of the electrolytic capacitor 4, at least the heat conducting member 1 does not block the pressure valve 5 (synonymous with a safety valve and an explosion-proof valve) of the electrolytic capacitor 4. . That is, in the present embodiment, the heat conducting member 1 is wound only on the side peripheral surface of the cylindrical outer shell 4a of the electrolytic capacitor 4 in a limited manner. This is because the pressure valve 5 of the electrolytic capacitor 4 is not prevented from functioning normally when an abnormality occurs in the operation of the electrolytic capacitor 4.

  In the illumination lamp 100 according to the first embodiment, the electrolytic capacitor 4 smoothes the input commercial power, or generates a pulsating flow of driving power supplied to the light source 7 in order to drive the LED 71 that is the light emitting means of the light source 7. It has a function to reduce. By supplying stable direct-current power to the light source 7, there is an effect of realizing stable light emission.

  In the illumination lamp 100 according to the first embodiment, the electrolytic capacitor 4 is included in the inner space of the inner housing portion 8 on the base 9 side. This arrangement is suitable in consideration of the dimensional restrictions associated with the miniaturization of the illumination lamp 100 and the purpose of improving the operational reliability of the electrolytic capacitor 4 by being separated from the light source 7 as the main heat source. .

  In addition, the function of the electrolytic capacitor 4 is not limited to the above-described one, and when the light source 7 has a light emitting unit other than the LED, the electrolytic capacitor 4 may have other uses and functions. A wiring member (not shown) that is electrically connected to the base portion 9 and transmits commercial power from the base portion 9 to the lighting circuit 6 is also a component of the lighting circuit 6.

  The heat conducting member 1 bonded to the entire circumference of the tubular outer shell 4a (aluminum case) of the electrolytic capacitor 4 fills the gap between the electrolytic capacitor 4 and the inner surface of the inner housing portion 8 so that the tube of the electrolytic capacitor 4 is filled. The outer shell 4a (aluminum case) and the inner surface of the inner casing 8 are held in close contact with each other. That is, the cylindrical outer shell 4a (aluminum case), the heat conducting member 1, the inner housing portion 8, and the outer housing portion 10 (and / or the base portion 9) of the electrolytic capacitor 4 are continuously connected to the outside of the illumination lamp 100. A heat transfer path is formed and cooling of the electrolytic capacitor 4 is promoted.

  The electrolytic capacitor 4 is a component of the lighting circuit 6 and is placed on the circuit board of the lighting circuit 6. In this state, the heat conducting member 1 is bonded to the entire circumference of the cylindrical shell 4a (aluminum case) of the electrolytic capacitor 4. The lighting circuit 6 is held in the internal space of the inner housing portion 8 so that the electrolytic capacitor 4 bonded with the heat conducting member 1 is included in the base portion 9 side. The circuit board of the lighting circuit 6 is held so that mechanical stress is not applied to the circuit components of the lighting circuit 6. Specifically, the lighting circuit 6 is held by a holding portion that is integrally formed on the inner surface of the inner housing portion 8.

  A gap between the pressure valve 5 of the electrolytic capacitor 4 and the inner surface of the inner housing portion 8 is provided in a state where the lighting circuit 6 is held in the inner space of the inner housing portion 8. This gap is a gap that does not hinder the function of the pressure valve 5 of the electrolytic capacitor 4, that is, the pressure valve 5 can be opened. The pressure valve 5 is provided to operate when an abnormality occurs in the operation of the electrolytic capacitor 4.

(Configuration of heat conduction member 1)
3 and 4 show the configuration of the heat conducting member 1. As shown in FIG. 4, the heat conductive member 1 has a heat conductive resin 2 and an adhesive tape 3.

  The heat conductive resin 2 has a property capable of bending and bending, and is a material having flexibility and flexibility and stretchability. Specifically, this material is a resin material having electrical insulation, and is, for example, a silicone oil or a fluorine-based inert liquid that exhibits a semi-solid gel or a liquid (with relatively high viscosity). It is preferable that the heat conductive resin 2 is nonflammable.

  Further, the heat conductive resin 2 may be mixed with a solid material (for example, in the form of particles or powder) for the purpose of increasing the heat capacity within a flexible range.

  The adhesive tape 3 is shown in two as shown in the cross-sectional view, but this shows a surface cover and an adhesive layer (or adhesive layer) provided under the cover. The surface of the adhesive layer appears by removing the cover.

  As shown in FIG. 4, the thermally conductive resin 2 has a long side length dimension L, a width dimension W, and a thickness dimension D. Each of these dimensions is set in advance. The length dimension L is substantially the same as the outer peripheral dimension of the cylindrical outer shell 4a (aluminum case) of the electrolytic capacitor 4 to be cooled. The width dimension W is substantially the same dimension below the height dimension of the cylindrical outer shell 4a (aluminum case) of the electrolytic capacitor 4 to be cooled. Since the cylindrical shell 4a (aluminum case) of the electrolytic capacitor 4 has a substantially cylindrical shape having a diameter R and a height T, L ≦ π × R and W ≦ T.

The heat conducting member 1 has a surface whose size is defined by a length dimension L and a width dimension W. One surface of the heat conductive member 1 (surface) comes into contact with the cylindrical outer 4a of the electrolytic capacitor 4 (aluminum case), the resin of the inner casing is a heat member release the other surface of the heat conducting member 1 (the back surface) of Eight. As a result, a heat dissipation path from the electrolytic capacitor 4 to the external atmosphere is formed together with the outer casing (metal casing) 10 and the base 9.

Thickness D, when the thermally conductive resin 2 surface is brought into contact with the entire circumference of the cylindrical outer 4a of the electrolytic capacitor 4 (aluminum case), heating members release the cylindrical outer 4a of the electrolytic capacitor 4 (inner The thickness is equal to or greater than the maximum dimension of the gap between the casing (resin casing) 8, the outer casing (metal casing) 10, and the base 9). Actually, it is set in consideration of the flexibility of the heat conductive resin 2.

  An adhesive tape 3 is disposed on the surface of the heat conductive resin 2 in order to bond the heat conductive member 1 to the cylindrical shell 4a (aluminum case) of the electrolytic capacitor 4. The adhesive tape 3 has a long side length dimension l and a width dimension w that are slightly smaller than the dimensions L and W so as to be disposed in the surface of the heat conductive resin 2. That is, the relationship of l ≦ L and w ≦ W is established. The adhesive tape 3 is an example, and an adhesive layer for attaching the heat conductive resin 2 to the electrolytic capacitor 4 may be provided.

[Production Method of Embodiment 1]
FIG. 5 is a flowchart for explaining the method of manufacturing the illumination lamp according to the first embodiment of the present invention.

  In the flowchart of FIG. 5, first, a preparation process for preparing components of the illumination lamp 100 is performed. Among these, step S100 prepares components other than the heat conductive member 1. FIG. That is, preparation of the electrolytic capacitor 4, the lighting circuit 6, the light source 7, the inner housing part 8, the base part 9, the outer housing part 10, and the globe 11 to be finally assembled.

  On the other hand, steps S102, S104, and S106 are steps for preparing the heat conducting member 1. Specifically, in step S102, the heat conducting member 1 is designed. The heat conductive member 1 includes a heat conductive resin 2 and an adhesive tape 3. As described with reference to FIG. 4, the thermally conductive resin 2 has a long side length dimension L, a width dimension W, and a thickness dimension D. Each of these dimensions is determined by the relationship with the component prepared in step S100 as described above. The dimensions of the adhesive tape 3 are also designed to have a long side length dimension l and a width dimension w that are slightly smaller than the dimensions L and W so as to be disposed within the surface of the heat conductive resin 2.

Next, in step S102, the heat conductive resin 2 is formed by cutting the resin material having the thickness D according to the dimensions L and W determined in step S102. As a manufacturing method, it can manufacture by methods, such as punching out resin of a large area or cutting long resin.
Further, in step S106, the adhesive tape 3 is cut according to the dimensions l and w and attached to the heat conductive resin 2.
As described above, the components of the illumination lamp 100 including the heat conducting member 1 can be prepared.

  Next, the process of sticking the heat conductive resin 2 to the cylindrical outer shell 4a of the electrolytic capacitor 4 is performed (step S108). This attachment process is a process of attaching the heat conducting member 1 so as to be in contact with the cylindrical outer shell 4a along the circumferential direction of the cylindrical outer shell 4a. This is to prevent the pressure valve 5 from being blocked.

  Then, the component part of the illumination lamp 100 mentioned above is assembled using the electrolytic capacitor 4 which attached the heat conductive member 1 (step S110). Thereby, the illumination lamp 100 is completed. In this assembling process, the electrolytic capacitor 4 is arranged in the inner casing 8 and the heat conducting member 1 is sandwiched between the cylindrical outer shell 4 a and the inner surface of the inner casing 8.

  According to the embodiment described above, the heat conducting member 1 is interposed in the gap between the cylindrical outer shell 4a of the electrolytic capacitor 4 and the inner housing portion 8, and a heat conduction path between them can be secured. . Since this heat conducting member 1 can absorb the difference in dimensions of the electrolytic capacitor 4 and the inner housing part 8, it is excellent in productivity.

  In the first embodiment, the heat conduction medium of the heat conduction member 1 bonded to the entire circumference of the cylindrical shell 4a (aluminum case) of the electrolytic capacitor 4 has flexibility that can be bent and bent. doing. Since the heat conductive resin 2 which is a resin material is used, the cylindrical outer shell 4a (aluminum case) of the electrolytic capacitor 4 and the inner casing portion 8 are filled so as to fill a gap between the electrolytic capacitor 4 and the inner surface of the inner casing portion 8. In this way, the electrolytic capacitor 4 (the cylindrical outer shell 4a (aluminum case)), the heat conducting member 1, the inner housing portion 8, and the outer housing portion can be formed. 10 (and / or the base portion 9) can form a continuous heat transfer path to the outside of the illumination lamp 100, and promote cooling of the electrolytic capacitor 4.

  According to the present embodiment, even in an environment in which a ripple current is applied to the electrolytic capacitor for a long time or a large current is applied and the temperature of the electrolytic capacitor 4 rises due to heat generation, the electrolytic capacitor 4 is used as an illumination lamp. Therefore, the electrolytic capacitor 4 does not cause an excessive temperature rise. Alternatively, even in an environment where an electronic component having a large calorific value is disposed in the vicinity of the electrolytic capacitor 4 and the temperature of the electrolytic capacitor 4 rises due to the influence of heat generated by the electronic component, the electrolytic capacitor 4 can be used as an illumination lamp. Therefore, the electrolytic capacitor 4 does not cause an excessive temperature rise.

As a result, the operating life of the electrolytic capacitor 4 can be extended, and the performance and quality of the electronic circuit and electronic device including the electrolytic capacitor 4 can be stably maintained over a long period of time.
Specifically, for example, even when the amount of heat generated in the lighting circuit is relatively small and it is not necessary to fill with a cooling filler such as silicon or epoxy for cooling the lighting circuit, only the electrolytic capacitor promotes cooling. Thus, the operating life of the electrolytic capacitor and the lighting circuit (including the electrolytic capacitor) and the lighting lamp can be extended.

  Moreover, according to this Embodiment, it was set as the heat conductive resin 2 which is the resin material which has the flexibility and electric insulation which can be bent and the heat conductive medium of the heat conductive member 1 is bent. Therefore, it can be manufactured at low cost, and a plurality of types of electrolytic capacitors having different external dimensions can be accommodated, and even products having different shapes and dimensions can be accommodated. As a result, the same or a few types of heat conducting members can be used for many types of electrolytic capacitors 4 and can be used for many types of products.

Since this embodiment can be easily manufactured and assembled, the manufacturing process can be simplified and the manufacturing quality can be stabilized. That is, a configuration is widely used in which a circuit component including an electrolytic capacitor is potted (filled) with a resin material such as silicon or polyurethane to radiate heat from the electrolytic capacitor or other circuit components. However, such a configuration requires a dedicated equipment and process for potting (filling) a resin material into a product, and work capacity. Therefore, there is a problem from the viewpoint of increasing the manufacturing cost and mass productivity.
In this respect, according to the present embodiment, it is sufficient to wrap and paste the heat conductive resin 2 around the electrolytic capacitor 4 and insert it between the inner housing parts 8, so that the manufacturing process is simpler than potting. It becomes.

  Furthermore, in this embodiment, since the heat conducting medium of the heat conducting member 1 is bonded to the cylindrical outer shell 4a excluding the pressure valve of the electrolytic capacitor 4, the electrolytic capacitor 4 is electrolyzed when an abnormality occurs in the operation of the electrolytic capacitor 4. The pressure valve of the capacitor 4 can function normally.

  In the present embodiment, the electrolytic capacitor 4 and the circuit components having the electrolytic capacitor 4 and the illumination lamp can be extended in life, quality can be improved, and cost can be reduced.

  Lowering costs includes reducing material costs (and resulting manufacturing costs). The reduction of the material cost includes the meaning of relaxing the heat resistance specification of the electrolytic capacitor (that is, adopting an inexpensive electrolytic capacitor). This is because, according to the present embodiment, the electrolytic capacitor can be cooled or heat-dispersed to lower the operating environment of the electrolytic capacitor, so that an inexpensive electrolytic capacitor with low heat resistance can be used.

[Modification of Embodiment 1]
In the first embodiment, the cylindrical shell 4a of the electrolytic capacitor is an aluminum case, but the present invention is not limited to this, and the cylindrical shell 4a may be an exterior sleeve.

  In Embodiment 1, the heat conductive resin 2 is formed of a flexible material. Flexibility is a property that allows bending and bending. On the other hand, instead of the heat conductive resin 2, an elastic flat body made of an elastic material and capable of elastic deformation may be attached to the cylindrical outer shell 4 a of the electrolytic capacitor 4 in the same manner as the heat conductive resin 2. Any material may be used as long as it is flexible and stretchable enough to be deformed into a cylindrical shape along the side peripheral surface of the electrolytic capacitor 4 and further has heat dissipation (high thermal conductivity) and electrical insulation.

  In addition, the variation of the shape of the heat conductive resin 2 can be considered. For example, the heat conductive resin 2 may have a quadrangular prism shape. Further, the heat conductive resin 2 may have a rectangular parallelepiped shape.

  FIG. 16 is a front view for explaining a modification of the embodiment of the present invention, and is a diagram showing a variation of the configuration of the heat conducting member. FIG. 16A illustrates the configuration of the electrolytic capacitor 4 according to the first embodiment so that the pressure valve 5 is viewed from the front. FIG. 16B is a diagram showing an electrolytic capacitor 41 having a heat conducting member 1g having a quadrangular prism (cuboid) shape.

  The heat conductive member 1g can be formed of a heat conductive material such as a resin as described in the heat conductive member 1 in the first embodiment. Since the volume of the heat conducting member can be increased by making the shape a quadrangular prism or a rectangular parallelepiped, the heat dissipation can be improved as compared with the cylindrical shape. That is, by making the outer shape a quadrangular prism, the area of the plane portion becomes larger than one time. If the volume of the heat conducting member is the same length (diameter), and the thinnest part of the heat conducting member and the long part (that is, the dimension in the depth direction of the paper in FIG. 16 and the width dimension W) are the same, The square column shape is inevitably larger than the cylindrical shape.

  Here, it is assumed that the inner diameter of the inner housing portion 8 of the illumination lamp 100 according to the first embodiment is increased by the volume increase of the heat conducting member 1g having a quadrangular prism shape. Then, when considering the ratio occupied by the material of the inner casing 8 (plastic etc.) and the ratio of the material of the heat conductive member 1g (substantially heat conductive resin excluding the adhesive tape), this deformation The example can have more heat conducting members. For this reason, it can be set as the heat dissipation structure which took in more heat conductive members with higher heat dissipation. As a result, the heat dissipation performance of the electrolytic capacitor 4 can be improved.

  FIG. 16C is a diagram for explaining a cross-sectional area difference between the cylindrical heat conductive member 1 and the square columnar heat conductive member 1g when the thinnest portion of the heat conductive member is the same. The sectional area of the heat conducting member 1 shown in FIG. 16 (a) is Sa, and the sectional area of the heat conducting member 1g shown in FIG. 16 (b) is Sb. The radius of the cylindrical outer shell 4a of the electrolytic capacitor 4 is r. Further, the thinnest part of the heat conducting members 1 and 1g is t. However, since the heat conducting member 1 has a uniform thickness, the thinnest portion has a uniform t. In FIG. 16C, the hatched region is area Sb−area Sa, that is, an area increase. When Sb-Sa is calculated using r and t, the following equation (1) is established.

Sb−Sa = (4-π) (r + t) ² > 0 (1)

  As shown on the right side of Expression (1), Sb-Sa is always a positive value. Therefore, the sectional area Sb is always larger than the sectional area Sa. Therefore, the use of the rectangular column shape can surely increase the heat conductive material.

At least, even if the tubular heat conducting member 1c is stretched to cover the tubular outer shell 4a of the electrolytic capacitor 4, it is required to be elastically deformed to such an extent that it can be restored to ensure adhesion to the tubular outer shell 4a. Thereby, it is possible to adhere and fix to the cylindrical outer shell 4a (aluminum case) of the electrolytic capacitor 4 without using an adhesive means such as an adhesive tape. Thereby, in addition to the automation of the manufacture of the heat conducting member 1c and the reduction of the manufacturing cost, there is an effect of reducing the material cost.

Further, the relationship between the width W of the heat conductive braid 20 and the height T of the cylindrical outer shell 4a is W ≦ T.

  By using the heat conductive braided body (cylindrical metal mesh) 20 as the heat conductive member 1d, cooling of the electrolytic capacitor 4 is further promoted. The thermally conductive braided body (cylindrical metal mesh) 20 has elasticity, and can be tightly fixed to the cylindrical outer shell 4a (aluminum case) of the electrolytic capacitor 4 without providing an adhesive layer such as an adhesive tape. is there.

The heat conductive braided body (cylindrical metal mesh) 20 has elasticity and is in close contact with the inner surface of the inner housing portion 8 to form a heat dissipation path. At this time, the heat conductive braided body (tubular metal mesh) 20 does not block the pressure valve 5 of the electrolytic capacitor 4.

  As for the manufacturing method according to the fifth embodiment, referring to the flowchart of FIG. 5 showing the manufacturing method according to the first embodiment, the preparation steps (steps S102 and S106) for preparing the heat conducting member and the heat conducting member 1d are prepared. The content of the attachment process (S108) attached to the electrolytic capacitor 4 is different. The heat conductive braided body 20 can be obtained by cutting a heat conductive braided body (cylindrical metal mesh), which has been manufactured in a cylindrical shape in advance, with a predetermined length (length of width W).

  In the fifth embodiment, the heat conducting member 1d has a single-layer structure, but the present invention is not limited to this and may have a plurality of layers. That is, a plurality of heat conducting members 1 d having different diameters may be overlapped and covered on the cylindrical outer shell 4 a of the electrolytic capacitor 4.

In the same manner as in the first to third embodiments, the heat conductive resin 1 d is cut from the metal mesh flat body in the same manner as the heat conductive resin flat body is cut and wound around the cylindrical shell 4 a of the electrolytic capacitor 4. The electrolytic capacitor 4 may be wound around the cylindrical outer shell 4a with an adhesive layer (adhesive tape) interposed therebetween.

Embodiment 6 FIG.
FIG. 11 is an exploded perspective view showing the configuration of the heat conducting member 1e according to the sixth embodiment of the present invention. FIG. 12 is a perspective view showing the configuration of the electrolytic capacitor 4 to which the heat conducting member 1e according to the sixth embodiment of the present invention is attached. Other configurations and manufacturing methods are the same as those in the first embodiment, and thus description thereof is omitted.

  As shown in FIG. 11, the heat conductive member 1e is formed by stacking two heat conductive braided bodies (cylindrical metal meshes) 20a and 20b and a heat conductive resin 2c, which are manufactured in a long cylindrical shape in advance. It is configured. That is, the heat conducting member 1e has a cylindrical three-layer structure.

  As shown in FIG. 12, the heat conductive member 1e is attached to the electrolytic capacitor 4, so that the heat conductive resin 2c is in contact with the cylindrical outer shell 4a along the circumferential direction of the cylindrical outer shell 4a and the inner shell 4a. It will be sandwiched between the inner surface of the body part 8. And the heat conductive braided bodies 20a and 20b are located on the outer side and the inner side of the heat conductive resin 2c, respectively. Therefore, the heat conductive braided bodies 20a and 20b are sandwiched between the cylindrical outer shell 4a and the inner surface of the inner housing portion 8 while contacting the cylindrical outer shell along the circumferential direction of the cylindrical outer shell 4a. . As a result, the heat conducting member 1e having a cylindrical three-layer structure is sandwiched between the cylindrical outer shell 4a of the electrolytic capacitor 4 and the inner surface of the inner housing portion 8, thereby constituting a heat transfer path therebetween. Can do.

  By using the heat conductive braids (cylindrical metal mesh) 20a, 20b and the heat conductive resin 2c as the heat conductive member 1e, the cooling of the electrolytic capacitor 4 is further promoted.

  Moreover, it is preferable to employ a material having a large heat capacity for the second layer. This is because the effect of promoting heat dispersion of the electrolytic capacitor 4 is exhibited, and a resin material having a high heat capacity is selected as the thermally conductive resin 2c from such a viewpoint.

  As for the manufacturing method according to the sixth embodiment, referring to the flowchart of FIG. 5 showing the manufacturing method according to the first embodiment, the preparation steps (steps S102 and S106) for preparing the heat conducting member and the heat conducting member 1e are prepared. The content of the attachment process (S108) attached to the electrolytic capacitor 4 is different.

  In order to manufacture the heat conductive braids 20a and 20b and the heat conductive resin 2c, first, the cylindrical shapes having different inner diameters R3, R4, and R5 are cut to a predetermined length (width W). To do. However, the inner diameter has a relationship of R3 ≦ R4 ≦ R5, that is, the inner diameter R5 is the largest, and as shown by the arrow in FIG. is necessary. Thereafter, the heat conductive braided body (cylindrical metal mesh) 20a is set as the innermost side, and the heat conductive resin 2c and the heat conductive braided body (cylindrical metal mesh) 20b are stacked in this order. At this time, the inner diameter R3 and the width W of the heat conductive braid 20a are set such that R3 ≦ R and W ≦ T in relation to the diameter R and the height T of the cylindrical outer shell 4a of the electrolytic capacitor 4.

  The thermally conductive braided bodies (tubular metal mesh) 20a, 20b and the thermally conductive resin 2c all have elasticity. Therefore, a cylindrical member having a three-layer structure in which these are stacked can be expanded (the inner diameter is expanded) and covered with the cylindrical outer shell 4 a of the electrolytic capacitor 4. Even without using an adhesive means such as an adhesive tape, it is possible to tightly fix to the cylindrical outer shell 4a (aluminum case) of the electrolytic capacitor 4. Thereby, it is easy to automate the manufacture of the heat conducting member 1e and reduce the manufacturing cost, together with the effect of reducing the material cost.

  In the sixth embodiment, each cylindrical body constituting the heat conducting member 1e has a single-layer structure. However, the present invention is not limited to this, and at least one of the cylindrical bodies may be a plurality of layers. Good.

  In the sixth embodiment, the adhesive layer is not provided on the inner surface of the heat conductive member 1e (that is, the inner surface of the heat conductive braid 20a). However, the present invention is not limited to this, and the inner surface of the heat conductive member 1e is provided. An adhesive tape 3 or other adhesive layer may be provided.

  Moreover, in Embodiment 6, the heat conductive member 1e can be manufactured by cutting a cylindrical metal mesh and a heat conductive resin. However, the present invention is not limited to this. In the same manner as in Embodiments 1 to 3, the thermal conductive resin planar body is cut and wound around the cylindrical outer shell 4a of the electrolytic capacitor 4, and the thermal conductive member 1e is made of a metal mesh planar body or thermal conductive material. A plurality of long bodies formed by cutting from a planar body of resin material may be wound around the cylindrical outer shell 4a of the electrolytic capacitor 4 with an adhesive layer (adhesive tape) interposed therebetween.

13 and 14 are perspective views showing the configuration of the heat conducting member 1f according to the seventh embodiment of the present invention. FIG. 15 is a perspective view showing the configuration of the electrolytic capacitor 4 to which the heat conducting member 1f according to the seventh embodiment of the present invention is attached. Other configurations and manufacturing methods are the same as those in the first embodiment, and thus description thereof is omitted.

  In the present embodiment, as shown in FIG. 13, the heat conductive braided body (tubular metal mesh) 20c is folded back as shown by the arrow in the figure to form a bag. And as shown in FIG. 14, the heat conductive member 1f shall be comprised by inserting the heat conductive resin 2d in the bag-shaped heat conductive braided body 20c.

  In the present embodiment, the heat conductive braid 20c is folded back inward. The inner diameter of the thermally conductive braid 20c when not folded is R6, and the inner diameter of the innermost portion of the thermally conductive braid 20c when folded into two layers is R8. R8 is set to R8 ≦ R in relation to the diameter R of the cylindrical outer shell 4a of the electrolytic capacitor 4. On the other hand, the relationship between the width W1 of the folded heat conductive braid 20c and the height T of the cylindrical outer shell 4a of the electrolytic capacitor 4 satisfies W1 ≦ T.

  For the manufacturing method according to the seventh embodiment, referring to the flowchart of FIG. 5 showing the manufacturing method according to the first embodiment, the preparation steps (steps S102 and S106) for preparing the heat conductive member and the heat conductive member 1f are prepared. The content of the attachment process (S108) attached to the electrolytic capacitor 4 is different.

  As a manufacturing method, first, a metal mesh manufactured in advance in a cylindrical shape is cut into a predetermined length 2 × W1. The cut thermally conductive braided body (cylindrical metal mesh) 20c is bent at exactly half the length W1 to form a tubular bag portion. The heat conductive resin 2d is inserted into the cylindrical bag portion, and the heat conductive resin 2d is gripped and laminated on the bent heat conductive braided body (tubular metal mesh) 20c. The inner diameter of the heat conductive resin 2d is R4, similar to the heat conductive resin 2c. The heat conductive resin 2d having the inner diameter R4 is inserted between the two folded layers of the heat conductive braid 20c. Thereby, the heat conductive member 1f provided with the cylindrical three-layer structure is obtained.

  The width of the heat conductive resin 2d is W2, and this W2 is preferably slightly smaller than W1. Thereby, when the heat conductive resin 2d is inserted into the cylindrical bag portion, the position of the edge of the heat conductive braid 20c and the edge of the heat conductive resin 2d can be made to coincide with each other.

  By cooling and using the heat conductive resin 2d on the heat conductive braided body (cylindrical metal mesh) 20c bent as the heat conductive member 1f, cooling of the electrolytic capacitor 4 is further promoted. Further, by adopting a material having a large heat capacity for the second layer of thermally conductive resin 2d that is gripped and laminated, the effect of promoting the heat dispersion of the electrolytic capacitor 4 is achieved.

  According to the present embodiment, the heat conductive braided body (cylindrical metal mesh) 20c and the heat conductive resin 2d have elasticity, and the cylindrical state of these three-layer structures is expanded (the inner diameter is expanded). ), It is sufficient to cover the cylindrical shell 4 a of the electrolytic capacitor 4. Even without using an adhesive means such as an adhesive tape, it is possible to tightly fix to the cylindrical outer shell 4a (aluminum case) of the electrolytic capacitor 4. Thereby, in addition to the automation of the manufacture of the heat conducting member 1f and the reduction of the manufacturing cost, there is an effect of reducing the material cost.

  In the seventh embodiment, the thermally conductive braid 20c is folded once to form a bag shape, but the present invention is not limited to this and may be folded twice or more. In the seventh embodiment, one end side of the heat conductive braided body 20c is inserted into the inside of the other end side to form a bag. However, conversely, it is good also as a bag shape so that one end side may be covered on the outer side of a multi-end side.

  In the seventh embodiment, the adhesive layer is not provided on the inner surface of the heat conductive member 1f (that is, the innermost surface of the heat conductive braided body 20c). However, the present invention is not limited to this, and the most heat conductive member 1f.
