Features.

第6の発明は、第5の発明に係る被接続部品の放熱構造において、上記インパネメンバは、熱伝導性樹脂からなることを特徴とする。   According to a sixth invention, in the heat dissipation structure for a connected part according to the fifth invention, the instrument panel member is made of a heat conductive resin.

第7の発明は、第1〜4のいずれか1つの発明に係る被接続部品の放熱構造において、上記放熱部品は、車体パネルであることを特徴とする。   According to a seventh invention, in the heat dissipation structure for a connected component according to any one of the first to fourth inventions, the heat dissipation component is a vehicle body panel.

第8の発明は、第1〜7のいずれか1つの発明に係る被接続部品の放熱構造において、上記被接続部品は、電装部品であることを特徴とする。   According to an eighth invention, in the heat dissipation structure for a connected component according to any one of the first to seventh inventions, the connected component is an electrical component.

第1の発明によれば、放熱部品と熱伝導体とを、粘性流体の熱伝導性グリースを介して接合したので、固体のガスケットを介して接合した場合に比べて放熱部品と熱伝導体との間隔を狭くしやすい。したがって、放熱性を向上できる。   According to the first invention, since the heat dissipation component and the heat conductor are joined via the heat conductive grease of the viscous fluid, the heat dissipation component and the heat conductor are compared with the case where they are joined via the solid gasket. It is easy to narrow the interval. Therefore, heat dissipation can be improved.

また、放熱部品と熱伝導体とを、粘性流体の熱伝導性グリースを介して接合したので、固体のガスケットを介して接合した場合に比べて放熱部品と熱伝導体との間に空間が形成されにくい。したがって、放熱部品と熱伝導体との間に空間が形成されることによる放熱性の悪化を防止できる。   In addition, since the heat dissipation component and the heat conductor are joined via the heat conductive grease of the viscous fluid, a space is formed between the heat dissipation component and the heat conductor compared to the case of joining via the solid gasket. It is hard to be done. Therefore, it is possible to prevent deterioration of heat dissipation due to the formation of a space between the heat dissipation component and the heat conductor.

また、放熱部品と熱伝導体との接合箇所で凸部が凹部に嵌合しているので、放熱部品と熱伝導体とを平坦面で接合した場合に比べ、車の振動等により熱伝導体が放熱部品に対して大きく移動しないので、接合箇所に介在する熱伝導性グリースが流出し難い。したがって、放熱部品と熱伝導体との間に空間が形成されることによる放熱性の悪化を防止できる。   In addition, since the convex portion is fitted in the concave portion at the joint portion between the heat dissipation component and the heat conductor, the heat conductor is caused by vibration of the car or the like compared to the case where the heat dissipation component and the heat conductor are joined on a flat surface. Does not move greatly with respect to the heat dissipating parts, so that the heat conductive grease intervening at the joint is difficult to flow out. Therefore, it is possible to prevent deterioration of heat dissipation due to the formation of a space between the heat dissipation component and the heat conductor.

また、放熱部品と熱伝導体との接合箇所で凸部が凹部に嵌合しているので、放熱部品と熱伝導体とを平坦面で接合した場合に比べて接合面積が大きくなり、熱伝導体から放熱部品に熱が伝わりやすくなる。したがって、放熱性を向上できる。   In addition, since the convex part fits into the recess at the joint between the heat dissipation component and the heat conductor, the bonding area is larger than when the heat dissipation component and the heat conductor are joined on a flat surface, and the heat conduction Heat is easily transferred from the body to the heat dissipation component. Therefore, heat dissipation can be improved.

第2の発明によれば、熱伝導体が、放熱部品と放熱部品側板部材とで挟持された領域で放熱部品から離間しにくくなり、熱伝導体と放熱部品との接合面積が当該領域の面積分確保されるので、放熱性を向上できる。   According to the second invention, the heat conductor is less likely to be separated from the heat dissipation component in the region sandwiched between the heat dissipation component and the heat dissipation component side plate member, and the bonding area between the heat conductor and the heat dissipation component is the area of the region. Therefore, heat dissipation can be improved.

第3の発明によれば、被接続部品と熱伝導体とを、粘性流体の熱伝導性グリースを介して接合したので、固体のガスケットを介して接合した場合に比べて被接続部品と熱伝導体との間隔を狭くしやすい。したがって、放熱性を向上できる。   According to the third aspect, since the connected component and the heat conductor are joined via the heat conductive grease of the viscous fluid, the connected component and the heat conduction are compared with the case where they are joined via the solid gasket. It is easy to narrow the distance from the body. Therefore, heat dissipation can be improved.

また、被接続部品と熱伝導体とを、粘性流体の熱伝導性グリースを介して接合したので、固体のガスケットを介して接合した場合に比べて被接続部品と熱伝導体との間に空間が形成されにくい。したがって、被接続部品と熱伝導体との間に空間が形成されることによる放熱性の悪化を防止できる。   In addition, since the connected component and the thermal conductor are joined via the thermal conductive grease of the viscous fluid, the space between the connected component and the thermal conductor is smaller than when joined via the solid gasket. Is difficult to form. Accordingly, it is possible to prevent deterioration of heat dissipation due to the formation of a space between the connected component and the heat conductor.

また、被接続部品と熱伝導体との接合箇所で凸状部が凹状部に嵌合しているので、被接続部品と熱伝導体とを平坦面で接合した場合に比べ、車の振動等により熱伝導体が被接続部品に対して大きく移動しないので、接合箇所に介在する熱伝導性グリースが流出し難い。したがって、被接続部品と熱伝導体との間に空間が形成されることによる放熱性の悪化を防止できる。   In addition, since the convex part is fitted into the concave part at the joint between the connected part and the heat conductor, the vibration of the car, etc., compared to the case where the connected part and the heat conductor are joined on a flat surface. As a result, the heat conductor does not move significantly with respect to the connected parts, so that the heat conductive grease intervening at the joining portion hardly flows out. Accordingly, it is possible to prevent deterioration of heat dissipation due to the formation of a space between the connected component and the heat conductor.

また、被接続部品と熱伝導体との接合箇所で凸状部が凹状部に嵌合しているので、被接続部品と熱伝導体とを平坦面で接合した場合に比べて接合面積が大きくなり、被接続部品から熱伝導体に熱が伝わりやすくなる。したがって、放熱性を向上できる。   In addition, since the convex part is fitted into the concave part at the joint between the connected component and the thermal conductor, the joint area is larger than when the connected part and the thermal conductor are joined on a flat surface. Thus, heat is easily transmitted from the connected component to the heat conductor. Therefore, heat dissipation can be improved.

第4の発明によれば、熱伝導体が、被接続部品と被接続部品側板部材とで挟持された領域で被接続部品から離間しにくくなり、熱伝導体と被接続部品との接合面積が当該領域の面積分確保されるので、放熱性を向上できる。   According to the fourth invention, the thermal conductor is less likely to be separated from the connected component in the region sandwiched between the connected component and the connected component side plate member, and the bonding area between the thermal conductor and the connected component is reduced. Since the area of the area is secured, heat dissipation can be improved.

第5の発明によれば、インパネメンバが放熱部品の役割を果たし、放熱部品を別途設ける必要がないので、部品点数及び製造コストを削減できる。   According to the fifth invention, the instrument panel member serves as a heat radiating component, and it is not necessary to separately provide the heat radiating component, so that the number of components and the manufacturing cost can be reduced.

第6の発明によれば、インパネメンバを熱伝導性樹脂で構成したので、インパネメンバの放熱性を確保しつつ、金属で構成した場合に比べ、インパネメンバを軽量化するとともに製造コストを削減できる。   According to the sixth invention, since the instrument panel member is made of a heat conductive resin, the instrument panel member can be reduced in weight and the manufacturing cost can be reduced as compared with the case where the instrument panel member is made of metal while ensuring the heat dissipation of the instrument panel member. .

第7の発明によれば、車体パネルが放熱部品の役割を果たし、放熱部品を別途設ける必要がないので、部品点数及び製造コストを削減できる。   According to the seventh aspect, since the vehicle body panel serves as a heat radiating component and there is no need to separately provide the heat radiating component, the number of components and the manufacturing cost can be reduced.

第8の発明によれば、電装部品の熱が熱伝導体を介して放熱部品から放熱されるので、電装部品に大型のヒートシンクを設ける必要がない。したがって、電装部品の軽量化、小型化、及び低コスト化を実現できる。   According to the eighth aspect of the invention, the heat of the electrical component is radiated from the heat dissipation component via the heat conductor, so there is no need to provide a large heat sink on the electrical component. Therefore, it is possible to reduce the weight, size, and cost of the electrical component.

In addition, a plurality of insertion holes 39 are formed in the vicinity of the first to third groove forming regions R1 to R3 of the instrument panel member 3, as shown in FIG. The instrument panel member 3 is made of a thermally conductive resin. Examples of the thermally conductive resin include polypropylene (PP), graphite, silver, copper, gold, silicon, silicon carbide, beryllia, aluminum nitride, boron nitride, silicon nitride, A heat-conductive powder such as magnesia or alumina, a mixture of fillers, or a carbon fiber reinforced plastic can be used.

そして、上記ヘッドアップディスプレイ装置11の背面部材11bの表面は、長尺帯状の熱伝導体としての熱伝導フィルム41を介してインパネメンバ3の第1の溝部形成領域R1に接続されている。熱伝導フィルム41の長手方向両端部には、一方の面に断面三角形状の複数の凸条部43が長手方向に隣り合ってギザギザ形状をなすように形成された第1及び第2の凸条部形成領域RE1,RE2が設けられている。第1の凸条部形成領域RE1の凸条部43は、インパネメンバ3の第1の溝部形成領域R1の溝部37に嵌合した状態で熱伝導性グリース44を介して接合されている。この状態で、熱伝導フィルム41の凸条部43の突出高さの半分以上がインパネメンバ3の溝部37に入っている。一方、第2の凸条部形成領域RE2の凸条部43は、ヘッドアップディスプレイ装置11の凹条部15に嵌合した状態で熱伝導性グリース44を介して接合されている。この状態で、熱伝導フィルム41の凸条部43の突出高さの半分以上がヘッドアップディスプレイ装置11の凹条部15に入っている。したがって、第1の凸条部形成領域RE1の凸条部43が凸部を構成し、第2の凸条部形成領域RE2の凸条部43が凸状部を構成している。また、熱伝導フィルム41の長手方向両端部には、それぞれ複数のネジ孔45が形成されている。熱伝導フィルム41は、例えば、カーボンで構成され、両端部をプレス加工によりギザギザ形状とした複数枚の熱伝導シートを積層するか又は、複数枚の平坦な熱伝導シートを積層した後にその両端部をプレス加工によりギザギザ形状とすることにより製造される。   And the surface of the back member 11b of the head-up display device 11 is connected to the first groove forming region R1 of the instrument panel member 3 through a heat conductive film 41 as a long belt-like heat conductor. At both ends in the longitudinal direction of the heat conducting film 41, a plurality of ridges 43 having a triangular cross section on one surface are formed adjacent to each other in the longitudinal direction to form a jagged shape. Part formation regions RE1 and RE2 are provided. The ridges 43 of the first ridge formation region RE1 are joined via the heat conductive grease 44 in a state of being fitted to the grooves 37 of the first groove formation region R1 of the instrument panel member 3. In this state, more than half of the protruding height of the protrusion 43 of the heat conductive film 41 is in the groove 37 of the instrument panel member 3. On the other hand, the ridges 43 of the second ridge formation region RE2 are joined via the heat conductive grease 44 in a state of being fitted to the ridges 15 of the head-up display device 11. In this state, more than half of the protruding height of the protruding portion 43 of the heat conductive film 41 is in the recessed portion 15 of the head-up display device 11. Accordingly, the ridges 43 of the first ridge formation region RE1 constitute a projection, and the ridges 43 of the second ridge formation region RE2 constitute a projection. In addition, a plurality of screw holes 45 are formed at both ends in the longitudinal direction of the heat conductive film 41. The heat conductive film 41 is made of, for example, carbon, and a plurality of heat conductive sheets whose both end portions are jagged by press working are laminated, or both end portions thereof are laminated after a plurality of flat heat conductive sheets are laminated. Is manufactured to have a jagged shape by pressing.

そして、熱伝導フィルム41の第1の凸条部形成領域RE1側の端部は、熱伝導フィルム41のネジ孔45、インパネメンバ3の挿通孔39、及びインパネメンバ3の後面部21の前側に設けられるナット47にネジ49を挿通することで、インパネメンバ3に締結されている。一方、熱伝導フィルム41の第2の凸条部形成領域RE2側の端部は、熱伝導フィルム41のネジ孔45、及びヘッドアップディスプレイ装置11の背面部材11bの締結孔(図示せず)にネジ49を挿通することで、ヘッドアップディスプレイ装置11の背面部材11bに締結されている。   And the edge part by the side of the 1st convex part formation area RE1 of the heat conductive film 41 is the screw hole 45 of the heat conductive film 41, the insertion hole 39 of the instrument panel member 3, and the front side of the rear surface part 21 of the instrument panel member 3. The screws 49 are inserted into the nuts 47 that are provided, thereby being fastened to the instrument panel member 3. On the other hand, the end of the heat conductive film 41 on the second ridge forming region RE2 side is a screw hole 45 of the heat conductive film 41 and a fastening hole (not shown) of the back member 11b of the head-up display device 11. By inserting the screw 49, the back member 11b of the head-up display device 11 is fastened.

また、上記カーナビゲーション17の背面部材も、ヘッドアップディスプレイ装置11の背面部材11bと同様に熱伝導フィルム41を介してインパネメンバ3の第2の溝部形成領域R2に接続され、HVAC19の背面部材も、ヘッドアップディスプレイ装置11の背面部材11bと同様に熱伝導フィルム41を介してインパネメンバ3の第3の溝部形成領域R3に接続されている。   Further, the rear member of the car navigation 17 is connected to the second groove forming region R2 of the instrument panel member 3 through the heat conductive film 41 in the same manner as the rear member 11b of the head-up display device 11, and the rear member of the HVAC 19 Similarly to the back member 11 b of the head-up display device 11, it is connected to the third groove forming region R 3 of the instrument panel member 3 through the heat conductive film 41.

したがって、本実施形態1によれば、ヘッドアップディスプレイ装置11、カーナビゲーション17、及びHVAC19の熱が、熱伝導フィルム41を介してインパネメンバ3から放熱されるので、ヘッドアップディスプレイ装置11、カーナビゲーション17、及びHVAC19に大型のヒートシンクを設ける必要がない。したがって、ヘッドアップディスプレイ装置11、カーナビゲーション17、及びHVAC19の軽量化、小型化、及び低コスト化を実現できる。   Therefore, according to the first embodiment, the heat of the head-up display device 11, the car navigation system 17, and the HVAC 19 is radiated from the instrument panel member 3 through the heat conductive film 41, so the head-up display device 11, the car navigation system 17 and the HVAC 19 need not be provided with a large heat sink. Therefore, it is possible to reduce the weight, size, and cost of the head-up display device 11, the car navigation system 17, and the HVAC 19.

また、インパネメンバ3と熱伝導フィルム41とを、粘性流体の熱伝導性グリース44を介して接合したので、固体のガスケットを介して接合した場合に比べてインパネメンバ3と熱伝導フィルム41との間隔を狭くしやすい。したがって、放熱性を向上できる。   Moreover, since the instrument panel member 3 and the heat conductive film 41 are joined via the heat conductive grease 44 of a viscous fluid, the instrument panel member 3 and the heat conductive film 41 are compared with the case where they are joined via a solid gasket. It is easy to narrow the interval. Therefore, heat dissipation can be improved.

また、インパネメンバ3と熱伝導フィルム41とを、粘性流体の熱伝導性グリース44を介して接合したので、固体のガスケットを介して接合した場合に比べ、インパネメンバ3と熱伝導フィルム41との間に空間が形成されにくい。したがって、インパネメンバ3と熱伝導フィルム41との間に空間が形成されることによる放熱性の悪化を防止できる。   Moreover, since the instrument panel member 3 and the heat conductive film 41 are joined via the heat conductive grease 44 of a viscous fluid, the instrument panel member 3 and the heat conductive film 41 are compared with the case where they are joined via a solid gasket. It is difficult to form a space between them. Therefore, it is possible to prevent deterioration of heat dissipation due to the formation of a space between the instrument panel member 3 and the heat conductive film 41.

また、熱伝導フィルム41の凸条部43とインパネメンバ3の溝部37とを接合しているので、インパネメンバ3と熱伝導フィルム41とを平坦面で接合した場合に比べ、車の振動等により熱伝導フィルム41がインパネメンバ3に対して大きく移動しないので、接合箇所に介在する熱伝導性グリース44が流出し難い。したがって、インパネメンバ3と熱伝導フィルム41との間に空間が形成されることによる放熱性の悪化を防止できる。   In addition, since the ridges 43 of the heat conductive film 41 and the groove portions 37 of the instrument panel member 3 are joined, compared to the case where the instrument panel member 3 and the heat conductive film 41 are joined on a flat surface, the vibrations of the vehicle, etc. Since the heat conductive film 41 does not move greatly with respect to the instrument panel member 3, the heat conductive grease 44 interposed at the joining portion is difficult to flow out. Therefore, it is possible to prevent deterioration of heat dissipation due to the formation of a space between the instrument panel member 3 and the heat conductive film 41.

また、熱伝導フィルム41の凸条部43とインパネメンバ3の溝部37とを接合しているので、インパネメンバ3と熱伝導フィルム41とを平坦面で接合した場合に比べて接合面積が大きくなり、熱伝導フィルム41からインパネメンバ3に熱が伝わりやすくなる。したがって、放熱性を向上できる。   In addition, since the protrusions 43 of the heat conduction film 41 and the groove portions 37 of the instrument panel member 3 are joined, the joining area becomes larger than when the instrument panel member 3 and the heat conduction film 41 are joined on a flat surface. Heat is easily transmitted from the heat conductive film 41 to the instrument panel member 3. Therefore, heat dissipation can be improved.

また、ヘッドアップディスプレイ装置11、カーナビゲーション17、及びHVAC19と熱伝導フィルム41とを、粘性流体の熱伝導性グリース44を介して接合したので、固体のガスケットを介して接合した場合に比べてヘッドアップディスプレイ装置11、カーナビゲーション17、及びHVAC19と熱伝導フィルム41との間隔を狭くしやすい。したがって、放熱性を向上できる。   Further, since the head-up display device 11, the car navigation system 17, and the HVAC 19 and the heat conducting film 41 are joined via the thermal conductive grease 44 of a viscous fluid, the head is compared with the case where they are joined via a solid gasket. The intervals between the up-display device 11, the car navigation system 17 and the HVAC 19 and the heat conductive film 41 can be easily reduced. Therefore, heat dissipation can be improved.

また、ヘッドアップディスプレイ装置11、カーナビゲーション17、及びHVAC19と熱伝導フィルム41とを、粘性流体の熱伝導性グリース44を介して接合したので、固体のガスケットを介して接合した場合に比べてヘッドアップディスプレイ装置11、カーナビゲーション17、及びHVAC19と熱伝導フィルム41との間に空間が形成されにくい。したがって、ヘッドアップディスプレイ装置11、カーナビゲーション17、及びHVAC19と熱伝導フィルム41との間に空間が形成されることによる放熱性の悪化を防止できる。   Further, since the head-up display device 11, the car navigation system 17, and the HVAC 19 and the heat conducting film 41 are joined via the thermal conductive grease 44 of a viscous fluid, the head is compared with the case where they are joined via a solid gasket. It is difficult to form a space between the up display device 11, the car navigation system 17 and the HVAC 19 and the heat conductive film 41. Therefore, it is possible to prevent deterioration in heat dissipation due to the space formed between the head-up display device 11, the car navigation system 17, and the HVAC 19 and the heat conductive film 41.

また、ヘッドアップディスプレイ装置11、カーナビゲーション17、及びHVAC19の凹条部15と熱伝導フィルム41の凸条部43とを接合しているので、ヘッドアップディスプレイ装置11、カーナビゲーション17、及びHVAC19と熱伝導フィルム41とを平坦面で接合した場合に比べ、車の振動等により熱伝導フィルム41がヘッドアップディスプレイ装置11、カーナビゲーション17、及びHVAC19に対して大きく移動しないので、接合箇所に介在する熱伝導性グリース44が流出し難い。したがって、ヘッドアップディスプレイ装置11、カーナビゲーション17、及びHVAC19と熱伝導フィルム41との間に空間が形成されることによる放熱性の悪化を防止できる。   Moreover, since the concave strip portion 15 of the head-up display device 11, the car navigation 17 and the HVAC 19 and the convex strip portion 43 of the heat conducting film 41 are joined, the head-up display device 11, the car navigation 17 and the HVAC 19 Compared with the case where the heat conductive film 41 is bonded on a flat surface, the heat conductive film 41 does not move significantly with respect to the head-up display device 11, the car navigation system 17 and the HVAC 19 due to vibrations of the vehicle and the like. It is difficult for the heat conductive grease 44 to flow out. Therefore, it is possible to prevent deterioration in heat dissipation due to the space formed between the head-up display device 11, the car navigation system 17, and the HVAC 19 and the heat conductive film 41.

また、ヘッドアップディスプレイ装置11、カーナビゲーション17、及びHVAC19の凹条部15と熱伝導フィルム41の凸条部43とを接合しているので、ヘッドアップディスプレイ装置11、カーナビゲーション17、及びHVAC19と熱伝導フィルム41とを平坦面で接合した場合に比べて接合面積が大きくなり、ヘッドアップディスプレイ装置11、カーナビゲーション17、及びHVAC19から熱伝導フィルム41に熱が伝わりやすくなる。したがって、放熱性を向上できる。   Moreover, since the concave strip portion 15 of the head-up display device 11, the car navigation 17 and the HVAC 19 and the convex strip portion 43 of the heat conducting film 41 are joined, the head-up display device 11, the car navigation 17 and the HVAC 19 Compared with the case where the heat conductive film 41 is bonded on a flat surface, the bonding area is increased, and heat is easily transferred from the head-up display device 11, the car navigation 17, and the HVAC 19 to the heat conductive film 41. Therefore, heat dissipation can be improved.

また、インパネメンバ3が放熱部品の役割を果たし、放熱部品を別途設ける必要がないので、部品点数及び製造コストを削減できる。   Further, since the instrument panel member 3 serves as a heat radiating component and it is not necessary to provide a heat radiating component separately, the number of components and the manufacturing cost can be reduced.

また、インパネメンバ3を熱伝導性樹脂で構成したので、インパネメンバ3の放熱性を確保しつつ、金属で構成した場合に比べ、インパネメンバ3を軽量化するとともに製造コストを削減できる。   Further, since the instrument panel member 3 is made of a heat conductive resin, the instrument panel member 3 can be reduced in weight and the manufacturing cost can be reduced as compared with the case where the instrument panel member 3 is made of metal while ensuring the heat dissipation of the instrument panel member 3.

その他の構成は実施形態1と同じであるので、同一の構成箇所には同一の符号を付してその詳細な説明を省略する。   Since the other configuration is the same as that of the first embodiment, the same components are denoted by the same reference numerals, and detailed description thereof is omitted.

したがって、本実施形態2によれば、熱伝導フィルム41が、インパネメンバ3と第1板部材53とで挟持された領域でインパネメンバ3から離間しにくくなり、インパネメンバ3と熱伝導フィルム41との接合面積が当該領域の面積分確保されるので、放熱性を向上できる。   Therefore, according to the second embodiment, the heat conductive film 41 is hardly separated from the instrument panel member 3 in the region sandwiched between the instrument panel member 3 and the first plate member 53, and the instrument panel member 3 and the heat conductive film 41 Therefore, the heat dissipation can be improved.

また、熱伝導フィルム41が、ヘッドアップディスプレイ装置11の背面部材11bと第2板部材55とで挟持された領域でヘッドアップディスプレイ装置11から離間しにくくなり、熱伝導フィルム41とヘッドアップディスプレイ装置11との接合面積が当該領域の面積分確保されるので、放熱性を向上できる。また、熱伝導フィルム41がカーナビゲーション17と第2板部材55とで挟持された箇所、熱伝導フィルム41がHVAC19と第2板部材55とで挟持された箇所においても、同様の効果が得られる。   In addition, the heat conductive film 41 is less likely to be separated from the head up display device 11 in the region sandwiched between the back member 11b and the second plate member 55 of the head up display device 11, and the heat conductive film 41 and the head up display device. 11 is secured by the area of the region, so that heat dissipation can be improved.
