本発明は、熱伝導部材およびそれを備えるバッテリーに関する。 The present invention relates to a heat conductive member and a battery including the heat conductive member.

複数のセルを接続したバッテリーは、自動車、船舶、航空機などの電力供給に多用されている。自動車を例に挙げると、ガソリンあるいは軽油を燃料としている従来型の自動車は、モータとエンジンとを動力に併用するタイプの自動車、エンジンとモータとを搭載しているがエンジンをバッテリーの充電のみに使用してモータのみを動力に用いるタイプの自動車、およびエンジンを搭載せずにバッテリーに接続されるモータのみを動力に用いるタイプの自動車へと変わってきている。 Batteries connecting multiple cells are often used to supply electric power to automobiles, ships, aircraft, and the like. Taking an automobile as an example, a conventional automobile that uses gasoline or light oil as fuel is equipped with a type of automobile that uses a motor and an engine as power, and an engine and a motor, but the engine is used only for charging the battery. There is a change to a type of automobile that uses only a motor for power, and a type of automobile that uses only a motor connected to a battery without an engine.

バッテリーに搭載されるセルは、充電と放電とを繰り返し可能な二次電池である。セルは、充電時および放電時に発熱し、６０℃以上になると、充電および放電の各機能が低下しやすい。このため、セルからの除熱、より具体的には、充電若しくは放電中のセルから、セルを搭載している水冷若しくは空冷タイプの筐体へと効果的に熱を移動させることが求められる。 The cell mounted on the battery is a secondary battery that can be repeatedly charged and discharged. The cell generates heat during charging and discharging, and when the temperature rises above 60 ° C., the charging and discharging functions tend to deteriorate. Therefore, it is required to effectively transfer heat from the cell, more specifically, from the cell being charged or discharged to the water-cooled or air-cooled type housing on which the cell is mounted.

セルからの放熱を高めるバッテリーとして、例えば、セルと筐体との間に樹脂層を介在させたバッテリーが知られている（特許文献１を参照）。樹脂層の中には、より好ましくは、熱伝導性の高いフィラー（アルミナあるいはグラファイト製のフィラー）が分散されている。これにより、セルからの熱は、セルと筐体に密着している樹脂層を経由して、筐体へと速やかに移動できる。 As a battery that enhances heat dissipation from the cell, for example, a battery in which a resin layer is interposed between the cell and the housing is known (see Patent Document 1). More preferably, a filler having high thermal conductivity (a filler made of alumina or graphite) is dispersed in the resin layer. As a result, the heat from the cell can be quickly transferred to the housing via the resin layer that is in close contact with the cell and the housing.

特表２０１９－５０８８７１Special table 2019-508781

しかし、上記公知のバッテリーは、セルと筐体との間に樹脂層を形成する労力、樹脂層を交換する労力を要するため、バッテリーのコストアップを招く。また、樹脂層に熱伝導性の高いフィラーを分散させても、樹脂の比率よりもフィラーの体積比率を高めることが難しいため、熱伝導性を高めるには限界がある。 However, the above-mentioned known battery requires labor for forming a resin layer between a cell and a housing and labor for replacing the resin layer, which leads to an increase in battery cost. Further, even if a filler having high thermal conductivity is dispersed in the resin layer, it is difficult to increase the volume ratio of the filler more than the ratio of the resin, so that there is a limit to increasing the thermal conductivity.

このような課題を解決するために、本出願人の発明者は、先に、セルと筐体の間、およびセルとセルとの間に、樹脂若しくはゴムの外側にグラファイトに代表されるシートを備えた二層構造の熱伝導部材を配置する方法を考えた。かかる熱伝導部材は、筐体とセルとの間にセットしやすく、また交換も容易である。さらには、シートは樹脂よりも熱伝導性が高いため、セルから筐体へと速やかな熱伝導を実現できる。このような熱伝導部材には、セルから筐体へのさらなる高熱伝導を実現することが求められている。 In order to solve such a problem, the inventor of the present applicant first puts a sheet typified by graphite on the outside of resin or rubber between the cell and the housing and between the cell and the cell. We considered a method of arranging the provided two-layer structure heat conductive member. The heat conductive member is easy to set between the housing and the cell, and is easy to replace. Furthermore, since the sheet has higher thermal conductivity than the resin, rapid thermal conduction can be realized from the cell to the housing. Such a heat conductive member is required to realize higher heat conduction from the cell to the housing.

本発明は、セルと筐体との間に容易に配置でき、容易に交換でき、かつセルから筐体へのより高い熱伝導を実現可能な熱伝導部材、およびそれを備えるバッテリーを提供することを目的とする。 INDUSTRIAL APPLICABILITY The present invention provides a heat conductive member that can be easily placed between a cell and a housing, is easily replaced, and can realize higher heat conduction from the cell to the housing, and a battery including the same.

第１実施形態に係る熱伝導部材１は、複数（すなわち２以上）の長尺状の部材１０を、長尺状の部材１０の長さ方向（Ｙ方向）と直交する幅方向（Ｘ方向）に並べて固定している。この実施形態では、長尺状の部材１０の数は、３２本であるが、２本以上であれば、３２本に限定されない。熱伝導部材１は、好ましくは、隣り合う長尺状の部材１０同士の間に隙間１４を備えるように構成されている。隙間１４は、長尺状の部材１０が幅方向に伸びるように変形容易にするのに寄与している。ただし、隙間１４は、全ての隣り合う長尺状の部材１０同士の間に存在していなくとも良い。長尺状の部材１０は、熱伝導シート１１を外殻として、当該外殻の内部に空間（中空部ともいう）１５を備える。熱伝導シート１１の形態、材料等については、熱伝導シート１７，１８にも同様に適用される。以後、同様である。空間１５は、好ましくは、長尺状の部材１０の長さ方向に貫通する領域であるが、当該長さ方向の一方を閉じた細長いカップ状の領域でも良い。空間１５は、長尺状の部材１０を、その厚さ方向につぶれやすくするのに寄与する限り、その形態に制約はない。長尺状の部材１０の長さ方向から見た面は、この実施形態では、四角形である。ただし、長尺状の部材１０の長さ方向から見た面は、五角以上の「多角形」、あるいは後述の実施形態で説明する「長円形」（「オーバル形状」ともいう）であっても良い。多角形としては、特に、偶数の角を有するものが好ましく、四角形、六角形または八角形がさらに好ましい。複数の長尺状の部材１０は、長尺状の部材１０の平面若しくは最も平面に近い面が幅方向（Ｘ方向）に沿うように並べられている。複数の長尺状の部材１０は、長さ方向（Ｙ方向）の少なくとも両端側にて、幅方向（Ｘ方向）に沿う固定シート２１，２２によって固定されている。ここで、固定シート２１，２２を固定する「両端側」とは、長尺状の部材１０の正確な両端に限定されず、長尺状の部材１０の長さ方向中央よりも端部に近い位置を意味する。 The heat conductive member 1 according to the first embodiment has a plurality of (that is, two or more) long members 10 in a width direction (X direction) orthogonal to the length direction (Y direction) of the long members 10. It is fixed side by side. In this embodiment, the number of the elongated members 10 is 32, but the number is not limited to 32 as long as it is two or more. The heat conductive member 1 is preferably configured to have a gap 14 between adjacent elongated members 10. The gap 14 contributes to facilitating the deformation of the elongated member 10 so as to extend in the width direction. However, the gap 14 does not have to exist between all the adjacent elongated members 10. The elongated member 10 has a heat conductive sheet 11 as an outer shell, and has a space (also referred to as a hollow portion) 15 inside the outer shell. The form, material and the like of the heat conductive sheet 11 are similarly applied to the heat conductive sheets 17 and 18. The same applies thereafter. The space 15 is preferably a region penetrating the elongated member 10 in the length direction, but may be an elongated cup-shaped region in which one of the length directions is closed. The space 15 is not limited in its form as long as it contributes to making the elongated member 10 easily crushed in the thickness direction thereof. The surface of the elongated member 10 seen from the length direction is a quadrangle in this embodiment. However, the surface of the elongated member 10 seen from the length direction may be a "polygon" having a pentagon or more, or an "oval" (also referred to as an "oval shape") described in the embodiment described later. good. As the polygon, a polygon having an even number of angles is particularly preferable, and a quadrangle, a hexagon or an octagon is further preferable. The plurality of elongated members 10 are arranged so that the plane or the surface closest to the plane of the elongated member 10 is arranged along the width direction (X direction). The plurality of elongated members 10 are fixed by fixing sheets 21 and 22 along the width direction (X direction) at least on both ends in the length direction (Y direction). Here, the "both ends" for fixing the fixing sheets 21 and 22 are not limited to the exact ends of the elongated member 10, and are closer to the ends than the center in the length direction of the elongated member 10. Means position.

長尺状の部材１０は、その開口面を四角形とし、かつ熱伝導シート１１を、その内部に空間１５を形成するように筒状に巻いた筒状部材である。長尺状の部材１０は、その厚さ方向（Ｚ方向）の面を平面とするように、長尺状の部材１０の幅方向（Ｘ方向）に並べられている。このため、熱伝導部材１を、長尺状の部材１０の厚さ方向（Ｚ方向）から熱源と冷却源（熱を逃がす部分であって、例えば、後述の「筐体」をいう。）にて挟持した際に、熱伝導部材１を構成する長尺状の部材１０は熱源および／または冷却源と面接触しやすくなる。この結果、熱源から熱伝導部材１を経て冷却源へと熱を伝えやすくなる。冷却源は、例えば、後述の冷却剤５５、あるいは筐体５１（特に、底部５３）に相当する。熱伝導シート１１は、導電性に優れるか否かは問わない。熱伝導シート１１の熱伝導率は、好ましくは１０Ｗ／ｍＫ以上である。この実施形態では、熱伝導シート１１は、熱伝導性を有するいかなる材料で構成可能である。熱伝導シート１１は、好ましくは、グラファイト製若しくは金属製であり、熱伝導性と導電性に優れる材料から成る。熱伝導シート１１は、湾曲性（若しくは屈曲性）に優れるシートであるのが好ましく、その厚さに制約はないが、０．０２～３ｍｍが好ましく、０．０３～０．５ｍｍがより好ましい。ただし、熱伝導シート１１の熱伝導率は、その厚さが増加するほど低下するため、シートの強度、可撓性および熱伝導性を総合的に考慮して、その厚さを決定するのが好ましい。 The elongated member 10 is a tubular member having a quadrangular opening surface and a heat conductive sheet 11 wound in a cylindrical shape so as to form a space 15 inside the member 10. The elongated members 10 are arranged in the width direction (X direction) of the elongated members 10 so that the surface in the thickness direction (Z direction) is a flat surface. Therefore, the heat conductive member 1 is used as a heat source and a cooling source (a portion for releasing heat, for example, referred to as a "housing" described later) from the thickness direction (Z direction) of the elongated member 10. When sandwiched between them, the elongated member 10 constituting the heat conductive member 1 easily comes into surface contact with the heat source and / or the cooling source. As a result, it becomes easy to transfer heat from the heat source to the cooling source via the heat conductive member 1. The cooling source corresponds to, for example, the coolant 55 described later or the housing 51 (particularly, the bottom 53). It does not matter whether the heat conductive sheet 11 is excellent in conductivity or not. The thermal conductivity of the heat conductive sheet 11 is preferably 10 W / mK or more. In this embodiment, the heat conductive sheet 11 can be made of any material having heat conductivity. The heat conductive sheet 11 is preferably made of graphite or metal, and is made of a material having excellent heat conductivity and conductivity. The heat conductive sheet 11 is preferably a sheet having excellent bendability (or flexibility), and the thickness thereof is not limited, but 0.02 to 3 mm is preferable, and 0.03 to 0.5 mm is more preferable. However, since the thermal conductivity of the heat conductive sheet 11 decreases as the thickness increases, it is necessary to comprehensively consider the strength, flexibility and heat conductivity of the sheet to determine the thickness. preferable.

熱伝導シート１１は、この実施形態では、固定シート２１，２２と固定されていない部位、すなわち、筒状部材を挟んで固定シート２１，２２の反対側の面に、長尺状の部材１０の長さ方向に向かって進行するスリット１２を備える。この実施形態では、スリット１２は、長尺状の部材１０の長さ方向の全長に亘って形成されているが、全長でなくとも良い。スリット１２は、長尺状の部材１０をその厚さ方向（Ｚ方向）から圧縮された際に、熱伝導シート１１が長尺状の部材１０の幅方向（Ｘ方向）に広がりやすくするのに寄与する。 In this embodiment, the heat conductive sheet 11 is formed on a portion that is not fixed to the fixed sheets 21 and 22, that is, on the opposite surface of the fixed sheets 21 and 22 with the tubular member interposed therebetween. A slit 12 that advances in the length direction is provided. In this embodiment, the slit 12 is formed over the entire length of the elongated member 10 in the length direction, but it does not have to be the total length. The slit 12 makes it easy for the heat conductive sheet 11 to spread in the width direction (X direction) of the long member 10 when the long member 10 is compressed from the thickness direction (Z direction). Contribute.

熱伝導シート１１は、好ましくは、グラファイトを含めて、９０質量％以上を炭素から構成されるシートである。例えば、熱伝導シート１１に、樹脂を焼成して成るグラファイト製のフィルムを用いることもできる。ただし、熱伝導シート１１は、炭素と樹脂とを含むシートであっても良い。その場合、樹脂は、合成繊維でも良く、その場合には、樹脂として好適にはアラミド繊維を用いることができる。なお、本願でいう「炭素」は、グラファイト、グラファイトより結晶性の低いカーボンブラック、ダイヤモンド、ダイヤモンドに近い構造を持つダイヤモンドライクカーボン等の炭素（元素記号：Ｃ）から成る如何なる構造のものも含むように広義に解釈される。熱伝導シート１１は、樹脂に、グラファイト繊維やカーボン粒子を配合分散した材料を硬化させた薄いシートとすることができる。熱伝導シート１１は、メッシュ状に編んだカーボンファイバーであっても良く、さらには混紡してあっても混編みしてあっても良い。なお、グラファイト繊維、カーボン粒子あるいはカーボンファイバーといった各種フィラーも、すべて、炭素の概念に含まれる。 The heat conductive sheet 11 is preferably a sheet composed of 90% by mass or more of carbon, including graphite. For example, a graphite film formed by firing a resin can also be used for the heat conductive sheet 11. However, the heat conductive sheet 11 may be a sheet containing carbon and a resin. In that case, the resin may be synthetic fiber, and in that case, aramid fiber can be preferably used as the resin. The term "carbon" as used in the present application includes graphite, carbon black having a lower crystalline property than graphite, diamond, and any structure composed of carbon (element symbol: C) such as diamond-like carbon having a structure similar to diamond. Is interpreted in a broad sense. The heat conductive sheet 11 can be a thin sheet obtained by curing a material in which graphite fibers and carbon particles are mixed and dispersed in a resin. The heat conductive sheet 11 may be carbon fiber knitted in a mesh shape, and may be blended or knitted. In addition, various fillers such as graphite fiber, carbon particles or carbon fiber are all included in the concept of carbon.

熱伝導シート１１を炭素と樹脂とを備えるシートとする場合には、当該樹脂が熱伝導シート１１の全質量に対して５０質量％未満であるのが好ましい。樹脂としては、例えば、熱可塑性樹脂を好適に使用できる。熱可塑性樹脂としては、熱源からの熱を伝導する際に溶融しない程度の高融点を備える樹脂が好ましく、例えば、ポリフェニレンスルフィド（ＰＰＳ）、ポリエーテルエーテルケトン（ＰＥＥＫ）、ポリアミドイミド（ＰＡＩ）、芳香族ポリアミド（アラミド繊維）等を好適に挙げることができる。樹脂は、熱伝導シート１１の成形前の状態において、炭素フィラーの隙間に、例えば粒子状あるいは繊維状に分散している。熱伝導シート１１は、炭素フィラー、樹脂の他、熱伝導をより高めるためのフィラーとして、ＡｌＮあるいはダイヤモンドを分散していても良い。また、樹脂に代えて、樹脂よりも柔軟なエラストマーを用いても良い。熱伝導シート１１は、また、上述のような炭素に代えて若しくは炭素と共に、金属および／またはセラミックスを含むシートとすることができる。金属としては、アルミニウム、銅、それらの内の少なくとも１つを含む合金などの熱伝導性の比較的高いものを選択できる。 When the heat conductive sheet 11 is a sheet including carbon and a resin, the resin is preferably less than 50% by mass with respect to the total mass of the heat conductive sheet 11. As the resin, for example, a thermoplastic resin can be preferably used. As the thermoplastic resin, a resin having a high melting point that does not melt when conducting heat from a heat source is preferable, and for example, polyphenylene sulfide (PPS), polyetheretherketone (PEEK), polyamideimide (PAI), and fragrance. Group polyamide (aramid fiber) and the like can be preferably mentioned. The resin is dispersed in the gaps between the carbon fillers, for example, in the form of particles or fibers in the state before molding of the heat conductive sheet 11. In addition to the carbon filler and the resin, the heat conductive sheet 11 may be dispersed with AlN or diamond as a filler for further enhancing the heat conduction. Further, instead of the resin, an elastomer that is more flexible than the resin may be used. The heat conductive sheet 11 can also be a sheet containing metals and / or ceramics in place of or with carbon as described above. As the metal, a metal having a relatively high thermal conductivity such as aluminum, copper, and an alloy containing at least one of them can be selected.

固定シート２１，２２は、好ましくは、接着層１６を介して、長尺状の部材１０に固定されている。また、固定シート２１，２２は、好ましくは、グラファイト製若しくは金属を含む導電性のシートである。固定シート２１，２２として、グラファイト製の繊維若しくは導電性に優れた金属製の繊維によってなるシートを用いても良い。固定シート２１，２２は、好ましくは、少なくとも、その長さ方向（Ｘ方向）に伸縮可能なシートである。長尺状の部材１０がその厚さ方向（Ｚ方向）から圧縮を受けて、その幅方向（Ｘ方向）に伸びた際に、固定シート２１，２２も追従して伸びることを可能にするためである。固定シート２１，２２は、熱伝導シート１１の上述材料の選択肢と同様の材料から構成されていても良い。接着層１６は、導電性に優れるフィラーを含む層であるのが好ましい。しかし、接着層１６の成分は、上述のフィラーを含むものに限定されない。 The fixing sheets 21 and 22 are preferably fixed to the elongated member 10 via the adhesive layer 16. Further, the fixed sheets 21 and 22 are preferably conductive sheets made of graphite or containing metal. As the fixing sheets 21 and 22, a sheet made of graphite fibers or metal fibers having excellent conductivity may be used. The fixed sheets 21 and 22 are preferably at least a sheet that can be expanded and contracted in the length direction (X direction) thereof. To enable the fixed sheets 21 and 22 to follow and extend when the elongated member 10 is compressed from its thickness direction (Z direction) and extends in its width direction (X direction). Is. The fixed sheets 21 and 22 may be made of the same material as the above-mentioned material options of the heat conductive sheet 11. The adhesive layer 16 is preferably a layer containing a filler having excellent conductivity. However, the components of the adhesive layer 16 are not limited to those containing the above-mentioned filler.

固定シート２１，２２は、好ましくは、熱伝導部材１の長さ方向（長尺状の部材１０の幅方向：Ｘ方向）から外に突出している。この実施形態では、固定シート２１は、熱伝導部材１の長さ方向両側に突出した突出部２１ａ，２１ａを備える。同様に、固定シート２２も、また、熱伝導部材１の長さ方向両側に突出した突出部２２ａ，２２ａを備える。ただし、突出部２１ａ，２２ａは、Ｘ方向の両側の内のいずれか一方に存在していても良い。突出部２１ａ，２２ａは、熱伝導部材１を後述のバッテリー５０内にセットする際、熱伝導部材１の正確な配置位置を決めるのに寄与する。 The fixed sheets 21 and 22 preferably project outward from the length direction of the heat conductive member 1 (width direction of the elongated member 10: X direction). In this embodiment, the fixed sheet 21 includes protrusions 21a and 21a protruding from both sides of the heat conductive member 1 in the length direction. Similarly, the fixed sheet 22 also includes protrusions 22a, 22a protruding from both sides of the heat conductive member 1 in the length direction. However, the protrusions 21a and 22a may be present on either side of both sides in the X direction. The protrusions 21a and 22a contribute to determining the accurate arrangement position of the heat conductive member 1 when the heat conductive member 1 is set in the battery 50 described later.

固定シート２１，２２は、長尺状の部材１０の少なくとも両端側にて、熱伝導部材１と固定されているのが好ましい。この結果、熱伝導部材１の平面視による形状（Ｚ方向から見た形状）を四角形に保持しやすい。したがって、熱伝導部材１は、熱源からの熱伝導をより高くでき、かつバッテリーなどの放熱を必要とする場所にセットしやすくなる。また、固定シート２１，２２は、好ましくは、長尺状の部材１０の長さ方向の少なくとも両端側に固定され、かつ幅（長尺状の部材１０の長さ方向の距離）を小さくした形態である。固定シート２１，２２と熱伝導シート１１との間に接着層が介在する領域が大きくなると、熱源から熱伝導部材１を介して冷却源に熱が伝わるのが妨げられる可能性があるからである。一方、固定シート２１，２２の幅を過度に狭くすると、熱伝導部材１の四角形の形状を保持しにくくなる。したがって、熱伝導部材１の熱伝導性と四角形の形状保持を両方維持できるような固定シート２１，２２の幅を選択するのが好ましい。 The fixing sheets 21 and 22 are preferably fixed to the heat conductive member 1 at least on both ends of the elongated member 10. As a result, it is easy to hold the shape of the heat conductive member 1 in a plan view (shape seen from the Z direction) in a quadrangle. Therefore, the heat conduction member 1 can have higher heat conduction from the heat source, and can be easily set in a place such as a battery where heat dissipation is required. Further, the fixed sheets 21 and 22 are preferably fixed to at least both ends in the length direction of the elongated member 10 and have a reduced width (distance in the length direction of the elongated member 10). Is. This is because if the region where the adhesive layer is interposed between the fixed sheets 21 and 22 and the heat conductive sheet 11 becomes large, heat transfer from the heat source to the cooling source via the heat conductive member 1 may be hindered. .. On the other hand, if the widths of the fixed sheets 21 and 22 are excessively narrowed, it becomes difficult to maintain the rectangular shape of the heat conductive member 1. Therefore, it is preferable to select the width of the fixed sheets 21 and 22 so as to maintain both the thermal conductivity of the heat conductive member 1 and the shape retention of the quadrangle.

固定シート２１，２２は、この実施形態では、熱伝導部材１の最も広い面（Ｚ方向にある２つの面）の片面に備えられている。固定シート２１，２２をＺ方向の両側の面に備え、あるいは片側の面に固定シート２１を別の片側の面に固定シート２２を備えても良い。ただし、固定シート２１，２２を上記両側の面に固定すると、熱伝導部材１の総厚が増す。このため、固定シート２１，２２をともに熱伝導部材１の片側の面に備える方がより好ましい。 In this embodiment, the fixing sheets 21 and 22 are provided on one side of the widest surface (two surfaces in the Z direction) of the heat conductive member 1. The fixing sheets 21 and 22 may be provided on both sides in the Z direction, or the fixing sheet 21 may be provided on one side and the fixing sheet 22 may be provided on the other side. However, if the fixing sheets 21 and 22 are fixed to the surfaces on both sides, the total thickness of the heat conductive member 1 increases. Therefore, it is more preferable to provide both the fixing sheets 21 and 22 on one surface of the heat conductive member 1.

第１変形例に係る熱伝導部材１ａは、複数の固定シート（ここでは、固定シート２１と固定シート２２）に挟まれた領域に、別の固定シート２３（第３固定シート２３）を備える。第３固定シート２３は、長尺状の部材１０をその幅方向（Ｘ方向）に並べる方向に沿って熱伝導部材１ａに固定されている。第３固定シート２３を熱伝導部材１ａに固定している点以外、熱伝導部材１ａの構成は、先に説明した熱伝導部材１の構成と同様である。第３固定シート２３によって、複数の長尺状の部材１０の長さ方向中央領域を固定すると、熱伝導部材１ａの形状をより保持しやすくなる。第３固定シート２３の幅は、長尺状の部材１０と、熱源および／または冷却源との間における熱伝導を低減しないように、固定シート２１，２２の各幅よりも狭い方が好ましい。第３固定シート２３は、１枚または２枚以上でも良い。第３固定シート２３は、長尺状の部材１０の幅方向に突出した突出部（突出部２１ａ，２２ａに相当する部分）を備えても良い。当該突出部は、熱伝導部材１ａを後述のバッテリー５０内にセットする際、熱伝導部材１ａの正確な配置位置を決めるのに寄与する。 The heat conductive member 1a according to the first modification includes another fixed sheet 23 (third fixed sheet 23) in a region sandwiched between a plurality of fixed sheets (here, the fixed sheet 21 and the fixed sheet 22). The third fixing sheet 23 is fixed to the heat conductive member 1a along the direction in which the elongated members 10 are arranged in the width direction (X direction). The configuration of the heat conductive member 1a is the same as the configuration of the heat conductive member 1 described above, except that the third fixing sheet 23 is fixed to the heat conductive member 1a. When the central region in the length direction of the plurality of elongated members 10 is fixed by the third fixing sheet 23, it becomes easier to maintain the shape of the heat conductive member 1a. The width of the third fixed sheet 23 is preferably narrower than each width of the fixed sheets 21 and 22 so as not to reduce heat conduction between the elongated member 10 and the heat source and / or the cooling source. The third fixed sheet 23 may be one or two or more. The third fixing sheet 23 may include a protruding portion (a portion corresponding to the protruding portions 21a and 22a) protruding in the width direction of the elongated member 10. The protruding portion contributes to determining an accurate arrangement position of the heat conductive member 1a when the heat conductive member 1a is set in the battery 50 described later.

第２変形例に係る熱伝導部材１ｂは、複数の固定シート２１，２２の内、長尺状の部材１０の長さ方向の片側に固定されている固定シート（第２変形例の説明においてのみ、「第１固定シート」という）２１の幅を、当該長さ方向の別の側に固定されている固定シート（第２変形例の説明においてのみ、「第２固定シート」という）２２の幅より広くしている。かかる構成以外は、先に説明した熱伝導部材１の構成と同様である。第１固定シート２１によって複数の長尺状の部材１０を確実に固定できれば、第２固定シート２２の幅を第１固定シート２１の幅より狭くしても、熱伝導部材１ｂの形状を保持できる。また、第２固定シート２２の幅をより小さくすることにより、長尺状の部材１０と、熱源および／または冷却源との間における熱伝導を高めることができる。 The heat conductive member 1b according to the second modification is a fixed sheet fixed to one side of a plurality of fixed sheets 21 and 22 in the length direction of the elongated member 10 (only in the description of the second modification). , "First fixed sheet") 21 is fixed to another side in the length direction (referred to as "second fixed sheet" only in the description of the second modification) 22 width. It's wider. Other than this configuration, it is the same as the configuration of the heat conductive member 1 described above. If the plurality of elongated members 10 can be securely fixed by the first fixing sheet 21, the shape of the heat conductive member 1b can be maintained even if the width of the second fixing sheet 22 is narrower than the width of the first fixing sheet 21. .. Further, by making the width of the second fixed sheet 22 smaller, it is possible to increase the heat conduction between the elongated member 10 and the heat source and / or the cooling source.

第３変形例に係る熱伝導部材１ｃは、複数の固定シート（ここでは、固定シート２１と固定シート２２）に挟まれた領域に、固定シート２１と固定シート２２とを接続する別の固定シート２４（第３固定シート２４）を備える。第３固定シート２４は、前述の第３固定シート２３と異なり、固定シート２１と固定シート２２とを連結するシートであり、好ましくは、長尺状の部材１０の長さ方向に沿って配置されている。第３固定シート２４を熱伝導部材１ｃに固定している点以外、熱伝導部材１ｃの構成は、先に説明した熱伝導部材１の構成と同様である。第３固定シート２４によって、複数の長尺状の部材１０の長さ方向中央領域を固定すると、熱伝導部材１ｃの形状をより保持しやすくなる。第３固定シート２４の幅は、長尺状の部材１０と、熱源および／または冷却源との間における熱伝導を低減しないように、固定シート２１，２２の各幅よりも狭い方が好ましい。第３固定シート２４は、１枚または２枚以上でも良い。第３固定シート２４は、長尺状の部材１０の長さ方向に突出した突出部（突出部２１ａ，２２ａに相当する部分）を備えても良い。当該突出部は、熱伝導部材１ｃを後述のバッテリー５０内にセットする際、熱伝導部材１ｃの正確な配置位置を決めるのに寄与する。 The heat conductive member 1c according to the third modification is another fixed sheet that connects the fixed sheet 21 and the fixed sheet 22 in a region sandwiched between a plurality of fixed sheets (here, the fixed sheet 21 and the fixed sheet 22). 24 (third fixed sheet 24) is provided. Unlike the above-mentioned third fixed sheet 23, the third fixed sheet 24 is a sheet that connects the fixed sheet 21 and the fixed sheet 22, and is preferably arranged along the length direction of the elongated member 10. ing. The configuration of the heat conductive member 1c is the same as the configuration of the heat conductive member 1 described above, except that the third fixing sheet 24 is fixed to the heat conductive member 1c. When the central region in the length direction of the plurality of elongated members 10 is fixed by the third fixing sheet 24, it becomes easier to maintain the shape of the heat conductive member 1c. The width of the third fixed sheet 24 is preferably narrower than the width of each of the fixed sheets 21 and 22 so as not to reduce heat conduction between the elongated member 10 and the heat source and / or the cooling source. The third fixed sheet 24 may be one or two or more. The third fixing sheet 24 may include a protruding portion (a portion corresponding to the protruding portions 21a and 22a) protruding in the length direction of the elongated member 10. The protruding portion contributes to determining an accurate arrangement position of the heat conductive member 1c when the heat conductive member 1c is set in the battery 50 described later.

第４変形例に係る熱伝導部材１ｄは、熱伝導部材１における１枚の固定シート２１を、４枚の短い固定シート２１に代用した点で、熱伝導部材１と異なる。４枚の固定シート２１は、分離していても、長尺状の部材１０の幅方向（Ｘ方向）に一直線に並んでいる。ただし、４枚の固定シート２１は、一直線に並んでいなくとも良い。さらには、固定シート２１の数は、４枚に限定されず、２枚以上であれば制約はない。このように、熱伝導部材１の固定シート２１に比べて短い固定シート２１を分離して用いると、固定シート２１の熱伝導性が熱伝導シート１１の熱伝導性より低い場合であっても、熱源からの冷却源への熱伝導を妨げるリスクが低くなる。なお、固定シート２１に代えて、あるいは固定シート２１と共に、熱伝導部材１の１枚の固定シート２２を、上記の２枚以上の短い固定シート２１と同様に短くし、長尺状の部材１０に固定しても良い。 The heat conductive member 1d according to the fourth modification is different from the heat conductive member 1 in that one fixed sheet 21 in the heat conductive member 1 is replaced with four short fixed sheets 21. Even if the four fixed sheets 21 are separated, they are aligned in a straight line in the width direction (X direction) of the elongated member 10. However, the four fixed sheets 21 do not have to be aligned. Furthermore, the number of fixed sheets 21 is not limited to four, and there is no restriction as long as it is two or more. As described above, when the fixed sheet 21 which is shorter than the fixed sheet 21 of the heat conductive member 1 is separated and used, even when the heat conductivity of the fixed sheet 21 is lower than the heat conductivity of the heat conductive sheet 11. The risk of interfering with heat conduction from the heat source to the cooling source is reduced. In addition, instead of the fixed sheet 21, or together with the fixed sheet 21, one fixed sheet 22 of the heat conductive member 1 is shortened in the same manner as the above two or more short fixed sheets 21, and the long member 10 is formed. It may be fixed to.

第５変形例に係る熱伝導部材１ｅは、熱伝導部材１ｅを構成している一部の長尺状の部材１０を当該一部以外の長尺状の部材１０より長尺方向に長くしており、固定シート２１を、当該一部の長尺状の部材１０に固定している。熱伝導部材１ｅは、当該熱伝導部材１ｅを構成している複数の長尺状の部材１０の内の一部（図中、「ｘ」で示す長尺状の部材１０）をＹ方向に長くして、当該一部に固定シート２１を固定している点で、熱伝導部材１と異なる。当該一部の長尺状の部材１０は、図中、１０本であるが、２本以上であり、かつ熱伝導部材１ｅの全ての長尺状の部材１０の数（ここでは、３２本）未満であれば制約はない。好ましくは、当該一部の長尺状の部材１０の数は、熱伝導部材１ｅの全ての長尺状の部材１０の数の半分未満である。なお、固定シート２１に代えて、あるいは固定シート２１と共に、固定シート２２を、固定シート２２側に長くした一部の長尺状の部材１０に固定しても良い。このように、固定シート２１，２２を、当該固定シート２１，２２側に長くした一部に固定することによって、固定シート２１，２２の熱伝導性が熱伝導シート１１の熱伝導性より低い場合であっても、熱源からの冷却源への熱伝導を妨げるリスクが低くなる。 In the heat conductive member 1e according to the fifth modification, a part of the long member 10 constituting the heat conductive member 1e is made longer in the longer direction than the long member 10 other than the part. The fixing sheet 21 is fixed to the part of the elongated member 10. The heat conductive member 1e is a portion of a plurality of long members 10 (the long member 10 indicated by "x" in the figure) constituting the heat conductive member 1e, which is elongated in the Y direction. The fixing sheet 21 is fixed to the part thereof, which is different from the heat conductive member 1. The number of the partially elongated members 10 is 10 in the drawing, but the number is 2 or more, and the number of all the elongated members 10 of the heat conductive member 1e (here, 32). If it is less than, there is no restriction. Preferably, the number of the partial elongated members 10 is less than half the number of all the elongated members 10 of the heat conductive member 1e. In addition, instead of the fixed sheet 21, or together with the fixed sheet 21, the fixed sheet 22 may be fixed to a part of the elongated member 10 elongated toward the fixed sheet 22 side. In this way, when the fixed sheets 21 and 22 are fixed to a part of the fixed sheets 21 and 22 that are elongated toward the fixed sheets 21 and 22, the thermal conductivity of the fixed sheets 21 and 22 is lower than that of the thermal conductive sheet 11. Even so, the risk of interfering with heat conduction from the heat source to the cooling source is low.

次に、第２実施形態に係る熱伝導部材について説明する。第２実施形態において、第１実施形態（各種変形例も含む）と共通する部分については、説明を省略する場合がある。(Second Embodiment)
Next, the heat conductive member according to the second embodiment will be described. In the second embodiment, the description may be omitted with respect to the parts common to the first embodiment (including various modifications).

図９は、第２実施形態に係る熱伝導部材を、その長さ方向に沿う端面（長尺状の部材の開口面）から見た側面図および当該端面の一部Ａの拡大図を示す。 FIG. 9 shows a side view of the heat conductive member according to the second embodiment as viewed from an end surface (open surface of the elongated member) along the length direction thereof, and an enlarged view of a part A of the end surface.

第２実施形態に係る熱伝導部材１ｆは、熱伝導シート１１の外殻の内側に、当該外殻よりも柔軟性の高いクッションシート１３を備える。クッションシート１３は、好ましくは、熱伝導シート１１に対して、密着（非接着状態）、接着あるいは溶着している。クッションシート１３の厚さは、長尺状の部材１０の弾性変形を容易にする趣旨から、熱伝導シート１１の厚さに比べて大きい方が好ましい。クッションシート１３を備えている点以外、熱伝導部材１ｆの構成は、先に説明した熱伝導部材１の構成と同様である。クッションシート１３は、長尺状の部材１０が外圧およびその解除によって弾性変形しやすくするのに寄与する。特に、熱伝導シート１１自体に弾性が乏しい場合に、クッションシート１３の存在は重要である。 The heat conductive member 1f according to the second embodiment includes a cushion sheet 13 having higher flexibility than the outer shell inside the outer shell of the heat conductive sheet 11. The cushion sheet 13 is preferably in close contact (non-adhesive state), adhered or welded to the heat conductive sheet 11. The thickness of the cushion sheet 13 is preferably larger than the thickness of the heat conductive sheet 11 in order to facilitate elastic deformation of the long member 10. The configuration of the heat conductive member 1f is the same as the configuration of the heat conductive member 1 described above, except that the cushion sheet 13 is provided. The cushion sheet 13 contributes to making the elongated member 10 easily elastically deformed by the external pressure and its release. In particular, the presence of the cushion sheet 13 is important when the heat conductive sheet 11 itself has poor elasticity.

クッションシート１３は、好ましくは、シリコーンゴム、ウレタンゴム、イソプレンゴム、エチレンプロピレンゴム、天然ゴム、エチレンプロピレンジエンゴム、ニトリルゴム（ＮＢＲ）あるいはスチレンブタジエンゴム（ＳＢＲ）等の熱硬化性エラストマー； ウレタン系、エステル系、スチレン系、オレフィン系、ブタジエン系、フッ素系等の熱可塑性エラストマー、あるいはそれらの複合物等を含むように構成される。クッションシート１３は、熱伝導シート１１を伝わる熱によって溶融あるいは分解等せずにその形態を維持できる程度の耐熱性の高い材料から構成されるのが好ましい。この実施形態では、クッションシート１３は、より好ましくは、ウレタン系エラストマー中にシリコーンを含浸したもの、あるいはシリコーンゴムにより構成される。クッションシート１３は、その熱伝導性を少しでも高めるために、ゴム中にＡｌ２Ｏ３、ＡｌＮ、ｃＢＮ、ｈＢＮ、ダイヤモンドの粒子等に代表されるフィラーを分散して構成されていても良い。クッションシート１３は、その内部に気泡を含むものの他、気泡を含まないものでも良い。また、「クッションシート」は、柔軟性に富み、熱源の表面に密着可能に弾性変形可能な部材を意味し、かかる意味では「ゴム状弾性体」と読み替えることもできる。さらに、クッションシート１３の変形例としては、上記ゴム状弾性体ではなく、金属を用いて構成することもできる。クッションシート１３は、樹脂やゴム等から形成されたスポンジあるいはソリッド（スポンジのような多孔質ではない構造のもの）で構成することも可能である。The cushion sheet 13 is preferably a thermoplastic elastomer such as silicone rubber, urethane rubber, isoprene rubber, ethylene propylene rubber, natural rubber, ethylene propylene diene rubber, nitrile rubber (NBR) or styrene butadiene rubber (SBR); urethane-based , Ester-based, styrene-based, olefin-based, butadiene-based, fluorine-based and other thermoplastic elastomers, or composites thereof. The cushion sheet 13 is preferably made of a material having high heat resistance to the extent that its shape can be maintained without being melted or decomposed by the heat transmitted through the heat conductive sheet 11. In this embodiment, the cushion sheet 13 is more preferably composed of a urethane-based elastomer impregnated with silicone or a silicone rubber. The cushion sheet 13 may be configured by dispersing a filler typified by Al 2 O 3 , AlN, cBN, hBN, diamond particles, or the like in rubber in order to enhance its thermal conductivity as much as possible. The cushion sheet 13 may contain air bubbles or may not contain air bubbles. Further, the "cushion sheet" means a member that is highly flexible and can be elastically deformed so as to be in close contact with the surface of a heat source, and in this sense, it can be read as a "rubber-like elastic body". Further, as a modification of the cushion sheet 13, a metal may be used instead of the rubber-like elastic body. The cushion sheet 13 can also be made of a sponge or a solid (a structure that is not porous like a sponge) formed of resin, rubber, or the like.

（第３実施形態）
次に、第３実施形態に係る熱伝導部材について説明する。第３実施形態において、前述の各実施形態（第１実施形態の各種変形例も含む）と共通する部分については、説明を省略する場合がある。(Third Embodiment)
Next, the heat conductive member according to the third embodiment will be described. In the third embodiment, the description may be omitted with respect to the parts common to each of the above-described embodiments (including various modifications of the first embodiment).

図１０は、第３実施形態に係る熱伝導部材を、その長さ方向に沿う端面（長尺状の部材の開口面）から見た側面図および当該端面の一部Ａの拡大図を示す。 FIG. 10 shows a side view of the heat conductive member according to the third embodiment as viewed from an end surface (open surface of the elongated member) along the length direction thereof, and an enlarged view of a part A of the end surface.

第３実施形態に係る熱伝導部材１ｇにおいて、長尺状の部材１０の長さ方向から見た面が長円形（すなわち、オーバル形状）である点以外の構成は、第１実施形態に係る熱伝導部材１と共通である。熱伝導シート１１を、スリット１２を備えたオーバル形状の外殻とすると、Ｚ方向の両面が平面、若しくは長尺状の部材１０の幅方向（Ｘ方向）に比べて平面に近くなる。この結果、熱伝導部材１ｅの厚さ方向（Ｚ方向）から熱源および／または冷却源が接触する状態は、より広い面での接触となりやすい。したがって、熱源から熱伝導部材１ｇを介して冷却源に熱を伝導させやすくなる。 In the heat conductive member 1g according to the third embodiment, the configuration other than the point that the surface of the elongated member 10 seen from the length direction is oval (that is, oval shape) is the heat according to the first embodiment. It is common with the conduction member 1. When the heat conductive sheet 11 has an oval-shaped outer shell provided with a slit 12, both sides in the Z direction are flat, or are closer to a flat surface than the width direction (X direction) of the elongated member 10. As a result, the state in which the heat source and / or the cooling source comes into contact with each other from the thickness direction (Z direction) of the heat conductive member 1e tends to be in contact with a wider surface. Therefore, it becomes easy to conduct heat from the heat source to the cooling source via the heat conductive member 1 g.

図１１は、第４実施形態に係る熱伝導部材を、その長さ方向に沿う端面（長尺状の部材の開口面）から見た側面図および当該端面の一部Ａの拡大図を示す。 FIG. 11 shows a side view of the heat conductive member according to the fourth embodiment as viewed from an end surface (open surface of the elongated member) along the length direction thereof, and an enlarged view of a part A of the end surface.

第４実施形態に係る熱伝導部材１ｈは、熱伝導シート１１の外殻の内側に、当該外殻よりも柔軟性の高いクッションシート１３を備える。クッションシート１３を備えている点以外、熱伝導部材１ｈの構成は、先に説明した第３実施形態に係る熱伝導部材１ｇの構成と同様である。クッションシート１３は、熱伝導部材１が外圧およびその解除によって弾性変形しやすくするのに寄与する。特に、熱伝導シート１１自体に弾性が乏しい場合に、クッションシート１３の存在は重要である。 The heat conductive member 1h according to the fourth embodiment includes a cushion sheet 13 having higher flexibility than the outer shell inside the outer shell of the heat conductive sheet 11. The configuration of the heat conductive member 1h is the same as the configuration of the heat conductive member 1g according to the third embodiment described above, except that the cushion sheet 13 is provided. The cushion sheet 13 contributes to making the heat conductive member 1 easily elastically deformed by the external pressure and its release. In particular, the presence of the cushion sheet 13 is important when the heat conductive sheet 11 itself has poor elasticity.

（第５実施形態）
次に、第５実施形態に係る熱伝導部材について説明する。第５実施形態において、前述の各実施形態（第１実施形態の各種変形例も含む）と共通する部分については、説明を省略する場合がある。(Fifth Embodiment)
Next, the heat conductive member according to the fifth embodiment will be described. In the fifth embodiment, the description may be omitted with respect to the parts common to each of the above-described embodiments (including various modifications of the first embodiment).

図１２は、第５実施形態に係る熱伝導部材を、その長さ方向に沿う端面（長尺状の部材の開口面）から見た側面図および当該端面の一部Ａの拡大図を示す。 FIG. 12 shows a side view of the heat conductive member according to the fifth embodiment as viewed from an end surface (open surface of the elongated member) along the length direction thereof, and an enlarged view of a part A of the end surface.

第５実施形態に係る熱伝導部材１ｉは、固定シート２１，２２に代えて、複数の長尺状の部材１０を束ねる固定シート（環状シート３１，３２という）を備える。なお、環状シート３１は、図１２では見えていないが、わかりやすさを優先して、符号「３１」を図中に表示している。環状シート３１の符号「３１」は、図１３以降の図でも同様の趣旨で表示している。環状シート３１，３２は、固定シート２１，２２と同様、長尺状の部材１０の長さ方向（Ｙ方向）の少なくとも両端側にて、長尺状の部材１０の幅方向（Ｘ方向）に沿って、複数の長尺状の部材１０を固定している。しかし、環状シート３１，３２は、熱伝導部材１ｉを構成する複数の長尺状の部材１０を束ねる閉じたループ状の帯である。環状シート３１，３２は、熱伝導部材１ｉの形状を、より保持しやすくするのに寄与している。 The heat conductive member 1i according to the fifth embodiment includes fixed sheets (referred to as annular sheets 31 and 32) for bundling a plurality of elongated members 10 instead of the fixed sheets 21 and 22. Although the annular sheet 31 is not visible in FIG. 12, the reference numeral “31” is displayed in the figure in order to give priority to comprehensibility. The reference numeral “31” of the annular sheet 31 is indicated in the drawings after FIG. 13 for the same purpose. Similar to the fixed sheets 21 and 22, the annular sheets 31 and 32 are provided in the width direction (X direction) of the elongated member 10 at least on both ends in the length direction (Y direction) of the elongated member 10. Along the line, a plurality of elongated members 10 are fixed. However, the annular sheets 31 and 32 are closed loop-shaped bands that bundle a plurality of elongated members 10 constituting the heat conductive member 1i. The annular sheets 31 and 32 contribute to making it easier to hold the shape of the heat conductive member 1i.

この実施形態において、環状シート３１，３２は、突出部２１ａ，２２ａに相当する突出部を備えていない。しかし、環状シート３１，３２に、熱伝導部材１ｇの長さ方向（Ｘ方向）の両側若しくは片側に突出部を備えても良い。固定シート２１，２２に代えて環状シート３１，３２を備える点、および突出部２１ａ，２２ａに相当する突出部を備えていない点を除き、熱伝導部材１ｉの構成は、第２実施形態に係る熱伝導部材１ｆの構成と共通する。 In this embodiment, the annular sheets 31 and 32 do not have protrusions corresponding to the protrusions 21a and 22a. However, the annular sheets 31 and 32 may be provided with protrusions on both sides or one side of the heat conductive member 1 g in the length direction (X direction). The configuration of the heat conductive member 1i relates to the second embodiment, except that the annular sheets 31 and 32 are provided instead of the fixed sheets 21 and 22 and the protrusions corresponding to the protrusions 21a and 22a are not provided. It is common with the configuration of the heat conductive member 1f.

（第６実施形態）
次に、第６実施形態に係る熱伝導部材について説明する。第６実施形態において、前述の各実施形態（第１実施形態の各種変形例も含む）と共通する部分については、説明を省略する場合がある。(Sixth Embodiment)
Next, the heat conductive member according to the sixth embodiment will be described. In the sixth embodiment, the description may be omitted with respect to the parts common to each of the above-described embodiments (including various modifications of the first embodiment).

図１３は、第６実施形態に係る熱伝導部材を、その長さ方向に沿う端面（長尺状の部材の開口面）から見た側面図および当該端面の一部Ａの拡大図を示す。 FIG. 13 shows a side view of the heat conductive member according to the sixth embodiment as viewed from an end surface (open surface of the elongated member) along the length direction thereof, and an enlarged view of a part A of the end surface.

第６実施形態に係る熱伝導部材１ｊは、固定シート２１，２２に代えて、複数の長尺状の部材１０を束ねる固定シート（環状シート３１，３２という）を備える。さらに、環状シート３１，３２は、隣り合う２本の長尺状の部材１０の隙間１４において、長尺状の部材１０の厚さ方向（Ｚ方向）の部位３６を固定されている。このため、環状シート３１，３２は、隣り合う長尺状の部材１０の隙間１４を確保するように、当該隙間１４にてくびれている。すなわち、長尺状の部材１０同士の隙間１４は、環状シート３１，３２の位置で凹部３５を形成している。 The heat conductive member 1j according to the sixth embodiment includes fixed sheets (referred to as annular sheets 31 and 32) for bundling a plurality of elongated members 10 instead of the fixed sheets 21 and 22. Further, in the annular sheets 31 and 32, the portion 36 in the thickness direction (Z direction) of the elongated member 10 is fixed in the gap 14 between the two adjacent elongated members 10. Therefore, the annular sheets 31 and 32 are constricted at the gap 14 so as to secure a gap 14 between the adjacent long members 10. That is, the gap 14 between the elongated members 10 forms a recess 35 at the positions of the annular sheets 31 and 32.

当該部位３６の固定方法は、この実施形態では、接着剤を用いる方法であるが、糸、ステイプル若しくは両面テープなどの固定部材を用いた方法、さらには固定部材を使わないで行う方法（例えば、熱溶着）でも良い。このように、環状シート３１，３２は、長尺状の部材１０を個別に挿入可能に構成されている。したがって、接着層１６を備えなくとも、長尺状の部材１０同士が接触せず、長尺状の部材１０の幅方向（Ｘ方向）の可動領域を規制できる。なお、接着層１６を追加的に用いて、環状シート３１，３２を長尺状の部材１０に、より強固に固定しても良い。また、環状シート３１，３２は、突出部２１ａ，２２ａに相当する突出部を備えていない。しかし、環状シート３１，３２に、熱伝導部材１ｈの長さ方向（Ｘ方向）の両側若しくは片側に突出部を備えても良い。 In this embodiment, the method of fixing the portion 36 is a method using an adhesive, but a method using a fixing member such as a thread, a staple, or a double-sided tape, and a method using no fixing member (for example,). Heat welding) is also acceptable. As described above, the annular sheets 31 and 32 are configured so that the elongated member 10 can be individually inserted. Therefore, even if the adhesive layer 16 is not provided, the elongated members 10 do not come into contact with each other, and the movable region of the elongated members 10 in the width direction (X direction) can be regulated. The adhesive layer 16 may be additionally used to more firmly fix the annular sheets 31 and 32 to the elongated member 10. Further, the annular sheets 31 and 32 do not have a protrusion corresponding to the protrusions 21a and 22a. However, the annular sheets 31 and 32 may be provided with protrusions on both sides or one side of the heat conductive member 1h in the length direction (X direction).

固定シート２１，２２に代えて環状シート３１，３２を用いている点、部位３６にて環状シート３１，３２をＺ方向で固定している点、接着層１６を必ずしも要しない点、および突出部２１ａ，２２ａに相当する突出部を備えていない点を除き、熱伝導部材１ｊの構成は、第４実施形態に係る熱伝導部材１ｈの構成と共通する。 The points where the annular sheets 31 and 32 are used instead of the fixed sheets 21 and 22, the points where the annular sheets 31 and 32 are fixed in the Z direction at the portion 36, the points where the adhesive layer 16 is not always required, and the protruding portion. The configuration of the heat conductive member 1j is the same as the configuration of the heat conductive member 1h according to the fourth embodiment, except that the heat conductive member 1j is not provided with the protrusions corresponding to the 21a and 22a.

（第７実施形態）
次に、第７実施形態に係る熱伝導部材について説明する。第７実施形態において、前述の各実施形態（第１実施形態の各種変形例も含む）と共通する部分については、説明を省略する場合がある。(7th Embodiment)
Next, the heat conductive member according to the seventh embodiment will be described. In the seventh embodiment, the description may be omitted with respect to the parts common to each of the above-described embodiments (including various modifications of the first embodiment).

図１４は、第７実施形態に係る熱伝導部材を、その長さ方向に沿う端面（長尺状の部材の開口面）から見た側面図および当該端面の一部Ａの拡大図を示す。 FIG. 14 shows a side view of the heat conductive member according to the seventh embodiment as viewed from an end surface (open surface of the elongated member) along the length direction thereof, and an enlarged view of a part A of the end surface.

第７実施形態に係る熱伝導部材１ｋは、長尺状の部材１０にスリット１２を備えていない。スリット１２を備えていない点以外、熱伝導部材１ｉの構成は、第４実施形態に係る熱伝導部材１ｈの構成と共通する。長尺状の部材１０の外殻を構成する熱伝導シート１７は、上述の熱伝導シート１１と異なり、長尺状の部材１０の外側面に沿って完全に閉じた形態を有する。クッションシート１３も熱伝導シート１１の内側の面に沿って閉じた形態を有する。Ｚ方向からの外圧によって熱伝導シート１７が十分に変形しやすい場合には、長尺状の部材１０にスリット１２を備えていなくとも良い。 The heat conductive member 1k according to the seventh embodiment does not have a slit 12 in the elongated member 10. The configuration of the heat conductive member 1i is the same as the configuration of the heat conductive member 1h according to the fourth embodiment, except that the slit 12 is not provided. Unlike the heat conductive sheet 11 described above, the heat conductive sheet 17 constituting the outer shell of the elongated member 10 has a completely closed form along the outer surface of the elongated member 10. The cushion sheet 13 also has a form closed along the inner surface of the heat conductive sheet 11. When the heat conductive sheet 17 is sufficiently easily deformed by the external pressure from the Z direction, the elongated member 10 may not be provided with the slit 12.

（第８実施形態）
次に、第８実施形態に係る熱伝導部材について説明する。第８実施形態において、前述の各実施形態（第１実施形態の各種変形例も含む）と共通する部分については、説明を省略する場合がある。(8th Embodiment)
Next, the heat conductive member according to the eighth embodiment will be described. In the eighth embodiment, the description may be omitted with respect to the parts common to each of the above-described embodiments (including various modifications of the first embodiment).

図１５は、第８実施形態に係る熱伝導部材の斜視図を示す。図１６は、図１５の熱伝導部材をその最も広い面側から見た平面図を示す。 FIG. 15 shows a perspective view of the heat conductive member according to the eighth embodiment. FIG. 16 shows a plan view of the heat conductive member of FIG. 15 as viewed from the widest surface side thereof.

第８実施形態に係る熱伝導部材１ｌにおいて、長尺状の部材１０の長さ方向の開口面の形状は長円形である。熱伝導部材１ｌは、第７実施形態に係る熱伝導部材１ｋと同様、長尺状の部材１０の側面にて閉じた筒状のクッションシート１３を備える。筒状のクッションシート１３の外側面には、帯状の熱伝導シート１８が巻回されている。より具体的には、熱伝導シート１８は、筒状のクッションシート１３に対してスパイラル状に巻きながら長尺状の部材１０の長さ方向（Ｙ方向）に進行するシートである。熱伝導シート１８をスパイラル状に巻いた際のスパイラル状の隙間は、スリット１２に相当し、熱伝導シート１８の外殻の変形容易性に寄与する。すなわち、長尺状の部材１０の外側面を熱伝導シート１８にてスパイラル状に覆うと、長尺状の部材１０の変形に伴い熱伝導シート１８も変形しやすい。このため、熱伝導部材１ｌの使用中、熱伝導シート１８が破損するリスクを低減できる。 In the heat conductive member 1l according to the eighth embodiment, the shape of the opening surface in the length direction of the elongated member 10 is oval. Similar to the heat conductive member 1k according to the seventh embodiment, the heat conductive member 1l includes a tubular cushion sheet 13 closed on the side surface of the elongated member 10. A band-shaped heat conductive sheet 18 is wound around the outer surface of the tubular cushion sheet 13. More specifically, the heat conductive sheet 18 is a sheet that advances in the length direction (Y direction) of the elongated member 10 while spirally wound around the tubular cushion sheet 13. The spiral gap when the heat conductive sheet 18 is wound in a spiral shape corresponds to the slit 12 and contributes to the deformability of the outer shell of the heat conductive sheet 18. That is, if the outer surface of the elongated member 10 is spirally covered with the heat conductive sheet 18, the heat conductive sheet 18 is likely to be deformed as the elongated member 10 is deformed. Therefore, it is possible to reduce the risk of the heat conductive sheet 18 being damaged during the use of the heat conductive member 1 liter.

複数の長尺状の部材１０は、固定シート２１，２２の他に、糸４１，４２によっても接続されている。糸４１，４２は、手縫いにより、あるいはソーイングマシンを用いて、長尺状の部材１０に固定されている。糸４１は、固定シート２１の近傍であって、固定シート２１とは別の位置にて、長尺状の部材１０の幅方向（Ｘ方向）に沿って備えられる。糸４２も、固定シート２２の近傍であって、固定シート２２とは別の位置にて、長尺状の部材１０の幅方向（Ｘ方向）に沿って備えられる。熱伝導部材１ｌは、糸４１，４２によって複数の長尺状の部材１０を接続して成るが、糸４１，４２のみでは形状を保持することが難しい。糸４１，４２に加えて、固定シート２１，２２を備えることにより、熱伝導部材１ｌの形状（平面視にて、おおよそ長方形）を保持しやすくなる。なお、糸４１，４２は、固定シート２１，２２と長尺状の部材１０との間に挟まれる位置に存在していても良い。 The plurality of elongated members 10 are connected by threads 41 and 42 in addition to the fixing sheets 21 and 22. The threads 41 and 42 are fixed to the elongated member 10 by hand sewing or by using a sewing machine. The thread 41 is provided in the vicinity of the fixed sheet 21 at a position different from that of the fixed sheet 21 along the width direction (X direction) of the elongated member 10. The thread 42 is also provided near the fixed sheet 22 at a position different from that of the fixed sheet 22 along the width direction (X direction) of the elongated member 10. The heat conductive member 1l is formed by connecting a plurality of elongated members 10 with threads 41 and 42, but it is difficult to maintain the shape only with the threads 41 and 42. By providing the fixing sheets 21 and 22 in addition to the threads 41 and 42, it becomes easy to hold the shape (approximately rectangular shape in a plan view) of the heat conductive member 1l. The threads 41 and 42 may be present at positions sandwiched between the fixed sheets 21 and 22 and the elongated member 10.

なお、スパイラル状の熱伝導シート１８をクッションシート１３の外側に備える点、糸４１，４２を備える点以外、熱伝導部材１ｌの構成は、第７実施形態に係る熱伝導部材１ｋの構成と共通する。 The configuration of the heat conductive member 1l is the same as the configuration of the heat conductive member 1k according to the seventh embodiment, except that the spiral heat conductive sheet 18 is provided on the outside of the cushion sheet 13 and the threads 41 and 42 are provided. do.

２．バッテリー
次に、熱伝導部材を備えるバッテリーの実施形態について説明する。2. 2. Battery Next, an embodiment of a battery including a heat conductive member will be described.

図１７は、一実施形態に係るバッテリーの概略的な縦断面図を示す。 FIG. 17 shows a schematic vertical sectional view of the battery according to the embodiment.

この実施形態において、バッテリー５０は、例えば、電気自動車用のバッテリーであって、多数のバッテリーセル（単に、セルとも称する。）６０を備える。バッテリー５０は、一方に開口する有底型の筐体５１を備える。筐体５１は、好ましくは、アルミニウム若しくはアルミニウム基合金から成る。セル６０は、筐体５１の内部５４に配置される。複数のセル６０は、好ましくは、筐体５１内において、その両側からネジ等を利用して圧縮する方向に力を与えられている（不図示）。筐体５１の底部５２には、冷却剤５５の一例である冷却水を流すために、１または複数の水冷パイプ５３が備えられている。 In this embodiment, the battery 50 is, for example, a battery for an electric vehicle and includes a large number of battery cells (simply also referred to as cells) 60. The battery 50 includes a bottomed housing 51 that opens to one side. The housing 51 is preferably made of aluminum or an aluminum-based alloy. The cell 60 is arranged inside 54 of the housing 51. The plurality of cells 60 are preferably subjected to a force in the housing 51 in the direction of compression from both sides thereof by using screws or the like (not shown). The bottom 52 of the housing 51 is provided with one or more water cooling pipes 53 for flowing cooling water, which is an example of the cooling agent 55.

セル６０は、底部５２との間に、熱伝導部材１を挟むようにして筐体５１内に配置されている。すなわち、バッテリー５０は、筐体５１内に複数のセル６０を備えており、セル６０と筐体５１との間に熱伝導部材１を備えている。熱伝導部材１に備えられている複数の長尺状の部材１０は、幅方向（Ｘ方向）および長さ方向（Ｙ方向）に直交する厚さ方向（Ｚ方向）にてセル６０と筐体５１との間に挟まれている。このような構造のバッテリー５０において、セル６０は、熱伝導部材１を通じて筐体５１に伝熱して、水冷によって効果的に除熱される。なお、冷却剤５５は、冷却水に限定されず、液体窒素、エタノール等の有機溶剤も含むように解釈される。冷却剤５５は、冷却に用いられる状況下にて、液体であるとは限らず、気体あるいは固体でも良い。また、この実施形態では、熱伝導部材１は、１３個のセル６０を載置しているが、セル６０の個数は１３個に限定されない。複数の長尺状の部材１０は、セル６０を載置するとその重さで圧縮され扁平の形態になる。なお、本願では、「縦断面」とは、バッテリー５０の筐体５１の内部５４における上方開口面から底部５２へと垂直に切断する方向の断面を意味する。 The cell 60 is arranged in the housing 51 so as to sandwich the heat conductive member 1 with the bottom portion 52. That is, the battery 50 includes a plurality of cells 60 in the housing 51, and a heat conductive member 1 is provided between the cells 60 and the housing 51. The plurality of elongated members 10 provided in the heat conductive member 1 include the cell 60 and the housing in the thickness direction (Z direction) orthogonal to the width direction (X direction) and the length direction (Y direction). It is sandwiched between 51 and 51. In the battery 50 having such a structure, the cell 60 transfers heat to the housing 51 through the heat conductive member 1 and is effectively removed by water cooling. The coolant 55 is not limited to the cooling water, but is interpreted to include an organic solvent such as liquid nitrogen and ethanol. The coolant 55 is not limited to a liquid under the conditions used for cooling, and may be a gas or a solid. Further, in this embodiment, the heat conductive member 1 mounts 13 cells 60, but the number of cells 60 is not limited to 13. When the cell 60 is placed, the plurality of elongated members 10 are compressed by the weight thereof to form a flat shape. In the present application, the "vertical cross section" means a cross section in the inner 54 of the housing 51 of the battery 50 in the direction of cutting vertically from the upper opening surface to the bottom 52.

バッテリー５０は、熱伝導部材１に限られず、上述の各実施形態に係る熱伝導部材１ａ～１ｌのいずれかを備えていても良い。また、熱伝導部材１，１ａ～１ｌ（以後、「熱伝導部材１等」という。）は、その厚さ方向（Ｚ方向）にあるいずれの面をセル６０の底部に接触させるように、筐体５１に備えられても良い。 The battery 50 is not limited to the heat conductive member 1, and may include any of the heat conductive members 1a to 1l according to each of the above-described embodiments. Further, the heat conductive members 1, 1a to 1 l (hereinafter referred to as "heat conductive member 1 and the like") have a casing so that any surface in the thickness direction (Z direction) is in contact with the bottom of the cell 60. It may be provided on the body 51.

長尺状の部材１０の長さ方向（Ｙ方向）から見た面は、長円形、四角形若しくは五角以上の多角形である。複数の長尺状の部材１０は、長尺状の部材１０の平面若しくは最も平面に近い面が幅方向（Ｘ方向）に沿って並べられている。特に、長尺状の部材１０の厚さ方向（Ｚ方向）にある両面は、平面か、正確には平面といえなくても当該外側面のどの位置の面よりも平面に近い。長尺状の部材１０をこのような形状にして、熱伝導部材１等の構成要素とすることにより、熱伝導部材１等とセル６０および／または筐体５１の底部５３と、より広い面にて接触しやすくなる。これは、熱伝導部材１等のセル６０からの除熱性能をより高めることにつながる。 The surface of the elongated member 10 seen from the length direction (Y direction) is an oval, a quadrangle, or a polygon having a pentagon or more. In the plurality of elongated members 10, the plane or the surface closest to the plane of the elongated member 10 is arranged along the width direction (X direction). In particular, both sides of the elongated member 10 in the thickness direction (Z direction) are flat, or even if they are not exactly flat, they are closer to a flat surface than any position on the outer surface. By forming the elongated member 10 into such a shape and making it a component of the heat conductive member 1 and the like, the heat conductive member 1 and the like and the cell 60 and / or the bottom 53 of the housing 51 can be formed on a wider surface. It becomes easier to contact. This leads to further enhancing the heat removal performance from the cell 60 of the heat conductive member 1 and the like.
