Description

本発明は、複数の電池モジュールを重ねて構成される放熱構造を有する集合電池に関し、特に、二次集合電池の外部にある放熱構造に関するものである。 The present invention relates to an assembled battery having a heat dissipation structure configured by stacking a plurality of battery modules, and more particularly to a heat dissipation structure outside a secondary assembled battery.

電池が高電量を出力できるために、多数の単一電池を直列接続し、又は並列接続して集合電池を構成することが一般的である。 In order for a battery to output a high electric energy, it is common to configure a collective battery by connecting a large number of single batteries in series or in parallel.

高電量を出力できる集合電池の充放電の過程中には、前記集合電池の内部にある各単一電池が熱を放出して全体の温度が上昇する。電池の温度が上昇すると、電池は正常に稼動できなくなるという問題があった。このような問題を解決するために、図１に示すように、特許文献１の集合電池１０の構成が提案されていた。集合電池１０の構成は、各単一電池１１の間に仕切りブロック１２が設けられ、仕切りブロック１２の一側の表面に凹凸構造１３が複数成形される。これにより、各単一電池１１と仕切りブロック１２を重ねると、放熱するための空気通路１４が複数形成され、集合電池１０の温度を降下できる。 During the charging / discharging process of the assembled battery that can output a high electric energy, each single battery inside the assembled battery releases heat, and the overall temperature rises. When the temperature of the battery rises, there is a problem that the battery cannot operate normally. In order to solve such a problem, as shown in FIG. 1, the configuration of the assembled battery 10 of Patent Document 1 has been proposed. In the configuration of the assembled battery 10, a partition block 12 is provided between each single battery 11, and a plurality of uneven structures 13 are formed on one surface of the partition block 12. Thereby, when each single battery 11 and the partition block 12 are overlapped, a plurality of air passages 14 for radiating heat are formed, and the temperature of the assembled battery 10 can be lowered.

しかしながら、このような構成によれば、放熱の効果は良くない。その原因は下記にある。
（１）集合電池１０を組付けた後、仕切りブロック１２の凹凸構造１３が成形された面は、単一電池１１の一面をカバーし、直接に外部に露呈することではないため、電池からの熱を有効に放熱できない。 However, according to such a configuration, the effect of heat dissipation is not good. The cause is as follows.
(1) After the assembled battery 10 is assembled, the surface on which the uneven structure 13 of the partition block 12 is molded covers one surface of the single battery 11 and is not directly exposed to the outside. The heat cannot be effectively dissipated.

（２）集合電池１０を組付けた後、各仕切りブロック１２の凹凸構造１３によって形成される空気通路１４が互いに連通せず、且つ空気通路１４の外部と連通する開口が極めて狭いため、空気の流通が良くなく、電池からの熱を有効に放熱できない。 (2) After the assembled battery 10 is assembled, the air passages 14 formed by the concavo-convex structure 13 of each partition block 12 do not communicate with each other, and the opening communicating with the outside of the air passage 14 is extremely narrow. Distribution is not good and heat from the battery cannot be effectively dissipated.

以下、本発明の実施の形態を図面に基づいて説明する。
まず、図２乃至図５を参照する。本発明の一実施例の放熱構造付き集合電池は、電池モジュール２０１、２０２の間には、四つの放熱具３０と、四つの間隔スリーブ４０とが設けられ、そして四つのねじ軸５０が上記の部材を挿通して締結する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
First, reference will be made to FIGS. In the assembled battery with a heat dissipation structure of one embodiment of the present invention, four heat dissipating tools 30 and four spacing sleeves 40 are provided between the battery modules 201 and 202, and four screw shafts 50 are arranged as described above. Insert the member and fasten.

電池モジュール２０１、２０２は、金属連接片２１１を介して複数の単一電池２１を電気的に接続して、矩形を呈するフレーム２２に組み付けられ、共用の出力ヘッド２３を有する。フレーム２２の対応する二つの面は、内面２４と、表面２５と、をそれぞれ定義する。フレーム２２の対応する二つの側面は、左側面２６と、右側面２７と、をそれぞれ定義する。各単一電池２１の一側面はフレーム２２の内面２４から外部に露呈する。フレーム２２の四つのコナーに貫通孔２８がそれぞれ設けられる。 The battery modules 201 and 202 are electrically connected to a plurality of single batteries 21 via metal connecting pieces 211, assembled to a rectangular frame 22, and have a common output head 23. Two corresponding surfaces of the frame 22 define an inner surface 24 and a surface 25, respectively. Two corresponding side surfaces of the frame 22 define a left side surface 26 and a right side surface 27, respectively. One side surface of each single battery 21 is exposed to the outside from the inner surface 24 of the frame 22. Through holes 28 are respectively provided in the four corners of the frame 22.

放熱具３０は金属で作製されるプレート３１を有する。プレート３１の二つの対応する端部に締結穴３２がそれぞれ設けられる。プレート３１の二つの対応する端面は、通路面３３と、接触面３４と、をそれぞれ定義する。接触面３４の一側に放熱フィン面３５が立設されている。放熱フィン面３５の外面に複数のフィン３５１が距離を置いて配列されている。放熱具３０は接触面３４及び電池モジュール２０１、２０２の内面２４から露呈する単一電池２１の一側面と接触する。放熱フィン面３５は電池モジュール２０１、２０２の左側面２６と右側面２７とに対応する。放熱具３０の締結穴３２はフレーム２２に設けられる貫通孔２８に対応する。これにより、各電池モジュール２０１、２０２はそれぞれ二つの放熱具３０と接触する。 The radiator 30 has a plate 31 made of metal. Fastening holes 32 are respectively provided at two corresponding ends of the plate 31. Two corresponding end surfaces of the plate 31 define a passage surface 33 and a contact surface 34, respectively. A heat radiating fin surface 35 is erected on one side of the contact surface 34. A plurality of fins 351 are arranged on the outer surface of the radiating fin surface 35 at a distance. The radiator 30 is in contact with one side surface of the single battery 21 exposed from the contact surface 34 and the inner surfaces 24 of the battery modules 201 and 202. The heat radiation fin surface 35 corresponds to the left side surface 26 and the right side surface 27 of the battery modules 201 and 202. A fastening hole 32 of the radiator 30 corresponds to a through hole 28 provided in the frame 22. As a result, each of the battery modules 201 and 202 is in contact with the two radiators 30.

間隔スリーブ４０は、各放熱具３０の締結穴３２に設けられる。 The spacing sleeve 40 is provided in the fastening hole 32 of each radiator 30.

ねじ軸５０は、電池モジュール２０１の貫通孔２８、放熱具３０の締結穴３２、間隔スリーブ４０と電池モジュール２０２の貫通孔２８を順次に挿通して締結する。これにより、電池モジュール２０１、２０２の間に位置する通路面３３同士がある距離を置いて空間を形成して放熱通路６０を構成する。 The screw shaft 50 is inserted through the through hole 28 of the battery module 201, the fastening hole 32 of the radiator 30, the spacing sleeve 40 and the through hole 28 of the battery module 202 in order and fastened. Thus, a space is formed with a certain distance between the passage surfaces 33 located between the battery modules 201 and 202 to form the heat radiation passage 60.

次に、本発明の一実施例の使用方法及び効果を説明する。図２乃至図５を参照する。集合電池の熱は各単一電池２１の表面から放出される。放熱具３０の接触面３４は、各単一電池２１の一側面と直接に接触する。単一電池２１からの熱は、プレート３１を介して放熱フィン面３５に熱伝導されて、放熱フィン面３５に設けられるフィン３５１により大気と接触することにより、温度を降下できる。 Next, a method of use and effects of an embodiment of the present invention will be described. Please refer to FIG. 2 to FIG. The heat of the assembled battery is released from the surface of each single battery 21. The contact surface 34 of the radiator 30 is in direct contact with one side surface of each single battery 21. The heat from the single battery 21 is thermally conducted to the heat radiating fin surface 35 through the plate 31, and the temperature can be lowered by coming into contact with the atmosphere by the fin 351 provided on the heat radiating fin surface 35.

特に、図５に示すように、集合電池の電池モジュール２０１、２０２の間に間隔スリーブ４０を設けることにより、電池モジュール２０１、２０２がある距離を置いて分離している。これにより、電池モジュール２０１、２０２の直接の接触によって熱が蓄えることを回避でき、そして電池モジュール２０１、２０２の間に放熱通路６０が形成されるため、集合電池の外部の冷たい空気が放熱通路６０内の熱い空気と熱交換できる。 In particular, as shown in FIG. 5, the battery modules 201 and 202 are separated by a certain distance by providing a spacing sleeve 40 between the battery modules 201 and 202 of the assembled battery. Thus, heat can be prevented from being stored due to direct contact between the battery modules 201 and 202, and the heat radiation path 60 is formed between the battery modules 201 and 202. Heat exchange with hot air inside.

図３及び図４に示すように、本発明の集合電池のフィン３５１は、各電池モジュール２０１、２０２の左側面２６と右側面２７とに設けられることにより、集合電池の熱が内面２４に蓄えることを回避でき、そしてフィンを空気の流通の良い箇所に向かせることができる。 As shown in FIGS. 3 and 4, the fins 351 of the battery assembly of the present invention are provided on the left side surface 26 and the right side surface 27 of each battery module 201, 202, so that the heat of the battery assembly is stored on the inner surface 24. Can be avoided, and the fin can be directed to a location with good air circulation.

特に、本発明の集合電池の設計は、ねじ軸により電池モジュール２０１、２０２を重ねるように組付けるため、図６に示すように、電池モジュール２０１、２０２に電池モジュール２０３、２０４を増設したい場合には、増長されたねじ軸５０ａにより電池モジュール２０１、２０２、２０３、２０４を重ねるように組付けることができる。換言すると、本発明の放熱構造付き集合電池によれば、電池モジュールの増設は極めて容易である。 In particular, the design of the assembled battery of the present invention is performed when the battery modules 201 and 202 are added to the battery modules 201 and 202 as shown in FIG. Can be assembled so that the battery modules 201, 202, 203, and 204 are overlapped by the increased screw shaft 50a. In other words, according to the assembled battery with a heat dissipation structure of the present invention, it is extremely easy to add a battery module.
