　ヒートパイプ部１２０５は、その内部に冷却媒体として水を含んでおり、筐体１２００内において上下方向に延設される。放熱部１２０６は、ヒートパイプ部１２０５に接続された部材であり、筐体１２００上面において露出している。本実施形態においては、ヒートパイプ部１２０５は、更に筐体１２００上方部において筐体１２００上面に沿って延設されており、この部分において放熱部１２０６に内包される。放熱部１２０６には、熱伝導率の比較的高い金属（例えば鉄、アルミニウム、それらの合金等）が用いられる。ヒートパイプ部１２０５内の冷却媒体としての水は、バッテリ部１２０１から熱を受けて蒸発して放熱部１２０６に向かい、その後、放熱部１２０６での放熱により冷却されて液化することとなる。このような構造により、ヒートパイプ部１２０５はバッテリ部１２０１と熱交換を行う。尚、本実施形態においては、ヒートパイプ部１２０５及び放熱部１２０６は、把持部１２０４の両側方に一対設けられる。 (4) The heat pipe section 1205 contains water as a cooling medium therein, and extends vertically in the housing 1200. The heat radiating portion 1206 is a member connected to the heat pipe portion 1205, and is exposed on the upper surface of the housing 1200. In the present embodiment, the heat pipe portion 1205 further extends along the upper surface of the housing 1200 at an upper portion of the housing 1200, and is included in the heat radiating portion 1206 at this portion. For the heat radiating portion 1206, a metal having a relatively high thermal conductivity (for example, iron, aluminum, or an alloy thereof) is used. The water as a cooling medium in the heat pipe unit 1205 receives heat from the battery unit 1201, evaporates and goes to the heat radiating unit 1206, and is cooled and liquefied by the heat radiating in the heat radiating unit 1206. With such a structure, the heat pipe unit 1205 performs heat exchange with the battery unit 1201. In this embodiment, a pair of the heat pipe 1205 and the heat radiator 1206 are provided on both sides of the grip 1204.
　このようなモバイルバッテリユニット１２０の構造によれば、バッテリ部１２０１の電力を用いたことにより発生した熱はヒートパイプ部１２０５を介して放熱部１２０６に集められることとなる。 According to the structure of the mobile battery unit 120, heat generated by using the power of the battery unit 1201 is collected in the heat radiating unit 1206 through the heat pipe unit 1205.
　図３は、電動車両１の他の構成要素を説明するための模式図である。ここでは図を見易くするため、フレーム１０５～１０９を不図示とした。電動車両１は、図３に示されるように、熱伝導部材１３０、熱交換器１３１および接続部１３２を更に備える。 FIG. 3 is a schematic diagram for explaining other components of the electric vehicle 1. Here, the frames 105 to 109 are not shown to make the figure easy to see. The electric vehicle 1 further includes a heat conducting member 130, a heat exchanger 131, and a connection part 132, as shown in FIG.
　熱伝導部材１３０は、車体１００に対して開閉自在なシート１０３の下部に設けられ、シート１０３の開閉に従ってシート１０３と共に回動する。シート１０３が閉じられた状態（即ち図３の状態）では、熱伝導部材１３０は、モバイルバッテリユニット１２０の筐体１２００上面を押圧して放熱部１２０６と当接する。本実施形態では、熱伝導部材１３０には、熱伝導率の比較的高い金属（例えば鉄、アルミニウム、それらの合金等）が用いられる。バッテリ部１２０１で発生しヒートパイプ部１２０５を介して放熱部１２０６に集められた上記熱は、放熱部１２０６と熱伝導部材１３０とが接触することで、熱伝導部材１３０に伝搬する。 The heat conducting member 130 is provided below the seat 103 which can be opened and closed with respect to the vehicle body 100, and rotates together with the seat 103 according to the opening and closing of the seat 103. In a state where the sheet 103 is closed (that is, a state in FIG. 3), the heat conducting member 130 presses the upper surface of the housing 1200 of the mobile battery unit 120 and comes into contact with the heat radiation portion 1206. In the present embodiment, a metal having a relatively high heat conductivity (for example, iron, aluminum, or an alloy thereof) is used for the heat conductive member 130. The heat generated in the battery unit 1201 and collected by the heat radiating unit 1206 via the heat pipe unit 1205 is transmitted to the heat conductive member 130 when the heat radiating unit 1206 contacts the heat conductive member 130.
　本実施形態においては、２つのモバイルバッテリユニット１２０ａ及び１２０ｂは、共に傾斜した姿勢で、車体前後方向に並設される。そのため、モバイルバッテリユニット１２０ａ及び１２０ｂの上面は段差を形成しており、それらの放熱部１２０６は一直線上には並んでいない。よって、本実施形態では、熱伝導部材１３０は、車体前後方向に延設されると共に段差部を形成し、この段差部においてモバイルバッテリユニット１２０ａ及び１２０ｂの双方と係合する。 に お い て In the present embodiment, the two mobile battery units 120a and 120b are arranged side by side in the vehicle front-rear direction with both of them inclined. Therefore, the upper surfaces of the mobile battery units 120a and 120b form a step, and the heat radiating portions 1206 are not arranged in a straight line. Therefore, in the present embodiment, the heat conducting member 130 extends in the front-rear direction of the vehicle body and forms a step, and engages with both the mobile battery units 120a and 120b at the step.
　放熱部１２０６と熱伝導部材１３０との接触面について、放熱部１２０６の上面と熱伝導部材１３０の下面とは、本実施形態では平坦面とするが、他の実施形態として波状あるいは凹凸状に設けられてもよい。この場合、放熱部１２０６と熱伝導部材１３０との接触面を大きくすることができ、放熱部１２０６から熱伝導部材１３０への熱伝搬効率が向上しうる。また、熱伝導部材１３０は、シート１０３が閉じられた状態ではモバイルバッテリユニット１２０を押圧するため、モバイルバッテリユニット１２０の位置を固定ないし係止する機能を兼ねる。よって、放熱部１２０６と熱伝導部材１３０との接触面が波状あるいは凹凸状の場合にはモバイルバッテリユニット１２０の位置ずれを適切に抑制可能となる。 Regarding the contact surface between the heat radiating portion 1206 and the heat conducting member 130, the upper surface of the heat radiating portion 1206 and the lower surface of the heat conducting member 130 are flat surfaces in this embodiment, but are provided in a wavy or uneven shape as another embodiment. You may be. In this case, the contact surface between the heat radiating portion 1206 and the heat conducting member 130 can be increased, and the efficiency of heat propagation from the heat radiating portion 1206 to the heat conducting member 130 can be improved. In addition, since the heat conductive member 130 presses the mobile battery unit 120 when the sheet 103 is closed, the heat conductive member 130 also has a function of fixing or locking the position of the mobile battery unit 120. Therefore, when the contact surface between the heat radiating portion 1206 and the heat conducting member 130 is wavy or uneven, the displacement of the mobile battery unit 120 can be appropriately suppressed.
　熱交換器１３１は、本実施形態では、ヒートシンク（放熱用フィン）とし、車体１００後方に配置されるものとする。接続部１３２は、熱伝導部材１３０と熱交換器１３１とを接続する。本実施形態では、熱交換器１３１及び接続部１３２は一体成形され、それらには熱伝導率の比較的高い金属（例えば鉄、アルミニウム、それらの合金等）が用いられる。 In the present embodiment, the heat exchanger 131 is a heat sink (radiation fin) and is arranged behind the vehicle body 100. The connection part 132 connects the heat conduction member 130 and the heat exchanger 131. In the present embodiment, the heat exchanger 131 and the connecting portion 132 are integrally formed, and a metal having a relatively high thermal conductivity (for example, iron, aluminum, or an alloy thereof) is used for them.
　ここで、電動車両１の走行時においては、車体１００後方には負圧が発生する。そのため、モバイルバッテリユニット１２０の放熱部１２０６から熱伝導部材１３０に伝搬した熱は、接続部１３２を介して熱交換器１３１に伝わった後、車体１００外に適切に放出されることとなる。 Here, when the electric vehicle 1 is traveling, a negative pressure is generated behind the vehicle body 100. Therefore, the heat transmitted from the heat radiating portion 1206 of the mobile battery unit 120 to the heat conducting member 130 is transmitted to the heat exchanger 131 via the connecting portion 132, and is appropriately released to the outside of the vehicle body 100.
　更に本実施形態では、熱交換器１３１は後輪１０２の上方に位置する。そのため、走行時においては後輪１０２の回転による風が熱交換器１３１に当たり、モバイルバッテリユニット１２０の放熱部１２０６から熱伝導部材１３０に伝搬した熱は、更に適切に車体１００外に放出されることとなる。 In this embodiment, the heat exchanger 131 is located above the rear wheel 102. Therefore, during traveling, the wind generated by the rotation of the rear wheels 102 hits the heat exchanger 131, and the heat transmitted from the heat radiating portion 1206 of the mobile battery unit 120 to the heat conducting member 130 is more appropriately released to the outside of the vehicle body 100. Becomes
　本実施形態では、熱交換器１３１及び接続部１３２は車体１００に固定され、熱伝導部材１３０と接続部１３２とは、シート１０３を閉じた場合に連結し且つシート１０３を開いた場合に分離するように構成されるものとする。他の実施形態として、熱交換器１３１及び接続部１３２は熱伝導部材１３０と一体にシート１０３に固定されてもよい。 In this embodiment, the heat exchanger 131 and the connecting portion 132 are fixed to the vehicle body 100, and the heat conducting member 130 and the connecting portion 132 are connected when the seat 103 is closed and separated when the seat 103 is opened. It is configured as follows. As another embodiment, the heat exchanger 131 and the connection part 132 may be fixed to the sheet 103 integrally with the heat conducting member 130.
　また、前述のとおり、放熱部１２０６は、把持部１２０４の両側方に一対設けられる（図２Ｄ参照）。換言すると、把持部１２０４は、上面視（平面視）において放熱部１２０６からシフトした位置に設けられる。よって、モバイルバッテリユニット１２０を車体１００に装着してシート１０３を閉じる際には、熱伝導部材１３０は把持部１２０４と干渉しないで放熱部１２０６と当接可能となる。また、モバイルバッテリユニット１２０を取り外す際には、ユーザは放熱部１２０６に触れることなく把持部１２０４を把持可能となる。 As described above, a pair of heat radiating portions 1206 are provided on both sides of the grip portion 1204 (see FIG. 2D). In other words, the grip portion 1204 is provided at a position shifted from the heat radiating portion 1206 in a top view (plan view). Therefore, when the mobile battery unit 120 is mounted on the vehicle body 100 and the seat 103 is closed, the heat conducting member 130 can contact the heat radiating portion 1206 without interfering with the grip portion 1204. Further, when removing the mobile battery unit 120, the user can grip the grip portion 1204 without touching the heat radiating portion 1206.
　以上、本実施形態によれば、モバイルバッテリユニット１２０の上面には、ヒートパイプ部１２０５に接続された放熱部１２０６が露出して設けられる。そして、モバイルバッテリユニット１２０の熱を車体１００外に導くための熱伝導部材１３０が、この放熱部１２０６と当接可能に設けられる。本実施形態では、モバイルバッテリユニット１２０を装着してシート１０３を閉じた場合、熱伝導部材１３０が放熱部１２０６と当接する。これにより、モバイルバッテリユニット１２０で生じた熱は、放熱部１２０６から熱伝導部材１３０を介して車体１００外に向かって導かれることとなる。よって、本実施形態によれば、着脱自在なモバイルバッテリユニット１２０を用いることによるユーザビリティを向上させつつモバイルバッテリユニット１２０の放熱効率を比較的簡素な構成で向上可能となる。 According to the present embodiment, the heat radiating portion 1206 connected to the heat pipe portion 1205 is provided on the upper surface of the mobile battery unit 120 so as to be exposed. A heat conducting member 130 for guiding the heat of the mobile battery unit 120 to the outside of the vehicle body 100 is provided so as to be in contact with the heat radiating portion 1206. In the present embodiment, when the mobile battery unit 120 is mounted and the sheet 103 is closed, the heat conducting member 130 comes into contact with the heat radiating portion 1206. Thus, the heat generated in mobile battery unit 120 is guided from heat radiating portion 1206 to outside of vehicle body 100 via heat conducting member 130. Therefore, according to the present embodiment, the heat dissipation efficiency of the mobile battery unit 120 can be improved with a relatively simple configuration while improving the usability by using the removable mobile battery unit 120.
　（第２実施形態）
　前述の第１実施形態では車体１００後方に熱交換器１３１を配置した車体構造を例示したが、モバイルバッテリユニット１２０から車体１００外への放熱経路はこの例に限られるものではない。例えば、熱交換器は、車体前方あるいは車体側方に配置されてもよい。即ち、熱伝導部材１３０を用いることで、熱交換器が車体１００の何れの部位に配置されているかに関わらず、モバイルバッテリユニット１２０の多様な放熱態様に対応可能となる。以下、本発明の他の態様として第２実施形態を述べるが、その中で省略される説明は第１実施形態の内容を援用するものとする。 (2nd Embodiment)
In the above-described first embodiment, the vehicle body structure in which the heat exchanger 131 is disposed at the rear of the vehicle body 100 is illustrated, but the heat radiation path from the mobile battery unit 120 to the outside of the vehicle body 100 is not limited to this example. For example, the heat exchanger may be arranged in front of or on the side of the vehicle. That is, by using the heat conducting member 130, it is possible to cope with various heat radiation modes of the mobile battery unit 120 irrespective of where the heat exchanger is disposed on the vehicle body 100. Hereinafter, the second embodiment will be described as another aspect of the present invention, and the description omitted in the second embodiment will use the contents of the first embodiment.
　図４は、第２実施形態に係る電動車両１の車体構造を説明するための模式図を図３（第１実施形態）同様に示す。本実施形態においては、電動車両１は、第１実施形態の熱交換器１３１及び接続部１３２に代替して、熱交換器１４１、流路管１４２ａ、１４２ｂ及び１４２ｃ、並びに、電動ポンプ１４３を備える。 FIG. 4 is a schematic diagram for explaining the vehicle body structure of the electric vehicle 1 according to the second embodiment, similar to FIG. 3 (first embodiment). In the present embodiment, the electric vehicle 1 includes a heat exchanger 141, flow pipes 142a, 142b and 142c, and an electric pump 143 instead of the heat exchanger 131 and the connection part 132 of the first embodiment. .
　熱交換器１４１は、本実施形態では、冷却媒体としての水を冷却するためのラジエータとし、車体１００前方に配置されるものとする。流路管１４２ａ～１４２ｃは冷却媒体の流路となる管である。流路管１４２ａ及び１４２ｂは熱伝導部材１３０と電動ポンプ１４３とを接続するように配置され、それらのうち、流路管１４２ａは熱伝導部材１３０に近い方の側に配置される。流路管１４２ｃは電動ポンプ１４３と熱交換器１４１とを接続するように配置される。図の見易さのため不図示とするが、熱交換器１４１と熱伝導部材１３０とは他の流路管により接続される。電動ポンプ１４３は、冷却媒体を圧送する。 In the present embodiment, the heat exchanger 141 is a radiator for cooling water as a cooling medium, and is disposed in front of the vehicle body 100. The channel pipes 142a to 142c are pipes serving as channels for the cooling medium. The flow pipes 142a and 142b are arranged to connect the heat conduction member 130 and the electric pump 143, and among them, the flow pipe 142a is disposed on the side closer to the heat conduction member 130. The flow pipe 142c is arranged to connect the electric pump 143 and the heat exchanger 141. Although not shown in the figure for the sake of clarity, the heat exchanger 141 and the heat conducting member 130 are connected by another flow pipe. The electric pump 143 pumps the cooling medium.
　このような構成により、熱伝導部材１３０と熱交換器１４１との間で冷却媒体が循環することとなる。即ち、本実施形態においては、冷却媒体は熱伝導部材１３０内をも通過し、換言すると、熱伝導部材１３０は冷却媒体の流路となる流路管（図４において点線で図示）を含む。熱伝導部材１３０は、例えば熱伝導部材１３０内の流路が蛇行した形状となるように設けられてもよく、それにより、モバイルバッテリユニット１２０の熱を効果的に冷却媒体に伝搬させることができる。 構成 With such a configuration, the cooling medium circulates between the heat conducting member 130 and the heat exchanger 141. That is, in the present embodiment, the cooling medium also passes through the inside of the heat conduction member 130, in other words, the heat conduction member 130 includes a flow path pipe (illustrated by a dotted line in FIG. 4) serving as a flow path of the cooling medium. The heat conductive member 130 may be provided, for example, such that a flow path in the heat conductive member 130 has a meandering shape, whereby heat of the mobile battery unit 120 can be effectively transmitted to the cooling medium. .
　第１実施形態同様、熱伝導部材１３０は、開閉自在なシート１０３の下部に設けられ、シート１０３の開閉に従ってシート１０３と共に回動する。よって、流路管１４２ａ～１４２ｃのうち、少なくとも流路管１４２ａは、可撓性の材料で構成され、或いは、屈曲可能／伸縮可能に構成されるとよい。 As in the first embodiment, the heat conducting member 130 is provided below the openable and closable sheet 103, and rotates together with the sheet 103 as the sheet 103 is opened and closed. Therefore, at least the channel pipe 142a among the channel pipes 142a to 142c may be made of a flexible material, or bendable / expandable.
　本実施形態によれば、熱交換器１４１は、車体１００前方に配置されるため、走行時においては前方からの走行風が熱交換器１４１に当たることとなる。よって、モバイルバッテリユニット１２０の熱は、走行風を受ける熱交換器１４１に導かれ、車体１００外に適切に放出されることとなる。よって、本実施形態によっても、第１実施形態同様、モバイルバッテリユニット１２０からの放熱を効果的に実現可能となる。 According to the present embodiment, since the heat exchanger 141 is disposed in front of the vehicle body 100, traveling wind from the front hits the heat exchanger 141 during traveling. Therefore, the heat of the mobile battery unit 120 is guided to the heat exchanger 141 that receives the traveling wind, and is appropriately released to the outside of the vehicle body 100. Therefore, according to the present embodiment, as in the first embodiment, heat radiation from the mobile battery unit 120 can be effectively realized.
　尚、走行の際には、制御装置１２２においても熱が発生しうるため、制御装置１２２は上記冷却媒体の循環経路上に配置されてもよく、それにより、制御装置１２２の放熱をも実現可能となる。また、本実施形態では冷却媒体として水を用いる態様を例示したが、冷却媒体としてオイルが用いられ、熱交換器１４１としてオイルクーラーが用いられてもよい。 In addition, since the control device 122 may generate heat during traveling, the control device 122 may be arranged on the circulation path of the cooling medium, thereby realizing heat dissipation of the control device 122. Becomes Further, in the present embodiment, an example in which water is used as the cooling medium has been described. However, oil may be used as the cooling medium, and an oil cooler may be used as the heat exchanger 141.
　（第３実施形態）
　前述の第１実施形態では、モバイルバッテリユニット１２０の放熱部１２０６が筐体１２００上面において露出した態様を例示したが、この例に限られるものではなく、モバイルバッテリユニット１２０内の熱を筐体１２００外に取り出し可能となっていればよい。即ち、放熱部は、筐体１２００外面の何れにおいて露出して設けられてもよく、例えば、筐体１２００の下面（底面）、側面、前面あるいは背面において露出して設けられてもよい。以下、本発明の他の態様として第３実施形態を述べるが、その中で省略される説明は第１～第２実施形態の内容を援用するものとする。 (Third embodiment)
In the above-described first embodiment, the mode in which the heat radiating portion 1206 of the mobile battery unit 120 is exposed on the upper surface of the housing 1200 has been exemplified. However, the present invention is not limited to this example. What is necessary is just to be able to take out outside. That is, the heat radiating portion may be provided on any of the outer surfaces of the housing 1200 so as to be exposed. For example, the heat radiating portion may be provided on the lower surface (bottom surface), the side surface, the front surface, or the rear surface of the housing 1200. Hereinafter, a third embodiment will be described as another aspect of the present invention, and the description omitted in the third embodiment will use the contents of the first and second embodiments.
　図５は、第３実施形態に係る電動車両１の車体構造を説明するための模式図を図３（第１実施形態）同様に示す。図６は、本実施形態で車体１００に装着されるモバイルバッテリユニット（区別のため「モバイルバッテリユニット１２０’」とする。）の構成を示す正面図である。本実施形態では、第１実施形態の熱伝導部材１３０に代替して熱伝導部材１３０’が車体１００下方部に配置され、この熱伝導部材１３０’上にモバイルバッテリユニット１２０’が載置されて装着される。 FIG. 5 is a schematic diagram for explaining the vehicle body structure of the electric vehicle 1 according to the third embodiment, similarly to FIG. 3 (first embodiment). FIG. 6 is a front view showing a configuration of a mobile battery unit (hereinafter, referred to as “mobile battery unit 120 ′”) mounted on the vehicle body 100 in the present embodiment. In the present embodiment, a heat conductive member 130 'is disposed below the vehicle body 100 in place of the heat conductive member 130 of the first embodiment, and the mobile battery unit 120' is mounted on the heat conductive member 130 '. Be attached.
　また、本実施形態では、電動車両１は、熱交換器１４１、流路管１４２ｃ及び１４２ｄ、並びに、電動ポンプ１４３を備える。熱交換器１４１、流路管１４２ｃおよび電動ポンプ１４３については第２実施形態同様とし、流路管１４２ｄは熱伝導部材１３０’と電動ポンプ１４３とを接続するように配置される。このような構成により、熱伝導部材１３０’と熱交換器１４１との間で冷却媒体が循環する。 In addition, in this embodiment, the electric vehicle 1 includes the heat exchanger 141, the flow pipes 142c and 142d, and the electric pump 143. The heat exchanger 141, the flow pipe 142c, and the electric pump 143 are the same as in the second embodiment, and the flow pipe 142d is arranged to connect the heat conducting member 130 'and the electric pump 143. With such a configuration, the cooling medium circulates between the heat conducting member 130 'and the heat exchanger 141.
　モバイルバッテリユニット１２０’は、図６に示されるように、第１実施形態の放熱部１２０６に代替して放熱部１２０６’を含み、更に延設部１２０７ａ及び１２０７ｂを含む。放熱部１２０６’は、筐体１２００下面において露出して設けられる。延設部１２０７ａは、筐体１２００上方部においてヒートパイプ部１２０５に接続される。具体的には、ヒートパイプ部１２０５は、筐体１２００上方部において筐体１２００上面に沿って延設されており（第１実施形態同様）、この部分において延設部１２０７ａに内包される。延設部１２０７ｂは、延設部１２０７ａから、筐体１２００側方部を通って筐体１２００下方部まで延設され、放熱部１２０６’に接続される。放熱部１２０６’並びに延設部１２０７ａ及び１２０７ｂは好適には一体成形され、それらには熱伝導率の比較的高い金属（例えば鉄、アルミニウム、それらの合金等）が用いられる。 As shown in FIG. 6, the mobile battery unit 120 ’includes a heat radiating portion 1206 ′ instead of the heat radiating portion 1206 of the first embodiment, and further includes extended portions 1207a and 1207b. The heat radiating portion 1206 'is provided to be exposed on the lower surface of the housing 1200. The extension 1207a is connected to the heat pipe 1205 in the upper part of the housing 1200. Specifically, the heat pipe portion 1205 extends along the upper surface of the housing 1200 at the upper portion of the housing 1200 (similar to the first embodiment), and is included in the extending portion 1207a at this portion. The extending portion 1207b extends from the extending portion 1207a to a lower portion of the housing 1200 through a side portion of the housing 1200, and is connected to the heat radiating portion 1206 '. The heat radiating portion 1206 'and the extending portions 1207a and 1207b are preferably integrally formed, and are made of a metal having a relatively high thermal conductivity (e.g., iron, aluminum, an alloy thereof, etc.).
　このようなモバイルバッテリユニット１２０’の構造によれば、バッテリ部１２０１の電力を用いたことにより発生した熱は、ヒートパイプ部１２０５並びに延設部１２０７ａ及び１２０７ｂを介して、放熱部１２０６’に集められることとなる。 According to the structure of the mobile battery unit 120 ′, heat generated by using the power of the battery unit 1201 is collected in the heat radiating unit 1206 ′ via the heat pipe unit 1205 and the extension units 1207a and 1207b. Will be done.
　このようなモバイルバッテリユニット１２０’が装着された場合、車体１００下方部に配置された熱伝導部材１３０’は、その上にモバイルバッテリユニット１２０’が載置されて放熱部１２０６’と当接する。そのため、モバイルバッテリユニット１２０’で生じた熱は、放熱部１２０６’から熱伝導部材１３０’を介して車体１００外に向かって導かれることとなる。よって、本実施形態によっても、第１～第２実施形態同様、モバイルバッテリユニット１２０’の放熱効率を比較的簡素な構成で向上可能となる。 When the mobile battery unit 120 'is mounted, the heat conducting member 130' disposed on the lower part of the vehicle body 100 has the mobile battery unit 120 'mounted thereon and comes into contact with the heat radiating portion 1206'.
