　本出願は、２０１７年８月２４日に出願された日本特許出願番号２０１７－１６１２６０号に基づくもので、ここにその記載内容が参照により組み入れられる。 This application is based on Japanese Patent Application No. 2017-161260 filed on Aug. 24, 2017, the contents of which are incorporated herein by reference.
　本開示は、電池の温度を調節する電池温調装置に関するものである。 The present disclosure relates to a battery temperature control device that adjusts the temperature of a battery.
　従来、車両または定置設備等に設置された電池を冷却または暖機する技術が検討されている。 Conventionally, a technique for cooling or warming up a battery installed in a vehicle or stationary equipment or the like has been considered.
　特許文献１に記載の電池温調装置は、サーモサイフォン回路により車両に設置された電池の温度を調整するものである。この電池温調装置は、電池に固定された電池用熱交換器と、その電池用熱交換器の上方に設けられた凝縮器とが２本の配管により接続され、その中に作動流体としての熱媒体が封入された構成である。 The battery temperature control device described in Patent Document 1 adjusts the temperature of a battery installed in a vehicle by a thermosiphon circuit. In this battery temperature control apparatus, a heat exchanger for a battery fixed to a battery and a condenser provided above the heat exchanger for a battery are connected by two pipes, in which a working fluid is provided. The heat medium is sealed.
　この電池温調装置は、電池が発熱すると、電池用熱交換器の内側の熱媒体が電池から吸熱して蒸発し、一方の配管を通って凝縮器に流入する。凝縮器は、その気相の熱媒体を、外部の熱媒体との熱交換により凝縮させる。凝縮器で凝縮した液相の熱媒体は、自重により他方の配管内を流下して電池用熱交換器に流入する。このように、この電池温調装置は、サーモサイフォン回路に熱媒体を自然循環させ、電池用熱交換器の内側で熱媒体が沸騰蒸発するときの気化熱により電池を冷却するものである。 In this battery temperature control device, when the battery generates heat, the heat medium inside the battery heat exchanger absorbs heat from the battery, evaporates, and flows into the condenser through one pipe. The condenser condenses the heat medium in the gas phase by heat exchange with an external heat medium. The heat medium of the liquid phase condensed by the condenser flows down the inside of the other pipe by its own weight and flows into the battery heat exchanger. As described above, this battery temperature control device naturally circulates the heat medium in the thermosyphon circuit, and cools the battery by heat of vaporization when the heat medium is boiled and evaporated inside the heat exchanger for the battery.
　また、この電池温調装置は、電池用熱交換器の内側に、熱媒体を加熱することの可能な加熱部を備えている。電池温調装置は、電池の暖機時に、加熱部により熱媒体を加熱する。加熱された熱媒体は、電池用熱交換器の内側で気化した後、電池に放熱することで、凝縮する。このように、電池温調装置は、電池用熱交換器の内側での熱媒体の相変化により電池を加熱することも可能である。 Moreover, this battery temperature control apparatus is equipped with the heating part which can heat a heat carrier inside the heat exchanger for batteries. The battery temperature control device heats the heat medium by the heating unit when the battery is warmed up. The heated heat medium evaporates inside the battery heat exchanger and then condenses by radiating heat to the battery. As described above, the battery temperature control device can also heat the battery by phase change of the heat medium inside the battery heat exchanger.
特許第５９４２９４３号公報Patent No. 5942943 gazette
　発明者らは、特許文献１のような車両等に搭載される電池温調装置に関し、次のような課題を見出した。すなわち、図１７に示すように、車両等に設置される大型の電池２は、複数の電池セル３が組み合わされた電池モジュール４が複数格納された電池パック５として、車両の座席下またはトランクルームの下などに搭載される。その電池パック５に格納される電池モジュール４に対し、電池温調装置７００が備える電池用熱交換器７１０は、図示していない粘着性の放熱シート等により接着される。電池用熱交換器７１０が接着された複数の電池モジュール４は、隙間が殆どない状態で電池パック５のケース内に格納される。一方、電池温調装置７００が備える凝縮器７７０、７８０は、車両のエンジンルームなどに配置される。そのため、電池用熱交換器７１０と凝縮器７７０、７８０とを接続する配管７２０は、車体の各部を複雑に取り回されることとなる。このような構成において、車両等に電池温調装置７００を設置する際、電池パック５に格納された電池用熱交換器７１０と、車体の各部を取り回された配管７２０とをねじ７９０等により接続する作業が必要になる。そして、そのように構成されたサーモサイフォン回路を真空引きし、そこに熱媒体を充填する作業が必要となる。 The inventors have found the following problems regarding the battery temperature control device mounted on a vehicle as described in Patent Document 1 or the like. That is, as shown in FIG. 17, a large battery 2 installed in a vehicle or the like is used as a battery pack 5 in which a plurality of battery modules 4 in which a plurality of battery cells 3 are combined is stored. It is mounted at the bottom etc. The battery heat exchanger 710 provided in the battery temperature adjustment device 700 is adhered to the battery module 4 stored in the battery pack 5 by an adhesive heat-dissipation sheet or the like (not shown). The plurality of battery modules 4 to which the battery heat exchanger 710 is adhered are stored in the case of the battery pack 5 with almost no gap. On the other hand, the condensers 770 and 780 included in the battery temperature control device 700 are disposed in the engine room of the vehicle or the like. Therefore, the piping 720 connecting the battery heat exchanger 710 and the condensers 770 and 780 will be complicatedly routed around each part of the vehicle body. In such a configuration, when installing the battery temperature control device 700 in a vehicle or the like, the battery heat exchanger 710 stored in the battery pack 5 and the piping 720 around each part of the vehicle body are separated by the screw 790 or the like. It is necessary to work to connect. Then, it is necessary to evacuate the thermosiphon circuit configured as described above and fill the heat medium there.
　また、車両等に設置された電池２のメンテナンスを行う際には、車両から電池パック５を取り外した後に、電池セル３の交換または点検作業を行わなければならない。具体的に、電池セル３の交換または点検前には、サーモサイフォン回路から熱媒体の抜き取り作業→電池用熱交換器７１０と配管７２０との分解作業→車体から電池パック５の取り外し作業→電池用熱交換器７１０と電池モジュール４との分離作業などが必要となる。また、電池セル３の交換または点検後には、電池用熱交換器７１０と電池モジュール４との接続作業→車体への電池パック５の取り付け作業→電池用熱交換器７１０と配管７２０との接続作業→サーモサイフォン回路の真空引き作業→熱媒体の充填作業などが必要となる。したがって、車両等への電池温調装置７００の設置、および、車両等に設置された電池２のメンテナンスには、非常に大きな時間と手間を要する。 Moreover, when performing maintenance of the battery 2 installed in a vehicle etc., after removing the battery pack 5 from a vehicle, it is necessary to perform replacement | exchange of the battery cell 3, or inspection work. Specifically, before replacement or inspection of the battery cell 3, removal of the heat medium from the thermosyphon circuit → disassembly of the battery heat exchanger 710 and the pipe 720 → removal of the battery pack 5 from the vehicle body → for the battery A separation operation between the heat exchanger 710 and the battery module 4 is required. In addition, after replacement or inspection of battery cell 3, connection work of battery heat exchanger 710 and battery module 4 work of attachment of battery pack 5 to vehicle body work of connection of battery heat exchanger 710 and piping 720 → It is necessary to evacuate the thermosyphon circuit → fill the heat medium. Therefore, installation of the battery temperature control apparatus 700 in a vehicle etc., and maintenance of the battery 2 installed in the vehicle etc. require very big time and effort.
　なお、上記課題では、電池が車両に搭載される場合について説明したが、本開示の電池温調装置が温度調整の対象とする電池は、車両に搭載されるものに限らない。例えば、定置設備等に設置される大型の電池についても、組付け時およびメンテナンス時には、同様の課題がある。したがって、本開示の電池温調装置は、車両に搭載される電池に限らず、定置設備等に設置される電池も対象としている。 In addition, although the case where a battery is mounted in a vehicle was demonstrated by the said subject, the battery which the battery temperature control apparatus of this indication makes temperature adjustment object is not restricted to what is mounted in a vehicle. For example, even with a large battery installed in stationary equipment and the like, there are similar problems at the time of assembly and maintenance. Therefore, the battery temperature control device of the present disclosure is not limited to the battery mounted on the vehicle, but also covers the battery installed in stationary equipment and the like.
　本開示は、組付け性およびメンテナンス性を高めることの可能な電池温調装置を提供することを目的とする。 An object of the present disclosure is to provide a battery temperature control device capable of enhancing assemblability and maintainability.
　本開示の１つの観点によれば、

　接続熱交換器に対し着脱可能に構成され、第１熱接触面に直接接触または熱伝導部材を介して間接的に熱接触する第２熱接触面を有し、第１熱接触面と第２熱接触面とが熱接触した状態で接続熱交換器を流れる熱媒体を冷却または加熱することの可能な熱源部と、を備える。 According to one aspect of the present disclosure,

A battery heat exchanger that exchanges heat between the battery and the heat medium;
Piping connected to the battery heat exchanger and through which the heat medium flows;
A connection heat exchanger configured to flow a heat medium through the battery heat exchanger and the piping and having a first thermal contact surface formed along the direction of gravity;

　これによれば、車両または定置設備等の製造時において、電池に電池用熱交換器、配管および接続熱交換器を設置する作業と、車両または定置設備等に熱源部を設置する作業とを別工程で行うことが可能である。そして、接続熱交換器の第１熱接触面と熱源部の第２熱接触面とを直接接触または熱伝導部材を介して間接的に熱接触させることで、１つの熱回路としての電池温調装置を構成することが可能である。 According to this, at the time of production of a vehicle or stationary equipment, the work of installing the battery heat exchanger, piping and connection heat exchanger in the battery and the work of installing the heat source unit in the vehicle or stationary equipment etc. It is possible to carry out in the process. Then, the first thermal contact surface of the connection heat exchanger and the second thermal contact surface of the heat source unit are brought into direct thermal contact or indirect thermal contact via the thermal conduction member, thereby adjusting the battery temperature as one thermal circuit. It is possible to configure the device.
　また、車両または定置設備等に設置された電池用熱交換器または電池のメンテナンスを行う際、接続熱交換器と熱源部とを分離すれば、電池と電池用熱交換器と配管と接続熱交換器を一緒に、車両または定置設備等から取り外すことが可能である。そのため、車両または定置設備等における熱源部の配管の取り回しなどが複雑な構成である場合でも、電池用熱交換器等に対する熱媒体の抜き取り作業および再充填作業を行うことなく、電池用熱交換器または電池のメンテナンスを短時間で容易に行うことが可能である。したがって、この電池温調装置は、車両または定置設備等に対する電池温調装置および電池の組付け性と、使用時における電池温調装置および電池のメンテナンス性を高めることができる。 In addition, when maintaining the battery heat exchanger or the battery installed in the vehicle or stationary equipment, if the connection heat exchanger and the heat source unit are separated, the battery, the battery heat exchanger, the piping, and the connection heat exchange are performed. The devices can be removed together from the vehicle or stationary equipment etc. Therefore, even if the arrangement of the piping of the heat source unit in a vehicle or stationary equipment etc. has a complicated configuration, the heat exchanger for battery can be carried out without performing the work of extracting the heat medium to the heat exchanger for battery etc. Alternatively, battery maintenance can be easily performed in a short time. Therefore, this battery temperature control device can enhance the assemblability of the battery temperature control device and the battery with respect to the vehicle or stationary equipment and the like, and the maintainability of the battery temperature control device and the battery at the time of use.

　以下、本開示の実施形態について図を参照しつつ説明する。なお、以下の各実施形態相互において、互いに同一もしくは均等である部分には、同一符号を付して説明を行う。 Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In the following embodiments, parts that are the same as or equivalent to each other will be described with the same reference numerals.
　（第１実施形態）
　第１実施形態について、図１～図３を参照して説明する。第１実施形態の電池温調装置１は、電気自動車やハイブリッド車などの電動車両（以下、単に「車両」という）に搭載されるものである。第１実施形態の電池温調装置１は、車両に搭載される二次電池（以下、「電池２」という）を冷却する冷却装置として機能する。 First Embodiment
The first embodiment will be described with reference to FIGS. 1 to 3. The battery temperature control device 1 of the first embodiment is mounted on an electric vehicle such as an electric vehicle or a hybrid vehicle (hereinafter, simply referred to as a “vehicle”). The battery temperature control device 1 of the first embodiment functions as a cooling device for cooling a secondary battery (hereinafter referred to as “battery 2”) mounted on a vehicle.
　まず、電池温調装置１が冷却する対象機器としての電池２について説明する。車両に設置される大型の電池２は、複数の電池セル３が組み合わされた電池モジュール４が複数格納された電池パック５（すなわち蓄電装置）として、車両の座席下またはトランクルームの下などに搭載される。電池２に蓄えた電力は、インバータなどを介して車両走行用モータに供給される。電池２は車両走行中など充放電時に自己発熱する。電池２は高温になると、十分な機能を発揮できないだけでなく、劣化や破損を招くので、電池２を一定温度以下に維持するための冷却装置が必要となる。 First, the battery 2 as a target device to be cooled by the battery temperature control device 1 will be described. A large battery 2 installed in a vehicle is mounted under a seat of a vehicle or under a trunk room as a battery pack 5 (i.e., a storage device) in which a plurality of battery modules 4 in which a plurality of battery cells 3 are combined is stored. Ru. The power stored in the battery 2 is supplied to the vehicle drive motor via an inverter or the like. The battery 2 generates heat when charging and discharging, for example, while the vehicle is traveling. When the temperature of the battery 2 becomes high, it not only can not exert sufficient functions but also causes deterioration or breakage, so a cooling device for maintaining the battery 2 at a certain temperature or lower is required.
　また、夏季などの外気温が高い季節では、車両走行中だけでなく、駐車放置中などにも電池２の温度は上昇する。また、電池２は車両の床下やトランクルーム下などに配置されることが多く、電池２に与えられる単位時間当たりの熱量は小さいものの、長時間の放置により電池２の温度は徐々に上昇する。電池２を高温状態で放置すると電池２の寿命が短くなるので、車両の放置中も電池２を冷却するなど電池２の温度を低温に維持することが望まれている。 In addition, in a season where the outside air temperature is high such as summer, the temperature of the battery 2 rises not only while the vehicle is traveling but also while it is parked and the like. Also, the battery 2 is often disposed under the floor of the vehicle, under the trunk room, etc., and although the amount of heat per unit time given to the battery 2 is small, the temperature of the battery 2 gradually rises by leaving for a long time. When the battery 2 is left in a high temperature state, the life of the battery 2 is shortened. Therefore, it is desirable to maintain the temperature of the battery 2 at a low temperature, such as cooling the battery 2 while the vehicle is left.
　さらに、電池２は、複数の電池セル３を含む電池モジュール４として構成されているが、各電池セル３の温度にばらつきがあると電池セル３の劣化に偏りが生じ、電池２の蓄電性能が低下してしまう。これは、最も劣化した電池セル３の特性に合わせて蓄電装置の入出力特性が決まることによる。そのため、長期間にわたって電池２に所望の性能を発揮させるためには、複数の電池セル３の相互間の温度ばらつきを低減させる均温化が重要となる。 Furthermore, although battery 2 is configured as battery module 4 including a plurality of battery cells 3, if there is variation in the temperature of each battery cell 3, bias occurs in the deterioration of battery cell 3, and the storage performance of battery 2 It will decrease. This is because the input / output characteristics of the power storage device are determined in accordance with the characteristics of the battery cell 3 that has deteriorated the most. Therefore, in order to cause the battery 2 to exhibit desired performance over a long period of time, it is important to make the temperature uniform to reduce the temperature variation among the plurality of battery cells 3.
　また、一般に、電池２を冷却する他の冷却装置として、ブロワによる送風方式が採用されることがある。しかし、ブロワは車室内の空気を送風するだけなので、冷却能力は低い。また、ブロワによる送風では空気の顕熱で電池２を冷却するので、空気流れの上流と下流との間で温度差が大きくなり、複数の電池セル３同士の温度ばらつきを十分に抑制できない。このような背景から、第１実施形態の電池温調装置１は、熱媒体の自然循環によって電池２の温度を調整するサーモサイフォン方式を採用している。 Also, in general, as another cooling device for cooling the battery 2, a blower system using a blower may be adopted. However, since the blower only blows the air in the passenger compartment, the cooling capacity is low. Further, since the battery 2 is cooled by the sensible heat of the air in the blowing by the blower, the temperature difference between the upstream and the downstream of the air flow becomes large, and the temperature variation between the plurality of battery cells 3 can not be sufficiently suppressed. From such a background, the battery temperature control device 1 of the first embodiment adopts a thermo-siphon system in which the temperature of the battery 2 is adjusted by natural circulation of the heat medium.
　次に、電池温調装置１の構成について説明する。電池温調装置１は、電池用熱交換器１０と配管２０と接続熱交換器３０と熱源部４０を備えている。第１実施形態の電池温調装置１が備える電池用熱交換器１０と配管２０と接続熱交換器３０は、第１のサーモサイフォン回路１００を構成している。第１のサーモサイフォン回路１００は、電池パック５側に設けられている。以下の説明では、第１のサーモサイフォン回路１００を構成する配管２０を第１配管２０と称し、第１のサーモサイフォン回路１００を構成する接続熱交換器３０を第１接続熱交換器３０と称する。また、第１のサーモサイフォン回路１００を流れる熱媒体を第１熱媒体と称する。第１熱媒体には、例えば、ＨＦＯ－１２３４ｙｆまたはＨＦＣ－１３４ａなどのフロン系の作動流体が用いられる。 Next, the configuration of the battery temperature control device 1 will be described. The battery temperature adjustment device 1 includes a battery heat exchanger 10, a pipe 20, a connection heat exchanger 30, and a heat source unit 40. The battery heat exchanger 10, the pipe 20, and the connection heat exchanger 30 included in the battery temperature control device 1 according to the first embodiment constitute a first thermosyphon circuit 100. The first thermosiphon circuit 100 is provided on the battery pack 5 side. In the following description, the pipe 20 constituting the first thermosiphon circuit 100 is referred to as a first pipe 20, and the connection heat exchanger 30 constituting the first thermosiphon circuit 100 is referred to as a first connection heat exchanger 30. . Further, the heat medium flowing through the first thermosiphon circuit 100 is referred to as a first heat medium. For example, a fluorocarbon working fluid such as HFO-1234yf or HFC-134a is used as the first heat medium.
　電池用熱交換器１０は、上ヘッダタンク１１、下ヘッダタンク１２、および、その上ヘッダタンク１１と下ヘッダタンク１２とを連通する複数のチューブ１３を有している。第１のサーモサイフォン回路１００を循環する第１熱媒体の液面ＦＬ１は、電池用熱交換器１０のチューブ１３の内側の流路の途中に位置している。電池用熱交換器１０は、電池モジュール４に対し、粘着性を有する放熱シート等により接着されている。そのため、電池用熱交換器１０は、電池２と第１熱媒体との熱交換を行うことが可能である。なお、電池用熱交換器１０が接着された複数の電池モジュール４は、隙間が殆どない状態で電池パック５のケース内に格納される。 The battery heat exchanger 10 includes an upper header tank 11, a lower header tank 12, and a plurality of tubes 13 communicating the upper header tank 11 with the lower header tank 12. The liquid surface FL1 of the first heat medium circulating in the first thermosyphon circuit 100 is located in the middle of the flow path inside the tube 13 of the battery heat exchanger 10. The battery heat exchanger 10 is bonded to the battery module 4 by a heat-radiating sheet or the like having adhesiveness. Therefore, the battery heat exchanger 10 can perform heat exchange between the battery 2 and the first heat medium. The plurality of battery modules 4 to which the battery heat exchanger 10 is adhered are stored in the case of the battery pack 5 with almost no gap.
　第１接続熱交換器３０も、上ヘッダタンク３１、下ヘッダタンク３２、および、その上ヘッダタンク３１と下ヘッダタンク３２とを連通する複数のチューブ３３を有している。第１のサーモサイフォン回路１００を循環する第１熱媒体の液面ＦＬ２は、第１接続熱交換器３０のチューブ３３の内側の流路の途中に位置している。第１接続熱交換器３０は、第１熱接触面３５を有している。図１および図２では、第１熱接触面３５の範囲を分かりやすく示すため、断面ではないが、第１熱接触面３５にハッチングを付している。第１熱接触面３５は、重力方向に沿うように形成されている。なお、「重力方向に沿う」とは、第１熱接触面３５が重力方向に平行に形成されていることに加え、第１熱接触面３５が重力方向に対して３０°程度傾いている状態も含むことを意味している。第１熱接触面３５には、後述する熱源部４０が有する第２熱接触面５５が、直接接触するか、または、熱伝導部材４１を介して間接的に熱接触する。 The first connection heat exchanger 30 also has an upper header tank 31, a lower header tank 32, and a plurality of tubes 33 communicating the upper header tank 31 and the lower header tank 32 with each other. The liquid surface FL2 of the first heat medium circulating in the first thermosyphon circuit 100 is located in the middle of the flow path inside the tube 33 of the first connection heat exchanger 30. The first connection heat exchanger 30 has a first thermal contact surface 35. In FIG. 1 and FIG. 2, in order to show the range of the 1st thermal contact surface 35 intelligibly, although it is not a cross section, the 1st thermal contact surface 35 is hatched. The first thermal contact surface 35 is formed along the direction of gravity. Note that “along the direction of gravity” means that the first thermal contact surface 35 is inclined by about 30 ° with respect to the direction of gravity, in addition to the fact that the first thermal contact surface 35 is formed parallel to the direction of gravity. Is also meant to be included. The first thermal contact surface 35 is in direct contact with the second thermal contact surface 55 of the heat source unit 40 described later, or indirectly in thermal contact via the thermal conduction member 41.
　第１配管２０は、第１液体通路２１および第１気体通路２２を有している。第１液体通路２１は、電池用熱交換器１０の下ヘッダタンク１２に設けられた流出入口１２１と、第１接続熱交換器３０の下ヘッダタンク３２に設けられた流出入口３２１とを接続している。すなわち、第１液体通路２１は、電池用熱交換器１０のうちで熱媒体の液面ＦＬ１より下側に設けられた流出入口１２１と、第１接続熱交換器３０のうちで熱媒体の液面ＦＬ２より下側に設けられた流出入口３２１とを接続している。第１気体通路２２は、電池用熱交換器１０の上ヘッダタンク１１に設けられた流出入口１１１と、第１接続熱交換器３０の上ヘッダタンク３１に設けられた流出入口３１１とを接続している。すなわち、第１気体通路２２は、電池用熱交換器１０のうちで熱媒体の液面ＦＬ１より上側に設けられた流出入口１１１と、第１接続熱交換器３０のうちで熱媒体の液面ＦＬ２より上側に設けられた流出入口３１１とを接続している。これにより、電池用熱交換器１０、第１接続熱交換器３０、第１液体通路２１および第１気体通路２２は、第１熱媒体が循環する第１のサーモサイフォン回路１００を構成する。第１のサーモサイフォン回路１００は、電池２と共に車体に対して着脱可能に設けられている。 The first pipe 20 has a first liquid passage 21 and a first gas passage 22. The first liquid passage 21 connects the outlet / inlet 121 provided in the lower header tank 12 of the battery heat exchanger 10 with the outlet / inlet 321 provided in the lower header tank 32 of the first connection heat exchanger 30. ing. That is, the first liquid passage 21 is the liquid inlet / outlet 121 provided below the liquid surface FL1 of the heat medium in the battery heat exchanger 10, and the liquid of the heat medium in the first connection heat exchanger 30. It connects with the outflow inlet 321 provided below the plane FL2. The first gas passage 22 connects the outlet / inlet 111 provided in the upper header tank 11 of the battery heat exchanger 10 and the outlet / inlet 311 provided in the upper header tank 31 of the first connection heat exchanger 30. ing. That is, the first gas passage 22 is provided at the outflow / inflow port 111 provided above the liquid surface FL1 of the heat medium in the battery heat exchanger 10, and the liquid surface of the heat medium in the first connection heat exchanger 30. It connects with the outflow inlet 311 provided above FL2. Thus, the battery heat exchanger 10, the first connection heat exchanger 30, the first liquid passage 21 and the first gas passage 22 constitute a first thermosiphon circuit 100 in which the first heat medium circulates. The first thermosiphon circuit 100 is detachably provided to the vehicle body together with the battery 2.
　一方、第１実施形態の電池温調装置１が備える熱源部４０は、第２接続熱交換器５０、第２配管６０および放熱器７０、８０を有している。熱源部４０が有する第２接続熱交換器５０と第２配管６０と放熱器７０、８０は、第２のサーモサイフォン回路２００を構成している。第２のサーモサイフォン回路２００は、車体の各部に亘って設けられている。以下の説明では、第２のサーモサイフォン回路２００を流れる熱媒体を第２熱媒体と称する。第１のサーモサイフォン回路１００を流れる第１熱媒体と、第２のサーモサイフォン回路２００を流れる第２熱媒体とは、互いに混ざり合うことがないので、同一の熱媒体であってもよく、または、異なる熱媒体であってもよい。 On the other hand, the heat source unit 40 provided in the battery temperature adjustment device 1 of the first embodiment includes the second connection heat exchanger 50, the second pipe 60, and the radiators 70, 80. The second connection heat exchanger 50, the second pipe 60, and the radiators 70, 80 of the heat source unit 40 constitute a second thermosiphon circuit 200. The second thermosiphon circuit 200 is provided across each part of the vehicle body. In the following description, the heat medium flowing through the second thermosiphon circuit 200 is referred to as a second heat medium. The first heat medium flowing through the first thermosiphon circuit 100 and the second heat medium flowing through the second thermosiphon circuit 200 may be the same heat medium because they do not mix with each other, or And may be different heat transfer media.
　第２接続熱交換器５０も、上ヘッダタンク５１、下ヘッダタンク５２、および、その上ヘッダタンク５１と下ヘッダタンク５２とを連通する複数のチューブ５３を有している。第２のサーモサイフォン回路２００を循環する第２熱媒体の液面ＦＬ３は、第２接続熱交換器５０のチューブ５３の内側の流路の途中に位置している。第２接続熱交換器５０は、第２熱接触面５５を有している。第２熱接触面５５も、重力方向に沿うように形成されている。上述した第１接続熱交換器３０と第２接続熱交換器５０とは、着脱可能に構成されている。具体的には、第１接続熱交換器３０と第２接続熱交換器５０とは、例えば、ねじ又はクランプ等の固定部材により着脱可能に固定することが可能な構成である。すなわち、車両に電池温調装置１を設置する際、または、車両に設置された電池２のメンテナンスを行う際に、第１接続熱交換器３０と第２接続熱交換器５０とは、容易に着脱可能な構成である。 The second connection heat exchanger 50 also has an upper header tank 51, a lower header tank 52, and a plurality of tubes 53 communicating the upper header tank 51 with the lower header tank 52. The liquid surface FL3 of the second heat medium circulating in the second thermosiphon circuit 200 is located midway in the flow path inside the tube 53 of the second connection heat exchanger 50. The second connection heat exchanger 50 has a second thermal contact surface 55. The second thermal contact surface 55 is also formed along the direction of gravity. The first connection heat exchanger 30 and the second connection heat exchanger 50 described above are configured to be removable. Specifically, the first connection heat exchanger 30 and the second connection heat exchanger 50 are configured to be detachably fixed, for example, by a fixing member such as a screw or a clamp. That is, when installing the battery temperature control device 1 in a vehicle, or when performing maintenance of the battery 2 installed in the vehicle, the first connection heat exchanger 30 and the second connection heat exchanger 50 can easily be used. It is a removable configuration.
　第１接続熱交換器３０と第２接続熱交換器５０とが固定されるとき、第１接続熱交換器３０が有する第１熱接触面３５と第２接続熱交換器５０が有する第２熱接触面５５とは、直接接触するか、または、熱伝導部材４１を介して間接的に熱接触する。これにより、第１のサーモサイフォン回路１００を流れる第１熱媒体と、第２のサーモサイフォン回路２００を流れる第２熱媒体とは、第１熱接触面３５と第２熱接触面５５を介して熱交換が行われる。すなわち、この電池温調装置１は、第１のサーモサイフォン回路１００と第２のサーモサイフォン回路２００との間の熱移動が可能な１つの熱回路を構成するものである。 When the first connection heat exchanger 30 and the second connection heat exchanger 50 are fixed, the first heat contact surface 35 of the first connection heat exchanger 30 and the second heat of the second connection heat exchanger 50 are provided. The contact surface 55 is in direct contact or in indirect thermal contact via the heat conducting member 41. As a result, the first heat medium flowing through the first thermosiphon circuit 100 and the second heat medium flowing through the second thermosiphon circuit 200 pass through the first thermal contact surface 35 and the second thermal contact surface 55. Heat exchange takes place. That is, the battery temperature control device 1 constitutes one thermal circuit capable of heat transfer between the first thermosiphon circuit 100 and the second thermosiphon circuit 200.
　放熱器７０、８０は、空気放熱器７０、および、冷媒放熱器８０などから構成されている。空気放熱器７０、および、冷媒放熱器８０は、車両のエンジンルームなどに設けられている。空気放熱器７０は、第２のサーモサイフォン回路２００を循環する第２熱媒体と、空気放熱器７０を通過する外気との熱交換を行うことで、第２熱媒体の熱を外気に放熱させる熱交換器である。空気放熱器７０を通過する外気は、外部の熱媒体の一例である。 The radiators 70 and 80 are composed of an air radiator 70, a refrigerant radiator 80, and the like. The air radiator 70 and the refrigerant radiator 80 are provided in, for example, an engine room of a vehicle. The air radiator 70 performs heat exchange between the second heat medium circulating in the second thermosiphon circuit 200 and the outside air passing through the air radiator 70 to dissipate the heat of the second heat medium to the outside air. It is a heat exchanger. The outside air passing through the air radiator 70 is an example of an external heat medium.
　冷媒放熱器８０は、第２のサーモサイフォン回路２００を循環する第２熱媒体と、冷凍サイクル８５の蒸発器８６を流れる低温低圧の冷媒との熱交換を行うことで、第２熱媒体の熱を冷凍サイクル８５の冷媒に放熱させる熱交換器である。冷凍サイクル８５の冷媒も、外部の熱媒体の一例である。なお、空気放熱器７０と冷媒放熱器８０は、電池２の発熱状態または車両の走行状態などに応じて使い分けることが可能である。また、冷媒放熱器８０に代えて、図示していない液回路を流れる冷却水等の液体と熱媒体との熱交換を行う液冷放熱器により放熱器を構成してもよい。その場合、冷却水等の液体も、外部の熱媒体の一例である。 The refrigerant radiator 80 performs heat exchange between the second heat medium circulating in the second thermosyphon circuit 200 and the low-temperature low-pressure refrigerant flowing through the evaporator 86 of the refrigeration cycle 85 to obtain the heat medium of the second heat medium. Is radiated to the refrigerant of the refrigeration cycle 85. The refrigerant of the refrigeration cycle 85 is also an example of the external heat medium. The air radiator 70 and the refrigerant radiator 80 can be selectively used depending on the heat generation state of the battery 2 or the traveling state of the vehicle. Further, instead of the refrigerant radiator 80, the radiator may be configured by a liquid-cooling radiator that performs heat exchange between a heat medium and a liquid such as cooling water flowing in a liquid circuit (not shown). In that case, a liquid such as cooling water is also an example of the external heat medium.
　第２配管６０は、第２液体通路６１および第２気体通路６２を有している。第２液体通路６１は、第２接続熱交換器５０の下ヘッダタンク５２に設けられた流出入口５２１と、空気放熱器７０の下側に設けられた流出入口７１と、冷媒放熱器８０の下側に設けられた流出入口８１とを接続している。第２気体通路６２は、第２接続熱交換器５０の上ヘッダタンク５１に設けられた流出入口５１１と、空気放熱器７０の上側に設けられた流出入口７２と、冷媒放熱器８０の上側に設けられた流出入口８２とを接続している。すなわち、第２配管６０は、電池パック５が設けられた車両の座席下またはトランクルーム下と、空気放熱器７０および冷媒放熱器８０が設けられるエンジンルーム内との間で、車体の各部を複雑に取り回されることになる。このように、第２接続熱交換器５０、放熱器７０、８０、第２液体通路６１および第２気体通路６２は、第２熱媒体が循環する第２のサーモサイフォン回路２００を構成する。 The second pipe 60 has a second liquid passage 61 and a second gas passage 62. The second liquid passage 61 includes an outlet port 521 provided in the lower header tank 52 of the second connection heat exchanger 50, an outlet port 71 provided on the lower side of the air radiator 70, and a lower portion of the refrigerant radiator 80. It connects with the outflow inlet 81 provided on the side. The second gas passage 62 is disposed on the outlet / inlet 511 provided in the upper header tank 51 of the second connection heat exchanger 50, the outlet / inlet 72 provided above the air radiator 70, and above the refrigerant radiator 80. It is connected with the provided inlet / outlet port 82. That is, the second piping 60 complicates the various parts of the vehicle body between under the seat or trunk room of the vehicle provided with the battery pack 5 and in the engine room where the air radiator 70 and the refrigerant radiator 80 are provided. It will be circumvented. Thus, the second connection heat exchanger 50, the radiators 70, 80, the second liquid passage 61, and the second gas passage 62 constitute a second thermosiphon circuit 200 in which the second heat medium circulates.
　上述した第１実施形態の電池温調装置１は、車両製造時において、車両に対し電池パック５と第１のサーモサイフォン回路１００を設置する作業と、車両に対し第２のサーモサイフォン回路２００を設置する作業を、それぞれ別工程で行うことが可能である。そして、第１接続熱交換器３０の第１熱接触面３５と第２接続熱交換器５０の第２熱接触面５５とを直接接触または熱伝導部材４１を介して間接的に熱接触させることで、１つの熱回路としての電池温調装置１を構成することが可能である。 The battery temperature control device 1 according to the first embodiment described above includes the operation of installing the battery pack 5 and the first thermosiphon circuit 100 in the vehicle at the time of manufacturing the vehicle, and the second thermosiphon circuit 200 in the vehicle. It is possible to carry out the installation work in separate steps. Then, the first thermal contact surface 35 of the first connection heat exchanger 30 and the second thermal contact surface 55 of the second connection heat exchanger 50 are in direct thermal contact or indirect thermal contact via the thermal conductive member 41. Thus, it is possible to configure the battery temperature control device 1 as one thermal circuit.
　また、第１実施形態の電池温調装置１は、電池２のメンテナンス時において、第１接続熱交換器３０と第２接続熱交換器５０とを分離すれば、電池パック５と共に第１のサーモサイフォン回路１００を車両から容易に取り外すことが可能である。そして、第１のサーモサイフォン回路１００と第２のサーモサイフォン回路２００に対する第１、第２熱媒体の抜き取り作業および再充填作業を行うことなく、電池２のメンテナンスを短時間で容易に行うことが可能である。 In addition, if the battery temperature adjustment device 1 of the first embodiment separates the first connection heat exchanger 30 and the second connection heat exchanger 50 at the time of maintenance of the battery 2, the first thermo The siphon circuit 100 can be easily removed from the vehicle. Then, maintenance of the battery 2 can be easily performed in a short time without performing the work of extracting and refilling the first and second heat mediums with respect to the first thermosiphon circuit 100 and the second thermosiphon circuit 200. It is possible.
　図３は、電池温調装置１が電池２を冷却するときの第１のサーモサイフォン回路１００の第１熱媒体と、第２のサーモサイフォン回路２００の第２熱媒体の動きを示している。図３では、気体の第１、第２熱媒体の動きを破線の矢印で示し、液体の第１、第２熱媒体の動きを実線の矢印で示している。 FIG. 3 shows the movement of the first heat medium of the first thermosyphon circuit 100 and the second heat medium of the second thermosyphon circuit 200 when the battery temperature control device 1 cools the battery 2. In FIG. 3, the movement of the first and second heat transfer media of the gas is indicated by broken arrows, and the movement of the first and second heat transfer media of the liquid is indicated by solid arrows.
　電池２が発熱すると、その熱は電池用熱交換器１０内の第１熱媒体に吸熱され、電池用熱交換器１０で第１熱媒体が蒸発する。電池用熱交換器１０で気体となった第１熱媒体は、電池用熱交換器１０から第１気体通路２２を通り、第１接続熱交換器３０に流入する。すなわち、電池用熱交換器１０から第１接続熱交換器３０へ第１熱媒体によって熱が輸送される。 When the battery 2 generates heat, the heat is absorbed by the first heat medium in the battery heat exchanger 10, and the first heat medium evaporates in the battery heat exchanger 10. The first heat medium that has become gas in the battery heat exchanger 10 flows from the battery heat exchanger 10 through the first gas passage 22 into the first connection heat exchanger 30. That is, heat is transported from the battery heat exchanger 10 to the first connection heat exchanger 30 by the first heat medium.
　上述したように、第１接続熱交換器３０が有する第１熱接触面３５と第２接続熱交換器５０が有する第２熱接触面５５とは、直接接触または熱伝導部材４１を介して間接的に熱接触している。そのため、第１接続熱交換器３０と第２接続熱交換器５０では、第１熱媒体と第２熱媒体との熱交換が行われる。すなわち、第１接続熱交換器３０と第２接続熱交換器５０との間を熱接触によって熱が輸送される。第１熱媒体の温度より第２熱媒体の温度が低い場合、第１接続熱交換器３０内で第１熱媒体は第１、第２熱接触面３５、５５を介して第２熱媒体に放熱して凝縮する。第１接続熱交換器３０で液体となった第１熱媒体は、第１液体通路２１を通り、電池用熱交換器１０に流入する。 As described above, the first thermal contact surface 35 of the first connection heat exchanger 30 and the second thermal contact surface 55 of the second connection heat exchanger 50 are in direct contact or indirectly through the thermal conduction member 41. In thermal contact. Therefore, in the first connection heat exchanger 30 and the second connection heat exchanger 50, heat exchange between the first heat medium and the second heat medium is performed. That is, heat is transported by thermal contact between the first connection heat exchanger 30 and the second connection heat exchanger 50. When the temperature of the second heat medium is lower than the temperature of the first heat medium, the first heat medium is transferred to the second heat medium via the first and second heat contact surfaces 35 and 55 in the first connection heat exchanger 30. Heat dissipates and condenses. The first heat medium that has become liquid in the first connection heat exchanger 30 flows into the battery heat exchanger 10 through the first liquid passage 21.
　一方、その場合、第２接続熱交換器５０内で第２熱媒体は第１、第２熱接触面３５、５５を介して第１熱媒体から吸熱して蒸発する。第２接続熱交換器５０で気体となった第２熱媒体は、第２接続熱交換器５０から第２気体通路６２を通り、放熱器７０、８０に流入する。放熱器７０、８０内で第２熱媒体は、外気、冷凍サイクルの冷媒、または冷却水など、外部の熱媒体に放熱して凝縮する。すなわち、第２接続熱交換器５０から放熱器７０、８０へ第２熱媒体によって熱が輸送され、外部の熱媒体に放熱される。放熱器７０、８０で液体となった第２熱媒体は、第２液体通路６１を流下し、第２接続熱交換器５０に流入する。 On the other hand, in that case, in the second connection heat exchanger 50, the second heat medium absorbs heat from the first heat medium via the first and second thermal contact surfaces 35, 55 and evaporates. The second heat medium that has become a gas in the second connection heat exchanger 50 flows from the second connection heat exchanger 50 through the second gas passage 62 into the radiators 70 and 80. In the radiators 70 and 80, the second heat medium dissipates heat to the external heat medium such as the outside air, the refrigerant of the refrigeration cycle, or the cooling water and condenses. That is, heat is transported from the second connection heat exchanger 50 to the radiators 70 and 80 by the second heat medium, and is dissipated to the external heat medium. The second heat medium that has become liquid in the radiators 70 and 80 flows down the second liquid passage 61 and flows into the second connection heat exchanger 50.
　このようにして、電池２から生じた熱は、電池用熱交換器１０、第１接続熱交換器３０、第２接続熱交換器５０、放熱器７０、８０の順に輸送された後、外部の熱媒体に放熱される。これにより、第１実施形態の電池温調装置１は、車両に搭載される電池２を冷却することが可能である。 Thus, the heat generated from the battery 2 is transported from the battery heat exchanger 10, the first connection heat exchanger 30, the second connection heat exchanger 50, and the radiators 70, 80 in this order, and then the external heat Heat is dissipated to the heat medium. Thereby, the battery temperature control device 1 of the first embodiment can cool the battery 2 mounted on the vehicle.
　以上説明した第１実施形態の電池温調装置１は、次の作用効果を奏するものである。
　（１）第１実施形態の電池温調装置１は、第１のサーモサイフォン回路１００を構成する電池用熱交換器１０、第１配管２０および第１接続熱交換器３０と、第２のサーモサイフォン回路２００を構成する熱源部４０とを備えている。第１接続熱交換器３０と、熱源部４０が備える第２接続熱交換器５０とは、着脱可能に構成されている。そして、第１接続熱交換器３０が有する第１熱接触面３５と、第２接続熱交換器５０が有する第２熱接触面５５とは、重力方向に沿うように形成され、直接接触または熱伝導部材４１を介して間接的に熱接触する構成である。 The battery temperature control device 1 according to the first embodiment described above has the following effects.
(1) The battery temperature control device 1 according to the first embodiment includes the battery heat exchanger 10, the first pipe 20, and the first connection heat exchanger 30, which constitute the first thermosiphon circuit 100, and the second thermo And a heat source unit 40 constituting the siphon circuit 200. The 1st connection heat exchanger 30 and the 2nd connection heat exchanger 50 with which the heat source part 40 is provided are comprised so that attachment or detachment is possible. And the 1st thermal contact surface 35 which the 1st connection heat exchanger 30 has, and the 2nd thermal contact surface 55 which the 2nd connection heat exchanger 50 has are formed along the direction of gravity, and are directly contacted or heat The thermal contact is made indirectly via the conductive member 41.
　これによれば、車両製造時において、電池２に電池用熱交換器１０、第１配管２０および第１接続熱交換器３０を設置する作業と、車体に熱源部４０を設置する作業とを別工程で行うことが可能である。そして、第１接続熱交換器３０の第１熱接触面３５と、熱源部４０を構成する第２接続熱交換器５０の第２熱接触面５５とを直接接触または熱伝導部材４１を介して間接的に熱接触させることで、１つの熱回路としての電池温調装置１を構成することができる。 According to this, at the time of manufacturing the vehicle, the operation of installing the battery heat exchanger 10, the first pipe 20 and the first connection heat exchanger 30 in the battery 2 and the operation of installing the heat source section 40 in the vehicle body are different. It is possible to carry out in the process. Then, the first thermal contact surface 35 of the first connection heat exchanger 30 and the second thermal contact surface 55 of the second connection heat exchanger 50 constituting the heat source unit 40 are in direct contact or via the thermal conduction member 41. By indirect thermal contact, the battery temperature control device 1 as one thermal circuit can be configured.
　また、電池２のメンテナンス時において、車体に熱源部４０の第２配管６０が複雑に取り回されている場合でも、第１接続熱交換器３０と第２接続熱交換器５０を分離すれば、電池２と第１のサーモサイフォン回路１００を一緒に車両から取り外すことが可能である。そのため、第１のサーモサイフォン回路１００および第２のサーモサイフォン回路２００に対する第１、第２熱媒体の抜き取り作業および再充填作業を行うことなく、電池２のメンテナンスを短時間で容易に行うことが可能である。したがって、この電池温調装置１は、車両製造時における電池温調装置１の組付け性と、車両使用時における電池２のメンテナンス性を高めることができる。 In addition, even when the second piping 60 of the heat source unit 40 is intricately wound around the vehicle body at the time of maintenance of the battery 2, if the first connection heat exchanger 30 and the second connection heat exchanger 50 are separated, It is possible to remove the battery 2 and the first thermosiphon circuit 100 together from the vehicle. Therefore, the battery 2 can be easily maintained in a short time without performing the work of extracting and refilling the first and second heat mediums with respect to the first thermosiphon circuit 100 and the second thermosiphon circuit 200. It is possible. Therefore, the battery temperature control device 1 can enhance the assemblability of the battery temperature control device 1 at the time of manufacturing the vehicle and the maintainability of the battery 2 at the time of use of the vehicle.
　（２）第１実施形態では、第１のサーモサイフォン回路１００を流れる第１熱媒体の液面ＦＬ１、ＦＬ２は、電池用熱交換器１０の内側の流路の途中に位置し、且つ、第１接続熱交換器３０の内側の流路の途中に位置している。これによれば、電池２の冷却時に、熱源部４０から第１接続熱交換器３０に冷熱が供給されると、電池用熱交換器１０で蒸発した第１熱媒体は、第１気体通路２２から第１接続熱交換器３０に流れる。そして、第１接続熱交換器３０で凝縮した第１熱媒体は、第１液体通路２１から電池用熱交換器１０に流れる。したがって、この電池温調装置１は、第１熱媒体を循環させ、電池２を冷却することが可能である。なお、電池温調装置１は、熱源部４０から第１接続熱交換器３０に温熱を供給する構成とすれば、第１接続熱交換器３０の内側で蒸発した第１熱媒体は、第１気体通路２２から電池用熱交換器１０に流れる。そして、電池用熱交換器１０で凝縮した第１熱媒体は、第１液体通路２１から第１接続熱交換器３０に流れる。したがって、この電池温調装置１は、第１熱媒体を循環させ、電池２を暖機することが可能である。なお、電池２を暖機する構成については、後述する第９および第１０実施形態で説明する。 (2) In the first embodiment, the liquid surfaces FL1 and FL2 of the first heat medium flowing through the first thermosiphon circuit 100 are located in the middle of the flow path inside the battery heat exchanger 10, and It is located in the middle of the flow path inside the 1-connected heat exchanger 30. According to this, when cold heat is supplied from the heat source unit 40 to the first connection heat exchanger 30 during cooling of the battery 2, the first heat medium evaporated in the battery heat exchanger 10 is the first gas passage 22. Flow to the first connection heat exchanger 30. Then, the first heat medium condensed in the first connection heat exchanger 30 flows from the first liquid passage 21 to the battery heat exchanger 10. Therefore, the battery temperature control device 1 can cool the battery 2 by circulating the first heat medium. If the battery temperature adjustment device 1 is configured to supply heat from the heat source unit 40 to the first connection heat exchanger 30, the first heat medium evaporated inside the first connection heat exchanger 30 is the first heat medium. It flows from the gas passage 22 to the battery heat exchanger 10. Then, the first heat medium condensed in the battery heat exchanger 10 flows from the first liquid passage 21 to the first connection heat exchanger 30. Therefore, the battery temperature control device 1 can warm the battery 2 by circulating the first heat medium. The configuration for warming up the battery 2 will be described in the ninth and tenth embodiments described later.
　（第２実施形態）
　第２実施形態について図４および図５を参照して説明する。第２実施形態は、第１実施形態に対して第１接続熱交換器３０の構成を変更したものであり、その他については第１実施形態と同様であるため、第１実施形態と異なる部分についてのみ説明する。なお、図４では、第１接続熱交換器３０の上ヘッダタンク３１と下ヘッダタンク３２を省略している。 Second Embodiment
The second embodiment will be described with reference to FIGS. 4 and 5. The second embodiment is the same as the first embodiment except that the configuration of the first connection heat exchanger 30 is modified with respect to the first embodiment, and therefore, parts different from the first embodiment Only explain. In FIG. 4, the upper header tank 31 and the lower header tank 32 of the first connection heat exchanger 30 are omitted.
　第２実施形態の第１接続熱交換器３０は、チューブ３３とチューブ３３との間に、伝熱部３６を備えている。また、第１接続熱交換器３０は、チューブ３３の内側の流路に、インナーフィン３４を備えている。インナーフィン３４は、重力方向に延びている。伝熱部３６も、重力方向に延びている。伝熱部３６は、例えばアルミニウムなど、熱伝導性の良好な厚肉材料で形成された部材である。なお、伝熱部３６は、厚肉材料で形成することに代えて、ヒートパイプで構成してもよい。 The first connection heat exchanger 30 of the second embodiment includes a heat transfer portion 36 between the tube 33 and the tube 33. In addition, the first connection heat exchanger 30 includes an inner fin 34 in the flow passage inside the tube 33. The inner fins 34 extend in the direction of gravity. The heat transfer portion 36 also extends in the gravity direction. The heat transfer portion 36 is a member formed of a thick material having good thermal conductivity, such as aluminum. The heat transfer portion 36 may be formed of a heat pipe instead of being formed of a thick material.
　伝熱部３６は、第１接続熱交換器３０のチューブ３３の内側の流路を流れる第１熱媒体の液面ＦＬ２を跨ぐように、チューブ３３に沿って重力方向に延びている。伝熱部３６は、第１接続熱交換器３０のチューブ３３の内側を流れる液相の第１熱媒体と、気相の第１熱媒体との熱伝導を行う機能を有している。すなわち、伝熱部３６を介して、第１接続熱交換器３０の内側の液相の第１熱媒体と、気相の第１熱媒体の熱移動が効率よく行われる。そのため、熱源部４０から第１接続熱交換器３０への熱の伝達効率が良くなる。 The heat transfer portion 36 extends in the gravity direction along the tube 33 so as to straddle the liquid surface FL2 of the first heat medium flowing in the flow passage inside the tube 33 of the first connection heat exchanger 30. The heat transfer section 36 has a function of performing heat conduction between the liquid phase first heat medium flowing inside the tube 33 of the first connection heat exchanger 30 and the gas phase first heat medium. That is, the heat transfer between the liquid phase first heat medium and the gas phase first heat medium inside the first connection heat exchanger 30 is efficiently performed via the heat transfer section 36. Therefore, the heat transfer efficiency from the heat source unit 40 to the first connection heat exchanger 30 is improved.
　また、伝熱部３６は、第１接続熱交換器３０のうち、第１熱接触面３５に対して第２熱接触面５５とは反対側に設けられている。これにより、伝熱部３６は、第１熱接触面３５と第２熱接触面５５との間の熱移動を妨げることなく、第１接続熱交換器３０のチューブ３３の内側を流れる液相の第１熱媒体と、気相の第１熱媒体との熱伝導を行うことが可能である。したがって、第２実施形態の電池温調装置１は、伝熱部３６を備えることにより、電池２の冷却能力および暖機能力を高めることができる。 Further, the heat transfer portion 36 is provided on the opposite side of the first thermal contact surface 35 to the second thermal contact surface 55 in the first connection heat exchanger 30. Thus, the heat transfer portion 36 does not impede the heat transfer between the first thermal contact surface 35 and the second thermal contact surface 55, and the liquid phase of the liquid phase flowing inside the tube 33 of the first connection heat exchanger 30. It is possible to conduct heat conduction between the first heat carrier and the gas phase first heat carrier. Therefore, the battery temperature control device 1 of the second embodiment can enhance the cooling capacity and the warming function of the battery 2 by including the heat transfer portion 36.
　なお、上述した伝熱部３６は、第１接続熱交換器３０に設けることに限らず、第２接続熱交換器５０に設けてもよい。このことは、後述する第３および第４実施形態でも同じである。 In addition, the heat transfer part 36 mentioned above may be provided not only in the 1st connection heat exchanger 30 but in the 2nd connection heat exchanger 50. This is the same in the third and fourth embodiments described later.
　（第３実施形態）
　第３実施形態について図６および図７を参照して説明する。第３実施形態は、第２実施形態に対して第１接続熱交換器３０の構成を変更したものであり、その他については第２実施形態と同様であるため、第２実施形態と異なる部分についてのみ説明する。なお、図６でも、第１接続熱交換器３０の上ヘッダタンク３１と下ヘッダタンク３２を省略している。 Third Embodiment
A third embodiment will be described with reference to FIGS. 6 and 7. The third embodiment is the same as the second embodiment except that the configuration of the first connection heat exchanger 30 is modified with respect to the second embodiment, and therefore parts different from the second embodiment Only explain. Also in FIG. 6, the upper header tank 31 and the lower header tank 32 of the first connection heat exchanger 30 are omitted.
　第３実施形態では、第１接続熱交換器３０のチューブ３３を形成する部材自体が伝熱部３６を構成している。チューブ３３と伝熱部３６は共に、例えばアルミニウムなど、熱伝導性の良好な厚肉材料で形成された部材である。伝熱部３６を介して、第１接続熱交換器３０の内側の液相の第１熱媒体と、気相の第１熱媒体の熱移動が効率よく行われる。そのため、熱源部４０から第１接続熱交換器３０への熱の伝達効率が良くなる。 In the third embodiment, the member itself forming the tube 33 of the first connection heat exchanger 30 constitutes the heat transfer portion 36. The tube 33 and the heat transfer section 36 are both members made of a thick material having good thermal conductivity, such as aluminum. The heat transfer of the liquid phase first heat medium and the gas phase first heat medium inside the first connection heat exchanger 30 is efficiently performed via the heat transfer section 36. Therefore, the heat transfer efficiency from the heat source unit 40 to the first connection heat exchanger 30 is improved.
　また、伝熱部３６は、第１熱接触面３５を形成する部位の厚みＴ１より、第１熱接触面３５から第２熱接触面５５とは反対側に延びる部位の厚みＴ２の方が肉厚となるように形成されている。これにより、伝熱部３６は、第１熱接触面３５と第２熱接触面５５との間の熱移動を妨げることなく、第１接続熱交換器３０のチューブ３３の内側を流れる液相の第１熱媒体と、気相の第１熱媒体との熱伝導を行うことが可能である。したがって、第３実施形態の電池温調装置１は、伝熱部３６を備えることにより、電池２の冷却能力および暖機能力を高めることができる。 Further, in the heat transfer portion 36, the thickness T2 of the portion extending from the first thermal contact surface 35 to the opposite side to the second thermal contact surface 55 is thinner than the thickness T1 of the portion forming the first thermal contact surface 35.

Thus, the heat transfer portion 36 does not impede the heat transfer between the first thermal contact surface 35 and the second thermal contact surface 55, and the liquid phase of the liquid phase flowing inside the tube 33 of the first connection heat exchanger 30. It is possible to conduct heat conduction between the first heat carrier and the gas phase first heat carrier.

　第４実施形態でも、第１接続熱交換器３０のチューブ３３を形成する部材自体が伝熱部３６を構成している。伝熱部３６は、例えばアルミニウムなど、熱伝導性の良好な厚肉材料で形成された部材である。伝熱部３６は、第１接続熱交換器３０のうち、第１熱接触面３５を形成する部位と、その部位に対してチューブ３３の内側の流路を挟んで第１熱接触面３５とは反対側の部位に設けられている。伝熱部３６を介して、第１接続熱交換器３０の内側の液相の第１熱媒体と、気相の第１熱媒体の熱移動が効率よく行われる。そのため、熱源部４０から第１接続熱交換器３０への熱の伝達効率が良くなる。したがって、第４実施形態の電池温調装置１も、伝熱部３６を備えることにより、電池２の冷却能力および暖機能力を高めることができる。 Also in the fourth embodiment, the member itself forming the tube 33 of the first connection heat exchanger 30 constitutes the heat transfer portion 36. The heat transfer portion 36 is a member formed of a thick material having good thermal conductivity, such as aluminum. The heat transfer portion 36 includes a portion of the first connection heat exchanger 30 which forms the first thermal contact surface 35, and the first thermal contact surface 35 with the flow passage inside the tube 33 with respect to the portion. Is provided at the opposite site. The heat transfer of the liquid phase first heat medium and the gas phase first heat medium inside the first connection heat exchanger 30 is efficiently performed via the heat transfer section 36.

It may be a heat medium.
　第２接続熱交換器５０は、第２熱接触面５５を有している。第２熱接触面５５も、重力方向に沿うように形成されている。第１接続熱交換器３０と第２接続熱交換器５０とは、上述した第１実施形態と同様に、着脱可能に構成されている。すなわち、車両に電池温調装置１を設置する際、または、車両に設置された電池２のメンテナンスを行う際に、第１接続熱交換器３０と第２接続熱交換器５０とは、容易に着脱可能な構成である。 The second connection heat exchanger 50 has a second thermal contact surface 55.

In that case, the refrigerant flowing through the refrigeration cycle 85 is an example of an external heat medium. Further, instead of the refrigerant radiator 80, the radiator may be configured by a liquid cooling radiator that exchanges heat with a liquid such as cooling water flowing in a liquid circuit (not shown). In that case, a liquid such as cooling water is also an example of the external heat medium.
　第２配管６０は、第２往路６３および第２復路６４を有している。第２往路６３は、第２接続熱交換器５０の下方に設けられた流出入口５２１と、空気放熱器７０の下側に設けられた流出入口７１と、冷媒放熱器８０の下側に設けられた流出入口８１とを接続している。第２復路６４は、第２接続熱交換器５０の上方に設けられた流出入口５１１と、空気放熱器７０の上側に設けられた流出入口７２と、冷媒放熱器８０の上側に設けられた流出入口８２とを接続している。したがって、第２配管６０は、電池パック５が設けられた車両の座席下またはトランクルーム下と、空気放熱器７０および冷媒放熱器８０が設けられるエンジンルーム内との間で、車体の各部を複雑に取り回されることになる。第２往路６３または第２復路６４には、第２ポンプ６５が設けられている。第２ポンプ６５が駆動すると、第２の液回路４００に第２熱媒体が循環する。 The second pipe 60 has a second outward path 63 and a second return path 64.

It will be circumvented. A second pump 65 is provided in the second outward path 63 or the second return path 64. When the second pump 65 is driven, the second heat medium circulates in the second fluid circuit 400.
　上述した第５実施形態の電池温調装置１は、第１実施形態と同様に、車両製造時において、車両に対し電池パック５と第１の液回路３００を設置する作業と、車両に対し第２の液回路４００を設置する作業を、それぞれ別工程で行うことが可能である。そして、第１接続熱交換器３０の第１熱接触面３５と第２接続熱交換器５０の第２熱接触面５５とを直接接触または熱伝導部材４１を介して間接的に熱接触させることで、１つの熱回路としての電池温調装置１を構成することが可能である。 Similar to the first embodiment, the battery temperature adjustment device 1 according to the fifth embodiment described above installs the battery pack 5 and the first liquid circuit 300 in the vehicle when the vehicle is manufactured, and It is possible to perform the work of installing the two liquid circuits 400 in separate steps. Then, the first thermal contact surface 35 of the first connection heat exchanger 30 and the second thermal contact surface 55 of the second connection heat exchanger 50 are in direct thermal contact or indirect thermal contact via the thermal conductive member 41. Thus, it is possible to configure the battery temperature control device 1 as one thermal circuit.
　また、第５実施形態の電池温調装置１は、第１実施形態と同様に、電池２のメンテナンス時において、第１接続熱交換器３０と第２接続熱交換器５０とを分離すれば、電池パック５と第１の液回路３００を一緒に車両から取り外すことが可能である。そのため、第１の液回路３００と第２の液回路４００に対する第１、第２熱媒体の抜き取り作業および再充填作業を行うことなく、電池２のメンテナンスを短時間で容易に行うことが可能である。 Further, as in the first embodiment, the battery temperature adjustment device 1 of the fifth embodiment separates the first connection heat exchanger 30 and the second connection heat exchanger 50 at the time of maintenance of the battery 2, It is possible to remove the battery pack 5 and the first fluid circuit 300 together from the vehicle. Therefore, the battery 2 can be easily maintained in a short time without performing the first and second heat medium extraction and refilling operations for the first and second liquid circuits 300 and 400. is there.
　図１０では、電池温調装置１が電池２を冷却するときの第１の液回路３００の第１熱媒体の動きと、第２の液回路４００の第２熱媒体の動きを実線の矢印で示している。電池温調装置１が電池２を冷却するとき、第１ポンプ２５と第２ポンプ６５とが駆動される。これにより、第１の液回路３００を第１熱媒体が循環し、第２の液回路４００を第２熱媒体が循環する。 In FIG. 10, the movement of the first heat medium of the first liquid circuit 300 and the movement of the second heat medium of the second liquid circuit 400 when the battery temperature control device 1 cools the battery 2 are indicated by solid arrows. It shows. When the battery temperature control device 1 cools the battery 2, the first pump 25 and the second pump 65 are driven. As a result, the first heat medium circulates in the first liquid circuit 300, and the second heat medium circulates in the second liquid circuit 400.
　電池２が発熱した熱は、電池用熱交換器１０内の第１熱媒体に吸熱される。電池用熱交換器１０で加熱された第１熱媒体は、第１復路２４を通り、第１接続熱交換器３０に流入する。第１接続熱交換器３０と第２接続熱交換器５０では、第１熱媒体と第２熱媒体との熱交換が行われる。すなわち、第１接続熱交換器３０と第２接続熱交換器５０との間を熱接触によって熱が輸送される。第１熱媒体の温度より第２熱媒体の温度が低い場合、第１接続熱交換器３０内で第１熱媒体は第１、第２熱接触面３５、５５を介して第２熱媒体に放熱する。第１接続熱交換器３０で冷却された第１熱媒体は、第１往路２３と第１ポンプ２５を通って電池用熱交換器１０に流入する。 The heat generated by the battery 2 is absorbed by the first heat medium in the battery heat exchanger 10. The first heat medium heated by the battery heat exchanger 10 flows into the first connection heat exchanger 30 through the first return path 24. In the first connection heat exchanger 30 and the second connection heat exchanger 50, heat exchange between the first heat medium and the second heat medium is performed. That is, heat is transported by thermal contact between the first connection heat exchanger 30 and the second connection heat exchanger 50. When the temperature of the second heat medium is lower than the temperature of the first heat medium, the first heat medium is transferred to the second heat medium via the first and second heat contact surfaces 35 and 55 in the first connection heat exchanger 30. Heat is released. The first heat medium cooled by the first connection heat exchanger 30 flows into the battery heat exchanger 10 through the first forward path 23 and the first pump 25.
　一方、第２接続熱交換器５０内で第２熱媒体は第１、第２熱接触面３５、５５を介して第１熱媒体から吸熱する。第２接続熱交換器５０で加熱された第２熱媒体は、第２復路６４を通り、放熱器７０、８０に流入する。放熱器７０、８０内で第２熱媒体は、外気または冷媒など、外部の熱媒体に放熱する。放熱器７０、８０で冷却された第２熱媒体は、第２往路６３と第２ポンプ６５を通って第２接続熱交換器５０に流入する。 On the other hand, in the second connection heat exchanger 50, the second heat medium absorbs heat from the first heat medium via the first and second thermal contact surfaces 35, 55. The second heat medium heated by the second connection heat exchanger 50 passes through the second return path 64 and flows into the radiators 70, 80. In the radiators 70 and 80, the second heat medium dissipates heat to an external heat medium such as ambient air or a refrigerant. The second heat medium cooled by the radiators 70 and 80 flows into the second connection heat exchanger 50 through the second outward path 63 and the second pump 65.
　このようにして、電池２から生じた熱は、電池用熱交換器１０、第１接続熱交換器３０、第２接続熱交換器５０、放熱器７０、８０の順に輸送された後、外部の熱媒体に放熱される。これにより、第５実施形態の電池温調装置１も、車両に搭載される電池２を冷却することが可能である。以上説明した第５実施形態の電池温調装置１は、第１実施形態等と同様の作用効果を奏することができる。 Thus, the heat generated from the battery 2 is transported from the battery heat exchanger 10, the first connection heat exchanger 30, the second connection heat exchanger 50, and the radiators 70, 80 in this order, and then the external heat Heat is dissipated to the heat medium. Thus, the battery temperature control device 1 of the fifth embodiment can also cool the battery 2 mounted on the vehicle. The battery temperature adjusting device 1 of the fifth embodiment described above can exhibit the same effects as those of the first embodiment and the like.
　（第６実施形態）
　第６実施形態について図１１を参照して説明する。第６実施形態は、第５実施形態に対して、第１接続熱交換器３０と第２接続熱交換器５０の間に、ペルチェ素子９０を備えたものである。すなわち、第６実施形態では、第１の液回路３００を流れる第１熱媒体と、第２の液回路４００を流れる第２熱媒体とは、ペルチェ素子９０を介して熱移動が行われる。 Sixth Embodiment
A sixth embodiment will be described with reference to FIG. In the sixth embodiment, a Peltier element 90 is provided between the first connection heat exchanger 30 and the second connection heat exchanger 50 in the fifth embodiment. That is, in the sixth embodiment, heat transfer is performed between the first heat medium flowing in the first liquid circuit 300 and the second heat medium flowing in the second liquid circuit 400 via the Peltier element 90.
　電池２の冷却時、ペルチェ素子９０は、ペルチェ素子９０のうち第１熱接触面３５側の面９１が冷却面となり、ペルチェ素子９０のうち第２熱接触面５５側の面９２が放熱面となる。これにより、熱源部４０から第１接続熱交換器３０に冷熱を供給する場合、熱源部４０の第２熱接触面５５の温度を、ペルチェ素子９０でより低い温度にして、第１熱接触面３５に供給することが可能である。具体的には、第２熱接触面５５の温度≧ペルチェ素子９０のうち第２熱接触面５５側の面９２の温度＞ペルチェ素子９０のうち第１熱接触面３５側の面９１の温度となる。そのため、例えば熱源部４０が外気温に応じた冷熱を第２接続熱交換器５０から第１接続熱交換器３０に供給する構成である場合、ペルチェ素子９０を介することにより、第１接続熱交換器３０に対し、外気温よりも低い所望の温度の冷熱を供給することができる。以上説明した第６実施形態の電池温調装置１も、第１実施形態等と同様の作用効果を奏することができる。 At the time of cooling of the battery 2, in the Peltier device 90, the surface 91 on the first thermal contact surface 35 side of the Peltier device 90 is a cooling surface, and the surface 92 on the second thermal contact surface 55 of the Peltier element 90 is a heat dissipation surface Become. Thereby, when supplying heat from the heat source unit 40 to the first connection heat exchanger 30, the temperature of the second thermal contact surface 55 of the heat source unit 40 is made lower by the Peltier element 90, and the first thermal contact surface It is possible to supply 35. Specifically, the temperature of the second thermal contact surface 55 温度 the temperature of the surface 92 on the second thermal contact surface 55 of the Peltier element 90> the temperature of the surface 91 on the first thermal contact surface 35 of the Peltier element 90 Become. Therefore, for example, when the heat source unit 40 is configured to supply cold heat corresponding to the outside air temperature from the second connection heat exchanger 50 to the first connection heat exchanger 30, the first connection heat exchange is performed via the Peltier element 90. Cold heat of a desired temperature lower than the outside air temperature can be supplied to the vessel 30. The battery temperature control apparatus 1 of the sixth embodiment described above can also achieve the same function and effect as those of the first embodiment and the like.
　（第７実施形態）
　第７実施形態について図１２を参照して説明する。第７実施形態は、第１実施形態に対して、第１接続熱交換器３０と第２接続熱交換器５０の間に、ペルチェ素子９０を備えたものである。すなわち、第７実施形態では、第１のサーモサイフォン回路１００を流れる第１熱媒体と、第２のサーモサイフォン回路２００を流れる第２熱媒体とは、ペルチェ素子９０を介して熱移動が行われる。ペルチェ素子９０の機能については、第６実施形態で説明したことと同様である。したがって、第７実施形態の電池温調装置１も、第１実施形態等と同様の作用効果を奏することができる。 Seventh Embodiment
A seventh embodiment will be described with reference to FIG. According to the seventh embodiment, a Peltier element 90 is provided between the first connection heat exchanger 30 and the second connection heat exchanger 50 in the first embodiment. That is, in the seventh embodiment, heat transfer is performed via the Peltier element 90 between the first heat medium flowing through the first thermosiphon circuit 100 and the second heat medium flowing through the second thermosiphon circuit 200. . The function of the Peltier device 90 is the same as that described in the sixth embodiment. Therefore, the battery temperature control apparatus 1 of the seventh embodiment can also achieve the same function and effect as those of the first embodiment and the like.
　（第８実施形態）
　第８実施形態について図１３を参照して説明する。第８実施形態は、第６および第７実施形態の組み合わせである。第８実施形態でも、第１接続熱交換器３０と第２接続熱交換器５０の間に、ペルチェ素子９０を備えている。すなわち、第７実施形態では、第１のサーモサイフォン回路１００を流れる第１熱媒体と、第２の液回路４００を流れる第２熱媒体とは、ペルチェ素子９０を介して熱移動が行われる。第８実施形態の電池温調装置１も、第１実施形態等と同様の作用効果を奏することができる。 Eighth Embodiment
The eighth embodiment will be described with reference to FIG. The eighth embodiment is a combination of the sixth and seventh embodiments. Also in the eighth embodiment, the Peltier element 90 is provided between the first connection heat exchanger 30 and the second connection heat exchanger 50. That is, in the seventh embodiment, heat transfer is performed between the first heat medium flowing in the first thermosiphon circuit 100 and the second heat medium flowing in the second liquid circuit 400 via the Peltier element 90.

The heating unit 45 is a device capable of heating the second heat medium flowing through the second thermosiphon circuit 200. Although not shown, the second connection heat exchanger 50 is separately connected to the second pipe 60 provided with the heating unit 45 and the second pipe 60 provided with the radiators 70 and 80.

When the battery temperature adjusting device 1 warms up the battery 2, the heating unit 45 is driven. Further, the flow path is switched by the flow path switching valve 46, and the second heat medium circulates between the heating unit 45 and the second connection heat exchanger 50 without passing through the radiators 70 and 80.
　加熱部４５が第２熱媒体を加熱すると、蒸発して気体となった第２熱媒体は、加熱部４５から第２接続熱交換器５０に流入する。すなわち、加熱部４５から第２接続熱交換器５０へ第２熱媒体によって熱が輸送される。第２接続熱交換器５０と第１接続熱交換器３０では、第２熱接触面５５と第１熱接触面３５を介して、第２熱媒体と第１熱媒体との熱交換が行われる。第２熱媒体の温度より第１熱媒体の温度が低い場合、第２接続熱交換器５０内で第２熱媒体は第１、第２熱接触面３５、５５を介して第１熱媒体に放熱して凝縮する。第２接続熱交換器５０で液体となった第２熱媒体は、再び加熱部４５に流入する。 When the heating unit 45 heats the second heat medium, the second heat medium that has evaporated into a gas flows from the heating unit 45 into the second connection heat exchanger 50. That is, heat is transported from the heating unit 45 to the second connection heat exchanger 50 by the second heat medium. In the second connection heat exchanger 50 and the first connection heat exchanger 30, heat exchange between the second heat medium and the first heat medium is performed via the second heat contact surface 55 and the first heat contact surface 35. . When the temperature of the first heat medium is lower than the temperature of the second heat medium, the second heat medium is transferred to the first heat medium via the first and second heat contact surfaces 35 and 55 in the second connection heat exchanger 50. Heat dissipates and condenses. The second heat medium that has become liquid in the second connection heat exchanger 50 flows into the heating unit 45 again.
　一方、第１接続熱交換器３０内で第１熱媒体は第１、第２熱接触面３５、５５を介して第２熱媒体から吸熱して蒸発する。第１接続熱交換器３０で気体となった第１熱媒体は、第１接続熱交換器３０から第１気体通路２２を通り、電池用熱交換器１０に流入する。電池用熱交換器１０で第１熱媒体は、電池２に放熱して凝縮する。すなわち、電池用熱交換器１０から電池２へ第１熱媒体によって熱が輸送され、電池２が暖機される。電池用熱交換器１０で液体となった第１熱媒体は、第１液体通路２１から再び第１接続熱交換器３０に流入する。このようにして、加熱部４５から生じた熱は、第２接続熱交換器５０、第１接続熱交換器３０、電池用熱交換器１０、電池２の順に輸送される。 On the other hand, in the first connection heat exchanger 30, the first heat medium absorbs heat from the second heat medium via the first and second thermal contact surfaces 35, 55 and evaporates. The first heat medium that has become a gas in the first connection heat exchanger 30 flows from the first connection heat exchanger 30 through the first gas passage 22 into the battery heat exchanger 10. In the battery heat exchanger 10, the first heat medium releases heat to the battery 2 and condenses. That is, heat is transported from the battery heat exchanger 10 to the battery 2 by the first heat medium, and the battery 2 is warmed up. The first heat medium that has become liquid in the battery heat exchanger 10 flows into the first connection heat exchanger 30 again from the first liquid passage 21. Thus, the heat generated from the heating unit 45 is transported in the order of the second connection heat exchanger 50, the first connection heat exchanger 30, the battery heat exchanger 10, and the battery 2.
　第９実施形態の電池温調装置１は、熱源部４０が備える第２接続熱交換器５０から第１接続熱交換器３０に温熱を供給することで、第１のサーモサイフォン回路１００に第１熱媒体を循環させ、電池２を暖機することが可能である。 The battery temperature adjustment device 1 according to the ninth embodiment supplies the first heat to the first connection heat exchanger 30 from the second connection heat exchanger 50 provided in the heat source unit 40, thereby providing the first thermosiphon circuit 100 with the first temperature. The heat medium can be circulated to warm up the battery 2.
　なお、図示していないが、第１熱接触面３５と第２熱接触面５５との間にペルチェ素子９０を配置してもよい。これにより、熱源部４０が備える第２接続熱交換器５０から第１接続熱交換器３０に温熱を供給する場合、熱源部４０の第２熱接触面５５の温度をペルチェ素子９０でより高い温度として、第１熱接触面３５に供給することができる。 Although not shown, the Peltier element 90 may be disposed between the first thermal contact surface 35 and the second thermal contact surface 55. Thereby, when supplying heat from the second connection heat exchanger 50 included in the heat source unit 40 to the first connection heat exchanger 30, the temperature of the second thermal contact surface 55 of the heat source unit 40 is higher by the Peltier element 90 Can be supplied to the first thermal contact surface 35.
　（第１０実施形態）
　第１０実施形態について図１５を参照して説明する。第１０実施形態は、第８実施形態に対し、第２のサーモサイフォン回路２００に加熱部４５と流路切替弁４６を設けたものである。図１５では、電池温調装置１が電池２を暖機するときの第１のサーモサイフォン回路１００の第１熱媒体の動きを実線と破線の矢印で示し、第２の液回路４００の第２熱媒体の動きを実線の矢印で示している。電池温調装置１が電池２を暖機するとき、加熱部４５とポンプ６５が駆動される。また、流路切替弁４６により流路が切り替えられ、第２熱媒体は、加熱部４５と第２接続熱交換器５０との間を、放熱器７０、８０を介することなく循環する。 Tenth Embodiment

Further, the flow path is switched by the flow path switching valve 46, and the second heat medium circulates between the heating unit 45 and the second connection heat exchanger 50 without passing through the radiators 70 and 80.
　加熱部４５により加熱された第２熱媒体は、加熱部４５から第２接続熱交換器５０に流入する。第２熱媒体の温度より第１熱媒体の温度が低い場合、第２接続熱交換器５０内で第２熱媒体は第１、第２熱接触面３５、５５を介して第１熱媒体に放熱する。第２接続熱交換器５０で放熱して冷えた第２熱媒体は、再び加熱部４５に流入する。第１のサーモサイフォン回路１００の第１熱媒体の動きは、第９実施形態で説明した第１熱媒体の動きと同じである。第１０実施形態の電池温調装置１も、第９実施形態と同様の作用効果を奏することができる。 The second heat medium heated by the heating unit 45 flows from the heating unit 45 into the second connection heat exchanger 50.

The heat source unit is configured to be attachable to and detachable from the connection heat exchanger, and has a second thermal contact surface that is in direct thermal contact with the first thermal contact surface or in indirect thermal contact via a thermal conduction member. And a heat source part can cool or heat the heat carrier which flows through a connection heat exchanger in the state where the 1st thermal contact side and the 2nd thermal contact side were in thermal contact.
　第２の観点によれば、配管は、液体通路と気体通路とを有する。液体通路は、電池用熱交換器のうちで熱媒体の液面より下側に設けられた流出入口と、接続熱交換器のうちで熱媒体の液面より下側に設けられた流出入口とを接続する。気体通路は、電池用熱交換器のうちで熱媒体の液面より上側に設けられた流出入口と、接続熱交換器のうちで熱媒体の液面より上側に設けられた流出入口とを接続する。電池用熱交換器と配管と接続熱交換器は、熱媒体が循環するサーモサイフォン回路を構成している。サーモサイフォン回路を流れる熱媒体の液面は、電池用熱交換器の内側の流路の途中に位置し、且つ、接続熱交換器の内側の流路の途中に位置している。 According to a second aspect, the pipe has a liquid passage and a gas passage. The liquid passage includes an outlet / inlet provided below the liquid surface of the heat medium in the battery heat exchanger, and an outlet / inlet provided below the liquid surface of the heat medium in the connected heat exchanger. Connect The gas passage connects an outlet / inlet provided above the liquid surface of the heat medium in the battery heat exchanger and an outlet / inlet provided above the liquid surface of the heat medium in the connected heat exchanger. Do. The battery heat exchanger, the piping, and the connection heat exchanger constitute a thermosyphon circuit in which a heat medium circulates. The liquid surface of the heat medium flowing through the thermosyphon circuit is located midway in the flow path inside the battery heat exchanger, and midway in the flow path inside the connected heat exchanger.

Further, in the battery temperature control apparatus, the liquid surface of the heat medium is located midway in the flow path inside the battery heat exchanger and located midway in the flow path inside the connection heat exchanger It is possible to both cool and warm up the battery.

Thereby, the battery temperature control device can cool the battery. On the other hand, when heat is supplied from the heat source unit to the connection heat exchanger, the heat medium evaporated in the connection heat exchanger flows from the gas passage to the battery heat exchanger. The heat medium condensed by the battery heat exchanger flows from the liquid passage to the connection heat exchanger. Thereby, the battery temperature control apparatus can warm up the battery.

According to this, heat is transmitted via the heat transfer portion between the heat medium of the liquid phase inside the connection heat exchanger and the heat medium of the gas phase.

　第５の観点によれば、伝熱部は、第１熱接触面を形成する部位の厚みより、第１熱接触面から第２熱接触面とは反対側に延びる部位の厚みの方が肉厚となるように形成されている。これによれば、伝熱部は、第１熱接触面と第２熱接触面との間の熱移動を妨げることなく、接続熱交換器の内側を流れる液相の熱媒体と気相の熱媒体との熱伝導を行うことが可能である。 According to the fifth aspect, in the heat transfer portion, the thickness of the portion extending from the first thermal contact surface to the opposite side to the second thermal contact surface is thinner than the thickness of the portion forming the first thermal contact surface It is formed to be thick.
