Things are used. In particular, in an electric vehicle, since the capacity of an assembled battery is required due to the need for extending the cruising distance, a plurality of assembled batteries are combined in series or in parallel.
ところで、二次電池は、使用温度によって性能や寿命が変化するので、長時間にわたって効率良く使用するためには適正な温度で使用する必要がある。しかしながら、上述した組電池においては、各単電池間に比較的大きな温度差が生じ、その結果単電池が劣化して寿命が短くなるという問題がある。 By the way, since the performance and life of the secondary battery change depending on the use temperature, it is necessary to use it at an appropriate temperature in order to use it efficiently for a long time. However, in the above-described assembled battery, there is a problem that a relatively large temperature difference occurs between the single cells, and as a result, the single cells are deteriorated to shorten the life.

A plurality of remaining passages formed side by side continuously on the other side of the coolant circulation body become the outflow side passage, the inlet header leads to the inflow side passage, and the outlet header leads to the outflow side passage. The intermediate header communicates with the inflow side passage and the outflow side passage, the inlet header, the outlet header and the intermediate header are brazed to the coolant flow body, the inlet pipe is brazed to the inlet header, and the outlet A liquid cooling type cooling device in which a pipe is brazed to an outlet header has been proposed (see Patent Document 1).
特許文献１記載の液冷式伝熱装置の場合、複数の単電池からなる１つの組電池が冷却液流通体の発熱体取付面に熱的に接触させられるようになっており、複数の組電池を同時に冷却する場合には、複数の液冷式伝熱装置が直列状または並列状に接続されて用いられる。 In the case of the liquid-cooled heat transfer device described in Patent Document 1, one assembled battery made up of a plurality of single cells is brought into thermal contact with the heating element mounting surface of the coolant circulation body. When simultaneously cooling the battery, a plurality of liquid-cooled heat transfer devices are connected in series or in parallel.

And the second flow pipe part and the two flow pipe parts are integrally connected to each other so that the flow direction of the heat transfer medium in both flow pipe parts is opposite to each other. And a heat transfer medium circulating body is connected to the heat transfer medium inlet pipe at the end opposite to the U-turn pipe in the first flow pipe, and the second flow pipe Since the heat transfer medium outlet pipe is communicated with the end portion on the opposite side of the U-turn pipe section, the object is in thermal contact with at least one side surface in the pipe height direction of both flow pipe sections. , Heat is transferred between the object and the heat transfer medium flowing in both flow pipes. . Therefore, by flowing a low-temperature heat transfer medium, it becomes possible to take heat from a plurality of high-temperature objects and simultaneously cool the objects. Conversely, by flowing a high-temperature heat transfer medium, a plurality of low-temperature objects can be cooled. It becomes possible to heat the object at the same time by applying heat.
しかも、各伝熱媒体流通体は、第１および第２流通管部と、両流通管部に一体に設けられ、かつ両流通管部内での伝熱媒体の流れ方向が逆向きとなるように両流通管部の端部どうしを一体に連結するＵターン管部とよりなるので、各伝熱媒体流通体を１つの扁平管を用いて作ることが可能となり、特許文献１記載の伝熱装置を複数用意する場合に比べて、部品点数を低減しうるとともに製造作業が容易になる。 Moreover, each heat transfer medium flow body is provided integrally with the first and second flow pipe sections and both flow pipe sections, and the flow direction of the heat transfer medium in both flow pipe sections is opposite. Since it consists of the U-turn pipe part which connects the end parts of both flow pipe parts integrally, it becomes possible to make each heat transfer medium flow body using one flat pipe, and the heat transfer device described in Patent Document 1 Compared to the case of preparing a plurality of components, the number of parts can be reduced and the manufacturing operation can be facilitated.
上記2)および3)の伝熱装置によれば、物体を各伝熱媒体流通体の両流通管部の上面および下面のうち少なくとも一方に熱的に接触させることにより、物体と流通管部内を流れる伝熱媒体との間で熱を授受することが可能になる。 According to the heat transfer device of 2) and 3) above, the object and the inside of the flow pipe part are brought into thermal contact with at least one of the upper and lower surfaces of both flow pipe parts of each heat transfer medium flow body. Heat can be exchanged with the flowing heat transfer medium.
上記3)の伝熱装置によれば、伝熱媒体入口管および伝熱媒体出口管のうちいずれか一方の管が他方の管よりも上方に配置されている場合であっても、各伝熱媒体流通体の両流通管部の上面および下面をそれぞれ同一水平面上に位置させることができる。したがって、物体を各伝熱媒体流通体の両流通管部の上面および下面のうち少なくとも一方に熱的に接触させる場合において、物体と流通管部内を流れる伝熱媒体との間での熱の授受効率が向上する。 According to the heat transfer device of the above 3), even if any one of the heat transfer medium inlet pipe and the heat transfer medium outlet pipe is disposed above the other pipe, The upper surface and the lower surface of both the flow pipe portions of the medium flow body can be positioned on the same horizontal plane. Therefore, when an object is brought into thermal contact with at least one of the upper and lower surfaces of both flow pipe portions of each heat transfer medium flow body, heat is transferred between the object and the heat transfer medium flowing in the flow pipe portion. Efficiency is improved.
上記4)および5)の伝熱装置によれば、物体を各伝熱媒体流通体の両流通管部の両側面に熱的に接触させることにより、多くの物体と流通管部内を流れる伝熱媒体との間で熱を授受することが可能になる。 According to the heat transfer device of the above 4) and 5), heat transfer that flows in a large number of objects and the flow pipe portions by bringing the objects into thermal contact with both side surfaces of both flow pipe portions of each heat transfer medium flow body. Heat can be exchanged with the medium.
上記5)の伝熱装置によれば、下向き連通管および上向き連通管を用いるだけですべての伝熱媒体流通体の第１および第２流通管部の管厚み方向の両側面を、それぞれ同一鉛直面上に位置させた状態で、両流通管部を伝熱媒体入口管および伝熱媒体出口管に接続することができる。 According to the heat transfer device of the above 5), both the side surfaces in the tube thickness direction of the first and second flow pipe portions of all the heat transfer medium flow bodies are the same vertical by using only the downward communication pipe and the upward communication pipe. Both flow pipe parts can be connected to the heat transfer medium inlet pipe and the heat transfer medium outlet pipe in a state of being positioned on the surface.
上記6)の伝熱装置によれば、略Ｕ形伝熱媒体流通体を比較的簡単な方法でつくることができる。たとえば、略Ｕ形伝熱媒体流通体の製造方法の一例が、特許第５１３３７７１号公報に記載されている。 According to the heat transfer device of the above 6), a substantially U-shaped heat transfer medium circulating body can be produced by a relatively simple method. For example, an example of a method for producing a substantially U-shaped heat transfer medium circulating body is described in Japanese Patent No. 5133771.
