【産業上の利用分野】[Industrial applications]

この考案は、多数の円形皿状プレートを積み重ねて各プレート間に偏平な流路 を構成した積層型熱交換器に関し、特にその偏平流路内に筒状連通部が形成され たものであって、その筒状連通部外周を流通する流体の抵抗を可及的に小とした ものに関する。 The present invention relates to a laminated heat exchanger in which a large number of circular dish-shaped plates are stacked to form a flat flow path between the plates, and in particular, a cylindrical communication part is formed in the flat flow path. , The resistance of the fluid flowing around the outer periphery of the tubular communication portion is made as small as possible.

【従来の技術】[Prior art]

従来、丸多板型オイルクーラと称される積層型熱交換器は、皿状に形成された 円形プレートに一対のオイル流出入孔と一対の冷却水連通孔とを交互に配置し、 オイルを一方の流出入孔から他方の孔に偏平流路内を孤状に流通させるものであ る。この一対のオイル出入口間には、冷却水の連通部が筒状に立ち上げられ、オ イル流路の障害物の一部を構成する。この冷却水連通部は、外周が円形でありそ の連通孔とプレートの外周縁及び中心部との間における偏平流路は、その横断面 が狭くならざるを得なかった。そのため、オイルの流通抵抗が大きくなり、その 分だけオイルの流通が阻害されると共に、熱交換器の内部圧が高くなる欠点があ った。 Conventionally, a laminated heat exchanger called a multi-plate type oil cooler has a dish-shaped circular plate in which a pair of oil inflow / outflow holes and a pair of cooling water communication holes are alternately arranged to transfer oil. It is an inflow in the flat flow path from one inflow / outflow hole to the other hole. Between the pair of oil inlets and outlets, a communication part of the cooling water is erected in a cylindrical shape and constitutes a part of the obstacle of the oil passage. The cooling water communication part has a circular outer periphery, and the flat flow path between the communication hole and the outer peripheral edge and the central part of the plate had to have a narrow cross section. Therefore, the flow resistance of the oil is increased, the flow of the oil is obstructed accordingly, and the internal pressure of the heat exchanger is increased.

【課題を解決するための手段】[Means for Solving the Problems]

そこで本考案は、流体の流通抵抗を可及的に小さくするものであり、その目的 達成のために次の構成をとる。 本考案の積層型熱交換器は、多数の円形皿状プレート1,2が積層され、夫々 の周縁が互いに接合されて、前記各プレート1,2間に偏平流路3が形成された 積層型熱交換器において、 前記流路内を一方から他方に流体が流通するように、夫々の前記プレート1, 2に周方向に離間して形成された一対の流体出入り口4,4と、 前記両出入り口4の中間に位置して隣接する前記プレート間の一部を連通し、 その断面外周が前記プレート1,2の中心にほぼ同心となる孤状の繭形に形成さ れて、前記偏平流路3内に立ち上げられた筒状連通部5と、 を具備することを特徴とするものである。 Therefore, the present invention aims to reduce the flow resistance of the fluid as much as possible, and adopts the following configuration in order to achieve the purpose. The laminated heat exchanger of the present invention is a laminated heat exchanger in which a large number of circular dish-shaped plates 1 and 2 are laminated and their peripheral edges are joined to each other to form a flat flow path 3 between the plates 1 and 2. In the heat exchanger, a pair of fluid inlets and outlets 4 and 4 formed in the plates 1 and 2 so as to be circumferentially separated so that a fluid flows from one side to the other side in the flow path, and the both inlets and outlets. 4. The flat flow path is formed by connecting a part of the adjacent plates located in the middle of 4 and forming a cocoon shape having an outer periphery in cross section which is substantially concentric with the centers of the plates 1 and 2. And a cylindrical communicating portion 5 which is erected in the inside of the container 3.

【作用】[Action]

本考案の積層型熱交換器は、一方の出入り口4から他方の出入り口4に孤状に 流体が流通するとき、その中間部に存在する筒状連通部5は外周が中心に対して ほぼ同心となる孤状の繭形に形成されているから、流体の流通断面積を大きくと りつつ、その外周の流通抵抗を小さくし、熱交換媒体の流通が円滑に行われる。 即ち、図1及び図2に示す如く流体の一例としてオイル7が筒状連通部5の外周 に円滑に導かれる。しかも、その筒状連通部5内の断面積を同一とすると、その 幅が小さい分だけ筒状連通部5周縁部の偏平流路断面積が大きくなり、連通部内 の流体の流通が円滑になる。 In the laminated heat exchanger of the present invention, when the fluid flows from one inlet / outlet port 4 to the other inlet / outlet port 4 in an arc shape, the cylindrical communication portion 5 existing in the middle portion thereof has an outer periphery substantially concentric with the center. Since it is formed in an arcuate cocoon shape, the flow passage area of the fluid is increased, the flow resistance of the outer circumference is reduced, and the heat exchange medium is smoothly flowed. That is, as shown in FIGS. 1 and 2, the oil 7 as an example of the fluid is smoothly guided to the outer periphery of the tubular communication portion 5. Moreover, if the cross-sectional area of the tubular communication portion 5 is the same, the flat flow passage cross-sectional area of the peripheral portion of the tubular communication portion 5 increases due to the smaller width, and the fluid flow in the communication portion becomes smooth. .

【考案の効果】[Effect of device]

本考案の積層型熱交換器は、多数の円形皿状のプレート1,2が積層され各プ レート1,2間に偏平流路3が形成されたものにおいて、その偏平流路3内に障 害物として存在する筒状連通部5の断面外周がプレートの中心にほぼ同心となる 孤状の繭形に形成されているから、偏平流路3内を流通する流体の流通抵抗を可 及的に少なくし得る。即ち、筒状連通部5が流れの方向に沿って孤状に形成され ているため、その流体抵抗が小さく熱交換媒体を円滑に流通させ、熱交換を促進 させる効果がある。そして、偏平流路3内の流体の内圧を低く抑え、耐久性の高 い積層型熱交換器を提供し得る。 In the laminated heat exchanger of the present invention, a large number of circular plate-shaped plates 1 and 2 are laminated and a flat flow path 3 is formed between the plates 1 and 2, and the flat flow path 3 has an obstacle. Since the cross-sectional outer periphery of the tubular communication portion 5 existing as a harmful substance is formed in an cocoon shape of an arc shape that is substantially concentric with the center of the plate, it is possible to reduce the flow resistance of the fluid flowing in the flat flow passage 3. Can be less. That is, since the tubular communication portion 5 is formed in an arc shape along the flow direction, the fluid resistance thereof is small, and the heat exchange medium can be smoothly circulated to promote heat exchange. Then, the internal pressure of the fluid in the flat flow path 3 can be suppressed to a low value, and a highly durable laminated heat exchanger can be provided.
