［産業上の利用分野］
本願は、各種車両、油圧作動機に用いられるプ
レート型の熱交換器に関する。[Detailed Description of the Invention] [Industrial Application Field] The present application relates to a plate-type heat exchanger used in various vehicles and hydraulic actuators.
［従来の技術］
従来の熱交換器は、実公昭39−25540号公報に
しめされるように、対角線に上方に突出する上向
口と下方に突出する下向口とを有する盆形の層板
を多数積重し、溶着した構造のものである。な
お、このものの第一位の、つまり上段の層板に
は、４つの管を有する蓋板が、また最下位の層板
には、何等の開口を有しない底板が各々組み合わ
されて、積重式二回路の熱交換器を形成させてい
る。[Prior Art] As shown in Japanese Utility Model Publication No. 39-25540, a conventional heat exchanger has a tray-shaped layer having an upward opening projecting diagonally upward and a downward opening projecting downward. It has a structure in which many plates are stacked and welded together. In addition, the first layer, that is, the upper layer, has a lid plate with four tubes, and the lowest layer has a bottom plate with no openings. A two-circuit heat exchanger is formed.
蓋板の管の１つから流体が導入され、層板の奇
数板内を流通して、蓋板の管の対角線上にある管
へ流出する。また、他の流体は、層板の偶数板内
を流通して他の残りの管に向け流出する。 Fluid is introduced from one of the tubes in the lid plate, flows through the odd plates of the laminations, and exits into the tube diagonally opposite the tube in the lid plate. Further, other fluid flows through the even numbered plates of the laminar plates and flows out toward the other remaining tubes.
この間に、二種流体は相互に熱交換する。 During this time, the two fluids exchange heat with each other.
［考案が解決しようとする課題］
従来の熱交換器は、層板を単に積重させること
により、相互にシールされた二流体の流路をきわ
めて容易に形成できるという利点を有する反面、
耐圧構造が十分でなく、たとえば内燃機関の潤滑
油のように比較的高い流体圧が断続的長期にわた
り作用するような用途への利用を困難にする。す
なわち、底板とその上に位置している層板の下向
口端とは、当接構造になつており、また蓋板の管
の周囲が何等補給された構造となつていないため
である。[Problem to be solved by the invention] Conventional heat exchangers have the advantage that a mutually sealed flow path for two fluids can be formed very easily by simply stacking layered plates.
The pressure-resistant structure is insufficient, making it difficult to use in applications where relatively high fluid pressure is applied intermittently for long periods of time, such as lubricating oil for internal combustion engines. That is, the bottom plate and the downwardly facing end of the layered plate located thereon are in an abutting structure, and the area around the tube of the cover plate is not in any replenishing structure.
底板と上記下向口端とは、嵌合構造となつてい
ないので液密に接合するのが困難であるのに加え
て、一方流体の与える流体圧は全て下向口に断面
積分の底板で受けることになり、その結果、構造
強度が不十分となる。また蓋板下面の中央部は、
フインが挟着されているので、所定の構造強度が
得られるが、管の周囲はフインが無く、構造強度
が低下することになる。 The bottom plate and the above-mentioned downward opening end do not have a fitting structure, so it is difficult to join them liquid-tight. As a result, the structural strength becomes insufficient. In addition, the center part of the lower surface of the lid plate is
Since the fins are sandwiched together, a certain level of structural strength can be obtained, but since there are no fins around the tube, the structural strength is reduced.
そこで、これを改良するものとして次のような
熱交換器が提案されている。すなわち、第１図
１，ロに示すように両端部に一対の流体通孔１
a′，１b′を有する金属プレート１′が相互の間に

いる。金属プレート１′、接続フランジ２′、バー
B′、そして間隔板３′は、組立てに際して、第２
図のようにろー箔１０′を介して積層され、ろー
付により一体化される。 Therefore, the following heat exchanger has been proposed to improve this. That is, as shown in FIG.
bar B' on both sides so that the metal plate 1' having a', 1b' provides a fluid passage between each other;
In addition, a required number of fins are stacked at both ends with spacer plates 3' interposed between them, and corrugated fins 4' with a large number of window holes are provided in each fluid passage. Also, the even-numbered passages are used as passages for working fluid (oil or other fluids), for example, connecting flanges 2' to the vehicle body or equipment provided at both ends on the top metal plate 1'. Working fluid is taken in from the front passage hole 2a' on one side as shown by the solid line arrow and flows out from the rear passage hole 2b' on the other side, while the refrigerant is taken in from the front passage hole 2a' on the other side as shown by the dotted line arrow. This is taken out from the through hole 2b' at the rear of one side, and in the process heat exchange is performed between the fluids. The spacer plate 3' is provided with a through hole 3a' and a cutout hole 3b' opening toward the inside. Metal plate 1', connection flange 2', bar
B', and the spacing plate 3' is the second
As shown in the figure, they are laminated with a solder foil 10' interposed therebetween and integrated by brazing.
しかしながら、この提案されたものでは従来の
欠点は解消するが、各プレート間の流体通路形成
のために間隔板のほかに前後一対のバーを必要と
し、それだけ部品数が多くなると共に重量が重く
なり、しかも本体の組立てに当つてバーや間隔板
がずれ易く位置決めが巧くいかず、シールや不良
品ができ易い等の難点が残る。 However, although this proposed method eliminates the conventional drawbacks, it requires a pair of front and rear bars in addition to the spacer plate to form fluid passages between each plate, which increases the number of parts and increases the weight. Moreover, when assembling the main body, the bars and spacer plates tend to shift, making it difficult to position them properly, resulting in problems such as seals and defective products.
