Description

【０００１】
【発明の属する技術分野】
本発明は、熱交換器のコア部構造に係わり、特に、対向配置される座板の両端部をレインフォースにより連結してなる熱交換器のコア部構造に関する。
【０００２】
【従来の技術】
従来、対向配置される座板の両端部をレインフォースにより連結してなるラジエータ等の熱交換器のコア部構造として、例えば、実開昭５６−１８５８９号公報に開示されるものが知られている。
【０００３】
図５は、この種の熱交換器のコア部構造を示すもので、この熱交換器のコア部では、所定間隔を置いて対向配置される座板１の間に、チューブ３とコルゲートフィン５とが交互に配置され、対向配置される座板１の両端部がレインフォース７により連結補強されている。
そして、チューブ３およびレインフォース７の両端部が、座板１に形成されるチューブ穴１ａおよびレインフォース穴１ｂに挿入されており、座板１，チューブ３，コルゲートフィン５およびレインフォース７が相互に熱処理炉内でろう付けされている。
【０００４】
このような熱交換器のコア部構造では、レインフォース７の端部７ａを、座板１のレインフォース穴１ｂに嵌挿して、ろう付けＲにより座板１に固定しているため、座板１の端部に配置されるチューブ３の付け根部を補強することができる。
【０００５】
【発明が解決しようとする課題】
しかしながら、従来の熱交換器のコア部構造では、図６に示すように、レインフォース７の端部７ａを、座板１のレインフォース穴１ｂに嵌挿して、ろう付けＲにより座板１に固定しているため、レインフォース７のろう付けＲされるレインフォース穴１ｂの近傍の座板１の剛性が高まり、レインフォース７に隣接して配置されるチューブ３の付け根部に亀裂が発生する虞があるという問題があった。
【０００６】
すなわち、例えば、ラジエータでは、冷水が流通しているチューブ３に急激に温水が流入する場合があり、このような場合には、チューブ３が急激に高温になり大きく熱膨張しようとするが、レインフォース７のろう付けＲされるレインフォース穴１ｂの近傍の座板１の剛性が高く、また、レインフォース７の温度が殆ど変化しないため、レインフォース７に隣接して配置されるチューブ３の付け根部に大きな熱応力が発生し、このチューブ３の付け根部に亀裂が発生する虞があるという問題があった。
【０００７】
なお、このような虞は、図６に示したように、チューブ３の幅Ｗが、例えば、３０mmより大きくなり、レインフォース７の幅が大きくなるに従って増大する。
また、ラジエータにおいて、冷水が流通しているチューブ３に急激に温水が流入する現象は、例えば、寒冷地でエンジンを始動した時に、エンジンの冷却水の水温が徐々に上昇するが、サーモスタットの開弁温度に達するまでは、ラジエータに冷却水が流れず、冷却水の温度が高温になり、サーモスタットの開弁により始めて温度の高い冷却水がラジエータに流入する場合、あるいは、寒冷地を走行中にサーモスタットが開閉を繰り返す、いわゆるハンチング現象の発生時等に生じる。
【０００８】
本発明は、かかる従来の問題を解決するためになされたもので、レインフォースに隣接して配置されるチューブの付け根部に作用する熱応力を従来より大幅に低減することができる熱交換器のコア部構造を提供することを目的とする。
【０００９】

【００１０】
請求項２の熱交換器のコア部構造は、所定間隔を置いて対向配置される座板の間に、チューブとフィンとを交互に配置するとともに、前記対向配置される座板の両端部にレインフォースを配置し、前記レインフォースの端部を前記座板に形成されるレインフォース穴に嵌挿固定してなる熱交換器のコア部構造において、前記レインフォースの端部の近傍に、レインフォースの端部の弾性変形を容易ならしめる肉抜き穴を形成してなることを特徴とする。
【００１１】

そして、レインフォース２７の端部２７ｃの近傍に、肉抜き穴２７ｄが形成されている。
この肉抜き穴２７ｄは、レインフォース２７の幅方向に長い矩形形状とされている。
この実施形態では、レインフォース２７の端部２７ｃの近傍に、肉抜き穴２７ｄを形成したので、この肉抜き穴２７ｄにより、レインフォース２７の端部２７ｃの弾性変形が比較的容易になり、この結果、レインフォース２７のろう付けＲされるレインフォース穴２１ｄの近傍の座板２１の剛性が極端に高まることがなくなり、レインフォース２７に隣接して配置されるチューブ２３の付け根部に作用する熱応力を従来より大幅に低減することができる。

【００２１】
また、上述した第２の実施形態では、レインフォース２７の端部２７ｃの近傍に矩形状の肉抜き穴２７ｄを形成した例について説明したが、本発明はかかる実施形態に限定されるものではなく、例えば、肉抜き穴の形状を楕円形状等の形状にしても良い。

BACKGROUND OF THE INVENTION
The present invention relates to a core part structure of a heat exchanger, and more particularly to a core part structure of a heat exchanger in which both end parts of seat plates arranged opposite to each other are connected by a reinforcement.
[0002]
[Prior art]
Conventionally, as a core part structure of a heat exchanger such as a radiator formed by connecting both ends of seat plates opposed to each other by a reinforcement, for example, what is disclosed in Japanese Utility Model Publication No. 56-18589 is known. Yes.
[0003]
FIG. 5 shows a core part structure of this type of heat exchanger. In the core part of this heat exchanger, a tube 3 and corrugated fins 5 are disposed between seat plates 1 arranged to face each other at a predetermined interval. Are alternately arranged, and both end portions of the opposed seat plates 1 are connected and reinforced by the reinforcement 7.
Both ends of the tube 3 and the reinforcement 7 are inserted into the tube hole 1a and the reinforcement hole 1b formed in the seat plate 1, and the seat plate 1, the tube 3, the corrugated fin 5 and the reinforcement 7 are mutually connected. Are brazed in a heat treatment furnace.
[0004]
In such a core structure of the heat exchanger, since the end 7a of the reinforcement 7 is fitted into the reinforcement hole 1b of the seat plate 1 and fixed to the seat plate 1 by brazing R, the seat plate The base part of the tube 3 arrange | positioned at the edge part of 1 can be reinforced.
[0005]
[Problems to be solved by the invention]
However, in the conventional heat exchanger core portion structure, as shown in FIG. 6, the end portion 7 a of the reinforcement 7 is inserted into the reinforcement hole 1 b of the seat plate 1 and brazed R to the seat plate 1. Since it is fixed, the rigidity of the seat plate 1 in the vicinity of the reinforcement hole 1b where the reinforcement of the reinforcement 7 is brazed is increased, and a crack occurs at the base of the tube 3 disposed adjacent to the reinforcement 7. There was a problem of fear.
[0006]
That is, for example, in a radiator, hot water may suddenly flow into the tube 3 through which cold water flows. In such a case, the tube 3 suddenly becomes high in temperature and tends to thermally expand. Since the rigidity of the seat plate 1 in the vicinity of the reinforce hole 1b to be brazed with the force 7 is high and the temperature of the reinforce 7 hardly changes, the root of the tube 3 disposed adjacent to the reinforce 7 is provided. There is a problem that a large thermal stress is generated in the portion, and there is a possibility that the base portion of the tube 3 is cracked.
[0007]
Such a fear increases as the width W of the tube 3 becomes larger than, for example, 30 mm and the width of the reinforcement 7 becomes larger as shown in FIG.
Also, in the radiator, the phenomenon that the warm water suddenly flows into the tube 3 through which the cold water flows is, for example, that when the engine is started in a cold region, the temperature of the engine cooling water gradually rises, but the thermostat is opened. Until the valve temperature is reached, the cooling water does not flow into the radiator, the temperature of the cooling water becomes high, and when the cooling water with a high temperature flows into the radiator for the first time by opening the thermostat, or while traveling in a cold region This occurs when the so-called hunting phenomenon occurs where the thermostat repeatedly opens and closes.
[0008]
The present invention has been made to solve such a conventional problem, and is a heat exchanger that can significantly reduce the thermal stress acting on the root of a tube disposed adjacent to the reinforcement. It aims at providing a core part structure.
[0009]
