（産業上の利用分野）
本考案は瞬間湯沸器等吸熱フインを介して吸熱
管内の通水を加熱するような熱交換器に関するも
のである。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a heat exchanger such as an instantaneous water heater that heats water passing through an endothermic tube through an endothermic fin.

５の経路で吸熱される。(Prior Art) Conventionally, this type of heat exchanger, as shown in FIG.
The structure includes a plurality of heat absorbing pipes 5 to which heat absorbing fins 3 are fixed and communicating with water pipes 4. FIG. 2 shows a partially enlarged sectional view of a conventional example, in which the side end portions of the heat absorbing fins 3 are fixed to the side plate 2a of the heating cylinder 2 by brazing. The reason why such fixation is performed in the conventional example is to alleviate the temperature rise of the side plate 2a of the heating cylinder 2, and heat is absorbed through the path of the side plate 2a→the heat absorbing fin 3→the heat absorbing tube 5.

破壊される問題が発生した。(Problem to be solved by the invention) However, in such a conventional example, a large temperature gradient occurs between the fixed part A of the heat absorbing fin 3 and the non-fixed part B of the side plate 2a, and the heat absorbing fin 3 expands due to long-term use. A problem occurred in that the boundary C between the two parts was destroyed by the force.

めたものである。(Means for Solving the Problems) In order to solve the above problems, the present invention has a plurality of heat absorption tubes to which a large number of heat absorption fins are fixed, and the heat absorption tubes are supported by a heating cylinder. Between the end of the heat absorption fin side and the side plate of the heating cylinder, a shielding plate whose lower part extends below the heat absorption fin along the side plate of the heating cylinder and shields the side plate below the heat absorption fin from the inside is connected to the side plate of the heat absorption fin and the heating cylinder. It is sandwiched in a non-adhesive state.
（実施例）
以下図示の一実施例に基づいて本考案の構成を
具体的に説明する。尚従来例と同一の構成のもの
は同一番号を付してその説明を省略する。(Example) The configuration of the present invention will be specifically described below based on an example shown in the drawings. Components having the same configuration as those of the conventional example are given the same reference numerals and their explanations will be omitted.
６は遮熱板であり、遮熱板６は吸熱フイン３側
端部と側板２ａ間に挾んで取着され、遮熱板６は
吸熱フイン３並びに側板２ａとは固着しておら

フイン３下方に延設して延設部分６ａにより吸熱
フイン３下方の側板２ａを内方より遮蔽してい
る。尚遮熱板６は上端部を内方へ折曲して、この
折曲部６ｂを吸熱フイン３上端の切欠き部７上に
係止せしめてある。８は側板２ａ上端に取付けて
燃焼ガスを中央部に導びくための整流板である。 6 is a heat shield plate, and the heat shield plate 6 is attached between the end of the heat absorbing fin 3 and the side plate 2a, and the heat shield plate 6 is not fixed to the heat absorbing fin 3 or the side plate 2a; The tube 5 is supported by a side plate 2a on a plane perpendicular to the axis. The lower part of the heat shield plate 6 extends below the heat absorbing fin 3 along the side plate of the heating cylinder, and the extended portion 6a shields the side plate 2a below the heat absorbing fin 3 from the inside. The upper end of the heat shield plate 6 is bent inward, and the bent portion 6b is locked onto the notch 7 at the upper end of the heat absorbing fin 3. Reference numeral 8 denotes a rectifier plate attached to the upper end of the side plate 2a to guide combustion gas to the center.
以上の構成において、熱交換器の加熱を行なう
と吸熱フイン３が熱膨張するが、吸熱フイン３の
この膨張力は遮熱板６で受止められ、この遮熱板
６で力が分散されてしまい、側板２ａに力が集中
することはないのである。加えて遮熱板６は吸熱
フイン３下方に延設して側板２ａを内方より遮蔽
してあるのでバーナからの吸熱フイン３下方の側
板２ａへの直接の熱供給がなく、側板２ａの遮熱
板６に接する部分と吸熱フイン３下方の部分との
温度勾配も小さくなる。 In the above configuration, when the heat exchanger is heated, the heat absorption fins 3 thermally expand, but this expansion force of the heat absorption fins 3 is received by the heat shield plate 6, and the force is dispersed by the heat shield plate 6. Therefore, the force is not concentrated on the side plate 2a. In addition, the heat shield plate 6 extends below the heat absorbing fins 3 and shields the side plate 2a from the inside, so there is no direct heat supply from the burner to the side plate 2a below the heat absorbing fin 3, and the side plate 2a is shielded. The temperature gradient between the portion in contact with the heat plate 6 and the portion below the heat absorbing fin 3 is also reduced.
（考案の効果）
以上に説明したように本考案によれば側板破壊
の要因である大きな温度勾配並びに側板への応力
集中を共に軽減することが出来、よつて熱交換器
の耐久性の向上に大きく寄与することが出来るの
である。(Effects of the invention) As explained above, according to the invention, it is possible to reduce both the large temperature gradient and stress concentration on the side plates, which are the causes of side plate failure, and thus improve the durability of the heat exchanger. It can make a big contribution.
