【発明の詳細な説明】
本発明は気体等の流体を流通させて熱交換を行
なう暖房用または給湯用に使用する熱交換器に関
するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat exchanger used for heating or hot water supply, which exchanges heat by circulating a fluid such as gas.
従来は、筒状の燃焼室の上部または側面部の開
口にバーナを嵌合させ、バーナより放出された燃
料を燃焼室で燃焼させ、排出口より放出するタイ
プの熱交換器においては、熱交換効率を向上する
ために、燃焼室内にバツフル等の抵抗体を装備し
たりしていた。 Conventionally, in heat exchangers, a burner is fitted into an opening at the top or side of a cylindrical combustion chamber, and the fuel released from the burner is combusted in the combustion chamber and discharged from the exhaust port. In order to improve efficiency, a resistor such as a buttful was installed inside the combustion chamber.
しかし上記構成では、熱交換器の中央部を流れ

り、流路に屈折部を設けたりすると流路抵抗が著
しく増え、流路抵抗が増えると燃焼室内圧も著し
く大きくなりバーナ、燃焼に大きな支障を与えて
いた。 However, in the above configuration, the combustion gas flowing through the center of the heat exchanger flows as it is without coming into contact with the heat exchanger wall. In other words, the degree of contact between the gas and the heat exchanger wall is poor, so the heat exchange efficiency cannot be sufficiently improved. Similarly, even in devices equipped with heat radiation fins, the combustion chamber wall and the heat exchanger inner wall are heated to a high temperature by the high-temperature gas. or the distance between the heat dissipation fins and the heated medium is long,
Since heat transfer was not carried out smoothly, the heat exchange effect was not very high. Also, in terms of machining, if welding between the combustion chamber and the heat exchanger becomes complicated, or if bends are provided in the flow path, the flow path resistance will increase significantly, and as the flow path resistance increases, the pressure in the combustion chamber will also increase significantly. The burner was causing a major hindrance to combustion.
本発明はこのような欠点を解消したもので、以
下その一実施例を説明する。 The present invention eliminates these drawbacks, and one embodiment thereof will be described below.

いる。 The outer shell 1 that forms the combustion chamber has a tapered shape that is wide on the burner 7 side, and has a circular (second round) shape that protrudes toward the combustion chamber 3 side.
(Fig.), has a large number of independent protrusions (protrusions) 2 with elliptical (Fig. 3) planes, and their arrangement can be at regular intervals (Fig. 4) or randomly (Fig. 5).
go to A discharge port 8 for combustion gas, which is a heat exchange medium, is provided at the top of the outer shell 1 in the opposite vicinity to the bottom of the outer shell 1.
外胴１底部と反対面は次に説明する内胴、およ
びバーナ７の押入を行うための開口となつてい
る。 The surface opposite to the bottom of the outer shell 1 is an opening into which an inner shell and a burner 7, which will be described next, are inserted.
無底筒状の内胴４は、外胴１同様バーナ７側が
広いテーパ状で外胴１に有した多数の突起部２の
平面に密着するような径にし、無底部片方を外胴
１内面に密着するように拡管した構成である。 Like the outer shell 1, the bottomless cylindrical inner shell 4 has a tapered shape with a wide side on the burner 7 side, and has a diameter such that it comes into close contact with the plane of the many protrusions 2 on the outer shell 1, and one side of the bottomless part is attached to the inner surface of the outer shell 1. The tube is expanded so that it comes into close contact with the tube.
外胴１の底部反対面開口より、内胴４を圧入す
る事で、内胴４の拡管部と外胴１が密着され、ま
た内胴４、外胴１間には突起部２により燃焼ガス
の流路６が形成される。 By press-fitting the inner shell 4 through the opening on the opposite side of the bottom of the outer shell 1, the expanded tube part of the inner shell 4 and the outer shell 1 are brought into close contact, and the protrusion 2 between the inner shell 4 and the outer shell 1 allows combustion gas to be A flow path 6 is formed.
上記組み合せで、バーナ７より放出された燃料

反対側の外胴１と内胴４のすきまより、流路６へ
流入し、外胴１上部の排気口８より器外へ放出さ
れる。 With the above combination, the fuel released from the burner 7 burns in the combustion chamber 3 and becomes combustion gas, which flows into the flow path 6 through the gap between the outer shell 1 and the inner shell 4 on the opposite side of the burner 7, and flows into the upper part of the outer shell 1. is discharged outside the device from the exhaust port 8.
燃焼室３内の燃焼ガスは、内胴４より熱を奪わ

列によりガスの流れを整流および乱流、スパイラ
ル状にして胴体との接触面積を増やす事もでき
る。 The combustion gas in the combustion chamber 3 loses heat from the inner shell 4. The heat is transmitted through the contact surfaces 10 of the projections 2 of the inner shell 4 and the outer shell 1, and is radiated to the heat exchange medium 9 (water) outside the vessel. Furthermore, when passing through the flow path 6, most of the combustion gas is forced into contact with the inner wall of the outer shell 1 and the protrusion 2, and heat is removed from the flow path contact surface and radiated to the heat exchange medium 9. Ru. Furthermore, the arrangement of the protrusions 2 allows the gas flow to be rectified, turbulent, or spiral, thereby increasing the contact area with the body.
また外胴１の突起部２を第６図のごとくスパイ
ラル状に形成すると突起部２と外胴１との接触面
積が増えることになり燃焼室３内の燃焼ガスのよ
り有効な活用が図れる。 Further, if the protrusion 2 of the outer shell 1 is formed in a spiral shape as shown in FIG. 6, the contact area between the protrusion 2 and the outer shell 1 increases, so that the combustion gas in the combustion chamber 3 can be used more effectively.
以上の説明から明らかなように本発明では次の
ような効果が得られる。 As is clear from the above description, the following effects can be obtained in the present invention.
内外胴により２重筒状にしたので内胴内の熱
交換媒体を内外胴間に通してその大部分を熱交
換に利用できるとともに内胴と外胴を突部で密
着させる事により、内胴内の高温ガスも有効に
活用が出来、トータルの熱交換効率は著しく向
上し省エネルギーにも結びつく。 Since it has a double cylindrical shape with the inner and outer shells, the heat exchange medium in the inner shell can be passed between the inner and outer shells and most of it can be used for heat exchange. The high-temperature gas inside can also be used effectively, significantly improving the total heat exchange efficiency and leading to energy savings.
また内胴と外胴をテーパ状にしているので両
者間に少々の寸法誤差があつても圧入する事に
より、突起部と外胴とを確実に密着させること
ができるとともに気密性を必要とする溶接等が
不要となり加工コストの低減に結びつく。 In addition, since the inner and outer shells are tapered, even if there is a slight dimensional error between the two, by press-fitting, the protrusion and the outer shell can be reliably brought into close contact, and airtightness is required. This eliminates the need for welding, etc., leading to a reduction in processing costs.
また外胴は被熱交換媒体と接していて比較的
低温に維持されるので例え多数の突部を設けて
いて複雑な熱収縮力が加わるような場合であつ
てもその熱変形は少なく長期間にわたつての使
用が可能となる。 In addition, since the outer shell is in contact with the heat exchange medium and is maintained at a relatively low temperature, even if it has many protrusions and is subjected to complex thermal contraction forces, its thermal deformation is small and long-term. It can be used for many years.
なお、外胴に独立した多数の突部、スパイラル
状の突部を設けたので被熱交換媒体との伝熱面積
が大きく取れ、小形でコンパクトな熱交換器が得
られる。 In addition, since a large number of independent protrusions and spiral protrusions are provided on the outer shell, a large heat transfer area with the heat exchange medium can be obtained, and a small and compact heat exchanger can be obtained.
