Description

本発明は、筺体内で、管内を流れる湯水と筺体内に取り込んだ燃焼ガスとを熱交換する熱交換器及びその熱交換器を備える給湯装置に関する。 The present invention relates to a heat exchanger for heat exchange between hot water flowing in a pipe and combustion gas taken into the housing in the housing, and a hot water supply device including the heat exchanger.

筺体内に設けられた複数の管内を流れる湯水を、筺体内に取り込んだ燃焼ガスで加熱する熱交換器は、管が所定の間隔を空けて配置される。これは、管内の湯水と燃焼ガスとの熱交換の効率化を図るためである。また、管の間隔が狭くなった箇所には結露水がたまることから、管を所定の間隔を空けて配置することは、管の間に結露水がたまるのを防止する点でも有効である。
特許文献１には、曲げ加工が施された線材又は棒状部材を用いて、管を所定の間隔を空けて配置する例が記載されている。 In the heat exchanger that heats the hot water flowing in a plurality of pipes provided in the housing with the combustion gas taken into the housing, the pipes are arranged at predetermined intervals. This is to improve the efficiency of heat exchange between the hot water in the pipe and the combustion gas. Further, since dew condensation water collects in the place where the space between the pipes is narrowed, it is effective to arrange the pipes at a predetermined space in order to prevent the dew condensation water from accumulating between the pipes.
Patent Document 1 describes an example in which pipes are arranged at predetermined intervals by using a bent wire or rod-shaped member.

筺体１６の側壁部１５には、図２、図４（Ａ）、（Ｂ）、図５に示すように、それぞれ筺体１６の内側に突出した複数のエンボス（突起）２９が間隔を空けて設けられている。本実施の形態では、側壁部１５に複数のエンボス２９が鉛直方向に等ピッチで配されたエンボス２９の列が２つ存在する。
最上位置に配された管１７には、図２、図５に示すように、右側に配された上側の折り返し部２７に、下方から２つのエンボス２９が接触し、右側に配された下側の折り返し部に、上方及び下方からそれぞれ２つのエンボス２９が接触している。 As shown in FIGS. 2, 4 (A), (B), and 5, a plurality of embossed (projections) 29 protruding inward of the housing 16 are provided on the side wall portion 15 of the housing 16 at intervals. Has been done. In the present embodiment, there are two rows of embossed 29s in which a plurality of embossed 29s are arranged at equal pitches in the vertical direction on the side wall portion 15.
As shown in FIGS. 2 and 5, the tube 17 arranged at the uppermost position has two embossed 29s from below in contact with the upper folded portion 27 arranged on the right side, and the lower side arranged on the right side. Two embossed 29s are in contact with the folded portion of the above and below, respectively.

最下位置に配された管１７には、右側に配された上側の折り返し部２７に、上方及び下方からそれぞれ２つのエンボス２９が接触し、右側に配された下側の折り返し部に、上方から２つのエンボス２９が接触している。最上位置に配された管１７及び最下位置に配された管１７を除く管１７には、右側に配された２つの折り返し部２７それぞれに、上方及び下方からそれぞれ２つのエンボス２９が接触している。
従って、各管１７には、高さ位置が異なる複数のエンボス２９が接触していることとなる。 Two embossed 29s from above and below contact the upper folded portion 27 arranged on the right side of the pipe 17 arranged at the lowest position, and the lower folded portion arranged on the right side is upward. Two embossed 29s are in contact with each other. Two embossed 29s from above and below contact each of the two folded portions 27 arranged on the right side of the pipe 17 except for the pipe 17 arranged at the uppermost position and the pipe 17 arranged at the lowest position. ing.

It is positioned and brazed to the sidewall 14. Therefore, each pipe 17 is brazed to the side wall portion 14 in a state of being arranged at a predetermined position.

そして、側壁部１４にろう付けされた各管１７の右側は、右側に配置された折り返し部２７が複数のエンボス２９に接触することによって位置決めされている（即ち、各管１７はエンボス２９に接触して位置決めされている）ことから、潜熱熱交換器１０を輸送の際や、潜熱熱交換器１０を使用の際（例えば、ウォーターハンマーが生じた際）に管１７が所定位置からずれるのを安定的に抑制可能である。 The right side of each pipe 17 brazed to the side wall portion 14 is positioned by the folded portion 27 arranged on the right side coming into contact with a plurality of embossed 29s (that is, each pipe 17 comes into contact with the embossed portion 29). Therefore, when the latent heat exchanger 10 is transported or when the latent heat exchanger 10 is used (for example, when a water hammer occurs), the pipe 17 is prevented from being displaced from the predetermined position. It can be stably suppressed.

本実施の形態では、側壁部１５、即ち、第２の側壁部に、複数のエンボス２９が鉛直方向に等ピッチで配されたエンボス２９の列が２つ設けられているが、エンボス２８の配置はこれに限定されない。例えば、図６に示すように、側壁部５０（第２の側壁部の一例）に複数のエンボス５１が鉛直方向に等ピッチで配されたエンボス５１の列を１つ設け、このエンボス５１に各管１７の右側の折り返し部２７を接触させて、各管１７を位置決めするようにしてもよい。なお、図６において、図５に示す構成と同様の構成については同じ符号を付している。
