Description
図1は、本発明の実施の形態に係る捻り管式熱交換器を示す斜視図である。
捻り管式熱交換器100は、捻り管1を備えている。捻り管1の詳細は後述するが、該捻り管1は、後述のように、水等の第1流体が流れる第1配管10と、第1流体を加熱する冷媒が流れる第2配管20と、を備えている(後述の図2及び図3を参照)。また、本実施の形態に係る捻り管式熱交換器100は、捻り管1の一部に断熱材30が巻き付けられている。なお、本実施の形態に係る捻り管式熱交換器100は、長尺の(長さが長い)捻り管1を用いている。このため、本実施の形態に係る捻り管式熱交換器100は、捻り管1が複数段のとぐろ状(コイル状)に巻かれた形状となっている。とぐろ状部分の辺の長さ及び段数は、捻り管1の長さに応じて、適宜決定すればよい。
第1流体は、捻り管1を構成する第1配管10の入口側端部11から、該第1配管10の内部に流入する。この第1流体は、第1配管10の内部を、第2範囲42から第1範囲41に向かって流れる。そして、第1流体は、第1範囲41を流れている間に、第2配管20の内部を流れる冷媒によって加熱される。この加熱された第1流体は、第1配管10の出口側端部12から、捻り管式熱交換器100の外部に流出する。
Claims (5)
- 外周部に螺旋状の溝部が形成され、内部に第1流体が流れる第1配管と、
前記第1配管の前記溝部に一部が巻き付けられており、内部に前記第1流体を加熱する冷媒が流れる第2配管と、
を有する捻り管を備え、
前記第1配管と前記第2配管とが接合されている範囲を第1範囲と定義し、該第1範囲よりも前記第1配管の端部側に存在し、前記第1配管と前記第2配管とが接合されていない範囲を第2範囲と定義した場合、
前記第1範囲と前記第2範囲との境界部を含む一部の範囲に、該境界部における前記第1配管及び前記第2配管の外周部と、前記第2範囲における前記第1配管の外周部とを覆うように巻き付けられている断熱材を備えた捻り管式熱交換器。 - 前記断熱材は、ポリエチレン発泡樹脂で形成されている請求項1に記載の捻り管式熱交換器。
- 前記断熱材は、前記第2配管が挿入される穴と、該穴から当該断熱材の端部に至る切り込みとが形成されている請求項1又は請求項2に記載の捻り管式熱交換器。
- 前記捻り管は、複数段のとぐろ状に巻かれており、
前記一部の範囲と、該一部の範囲の上方に配置されている前記捻り管部分との間に、前記断熱材が配置されている請求項1〜請求項3のいずれか一項に記載の捻り管式熱交換器。 - 前記第1流体が前記第2範囲から前記第1範囲へ向かって流れる構成である請求項1〜請求項4のいずれか一項に記載の捻り管式熱交換器。
