PURPOSE:To perform cooling uniform in circumferential and axial directions by constituting a cooler of a ring pipe having plural pieces of injection ports formed by incising diagonally and notching the pipe toward the down flow direction of the inside swirling flow and plural pieces of injection pipes connected thereto from the direction tangential therewith and provided with orifices in the mid- way. CONSTITUTION:The cooler 11 is constituted by connecting, for example, two hot water ejecting pipes 12, 12a connected to the ring pipe 15 made of a steel pipe in the tangential direction thereof to hot water pipes via the evaporating orifices 13, 13a. Plural pieces of the injection ports 16 are provided to the pipe 15 by incising diagonally and notching said pipe in the down flow direction of the inside swirling flow. For example, the incising angle alpha of the injection port 16 is set at 45 deg. and 8 pieces of the ports 6 are provided equidistantly (beta=45 deg.) on the inside circumferential surface of the pipe 15. |
