Abstract: PURPOSE: An apparatus is provided to reduce the load of power supplying hot or cool water by minimizing inside pressure loss and by flowing in or discharging hot or cooling water with the same direction as a lengthy direction of a pipe and to improve a heat delivery rate by quickening a flow speed of hot or cooling water flowed in to an intake and discharged to an outlet. CONSTITUTION: Water and dewatering apparatuses comprise a body(210) of a circular shape, an intake(220) flowing in or discharging hot or cooling water through plural penetration holes placed on around edge portion except the penetration part position surrounding a thermosyphon(300) of both end portions perpendicular with the body(210), and an outlet(230). The thermosyphon(300) is inserted through the penetration part. The water and dewatering apparatuses have the intake(220) and the outlet(230) placed on the same direction as a lengthy direction of a pipe instead of a perpendicular direction of the previous apparatuses. The flowing in or discharging of hot or cooling water is not directly rushed to a perpendicular wall side or both end portions so that a swirl is not occurred and a pressure loss is minimized. Therefore, the load caught by a power source motor supplying hot or cooling water is reduced and a heat transfer rate is improved with the quickened flow speed of hot or cooling water.
