PURPOSE: To make a recirculation pump unnecessary and to make making easy as well by providing a pool boiling part underneath a heat exchanger tube, in a captioned vaporizer which causes a working fluid to be flowed down along a narrow groove of a heat exchanger tube arranged vertically.
CONSTITUTION: A device is so constituted that a pool boiling parts A is formed by winding a porous plate 14 on the external circumferential part A of a heat exchanger tube 2 provided vertically, a working fluid to be supplied is flowed down in a liquid film from a supply opening 11 on the outside of the heat exchanger tube 2 having a narrow groove 12, the liquid film is heated by a warm water flowing inside the tube 2 and a part of the liquid film is vaporized. Then, the unvaporized liquid is reached to the porous plate 14 and a vapor bubble B is generated and vaporized through the pool boiling. With this, constitution of a plant is simplified.
