To enhance the heat transmission performance of an evaporating tube and improve the dynamic behavior of an apparatus where an evaporator is used by a groove-shaped section extended in the longitudinal direction of an evaporating tube on the lower side of the evaporating tube.
Since the flow of a liquid of an evaporating tube 1 is the flow of an open channel, the free surface of the liquid is a surface having a slope falling obliquely from an inlet S1 to an outlet surface S3 by way of an intermediate surface S2. As a slit 12 is provided below a spring 11, the liquid can pass in the slit 12 below the souring so that there may be no need for the fluid to flow across the spring 11. As a result, the free surface may be formed in the range of a linear diameter of the spring 11. With the flow of the liquid as described above, any are a which many become not only a surface evaporation heating transfer surface but also a convection heat transfer surface having a low heat transfer rate, is the maximum in the inlet of the fluid and lead to A position from the bottom of the tube and may become substantially O in the outlet of the liquid.
