The width ratio of the middle triangular inlet width to the whole cavity is 0.08: 1 to 0.3: 1. In the scheme, liquid water is added into the evaporator from the bottom, and in the process, the water is in a liquid phase; when the liquid water reaches the middle position, just reaching the boiling point, a phase change occurs. High-temperature water vapor enters the upper end through the distribution structure of the middle end. The gas phase water continues to absorb heat and is finally discharged from the upper part. The scheme has the advantages that in the liquid phase stage, the heat is fully exchanged through the S-shaped flow channel; in the gas phase stage, heat exchange is carried out fully through the vertical flow channel. The structure has high heat exchange efficiency.
