    The invention relates to heat engineering and can be used in the application of heat exchanging media with a large pressure difference, in particular for cooling the fission gases with the aid of evaporating water.
    The purpose of the invention is to increase the operational reliability by preventing the particles contained in the water from settling on the tube plate.
    Figure 1 shows the proposed heat exchanger, a longitudinal section; figure 2 - section aa in figure 1.
    The heat exchanger contains a casing 1, a bundle of tubes 2 housed in it, fixed in tube plates 3 and 4, and a carrier plate 5 with holes 6 fixed to the casing 1, through which the tubes 2 of the bundle are passed through with a gap 7, the tube boards 3 and 4 have a different thickness and thinner pipe board 3 is installed with a gap of 8 with respect to the carrier plate 5, in which support elements are arranged, made in the form of fingers 9, located between the tubes 2 of the beam. An outer shell 10 with a water inlet I1 is installed around the casing in the area of the supporting plate 5, forming with the casing 1 an annular chamber 12 bounded by a thin tube plate 3 Casing 1 with diametrically opposite

    The side nozzle 11 is provided with an overflow hole 13. In the annular chamber 12, in a plane perpendicular to the axis of the water inlet nozzle 11, there are two longitudinal partitions 14 adjacent to the shell 10. In the finger placement area 9, the partitions 14 are provided with guide plates 15, In the upper part of the case is located the pipe 16 of the water outlet.
    Water containing impurities enters through the pipe P. In the pipe 2 serves a gaseous medium having a temperature greater than that of water. Water enters the annular chamber 12 and flows at high speed through the gap 8 between the pipe, the board 3 and the carrier plate 5, while a small amount of water flows through the annular gap 7 into the annular space. The main amount of water enters through the annulus 13 and, with its partial evaporation, cools the gas passing through the pipes 1. The evaporating water is discharged through the branch pipe 16 of the water drainage. The carrier plate 5, in addition to the function of supporting the thin tube board 3, serves to direct the water. In this case, the forces that go from the tube plate 3 through the carrying fingers 9 are directed in the form of tensile forces in
    the casing 1. Since the main amount of water enters the annular space through the opening 13, water is directed at a high speed across the entire tube plate 3, thereby preventing the trapped particles from settling on it.
