FIELD: heating.SUBSTANCE: distribution chamber (6) is bounded outside by the housing and a bottom (3) and interconnects the central supply channel (9) and two lateral discharge channels (1) through the gaps between the bottom (3) and the end parts of the inner walls (2). The housing is formed by two outer walls (5). In each side discharge channel (1) parallel to the housing walls with a gap in relation to each other the system of plates (7) is mounted, forming the channels (4) for the passage of working medium. The central supply channel (9) is separated from the side discharge channels (1) by the inner walls (2) oriented along the walls of the housing. The outer (5) and inner (5) walls, the bottom (3) and the system of plates (7) are mounted vertically and made in the form of flat plates. The void ratio of the system of plates (7) corresponds to the range from 0.3 to 0.8. For the distribution chamber (6) the ratios are given, taking into account the relationships: firstly, the height of the distribution chamber (6) and the width of the central supply channel (9); secondly, the height of the inlet to the distribution chamber 6 and the width of the central supply channel; thirdly, the height of the distribution chamber (6), the height of the inlet to it and the width of the central supply channel (9); fourth, the half-width of the lower part of the housing, the width of the central supply channel (9), the height of the distribution chamber (6) and the height of the inlet to it and the width of the outer part of the central supply channel (9); fifthly, the distance from the bottom (3) to the step (8) on the housing, respectively, with the height of the inlet to the distribution chamber (6) and with the width of the central supply channel (9), the half-width of the lower part of the housing and the height of the inlet to the distribution chamber (6); sixthly, the half-width of the lower part of the housing, the width of the central supply channel (9) and the height of the inlet to the distribution chamber (6). The ratio on choosing the size of the flow part of the distribution chamber (6) is given, taking into account the average rates of the working medium in the channel (4) of the system of plates (7) and in the channels (4) of the system of plates (7), the half-width of the upper part of the housing, the width of the outer part of the central supply channel (9), the current half-width of the system of plates (7), three empirical coefficients and the width of the stream of the working medium falling on the system of plates.EFFECT: enhanced functionality of the device, while ensuring the given hydrodynamic inequality at the outlet of the distribution chamber and simplification of its structure.5 cl, 1 dwg |
