FIELD: machine building.SUBSTANCE: in mixing heat exchanger each nozzle of the system of supply of irrigating cold water consists of two coaxial cylindrical bushings. In the bushing with smaller diameter coaxially to it the worm is located the external surface of which is a screw groove, inside the worm the hole with screw threading is made, and in the bushing with bigger diameter coaxially to it the union is located which is rigidly fixed in it through the sealing gasket. In the union the cylindrical hole is made coaxially, which passes into axisymmetric diffuser which is connected with the cylindrical chamber formed by the internal surface of the bushing smaller minor diameter, and end surface of the worm; and to the end surface of the bushing with smaller diameter at least two inclined rods are secured; on each rod active sprayers are fixed, for example, in form of blades resting by bottom part on stops secured on rods at right angle to their axes, at that the rod are inclined from the sprayer axis i.e. along cone surface, the tip of which is directed towards the bushing with greater diameter.EFFECT: productivity increasing of the mixing heat-exchange in the device.2 dwg |
