FIELD: heating.SUBSTANCE: in mixing heat exchanger each nozzle of the irrigation cold water supply system contains the housing with the vortex chamber and the nozzle insert, while the housing is designed with the inlet branch pipe with the hole, the inlet cylindrical chamber, coaxial to it, the vortex chamber located coaxially with reference to the inlet chamber and implemented in the form of the cylindrical barrel which has on lateral surface, at least, three tangentially located holes the axes of which are located tangentially with reference to the turbulence chamber, i.e. this is the multichannel tangential input, and coaxially to the vortex chamber the nozzle insert with the external diameter Dis located, in the insert three calibrated holes are designed which are located in series and coaxially to each other and to cylindrical surface of the vortex chamber: the conic hole with the diameter D of the lower base of the truncated cone, the central cylindrical hole with the diameter dand outlet conic hole with the diameter dof the lower base of the truncated cone. The diameter dof the central cylindrical hole of the nozzle insert is equal to the diameter of the upper base of the truncated cone of the conic opening and the diameter of the upper base of the truncated cone of the outlet conic hole.EFFECT: increase of productivity of the mixing heat exchange in the device.3 dwg |
