FIELD: heat exchange.
SUBSTANCE: invention relates to special nozzles, intended for action on fluid flow by forced separation of flow entering the nozzle into multiple internal flows of smaller nominal diameter to ensure its turbulent-laminar transition. Technical problem to be solved by the disclosed technical solution consists in the need to create a special nozzle in the form of a branch pipe, characterized by a simple and reliable design. Multitunnel nozzle of constant cross section for turbulent-laminar transition of water flow is a branch pipe, wherein inside this branch pipe four longitudinally oriented plates are installed, which in a rectangular coordinate system OX, OY, OZ are oriented by their planes parallel to the axis OZ, which is simultaneously the axis of this branch pipe, wherein these plates are connected to each other and divide the channel of the branch pipe into eight longitudinal tunnels, so that one plate of said four plates is located parallel to the coordinate plane ZOX, and other plates of said four plates are located parallel to coordinate plane YOZ, wherein these other plates are located at a distance from each other and from the inner walls of the branch pipe to form eight longitudinal tunnels of the multitunnel nozzle.
EFFECT: instead of multiple shaped pipes, only one branch pipe is used.
