Purpose of work theoretical and experimental research intensification of heat exchange at turbulence current of heat-carriers with constant thermal by properties in direct round pipes with the inserted braided tape.

As a result of research the decisions for intensification of heat exchange were received at turbulence current of heat-carriers in the above-stated channels, more general, than existing. The decisions, received in the given research, support by an existing and original experimental material. The existing decisions are a special case of the new decisions. The received experimental data distinguish by originality. The realized theory allows more precisely to predict a level intensification of heat exchange, than available; the theory is necessary for using at operational development existing and development perspective heat exchangers of devices and devices.

The application of the developed settlement methods intensification of heat exchange will allow to lower metal-consuming and dimensions, and also temperature of walls perspective heat exchangers of devices with intensification by heat exchange.
