Swirling of second air flow is formed tangentially in direction of passing of first on-coming air flow. Device contains two plates. Pipeline is designed to transmit second air flow. One end of pipeline is made open and it is connected with surrounding space, and other end is connected to outer surface of one of plates. Converter is installed in pipeline. AT least one of plates is provided with space to swirl second air flow. Space communicates with pipeline. Space is made orthogonally relative to direction of first on-coming air flow tangentially in direction of first on-coming air flow.

EFFECT: improved efficiency of energy conversion.

Wind thermal plant // 2253041

FIELD: wind power engineering.

SUBSTANCE: invention relates to wind plants for direct conversion of wind energy into thermal energy. Proposed wind thermal plant contains windwheel with rotary blades and friction heat generator with heat exchanger. Novelty is that heat generator is made in form of conical drum with ribbed surface and rotor is provided with friction lining being installed on shaft of windwheel. Pressure of lining onto drum surface depends on wind head. Heat exchanger is provided with air intake. Windwheel is provided with speed and vibration protective device.

EFFECT: simplified design, improved reliability in operation within wide range of wind loads with provision of ventilation of heat rooms.
