Abstract
The invention discloses a wind power centralized heat management system, which relates to the technical field of heat management of wind driven generators, and is characterized in that each node in the system is provided with a pressure sensor and a temperature sensor which are used for detecting pressure and temperature values of a cooling medium of each node; manual stop valves are mounted at inlets and outlets of all parts, so that pipelines are conveniently blocked during system maintenance, and a cooling medium is prevented from leaking; for all the components needing to be cooled, the components with the similar required flow are connected in series according to the sequence of the flow from large to small; the three-way valve automatically adjusts the opening degree of the valve element according to the temperature value T3 or T7 fed back by the temperature sensor, and the flow Q1 and the flow Q4 distributed to the natural air cooling heat exchanger are adjusted. The flow divider valve is arranged to adjust the flow of the cooling medium entering each heating component so as to meet the cooling flow requirements of each component; and meanwhile, more cooling medium pipelines can be added on the basis, so that more flow requirements are met, and the practicability and flexibility of the whole system are improved.
