[0003] The early water cooling method is a direct current method, which has a low utilization rate of water; the current water cooling method basically adopts a circulating water cooling method. In the circulating water cooling method, the water utilization rate is high, which can be divided into open circulating water cooling. The open circulating water cooling device is prone to pipeline blockage and has been gradually abandoned. The closed circulating water cooling device is not prone to this phenomenon. However, most circulating water cooling devices are now The cooling device cannot automatically adjust the amount of water exchanged with the heat exchanger according to the temperature of the circulating water in real time, so the cooling effect is often poor

Embodiment Construction
[0013] Such as figure 1 As shown, the circulating water pump 1 provides power to promote the continuous circulation of cooling water in the circulating pipeline 12, and the external interface 9 is connected to the heating device. After the cooling water takes away the heat of the heating device at the external interface 9, it passes through the three-way valve inlet 131 Enter the three-way temperature control valve 13. The three-way temperature control valve 13 is composed of a thermostat controller and a valve body. The temperature can be preset on the thermostat controller. The three-way temperature control valve 13 can be adjusted according to the comparison between the water temperature and the preset temperature. As a result, the ratio of the water flow out of outlet 133 and outlet 132 is automatically adjusted. The outlet 133 is connected to the external interface 10, the external interface 10 is connected to a heat exchanger, and the outlet 132 is connected to the degass...

Description
technical field [0001] The invention relates to a circulating cooling device for a wind-driven double-fed generator. Background technique [0002] A large amount of heat will be generated during the operation of the wind doubly-fed generator. If it is not cooled in time, the stability of its operation will be disturbed. The current cooling method is mainly water cooling. [0003] The early water cooling method is a direct current method, which has a low utilization rate of water; the current water cooling method basically adopts a circulating water cooling method. In the circulating water cooling method, the water utilization rate is high, which can be divided into open circulating water cooling. The open circulating water cooling device is prone to pipeline blockage and has been gradually abandoned. The closed circulating water cooling device is not prone to this phenomenon. However, most of the circulating water cooling devices now The cooling device cannot automatically ...
