Wind power generation refers to converting kinetic energy of wind into electric energy, wind energy is a clean and pollution-free renewable energy source, and wind power generators are gradually popularized in life and production. In order to reduce the friction loss generated when the internal mechanical components of the wind turbine operate, a lubricating system for injecting lubricating oil is generally installed in the wind turbine, and the temperature around the wind turbine is changed greatly because the wind turbine is located at a high position. The oil storage tank for storing lubricating oil in the traditional lubricating system does not have the temperature regulation function, and the temperature of the lubricating oil is greatly influenced by the ambient temperature of the unit, so that the lubricating oil in the oil storage tank cannot be kept at the proper working and storage temperature, and the normal operation of the lubricating system is influenced.
When the ambient temperature of the unit is high, the temperature of the lubricating oil in the oil storage tank rises, the lubricating oil can be slowly oxidized and blackened at high temperature, and finally the oxide can not be dissolved in the lubricating oil seriously and is deposited at a certain position of the system by a brown slime layer, so that the control oil passage in the oil pump is easily blocked, and the normal operation of the lubricating system is influenced. And along with the rise of the temperature, the viscosity of the lubricating oil is reduced, an oil film is difficult to establish, and the lubricating effect on mechanical parts in the wind driven generator is reduced.
When the ambient temperature that the unit was located is lower, the temperature of lubricating oil in the oil storage tank also reduces thereupon, and along with the reduction of temperature, the viscosity of lubricating oil increases, and the great lubricating oil of viscosity gets into just more of piston ring district, piston skirt portion and the glued membrane that the inner chamber generated in the oil pump, and the intermittent type has increased the power of oil pump, has accelerated the loss of oil pump.
In view of the above, it is necessary to provide a temperature control device for controlling the temperature of an oil storage tank in a wind turbine generator and a wind turbine generator, in order to solve the problem that the temperature of the lubricating oil in the oil storage tank in the wind turbine generator cannot be maintained at an appropriate working and storage temperature.

In some embodiments, the upper limit of the suitable temperature range for the lubricating oil is 70 deg.C, and n-ethane having a boiling point of 68 deg.C may be used for the first fluid 624.
The temperature control mechanism 6 includes a control box 61 capable of conducting heat, and is disposed on the oil storage tank 1, and the control box 61 has a second cavity and a second control assembly 63 disposed in the second cavity.
