Embodiment 1

[0034] Example 1 Lube oil cooler

[0035] Such as figure 1 Shown: the lubricating oil cooler of the present invention includes a radiating plate 7.2 and a one-way valve 7.1 arranged on the lubricating oil delivery pipeline. The radiating plate 7.2 and the one-way valve 7.1 are arranged in parallel, and the one-way valve 7.1 or the lubricating oil delivery pipeline 6 communicating with the one-way valve 7.1 is integrated on the heat sink 7.2. Preferably, the one-way valve 7.1 or the lubricating oil delivery pipeline 6 communicating with the one-way valve 7.1 is integrated inside the heat dissipation plate 7.2, so as to maximize the one-way valve 7.1 or be connected to the one-way valve 7.1 The efficiency of heat transfer from the connected lubricating oil delivery pipeline to the heat sink 7.2. Preferably, it also includes a cooling fan 7.3 for cooling and ventilating the heat sink 7.2, so as to improve the heat dissipation efficiency of the heat sink 7.2. Of course, the cooler...

Abstract

The invention refers to the technical field of wind power and particularly relates to a lubricant cooler, a cooling lubricating system of a step-up gear box, a wind power unit and a low-temperature starting method of the wind power unit. The lubricant cooler of the invention comprises a radiating plate and a unidirectional valve arranged on a lubricant conveying pipeline; the radiating plate and the unidirectional valve are arranged in parallel, and the unidirectional valve and the lubricant conveying pipeline interconnected with the unidirectional valve are integrated on the radiating plate. The lubricant cooler of the invention can solve the problem that the wind power unit of the cooling lubricating system of step-up gear box is shutdown for failure for the lubricant blocks the radiating plate. The cooling lubricating system of the step-up gear box is simple in structure. The wind power unit can be effectively started under low temperature. The low-temperature starting method of the wind power unit can smoothly start the wind power unit under the low-temperature environment.

Description

technical field [0001] The invention relates to the technical field of wind power, in particular to a lubricating oil cooler, a cooling and lubricating system for a speed-increasing gearbox, a wind turbine, and a low-temperature start-up method for the wind turbine. Background technique [0002] The northern region of my country is rich in wind resources and is the current and future major wind power installed capacity market. In the northern region, the temperature is relatively low from November to February of the following year, and the weather conditions below -10°C are relatively frequent, and the temperature in summer is relatively high. Wind turbines in my country are divided into low-temperature type and normal temperature type according to the operating environment temperature: the operating environment temperature of low-temperature type wind turbines is -30°C~40°C, and the operating environment temperature of normal temperature type wind turbines is -10°C~40°C. T...
