摘要:

风电机组变压器内置塔筒是一种新型的布置方式,但不可避免地带来运行发热量大、增加塔筒空气环境温度等问题。鉴于此,采用计算流体动力学(Computational fluid dynamics,CFD)技术对内置变压器的塔筒双层原机械通风散热系统进行了数值模拟研究,通过分析计算结果的速度场和温度场,指出原方案的不足,并在此基础上提出三种递进式优化方案,通过对比原方案和各优化方案的温度计算结果,证明了优化方案的有效性,优化结果满足塔筒环境温度设计要求。

关键词: 变压器内置, CFD, 通风散热

Abstract:

The built-in transformer of wind turbine is a new arrangement, but it inevitably brings problems such as high heat output, increasing air ambient temperature and so on. In view of this, CFD technology is used to study the numerical simulation of the tower drum double-layer original mechanical ventilation and heat dissipation system with built-in transformer. By analyzing the speed field and temperature field of the calculation results, the shortcomings of the original scheme are pointed out. On this basis, three progressive optimization schemes are proposed. By comparing the temperature calculation results of the original scheme and each optimization scheme, the effectiveness of the optimization scheme is proved. The optimization results meet the design requirements of tower ambient temperature.

Key words: Built-in transformer, CFD, heat dissipation
