摘要

Having advantages of the loop thermosyphon and those of gravity heat pipe combined to design a loop thermsyphone was implemented.Basing on the experiments,the heat transfer performance of loop thermo syphons with different structures was analyzed to show that,the heat transfer performance of type A loop thermosyphon outperforms that of the type B;and different tilt directions have little effect on the two loop thermosyphons.Simulating tooth-shaped fin's influence on the loop thermosyphon shows that,the tooth-shaped fin can effectively enhance the natural convection heat transfer and increase the heat transfer power of the loop thermosyphon.%将回路型热管和重力热管的优点相结合,设计了回路型重力热管.通过试验的方法分析两种不同结构的回路型重力热管的传热性能,结果表明:A型回路型重力热管的传热性能优于B型,不同的倾斜方向对两种回路型重力热管几乎没有影响.通过数值模拟的方法研究了齿形翅片对回路型重力热管的影响,结果表明:齿形翅片可以有效强化自然对流传热,增加回路型重力热管的传热功率.
