摘　　要：通过对特殊型"Ω"形槽道热管(长2200mm,经过3次弯曲)进行测试,探究其启动和传热特性。研究表明,当热管常温启动后,冷端不做控温,热端输入一定热量,冷热两端温差保持在2K以内,热管传热性能优异;此热管若要正常工作,其最低工作温度为-15℃左右,热端最大输入功率为10W左右,此时的传热热阻为0.156K·W^(-1)。随着热沉温度的降低,热阻越来越大;随着倾斜角度的变大,热阻越来越小。此热管具有一定的传热性能。Aiming at special "Ω"-shaped grooved heat pipe with a length of 2200 mm and have three bends, it made tests to explore the characteristics of starting and heat transfer. Research shows that when the heat pipe starts at room temperature, not controling the temperature in the cold end and inputting a certain amount of heat in the hot end, temperature difference keeps within 2 K and the heat pipe has excellent heat transfer performance;in the condition of normal working, the minimum temperature is about-15℃ and the maximum input power is about 10 W, then the thermal resistance is 0.156 K·W-1. With the decrease of heat sink temperature, thermal resistance increases gradually;with the increase of inclination angle, thermal resistance decreases gradually. The heat pipe has certain heat transfer performance.
