本文新设计的纤维干道吸液芯热管,液体传输和传热性能高,热管工作特性有满意的再现性和制作工艺上的仿制性。这种大功率硅元件用风冷热管散热器经过热性能试验,同硅元件匹配进行动态、半动态试验,振动和冷热循环等一系列试验表明,完全符合设计要求。热管散热器的热阻、重量、尺寸等主要性能指标,已赶上国外同类热管散热器的研制水平。文中还提供了热管变工况下的一系列热性能试验数据,对于应用有重要的实际意义。热管散热器的研制成功,为高压、大电流硅元件的风冷散热开辟了新的途径。
In this paper, the new design of the fiber channel capillary wick heat pipe, high liquid transport and heat transfer performance, heat pipe working characteristics have satisfactory reproducibility and production process of the imitation. This high-power silicon components with air-cooled heat pipe radiator heat performance test, with the matching silicon components for dynamic, semi-dynamic test, vibration and thermal cycling and a series of tests show that fully meet the design requirements. Heat pipe heat sink resistance, weight, size and other major performance indicators, has caught the same level of foreign heat pipe radiator development. The article also provides a series of thermal performance test data under the condition of heat pipe change, which has important practical significance for the application. The successful development of the heat pipe radiator has opened a new avenue for the air cooling of the high voltage and high current silicon components.
