贝格斯HF105相变界面材料

 Hi-Flow 105系列参数

特点和好处

        热阻抗0.37°c-in2 / W（@ 25 psi）

        用于电气隔离不是必需的

        波动性低，不到1%

        在制造环境中容易处理

        流，但不象油脂

        Hi-Flow 105是一个在铝基片的两面涂的相变材料。它是专门设计，以取代油脂作为热界面，消除了混乱，污染和难以处理与油脂。Hi-Flow 105是在室温下的粘性和耐刮伤，不需要在装运时的一个热沉的保护套。

        在65°C（相变温度），Hi-Flow 105从固体和流动的变化，从而保证总湿了界面。Hi-Flow 105的触变特性降低泵的出接口。

        高流量105热性能等于油脂0.10°c-in2 / W的接触热阻。

典型的应用包括

        功率半导体

        安装在散热片上的微处理器

        功率转换模块

        弹簧或夹子安装使用的热润滑脂

 配置可用

        板材形式，模切件和轧辊形式

        带或不带压敏胶

1)  This is the measured thermal conductivity of the Hi-Flow coating. It represents one conducting layer in a three-layer laminate. The Hi-Flow coatings are phase change compounds. These layers will respond to heat and pressure induced stresses. The overall conductivity of the material in post-phase change, thin film products is highly dependent upon the heat and pressure applied. This characteristic is not accounted for in ASTM D5470. Please contact Henkel Product Management if additional specifications are required.  2) The ASTM D5470 test fixture was used and the test sample was conditioned at 70°C prior to test. The recorded value includes interfacial thermal resistance. These values are provided for reference only. Actual application performance is directly related to the surface roughness, flatness and pressure applied.
