贝格斯 Hi-Flow 300G
特点和好处
热阻抗:0.20°c-in2 / W(@ 25 psi)
抵抗跑步或滴水
一种玻璃纤维载体上的相变复合材料
高流量300g由导热55°C相变复合涂覆在玻璃纤维网。高流量300g设计为计算机处理器和散热器之间的热界面材料。
在相变温度、高流量300g打湿的热面和流动产生较低的热阻抗,材料要求的装配压力引起的流动。高流量300g将抵制滴流
应用方法:
1。一方面适用于40°- 50°C散热。散热片加热炉或热枪40°- 50°C允许的高流量300g垫应像胶垫之间。热沉冷却到室温和包装。
2。适用于20°- 35°C热沉。高流量300g可应用于室温的热沉与泡沫辊的援助。该盘位于散热器和手机是用来申请30 psi的压力。
3。自动化设备30 psi的压力。选择和自动分配单元可以用于高流量300g至室温的热沉,铺放头应该有一个柔软的硅橡胶垫,并用30磅的压力垫转移到20-35°C热沉。
典型的应用包括:计算机及外围设备.作为热界面,裸模露需要热沉

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.
