貝格斯 Hi-Flow 300G
特點(diǎn)和好處
熱阻抗：0.20°c-in2 / W（@ 25 psi）
抵抗跑步或滴水
一種玻璃纖維載體上的相變復(fù)合材料
高流量300g由導(dǎo)熱55°C相變復(fù)合涂覆在玻璃纖維網(wǎng)。高流量300g設(shè)計(jì)為計(jì)算機(jī)處理器和散熱器之間的熱界面材料。
在相變溫度、高流量300g打濕的熱面和流動(dòng)產(chǎn)生較低的熱阻抗，材料要求的裝配壓力引起的流動(dòng)。高流量300g將抵制滴流
應(yīng)用方法：
1。一方面適用于40°- 50°C散熱。散熱片加熱爐或熱槍40°- 50°C允許的高流量300g墊應(yīng)像膠墊之間。熱沉冷卻到室溫和包裝。
2。適用于20°- 35°C熱沉。高流量300g可應(yīng)用于室溫的熱沉與泡沫輥的援助。該盤位于散熱器和手機(jī)是用來申請(qǐng)30 psi的壓力。
3。自動(dòng)化設(shè)備30 psi的壓力。選擇和自動(dòng)分配單元可以用于高流量300g至室溫的熱沉，鋪放頭應(yīng)該有一個(gè)柔軟的硅橡膠墊，并用30磅的壓力墊轉(zhuǎn)移到20-35°C熱沉。
典型的應(yīng)用包括：計(jì)算機(jī)及外圍設(shè)備.作為熱界面，裸模露需要熱沉

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.
