    摘要: A thermal interface material is for being applied to the contact surfaces to eliminate the air interstices between the heat dissipating apparatus and the electronic component in order to improve heat dissipation of the electronic component. The thermal interface material includes pentaerythritol oleate as base oil and fillers filled in the pentaerythritol oleate for improving the heat conductivity of the thermal interface material. The pentaerythritol oleate is used for holding the fillers therein and filling the air interstices to achieve an intimate contact between the heat dissipating apparatus and the electronic component. The fillers include aluminum powders, zinc oxide powders and zinc oxide nano-particles.

    摘要: A silicone grease composition includes approximately 5 to 50% by weight of liquid organopolysiloxane, 45 to 94.9% by weight of a thermally conductive filler, and 0.1 to 5% by weight of a coupling agent chosen from at least one of a titanate-based coupling agent and an aluminate-based coupling agent. Due to the presence of the coupling agent, the silicone grease composition has a relatively lower viscosity and thus is capable of containing a larger amount of the filler whereby the thermally conductive efficiency of the composition is accordingly improved.

    摘要: A heat pipe (10) includes a pipe body (20) having an inner wall (22) and a screen mesh (30) disposed on the inner wall of the pipe body. The screen mesh is in the form of a multi-layer structure with at least one layer thereof having an average pore size different from that of the other layers. The layer with large-sized pores is capable of reducing the flow resistance to the condensed fluid to flow back, whereas the layer with small-size pores is capable of providing a relatively large capillary pressure for drawing the condensed fluid from the condensing section to the evaporating section.
