Key Features<\/strong><\/h2>\n

The key characteristic of thermal grease is that it fills the microscopic voids between solid interfaces and displaces air\u2014which has low thermal conductivity\u2014thereby significantly reducing the contact thermal resistance. Essentially, it is an insulating interface material with a high thermal conductivity, good thixotropy and long-term reliability. It does not rely on its own high thermal conductivity to replace the connection between the heat source and the heat sink; rather, it utilises its paste-like form to wet the interface without exerting excessive pressure, thereby forming a highly efficient thermal conduction pathway at the thinnest possible thickness.<\/p>\n

<\/h2>\n

Typical Use Cases<\/strong><\/h2>\n

\u2705\u00a0Computer and Server Hardware<\/strong>: The filling of the interface between the CPU\/GPU and the heat sink is the most widely recognised application.<\/p>\n

\u2705\u00a0High-Power Power Supplies and Power Electronics<\/strong>: Heat transfer between high-heat-generating semiconductors, such as IGBT modules and MOSFETs, and heat sinks in variable-frequency drives, inverters and UPS systems.<\/p>\n

\u2705\u00a0LED Lighting and Displays<\/strong>: The thermal coupling between the aluminium substrate of the LED chip and the luminaire\u2019s heat sink housing determines light decay and service life.<\/p>\n

\u2705\u00a0Automotive Electronics<\/strong>: Thermal management for the main chips and power modules of the on-board charger (OBC), DC-DC converter and domain controller.<\/p>\n

\u2705\u00a0Consumer Electronics<\/strong>: Heat transfer between the main processing chips in devices such as smartphones, tablets and routers, and the shielding covers, copper heat pipes or mid-frames.<\/p>\n

\u2705\u00a0Domestic appliances<\/strong>: The connection between heat-generating components\u2014such as power transistors in induction hobs and inverter modules in air conditioners\u2014and heat sinks.<\/p>\n

\u2705\u00a0Communications Base Stations and Optical Modules<\/strong>: Heat dissipation from laser components in base station power amplifier modules and high-speed optical modules.<\/p>","protected":false},"excerpt":{"rendered":"

Thermal grease is a paste-like thermal interface material produced by grinding and compounding a base oil of speciality silicone oil with inorganic fillers that offer high thermal conductivity and high-temperature resistance. Its fundamental design principle is not to act as the primary heat conductor itself, but rather to utilise its soft, paste-like consistency to to fully fill the microscopic depressions and gaps\u2014invisible to the naked eye\u2014between the heat-generating component and the heat sink under assembly pressure. This displaces the air\u2014which has a thermal conductivity of only approximately 0.026 W\/(m\u00b7K)\u2014thereby establishing a highly efficient heat transfer pathway based on the material\u2019s own thermal conductivity, and consequently significantly reducing the interfacial thermal resistance.<\/p>","protected":false},"featured_media":1012,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[15,21],"product_tag":[],"class_list":["post-1000","product","type-product","status-publish","has-post-thumbnail","product_cat-pro","product_cat-yjgjxl","first","instock","shipping-taxable","product-type-simple"],"yoast_head":"\n\u5bfc\u70ed\u7845\u8102 -
