Liquid metal heat dissipation technology
Liquid metal heat conducting sheet:
Liquid metal heat conducting sheet is a kind of phase change metal sheet thermal interface material, which is used between the heating device and the radiator layer. By using its low melting point characteristics, it melts itself by absorbing the heat of the heating body and fully fills the interface gap to form a good heat conducting channel.
It has ultra-high thermal conductivity and thermal conductivity ≥ 30 w/ (m · K). The product is soft, flexible and easy to cut. The phase transition temperature can be customized to meet different application scenarios. The product is high temperature resistant, non-volatile, non-toxic and environmentally friendly. It can be widely used for heat dissipation of electronic devices in high temperature and high heat flux occasions such as computers, servers, IGBT modules, lasers, etc.
Liquid metal heat conducting paste
Liquid metal conductive paste is a kind of metal paste thermal interface material, which has high thermal conductivity and stability that breaks through the traditional thermal interface materials. Thermal conductivity ≥ 20 w/ (m · K), which is much higher than the limit of 6 w/ (m · K) that conventional silicone oil-based thermal interface materials are difficult to break. Pure metal composition, high temperature resistance above 1000 degrees, no volatilization, making up for the defects of silicone oil-based thermal interface materials that are not high temperature resistant and volatile. It can be widely used for heat dissipation of electronic devices in high temperature and high heat flux occasions such as CPU, GPU and high-power LED.
Liquid metal composite thermal grease:
The thermal conductivity of liquid metal composite thermal conductive silicone grease is ≥ 8 w/ (m · K), and the performance at the thermal resistance end is extremely excellent. At the same time, the problem that liquid metal is easy to leak and corrode other metals is solved. While maintaining high thermal conductivity and high insulation, the product construction process is convenient, greatly enhancing the universal applicability of the product.
Applications:
Compared with the thermal conductive silicone grease used in the previous design of thermal conductive materials, the cost of using liquid metal is much higher. But on the whole, it reduces the total cost of the cooling system. Because if the heat can be well absorbed near the heat source, the cost can not be increased on the heat sink and cooling fan. At the same time, the speed of the cooling fan is also reduced, and the fan noise is also reduced. In terms of cost and mute, liquid metal is a very reasonable design, which has been gradually applied in notebook computers, game consoles and other devices.
Liquid metal has low melting point, is liquid at room temperature, and has high thermal conductivity. It is very effective in transferring heat energy between surfaces such as processor chips and radiators. Different electronic products use different chips and radiators, and their internal structures, shapes and space sizes are different. Appropriate liquid metal materials must be selected according to specific conditions, and corresponding protective structures must be designed.
