Description

technical field [0001] The invention relates to the technical field of computer chip heat dissipation, in particular to a liquid cooling heat dissipation system. Background technique [0002] In recent years, the key problem of thermal barrier of highly integrated computer chips has become one of the technical bottlenecks restricting its sustainable development. At present, the mainstream technology development direction to solve the high-power consumption and high-density heat dissipation of computer chips is to develop liquid cooling methods, and use coolant to enhance the heat dissipation effect of chips. There have been a large number of research reports on water-based coolant technology and liquid metal heat dissipation technology, and some progress has been made in the experimental research and application of chip cooling, but there are still serious bottlenecks in meeting product application requirements.

Problems solved by technology

There have been a large number of research reports on water-based coolant technology and liquid metal heat dissipation technology, and some progress has been made in the experimental research and application of chip cooling, but there are still serious bottlenecks in meeting product application requirements. For example: water-based coolant is mainly The boiling point is low, and bubbles will be generated at the heat exchange interface, which will evaporate and cause heat loss and heat resistance, which will lead to corrosion and overheating of the device. In addition, it is not conducive to miniaturization. When the temperature is below zero, it will freeze and expand; while the liquid state Alternative materials for metal cooling liquid are very scarce. Gallium, which is expensive and scarce in resources, is the main cooling liquid component. When the temperature is lower than the melting point of gallium (29.77°C), it will phase-transform into a solid and expand, thus affecting the flow of the pipeline. The requirements are extremely high, and its reliability needs to be improved
