With the rapid advancement of chip technology and the continuous improvement of chip performance, heat dissipation during testing is becoming increasingly severe. Liquid cooling systems for chip testing, with their many unique features, have become a key solution to chip heat dissipation challenges, providing strong support for the development of the chip industry.
With the rapid advancement of chip technology and the continuous improvement of chip performance, heat dissipation during testing is becoming increasingly severe. Liquid cooling systems for chip testing, with their many unique features, have become a key solution to chip heat dissipation challenges, providing strong support for the development of the chip industry.
Liquid cooling systems for chip testing offer highly efficient heat dissipation. Liquids have a thermal conductivity 25 times that of air, a volumetric specific heat capacity 1,000 to 3,500 times that of air, and a convective heat transfer coefficient 10 to 40 times that of air. For example, the ERS high-power liquid cooling chuck system provides precise temperature management for devices under test when testing complex embedded processors and highly parallel devices. It can dissipate up to 2500W of power (300mm wafers) at -40°C, while maintaining an industry-leading temperature uniformity of ±0.2°C.
Energy efficiency is also a key advantage. Traditional air cooling systems require a large number of fans to maintain temperatures, resulting in high energy consumption. Liquid cooling systems, however, can significantly reduce energy consumption. For example, cold plate liquid cooling systems can eliminate the need for computer room air conditioning, reducing the system's power usage effectiveness (PUE) to below 1.08. Actual data from a supercomputing center shows that the pump power of this liquid cooling system accounts for less than 5% of total energy consumption. Liquid cooling systems for chip testing also offer excellent compatibility. Some liquid cooling systems can retain the original server architecture, requiring only modifications to the heat dissipation module. For example, cold plate liquid cooling simply replaces the original air-cooled heat sink with a liquid cooling kit and routes the refrigerant piping out of the chassis. This requires minimal modification to the computer system and is suitable for cooling medium-to-high heat flux densities. Furthermore, some liquid cooling systems offer flexible scalability. Through modular Cooling Distribution Unit (CDU) designs, data centers can gradually upgrade their cooling infrastructure without major facility renovations. CDUs come in a variety of types, including rack-mount, row-mount, and facility-mount, allowing for flexible deployment based on diverse needs.
Liquid cooling systems are also relatively environmentally friendly. Unlike traditional evaporative cooling, liquid cooling systems often utilize a closed-loop coolant circulation system, minimizing water consumption. For example, direct-to-chip cooling (D2C) systems utilize a closed-loop circulation system, effectively conserving water resources and further aligning with environmental protection principles.
As chip performance continues to improve and heat dissipation requirements continue to increase, these characteristics of chip testing liquid cooling systems will play an increasingly important role in the chip testing field, driving the chip industry towards higher performance and more energy-efficient development.
