A submerged liquid-cooled module based on Sunway CPU is studied in the paper.The processor is Sunway SW3231,which realizes the autonomy and control in the domestic field.The way of the heat dissipation is the submerged liquid-cooled method,which solves the shortcomings of the traditional air-cooled method,such as loud noise and large space occupation,saves the power cost and improves the heat dissipation efficiency.This module provides two gigabit Ethernet interface,two 10 gigabit optical interfaces and USB interfaces.It supports health monitoring and management functions,which can monitor voltage and other performance.It can be suitable for unity operating system.The graphical interface can be realized by virtual network console.The module can be applied to signal processing,data processing,network switching,liquid-cooled server and other important fields.
