Optimization of heat dissipation performance of N-type cold plate for server chips
A server N-type cold plate was taken as the research object,and the influences of multi-factor interaction on the server heat source temperature,cold plate fluid temperature and pressure drop were studied.Based on the response surface method,the performances of cold plate with different inlet temperature,flow rate,thermal conductivity and volume fraction of nanoparticles were analyzed.The results show that the inlet flow rate has a significant effect on each optimization target.The inlet temperature and flow rate have the greatest influence on the heat source temperature,and the inlet temperature and the thermal conductivity of the cold plate have no significant effect on the pressure drop of the cold plate.After optimization,the maximum temperature of the heat source is reduced by 13.01 K,the average temperature is reduced by 6.46 K,and the thermal perform-ance of the cold plate is significantly improved.
