Numerical analysis of split-type cold-plate for enhanced heat transfer in missiles
Source abstract
Abstract
Addressing the challenge of sharply increasing heat flux density due to spatial constraints in missile launch platforms and high-power integrated packaging modules, this paper proposes a novel split-type cold-plate (ST-CP) to achieve efficient thermal management via liquid cooling technology. Utilizing the mathematical expression defining the diverter hole size, diverter hole structure parameters are optimized using COMSOL Multiphysics 3.5a software. Compared to a traditional rectangular channel cold-plate, the ST-CP demonstrates significant advantages in temperature uniformity and heat dissipation efficiency, achieving a maximum temperature reduction of 15% and a 30% improvement in temperature uniformity. Furthermore, a mathematical model correlating the volume flow rate and flow resistance of the ST-CP is fitted, providing a design basis for engineering applications. The results solve the thermal dissipation problem for high-power density equipment and offer a new solution for enhancing heat dissipation uniformity.
