Heat Dissipation Performance Comparison of Multi-structural Micro-channel Liquid Cold Plates
The micro-channel cold plate,as an effective thermal management device,has been widely utilized in the thermal management of high heat flux electronic devices.In this paper the micro-channel cold plates with channel characteristic dimensions of 2 mm in serial,parallel and jet impingement/micro-channel configurations are studied to explore the differences of their ultimate heat dissipation performances and flow resistance losses.The research findings indicate that under the same cooling fluid flow conditions,the heat dissipation power arrangement in descending order of three cold plates is sequentially serial channels,jet impingement/micro-channels and parallel channels.The internal flow resistance loss of the serial channel cold plate is significantly higher than the other two.By comprehensively considering pressure loss and thermal performance,selecting an appropriate cold plate structure according to different heat source heat flux density conditions holds promise in meeting the specific application requirements.This study provides reference for the design and optimization of micro-channel liquid cold plates.
