Area of Science:

• Electronics Engineering
• Thermal Management
• Antenna Technology

Background:

• Active phased array antennas are vital for radar systems but face heat dissipation challenges.
• Miniaturization and microelectronics advancements necessitate improved embedded cooling solutions.
• Effective thermal management is a key barrier to next-generation high-performance antenna development.

Purpose of the Study:

• To design and analyze a novel swept-back fishnet-embedded microchannel topology (SBFEMCT) for enhanced thermal dissipation.
• To investigate the impact of fishnet runner mesh density and layers on thermal performance.
• To provide insights for overcoming thermal bottlenecks in high-performance phased array antennas.

Main Methods:

• Development of SBFEMCT with varying mesh density ratios and fishnet runner layers.
• Establishment of microchannel models for thermal analysis.
• Characterization of chip maximum temperature (Tmax), runner maximum pressure (Pmax), and maximum velocity (Vmax).

Main Results:

• Reduced Pmax to 72.37% and 57.12% at mesh density ratios of 0.5, 0.25, and 0.125.
• Minimal change in maximum velocity observed across different fishnet runner layers.
• Small increase in maximum pressure drop with an increasing number of fishnet runner layers (0 to 4).

Conclusions:

• SBFEMCT demonstrates significant potential for effective heat dissipation in electronic components.
• The study provides valuable data for optimizing microchannel design for thermal management.
• This research offers new references for addressing thermal challenges in advanced phased array antennas.
