Design and Develop a Viable Microchannel Approach for Liquid-Liquid Cooling Systems

One of the main concerns in the world is rising energy demand, which forces industries to introduce the products with the lowest energy consumption. Cooling systems often employ single-phase flow and gas-liquid two-phase flow in many applications. These types are well-demonstrated that have lower cooling performance than liquid-liquid two-phase flow. Therefore, customers would pay more as the electricity price goes up. Another pain that customers experience is a higher maintenance cost to keep the product in good condition. Our solution is a new viable liquid-liquid microchannel approach that would provide high cooling performance resulting in a more sustainable cooling system. A unique design for the discharge tank is required to separate both operating liquids in a practical way before pumping through the loop. This novel design would provide a continuous flow of each phase before joining each other at a Tee junction to establish a slug flow. Then, metal lab-on-a-chip microchannels with rectangular cross-sectional areas transfer thermal energy to the coolant. The rectangular cross-section of the channel would also have different aspect ratios to give an optimized cross-section where the highest heat transfer rate occurs.
