Experimental investigations of manifold structure on cooling performance in embedded microfluidic cooling

For embedded microfluidics cooling, the morphology of the microfluidics structure and the liquid injection mode have a great impact on the cooling performance. Manifold structure can adjust the flow direction of the coolant before heat convection, reducing pumping power and improving cooling efficiency of embedded cooling. In this work, four manifold structures for embedded cooling are designed and fabricated, the cooling performance and hydraulic performance of different structures is compared through experimental investigations. The results show that compared with the horizontal cooling, the manifold structure based on vertical cooling not only reduces the temperature by 20.8%, but also reduces the pressure loss by 43.5%.
