Comprehensive Review on Heat Transfer Enhancement by Using Porous Baffles in a Duct
Subscribe/Renew Journal
The present scenario in design of electrical/electronic component is getting more compact sizes, which results in heat generation. This excessive heat generation will reduced the life of component. To overcome this problem there is a need of effective cooling system. Extended surface heat sink is popularly used heat sink technique. To improve efficiency of it there is number of conventional methods available but only few methods such as changing the shape of the baffle cross section, changing the arrangement of the baffles and its inclination with walls and using high conductivity metallic foam (aluminum foam) material has got good result individually. Metallic foam baffles are enhancing the heat transfer rate as compare to the solid baffle. Pressure drop across the channel is less if comparing with solid one. The turbulence occurred due to porosity is good enough to increase the rate of heat transfer. This article is based on comprehensive review of work carried out in this technology.
