Study of PCM-based pin-fin heat sinks Academic Article uri icon

abstract

  • ABSTRACT This study deals with heat transfer from pin-fin aluminum heat sinks to a phase- change material (PCM) which fills the inter-fin space. The sinks have a horizontal base and accordingly their fins are vertical. The sink base dimensions are 100 mm by 100 mm, with fin height of 10 mm, 20 mm or 30 mm, and cross section of 4 mm× 4 mm. The number of fins varies, eg 49, 64, 81, etc. The applied power is between 50 W to 250 W, corresponding to the heat fluxes of 5-25 kW/m2. The present paper reports mostly numerical results, but the …
