Abstract
This paper reports an experimental study around a module about forced air flow by blower (35 × 35 x× 6mm³) in a portable personal computer model(200 × 235 × 10mm³). Experimental report is to know three data to investigate thermal resistance, adiabatic wall temperature and visualized fluid flow around the module by combination of the moving number and the arrangement method of blower. The channel inlet flow velocity has been varied between 0.26, 0.52 and 0.78m/s, and input power (Qp) to the module is 4W. To investigate thermal resistance, the heated module is mounted on two boards(110 × 110 × 1.2mm³ , k=20.73, 0.494W/m °C) in parallel-plate channel to forced air flow. The temperature distribution were visualized by heated module on acrylic board(k=0.262W/m °C) using liquid crystal film. Fluid flow around the module were visualized using particle image velocimetry system.br/
