Popis: The new design of passive cooling device for box TV is investigated. Experimental measurements of different architecture of miniature heat pipes including flat porous heat pipe, cylindrical micro-grooved and porous heat pipes are presented. The heat pipes temperatures distributions are measured for different working fluid filling ratios. Once the optimal volume is obtained and fixed, tests are carried out to evaluate the thermal performance of the heat pipes by measuring evaporator, adiabatic and condenser temperatures within various heat fluxes. Results, after being analyzed, discussed and compared, show that the flat porous heat pipe is the most effective for heat dissipation. This heat pipe is integrated in a box TV instead of conventional forced air cooling device. The flat heat pipe cooling performance is explored using deionized water. Results show that the heat pipe passive cooling device well cooled the box TV electronic components compared to fans cooling mode and the CPU operating temperature remains lower than its limit value.
