Abstract:A novel flat heat pipe for notebook PC cooling is put forward, which has
   the features of high efficiency of heat dissipation, high mechanical
   strength, light weight, low cost, convenient manufacture. The
   experimental investigation on thermal performance of the flat heat pipe
   in natural convection cooling is made. The startup performance and
   temperature uniformity of the flat heat pipe and the effects of heat
   load and tilt angle on the thermal characteristics are also analyzed.
   For performance comparison, the experimental investigation is also
   carried out on an aluminum block of the same dimensions. It is found
   that compared with the aluminum block, the flat heat pipe is superior in
   heat transfer performance. When the heat load is 17 W, the total thermal
   resistance of the flat heat pipe radiator is 1. 72 ℃/W, the maximum
   temperature of condensing surface is 49. 7 ℃, and the heat source
   temperature is 55. 3 ℃, which meets the demand of heat dissipation for
   notebook PC.
