To provide a loop-type heat pipe and an electronic apparatus with the loop-type heat pipe excellent in startability and heat transport capacity.
The loop-type heat pipe 10 includes a compensation chamber 11, an evaporating part 12, a steam pipe 13, a condensing part 14 and a liquid pipe 15 connected in a loop-shape, and a working fluid is circulated therein. A working fluid absorbing member 16 discharging the working fluid 18 to shrink at a temperature higher than a predetermined temperature and absorbing the working fluid 18 to expand at a temperature lower than the predetermined temperature is provided in the compensation chamber 11. Even when the loop-type heat pipe 10 is placed in top heat arrangement and the working fluid flows out of the evaporating part, the working fluid 18 required for wetting a wick 22 is supplied from the working fluid absorbing member 16 by heating at a starting time, the circulation of the working fluid can be started. Further, since there is no need to provide a porous filter with large flow resistance in a passage of the working fluid, heat transport characteristics are also excellent.
