LOOP-TYPE HEAT PIPE AND ELECTRONIC DEVICE INCLUDING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a loop-type heat pipe and an electronic device including the same, superior in starting performance and a heat transporting capacity.;SOLUTION: This loop type heat pipe 10 includes: a compensation chamber 11 for storing working liquid 18; an evaporating section 12 receiving heat from the external and evaporating the working liquid 18; a steam pipe 13 for guiding the steam of the evaporating section 12 to a condensing section 14; the condensing section 14 radiating heat to the external and condensing the steam; a liquid pipe 15 for guiding the condensed working liquid 18 to the compensation chamber 11; and a wick 22 partitioning a working liquid flow channel 22b communicated with the compensation chamber 11 and a steam flow channel 22b communicated with the steam pipe 13 in the evaporating section 12. In the loop type heat pipe 10, a spacer 16 is disposed movably between the compensation chamber 11 and the working liquid flow channel 22b, and moved into the working liquid flow channel 22b to reduce a volume of the working liquid flow channel 22b when the heat pipe is disposed in a state that a position of the evaporating section 12 is higher than a position of the condensing section 14.;COPYRIGHT: (C)2011,JPO&INPIT
