Title:
LOOP-SHAPED HEAT PIPE AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/049752
Kind Code:
A1
Abstract:
An evaporator (110) of a loop-shaped heat pipe comprises: a case (121, 122) which is provided with a fluid inlet and a steam outlet; and at least one porous body (130) which is arranged in the case and through which a liquid-phase working fluid is introduced onto the inner surface of the case. The evaporator (110) additionally comprises a liquid supply tube (140) which is arranged in the case (121, 122) and through which the working fluid is introduced from the fluid inlet to the at least one porous body (130). The liquid supply tube (140) comprises a material having a lower heat conductivity than that of a material that constitutes the case (121, 122). The vaporization of the working fluid that flows into the evaporator (110) can be prevented before the working fluid reaches the porous body (130), and therefore the steady circulation of the working fluid can be achieved.
