Title:

LOOP-SHAPED THIN HEAT PIPE

Document Type and Number:

Japanese Patent JP3695892

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a loop-shaped thin heat pipe capable of performing the most-suitable heat transfer in response to a condition of use and further enable the heat transfer to be carried out more efficiently.
SOLUTION: This thin heat pipe 21 is constructed such that working fluid acting to transfer heat is stored in a loop-shaped thin pipe 25, a part of the loop-shaped thin pipe 25 is used as a heat absorbing part A and then a part other than the heat absorbing part A is used as a thermal radiating part B at a part of the loop-shaped thin pipe 25. In this case, if it is assumed that a heat exchanging length of the heat absorbing part A of the fine pipe is set as l and an inner diameter of the thin pipe 25 at the heat absorbing part A is set as (d), the elements l and (d) satisfy a condition of 15d< l<882d and when a Laplace constant L is set as L=[σ/{(σ1-σv)g}]0.5, the inner diameter (d) satisfies the condition of L<d<3L.
