A structure of a loop-type heat pipe is disclosed in which a heat carrying fluid, preferably a bi-phase non-condensative fluid, circulates in a loop form in itself under its own vapor pressure at a high speed within an elongate pipe so as to repeat vaporization and condensation, thus carrying out a heat transfer. A structure of the loop-type heat pipe includes the elongate pipe, both ends thereof being air-tightly interconnected to form a loop-type container, the heat carrying fluid, at least one heat receiving portion and at least one heat radiating portion, both being placed at given portions of a elongate pipe, and at least one check valve for limiting a stream direction of the heat carrying fluid. A check valve(s) propels and amplifies forces generated by the heat carrying fluid and its vapor to move toward the stream direction limited by the check valve(s) so that the heat carrying fluid circulates in the stream direction through the closed-loop passage defined by the elongate pipe at the high speed, repeating vaporization at the heat receiving and radiating portions.

A structure of a loop-type heat pipe, comprising: (a) a continuous elongate tube of continuous capillary dimension having both ends thereof air-tightly connected to each other to form a continuous capillary loop-type flow passage; (b) a heat carrying fluid within the elongate tube in an amount sufficient to allow flow of the fluid through the loop flow passage in a closed state defined by the elongate tube; (c) at least one heat receiving portion located on a first part of the elongate tube for heating the fluid therein; (d) at least one heat radiating portion located on a second part of the elongate tube for cooling the fluid therein; and (e) flow control means located within the loop-type flow passage for limiting flow of the heat carrying fluid to a single direction in the flow passage, the flow control means together with mutual actions of vapor pressure generated due to the vaporization at the heat receiving portion and attracting force generated due to condensation of vapor at the heat radiating portion providing propelling force and amplifying the propelling force for the heat carrying fluid so as to circulate the heat carrying fluid in the single direction in the flow passage from the heat receiving portion to the heat radiating portion.
