摘要： PROBLEM TO BE SOLVED: To provide a technology which improves cooling efficiency by making a wick properly adhere to an internal face of a housing wall of a heat pipe.SOLUTION: A heat pipe 2 comprises a wick 4 therein. The wick 4 is joined to a housing wall internal face region which corresponds to a cooling object installation region 3a defined on a housing external face of the heat pipe 2. The heat of a cooling object can be easily transmitted to the wick by joining the wick at the backside of the cooling object installation region at which a temperature becomes high. In other words, the thermal resistance of the heat pipe is lowered. Furthermore, at the circumference of the cooling object installation region 3a, the heat pipe housing wall and the wick are not adhered to each other excessively, so as not to inhibit a flow of a working fluid. The structure above makes compatible a reduction in thermal resistance of the heat pipe and easiness in movement of the working fluid.

摘要： PROBLEM TO BE SOLVED: To provide a self-excited oscillation heat pipe having improved starting characteristics at low temperature.SOLUTION: A self-excited oscillation heat pipe disclosed in the present specification comprises pressure transmission means provided at the middle of a sealed pipe for transferring pressure fluctuation in one side space to the other side space. The pressure transmission means is allowed to have heat transport characteristics different between on one side and on the other side. The heat pipe on one side (first heat pipe) is allowed to have the heat transport amount less than that of the heat pipe on the other side (second heat pipe) and to have the responsiveness at low temperature superior to that of the second heat pipe. The first heat pipe starts up more quickly than the second heat pipe in a low temperature environment, and the oscillation of the first heat pipe is transmitted to the second heat pipe by the pressure transmission means. The transmitted pressure oscillation induces self-excited oscillation of the second heat pipe, and the self-excited oscillation is started more quickly than in the case of the single element second heat pipe. The pressure transmission means is provided in the folding part of the pipe, and the assemblability is excellent.
