The peripheral dimension of the evaporating section is larger than the peripheral dimension of each of the condensing sections. The mesh is contained in the step pipe and located inside the evaporating section and the condensing sections. The supporting component is contained in the step pipe and wrapped in the mesh. The combination of these structures increases air's flow rate inside the heat pipe and improves the heat pipe's heat conduction efficiency.
Description
- 1. Technical Field
- The present invention generally relates to a heat pipe, and more particularly, to a method of manufacturing a heat pipe and a heat pipe thereof.
- 2. Related Art
- The exacerbating problems caused by electronic heat sources can be resolved by using heat pipes to dissipate heat in electronic products. Replacing cooling structures formed by cooling fins with heat pipes is apparently the future development trend. In addition to fit in with the premises that electronic products need to be light, thin, short, and small, it's also desirable to further enhance a heat pipe's heat-conduction efficiency.
- A conventional heat pipe generally includes a round pipe with a fixed diameter, a capillary structure, and a working fluid. The round pipe has a containing chamber in its interior. The capillary structure is set inside the containing chamber and stuck to the inner surface of the pipe. The working fluid is filled in the containing chamber and accumulated in the capillary structure. As a whole, these parts form a conventional heat pipe.
- However, because the diameter of the round pipe is fixed, the inner working fluid could not speed up the heat dissipation rate when it evaporates. Therefore, the heat pipe's heat conduction efficiency is relatively limited. Furthermore, because the capillary structure is a homogeneous structure, its flow-back rate is relatively low and hence might not prevent the heat pipe from drying out. In addition, because the heat pipe's evaporation section has a small sectional area, the heat pipe cannot provide a large area to contact with the heat source. Therefore, the heat pipe can only generate a small amount of steam, and the amount is insufficient to prevent heat accumulation. As a result, it's difficult to effectively improve the conventional heat pipe's heat dissipation efficiency.
- Embodiments of the present invention provide a method of manufacturing a heat pipe and a heat pipe thereof. Because in each of the embodiments the peripheral dimension of an evaporating section is different from the peripheral dimensions of a plurality of condensing sections, the embodiments can increase air's flow rate inside the heat pipe and improve the heat pipe's heat conduction efficiency.
- An embodiment of the present invention provides a method of manufacturing a heat pipe. The method includes the following steps: a) providing a hollow pipe, a mesh, and a supporting component, wrapping the supporting component with the mesh and then inserting the supporting component and the mesh into the hollow pipe; b) inserting an insertion rod into the step pipe and letting the insertion rod contact the supporting component; and c) after step b) shrinking a part of the hollow pipe and the insertion rod so as to convert the hollow pipe into a step pipe having varying peripheral dimensions.
- Another embodiment of the present invention provides a heat pipe. The heat pipe includes a step pipe, a mesh, and a supporting component. The step pipe has an evaporating section and two condensing sections. The two condensing sections are on two ends of the step pipe, respectively. The evaporating section lies between the two condensing sections. The inner spaces of the two condensing sections and the evaporating section are interconnected. The peripheral dimension of the evaporating section is larger than the peripheral dimension of each of the condensing sections. The mesh is contained in the step pipe and located inside the evaporating section and the two condensing sections. The supporting component is contained in the step pipe and wrapped in the mesh.
- The embodiments have the following advantages. The composite capillary structure in each of the condensing sections improves the liquid flow-back rate and hence prevents dry out. The relatively larger sectional area of the evaporating section increases the contact area between the evaporating section and a heat source, allows more steam to be generated, and hence improves the heat dissipation efficiency. Because the sectional area of the evaporating section is larger than the sectional areas of the condensing sections and because sectional area is inversely proportional to flow rate, when the working fluid receives enough heat and evaporates, the resulting air will have a higher flow rate.
- It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.
