Benefits of technology
The present invention provides an improved heat pipe structure that has better heat transfer performance and is able to achieve excellent heat dissipation effect. The heat pipe structure has two separate chambers for the vapor-phase and liquid-phase working fluids to transfer heat, which greatly enhances heat transfer efficiency.
Problems solved by technology
The conventional heat pipe generally has one single chamber and one single capillary structure so that the heat transfer efficiency of the conventional heat pipe is limited.
The backflow of the liquid will obstruct the vapor from smoothly flowing to deteriorate the heat transfer efficiency.
1. The heat transfer efficiency is poor.
2. The vapor-liquid circulation efficiency of the working fluid is poor.

A heat pipe structure includes a first tubular body and a second tubular body. The first tubular body has a first chamber and a working fluid. A first capillary structure is disposed on outer circumference of the second tubular body. The second tubular body is disposed in the first chamber and has a second chamber. In the heat pipe structure, the vapor-phase working fluid flows within the first chamber, while the liquid-phase working fluid flows within the second chamber in separation from the vapor-phase working fluid. Accordingly, the impedance against the vapor is greatly reduced and the heat transfer efficiency is greatly enhanced to achieve excellent heat dissipation effect.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates generally to a heat pipe structure, and more particularly to an improved heat pipe structure having multiple chambers, whereby the vapor-phase working fluid and the liquid-phase working fluid independently separately flow within different chambers to transfer heat. Accordingly, the heat transfer effect is greatly enhanced to achieve better heat dissipation effect.[0003]2. Description of the Related Art[0004]Following the continuous development of scientific and technical industries, the operation speed and performance of all kinds of electronic components have been continuously enhanced. In the meantime, the waste heat generated by the electronic products has become higher and higher. In the conventional heat dissipation devices, heat pipe is a simple but very effective heat dissipation means. The heat pipe can quickly transfer a large amount of heat via latent heat. The heat pipe has the a...
