Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • The present invention relates to a heat dissipating device, and more particularly to a flexible heat pipe.
  • 2. Description of Prior Art
  • As information industry develops rapidly, computer devices usually come with an increasingly higher data processing speed, and produce more heats from the electric resistance of electronic components such as CPUs, IC components, power transistors, power supply devices installed in the computer devices during the operation of these electronic components, and thus the temperature of components rises. In addition, as the integrated circuit technology advances and becomes widely used, the electronic devices tend to be developed with a light, thin, compact and high-frequency high-speed design, so that the heat produced per unit area of the densely installed components is increased. If the heat produced by the electronic components is not dissipated properly and timely, a high temperature will result and slow down the execution speed and affect the system safety and performance adversely, and even worse, the heat may damage hardware equipments. To suppress the rise of temperature caused by an excessively large quantity of heat produced during the operation of the electronic components, it is necessary to dissipate the heat by a heat dissipating device. Among various different heat dissipating devices, heat pipe with the features of super silence, high-speed heat conduction, high thermal conductivity, lightweight, compact size, free-of-mechanical parts, and simple structure, is used extensively in the area of dissipating heat of electronic devices.
  • The structure of a conventional heat pipe is a sealed vacuum pipe including a capillary tissue on an internal wall of the pipe, a vapor channel in the middle of the pipe, and a working fluid filled into the vacuum pipe and having a volume equal to the total volume of crevices of the capillary tissue, wherein the working liquid is water, ethanol, acetone or any liquid with the features of a high heat of vaporization, a good mobility, stable chemical properties and a low boiling point. The heat pipe can be divided into an evaporating section and a condensing section according to its functions of absorbing and dispersing heat. If the evaporating section is heated, the working liquid in the capillary tissue will absorb heat and thus the temperature will rise. When the temperature rises to an evaporation point, the temperature will remain at the evaporation point, and the evaporating section will still continue absorbing a large quantity of heat to vaporize the liquid. The vapor under a slight pressure different passes through the channel in the pipe quickly, until the vapor is cooled to a condensation point when it reaches the condensing section. Now, the temperature remains at the condensation point, and a large quantity of heat is discharged, and the heat is conducted through the heat pipe and dissipated to the outside, such that the vapor can be condensed into a liquid to be entered into the capillary tissues, and the liquid in the capillary tissues flows back to the evaporating section by the capillary action to continue transmitting heat by a heat circulation caused by a phase change of the working liquid.
  • The conventional heat pipe is generally manufactured into a cylindrical shape for thermally coupling a heat generating source and a heat dissipating body in order to transmit the heat produced by the heat generating source to the heat dissipating body for heat dissipation. Since the heat generating source and the heat dissipating body are disposed at different positions, and there are other devices installed in a path between the heat generating source and the heat dissipating, therefore the heat pipe must be bent into a required curvature to fit different using conditions in order to avoid other devices or to achieve a connection. However, a mechanical tool is required for bending the heat pipe into the cylindrical shape, and it is common to have discrepancy or even error of the curvature of the heat pipe. As a result, it is necessary to adjust the curvature of the heat pipe by the mechanical tool in an installation. Obviously, the conventional heat pipe wastes time and labor cost for its installation and requires further improvements.
  • In view of the shortcomings of the prior art, the inventor of the present invention based on years of experience in the related field to conduct extensive researches and experiments, and finally developed a flexible heat pipe in accordance with the present invention and provide a feasible effective solution to overcome the shortcomings of the prior art.
