Benefits of technology

[0013]The present invention further has the following effects. The invention uses the annular elastomer to support the soft encapsulating layer, so that the soft encapsulating layer will not sink or collapse easily. With each receiving section of the soft encapsulating layer sheathed onto each heat pipe tightly, a quick heat conduction effect can be achieved. Since the flexible material of the heat pipe allows the heat pipe to be adjusted and bent to any angle, the heat pipe will not be hardened easily and the integrity of its original structure will remain even after the pipe has been adjusted and bent repeatedly for many times.

Problems solved by technology

Obviously, the use of a heat sink composed of a plurality of heat dissipating fins and a fan in the past no longer meets the requirement of the high-speed operation of the present CPUs.
However, existing heat pipes still have a drawback of occupying much space, and thus it is a main subject for related manufacturers and developers to improve the conventional heat pipes.
However, the interior of the wick structure and the internal wall of the metal tube body of the bent heat pipe may be peeled of or fallen off easily, so that the heat conduction effect is reduced significantly.
Furthermore, most of the foregoing heat pipes can be bent once only in the manufacturing process, and a second bend of the heat pipe may crack the metal tube body easily.

Abstract

In a flexible heat pipe and a manufacturing method thereof, the flexible heat pipe includes a first tube body, a second tube body arranged apart from the first tube body, a flexible section, a wick structure, and a working fluid. The flexible section includes an annular elastomer and a soft encapsulating layer. The annular elastomer connects the first tube body and the second tube body. The soft encapsulating layer is set around the annular elastomer. The capillary structure is settled inside the first tube body, the second tube body, and the annular elastomer. The working fluid is filled inside the first tube body, the second tube body, and the soft encapsulating layer. Then, the flexible heat pipe can be bent to any angle or in any direction according to practical demands.

Description

FIELD OF THE INVENTION[0001]The present invention generally relates to heat pipes, in particular to a flexible heat pipe and a manufacturing method of the flexible heat pipe.BACKGROUND OF THE INVENTION[0002]As computer components such as a central processing unit (CPU) come with an increasingly higher computing speed, the heat generated by the components also becomes increasingly greater. Obviously, the use of a heat sink composed of a plurality of heat dissipating fins and a fan in the past no longer meets the requirement of the high-speed operation of the present CPUs. Therefore, some manufacturers developed a heat dissipating device that combines a heat pipe with heat dissipating fins to overcome the heat dissipation problem of the present CPUs. However, existing heat pipes still have a drawback of occupying much space, and thus it is a main subject for related manufacturers and developers to improve the conventional heat pipes.[0003]In general, a conventional heat pipe comprises...
