Problems solved by technology

However, the known cylindrical heat pipes are too thick to be installed in today's portable computers, so thin heat pipes need to be used instead
[0003] However, it is known that the width of the thin heat pipe is relatively wide and the thickness is relatively thin, so that the central area of ​​the thin heat pipe is prone to depression, resulting in damage to the thin heat pipe.
In addition, the capillary structure of the heating end of the thin heat pipe is insufficient, which causes the dry out phenomenon of the heating end of the heat pipe, which in turn affects the performance of the heat pipe

Embodiment Construction

[0025] figure 1 It is a perspective view of the thin heat pipe 1 of the present invention, figure 2 It is a longitudinal sectional view of the thin heat pipe 1 of the present invention. The thin heat pipe 1 includes a pipe body 10 , a main capillary structure 20 , a first capillary structure 30 and a second capillary structure 40 . The tube body 10 is a flat sealing structure. The width of the pipe body 10 may be three times, four times, or more than five times the thickness of the pipe body 10 . The tube body 10 may have a first outer plane S1 and a second outer plane S2, and the first outer plane S1 is parallel to the second outer plane S2. The tube body 10 may include heat-conducting materials such as metal, and extends along an extending path R1. In this embodiment, the extension path R1 is a straight line and extends along an extension direction D1. In another embodiment, the extending path R1 may include a straight section and / or a curved section.

Abstract

The invention provides a thin type heat pipe, which comprises a pipe body, a main capillary structure, a first capillary structure and a second capillary structure, wherein the pipe body is provided with a hollow cavity and a communication cavity communicated with the hollow cavity, the hollow cavity extends along an extending path, the main capillary structure is arranged in the hollow cavity and extends along the extending path, the first capillary structure is arranged at the side surface of the main capillary structure and is provided with a first passage parallel to the extending path, the second capillary structure is arranged at the other opposite side surface of the main capillary structure and is provided with a second passage parallel to the extending path, the communication cavity is communicated with the first passage and the second passage, the main capillary structure is positioned between the first passage and the second passage, the hollow cavity is provided with an upper surface and a lower surface opposite to the upper surface, and in addition, the main capillary structure, the first capillary structure and the second capillary structure are arranged on the upper surface and the lower surface. The thin type heat pipe has the advantages that the intensity of the heat pipe can be enhanced, and in addition, the dry phenomenon of the heat pipe can be prevented.

Description

technical field [0001] The present invention mainly relates to a heat pipe, especially a thin heat pipe. Background technique [0002] Currently, portable computers such as notebook computers and tablet computers are all developing toward thinning. However, the known cylindrical heat pipes are too thick to be installed in today's portable computers, so thin heat pipes need to be used instead. [0003] However, the known thin heat pipe has a wide width and a relatively thin thickness, so that the central area of ​​the thin heat pipe is prone to sag, resulting in damage to the thin heat pipe. In addition, the capillary structure of the heating end of the thin heat pipe is insufficient, which causes the phenomenon of dry out of the heating end of the heat pipe, thereby affecting the performance of the heat pipe. [0004] Therefore, it is necessary to provide a thin heat pipe to solve the above problems. Contents of the invention [0005] In order to solve the deficiencies ...
