The invention discloses a plate-shaped heat pipe and a manufacturing method of the plate-shaped heat pipe. The manufacturing method includes the following steps that a plate-shaped metal pipe is provided, and capillary-structured layers are formed on the inner surfaces of the first side wall and the second side wall of the plate-shaped metal pipe respectively; a plate-shaped core rod is inserted and multiple first strip-shaped protrusions and second strip-shaped protrusions are formed on the outer surfaces of the two opposite sides of the plate-shaped core rod at intervals. The first strip-shaped protrusions and the second strip-shaped protrusions are crossed; the plate-shaped metal pipe is extruded and first strip-shaped grooves and second strip-shaped grooves corresponding to the first strip-shaped protrusions and the second strip-shaped protrusions are formed in the surfaces of the capillary-structured layers respectively; the plate-shaped core rod is taken out; the plate-shaped metal pipe is further extruded, so that the protrusions of the capillary-structured layers support one another so as to enhance the anti-pressure strength of the plate-shaped heat pipe, and the grooves serve as steam channels of the plate-shaped heat pipe. By means of the manner, the anti-pressure strength of the plate-shaped heat pipe and the heat dissipation area of the steam channels are improved and the heat dissipation efficiency is improved.
Description
technical field [0001] The invention relates to the field of radiators, in particular to a plate-shaped heat pipe and a manufacturing method thereof. Background technique [0002] With the development of science and technology, electrical appliances such as computers have become a necessity for people to study, work and live. Therefore, heat dissipation devices for dissipating heat from various electronic components have emerged at the historic moment, and plate-shaped heat pipes have gradually become common heat dissipation devices. The existing manufacturing method of the plate-shaped heat pipe is as follows: a. providing a metal pipe, b. inserting a mandrel, c. injecting metal particles and sintering, and pressing to form a plate-shaped heat pipe. The plate-shaped heat pipe manufactured by this method utilizes the smooth inner surface area of the sintered metal particles for heat dissipation, and the heat dissipation area is small, so the heat dissipation effect is not...
