Description
FIELD OF THE INVENTION
[0001] The present invention relates to a plate-type heat pipe
sealing structure and a manufacturing method thereof. The
plate-type heat pipe includes a main body and a tube body. The main
body of the plate-type heat pipe is formed with a notch in which
the tube body is positioned without protruding from the main body
of the plate-type heat pipe. Accordingly, when assembled with a
heat sink unit, the tube body of the plate-type heat pipe will not
interfere with the heat sink unit. In this case, the plate-type
heat pipe can be more conveniently assembled with the heat sink
unit.
BACKGROUND OF THE INVENTION
[0002] The plate-type heat pipe has the advantages of high heat
conductivity, lightweight, simple structure, multiuse and easy
processing. Moreover, the plate-type heat pipe is able to transfer
heat at high efficiency without consuming any power. Therefore, the
plate-type heat pipe is widely applied in various fields,
especially applied to a heat-generating electronic component for
quickly conducting the heat from the electronic component and
avoiding heat accumulation.
[0003] A conventional plate-type heat pipe works on the principle
that the plate-type heat pipe has an internal vacuumed chamber in
which a working fluid is filled.
[0004] When heated, the working fluid phase-changes into vapor to
transfer heat. After cooled, the working fluid phase-changes into
liquid phase and flows back to complete a cycle. An evaporation
face of the plate-type heat pipe is attached to the surface of the
heat-generating electronic component to partially absorb and
dissipate the heat generated by the electronic component.
[0005] There is a trend to manufacture slimmer and slimmer
electronic devices for easy carriage. To keep up with the trend,
the plate-type heat pipe applied to the electronic component for
dissipating the heat has become thinner and lighter. The
conventional plate-type heat pipe has a closed end connected with a
tube body. The closed end and the tube body protrude from a
rectangular area of the main body of the plate-type heat pipe.
Therefore, when assembling the plate-type heat pipe with a heat
sink unit, the closed end and the tube body will interfere with the
heat sink unit. This often leads to inconvenience in the assembling
process or even breakage of the plate-type heat pipe. Therefore,
the conventional plate-type heat pipe has the following
shortcomings:
[0006] 1. It is inconvenient to assemble the conventional
plate-type heat pipe with the heat sink unit; and
[0007] 2. When assembling the conventional plate-type heat pipe
with the heat sink unit, the closed end and the tube body are
likely to interfere with the heat sink unit.
SUMMARY OF THE INVENTION
[0008] A primary object of the present invention is to provide a
plate-type heat pipe sealing structure capable of avoiding
interference of the plate-type heat pipe with the heat sink unit in
the assembling process.
[0009] A further object of the present invention is to provide a
manufacturing method for a plate-type heat pipe sealing structure,
which is capable of avoiding interference of the plate-type heat
pipe with the heat sink unit in the assembling process.
[0010] To achieve the above and other objects, the plate-type heat
pipe of the present invention includes a main body and a tube body.
The main body has a first side, a second side, a third side, a
fourth side and a notch. The first side intersects the third and
fourth sides to define a first intersection section and a second
intersection section. The second side intersects the third and
fourth sides to define a third intersection section and a fourth
intersection section. The notch is selectively disposed on one of
the first and second sides or one of the first, second, third and
fourth intersection sections. The main body has an internal
chamber. The tube body has a first end, which is a closed end, and
a second end inserted in the notch and connected with the main body
in communication with the chamber.
[0011] Still to achieve the above and other objects, the
manufacturing method for the plate-type heat pipe sealing structure
of the present invention includes steps of: providing a plate-type
heat pipe having a main body; cutting the main body of the
plate-type heat pipe to form a notch; and inserting a tube body
into the notch and connecting the tube body with the main body and
sealing the notch.
[0012] According to the plate-type heat pipe sealing structure of
the present invention, the closed end of the main body and the tube
body will not protrude from the rectangular area of the main body
of the plate-type heat pipe. Therefore, when assembling the
plate-type heat pipe with a heat sink unit, the closed end of the
main body and the tube body will not interfere with the heat sink
unit. This facilitates the assembling process of the plate-type
heat pipe.
[0013] Accordingly, the present invention has the following
advantages:
[0014] 1. When assembling the plate-type heat pipe of the present
invention with the heat sink unit, the closed end of the main body
and the tube body will not interfere with the heat sink unit;
and
[0015] 2. It is convenient to assemble the plate-type heat pipe of
the present invention with the heat sink unit.
