Description

Flat Plate Heat Pipes {A Plate Type Heat Pipe}

The present invention relates to a heat pipe that is used to effectively remove or exchange heat generated in electronic products in various industrial fields such as semiconductor component devices, computers, information and communication products, communication satellites, star industry, and heating and heating fields. Particularly, the roof-shaped heat pipe is installed inside the case-shaped enclosure, and the upper space is covered by filling metal powder, magnesium or inorganic material having high thermal conductivity with the remaining empty space after the heat pipe is embedded inside the enclosure. The present invention relates to a planar heat pipe which is capable of maximizing thermal conductivity by a loop-shaped heat pipe evenly distributed inside the enclosure and a metal powder surrounding the heat pipe.

In general, the heat pipe is a vacuum exhaust after injecting a working fluid into a hollow metal pipe and heating one end causes the working fluid to evaporate, move to the other side by the pressure difference, and release heat to the surroundings. After the process of condensation again, it returns to the heating unit to operate continuously.

In addition, in order to efficiently return the liquid working fluid returned after heat dissipation by capillary action as described above, a relatively dense and thin mesh, or a fine groove or sintered metal powder is attached to the inner wall of the metal pipe. Many heat pipes have been used in the form of a straight line in which a working fluid such as water (distilled water), methyl alcohol, acetone, or the like is injected into an attached pipe.

However, when the conventional straight heat pipe is used in a place with a large amount of heat transfer, a plurality of heat pipes have been used by directly attaching to the plate body. However, in order to install such a heat pipe, a plurality of heat pipes may be manufactured and then attached to the plate body. By attaching, the manufacturing process is complicated, of course, there is a disadvantage that the manufacturing cost increases.

In addition, when the heat exchange is performed over a relatively large area as described above, since the straight heat pipes are only bonded to the plate body, many problems such as poor heat distribution efficiency cannot be effectively radiated and heat exchange efficiency is lowered. It was.

SUMMARY OF THE INVENTION The present invention has been made to solve various problems of the related art as described above, and an object thereof is to internally seal a loop-shaped heat pipe with a metal powder having high thermal conductivity and seal it in a cylindrical enclosure. Provides a flat heat pipe that maximizes thermal conductivity by intrinsic metal powder so that heat conduction can be efficiently carried out uniformly over a relatively wide range, and is easy to manufacture, thereby reducing the manufacturing cost of flat heat pipes. have.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exploded perspective view illustrating an assembled state of a flat heat pipe according to the present invention, and FIG. 2 is a partially cutaway perspective view of the flat heat pipe in an assembled state according to FIG. The enclosure 10 is spaced apart from at least one of the fixing protrusions 12 to the lower surface of the interior thereof, and the seating protrusion 14 is protruded inwardly to the upper inner surface of the enclosure 10 having one end opened.

In addition, the inside of the housing 10 is a loop-shaped heat pipe 20 filled with a working fluid (not shown) is seated and fixed between a plurality of fixing projections 12 protruding on the lower surface of the housing, the heat pipe The heat pipe 20 is installed in the housing 10 while the housing 20 is fixed in the housing 10, and the empty space in the remaining housing 10 is filled with a metal powder mixture having excellent thermal conductivity. Member 30 is filled.

Subsequently, the upper opening of the housing 10 in which the heat pipe 20 and the filling member 30 are embedded is sealed by the sealing cover 40.

Therefore, the flat heat pipe of the present invention having the above configuration is assembled as follows.

1 and 2, a plurality of fixing protrusions 12 protruding from the inner bottom surface of the housing 10 having an upper side opened in a cylindrical shape are sequentially bent in a loop shape into spaced apart spaces spaced apart from each other. After the heat pipe 20 filled with the working fluid is seated and fixed, the heat pipe 20 is fixed to the fixing protrusion 12 in the housing 10 and thermal conductivity is maintained in the empty space in the remaining housing 10. Filling member 30, such as an excellent metal powder mixture is filled.

Here, the filling member 30 is filled in the interior of the housing 10 as described above is filled in the interior of the housing 10 having excellent thermal conductivity at room temperature is a metal powder, magnesium powder, ceramic powder, silica Powder, calcite powder, jade powder, talc powder, loess, talc powder are sintered by mixing one or two or more kinds.

Therefore, the filling member 30 filled as described above not only serves as an intermediate medium for effectively dissipating heat dissipated in the heat pipe 20 in the enclosure 10 to the outside of the enclosure 10, and the enclosure 10. Simultaneously serves as a fixing means for firmly fixing the heat pipe 20 in the interior, and also contains a large amount of far infrared rays from mixed inorganic materials, ie, ceramic, silica sand, ganban stone, jade powder, talc powder, loess, snow powder, etc. This radiation has a beneficial effect on the human body.

On the other hand, the assembly is completed by closing the upper opening of the enclosure 10 in the state in which the filling member 30 and the heat pipe 20 are embedded through the cover 40. At this time, the end of the sealing cover 40 is installed by the seating protrusions 14 protruding from the upper inner peripheral surface of the enclosure 10, which can be sealed, and such sealing is to fasten the sealing cover 40 and the enclosure 10 by bolts. , It is preferable to fix the adhesive tightly through welding or the like.

Therefore, the flat heat pipe of the present invention assembled as described above effectively removes heat generated from electronic products in various industrial fields such as semiconductor component devices, computers, information and communication products, communication satellites, starburst industry, and ondol heating field. Used to

Specifically, when heat generated from the product is transferred to one end of the housing 10 of the flat heat pipe of the present invention, such heat is filled through the filling member 30 filled with the inside of the housing 10 and excellent in thermal conductivity. Heat is transferred to one side of the heat pipe 20.

Therefore, when heat is applied to one side of the heat pipe, the working fluid (ammonia, freon, methanol, distilled water, acetone, etc.) filled in the heat pipe 20 absorbs the surrounding heat and heats in a hot gas state. As it moves to the other side of the pipe, the latent heat of evaporation that is moved to the other side of the heat pipe, that is, the portion where the heat radiated from the product does not directly contact, absorbs the surrounding heat as described above, The heat absorbed during the evaporation process is released back to the outside.

Subsequently, the heat released through the other side of the heat pipe as described above is to release the heat to the other end through the filling member.

Therefore, as described above, the flat heat pipe according to the present invention is not only effectively conducting heat transfer to the heat pipe in the enclosure by the filling member filled in the enclosure, but also dissipating or heat the product uniformly over a considerable surface area. Exchange can be made.

On the other hand, the flat plate heat pipe applied to the present invention is not limited to one embodiment of the flat plate heat pipe as described above, by embedding the heat pipe and the filling member continuously bent in a corrugated shape into the cylindrical enclosure, The same effect can be expected.

As described above, according to the planar heat pipe according to the present invention, the roof-shaped heat pipe is internally sealed with a metal powder having high thermal conductivity and sealed inside the cylindrical enclosure, whereby the metal powder impregnated with the heat pipe is provided. By maximizing the thermal conductivity, the heat conduction is made uniformly and efficiently over a wide range, and the production of the product is simple, thereby reducing the manufacturing cost of the flat heat pipe.
