BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a heat dissipating device for integrally forming a steam chamber and a radiating fin in a housing by a 3D printer, and more particularly to a heat radiating device for radiating heat from a steam chamber array And a heat dissipation array formed integrally with a 3D printer.

Devices such as heat sinks are used to remove heat from components or from the system to the surroundings.

Such a heat dissipating device is determined to have a low value of thermal resistance for high performance.

Generally, this thermal resistance is caused by heat dissipation resistance between the surface of the heat dissipating device and the surrounding environment. In order to minimize the heat dissipation resistance, highly conductive materials such as copper and aluminum are generally used to make a heat dissipating device.

In general, however, such a solids diffusion mechanism is not sufficient to meet the higher cooling demands for newer electronic equipment.

Thus, more efficient mechanisms have been developed and evaluated, and vapor chambers have been one of the usual mechanisms to be considered.

The vapor chambers utilize the principle of a heat pipe in which heat is transferred by vaporized working liquid and is diverted by the vapor flow. Where the vapor is eventually condensed onto the cooling surface, so that the heat is transferred from the evaporating surface (the interface with the heat source) to the condensing surface (cooling surface).

If the cooling surface portion is much higher than the evaporation surface, the heat dissipation can be made efficient because a phase change (liquid-vapor-liquid) mode takes place near the isothermal environment.

These steam chambers serve as a cooler that dissipates heat when various heat sources are in contact with each other. In a device in which a large heat generating device or major electronic components are arranged in a cluster, it is common to combine the housings for a protective function.

In order to remove heat generated by electronic components, it is common to install a heat dissipation device such as a vapor chamber in an electronic product. However, heat dissipation is induced by coupling a heat dissipation device including a heat pipe to a plurality of electronic products inside the housing In order to achieve this, it is not easy to install the heat dissipation device individually, and the time required for the operation is long, so the productivity is reduced. Since the heat dissipation device is already made compact by the design, The thermal resistance of the contact portion is generated and the heat dissipation performance is remarkably lowered.

Therefore, a method for solving such problems is required.

SUMMARY OF THE INVENTION The present invention has been conceived to solve the above problems of the prior art, and it is an object of the present invention to provide a heat dissipating device that is integrally formed in a housing that protects electronic components, The present invention provides a heat dissipating device that is made of a 3D printer in which a vapor chamber array and a heat dissipation array are integrally formed so as to maximize heat dissipation performance without generating heat resistance.

The problems of the present invention are not limited to the above-mentioned problems, and other problems not mentioned can be clearly understood by those skilled in the art from the following description.

A first part formed of a 3D printer and partially in contact with a heat source and a second structure formed of a first part and a second part facing each other with a space between the first space and the cooling space, And a heat radiating part protruding from the part toward the cooling space and protruding at a plurality of uniform intervals so as to cool the heat transferred from the first part through air provided in the cooling space, And may be integrally formed with the body.

A steam chamber part integrally formed on one surface of the body and having a condensable fluid accommodated therein to dissipate heat in the accommodation space; And a heat radiating part formed between the chamber parts and serving as a passage communicating with the outside to cool the vapor chamber part, wherein the vapor chamber part and the radiating part may be integrally formed in the body.

And a first part adjacent to the accommodation space to be in contact with the heat source,

And a second part formed to surround the heat radiating part.

The steam chamber part may be integrally formed with the first part.

The steam chamber part may be formed such that a pair of the steam chamber parts are opposed to each other in the body.

The steam chamber part and the heat radiating part are integrally formed so that the condensable fluid therein can flow inside the vapor chamber part and the heat radiating part.

At least one surface of the vapor chamber part may be formed in a wick structure.

The heat radiating part may protrude from the steam chamber part at equal intervals in the vertical direction toward the second part.

And, the vapor chamber part may be formed such that an injection port for injecting a part of the condensable fluid corresponds to the number of the vapor chamber parts.

The vapor chamber part may also include a separate cap that closes the injection port.

At least one or more of the blowing fan parts may be detachably attached to the body, and external air may be injected between the heat radiating part and the second part.

First, the vapor chamber and the radiating fin are integrally formed in the housing, thereby suppressing the occurrence of thermal resistance between the components, thereby maximizing the heat radiation performance.

Second, the radiating fins are integrally formed in the steam chamber, so that cooling of the radiating fins due to the movement of the condensable fluid therein is performed quickly.

FIG. 3 is a 3D printer in which a vapor chamber array and a heat dissipation array according to the first embodiment of the present invention are integrally formed. FIG. 4 is an enlarged view of the vapor chamber part 200 and the heat radiating part 300 in the heat radiating device according to the first embodiment of the present invention. And the blowing fan part is coupled to the body 100 in the heat dissipating device.

1, a heat dissipating device manufactured by a 3D printer in which a vapor chamber array and a heat radiation array according to the present invention are integrally formed includes a body 100, a steam chamber part 200 formed on both sides of the body 100, And a heat radiating part 300 formed between the body 100 and the steam chamber part 200.

The body 100 has a receiving space formed therein and at least a part thereof is in contact with a heat source. The steam chamber part 200 is integrally formed on one surface of the body 100, An injection tube capable of injecting a condensable fluid is formed to radiate heat inside the accommodation space due to the phase change of the condensable fluid. The heat radiating part 300 is integrally formed with the steam chamber part 200 in a protruded form between the body 100 and the steam chamber part 200 to cool the heat generated in the steam chamber part 200 .

The ventilation fan part 400 is detachably coupled to a part of the body 100 to provide a wind to discharge the heat inside the accommodation space to the outside, and the steam chamber part 200 and the heat radiating part 300 And is integrally formed on the body 100.

Specifically, the body 100 has the receiving space formed therein, the receiving space communicating with the outside in the front-rear direction, and both sides and the upper and lower surfaces having the closed shape.

The heat source may be disposed in the accommodation space, and more specifically, the body 100 may surround the heat source.

The heat source may be partially in contact with the body 100.

Thus, the heat generated in the heat source is cooled by the steam chamber part 200 and the heat radiating part 300 formed in the body 100.

The body 100 has the vapor chamber part 200 and the heat radiating part 300 formed on both sides thereof. The body 100 has a double structure.

As shown in FIG. 1, the steam chamber part 200 and the heat radiating part 300 are integrally formed on both sides of the body 100.

Specifically, the body 100 is formed of a dual structure of a first part 120 and a second part 140. The first part 120 is adjacent to the receiving space, Is adjacent to the outside.

In the second part 140, the vapor chamber part 200 is formed and the condensable fluid is received therein.

The condensable fluid flows inside the vapor chamber part 200 while making a phase change by the heat generated from the smoke source.

The details will be described later.

Next, a heat dissipating device manufactured by a 3D printer in which a vapor chamber array and a heat radiation array are integrally formed will be described in detail with reference to FIG.

As shown in FIG. 2, the steam chamber part 200 and the heat radiating part 300 are formed on both sides of the body 100.

Since the steam chamber part 200 and the heat radiating part 300 are integrally formed in the present invention, the steam chamber part 200 and the heat radiating part 300 are integrally formed, You can.

Specifically, the steam chamber part 200 and the heat radiating part 300 are formed inside the first part 120, and a condensable fluid is received therein although not shown.

The first part 120, the steam chamber part 200, and the heat radiating part 300 are separated from each other.

That is, the first part 120 and the vapor chamber part 200 are not communicated with each other, so that the condensable fluid of the vapor chamber part 200 does not flow into the first part 120, (300). ≪ / RTI >

The outer surface of the first part 120 is protruded toward the second part 140 and the heat radiating part 300 is formed.

The heat radiating part 300 has a shape protruding at a predetermined interval in the vertical direction and the heat radiating part 300 has the purpose of radiating heat generated in the vapor chamber part 200 to the outside.

This is because a cooling space is formed between the first part 120 and the second part 140 so that the outside air moves and cools the heat radiating part 300 to cool it.

At this time, since the heat radiating part 300 has a shape protruding from the steam chamber part 200 toward the second part 140, the area of contact with the air is large and cooling is effective.

The heat radiating part 300 is elongated in the transverse direction on the outer surface of the steam chamber part 200.

The reason for this is that the wind provided in the blowing fan part coupled to a part of the body 100 cools the heat radiating part 300 while passing through the cooling space.

On the other hand, an injection pipe 240 for injecting a condensable fluid into the steam chamber part 200 is formed in a part of the upper surface of the body 100. When the condensing fluid is not injected into the injection tube 240 by a separate stopper (not shown), the injection tube 240 is closed.

This will be described in more detail in FIG.

3 is an enlarged view of a cross section of the steam chamber part 200 and the heat radiating part 300 in FIG.

As shown in the figure, the steam chamber part 200 has a wick structure 220 formed on its outer surface and is not in communication with the first part 120.

The reason why the surface of the steam chamber part 200 contacting the first part 120 is formed of the wick structure 220 is that the wick structure 220 can remarkably cool the wick structure 220 .

The wick structure 220 has a shape in which protrusions are repeatedly protruded from the side surface, and as the size of the protrusion is smaller, the capillary force is increased and contact with the first part 120 is facilitated.

Accordingly, a large amount of the condensable fluid can be rapidly moved by the large capillary force through the size of the protrusion of the wick structure 220, and the heat of the accommodation space can be absorbed.

In addition, one side of the steam chamber part 200 in the direction of the cooling space is formed with the wick structure 220 together with the heat dissipation part 300, thereby maximizing the cooling effect.

This is because the condensable fluid inside is moved to the heat radiating part 300 so that the cooling is rapidly performed and the heat inside the accommodating space is absorbed again, so that the heat radiation according to the phase change can be accelerated quickly.

The condensable fluid is vaporized by heat absorbed by the surface adjacent to the accommodation space, and the condensed fluid, which is vaporized again, is cooled in the heat dissipation part 300 to be liquefied, And the heat is discharged from the cooling space to the outside.

Since the steam chamber part 200 and the heat radiating part 300 according to the present invention are integrally formed with the first part 120, heat radiation inside the receiving space can be more effectively promoted.

This is because the condensable fluid

To this end, the blowing fan part is coupled with the body 100 at one side along the direction in which the heat radiating part 300 is formed to provide wind from the outside to the cooling space and the accommodating space.

Here, the blowing fan part is detachably coupled to the body 100, so that the blowing fan part is not limited to one blowing fan as shown in the figure, but may be the blowing fan part formed with a plurality of blowing fans have.

In the second embodiment, the body 100 may have a shape in which the steam chamber part 200 is integrally formed. In the third embodiment, only the heat radiating part 300 is formed in the body 100 Lt; / RTI >

In addition, depending on the characteristics of the vapor chamber part 200, the vapor chamber part 200 may be formed of any one of metal fiber, metal sintered body, and activated carbon fiber.

It will be apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit or scope of the invention as defined in the appended claims. It is obvious to them. Therefore, the above-described embodiments are to be considered as illustrative rather than restrictive, and the present invention is not limited to the above description, but may be modified within the scope of the appended claims and equivalents thereof.
