Heat Sink Structure {HEAT SINK STRUCTURE}

Embodiments of the present invention relate to the structure of a heat sink.

In general, as society develops and people's quality of life improves, people seek more comfortable indoor environments in offices and homes. Therefore, the interest in the interior interior is gradually increasing, showing a great interest in the selection of lighting fixtures that illuminate the dark room as a factor for creating the atmosphere of the interior.

There are many kinds of lighting fixtures, each of which is used differently according to the environment, and in order to create various atmospheres, each lighting fixture must be separately installed according to the purpose.

In general, a lighting device is a device for brightly illuminating an object and a corresponding part of the surrounding area, and largely to create an atmosphere such as a stage, a show window, a restaurant, and information transmission means such as traffic signals, neon signs, and road information signs. And ultraviolet rays, infrared rays, and the like for sterilization, heating, drying, and the like, for fish or insects or for plant cultivation.

Such a lighting device is provided with a heat sink for dissipating heat generated from a heating element (lighting source, etc.) to the outside. By the way, the conventional heat sink has a structure which does not radiate heat directly and rapidly at the junction part with the said heat generating body.

That is, the conventional heat sink has a secondary heat dissipation structure in which the area (heat dissipation area) to be joined to the heat generating element is narrow and induces heat to the side to radiate heat from the outside of the side.

Therefore, there is an urgent need for a heat dissipation structure that can increase the junction area (heat dissipation area) with the heat generator and improve heat dissipation efficiency.

One embodiment of the present invention has a fastening structure that is tightly fixed to the heating element through the nut fastening groove, to provide a heat dissipation structure to improve the heat dissipation efficiency by increasing the adhesive area (heat dissipation area) with the heating element.

One embodiment of the present invention provides a heat sink structure to form a plurality of heat sinks around the body, thereby increasing the heat radiation area to further improve the heat radiation efficiency.

The problem to be solved by the present invention is not limited to the above-mentioned problem, another task (s) not mentioned will be clearly understood by those skilled in the art from the following description.

A heat sink structure according to an embodiment of the present invention has a predetermined area capable of dissipating heat, the body is formed in a disk shape; And a plurality of heat sinks integrally formed with the main body around the main body so as to increase an area capable of dissipating the heat.

The main body may include at least two nut fastening grooves so that the heat generating body and the heat dissipating body which emit the heat by the multi support bolts are tightly fixed.

The main body may include a wire through hole to allow the wire to be inserted therethrough.

The radiating heat may be formed in a sawtooth shape.

The heat sink may be manufactured by an extrusion mold method.

The heat sink may be formed of a heat radiation material including aluminum (Al).

The thickness of the heat sink may be determined according to the surface area or the amount of heat generated by the heat generating element.

The number of the radiating heat may be determined according to the surface area or the calorific value of the heating element that emits heat.

Specific details of other embodiments are included in the detailed description and the accompanying drawings.

1 to 3, the heat sink 100 according to an embodiment of the present invention includes a main body 110 and a plurality of heat sinks 120.

The main body 110 has a predetermined area capable of dissipating heat and is formed in a disc shape.

The main body 110 has two nut fastening grooves 112 so that the heat generating body (see 410 of FIG. 4) and the heat dissipating body 100 are tightly fixed by the multi support bolt (see 430 of FIG. 4). It may be provided. Here, the number of the nut fastening grooves 112 is not limited to two, more than, for example, may be three or four.

Here, a nut is formed on an upper portion of the multi support bolt, and the nut may be fastened to the main body 110 and the heating element.

The main body 110 may include a wire through hole 114 to allow the wire to be inserted therethrough.

When the heat sink 100 is formed in a large size, since the wiring space may not be provided at the side of the heat sink 100 inside the housing of the lighting apparatus, the wire through hole ( 114) can be formed.

However, when the heat sink 100 is formed in a small size, since a wiring space may be provided next to the heat sink 100, the wire through hole 114 may not be formed in the main body 110. It may be.

The heat dissipation blade 120 is integrally formed with the main body 110 around the main body 110 so that an area capable of dissipating the heat is increased. As such, since the heat dissipation area can be increased through the heat dissipation blades 120, the heat dissipation body 100 can radiate heat more efficiently.

The heat radiation blade 120 may be formed in a sawtooth shape. By being formed in the shape of a sawtooth, the heat dissipation 120 may be formed so as to be able to sufficiently dissipate heat around the body 110.

Although the number of the heat radiation blades 120 is illustrated as 60 in the drawing, the number of heat radiation blades 120 is not limited thereto and may be determined by a different number according to the surface area or the amount of heat generated by the heating element.

As such, the heat sink 100 including the main body 110 and the heat sink 120 may be manufactured by an extrusion mold method. Therefore, not only the manufacturing process of the heat sink 100 can be simplified, but also the manufacturing time can be shortened. In addition, the manufacturing cost of the heat sink 100 may be reduced, and the structure of the heat sink 100 may be easily modified.

The heat sink 100 may be formed of a heat radiation material including aluminum (Al). Therefore, it is possible to effectively release the heat generated from the heating element.

Here, the heat dissipating material may be various in addition to the aluminum, and the heat dissipating element 100 may include various types of heat dissipating materials such as copper (Cu), gold (Au), silver (Ag), ceramics, or It may be formed of any one of titanium (Ti) and the like.

The thickness of the heat sink 100 may be appropriately determined according to the surface area or the amount of heat generated by the heat generator.

The heat sink 100 according to the embodiment of the present invention has a structure including the body 110, and a plurality of heat dissipation blades 120 formed integrally around the body 110, the heat radiation area By increasing the heat generated from the heating element can be efficiently discharged, thereby maximizing the heat dissipation efficiency.

As such, in order to discharge heat generated from the heat generator 410 to the outside, the heat sink 100 formed of a heat radiation material such as aluminum is disposed under the heat generator 410.

In this case, the radiator 100 may be tightly fixed to the lower portion of the heating element 410 through the multi support bolt 430, and may radiate heat generated from the heating element 410 to the outside.

In addition, a plurality of heat dissipation blades 120 having a sawtooth shape are formed around the heat dissipation body 100 to increase a heat dissipation area, thereby more effectively dissipating heat generated from the heat dissipating element 410.

In addition, a wire through hole 114 may be formed in the radiator 100 so that the wire drawn out from the circuit board 420 passes.

The circuit board 420 is disposed below the radiator 100 at predetermined intervals. This is to minimize thermal interference between the circuit board 420 and the heat sink 100.
