Description of the invention: '[Technical field to which the invention pertains] The present invention relates to a heat sink, and more particularly to a pole heat sink. [Prior Art] Light Emitting Diodes (Lights) are widely used because of their energy saving and environmental protection. However, the two-party and South Power LEDs emit heat in a timely manner. Light-emitting diode lamps will have a significant decrease in luminous efficiency due to high temperature, and even cause bad. At present, it is common practice in the industry to place a heat sink under the LED to dissipate heat, such as the US No. 6,517,218 B2. That is, a light-emitting diode device includes a substrate and heat fins extending from the substrate, and the heat absorbed by the substrate from the light-emitting diode is transmitted to the ® film to radiate heat to the periphery by the heat-dissipating fins. In order to improve the heat dissipation efficiency of the south, it is generally necessary to increase the heat dissipation or increase the size of the heat sink fins, but this makes the hair radiator and the entire lighting device too large and oversized. It is necessary to provide a light-emitting diode heat sink with a limited heat dissipation effect. A heat sink includes a heat sink, and the heat sink is counted from above. Under the stacking of heat-dissipating fins, these heat-dissipating two-I LEDs are applied, and if the parts of the loss-reducing parts are damaged, the US body heats up most of the heat-dissipating heat. The strips are spaced apart from each other along the direction of 7 200925504, and the edges of each of the fins are opened with a number of openings, and the openings are formed to form a plurality of airflow passages up and down. • The airflow passages penetrate the fins from top to bottom. The heat sink is vertically placed above the light emitting diode mold, and a part of the heat generated by the light emitting diode module radiates the air in the bottom of the heat sink and causes the air to rapidly heat up, and the air can smoothly flow upward through the air flow passage. The side emits and heats, and at the same time, the hot air passing through the air passage can also contact the side wall of the heat dissipation fin surrounding the channel more deeply, and the heat of the heat fin can be quickly taken away, thereby further improving the heat dissipation efficiency of the heat sink. . [Embodiment] Referring to FIG. 1 and FIG. 2, a heat device 100 for dissipating heat as a light-emitting diode module (not shown) is provided. The heat sink 100 includes a heat sink 10, a tube 30 inserted through the heat sink 10, and a bottom heat conducting plate 40 disposed on the heat sink 10 and the heat pipe 30. The heat sink 10 includes a plurality of fin-shaped fins. The fins 12 are stacked from top to bottom to form a cylinder. The circumferential edges of each of the fins 12 form a plurality of mutually rectangular openings 120. Arranged in the circumferential direction, the openings 120 of the heat dissipating fins 12 correspond to each other from above, so that the circumferential periphery of the heat sink 10 forms a complex complex, and the group of shots to the hollow-*-speed airflow will be interspersed. The scatter of a device of the VS, the square 12, the body, the uniform lower phase number of the upper airflow channel 122 under the connection of 200925504. Each heat dissipation, the fin ΐ 2 is provided with a two-way formed by stamping The hole 124 and the periphery of the through hole 124 are extended upwards. The flanges 125 are extended, and the adjacent heat dissipation fins 12 are spaced apart from each other by the flange a. ·Continuous-诵a. „ ^ 』 The through holes (2) of the heat dissipation fins 12 respectively correspond to each other to form two circular passages for the heat pipes 3 to pass through from top to bottom. The diffuser 〇 is not limited to the combination of the heat sink fins 12, and may be other types of heat sinks, such as the heat sink shown in FIG. 3, such that the heat sink includes a central heat conduction && And a plurality of heat radiating fins 12a extending horizontally from the surface of the heat conducting column to the surrounding body. The heat pipe 3 is shaped to include an intermediate heat absorbing section 32 and two heat releasing sections 35 from the end of the heat absorbing section 32. The heat absorbing section 32 is also said to be privately-supplied. The heat-dissipating section I and the 35-shell are connected to each of the 124s, thereby circumventing the fuses of the 'following' and the 12-hole through-hole device. The heat conducting plate 40 is made of high thermal conductivity copper or aluminum, and the top of the heat conducting plate 40 is woven into a groove 42 for receiving the heat pipe 3, the surface or the groove of the concave 30. 42. Through hole U4 ", 攸 32. The heat pipe 30 and the heat conducting plate 40 may be coated with a heat conductive adhesive in the heat pipe, and the heat radiating fins 12 may be welded to each other. When assembling, the fins can be first fixed: = in the body. On the exothermic section 35 of 30, the T is then soldered to the heat pipe & 32 in the recess 42 of the heat conducting plate 9 200925504. The heat sink 100 is then placed vertically in the light emitting diode module. Above and make the bottom of the heat conducting plate 40.卩 and LED module are attached. During operation, the illuminating pole body is molded and generates a large amount of heat, and a part of the heat is heat-received to receive VZ ** I L. — and is transferred to the heat sink 10 by the heat pipe 30 and progressively radiates 'other part of heat' Radiating into the air of the radiator and causing the air to heat up rapidly, the hot air is scattered from the bottom of the bamboo shoot. The bottom of the radiator 10 is along the edge of the radiator 10, and the second gas passes through the airflow passage i 22 The π-speed heat dissipation can be performed more smoothly upwards as indicated by the arrow 7〇, and at the same time, the hot air passing through the 1埶=channel 122 can also have more sidewalls of the 2% sheet 12 surrounding the airflow passage 122. Deeper contact, on the one hand, can transfer the heat of the film 12 quickly, on the other hand, the heat can be taken from the upper part of the heat sink 10 to the upper half of the heat sink 10, making full use of the upper part of the ❹, Zheng 2 • turn 12 Heat dissipation to further improve heat dissipation efficiency. The opening 120 in the first embodiment described above is not limited to a rectangular shape, and may be in the form of a ?? The heat dissipation device 200 shown in FIG. 4 and FIG. 5 and the opening 220 of the heat dissipation fin of the political heating device 200 have a round mouth shape, and the opening 32 of the heat management device 300 is trapezoidal, and these openings are 220 and 32 〇. Compared with the opening 12〇, the airflow passages 222 and 322 formed by the openings 3, 3 20 have a larger passage area than the air passage 122 in the first embodiment, and can accommodate the hot air of the passage and the eve. The contact area between the hot air and the fins around the air passages 222, 322 also increases, so that the heat sink having the arcuate opening 220 and the trapezoidal opening 320 of 200925504 • 200, 300 has more heat sink 100 than the heat sink 100 High heat dissipation efficiency. It is worth noting that if the openings 220, 320 are opened too much, the area of the fins 12 will be reduced correspondingly, which will have a certain adverse effect on the heat dissipation efficiency. The heat dissipation fins 12 in the first embodiment are not limited to a circular shape, and may be square or other shapes. In summary, the present invention complies with the requirements of the invention patent, and submits a patent application according to the law. However, the above description is only the preferred embodiment of the present invention, and equivalent modifications or variations made by those skilled in the art of the present invention should be included in the scope of the following claims.
