Description of the Invention: [Technical Field] [0001] The present invention relates to a heat dissipating device', and more particularly to a heat dissipating device for an electronic component. [Prior Art 3 [0002] With the increase in the operation speed of the electronic components inside the electronic device and the increase in the power consumption, the corresponding heat is also greatly increased. In order to operate the electronic components at normal operating temperatures, it is usually required. A heat sink is placed on the surface of the electronic component to discharge the heat generated by the electronic component in time. In order to achieve a good heat dissipation effect between the heat sink and the electronic component, various heat sink fastening structures are adopted in the industry. . [0003] The conventional heat sink fastening structure is as shown in FIG. 1. The fastening structure includes two fasteners 10, and a heat sink 20 is fixed to the electronic component 40 disposed on the circuit board 30. A lug 22 extends horizontally outwardly from the two opposite corners of the heat sink 2, and each of the lugs defines a bore 24 for the fastener 1 to penetrate. The fastener 10 has a circular head 12 extending downward from the circular head 12 with a columnar long rod 14 having a smaller diameter than the circular head 12, from the columnar long rod Each of the opposite sides of the bottom portion extends upwardly to form a pair of barbs 16, and a spring 18 is sleeved on the columnar long rod 14 between the head portion 12 and the barbs 16. In use, the fastener 10 is pressed against the through hole 24 of the heat sink 2 to press the fastener 10. The two barbs 16 of the fastener 10 are pressed by the heat sink 2〇 and the circuit board 3〇 toward the columnar long rod 14 and sequentially pass through the through hole 24 of the heat sink 2 and the circuit board 30. The hole 24 corresponds to the hole 32, so that the barb 16 on the fastener 10 protrudes from the circuit board 3 and abuts against the bottom surface of the circuit board 3. The board 3 is clamped by the barbs 16 and the spring 18 is deformed by the bar 098142738.

Since the above structure is resisted to the bottom surface of the circuit board by the barb of the fastener, it is cumbersome and time-consuming to use the external tool to deform the barb of the fastener to be folded out and exit the circuit board and the heat sink, or use a tool. The barb portion is cut off, and the fastener is discarded, which is not conducive to resource reuse, so the fastening structure needs to be further improved.

The width of the extending portion 1161 is equal to the width of the through hole 310. When the extending portion 1161 is received in the through hole 310, the extending portion 1161 can restrict the rotation of the blocking portion 1164 in the horizontal plane in the through hole 310. The end of the stopper portion 164 is slightly cut to form a guiding surface 1165 so that the fastener 110 penetrates into the heat sink 200 and the carrier 300. In some embodiments, the two positioning portions 11 62 are respectively located on opposite sides of the extending portion 1161. The positioning portion 1162 is a protruding post, and the positioning portion 1162 is disposed in a gap with the extending portion 1161. In other embodiments, the blocking portion 11 64 extends only vertically on the top surface of the extension portion 161. The positioning portion 1162 can be other structures, for example, a block. [0013] The heat sink 200 has, in some embodiments, a substantially square base 230 and a plurality of fins 232 extending integrally from the top surface of the base 230. The bottom surface of the susceptor 230 can be used to adhere to the electronic component 400 to absorb heat. A plurality of airflow passages 250 extending in the lateral direction and the longitudinal direction are formed between the heat dissipation fins 232. A space 240 is defined at two opposite corners of the heat sink 200 to serve as a space for the fastener 110 to rotate. A pair of lugs 210 extend horizontally outwardly from opposite corners of the base 230. Each lug 210 is opened at about 981142738 in the middle.
