Description
一種散熱裝置鰭片結構，尤指一種透過鰭片結構之設計，令散熱流體於鰭片間產生渦流進而提升散熱效能的散熱裝置鰭片結構。 A fin structure of a heat dissipating device, in particular, a fin structure of a heat dissipating device through a fin structure designed to generate a eddy current between the fins and to improve heat dissipation performance.
現行電子設備中之計算單元於計算時皆會產生高熱，故需設置輔助散熱的散熱裝置進行輔助散熱，一般散熱裝置例如為散熱器、均溫板、熱管，又或者透過水冷裝置與該電子設備中之計算單元組設進行解熱之工作，其中散熱器為最普及且最為常被使用的散熱裝置，散熱器主要係透過散熱鰭片增加整體之散熱的面積進而增加散熱效率，而一般散熱器皆會搭配一強制引導氣流的散熱風扇對散熱器進行強制散熱，散熱風扇主要強制引導氣流對散熱器具有鰭片之部位進行散熱，透過氣流對吸附有熱量的鰭片進行強制冷卻，進而達到散熱效果。 In the current electronic equipment, the calculation unit generates high heat during calculation. Therefore, it is necessary to provide a heat dissipation device for auxiliary heat dissipation for auxiliary heat dissipation. The general heat dissipation device is, for example, a radiator, a temperature equalization plate, a heat pipe, or a water-cooling device and the electronic device. The computing unit is set up to perform the anti-heating work. The heat sink is the most popular and most commonly used heat sink. The heat sink mainly increases the heat dissipation area through the heat sink fins, thereby increasing the heat dissipation efficiency. The heat sink fan is forced to dissipate heat with a heat-dissipating fan that forcibly guides the airflow. The heat-dissipating fan mainly forces the airflow to dissipate the heat sink fins through the airflow, and forcibly cools the heat-absorbing fins through the airflow to achieve the heat dissipation effect. .
一般散熱器之鰭片形狀為直列相互平行設置，而鰭片與鰭片之間所形成之空間即為氣流之通道，氣流經過該通道進而冷卻吸附有熱量的鰭片，但鰭片表面往往設置為光滑表面當氣流快速通過時，則無法有效帶走鰭片表面吸附的熱量，若通道過窄則影響氣流通過亦會影響散熱效能。 Generally, the shape of the fins of the heat sink is arranged in parallel with each other, and the space formed between the fins and the fins is a passage of airflow, and the airflow passes through the passage to cool the fins that adsorb heat, but the surface of the fins is often set. For a smooth surface, when the airflow passes quickly, it cannot effectively take away the heat absorbed by the surface of the fin. If the channel is too narrow, the airflow will also affect the heat dissipation performance.
故如何引導散熱流體增加散熱效果則為現行該項業者欲努力改善之首重目標。 Therefore, how to guide the heat dissipation fluid to increase the heat dissipation effect is the first goal of the current industry to improve.
爰此，為解決上述習知技術之缺點，本發明之主要目的，係提供一種可透過鰭片結構體設計令散熱流體產生渦流進而增加散熱效能的散熱裝置鰭片結構。 Therefore, in order to solve the above-mentioned shortcomings of the prior art, the main object of the present invention is to provide a heat sink fin structure that can transmit eddy currents through a fin structure to increase heat dissipation performance.
為達上述之目的，本發明係提供一種散熱裝置鰭片結構，係包含：一本體，由複數薄片體相互堆疊所組成，該等薄片體具有至少一散熱區及至少一吸熱區，該等薄片體之散熱區由複數延伸體所組成，並兩相鄰薄片體之該等延伸體相互交錯疊合設置，並該等延伸體間形成複數通道，所述吸熱區相鄰並連接該散熱區。 In order to achieve the above object, the present invention provides a fin structure for a heat dissipating device, comprising: a body, which is composed of a plurality of sheets stacked on each other, the sheets having at least one heat dissipating area and at least one heat absorbing area, the sheets The heat dissipating area of the body is composed of a plurality of extension bodies, and the extension bodies of the two adjacent sheets are arranged in a staggered manner, and a plurality of channels are formed between the extension bodies, and the heat absorption area is adjacent to and connected to the heat dissipation area.
