201141366 六、發明說明： 【發明所屬之技術領域】 本發明係關於一種散熱系統，特別是一種用於電腦機 殼内可以調整位置之散熱系統。 【先前技術】 在現今的電腦系統中，須特別重視機體散熱的問題， 以避免電腦系統之溫度過高而導致電腦系統損壞。尤其是 對於最易產生高溫的中央處理器或是記憶體而言。以作為 伺服器之電腦系統(例如ιυ伺服器）為例，由於需要長時間 開機以持續地執行電腦系統，因此更需要較佳的散熱系統 以避免電腦系統之溫度過高。 因此在先前技術中，已經揭露一種適用於伺服器之電 腦系統之散熱系統。接著請參考圖1係先前技術之散熱系 統之架構圖。先前技術之電腦機殼90係用於一伺服器之電 腦系統，其内部設置有散熱系統91、導風罩92及電腦系 統之元件93。散熱系統91係固定於電腦機殼90上。散熱 系統91包括複數之風扇容置槽911及複數之風扇912。其 中散熱系統91之複數之風扇912係直接對著電腦系統之元 件93以提供風流，並藉由導風罩92以集中空氣的流動。 但由於不同之電腦系統有不同之規格設計，因此風扇 912所擺設的位置可能無法將電腦系統之元件93之範圍全 部包括進去。就如同圖1所示，若散熱系統91僅具有四個 201141366 風扇912，則此四個風扇912所導出之風流無法覆蓋電腦 系統之元件93之全部範圍。必須要有五個風扇912才能將 風流完全覆蓋住電腦系統之元件93之全部範圍，因為會需 要多出一個風扇912之成本。並且導風罩92為了配合風扇 912之數量及集中風流’導風罩92需要經過特殊設計才能 有較佳的傳導效果。由此可知，先前技術之散熱系統91會 增加製造上的成本。 因此有必要發明一種新的散熱系統以解決先前技術之 缺失。 【發明内容】 本發明之主要目的係在提供一種散熱系統，用於電腦 機殼内可以具有調整位置之功能，以達到較佳的散熱效果。 為達成上述之目的，本發明之散熱系統係設置於電腦 機设内。散熱系統包括至少一風扇、複數之風扇容置槽、 滑軌及固定件。複數之風扇容置槽用以放置該風扇。滑執 係與複數之風扇容置槽互相合，使得複數之風扇容置槽 得以於滑轨上滑動。固定件用以於複數之風扇容置槽滑動 至-定點時’固定複數之風扇容置槽，以使得風扇得以於 電腦機殼内提供一風流以達到散熱效果。 【實施方式】 為讓本發明之上述和其他目的、特徵和優點能更明顯 易懂’下文特舉出本發明之具體實施例，並配合所附圖式， 201141366 作詳細說明如下。 以下請一併參考圖2〜3關於散熱系統之相關示意圖， 其中圖2係本發明之散熱系統固定於第一定點之實施方式 之示意圖，圖3係本發明之散熱系統固定於第二定點之實 施方式之示意圖。 本發明之散熱系統10係設置於一電腦機殼1内，用以 對設置於電腦機殼1内之電腦系統之元件61(如圖4所示） 提供較佳的散熱環境。散熱系統10特別是用於需不間斷工 作之電腦系統，例如用於伺服器之電腦系統，例如1U伺 服器，但本發明之散熱系統10並不限使用於此。 散熱系統10包括複數之風扇容置槽11、風扇12、滑 軌20及固定複數之風扇容置槽11之固定件31。在本發明 之一實施例中，複數之風扇容置槽11係固接在一起，而可 同時滑動，但本發明並不以此為限。複數之風扇容置槽11 亦可個別調整位置。複數之風扇容置槽11用以放置至少一 風扇12，其中風扇容置槽11之數量係多於或等於風扇12 之數量，亦即本發明並不限定風扇12須放滿全部之風扇容 置槽11，可以視需求調整風扇12之數量及放置之位置。 風扇12之出風口係直接對著電腦系統之元件61，以對電 腦系統之元件61提供風流以達到散熱效果。 複數之風扇容置槽11係與滑軌20互相配合，使得複 數之風扇容置槽11可在滑執20上滑動。在本發明之一實 施方式中，風扇容置槽11僅在滑軌20上之第一定點21及 第二定點22之間滑動，但本發明並不以此為限。本發明亦 可設定風扇容置槽11能在滑軌20上之任意定點間滑動。 201141366 其中第一定點21及第二定點22之距離係為半個風扇12之 寬度。在本實施例中，固定件31係為一螺拴，但本發明並 不限於此。固定件31用以將複數之風扇容置槽n鎖固於 第一定點21或第二定點22,但本發明並不以固定於第一 疋點21或第二定點22此為限。藉由上述的結構，即可將 複數之風扇12之出風口調整至正對著電腦系統之元件61。 另一方面’由於當複數之風扇容置槽U於第一定點21 及第二定點22之間滑動時，複數之風扇容置槽丨丨與電腦 • 機殼1之側邊必定會產生空隙，此空隙會導致風流迴流而 降低散熱系統10之散熱效率。因此風扇容置槽n與電腦 機设1之侧邊之間還具有對流擋件41，用以阻擋風流迴 流。在圖2中，當風扇容置槽U固定於第一定點Μ時， 風扇容置槽11之左侧與電腦機殼1之側邊之間係設置對流 擋件41 ’以阻擋風流迴流。同樣地，在圖3中當風扇容置 槽11固定於第二定點22時’風扇容置槽11之右側係設置 對流擋件41，以阻擋風流迴流。 9 最後請參考圖4係本發明之散熱系統與電腦系統之元 件配合之實施方式之架構圖。 根據上述的結構描述，本發明之風扇容置槽11可以根 據電腦系統之元件61位置，將複數之風扇12全部對著電 腦系統之元件61。電腦系統之元件61係為中央處理器或 疋記憶卡等元件’但本發明並不以此為限。並且在本發明 之較佳實施例中，散熱系統！〇可以搭配導風罩51。導風 罩51係與複數之風扇容置槽^互相配合’直接設置於風 扇12之出風口，讓風扇12產生之風流能全部流經電腦系 201141366 統之元件61，以達到最佳的散熱效果。 由上述的說明可知，本發明之散熱系統10可以節省風 扇12之數量，同時導風罩51之形狀亦不需經過特殊設計， 可以節省下許多製造上的成本。 綜上所陳，本發明無論就目的、手段及功效，在在均 顯示其迥異於習知技術之特徵，懇請貴審查委員明察， 早曰賜准專利，俾嘉惠社會，實感德便。惟應注意的是， 上述諸多實施例僅係為了便於說明而舉例而已，本發明所 主張之權利範圍自應以申請專利範圍所述為準，而非僅限 於上述實施例。 【圖式簡單說明】 圖1係先前技術之散熱系統之架構圖。 圖2係本發明之散熱系統固定於第一定點之實施方式之示 意圖。 圖3係本發明之散熱系統固定於第二定點之實施方式之示 意圖。 圖4係本發明之散熱系統與電腦系統之元件配合之實施方 式之架構圖。 【主要元件符號說明】 先前技術： 電腦機殼90 散熱系統91 201141366 複數之風扇容置槽911 複數之風扇912 導風罩92 電腦系統之元件93 本發明： 電腦機殼1 散熱系統10 •風扇容置槽11 風扇12 滑軌20 第一定點21 第二定點22 固定件31 對流擋件41 φ 導風罩51 電腦系統之元件61201141366 VI. Description of the Invention: [Technical Field] The present invention relates to a heat dissipation system, and more particularly to a heat dissipation system for adjusting a position in a computer casing. [Prior Art] In today's computer systems, special attention must be paid to the problem of heat dissipation in the body to avoid damage to the computer system caused by excessive temperature of the computer system. Especially for CPUs or memories that are most prone to high temperatures. For example, a computer system (such as an υ server) that is a server requires a better cooling system because it requires a long time to continuously execute the computer system to avoid excessive temperature of the computer system. Therefore, in the prior art, a heat dissipation system for a computer system suitable for a server has been disclosed. Next, please refer to FIG. 1 , which is a structural diagram of a prior art heat dissipation system. The computer casing 90 of the prior art is used in a computer system of a server, and is internally provided with a heat dissipation system 91, an air hood 92, and a component 93 of the computer system. The heat dissipation system 91 is fixed to the computer casing 90. The heat dissipation system 91 includes a plurality of fan receiving slots 911 and a plurality of fans 912. The plurality of fans 912 of the heat dissipation system 91 are directly opposite the components 93 of the computer system to provide airflow, and the air hood 92 is used to concentrate the flow of air. However, since different computer systems have different specifications, the location of the fan 912 may not be able to include all of the components of the computer system 93. As shown in Fig. 1, if the heat dissipation system 91 has only four 201141366 fans 912, the airflow derived by the four fans 912 cannot cover the entire range of the components 93 of the computer system. There must be five fans 912 to completely cover the full range of components 93 of the computer system, as an additional fan 912 would be required. Moreover, in order to match the number of fans 912 and to concentrate the airflow hood, the air hood 92 needs to be specially designed to have a better conduction effect. It can be seen that the prior art heat dissipation system 91 increases the manufacturing cost. It is therefore necessary to invent a new heat dissipation system to address the lack of prior art. SUMMARY OF THE INVENTION The main object of the present invention is to provide a heat dissipation system for the function of adjusting a position in a computer casing to achieve a better heat dissipation effect. In order to achieve the above object, the heat dissipation system of the present invention is disposed in a computer device. The heat dissipation system includes at least one fan, a plurality of fan receiving slots, a slide rail and a fixing member. A plurality of fan accommodating slots are used to place the fan. The slipper is engaged with the plurality of fan receiving slots, so that the plurality of fan receiving slots can slide on the sliding rails. The fixing member is used for sliding the plurality of fan receiving slots to the fixed point to fix a plurality of fan receiving slots, so that the fan can provide a wind flow in the computer casing for heat dissipation. The above and other objects, features and advantages of the present invention will become more <RTIgt; <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; Please refer to FIG. 2 to FIG. 3 for a schematic diagram of a heat dissipation system, wherein FIG. 2 is a schematic diagram of an embodiment of the heat dissipation system of the present invention fixed to a first fixed point, and FIG. 3 is a heat dissipation system of the present invention fixed to a second fixed point. Schematic diagram of an embodiment. The heat dissipation system 10 of the present invention is disposed in a computer casing 1 for providing a better heat dissipation environment for the components 61 (shown in FIG. 4) of the computer system disposed in the computer casing 1. The heat dissipation system 10 is particularly useful for computer systems that require uninterrupted operation, such as computer systems for servers, such as 1U servos, but the heat dissipation system 10 of the present invention is not limited thereto. The heat dissipation system 10 includes a plurality of fan receiving slots 11, a fan 12, a slide rail 20, and a fixing member 31 for fixing a plurality of fan receiving slots 11. In one embodiment of the present invention, the plurality of fan receiving slots 11 are fixed together and can slide simultaneously, but the invention is not limited thereto. The plurality of fan receiving slots 11 can also be individually adjusted in position. The fan receiving slot 11 is configured to receive at least one fan 12, wherein the number of the fan receiving slots 11 is greater than or equal to the number of the fans 12, that is, the present invention does not limit the fan 12 to be fully filled with the fan. The slot 11 can adjust the number and placement of the fan 12 as needed. The air outlet of the fan 12 is directly facing the component 61 of the computer system to provide air flow to the component 61 of the computer system for heat dissipation. The plurality of fan receiving slots 11 cooperate with the slide rails 20 such that the plurality of fan receiving slots 11 are slidable on the slide 20. In one embodiment of the present invention, the fan receiving groove 11 slides only between the first fixed point 21 and the second fixed point 22 on the slide rail 20, but the invention is not limited thereto. The present invention can also be configured to allow the fan receiving slot 11 to slide between any fixed points on the slide rail 20. 201141366 The distance between the first fixed point 21 and the second fixed point 22 is the width of the half fan 12. In the present embodiment, the fixing member 31 is a thread, but the present invention is not limited thereto. The fixing member 31 is used to lock the plurality of fan receiving slots n to the first point 21 or the second point 22, but the invention is not limited to the first point 21 or the second point 22. With the above structure, the air outlets of the plurality of fans 12 can be adjusted to face the component 61 of the computer system. On the other hand, when the plurality of fan receiving slots U slide between the first fixed point 21 and the second fixed point 22, the plurality of fan receiving slots and the side of the computer casing 1 must have a gap. This gap causes the airflow to flow back and reduces the heat dissipation efficiency of the heat dissipation system 10. Therefore, between the fan receiving slot n and the side of the computer device 1, there is also an convection member 41 for blocking the return of the wind. In FIG. 2, when the fan receiving groove U is fixed to the first fixed point ,, the flow restricting member 41' is disposed between the left side of the fan receiving groove 11 and the side of the computer casing 1 to block the flow of the air. Similarly, in Fig. 3, when the fan accommodating groove 11 is fixed to the second fixed point 22, the right side of the fan accommodating groove 11 is provided with a flow restricting member 41 to block the flow of the air. 9 Finally, please refer to FIG. 4, which is an architectural diagram of an embodiment of the heat dissipation system of the present invention and a component of a computer system. According to the above structural description, the fan accommodating groove 11 of the present invention can face all of the plurality of fans 12 against the components 61 of the computer system in accordance with the position of the component 61 of the computer system. The component 61 of the computer system is a component such as a central processing unit or a memory card, but the invention is not limited thereto. And in a preferred embodiment of the invention, the heat dissipation system! 〇 can be matched with the air hood 51. The air hood 51 is matched with a plurality of fan accommodating slots ^ directly disposed at the air outlet of the fan 12, so that the wind flow generated by the fan 12 can all flow through the component 61 of the computer system 201141366 to achieve the best heat dissipation effect. . As can be seen from the above description, the heat dissipation system 10 of the present invention can save the number of the fans 12, and the shape of the air hood 51 does not need to be specially designed, which can save a lot of manufacturing costs. To sum up, the present invention, regardless of its purpose, means and efficacy, shows its distinctive features of the prior art. You are requested to review the examinations and grant the patents as soon as possible. It is to be noted that the various embodiments described above are intended to be illustrative only, and the scope of the invention is intended to be limited by the scope of the appended claims.
