如「第1圖」至「第3圖」所示，為本發明之一實施例所 揭露的導風裝置10，其包括有一本體110及一導風板12〇，本 體110及導風板120的組成材料可以是但不侷限於以金屬材料 或塑膠材料所組成。本體110具有一頂板U1及一底板112， 並且本體於頂板111的相對二侧分別具有一折邊113，二折邊 113係連接於頂板111及底板U2之間，其中每一折邊丨13的 相對二端分別設置有一凹口 1131及一扣片1132，用以和電子 裝置的機殼(圖中未示)相互結合。 本體110之頂板111具有一開口 114，開口 114係介於二 折邊113之間，並且本體11〇於開口 114内的相對二側面分別 设置有-滑行軌道115 ’滑行執道115是由一設置於側面上的 凸緣116與底板112之間所界定形成的移動路徑，並且於滑行 執道115内設置有至少一定位孔117。此外，頂板ηι對應於 底板112的位置處連接有—擋板118，擋板118係連接於頂板 111相鄰於開口 114之一侧邊，並且擋板118朝開口 114方向 傾斜設置於頂板111與底板m之間，並同時介於二滑行執道 115之間。其中’擋板118及底板112之間具有一間隙(圖中未 示）’導風板120之-端係穿過播板118及底板112之間的間 201244616 隙而位於頂板m下方，並且承載於底板112上，導風板⑽ 的另一端則露出於開口 114内。 導風板120的姆二側邊分別卡合於=滑行軌道出，使 導風板120活動設置於本體11〇上，並可沿二滑行執道⑴於 開口丨14内相對本體110位移至一開啟位置P1，或者是位移 至一導流位置。當導風板120位於開啟位置P1，導風板12〇 係部分沒入於本體110内，使開口 114露出於(或貫穿過)本體 110 ;以及當導風板120位於導流位置P2，導風板12〇係沿著 二滑行軌道115自本體110内伸出，並遮蔽住開口 114。 導風板120具有二彈片12卜至少一止擋件122及一限位 件123 ’ 一彈片121分別設置於導風板120對應於二滑行軌道 115的相對二側邊，並且於每一彈片121上設置有一抵頂件 124，抵頂件124可以是但並不侷限於自彈片121上延伸形成 的凸塊。同時，抵頂件124係藉由彈片121本身所具有的彈性 力’常態的抵頂(或抵緊)於滑行軌道115上。止擋件⑵設置 於導風板120位於頂板ill下方之一端(即位於擋板118遠離 開口 114之一側），限位件123則設置於導風板12〇露出於開 . 口 114之一端(即擋板118相鄰於開口 114之一側）。 . 因此’當導風板120於本體110上位移至開啟位置P1時， 導風板120可藉由限位件123抵靠於擋板118相對開口 114之 一側面’使導風板120被暫時地限位於開啟位置pi上，以避 免^r風板120持績滑動而脫離於本體110。同樣地，當導風板 201244616 120於本體no上位移至導流位置p2時’導風板12〇可藉由 止擒件122抵靠於擋板Π8相對開口 114之另一側，使導風板 120受到擋板118的止擋作用，而被限位於導流位置p2，以避 免導風板120自開口 114處脫離於本體no。 此外，當導風板120位於導流位置P2時，位於導風板12〇 上的抵頂件124係順勢的滑移並卡合於滑行執道115的定位孔 117内，使導風板12〇於本體11〇上自由位移的能力受到限制， 而被暫時地固定於導流位置p2，如此可避免導風板12〇在遭 又不預期外力作用時，容易脫離於導流位置p2的情形發生。 請參閱「第2圖」至「第7圖」，在應用上，導風裝置1〇 係裂設於-f子裝置的機殼2G上，在本實酬巾係以抽拉式 的伺服益機殼做為舉例說明，但並不以此為限。機殼2〇具有 一進風口 210及一出風口 220,進風口 210及出風口 220分別 開。又於機殼20的相對二側面，並且於機殼2〇内設置有至少一 風扇230及一電路板24〇，電路板24〇上電性設置有至少一電 子元件250 ’在本實施例中，是以電路板240上電性設置有複 數個記憶體做為舉例，但並不以此為限 。風扇230及電路 板2仙係沿著進風口 21〇朝出風口 no的方向設置，其中風扇 230貼近於進風σ 21()，並且與電路板相隔—預定距離， 風=30係用以將外界空氣自進風口別抽入機殼2()内以產 ，並將此氣流傳送至電路板24〇。之後，氣流再經由 出風口 220流出至機殼20外。 201244616 此外’機殼20另具有一蓋板260，蓋板260樞設於機殼 20上相鄰於出風口 220之一側，並且可相對機殼2〇轉動而蓋 合於機殼20上，而遮蔽部分電路板24〇及電子元件25〇。同 時，機殼20内的相對二壁面270設置有一樞軸280及一扣環 290，樞軸280係設置於機殼20内相鄰於風扇23〇之一側，扣 環290則設置於機殼2〇内相鄰於電路板24〇之一側。導風裝 置10之凹口 1131及扣片1132即分別對應於機殼2〇之樞軸 280及扣環290。 因此’當導風裝置10裝設於機殼2〇時，係以本體η。之 凹口 1131卡合於機殼20之樞軸280，並可藉由樞軸28〇相對 機殼20轉動而蓋合於機殼2〇上，以藉由本體丨1〇之扣片丨132 嵌入於機殼20之扣環290内，使本體110懸置於風扇23〇及 電路板240之間。並且，本體ι1〇亦可藉由凹口 1131相對樞 軸280轉動，而令扣片1132自扣環290内抽出，以便於使本 體110之凹口 1131自樞軸280上脫離。因此，本體11〇可藉 由凹口 1131及扣片1132分別與機殼20之樞軸28〇及扣環2% 相互配合的作動方式，而可拆卸的結合於機殼20上。 當導風裝置10於機殼20上裝設完成後，使用者可將機殼 2〇之蓋板260蓋合於機殼20上。此時，電路板24〇上部分的 電子元件250受到蓋板260遮蔽，另一部分的電子元件25〇則 露出於導風裝置10的開口 114内(如「第5圖」所示）。接著， 在電子元件250開始運作前，使用者可拉掣導風裝置1〇的導 11 201244616 風板120，使導風板12〇自開啟位置ρι位移至導流位置p2， 並藉由抵頂件124卡合於滑行執道115之定位孔117而固定於 導流位置P2上。此時，導風板12〇遮蔽住開口 114，並懸置 於未爻到蓋板260遮蔽的電子元件250上方，使導風板120及 蓋板260罩覆住電路板240上所有的電子元件250，並且於機 设20内形成—氣流導引通道。 泣，s風扇230開始運轉而在機殼2〇内產生氣流時， 此氣流係沿著導風板120&蓋板26〇所形成的氣流導引通道直 接的傳送至電子元件25Q上，使氣流於電子元件表面進行 ’’’、又換作用。並且，使熱交換完成後的氣流被強制的從出風口 220流出於機殼2〇外，進而使機殼2()内部形成—穩定的氣流 ,穷而具有良好的熱父換效果。同時，由於導風裝置1〇之 擔扳118係傾斜設置於本體11〇上，如此，使導風裝置ι〇於 機殼20内所形成的氣流導引路徑形成自進風口朝出風口漸縮 贿梯式排列，而具有類似於喷嘴的結獅態。因此，當氣流 又到導風健1G之跳118的導引，而進人導顺與蓋板 形成的氣流導引通道時，將可加速氣流的流動速率，而提 流於機殼内的熱交換效率。 虱 另外，當使用者必需對電路板24〇上的電子元件ho進〜 維t或更換時，使用者只需將蓋板細自機殼 =施加—外力將導風裝置10之導風板12Q自導流位& 開啟位置P1，使電路板⑽上的電子轉250露出於 201244616 開口 114。如此’電子元件25〇可不受阻礙的經由開口川安 裝於電路板24〇上或者是從電路板上拆除，意即讓使用者 可直接的經由開π 114在電路板鳩上進行電子元件25〇的維

推動，即可使電路板上欲進行維修或更換的電子元件25〇 . 露出於開口 114，而省略開啟蓋板的操作程序，可進一步增進 使用者在更換及維修電子元件250的操作效率。 如「第10圖」所*，為本發明第三實施例所揭露的導風 裝置。本發明所揭露的第三實施例與第-實施例在結構上大致 13 201244616 相同，以下僅就兩者間的差異加以說明。在本發明所揭露的第 二貫施例中’本體110之開口 114内的相對二側面皆設置有二 凸緣116，二凸緣116係間隔設置於每一側面上，藉以在本體 110之開口 114内形成二相互對應的滑行軌道115，因此在本 體110上省略了底板112的設置。此外，每一滑行轨道115上 設置有二定位孔117，二定位孔in分別對應於導風板12〇的 開啟位置P1及導引位置P2上。因此，當導風板12〇滑移至開 啟位置P1或導引位置P2時，導風板12〇可藉由抵頂件124 卡合於相對應的定位孔117内，以限制導風板12〇相對本體 110.自由位移的能力，使導風板120可暫時的被固定於開啟位 置P1或導引位置P2,而常態的露出開σ 114或遮蔽住開口 114，進而省略止擋件122及限位件12；3的設置。 本發明之功效在於，導風裝置可藉由導風板在本體上往復 位移，而同時能達到導引氣流吹送電子元件以及讓使用者便於 自電路板上維修及更換電子元件的功效。當導驗位於導流位 置％導風板懸置於電路板之電子元件的上方，並且於機殼内 部形成-氣流導f丨通道，使風扇所產生的氣流被強制導引至電 子元件的設置位置，可增加電子元件的降溫效率。同時，當導 風板位於開啟位置時，電子元件在不需從機殼上拆除導風裝置 的情形下，便能直接的經由本體的開口，自電路板上進行維修 或更換，除了可大幅降低電子元件遭受不預期的碰撞而損壞之 外，並可增進維修及更換電子元件的工作效率。 14

Description of the invention: [Technical field to which the invention pertains] The present invention relates to a material position, which is an air guiding device which is difficult to be disposed on a casing of an electronic device for guiding an air flow inside the casing. [Prior Art] - Shouting 1 child (4) rapid development, making the computer processing speed (such as desktop computer or ship, etc.) more efficient, and the computer system's scheduling ability is constantly improving. At the same time, in order to meet the consumer's (four) processing speed requirements, in order to be able to provide information flow in a short time, so in most computer systems, the central processor (Ce_ p_ssing (10), pieces to increase the computer The data processing speed of the system and the purpose of multi-function computing. However, as the number of electronic components in the computer system increases, when the computer system is in a fully negative state, the heat source generated by these electronic components also increases. Failure to disperse in time may lead to a crisis in computer systems. Therefore, how to solve the problem of heat dissipation of electronic components inside computer systems has become an important issue. In order to solve the problem of heat dissipation inside the computer system, most of the current industry adopts The air hood is arranged inside the casing of the computer system, and the hood is installed inside the casing, so that one end of the air hood is connected to the cooling fan provided inside the casing, and the other end is directly Corresponding to the electronic components on the circuit board or the cover over the electronic components, so that the airflow generated by the cooling fan can Blowing to the electronic 201244616 = piece 'and by forced convection, the air flow on the surface of the electronic component for hot father change' in order to reduce the operating temperature of the electronic component, so that the f sub-component can operate at a stable operating temperature. The installation method of the current air hood in the casing usually needs to be locked to the bottom of the casing by means of a plurality of locking elements such as screws, bolts or bolts or directly locked on the circuit board, so as to be stable. The windshield is fixed in the casing, which tends to make the air guiding hood difficult and difficult to install and remove. In contrast, when the user needs to repair and replace the electronic components installed on the circuit board, 'Users need to -- remove most of the locking 7G parts that are locked at the bottom of the circuit test, and then remove the air hood from the casing to facilitate the repair and replacement of electronic components. This is not only easy to cause the board or electronic components to be damaged by collision when operating in the private valley, but also causes inconvenience in the maintenance and replacement of electronic components, resulting in work efficiency. In view of the above problems, the present invention provides an air guiding device for improving the casing of an electronic device provided with a wind deflector, and performing maintenance on electronic components of the circuit board. The replacement work towel 'accepts the bribe of the air hood, which causes the work of repairing and replacing the electronic components to be inefficient, time-consuming, and easy to cause the electronic components to be damaged by collision. The present invention discloses an air guiding device, which is installed. On the casing of an electronic device, the casing has at least one fan and a circuit board, and the circuit board is electrically provided with one electronic component to 201244616, and the fan is connected to the casing to generate an air flow. The device comprises between the body and the air deflector, the body has an opening corresponding to the electronic component, and the opposite sides of the opening respectively have a sliding track. The guiding side is opposite to the two sides. The sides are respectively engaged with the two sliding guides, and the wind deflecting plate can be reciprocally displaced along the two sliding rails between the opening_the body-and the guiding position and the -opening position. Wherein, when the air deflector is located at the flow guiding position, the air deflector shields the opening and is suspended above the electronic component to guide the airflow to the electronic component; when the air deflector is in the open position, the electronic component is exposed in the opening, And the electronic component can be detached from the casing via the opening. The effect of the invention is that when the air deflector is displaced to the guiding position on the body, the airflow generated by the fan can be forcibly guided to the electronic component by the air guiding channel formed in the wind deflector _ housing to reduce The operating temperature of the electronic components and maintain the operational efficiency of the electronic components. At the same time, when the air deflector is displaced to the open position on the body, the user can directly carry out the electronic components on the circuit board through the opening on the body of the air guiding device without removing the air guiding device from the casing. Maintenance and replacement work can not only improve the maintenance and replacement efficiency of electronic components, but also reduce the chances of improper handling of improper collisions. The above description of the present invention and the following description of the embodiments are used to transfer the invention to the present invention and to provide further explanation for the scope of the present patent application. [Embodiment] The wind guiding skirt disclosed in the present invention is installed on a mine of an electronic skirt (for example, a desktop type 201244616 computer and a 錬n, etc.), and (4) guiding an air blowing in the casing of the electronic device. The electronic components, such as electronic components such as a central processing unit and a memory, are used to reduce the operating temperature of the electronic components during operation to maintain the operational efficiency of the electronic components. As shown in FIG. 1 to FIG. 3, an air guiding device 10 according to an embodiment of the present invention includes a body 110 and a wind deflector 12, a body 110 and a wind deflector 120. The constituent material may be, but not limited to, a metal material or a plastic material. The main body 110 has a top plate U1 and a bottom plate 112, and the body has a flange 113 on opposite sides of the top plate 111, and the two folded edges 113 are connected between the top plate 111 and the bottom plate U2, wherein each of the flanges 13 is A notch 1131 and a buckle 1132 are respectively disposed on the opposite ends for coupling with the casing (not shown) of the electronic device. The top plate 111 of the body 110 has an opening 114, and the opening 114 is between the two folded edges 113, and the opposite sides of the body 11 are respectively disposed on the opposite sides of the opening 114. The sliding track 115 is arranged by a setting. A movement path defined between the flange 116 on the side and the bottom plate 112 is defined, and at least one positioning hole 117 is disposed in the taxiway 115. In addition, the top plate η is connected to the bottom plate 112 at a position where the baffle 118 is connected, the baffle 118 is connected to the top plate 111 adjacent to one side of the opening 114, and the baffle 118 is obliquely disposed on the top plate 111 toward the opening 114. Between the bottom plates m and at the same time between the two taxiing lanes 115. Wherein, there is a gap between the baffle 118 and the bottom plate 112 (not shown). The end of the air deflector 120 passes through the gap between the broadcast plate 118 and the bottom plate 112 and is located below the top plate m and is carried. On the bottom plate 112, the other end of the air deflector (10) is exposed in the opening 114. The two sides of the air deflector 120 are respectively engaged with the = sliding track, so that the wind deflector 120 is movably disposed on the body 11 ,, and can be displaced to the body 110 along the two sliding lanes (1) in the opening 丨 14 The position P1 is opened or displaced to a flow guiding position. When the air deflector 120 is located at the open position P1, the wind deflecting plate 12 is partially recessed into the body 110, so that the opening 114 is exposed (or penetrates) through the body 110; and when the air deflector 120 is located at the diversion position P2, The windshield 12 is extended from the body 110 along the two sliding rails 115 and shields the opening 114. The wind deflector 120 has two elastic pieces 12, at least one stop member 122 and one limiting member 123'. The elastic piece 121 is respectively disposed on the opposite side edges of the air guiding plate 120 corresponding to the two sliding tracks 115, and is disposed on each of the elastic pieces 121.

The ground limit is located at the open position pi to prevent the wind plate 120 from slipping out of the body 110. Similarly, when the air deflector 201244616 120 is displaced on the body no to the flow guiding position p2, the air deflector 12 can be abutted against the other side of the baffle cymbal 8 relative to the opening 114 by the retaining member 122, so that the wind deflector The plate 120 is blocked by the baffle 118 and is limited to the flow guiding position p2 to prevent the wind deflector 120 from being disengaged from the body no from the opening 114. In addition, when the air deflector 120 is located at the diversion position P2, the abutting member 124 located on the air deflector 12 is slipped and engaged with the positioning hole 117 of the taxiway 115, so that the wind deflector 12 is disposed. The ability to freely displace the body 11〇 is limited, and is temporarily fixed to the flow guiding position p2, so that the wind deflector 12 can be prevented from being easily separated from the guiding position p2 when it is subjected to an unexpected external force. occur. Please refer to "Fig. 2" to "Fig. 7". In the application, the air guiding device 1 is split on the casing 2G of the -f sub-assembly, and the servo-drawing servo is used in the actual payment. The case is illustrated as an example, but not limited to this. The casing 2 has an air inlet 210 and an air outlet 220, and the air inlet 210 and the air outlet 220 are respectively opened. Further, on the opposite sides of the casing 20, at least one fan 230 and a circuit board 24 are disposed in the casing 2, and the circuit board 24 is electrically disposed with at least one electronic component 250'. In this embodiment, The circuit board 240 is electrically provided with a plurality of memories as an example, but is not limited thereto. The fan 230 and the circuit board 2 are disposed along the air inlet 21 〇 toward the air outlet no, wherein the fan 230 is close to the intake air σ 21 () and is separated from the circuit board by a predetermined distance, and the wind is 30 for The outside air is drawn into the casing 2 () from the air inlet to be produced, and the air is sent to the circuit board 24 〇. Thereafter, the airflow flows out of the casing 20 through the air outlet 220. In addition, the casing 20 has a cover plate 260. The cover plate 260 is pivotally disposed on one side of the casing 20 adjacent to the air outlet 220, and is rotatable relative to the casing 2 to cover the casing 20. The shielding portion of the circuit board 24 and the electronic component 25 are shielded. At the same time, the opposite wall 270 of the casing 20 is provided with a pivot 280 and a buckle 290. The pivot 280 is disposed in the casing 20 adjacent to one side of the fan 23, and the buckle 290 is disposed on the casing. 2〇 is adjacent to one side of the circuit board 24〇. The notch 1131 and the cleat 1132 of the air guiding device 10 correspond to the pivot 280 and the buckle 290 of the casing 2 respectively. Therefore, when the air guiding device 10 is mounted on the casing 2, the body η is used. The recess 1131 is engaged with the pivot 280 of the casing 20 and can be closed on the casing 2 by the rotation of the pivot 28 〇 relative to the casing 20 to be fastened by the body 丨 132 The body is suspended from the buckle 290 of the casing 20 such that the body 110 is suspended between the fan 23 and the circuit board 240. Moreover, the body ι1〇 can also be rotated relative to the pivot 280 by the notch 1131, so that the buckle 1132 is pulled out from the buckle 290 to disengage the notch 1131 of the body 110 from the pivot 280. Therefore, the main body 11 can be detachably coupled to the casing 20 by the action of the recess 1131 and the cleat 1132 respectively engaging with the pivot 28 机 of the casing 20 and the retaining ring 2%. After the air guiding device 10 is installed on the casing 20, the user can cover the casing 260 of the casing 2 to the casing 20. At this time, the electronic component 250 of the upper portion of the circuit board 24 is shielded by the cover 260, and the other electronic component 25 is exposed to the opening 114 of the air guiding device 10 (as shown in Fig. 5). Then, before the electronic component 250 starts to operate, the user can pull the guide 11 201244616 wind deflector 120 of the air guiding device 1 to displace the wind deflector 12 from the open position ρι to the diversion position p2, and The member 124 is engaged with the positioning hole 117 of the taxiway 115 and fixed to the flow guiding position P2. At this time, the air deflector 12 occludes the opening 114 and is suspended above the electronic component 250 that is not covered by the cover 260, so that the wind deflector 120 and the cover 260 cover all the electronic components on the circuit board 240. 250, and formed in the machine 20 - air flow guiding channel. When the singer 230 starts to operate and generates airflow in the casing 2, the airflow is directly transmitted to the electronic component 25Q along the airflow guiding passage formed by the wind deflector 120& Perform ''' on the surface of the electronic component and change it. Further, the airflow after the completion of the heat exchange is forcibly flowed out of the casing 2 from the air outlet 220, thereby forming a stable airflow inside the casing 2 (), and has a good heat-following effect. At the same time, since the air deflector 1 is disposed obliquely on the body 11〇, the airflow guiding path formed by the air guiding device in the casing 20 is formed to be tapered from the air inlet toward the air outlet. The bribe is arranged in a ladder and has a lion-like state similar to a nozzle. Therefore, when the airflow is guided to the hopping 118 of the wind guide 1G, and the air guiding channel formed by the guide and the cover plate is accelerated, the flow rate of the airflow can be accelerated, and the heat in the casing is extracted. Exchange efficiency. In addition, when the user has to replace or replace the electronic component ho on the circuit board 24, the user only needs to thin the cover plate from the casing = apply - external force to guide the wind deflector 12Q of the air guiding device 10. The self-guided flow & open position P1 causes the electron turn 250 on the board (10) to be exposed to the 201244616 opening 114. Thus, the electronic component 25 can be mounted on the circuit board 24A via the opening without being hindered or removed from the circuit board, that is, the user can directly perform the electronic component 25 on the circuit board via the opening π 114. The repair and replacement can be performed without first removing the wind guide 10 from the casing 20, thereby increasing the convenience of the electronic component 250 during replacement or maintenance. In the first embodiment of the present invention, the air deflector 12 of the air guiding device 1 is covered with the cover of the casing 2 to cover the circuit board 240. An airflow guiding channel is formed in the crucible. However, in the other embodiments of the present invention, the area of the wind deflector 120 of the air guiding device ig may be increased, and the arrangement of the cover plate may be omitted. As shown in "Fig. 8" and "Fig. 9", in the air guiding device 10 disclosed in the second embodiment of the present invention, the length of the sliding track of the air guiding device 1 is extended to be adjacent to the machine. At the position of the exit wind σ 22G of the shell 2, and amplifying the area of the wind deflector 120, when the wind deflector 12 is displaced from the open position to the flow guiding position P2, the circuit board 24 can be completely covered, and An air guide channel is formed in the casing 2〇. Therefore, when the electronic component MO on the circuit board 24 needs to be repaired and replaced, the user only needs to push the air deflector 12 toward the opening position, and the battery board can be repaired or replaced. The electronic component 25 is exposed to the opening 114, and the operation procedure of opening the cover is omitted, which further enhances the operation efficiency of the user in replacing and repairing the electronic component 250. The "window 10" is a wind guiding device disclosed in the third embodiment of the present invention. The third embodiment disclosed in the present invention is the same as the first embodiment in the structure of substantially 13, 201244616, and only the differences between the two will be described below. In the second embodiment of the present invention, the opposite sides of the opening 114 of the body 110 are provided with two flanges 116. The two flanges 116 are spaced apart from each other to form an opening at the body 110. Two mutually corresponding sliding rails 115 are formed in the 114, so that the arrangement of the bottom plate 112 is omitted on the body 110. In addition, each of the sliding rails 115 is provided with two positioning holes 117, and the two positioning holes in respectively correspond to the opening position P1 and the guiding position P2 of the wind deflector 12A. Therefore, when the air deflector 12 is slid to the open position P1 or the guiding position P2, the air deflector 12 can be engaged with the corresponding positioning hole 117 by the abutting member 124 to restrict the wind deflector 12 The ability of the air deflector 120 to be temporarily fixed to the open position P1 or the guide position P2, and the normal exposed σ 114 or the opening 114, thereby omitting the stopper 122 and The setting of the limiting member 12; The effect of the present invention is that the air guiding device can be reciprocally displaced on the body by the air deflector, and at the same time, it can achieve the function of guiding the airflow to blow the electronic components and allowing the user to easily repair and replace the electronic components from the circuit board. When the guide is located at the flow guiding position, the air deflector is suspended above the electronic components of the circuit board, and an air flow guide channel is formed inside the casing, so that the airflow generated by the fan is forcibly guided to the electronic component. The position can increase the cooling efficiency of the electronic components. At the same time, when the air deflector is in the open position, the electronic component can be directly repaired or replaced from the circuit board through the opening of the body without removing the air guiding device from the casing, except that the electronic component can be greatly reduced. Electronic components are damaged by unintended collisions and can increase the efficiency of repairing and replacing electronic components. 14 201244616 Although the embodiments of the present invention are disclosed above, it is not intended to limit any of the skill of the present invention, and it is not necessary to deny the spirit and scope of the present invention.
