Description of the Invention: [Technical Field] The present invention relates to a heat dissipation system, and more particularly to a computer dustproof heat dissipation system. [Prior Art] With the continuous development of the electronics industry, the heat generated by electronic components in computer systems is increasing. The use of heat sinks alone cannot meet the heat dissipation requirements of electronic components such as central processing units in computer systems. The industry's usual solution to this problem is to install a cooling fan on the heat sink to accelerate air convection within the system and improve heat dissipation efficiency.

After passing through the fan and the heat sink, they will accumulate on the circuit board near the heat sink, jeopardizing the circuit board. The operational stability of the electronic components even causes damage to the electronic components. In order to timely remove the dust particles entering the computer case, keep the inside of the chassis clean, the performance of the electronic components on the circuit board is protected from dust particles and prolong the service life of the electronic components, people need to constantly open the computer case. After the dust particles in the standby box are removed, assemble the chassis. This is a very troublesome thing for computer users. In addition, the constant disassembly and assembly of the computer case also poses a risk of damaging the electronic components in the computer case. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a computer dustproof heat dissipation system. The electric thin p-fang dust political heat system includes a radiator, a fan and a fan installed inside the chassis, and the fan is mounted on the radiator, and the air inlet is provided on the side plate of the chassis, and a dust cover is detachably mounted on the chassis. The air inlet is covered on the side panel, and one end of the air duct is disposed on the fan, and the other end is connected with the air inlet = on the box, and a sealing from the air inlet to the radiator is compared with the conventional technology. The computer dust-proof and heat-dissipating system can prevent the dust particles outside the chassis from entering the ribs of the machine, effectively lifting the dust side, and keeping the dust-cleaning age [implementation method] Please refer to the first and second pictures of the computer The Weire system consists of a radiator 6 1298618 a dust cover 50. The dust cover is fixed on the side panel 40 of the computer case by a fan 20 and a duct 30, 50 on the radiator 1 . Referring to the second and third figures, the computer chassis side panel 40 is provided with a cold air outside the chassis to provide access to the inside of the chassis. The inlet σ 42 is one of the edges of the straight side panel 40. The side panel 4 of the chassis is provided with a joint edge 44 into the casing at the periphery of the air inlet 42. The joint edge 44 further extends two opposite lugs, and a lug 48 is provided on the ear 46. . The fan 20 is mounted on a heat sink. The heat sink 10 includes a plurality of radially fins 10.
該防塵罩5〇爲板狀，靠向其-端設有、開口並蒙設有渡網52，而 其另一端緣垂直延設有摺邊54,該摺邊54可與機箱之另_個側板（圖 未不）相抵靠。防塵罩50内側對應機箱侧板4〇上之扣孔牝設有彈 片58 (明參看第二圖）。防塵罩5〇兩侧緣可在進風口 42周緣之結合 邊44上滑行移動，並使彈片58於扣耳46上滑行而受到扣耳46 壓而變形，當防塵罩50滑到完全罩住進風口 42時，彈片58滑入扣 孔48内，由於不再受到擠壓而恢復原形並與扣孔牝配合，防塵罩 之兩側緣此則貼合於機箱侧板4〇之結合邊44上。當需要拆下防塵 罩50時，使彈片58脫離扣孔48 ,便可方便地將防塵罩5〇從機箱側 板40上取下來。防塵罩5〇外侧設有方便拆裝防塵罩5〇之凸肋％(請 參看第二圖）。可見，防塵罩50之彈片58可滑入或滑出扣孔48，從 而方便地安裝或拆卸防塵罩5〇。 所述風管30 —端罩設在風扇2〇上，另一端與機箱側板4〇上之 進風口 42相接並與濾網52相對，從而形成一個從進風口到散熱器之 密閉進風道，以便將進入機箱之冷空氣直接導入到風扇2〇 上，並經 風扇20集中地吹向散熱器1〇。機箱外之冷空氣首先經過防塵罩5〇 之渡網52濾塵，將其中之灰塵顆粒濾去後才從進風口 42進入機箱 内’有效保證進入機箱内之冷空氣之清潔度。 總之’該電腦防塵散熱系統之防塵罩5〇之濾網52可防止機箱外 灰塵顆粒進入機箱内部，有效地起到防塵之作用，保持機箱内之清 7 1298618 潔。另一方面，防塵罩50可方便地安裝到機箱上並可方便地從機箱 上拆卸下來以便清洗，不必打開整個機箱，因此，不會有破壞電腦機 箱内電子元件之危險。 【圖式簡單說明】 第一圖係本發明電腦防塵散熱系統之立體組合圖。 第二圖係第一圖之分解圖。 第三圖係本發明之電腦防塵散熱系統之防塵罩和電腦機箱側板 之立體分解圖。 【主要元件符號說明】、 散熱器 10 風扇 20 風管 30 機箱側板 40 進風口 42 結合邊 44 扣耳 46 扣孔 48 防塵罩 50 濾網 52 摺邊 54 凸肋 56 彈片 58 8The dust cover 5 is formed in a plate shape, and is disposed at an end thereof, opened and covered with a crossing net 52, and the other end edge thereof is vertically extended with a flange 54 which can be combined with another one of the chassis The side panels (not shown) are against each other. The inside of the dust cover 50 is provided with a spring 58 corresponding to the buckle hole on the side panel 4 of the chassis (see the second figure). The two sides of the dust cover 5 slidably move on the joint edge 44 of the periphery of the air inlet 42 and slide the elastic piece 58 on the buckle 46 to be deformed by the buckle 46, and the dust cover 50 slides completely into the cover. When the tuyere 42 is closed, the elastic piece 58 slides into the buckle hole 48, and is restored to the original shape and is matched with the buckle hole 不再, and the two sides of the dust cover are attached to the joint edge 44 of the chassis side plate 4〇. . When the dust cover 50 needs to be removed, the elastic piece 58 can be easily removed from the chassis side plate 40 by disengaging the elastic piece 58 from the fastening hole 48. The outer side of the dust cover 5 is provided with a rib % for easily attaching and detaching the dust cover 5 (please refer to the second figure). It can be seen that the elastic piece 58 of the dust cover 50 can slide into or out of the buckle hole 48, thereby conveniently installing or removing the dust cover 5〇. The air duct 30 is disposed on the fan 2〇, and the other end is connected to the air inlet 42 of the chassis side panel 4 and opposite to the screen 52, thereby forming a closed air inlet duct from the air inlet to the radiator. In order to directly introduce the cold air entering the chassis to the fan 2〇, and blow the fan 20 to the radiator 1 in a concentrated manner. The cold air outside the chassis first passes through the filter 52 of the dust cover 5〇, and the dust particles are filtered out before entering the chassis from the air inlet 42 to effectively ensure the cleanliness of the cold air entering the chassis. In short, the filter 52 of the dustproof cover of the computer can prevent dust particles from entering the inside of the chassis, effectively preventing dust and keeping the inside of the chassis clean. On the other hand, the dust cover 50 can be easily mounted to the chassis and can be easily removed from the chassis for cleaning without opening the entire chassis, so that there is no danger of damaging the electronic components in the computer case.
