需要說明的是，於該殼體101內設有待散熱組件（未在圖中示出），以透過該風冷散熱組件和該液冷散熱組件對該待散熱組件進行散熱；具體地，對於待散熱組件中的主要熱源利用該液冷散熱組件進行冷卻，其餘熱源採用該風冷散熱組件進行冷卻，透過這種混合製冷方式，可大幅提升散熱效率。It should be noted that a heat dissipation component (not shown in the figure) is provided in the housing 101, so that heat is dissipated from the heat dissipation component through the air-cooled heat dissipation component and the liquid-cooled heat dissipation component; specifically, the main heat source in the heat dissipation component is cooled by the liquid-cooled heat dissipation component, and the remaining heat sources are cooled by the air-cooled heat dissipation component. Through this hybrid cooling method, the heat dissipation efficiency can be greatly improved.
如圖1和圖2所示，於一實施例中，所述液冷散熱組件包括進液管102、出液管103及至少一組液冷板組（未在圖中示出）；每一所述液冷板組均分別與所述進液管102和所述出液管103連接。As shown in FIG. 1 and FIG. 2 , in one embodiment, the liquid cooling heat dissipation assembly includes a liquid inlet pipe 102 , a liquid outlet pipe 103 and at least one set of liquid cooling plate groups (not shown in the figure); each of the liquid cooling plate groups is connected to the liquid inlet pipe 102 and the liquid outlet pipe 103 , respectively.
如圖1和圖2所示，於一實施例中，每一所述液冷板組包括至少一液冷板104；所述液冷板104內為空心結構，用於存放冷液。As shown in FIG. 1 and FIG. 2 , in one embodiment, each of the liquid cooling plate assemblies includes at least one
需要說明的是，當所述液冷板組包括至少兩個所述液冷板104時，至少兩個所述液冷板104依次排列，且相鄰的兩個所述液冷板104之間透過柔性軟管105連接，以實現液冷板組的液冷板104之間的相互連通；其中，位於首端的液冷板104與所述進液管102連接，位於尾端的液冷板104與所述出液管103連接。It should be noted that when the liquid cooling plate group includes at least two

於一實施例中，當所述液冷板組的數量為至少兩組時，至少兩組所述液冷板組中的部分液冷板組形成第一冷板模組（未在圖中示出）；至少兩組所述液冷板組中，除用於形成所述第一冷板模組外的液冷板組形成第二冷板模組（未在圖中示出）。In one embodiment, when the number of the liquid cooling plate groups is at least two, some of the at least two groups of the liquid cooling plate groups form a first cold plate module (not shown in the figure); and among the at least two groups of the liquid cooling plate groups, the liquid cooling plate groups other than those used to form the first cold plate module form a second cold plate module (not shown in the figure).
如圖1所示，所述第一冷板模組用於為GPU模組201散熱；所述第二冷板模組用於為以太網交換機晶片202（NV SWITCH晶片）散熱。As shown in FIG. 1 , the first cold plate module is used to dissipate heat for the GPU module 201 ; the second cold plate module is used to dissipate heat for the Ethernet switch chip 202 (NV SWITCH chip).
需要說明的是，透過將本發明的散熱裝置應用於伺服器，對於該伺服器內的主要熱源（包括GPU模組201和以太網交換機晶片202）利用液冷板進行冷卻，其餘熱源仍採用風冷方式進行冷卻；透過這種混合製冷方式，可大幅提升該伺服器的散熱效率；同時，降低主要熱源GPU散熱所消耗電能，並增強伺服器的可靠性；另外，能很好的解決GPU散熱問題，最後可達到年平均PUE1.2以下。It should be noted that by applying the heat dissipation device of the present invention to a server, the main heat source in the server (including the GPU module 201 and the Ethernet switch chip 202) is cooled by a liquid cooling plate, and the remaining heat sources are still cooled by air cooling. Through this hybrid cooling method, the heat dissipation efficiency of the server can be greatly improved. At the same time, the power consumption of the main heat source GPU heat dissipation is reduced, and the reliability of the server is enhanced. In addition, the GPU heat dissipation problem can be well solved, and the annual average PUE can finally be achieved below 1.2.
如圖1和圖2所示，於一實施例中，所述液冷散熱組件還包括分水器106和至少一分液管組（未在圖中示出）。As shown in FIG. 1 and FIG. 2 , in one embodiment, the liquid cooling heat dissipation assembly further includes a water distributor 106 and at least one liquid distributor tube set (not shown in the figure).

如圖1所示，用於為GPU模組201散熱的第一冷板模組，與用於為以太網交換機晶片202散熱的第二冷板模組合二為一，分水器也只用了一個，滿足散熱性能的同時，減少了快接頭的使用，冷水優先透過功耗較大的GPU模組201，提高了整個液冷散熱組件的散熱性能。As shown in FIG1 , the first cold plate module for cooling the GPU module 201 is combined with the second cold plate module for cooling the Ethernet switch chip 202, and only one water distributor is used. While satisfying the heat dissipation performance, the use of quick connectors is reduced.

需要說明的是，隨著市場對伺服器性能要求的不斷提高，伺服器內部元件越來越多、分佈越來越密集，各元件的運行強度也不斷增加，這就造成系統內部產生的熱量越來越多，所以如何靈活運用伺服器內部的空間來提高各元件的散熱效率成為產品研發過程中面臨的重要問題；現有技術中，在伺服器中通常採用風扇進行散熱，利用風流將熱量帶走，但是，使用風扇進行散熱時通常面臨以下問題：It should be noted that as the market's requirements for server performance continue to increase, the number of internal server components is increasing, the distribution is becoming more and more dense, and the operating intensity of each component is also increasing, which causes more and more heat to be generated inside the system. Therefore, how to flexibly use the space inside the server to improve the heat dissipation efficiency of each component has become an important issue faced in the product development process; in the prior art, fans are usually used in servers for heat dissipation, using wind flow to take away the heat, but when using fans for heat dissipation, the following problems are usually faced:
（1）風流分配不合理，缺乏針對性。主板上各發熱元件的散熱需求不同，所需風量也不同，風流無法按需分配風量給各流道上的元件，致使散熱效果不佳；(1) The airflow distribution is unreasonable and lacks specificity. The heat dissipation requirements of the various heat-generating components on the motherboard are different, and the required air volume is also different. The airflow cannot be distributed to the components on each flow channel as required, resulting in poor heat dissipation effect;
（2）風量有效利用率低。風扇吹出的風流大多於各元件之間的空隙中流出，能夠在各元件表面起到散熱作用的風量有限；(2) The effective utilization rate of air volume is low. The air flow blown out by the fan mostly flows out from the gaps between the components, and the air volume that can dissipate heat on the surface of each component is limited;
（3）風流受空間佈局影響大。主板上各元件對風流也起到一定阻擋作用，所以在各元件間的空隙之間易形成旁流，風流相互干擾，影響散熱效果；(3) The airflow is greatly affected by the spatial layout. The components on the motherboard also have a certain blocking effect on the airflow, so it is easy to form side flow between the gaps between the components, and the airflow interferes with each other, affecting the heat dissipation effect;
（4）系統工作效率降低且存在對系統安全性的威脅。風量分佈不合理、散熱效果不佳等因素使得散熱元件表面的熱量無法及時散出，熱量堆積過多使得元件工作效率降低且有損壞的風險；(4) The system efficiency is reduced and there is a threat to system safety. Factors such as unreasonable air volume distribution and poor heat dissipation effect make it impossible for the heat on the surface of the heat dissipation component to be dissipated in time. Excessive heat accumulation reduces the efficiency of the component and poses a risk of damage;
（5）通用型導風罩無法精準導風。現有設計中的通用型導風罩結構單一，無法實現對散熱量需求大的元件進行精準導風，散熱效率無法達到要求。(5) Universal air ducts cannot accurately guide air. The existing universal air ducts have a simple structure and cannot accurately guide air for components with large heat dissipation requirements, and the heat dissipation efficiency cannot meet the requirements.
為解決上述問題，如圖1、圖3及圖6所示，本發明提供了一種風冷散熱組件；具體地，所述風冷散熱組件包括導風罩110和風冷機構111。To solve the above problems, as shown in FIG. 1 , FIG. 3 and FIG. 6 , the present invention provides an air-cooled heat dissipation assembly; specifically, the air-cooled heat dissipation assembly includes an air guide cover 110 and an air cooling mechanism 111 .
於一實施例中，所述導風罩110和所述風冷機構111均設於所述殼體101，其中，所述導風罩110用於將風流分別導向三個不同的導風流道，這三個導風流道分別對應殼體101的兩側及該殼體101後部（如圖3所示，殼體101的右側設有進風口，左側設有出風口，箭頭指明了風向）。In one embodiment, the air guide cover 110 and the air cooling mechanism 111 are both disposed on the shell 101, wherein the air guide cover 110 is used to guide the airflow to three different air guide channels, respectively, and the three air guide channels correspond to the two sides of the shell 101 and the rear of the shell 101, respectively (as shown in Figure 3, the shell 101 is provided with an air inlet on the right side and an air outlet on the left side, and the arrow indicates the wind direction).
具體地，在將本發明的散熱裝置應用於伺服器時，該導風罩110用於將風流分流導向伺服器機櫃兩側的VR及該機櫃後部的網卡（PCIe卡）處。Specifically, when the heat dissipation device of the present invention is applied to a server, the air guide cover 110 is used to divert the airflow to the VRs on both sides of the server cabinet and the network card (PCIe card) at the rear of the cabinet.
如圖6和圖7所示，於一實施例中，所述導風罩110包括第一導風塊1101、第二導風塊1102及第三導風塊1103。As shown in FIG. 6 and FIG. 7 , in one embodiment, the air guide cover 110 includes a first air guide block 1101 , a second air guide block 1102 and a third air guide block 1103 .
具體地，所述第二導風塊1102設於所述第一導風塊1101與所述第三導風塊1103之間，且所述第二導風塊1102的高度低於所述第一導風塊1101和所述第三導風塊1103。Specifically, the second air guide block 1102 is disposed between the first air guide block 1101 and the third air guide block 1103 , and the height of the second air guide block 1102 is lower than that of the first air guide block 1101 and the third air guide block 1103 .

具體地，如圖6和圖7所示，沿著殼體101寬度方向，導風罩110在空間上的高低分佈，將導風罩110分為三個區域，分別為第一導風塊1101、第二導風塊1102及第三導風塊1103；其中，第一導風塊1101和第三導風塊1103的塊狀結構相比中間區域的第二導風塊1102更加高，以便於將風導向VR Heatsink處，從而改善其換熱效果；而第二導風塊1102沿殼體101長度方向則做了兩次的階梯狀下壓設計，主要是為了將氣流壓低至與後方PCIe卡相近的高度區間內，從而提高後方卡區的氣流流量。Specifically, as shown in Figures 6 and 7, along the width direction of the shell 101, the air guide cover 110 is spatially distributed in height, dividing the air guide cover 110 into three areas, namely the first air guide block 1101, the second air guide block 1102 and the third air guide block 1103; wherein, the block structure of the first air guide block 1101 and the third air guide block 1103 is higher than the second air guide block 1102 in the middle area, so as to facilitate directing the wind to the VR Heatsink, thereby improving its heat exchange effect; and the second air guide block 1102 has two stepped downward pressure designs along the length direction of the shell 101, mainly to compress the airflow down to a height range close to the rear PCIe card, thereby increasing the airflow flow in the rear card area.
於一實施例中，所述導風罩110為整體式結構，其透過螺絲鎖附在整個殼體101上。In one embodiment, the air guide cover 110 is an integral structure, which is fastened to the entire housing 101 by screws.

需要說明的，該導風罩110順應伺服器機櫃內部各元件的空間佈局，VR處導風罩設計高度較低，將風流最大可能壓至VR處；另外，順應分液管組（包括進液分液管107和出液分液管108）的分佈，設計了斜面對網卡進行導風，從而最大程度地利用了風量，使VR及網卡實現高效散熱，達到了以下技術效果：It should be noted that the air guide cover 110 complies with the spatial layout of the components inside the server cabinet, and the height of the air guide cover at the VR is designed to be relatively low, so that the airflow is pressed to the VR as much as possible; in addition, in accordance with the distribution of the liquid distribution pipe group (including the liquid inlet distribution pipe 107 and the liquid outlet distribution pipe 108), an inclined surface is designed to guide the air to the network card, thereby maximizing the use of the air volume, so that the VR and the network card can achieve efficient heat dissipation, and achieve the following technical effects:
（1）合理分配風流。導風罩起分流作用，將風流導至各流道中，根據不同流道中不同的散熱需求設計不同的形狀結構進行導風。(1) Reasonable distribution of airflow. The air guide hood plays a role in diverting the airflow to each flow channel. Different shapes and structures are designed to guide the air according to the different heat dissipation requirements in different flow channels.

（3）避免形成亂流。各風道相互獨立，互不干擾，避免了旁流及亂流的產生，減少資源浪費。(3) Avoid the formation of chaotic flow. Each air duct is independent of each other and does not interfere with each other, thus avoiding the generation of side flow and chaotic flow and reducing resource waste.
（4）延長伺服器工作壽命。使用導風罩可顯著增強各元件散熱效果，避免了熱量堆積對元件帶來的損害，提高工作效率的同時避免了損壞的風險。(4) Extend the service life of the server.

（5）結構簡單，易於製作，成本低。(5) Simple structure, easy to manufacture and low cost.
於一實施例中，所述導風罩110採用成本低廉的麥拉（Mylar）材料製成，相比聚碳酸酯材質（PC）的導風罩，麥拉材質的導風罩無需開模，製作簡單，經濟效益明顯。In one embodiment, the air guide cover 110 is made of low-cost Mylar material. Compared with the air guide cover made of polycarbonate (PC), the air guide cover made of Mylar material does not need to be molded, is simple to manufacture, and has obvious economic benefits.
