本創作提供一種內建有泵浦的水冷頭。請參照第1圖，其為本創作水冷頭於一實施例的結構示意圖。水冷頭1包括一殼體2、一底座3以及一泵浦4，且殼體2包括有一工作流體入口21以及一工作流體出口22，而工作流體入口21與工作流體出口22用以與其他散熱裝置例如水冷排或是管路連接，進而供工作流體(圖中未示)流入殼體2內或向殼體外流出。又，底座3的外側具有一吸熱底面31，而內側則設置或是形成有一傳熱結構32，當吸熱底面31與發熱源(圖中未示)接觸後，會吸收其熱能並傳遞至傳熱結構32，傳熱結構32則會透過與工作流體(圖中未示)的接觸而將熱能傳遞至工作流體。 This creation provides a water cooling head with a built-in pump. Please refer to FIG. 1, which is a schematic structural diagram of an embodiment of a water cooling head. The water cooling head 1 includes a casing 2, a base 3, and a pump 4, and the casing 2 includes a working fluid inlet 21 and a working fluid outlet 22, and the working fluid inlet 21 and the working fluid outlet 22 are used for heat dissipation with other The device is, for example, a water-cooled drain or a pipe connection, so that a working fluid (not shown) flows into the housing 2 or flows out of the housing. In addition, the outer side of the base 3 has a heat-absorbing bottom surface 31, and the inner side is provided or formed with a heat transfer structure 32. When the heat-absorbing bottom surface 31 is in contact with a heat source (not shown), it will absorb its heat energy and transfer it to the heat transfer The structure 32 and the heat transfer structure 32 transfer heat energy to the working fluid through contact with the working fluid (not shown).

其中，底座3的傳熱結構32，可選擇切削式鰭片(skived fin)，或是其他柱狀、片狀、甚至於是不規則的形狀的鰭片，只要能夠增加與工作流體接觸的面積，就可讓熱能更快傳遞至工作流體。而當殼體2跟底座3藉由鎖固或其他固定手段結合在一起後，就可界定出一可供工作流體流動的作用空間5。 Among them, the heat transfer structure 32 of the base 3 can be selected from skived fins or other columnar, sheet-like, or even irregular-shaped fins, as long as it can increase the area of contact with the working fluid, This allows heat to be transferred to the working fluid more quickly. When the housing 2 and the base 3 are combined together by locking or other fixing means, a working space 5 for working fluid flow can be defined.

此外，作用空間5包括一吸熱空間51、一通道52以及一排水空間53，其中吸熱空間51連接工作流體入水口21，排水空間53連接工作流體出水口22，而通道52則連接吸熱空間51與排水空間53。而從結構上來劃分，通道52以及排水空間53位於殼體2的內部，屬於殼體2內的結構，而吸熱空間51則由殼體2與底座3兩者所共同界定而成。 In addition, the working space 5 includes a heat absorption space 51, a channel 52, and a drainage space 53, wherein the heat absorption space 51 is connected to the working fluid inlet 21, the drainage space 53 is connected to the working fluid outlet 22, and the channel 52 is connected to the heat absorption space 51 and Drainage space 53. In terms of structure, the channel 52 and the drainage space 53 are located inside the housing 2 and belong to the structure inside the housing 2. The heat absorption space 51 is defined by both the housing 2 and the base 3.

另外，在垂直方向上，殼體2係在排水空間53與吸熱空間51之間，也就是通道52的外圍，從外側向內凹設一機電腔23，機電腔23獨立於作用空間5，不與作用空間5有任何水路上的連通，因此不會接觸到工作流體。而本實施例所提供將機電腔23設置於殼體2中段位置的設計，除了提供電氣元件在空間布局時的另一種選擇外，也可降低水冷頭1整體的高度。 In addition, in the vertical direction, the housing 2 is located between the drainage space 53 and the heat absorbing space 51, that is, the periphery of the channel 52, and an electromechanical cavity 23 is recessed from the outside to the inside. The electromechanical cavity 23 is independent of the working space 5, not There is any waterway communication with the working space 5, so there is no contact with the working fluid. The design of the electromechanical cavity 23 provided in the middle position of the casing 2 provided in this embodiment, in addition to providing another option for the layout of electrical components in space, can also reduce the overall height of the water cooling head 1.

此外請參考第1圖與第2圖，泵浦4包含有一樞轉部41、一第一磁性元件42、一第二磁性元件43、一扇葉部44以及一電路板46。其中電路板46係與第一磁性元件42電性連接，並且電路板46以及第一磁性元件42係設置在工作流體流動的作用空間5外。在本實施例中，第一磁性元件42係設置於前述所提的機電腔23內，而電路板46則可設置在殼體2的上方或是其他適當的位置例如殼體2的旁側，並且與第一磁性元件42電性連接。樞轉部41、第二磁性元件43以及扇葉部44則設置在工作流體流動的作用空間5內，其中，扇葉部44位在排水空間53內，樞轉部41則自排水空間53延伸至通道52內。在結構上，樞轉部41係連接於扇葉部44，在垂直於底座的方向上係位在扇葉部44與底座3之間。扇葉部44具有複數扇葉441。第二磁性元件43係設於扇葉部44及/或樞轉部41上，第1圖所顯示的水冷頭1係第二磁性元件43設於樞轉部41上並且位在通道52內的情況。此外，第一磁性元件42可選自矽鋼片或是磁鐵，第二磁性元件43可選自一磁鐵，但不以上述為限。而在電路板46、第一磁性元件42以及第二磁性元件43的共同作用下，樞轉部41與扇葉部44可被驅動旋轉，進而引導工作流體的移動，特別是將工作流體從吸熱空間51經由通道52而向上導引至排水空間53。特別說明的是，於本案創作中，第一磁性元件42在垂直於底座的方向上是位於扇葉部44與底 座3之間，亦位於工作流體入口21以及工作流體出口22之間。 In addition, referring to FIGS. 1 and 2, the pump 4 includes a pivoting portion 41, a first magnetic element 42, a second magnetic element 43, a blade portion 44 and a circuit board 46. The circuit board 46 is electrically connected to the first magnetic element 42, and the circuit board 46 and the first magnetic element 42 are arranged outside the working space 5 where the working fluid flows. In this embodiment, the first magnetic element 42 is disposed in the aforementioned electromechanical cavity 23, and the circuit board 46 may be disposed above the housing 2 or at another suitable location such as the side of the housing 2, And it is electrically connected to the first magnetic element 42. The pivoting portion 41, the second magnetic element 43 and the blade portion 44 are disposed in the working space 5 in which the working fluid flows, wherein the blade portion 44 is located in the drainage space 53 and the pivoting portion 41 extends from the drainage space 53 Into the channel 52. Structurally, the pivot portion 41 is connected to the blade portion 44 and is positioned between the blade portion 44 and the base 3 in a direction perpendicular to the base. The blade portion 44 has a plurality of blades 441. The second magnetic element 43 is disposed on the blade portion 44 and/or the pivot portion 41. The water cooling head 1 shown in FIG. 1 is a second magnetic element 43 disposed on the pivot portion 41 and located in the channel 52 Happening. In addition, the first magnetic element 42 may be selected from silicon steel sheets or magnets, and the second magnetic element 43 may be selected from a magnet, but not limited to the above. Under the joint action of the circuit board 46, the first magnetic element 42 and the second magnetic element 43, the pivoting portion 41 and the blade portion 44 can be driven to rotate, thereby guiding the movement of the working fluid, especially absorbing heat from the working fluid The space 51 is guided upward to the drainage space 53 via the passage 52. In particular, in the creation of this case, the first magnetic element 42 is located in the blade portion 44 and the bottom in a direction perpendicular to the base The seat 3 is also located between the working fluid inlet 21 and the working fluid outlet 22.

其次，水冷頭1也可包含有一軸棒6以及一軸棒固定架7，讓樞轉部41與扇葉部44得以套設於軸棒6上，並以該軸棒6為旋轉中心而轉動，不過由於樞轉部41以及扇葉部44是在第一磁性元件42與第二磁性元件43之間的電磁感應作用下才產生轉動，並非藉由軸棒6來驅動，因此樞轉部41與軸棒6之間並不會同步轉動，申言之，在本實施例中，軸棒6最主要的功能是負責定位，讓套設在軸棒6上的樞轉部41與扇葉部44在轉動時不會發生偏移的情況。此外，軸棒6也因為有軸棒固定架7的輔助，因而不會產生偏移或脫離的情況，因此水冷頭1內的樞轉部41與扇葉部44可藉由軸棒6以及軸棒固定架7而穩固地持續轉動。 Secondly, the water cooling head 1 may also include a shaft rod 6 and a shaft rod fixing frame 7 to allow the pivoting portion 41 and the fan blade portion 44 to be sleeved on the shaft rod 6 and rotate around the shaft rod 6 as the center of rotation. However, because the pivoting portion 41 and the blade portion 44 are rotated only by the electromagnetic induction between the first magnetic element 42 and the second magnetic element 43, and are not driven by the shaft 6, the pivoting portion 41 and The shaft rods 6 will not rotate synchronously. In other words, in this embodiment, the main function of the shaft rod 6 is to be responsible for positioning, so that the pivot portion 41 and the fan blade portion 44 sleeved on the shaft rod 6 No deviation will occur during rotation. In addition, since the shaft rod 6 is assisted by the shaft rod fixing frame 7, there is no deviation or detachment. Therefore, the pivot portion 41 and the blade portion 44 in the water cooling head 1 can be passed through the shaft rod 6 and the shaft The rod holder 7 continues to rotate steadily.

再者，為了維持扇葉部44與樞轉部41的穩固轉動，因此軸棒6在設置上係從排水空間53經過通道52而向下延伸至吸熱空間內51，上下兩端分別固定在殼體2的凹槽24以及軸棒固定架7的凹槽71內。而軸棒固定架7則可如第1圖所示固定於底座3上，或是於其他的實施例中固定在底座的傳熱結構32上，或是從殼體2向下延伸的壁面上，本創作並不予以限制。 In addition, in order to maintain the stable rotation of the blade portion 44 and the pivot portion 41, the shaft 6 is installed to extend downward from the drainage space 53 through the channel 52 into the heat absorption space 51, and the upper and lower ends are fixed to the shell The groove 24 of the body 2 and the groove 71 of the shaft rod fixing frame 7. The shaft rod fixing frame 7 can be fixed on the base 3 as shown in FIG. 1, or in other embodiments on the heat transfer structure 32 of the base, or on the wall surface extending downward from the housing 2 , This creation is not restricted.

此外，為了延長扇葉44以及樞轉部41的使用壽命，減少與軸棒6之間的磨耗情況，因此，本實施例也可在水冷頭1內設置一個由耐磨耗材質所形成的軸套47，耐磨耗材質可以是複合塑膠(例如加入碳成分的塑膠)、聚苯硫醚(polyphenylene sulfide，縮寫為PPS)或是聚甲醛(polyoxymethylene，縮寫為POM)等。軸套47係設置並固定在樞轉部41內，而軸棒6則可套設在軸套47內。而如前所述，由於樞轉部41以及扇葉部44是在第一磁性元件42與第二磁性元件43之間的電磁感應作用下才產生轉動， 並非藉由軸棒6來驅動，因此固定在樞轉部41內的軸套47與軸棒6之間同樣也不會同步轉動。 In addition, in order to extend the service life of the fan blade 44 and the pivoting portion 41 and reduce the abrasion between the shaft 6 and the shaft 6, therefore, this embodiment may also be provided with a shaft formed of a wear-resistant material in the water cooling head 1 In sleeve 47, the wear-resistant material can be composite plastic (for example, plastic with carbon component added), polyphenylene sulfide (abbreviated as PPS) or polyoxymethylene (abbreviated as POM). The shaft sleeve 47 is arranged and fixed in the pivot portion 41, and the shaft rod 6 can be sleeved in the shaft sleeve 47. As mentioned above, because the pivoting portion 41 and the blade portion 44 are rotated by the electromagnetic induction between the first magnetic element 42 and the second magnetic element 43, It is not driven by the shaft 6, so the sleeve 47 fixed in the pivot 41 and the shaft 6 will not rotate synchronously.

請參考第1圖所示關於工作流體在水冷頭1內部的移動路徑8，在本創作所提供的水冷頭1中，當工作流體從工作流體入口21沿箭頭8A的方向進入作用空間5的吸熱空間51後，就可沿箭頭8B的方向沿路吸收傳熱結構32的熱能，之後就會在樞轉部41與扇葉部44的吸引與帶動下，沿著箭頭8C的方向經過通道52而向上傳遞，最終進入排水空間53後沿著箭頭8D的方向流往工作流體出口22而被排出。 Please refer to the movement path 8 of the working fluid inside the water cooling head 1 shown in FIG. 1. In the water cooling head 1 provided by this creation, when the working fluid enters the working space 5 from the working fluid inlet 21 in the direction of arrow 8A, the heat absorption After the space 51, the heat energy of the heat transfer structure 32 can be absorbed along the path in the direction of arrow 8B, and then, under the attraction and driving of the pivoting portion 41 and the blade portion 44, it can pass the channel 52 in the direction of arrow 8C and move upward After the transmission, it finally enters the drain space 53 and flows toward the working fluid outlet 22 in the direction of arrow 8D to be discharged.

請參閱第1圖與第2圖，位在排水空間53內的扇葉部44，在其相鄰兩扇葉441之間可界定出一腔室45，加上樞轉部41上形成有導引結構411，例如槽溝。因此當樞轉部41與扇葉部44因應第一磁性元件42與第二磁性元件43的共同作用而被驅動旋轉時，樞轉部41下方的工作流體會被吸引而沿著樞轉部41的導引結構411向上移動並進入數個腔室45中之至少一者。最後，工作流體會被旋轉而在工作流體出口22處被排出水冷頭1。 Please refer to FIG. 1 and FIG. 2, the blade portion 44 located in the drainage space 53 can define a cavity 45 between two adjacent blades 441, and the pivot portion 41 is formed with a guide The guiding structure 411 is, for example, a groove. Therefore, when the pivoting portion 41 and the blade portion 44 are driven to rotate in response to the cooperation of the first magnetic element 42 and the second magnetic element 43, the working fluid under the pivoting portion 41 will be attracted to move along the pivoting portion 41 The guiding structure 411 moves upward and enters at least one of the chambers 45.
