Therefore, the directional terms used in the embodiments are used to illustrate and are not used to limit the present invention.

請一併參閱第2、3、4、5圖，其中第2圖表示本發明一實施例之電路模組200的立體圖，第3圖表示第2圖中之電路模組200的另一視角立體圖，第4圖表示第2、3圖中之鰭片單元220的立體圖，第5圖表示第2、3圖中之鰭片單元220的另一視角立體圖。Please refer to Figures 2, 3, 4 and 5 together, wherein Figure 2 shows a three-dimensional view of a circuit module 200 of an embodiment of the present invention, Figure 3 shows a three-dimensional view of the circuit module 200 in Figure 2 from another viewing angle, Figure 4 shows a three-dimensional view of the fin unit 220 in Figures 2 and 3, and Figure 5 shows a three-dimensional view of the fin unit 220 in Figures 2 and 3 from another viewing angle.

如第2、3、4、5圖所示，本發明一實施例之電路模組200例如為設置在桌上型電腦或其他電子裝置內部的顯示卡模組，其主要包含有一電路單元210、鰭片單元220、一第一風扇230以及一第二風扇240。As shown in FIGS. 2 , 3 , 4 , and 5 , a circuit module 200 according to an embodiment of the present invention is, for example, a display card module installed in a desktop computer or other electronic devices, and mainly includes a circuit unit 210 , a fin unit 220 , a first fan 230 , and a second fan 240 .

前述鰭片單元220包含有一第一平板結構2201、一第二平板結構2202以及複數個平行排列的散熱鰭片2203，其中在相鄰的前述散熱鰭片2203之間形成有氣體通道2204。The fin unit 220 includes a first flat plate structure 2201 , a second flat plate structure 2202 , and a plurality of heat dissipation fins 2203 arranged in parallel, wherein a gas channel 2204 is formed between adjacent heat dissipation fins 2203 .

需特別說明的是，前述鰭片單元220可含有高導熱係數之材質，其中第一平板結構2201以及第二平板結構2202係垂直於散熱鰭片2203，並且分別設置在散熱鰭片2203的底側以及頂側，而散熱鰭片2203則是平行於一垂直方向(Z軸方向)，並且連接前述第一平板結構2201以及第二平板結構2202。It should be particularly noted that the aforementioned fin unit 220 may contain a material with a high thermal conductivity coefficient, wherein the first flat plate structure 2201 and the second flat plate structure 2202 are perpendicular to the heat sink fin 2203 and are respectively arranged on the bottom and top sides of the heat sink fin 2203, and the heat sink fin 2203 is parallel to a vertical direction (Z-axis direction) and connects the aforementioned first flat plate structure 2201 and the second flat plate structure 2202.

舉例而言，前述鰭片單元220可含有銅或鋁等金屬材質，並可透過一體成形的方式製作，但不以本實施例所揭露者為限。For example, the fin unit 220 may contain metal materials such as copper or aluminum, and may be manufactured by an integral forming method, but is not limited to that disclosed in this embodiment.

此外，從第2、3、4、5圖中可以看出，本實施例之鰭片單元220具有一長條形結構，其中鰭片單元220的長軸方向平行於X軸，且每一散熱鰭片2203皆與鰭片單元220的長軸方向(X軸方向)相互垂直。In addition, it can be seen from FIGS. 2, 3, 4 and 5 that the fin unit 220 of this embodiment has a long strip structure, wherein the long axis direction of the fin unit 220 is parallel to the X axis, and each heat dissipation fin 2203 is perpendicular to the long axis direction (X axis direction) of the fin unit 220.

在組裝過程中，可將板狀之電路單元210(例如印刷電路板)固定在鰭片單元220的底側，其中電路單元210係垂直於Z軸，且平行於XY平面。舉例而言，前述電路單元210可透過螺絲鎖附在鰭片單元220底側的第一平板結構2201上，組裝時可將導熱膏(thermal paste)施加於電路單元210上之一特定積體電路元件(例如GPU)的表面，並使其與第一平板結構2201接觸，從而能夠使該特定積體電路元件所產生的熱迅速地傳導到鰭片單元220的散熱鰭片2203。During the assembly process, a plate-shaped circuit unit 210 (e.g., a printed circuit board) can be fixed to the bottom side of the fin unit 220, wherein the circuit unit 210 is perpendicular to the Z axis and parallel to the XY plane. For example, the circuit unit 210 can be screwed onto the first flat plate structure 2201 on the bottom side of the fin unit 220. During assembly, thermal paste can be applied to the surface of a specific integrated circuit element (e.g., a GPU) on the circuit unit 210 and brought into contact with the first flat plate structure 2201, so that the heat generated by the specific integrated circuit element can be quickly transferred to the heat dissipation fin 2203 of the fin unit 220.

另一方面，從第2、3圖中可以看出第一風扇230以及第二風扇240係沿著鰭片單元220的長軸方向(X軸方向)排列，且其係固定在鰭片單元220之第一側S1，藉以和散熱鰭片2203之間的氣體通道2204相連通。On the other hand, it can be seen from FIGS. 2 and 3 that the first fan 230 and the second fan 240 are arranged along the long axis direction (X axis direction) of the fin unit 220 and are fixed to the first side S1 of the fin unit 220 to communicate with the gas channel 2204 between the heat dissipation fins 2203 .

在本實施例中，可利用第一風扇230以及第二風扇240產生一氣流，並驅使空氣從鰭片單元220之第二側S2進入到散熱鰭片2203之間的氣體通道2204內(如第2圖中之箭頭A3方向所示)，且空氣在流過散熱鰭片2203之間的氣體通道2204後可經由鰭片單元220的第一側S1排出到外界(如第2圖中之箭頭A4方向所示)，從而能夠達成快速降溫之目的，其中前述第二側S2相反於第一側S1。In this embodiment, the first fan 230 and the second fan 240 can be used to generate an airflow and drive the air from the second side S2 of the fin unit 220 into the gas channel 2204 between the heat dissipation fins 2203 (as shown in the direction of arrow A3 in FIG. 2 ), and after the air flows through the gas channel 2204 between the heat dissipation fins 2203, it can be discharged to the outside through the first side S1 of the fin unit 220 (as shown in the direction of arrow A4 in FIG. 2 ), thereby achieving the purpose of rapid cooling, wherein the aforementioned second side S2 is opposite to the first side S1.

又，從第3圖中可以看出，第一風扇230以及第二風扇240分別具有相互平行之一第一中心軸C1以及一第二中心軸C2，其中前述第一中心軸C1以及第二中心軸C2係平行於一水平方向(Y軸方向)，意即前述第一中心軸C1以及第二中心軸C2垂直於鰭片單元220的長軸方向(X軸方向)以及Z軸方向，並且平行於電路單元210以及XY平面。Furthermore, it can be seen from FIG. 3 that the first fan 230 and the second fan 240 respectively have a first center axis C1 and a second center axis C2 which are parallel to each other, wherein the first center axis C1 and the second center axis C2 are parallel to a horizontal direction (Y-axis direction), that is, the first center axis C1 and the second center axis C2 are perpendicular to the long axis direction (X-axis direction) and the Z-axis direction of the fin unit 220, and are parallel to the circuit unit 210 and the XY plane.

應了解的是，由於本實施例中的第一風扇230以及第二風扇240係設置在鰭片單元220之第一側S1，且正對於散熱鰭片2203之間的氣體通道2204，因此第一風扇230以及第二風扇240所產生的氣流可沿水平方向(Y軸方向)通過鰭片單元220而將熱迅速地排出電路模組200；此外，由於前述第一風扇230以及第二風扇240並非直接設置在鰭片單元220頂側的第二平板結構2202上，如此一來不僅能夠有效地縮減電路模組200在垂直方向(Z軸方向)上的尺寸，以達成機構小型化之目的，同時也可以在第二平板結構2202的表面設置儀表或顯示面板，以作為其他功能使用。It should be understood that, since the first fan 230 and the second fan 240 in this embodiment are disposed on the first side S1 of the fin unit 220 and are directly opposite to the air channel 2204 between the heat dissipation fins 2203, the airflow generated by the first fan 230 and the second fan 240 can pass through the fin unit 220 in the horizontal direction (Y-axis direction) to quickly discharge the heat from the circuit module 200; in addition, Since the first fan 230 and the second fan 240 are not directly disposed on the second flat plate structure 2202 on the top side of the fin unit 220, not only can the size of the circuit module 200 in the vertical direction (Z-axis direction) be effectively reduced to achieve the purpose of miniaturization of the structure, but also an instrument or display panel can be disposed on the surface of the second flat plate structure 2202 for other functions.

接著請參閱第6圖，其中第6圖表示本發明另一實施例之電路模組200的立體圖。Please refer to FIG. 6 , which is a three-dimensional diagram of a circuit module 200 according to another embodiment of the present invention.

如第6圖所示，本實施例與第2圖中所示之電路模組200的主要不同處在於：第6圖中之鰭片單元220的第二平板結構2202表面上設有一指示燈單元L及/或一顯示單元T，其中前述顯示單元T(例如LCD或七段顯示器)可用以顯示電路單元210上之一溫度感測器(未圖示)所感測到的溫度，且當該溫度高於一預設值時，更可藉由點亮指示燈單元L上的燈號(例如紅燈)，以作為提醒使用者或操作者之一警告訊號。As shown in FIG. 6 , the main difference between this embodiment and the circuit module 200 shown in FIG. 2 is that an indicator light unit L and/or a display unit T is provided on the surface of the second flat plate structure 2202 of the fin unit 220 in FIG. 6 , wherein the aforementioned display unit T (such as an LCD or a seven-segment display) can be used to display the temperature sensed by a temperature sensor (not shown) on the circuit unit 210, and when the temperature is higher than a preset value, the light on the indicator light unit L (such as a red light) can be turned on as a warning signal to remind the user or operator.

綜上所述，本發明主要係提供一種電路模組200，其中第一風扇230以及第二風扇240(或者也可僅設置第一風扇230)可產生一氣流沿水平方向(Y軸方向)通過鰭片單元220，從而能夠將鰭片單元220底側之電路單元210所產生的熱迅速地排出電路模組200，其中前述電路單元210係平行於水平方向(Y軸方向)以及鰭片單元220的長軸方向(X軸方向)，並且垂直於Z軸。In summary, the present invention mainly provides a circuit module 200, wherein the first fan 230 and the second fan 240 (or only the first fan 230) can generate an airflow through the fin unit 220 along the horizontal direction (Y-axis direction), so as to quickly discharge the heat generated by the circuit unit 210 on the bottom side of the fin unit 220 from the circuit module 200, wherein the aforementioned circuit unit 210 is parallel to the horizontal direction (Y-axis direction) and the long axis direction (X-axis direction) of the fin unit 220, and perpendicular to the Z-axis.

應了解的是，由於前述第一風扇230以及第二風扇240並非直接設置在鰭片單元220頂側的第二平板結構2202上，如此一來不僅能夠有效地縮減電路模組200在垂直方向(Z軸方向)上的尺寸，以達成機構小型化之目的，同時也可以在第二平板結構2202的表面設置指示燈單元L及/或顯示單元T (如第6圖所示)，從而能大幅提升使用上的便利性。It should be understood that since the aforementioned first fan 230 and the second fan 240 are not directly disposed on the second flat plate structure 2202 on the top side of the fin unit 220, this can not only effectively reduce the size of the circuit module 200 in the vertical direction (Z-axis direction) to achieve the purpose of miniaturization of the structure, but also an indicator light unit L and/or a display unit T (as shown in FIG. 6 ) can be disposed on the surface of the second flat plate structure 2202, thereby greatly improving the convenience of use.
