為讓本發明的上述特徵和優點能更明顯易懂，下文特舉實施例，並配合所附圖式作詳細說明如下。The above described features and advantages of the invention will be apparent from the following description.
現將詳細參考本發明之實施例，並在附圖中說明所述實施例之實例。另外，在圖式及實施方式中使用相同標號的元件/構件代表相同或類似部分。Reference will now be made in detail be made to the embodiments of the invention In addition, elements/members that use the same reference numerals in the drawings and the embodiments represent the same or similar parts.
圖1是依照本發明一實施例之伺服器系統的示意圖。請參閱圖1。伺服器系統100包括主電源110、待機電源130、風扇模組170、擴展卡模組180以及主機板模組300。主電源110用以提供伺服器系統100的主電壓P12V。待機電源130用以提供伺服器系統100的待機電壓 P12VSTBY。擴展卡模組(extension card module)180包括至少一擴展卡插槽(extension card slot)182，用以插接擴展卡。風扇模組170包括風扇170_1、…、170_n，其中風扇模組170的至少一風扇可用來對擴展卡模組180進行散熱。在本實施例中，假設風扇170_1可用來對擴展卡模組180進行散熱，但請注意，本案對擴展卡模組180進行散熱的風扇數量並不以此為限。1 is a schematic diagram of a server system in accordance with an embodiment of the present invention. Please refer to Figure 1. The server system 100 includes a main power source 110, a standby power source 130, a fan module 170, an expansion card module 180, and a motherboard module 300. The main power source 110 is used to provide the main voltage P12V of the server system 100. Standby power supply 130 is used to provide standby voltage of server system 100 P12VSTBY. The extension card module 180 includes at least one extension card slot 182 for plugging the expansion card. The fan module 170 includes fans 170_1, . . . , 170_n, wherein at least one fan of the fan module 170 can be used to dissipate the expansion card module 180. In this embodiment, it is assumed that the fan 170_1 can be used to dissipate heat from the expansion card module 180. However, it should be noted that the number of fans for dissipating the expansion card module 180 in this case is not limited thereto.
主機板模組300包括控制器160。控制器160用以檢測伺服器系統100在待機電壓作用狀態和主電壓作用狀態的切換。當伺服器系統100在主電壓作用狀態下時，此控制器160控制主電壓P12V作用於風扇模組170而使風扇170_1、…、170_n運行。The motherboard module 300 includes a controller 160. The controller 160 is configured to detect the switching of the servo system 100 in the standby voltage action state and the main voltage action state. When the servo system 100 is in the state of the main voltage, the controller 160 controls the main voltage P12V to act on the fan module 170 to operate the fans 170_1, . . . , 170_n.
控制器160檢測到伺服器系統100從主電壓作用狀態切換到待機電壓作用狀態時，先阻斷待機電壓P12VSTBY作用於風扇170_1，然後檢測擴展卡插槽182是否有擴展卡***。例如，當伺服器系統100在待機電壓作用狀態下，且檢測到有擴展卡接入擴展卡插槽182時，控制待機電壓P12VSTBY作用於風扇170_1而使風扇170_1對擴展卡模組180進行散熱，否則阻斷待機電壓P12VSTBY作用於風扇170_1以阻止風扇170_1的運行。When the controller 160 detects that the servo system 100 is switched from the main voltage action state to the standby voltage action state, it first blocks the standby voltage P12VSTBY from acting on the fan 170_1, and then detects whether the expansion card slot 182 has an expansion card insertion. For example, when the server system 100 is in the standby voltage state and detects that an expansion card is connected to the expansion card slot 182, the control standby voltage P12VSTBY acts on the fan 170_1 to cause the fan 170_1 to dissipate the expansion card module 180. Otherwise, the blocking standby voltage P12VSTBY acts on the fan 170_1 to block the operation of the fan 170_1.
此外，主機板模組300還可包括第一防倒灌單元120、第二防倒灌單元140以及切換單元150。在主電壓P12V供電情況下，控制器160可藉由控制切換單元150的運作，而將主電壓P12V供電給風扇模組170進行運轉。在主電 源110作用下時，待機電源130可以停止提供待機電壓P12VSTBY。In addition, the motherboard module 300 may further include a first anti-backflow unit 120, a second anti-backflow unit 140, and a switching unit 150. In the case of the main voltage P12V power supply, the controller 160 can supply the main voltage P12V to the fan module 170 for operation by controlling the operation of the switching unit 150. Main power When the source 110 is activated, the standby power source 130 can stop supplying the standby voltage P12VSTBY.
在待機電壓P12VSTBY作用下，控制器160可以根據檢測信號S1接收與否來進行切換單元150的運作控制。若接收到檢測信號S1，使切換單元150切換至待機電壓P12VSTBY，以待機電壓P12VSTBY供電給風扇170_1，以對擴展卡模組180進行散熱。若沒有接收到檢測信號S1則不對風扇170_1供電，亦即擴展卡插槽182上並未有擴展卡***，從而可以節省能源損耗。Under the action of the standby voltage P12VSTBY, the controller 160 can perform operation control of the switching unit 150 according to whether the detection signal S1 is received or not. If the detection signal S1 is received, the switching unit 150 is switched to the standby voltage P12VSTBY, and the standby voltage P12VSTBY is supplied to the fan 170_1 to dissipate heat from the expansion card module 180. If the detection signal S1 is not received, the fan 170_1 is not powered, that is, the expansion card slot 182 does not have an expansion card inserted, thereby saving energy loss.
再者，當伺服器系統100由待機電源130轉由主電源110供電後，由主電源110提供主電壓P12V至風扇模組170而使風扇170_1、…、170_n運行。Moreover, when the server system 100 is powered by the standby power source 130 from the main power source 110, the main power source 110 supplies the main voltage P12V to the fan module 170 to operate the fans 170_1, ..., 170_n.
由上述實施例的說明可以清楚得知，在待機電壓作用狀態下，若擴展卡未***擴展卡插槽182時不用對擴展卡模組180進行散熱，而在擴展卡***擴展卡插槽182時才需對擴展卡模組180進行散熱。It can be clearly seen from the description of the above embodiment that, in the standby voltage action state, if the expansion card is not inserted into the expansion card slot 182, the expansion card module 180 is not dissipated, and when the expansion card is inserted into the expansion card slot 182, The expansion card module 180 needs to be dissipated.
為了進一步說明伺服器系統，以下特舉另一實施例來對本發明進行說明。圖2是依照本發明另一實施例之伺服器系統的示意圖。請參閱圖2。伺服器系統200的組成構件類似於圖1的伺服器系統100，現僅針對部分構件進行較詳細說明。In order to further illustrate the server system, another embodiment will be described below in order to explain the present invention. 2 is a schematic diagram of a server system in accordance with another embodiment of the present invention. Please refer to Figure 2. The components of the server system 200 are similar to the server system 100 of Figure 1, and are now described in greater detail only for a portion of the components.
在本實施例中，切換單元150可以包括MOS開關152，但不以MOS開關為限。為了說明方便，將以PMOS來表示MOS開關152。In this embodiment, the switching unit 150 may include the MOS switch 152, but is not limited to the MOS switch. For convenience of explanation, the MOS switch 152 will be represented by a PMOS.
第一防倒灌單元120可以包括蕭特基二極體122，第二防倒灌單元140可以包括蕭特基二極體142。蕭特基二極體122和142是一種導通電壓降較低、允許高速切換的二極體，並且可以防止供電線路的逆向導通。蕭特基二極體122的陽極端電性連接至主電源110的輸出，蕭特基二極體122的陰極端電性連接至MOS開關152的源極。再者，蕭特基二極體142的陽極端電性連接至待機電源130的輸出，蕭特基二極體142的陰極端電性連接至MOS開關152的源極(S)。The first anti-backflow unit 120 may include a Schottky diode 122, and the second anti-backflow unit 140 may include a Schottky diode 142. The Schottky diodes 122 and 142 are diodes that have a low turn-on voltage drop, allow high speed switching, and prevent reverse conduction of the power supply line. The anode end of the Schottky diode 122 is electrically connected to the output of the main power source 110, and the cathode end of the Schottky diode 122 is electrically connected to the source of the MOS switch 152. Furthermore, the anode end of the Schottky diode 142 is electrically connected to the output of the standby power source 130, and the cathode end of the Schottky diode 142 is electrically connected to the source (S) of the MOS switch 152.
控制器160A可以為複雜可編程邏輯裝置(complex programmable logic device，CPLD)或是基板管理控制器(baseboard management controller，BMC)。另外，控制器160A可以電性連接主電源110與待機電源130.。The controller 160A can be a complex programmable logic device (CPLD) or a baseboard management controller (BMC). In addition, the controller 160A can electrically connect the main power source 110 and the standby power source 130.
控制器160A的實施態樣可以如下的幾種變化。第一種實施態樣，若控制器160A為主動控制主電源110與待機電源130時，控制器160A可據以控制主電源110與待機電源130的切換。第二種實施態樣，若控制器160A為非主動控制主電源110與待機電源130時，控制器160A可藉由檢測主電源110與待機電源130的電壓準位來得知目前電源供應狀態的切換。The implementation of controller 160A can vary in several ways as follows. In the first embodiment, if the controller 160A actively controls the main power source 110 and the standby power source 130, the controller 160A can control the switching between the main power source 110 and the standby power source 130. In the second embodiment, if the controller 160A is inactively controlling the main power source 110 and the standby power source 130, the controller 160A can detect the current power supply state switching by detecting the voltage levels of the main power source 110 and the standby power source 130. .
另外，擴展卡模組180可以配置成在有擴展卡***擴展卡插槽182時，自動發出高電平的檢測信號S1至控制器160。在待機電壓P12VSTBY作用狀態下，控制器160若接收到檢測信號S1則發出控制信號W1至MOS開關152 的閘極(G)以使MOS開關152導通，從而使待機電壓P12VSTBY能夠供電給風扇170_1(假設風扇170_1可用來對擴展卡模組180進行散熱)。在待機電壓P12VSTBY作用狀態下，控制器160若沒有接收到檢測信號S1則發出的控制信號W1將使MOS開關152不導通，從而不對風扇170_1供電。In addition, the expansion card module 180 can be configured to automatically issue a high level detection signal S1 to the controller 160 when an expansion card is inserted into the expansion card slot 182. In the active state of the standby voltage P12VSTBY, the controller 160 issues the control signal W1 to the MOS switch 152 if receiving the detection signal S1. The gate (G) is turned on to turn on the MOS switch 152, so that the standby voltage P12VSTBY can be supplied to the fan 170_1 (assuming that the fan 170_1 can be used to dissipate the expansion card module 180). In the active state of the standby voltage P12VSTBY, if the controller 160 does not receive the detection signal S1, the control signal W1 issued will cause the MOS switch 152 to be non-conducting, thereby not supplying power to the fan 170_1.
此外，主電源110可以是交流轉直流電源供應器，待機電源130可以是直流轉直流電源供應器。In addition, the main power source 110 may be an AC to DC power supply, and the standby power source 130 may be a DC to DC power supply.
在伺服器系統200中還可包括熔絲單元190，熔絲單元190耦接於MOS開關152的汲極(D)與風扇模組170之間。熔絲單元190可用來增進供電安全。A fuse unit 190 is also included in the server system 200. The fuse unit 190 is coupled between the drain (D) of the MOS switch 152 and the fan module 170. The fuse unit 190 can be used to enhance power supply safety.
圖3繪示為本發明一實施例之散熱控制方法的流程圖。請合併參閱圖1和圖3，本實施例的散熱控制方法適用於伺服器系統100而包括以下步驟。FIG. 3 is a flow chart of a heat dissipation control method according to an embodiment of the invention. Referring to FIG. 1 and FIG. 3 together, the heat dissipation control method of the present embodiment is applicable to the server system 100 and includes the following steps.
於步驟S301，伺服器系統100在待機電壓作用狀態。In step S301, the server system 100 is in a standby voltage action state.
接著，於步驟S303，控制器160檢測擴展卡插槽182是否有擴展卡***。若是，進入步驟S305，反之進入步驟S311。Next, in step S303, the controller 160 detects whether the expansion card slot 182 has an expansion card insertion. If yes, go to step S305, otherwise go to step S311.
於步驟S305，控制待機電壓P12VSTBY作用於風扇170_1(假設風扇170_1可用來對擴展卡模組180進行散熱)而使風扇170_1運行，以對擴展卡模組180進行散熱。接著，於步驟S307，伺服器系統100在主電壓作用狀態。然後，於步驟S309，切換至主電源110，控制主電壓P12V作用於風扇170_1而使風扇170_1繼續運行。In step S305, the control standby voltage P12VSTBY is applied to the fan 170_1 (assuming that the fan 170_1 can be used to dissipate the expansion card module 180) to operate the fan 170_1 to dissipate the expansion card module 180. Next, in step S307, the server system 100 is in the state of the main voltage. Then, in step S309, switching to the main power source 110, the control main voltage P12V acts on the fan 170_1 to cause the fan 170_1 to continue to operate.
於步驟S311，阻斷待機電壓P12VSTBY作用於風扇170_1以阻止風扇170_1的運行。接著，於步驟S313，伺服器系統100在主電壓作用狀態。然後，於步驟S315，切換至主電源110，控制主電壓P12V作用於風扇170_1而使風扇170_1運行。In step S311, the blocking standby voltage P12VSTBY acts on the fan 170_1 to block the operation of the fan 170_1. Next, in step S313, the server system 100 is in the state of the main voltage. Then, in step S315, switching to the main power source 110 controls the main voltage P12V to act on the fan 170_1 to cause the fan 170_1 to operate.
倘若在步驟S301之前伺服器系統100為主電壓作用狀態，當檢測到伺服器系統100從主電壓作用狀態切換到待機電壓作用狀態而進入步驟S301時，可以先阻斷待機電壓P12VSTBY作用於風扇170_1，然後才進行步驟S303來檢測擴展卡插槽182是否有擴展卡***。If the server system 100 is in the main voltage action state before the step S301, when it is detected that the server system 100 is switched from the main voltage action state to the standby voltage action state and proceeds to step S301, the standby voltage P12VSTBY may be blocked from acting on the fan 170_1. Then, step S303 is performed to detect whether the expansion card slot 182 has an expansion card insertion.
由上述實施例的說明可以清楚得知，在待機電壓作用狀態下，在擴展卡未***擴展卡插槽182時不用對擴展卡模組180進行散熱，而在擴展卡***擴展卡插槽182時才需對擴展卡模組180進行散熱，所以能夠解決擴展卡模組180的散熱問題，且本案可減少能源損耗而提高散熱效率。It can be clearly seen from the description of the above embodiment that in the standby voltage action state, when the expansion card is not inserted into the expansion card slot 182, the expansion card module 180 is not dissipated, and when the expansion card is inserted into the expansion card slot 182, The heat dissipation of the expansion card module 180 is required, so that the heat dissipation problem of the expansion card module 180 can be solved, and the energy loss can be reduced and the heat dissipation efficiency can be improved.
雖然本發明已以實施例揭露如上，然其並非用以限定本發明，任何所屬技術領域中具有通常知識者，在不脫離本發明的精神和範圍內，當可作些許更動與潤飾，故本發明的保護範圍當視後附的申請專利範圍所界定者為準。Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and those skilled in the art can make some changes and refinements without departing from the spirit and scope of the present invention.
