In the embodiment, the open computing server cabinet 10 further includes an expansion power module 100 (shown in fig. 3), and the expansion power module 100 is detachably inserted and electrically connected to the electrical bus 30 to supply power to the electrical bus 30. That is, the user can insert the expansion power module 100 into the electrical bus 30 of the open computing server cabinet 10 as required to supply power to the electrical bus 30 additionally.
Fig. 4 is a schematic diagram of another view of the expansion power module. FIG. 5 is a diagram of a housing concealing an expansion power module. Fig. 6 is a schematic view of another perspective of fig. 5. FIG. 7 is a schematic diagram of an expansion power module plugged into an electrical bus. Referring to fig. 4 to 7, in detail, in the embodiment, the expansion power module 100 includes a circuit board 110, a second controller 120, a second connector 130, a storage device 140, a converter 150, and a housing 160. In the present embodiment, the second controller 120, the storage device 140 and the converter 150 are located on one side of the circuit board 110, and the second connector 130 is located on the other side of the circuit board 110 and corresponds to the electrical bus 30. The cover 160 covers a portion of the circuit board 110, the second controller 120, the power storage device 140, and the converter 150, and exposes the second connector 130.
In the present embodiment, the second connector 130, the power storage device 140 and the converter 150 are electrically connected to the second controller 120, respectively. The storage device 140 may be a battery or a super capacitor, which can store electric energy. The expansion power module 100 of the present embodiment is detachably inserted and electrically connected to the electrical bus 30 through the through hole 52 (labeled in fig. 2) of the protection shell 50 by the second connector 130. When the second connector 130 of the augmented power module 100 is docked to the electrical bus 30, the second controller 120 may instruct the transfer of electrical energy of the electrical storage device 140 to the electrical bus 30 to power the electrical bus 30. In this way, in addition to the main power module 40 inserted into one of the shelves 26 for supplying power to the electrical bus 30, the open computing server 10 of the embodiment further includes the expansion power module 100 detachably inserted into the electrical bus 30 for supplying power to the electrical bus 30, so as to satisfy different power requirements.
In addition, referring to fig. 2, fig. 3 and fig. 7, in the embodiment, the open computing server cabinet 10 (shown in fig. 1) includes a protective shell 50 covering the rear side of the electrical bus 30. As can be seen from fig. 2, the protective shell 50 includes a through opening 52 and a first fixing portion 54 beside the through opening 52. The through opening 52 is used for the expansion power module 100 to be plugged into the electrical bus 30 from the rear side 24 of the chassis 20 through the through opening 52. Of course, in other embodiments, the protection casing 50 may be omitted, and the expansion power module 100 may be directly plugged into the electrical bus 30. It should be noted that fig. 1 schematically shows the number and the positional arrangement of the through holes 52, and the present invention is not limited thereto.
As shown in fig. 2, in the present embodiment, two first fixing portions 54 are disposed on the upper and lower sides of each through hole 52, and the first fixing portions 54 are, for example, screw holes or through holes, but the type of the first fixing portions 54 is not limited thereto. As shown in fig. 3, the housing 160 includes two second fixing portions 162 corresponding to the first fixing portions 54, and the second fixing portions 162 are, for example, through holes, but the type of the second fixing portions 162 is not limited thereto.
As shown in fig. 7, when the expansion power module 100 is to be fixed on the protection casing 50, the expansion power module can be fixed by the fixing element 170 passing through the second fixing portion 162 (shown in fig. 3) of the outer cover 160 and being locked to the first fixing portion 54 (shown in fig. 2) of the protection casing 50, and of course, the types of the first fixing portion 54 of the protection casing 50, the second fixing portion 162 of the outer cover 160 and the fixing element 170 are not limited thereto.
Fig. 8 is a cross-sectional schematic view of the relative relationship of the electrical bus, first connector and second connector. Referring to fig. 8, the main power module 40 includes a first connector 42 corresponding to the electrical bus 30, and the main power module 40 is inserted through the first connector 42 and electrically connected to the electrical bus 30. In this embodiment, the first connector 42 of the main power supply module 40 and the second connector 130 of the expansion power supply module 100 may be the same connector, but the first connector 42 of the main power supply module 40 and the second connector 130 of the expansion power supply module 100 may be different connectors as long as they can respectively correspond to the electrical bus 30. In addition, fig. 8 only schematically illustrates one of the electrical buses 30 and the first connector 42 and the second connector 130 inserted into the electrical bus 30, and the electrical buses 30 of the other strips may have the same connection relationship, which is not repeated.
In the present embodiment, since the first connector 42 of the main power supply module 40 and the second connector 130 of the expansion power supply module 100 are not in the same plane, the first connector 42 is shown by a dotted line in fig. 8, but the relative relationship between the first connector 42 and the second connector 130 of the expansion power supply module 100 can be known from fig. 8. More specifically, in the present embodiment, since main power supply module 40 enters and exits chassis 20 from front side 22 and is plugged into the front side of electrical bus 30, augmented power supply module 100 is plugged into the front side of electrical bus 30 from rear side 24 of chassis 20. Accordingly, the first connector 42 of the main power supply module 40 and the second connector 130 of the extended power supply module 100 are plugged to opposite ends of the electrical bus 30, respectively, as shown in fig. 8. Furthermore, since the depth of the electrical bus 30 is greater than the sum of the depths of the first connector 42 of the main power supply module 40 and the second connector 130 of the extended power supply module 100, the first connector 42 of the main power supply module 40 and the second connector 130 of the extended power supply module 100 do not interfere with each other even if they are located on the same plane.
Of course, in other embodiments, if the first connector 42 of the main power source module 40 and the second connector 130 of the expansion power source module 100 are staggered in the height direction, the depth of the electrical bus 30 may be smaller than the sum of the depths of the first connector 42 of the main power source module 40 and the second connector 130 of the expansion power source module 100, as long as the depth of the electrical bus 30 is greater than or equal to the depth of the first connector 42 of the main power source module 40 and the depth of the second connector 130 of the expansion power source module 100, respectively.
It should be noted that, in the present embodiment, when the expansion power module 100 is plugged into the electrical bus 30, the expansion power module 100 may be connected to the main power module 40 in series, that is, the main power module 40 and the expansion power module 100 are connected with different electrodes. In this state, the main power module 40 and the extended power module 100 can provide a larger amount of current to the electrical bus 30, and can provide a larger start current. If the power demand of the servers in the open computing server rack 10 is large, the expansion power module 100 can provide enough power together with the main power module 40 through such a connection manner.
Of course, the expansion power supply module 100 may be connected to the main power supply module 40 in parallel, that is, the main power supply module 40 and the expansion power supply module 100 are connected by the same electrode. In this state, when the main power module 40 cannot supply power due to, for example, a power failure of the utility power, the expansion power module 100 can also supply power to the power bus 30, thereby achieving the effect of a standby power. In the present embodiment, the converter 150 (shown in fig. 6) of the expansion power module 100 can convert the positive and negative poles of the second connector 130 of the expansion power module 100, so that the expansion power module 100 can be selectively connected in series or in parallel with the main power module 40.
In addition, in the embodiment, the main power module 40 includes a first controller 46 (shown in fig. 1), and the second controller 120 of the extended power module 100 is connected to the first controller 46 by a signal to obtain the power information of the main power module 40. For example, when the amount of power supplied to the electrical bus 30 by the main power module 40 is sufficient, the second controller 120 of the extended power module 100 can obtain the information about the amount of power supplied by the main power module 40 via the first controller 46, and at this time, the extended power module 100 plugged in the electrical bus 30 can turn off the power supply function, and even can be switched to a charging mode to obtain power from the electrical bus 30. When the expansion power module 100 receives that the amount of power supplied to the electrical bus 30 by the main power module 40 is insufficient, the expansion power module 100 inserted in the electrical bus 30 may turn on the power supply mode or switch from the charging mode to the power supply mode to supply power to the electrical bus 30. Therefore, the user can keep the expansion power supply module 100 on the electrical bus 30, and the expansion power supply module 100 will automatically charge or discharge according to the power supply status of the main power supply module 40, thereby further increasing the convenience of use.
In summary, the open operation server cabinet of the present invention includes, in addition to the main power module inserted into one of the shelves for supplying power to the electrical bus, an expansion power module detachably inserted into the electrical bus for supplying power to the electrical bus. That is, when the power requirement of the open operation server cabinet is a general requirement, the user can detach the expansion power module. When the open operation server cabinet has a large power demand, a user can automatically plug in one or more expansion power supply modules to the electric bus to expand the electric quantity of the electric bus, so that even if a plurality of servers with large electric quantity demands are plugged in the open operation server cabinet, the matching of the main power supply module and the expansion power supply modules can also meet the power demand.
Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
