[0060] The following disclosure provides numerous different implementations, or examples, for carrying out various features of the provided object. Specific examples of elements and arrangements are described below to simplify the subject matter. Of course, these examples are merely illustrative and are not intended to be limiting. Furthermore, element symbols and / or letters may be repeated in various examples. This repetition is for simplicity and clarity and does not, in itself, specify a relationship between the various implementations and / or configurations discussed.
[0061] Spatial relative terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for descriptive purposes to describe the relationship between one element or feature and another, as shown in the accompanying drawings. Spatial relative terms are intended to cover different orientations of the apparatus in use or operation other than those shown in the accompanying drawings. The apparatus may be oriented in other ways (rotated 90 degrees or otherwise), and the spatial relative descriptors used herein shall be interpreted accordingly.
[0062] Figure 1 A perspective view of a multi-functional cabinet 100 according to an embodiment of the present disclosure is shown. Figure 2 Show Figure 1 A close-up view of the first inner door 140. See also... Figure 1 and Figure 2 The multi-functional cabinet 100 includes a support frame 110, an outer door 120, an electrical control box 130, and a first inner door 140. The outer door 120 is pivotally connected to the edge (e.g., the left edge) of the support frame 110. The electrical control box 130 is connected to the support frame 110 and includes a main switch 131. The first inner door 140 is pivotally connected to the edge (e.g., the left edge) of the electrical control box 130. The main switch 131 is at least partially exposed from the first inner door 140. In this embodiment, the first inner door 140 has an opening 142, and the position of the opening 142 corresponds to the position of the main switch 131, such that the main switch 131 is at least partially exposed from the first inner door 140. Because the first inner door 140 exposes the main switch 131, the operator can safely and easily start and stop the power supply.
[0063] In some implementations, the multi-functional cabinet 100 may be used in a data center cooling system (such as a water-cooling system), but is not limited thereto. The multi-functional cabinet 100 also includes a display device 180. The display device 180 is located on the outer door 120. When the outer door 120 is closed, the display device 180 faces outwards and displays the system operating status. Furthermore, the outer door 120 has a locking mechanism 122. When the outer door 120 is closed, it is secured by the locking mechanism 122. When the outer door 120 is opened, the display device 180 may issue a warning.
[0064] In some implementations, the outer door 120 can only be opened by operators, but the first inner door 140 cannot be opened by operators and is only openable by technicians. This configuration prevents unauthorized personnel from opening the outer door 120, avoiding entry of personnel other than operators and technicians (such as visitors) into the multi-functional cabinet 100, which could cause malfunctions in the system and machinery. In this implementation, the first inner door 140 also includes a keyhole 144, which can be unlocked with a key to open the first inner door 140, allowing only technicians with the key to open it, achieving a layered personnel management effect.
[0065] In addition to the functions of anti-theft and anti-accidental touch, the outer door 120 and the first inner door 140 expose the main switch 131 on the outermost layer of the electrical control box 130 (such as the electrical panel), so that the operation of the entire system (such as power supply and disconnection) can be directly controlled after the outer door 120 is opened.
[0066] In this embodiment, the multi-functional cabinet 100 also includes a rear door 190 and at least one pump 170. The rear door 190 is pivotally connected to the support frame 110 on the side opposite to the outer door 120 (e.g., the rear side), and the space inside the rear door 190 can accommodate cooling pipes. The pump 170 is located on the support frame 110 and below the electrical control box 130. The pump 170 is electrically connected to the electrical control box 130 and fluidly connected to the cooling pipes. When the water circuit malfunctions, the operator can open the rear door 190 to check the operating status of the water circuit.
[0067] Figure 3 Show Figure 2 A partially enlarged view of the main switch 131. See also... Figure 2 and Figure 3The main switch 131 includes a switching element 132 and a handle 133. One end of the handle 133 is pivotally connected above the switching element 132, and the handle 133 extends below the switching element 132, configured to either block or allow the switching element 132 to move horizontally. Furthermore, the switching element 132 and the handle 133 protrude from the opening 142 of the first inner door 140. Additionally, a lock cylinder 150 can be selectively suspended on the handle 133 of the main switch 131, and the lock cylinder 150 is located outside the first inner door 140. When the main switch 131 trips, the operator can first unlock the lock cylinder 150, then pull the handle 133 from bottom to top, and then pull the switching element 132 to the right and then to the left to restore power. In addition to its anti-theft function, the lock cylinder 150 and the keyhole 144 of the first inner door 140 also prevent the operator from touching other electronic components (such as live and inductive components) in the first inner door 140. After opening the outer door 120, operators can control the entire system's operation via the main switch 131, such as starting and shutting down the system. The water-cooling system is one of the main pieces of equipment in the data center, used to cool the high temperatures generated by the power system. Therefore, the conditions for accidental activation must be minimized; hence, a lock 150 is installed to prevent manual operation of the main switch 131. The cooling system must always be in operation. This prevents the possibility of significant equipment damage due to accidental activation.
[0068] Figure 4 Show Figure 1 A 3D view of the first inner door 140 of the multi-functional cabinet 100 when it is open. Also see... Figure 1 and Figure 4 The multi-functional cabinet 100 also includes a second inner door 160. The electrical control box 130 includes at least one control unit 134, at least one pump switch 135, and at least one sensing element interface 136. The number of control units 134, pump switches 135, and sensing element interfaces 136 is not intended to limit this disclosure. The control unit 134 may include a variable-frequency drive (VFD). The pump switch 135 is electrically connected to the pump 170. When the first inner door 140 is closed (e.g....), Figure 1 As shown), the first inner door 140 covers the control unit 134, pump switch 135, and sensing element interface 136. The second inner door 160 is pivotally connected to the edge (e.g., the left edge) of the control box 130. When the first inner door 140 is open and the second inner door 160 is closed (e.g., ...), the second inner door 160 is closed. Figure 4 As shown, the main switch 131, control unit 134, pump switch 135 and sensing element interface 136 are at least partially exposed from the second inner door 160.
[0069] Figure 5 Show Figure 4 A partially enlarged view of the electrical control box 130. See also... Figure 4 and Figure 5The second inner door 160 has notches 162 and 164 at its two corners, with notch 162 corresponding to the position of the control unit 134 and notch 164 corresponding to the position of the sensing element interface 136. This design allows the control unit 134 to be exposed through notch 162 and the sensing element interface 136 through notch 164. Technicians can observe and maintain the control unit 134 and the sensing element interface 136 through notches 162 and 164 when the second inner door 160 is closed. Furthermore, the second inner door 160 has openings 166 and 168, with opening 166 corresponding to the position of the main switch 131 and opening 168 corresponding to the position of the pump switch 135. Through this design, the second inner door 160 exposes the control unit 134, the sensing element interface 136, the main switch 131, and the pump switch 135.
[0070] When the second inner door 160 is closed, technicians (such as testing personnel) can open and close the switches of various circuit components, for example, controlling the operation of the corresponding pump 170 via pump switch 135. Since pump 170 is a consumable component, pump switches 135 can be individually disconnected without opening the second inner door 160, allowing technicians to perform maintenance and component replacement on pump 170 without shutting down the system. For example, technicians can detect sensor malfunctions through the exposed sensor interface 136 and perform repairs and replacements. The second inner door 160 allows technicians (such as testing personnel) to confirm the condition of critical components (such as pump 170) and to confirm the opening and closing of the circuits of each critical component, thereby controlling the operation of each critical component (such as each pump 170).
[0071] Although the second inner door 160 of the multi-functional cabinet 100 exposes switches and components of important control circuits, the layout of the power lines is shielded. The closed second inner door 160 prevents non-electrical maintenance personnel from accessing the electronic components inside the second inner door 160.
[0072] Figure 6 Show Figure 5 A 3D view of the second inner door 160 of the multi-functional cabinet 100 when it is open. Figure 7 Show Figure 6 A partially enlarged view of the electrical control box 130. See also... Figure 6 and Figure 7 The first inner door 140 is located between the outer door 120 and the second inner door 160. The height of the outer door 120 is greater than the height of both the first inner door 140 and the second inner door 160, and the area of the first inner door 140 is greater than the area of the second inner door 160. The electrical control box 130 includes multiple electrical components 137, which can be covered by the closed second inner door 160 (e.g., ...). Figure 5(As shown). In some embodiments, electrical component 137 may include a switch 138 for a control circuit and a power line 139, but this is not intended to limit the scope of this disclosure.
[0073] When the second inner door 160 is opened, the main power must be shut off via the main switch 131, and maintenance must be performed by electrical repair personnel for comprehensive maintenance and replacement. For example, the second inner door 160 is designed for initial equipment installation or for maintenance of various electrical components in the event of a serious system malfunction. Only after the second inner door 160 is opened can electrical repair personnel replace protective components (such as the control circuit switch 138) and control components (such as the control unit 134).
[0074] In summary, the multi-functional cabinet 100 combines maintenance and control functions. Since the multi-functional cabinet 100 includes an outer door 120, an electrical control box 130, a first inner door 140, and a second inner door 160, and the first inner door 140 is located between the outer door 120 and the second inner door 160, therefore the first inner door 140 (see...) Figure 1 The control unit 134, pump switch 135, and sensing element interface 136 of the electrical control box 130 can be covered. The main switch 131 can be at least partially exposed from the first inner door 140, and the second inner door 160 (see...) Figure 4 The second inner door 160 covers the electrical components 137, and the main switch 131, control unit 134, pump switch 135, and sensing element interface 136 are at least partially exposed from the second inner door 160. In this way, the multi-functional cabinet 100 has anti-theft and anti-accidental touch functions, enabling hierarchical personnel control. For example, the outer door 120 prevents unauthorized personnel from opening and closing the door, while the first inner door 140 allows operators to safely and easily start and stop the power supply using the main switch 131. Furthermore, the first inner door 140 prevents operators from accessing electronic components that should only be accessed by technicians (such as testing personnel), and the second inner door 160 prevents non-electrical maintenance personnel from touching the electrical components 137.
