[0048] In one embodiment of the present application, Figure 1 As shown, the array cabinet includes a frame 100, a DC input unit 200, a DC output unit 300, a cooling liquid distribution unit 400, and a liquid cooling plate assembly 500. Each of the above components will be further described in detail below.
[0049] like Figure 2 As shown, the display cabinet includes a frame 100 and a door panel 110 and a panel 120 installed on the frame 100. The frame 100 is welded as a whole, and the door panels 110 are installed on the front and back of the frame 100. Preferably, the door panels 110 adopt a double-door structure with a left front door and a right front door. A monitoring panel, a liquid crystal display module, indicator lights, a file bag, etc. are installed on the door panel 110 to monitor and display various operating states of the product. Among them, inspection record documents can be placed in the file bag. After the monitoring panel and the liquid crystal display module are installed, the monitoring cover and the display cover are detachably installed by fasteners such as screws to cover and protect the monitoring panel and the liquid crystal display module.
[0050] like Figure 2 As shown, the front of the frame 100 is covered by a panel 120, so that the live parts of the product are not exposed, meeting safety regulations. The panel 120 has an opening 140 at the operation interface of the circuit breaker 320 for avoidance. When maintaining the product, just remove the screws of the panel 120 to perform maintenance.
[0051] like Figure 1As shown, the DC input unit 200 is arranged at the top of the frame 100, and mainly includes an incoming line bar 210, a fuse 220, a partition 230, and a DC input cable 240. The incoming line bar 210 is installed at the top of the frame 100. In one embodiment of the present application, in order to cope with the dual power input of the server, the terminal cabinet is in a double busbar form, that is, two DC input cables 240 are arranged side by side. The input end of the DC input cable 240 is connected to the incoming line bar 210 at the top of the cabinet, and is connected to the DC output unit 300 after being output through the fuse 220. That is, one end of the fuse 220 is connected to the incoming line bar 210, and the other end is connected to the DC output unit 300. The partition 230 is installed between two adjacent fuses 220 to ensure the safety distance between the positive and negative poles.
[0052] The DC output unit 300 and the liquid cooling plate assembly 500 are arranged in the middle of the frame 100. The DC output unit 300 includes a busbar assembly 310, a circuit breaker 320, and an output cable 330. In one embodiment of the present application, corresponding to the two DC input cables 240, the busbar assembly 310 also has two rows. The two busbar assemblies 310 are arranged vertically from top to bottom, and the circuit breakers 320 are arranged on both sides of the busbar assembly 310 in a fishbone pattern. The busbar assembly 310 and the input end of the circuit breaker 320 are fixed together by fasteners such as rivet studs. The circuit breaker 320 is installed vertically on the overlapping surface of the busbar assembly 310 in the depth direction, that is, the circuit breaker 320 extends in a direction perpendicular to the length direction of the liquid cooling plate 510.
[0053] The output cable 330 is fixedly connected to the output end of the circuit breaker 320 and is connected to each server rack through the output cable 330. The output cable 330 is laid on the output side of the circuit breaker 320. Specifically, Figure 3 As shown, a wire trough 130 is provided in the frame 100, and the output cables 330 are laid in the wire trough 130. The output cables 330 are laid along the wire trough 130, which is beautiful and neat.
[0054] like Figure 1 and Figure 3As shown, the liquid cooling plate assembly 500 mainly includes a liquid cooling plate 510, a quick-connect connector 520, a secondary liquid inlet pipe 530, and a secondary liquid outlet pipe 540. The liquid cooling plate 510 is used to contain coolant and is generally in the shape of an elongated plate, extending along the length of the busbar assembly 310. The liquid cooling plate 510 is arranged adjacent to the busbar assembly 310. A heat dissipation substrate is provided on the back of the circuit breaker 320. The heat dissipation substrate is tightly attached to the liquid cooling plate 510, and heat is removed by contact conduction through the liquid cooling plate 510. One end of the quick-connect connector 520 is fixedly mounted on the bottom of the liquid cooling plate 510, and the other end is used to detachably connect to one end of the secondary liquid inlet pipe 530 and the secondary liquid outlet pipe 540. The other ends of the secondary liquid inlet pipe 530 and the secondary liquid outlet pipe 540 are connected to the coolant distribution unit 400.
[0055] The coolant distribution unit 400 (CDU) is used to cool, distribute and regulate the coolant in the system. The coolant distribution unit 400 is arranged at the bottom of the frame 100 and includes a heat exchanger, a liquid pump and a primary side interface 410 for connecting to a cooling source.
[0056] The liquid pump inside the cooling liquid distribution unit 400 drives the secondary cooling liquid to circulate continuously. The cooling plate 510 is in close contact with the circuit breaker 320. The high temperature generated by the circuit breaker 320 is transferred to the cooling liquid in the cooling plate 510 through heat transfer. The secondary cooling liquid circulates to the cooling liquid distribution unit 400 through the secondary outlet pipe 540. Then, it exchanges heat with the primary cooling liquid through the heat exchanger, lowering the secondary cooling liquid temperature. The cooling liquid then re-enters the cooling plate 510 through the secondary inlet pipe 530, and the cycle repeats. The primary interface 410 of the cooling liquid distribution unit 400 is connected to the primary circuit in the server liquid cooling room and is re-cooled with an outdoor cooling source through the primary pipe network.
[0057] The above content is only a preferred embodiment of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scope based on the concept of the present invention. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of the present invention.
