Description

Technical Field

[0001] The utility model relates to the field of data center computer rooms, and in particular to a data center double-circuit input PDU unit. Background Art

[0002] As server power consumption increases, the power density of a single cabinet is rising significantly. According to the 2020 Global Data Center Survey Report released by Uptime Institute, the power density of a single cabinet in a global data center reached 8.4kW / cabinet in 2020, a significant increase from 5.6kW / cabinet in 2017. It is expected that the power density of data centers will continue to rise in the future, and the proportion of high-density data centers will continue to increase.

[0003] Existing data centers use new power supply methods to meet the power requirements of single cabinets, including intelligent small busbar systems or high-voltage DC power supply. Old data centers generally use the form of header cabinets. Each cabinet circuit is 32A, and the design power of a single cabinet is less than 6kW. It is equipped with a 32A PDU unit. If users need to add new high-power servers or other equipment, the power demand in the cabinet cannot be met. The traditional solution is to transform or replace a new header cabinet, change the single cabinet circuit to 63A or larger specifications, and replace the PDU with 63A or larger specifications to meet the power demand of high-power cabinets. This approach is costly and has a long transformation cycle. The utility model provides a new technical solution to solve the power distribution problem of cabinet power in traditional data centers. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the problems existing in the prior art and provide a data center dual-circuit input PDU unit.

[0005] In order to solve the above problems, the technical solution of the utility model is as follows:

[0006] A data center dual-circuit input PDU unit includes a shell, a socket module is arranged on the shell, each socket module is provided with a plurality of jacks, and each socket module is dual-circuit power input, that is, the two ends of the socket module respectively input power of different circuits.

[0007] A connection terminal is arranged at the end of the socket module.

[0008] The terminal blocks can also be connected to cables via industrial connectors.

[0009] Each input circuit is equipped with a circuit breaker protection switch, and the circuit breaker protection switch is arranged on the socket module.

[0010] The housing is provided with an intelligent display screen, and the display screen displays power supply information.

[0011] This dual-circuit input PDU unit is customized for the data center environment. It adopts a dual-circuit input mode and can be connected to two power input circuits of the terminal cabinet. The PDU of the traditional data center is a single-circuit input PDU, which is connected to one power input circuit of the terminal cabinet. The single circuit is 32A and the power of a single cabinet is 6kW. The dual-circuit PDU can be connected to two power input circuits of the terminal cabinet. The single circuit is 32A and the power of a single cabinet can reach 12kW. The power distribution upgrade of the single cabinet power can be achieved without modifying or replacing the terminal cabinet.

[0012] Beneficial effect: The main shell size of the PDU described in the utility model is the same as that of the traditional PDU, and can be directly fixed on the back side of the cabinet. Through the dual-circuit design, each PDU can realize upper and lower power distribution circuit inputs, with a maximum of 6kW on each circuit and a maximum PDU input of 12kW, thereby meeting the increasing power demand of the cabinet without expanding the capacity of the distribution cabinet; the PDU can be configured with socket modules of different quantities and specifications according to user requirements, and has intelligent functions such as remote monitoring, power measurement and power control, to help users understand the power consumption of the cabinet.
