Server cabinet and data center with same

Abstract

The invention discloses a server cabinet and a data center with the same. The server cabinet comprises a cabinet body, a plurality of servers, a main power supply, a power bus-bar, a battery management module and a plurality of battery modules, wherein the servers and the main power supply are arranged in the cabinet body; the main power supply is connected with commercial power, and converts the commercial power into direct current of which a voltage value is first voltage; the power bus-bar is arranged outside the cabinet body, is connected with the main power supply and the servers, and is used for supplying power to the servers by adopting the direct current of which the voltage value is the first voltage; the battery management module and the battery modules are arranged in the cabinet body, and are connected with the power bus-bar; and the battery management modules are used for supplying power to the battery modules by adopting the direct current of which the voltage value is the first voltage when the main power supply normally supplies the power, and supplying the power to the servers by adopting direct current output by the battery modules when the main power supply is abnormal. The main power supply is directly connected with the servers, and the commercial power is directly supplied to the servers after being rectified, so that efficiency is improved; and in addition, the battery modules are independently controlled by the battery management module, so that high safety is ensured.

Description

technical field [0001] The invention relates to the technical field of power supply for a server room, in particular to a server cabinet and a data center with the server cabinet. Background technique [0002] At present, UPS (Uninterrupted Power System, uninterruptible power supply) + lead-acid battery power backup system is mainly used to supply power to the servers in the computer room. figure 1 It is a schematic diagram of a power backup system in the prior art. Such as figure 1 As shown, the UPS includes a rectification module and an inverter module. First, the rectification module rectifies the AC mains power into DC power, and then the inverter module inverts the DC power into AC power and transmits it to the server rectification module, and then the server rectification module converts the AC power delivered by the UPS. It is rectified into direct current and supplied to the server. When the mains power is abnormal, the inverter module inverts the direct current o...

AI Technical Summary

Problems solved by technology

[0004] (1) The UPS needs to go through the process of rectification and reverse flow before supplying power to the server. There are many intermediate steps, resulting in large power loss and low efficiency;

[0005] (2) Since the input and output of UPS are AC, the management and paralleling are relatively complicated, and only professionals can maintain it, which requires high human resource costs
