Embodiment Construction
[0019] The present invention will be described in detail below with reference to the accompanying drawings.
[0020] The present invention is a power supply copper strip busbar for centralized power supply of high-density Rack-level cabinets. Since it is a centralized power supply, generally 20 or more nodes share one channel of medium power supply. The current required by so many servers will exceed 600A. Ordinary cables cannot achieve this power supply capability. Therefore, it is necessary to introduce the power supply copper belt bus to supply power to each node of the cabinet.
[0021] The power supply copper strip busbar designed by the present invention can be divided into three functional modules, which are respectively node power supply functional module, cabinet fan wall power supply functional module, and M-type power supply copperbelt busbar fixed-distance functional module, wherein:
[0022] Node power supply function module: Since the power supply copper strip b...

The invention provides a design method for centralized power supply adopting a Rack-level power supply copper strip bus, wherein the power supply adopting the power supply copper strip bus is realized by three function modules which are a node power supply function module, a cabinet fan wall power supply function module, and an M-shaped power supply copper strip bus distance determination function module respectively; in the node power supply function module, because the power supply copper strip bus is used for the power supply, and a node directly gets power from the power supply copper strip bus, a large-current connecting terminal is chosen to realize the hot unplugging-plugging function of the node, and one side of the power supply copper strip bus is milled to be 3 mm thick in the function, with the purpose of facilitating unplugging and plugging for the connecting terminal; and in cabinet fan wall power supply function module, a mode is designed that the terminal is directly fixed on the power supply copper strip bus, a fan wall power supply copper column is fixed on the power supply copper strip bus, a fan wall power-getting copper sleeve is sleeved on the power supply copper column as a connecting terminal to get power, and a whole cabinet fan is divided into four groups, therefore, power is get from only four points on the power supply copper strip bus.
Description
technical field [0001] The invention relates to the technical field of computer server power supply, in particular to a design method for centralized power supply of a Rack-level power supply copper belt busbar. The centralized power supply for Rack-level cabinets replaces the traditional server that must have its own power supply limit, and also breaks through the limitation of cable power supply. Background technique [0002] In today's data application-centric enterprise, people need to process, store and connect more data in a smaller footprint. Storage devices are more compact, servers are mostly blade-type, and one chassis includes multiple servers. Correspondingly, the power supply of equipment should also achieve high density. The power consumption per square meter of a data center is a measure of the energy consumption of a data center. For future new demands and mandatory redundancy considerations, the company needs to face greater expenses. [0003] The servers...
