Power supply system of high-performance computer

Abstract

The invention discloses a power supply system of a high-performance computer. The power supply system comprises a backboard electrical power package for supplying electricity to a computing unit, and a main board electrical power package. The computing unit comprises a backboard and a plurality of main boards connected to the backboard; the backboard electrical power package comprises two power supply groups; each power supply group comprises four primary power modules; the plurality of main boards are divided into two groups in average, and each group of main boards are powered by one power supply group. The power supply system of the high-performance computer disclosed by the invention has the advantages of simple and compact structure, and convenience in manufacture and processing, improving the power conversion efficiency, reducing the power cost and the like.

Description

technical field [0001] The invention mainly relates to the design field of a high-performance computer power supply system, in particular to a power supply system suitable for high-performance computing. Background technique [0002] "High-performance computer" is an important symbol to measure a country's scientific and technological innovation capability and comprehensive national strength. With the wide application of high-performance computers in important fields such as nuclear simulation, weather forecast, aircraft design, biomedicine, and energy exploration, the peak performance requirements of high-performance computers are getting higher and higher, power consumption is increasing, and the size is also increasing. It is getting bigger and bigger, the number of cabinets exceeds dozens or even hundreds, and the floor area exceeds hundreds of square meters or even thousands of square meters, resulting in an increasing area of ​​the computer room. [0003] Currently, t...

AI Technical Summary

Problems solved by technology

At the same time, this kind of motherboard can only be inserted vertically, not horizontally.

When the horizontal insertion method is adopted, because the width direction of the main board is relatively narrow, the appearance of the cabinet will become very narrow and deep, and the shape is ugly

After adopting the vertical insertion method, since several computing units are placed from top to bottom in the cabinet, the ventilation and heat dissipation design is more difficult, and the cold air at the bottom is difficult to be sent to the upper computing units, which makes the uppermost computing unit have a higher ambient temperature. It is easy to cause job instability

If the rear air outlet method is used, when double-sided insertion is used, a large hole needs to be opened on the back panel to absorb the heat generated by the motherboard inserted in front of the back panel. However, after the hole is opened on the back panel It will greatly reduce the wiring space of the printed board on the backplane, increase the number of layers on the backplane, and increase the cost
