An electronic equipment cooling system with auxiliary cooling device

Abstract

Embodiments of the present invention disclose an electronic equipment cooling system including: a cabinet; at least one electronic equipment chassis that is installed inside the cabinet; and an auxiliary cooling device including an air pressurizing device, an air supply plenum box, and an air-guiding device. The air supply plenum box is disposed on an inner side of the cabinet. The air pressurizing device is disposed at the top or bottom of the cabinet, and an air exhaust on a sidewall of the air pressurizing device is connected to a corresponding air intake on a sidewall of the air supply plenum box. The air-guiding device is installed inside the electronic equipment chassis, an air intake of the air-guiding device is connected to an air exhaust of the air supply plenum device, and an air exhaust of the air-guiding device faces a component inside the electronic equipment chassis.

Description

technical field [0001] The invention relates to the technical field of machine room cabinet cooling, in particular to an electronic equipment cooling system with an auxiliary cooling device. Background technique [0002] The components of electronic equipment will generate heat during operation, causing the temperature of the device to rise. If the temperature of the device exceeds the operating range, it will cause changes in electrical performance and cause the device to fail. Therefore, to ensure the normal operation of the equipment, The equipment must be effectively cooled. [0003] In the prior art, the server is a relatively common type of electronic equipment, which is generally installed on a 19-inch rack in a standard industrial cabinet. When installing a rack-mounted electronic equipment case such as a server, after the electronic equipment case is installed on the rack, there is a certain gap between the electronic equipment case and the side plate of the cabine...

AI Technical Summary

Problems solved by technology

[0007] In the existing technology, from the perspective of thermal management in the computer room, in the down-flow fan room, the cabinets are mostly arranged in the form of hot and cold aisles, and the air from the air conditioner enters the raised floor and is sent to the electronic equipment chassis through the perforated floor in the cold aisle. On the inlet side, after passing through the electronic equipment chassis, the hot air is exhausted to the hot aisle and returned to the air conditioner for recooling. However, when the power of a single cabinet exceeds 4kw, due to insufficient cooling air, the hot air in the hot aisle will flow back from the top of the cabinet In the cold aisle, the temperature difference between the upper and lower inlets of the cabinet becomes larger, which makes the inlet temperature of the electronic equipment chassis on the upper part of the cabinet too high, resulting in the problem of overheating of the inlet temperature

[0008] Therefore, in the prior art, the defects of the electronic equipment system include: the air volume distribution is unreasonable, and the devices with high calorific value cannot be effectively cooled; the cascade connection of the front and rear air duct devices will lead to poor cooling effect of the rear devices; Electronic equipment overheating due to high inlet temperature
