Electronic device cooling system with auxiliary cooling device

Abstract

An embodiment of the invention discloses an electronic device cooling system with an auxiliary cooling device. The electronic device cooling system is used for cooling devices with high heating value in an electronic device machine case. The electronic device cooling system with the auxiliary cooling device comprises a machine cabinet, at least one electronic device machine case which is installed in the machine cabinet, and the auxiliary cooling device. The auxiliary cooling device comprises an air supercharging device, an air supply static pressure box and an air guide device. The air supply static pressure box is arranged on the inner side of the machine cabinet. The air supercharging device is arranged at the top or the bottom of the machine cabinet, and an air outlet on a lateral wall of the air supercharging device is communicated with a corresponding air inlet on a lateral wall of the air supply static pressure box. The air guide device is installed in the electronic device machine case, an air inlet of the air guide device is communicated with an air outlet of the air supply static pressure box, and an air outlet of the air guide device is aligned at the devices in the electronic device machine case.

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
