Embodiment 1

[0063] Such as figure 1 As shown, a backup cooling system for a data center includes a vaporizer 1 and a Venturi mixer 2. The cooling equipment is connected to a liquid nitrogen pipeline. The liquid nitrogen pipeline includes a first pipeline 3 and a second pipeline 4. The first pipeline 3 Input the liquid nitrogen into the vaporizer 1, the vaporizer 1 vaporizes the liquid nitrogen into nitrogen gas and outputs it to the Venturi mixer 2 through the delivery pipeline 5, and the second pipeline 4 inputs the liquid nitrogen into the Venturi mixer 2 Mixed with nitrogen to form a cooling gas, the cooling gas is output to the chamber through the output pipe 6 of the Venturi mixer 2 .

[0064] After the liquid nitrogen in the first pipeline 3 is input into the gasifier 1, the gasifier 1 absorbs and exchanges heat with the surrounding air, thereby completely vaporizing the ultra-low temperature liquid nitrogen in the gasifier 1 and converting it into high-pressure nitrogen gas, increa...

Abstract

The invention discloses a backup cooling system for a data center, and a control method thereof. The cooling system comprises a gasifier and a venturi mixer, a cooling device is connected with a liquid nitrogen pipeline, the liquid nitrogen pipeline comprises a first pipeline and a second pipeline, the first pipeline inputs liquid nitrogen into the gasifier, the gasifier gasifies the liquid nitrogen into gaseous nitrogen and outputs the gaseous nitrogen to the venturi mixer through a conveying pipeline, the second pipeline inputs liquid nitrogen into the venturi mixer to be mixed with gaseous nitrogen to form cooling gas, and the cooling gas is output into a room through the output pipeline of the venturi mixer. According to the invention, the cooling reliability is improved, so that the equipment safety of the whole data center is guaranteed.

Description

technical field [0001] The invention relates to the technical field of cooling, in particular to a backup cooling system for a data center and a control method thereof. Background technique [0002] The cooling object of the data center is mainly electronic information equipment. If the temperature is too high, the probability of electronic equipment overheating and operating failure will increase. At present, the commonly used cooling methods include air-cooled cooling and water-cooled cooling, but the very important link to ensure the reliability of the entire cooling system has not received enough attention in many data centers. Although the design is very thoughtful, it is still unavoidable that some accidents will occur, which will affect the normal operation of the cooling system. At present, liquid nitrogen is also used for cooling, such as the Chinese patent with publication number CN108101356A and publication date 2018.6.1: a method and system for online cooling of...
