Cooling system for data center system and data center system

Abstract

The invention provides a cooling system for a data center system and the data center system. A mixed air chamber and a hot return air layer are connected through a return air port and are arranged inthe same layer; an air supply chamber and a cold pool layer are connected through an air supply port and are arranged in the same layer; a lower air supply chamber is formed in a machine room of the cooling system to flow to the cold pool layer; the cold pool layer flows to the hot return air layer from bottom to top; an upper hot return air layer flows to the mixed air chamber; the mixed air chamber exchanges heat and cools the indoor return air and then flows to a circulating cooling system of the air supply chamber from top to bottom; air current circulation is implemented by fully utilizing the air autoconvection mode of natural descending of cold air and natural ascending of hot air, thereby reducing the mixing of cold and hot air, improving the refrigerating efficiency and recyclingof energy. A diffuse type air supply end is disposed in the air supply port so that the cold air is diffused to the whole cold pool layer in a manner of diffusion, and the negative pressure problem caused by the excessive wind speed of the proximal cabinet of the air supply port and the problem of insufficient cold air volume of the remote cabinet of the air supply port are solved.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, and in particular relates to a cooling system for a data center system and the data center system. Background technique [0002] Refrigeration devices are more and more widely used in daily life. The indoor air temperature is adjusted through refrigeration devices, but pure mechanical refrigeration consumes a lot of energy and has a low energy efficiency ratio. Fresh air direct evaporative cooling has high energy efficiency, but the temperature and humidity control is unstable, and the temperature range that can be adjusted is small. Using natural cooling, the indoor temperature cannot be reduced to the required temperature in hot seasons, especially in indoor heat dissipation temperatures such as data center computer rooms. And in areas that need to be cooled all year round to maintain a certain temperature, natural cooling alone cannot meet the requirements, and only the temperature diffe...

Problems solved by technology

[0006] Therefore, the technical problem to be solved by the present invention is that the existing air supply and return methods of the data center are not energy-saving, and when the air supply speed is too high during use, it is easy to cause the air flow in the data center to be confused, resulting in mixing of hot and cold air, reducing the cooling efficiency.
