Abstract

The invention discloses a containerized data center refrigerating system with phase-change natural cooling and belongs to the technical field of heat dissipation of a containerized data center. The system comprises a refrigerant fluorine pump, an indoor evaporator and an outdoor condenser, wherein the indoor evaporator and the outdoor condenser are connected through a copper pipe in a closed manner. The system is filled with a certain amount of low-boiling-point refrigerant, the fluorine pump circulates the refrigerant in the system and forces the refrigerant to pass through the evaporator, indoor hot air releases heat to the refrigerant in the evaporator, the refrigerant absorbs heat and a small number of evaporator absorbs heat and is evaporated; refrigerant liquid with bubbles is circulated into the condenser, and the heat carried by the refrigerant liquid is released into atmosphere; the refrigerant becomes supercooled liquid after heat releasing, so that outdoor cold air can cool the indoor hot air under the condition without contact. In the system, the fluorine pump forces to circulate the refrigerant liquid and flow through the evaporator, the flow velocity of the condenser is increased, and the heat exchange efficiency is improved. On the other hand, the relative position and distance of mounting of the evaporator and the condenser are not limited, the mounting is convenient, and the structure is flexible.

Description

technical field [0001] The invention discloses a refrigeration system for a container data center, which belongs to the technical field of heat dissipation for a container data center; in particular, it is a refrigeration system for a container data center with phase change natural cooling. Background technique [0002] To put it simply, the container data center means that the datacenter is not located in the computer room, but is installed in the container, with network and power supply. The container is divided into two parts, one is the power supply part, and the other is the rack on which many rack-mounted servers are placed. With the rapid development of container data centers, data centers are responsible for increasingly complex task processing tasks, and more and more application loads bring infinite pressure to data centers, while data centers continue to generate heat while providing services for users. As the workload of the data center intensifies, the cooling ...
