Data room heat pipe air conditioner system with CO2 as refrigerant

Abstract

The invention provides a data room heat pipe air conditioner system with CO2 as a refrigerant. The data room heat pipe air conditioner system comprises at least one heat pipe condenser and a pluralityof heat pipe evaporators arranged on the side faces of all cabinets. All the heat pipe evaporators and a plurality of small fans form cooling units correspondingly, and the cooling units are installed on the side faces of all the cabinets correspondingly. No seal side plate is arranged between adjacent cabinets. The fans can be moved out of the cooling units and are overhauled or replaced. The multiple heat pipe evaporators are in parallel connection and are connected with the heat pipe condensers through gas pipes and liquid pipes. The heat pipe condensers are arranged outside a data room and are cooled by cold water from a cooling tower or a refrigerator. The heat pipe air conditioner system adopts the CO2 as the refrigerant in a heat pipe. According to the data room heat pipe air conditioner system, efficient heat discharge of the data room can be achieved, working conditions of high-pressure operation of the CO2 heat pipe can also be met, and application of an environment-friendlyworking medium is facilitated.

Description

technical field [0001] The invention relates to the field of data room air conditioners, in particular to a CO 2 The heat pipe air conditioning system for the data room as the refrigerant. Background technique [0002] In recent years, due to the high heat generation and high heat dissipation density in the data center, the energy consumption of its air conditioning system has attracted much attention. At present, the cabinet-level separated heat pipe system has been more and more recognized because of its nearby heat dissipation, high efficiency and energy saving features. The cabinet-level separated heat pipe system installs the evaporator of the heat pipe on the back panel of each cabinet. The heat pipe evaporators on multiple cabinets are connected in parallel and share one or more heat pipe condensers. Between the heat pipe evaporator and the condenser It is connected by air pipe and liquid pipe. The heat pipe condenser is installed outside the machine room and can b...

Problems solved by technology

CO 2 It is a natural and environmentally friendly working fluid with good flow and heat transfer performance. It is of great significance for energy saving and environmental protection to use it as a refrigerant instead of Freon in the heat pipe system of the data center. However, in the temperature environment of the data center, CO 2 When used as a refrigerant in the pipe, the working pressure of the heat pipe is as high as 5-7MPa. Considering the pressure resistance requirements of the system, the inlet and outlet of the heat pipe evaporator cannot be connected by a hose, that is, the heat pipe evaporator is required to be fixed. If it is still in accordance with the existing cabinet The rear panel heat pipe evaporator will inevitably lead to the inability to open the rear cabinet door and affect normal use
