Embodiment

[0027] Such as figure 1 As shown, a double-loop cooling circulation system for water supply and return includes an inner circulation system including a cooling unit and an outer circulation system including a cooling unit. The cooling unit mentioned here is a cabinet 600, and the supply The cold unit is a cooling tower 700, and the internal circulation system and the external circulation system are connected to realize heat exchange between the two through an intermediate heat exchange unit. The intermediate heat exchange unit is a plate heat exchanger 800, and the internal circulation system and the external circulation system The system adopts a loop design so that the brine can flow in both directions in the pipeline. Specifically, such as figure 2 As shown, the internal circulation system also includes an internal circulation water supply loop 200 and an internal circulation return water loop 100, and the three cabinets 600 are respectively connected to the internal circ...

Abstract

The invention discloses a water-supply water-return dual-loop cooling circulation system. The circulation system comprises an inner circulation system containing a cooled unit, and an outer circulation system containing a cooling unit, wherein the inner circulation system and the outer circulation system are connected through a middle heat exchange unit to realize the heat exchange between the inner circulation system and the outer circulation system; and the inner circulation system and the outer circulation system adopt the loop design, so that a refrigerating medium can flow in the pipeline in a bidirectional manner. The water-supply water-return dual-loop cooling circulation system is capable of realizing accurate refrigerating, rapid and convenient to install and maintain, and capable of avoiding one-way leakage or avoiding a condition that the pipeline cut-off system cannot be operated normally in maintenance.

Description

technical field [0001] The invention relates to the technical field of cooling systems for data center computer rooms, in particular to a cooling cycle system with double loops for water supply and return. Background technique [0002] With the continuous increase of high-density cabinets in the IDC Internet data center computer room, the integration of equipment is getting higher and higher, and the processing capacity is gradually enhanced, which makes the heat generated by the equipment in the cabinet more and more. The traditional air-cooled data computer room, its The indoor air is cooled by the precision air conditioner through the compression refrigeration cycle, and then sent into the computer room through the raised floor. This mode no longer meets the cooling needs of high-density cabinets in the modern computer room, and local overheating, large power consumption, and excessive energy consumption of the computer room air conditioner appear problems such as height ...
