Safety water circulating system

Abstract

The invention relates to a safety water circulating system in a server cabinet. A water storage portion is arranged on the lower portion of a closed water tank, a cavity is reserved on the upper portion of the closed water tank. An outlet end of a cooling system is communicated with the cavity on the upper portion of the closed water tank through a second water outlet pipeline, an inlet end of the cooling system is connected with a water outlet end of a water pump through a second water inlet pipeline, a water inlet end of the water pump is connected with a second connector of a second three-way electromagnetic valve through a first water return pipeline, a first connector of the second three-way electromagnetic valve is connected with an outlet end of a surface cooler through a first water outlet pipeline, the bottom of the water storage portion of the closed water tank is connected with a first connector of a first three-way electromagnetic valve through a water drainage pipeline, the water pump is connected with a first contact of a second signal processor through a wire, the first three-way electromagnetic valve is connected with a second contact of the second signal processor through a wire, the second three-way electromagnetic valve is connected with a third contact of the second signal processor, and a vacuum unit is communicated with a cavity of the closed water tank through a vacuumizing pipeline. The safety water circulating system guarantees safety of IT (information technology) equipment in the cabinet. The safety water circulating system can reasonably effectively utilize space, and is simple and reliable in structure and convenient to mount and adjust.

Description

technical field [0001] The invention relates to a safe water circulation system in a server cabinet. Background technique [0002] The cooling water circulation system in the cabinet maintains a certain value of negative pressure, the cooling water circulation system operates under negative pressure conditions, and the operating environment pressure of the cabinet is greater than the pressure in the cooling water circulation system. [0003] When the cabinet adopts the cooling water circulation system installed on the upper part of the cabinet or in the cabinet to cool down, once the cooling water circulation system in the cabinet leaks, the water will not flow out, but will be sucked back into the pipeline system, which will not affect the IT equipment in the cabinet. Ensure the security of IT equipment in the cabinet. [0004] When the water pump pressure in the cooling water circulation system is transmitted to the closed water tank, it is equal to the negative pressure ...

AI Technical Summary

Problems solved by technology

When the cooling water circulation system is installed on the top of the cabinet or in the cabinet, once the cooling water circulation system in the cabinet leaks and the water flows into the cabinet, it will affect the IT equipment in the cabinet and cannot ensure the safety of the IT equipment in the cabinet

[0006] In the original cooling water circulation system, only the water leakage sensor is generally installed. Since the operating pressure of the water pump is greater than the operating environment pressure of the cabinet, once a large leakage occurs in the cooling water circulation system in the cabinet, the water pump will not stop running immediately, and water will be sprayed into the cabinet. , affecting the security of IT equipment in the cabinet
