In the running process of the equipment to be cooled, the first temperature sensor is used for monitoring the temperature of the gas phase area, the second temperature sensor is used for monitoring the temperature of the liquid phase area, the pressure sensor is used for monitoring the pressure of the gas phase area, the liquid level meter is used for monitoring the liquid level of the refrigerant, and the monitoring signals can be transmitted to an external control system through communication connecting wires.
In the running process of the equipment to be cooled, the opening and closing of the pressure regulating valve are controlled by an external control system in communication connection with the pressure regulating valve, and when the positive pressure monitored by the pressure sensor exceeds the positive starting pressure, the pressure regulating valve is opened to release pressure; when the negative pressure detected by the pressure sensor is lower than the negative starting pressure, the pressure regulating valve starts to suck air so as to maintain the pressure in the cabinet body in a normal working range. When the pressure regulating valve cannot work due to abnormal working conditions, the safety valve and the vacuum breaking valve are used as pressure safety devices, and the vacuum breaking valve and the safety valve are mechanical self-opening valves and are automatically opened after the pressure is reached, so that the internal overpressure of the cabinet body is avoided or negative pressure is avoided.
When the equipment to be cooled is operated, operation staff can observe the operation condition inside the cabinet body through the observation holes under the condition that the sealing cover plate is not opened.
In summary, the immersed phase-change liquid-cooled server cabinet can avoid waste caused by dissipation of refrigerant in the cabinet; meanwhile, the condensing pipes are arranged on the side face of the cabinet body, so that the operation, maintenance, taking and placing of equipment to be cooled are facilitated, the condensing pipes do not need to be additionally disassembled and assembled, and the risk of damage to the equipment to be cooled caused by leakage of secondary refrigerant is avoided; the sealable transparent plate arranged on the sealing cover plate ensures that the running condition of the refrigerant in the cabinet body is more visual when the refrigerant boils, and can assist operation and maintenance personnel to check the equipment state; the deployment is flexible and the expansibility is strong.
It will be apparent to those skilled in the art that various modifications and variations can be made in the present application without departing from the spirit or scope of the application. Thus, if such modifications and variations of the present application fall within the scope of the claims and the equivalents thereof, the present application is intended to cover such modifications and variations.
