Embodiment Construction

[0067] Hereby, the technical content and detailed description of the present invention are described as follows in conjunction with the drawings:

[0068] See image 3 , is a schematic block diagram of a server cooling system with AC and DC power supplies according to the present invention. The server cooling system with AC and DC power supplies is electrically connected to an external AC power supply Vac and an external DC power supply Vdc to drive at least one high-voltage cooling device C1 and at least one low-voltage cooling device C2. The server cooling system includes an AC input subsystem 10 , a DC input subsystem 20 and a drive control subsystem 30 . The AC input subsystem 10 receives the external AC power supply Vac, and provides a first DC voltage Vo1 and a second DC voltage Vo2, wherein the second DC voltage Vo2 is obtained by down-converting the first DC voltage Vo1. In addition, the AC input subsystem 10 further provides a high voltage auxiliary power Vau1. The...

Abstract

The invention discloses a server cooling system with alternating current and direct current power supply and an operation method of the server cooling system with the alternating current and direct current power supply. The server cooling system comprises an alternating current input subsystem, a direct current input subsystem and a drive control subsystem. The alternating current input subsystem receives an external alternating current power source and provides first direct current voltage and second direct current voltage. The direct current input subsystem receives an external direct current power source and provides third direct current voltage and fourth direct current voltage. When the external alternating current power source normally supplies power, the drive control subsystem controls the first direct current voltage and the second direct current voltage to supply power to a high-voltage cooling device and a low-voltage cooling device respectively. When the external alternating current power source abnormally supplies power, and the external direct current power source normally supplies power, the drive control subsystem controls the third direct current voltage and the fourth direct current voltage to supply power to the high-voltage cooling device and the low-voltage cooling device respectively.

Description

technical field [0001] The present invention relates to a server cooling system and its operating method, especially to a server cooling system with AC and DC power supply and its operating method. Background technique [0002] In closed cabinet equipment, in order to ensure the stable operation of the equipment in the cabinet, the waste heat in the cabinet is usually discharged to the outside of the cabinet, so as to maintain the working temperature in the cabinet within the set range. When the traditional fixed-frequency air conditioner is started, the instantaneous current is large, and the vibration and noise are also large. Therefore, the start-up not only consumes power but also causes the life of the compressor to decline. Because most of the traditional cooling systems of cabinet air conditioners use a single power supply mode of AC power or DC power, this indirectly limits the flexibility of the power supply mode of the air conditioning system. In addition, the way...
