Sliding vane type working medium pump of two-phase flow refrigerating system

Abstract

The invention discloses a sliding vane type working medium pump of a two-phase flow refrigerating system. The sliding vane type working medium pump comprises an air inlet cover, a bearing seat, a coupling connecting body, a rotor shell and a front press cover of the rotor shell, which are connected in series in sequence, wherein a motor is arranged between the bearing seat and the coupling connecting body; a machine core of a pump body is arranged in the rotor shell and comprises a cylinder body and a rotor shaft arranged in the cylinder body; an air suction hole and an exhaust hole are formed in the cylinder body; the rotor shaft is connected with a motor shaft of the motor through a coupling arranged in the coupling connecting body; multiple sliding vane are arranged on the circumference of the rotor of the rotor shaft in a counterclockwise array; when the machine core of the pump body operates, one of two adjacent sliding vanes is tangent to the hole opening of the air suction hole and the other one of the two adjacent sliding vanes is in contact with the exhaust hole, and the machine core of the pump body stops air suction process and starts exhaust process. According the sliding vane type working medium pump of the two-phase flow refrigerating system, the two-phase flow refrigerating system can stably operate under various working conditions; the energy consumption of the system is saved; working medium is not compressed and is only used for providing power to realize the two-phase flow refrigerating system.

Description

technical field [0001] The invention relates to a power device suitable for an electronic cooling two-phase flow refrigeration system, in particular to a sliding vane working medium pump for a two-phase flow refrigeration system. Background technique [0002] Since entering the 21st century, electronic technology has developed rapidly. While the power of electronic equipment is increasing, the volume is also becoming smaller and smaller, which inevitably produces high heat flux. High temperatures can have significant adverse effects on electronic equipment. From 1990 to 2000, the feature size of microprocessors decreased from 0.35 nm to 0.18 nm. The high integration, packaging density and increasing operating frequency of electronic devices make the heat flux of electronic devices increase rapidly. Studies have shown that more than 55% of the failure causes of electronic equipment are caused by excessive temperature (the remaining factors are dust 6%, humidity 19%, vibrat...
