Liquid separator for improving liquid separating uniformity

Abstract

The invention relates to a liquid separator for improving liquid separating uniformity. The liquid separator comprises an inlet bend pipe of the liquid separator, an inlet straight pipe of the liquidseparator, an outlet branch pipe of the liquid separator and an ultrasonic vibrating mechanism. The ultrasonic vibrating mechanism comprises an ultrasonic generator, a transducer and a vibrating rod.An orifice in one end of the inlet bend pipe of the liquid separator is connected to a throttling member and a liquid inlet pipe of a refrigerating system while the other end of the inlet bend pipe ofthe liquid separator is hermetically connected to an orifice in the bottom end of the inlet straight pipe of the liquid separator, an orifice in the top end of the inlet straight pipe of the liquid separator hermetically communicates to an orifice in the lower end of the outlet branch pipe of the liquid separator, and an orifice in the top end of the outlet branch pipe of the liquid separator isconnected to each branch in an evaporator of the refrigerating system; a vibrating rod through mounting hole is formed in the pipe wall of the inlet bend pipe of the liquid separator, a rod body at one end of the vibrating rod stretches into the inlet straight pipe of the liquid separator through the vibrating rod through mounting hole, the other end is left out of the inlet bend pipe of the liquid separator, and a seal and an angle adjusting member are arranged between the vibrating rod and the vibrating rod through mounting hole; and the transducer is fixedly connected at the outer left endof the vibrating rod, and the transducer is connected to the ultrasonic generator through a wire.

Description

technical field [0001] The invention belongs to the technical field of refrigeration systems, in particular to a liquid separator for improving the uniformity of liquid separation. Background technique [0002] The liquid separator is an important component in the refrigeration system. Its function is to distribute the gas-liquid two-phase refrigerant evenly and equally to each branch of the evaporator, so that the evaporator can maintain good heat transfer performance. [0003] However, in actual working conditions, the most common problem of the liquid separator is the uneven distribution of refrigerant. Since most of the existing liquid separators are conical liquid separators, the liquid separator is greatly affected by the inclination angle during liquid separation. , In the actual installation, the liquid separator cannot guarantee an absolutely vertical state. After the liquid-phase refrigerant coalesces to form a liquid film, it is easier to flow out along the outlet...

Problems solved by technology

[0003] However, in actual working conditions, the most common problem of the liquid separator is the uneven distribution of refrigerant. Since most of the existing liquid separators are conical liquid separators, the liquid separator is greatly affected by the inclination angle during liquid separation. , in the actual installation, the liquid separator cannot guarantee an absolutely vertical state. After the liquid-phase refrigerant coalesces to form a liquid film, it is easier to flow out along the outlet branch pipe in the inclined direction, resulting in uneven liquid separation.

[0004] In the case of uneven liquid separation, the refrigerant in some branches of the evaporator will be distributed too much, which will lead to incomplete evaporation of the refrigerant, thereby affecting the heat transfer performance; while the refrigerant in other branches of the evaporator will be distributed too little , which will cause this part of the pipeline to enter the superheated area in advance, which will greatly reduce the heat transfer coefficient and the heat transfer area will not be fully utilized
