Abstract

The invention provides a heat exchanger system provided with a plurality of two-phase flow stabilizing devices and a pipeline of the heat exchanger system. The two-phase flow stabilizing devices are arranged in the pipeline; each of the two-phase flow stabilizing devices comprises a core body; the core body can divide two phase flow runners in the pipeline into a plurality of small runners; and the two-phase flow stabilizing devices are continuously arranged or arranged at intervals. According to the invention, the two-phase flow stabilizing devices are continuously arranged or arranged at intervals, so that the liquid phase and the gaseous phase can be separated through a plurality of stages and steps, heat transfer can be further enhanced, and the effects of vibration and noise reduction are realized.

Description

Technical field [0001] The invention relates to a heat exchanger device, in particular to a heat exchanger system arranged with a plurality of two-phase flow stabilization devices and a pipeline two-phase flow stabilization device thereof. Background technique [0002] Two-phase flow and instability are widely present in heat exchange equipment, scientific research experimental equipment and industrial production equipment. For example, fluid entering the heat exchange equipment will cause water hammer phenomenon caused by space expansion, which is also caused by a large amount of production and will deteriorate. Heat transfer. When the vapor and liquid phases of the two-phase working fluid are not uniformly mixed and flow discontinuously, the large-sized liquid mass will occupy the space of the vapor mass at a high speed, causing the two-phase flow to become unstable, thereby violently impacting the equipment and pipes, causing strong vibration and Noise seriously threatens the...
