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 stabilizing devices and the pipeline two-phase flow stabilizing device. Background technique [0002] Two-phase flow and instability widely exist in heat exchange devices, scientific research and experimental devices, and industrial production equipment. For example, when fluid enters heat exchange equipment, it will cause water hammer phenomenon caused by space expansion. It will also deteriorate due to the large amount of flow heat exchange. When the vapor and liquid phases of the two-phase working medium are not uniformly mixed and flow discontinuously, the large-sized liquid mass will occupy the space of the vapor mass at high speed, resulting in unstable two-phase flow, which will violently impact the equipment and pipelines, resulting in strong vibration and shock. Noise seriously threatens the safety of equipmen...
