Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0016] Such as figure 1 As shown, the multi-channel adjustable pulsating flow generating device includes a water tank 1, an output branch I14, an output branch II15, a bypass III16 and a main road IV17, and the output branch I, the output branch II, and the bypass III The cross-sectional area of ​​each nozzle of the pipeline of the main road IV is equal. Therefore, the flow velocity in the main road IV is the sum of the flow velocities of the output branch I and the output branch II, and the flow direction of the fluid is shown by the arrow in the figure,

[0017] Wherein, the output branch I includes a first frequency-modulated pipeline pump 10 and a first stop valve 11, one end of the first frequency-regulated pipeline pump is connected to the water tank, and the fluid in the water tank is pumped into the output branch I14, and the other en...

Description

technical field [0001] The invention relates to a multi-channel adjustable pulsating flow generating device, which is used to accurately generate pulsating flow periodically changing according to demand in pipelines. Background technique [0002] The core focus of the development direction of heat and mass transfer in the discipline of engineering thermophysics in my country is the three leading technologies that are closely integrated with the development of social economy and science and technology in the world today-biology, information and nanotechnology. At present, the research on pulsating heat transfer focuses on these three aspects. Through the pulsating heat transfer technology, efficient heat dissipation and heat transfer functions can be realized, thermal barrier bottlenecks in important areas can be solved, and energy consumption can be greatly reduced. The research on pulsating heat transfer has gradually entered the micro-nano scale pulsating heat transfer f...
