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...

Problems solved by technology

The pulsating flow generator with the domestic patent number "CN200910060614.8" can preliminarily realize the pulsation of periodically changing fluid flow velocity, but the pulsating flow generator can only realize the adjustment of the pulsation frequency, not the adjustment of the pulsation amplitude, and the pulsation The periodic pulsation of the fluid produced by the flow generator is not precise enough
