Description

technical field [0001] The present application relates to the field of heat transfer equipment, in particular to a visual heat transfer experiment platform for microporous bubbling technology. Background technique [0002] Heat exchangers are widely used in petrochemical, metallurgical power, heating and refrigeration, food and other industries, and play a very important role in the industry. From air conditioners and water heaters in daily life to cooling towers in power plants, improving the heat transfer efficiency of heat exchangers, multiplied by a huge number, has a very considerable economic effect. Therefore, it is necessary to develop more efficient heat exchangers. [0003] Among them, microporous bubbling enhanced heat transfer technology is a new type of enhanced heat transfer technology, involving heat transfer, fluid mechanics and bubble dynamics. Judging from the current research, there is still no unified theoretical system for the study of bubble dynamics. ...
