Description

technical field [0001] The invention relates to the field of testing thermal performance of heat exchangers, in particular to an online evaluation system for thermal performance of modularized heat exchangers. Background technique [0002] At present, heat exchangers are important equipment in industrial production and are widely used in petroleum, chemical, low-temperature refrigeration, power, energy and other fields. In order to improve energy utilization efficiency, new heat exchangers with higher heat transfer efficiency must be developed. Before the new heat exchanger is put into use, a large number of experiments are required to test its thermal performance, so as to facilitate the thermal design calculation of the heat exchanger. At present, the thermal performance experiments of heat exchangers are mainly carried out in the laboratory. The advantage is that it is convenient and fast. The disadvantage is that there are few types of fluids used in the experiment, and...
