Description

Technical field [0001] The invention relates to the field of testing the thermal performance of a heat exchanger, in particular to an online evaluation system for the thermal performance of a modular heat exchanger. Background technique [0002] At present, heat exchangers are important equipment in industrial production and are widely used in petroleum, chemical, cryogenic refrigeration, power, energy and other fields. In order to improve energy efficiency, new heat exchangers with higher heat transfer efficiency must be developed. A large number of experiments are needed to test the thermal performance of the new heat exchanger before it is put into application, so as to facilitate the thermal design calculation of the heat exchanger. At present, the thermal performance experiments of heat exchangers are mainly conducted in laboratories. The advantage is that it is convenient and fast. The disadvantage is that there are fewer types of fluids used in the experiment and it is di...
