Heat exchangers and microchannel technology are used in the chemical industry to improve reaction efficiency and temperature control. Heat exchangers cool the reaction system and protect the reactor from high temperature and pressure, while microchannels provide a larger surface area and faster mass transfer rate for improved contact and reaction between reactants. This integration can reduce the reactor's volume and weight, lowering costs and improving production efficiency. The application of these technologies has significant implications for sustainable development and resource utilization in the chemical industry.

Heat exchangers are vital in the power industry, where efficient energy utilization is crucial. Power plants produce waste heat when cooling steam or gas with water. Heat exchangers play a key role in transferring this waste heat to other media, improving energy efficiency. By exchanging heat between high-temperature steam/gas and cooling water, heat exchangers reduce the temperature of the water while utilizing the waste heat. This not only optimizes energy utilization but also minimizes environmental impact in the power industry.
