This article presents a design scheme using topology optimization technology to address the heat dissipation issue of the fluid plate in the plate microchannel reactor’s heat exchanger. The topology optimization method is used in designing the flow channel for the heat dissipation of the heat exchanger fluid plate of the microchannel reactor. By comparing the flow channel obtained through topology optimization with the traditional multi-parallel flow channel, it was discovered that the import and export pressures drop, maximum temperature, and root mean square of temperature of the flow channel obtained through the topology optimization method are more effective than those of the traditional multi-parallel flow channel. This offers a novel approach toward the optimization of heat exchanger plate design for plate-type microchannel reactors.
