Heat exchanger is an indispensable equipment to transfer heat, and its efficiency directly affects the overall energy utilization rate and production economic benefits of the equipment. Because the plates of plate heat exchanger are different and the flow channels are different, there is great uncertainty in the design process of plate heat exchanger. The basic principle of the heater is to use different heat transfer media for heat exchange, which is a great embodiment of better utilization of resources. Therefore, the methods of improving heat exchange efficiency and improving energy utilization rate are the prerequisite problems in heat exchanger research. In actual production conditions, due to the limitations of the volume, weight and processing technology of the heat exchanger, the method of simply increasing the plate area to improve the heat transfer performance has limitations. Therefore, improving the flow channel design inside the plate heat exchanger to improve the heat transfer rate per unit volume is an important method to improve the heat transfer performance. In this paper, a computational fluid dynamics model based on thermal energy application is studied to analyze the heat transfer characteristics of plate air heaters and formulate optimization strategies.
