Answer: The baffle of the evaporator acts like a precooler. Its main function is to "recover" the cold energy carried by the compressed air after being cooled by the evaporator (for most users, this part of the cold energy is "waste cold energy"), and use this part of the cold energy to cool the high-temperature compressed air carrying a large amount of water vapor, thereby reducing the heat load of the cold dryer refrigeration system and achieving the purpose of saving energy.
