Abstract
The utility model discloses an end cover edge plate, a parallel flow heat exchanger and an air conditioning device. The end cover edge plate is used for connecting and plugging two flow collecting tubes in the parallel flow heat exchanger. The end cover edge plate is designed in a dumbbell shape in whole and is provided with a strip-shaped edge plate portion used for connecting the two flow collecting tubes and end cover portions located at two ends of the edge plate portion and used for plugging the two flow collecting tubes. Each end cover portion is designed to be a circular shape and matched with an inner cavity in each flow collecting tube. Due to adoption of the integrally arranged end cover edge plate, a tradition end cover and an edge plate are connected to be a whole, overall intensity and stability of the parallel flow heat exchanger are improved, manufacturing procedures are reduced and production efficiency is improved. In addition, the end cover portions at the two ends of the end cover edge plate are fixed with the flow collecting tubes, compared with a traditional parallel flow heat exchanger, degree of freedom is reduced and therefore stability of the end cover edge plate and reliability of the parallel flow heat exchanger are increased.
