Technical Field

The invention relates to the technical field of condensers, in particular to a condenser.

Background

The parallel flow condenser is a heat exchanger, and is widely applied to industrial departments such as petrochemical industry, oil refining, aviation, light industry, metallurgy, building, atomic energy, power, shipbuilding and the like, such as automobiles, refrigerators and thermal power plants, and especially the field of automobile air conditioning refrigeration, and plays an important role. The heat exchange efficiency of the parallel flow condenser directly affects the performance of the whole refrigeration system. When the refrigerant steam is condensed and exchanges heat in the parallel flow condenser, the liquid refrigerant is continuously accumulated, a formed liquid film is continuously thickened, the liquid film prevents the steam from contacting with the wall surface and is the main thermal resistance of the condensation and heat exchange, the condensation effect is rapidly deteriorated, and the heat exchange coefficient is reduced. The reduction of the heat exchange efficiency of the refrigerant side also influences the heat exchange efficiency of the air side, and the temperature of the outer wall of the tube is reduced due to the increase of the heat resistance of the condensation heat exchange of the refrigerant in the tube, so that the utilization rate of the louver fins is reduced. In order to solve the problems, the conventional condenser mainly meets the refrigeration requirement by increasing the heat exchange area, so that the volume and the weight of the condenser are increased, and the manufacturing cost is higher.
