Tube-and-fin condenser: The manufacturing process is simple and the heat dissipation efficiency is low.

Tube-and-belt condenser: The radiating fins are composite fins with a total of three pieces. The upper and lower fins are made of aluminum and contain Si.

Parallel flow condenser: The biggest difference between the parallel flow condenser and the tube-and-belt condenser is that the tube-and-belt type has only one flat tube that is bent in a serpentine shape from beginning to end, and the refrigerant only flows in this channel for heat exchange; while the parallel flow condenser The flow condenser is connected by a plurality of flat tubes between the two headers, and the refrigerant circulates through the plurality of flat tubes at the same time for heat exchange. The heat exchange characteristics and refrigerant characteristics of automobile air conditioner condensers should be improved from the following three aspects: increase the heat exchange area and increase the heat exchange between the air side and the refrigerant side. Improve the uniformity of the temperature and flow distribution of the working fluid in the condenser. Reduce the pressure loss of the refrigerant in the condenser, which can reduce the power consumption of the compressor.
