A parallel flow condenser involves a kind of alien parallel flow cooler called a car air conditioner, especially the car air conditioner. The new practical type is to install the long-sealing streaming pipe seal on the side of the condenser based on the existing technology. The collector pipe is relatively parallel, and the short-set stream tube and the short-episode flow pipe are staggered. The fixed connection between the extended set and the brief set flow pipe has a parallel porous flat pipe, and The flow pipes are connected with the brief-episode flow pipe. When the car is idling, the refrigeration device can continue to work to ensure the cooling effect in the vehicle; increase the refrigeration capacity of the car refrigeration device; indirectly increase the heat dissipation of the car water tank, ensure that the water tank is not boiled, so that the car can continue to drive continuously; Structural compact, convenient installation, good refrigeration effect, can make full use of the installation space.
