Abstract: A device for reinforcing condensation, especially a device being disposed between a compressor and an expansion valve in a condensation system, comprises a front pipe, at least two divided flow pipes, a plurality of capillary tubes, at least a combining pipe, and a rear pipe. The front pipe is connected to a heat exchange pipe in the condensation system. The divided flow pipes are joined to the front pipe and each divided flow pipe has a diameter thereof smaller than that of the front pipe. The capillary tubes are divided into a plurality of groups and each group has two or more of the capillary tubes. The capillary tubes at an end thereof connect with the divided flow pipes and the diameter of the respective capillary tube is smaller than that the diameter of the respective divided flow pipe. The combining pipe at an end thereof connects with the other end of each capillary tube.
