Heat exchanger capillary tube routing

摘要

A heat exchanger assembly and subassembly having a combination of liquid line header and a series of spaced helically wound capillary tubes. The liquid line header is mounted such that capillary tubes may be connected therefrom to the appropriate feeder tubes or other connections of the heat exchanger. Capillary tubes are helically wound about the liquid line header such that a compact, neat capillary tube arrangement is provided with a short distance between the two ends of the capillary. A dummy header may be utilized such that the capillary tube extends through the dummy header to a feeder tube to feed the appropriate refrigerant circuit.
