Chiller with interior cooler-heat exchanger

摘要

The heat exchanger (11) has a tube (22), which has an inner lower pressure channel (25). The lower pressure channel is equipped with the connection at the side of a refrigerant compressor and has high pressure channels equipped with the connection at the pressure side of the refrigerant compressor. The lower pressure channel has a cross section in cylindrical manner. The high pressure channels are arranged around the lower pressure channel and are separated by intermediate walls, which are arranged radically to each other. The tube is manufactured in bent form having small bending radii.
