Flexible counter-flow heat exchangers

摘要

The invention describes a flexible heat exchanger (12) that provides both a direct connection between a cold stage (11) and a compressor module (10) of a refrigeration system (100) and counter-flow heat exchange along the entire connection. It provides methods for making such a heat exchanger (12) and for incorporating the heat exchanger (12) in refrigeration systems (100). The advantages of the present invention are that it makes refrigeration systems (100) modular and easily adaptable; allows the cold stage (11) to be compact in size; and provides an effective counter-flow heat exchange.
