Liquid/gas heat exchanger, in particular for an automobile air-conditioning system using a coolant fluid operating in supercritical state, such as CO2

摘要

The coolers (30, 40) have tube bundles (34, 44) provided in an internal space and circulating coolant gas (G) e.g. carbon dioxide, which is cooled by coolant liquid (L) e.g. glycol water, where the cooler defines two channels for the liquid. A common wall (52) is extended parallel to the tube bundles. An inlet tube (42) introduces the liquid in the cooler, and an outlet tube (32) evacuates the liquid that occupies the internal space of the cooler. An independent claim is also included for a cooler module comprising coolers.
