Heat exchanger for use in e.g. air conditioning, has one-piece heat transfer block made of extruded aluminum alloy with interconnected walls forming heat flow columns corresponding to heat flow channels formed on two end sections

摘要

The heat exchanger (1) has a one-piece heat transfer block (2) made of extruded aluminum alloy, and provided with interconnected walls forming heat flow columns (11). The heat flow columns are formed corresponding to the heat flow channels (13) formed on the two end sections (3,4) sealing the ends of the block. Duct connections (12) are formed on the end sections for supplying and discharging hot and cold fluids used in the heat transfer process.
