Heat exchanger for heating has means of preventing molten solder from entering intermediate functional cavities of other components

摘要

The heat exchanger (3) has first components (4) with other components (6) having intermediate functional cavities (5), and solder (9) to connect the components. The heat exchanger has devices (14) for preventing molten solder from entering the intermediate functional cavities of the other components. One of the second-type components (6) may include fins forming the intermediate functional cavities.
