Heat exchanger e.g. evaporator has injecting pipe and several openings whereby heat exchanger is formed such that flow rate of medium is increased in injecting pipe in range with part of openings

摘要

Heat exchanger has injecting pipe (4), several openings (9') and the injecting pipes are connected directly or indirectly over the several openings. The heat exchanger is formed such that the flow rate of the medium is increased in the injecting pipe in a range at least with a part of the openings. The free cross-section flow of the injecting pipe reduces in normal flow direction.
