Abstract
A plate and fin heat exchanger in the form of a refrigerant evaporator. The heat exchanger comprises a plate and fin structure providing alternately channels for the flow of refrigerant and spaces for the flow of air. An apertured inlet manifold is in communication with the refrigerant flow channels. A refrigerant distribution tube is inserted into the inlet manifold through the aperture in the latter. The distribution tube is provided with a series of orifices formed in the tube wall in register with the refrigerant flow channels. The improvement comprises a construction and arrangement in which the orifices are directed toward the air inlet side of the heat exchanger. Preferably, the orifices are directed to the air inlet side of the heat exchanger at an acute angle to a horizontal plane, the angularity being on the order of 0.degree. to 15.degree. relative to the horizontal plane and below the latter.
