Abstract
Disclosed is an evaporator, particularly for air conditioning installations in automotive vehicles, comprising an evaporator block including several evaporator tubes and coolant supply means. The coolant supply means comprise an expansion valve, a feed tube and a manifold from which the evaporator tubes extend. A calming line segment for the coolant is arranged within the manifold. A distributing space connected with the calming segment is located adjacent to the calming segment. Means are provided for deflecting the coolant between the calming segment and the distributor space.
Claims16
An evaporator for air conditioning installations in automotive vehicles, comprising:
- an evaporator block including a plurality of evaporator tubes;
- and
- a coolant supply means including an expansion valve for producing a mixed phase gas-liquid coolant medium, a feed tube connected to the outlet of said expansion valve and having a configuration which produces at least some separation of the gas and liquid coolant phases, and a manifold connected between said feed tube and said evaporator tubes to distribute coolant to said evaporator tubes, wherein said manifold comprises means, including a calming line segment of sufficient length disposed within the manifold for providing uniform mass flow of the mixed phase coolant over the cross section of the calming line segment, a distributing chamber downstream of the calming line segment for distributing the flow of coolant from the calming line segment to said evaporate tubes, and means for deflecting the flow of coolant, disposed between the calming line segment and the distributing chamber.
