Abstract:
1. A heat exchanger plate for an evaporator, comprising: a longitudinal axis; a transverse axis which is disposed perpendicularly to said longitudinal axis; a heat supply area of the heat exchanger plate; one of at least one flow channel and a plurality of said flow channels each of which extends in a direction of said longitudinal axis of the heat exchanger plate through said heat supply area of the heat exchanger plate and which conducts a medium to be evaporated; an inlet; an outlet, said inlet and said outlet being for said medium to be evaporated, said inlet and said outlet being in a flow-conduction connection with said at least one flow channel extending in said direction of said longitudinal axis of the heat exchanger plate; a first transverse flow distribution device provided in said direction of said longitudinal axis between (a) one of said inlet and said outlet and (b) said at least one flow channel extending in said direction of said longitudinal axis, said first transverse flow distribution device compensating a plurality of pressure losses in a flow of said medium to be evaporated which are caused by a length of a flow path one of (a) between said inlet and a plurality of positions of an entrance into said at least one flow channel, and (b) in a case of said plurality of flow channels extending adjacent to one another in said direction of said longitudinal axis between said inlet and a plurality of entrances of said plurality of flow channels, said first transverse flow distribution device including a plurality of first plates, for forming said first transverse flow distribution device in said direction of said longitudinal axis between said inlet and said at least one flow channel extending in said direction of said longitudinal axis said plurality of first plates are arranged and are disposed one behind another in a direction of said longitudinal axis, extend in said direction of said transverse axis, and conduct said medium to be evaporated to said at least one flow channel extending in said direction of said longitudinal axis, said plurality of first plates having a plurality of first openings which enable said flow of said medium to be evaporated in said direction of said longitudinal axis with a comparatively higher flow resistance than in said direction of said transverse axis, a number of said plurality of first plates arranged behind one another in said direction of said longitudinal axis varying over a width of the heat exchanger plate in said direction of said transverse axis, a comparatively largest said number of said plurality of first plates being arranged behind one another in a width section in which an entrance of said medium to be evaporated is provided into successively arranged said plurality of first plates, said number decreasing with an increasing distance from said entrance into said successively arranged plurality of first plates in said direction of said transverse axis, said medium to be evaporated flowing into said first transverse flow distribution device in said direction of the longitudinal axis.
