  • Patent number: 8793987
    Abstract: A heat exchanger plate for an evaporator includes a flow transverse distribution device. Disks of the flow transverse distribution device conduct the medium to be evaporated to the flow channel extending in the direction of the longitudinal axis. The disks include openings allowing a flow of the medium in the direction of the longitudinal axis with comparatively higher flow resistance than in the direction of the transverse axis. The number of disks arranged one behind the other in the direction of the longitudinal axis varies over the width of the heat exchanger plate in the direction of the transverse axis. On each width section, in which the entry of the medium into the disks arranged one behind the other is intended, the comparatively largest number of disks is provided one behind the other. As the distance from the entrance increases, the number decreases in the direction of the transverse axis.

  • Patent number: 8522862
    Abstract: The invention relates to a cooling fluid cooler for motor vehicles having a soldered cooling network (1) made of flat tubes (101) and ribs (102), produced from very thin aluminum sheets (a, b, c), and having header or loop-around chambers (3) at the ends of the flat tubes (101) for the cooling fluid flowing in the flat tubes (101), said chambers being cooled by cooling air flowing through the ribs (102). The cooling fluid cooler has exceptional cooling power and a light weight. This is achieved according to the invention in that each flat tube (101) is made of at least two formed sheet metal strips (a, b, c), wherein at least the one sheet metal strip (a, b) forms the wall of the flat tube and the other sheet metal strip forms a wavy internal insert (c) forming channels (10) in the same, and that the ratio of the constriction factor on the cooling fluid side to the constriction factor on the cooling air side is approximately in the range of 0.20 to 0.

  • Publication number: 20120266599
    Abstract: The invention relates to a heat exchanger plate for an evaporator; with a longitudinal axis and a transverse axis, with the transverse axis being disposed perpendicularly or substantially perpendicularly to the longitudinal axis; with at least one flow channel which extends in the direction of the longitudinal axis of the heat exchanger plate through a heat supply area of the heat exchanger plate and conducts the medium to be evaporated; with an inlet for the medium to be evaporated, which inlet is in a flow-conducting connection with the at least one flow channel arranged in the direction of the longitudinal axis of the heat exchanger plate, with a meandering inflow channel being provided in the direction of the longitudinal axis between the inlet and the at least one flow channel arranged in the direction of the longitudinal axis, which inflow channel is in a flow-conducting connection with the inlet and the at least one flow channel, and conducts the medium which flows out of the inlet to the at least o
