1. A plate for a heat exchanger device, the plate comprising:
a first sector with mutually parallel ridges including a first outermost ridge, the first outermost ridge having a first end and a second end;
an adjoining second sector with mutually parallel ridges extending at an angle relative to the ridges of the first sector including a first outermost ridge, the first outermost ridge having a first end and a second end;
a space having a first side extending between the first end and the second end of the first outermost ridge of the first sector and a second side extending between the first end and the second end of the first outermost ridge of the second sector, the space having an increasing width in a first direction; and
at least one Y-shaped first transition ridge formed as a stem in the space between the first sector and second sector, the stem branching off into two legs.
 
13. A plate for a heat exchanger device, comprising:
a first sector with parallel ridges;
an adjoining second sector with parallel ridges extending at an angle relative to the ridges of the parallel first sector;
a first transition ridge between the first sector and second sector, the first transition ridge being Y-shaped with a stem branching off into two legs, wherein the stem has a length exceeding twice a distance from ridge to ridge of the parallel ridges of the first sector; and
a second transition ridge being Y-shaped with a stem branching off into two legs, wherein the stem of the second transition ridge is spaced from the first transition ridge and arranged between the two legs of the first transition ridge.
