HEAT EXCHANGER PLATE AND PLATE HEAT EXCHANGER COMPRISING SUCH A HEAT EXCHANGER PLATE

摘要

A heat exchanger plate has a vertical center axis dividing the plate into a left and a right half delimited by a first and second long side, respectively. A horizontal center axis divides the plate into an upper and a lower half delimited by a first and second short side, respectively. The plate includes a port hole with a reference point that coincides with a center point of a biggest imaginary circle that can be fitted into the port hole. The port hole is arranged within the left half and the upper half. The porthole has a form defined by a number of corner points of an imaginary plane geometric figure of which at least one is displaced from an arc of the circle, and the same number of thoroughly curved lines connecting the corner points. The corner points include first, second and third corner points.

1. A heat exchanger plate having a vertical center axis dividing the heat exchanger plate into a left and a right half delimited by a first and second long side, respectively, a horizontal center axis dividing the heat exchanger plate into an upper and a lower half delimited by a first and second short side, respectively, and a port hole with a reference point coinciding with a center point of a biggest imaginary circle that can be fitted into the port hole, the port hole being arranged within the left half and the upper half, wherein the porthole has a form defined by
a number of corner points of an imaginary plane geometric figure of which at least one is displaced from an arc of the circle, and the same number of thoroughly curved lines connecting the corner points,wherein a first corner point of the corner points is arranged closest to a transition between the first short side and the first long side and on a first distance from the reference point, a second one of the corner points is arranged closest to the first corner point in a clockwise direction and on a second distance from the reference point and a third one of the corner points is arranged closest to the first corner point in a counter clockwise direction and on a third distance from the reference point.
