Planar element for forming heat exchanger
Planar element adapted to form, when stacked with a plurality of other such elements, a heat exchanger, comprising an inlet region, a first zone adapted to direct flow from the inlet region towards a second zone, a second zone comprising at least one cutout in the plane of the planar element, adapted to accommodate a cooling core, a third zone, adapted to direct flow from the second zone towards an outlet region and an outlet region, the planar element comprising a first blockage protrusion disposed along a first group of said side edges, the first group comprising at least a side edge adjacent to said outlet region, and a second blockage protrusion disposed along a second group of said side edges, the second group comprising at least a side edge adjacent to said inlet region.
1. A planar element adapted to form, when stacked with a plurality of other such elements, a heat exchanger, the planar element comprising:
an inlet region,
a first zone;
a second zone;
a third zone;
an outlet region, wherein a perimeter of the planar element comprises side edges;
a first blockage protrusion disposed along a first group of said side edges, the first group comprising at least a side edge adjacent to said outlet region, the first blockage protrusion being adapted to block flow from said inlet region directly to said outlet region; and
a second blockage protrusion disposed along a second group of said side edges, the second group comprising at least a side edge adjacent to said inlet region, the second blockage protrusion being adapted to block flow from said outlet region directly to said inlet region;
wherein the first zone is adapted to direct flow from the inlet region towards the second zone;
wherein the second zone comprises at least one cutout in the plane of the planar element, adapted to accommodate a cooling core; and
wherein the third zone is adapted to direct flow from the second zone towards the outlet region.
2. The planer element of claim 1 further comprising at least one first guiding protrusion adapted to guide the airflow within said first region from the inlet region.
3. The planer element of claim 1 further comprising at least one second guiding protrusion adapted to guide the airflow within said third region toward the outlet region.
4. The planer element of claim 1 further comprising at least one third protrusion is disposed in said first region and adapted to keep a defined gap between said planar element and a second planar element disposed adjacent to the planar element, in the inlet region.
5. The planer element of claim 1 further comprising at least one fourth protrusion is disposed in said third region and adapted to keep a defined gap between said planar element and a second planar element disposed adjacent to said planar element, in the outlet region.
6. The planer element of claim 1 further comprising at least one fifth protrusion disposed around said cutout adapted to keep a defined gap between said planar element and a second planar element disposed adjacent to the planar element, in the cutout region.
7. The planar element of claim 1 further comprising at least a first set of relatively parallel protrusions adapted to guide the airflow within said first region.
8. The planar element of claim 1 further comprising at least a second set of relatively parallel protrusions adapted to guide the airflow within said third region.
