Claim:
1. A plate cooler for fluids comprising: a collection box at a first side of the plate cooler, the collection box defining a first fluid channel having an outlet; a distributor box at a second side of the plate cooler opposite the first side, the distributor box defining a collection chamber and a second fluid channel having an inlet, wherein the first fluid channel and the second fluid channel form a continuous fluid channel; and a parallelepiped-shaped package of plate bodies, the plate bodies having first and second ends and a width, the plate bodies having constant thicknesses from their first ends to their second ends, the plate bodies forming spaced-apart fluid channels, the plate bodies communicating at their first and second ends with the first and second fluid channels in the distributor box and the collection box, respectively, wherein the widths of the plate bodies at the first and second ends is essentially the same as the widths of the collection box and the distributor box, respectively, wherein the plate bodies, the distributor box and the collection box are each embodied as an extruded aluminum profile, wherein the distributor box and the collection box are oriented transversely with respect to the plate bodies, wherein the distributor box and the collection box each have ribbed bodies, and each have receiving slots defined by straight opposing slot walls to respectively receive the first and second ends of the plate bodies, wherein the receiving slots: a) extend over the widths of the collection box and the distributor box and are defined within the wall of the collection box and distributor box so that the ends of the plate bodies do not pass the inner wall of the collection box and distributor box when the plate bodies are inserted into the receiving slots, b) have curved peripheries adjacent the first and second fluid channels, and c) open into the second fluid channel via a collection chamber, and wherein a distance between the opposing straight slot walls of the slots continuously narrows along straight lines from an entry portion to an interior portion of the receiving slots, thereby forming acute angles between the opposing straight slot walls, narrowing to a distance corresponding to the thickness of the respective plate bodies such as to enable a fluid-tight surface mating between sides of the ends of the plate bodies and the narrowing slot walls.
