Problems solved by technology

In this way, on the one hand, the efficiency of the heat exchanger is adversely affected at a given size; on the other hand, in areas where these media are almost stagnant, particles entrained by the media can deposit and condense into large-scale deposits
In the case, for example, of the heat exchanger being the oil cooler of a car engine, the self-shedding of such large deposits can be detrimental to the entire system

Embodiment Construction

[0022] The plate element shown in FIG. 1 comprises a base 1 with two openings 2, 3 of the first type arranged opposite each other in the flow direction of the medium, both of which have edges 2a, 3a inside the base 1 . The two first openings 2 , 3 are each elongate, wherein the longitudinal diameter of the openings 2 , 3 is more than about 1.5 times the transverse diameter. The flow of the medium is perpendicular to the longitudinal direction of the openings 2,3. In this view, the plate element is rectangular in shape, its corners being significantly rounded. The two first openings 2 , 3 are arranged in corner regions of the same longitudinal side of the rectangle.

[0023] On the opposite other longitudinal side there are openings 4, 5 of a second type which are identical in shape and opening size to the first openings 2, 3. The edges 4a, 5a of the second openings 4, 5 are not at the same height as the bottom 1, but lie in a plane parallel to the bottom surface on which th...

Abstract

The invention relates to a plate element for a plate heat sink, comprising an outer edge (8a) which at least partially surrounds the plate element and lies substantially in a plane, the outer edge (8a) forming a circumferential side wall (8) ); a bottom (1) in the bottom surface, which has a plurality of first openings (2, 3) for the medium to flow through, at least one opening as a perforation of the bottom; and at least one second opening (4) , 5), wherein the opening edges (4a, 5a) of the second opening are located in a plane parallel to the bottom, and the plane and the bottom are staggered in the vertical direction. According to the invention, the second edge of the plate element at least partially surrounds a base surface (6, 7) substantially parallel to the bottom (1), wherein the base surface (6, 7) extends at least from the second opening (4, 5) Extends to the side wall (8) and is staggered from the bottom in a direction perpendicular to the bottom surface.

Description

technical field [0001] The invention relates to a plate element for a plate radiator and also to a plate radiator comprising a plurality of identical plate elements. Background technique [0002] Plate radiators are known in the prior art on which generally identical, alternately arranged plate elements are superimposed and at the same time two separate chamber systems are formed, wherein the first A heat transfer medium flows through one chamber system and a second medium flows through the other chamber system. But generally speaking, there are problems in how to optimize the medium flow path in the chamber so that the heat exchange between the two media is as optimal as possible given the size of the structure and the number of plates. [0003] DE 19939264 A1 describes a plate-plate heat exchanger of stacked construction. In such a heat exchanger, a plurality of identical plate elements are stacked on top of each other and brazed to each other along their conical outer e...
