Abstract
The invention relates to a cooler for use as a heat sink for electrical components or circuits consisting of several cooler layers which are joined flat to one another, which are stacked on top of one another, which form between channels through which coolant flows and which each discharge into at least one first collection space for supply of the coolant and into a second collection space for draining the coolant, the collection spaces being formed by openings in the cooler layers and the cooling channels by structuring at least one area of the coolant layers with openings, the area being between the openings.
Claims28
A cooler for use as a heat sink for electrical components or circuits, comprising a plurality of cooler layers,
- which are joined flat to one another, are stacked on top of one another and, wherein flow paths are formed through which a coolant flows and discharges into at least one first collection space for supply of the coolant and into a second collection space for draining the coolant,
- said first and second collection spaces being formed by first and second openings in said cooler layers,
- said flow paths are formed by structuring at least one area of the cooler layers as a screen,
- said screen having a plurality of openings which are formed by material crosspieces which branch in the manner of a network and which form a polygonal ring structure around each of said plurality of openings,
- wherein adjacent cooler layers adjoin one another such,
- that said material crosspieces overlap continuously from cooler layer to cooler layer and thereby form continuous columns, and
- that each opening of one cooler layer is opposite a material section of an adjacent cooler layer, said material section extending away from one of the continuous columns, so that a coolant flow through an opening is possible only around or past another material section of an adjacent cooler layer.

- said first and second collection spaces being formed by first and second openings in said cooler layers,
- said flow paths are formed by structuring at least one area of the cooler layers as a screen,
- wherein the plurality of openings are made angled with two intersecting opening sections, wherein adjacent cooler layers adjoin one another such that the plurality of openings of adjacent cooler layers partially overlap, so that the plurality of openings of one cooler layer is opposite a material section or crosspieces between the plurality of openings of an adjacent cooler layer, so that a coolant flow through the plurality of openings is possible only around or past another material section of an adjacent cooler layer, and
- wherein material sections are structured as a screen remaining around the plurality of openings and overlap continuously from cooler layer to cooler layer and thereby form continuous columns, said columns being exposed to intensive flow of coolant all around and on all sides.
