Abstract: The present invention pertains to a clamping element for holding electronic boards inserted in parallel to one another into an electronic rack. The arrangement removes waste heat from the electronic boards to the rack housing by heat conduction and via heat exchangers. A clamping element is proposed for this purpose, which substantially reduces the thermal resistance and consequently the temperature difference caused by heat conduction between the electronic board and the housing rack, and which also permits variable, defined adjustable clamping forces, and which is designed as an optical clamping control indicator.
