PrimeKey Solutions AB, S...

1. A security arrangement (10) adapted to improve heat dissipation from circuit board components (12, 14, 16, 18, 20) on a computer circuit board (22), wherein a plurality of said circuit components (12, 14, 16, 18, 20) are embedded in a security shield (5) formed by a potting on at least one surface of said circuit board (22) and thermally connected to at least one heat exchanger device (24), wherein said heat exchanger device (24) is located at a distance from said security shield (5), and that at least a plurality of said circuit components (12, 14, 16, 18, 20) are thermally connected with said at least one heat exchanger device (24) via at least one heat dissipating lead (32, 33, 34) to enhance cooling of said circuit board components (12, 14, 16, 18, 20), wherein said at least one heat dissipating lead (32, 33, 34) is formed as an elongated heat transferring member, having at least one part attached within said security shield (5) and another part thermally connected to said heat exchanger, wherein the at least one heat dissipating lead extends from within the potting to out of the potting.
