One describes an electronic device cabinet (1) comprising a housing (2) and a printed-circuit board (3), the printed-circuit board (3) being positioned in the internal area of the housing (2) and defining a dissipation chamber (4'). The chamber (4') is formed between a first surface (9) of the printed-circuit board (3) and a first dissipating surface (11) of a dissipation board (10), said board (10) being fitted into the housing (2) of the cabinet. The board (3) comprises at least one electronic component (5a) positioned in the dissipation chamber (4'). The chamber (4') further comprising a filler (7), the filler (7) keeping direct contact with a perimeter of the electronic component (5a), with parts of the first surface (9) of the printed-circuit board (3), with the tracks of the printed-circuit board (3) and with parts of the first dissipating surface (11) of the dissipation board (10), the cabinet (1) being configured so that a second dissipating surface (12) of the board (1) opposite the first dissipating surface (11) is in direct contact with the external environment surrounding the cabinet (1). On further describes a dissipation board. |
