Abstract:
1. An electronic device with improved heat dissipation properties comprising: a housing comprising a backside defining a backside plane and at least a first side orthogonal to the backside; a base circuit board positioned within the housing in a plane parallel to the backside plane and orthogonal to each of the housing first side and housing second side; a first cassette coupled to the base circuit board by a first cassette connector, the first cassette comprising: a first cassette printed circuit board in a plane parallel to the first side plane and orthogonal to the base circuit board; a first heat generating component coupled to the first cassette printed circuit board, the first heat generating component having a first thickness extending from the first cassette printed circuit board towards the housing first side; a second heat generating component coupled to the first cassette printed circuit board, the second heat generating component having a second thickness extending from the first cassette printed circuit board towards the housing first side, the second thickness being less than the first thickness; and a first cassette heat dissipation structure positioned between the first cassette printed circuit board and the housing first side, the first cassette heat dissipation side contacting each of the housing first side, the first heat generating component, and the second heat generating component.
