Patent ID: 8351209

Claim:
A wireless network receiver, comprising: a heat-dissipating unit having at least one main heat-dissipating body and a front heat-dissipating body extended forward from the at least one main heat-dissipating body; a first substrate unit disposed on the heat-dissipating unit and contacting the heat-dissipating unit, wherein the first substrate unit includes at least one first function circuit board and a plurality of first function chips electrically connected to the at least one first function circuit board, and the at least one first function circuit board has an external circuit board extended forward from a front side thereof and disposed on the front heat-dissipating body; a second substrate unit electrically connected to the first substrate unit and contacting the heat-dissipating unit, wherein the second substrate unit includes at least one second function circuit board electrically connected to the at least one first function circuit board and a plurality of second function chips electrically connected to the at least one second function circuit board; an electrical connecting unit including an electrical connecting casing contacting the front heat-dissipating body and enveloping the front heat-dissipating body and the external circuit board; and a shell unit including a shell module for enveloping the heat-dissipating unit, the first substrate unit and the second substrate unit and selectively exposing or hiding the electrical connecting unit.
