Patent ID: 8248785

Claim:
An electronic device, comprising: an enclosure defining a receiving space therein, at least one ventilating hole defined in the enclosure; at least one electronic component received in the receiving space of the enclosure; a heat sink; a thermal insulation member received in the receiving space of the enclosure, the thermal insulation member defining a heat dissipating passage therein, the heat dissipating passage communicating with the exterior via the at least one ventilating hole of the enclosure, and the heat sink received in the heat dissipating passage and thermally coupled to the at least one electronic component for dissipating heat from the at least one electronic component, wherein the heat dissipating passage is substantially thermally insulated from the part of the receiving space of the enclosure having the at least one electronic component by the thermal insulation member; and at least one base absorbing heat from the at least one electronic component and at least one heat pipe extending through the thermal insulation member, the at least one heat pipe comprising an evaporator section thermally contacting the at least one base and a condenser section thermally contacting the heat sink; wherein the thermal insulation member comprises a first plate and a pair of second plates extending from two opposite side edges of the first plate, and the first plate defines at least one engaging groove through which the at least one heat pipe extends; and wherein the at least one heat pipe is U-shaped, the evaporator section is parallel to the condenser section, an adiabatic section of the at least one heat pipe is located between the evaporator section and the condenser section, the adiabatic section is received in the at least one engaging groove, the evaporator section is located below the first plate, and the condenser section is located above the first plate.
