Two-compartment AC adaptor
First Claim
Patent Images
1. An external AC power adaptor, comprising:
- a housing defining a first and second compartment, wherein power circuitry for converting an AC input to a DC output is disposed within the first compartment;
an opening formed in the housing proximate the second compartment; and
a heat transfer plate disposed between the first and second compartments, wherein the opening and heat transfer plate facilitate air flow cooling of the adaptor without air flowing through the first compartment.

Abstract
An external AC power adaptor having an additional compartment for cooling. The adaptor has a housing that defines a first compartment having power circuitry for converting an AC input to a DC output and a second compartment that has an opening formed in the adaptor housing. A heat transfer plate is disposed between the first and second compartments.

12. An external AC power adaptor, comprising:
-
a housing defining a first and second compartment, wherein power circuitry for converting an AC input to a DC output is disposed within the first compartment; a first and second opening defined by the housing and proximate the second compartment; a heat transfer plate disposed substantially between the first and second compartments, wherein the heat transfer plate is operatively coupled to the housing to enclose the first compartment and is thermally coupled to the power circuitry; and a fan for moving air into the second compartment from the first opening, across the heat transfer plate and out of the second compartment through the second opening, wherein the first and second openings, heat transfer plate and the fan facilitate air flow cooling of the adaptor without air flowing through the first compartment. - View Dependent Claims (13, 14, 15)

16. An apparatus comprising:
-
an external AC power adaptor having a cooling compartment formed within the adaptor, wherein a portion of the cooling compartment is defined by a heat transfer plate that is thermally coupled to power circuitry of the adaptor contained within a power circuitry compartment; and a fan for forcing air across the heat transfer plate through the cooling compartment to cool the adaptor without air flowing through the power circuitry compartment. - View Dependent Claims (17, 18, 19, 20)
