`AMENDMENTSTO THE CLAIMS
`
`This listing of claims will replaceall prior versions andlistings of claimsin the
`
`application:
`
`1.
`
`(Currently amended) A cooling system for a heat-generating component, comprising:
`
`a double-sided chassis adapted to mount a pumpconfiguredto circulate a cooling liquid,
`
`the pump comprising a stator and an impeller, the impeller being positioned #-a-+eeess on the
`
`underside of the chassis and the stator being positioned on the upperside of the chassis and
`
`isolated from the cooling liquid;
`
`a reservoir adapted to pass the cooling liquid therethrough, the reservoir including:
`
`
`
`
`
`a pump chamber fermedbytherecess-andincluding the impeller and formed
`
`below the chassis, the pump chamber being defined byat least an impeller cover having one or
`
`more passages for the cooling liquid to pass through;
`
`a thermal exchange chamber formed below the pump chamberandvertically
`
`spaced apart from the pump chamber, the pump chamberandthe thermal exchange chamber
`
`being separate chambersthat are fluidly coupled together by the one or more passages; and
`
`a heat-exchanginginterface, the heat-exchanging interface forming a boundary
`
`wall of the thermal exchange chamber, and configured to be placed in thermal contact with a
`
`surface of the heat-generating component; and
`
`a heatradiator fluidly coupled to the reservoir and configured to dissipate heat from the
`
`cooling liquid.
