1. A liquid cooling system for cooling a heat-generating component of a computer, comprising:

  • a pump chamber housing an impeller and defined at least in part by an impeller cover and a double-sided chassis, the impeller being positioned on one side of the chassis and a stator of the pump is positioned on an opposite side of the chassis, wherein the pump chamber includes;

    an inlet defined by the impeller cover positioned below a center of the impeller configured to enable a cooling liquid to flow into the center of the pump chamber;

    an outlet defined by the impeller cover positioned tangentially to the circumference of the impeller;

    a thermal exchange chamber disposed between the pump chamber and the heat-generating component when the system is installed on the heat-generating component;

    a heat-exchanging interface forming a boundary wall of the thermal exchange chamber, the heat-exchanging interface has an outer surface configured to be placed in thermal contact with a surface of the heat-generating component and an inner surface that defines a plurality of channels that direct the flow of the cooling liquid within the thermal exchange chamber;

    a heat radiator adapted to pass the cooling liquid therethrough, the heat radiator being fluidly coupled to the pump chamber and the thermal exchange chamber via fluid conduits, the heat radiator being configured to dissipate heat from the cooling liquid;

    a first passage fluidly coupling the pump chamber and the thermal exchange chamber, wherein the first passage directs the cooling liquid from the outlet of the pump chamber into the thermal exchange chamber between a first end and a second end of the thermal exchanger chamber.
