Abstract
A cooling apparatus for usage in an electronic system, a liquid loop heat exchanger body is configured for attachment to an exterior surface of an electronic system chassis.
Claims21
A cooling apparatus comprising:
- a tube extending in a loop interior to an electronic system chassis, through a chassis wall, and exterior to the chassis;
- and
- a liquid loop heat exchanger body comprising a parallel stack of closely-spaced plate fins enclosing and coupled to a portion of the loop external to the chassis and configured for attachment to an exterior surface of the chassis, wherein the tube exterior to the electronic system chassis further comprises:
- an inlet tube and an outlet tube coupled to the heat exchanger body;
- and at least one hinge coupled to at least one of the inlet tube and outlet tube enabling the heat exchanger body to be rotated away from the electronic system chassis for user and/or service access.
2 more elements
A liquid loop cooling system comprising:
- a tubing forming a loop that extends through an electronic system chassis interior to selectively apply cooling to interior system components and further exits the chassis to an exterior tubing segment exterior to the chassis;
- and
- a liquid loop heat exchanger comprising a parallel stack of plate fins exterior to the chassis and coupled to the exterior tubing segment, wherein the exterior tubing segment further comprises:
- an inlet tube and an outlet tube coupled to the heat exchanger;
- and at least one hinge coupled to the inlet tube and outlet tube enabling the heat exchanger to be rotated away from the electronic system chassis for user and/or service access.
2 more elements
An electronic system comprising:
- a chassis including airflow inlet and outlet vents, and fans capable of circulating air from the inlet vents to the outlet vents;
- a plurality of components mounted within the chassis and forming local heat sources;
- a tubing forming a loop that extends through the chassis interior to selectively apply cooling to the components and further exits the chassis to an exterior tubing segment exterior to the chassis;
- and
- a liquid loop heat exchanger comprising a parallel stack of planar plate fins exterior to the chassis, coupled to the exterior tubing segment, and arranged perpendicular to a planar surface of the chassis, at least one fan selectively positioned to drive air in an airflow pathway passing between the parallel planar plate fins in the heat exchanger;
- and at least one fan selectively positioned within the chassis, separated from the heat exchanger.
3 more elements
A method of configuring a liquid loop cooling system in an electronic system comprising:
- arranging a tubing in a loop extending through an electronic system chassis interior;
- passing the tubing from the chassis interior through a chassis wall to the chassis exterior;
- extending the tubing loop outside the electronic system chassis;
- mounting a liquid loop heat exchanger including a plurality of mutually parallel planar plate fins on the exterior of the chassis, the mutually planar parallel plate fins being coupled to the chassis exterior perpendicular to a chassis surface;
- and
- connecting the tubing loop outside the chassis to the liquid loop heat exchanger at a hinged connection, the tubing loop passing through and perpendicular to the mutually parallel planar plate fins;
- and configuring the hinged connection whereby the liquid loop heat exchanger is enabled to be rotated away from the electronic system chassis for user and/or service access.
