Abstract

An electronic device console includes a console body that houses a chip package, and a duct extending from the console body. An interior volume of the duct is in fluid communication with an interior volume of the console body. A first vent is at a distal end of the duct. A second vent is in a wall of the console body. The console may be oriented in a first orientation and a second orientation. The duct functions as a chimney for natural convection cooling of the chip package when the console is oriented in the first orientation. The console body functions as a chimney for natural convection cooling of the chip package when the console is oriented in the second orientation.

First claim

What is claimed:

1. An electronic device console, comprising:
a console body that houses a chip package;
a duct extending from the console body, wherein an interior volume of the duct is in fluid communication with an interior volume of the console body;
a first vent at a distal end of the duct; and
a second vent in a wall of the console body;
wherein the electronic device console is structured and arranged to be oriented in a first orientation and a second orientation;
the duct functions as a chimney for natural convection cooling of the chip package when the electronic device console is oriented in the first orientation;
the console body functions as a chimney for natural convection cooling of the chip package when the electronic device console is oriented in the second orientation; and
the electronic device console comprises a plurality of feet structured and arranged to support the electronic device console on a surface in the first orientation and the second orientation,
wherein the electronic device comprises a slide mechanism positioned at a top orientation of the console body such that a proximate end of the duct is moveable into the console body through the slide mechanism that allows translational movement of the duct relative to the console body when the electronic device console is oriented in the first orientation, and
the slide mechanism allows a portion of the duct to be moved within the console body.

2. The electronic device console of claim 1 , wherein the electronic device console is devoid of a fan.

3. The electronic device console of claim 1 , wherein a length of the duct is greater than a width of the duct.

4. The electronic device console of claim 1 , wherein:
the first vent is an outlet and the second vent is an inlet in the first orientation; and
the first vent is an inlet and the second vent is an outlet in the second orientation.

5. The electronic device console of claim 1 , wherein:
the first vent is vertically aligned with the chip package in the first orientation; and
the second vent is vertically aligned with the chip package in the second orientation.

6. The electronic device console of claim 1 , wherein the chip package comprises: a chip, a printed circuit board, a lid, and a heat sink.

7. The electronic device console of claim 1 , wherein:
the electronic device console is a gaming console;
the gaming console comprises a system structured and arranged to receive a disc; and
the chip package comprises a gaming processor that executes a gaming application based on data obtained from the disc.

8. The electronic device console of claim 1 , wherein a length of the duct is adjustable.

9. The electronic device console of claim 1 , wherein a length of the duct outside of the console body is less than an extended length of the duct.

10. The electronic device console of claim 9 , wherein the electronic device console comprises a fan to supplement convection cooling of the chip package.

11. An electronic device console, comprising:
a console body that houses a chip package;
a duct connected to the console body, wherein an interior volume of the duct is in fluid communication with an interior volume of the console body;
a first vent at a distal end of the duct that places the interior volume of the duct in fluid communication with an ambient environment outside the electronic device console; and
a second vent in a wall at a lateral side of the console body that places the interior volume of the console body in fluid communication with the ambient environment;
at least one additional vent at a front side of the console body;
wherein the electronic device console is structured and arranged to be oriented in a first orientation and a second orientation;
the chip package is cooled via natural convection cooling without using a fan that is inside or attached to the electronic device console;
the duct provides a first chimney effect to the natural convection cooling of the chip package when the electronic device console is oriented in the first orientation;
the console body provides a second chimney effect to the natural convection cooling of the chip package when the electronic device console is oriented in the second orientation;
the electronic device console comprises a plurality of feet structured and arranged to support the electronic device console on a bottom surface and another lateral side in the first orientation and the second orientation; and
the electronic device further comprises a slide mechanism positioned at a top of the console body and which allows translational movement of the duct relative to the console body when the electronic device console is oriented in the first orientation such that a proximate end of the duct is moveable into the console body through the slide mechanism,
wherein
the first vent, the second vent, and the at least one additional vent comprises an opening that has an adjustable size, and
the chip package comprises:
a printed circuit board (PCB) which is coupled to a substrate through electrically conductive leads,
the substrate is joined to a die through solder bumps,
the die is connected to a first thermal interface material (TIM),
the first TIM is connected to a lid which is connected to a second TIM, and
the second TIM is connected to a heat sink to enhance heat transfer away from the die.

12. The electronic device console of claim 11 , wherein:
in the first orientation, the first vent is an outlet and the second vent is an inlet of a first flow path of the natural convection cooling; and
in the second orientation, the first vent is an inlet and the second vent is an outlet of a second flow path of the natural convection cooling.

13. The electronic device console of claim 11 , wherein:
the first orientation is horizontal; and
the second orientation is vertical.

14. The electronic device console of claim 11 , wherein:
the first vent is vertically aligned with the chip package in the first orientation; and
the second vent is vertically aligned with the chip package in the second orientation.

15. The electronic device console of claim 11 , wherein a length of the duct is adjustable.

16. The electronic device console of claim 11 , wherein the at least one additional vent comprises a louvered design.

17. The electronic device console of claim 11 , wherein the first TIM and the second TIM comprises elastomer.

18. The electronic device console of claim 17 , wherein the solder bumps comprise controlled collapse chip connection (C4) solder bumps which are encapsulated in an underfill material.
