Abstract

A main housing portion of a portable information handing system. The main housing portion includes: a top cover portion; a bottom cover portion; and, an internal air intake ducting system, the internal air intake ducting system comprising a fan and a thermal channeling component thermally coupled to the fan, the thermal channeling component extending from an interior of a side of the bottom cover portion to the fan, the thermal channeling component and the bottom cover portion defining an air channel between the side of the bottom cover portion and the fan.

First claim

What is claimed is:

1. A main housing portion of a portable information handing system, comprising:
a top cover portion;
a bottom cover portion; and,
an internal air intake ducting system, the internal air intake ducting system comprising a fan and a thermal channeling component thermally coupled to the fan, the thermal channeling component extending from an interior of a side of the bottom cover portion to the fan, the thermal channeling component and the bottom cover portion defining an air channel between the side of the bottom cover portion and the fan, the thermal channeling component being affixed to an internal surface of the side of the bottom cover portion; and wherein
providing the air channel between the side of the bottom cover portion and the fan provides a thermal venting solution that does not rely on one or both of bottom venting and thermal feet.

2. The main housing portion of claim 1 , wherein:
the thermal channeling component is thermally coupled to the fan via a gasket.

3. The main housing portion of claim 1 , wherein:
the thermal channeling component is thermally coupled to the fan via a fan thermal channeling component mounting portion.

4. The main housing portion of claim 1 , wherein:
the thermal channeling component comprises a step portion, the step portion providing a taller air channel along a portion of the air channel between the side of the bottom cover and the fan.

5. The main housing portion of claim 4 , wherein:
the taller air channel is proximate with the fan.

6. The main housing portion of claim 1 , wherein:
the bottom cover comprises an angled side wall demarcation portion, the angled side wall demarcation portion extending downwardly from a front of the main housing portion to a rear of the main housing portion; and,
an air intake is integrated into the angled side wall demarcation portion, the air intake extending downwardly from the front of the main housing portion to the rear of the main housing portion along the angled side wall demarcation portion.

7. An information handling system comprising:
a processor;
a data bus coupled to the processor; and
an information handling system chassis housing, the housing comprising
a base chassis, the base chassis housing the processor, the base chassis comprising
a top cover portion;
a bottom cover portion; and,
an internal air intake ducting system, the internal air intake ducting system comprising a fan and a thermal channeling component thermally coupled to the fan, the thermal channeling component extending from an interior of a side of the bottom cover portion to the fan, the thermal channeling component and the bottom cover portion defining an air channel between the side of the bottom cover portion and the fan, the thermal channeling component being affixed to an internal surface of the side of the bottom cover portion; and wherein
providing the air channel between the side of the bottom cover portion and the fan provides a thermal venting solution that does not rely on one or both of bottom venting and thermal feet.

8. The information handling system of claim 7 , wherein:
the thermal channeling component is thermally coupled to the fan via a gasket.

9. The information handling system of claim 7 , wherein:
the thermal channeling component is thermally coupled to the fan via a fan thermal channeling component mounting portion.

10. The information handling system of claim 7 , wherein:
the thermal channeling component comprises a step portion, the step portion providing a taller air channel along a portion of the air channel between the side of the bottom cover and the fan.

11. The information handling system of claim 10 , wherein:
the taller air channel is proximate with the fan.

12. The information handling system of claim 7 , wherein:
the bottom cover comprises an angled side wall demarcation portion, the angled side wall demarcation portion extending downwardly from a front of the main housing portion to a rear of the main housing portion; and,
an air intake is integrated into the angled side wall demarcation portion, the air intake extending downwardly from the front of the main housing portion to the rear of the main housing portion along the angled side wall demarcation portion.
