Abstract

An information handling system is disclosed. The information handling system comprises a chassis including a metal base, and a metal insulation layer, and a processing unit coupled to the chassis.

Claims

1. An information handling system, comprising:

a chassis comprising;

a metal base; and

a single thermal insulation layer consisting of a disordered-phase composition of a first metal and a second metal, wherein the thermal insulation layer comprises bismuth and selenium; and

a processing unit coupled to the chassis.

2. The information handling system of claim 1, wherein the thermal insulation layer comprises at least one element from the group of lithium, magnesium, aluminum, zinc, titanium, niobium, tantalum, vanadium, silicon, and germanium.

3. The information handling system of claim 1, wherein:

the first metal includes at least one element from the group of bismuth, lithium, magnesium, aluminum, zinc, titanium, niobium, tantalum, vanadium, silicon, and germanium; and

the second metal includes a ternary alloy.

4. The information handling system of claim 3, wherein the ternary alloy comprises one of the group of magnesium-silicon-tin, magnesium-zinc-manganese, iron-vanadium-aluminum, nickel-aluminum-chromium, bismuth-silver-aluminum, and titanium-aluminum-vanadium.

5. The information handling system of claim 1, wherein the thermal insulation layer is configured in a pattern corresponding at least to the location of the processing unit.

6. The information handling system of claim 1, wherein the chassis further comprises a reflective layer including an infrared radiation reflective material.

7. The information handling system of claim 6, wherein the infrared radiation reflective material includes silver.

8. The information handling system of claim 6, wherein the reflective layer is configured in a pattern corresponding at least to the location of the processing unit.

9. The information handling system of claim 1, wherein the chassis further comprises a thermally conductive layer configured in a pattern to route heat from a first location corresponding to the processing unit to a second location corresponding to a cooling device coupled to the chassis.
