Abstract
A portable information handling system manages thermal energy presented at a keyboard with a hybrid support plate having a first portion of a first material and first thermal conductivity and a second material of a second thermal conductivity so that heat is presented in an even manner at the keyboard. For example, a keyboard support plate of a metal, such as steel, has a portion of liquid crystal polymer aligned with a central processing unit to impede heat transfer at the location of the central processing unit. In various embodiments, the liquid crystal polymer can include a carbon liquid crystal polymer and a delta liquid crystal polymer.
Claims20
An information handling system comprising:
- a housing;
- a processor disposed in the housing and operable to execute instructions that process information;
- a memory disposed in the housing and interfaced with the processor, the memory operable to store the instructions and information;
- and
- a keyboard coupled to the housing, the keyboard having plural keys biased out of the housing and configured to depress inward in response to an end user press, the plural keys disposed over a membrane having plural sensors to detect presses of the keys, the membrane supported by a support plate having a thickness of a first material having a first thermal conductivity in a first portion and a second material having a second thermal conductivity in a second portion, the second thermal conductivity less than the first thermal conductivity, the second portion aligned with the processor to avoid a hotspot at the keyboard from thermal energy of the processor.
(canceled)
A method for managing information handling system housing temperatures, the method comprising:
- forming a keyboard support of a thickness to have a first portion of a first material and first thermal conductivity and a second portion of a second material and a second thermal conductivity;
- coupling a membrane to the keyboard support, the membrane having plural sensors to detect key inputs;
- coupling plural keys over the membrane to assemble a keyboard that accepts end user presses as inputs and translates the end user presses to the membrane against the keyboard support;
- and
- coupling the keyboard to a portable housing with the second portion aligned with a predetermined thermal source within the portable housing.
A keyboard comprising:
- plural keys biased upward and configured to depress inward in response to an end user press;
- a membrane disposed under the plural keys and having plural sensors aligned with the plural keys to detect presses of the plural keys;
- a support plate disposed under the membrane and having a thickness of a first material having a first thermal conductivity in a first portion and a second material having a second thermal conductivity in a second portion, the second thermal conductivity less than the first thermal conductivity, the second portion aligned with a predetermined thermal source within a portable housing that couples to the keyboard.
