Abstract

Portable devices, as notebook, laptop, smart-phone require high performance from one side and very light weight and small size from another. High power consumption dissipation and missing fan result in long operation of AP IC at high temperature and low battery life.

Abstract

Portable devices, as notebook, laptop, smart-phone require high performance from one side and very light weight and small size from another. High power consumption dissipation and missing fan result in long operation of AP IC at high temperature and low battery life.

Introduction

Low power consumption and thus longer battery life is one of the most critical parameters of portable devices as notebooks, smartphones, etc. Since processors in these products are very fast, it use fast process, that coming with high static current, that is increasing significantly with increasing temperature. For that reason keeping processor at lower temperature helps to reduce power consumption. Usually it’s done with fans and/or heavy radiators. Both solutions are not suitable for portable devices, that should be small and light.

Proposed solution

Ø  Proposal is to use special keyboard with small air pump on each keypad. Pressing of any key pad will cause pumping of ambient air into case, that will create air flow, cooling devices inside the case.

Ø  The same pump can play role of spring, that is placed in each key pad to bring it back after pressing.

Ø  Fig1 shows example of button implementation. Fig2 shows the way air is pumped into product, generating airflow
