Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooling systems for information handling systems, such as fans, generate noise and may not efficiently manage heat under high-performance conditions.
Innovation Solution
The ion emitter/collector blower cooling system uses an ion emitter and collector with an ionic driving circuit to create charged ions, generating airflow that helps to dissipate heat without the need for traditional fans, thereby reducing noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional fan-based cooling systems are used, then heat dissipation is achieved, but noise is generated
Solution Approach 1:
The patent replaces the mechanical fan-based cooling system with an ion-based cooling system. Ions are generated and accelerated to create a plasma wind that directly cools the processor, eliminating the need for mechanical moving parts and thus reducing noise while maintaining heat dissipation efficiency
Solution Approach 2:
The patent changes the physical state and properties of the cooling medium from gaseous air flow (mechanical) to ionized plasma flow (electrical). By ionizing gas molecules and accelerating them through electric fields, the system achieves cooling through a fundamentally different physical mechanism that does not rely on mechanical rotation
2Productivity
If high airflow rate is achieved for effective cooling, then heat dissipation improves, but pressure head increases requiring more power
Solution Approach 1:
The patent uses ionized gas (plasma) as the working fluid to create a pneumatic flow for cooling. The ions are accelerated through electric fields to generate a high-velocity plasma jet that achieves high airflow rates for effective heat dissipation while the low-pressure head design reduces the overall power requirements compared to traditional high-pressure fan systems

AI summary
An information handling system (IHS) includes an ion emitter/collector blower cooling system including an ion emitter and an ion collector, the ion emitter/collector blower system being placed at a location within a chassis of the IHS vertically lower than the hardware processor in the chassis. The IHS includes an ionic driving circuit operatively coupled to the ion emitter via a high voltage to ionize gases within the ion emitter/collector blower housing and create charged ions that generate an airflow along a voltage field to and through an ion collector. The IHS includes an air inlet vent located below the ion emitter/collector and formed in a back surface of the chassis of the IHS and an air exhaust vent located at an upper exhaust vent location above the ion collector within the chassis of the IHS so that the airflow is brought into the chassis of the IHS via the ion emitter/collector cooling system and out of the air exhaust vent where a location of the air inlet vent relative to the upper exhaust vent location of the air exhaust vent in the chassis of the IHS in a vertical orientation provides convection-enhanced airflow.
