Emergency Ventilator Blower Cooling via Conductive Housing Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Emergency ventilators face overheating issues due to friction and electrical resistance in their blower components, which can limit their portability and effectiveness.
Innovation Solution
The emergency ventilator incorporates a heat-conducting body made from light metal, non-ferrous metal, or plastic filled with thermally conductive materials to dissipate heat generated by the blower, ensuring efficient thermal conductivity and convection, thereby preventing overheating without increasing the device's weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If additional cooling structures are added to the blower, then heat dissipation is improved, but device weight increases
Solution Approach 1:
The patent combines the cooling function with the existing blower housing structure by integrating a heat-conducting body (aluminum or aluminum alloy) into the housing itself. This merging of structural and thermal management functions eliminates the need for separate cooling components, achieving effective heat dissipation while maintaining portability and avoiding additional weight.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution effectively manages heat dissipation, ensuring the ventilator remains portable and operational without the need for additional cooling structures, while maintaining mechanical stability and thermal conductivity.
Implementation Method 1
the blower housing can transfer heat generated in the blower to the heat conductor, at least by conduction, but possibly also by additional physical principles of heat transfer, such as radiation and convection
Implementation Method 2
The emergency ventilator can transfer the heat transferred from the blower housing to the heat conductor via its housing to the external environment of the emergency ventilator
