Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional turbo blower cooling systems face inefficiencies due to high power consumption and inadequate cooling of internal components, leading to reduced lifespan and durability, as they primarily rely on air intake or low-efficiency air blowing methods, which fail to provide thermal balance.
Innovation Solution
A direct drive-type turbo blower cooling structure featuring multiple holes along the outer diameter of a motor casing, coil part, and rotor, utilizing a cooling fan to enhance cooling efficiency by maximizing air contact area and ensuring uniform cooling of stator, coil, and bearing components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a cooling fan blows a large amount of air through the motor casing, then the cooling coverage is increased, but the cooling efficiency is reduced and power consumption increases
Solution Approach 1:
The motor casing is divided into multiple cooling zones with separate air inlets and cooling passages for the stator, rotor, and bearing housing, allowing targeted cooling of each component rather than uniform blowing across the entire interior
Solution Approach 2:
Different regions of the motor casing are equipped with specific cooling features: air inlet holes in the stator core, cooling passages in the rotor, and air outlets positioned near bearing housings, ensuring each component receives appropriate cooling based on its thermal characteristics
2Temperature
If air is blown by considerable pressure using a cooling fan, then cooling is forced onto components, but the power consumption increases and cooling efficiency decreases
Solution Approach 1:
The cooling system utilizes the dynamic rotation of the impeller to generate centrifugal force that drives air flow through the cooling passages, replacing the need for high-pressure forced air from a cooling fan with a more energy-efficient dynamic flow mechanism
Solution Approach 2:
The impeller's rotation during normal operation naturally generates air flow that cools the motor components, allowing the system to cool itself without requiring additional high-power cooling equipment
3Adaptability or versatility
If the cooling system is closely interlocked with the impeller design, then the cooling structure adapts to the impeller shape, but the design freedom is restricted and sensitivity to impeller changes increases
Solution Approach 1:
The cooling passages and air flow paths are designed as independent modular features that can be applied to various impeller designs without requiring custom integration, allowing the same cooling structure to work with different impeller shapes and sizes
