Screw-Driven Fan Cooling for Low-Complexity Screw Nut Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional screw cooling technologies are complex and costly to manufacture, and their use of cooling liquids can lead to environmental contamination due to potential overflow issues.
Innovation Solution
A screw-driven fan device is designed with a screw, screw nut, and connecting unit, where the screw's rotation drives a fan with a rotary axle and blades, utilizing airflow for heat dissipation without additional power or liquid cooling, simplifying the design and eliminating liquid overflow risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If cooling circulation paths are formed on the screw and screw nut seat, then cooling effect is achieved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent combines the cooling function with the existing screw and screw nut structure by integrating cooling passages into these components. The cooling passage in the screw communicates with the cooling passage in the screw nut seat, forming an integrated cooling system that achieves cooling effect without adding separate cooling apparatus, thereby reducing manufacturing complexity while maintaining effective heat dissipation
2Temperature
If cooling liquid is used for cooling, then heat dissipation is effective, but environmental pollution risk increases due to potential overflow
Solution Approach 1:
The patent replaces the conventional cooling liquid-based cooling system with an air cooling system. Air is introduced into the cooling passage through an air inlet and blown by a fan to directly cool the screw and screw nut. This substitution eliminates the use of cooling liquid entirely, achieving effective heat dissipation while completely avoiding the environmental pollution risk associated with cooling liquid overflow
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
The solution reduces manufacturing complexity and cost while providing effective heat dissipation without liquid contamination, using natural air circulation to efficiently dissipate heat from the screw nut.
Implementation Method 1
the fan provides a cooling mechanism... heat can be greatly dissipated from the screw nut... using natural air circulation to efficiently dissipate heat
Implementation Method 2
When the screw rotates, the coordination of the flange and the groove causes the fan rotates simultaneously

AI summary
A screw-driven fan device includes a screw, a screw nut, a fan, and a connecting unit. An external edge of the screw has a rolling groove formed thereon and a groove formed alternately with the rolling groove. The screw nut, disposed on the screw, has a linking portion located on one end of the screw nut. The fan has a rotary axle with a hole formed thereon for screw passing through. The fan further has blades surrounding the rotary axle. The hole has a flange formed on an interior side thereof, and the flange is engaged with the groove. When the screw rotates, the coordination of the flange and the groove causes the fan rotates simultaneously. The connecting unit has one side mounted on the linking portion of the screw nut. The connecting unit has a space therein such that the fan can be placed in the space, thereby the fan and the screw nut move together.
