Spinning Reel Spool Radiator for Drag Mechanism Heat Dissipation
Solution Overview
Problem
Existing spinning reels inadequately regulate temperature rises in drag mechanisms, leading to reduced performance due to indirect heat dissipation methods.
Innovation Solution
A spinning reel spool design incorporating a radiator in contact with the drag mechanism, which rotates with respect to the spool body or shaft to directly dissipate heat, and a heat discharger to guide internal heat radially outward, enhancing temperature regulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If air in the heat dissipating space is discharged out of the spool body to regulate temperature rise, then temperature regulation is achieved, but heat dissipation effectiveness is insufficient
Solution Approach 1:
A radiator is introduced as an intermediary component between the drag mechanism and the external environment. The radiator absorbs heat from the drag mechanism through thermal conduction and dissipates it to the surrounding air, enhancing heat transfer efficiency without requiring direct exposure of the drag mechanism to external airflow.
Solution Approach 2:
The heat dissipation function is extended from one-dimensional air discharge to three-dimensional space by positioning the radiator to expose multiple surfaces (radial and axial directions) to the surrounding environment, increasing the effective heat dissipation area and improving thermal management effectiveness.
2Loss of energy
If a radiator is added to directly dissipate heat from the drag mechanism, then heat dissipation effectiveness is improved, but device complexity increases
Solution Approach 1:
The radiator is integrated with the spool body as a unified structure rather than being a separate component. The radiator forms part of the spool's internal architecture, combining the spool body's structural function with the radiator's heat dissipation function, thereby improving thermal management without proportionally increasing device complexity.
Solution Approach 2:
The spool body is designed to serve multiple functions: it provides structural support for the drag mechanism, contains the radiator, and acts as part of the heat dissipation system itself. This multi-functionality reduces the need for additional dedicated components and simplifies the overall device structure.
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 effectively regulates temperature rises in the drag mechanism, ensuring optimal performance by direct heat dissipation and improved heat management.
Implementation Method 1
The radiator rotates with respect to one of the spool body or the spool shaft, and does not rotate with respect to the other one of the spool body or the spool shaft... the radiator in contact with the drag mechanism, then dissipates heat generated in the drag mechanism
Implementation Method 2
The radiator is arranged in the spool body and is in contact with the drag mechanism... the radiator in contact with the drag mechanism, then dissipates heat generated in the drag mechanism

AI summary
The present invention relates to a spool 4 for a spinning reel being mountable on a spool shaft 15. The spool 4 includes a spool body 42 that rotates with respect to the spool shaft 15. The spool 4 also includes a drag mechanism 43 between the spool body 42 and the spool shaft 15 to apply a braking force against a rotation of the spool body 42. The spool 4 further includes a radiator 44 in the spool body 42 and in contact with the drag mechanism 43. The radiator 44 rotates with respect to one of the spool body 42 or the spool shaft 15. The radiator 44 does not rotate with respect to the other one of the spool body 42 or the spool shaft 15. The invention further relates to a spinning reel comprising such a spool 4.
