Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing joint connectors face heat dissipation challenges due to heat accumulation in the housing, particularly when busbar terminals are press-fit and held in a separation wall, leading to reduced heat dissipation.
Innovation Solution
A joint connector design incorporating busbar terminals, a housing, and a heat dissipation plate that contacts the outer surface of the housing near the holding portion, with a heat dissipation plate featuring side and bottom surface corresponding portions to enhance heat transfer and dissipation, including grooves and hooks for secure mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If busbar terminals are press-fit and held in a separation wall in the housing, then the terminals are securely fixed, but heat dissipation is reduced due to heat accumulation in the housing
Solution Approach 1:
A heat dissipation plate is introduced as an intermediary component between the busbar terminals and the housing. The plate receives heat from the terminals through thermal conduction and dissipates it to the external environment, effectively mediating the heat transfer process and preventing heat accumulation in the housing while maintaining terminal fixation
2Temperature
If the heat dissipation plate covers the entire side surface, then heat dissipation area is maximized, but device complexity and manufacturing cost increase
Solution Approach 1:
The heat dissipation plate is designed with different functional regions: a larger first heat dissipation surface for primary heat dissipation, and a smaller second heat dissipation surface (side surface corresponding portion) for supplementary dissipation. This local differentiation optimizes heat dissipation effectiveness while controlling structural complexity and manufacturing cost
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 transfers heat from the busbar terminals to the heat dissipation plate, improving heat dissipation and preventing temperature increases in the busbar terminals, while allowing for optional removal of the heat dissipation plates to reduce weight and cost.
Implementation Method 1
Heat generated in the busbar terminal when the busbar terminal is energized is transferred first to the holding portion of the housing holding the busbar terminal and subsequently to the outer surface of the housing close to the holding portion of the housing
Implementation Method 2
heat dissipation can be improved by mounting the heat dissipation plate to contact the outer surface close to the holding portion
Implementation Method 3
heat dissipation can be improved by mounting the heat dissipation plate to contact the outer surface close to the holding portion
