Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-power LED electric light sources face limitations in heat dissipation due to size constraints, leading to increased temperature and reduced power capacity, as conventional fan designs occupy valuable space and interfere with heat dissipation channels.
Innovation Solution
A heat dissipation device with radiator fans placed in an avoidance space between radiating fins, allowing airflow to flow from left to right, reducing channel height and interference, and enhancing heat radiation capacity by positioning fans off-center, thus increasing the available mounting surface area and overall heat dissipation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the radiator fan is arranged on the downward luminous LED module heat dissipation channel extending vertically downward, then the heat dissipation performance is improved, but the installation space is occupied and the lamp panel area is reduced
Solution Approach 1:
The patent changes the heat dissipation channel orientation from vertical downward to horizontal left-right direction, allowing the radiator fan to be arranged in the avoidance space without occupying the lamp panel area, thus resolving the contradiction between heat dissipation performance and available mounting area
Solution Approach 2:
The patent introduces an asymmetric design by positioning the radiator fan in the avoidance space on one side of the heat dissipation channel, creating unequal heat dissipation capacity between left and right sides, which is then corrected by additional design measures
2Power
If the LED lamp beads are arranged more tightly to increase power, then the power of electric light source is improved, but the temperature rise of LED lamp beads increases
Solution Approach 1:
By changing the heat dissipation channel to horizontal orientation, the patent creates sufficient space for effective heat dissipation, enabling tighter arrangement of LED lamp beads for higher power without causing excessive temperature rise
3Temperature
If the heat dissipation channel extends vertically downward, then the heat dissipation capacity is improved, but the height of heat dissipation channel increases and installation space is occupied
Solution Approach 1:
The patent transitions the heat dissipation channel from vertical orientation to horizontal orientation, reducing the height requirement and allowing the channel to be integrated within the planar structure of the electric light source, thus improving heat dissipation capacity without increasing installation height
