Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing light source devices in projectors have inefficient cooling mechanisms, leading to reduced lifespan and performance of solid-state light sources due to inadequate circulation of cooling gas, resulting in suboptimal cooling efficiency.
Innovation Solution
A light source device configuration featuring a heat dissipation portion with plate-like bodies, a connecting portion, and a shielding portion that directs cooling gas to the heat receiving portion at a shortest distance, ensuring efficient heat transfer and circulation, thereby increasing the cooling efficiency and lifespan of the light source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cooling gas is sent to the heat dissipation portion without shielding, then the cooling gas circulates through the heat dissipation portion, but the cooling efficiency is reduced because cooling gas is discharged through between fins without circulating to the light source portion
Solution Approach 1:
The shielding portion acts as an intermediary element that intercepts and redirects the cooling gas flow. It prevents the cooling gas from being discharged through the fins and instead guides it to circulate through the heat dissipation portion, ensuring effective heat removal from the light source portion while maintaining energy efficiency of the cooling system
2Area of stationary object
If the heat dissipation portion is designed with plate-like bodies extending along a plane, then the heat dissipation area is increased, but the cooling gas circulation path becomes complex and efficiency decreases
Solution Approach 1:
The heat dissipation portion is segmented into multiple plate-like bodies arranged in a specific pattern. This segmentation creates multiple parallel flow paths for the cooling gas, distributing the flow evenly across the heat dissipation area while maintaining relatively simple circulation paths. The plate-like structures divide the cooling gas flow into manageable streams that can efficiently traverse the heat dissipation surfaces
