Projector Cooling Device with Sealed Protrusion for Dust-Proof Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projector cooling systems compromise dust-proofness to effectively cool internal heat sources, as heat sinks extending outside the case degrade the dust-proof sealing and lead to inefficient heat transfer.
Innovation Solution
A cooling device with a fixing member, body, and internal case that includes a protrusion allowing the fixing member to pass through, maintaining dust-proofness while enabling effective heat dissipation through a sealed light source unit configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heat sink is extended outside the case to cool internal heat sources, then cooling efficiency is improved, but dust-proofness of the case deteriorates
Solution Approach 1:
The invention divides the heat dissipation function into two segments: an internal heat sink within the sealed case and an external protrusion extending outside the case. The internal heat sink receives heat from the light source, while the external protrusion dissipates heat to the environment. This segmentation allows the case to remain sealed for dust-proofness while achieving effective cooling through the external protrusion portion.
2Object-affected harmful factors
If the case is tightly sealed to prevent dust entry, then dust-proofness is improved, but heat dissipation capability worsens
Solution Approach 1:
The invention implements a nested structure where the internal case containing the light source and internal heat sink is positioned within the outer case. The internal case has a through-hole allowing the protrusion to extend outward. This nesting arrangement enables the sealed internal case to protect components from dust while the external protrusion provides heat dissipation pathways to the external environment.

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 cools internal heat sources within the projector while maintaining dust-proofness by using a sealed light source unit with a protrusion and sealing member, enhancing both cooling efficiency and dust-proof integrity.
Implementation Method 1
Heat of the semiconductor light-emitting device is transferred to fins of the heat sink
