Solution Overview
Problem
Optical modules face challenges in maintaining high precision optical output across a wide temperature range while minimizing power consumption and system size, particularly due to the inefficiencies in temperature adjustment and heat dissipation mechanisms.
Innovation Solution
The optical module incorporates a first base member with a red laser and a second base member with a laser emitting non-red light, each with a dedicated electronic cooling module, thermally separated to allow independent temperature adjustment, reducing power consumption and heat generation, and features a heat dissipation system that includes a heat sink and fan operation optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single electronic cooling module is used to cool both red laser and non-red laser, then device complexity is reduced, but temperature control precision deteriorates because red laser requires stricter temperature management
Solution Approach 1:
The cooling system is segmented into two independent electronic cooling modules: a first electronic cooling module dedicated to the red laser and a second electronic cooling module dedicated to the non-red laser. This segmentation allows each module to independently control the temperature of its respective laser, ensuring that the red laser receives the stricter temperature management it requires while the non-red laser is cooled separately, thus resolving the contradiction between device complexity and temperature control precision.
2Volume of moving object
If electronic cooling modules are placed close together to reduce system size, then compactness is improved, but heat dissipation efficiency deteriorates due to thermal interference
Solution Approach 1:
A heat dissipation structure is introduced as an intermediary component between the first electronic cooling module (cooling red laser) and the second electronic cooling module (cooling non-red laser). This heat dissipation structure acts as a thermal barrier that prevents heat from one laser from interfering with the cooling of the other laser, thereby maintaining heat dissipation efficiency while allowing the system to remain compact. The intermediary structure resolves the contradiction by enabling close placement of cooling modules without sacrificing thermal performance.
