Solution Overview
Problem
The existing projector configurations face challenges in efficiently conducting heat outside sealed structures using heat pipes, which limits the degree of freedom in arranging cooling components and reduces the effectiveness of heat dissipation, especially when the cooling target generates a large amount of heat.
Innovation Solution
The projector employs a triple circulation channel system where a gas (first fluid) circulates inside a sealed space to conduct heat to a liquid (second fluid) that is then cooled and radiates heat to another liquid (third fluid) outside the sealed space, utilizing a heat exchanger and thermoelectric conversion elements to enhance heat transfer efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If heat pipe is used to conduct heat from inside sealed structure to outside, then heat transfer is achieved, but the degree of freedom in arranging cooling components is reduced and heat dissipation effectiveness decreases when cooling target generates large amount of heat
Solution Approach 1:
The cooling system is divided into two independent circulation channels: a first circulation channel inside the sealed structure and a second circulation channel outside the sealed structure. This segmentation allows each channel to be arranged independently, increasing the degree of freedom in component placement while maintaining effective heat dissipation through separate fluid circulation paths.
Solution Approach 2:
A heat exchanger serves as an intermediary device between the first circulation channel (inside sealed structure) and the second circulation channel (outside sealed structure). The heat exchanger enables heat transfer from the cooling target inside the sealed structure to the circulating fluid outside, eliminating the need for heat pipes and providing flexible component arrangement.
2Temperature
If large heat receiving member and heat radiation member are used to efficiently conduct heat, then heat dissipation is improved, but the degree of freedom in arrangement is reduced
Solution Approach 1:
The invention uses circulating fluids (gas in first channel, liquid in second channel) to transfer heat instead of relying on large solid heat receiving and radiation members. The fluid circulation system provides efficient heat conduction while allowing flexible arrangement of compact heat exchanger components, thereby maintaining both heat dissipation effectiveness and arrangement freedom.
