Projector Cooling Chamber Layout for Waterproof Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current projection mobile terminals face challenges in balancing heat dissipation and waterproof performance, often resulting in poor performance in one or both areas.
Innovation Solution
The mobile terminal incorporates a heat dissipate chamber with a thermally conductive heat dissipate block and a blower, which forms a heat dissipation sealing chamber, enhancing both heat dissipation and waterproofing by isolating the heat dissipate chamber from the main chamber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the radiator structure is optimized to improve heat dissipation performance, then heat dissipation is improved, but waterproof performance deteriorates
Solution Approach 1:
The mobile terminal is divided into two independent chambers: a heat dissipation chamber for the projector and a waterproof chamber for electronic components. This segmentation allows the heat dissipation structure to be optimized independently without compromising the waterproof integrity of the main body, resolving the contradiction between heat dissipation performance and waterproof performance
Solution Approach 2:
A partition wall with a through-hole acts as an intermediary between the heat dissipation chamber and waterproof chamber. The through-hole allows heat transfer from the projector to the cooling air while the partition wall itself maintains the waterproof barrier, enabling both heat dissipation and waterproof protection to coexist

Function Achieved in This Case
This design effectively balances heat dissipation and waterproof performance, ensuring that even if liquid enters the heat dissipate chamber, the internal electronic components remain unaffected, providing a safe and reliable solution.
Implementation Method 1
The heat dissipate block is thermally conductive and fixedly connected to the projector, and covered and fixed to the assembly opening of the heat dissipate chamber, the heat dissipate block is configured to absorb the heat generated by the projector during operation
Implementation Method 2
The blower is provided in the heat dissipate chamber and covered by the heat dissipate block, the blower is configured to cause air outside to enter the heat dissipate chamber through the air inlet passage and to be discharged through the air outlet passage
