Projector Intake Fan Layout for Cooling Detachable Wireless Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projectors face challenges in effectively cooling detachable wireless devices like SMPs, leading to potential operation failures due to heat buildup, while adding separate cooling devices increases cost and size.
Innovation Solution
A projector design with a partitioned enclosure featuring a first housing section for the wireless device and a second housing section for other heat sources, utilizing an intake fan to efficiently cool both by directing an air current from outside, with the device positioned on the inflow side and other components on the outflow side, and incorporating a dustproof filter to prevent dust intrusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate cooling device is provided for cooling connected equipment, then cooling effectiveness is improved, but device size increases
Solution Approach 1:
The single fan is designed to perform multiple cooling functions simultaneously - cooling both the connected equipment in the second housing section and the first cooling target in the first housing section. The fan creates a unified air current that flows through both sections via the vent hole, eliminating the need for separate cooling devices while maintaining effective cooling for all components.
Solution Approach 2:
The patent merges the cooling functions for different components into a single integrated cooling system. The first housing section and second housing section are connected through a vent hole, allowing a single fan to circulate air through both sections and cool multiple targets simultaneously, thereby reducing overall device size while maintaining cooling effectiveness.
2Volume of stationary object
If exhaust air is used to cool connected equipment, then device size is reduced, but cooling effectiveness deteriorates
Solution Approach 1:
The housing is segmented into a first housing section and a second housing section that are partitioned but connected via a vent hole. This segmentation allows the single fan to create distinct airflow paths - fresh air enters the second housing section to cool the connected equipment, while the first housing section is cooled by air flowing through the vent hole, ensuring both sections receive adequate cooling without requiring separate fans.
3Reliability
If multiple cooling devices are provided, then cooling reliability is improved, but device complexity increases
Solution Approach 1:
A single fan is designed to perform multiple cooling functions simultaneously - cooling both the connected equipment in the second housing section and the first cooling target in the first housing section. The fan creates a unified air current that flows through both sections via the vent hole, eliminating the need for separate cooling devices while maintaining effective cooling for all components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Efficient cooling of both the wireless device and other heat sources is achieved without increasing projector size, preventing operation failures and maintaining appearance, while reducing noise and cost by using a single intake fan and dustproof filter.
Implementation Method 1
an intake fan that cools both the wireless device and other heat sources with an air current it sucks from outside the enclosure

AI summary
A light source device includes an enclosure including a first housing part housing a first cooling target and a second housing part housing a second cooling target, the first cooling target being a terminal radiating heat and detachably housed in the first housing; and a first fan housed in the enclosure and cooling the first cooling target and the second cooling target by supplying an air current sucked from an outside of the enclosure to the first housing part and the second housing part in order. The first housing part is located on an inflow side of the air current with respect to the first fan. The second housing part is located on an outflow side of the air current with respect to the first fan.
