Solution Overview
Problem
Existing image pickup apparatuses face challenges in efficiently cooling heat sources using fans, leading to increased component count and cost due to the need for multiple fans and complex duct configurations, which can result in uneven cooling and discomfort for users.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a single fan is provided in the apparatus that has the plurality of intake ports, then the number of components is reduced, but difference in ventilation resistance occurs in the air flow paths which disturbs efficient cooling of the heat sources
Solution Approach 1:
The air flow path is segmented into multiple independent ducts (first duct and second duct), each connected to a different heat generating element. Each duct has its own connection to the common exhaust port, allowing a single fan to effectively cool multiple heat sources by dividing the cooling paths while maintaining balanced air flow distribution.
2Device complexity
If the centrifugal fan is arranged on the way of a flow path (duct) and a direction of an intake port intersects with a direction of an exhaust port, then the duct shape is simplified, but the number of components that constitute the duct increases
Solution Approach 1:
Multiple ducts (first duct and second duct) are merged into a unified structure that shares a common exhaust port. The ducts are configured to extend in different directions from the fan and converge at the exhaust port, combining multiple cooling paths into an integrated system that reduces the total number of components while maintaining efficient air flow.
3Reliability
If multiple fans are provided for each intake port to take in outside air effectively, then cooling efficiency is improved, but the apparatus is enlarged and cost increases because the number of components increases
Solution Approach 1:
A single fan is designed to perform multiple cooling functions by connecting to multiple ducts that lead to different heat generating elements. The fan serves as a universal cooling source for the entire apparatus, replacing the need for multiple dedicated fans while maintaining effective cooling of all heat sources through the multi-duct configuration.

Function Achieved in This Case
This approach allows for efficient heat dissipation with reduced components, minimizing user discomfort and maintaining optical performance by ensuring uniform temperature distribution around the image pickup lens.
Implementation Method 1
forced air cooling using a fan is one of methods of discharging heat effectively. The forced air cooling cools the inside of the image pickup apparatus using air taken in from the outside of the image pickup apparatus with the fan.
Implementation Method 2
The forced air cooling cools the inside of the image pickup apparatus using air taken in from the outside of the image pickup apparatus with the fan. Then, the warmed air is discharged to the exterior of the image pickup apparatus.

AI summary
An electronic apparatus that is capable of cooling heat sources efficiently by taking in outside air through intake ports effectively while reducing the number of components. The electronic apparatus obtains an image signal corresponding to an optical image formed through an image pickup lens. A first heat generating element is implemented in a first substrate. A second heat generating element is implemented in a second substrate. A first duct is connected to the first heat generating element at a position nearer to an exhaust port formed in a housing of the electronic apparatus than a first blower that sends air to the first duct. A second duct is connected to the second heat generating element at a position nearer to the exhaust port than a second blower that sends air to the second duct.
