Solution Overview
Problem
In-vehicle display devices face heat dissipation challenges due to increased heat generation from components like ECUs and ICs, leading to potential damage from high temperatures and uneven temperature distribution.
Innovation Solution
A display device design incorporating a heat-conducting support unit that contacts heat-conducting vehicle components and an air flow path within the storage unit to enhance heat dissipation, merging exhaust air flows to increase circulation speed and improve heat release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If heat dissipation structures are added to the display device, then heat dissipation efficiency is improved, but device complexity increases
Solution Approach 1:
The patent merges the display device housing with the air conditioning system by integrating the storage unit (housing) with air intake and discharge ports. The housing simultaneously serves as both the display device enclosure and the air conditioning unit, eliminating the need for separate heat dissipation structures while maintaining effective heat dissipation through the integrated air flow paths.
2Temperature
If air flow paths are integrated into the housing, then heat dissipation is improved, but manufacturing complexity increases
Solution Approach 1:
The housing is designed with multi-functionality, serving simultaneously as the display device enclosure, the air conditioning unit, and the heat dissipation structure. The storage unit incorporates air intake and discharge ports that dual-purpose for both air conditioning operation and heat dissipation from the display device, eliminating the need for separate dedicated heat dissipation components and simplifying manufacturing.

Function Achieved in This Case
The solution effectively enhances heat dissipation efficiency, reducing the risk of damage from high temperatures and maintaining optimal operating conditions for in-vehicle display devices.
Implementation Method 1
a support unit formed of a heat-conducting material, and configured to support the display unit so that the display unit is fixed in the cabin of the vehicle. The support unit is arranged so as to be in contact with components made of a heat-conducting material and mounted on the vehicle.
Implementation Method 2
an air flow path within the storage unit to enhance heat dissipation, merging exhaust air flows to increase circulation speed and improve heat release.
Implementation Method 3
a confluence portion configured to merge a first exhaust air discharged from the air discharge port and a second exhaust air discharged from an air conditioner for a cabin of the vehicle through an air outlet arranged in the cabin. The confluence portion is defined such that a first flow direction in which the first exhaust air flows and a second flow direction in which the second exhaust air flows coincide with each other.
