Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles equipped with electronic circuitry, such as CPUs and GPUs, face challenges in efficiently dissipating heat generated during operation, which can lead to reduced performance and increased passenger compartment temperatures.
Innovation Solution
A heat dissipation device comprising an enclosure, a heat sink, and a fan is designed for insertion into a vehicle's interior compartment aperture, positioning the heat sink and fan exteriorly while keeping the enclosure and electronic devices interiorly, allowing for efficient heat extraction and dissipation into the external environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If heat dissipation components are positioned inside the vehicle interior compartment, then the electronic devices can be cooled, but the air conditioning system load increases
Solution Approach 1:
The heat dissipation system extracts heat from electronic devices at the source, before it can enter the passenger compartment air. This prevents the air conditioning system from having to remove this heat load, thereby reducing its energy consumption and improving overall cooling efficiency.
Solution Approach 2:
The system converts the harmful heat generated by electronic devices into a manageable thermal flow that is directed externally. By providing a dedicated heat ejection pathway through the enclosure's heat sink and fan, the harmful heat is converted into a controlled thermal discharge that benefits the vehicle's thermal management without burdening the air conditioning system.
2Temperature
If heat dissipation components are positioned outside the vehicle, then heat is dissipated into the external environment, but the heat dissipation device complexity increases
Solution Approach 1:
The enclosure merges multiple functions into a single integrated structure: it houses the electronic devices, provides thermal management components (heat sink and fan), and serves as the interface for exterior heat dissipation. This consolidation improves heat dissipation effectiveness while managing device complexity through functional integration.
Solution Approach 2:
The enclosure serves multiple purposes simultaneously: it acts as a protective housing for electronic devices, a thermal management system with integrated heat sink and fan, and a structural component that interfaces with the vehicle body for exterior heat rejection. This multi-functionality achieves effective heat dissipation without proportionally increasing complexity.

Function Achieved in This Case
This configuration enhances cooling efficiency for electronic devices within vehicles, improving performance and passenger comfort by redirecting heat away from the interior compartment, thereby reducing the load on the vehicle's air conditioning system.
Implementation Method 1
a heat sink... extract heat from the electronic circuitry

AI summary
Provided are example systems for dissipating heat from vehicle-based data processing components. In an example implementation, a heat dissipation device includes a heat sink, an enclosure configured to receive a device including electronic circuitry, a fan, and a flange extending along a periphery of the enclosure and/or the heat sink. The heat dissipation device is configured for insertion into an aperture of a wall of an interior compartment of a vehicle, such that the flange is positioned against the wall, at least a portion of the enclosure is positioned within the interior compartment of the vehicle, and at least a portion of the heat sink and the fan are positioned along an exterior of the vehicle.
