Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing heat dissipation systems for vehicle controllers, which use heat pipes disposed vertically, result in increased space occupation and inefficiencies in heat dissipation due to the closed box shape of the controllers.
Innovation Solution
A vehicle controller heat dissipation module is introduced, featuring a horizontal heat pipe, heat dissipation fins, a first fan for air intake, and a second fan for air discharge, all designed to maintain a compact size while ensuring effective heat dissipation and preventing external moisture ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heat pipe is disposed vertically in the controller, then heat dissipation is achieved, but the space occupied by the controller increases greatly
Solution Approach 1:
The patent inverts the conventional vertical heat pipe arrangement by disposing the heat pipe horizontally within the controller. This inversion allows the heat dissipation function to be maintained while significantly reducing the vertical space occupation, thereby solving the contradiction between heat dissipation efficiency and controller size.
Solution Approach 2:
The patent transitions from a vertical (one-dimensional) heat pipe arrangement to a horizontal (another dimension) configuration. This dimensional change enables the heat pipe to dissipate heat effectively while occupying less vertical space, thus resolving the conflict between heat dissipation performance and compact controller dimensions.
2Reliability
If the controller is formed in a closed box shape to prevent foreign matter ingress, then protection is improved, but heat dissipation efficiency deteriorates
Solution Approach 1:
The patent introduces a heat dissipation fin as an intermediary component between the heat pipe and the external environment. The fin extends outward from the heat pipe through the controller housing, providing a thermal pathway for heat dissipation while the housing itself maintains its protective closed-box structure against foreign matter ingress.
Solution Approach 2:
The patent employs a heat dissipation fin structure that can be disposed in various configurations (including bent and wave shapes) to optimize heat transfer while maintaining the integrity of the closed controller housing. The fin acts as a flexible thermal pathway that does not compromise the protective enclosure.
3Temperature
If heat dissipation fins are added to improve heat dissipation, then temperature control is improved, but device complexity increases
Solution Approach 1:
The patent optimizes the heat dissipation fin parameters including its shape (bent, wave, or straight configurations), surface area, and thermal conductivity. By carefully selecting and adjusting these parameters, the patent achieves effective heat dissipation while maintaining a relatively simple structural design that does not significantly increase device complexity.
