Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-power electric vehicle systems require advanced heat-dissipating mechanisms due to increased temperatures, but existing electric equipment cases with air intakes and exhausts are vulnerable to water and dust ingress, potentially damaging components.
Innovation Solution
A car electric equipment case module with a housing, covering structure, and fan, featuring an air channel and ventilators, where the covering structure connects to the housing to form a gap that allows air flow for heat dissipation while preventing external moisture and dust from entering through the ventilators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If air intakes and exhausts are configured on the electric equipment case for heat dissipation, then heat dissipation performance is improved, but water-proof and dust-proof protection deteriorates
Solution Approach 1:
The patent divides the case structure into multiple segments: the main case body, the covering structure with block walls, and the air channel system. This segmentation allows the air intake and exhaust functions to be separated from the sealed case body, enabling heat dissipation while maintaining water-proof and dust-proof protection of the internal components.
Solution Approach 2:
The patent introduces an intermediary structure (the covering structure with block walls) that mediates between the air flow requirements and the sealing requirements. The air channel acts as a controlled intermediary pathway that allows air to reach the ventilators while preventing direct exposure of the case interior to external water and dust.
2Object-affected harmful factors
If a closed structure is used for the electric equipment case, then water-proof and dust-proof protection is improved, but heat dissipation performance deteriorates
Solution Approach 1:
The case is segmented into a sealed main body and a separate covering structure with integrated air channels. This allows the majority of the case to remain closed and protected while the covering structure provides controlled ventilation pathways, achieving both protection and heat dissipation.
Solution Approach 2:
The case structure exhibits local quality differentiation: the main case body maintains a closed, sealed structure for protection, while the covering structure introduces localized ventilation features (air channels and ventilators) specifically where heat dissipation is needed, without compromising the overall sealed design.
3Object-affected harmful factors
If additional wind-guiding covers are added to protect against water and dust, then water-proof and dust-proof protection is improved, but device complexity increases
Solution Approach 1:
The patent merges the wind-guiding cover function into the existing covering structure. The block walls of the covering structure simultaneously serve as protective elements against water and dust while defining the air channel pathways, eliminating the need for separate wind-guiding covers and reducing overall device complexity.
Solution Approach 2:
The covering structure is designed with multi-functionality: it provides structural support, defines the air channel geometry, protects against water and dust ingress, and guides air flow to the ventilators. This consolidation of multiple functions into a single structure reduces the number of components and simplifies the overall design.
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
The solution effectively dissipates heat while maintaining water-proof and dust-proof protection, reducing the risk of component damage and eliminating the need for additional wind-guiding covers, thus optimizing the configuration space.
Implementation Method 1
The forced air cooling achieves favorable cooling effects and costs less than the water cooling. Hence, the forced air cooling is applicable to the car electric equipment case set.
Implementation Method 2
The electric equipment case can even dissipate heat by itself due to air convection.

AI summary
A car electric equipment case module includes a housing, a covering structure, an electric equipment set, and a fan. The housing has a side wall, a containing space containing the electric equipment set and a first ventilator formed on the side wall. The covering structure includes a casing assembled to the housing and a block wall connected to the casing and extending outside the side wall to cover the first ventilator. An air channel connected the first ventilator is formed between the block wall and the side wall. The fan configured in the housing provides an air flow. The air flow flows into the containing space through the air channel and the first ventilator and flows out through a second ventilator formed on the covering structure, or flows into the containing space through the second ventilator and flows out through the first ventilator and the air channel.
