Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioner designs for energy storage containers result in uneven heat dissipation, leading to increased temperatures and reduced battery lifespan due to insufficient air supply and long internal air circulation paths, which are costly and inefficient.
Innovation Solution
A chassis design that utilizes a fan to circulate air between the electric apparatus and an accommodation cavity, with a heat exchanger positioned close to the air vent to enhance heat exchange efficiency, and a thermodynamic cycle using a heat exchange working substance to facilitate internal-to-external and external-to-internal heat exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If an integrated air conditioner is mounted on both sides of the chassis to cool batteries, then the temperature control system can be implemented, but electric apparatuses away from the air conditioner have poor heat dissipation effect due to insufficient air supply
Solution Approach 1:
The patent divides the chassis into multiple air circulation zones with independent air vents and fans for each electric apparatus. Each apparatus has its own air inlet and outlet vents, allowing localized air circulation and heat dissipation. This segmentation ensures that each electric apparatus receives sufficient air supply for effective heat dissipation, resolving the issue of poor heat dissipation for apparatuses away from the air conditioner.
Solution Approach 2:
The patent introduces air vents and fans as intermediary components between the air conditioner and electric apparatuses. These intermediaries distribute cooled air uniformly to each apparatus and facilitate air circulation, ensuring that heat dissipation is effective for all apparatuses regardless of their distance from the air conditioner.
2Temperature
If an integrated air conditioner is used with long internal air circulation path, then the system can cool the chassis, but air resistance is high and temperature control efficiency is low
Solution Approach 1:
The patent segments the air circulation system into multiple independent loops, each serving a specific electric apparatus. This creates shorter air circulation paths with reduced air resistance, improving temperature control efficiency while maintaining effective cooling across the entire chassis.
Solution Approach 2:
The patent optimizes the spatial arrangement of air vents and circulation paths to create more direct and efficient cooling routes. By reconfiguring the air circulation architecture, the system reduces path length and air resistance, thereby improving temperature control efficiency.
3Adaptability or versatility
If electric apparatuses are placed at different distances from the air conditioner, then the chassis layout is flexible, but apparatuses far from the air conditioner experience insufficient air supply
Solution Approach 1:
The patent implements segmented air supply systems with dedicated air vents and fans for each electric apparatus. This allows each apparatus to receive independent and sufficient air supply regardless of its position in the chassis, maintaining flexible layout arrangements while ensuring adequate cooling for all components.
