Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery designs for vehicles face inefficiencies in heat dissipation, particularly since cooling devices are often placed on lower walls of the cell housing, which hinders effective heat removal during operation.
Innovation Solution
A battery design where the cooling device is positioned on the top wall of the cell housing, allowing for enhanced convective heat transport and efficient heat dissipation, with electrical poles protruding from the bottom to facilitate unobstructed installation and operation, and incorporating a pressure safety device and filling opening on the top wall for reliable gas escape and electrolyte management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the cooling device is arranged on the lower wall of the cell housing, then the installation is simplified, but the heat dissipation efficiency is reduced
Solution Approach 1:
The cooling device is inverted from the conventional lower wall position to the top wall position of the cell housing. This inversion leverages the natural convective heat transport that rises upward, allowing the cooling device to efficiently capture and remove heat as it naturally rises to the top of the battery cell, thereby resolving the contradiction between installation simplicity and heat dissipation efficiency.
Solution Approach 2:
The position parameter of the cooling device is changed from the lower wall to the top wall of the cell housing. This parameter change optimizes the heat dissipation efficiency by aligning the cooling device with the natural convective flow direction of heat rising within the battery cell, while still maintaining ease of installation through the simplified top-wall mounting approach.
2Temperature
If the cooling device is arranged on the top wall of the cell housing, then the heat dissipation efficiency is improved, but the installation becomes more complex
Solution Approach 1:
Instead of placing the cooling device on the lower wall as conventionally done, the invention inverts the arrangement by positioning it on the top wall. This inversion capitalizes on the natural upward convective heat transport, enabling superior heat dissipation efficiency while the design maintains installation simplicity through the straightforward top-wall mounting configuration.
3Ease of operation
If the electrical poles protrude from the top wall of the cell housing, then the electrical connection is facilitated, but the cooling device installation is obstructed
Solution Approach 1:
The invention employs asymmetric design by positioning the electrical poles on the lower wall while placing the cooling device on the top wall of the cell housing. This asymmetric arrangement eliminates interference between the two components, allowing both the electrical connection and cooling device installation to proceed without obstruction, thereby resolving the contradiction between ease of electrical connection and cooling device installation.
