Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooling solutions for battery systems, such as those using cooling ducts and Peltier elements, require significant construction space and are not very efficient, making them unsuitable for compact applications like motor vehicles.
Innovation Solution
A cooling element design that integrates a Peltier element at the height of the cooling ducts, allowing the Peltier element to occupy lateral space instead of increasing the height, combined with a flat top and bottom cooling element parts and a carrier element with heat insulation, enabling efficient thermal transfer without expanding the overall height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple cooling element with cooling ducts is used, then the construction is simple, but cooling efficiency is insufficient
Solution Approach 1:
The patent combines a cooling element with cooling ducts and a Peltier element into a single integrated cooling device. The Peltier element is positioned to lie at least partially at the height of the cooling duct, allowing it to occupy lateral space rather than increasing overall height. This merging of cooling mechanisms improves cooling efficiency while maintaining construction simplicity.
2Reliability
If additional cooling by Peltier elements is added to cooling ducts, then cooling efficiency is improved, but construction space increases
Solution Approach 1:
The Peltier element is arranged to lie at least partially at the height of the cooling duct, which means it occupies lateral space rather than increasing the overall height of the cooling element. This dimensional arrangement allows the cooling element to maintain a compact form factor while incorporating both cooling ducts and Peltier element for improved cooling efficiency.
3Device complexity
If cooling solely by Peltier elements is used, then construction is simplified, but cooling efficiency is not sufficient
Solution Approach 1:
The patent merges cooling ducts and a Peltier element into a single integrated cooling device where the Peltier element is positioned to lie at least partially at the height of the cooling duct. This combination leverages both passive cooling through ducts and active cooling through the Peltier element, achieving sufficient cooling efficiency while maintaining construction simplicity.

Function Achieved in This Case
This design achieves efficient cooling of battery systems with reduced construction space requirements, optimizing thermal transfer and minimizing the formation of condensate, while maintaining a compact form factor.
Implementation Method 1
a Peltier element is arranged, resting against the bottom cooling element part, so as to lie at least partially at the height of the cooling duct
Implementation Method 2
heat from battery cells resting against the cooling element is transferred to the cooling element, and further on to the cooling medium
