Lateral Peltier Cooling Element Design to Reduce Battery System Height
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooling solutions for battery systems require significant installation space when combining cooling channels and Peltier elements, as Peltier cooling alone is inefficient and increases the height of the cooling element, making it unsuitable for compact applications.
Innovation Solution
A cooling element design featuring a cooler upper part and a cooler lower part with a Peltier element arranged laterally next to and partially overlapping the cooling channel, allowing efficient cooling without increasing the height, and utilizing a thermal insulation element to minimize condensate formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Peltier elements are added to cooling channels for efficient cooling, then cooling efficiency is improved, but installation space and height increase
Solution Approach 1:
The Peltier element is merged with the cooling channel structure by positioning it laterally adjacent to the cooling channel and making it bear against the cooling channel walls. This integration allows both the Peltier element and cooling channel to occupy overlapping spatial volumes, thereby improving cooling efficiency without proportionally increasing installation space.
Solution Approach 2:
The Peltier element is arranged in a lateral dimension adjacent to the cooling channel rather than stacking it vertically above or below. This dimensional arrangement allows the Peltier element to utilize lateral space next to the cooling channel, preventing height increase while maintaining effective cooling contact through the lateral bearing arrangement.
2Reliability
If Peltier elements are used for cooling, then cooling capability is improved, but the height of the cooling element increases
Solution Approach 1:
The Peltier element is positioned laterally adjacent to the cooling channel rather than vertically stacked, utilizing the lateral dimension instead of the vertical dimension. This arrangement ensures that the height of the cooling element is determined primarily by the cooling channel dimensions, not by the Peltier element height, thus avoiding height increase while maintaining cooling capability.
Solution Approach 2:
The Peltier element is nested within the lateral boundaries of the cooling channel structure, with its height being contained within or less than the cooling channel height. This nesting arrangement allows the Peltier element to be accommodated within the existing vertical envelope of the cooling channel, preventing overall height increase.
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
This design enables efficient cooling with minimal installation space, optimizing temperature transfer and reducing the overall height of the cooling element, while maintaining effective heat dissipation through both cooling channels and Peltier elements.
Implementation Method 1
the Peltier element bears laterally on at least two sides against one or two cooling channels
Implementation Method 2
a cooling element can form cooling channels through which a cooling medium, such as water, can flow, so that heat, for example from battery cells in contact with the cooling element, is transferred to the cooling element and further to the cooling medium
