Battery Pack Cooler Structure for Condensation Water Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Condensation water forms on the upper surface of a cooler in battery packs and can drip from the outer peripheral edge, leading to potential damage and electronic component issues.
Innovation Solution
An energy storage device with a cooler design that includes a blocking portion extending along the upper surface to prevent condensation water from flowing towards the outer peripheral edge, and optionally incorporating an elastic member and thermal insulation material to manage and reduce water accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a vapor chamber (cooler) is used to cool energy storage modules, then cooling effectiveness is improved, but condensation water forms and drips from the outer peripheral edge causing damage
Solution Approach 1:
The cooler is divided into a first portion (main body) and a second portion (protruding blocking structure). This segmentation creates a physical barrier that divides the cooling surface into functional zones: one for heat dissipation and another for condensation water management, preventing water from reaching the outer peripheral edge
Solution Approach 2:
The second portion acts as an intermediary structure between the condensation water formation area and the outer peripheral edge. This intermediate blocking portion intercepts condensation water before it can flow to the edge, serving as a protective barrier while maintaining the cooler's overall cooling function
2Temperature
If the cooler surface area is increased to improve cooling, then heat dissipation is enhanced, but more condensation water forms and accumulates
Solution Approach 1:
Different portions of the cooler are given different functional qualities: the first portion is optimized for heat dissipation with maximum surface area, while the second portion is specifically designed for condensation water blocking. This local differentiation allows the cooler to simultaneously achieve effective cooling and condensation management without compromising either function
3Object-affected harmful factors
If a blocking portion is added to prevent condensation water flow, then water dripping is reduced, but device complexity increases
Solution Approach 1:
The blocking portion (second portion) is merged with the cooler body (first portion) to form an integrated structure. Rather than adding a separate independent component, the blocking function is combined with the cooling structure itself, minimizing additional complexity while achieving effective condensation water prevention
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 blocking portion effectively minimizes the flow and dripping of condensation water, reducing damage to the cooler and electronic components, and enhances the device's reliability by absorbing and evaporating moisture.
Implementation Method 1
a second portion protruding upward from the first portion. The second portion is configured to block condensation water formed on a second upper surface of the first portion from flowing toward an outer peripheral edge of the first portion
Implementation Method 2
The second portion may be an elastic member. With this configuration, the load transferred from the upper cover to the second portion can be absorbed by the elastic force of the second portion
Implementation Method 3
The energy storage device may further include a thermal insulation material disposed on the second upper surface of the first portion. This configuration can reduce the area of the exposed portion of the second upper surface compared to the case where the thermal insulation material is not disposed on the second upper surface. This can reduce the amount of condensation water that forms on the second upper surface

AI summary
An energy storage device includes an energy storage module, and a cooler disposed above the energy storage module. The cooler includes a cooler body (first portion) extending along an upper surface (first upper surface) of the energy storage module, and a blocking portion (second portion) provided so as to protrude upward from the cooler body. The blocking portion is provided so as to block the condensation water generated on the upper surface (second upper surface) of the cooler body from flowing toward the outer peripheral edge of the cooler body.
