Charging Pile Case Partitioning for Washable Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing case bodies for charging piles face challenges in cleaning the heat dissipation assembly due to its integration with electrical components in the same chamber, making direct cleaning inconvenient.
Innovation Solution
The case body design separates the heat dissipation assembly from the electrical components by dividing the shell into two cavities, allowing cleaning water to flow directly into the second cavity through air inlets and outlets, thus facilitating the cleaning of the heat dissipation assembly without the need to remove it from the shell.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If heat dissipation assembly and electrical components are mounted in the same chamber, then the structure is compact and simple, but the heat dissipation assembly cannot be cleaned directly and requires removal for cleaning
Solution Approach 1:
The patent divides the internal space of the case body into two separate chambers: a first chamber for electrical components and a second chamber for heat dissipation assembly. This segmentation allows the heat dissipation assembly to be accessed and cleaned independently through the air inlet opening, while maintaining overall structural compactness. The partition wall between chambers ensures functional separation while enabling differential maintenance access.
2Ease of operation
If heat dissipation assembly is separated into a different chamber, then direct cleaning becomes possible, but the structural complexity increases
Solution Approach 1:
The air inlet opening serves multiple functions: it provides ventilation for heat dissipation during normal operation and serves as the access point for cleaning the heat dissipation assembly. This multi-functionality reduces the need for additional separate openings or access points, thereby minimizing structural complexity while enabling direct cleaning capability.
Solution Approach 2:
The heat dissipation assembly is extracted into a separate second chamber that is accessible through the air inlet opening. This extraction allows the heat dissipation assembly to be cleaned in place without removing it from the case body, as the partition wall configuration enables access through the existing air inlet while maintaining separation from electrical components.
3Volume of stationary object
If all components are in one chamber, then the case body volume is minimized, but cleaning requires component removal which reduces productivity
Solution Approach 1:
By segmenting the internal space into two chambers with the heat dissipation assembly in the second chamber, the design enables direct cleaning access through the air inlet without requiring complete disassembly. This segmentation maintains compact overall volume while significantly improving cleaning efficiency by allowing maintenance personnel to clean the heat dissipation assembly in place.

AI summary
A case body and charging pile. The case body includes a shell, a partition, electrical components and a heat dissipation assembly. The partition is arranged in the shell so as to divide the shell into a first cavity of sealed cavity and a second cavity, and the shell is provided with an air inlet and an air outlet in communication with the second cavity; the electrical component is arranged in the first cavity; the heat dissipation assembly is arranged in the second cavity and used for dissipating heat to the electrical component. With the shell being divided into a first cavity and a second cavity, the heat dissipation assembly is separated from the electrical components. Therefore, cleaning water may be directly flushed into the second cavity through the air inlet and/or the air outlet to clean the heat dissipation assembly.
