Busbar Protection Module With Pivoting Covers for Immersion Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing immersion cooling systems face risks of electrical damage and fire due to objects falling on high-voltage busbars disposed at the bottom of cooling tanks, which can cause short circuits.
Innovation Solution
The system incorporates busbar protection modules with pivotally connected covers that automatically open and close over the busbar to prevent objects from falling and include features like concave portions to guide objects into collection containers, reducing the risk of electrical contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the busbar is disposed at the bottom of the cooling tank to supply power, then the power supply function is achieved, but the risk of electrical damage and fire increases when objects fall on the busbar
Solution Approach 1:
A protection module is introduced as an intermediary between the busbar and the cooling tank environment. This module includes a cover that can close over the busbar to prevent direct contact with falling objects, while still allowing the busbar to perform its power supply function. The protection module acts as a mediator that enables both power transmission and safety protection simultaneously.
Solution Approach 2:
The protection module is divided into separate functional components: a base固定在 the cooling tank, a cover that can move independently, and a driving member that controls the cover's movement. This segmentation allows the system to maintain power supply functionality while adding protective capabilities without compromising the busbar's electrical function.
2Reliability
If protection modules are added to cover the busbar, then electrical safety is improved, but the operation space and device complexity increase
Solution Approach 1:
The cover of the protection module is designed to be movable rather than fixed. It can dynamically open when objects approach (detected by sensors) and close when no threat is present. This dynamic behavior allows the system to provide protection only when necessary, reducing unnecessary structural complexity while maintaining safety. The driving member enables this dynamic response with simple mechanical motion.
Solution Approach 2:
The protection module operates autonomously using sensors to detect falling objects and automatically activates the driving member to open or close the cover. This self-service capability eliminates the need for complex external control systems, reducing overall device complexity while maintaining effective protection. The system monitors and responds to threats without requiring additional control infrastructure.
3Ease of operation
If the cover is designed to automatically open when pushed, then the ease of operation is improved, but the mechanism complexity increases
Solution Approach 1:
The driving member utilizes dynamic mechanical principles where the cover is connected through a pivot point, allowing it to rotate open when force is applied from above. This dynamic mechanical design enables automatic opening through simple physical interaction rather than complex electronic actuators. The same mechanism also allows the cover to close automatically when the force is removed, providing ease of operation with minimal mechanical complexity.

AI summary
An immersion cooling system includes a cooling tank, a busbar and two busbar protection modules. The busbar is disposed in the cooling tank. The two busbar protection modules are disposed at opposite sides of the busbar. Each of the two busbar protection modules includes a base, a driving member and a cover. The driving member is pivotally connected to the base. The cover is pivotally connected to the driving member. Two covers of the two busbar protection modules extend toward each other to cover the busbar. When two driving members of the two busbar protection modules are pushed, the two driving members rotate to drive the two covers to move away from each other, such that the busbar is exposed between the two covers.
