Cooling distribution unit and assembling/disassembling method thereof
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooling distribution units require complex and laborious processes to disassemble and replace pumps, as they are fixed directly and necessitate high forces or screw structures, leading to inefficient pump swapping.
Innovation Solution
A cooling distribution unit with a removable unit and an adjustment mechanism featuring guiding structures and a fulcrum part, allowing the unit to be locked or detached by simply rotating the adjustment mechanism, simplifying the assembly and disassembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a screw structure is used to disassemble the pump, then the pump can be removed after the nut is completely separated, but the disassembling process becomes slow and complicated
Solution Approach 1:
The connection structure is divided into a quick-release component on the pump and a corresponding receptacle on the CDU body. This segmentation allows the pump to be disconnected in one quick motion rather than requiring multiple screw rotations, directly resolving the contradiction between ease of removal and time consumption.
Solution Approach 2:
Instead of using a traditional screw-threaded connection where separation requires reverse rotation through multiple turns, the invention inverts the approach by using a quick-release mechanism with a receptacle and plunger system. This allows the pump to be removed by simply pulling or pressing a release mechanism, completely reversing the traditional disassembly sequence and dramatically reducing time and effort.
2Ease of operation
If significant force is applied to disassemble the quick release pump, then the pump can be detached, but the disassembling process requires excessive effort
Solution Approach 1:
A receptacle structure acts as an intermediary between the pump's quick-release component and the CDU body. This intermediary provides a guided path and mechanical advantage, allowing the pump to be detached with minimal force through a simple pulling or pressing motion on the release mechanism, rather than requiring direct high-force separation.
Solution Approach 2:
The quick-release mechanism incorporates dynamic elements such as spring-loaded plungers or cam-actuated release systems. These dynamic components store and release mechanical energy, enabling the pump to be detached with minimal user effort. The spring or cam mechanism amplifies a small input force into sufficient separation force, resolving the contradiction between ease of operation and force requirement.
3Device complexity
If pumps are directly fixed in the cooling distribution units, then the structure is simple, but the pump cannot be quickly released or hot swapped
Solution Approach 1:
The pump assembly is segmented from the CDU body through a removable connection interface. The pump unit becomes a separate, self-contained module with its own mounting structure that can be independently removed and replaced. This segmentation enables hot swapping while maintaining overall structural simplicity through standardized connection points.
Solution Approach 2:
The quick-release connection structure serves multiple functions: it provides mechanical attachment, enables rapid removal, and allows for hot swapping without requiring system shutdown. This multi-functional design achieves high productivity for pump replacement while keeping the overall device complexity low through a universal connection standard that can be applied to multiple pump units.

AI summary
A cooling distribution unit includes a main body, a removable unit and an adjustment mechanism. The main body includes a first guiding structure. The removable unit includes a casing, a pump and a second guiding structure. The first guiding structure and the second guiding structure are coupled with each other. The adjustment mechanism includes a guiding slot and a fulcrum part. The guiding slot has a front end and a rear end. A distance between a center of the front end of the guiding slot and the fulcrum part is greater than a distance between a center of the rear end of the guiding slot and the fulcrum part. While the removable unit is locked on the main body or detached from the main body, the first guiding structure or the second guiding structure is disposed within the guiding slot.
