Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid cooling systems face issues with coolant overflow and leakage during filter element replacement or repair, due to the liquid level not being maintained below the upper opening, leading to potential blockages and inefficiencies.
Innovation Solution
A coolant filter structure with a container body, upper cover, fluid inlet, and filter element design that maintains the liquid level below the upper opening, featuring a cap bump or integrated filter element to prevent overflow and leakage, along with an exhaust valve to discharge air and a pipeline design for easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the liquid cooling system uses a traditional filter element replacement design, then the filter element can be accessed for maintenance, but the coolant will overflow and leak during replacement
Solution Approach 1:
The patent applies preliminary anti-action by designing a cap bump that protrudes into the container body to preemptively prevent coolant overflow. The cap bump creates a physical barrier that limits the maximum liquid level, preventing coolant from spilling out during filter element replacement operations before the problem can occur.
Solution Approach 2:
The patent uses an intermediary approach by introducing a cap bump as a mediating structure between the container body and the coolant. This cap bump acts as a buffer element that mediates the interaction between the liquid level and the container opening, allowing filter element access while preventing coolant leakage.
2Object-generated harmful factors
If the liquid level is maintained below the upper opening to prevent overflow, then coolant leakage is avoided, but air blockage occurs in the filter element
Solution Approach 1:
The patent applies segmentation by separating the functions of liquid level control and air venting into distinct components. The cap bump handles liquid level control to prevent overflow, while a dedicated exhaust valve handles air venting. This segmentation allows each component to optimize its specific function without compromising the other.
Solution Approach 2:
The patent introduces an exhaust valve as an intermediary component that specifically addresses the air blockage problem. This valve acts as a dedicated mediator for gas evacuation, allowing air to be vented from the system while maintaining the liquid level below the upper opening to prevent coolant leakage.
3Ease of repair
If the container body is detached for filter element replacement, then the filter element can be accessed, but coolant overflow and leakage occur
Solution Approach 1:
The patent segments the filter element from the container body, allowing the filter element to be accessed and replaced independently through the upper opening without detaching the entire container body. This segmentation enables maintenance operations while maintaining the integrity of the coolant containment system.
Solution Approach 2:
The cap bump provides preliminary anti-action by preventing coolant overflow before it can occur during filter element replacement. This allows the filter element to be accessed through the upper opening without the risk of coolant leakage, eliminating the need to detach the container body.
4Productivity
If the filter element is replaced without draining the coolant, then system operation is maintained, but coolant overflows due to shaking
Solution Approach 1:
The cap bump provides preliminary anti-action by creating a physical limit to the liquid level that prevents coolant overflow during filter element replacement. This allows maintenance to be performed without draining the coolant system, maintaining continuous operation while preventing the harmful overflow effect.
Solution Approach 2:
The cap bump acts as a beforehand cushioning element that prepares the system against potential coolant overflow. By limiting the maximum liquid level in advance, it cushions against the harmful effects of shaking or agitation that occur during filter element replacement operations.

Function Achieved in This Case
Prevents coolant overflow and leakage during filter element replacement or repair, ensuring efficient liquid filling and purifying capabilities without disrupting the system's operation.
Implementation Method 1
The fluid inlet is arranged below the container body, wherein the coolant is allowed flowing into the container body from a bottom of the container body through the fluid inlet
Implementation Method 2
The filter element vertically penetrates the container body... the coolant in the container body is allowed to flow through the filter element
Implementation Method 3
The fluid outlet is arranged on a lateral side of the container body... the coolant in the container body is allowed to flow through the filter element and be discharged from the fluid outlet
